Short Term Regulatory Changes to the Lead and Copper Rule

Executive Summary

	The Environmental Protection Agency (EPA) is making seven targeted
regulatory changes to the national primary drinking water regulations
(NPDWR) for lead and copper. The intended effect of these regulatory
changes is to strengthen the implementation of the Lead and Copper Rule
(LCR) in the areas of monitoring, customer awareness, and lead service
line replacement. Some of these changes clarify the intent of the LCR
for provisions that have generated questions. Other provisions
reconsider LCR requirements in light of recent experiences regarding
implementation of the rule. These changes are expected to ensure and
enhance more effective protection of public health through the reduction
of lead exposure. The changes included in today’s action do not affect
the lead or copper maximum contaminant level goals, the Action Levels,
or the basic regulatory requirements.

	This Economic Analysis describes the estimates of annual costs for the
seven regulatory changes to utilities and States, including costs
associated with administrative, monitoring, sampling, reporting, and
public notification activities. One-time, upfront costs of rule review
and rule implementation are also estimated. There are two types of
annual costs that may result from the rule changes – direct and
indirect. Direct costs are from those activities that are specified by
the rule change, such as costs for additional monitoring or distribution
of consumer notices. A second type of cost may also result when systems
and States use the information generated by directly–related rule
activities to modify or enhance practices to reduce lead levels. These
indirect costs, and related health risk reductions, are not quantified
for the purposes of this analysis, but are described qualitatively in
Section 5. Exhibit ES-1 summarizes the expected direct and indirect cost
impacts for the seven regulatory changes.

	Six rule changes are expected to result in direct costs: Regulatory
Changes III.A, III.C, III.D, III.E, III.F, and III.G. For these
potential rule changes, costs could be incurred in the areas of system
reporting, tap water monitoring and public education for systems, and
State review and public education for States/Primacy Agencies. Exhibit
ES-2 summarizes the annual direct costs estimated for each rule change.
Exhibit ES-3 summarizes the one-time direct costs associated with
implementing the rule changes.

With regards to potential benefits resulting from the changes, the
intent of this rulemaking is to improve implementation of the lead and
copper regulations by clarifying monitoring, reporting, and notification
requirements, and modifying the lead service line test-out procedure.
The revisions do not affect the action levels, treatment techniques such
as corrosion control requirements, or other provisions in the existing
rule that directly determine the degree to which the rule reduces risks
from lead and copper. 

However, the increase in administrative activities that will result from
the revisions will result in the generation of new information (e.g.,
more monitoring data, some of which may show exceedances), and may
prompt some systems or individuals to respond to this new information by
taking measures to abate lead and copper exposures and thus reduce the
associated risk. Also, the requirement that treatment changes be
approved by the primacy agency prior to implementation will provide an
additional opportunity to identify possible adverse impacts due to
treatment changes, which may lower the risk to consumers. Because the
precise impact of these revisions on the behavior of individuals and
systems is not known, EPA has not quantified the changes in health
benefits associated with these revisions. EPA does expect that overall
benefits from the LCR will increase, as a result of the indirect effect
of the revisions on the actions of individual consumers and systems.

1	Introduction

	This document presents an analysis of the costs and potential impacts
of the Short Term Regulatory Changes to the Lead and Copper Rule. 

	This section provides a summary of the regulatory changes in Section
1.1. Section 1.2 outlines the organization of this document.

1.1 Summary of Changes

	The seven targeted regulatory changes to the Lead and Copper Rule (LCR)
that are the focus this document are summarized below. 

Summary of Short Term Targeted Regulatory Changes

#	Revision	Purpose of Revision

Monitoring

III.A	Minimum number of samples required	To address confusion about
sample collection

III.B	Definitions for compliance and monitoring periods	To clarify when
compliance and monitoring periods begin and end

III.C	Reduced monitoring criteria	To prohibit systems that exceed the
lead Action Level from initiating or remaining on reduced monitoring
based solely on results of water quality parameter monitoring

Treatment Processes

III.D	Advanced notification and approval requirement for water systems
that intend to make any change in water treatment or add a new source of
water that could affect the system’s optimal corrosion control	To
require systems to obtain state approval to add a new source of water or
change a treatment process prior to implementation

Customer Awareness

III.E	Notification of sampling results	To require utilities to provide
sampling results to consumers who are occupants of homes or buildings
that are tested for lead and copper, as part of the utility’s
monitoring program

III.F	Public Education Requirements	To modify public education
requirements by changing the content of the message to be provided to
consumers, how the materials are delivered to consumers, and the
timeframe for delivery

Lead Service Line Replacement

III.G	Reconsideration of lead service lines deemed replaced through
testing	To require that systems reevaluate lead service lines classified
as “replaced” through testing if the system resumes a lead service
line replacement program



1.2		Summary of Differences With the EA for the Proposed Rule

	This EA reflects the final version of the Short Term Changes to the
Lead and Copper Rule.  In comparison with the EA that accompanied the
proposed Rule, the costs in the EA for the Final Rule have been updated
to reflect a 4th Quarter 2006 price level.  In addition, some burden and
cost estimates have been revised based on feedback received in comments
on the proposed Rule.  Finally, the burden and cost estimates for some
of the regulatory changes have been modified to reflect specific changes
to the requirements.  The differences between the Final Rule and the
proposed Rule are summarized in the Appendix L.

    

1.3		Document Organization

	The rest of this document is organized into the following sections:

Section 2 identifies public health concerns addressed by the rule and
provides a summary of the regulatory history of lead in drinking water,
including the recent review of national implementation of the LCR. It
also explains the statutory authority for promulgating the rule changes
and economic rationale for choosing a regulatory approach.

Section 3 describes the changes in greater detail and reviews
alternative approaches considered.

Section 4 presents an estimate of the direct costs of implementing the
rule changes to utilities and State/Primacy Agencies.

Section 5 discusses the potential indirect cost and health risk impacts
that may result from the rule changes.

Section 6 discusses analyses performed to evaluate the effects of the
rule as specified by various administrative requirements.

2	Need for the Rule

	The purpose of the Lead and Copper Rule (LCR) is to protect populations
from exposure to lead in drinking water to reduce potential health risks
associated with lead. Recent highly publicized incidences of elevated
drinking water lead levels prompted EPA to review and evaluate the
implementation and effectiveness of the LCR on a national basis. As a
result of this multi-part review EPA identified the targeted rule
changes that are the subject of this Economic Analysis. These targeted
changes are intended to strengthen the implementation of the LCR in the
areas of monitoring, customer awareness, and lead service line
replacement. Some of the changes clarify the intent of the LCR for
provisions that have generated questions. Other provisions reconsider
LCR requirements in light of recent experience. These changes are
expected to ensure and enhance more effective protection of public
health through the reduction in lead exposure.

	The following section more fully discusses the need for the targeted
rule changes by first summarizing the health effects associated with
exposure from lead to emphasize the on-going need for reducing that
exposure. Next, context on the regulatory history of the LCR is
provided. EPA’s recent review of the LCR that resulted in the
identification of the targeted rule changes (among other actions) is
described. The section concludes with a description of the regulatory
authority and economic rationale for the regulation.

2.1		Public Health Concerns Related to Lead and Copper Exposure 

		Although lead is a naturally occurring metal, the highest
concentrations of lead are a result of human activities (ATSDR, 1999).
For example, sources of lead include lead-based paint, contaminated
soil, contaminated water, lead crystal or lead-glazed pottery or
porcelain, and industrial processes burning lead-based materials. Lead
exposure can cause many serious health effects, especially for children.
For this reason, EPA places a high priority on reducing lead blood
levels (Grumbles, 2004). 

		Lead can enter the body if it swallowed or inhaled. If contaminated
food, drink, soil, lead-based paint chips, or other objects covered in
lead dust are ingested, lead will be delivered to the stomach. After
reaching the stomach, a small portion of lead will enter the
bloodstream, while the other portion will be excreted in urine or feces.
In general, a higher portion of lead will enter the bloodstream for
children than for adults (ATSDR, 1999). Once in the blood stream, lead
can be deposited in soft tissues, bones, and/or teeth. If lead particles
or dust are inhaled, lead will first enter the lungs and then be
delivered to the bloodstream. 

		Lead exposure can result in the following health effects: lead can
damage the brain and kidneys, cause infertility in both men and woman,
increase blood pressure in adults, and harm the nervous system causing
nerve disorders and muscle and joint pain. Life long exposure to lead
above the Maximum Contaminant Level (MCL) may lead to strokes and kidney
disease.

		Certain populations are at higher risk because they are exposed to
lead more often and/or because they are more sensitive to the same
exposure than an average individual. Children are more vulnerable to
lead exposure because they are both typically exposed to lead more often
and because they are more sensitive to lead. Children are more likely to
be exposed to lead since they often place their hands on many objects,
such as toys, which might be covered in lead dust, and then place their
hands in their mouths. Infants can also be exposed through an exposed
mother’s breast milk. Children are more sensitive to lead because
children’s bodies absorb more of the ingested lead than adults (ATSDR,
1999). In addition, lead exposure can result in greater health risks in
children as their nervous system is still developing. Health effects in
children may include delayed mental and physical development, decreased
IQ, and slight deficits in attention span, hearing, and learning
(Grumbles, 2004). During 1999-2000, approximately 2 percent of children
between the ages of 1 and 5 have blood levels that exceeded CDC’s
level of concern, 10 mg/dL (CDC, 2003).

		Reducing lead exposure for pregnant women is another primary concern
for EPA (Grumbles, 2004). If a mother is exposed to lead, that lead can
be passed on to the developing fetus. Because their nervous systems are
just beginning to develop, fetuses are especially vulnerable to lead
exposure. 

		The Maximum Contaminant Level Goal (MCLG) describes the lowest level
of exposure to a contaminant that does not cause any potential health
problems. EPA determined that the MCLG for lead should be zero, since
there is no known safe level of lead in blood (EPA, 2005). Thus, any
exposure to lead, at any concentration, is considered harmful,
especially for young children and pregnant women. 

		

		The rule changes are needed to continue the health protection afforded
by the LCR though more timely and useful information regarding lead
exposure. These changes will also promote effective implementation of
the LCR provisions that protect citizens from lead in drinking water. 

2.2		 Regulatory History

		The following section provides a chronology and overview of regulatory
actions affecting the permitable level of lead and copper in drinking
water. 

		Drinking Water Regulations Enacted Prior to 1991

		As required by the Safe Drinking Water Act (SDWA), EPA set the
National Interim Primary Drinking Water Regulation for lead in drinking
water to 50 parts per billion (ppb) in 1975. This standard was not
enforceable and did not require utilities to sample at taps to determine
if they were in compliance.

		To limit the amount of lead reaching customer’s taps, Amendments to
SDWA in 1986 banned the installation or repair of lead pipes, fixtures,
solders, and fluxes in any facility that provides water for human
consumption. As defined in section 1417 (d), “lead free” solders and
fluxes may not contain more than 0.2 percent lead and “lead free”
pipes, pipe fittings, and well pumps may not contain more than 8.0
percent lead. In addition, the 1986 SDWA Amendments directed EPA to
revise the regulations for lead and copper in drinking water. In
response to this directive, the Agency proposed revisions in 1988, and
issued the Lead and Copper Rule in 1991. 

		To limit lead exposure to one of the most sensitive populations,
children, the Lead Contamination Control Act (LCCA) in 1988 required
schools to test drinking water and recall drinking water coolers that
leached lead. Furthermore, the LCCA banned new drinking water coolers
with lead parts. 

		Lead and Copper Rule 1991

		On June 7, 1991, EPA promulgated the Lead and Copper Rule (56 FR
26460; LCR), which set the maximum contaminant level goals (MCLGs) and
national primary drinking water regulations (NPDWRs) for lead and
copper. The rule aimed to maximize human health protection by reducing
lead and copper levels at consumers’ taps as close to the MCLG, 0 for
lead and 1.3 ppm for copper, as is technologically possible. Since
limited technology and resources made the MCLG unfeasible, EPA set
Action Levels at 0.015 mg/L for lead and 1.3 mg/L for copper. Compliance
is based on the 90th percentile of tap water samples. 

		To reduce lead and copper concentrations below the Action Level, the
LCR specified that community water systems (CWSs) and non-transient
non-community water systems (NTNCWSs) must conduct periodic monitoring
at the tap and reduce water corrosivity, since corrosive water can
increase the amount of lead and copper that is leached from service
lines and plumbing materials made of lead and/or copper. The rule also
required the following.

Public notification when lead in treated drinking water exceed the lead
Action Level

Treatment of source water if it significantly contributed to high levels
of lead or copper

Replacement of lead service lines in the distribution system if lead
levels continued to exceed the Action Level

Implementation of this rule was phased in based on system size, whereby
the largest systems began monitoring in 1992, and the smallest systems
began monitoring in 1993. 

		Proposed Changes to the Lead and Copper Rule 1996

		On April 12, 1996, EPA published a set of proposed minor revisions to
improve implementation of the Lead and Copper Rule. Many of the changes
were based upon recommendations made by a work group composed of
Headquarters and Regional EPA staff, and State drinking water officials.
Other changes were a result of legal challenges to the 1991 Lead and
Copper Rule brought on by the American Water Works Association (AWWA)
and the Natural Resources Defense Council (NRDC).

		The goal of the proposed changes was to promote consistent, national
implementation of the LCR, and streamline and reduce reporting burden.
Proposed changes included optimizing corrosion control, streamlining
monitoring processes, guidance for site selection, requirements for
public education, guidance for analytical processes, and clarification
of reporting requirements. In addition, EPA requested comments on
paperwork burden reductions, many of which were previously suggested,
but EPA did not have sufficient time to consider for LCR 1991.

		The minor revisions to the LCR that were ultimately adopted are
discussed below under “Lead and Copper Rule Minor Revisions 2000.”

		Safe Drinking Water Act 1996

		The 1996 Amendments to SDWA added that “lead free” plumbing
fittings and fixtures must meet standards established under section
1417(e) (42 U.S.C. 300g–6(e)). Section 1417(e) of the SDWA says that
either a voluntary standard must be accepted within a year or EPA must
issue a regulation within two years. Furthermore, if a voluntary
standard is to be accepted, the Administrator must provide technical
assistance to a qualified third-party in the development of the
voluntary standard and associated testing protocols for examining lead
leaching from new plumbing fittings and fixtures.

		In response, EPA published in the Federal Register (FR Vol. 62, No.
163, 44684, Aug. 22, 1997) their view that NSF 61, Section 9 satisfies
the requirement of Section 1417(e). Specifically, EPA felt that NSF 61,
Section 9 is an established voluntary standard and therefore, the
obligation to issue a new regulation was not triggered. As a result, any
new plumbing fitting and fixtures must be NSF certified. 

		Lead and Copper Rule Minor Revisions 2000

		On January 12, 2000, EPA published final minor revisions to the Lead
and Copper Rule (LCRMR) based on the comments and discussions of the
proposed revisions in 1996. The minor revisions streamline requirements,
promote consistent national implementation, and in many cases, reduce
the burden for CWSs and NTNCWSs water systems. The changes fall into the
following categories: demonstration of optimal corrosion control, lead
service line replacement requirements, public education requirements,
monitoring requirements, analytical methods, reporting and record
keeping requirements, and special primacy considerations.

		EPA also accepted the definition of “lead free” as defined in the
SDWA.

		The LCRMR did not change the Action Levels, MCLGs, or the rule’s
basic treatment requirements. 

2.3		Comprehensive Review of the LCR

		The minor changes to the Lead and Copper Rule described in this
document were identified through a comprehensive national review of
compliance and implementation of the Lead and Copper Rule. The review
was initiated in response to high profile Action Level exceedances
experienced by the District of Columbia Water and Sewer Authority (DC
WASA). The purpose of the review was to answer three questions with
regards to lead in drinking water:

Is this a national problem? Does a large percent of the population
receive water that exceeds the lead Action Level? Do a large number of
systems fail to meet the lead Action Level?

 

How well has the rule worked to reduce lead levels in systems over the
past 12 years, particularly in systems that had demonstrated high lead
levels in the initial rounds of sampling? 

Is the rule being effectively implemented today, particularly with
respect to monitoring and public education requirements? 

		The comprehensive review consisted of several elements, including a
series of workshops designed to elicit issues, comments, and suggestions
from stakeholders on particular topics, a review of data to evaluate the
effectiveness of the rule, and a review of LCR implementation by States
and utilities. The following section summarizes the DC WASA situation
that prompted the comprehensive review, describes in greater detail the
elements of the review, and presents EPA’s findings and next steps
resulting from the review.

		DC WASA’s Experience with Elevated Lead Levels in Drinking Water

		DC WASA is a utility that distributes drinking water to over 500,000
residential, commercial, and governmental customers in the District of
Columbia. The water that DC WASA distributes is purchased from and
treated by the Washington Aqueduct, a division of the US Army Corps of
Engineers.  

		From 1994 through 1999, DCWASA met the Action Level for lead under the
LCR and went on reduced monitoring. In August 2002, DCWASA reported to
EPA that the 90th percentile of 53 tap water samples for the compliance
period of July 1, 2001- June 30, 2002 exceeded the Action Level of 15
ppb, at a value of 75 ppb. Subsequent tap sampling also indicated Action
Level exceedances for the period of January - June of 2003 (40 ppb 90th
percentile from 104 samples) and July - December of 2003 (63 ppb 90th
percentile from 108 samples). As per the LCR, the Action Level
exceedances triggered DC WASA to undertake tap monitoring on a regular
(i.e., not reduced) schedule, public education, and lead service line
replacement.

		Local media coverage of the exceedances and the results of lead
service line testing elevated the visibility of DC WASA’s lead levels.
Multiple hearings were conducted before House and Senate committees in
2004 and 2005. EPA conducted a compliance audit that resulted in an
Administrative Order that detailed alleged weaknesses in DC WASA’s
implementation of the LCR including the following.

	Failure to take samples within the monitoring period

	Failure to conduct follow-up monitoring of partially replaced lead
service lines

	Failure to comply with requirements for public service announcements

	Not using required language in written materials provided to customers

	Failure to report samples and Action Level exceedance

	Failure to perform required activities following exceedance of the Lead
Action Level in the July 2000 - June 2001 monitoring period

	Failure to report noncompliance 

		DC WASA, in coordination with EPA, the Corps of Engineers, and other
groups, implemented numerous measures to address the high lead levels,
including adding orthophosphate as a corrosion control treatment,
replacing lead service lines, and conducting sampling and research.
Early results seem to indicate the effectiveness of orthophosphate in
reducing lead levels.  Preliminary analyses from an ongoing technical
review suggest potential causes of the elevated lead levels including
the following.

	Conversion from free chlorine to chloramines for final disinfection

 

	Detachment of lead particles from piping systems

	Galvanic corrosion of lead service lines

	Grounding currents that affect corrosion of lead bearing components

	City-Wide meter replacement program

	Distribution system pH variations

	Drought conditions and resulting effects on corrosivity of DCWASA water


		With regards to the implementation of the LCR, the DC WASA experience
highlights several areas in which the LCR could be improved, including
monitoring after lead service line replacement, defining compliance and
monitoring periods, and the impact of treatment changes.

Workshops on Lead in Drinking Water

		EPA held five workshops in 2004-2005 to elicit issues and suggestions
from stakeholders on various topics related to lead in drinking water. 

	Simultaneous Compliance, May 2004, St. Louis, MO: Expert participants
from utilities, academia, state governments, and other stakeholder
groups identified issues, proposed solutions, and identified information
gaps with respect to simultaneous compliance with the LCR and other
rules such as the Total Coliform Rule, the Surface Water Treatment
Rules, and the Disinfection Byproducts Rules. Issues and suggestions
were developed for four topic areas: coagulation impacts on corrosion
control; impacts of disinfectant changes on corrosion control; corrosion
inhibitor; and distribution system management. Among the issues
identified by the group were information gaps on impacts of treatment
changes under various water quality conditions/chemistries and the need
for additional guidance on a variety of topics.

	Sampling Protocols, May 2004, St. Louis, MO: Expert participants from
utilities, academia, state governments, and other stakeholder groups
identified issues, proposed solutions, and identified information gaps
with respect monitoring and sampling under the LCR. Topic areas included
sampling frequency and triggers; sampling site selection/location;
sampling protocol; and sampling of water quality parameters. The issues
included sampling after treatment changes and Action Level exceedances
and the re-examination of flushing instructions.

	Public Education, September 2004, Philadelphia, PA: Expert participants
from utilities, governments, consumer and environmental groups, and
other stakeholder groups discussed the public education requirements
under the lead and copper rule, drinking water risk communication, and
effective communication with the public. Participants suggested ways to
improve risk communication to the public through establishing
partnerships with health departments and other groups, refining the
message content, improving delivery of the message, and spending more
time planning and evaluating the effectiveness of the risk
communication. 

	Lead Service Line Replacement, October 2004, Atlanta, GA:  Expert
participants from utilities, academia, state governments, and other
stakeholder groups discussed the challenges and problems encountered by
the participants in implementing lead service line replacement, as well
as strategies and solutions for overcoming those difficulties. Specific
topic areas addressed included monitoring, customer communications,
replacement technologies, and managing inventory. Continued sampling
after lead service line replacement and the need to notify customers of
testing results were mentioned during the discussions.

	Lead in Plumbing, July 2005, Washington, DC: Expert participants from
utilities, academia, state governments, and other stakeholder groups
discussed lead in plumbing fittings and fixtures. Topic areas included
NSF standards and testing protocols, alternative materials,
national/state/local/industry/consumer practices, and miscellaneous
issues.

Review of Data to Evaluate Effectiveness of Rule

		EPA undertook a review of the lead levels in drinking water systems
serving more than 3,300 as reported in the Safe Drinking Water
Information System/Federal Version (SDWIS/FED). Since 2002, States have
been required to report to SDWIS the 90th percentile lead concentrations
for systems serving more than 3,300. At the start of the review,
SDWIS/FED had data for only 23 percent of these systems. EPA worked with
States to expedite entry of the 90th percentile lead data. The effort
was successful, with data available for 97 percent of large systems and
91 percent of medium systems as of June 1, 2004.

		The following exhibits summarize the data on medium and large public
water systems exceeding the Action Level from SDWIS/FED as of January
27, 2005.

Summary, Lead Action Level exceedances for public water systems subject
to the Lead and Copper Rule (For data through September 13, 2004).

		Based on the data, 95.8 percent of medium and large systems reporting
data since 2000 have 90th percentile values below the Action Level.
Since 2003, it appears that number is slightly higher, with 96.9 percent
of medium and large systems under the Action Level. EPA concluded from
this data: “There does not appear to be a widespread problem with
elevated lead levels across the country comparable to that currently
being observed in the District of Columbia.” 

		

		EPA also compared Action Level exceedances for 166 large systems
serving over 50,000 from immediately after the adoption of the LCR
(1992/1993) to the current monitoring results (2000-2004), summarized in
Exhibit 3. In 1992/1993, all 166 of these systems exceeded the Action
Level. In 2000-2004, only 15 of these systems had 90th percentiles that
exceeded the Action Level, “...demonstrating that corrosion control
efforts taken by the utilities have largely been effective in
controlling lead levels.”

		In 2004, EPA carried out a review of the implementation of LCR
requirements by States. EPA asked State programs, who have primary
oversight responsibility, a number of questions about how they implement
different aspects of the LCR. The questions were centered on the
following general categories: sampling issues, calculation of the 90th
percentile value, treatment issues, lead service line replacement,
public education and enforcement. 

		Generally, the State responses to the survey indicate that the States
are following the minimum state requirements of the LCR. However, the
information provided to EPA indicates that many States may not be taking
full advantage of the opportunities to oversee implementation of the
rule. Also, the States’ responses did highlight a few areas in which
there is some confusion about the requirements of the rule as well as
areas in which some States are going above and beyond the minimum
obligations.

		Drinking Water Lead Reduction Plan

		As a result of the previous activities, EPA determined that the
current approach of the LCR has been effective in reducing drinking
water lead levels in the nation’s public water systems and that there
does not appear to be a widespread problem associated with high lead
levels in drinking water. However, EPA identified opportunities to
improve and clarify specific areas of the LCR and guidance materials.
The seven targeted rule changes that are the subject of this document
are key elements of the Drinking Water Lead Reduction Plan.

		It should be noted that EPA has also identified a number of issues
that require longer-term consideration that will continue to be reviewed
as part of potential, more comprehensive revisions to the rule or
guidance. In many cases, these issues require additional data
collection, research, and analysis to fill critical data gaps. Also,
some issues require full stakeholder involvement to support decisions.
Issues that are the subject of longer-term consideration include the
following.

Requirements for consecutive systems

Broader revisions to monitoring and lead service line replacement
requirements

Revision to lead content in plumbing fittings and fixture requirements

Short-term Regulatory Revisions and Clarifications to the Lead and
Copper Rule Workgroup

	In May 2005, EPA formed a work group to consider issues related to the
regulatory changes, called the Short-term Regulatory Revisions and
Clarifications to The Lead & Copper Rule Workgroup (LCRSTR Workgroup).
The LCRSTR Workgroup included EPA staff from a variety of Headquarters
and Regional offices, as well as representatives from State drinking
water lead programs. The LCRSTR Workgroup identified alternatives,
drafted regulatory language, and discussed issues related to the
changes.

National Drinking Water Advisory Committee Working Group on Public
Education Requirements of the Lead and Copper Rule

		

As part of the review of the LCR, EPA identified a number of issues
relating to the public education requirements of the LCR. In order to
address these concerns, the National Drinking Water Advisory Council
(NDWAC), EPA’s advisory body on the Safe Drinking Water Act, formed a
working group to consider possible revisions to the public education
requirements.   SEQ CHAPTER \h \r 1 The charge for the NDWAC Working
Group was to 1) review the current public education requirements for
lead in drinking water to make recommendations for improvements; 2)
develop recommended revised language for communicating to the public the
risk of lead in drinking water and how affected persons should respond;
and 3) review and make recommendations for changes to the means of
delivery of lead information to the public. 

The NDWAC Working Group met in person four times between October 2005
and April 2006. The Working Group was comprised of 16 individuals
representing an array of backgrounds and perspectives. Collectively,
these individuals brought into the discussion the perspectives of State
drinking water agencies, environmental and consumer groups, drinking
water utilities, small system advocates, State health officials, and
risk communication experts. The recommendations from the NDWAC Working
Group form the basis of the regulatory changes on public education
(III.F).	

2.4 	Rationale for the Regulation

		This section discusses the statutory authority of EPA to regulate lead
in drinking water and the economic rationale for choosing a regulatory
approach.

		EPA derives its statutory authority to regulate contaminants in
drinking water through the Safe Drinking Water Act. Section 1412(b) (1)
(A) of the SDWA requires EPA to establish National Primary Drinking
Water Regulations for contaminants that may have an adverse public
health effect; that are known to occur or that present a substantial
likelihood of occurring once in public water systems (PWSs), at a
frequency and level of public concern; and that present a meaningful
opportunity for health risk reduction for persons served by PWSs.

		This section addresses the economic rationale for choosing a
regulatory approach as described in Executive Order Number 12866,
Regulatory Planning and Review (USEPA

1993). OMB circular A-4 notes that the rationale for regulation is to
correct market failure or other social purposes: “The major types of
market failure include: externality, market power, and inadequate or
asymmetric information. Correcting market failures is a reason for
regulation, but it is not the only reason. Other possible justifications
include improving the functioning of government, removing distributional
unfairness, or promoting privacy and personal freedom.”

		Several of the rule changes correct inadequate or asymmetric
information. For example, regulatory change III.E requires that tap
monitoring results be provided to consumers, correcting asymmetric
information. Regulatory change III.D changes the timing of information
provision to States, again correcting asymmetric information. Additional
information is gathered under regulatory changes III.D and III.G,
correcting inadequate information. Regulatory change III.F provides for
the development of better information and the more effective
distribution of information, thereby also correcting a situation of
inadequate information.

		The other regulatory changes clarify the intent of the LCR, leading to
more effective implementation of the rule thereby improving the
functioning of government.

3	Regulatory Changes and Alternatives Considered

3.1 	Regulatory change III.A - Minimum number of samples required 

		Description of Regulatory Change

		EPA is clarifying the minimum sampling requirement for small water
systems that have fewer than five taps by making revisions to § 141.86
(c).   These revisions include a clarification that the term “taps”
means “taps that can be used for human consumption”, as opposed to
taps not used for human consumption such as hose bibs or at utility
sinks.  In addition, the revisions clarify what a system must do to meet
the minimum number of samples requirement (five), when there are fewer
than five taps available for sampling.  In this situation, those water
systems must sample all taps at least once and take repeat samples on
different days until five samples are obtained.  

		EPA  is adding a provision to § 141.86 (c) that gives States the
discretion to allow  public water systems with fewer than five taps to
collect one sample per tap that can be used for human  consumption.  The
requirement is not mandatory and NTNCWSs and CWSs that qualify must make
a request to the State in writing and must be approved by the State in
writing or by onsite verification.  Under this alternate sampling
schedule, the sample with the highest test result will be compared to
the Action Level to determine compliance.  If any sample result is above
the Action Level, it will serve as the system’s 90th percentile value.
 EPA is adding regulatory text to §141.80 to describe this new
compliance determination.  The new sampling schedule is also applicable
for NTNCWSs and CWSs that are on reduced monitoring and EPA is adding a
provision to §141.86 (d)(4)(i) for those systems.  The provision allows
the water system to reduce sampling frequency to once per year, but in
no case can the number of samples required be reduced below the minimum
of one sample per tap that can be used for human consumption.

		Rationale for Regulatory Change

		In the original Lead and Copper Rule of 1991, the term “site” is
used to refer to the number of samples collected, and there has been
confusion as to whether “site” refers to taps or physical locations.
 EPA is clarifying that sampling “sites” refer to “taps that can
be used for human consumption”. The phrase “that can be used for
human consumption” is being added to the regulations to ensure that
samples are taken from taps which would pose the highest risk for
exposure to lead, rather than from taps that are not frequently used for
human consumption. 

  

		EPA is making clarifications for NTNCWSs and CWSs with fewer than five
taps that can be used for human consumption.  In the proposal for this
rule, EPA maintained that systems must take a minimum of five samples in
order to adequately capture the variability of lead levels and that it
was more cost effective for small systems to take more samples than
install corrosion control or source treatment based on a small pool of
samples taken.  EPA is maintaining that systems must take a minimum of
five samples as part of today’s rule, however, EPA is also giving
States the discretion to offer the alternative sampling requirement of
sampling 100 percent of taps that can be used for human consumption to
water systems with fewer than five taps.  This alternative sampling
schedule alleviates any cost burden for systems  associated with taking
repeat samples and is also health protective because it does not allow
water systems to ignore a potential problem by taking repeat samples at
taps that have low lead results when they get  a high sample result 
Under the alternative sampling provision, systems would compare the
sample with the highest result to the Action Level to determine if
compliance actions, such as public education, corrosion control
treatment installation, and/or lead service line replacement, are
required.

		Alternatives Considered

Several alternative approaches were discussed by the Short-term
Regulatory Revisions and Clarifications to The Lead & Copper Rule
Workgroup (LCRSTR Workgroup). These approaches included retaining the 5
sample minimum requirement for systems, but allowing States the option
to reduce the number of samples to one per tap if the history of data
collected at the system demonstrates that levels have always been below
the Action Level with little to no variability.

3.2 	Regulatory change III.B - Definitions for compliance and
monitoring periods 

		Description of Regulatory Change 

	EPA is proposing to clarify the terms “compliance period” and
“monitoring period” for purposes of the LCR. The term “compliance
period” shall be as defined in Section 141.2 as a three-year calendar
year period within a nine-year compliance cycle. The term “monitoring
period” will refer to the specific period within the compliance period
in which a water system must perform the requirement (e.g.,
June-September).     

	

		Rationale for Regulatory Change

	This change is intended to clarify when systems are required to conduct
routine monitoring under reduced schedules and when they must begin
actions (i.e., corrosion control, public education, lead service line
replacement) to remedy a lead Action Level exceedance.	

	For systems on reduced monitoring, they must monitor either once during
each calendar year or once during each three-year compliance period. The
monitoring period is from June to September or some other four-month
period during normal operation where the highest lead levels are most
likely to occur. This change would clarify that a system that exceeds
the Action Level would be determined to be doing so as of the date on
which the monitoring period ended (e.g., on September 30). 

	This change would also require, for systems on triennial monitoring,
samples be taken during four consecutive months within the compliance
period, not over multiple years. These systems must also conduct their
monitoring every three years.

		

		Alternatives Considered 

		The Short-term Regulatory Revisions and Clarifications to The Lead &
Copper Rule Workgroup considered alternatives for defining the term
compliance period.



3.3 	Regulatory change III.C - Reduced monitoring criteria

		Description of Regulatory Change 

	Under the current rule language, systems are eligible for reduced
monitoring based on certain criteria. For small systems, these criteria
include having lead and copper levels below both Action Levels for two
consecutive monitoring periods. For all systems, the criteria include
meeting the State-designated water quality parameters with State
approval, but without meeting either the lead or copper Action Level.
The rule change specifies that if a system on reduced monitoring exceeds
the lead Action Level, the system must revert to the regular monitoring
schedule for lead tap sampling. 

		Rationale for Regulatory Change

		Monitoring lead levels at the tap is particularly critical for systems
that are exceeding the Action Level. These systems need frequent data on
the levels of lead corrosion so that they can evaluate the effectiveness
of any modifications to corrosion control treatment they may be
attempting, and to better inform their consumers of the effectiveness of
the system(s efforts to reduce lead levels.

		Alternatives Considered 

		The LCRSTR Workgroup and EPA considered including meeting the copper
Action Level for reduced monitoring under all circumstances (i.e.,
systems meeting water quality parameter requirements) as part of this
rule change. However, since the current rule does not contain additional
requirements if a copper Action Level is exceeded (such as public
education), EPA determined that copper issues will be considered as part
of longer term revisions to the rule. 

3.4 	Regulatory change III.D - Advanced notification and approval
requirement 

		Description of Regulatory Change 

		Under the current rule, Section 141.90(a) (3) requires that systems
deemed to have optimized corrosion control under §141.81(b) (3),
systems subject to reduced monitoring pursuant to §141.86(d) (4), or
systems subject to a monitoring waiver pursuant to §141.86(g) must
notify States no later than 60 days after of a treatment change or the
addition of a new source. The rule modification requires that these
systems notify States of any long-term change to be made in water
treatment process or additions of new sources in advance and the States
determine when and if these changes may be made through a formal review
and approval process. This gives systems the opportunity to consult with
their States as much as they want and to take other measures necessary
to avoid problems with corrosion. It also allows States to design
monitoring programs upfront or require additional actions for the
systems under those situations when it is necessary to ensure that
corrosion control is being maintained adequately after the change has
been made.

		Rationale for Regulatory Change

		EPA proposed that systems be required to provide advanced notification
of any change in treatment or addition of a new source and receive
approval from the State prior to making the change instead of the
existing requirement that the system had to notify the State within 60
days of making a change.  The final rule requires systems to provide
advanced notification of any change in treatment that has long term
impacts or addition of a new source and receive approval from the State
before implementing the change.  When water systems make changes to
their treatment process with long term impacts or add a new source of
water, there can be unintentional effects on the system’s optimal
corrosion control.  EPA believes that State review and approval of
changes in long-term treatment or addition of a new source will provide
an opportunity to minimize any potential impacts on optimal corrosion
control.  EPA has narrowed the scope of this provision in the final rule
to only long-term changes in treatment.  Long-term treatment changes
include the addition of a new treatment process or modification of an
existing treatment process.  Modifications include switching secondary
disinfectants, switching coagulants (e.g., alum to ferric chloride), and
switching corrosion inhibitor products (e.g., orthophosphate to blended
phosphate).  Long-term changes can include dose changes to existing
chemicals if the system is planning long-term changes to its finished
water pH or residual inhibitor concentration.  Long-term treatment
changes would not include chemical dose fluctuations associated with
daily raw water quality changes.

		Alternatives Considered 

		The LCRSTR Workgroup considered various lengths for the time period
before a change that notification had to take place, such as at least 60
days. However, limiting notification to 60 days prior to a treatment
change could be too short for some major changes. Leaving the States
flexibility to decide on a timeframe through a review and approval
process would alleviate such potentially unnecessary burdens.

	

		In addition, some Workgroup members believe that source changes should
be considered in addition to new sources for review and approval. This
may cause additional burden if some States and systems do not consider
source adjustments as new sources. 

3.5 	Regulatory change III.E - Requirement to provide sampling results
to consumers 

		Description of Regulatory Change 

		Systems take tap samples to test for lead for several purposes, most
notably to calculate compliance with the Action Level. The purpose of
this change in rule language is to add the requirement systems provide
consumers (owners and occupants) with the tap monitoring results for
samples taken for routine lead monitoring. The change modifies Sections
141.80(g) and 141.85, and adds a new Section 41.85(e) on the
notification of results. This new section specifies the timing (within
30 days of learning of the results), the content of the notification,
and the method of delivery for the notification.  EPA is also adding a
reporting requirement to §141.90(f) for systems to certify they have
completed this new consumer notification requirement.

		Rationale for Regulatory Change

	Community water systems must collect samples from between 5 and 100
households to calculate the 90th percentile for comparison to the LCR
Action Levels. Non community water systems (including some schools that
operate their own water system) must also collect samples. Currently,
systems are not required to notify the occupants of the lead levels
measured in samples taken from their specific taps. This rule change
would require systems to provide written notification to occupants of
the households within a specified period and to post or otherwise notify
occupants of non- residential buildings of the results of the lead
testing. This would include staff and parents of students for schools
that are tested as non-transient non-community water systems.   SEQ
CHAPTER \h \r 1   SEQ CHAPTER \h \r 1 While these tap samples are
primarily collected to evaluate the effectiveness of corrosion control
or to evaluate the corrosivity of the systems water, the results of the
lead monitoring can provide useful information to the occupants of the
location from which the samples were taken. In addition to the sample
results, the notifications will include an explanation of potential
health risks associated with lead in drinking water, methods for
reducing risks, contact information for the utility, and the 90th
percentile lead level for the most recently completed compliance
monitoring period reported to the State. Occupants may use this
information to inform any decisions they might make regarding taking
actions to reduce their lead exposure.

		Alternatives Considered 

		The Workgroup considered alternative time frames and including the
results of any testing the utility performs in homes and buildings other
than routine monitoring requirements. 

3.6 	Regulatory change III.F – Public education requirements 

		Description of Regulatory Change 

	The purpose of this regulatory change is to modify the public education
requirements of the Lead and Copper Rule (LCR) in the Code of Federal
Regulations §141.85. Water systems would still be required to deliver
public education materials after a lead Action Level exceedance.
However, the content of the message to be provided to consumers, how the
materials are delivered, and the timeframe for delivery will be
modified. The changes to the delivery requirements include additional
organizations that systems must partner with to disseminate the message
to at-risk populations as well as changes to the media used to
disseminate information to ensure water systems reach consumers when
there is an Action Level exceedance. EPA has also added a requirement
for systems to prepare and submit to States and letter certifying that
the public education activities after an Action Level exceedance have
taken place.  Specific changes include the following.

Changes to the mandatory text to written materials

The regulatory change requires systems that have a lead Action Level
exceedance to continue to deliver written materials to all customers as
well as a number of key organizations. However, the content of the
required written materials is modified to be much shorter and easier to
understand. The mandatory language addresses essential topics such as
the opening statement and health effects language. Community Water
Systems and Non- Transient Non-Community Water Systems are still
required to provide information on other topics, but the system may
either use EPA’s suggested language or their own words to explain
these topics. 

Changes to better reach at-risk populations

This regulatory change adds organizations to the list of recipients of
the public education materials in order to increase the likelihood that
the most vulnerable populations or their caregivers will receive the
information they need to reduce their exposure to lead in drinking
water. This includes requiring the system to send information to
licensed childcare centers, preschools and Obstetricians-Gynecologists
and Midwives. In addition, systems are required to include an
informational notice with the printed materials that they send to these
organizations to explain the importance of sharing this information with
their customers/patients. Also, systems are required to directly contact
(e.g., phone, in person, etc.) the local health agency rather than
simply delivering brochures to this organization. By directly contacting
the local health agency, utilities can request the health agency’s
support in disseminating information on lead in drinking water and the
steps that vulnerable populations can take to reduce their exposure.

Systems are also required to complete additional activities from a list
of options. The list of additional activities that systems can choose
from includes the following. 

Public Service Announcements

Paid advertisements such as newspaper or transit ads

Information displays in public areas such as grocery stores

Using the internet or email to disseminate information

Public meetings

Delivery to every household (not just bill paying customers)

Individual contact with customers such as door hangers

Provide materials directly to multi-family homes and institutions

Other methods approved by the primacy agency  

Systems serving more than 3,300 people must implement three additional
public education activities from the list and systems serving 3,300 or
fewer individuals must implement one additional activity. The system
must work in consultation with the State to ensure that the content of
each of these additional activities is appropriate. A system can choose
three items from one, two, or three of these general categories. For
instance, a system can do a series of paid advertisements if that is the
most effective way to reach the target populations in their community.

Changes to help systems maintain communication with consumers throughout
the exceedance

Under this change, systems include information in or on the water bill
no less than quarterly as long as there is an exceedance of the lead
Action Level, with a provision to allow systems to work with their
primacy agency to deliver this information in a different way if
necessary. In addition, systems with a population greater than 100,000
are required to put the public education information on their Web site
until the system tests below the lead Action Level.

Currently, systems that exceed the lead Action Level must issue a press
release. The regulatory change requires that systems distribute two
press releases per year in order to ensure systems are maintaining
communication with their customers. The systems must send the press
releases to the major newspapers and TV and radio stations which cover
the population served by the water system. States can waive the press
release requirement if there are no media outlets that cover the
population served by the system. In addition, the requirement for medium
and large systems to provide two Public Service Announcements (PSAs) per
year is removed. 

Changes to the required timing of completion of public education
requirements

While the revision requires systems to complete public education
activities within 60 days of the end of the monitoring period in which
the exceedance occurred, there is flexibility for the State to allow
longer for completion of these activities.  However, systems must
request and gain State approval on a case-by-case basis for extending
this deadline within the 60-day window. This ensures that the system and
the State begin public education actions to reduce exposure as soon as
possible, but allows these actions to continue past the 60-day timeframe
as needed for effective implementation.

Changes to Consumer Confidence Reports

		The regulatory change will require all community water systems include
information about the risks of lead in drinking water in their Consumer
Confidence Reports on a regular basis. 

		Rationale for Regulatory Change

The intention of changing the public education requirements of the LCR
is to improve compliance and ensure that consumers receive the
information they need to limit their exposure to lead in drinking water.
Because the sources of lead are frequently within the home and reduction
of lead in drinking water is the responsibility of both the public water
systems and the consumer, EPA wants to ensure that information is
delivered and that it is meaningful and useful to the consumer. 

As part of the review of LCR compliance issues, it was determined that
many water utilities did not conduct the required public education,
therefore the at-risk population did not get information they needed to
reduce their exposure from lead in drinking water. EPA believes these
changes better ensure at-risk populations receive information quickly
and are able to act to reduce their exposure. EPA also believes water
systems will be better able to comply with today’s requirements.

During EPA’s national review of the LCR, many stakeholders stated that
the public education requirements needed improvement. In September 2004,
EPA held an expert workshop to discuss the public education requirements
of the rule. A number of concerns were raised at this workshop about the
effectiveness of the existing public education language and
requirements. Workshop participants stated that the mandatory language
in the rule is too long, cumbersome, and complex to convey to the
general public an understanding of the risk posed by lead in drinking
water and an appropriate course of action. Public education must put the
risk in context and convey to the public the appropriate sense of
urgency for consumers to act to reduce exposure. In addition, workshop
members called for public education messages to be tailored to those who
are at highest risk for lead exposure. Many participants stated that the
mandatory language and delivery requirements in the current rule were
ineffective in providing useful and timely information to the public. 

In order to address these concerns, the National Drinking Water Advisory
Council (NDWAC), EPA’s advisory body on the Safe Drinking Water Act,
formed a working group to consider possible revisions to the public
education requirements. The NDWAC Working Group raised a number of
concerns with the public education requirements of the LCR that are
consistent with the concerns expressed at the 2004 workshop. The NDWAC
Working Group recommended that the rule be modified to better ensure
that information reaches the most vulnerable populations (e.g., pregnant
women, infants and young children) or their caregivers. They also
recommended changes to ensure that these consumers received information
in a more timely manner and continued to receive information throughout
any exceedance. They also recommended changes to ensure that the
information is easy to understand and effective in informing affected
consumers and encouraging parents or other caregivers to take actions to
reduce exposure of infants and children to lead. In addition, the NDWAC
Working Group recommended changes to make sure critical information
reaches not only bill paying customers, but those consumers who live in
apartments and other housing where residents do not receive bills. 

Finally, the NDWAC Working group was also concerned about the amount of
time it may take to test water, get back the results, calculate the 90th
percentile, and finally send out public education materials. They were
concerned that an individual could be drinking water with high lead
levels for months before knowing of the problem. As a result, they
recommended changes to increase the timeliness of public education on
lead in drinking water.

		The NDWAC recommendations are, in part, modeled after the public
education information under two existing EPA rules, the CCR and the
Public Notification Rule (40 CFR 141, Subpart Q). The NDWAC
recommendations form the basis for the changes to § 141.85 in this
rulemaking.

		Alternatives Considered 

	The NDWAC Working Group considered many alternatives during their
deliberations in the areas of mandatory language, delivery requirements
to make the public education program more effective, consultation
between systems and States, the timing of notification, and means for
targeting vulnerable populations.

3.7 	Regulatory change III.G - Reevaluation of Lead Service Lines
deemed replaced. 

		Description of Regulatory Change 

		Under the existing rule, systems that are replacing lead service lines
in response to an Action Level exceedance may sample lead levels from
lead lines. If the sampled lead levels from an individual service lines
is below the Action Level (15 ppb), that line would not have to be
physically replaced, but could be considered replaced towards meeting
the goal of 7 percent replacement. Since these “tested-out” lines
are considered replaced, they do not have to be re-evaluated if water
quality conditions or treatments change.

		The rule language requires that these “tested-out” lines be
re-evaluated if a system subsequently exceeds the Action Level and is
triggered back into further lead service line replacements. The
tested-out lines are put back into the inventory of lead service lines
and are then treated as any other line in the inventory, to be either
re-tested and “tested-out” or re-tested and replaced if the lead
levels for the line exceed the Action Level.

		Rationale for Regulatory Change

	This “test-out” provision was intended for service lines that are
not leaching high levels of lead. However, if a system has again
exceeded the Action Level, the previous service line sample may no
longer be representative of the lead concentrations being contributed by
the service line under the new conditions causing the Action Level
exceedance. For example, in the recent case of elevated lead levels in
the DC WASA system, the switch from chlorine to chloramines may have
changed the corrosiveness of the water in the distribution system,
potentially elevating lead levels, especially those from the service
lines. Service line samples collected under chlorination may not be
representative of service line samples under chloramination. Re-testing
is necessary to determine whether these lines are still contributing low
levels of lead under the new conditions. If not, then the line should be
considered for replacement along with the rest of the inventory of lead
service lines.

		Alternatives Considered 

		The workgroup did not consider any alternatives to this rule change.

4	Costs of Regulatory Changes

		This chapter describes the estimates of costs for the regulatory
changes to systems and State Primacy Agencies (States), including costs
associated with administrative, monitoring, sampling, reporting, and
public notification activities. There are two types of costs that may
result from the regulatory changes – direct and indirect. Direct costs
are costs for activities that are specified by the regulatory change,
such as costs for additional monitoring or distribution of consumer
notices. Indirect costs may also result when systems and States use the
information generated by the directly–related rule activities to
modify or enhance practices to reduce lead levels. These indirect costs,
and related health risk reductions, are not quantified for the purposes
of this analysis, but are described qualitatively in greater detail in
Section 5 of this document. The remainder of Section 4 focuses solely on
the estimation of direct costs. Exhibit 4 summarizes the expected direct
and indirect cost impacts for the seven regulatory changes.

Exhibit 4: Summary of Direct and Indirect Implications of the LCR Short
Term Regulatory Changes

Rule Change #	Rule Change Description	Direct Cost Implications	Indirect
Cost and Health Risk Implications

III.A	Number of samples	Yes	Yes

III.B	Monitoring period	Unquantified	None

III.C	Reduced monitoring criteria	Yes	Yes

III.D	Advanced notification and approval 	Yes	Yes

III.E	Consumer notice of Lead results	Yes	Yes

III.F	Public Education	Yes	Yes

III.G	Reconsideration of lead service lines	Yes	Yes



		The costs associated with the Lead and Copper Rule have been estimated
previously in several documents. Direct costs due to the 1991 Lead and
Copper Rule are presented in the Final Regulatory Impact Analysis of
National Primary Drinking Water Regulations for Lead and Copper, April
1991. This RIA estimates costs for monitoring, coping with source water
contamination, coping with lead leached from solder, coping with lead
leached from lead service lines (including public education, corrosion
control, and lead service line replacement), and State implementation
costs.

		EPA proposed and adopted minor changes to the LCR. The direct costs
for these minor changes are described in Regulatory Impact Analysis
Addendum: Proposed Changes to National Primary Drinking Water
Regulations for Lead and Copper, January 1996. This addendum estimates
changes to costs with respect to the April 1991 RIA, under the same cost
categories. An Information Collection Request was also prepared for the
minor rule changes, Information Collection Request: National Primary
Drinking Water Regulations For Lead and Copper, June 1999.

		The most recent cost estimates can found in the 2004 Information
Collection Request for Disinfectants/Disinfection Byproducts, Chemical,
and Radionuclides Rules, OMB Control Number: 2040-0204, EPA Tracking
Number: 1896.05. The 2004 ICR estimates administrative burden and costs
associated with the LCR for systems and States. Direct system costs are
estimated for community water systems and non-transient non-community
water systems to perform the following activities:

Conduct monitoring for water quality parameters 

Conduct tap sampling of lead levels for Action Level compliance

Review sample data, including the calculation of lead and copper 90th
percentile levels

Submit monitoring data and any other documents or reports to the State

Record and maintain information

The 2004 ICR also estimates burden and costs for systems that must
submit corrosion control studies, recommend and submit information
regarding the completion of corrosion control or source water treatment
installation, conduct public education, or conduct LSL monitoring,
notification, and replacement.

	In the 2004 ICR, for the LCR requirements to CWSs and NTNCWSs, the
average annual respondent burden is estimated at 1.72 million hours and
$57.9 million for reporting (including lead service line replacement
reporting), recordkeeping, and public education activities of the LCR.
For States, the annual burden incurred by primacy agencies for
activities associated with the lead and copper regulation is
approximately 0.21 million hours and $6.8 million. This estimate
includes costs for employing a corrosion control expert and costs to
review various letters and results submitted by water systems in
accordance with the LCR.

4.1		Overall Cost Methodologies and Assumptions

		

		As part of its comprehensive review of the Lead and Copper Rule, EPA
collected and analyzed new data on various aspects of LCR
implementation. When available, this new information is the first choice
source for use in estimating costs. Sources of the new information
include the following.

Medium and Large Public Water Systems Exceeding the Action Level Summary
from SDWIS/FED data as of January 27, 2005 provides up-to-date counts of
the number of medium and large systems that have exceeded the Action
Level since 2000 and 2003.

Summary, Lead Action Level exceedances for public water systems subject
to the Lead and Copper Rule (For data through September 13, 2004)
provides up-to-date counts of the number of small systems that have
exceeded the Action Level since 2000 and 2003.

State responses to EPA’s “ Survey of States Questions on State
Implementation of the Lead and Copper Rule” (July 2004) provides
information on the number of systems that are conducting lead service
line replacement under the LCR, the fraction of systems on reduced LCR
monitoring, and system practices with regard to notification of
customers of sampling results.

		If new information was not available about a cost item or assumption,
previous analyses of LCR requirements were reviewed to determine if a
suitable estimate was available. The 1991 RIA, the 1996 RIA Addendum,
and the various Information Collection Requests were all used as sources
of information and assumptions.

		In a limited number of instances, appropriate estimates were not
available either from new analyses or existing documents. For those cost
items, the best professional judgment used to derive estimates.

		For the regulatory changes that clarify rule language (III.B), the
costs associated with those activities may have already been included in
the original LCR cost estimates as presented in the 1991 RIA. In these
cases, costs for performing these activities are not included in this
analysis.

		Inventory of Systems

		The primary inventory of systems that will be impacted by the direct
costs of the regulatory changes was derived from a pull of data from the
SDWIS/FED system in the 4th quarter of 2004, available at   HYPERLINK
"http://www.epa.gov/safewater/data/pivottables.html" 
http://www.epa.gov/safewater/data/pivottables.html  and summarized in
FACTOIDS: Drinking Water and Ground Water Statistics for 2004.  The
number of systems covered by the LCR that result from the SDWIS/FED pull
for 2004 are summarized in Exhibit 5.

		Wage Rates

		Wage rates for systems were taken from the report Labor Costs for
National Drinking Water Rules prepared by Science Applications
International Corporation (SAIC) in October 2003 for EPA’s Office of
Ground Water and Drinking Water. Exhibits 20 and 21 of that report
summarize recommended average technical and managerial wage rates by
system size for EPA to use in cost analyses. These rates are updated to
4th quarter 2006 levels using the Employment Cost Index.  To represent
the composition of staff at PWSs of smaller sizes (e.g., systems serving
fewer than3,300 people), EPA uses only the updated technical rate. For
systems serving 3,300 or more people, EPA uses a ratio of 80 percent
technical labor to 20 percent managerial labor to arrive at a weighted
labor rate.  Appendix B presents the wage rates for systems used in the
cost analyses.

		Wage rates for States are based on information provided by the
Association of State Drinking Water Administrators (ASDWA) as presented
in the Information Collection Request for Contaminant Occurrence Data in
Support of EPA's Second Six Year Review of National Primary Drinking
Water Regulations (August 2006). Please refer to Appendix A for further
detail.

		

		Incremental Direct Costs Quantified

		As discussed earlier, Regulatory Changes III.A, III.C, III.D, III.E,
III.F, and III.G are expected to result in direct costs to States and
systems. For these potential regulatory changes, direct costs could be
incurred in the areas of system reporting, tap water monitoring and
public education for systems, and review and consultation for
States/Primacy Agencies. Exhibit 6 summarizes the direct cost categories
to be estimated for each regulatory change. The following sections
present either the rationale for why direct costs are not incurred, or
estimate of direct costs for each rule provision.

4.2 	Direct Costs Associated with Regulatory Change III.A 

		Activities resulting from regulatory change

		Regulatory change III.A clarifies EPA’s intent that a minimum of 5
tap samples must be taken when conducting LCR compliance monitoring. If
a system has fewer than the minimum number of sites required for
sampling, then those systems will have to collect multiple samples on
different days from the same site so that the total number of samples
per monitoring period is 5. However, III.A gives States the discretion
to allow certain systems with fewer than 5 taps on a case by case basis
to take 1 sample per tap.  Under this alternate sampling schedule, the
sample with the highest test result will be compared to the action level
to determine compliance.  

		Public water systems with fewer than 5 taps that are in States that
allow 1 sample per tap will undertake a one time activity to document
the number of appropriate taps and communicate this information with the
State.  States that will allow 1 sample per tap will engage in a one
time effort to review, track, and respond to submittals from the systems
with fewer than 5 taps on the number of appropriate taps for future
sampling.

	Costs to systems 

	The systems that will incur costs under this regulatory change are
NTNCWSs and CWSs with fewer than 5 taps in States that allow 1 sample
per tap. The following data are used to estimate the number of systems
impacted by the regulatory change and related direct costs.

The number of NTNCWSs in States that will allow 1 sample per tap:  This
analysis assumes that the 11 States that commented favorably on the
option of allowing 1 sample per tap for NTNCWSs with fewer than 5 taps
will exercise their discretion under III.A and permit 1 sample per tap. 
Note that two States commented unfavorably on the option and it is
assumed States that did not comment at all would not allow the
alternative since the default requirement maintains a minimum of five
samples.  Exhibit 7 contains estimates of the number of NTNCWSs in these
11 States.

The number of CWSs with fewer than five taps in States that will allow 1
sample per tap:  This analysis assumes that the 11 States that commented
favorably on the option of NTNCWSs will also allow permit 1 sample per
tap for applicable CWSs.  In addition, the analysis assumes that Alaska
will exercise its discretion to allow 1 sample per tap for small CWSs
due to the presence of washeterias in the State.  This analysis assumes
that all CWSs with fewer than five taps are a portion of those that
serve 100 or fewer people since EPA believes that CWSs with fewer than 5
taps, even in the smallest system size category, are relatively unique
situations and do not occur frequently. Exhibit 7 contains estimates of
the number of CWSs serving 100 or fewer people in the 11 States plus
Alaska.

Source: SDWIS/FED data pull from the 4th quarter of 2004.

The fraction of NTNCWSs that have fewer than 5 taps:  No nationally
available data source provides information on the fraction of NTNCWSs
with fewer than 5 taps.  However, in their comments submitted on the
Draft LCRSTR, MI provided information that 53% of the NTNCWSs in MI had
fewer than 5 taps.  In the absence of other data, this analysis assumes
that 53% of the NTNCWSs in the 11 States have fewer than 5 taps. 
Exhibit 8 displays the calculation of the number of NTNCWSs with fewer
than 5 taps in the 11 States.

The fraction of CWSs serving <101 people that have fewer than 5 taps: As
stated above, EPA believes that CWSs with fewer than 5 taps, even in the
smallest system size category, are relatively unique situations and do
not occur frequently.  In the absence of any other data source, this
analysis assumes that 5% of CWSs serving <101 have fewer than 5 taps, as
displayed in Exhibit 8.

The labor and cost estimates per applicable system with <5 Taps: Based
on similar activities, it is estimated that systems will take 1 hour to
prepare a letter to States verifying the number of applicable taps for
lead and copper sampling, with a materials cost of $0.43 for postage and
supplies.  This analysis assumes that all systems that are eligible for
taking 1 sample per tap will request this option from States. 

The one-time direct costs to systems, summarized in Exhibit 9, are
estimated to be $104,000 including $102,500 in labor costs and $1,600 in
materials costs. Detailed estimates are provided in Appendix J. 

		Costs to States

Regulatory Change III.A will require State/Primacy agencies that
exercise their discretion and allow 1 sample per tap for applicable
systems with fewer than 5 taps to verify the appropriate number of taps
per system by reviewing the letters submitted by systems and responding
to systems. 

Estimates of state review burden are based on similar activities (such
as reviewing a letter reviewing tap monitoring events).  States are
estimated to take 1 hour to review and respond to the letter from
systems verifying the applicable number of taps for sampling.

The one-time direct costs to State/Primacy agencies is estimated to be
$162,000 ($160,700 in labor costs and $1,600 costs for postage and
supplies to mail the response letter to systems), as summarized in
Exhibit 9. Detailed estimates are included in Appendix J.

4.3 Direct Costs Associated with Regulatory Change III.B

	Regulatory Change III.B clarifies the terms “monitoring period” and
“compliance period.” Based on the regulatory change, if a system
exceeds the lead or copper Action Level during a monitoring period, the
compliance calendar for required actions starts at the end of the
monitoring period, which for most systems would occur on September 30.
Under the previous regulatory language, systems were confused as to
whether compliance actions began at the end of that calendar year
(December 31) rather than the monitoring period (September 30). 

	As a result of the regulatory change, activities triggered by a lead or
copper Action Level exceedance could begin three months earlier (i.e.,
at the end of September instead of the end of December), but it is not
clear if activities would last any longer. The net result is a change in
the timing of activities, with a difference of three months having an
unclear impact on costs, although there may be health risk implications.

 

4.4 	Direct Costs Associated with Regulatory Change III.C

		Activities resulting from regulatory change

As a result of Regulatory Change III.C, utilities that are conducting
LCR compliance monitoring on a reduced monitoring schedule and that have
90th percentile LCR monitoring samples that exceed the lead Action Level
will be required to resume standard monitoring schedules for monitoring
lead at taps. In addition to monitoring activities, utilities will have
to meet reporting requirements to the State/Primacy agency.
State/Primacy agencies will be involved in review of utility monitoring
reports. Supporting calculations and information are included in
Appendix C.

		Costs to systems

	

	The systems that will incur direct costs under this regulatory change
are those systems that exceed the lead Action Level and that had been on
a reduced monitoring schedule. The following data are used to estimate
the number of systems impacted by the regulatory change and related
direct costs.

Number of systems exceeding the lead Action Level:  This analysis uses
the number of systems that have exceeded the lead Action Level since
2003 as an estimate of the number of systems that will exceed the lead
Action Level each year in the near future. Exhibit 10 contains estimates
of the number of systems exceeding the lead Action Level annually by
size category.

1. Data source: USEPA Survey of States - Questions on State
Implementation of Lead and Copper Rule. July 2004.

2. Data Source: www.epa.gov/safewater/lcrmr/lead-data.html, 8/30/05.

Percent of systems on reduced monitoring:  In their responses to the EPA
survey on LCR implementation, States provided estimates of the percent
of systems on reduced LCR monitoring (summarized in Appendix C-1). Based
on this data, 91 percent of systems are on a reduced schedule for LCR
lead and copper monitoring. In the absence of additional data, this
analysis assumes that systems that will exceed the lead Action Level are
on a reduced monitoring schedule at the same rate as all systems.
Therefore, we assume that 91 percent of the systems that exceed the lead
Action Level were on reduced monitoring and will therefore incur direct
costs due to regulatory change III.C. This assumption may be
conservative, because systems that are likely to have exceedances are
less likely to be on reduced monitoring.

Additional monitoring events: The frequency for monitoring on a standard
schedule under the LCR is once every 6 months. Reduced monitoring could
refer to either monitoring once every year or once every three years.
From the state responses to the survey, it is impossible to distinguish
the number of systems on a reduced monitoring schedule of once every
year from those monitoring once every three years. This analysis assumes
that all systems on reduced monitoring are on the triennial schedule, a
conservative assumption that might slightly over-estimate costs. Thus, a
system that was on reduced monitoring but is placed on a standard
monitoring schedule after a lead Action Level exceedance under
regulatory change III.C will incur an additional 5 monitoring events
over a 3 year period (6 monitoring events in three years under standard
monitoring instead of 1 monitoring event in three years under reduced
monitoring).

Tap samples per monitoring event: The number of samples collected in
each monitoring period will also change when the utility switches from
reduced monitoring to standard monitoring. The required number of
samples varies by system size, with the smallest systems (serving less
than or equal to 100 people) required to take 5 samples per monitoring
event under both standard and reduced monitoring, and the largest
systems (serving > 100,000 people) required to take 100 samples per
monitoring event under standard monitoring, and 50 samples per
monitoring event under reduced monitoring.

Labor and cost estimates per sample: Based on previous EPA documents,
the labor required to collect each lead and copper compliance tap sample
is estimated at 2.5 hours. The labor to analyze the sample for lead and
copper is estimated at 1 hour, with a material cost of $8.16 per sample
(also referred to as the materials cost). In addition, systems must
calculate their 90th percentile value to assess compliance and report
the monitoring and compliance results to the State. These activities are
estimated to require 1.5 to 2 hours per system, varying by system size,
with a materials cost of $0.39 for postage and $0.04 in materials. The
derivation of the labor and cost estimates relating to compliance
monitoring is detailed in Appendix C-2.

The direct Costs to systems, summarized in Exhibit 11, are estimated to
be $2,696,000 annually including $2,502,000 in labor costs and $194,000
in materials costs. Detailed estimates are provided in Appendices C-4
and C-5. 

		Costs to States

Regulatory Change III.C will require State/Primacy agencies to review
utility monitoring reports as a result of resuming standard monitoring
schedules. 

Estimates of state review burden are based on the 2004 ICR page H-12,
which estimates that a State takes 1 hour to review the letter
describing a tap monitoring event for each system. Additionally, States
will spend an additional 10 minutes to 1 hour checking the compliance
(90th percentile) calculations for each monitoring event. The materials
cost is limited to postage for letters sent to utilities regarding
review findings.

The direct costs to State/Primacy agencies is estimated to be $82,000
annually including $81,000 in labor costs and $1,000 in materials costs,
as summarized in Exhibit 11. Detailed estimates are included in Appendix
C-7.

4.5 	Direct Costs Associated with Regulatory Change III.D

		Activities resulting from regulatory change

	Regulatory Change III.D revises the current 60-day notification
requirement, under which systems notify States about long-term changes
in treatment or additions of new sources that could cause problems with
optimal corrosion control. Rather than requiring systems to notify
States up to 60 days after treatment changes or source additions have
been made, systems now must notify the states in advance and the changes
must undergo a formal review and approval process by the State prior to
implementation. All States currently review treatment or source changes
within 60 days after the change.  However, some States are already
reviewing and issuing approval before such changes are made. The
activities associated with the formal review and approval process are a
new requirement for those States that do not currently have such a
review and approval process. System activities will include preparation
of a submittal to the State and coordination with the State/Primacy
agency during the review. State/Primacy agency activities will include
review of system data/reports and coordination with systems. 

		Costs to systems

	In order to estimate the cost of this provision to utilities,
information is needed on the number of systems that will change a
treatment or add a source annually, as well as the number of systems
that are located in States that already have a review and approval
requirement. Systems located in these States will not incur additional
costs under this provision.

States with review and approval process:  Many States already have a
review and approval process for treatment or source changes. As part of
the survey on LCR implementation, EPA asked States to respond to the
following question:  “How do systems notify the State of treatment
changes?  Does the State require that systems provide information about
potential effects of treatment changes on corrosion control?”  A
summary of State responses is provided in Appendix D-1. Based on the
State responses, 14 States explicitly replied that they currently have a
review and approval process for treatment changes. It should be noted
that another nine States mention a process that requires a permit for
treatment changes and eight States refer to submittal and review of
engineering plans for a change. Although not a review and approval
process focused specifically on the impact of a change on corrosion
control, the permitting and plan review processes may be comprehensive
enough that they consider corrosion issues. For the purposes of this
analysis, however, we base our estimates by excluding only the 14 States
that specifically consider corrosion issues, recognizing that other
States may also include corrosion issues in their review processes.

Number of systems in States without an existing review and approval
process:  Based on the characterization of the process for each State
and the number of systems in each State, the number of systems that are
not covered by an existing process and may therefore incur costs under
this regulatory change is estimated in Appendix D-1. Under the
alternative in which only the 14 States with explicit review and
approval are excluded from the count, 53,372 systems (of 72,213 CWSs and
NTNCWSs) may incur costs for the regulatory change. 

Fraction of systems that change treatment or add a source each year:
Treatment changes over the next several years are likely, as systems
will be faced with new regulatory requirements, including changes to
comply with the already promulgated Arsenic Rule and the upcoming Long
Term 2 Surface Water Treatment Rule and Stage 2
Disinfectants/Disinfection Byproducts Rule. Together, these regulatory
requirements are estimated to cause 9,243 systems to institute a
treatment change, although not all of these treatment changes will
affect corrosion control. Also the compliance periods for these
regulations varies. To account for these expected treatment changes, and
to account for treatment changes and source additions unrelated to the
Arsenic, LT2, and Stage 2 rules, EPA assumed (based on the projected
rule-related treatment changes and expert judgment) that approximately
20% of the systems affected by the LCR will institute a treatment change
in the next ten years. It is assumed that these changes occur uniformly
over that 10-year period, so that approximately one-tenth of these
systems (or 2 percent of the total) institute a treatment change or
source addition each year. Appendix D-2 provides additional detail.

Based on the 2 percent assumption, the analysis estimates that 1,067
(53,372 X .02) systems each year would report a treatment change or
source addition and incur costs in States currently not covered by an
explicit review and approval program.

 

System burden and activities: EPA anticipates that systems will incur
additional costs under this rule change as systems and States more
carefully review and consider possible corrosion impacts of treatment
changes or source additions. The activities and burden associated with
the review and approval process are expected to vary based on the size
and complexity of a system, and the nature of the change or source
addition. In the absence of information on the current prevalence of
these activities, EPA has used the best professional judgment to
estimate the range of potential activities and associated costs
resulting from the review and approval process. All systems, regardless
of size or complexity, are assumed to undertake additional activities
related to data collection and evaluation, preparation of a submittal to
the State, and coordination with the State. For small systems or systems
making relatively simple changes, considering the corrosion impacts of
the change may be a rather basic process of reviewing water quality data
and previous lead monitoring results. For these systems, additional
effort will be incurred by system staff in coordination with State
personnel to assemble water quality parameter and lead data and evaluate
the potential impacts.  EPA estimates the burden for this additional
effort at 7.5 hours per system, at an average cost of $231 per system. 
For larger or more complex systems making major treatment changes,
activities would be more extensive, including conducting engineering
studies to evaluate impacts on corrosion control. To some extent,
systems may already be conducting these studies, resulting in no net
cost due to the regulatory change.

The current LCR regulatory requirements on notification of treatment
changes cause a system burden of 0.5 hours per treatment change.
Therefore, the new system burden is expected to be 8 minus 0.5 hours or
7.5 hours per treatment change.   

Additional burden for engineering studies:  Based on best professional
judgment, EPA estimates that between 10 percent and 20 percent of medium
and large systems may incur the additional cost of $20,000 to conduct an
engineering study on corrosion impacts. The $20,000 estimate is based on
recent similar studies for medium-sized systems.

The direct costs to systems are estimated to range from $506,000 to
$765,000 annually. These direct costs are strictly labor costs; material
costs are expected to be negligible. Detailed estimates are provided in
Appendix D-3. 

		Costs to States

Those States that do not already have a review and approval process will
also incur additional costs due to regulatory change III.D. 

Activities that States will undertake include review of system data,
preparation of conclusions and letter to systems, and coordination with
utilities. The level of effort associated with these activities is
expected to vary based on the complexity of the change and the type of
submittal (amount and type of information). Based on best professional
judgment, State review could range from 4 hours to 8 hours.

The current LCR regulatory requirements on State review of treatment
changes entail a burden of 0.5 hours per review. Therefore, the new
State burden is expected to range from 3.5 to 7.5 hours per treatment
change. 

Based on the State responses on existing review and approval processes,
the analysis assumes that 14 States have existing processes (explicit
review and approval). The remaining States will incur costs under this
regulatory change.

The direct costs to State/Primacy agencies are estimated to range from
$163,000 to $348,000 annually. These direct costs are strictly labor
costs; material costs are expected to be negligible. Estimates are
summarized in Exhibit 9 and detailed in Appendix D-4.

 4.6 	Direct Costs Associated with Regulatory Change III.E

		Activities resulting from regulatory change

		Regulatory Change III.E will require systems to provide written
notification to each owner/occupant of the lead level found in the tap
sample collected for LCR compliance monitoring. Both CWSs and NTNCWSs
are required to provide notification on tap sampling results, but the
activities are expected to differ between the two types of systems. In
addition, systems are required to certify to States in a letter that the
notification activity has taken place.  Supporting calculations and
information regarding Costs to systems associated with this regulatory
change are included in Appendix E. 

		Costs to systems

		In order to estimate the additional direct costs associated with
regulatory change III.E, information is needed on the number of systems
that already notify customers of tap monitoring results and the burden
associated with notification activities.

Number of systems that already notify customers:  Based on feedback from
participants in workshops and interactions with States, some systems
already notify customers of monitoring results for their particular
establishments. These systems would not incur costs under the regulatory
change. This analysis uses information from the State survey to develop
an estimate of the number of systems that currently notify customers of
tap sampling results, as detailed in Appendix E-1. Of 72,213 CWS and
NTNCWSs (per 2004 SDWIS/Fed data) subject to the LCR, approximately 11
percent of these systems are estimated to already notify owner/occupants
as derived from USEPA’s Survey of States (July 2004). Therefore, this
regulatory change will apply to the remaining 89 percent of systems or
64,273 systems. 

Activities associated with notification: CWSs will prepare a customer
notification letter and mail letters to all owner/occupants for
residences where tap samples were collected. For NTNCWSs, the
notification burden will be different, and may consist of posting a
notice on community bulletin boards or web sites.

Activities associated with reporting to States:  CWSs and NTNCWSs will
prepare a letter to the State certifying that they have completed the
required notification activities. 

Burden and costs for CWSs: Labor costs are based on the labor required
to prepare a sample customer notification letter and mail letters to
customers. The system burden is estimated to be 1 hour per monitoring
event for systems serving <3,300 people and 1 hour per 20 sample letters
for systems serving more than 3,300 people. For example, systems serving
less than 3,300 people will prepare either 5 or 10 customer letters for
each monitoring event at an estimated time burden of 1 hour. Material
costs include paper, envelopes and postage, estimated at $0.43 per
customer letter.

Burden and costs for NTNCWSs:  Costs for NTNCWSs include the labor
required to prepare a consumer notice and post the notice. It is
estimated that all systems will spend 1 hour per monitoring event. It is
assumed that material costs are negligible for NTNCWSs.

Burden and costs for reporting:  Both CWSs and NTNCWSs will incur labor
to prepare a self-certification letter and submit the letter to the
State.  Based on a similar activity under the CCR, the labor to prepare
the self-certification letter is estimated at .12 hours per system (PWSS
ICR, 2040-0090, page B-5), with materials cost of $0.43 for postage and
supplies.

Frequency of monitoring and number of samples: Of the 64,273 systems
affected by this Regulatory Change, it is assumed that 91 percent of
systems are currently on a reduced monitoring schedule, and 9 percent
follow a standard monitoring schedule as documented in USEPA’s Survey
of States (July 2004). Although reduced monitoring can imply a 1 year, 3
year or 9 year monitoring frequency, a 3 year frequency is assumed for
all systems for use in this economic analysis. The number of samples
collected by each system is estimated based on sampling schedules
established in 40 CFR 141.86c for standard and reduced monitoring
according to population served. In addition, the number of increased
monitoring events that would result from Regulatory Change #III.C (1,692
additional monitoring events per year) are added to the total. 

		The direct costs to systems for compliance with Regulatory Change
#III.E are summarized in Exhibit 13 and estimated to be $1,248,000
annually including $1,098,000 in labor costs and $150,000 in material
costs. Detailed estimates are provided in Appendix E.

	

		Costs to States

		States will incur costs to review and track the self-certification
letters from systems.  Based on a similar activity for the CCR, this
analysis estimates that States will require 0.10 hours per system letter
(PWSS ICR, 2040-0090, page B-7).  The direct costs to States for review
under Regulatory Change #III.E are summarized in Exhibit 13 and
estimated to be $163,000 annually (all labor costs). Detailed estimates
are provided in Appendix E.

4.7		Direct Costs Associated with Regulatory Change III.F

	 (a) Changes to the mandatory text of the written materials

	(a)(1) Customer Notification

		Activities resulting from regulatory change

	Regulatory change III.F(a)(1) substantially reduces the mandatory
language required for delivery to all bill paying customers after a lead
Action Level exceedance and gives systems more flexibility in developing
the notification. Systems are required to address several topics in the
notification, namely: “sources of lead”, “steps to reduce
exposure”, “what happened”, and “what is being done”. This
analysis assumed that template language will be provided for the sources
of lead and steps to reduce exposure sections. However, by their nature,
the “what happened” and “what is being done” sections will need
to be customized by each system to reflect their specific conditions.
Therefore, the additional activity under this change is the effort
required to develop the sections specific to the system.

Costs to systems

	In order to estimate the additional direct costs associated with
regulatory change III.F(a)(1), information is needed on the number of
community water systems that exceed the lead Action Level and the burden
associated with language development activities.

Number of systems exceeding the lead Action Level:  This analysis uses
the number of water systems that have exceeded the lead Action Level
since 2003 as an estimate of the number of systems that will exceed the
lead Action Level each year in the near future. Exhibit 14 contains
estimates of the number of community and non-community systems exceeding
the lead Action Level annually by size category.

2. Data Source: www.epa.gov/safewater/lcrmr/lead-data.html, 8/30/05.

Burden to prepare system specific notification language: Because the
current notification after an Action Level exceedance relies solely on
mandatory language, the 2004 ICR does not provide a burden effort for a
similar activity. However, the ICR for the Public Notification Rule
(PNR) includes a burden estimate associated with a Tier 2 notification
(notice as soon as possible of an exceedance that does not pose an
immediate health threat). The 3.5 hours of labor per system will be used
to estimate the additional burden associated with developing the new
language after an Action Level exceedance.

	The direct costs to systems for compliance with Regulatory Change
#III.F(a)(1) are summarized in Exhibit 15 and estimated to be $91,400
annually, all in labor costs. Detailed estimates are provided in
Appendix H-2.

(b) Changes to better reach at-risk populations

 (b)(1) Delivery of brochures to organizations

		Activities resulting from regulatory change

Regulatory change III.F(b)(1) requires that CWSs exceeding the lead
Action Level distribute brochures to three additional types of
organizations – obstetric/gynecologist offices, licensed child care
facilities, and pre-schools. Also, an informational notice must now be
included with the brochures and the public health agency must be
directly contacted by phone, rather than through a mailed brochure. 

Costs to systems

	In order to estimate the additional direct costs associated with
regulatory change III.F(b)(1), information is needed on the number of
community water systems that exceed the lead Action Level, the number of
additional organizations to be contacted, and the burden associated with
distributing brochures to the additional organizations, the development
of an informational notice, and the direct contact with the public
health agency.

Number of community systems exceeding the lead Action Level:  The number
of CWSs that exceed the lead Action Level can be found in Exhibit 11.

Number of additional organizations to be contacted: The number of
additional establishments to be contacted is estimated at 193 per
100,000 population served. This value includes 178 per 100,000 licensed
child day care facilities based on the number of licensed child day care
facilities (500,143) spread over the national population (281,422,000).
The total also includes 15 ob/gyns per 100,000 population (41,900 
ob/gyns per 281,422,000).

Burden to contact additional organizations: Systems serving greater than
3,300 will incur an additional 1 hour in burden to generate and update
lists of additional facilities. These systems will also incur production
costs of 0.25 hours for every 100 additional brochures and applicable
mailing and materials costs.

Burden to develop informational notice:  Based on similar activities,
this analysis assumes that developing an informational notice for
distribution with the brochures will take a system 1 hour.

Burden to directly contact public health agency:  Based on similar
activities, this analysis assumes that directly contacting the public
health agency through a telephone call will require an additional 0.5
hours.

The direct costs to systems for compliance with Regulatory Change
#III.F(b)(1) are summarized in Exhibit 16 and estimated to be $43,300
annually, in labor costs and material costs. Detailed estimates are
provided in Appendices H-3 through H-5.

(b)(2) Additional activities

		Activities resulting from regulatory change

	Regulatory change III.F(b)(2) requires systems to perform additional
public notification activities. Systems are given a choice of 8
activities. Systems serving fewer than 3,300 must implement 1 activity
from the list while other systems must implement 3 activities.

Costs to systems

	In order to estimate the direct costs for regulatory change
III.F(b)(2), the cost for each of the activities per system needs to
estimated. Exhibit 17 contains a summary of the assumptions used to
derive the cost per system for the eight activities. Detailed
calculations can be found in Appendices H-6 through H-20. Exhibit 18
summarizes the resulting costs per system.



Exhibit 17: Assumptions Used to Derive System Costs for III.F(b)(2)

III.F(b)(2)(i) Public Service Announcements

	Production of a radio PSA involves developing a script for the spot and
then producing an audio of the spot. 

For small systems (serving fewer than 10,000) assume produce 1 radio PSA
using freelance voice talent and in-house staff to prepare the content
of the PSA. Assume $50 for the voice-over, based on internet quotes from
free-lance talent and 2 hours for the system to develop the contents.
Total cost per radio PSA: $95.

For systems serving greater than 10,000, assume produce 1 radio PSA and
1 TV PSA. 

For a large system to produce a radio PSA, assume they use union talent
at a studio. Based on internet quotes, union talent is about $280 per
hour plus $80 per hour for studio time. Also assume that a large system
uses a freelance writer to develop the script at $200 for 2-3 hours of
effort. Total cost for radio PSA: $560.

For a large system to produce a TV PSA, assume on-camera talent at about
$560 per hour, plus studio time (based on internet quotes) and script
development. Total cost for TV PSA: $840.

III.F(b)(2)(ii) Paid Advertisements

	Assume 1 newspaper advertisement, 10 column inches (about 1/8 of a
page), rates derived from internet research.

Rate per 10 column inch advertisement for system >1,000,000: $5,000

Rate per 10 column inch advertisement for system 50k to 1 mil: $850

Rate per 10 column inch advertisement for system 3.3k to 50k: $180

Rate per 10 column inch advertisement for system <3.3k: $105

III.F(b)2(iii) Display Information in Public Areas

	Assumed to involve posting a notice at local grocery stores or other
locations. Posting would be free, but costs incurred to travel to
identify and travel to establishments, plus materials cost. 

Assume 1 hour to do 5 postings.  Number of postings varies by system
size.

III.F(b)(2)(iv) Internet Notification

	Assumed to entail email contact with all customers. 

Requires time to develop email and review contact list.  Time varies by
system size.

Assume small systems have an email list.  Large and medium systems must
purchase list.

III.F(b)(2)(v) Public Meetings

	For systems serving fewer than 3,300, assume that system reps would
bring up the issue for discussion at an existing town meeting. Assume 2
hours preparation and meeting time.

For systems serving over 3,300, assume conduct of separate public
meeting of 2.5 hours. Effort includes making logistical arrangements,
preparing 30 – 45 minute presentation, attending the meeting, and
follow-up activities.

III.F(b)(2)(vi) Delivery to Every Household

	Delivery to every postal address, either through mail or distribution
of flyers. Based on internet quotes for distribution of flyers: $.12 to
$.25 per piece, based on volume. Assume delivery of a flyer to all
households in a system: $.25 per household for systems serving fewer
than 10k, $.17 for systems serving 10-50k, $.12 for systems serving
>50k, $.04 for systems serving >100k (assumes insert into existing
mailing). 

Reduce population by 23% to take out the population that lives in
multi-family housing, who may not be adequately reached by flyers). [64
million pop in multifamily/281 million total population = 23%]

III.F(b)(2)(vii) Targeted Contact

	Assume system purchases list of targeted populations, such as pregnant
women and children. 

Based on Portland experience and internet quotes, assume $250 for
purchase of targeted list. Assume that list is purchased once. This
up-front cost is pro-rated over 3 activities and 3 years.

Assume 1 targeted communication for every 250 population served
(approximately 2000 homes for a population served of 482,500 for
Portland). 

Assume $0.44 for materials and postage. Assume 15 minutes for 100 copies
production labor.

III.F(b)(2)(viii) Provide Materials Directly to Multi-family and
Institutions

	Assume an effort to identify multi-family homes and institutions.
Assume 165 multi-family units per 100,000 population (in buildings with
10 or more units) from Census. 

Assume 5 minute per establishment to identify multi-family homes and
institutions. Assume that identification is done once. This up-front
cost is pro-rated over 3 activities and 3 years 

Assume $0.44 for materials and postage. Assume 15 minutes for 100 copies
production labor.

	Determining which activity or combination of activities systems will
regularly choose is subject to considerable uncertainty. Systems will
consider many factors in choosing activities. Certainly cost will be an
important factor, but effectiveness and ability to reach a variety of
audiences may also be considered. In the absence of information on the
selection of activities, this analysis conservatively assumes that all
activities are equally likely to be chosen. The average cost per system
for each size category is calculated and assumed to represent the
typical cost for this regulatory change. Because of the uncertainty
entailed in this assumption, Appendix I contains results of sensitivity
analyses that calculate per system costs based on alternative scenarios
for choosing activities.

The direct costs to systems for compliance with Regulatory Change
#III.F(b)(2) are summarized in Exhibit 19 and estimated to be $292,700
annually, in labor costs. Detailed estimates are provided in Appendices
H-6 through H-20.

(c) Changes to help systems maintain communication with consumers
throughout the exceedance

(c)(1) Adding Note to Customer Bills for CWSs that Exceed the Lead
Action Level

		Activities resulting from regulatory change

	Regulatory change III.F(c)(1) requires that CWSs exceeding the lead
Action Level include a specific message on every water bill during the
period of exceedance no less than quarterly, instead of on just one bill
per year. 

Costs to systems

	In order to estimate the additional direct costs associated with
regulatory change III.F(c)(1), information is needed on the number of
community water systems that exceed the lead Action Level, the frequency
of billing for water systems, and the burden associated with adding a
message to a water bill.

Number of community systems exceeding the lead Action Level:  The number
of CWSs that exceed the lead Action Level can be found in Exhibit 11.

Frequency of billing for water systems:  This analysis assumes that
water systems bill their customers 4 times per year. Therefore, a water
system will need to include the message on 3 (4-1=3) additional water
bills per year. 

Burden to include a message of water bills:  The burden to include the
message on a water bill is assumed to be 1 hour per billing cycle. The
additional burden for all 3 cycles is 3 hours, with no material costs.

The direct costs to systems for compliance with Regulatory Change
#III.F(c)(1) are summarized in Exhibit 20 and estimated to be $47,400
annually, in labor costs. Detailed estimates are provided in Appendix
H-21.

(c)(2) Posting notice on website

		Activities resulting from regulatory change

Regulatory change III.F(c)(2) requires that CWSs serving greater than
100,000  and exceeding the lead Action Level post a notice of the
exceedance on their website.

Costs to systems

		In order to estimate the additional direct costs associated with
regulatory change III.F(c)(2), information is needed on the number of
community water systems that exceed the lead Action Level and serve more
than 100,000, and the burden associated with posting a notice on a
website.

Number of community systems serving more than 100,000 and exceeding the
lead Action Level:  The number of CWSs serving more than 100,000 that
exceed the lead Action Level can be found in Exhibit 11.

Burden to post a notice on a website:  The PWSS ICR estimates that the
burden for a similar activity (posting the Consumer Confidence Report to
a public internet site) is 0.5 hours per system.  This analysis assumes
that there are no material costs associated with this activity.

The direct costs to systems for compliance with Regulatory Change
#III.F(c)(2) are summarized in Exhibit 21 and estimated to be $100
annually, in labor costs. Detailed estimates are provided in Appendix
H-22.

(c)(3) Public Service Announcements and Press Releases

		Activities resulting from regulatory change

Regulatory change III.F(c)(3) eliminates the need for systems to submit
public service announcements (PSAs) to radio and TV stations once every
6 months and add the requirement to submit a press release to these
entities once per year while under an Action Level exceedance. The 2004
ICR assumes that, for a PSA, a system will submit the text of a notice
to a radio or TV outlet, not produce a tape or video. Thus, the level of
effort required to submit a PSA is equivalent to the level of effort
required to submit a press release in the 2004 ICR. The substitution of
a press release for a PSA does not result in any change in burden.
However, the reduction in frequency from once every 6 months to once
every year results in reduced effort of 1 notification per year. 

Costs to systems

In order to estimate the additional direct costs associated with
regulatory change III.F(c)(3), information is needed on the number of
community water systems that exceed the lead Action Level serving more
than 3,300 and the reduced burden associated with 1 less notification
per year.

Number of community systems exceeding the lead Action Level serving more
than 3,300:  Under the current regulation, only community water systems
serving more than 3,300 are subject to the PSA and press release
notifications. The number of CWSs that serve more than 3,300 and exceed
the lead Action Level can be found in Exhibit 11.

Reduction in Burden for PSA’s:  The 2004 ICR estimates that it takes a
system 1 hour to prepare a press release/PSA that is supplied to 5 radio
and 5 television stations. Since systems will prepare one fewer
notifications per year, the annual reduction in burden is 1 hour per
system, plus materials and postage.

The direct costs to systems for compliance with Regulatory Change
#III.F(c)(3) are summarized in Exhibit 22 and estimated to be $-4,200
annually, in labor costs and material costs. Detailed estimates are
provided in Appendix H-23.

	d. Changes to the required timing

	There are no cost implications associated with changing the timing of
notifications.

e. Changes to the Consumer Confidence Report

(e)(1) Adding an informational statement on lead to Consumer Confidence
Report

		Activities resulting from regulatory change

Regulatory change III.F(e)(1) requires that all CWSs include an
informational statement on lead in their Consumer Confidence Report.

Costs to systems

	In order to estimate the additional direct costs associated with
regulatory change III.F(e)(1), information is needed on the number of
community water systems that already include a lead informational
statement in their CCR and the burden associated with including the lead
statement.

Number of community systems that already include the statement:  The
number of CWSs is displayed in Exhibit 5. Some systems are already
required to include an informational statement about lead in their CCRs:
systems with the 95th percentile lead level above 15 ppb. There is no
method for estimating the number of systems whose 95th percentile
exceeds 15 ppb. There is an estimate of the number of systems with a
90th percentile exceeding 15 ppb; these are the systems exceeding the
Action Level. However, there is no estimate of the additional number of
systems with 90.1th to 95th percentile values above 15 ppb. As there is
no way to account for the systems between the 90th and 95th percentiles,
only systems with an Action Level exceedance are assumed to already
include the statement, resulting in an over-estimate of the cost
impacts.

Burden to include the informational statement in the CCR: This analysis
assumes that it will take systems of all sizes an additional 15 minutes
(0.25 hours) to include the informational statement in their CCR. There
are no material costs associated with this activity.

The direct costs to systems for compliance with Regulatory Change
#III.F(e)(1) are summarized in Exhibit 23 and estimated to be $354,600
annually, in labor costs. Detailed estimates are provided in Appendix
H-24.

Total System Costs	$354,600	$0	$354,600



	Costs to Consult with State and Prepare Self-Certification Letter

There may be several opportunities for systems to consult with States
related to these public education activities.  For example, systems are
expected to consult with States on the choice of PE content and
activities, on the use of alternative delivery mechanisms besides bill
inserts, and on any needed schedule extensions. The labor associated
with consultation with States on activities is assumed to be 2 hours. 
In addition, systems will prepare a letter certifying to the State that
the required public notifications and activities have taken place.  The
labor associated with the self-certification letter is estimated at .12
hours per system (PWSS ICR, 2040-0090, page B-5), with postage and
supply costs of $0.43.  Detailed estimates are available in Appendix
H-7.

	The costs for systems associated with the changes in public education
requirements are summarized in Exhibit 24.

TOTAL	$838,000	$21,000	$859,000

Note: Totals may not add due to rounding.

Costs to States (for III.F)

	Under Regulatory Change, States will incur costs to review the language
of public notifications after Action Level exceedances and to consult
with systems on their additional activities. States will no longer have
to approve changes to the communication activities for systems serving
between 501-3,300, resulting in a slight decrease in burden.

Burden for review and consultation: The decrease in burden for States to
approve a waiver for systems serving 500-3,301 is assumed to be 0.5
(based on comparable waiver activities in the 2004 ICR). States will
require 2 hours for review and consultation on PE activities, including
message content, choice of activities, alternative mechanisms, and any
necessary schedule extensions.  States will also review the
self-certification letters at 0.10 hours per letter ((PWSS ICR,
2040-0090, page B-7).

The direct costs to States for compliance with Regulatory Change #III.F
are summarized in Exhibit 25 and estimated to be $63,000 annually, in
labor costs. Detailed estimates are provided in Appendix H-25.

4.8 	Direct Costs Associated with Regulatory Change III.G

		Activities resulting from regulatory change

		Under this regulatory change, systems would be required to reevaluate
lead service lines classified as “replaced” through testing if they
resume lead service line replacement programs. This would only apply to
a system that had (1) initiated a lead service line replacement program,
then (2) discontinued the program, and then subsequently (3) resumed the
program. When resuming the program, this system would have to reconsider
for replacement any lead service lines previously deemed replaced
through testing during the initial program. If a LSL was previously
determined to be replaced through testing, this means that the sample
previously collected from the LSL had a lead level less than the lead
Action Level so the utility was not required to physically replace it.
Utilities affected by Regulatory Change #III.G will need to put these
“tested-out” LSLs back into their inventory of lead service lines
that could be considered for replacement. Once these LSLs are back in
the inventory, we assume that they will be either retested or replaced,
with the cost of the additional testing a direct cost of the regulatory
change. The primary activities as a result of this regulatory change
include collecting samples from these LSLs and analyzing them for lead.
Replacement of lines that were previously tested-out may also occur as a
result of this change.

		Costs to systems

		Under this regulatory change, a specific subset of systems would be
required to sample previously “tested-out” lead service lines.
Estimating the cost and burden associated with these activities requires
information on several elements.

Number of systems required to perform lead service line replacement
under the LCR:  In the survey of States on LCR implementation, States
were asked “Does the state have any systems that have been required to
initiate lead service line replacement?”  Eleven States responded
“Yes” to this question. However, the survey did not ask exactly how
many systems were required to initiate lead service line replacement
programs. Six States provided sufficient information to derive a number
of systems within that State required to perform lead service line
replacement – a total of 28 systems. We assume that the remaining 5
States have 5 systems each (the average number of systems per State for
those States that did specify), plus 1 system for DC (which did not
respond to the survey) for a total of 54 systems required to perform
lead service line replacement. (See Appendix F-3 for details.)

Fraction of systems that performed required lead service line
replacement that subsequently exceed the lead Action Level:  The
regulatory change applies only to those systems that had performed
required lead service line replacement (although not necessarily total
replacement); brought compliance lead levels below the Action Level and
suspended lead service replacement; and then subsequently re-exceeded
the lead Action Level. There is no information on this small subset of
systems, although at least one system has met these criteria (DC WASA).
This analysis assumes that systems that had performed required lead
service line replacement (although not necessarily total replacement),
brought compliance lead levels below the Action Level and suspended lead
service replacement will exceed the Action Level at the same rate as the
universe of systems subject to the LCR. Thus, we assume that 1.4 percent
of the 54 systems or 1 system will exceed the Action Level and be
triggered back into lead service line replacement each year.

The number of lead service lines per system:  Recent information on the
average number of lead service lines in drinking water systems was
presented in EPA’s workshop on lead service line replacement.
According to the preliminary findings of a survey being conducted by
Black & Veatch for AWWA, 26 respondent utilities had an inventory of
558,135 lead service lines in 1992. Based on this data, the average
number of lead service lines per system is 21,467. In the absence of
specific information on the number of lead service lines in the subset
of systems that have been required to do replacement, this analysis uses
the average value from the Black & Veatch study.

The fraction of lead service lines that had been “tested-out” rather
than physically replaced:  Costs for this regulatory change apply only
to those lead service lines that have been deemed replaced through
“testing-out” in a lead service line replacement program.
Information was available for the lead service line replacement program
for one system (DC WASA) that indicated that for one year (2003), 76
percent of the lead service lines were deemed replaced through sampling,
while 24 percent were physically replaced. Because this was early in the
replacement program, the percent of lines tested out might be high in
comparison with replacement over an entire program. In the absence of
additional data, this analysis assumes that 76 percent of lead service
lines are “tested-out” and would then be put back into the inventory
upon re-exceedance.

Cost and labor to test lead service lines:  The cost and labor to test
the lead level of a lead service line is similar to the tap sampling
cost and labor for lead and copper compliance monitoring. Estimates from
previous EPA documents assume 2 hours to collect each lead service line
sample. This estimate is slightly lower than the estimate for collecting
compliance monitoring tap samples, possibly to account for differences
in the need to identify and recruit participants. The labor and material
costs to analyze the sample is assumed to be the same as for compliance
monitoring:  1 hour of labor and $9.07 material costs. Appendix F-1
provides details on the derivation of the labor and costs for lead
service line replacement monitoring.

EPA does not have information on the number of systems using the
test-out provisions rather than physically replacing lines, so this
approach is conservative because it assumes that all systems in a lead
service line replacement program are using the test-out provisions. 
Systems removing lead service lines are not impacted by this change. 
While the rate at which systems are triggered back into lead service
line replacement might be higher than the initial rate, it is offset by
the conservative assumptions regarding systems using the test-out
provisions and the universe of systems that would stop their lead
service line replacement program and later resume it because of this
change.

Replacement of lines that were previously tested-out may also occur as a
result of this change.  EPA cannot quantify the costs associated with
this change for a number of reasons.  As noted above, EPA does not have
information on the number of systems and the number of lines that have
been previously tested-out and could be impacted by this change.  This
difficulty is further compounded by the fact that some lines may have
been replaced as part of the ongoing utility replacement programs.  In
the 1991 final regulatory impact analysis, EPA cited an AWWA survey that
produced an estimate of 1% of lead service lines being replaced per year
as part of ongoing utility replacement programs.  After promulgation of
the rule, many systems modified their ongoing utility replacement
programs to replace lead lines at a higher rate.  

Where lines would have to be replaced, the unit cost of replacement is
measured in $ per foot of line being replaced.  The 1991 final
regulatory impact analysis provided a range of $26 to $51 per foot,
depending upon system size, as the unit cost for lead service line
replacement.  Using the Engineering News Record Construction Cost Index,
updated estimates would range from $41 per foot for small systems to $80
per foot for large systems.  The length of the lead service line owned
by systems will also vary, which will affect costs. 

The direct Costs to systems as a result of Regulatory Change III.G are
therefore estimated to be $109,000 annually, which includes $101,000 in
labor costs and $9,000 in material costs. Estimates of Costs to systems
are summarized in Exhibit 26 and detailed in Appendix F-2. 

		Costs to States

		No direct costs are expected for State/Primacy agencies as a result of
Regulatory Change III.G. The State/Primacy Agencies will review utility
Lead Service Line replacement program annual reports but these costs
were captured previously in the Final Regulatory Impact Analysis of
National Primary Drinking Water Regulations for Lead and Copper, April
1991.

Systems and State/Primacy Agencies will incur one-time upfront costs
associated with reviewing and implementing the overall LCR regulatory
changes. For systems, activities include reviewing the rule changes and
communicating with staff and management. For States/Primacy Agencies,
activities include regulation adoption, program development, and
miscellaneous training.

		Costs to systems

Systems covered by the Lead and Copper Rule will incur initial costs to
read the rule and communicate requirements to other staff, either
informally or through training.

All systems covered by the LCR will incur costs for the initial
activities (72,213).

The labor associated with one-time rule implementation activities varies
based on system size. For small systems serving fewer than 3,300, it is
assumed that systems take 5 hours to read the rule and communicate
relevant information to management and staff. For medium systems
(3,300-100k), it is assumed that systems take 8 hours to read the rule
and communicate relevant information to system staff. For the largest
systems (>100k), it is assumed that systems take 40 hours to read the
rule and communicate relevant information to system managers and staff.

The total costs to systems associated with the initial activities are
estimated at $10,971,000 as summarized in Exhibit 28. 

		Costs to States

Similar to one-time costs for utilities, States will also incur costs to
review the regulatory changes and implement the provisions through
regulatory adoption. 

All 57 State or Primacy Agencies will incur initial costs associated
with regulatory review and adoption.

The labor associated with these initial activities was derived from past
experience for similar drinking water rules. For the Minor Revisions to
the LCR, EPA assumed that regulatory adoption activities would require
0.25 FTE.  For another recent rule of similar scope, the Filter Backwash
Rule, EPA estimated that regulatory review and adoption activities would
require 0.125 FTE.   The analysis assumed the level of effort for this
rule would be slightly higher than these other two rules because of the
interactive nature of some of the rule provisions: .33 FTE or 600 hours
to review and adopt the regulatory changes.

The total direct costs for initial implementation activities for States
is summarized in Exhibit 28 and detailed in Appendix G-2.

5	Indirect Cost and Health Risk Reduction Implications of Rule Changes

		The revisions will result directly in increased administrative costs
for systems and States – costs to conduct the increased required
monitoring, notification, and testing and to meet the more tightly
specified requirements for these activities. The revisions do not affect
the Action Levels, corrosion control requirements, line replacement
requirements, or other provisions in the existing rule that directly
determine the degree to which the rule abates risks from lead and
copper. However, the increase and change in administrative activities
that will result from the revisions will result in the generation of new
information (e.g., more monitoring data, some of which may show
exceedances), and some systems or individuals will likely respond to
this new information by taking measures to abate lead and copper
exposures. We thus believe the revisions will have an indirect impact on
the degree to which lead and copper control measures may be implemented,
and on the overall benefits and costs from the LCR. 

		The potential impacts of these revisions on lead and copper abatement
measures are quite speculative. The revisions will require some systems
to generate new information which in some cases may be provided to
States and customers. The information that is generated may turn out to
suggest lead and copper threats that would not otherwise have been
discovered (or such threats might be discovered sooner than they
otherwise would have). Upon obtaining this information, a system itself,
the State, or some of the system’s customers might take actions to
address these threats. The revisions, however, require only the
generation of the information. They do not specifically require adoption
of any practices or measures to reduce the levels of lead and copper in
drinking water. It is difficult to project now what the content will be
of the information generated pursuant to the regulation, and it is even
further uncertain how systems and individuals might act in response to
the new information when it is developed. For these two reasons – the
lack of any direct requirement in the revisions for systems or
individuals to implement exposure reduction measures, and the
uncertainty in tracing the linkages from the regulation to new
information to exposure prevention measures to changes in risks and
costs – EPA is unable to quantify the eventual indirect impacts on
risks, benefits, and costs that might ensue from these regulatory
changes. EPA does expect that overall benefits from the LCR will
increase, as a result of the indirect effect of the revisions on the
actions of individual consumers and systems. In this section, we provide
a qualitative picture of what some of these indirect impacts might be.

		Exhibit 29 summarizes the manner in which each revision might perhaps
induce actions that reduce lead and copper exposures, resulting
indirectly in both costs and health risk reduction benefits. The Exhibit
shows only the indirect costs and benefits that might result from the
provisions; the Exhibit does not repeat the direct cost impacts that
were estimated in Section 4.Exhibit 29: Summary of Preliminary Cost and
Health Risk Reduction Implications of the LCR Short Term Rule Changes

Administrative Impact	Potential Response	Implication for Indirect Costs
Implication for Health Risk Reductions

Regulatory change III.A – Minimum number of samples required

NTNCWSs that have fewer than 5 taps in States that exercise their
discretion to allow 1 sample per tap may take fewer samples.	Some
NTNCWSs may take fewer samples, but could be more easily triggered into
an Action Level exceedance with greater frequency because of the
calculation of the 90th percentile (highest sample).	Additional systems
that exceed the Action Level may incur costs for: 1) compliance measures
(e.g., corrosion control, LSL replacement); and 2) increased monitoring
when they revert to standard monitoring.	To the extent there are actions
taken to reduce lead due to additional exceedances, there will be
resulting health risk reductions.

Regulatory change III.B - Definitions for monitoring and compliance
periods

Clarifies that the time limits within which various items must be
completed following an Action Level exceedance begin with the end of the
monitoring period when the exceedance was found (typically September)
rather than beginning with the end of the calendar year.	May accelerate
by several months the deadlines for initiation and completion of all
actions following an exceedance.	May accelerate by several months the
time when costs for public education and compliance efforts are incurred
following an Action Level exceedance.	Corresponding possible several
month acceleration of health risk reduction benefits.

Regulatory change III.C – Reduced monitoring criteria 

A system that is conducting reduced monitoring will have to revert to
standard monitoring if it exceeds the lead Action Level. Under existing
regulations, a system could remain on reduced monitoring despite an
Action Level exceedance if treated water quality parameters are within
specified limits.	Such systems will have to monitor more sites during
each monitoring period (sampling the larger, “standard”, number of
sites rather than the “reduced” number of sites)  Additional
monitoring costs will result, but these are direct costs, considered in
Section 4.

Monitoring more sites will improve the statistical accuracy of the
judgment on whether the system really does or does not exceed the lead
Action Level. Both Type 1 and Type 2 errors will be reduced (see Note
1). Monitoring more sites is not expected systematically to either
increase or decrease a system’s likelihood of being found to exceed
the Action Level.

Monitoring more sites could either hasten or delay the time at which a
system will draw a conclusion from its monitoring as to whether the
Action Level is exceeded.	Greater statistical accuracy and better
decisions on whether a system really does exceed the Action Level means
that compliance efforts, public education, etc. will be better targeted
at systems where they are warranted.

It is possible that monitoring and sampling sooner after an Action Level
exceedance could reduce costs if the re-sampling shows values under the
Action Level. For example, public notification and other measures
(flushing, pitchers) might last for only 6 months rather than a year if
re-sampling after 6 months is below the Action Level. 	Potential impacts
on benefits will be like those on costs – varying from system to
system. Standard monitoring will cause some systems to implement
compliance measures and reduce risks sooner and for longer.

Overall improved statistical accuracy with standard monitoring will tend
to mean that compliance efforts and risk reduction will focus on systems
where there are larger risks.

Sampling sooner or more intensively with regular monitoring after an
Action Level exceedance could result in health risk reductions. If
sampling demonstrates continued exceedance, a system would have quicker
feedback on effectiveness of actions and could proceed more quickly to
other measures to reduce lead. In the case of sampling 6 months vs. 12
months after an exceedance, further actions that would reduce lead could
begin 6 months earlier.

Regulatory change III.D – Advanced notification and approval
requirement for treatment change or source addition

System notifies State of long-term treatment change or source water
addition prior to implementation for State approval.

Some States already require review and approval, so the provision has no
or little impact in these States.	The State may request that the system
provide additional information or require the system to conduct sampling
or pilot studies prior to the treatment change becoming effective. This
could delay implementation of the treatment change. It could also result
in modification of a change that could have had negative impacts.	A net
decrease in treatment costs may actually occur. Early State review may
avoid potentially costly mistakes. If a State has concerns or
suggestions about the impact of a treatment change, it will be less
expensive to modify treatment before the changes are made, rather than
after the fact.	Health risk reductions could result if pre-emptive
modifications are made to proposed treatment changes that reduce the
possibility of lead leaching.

Regulatory change III.E – Notification of sampling results

Systems notify customers of tap monitoring results.	For dwellings with a
tap where the monitored concentration exceeds the Action Level, some
fraction of owners/occupants will decide to act to reduce the
concentration, perhaps replacing lead lateral or fixtures, installing
filters, using bottled water, adopting flushing practices or contacting
the utility for further information or request for additional sampling.
Owner and/or occupants will bear the costs of whatever exposure
reduction measures they decide to implement.	Reduced lead/copper levels
will reduce health risks for the occupants of any dwelling where
exposure-reduction measures are implemented.

System letters to all homeowners may improve overall awareness of
sources of lead, and strategies to reduce exposure to lead.

Regulatory change III.F – Revisions to public education requirements

Systems use a variety of methods to more effectively communicate with
customers about potential risks due to lead.	For a system with a lead
Action Level exceedance or a lead detect, a greater fraction of
customers will be made aware of potential risks due to lead levels and
may act to reduce lead levels.	Owner and/or occupants will bear the
costs of whatever exposure reduction measures they decide to implement.
Inclusion of statement in the CCR may improve overall awareness of
sources of lead, and strategies to reduce exposure to lead. Reduced lead
levels will reduce health risks for the occupants of any dwelling where
exposure-reduction measures are implemented.

Regulatory change III.G – Reevaluation of Lead Service Lines deemed
replaced through testing

The system that exceeds the lead Action Level following a treatment
change will need to identify all lead service lines that had previously
been determined to be replaced via sampling. The utility will need to
develop a testing schedule and contact all affected homeowners regarding
the testing program.	It is expected that most homeowners that utilize a
lead service line will be supportive of the testing program.

Homeowners may be interested in physical replacement of the LSL or
additional sampling, particularly if the sample’s lead level exceeds
the lead Action Level.

The cost of retesting a previously “tested-out” line is a direct
cost of the rule.

	If a previously “tested-out” line is retested and is over the
Action Level, this line will eventually be replaced, an indirect cost
that is attributable to the rule. However, it could take many years
before this cost is incurred.

There may be short term implications associated with increasing the
number of lead service lines in the baseline. If the number of lines
that need to be replaced or tested out is calculated based on the size
of the inventory, a slightly larger inventory will mean a slight
increase in the number of lines needed to reach the 7 percent
replacement goal.	If a previously “tested-out” line is retested and
is over the Action Level, health risk reductions will occur when the
line is replaced.



Note 1 (see Regulatory Change III.C): In statistical terms, type 1 and
type 2 errors are errors that can occur while testing a statistical
hypothesis. In this case, the hypothesis may be that 90 percent of
samples will have a lead level < 15 ppb. When a utility collects a
limited number of samples thus generating limited lead data points, it
is possible that the hypothesis could be rejected (found to be not true)
even when it is true (a Type 1 error) or that the hypothesis is not
rejected (found to be true) when it is in fact false (a Type 2 error).
These errors occur because of sampling variability and the occurrence of
unrepresentative samples. These errors can be minimized by collecting
more samples. 

		As shown in the Exhibit, four regulatory revisions seem more likely
than the others to potentially influence systems or individuals to
undertake exposure prevention measures. These include provisions III.C,
III.E, III.F, and III.G. Although it is not feasible to quantify the
monetary value of these possible exposure reductions, the relationship
of benefits to costs for reductions in lead in drinking water exposure
in general suggests that benefits would exceed costs if quantified. For
example, in the 1991 RIA for the Lead and Copper Rule, the ratio of
quantified benefits to costs is 6.7 to 1, meaning that there were 6.7
times more benefits than costs.  If this relationship continues to hold
true, it’s likely that any direct and indirect costs for the
regulatory changes that result in exposure reductions would be offset by
health risk reduction benefits.

6	Administrative Requirements

6.1 	Executive Order 12866:  Regulatory Planning and Review

Under Executive Order 12866, [58 Federal Register 51735 (October 4,
1993)] this action is a "significant regulatory action".  Accordingly,
EPA submitted this action to the Office of Management and Budget (OMB)
for review under EO 12866 and any changes made in response to OMB
recommendations have been documented in the docket for this action.

This document represents an analysis of the potential costs and benefits
associated with this action.  A copy of this analysis is available in
the docket for this action and the analysis is briefly summarized in
Section IV of the preamble for the final rule.

6.2 	Paperwork Reduction Act

The information collection requirements in this rule have been submitted
for approval to the Office of Management and Budget (OMB) under the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq.  The information
collection requirements are not enforceable until OMB approves them.

Need for the Information Collection

 

	EPA requires current information on lead and copper contamination to be
provided to consumers and states. Recent highly publicized incidences of
elevated drinking water lead levels prompted EPA to review and evaluate
the implementation and effectiveness of the LCR on a national basis.  As
a result of this multi-part review, EPA identified seven targeted rule
changes that clarify the intent of the LCR and enhance protection of
public health through additional information gathering and public
education.  Consumers and states will use the information collected as a
result of the short-term revisions to the LCR to determine the
appropriate action they should undertake. The rule revisions described
in Section 3 of this document are intended to improve the implementation
of the LCR, and do not alter the original maximum contaminant level
goals or the fundamental approach to controlling lead and copper in
drinking water. 

Section 1401(1)(D) of the SDWA requires that regulations contain
“criteria and procedures to assure a supply of drinking water which
dependably complies with such maximum contaminant levels, including
accepted methods for quality control and testing procedures to insure
compliance with such levels and to insure proper operation and
maintenance of the system....” Furthermore, Section 1445(a)(1) of the
SDWA requires that every person who is a supplier of water “shall
establish and maintain such records, make such reports, conduct such
monitoring, and provide such information as the Administrator may
reasonably require by regulation to assist the Administrator in
establishing regulations…,in determining whether such person has acted
or is acting in compliance....” In addition, Section 1413(a)(3) of the
SDWA requires States to “keep such records and make such reports...as
the Administrator may require by regulation.”

Section 1412(b) of the SDWA, as amended in 1996, requires the Agency to
publish maximum contaminant level goals and promulgate NPDWRs for
contaminants that may have an adverse effect on the health of persons,
are known to or anticipated to occur in PWSs, or, in the opinion of the
Administrator, present an opportunity for health risk reduction. The
NPDWRs specify maximum contaminant levels or treatment techniques for
drinking water contaminants (42 USC 300g-1). Section 1412 (b)(9)
requires that EPA no less than every 6 years review, and if appropriate,
revise existing drinking water standards. Promulgation of the LCR
implements these statutory requirements 

Burden Estimate

The universe of respondents for this ICR is comprised of the 52,838 CWSs
and 19,375 NTNCWSs, for a total of 72,213 systems, and 57 State primacy
agencies. Exhibit 30 presents a summary of average annual burden and
costs for the ICR period of late September 2007 through late September
2010 for a lower bound and upper bound estimate (depending on
assumptions about the timing of rule implementation).

The average annual system burden is estimated at 189,369 - 271,997
hours. The average annual system costs are projected at $5.6 to $8.4
million. 

		The average annual State burden is estimated at 17,628 – 25,125
hours. The average annual State costs are projected at $0.8 - $1.1
million. 

		These annual costs reflect the costs to systems and States for the
first three years after rule promulgation and consist of the one-time
direct costs for rule review and implementation, as well as activities
related to the seven regulatory changes.  

Bottom Line Burden Hours and Costs

		The average annual burden and costs for the initial three year period
is summarized in Exhibit 30. The total burden and costs for each
regulatory change is explained in Appendices B and C of the ICR document
for the final rule.

Burden Statement

For the ICR period of September 2007 through September 2010 associated
with the short-term revisions to the LCR, the average burden for systems
to implement the requirements of the short-term LCR revisions is
estimated to be 2.6 – 3.8 hours per system per year. The average
annual cost to systems is expected to be $77 - $117 per system per year.
System burden includes time required read and understand the rule
requirements and communicate those requirements to system personnel and
management, as well as activities related to the regulatory changes. The
average burden for State agencies is estimated to be 309 - 441 hours per
State per year. This burden includes the time to inform systems of the
requirements and perform primacy-related activities, as well as
activities related to the regulatory changes. The estimated annual State
cost is estimated to be $13,500 - $19,300 per State per year.

Burden means the total time, effort, or financial resources expended by
persons to generate, maintain, retain, or disclose or provide
information to or for a Federal agency. This includes the time needed to
review instructions; develop, acquire, install, and utilize technology
and systems for the purposes of collecting, validating, and verifying
information, processing and maintaining information, and disclosing and
providing information; adjust the existing ways to comply with any
previously applicable instructions and requirements; train personnel to
be able to respond to a collection of information; search data sources;
complete and review the collection of information; and transmit or
otherwise disclose the information. 

An agency may not conduct or sponsor, and a person is not required to
respond to a collection of information unless it displays a currently
valid OMB control number.  The OMB control numbers for EPA's regulations
in 40 CFR are listed in 40 CFR part 9.  When this ICR is approved by
OMB, the Agency will publish a technical amendment to 40 CFR part 9 in
the Federal Register to display the OMB control number for the approved
information collection requirements contained in the final rule.

6.3 	  SEQ CHAPTER \h \r 1 Regulatory Flexibility Act 

The Regulatory Flexibility Act (RFA) generally requires an agency to
prepare a regulatory flexibility analysis of any rule subject to notice
and comment rulemaking requirements under the Administrative Procedure
Act or any other statute unless the agency certifies that the rule will
not have a significant economic impact on a substantial number of small
entities. Small entities include small businesses, small organizations,
and small governmental jurisdictions.

The RFA provides default definitions for each type of small entity.
Small entities are defined as: (1) a small business as defined by the
Small Business Administration’s (SBA) regulations at 13 CFR 121.201;
(2) a small governmental jurisdiction that is a government of a city,
county, town, school district or special district with a population of
less than 50,000; and (3) a small organization that is any
“not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.”  However, the RFA also authorizes
an agency to use alternative definitions for each category of small
entity, “which are appropriate to the activities of the agency”
after proposing the alternative definition(s) in the Federal Register
and taking comment. 5 USC 601(3) - (5). In addition, to establish an
alternative small business definition, agencies must consult with
SBA’s Chief Counsel for Advocacy. 

For purposes of assessing the impacts of today’s final rule on small
entities, EPA considered small entities to be public water systems
serving 10,000 or fewer persons. As required by the RFA, EPA proposed
using this alternative definition in the Federal Register (63 FR 7620,
February 13, 1998), requested public comment, consulted with the Small
Business Administration (SBA), and finalized the alternative definition
in the Consumer Confidence Reports regulation (63 FR 44511, August 19,
1998). As stated in that Final Rule, the alternative definition would be
applied to this regulation as well.

After considering the economic impacts of today’s final rule on small
entities, EPA certifies that this action will not have a significant
economic impact on a substantial number of small entities. The small
entities directly regulated by this final rule are small public water
systems serving 10,000 or fewer people on an annual basis. EPA has
determined that 68,286 small systems will be affected by the changes to
the LCR. Exhibit 33 provides a summary of these small systems, by size
category and system type.

Exhibit 33: The Number of Small Systems Affected by the Final Rule
Changes

Size	CWS	NTNCWS	TOTAL Small

<=100	13,766	9,548	23,314

101-500	16,240	6,997	23,237

501-1,000	5,914	1,925	7,839

3,301-10,000	4,707	96	4,803

Total	48,925	19,361	68,286



However, not all of these small entities will be affected and incur
direct costs for all of the regulatory changes. In many cases, only a
relatively small subset of these systems will have to change practices
to comply with the regulatory changes. Exhibit 34 provides an estimate
of the number of small systems that will incur direct costs for each of
the final regulatory changes.

Activities and Costs Associated With Rule Changes for Small Systems

EPA has estimated the burden and costs associated with the regulatory
changes, as described in section 4 of this document. The basis for many
of these input values and assumptions are described in detail in the
Economic Analysis, Section 4. The following summarizes the costs
estimated for small systems.

One-Time Activities

All small systems subject to the Lead and Copper Rule will be expected
to incur some costs to read the rule changes and communicate
requirements as necessary. The level of effort associated with these
activities could range from 5 - 8 hours for all small systems. The
average cost per system for these activities is estimated at $138, for a
total cost of $9,404,000 for all 68,286 small systems. This assumes an
hourly fully loaded labor cost for small system employees ranging from
$23.86 to $33.96 (see Appendix B for derivation).

Activities for Regulatory Change III.A

Under Regulatory Change III.A, small systems with fewer than 5 taps in
States that allow 1 sample per tap will prepare and submit to the State
a one-time letter verifying the applicable number of taps and requesting
the use of the alternative sampling.  Eleven States supported the
alternative sampling in their comments on the proposed rule.  EPA
estimates that there are 3,692 small systems with fewer than 5 taps in
the 11 States (plus Alaska for small CWSs).  Preparing the one-time
request letter results in a one time cost of $28 per system. Total costs
for all small systems are estimated at $104,000 per year.

Activities for Regulatory Change III.C

Under Regulatory Change III.C, all systems that exceed the lead Action
Level are triggered into regularly scheduled lead tap monitoring.
Additional costs are associated with taking lead samples more frequently
and reporting the results to States. EPA estimates that 854 small
systems exceed the lead Action Level each year. Changing from reduced
tap monitoring to regularly scheduled tap monitoring would result in an
average cost increase of $2,258 per year per system. Total costs for all
small systems are estimated at $1,929,000 per year.

Activities for Regulatory Change III.D

Small systems that are changing treatment or adding a source would incur
additional costs under Regulatory Change III.D to prepare data in
support of treatment changes or source addition, to submit the data to
the State for review, and to coordinate with the State during the
review. These activities are estimated to take an additional 7.5 hours
per system for each treatment change or source addition. The cost for
each small system that is changing treatment or adding a source is
estimated at $196. The total cost for all small systems is estimated at
$198,000 per year.

Activities for Regulatory Change III.E

Most small systems are expected to incur additional costs under
Regulatory Change III.E when they are required to notify consumers of
tap monitoring results. The activities associated with notifying
customers vary based on the type and size of the system and include the
effort to prepare a self-certification letter for the State. The average
cost for small systems to notify customers is estimated at approximately
$17 annually. This estimate assumes one labor hour to prepare a customer
notification letter per system, 0.12 hours to prepare the
self-certification letter, and $0.43 in material costs per sample for
CWSs.  EPA assumed one labor hour plus 0.12 hours for NTNCWSs, with
negligible material costs.  It is important to note that the majority of
small systems are assumed to meet the lead action level and are assumed
to be on triennial monitoring.  Therefore, this requirement will only
affect them once every three years. The total cost to all small systems
is estimated at $1,060,000.

Activities for Regulatory Change III.F

Different provisions of Regulatory Change III.F apply to different
subsets of systems. All small community water systems will incur costs
to include a statement on lead in the Consumer Confidence Report, at an
average cost of $7 per system, based on the assumption of 0.25 hours to
add an informational statement on lead to the CCR. Small community water
systems that exceed the Lead Action Level will incur costs from a
variety of public education activities, at an average cost per system of
$265. The total cost for all small systems is estimated at $569,000.

Activities for Regulatory Change III.G

Regulatory Change III.G applies to systems that had “tested out”
lead service lines as part of a lead service line replacement program
and then re-exceed the Action Level. For the purposes of subsequent lead
service line replacement efforts, the previously “tested-out” lines
would go back into the inventory for possible re-testing and/or
replacement. Only a handful of systems are expected to be in this
situation, estimated at 1 system per year. This analysis assumes that
the 1 system is not a small system.  There is no evidence that small
systems would be triggered into this regulatory change cost any more
frequently than other systems.

Average Costs Per Small System

The average compliance cost for all small systems covered by the LCR for
the final rule changes is minimal:  $55 per system in annual costs.
However, there is a fairly wide range in the costs that a system could
face. All systems will incur the $138 one-time implementation cost, but
the additional annual costs could be as low as $0 for small NTNCWSs that
already notify customers of tap monitoring results. Systems that do not
already notify customers of results will incur $17 per year. Small CWSs
will incur $7 per year to include a statement on the CCR. The roughly 2
percent of systems that are making a treatment change or source addition
would incur an additional $196 in the year they make the change. 

At the high end, the roughly 1.4 percent of small systems that exceed
the lead Action Level would incur an additional $2,523 per year. If a
system incurred all annual costs, the total would be $2,743 per year.

Measuring Significant Impact of Rule Costs

The costs to small systems are compared against average revenues for
small systems from all revenue sources.  Small systems can be one of
three types of small entities – small businesses, small governments,
or small non-profits.  The revenue estimate used for assessing impacts
to small systems in this rule is derived from two sources:  (1) EPA’s
2000 Community Water System Survey (CWSS) and (2) the 2002 Census of
Governments.  Data from these two sources are used to calculate an
average revenue estimate for all small systems serving less than 10,000
customers.  The weighted average revenue from all revenue sources for
small systems is estimated at $2,166,700 per year.  A detailed
description for this revenue estimate is shown in Appendix K of this
document.    

Using the average cost of the regulatory changes for small systems, the
one-time costs represent roughly 0.008 percent of annual revenues from
all revenue sources.  The $55 average annual costs represent 0.003
percent of average annual revenues from all revenue sources. Roughly 1.4
percent of the systems would incur annual costs of $2,523, which is
approximately .0116 percent of revenues from all sources.  This maximum
annual cost is approximately 0.127 percent of annual revenues from all
sources.

In summary, the costs for the average small system due to the regulatory
changes are estimated to be less than 1 percent of revenues from all
sources (0.003 percent). In addition, highest possible annual impact is
0.127 percent of annual revenues.  Based on this analysis, EPA concludes
that this final rule will not have a significant impact on a substantial
number of small entities.

6.4 	Unfunded Mandates Reform Act

	  SEQ CHAPTER \h \r 1 Title II of the Unfunded Mandates Reform Act of
1995 (UMRA), Public Law No. 104-4, establishes requirements for Federal
agencies to assess the effects of their regulatory actions on State,
local, and Tribal governments and the private sector. Under section 202
of the UMRA, EPA generally must prepare a written statement, including a
cost-benefit analysis, for proposed and final rules with "Federal
mandates" that may result in expenditures to State, local, and Tribal
governments, in the aggregate, or to the private sector, of $100 million
or more in any one year. Before promulgating an EPA rule for which a
written statement is needed, section 205 of the UMRA generally requires
EPA to identify and consider a reasonable number of regulatory
alternatives and adopt the least costly, most cost-effective or least
burdensome alternative that achieves the objectives of the rule. The
provisions of section 205 do not apply when they are inconsistent with
applicable law. Moreover, section 205 allows EPA to adopt an alternative
other than the least costly, most cost-effective or least burdensome
alternative if the Administrator publishes with the final rule an
explanation why that alternative was not adopted. Before EPA establishes
any regulatory requirements that may significantly or uniquely affect
small governments, including Tribal governments, it must have developed
under section 203 of the UMRA a small government agency plan. The plan
must provide for notifying potentially affected small governments,
enabling officials of affected small governments to have meaningful and
timely input in the development of EPA regulatory proposals with
significant Federal intergovernmental mandates, and informing,
educating, and advising small governments on compliance with the
regulatory requirements.

  SEQ CHAPTER \h \r 1 EPA has determined that this rule does not contain
a Federal mandate that may result in expenditures of $100 million or
more for State, local, and Tribal governments, in the aggregate, or the
private sector in any one year. The total upfront costs of this action
to States and public water systems are estimated at $12.725 million,
with estimated annual costs to States and public water systems ranging
from $5.9 to $6.3 million. Systems and State/Primacy agencies will incur
one-time upfront costs associated with reviewing and implementing the
overall LCR regulatory changes. For systems, activities include
reviewing the rule changes and communicating requirements to staff. For
States/Primacy agencies, activities include regulation adoption, program
development, and miscellaneous communication with systems. Systems and
States will also incur annual costs consisting of the costs to implement
the regulation. Annual costs to systems include the costs of reporting,
monitoring, and public education. Annual costs to States consist of the
costs of reviewing water system information. Thus, today’s rule is not
subject to the requirements of sections 202 and 205 of the UMRA.

	EPA has determined that this rule contains no regulatory requirements
that might significantly or uniquely affect small governments.  The
regulation applies to all owners/operators of public water systems, not
uniquely to those owners/operators that are small entities, and, for
most systems, requires minimal expenditure of resources. Since these
regulatory revisions affect all system sizes and the impact on the
average small system will be 0.11 percent of revenues, the regulatory
revisions to the LCR are not subject to the requirements of section 203
of UMRA.

	Nevertheless, in developing this rule, EPA consulted with State and
local officials (including small entity representatives) early in the
process of developing the proposed regulation to permit them to have
meaningful and timely input into its development. EPA held five
workshops in 2004-2005 to elicit concerns and suggestions from
stakeholders on various issues related to lead in drinking water. These
workshops covered the topic areas of simultaneous compliance, sampling
protocols, public education, lead service line replacement, and lead in
plumbing. Expert participants from utilities, academia, state
governments, consumer and environmental groups, and other stakeholder
groups participated in these workshops to identify issues, propose
solutions, and offer suggestions for modifications and improvements to
the LCR. These workshops are described in greater detail in previous
sections of this document.   

6.5 	Executive Order 13132:  Federalism

  SEQ CHAPTER \h \r 1 Executive Order 13132, entitled “Federalism”
(64 FR 43255, August 10, 1999), requires EPA to develop an accountable
process to ensure “meaningful and timely input by State and local
officials in the development of regulatory policies that have federalism
implications.”  “Policies that have federalism implications” is
defined in the Executive Order to include regulations that have
“substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.”  

The final rule does not have federalism implications. It does not have
substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government, as
specified in Executive Order 13132. The rule is consistent with, and
only makes revisions to, the requirements under the current national
primary drinking water regulations for lead and copper. The existing
rule imposes requirements on public water systems to ensure that water
delivered to users is minimally corrosive, to treat source water, remove
lead service lines and provide public education where necessary to
ensure public health protection.   This rule does not make any
significant changes to these requirements, but, as explained elsewhere
in this document, makes revisions and clarifications to the rule’s
requirements to enhance the efficiency and effectiveness of current
requirements.

Nevertheless, EPA did consult with State and local officials early in
the process of developing the proposed regulation as described in
section on the Unfunded Mandates Reform Act.

6.6 	Executive Order 13175:  Consultation and Coordination With Indian
Tribal Governments

Executive Order 13175, entitled “Consultation and Coordination with
Indian Tribal Governments” (65 FR 67249, November 9, 2000), requires
EPA to develop an accountable process to ensure “meaningful and timely
input by tribal officials in the development of regulatory policies that
have tribal implications.”  

  

The final rule does not have tribal implications as specified in
Executive Order 13175. This rule does not significantly or uniquely
affect the communities of Indian Tribal governments, nor does it impose
substantial direct compliance costs on those communities. The provisions
of this rule apply to all community and non-transient non-community
water systems. Tribal governments may be the owners or operators of such
systems, however, nothing in today’s provisions uniquely affects them.
EPA therefore concludes that this rule does not significantly or
uniquely affect the communities of Indian tribal governments. Thus,
Executive Order 13175 does not apply to this rule.  

6.7 	Executive Order 13045:  Protection of Children from Environmental
Health Risks and Safety Risks

	Executive Order 13045: “Protection of Children from Environmental
Health Risks and Safety Risks” (62 FR 19885, April 23, 1997) applies
to any rule that: (1) is determined to be “economically significant”
as defined under Executive Order 12866, and (2) concerns an
environmental health or safety risk that EPA has reason to believe may
have a disproportionate effect on children. If the regulatory action
meets both criteria, the Agency must evaluate the environmental health
or safety effects of the planned rule on children, and explain why the
planned regulation is preferable to other potentially effective and
reasonably feasible alternatives considered by the Agency.

	This final rule is not subject to the Executive Order because it is not
economically significant as defined in Executive Order 12866.  The rule
does not change the core LCR requirements in place to assure the
protection of children from the effects of lead in drinking water,
rather the changes will improve the implementation of these provisions.
Moreover, EPA believes that this action is consistent with Executive
Order 13045 because it further strengthens the protection to children
from exposure to lead and copper via drinking water, as this rule
enhances the implementation of the LCR in the areas of monitoring,
customer awareness, and lead service line replacement. This rule also
clarifies the intent of some unclear provisions in the LCR. These
changes ensure and enhance more effective protection of public health
through the reduction in lead exposure. 

  SEQ CHAPTER \h \r 1   

6.8		Executive Order 13211:  Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use   

	  SEQ CHAPTER \h \r 1 The  final rule is not a “significant energy
action” as defined in Executive Order 13211, “Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use” (66 FR 28355 (May 22, 2001)) because it is not likely to have a
significant adverse effect on the supply, distribution, or use of
energy. The rule provides clarifications and modifications to the
existing LCR rule language only.    

	The final rule does not affect the supply of energy as it does not
regulate power generation. The public and private utilities that are
affected by this regulation do not, as a rule, generate power. The
revisions to the LCR do not regulate any aspect of energy distribution
as the utilities that are regulated by the LCR already have electrical
service. Finally, these regulatory revisions do not adversely affect the
use of energy as EPA does not anticipate that a significant number of
drinking water utilities will add treatment technologies that use
electrical power to comply with these regulatory revisions. As such, EPA
does not anticipate that this rule will adversely affect the use of
energy. 

6.9 	National Technology Transfer and Advancement Act

	  SEQ CHAPTER \h \r 1 Section 12(d) of the National Technology Transfer
and Advancement Act of 1995 (“NTTAA”), Public Law No. 104-113, 12(d)
(15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in
its regulatory activities unless to do so would be inconsistent with
applicable law or otherwise impractical. Voluntary consensus standards
are technical standards (e.g., materials specifications, test methods,
sampling procedures, and business practices) that are developed or
adopted by voluntary consensus standards bodies. The NTTAA directs EPA
to provide Congress, through OMB, explanations when the Agency decides
not to use available and applicable voluntary consensus standards. 

	  SEQ CHAPTER \h \r 1  The final rule may involve voluntary consensus
standards in that it requires additional monitoring for lead and copper
in certain situations, and monitoring and sample analysis methodologies
are often based on voluntary consensus standards.  However, the final
rule does not change any methodological requirements for monitoring or
sample analysis, only, in some cases, the required frequency and number
of samples.  Also, EPA’s approved monitoring and sampling protocols
generally include voluntary consensus standards developed by agencies
such as the American National Standards Institute (ANSI) and other such
bodies wherever EPA deems these methodologies appropriate for compliance
monitoring.

(a) State labor costs are from the "2001 ASDWA Drinking Water Program
Resource Needs Self Assessment". In 2000, the United States General
Accounting Office used a previous version of this model to estimate
nationwide drinking water program needs for Congress. The tool was later
updated and improved based on comments from 27 States. To make the model
easier to use, ASDWA established suggested salary and benefit ranges
(i.e., default values), resource needs for the various NPDWRs, and other
key variables. These hourly estimates are based on the default annual
rates for 2007 that are provided in the model. The model assumes 1,800
work hours per full-time equivalent employee. Hourly rate labor costs
are adjusted to account for fringe benefits (i.e., holidays, sick days,
vacation, pension, health, dental, and life insurance); and overhead
(i.e., office space, furniture, utilities, copiers, fax machines,
postage, basic computing needs, etc.).

Appendix B

Derivation of System Labor Rates

Appendix B-1: Derivation of System Labor Rates

		Labor costs for systems were taken from the report Labor Costs for
National Drinking Water Rules prepared by SAIC in October 2003 for
EPA’s Office of Ground Water and Drinking Water.  Exhibits 20 and 21
of that report summarized recommended average technical wage rates and
average managerial wage rates by system size for EPA to use in cost
analyses.  These rates are summarized below.

	These loaded wage rates are updated to a fourth quarter 2006 level
using the Employment Cost Index for wages and salaries in utilities
(based on the NAICS classification system).  The index value is 93.0 for
the first quarter of 2003 and 103.5 for the fourth quarter of 2006,
resulting in a factor of 1.113.  To represent the composition of staff
at PWSs of smaller sizes (e.g., systems serving fewer than 3,300
people), EPA uses only the technical rate. For systems serving 3,300 or
more people, EPA uses a ratio of 80 percent technical labor to 20
percent managerial labor to arrive at a weighted labor rate of $33.96
for systems serving 3,301-10,000 people, $34.59 for systems serving
10,001-100,000 people, and $39.23 for systems serving greater than
100,000 people.

Appendix C-2: Derivation of estimates of system labor for tap
monitoring

Unlike most drinking water regulations that require sampling at entry
points to the distribution system, the LCR requires that tap water
samples be collected at kitchen or bathroom taps of residences and other
buildings to capture the impact of distribution system and household
plumbing materials on drinking water lead and copper levels. This
requirement significantly complicates sample collection, requiring that
water systems identify potential customers to monitor based on a tiered
system, recruit those customers to participate, and coordinate with
these customers to collect tap samples. Procedures associated with lead
and copper tap sampling include collecting a 1-liter first draw sample
from a tap regularly used for consumption where the water has stood in
the pipes for at least 6 hours (e.g., no flushing, showering, etc.).
Residents may collect samples, but they must follow specific
instructions as to the sample collection procedures. Systems then
analyze the samples for lead and copper content, calculate the 90th
percentile value for the system to assess compliance, and report the
results to the State.

Sample Collection

	

	In order to collect drinking water samples from customer sites to
conduct compliance monitoring for the LCR, systems undertake the
following activities:

Identification of potential monitoring locations based on the Tier
system in the LCR,

Recruitment of customers at the locations to voluntarily participate in
sampling,

Distribution of sample materials and instructions,

Coordination with customers during sampling to remind them and answer
questions,

Collection of samples from customer locations, and

Review of samples and validation that appropriate collection procedures
have been followed.

The labor required by systems to conduct lead and copper tap sampling to
assess compliance with the LCR has been estimated previously by several
EPA studies. The April 1991 “Final Regulatory Impact Analysis of
National Primary Drinking Water Regulations for Lead and Copper”
estimates that it takes 2 hours for public water system personnel to
arrange for and collect each lead and copper sample.

These estimates have been refined since the 1991 RIA for the LCR. The
June 1999 Information Collection Request states that “sample
collection (the labor required for travel, gaining access to the
sampling station, and sample collection) takes 2.5 hours per
sample…”  The estimate of 2.5 hours per sample for lead and copper
tap sampling collection is also used in the 2004 ICR and, in the absence
of new information, has been applied in this analysis.

Sample Analysis

	The cost to analyze a compliance sample for lead and copper is based on
the fee charged by certified commercial laboratories.  This fee includes
both the cost of labor and materials.  The June 1999 ICR assumed a
commercial fee of $30 to analyze a sample for lead and copper.  Updated
to current dollars (4th Qtr 2006), the fee is estimated at $36.34 per
sample.  To validate that the updated analysis fee is reasonable,
publicly available estimates of costs were collected as displayed in the
following table.

Source	Fee for Lead and Copper Analysis of Drinking Water	Citation

US EPA	$20 - $100	http://www.epa.gov/safewater/lead/leadfacts.html

NY State DOH	$15 - $50
http://www.health.state.ny.us/nysdoh/lead/leadwtr.htm

CWLTI 

(non profit in NC)	$24 – lead only

$30 lead and copper	http://www.leadtesting.org/orderonline.htm

Hometips.com	$35 – lead only	http://www.hometips.com/help/wat5.html

Fairfax Water	$35 per faucet	http://www.fcwa.org/water/lead.htm



The updated estimate of $36.34 per sample for lead and copper is well
within the range provided by the USEPA and the NY State Department of
Health.  It is also very close to the $35 that one system charges for
lead testing (Fairfax Water) and the estimate from a home advice website
from two national laboratories (National Testing Labs and Suburban Water
Testing).

	Based on OMB guidance in order to be consistent with estimates for
other drinking water rules, the June 1999 ICR assumes that all analysis
is conducted in-house for utilities, requiring that the commercial fee
be broken into its labor component and materials component.  The labor
required to analyze each sample is estimated at 1 hour, based on the use
of the ICP-MS (200.8) method.  The average technical labor rate for 1
hour of technical labor is estimated in the following table.

Size Category	Labor for 1 Hr

<= 100	$23.86 

101 to 500	$25.70 

501 to 3,300	$27.54 

3.3K-10K	$28.20 

10K-100K	$28.99 

>100K	$34.79 

Mean	$28.18 



The materials cost associated with analyzing a compliance sample for
lead and copper can then be estimated by subtracting the labor component
of $28.18 from the total fee of $36.34, for an estimate of $8.16
materials cost per sample.

Sample Reporting: Calculation of 90th Percentile

	To assess compliance with the LCR Action Levels, systems must calculate
the 90th percentile of the lead and copper samples.  Activities
associated with determining compliance include the following:

Collection of sampling results,

Validation that all appropriate samples are included,

Arrangement of samples by rank order, and

Determination of the 90th percentile value.

The burden to calculate the 90th percentile levels from monitoring
results is estimated as follows in the June 1999 ICR:

System Size	Burden Estimate

<= 100	0.5 hours

101-500	0.5 hours

501-10K	0.5 hours

10-100K	0.75 hours

>100K	1 hour



These estimates are also used in the 2004 ICR and, in the absence of new
information, have been applied in this analysis.

Sample Reporting: Reporting Results to State

Systems are required to report the results of the LCR compliance
monitoring to the State.  Activities associated with reporting results
to States include the following:

Assembly and organization of monitoring results and compliance
calculations, 

Completion of required certifications, and 

Preparation of the cover letter to the State.

The June 1999 ICR estimates that all systems will incur 1 hour to
conduct these activities related to reporting results to States.  The
materials cost for State reporting is the cost of one postage stamp --
$0.39.  These estimates are also used in the 2004 ICR and, in the
absence of new information, have been applied in this analysis.

Sample Reporting: Total

	The total labor associated with reporting compliance monitoring results
to the State, including the calculation of the 90th percentile, is
summarized in the following table.  An additional materials cost of
$0.39 is also applied.

System Size	Burden Estimate

<= 100	1.5 hours

101-500	1.5 hours

Appendix D-2: Systems changing treatment in response to upcoming
regulations

 In an effort to verify the reasonableness of the assumption that 2
percent of systems will report a treatment change or addition of a new
source each year, a review of the number of systems that are expected to
change treatment due to upcoming drinking water regulation was
conducted. Over the next several years, systems will be faced with new
regulatory requirements that could result in treatment changes,
including changes to comply with the already promulgated Arsenic Rule
and the upcoming Long Term 2 Surface Water Treatment Rule, the Stage 2
Disinfectants/Disinfection Byproducts Rule, and the Groundwater Rule. We
use estimates of the number of systems that are projected to change
treatments to comply with three Rules (Arsenic, LT2 and Stage 2) as a
reasonableness check on the assumption about the number of systems that
will submit treatment or sources changes for review under the LCR. 

Arsenic – 4,100 systems (Data source: Arsenic in Drinking Water EA,
pp. 6-25, 6-27;

LT2 –2,882 systems (Data source: USEPA, Office of Water, Economic
Analysis for the

Final Long Term 2 Enhanced Surface Water Treatment Rule, EPA
815-R-06-001, December 2005. Exhibit 6-1, page 6-3);

Stage 2 D/DBP – 2,261 systems (Data source: USEPA, Office of Water,
Economic Analysis for the Final Stage 2 Disinfectants and Disinfection
Byproducts Rule, EPA 815-R-05-010, December 2005, Exhibit ES-7a, page
ES-17).

Together, these regulatory requirements are estimated to cause 9,243
systems to institute a treatment change, although not all of these
treatment changes will impact corrosion control. The Stage 2 and LT2
treatment changes are projected to take place within a 6 year compliance
period for large systems (with the possibility of 2-year extension) and
8 years for small systems (with the possibility of 2-year extension)
according to page ES-5 of the Stage 2 EA and page ES-6 of the LT2 EA.
The period of compliance for the Arsenic rule is 5 years. Depending on
the range of years for compliance periods for the LT2 and Stage 2 Rules
(6-8 years), approximately 1,400 – 1,600 systems may change treatment,
although not all of these changes will impact corrosion control. 

To account for these expected treatment changes, and to account for
treatment changes unrelated to arsenic, LT2, and Stage 2 rule, EPA
assumed (based on the projected rule-related treatment changes and
expert judgment) that approximately 20% of the systems affected by the
LCR will institute a treatment change in the next ten years.  It is
assumed that these changes occur uniformly over that 10-year period, so
that approximately one-tenth of these systems (or 2 percent of the
total) institute a treatment change each year.  

Using the 2 percent estimate, 1,067 (53,372 X .02) systems each year
would report a treatment change or source addition and incur costs in
that year in States currently not covered by an explicit review and
approval program. The estimate for the number of systems is 552 if
States with a permitting or plan approval process are also excluded.

Appendix D-3: Regulatory Change III.D System Review Costs (4th Qtr
2006$)

 	High Estimate	Low Estimate

# CWS and NTNCWS Affected by Reg Change III.D1 Each Year:	1,067	1,067

Total System Burden (Hrs.)2	8,005.80	8,006

# CWS Affected by Reg Change III.D Each Year3	810	810

# CWS That Must Conduct an Engineering Study Each Year4	25.92	12.96

Annual Cost5	$765,083	$505,883



Notes:

1.  The number of CWS and NTNCWS affected by Regulatory Change III.D is
based on the USEPA Survey of States Questions on State Implementation of
Lead and Copper Rule (July 2004). Survey results show that 14 States
explicitly require review and approval of potential effects of treatment
changes on corrosion control.  53,372 systems in States other than these
14 States would be  affected by this Regulatory Change. It is assumed
that each year 2% of systems have a treatment or source change that
requires review and approval (per the 1999 ICR, page B-8).  Therefore
the number of systems to be affected by this regulatory change each year
is estimated to be 53,372 x 0.02 =  1,067 systems.

2.  It is assumed that all systems will each spend 8 hours to prepare a
submittal letter, coordinate with State, and participate in a meeting
with the State primacy agency. The current system of notification for
treatment changes requires a burden of 0.5 hour (per 1999 ICR) so this
is    deducted from the 8 hours for a total of 7.5 hours per system. The
burden assumption is based on consensus of expert panelists on 11.21.05.

3. The number of CWS affected by Reg Change III.D is based on survey
results from the USEPA Survey of States Questions on State
Implementation of the LCR (July 2004) as described in Notes 1 and 2. The
number of CWS for each State affected by Reg Change III.D was determined
using the USEPA "Factoids: Drinking Water and Groundwater Statistics for
2004". It is assumed that each year 

2% of systems have a treatment or source change that requires review and
approval (per the 1999 ICR, page B-8).  Therefore the most conservative
estimate is 40,499 CWS x 0.02 = 810 CWS and the conservative estimate is
21,080 CWS x 0.02 = 422 CWS.

4.  Assume that 10 to 20 percent of medium and large systems must
conduct an engineering study due to Reg Change III.D based on consensus
agreement of expert panelists on 11.21.05. Since 99 percent of NTNCWS
are small systems (serving <3,300 people), it is assumed that only
medium and large CWSs must conduct an engineering study.  Assume 16% of
CWS are medium or large systems based on the USEPA "Factoids: Drinking
Water and Groundwater Statistics for 2004". For the most conservative
estimate assume that 20% medium and large systems conduct an engineering
study.  For the conservative estimate, assume that 10% conduct
engineering studies.  Therefore, the most conservative estimate equals
810 CWS x 0.16 x 0.20 = 26 systems.  The conservative estimate equals
422 CWS x 0.16 x 0.10 = 7 systems.

5.  Annual cost is equal to the total system burden (hours) multiplied
by a labor rate of $30.81 per hr. (average of wage rates from SAIC
contract study, "Labor Costs for National Drinking Water Rules" (2003)
updated to 4th Qtr 2006 plus $20,000 for an engineering study for a
subset of medium and large CWS.

Notes:

1.  The number of systems affected by Regulatory Change III.D is based
on the USEPA Survey of States Questions on State Implementation of Lead
and Copper Rule (July 2004). Survey results show that 14 States
explicitly require review and approval of treatment changes.  53,372
systems in States other than these 14 States would be affected by this
Regulatory Change.  It is assumed that each year 2% of systems have a
treatment or source change that requires review and approval (per the
1999 ICR, page B-8).  Therefore the number of systems to be affected by
this regulatory change each year is estimated to be 53,372 x 0.02 = 
1,067 systems.

2. For the most conservative estimate, it is assumed that States spend 8
hours to review each system's data/reports, coordinate with system and
make approval decision and formalize with management. For the
conservative estimate, it is assumed that States spend 4 hours per
system for the same activities.  These estimates are based on a
consensus agreement of expert panelists on 11.21.05. The current  system
of notification for treatment changes requires a State burden of 0.5
hour (per 1999 ICR); therefore, the most conservative estimate for new
state burden is 7.5 hours and the conservative estimate is 3.5 hours per
system. 

3.  Use state labor rate of $43.52/hour (Source: Information Collection
Request for Contaminant Occurrence Data in Support of EPA's Second Six
Year Review of National Primary Drinking Water Regulations (August
2006)).

Appendix E

Derivation of Direct Costs for Regulatory Change III.E



Appendix E-1:  Derivation of the Number of Systems That Do Not Notify
Customers of Tap Monitoring Results (III.E)

	As part of EPA’s review of the Lead and Copper Rule, States and
primacy agencies were asked a variety of questions dealing with the
implementation of the LCR. Several questions dealt with the issue of
whether systems provide customers (i.e., homeowners or other drinking
water consumers) who participate in lead tap sampling with the results
of that sampling. The responses to these questions are used as a basis
for estimating how many systems currently provide lead sampling results
to customers and will therefore not incur additional costs due to
regulatory change III.E.

Primacy agencies were asked the following question:

“Although not required by Federal regulation, do systems provide
homeowners with lead sampling results derived from any volunteer
sampling program?  Does the state make any recommendations to public
water systems in this area?”

	We focused our analysis on answering three questions:

Are systems required to notify homeowners with lead sampling results
derived from any volunteer sampling program? 

Do States encourage systems to notify homeowners with lead sampling
results derived from any volunteer sampling program?

Do homeowners receive notification of lead sampling results derived from
any volunteer sampling program?

44 States indicated whether the notification of testing results to
households was required by State law. The response of each State is
summarized in Table E-1.

Wisconsin is the only State that currently requires systems to notify
households with lead sampling results derived from their home. This
regulation is formalized in 809.541(12) Wis. Adm. Code. Texas currently
requires systems to notify households if the sample from their house is
above the action limit.  Prior to 1993, Florida required systems to
notify households if the sample from their home was above action limit.
This requirement was terminated after the State realized that there was
no federal action requiring such notification.

Many States, however, encourage systems to notify homeowners of sampling
results, as summarized in Table 2. 52.4 percent of all States that
responded encourage systems to notify households with lead sampling
results derived from any volunteer sampling program. 10 States, 23.8
percent of all States that responded, encourage systems to notify
households for specific situations. For example, 7 States only encourage
systems to notify households if lead levels are greater than the action
limit (as indicated by “If Sample is > AL” in Table E-2). 3 States
only encourage systems to notify households if an occupant specifically
requests the sampling and/or results (as indicated by “If Results are
Requested” in Table E-3). 

In addition, many States are aware of at least some systems in the State
that notify homeowners at the current time, as summarized in Table E-3.
29 States indicated whether households are notified of testing results,
while 11 States did not have any data or knowledge indicating whether
households were notified of testing results.

The State responses to the three questions were evaluated to determine
the overall notification status for the State in Table E-4. The
categories for notification are as follows:

Required

Large systems only

Encouraged by State

If greater than Action Level

Upon request by homeowner

If greater than Action Level and upon request

Sometimes

If greater than 100 ppb

None

Unknown

For each of these categories, we assigned a percent of systems in that
State that notify customers, also shown in Table E-4. 

Required: 100 percent

Large systems only: 100 percent of large systems

Encouraged by State: 16 percent. This value was derived from Rogers
Diffusion of Innovation Theory that postulates that for a new technology
or practice, 3.5% percent of affected parties will be “innovators”
and 12.5% will be “early adopters” who will adopt a practice or
technology without being required.  We assume that this same principle
applies to the adoption of an encouraged, but not required, practice for
drinking water systems, such as notification of customers. 

If greater than Action Level: 10 percent

Upon request by homeowner: 5 percent

If greater than Action Level and upon request: 15 percent

Sometimes: 5 percent

If greater than 100 ppb: 1 percent

None: 0 percent

Unknown: 0 percent

We calculate the number of systems per State by size category that are
already notifying customers by multiplying these assumed percentages by
the number of systems. We estimate the number of systems not notified,
who would therefore incur costs under the new rule provision, by
subtracting the number of systems that notify from the total number of
systems. Table E-5 displays the number of systems that notify and that
do not notify by system size.

Notes:

1.  Number of CWS and NTNCWS systems per SDWIS/FED Data 2004. 

2.  Data source: USEPA Survey of States - Questions on State
Implementation of Lead and Copper Rule (July 2004).

3. The number of systems affected by Reg. Change III.E equals the total
number of CWS and NTNCWS systems (see Note 1) multiplied by the
percentage of systems that currently do not notify their customers (see
Note 2). For example, 89% of 13,766 CWSs serving <100 people do not
notify customers; therefore, these 12,252 (13,766 x 0.89) systems are
affected by Reg. Change III.E.

4.  Regulatory Change III.E will also affect systems that are affected
by regulatory change III.C that exceeded the lead action level while on
reduced monitoring and had to revert to standard monitoring, and do not
currently notify their customers of lead test results.  The number of
systems affected by regulatory change III.C is based on the number of
systems exceeding the lead action level as reported in the SDWIS Fed
data 2003.  The number of CWS and NTNCWS are listed separately in this
table because the NTNCWS have a different burden requirement.  NTNCWS
are not required to prepare notification letters for each sample but
provide general notification through bulletin board notices.  It is also
assumed that 91% of these systems are on reduced monitoring based on
USEPA Survey of States July 2004. 

5. For the subtotal of systems affected by Reg. Change III.E, it is
assumed that 9% of systems use a standard monitoring schedule with 6
monitoring events in 3 years or 2 monitoring events each year.  It is
also assumed that 91% of systems are on a reduced monitoring schedule
with 1 monitoring event in 3 years. In addition, systems affected by
Reg. Change III.C that are also affected by Reg. Change III.E use a
standard monitoring schedule with 2 monitoring events each year.(Source:
USEPA Survey of States - Questions on State Implementation of Lead and
Copper Rule. July 2004). For systems affected by Reg. Change III.C,
assume all systems have reverted to a standard monitoring schedule. 

6.  The number of customer notification letters on lead monitoring
results is based on the sampling schedule for standard and reduced
monitoring as summarized in Table 7.1.a.  It is assumed that one letter
is sent for each sampling site required by 40 CFR 141.86c.

7. For CWSs, assume burden of 1 hour per monitoring event for systems
serving <3,300 people.  For systems serving > 3,300 people, assume
burden of 1 hour per 20 letters  For NTNCWSs, assume 1 hour per
monitoring event for all system sizes.  Burden estimates based on
recommendations of Expert Review Panel (November 2005).

8. Wage rates from SAIC contract study, "Labor Costs for National
Drinking Water Rules (2003) updated to 4th Qtr 2006.

Derivation of Direct Costs for Regulatory Change III.G

Appendix F-1: Derivation of estimates for lead service line replacement
sampling

	Under the existing rule, systems that are replacing lead service lines
in response to an Action Level exceedance may sample lead levels from
lead service lines to determine if physical replacement is required. If
the sampled lead levels from an individual service line is below the
Action Level (15 ppb), that line would not have to be physically
replaced, but could be considered “replaced” towards meeting the
annual goal of 7 percent replacement. The sampling of lead service lines
associated with lead service line replacement activities is similar to
LCR compliance sampling in that tap samples from residential homes are
used. The service line samples will either require access to the house
or a separate set of instructions for taking the sample if sampling is
performed by the customer. In addition, sampling needs to be carried out
in a way to ensure that levels of lead in the service line (as opposed
to household plumbing) is measured. Often, the change in water
temperature is used to determine if the water is from the service line. 
However, in many climates, the temperature change approach may not work,
so additional time will be needed to determine the volume of water to
flush to reach the service line (determining the diameter and length of
the service line and household plumbing to estimate the volume of water
to flush to reach the service line). Systems incur costs to collect and
analyze these samples.

Sample Collection

	

	In order to collect drinking water samples from customer sites to
conduct monitoring for lead service line replacement, systems undertake
the following activities:

Notification of customers at locations targeted for lead service line
replacement,

Distribution of sample materials and instructions,

Coordination with customers during sampling to remind them and answer
questions,

Collection of samples from customer locations, and

Review of samples and validation that appropriate collection procedures
have been followed.

The labor required by systems to sample lead service lines for lead
content has been estimated previously by EPA. The June 1999 Information
Collection Request states that “Each sample will require a collection
burden of 2 hours…”  The estimate of 2.0 hours per sample for lead
and copper tap sampling collection is also used in the 2004 ICR and, in
the absence of new information, has been applied in this analysis.  It
should be noted that this estimate is slightly less (2.0 hours instead
of 2.5 hours) than the estimate of similar sampling to assess compliance
with the LCR.  Compliance sampling entails a different set of up-front
activities, including identification and recruitment of participants. 
Lead service line replacement up-front activities are a bit different in
mainly notifying customers of sampling and possible lead service line
replacement.  It is expected that less time is needed to recruit
participants for lead service line sampling as compared to LCR
compliance monitoring because the participant may receive a direct
benefit (removal of lead service line if lead level is greater than 15
ppb).  These differences in up front activities offer a possible
explanation for the difference in collection burden between LCR
compliance monitoring and lead service line sampling.

Sample Analysis

	Previous documents estimated the cost to analyze a water sample for
lead content as being half the cost to analyze a sample for both lead
and copper content.  The method most commonly used at the current time
(ICP-MS (200.8) method) provides estimates for both lead and copper. 
Therefore, this analysis assumes that the cost to analyze a sample for
only lead is the same as the cost to analyze for both lead and copper.

The cost to analyze a compliance sample for lead is based on the fee
charged by certified commercial laboratories.  This fee includes both
the cost of labor and materials.  The June 1999 ICR assumed a commercial
fee of $30 to analyze a sample for lead and copper.  Updated to current
dollars (4th Qtr 2006), the fee is estimated at $36.34 per sample.  To
validate that the updated analysis fee is reasonable, publicly available
estimates of costs were collected as displayed in the following table.

Source	Fee for Lead and Copper Analysis of Drinking Water	Citation

US EPA	$20 - $100	http://www.epa.gov/safewater/lead/leadfacts.html

NY State DOH	$15 - $50
http://www.health.state.ny.us/nysdoh/lead/leadwtr.htm

CWLTI 

(non profit in NC)	$24 – lead only

$30 lead and copper	http://www.leadtesting.org/orderonline.htm

Hometips.com	$35 – lead only	http://www.hometips.com/help/wat5.html

Fairfax Water	$35 per faucet	http://www.fcwa.org/water/lead.htm



The updated estimate of $36.34 per sample for lead and copper is well
within the range provided by the USEPA and the NY State Department of
Health.  It is also very close to the $35 that one utility charges for
lead testing (Fairfax Water) and the estimate from a home advice website
from two national laboratories (National Testing Labs and Suburban Water
Testing).

	Based on OMB guidance in order to be consistent with estimates for
other drinking water rules, the June 1999 ICR assumes that all analysis
is conducted in-house for utilities, requiring that the commercial fee
be broken into its labor component and materials component.  The labor
required to analyze each sample is estimated at 1 hour, based on the use
of the ICP-MS (200.8) method.  The average labor rate for 1 hour of
labor is estimated in the following table.

Size Category	Labor for 1 Hr

<= 100	$23.86 

101 to 500	$25.70 

501 to 3,300	$27.54 

3.3K-10K	$28.20 

10K-100K	$28.99 

>100K	$34.79 

Mean	$28.18 



The materials cost associated with analyzing a compliance sample for
lead can then be estimated by subtracting the labor component of $28.18
from the total fee of $36.34 for an estimate of $8.16 materials cost per
sample.

Notes:

1.  Systems that have been required to conduct a lead service line
replacement program may potentially be affected by Reg. Change III.G if
they discontinue the program, then later re-exceed the lead action
level. The number of systems was estimated based on survey responses
from the USEPA Survey of States Questions on State Implementation of
Lead and Copper Rule (July 2004).Six states indicated the specific
number of systems that have been required to initiate LSL replacement
programs (total of 28 systems).  Five other states indicated that they
had systems that were required to have LSL programs but did not indicate
the specific number of systems.  For these 5 States, it is assumed that
each State has 5 systems with LSL programs required by State, for a
total of 25 systems. One system is added for DCWASA. The total number of
systems affected by Reg. Change III.G is assumed to be 28+25+1= 54
systems.

2.  Assume 1.4% systems re-exceed lead action level and are required to
continue LSL replacement program (data source:   HYPERLINK
"http://www.epa.gov/safewater.lcrmr"  www.epa.gov/safewater.lcrmr )
Assumption is based on current exceedance rate for lead action level by
medium and large systems.

3.  If a system re-exceeds the lead action level, samples must be
collected from each lead service line previously deemed to be replaced
through testing. The number of LSLs per system that have previously been
replaced through testing is estimated based on a utility survey
completed by Black and Veatch in 

July 2005.  Twenty-six utilities reported that 558,135 LSLs in 1992 or
21,467 LSLs per system. Assuming each utility conducts LSL replacements
at a rate of 7% per year or over 15 years, this equals 21,467 divided by
15 or 1,431 LSLs per system per year 
(www.epa.gov/safewater/lcrmr/pdfs/summary_lcmr_review_lead_line_replacem
ent_workshop_10-26-04.pdf).

4.  Assume that a system conducts a LSL replacement program for 15 years
upon initial exceedance of the lead action level based on LCR
requirements. The number of samples in the sampling pool is equal to the
number of systems that re-exceed the lead AL, x (annual # samples per
system) x 15 years.

5.  Assume the utility replaces 24% of LSLs and tests-out the remaining
76% based on data from DCWASA (2003). The number of samples that needs
to be retested equals the number of samples in the sampling pool x 76%.

6.  Assume burden is 3 hours for sample collection and analysis as
described in Appendix F-1.  Use system labor rate of $30.81 per hour
(average of wage rates from SAIC contract study, "Labor Costs for
National Drinking Water Rules" (2003) updated to 4th Qtr 2006.

7.  Use average O&M cost per sample $8.16as described in Appendix F-1.

8.  Assume the systems conduct retesting over a 15 year period (based on
LCR requirements for LSL replacement programs).

501 and 3,300 people.  Assume 0.5 hours savings for each of the 184
systems in this size category (Refer to Table 1 above). The total
reduction in burden equals 92 hours (184 * 0.5 hours). 

3. For customer notification, States need to review additional language
for 994 systems that are estimated to exceed the LAL at an estimated 20
minutes per system. The total new burden to States equals 328 hours (994
systems * 0.33 hours).The net new burden to States equals 328 hours
minus 92 hours equals 236 hours.

5. For consultation on activities, review of cover content, discussion
of alternative mechanisms, and discussion of extending deadlines, States
need to review activities with CWSs that exceed the LAL once per year at
2 hours per year.

6. For review and filing of letter from CWSs that exceed the LAL
self-certifying that additional PE activities have taken place, States
will require .10 hours per system per year, based on similar activity

Appendix I

Uncertainty Analysis for III.F(b)(2) Activities

Uncertainty Analysis for Choosing Activities III.F(b)(2)(i)-(viii)

Due to the uncertainty in predicting the selection of activities (i)
through (viii) by systems to comply with Regulatory Change III.F(b)(2),
three alternative selection scenarios have been developed to illustrate
the potential range of costs.  The three scenarios represent predicted
activity selection based on different considerations:

Cost as the sole consideration

Cost as a primary consideration, with other factors as a secondary
considerations

Other factors as a primary consideration.

Cost as the sole consideration

	To simulate a situation in which cost minimization is the sole criteria
for choosing activities, this analysis assumes that systems will choose
the three least costly activities.  The average cost per system is
calculated as the average of the three least costly activities.  The
selection of activities and resulting average costs are presented in
Table I-1.

	Although cost is an important consideration, it is not usually the sole
consideration.  Systems may choose more costly activities to reach a
broader range of audiences in a more effective manner.  To simulate a
situation in which cost is a primary , but not the sole, factor for
choosing activities, this analysis assumes that less costly activities
are more likely to be chosen and the more costly activities will be
chosen, but at a lower rate.  For each system size category, the
activities are characterized as “more likely”, “likely”, and
“unlikely” to be chosen based on the cost per system.  The two
lowest cost activities are classified as “more likely”, the two
highest cost activities are classified as “unlikely” and the middle
four activities are classified as “likely”.  To calculate a weighted
average cost per system given the activity choices, more likely
activities are assigned a probability of 25 percent (i.e., the activity
is chosen 25 percent of the time), likely activities are assigned a
probability of 10 percent, and the unlikely activities are assigned a
value of 5 percent.  The resulting selection of activities and weighted
average cost per system are presented in Table I-2.

	The third scenario reflects a best guess estimate of activity choices
if cost were not a factor.  The members of the NDWAC working group were
asked to rank the activities on a scale of 1-8, with 1 representing
activities most likely to be chosen and 8 for activities least likely to
be chosen within each system size category.  The NDWAC working group
members were not provided information on the cost per system, so their
responses reflect considerations other than cost.  Due to time
constraints, only a limited number of responses were received.  The
rankings were averaged across the responses, so that each activity had
an average ranking.  The activities with the two lowest average ranking
were characterized as most likely and assigned a probability of 25
percent.  The activities with the two highest average ranking were
considered unlikely and assigned a probability of 5 percent.  All other
activities were considered likely and assigned a probability of 10
percent.  The resulting activity choices and weighted average cost per
system are displayed in Table I-3.

	Table I-4 summarizes the weighted average cost per system for each
system size and for each of the three scenarios.  Across all system
sizes, the weighted average cost per system is lowest for the scenario
in which activities are chosen with cost as the only consideration and
highest when other factors are the primary consideration. Table I-4 also
displays the total costs for III.F(b)(2) for each scenario.  It should
be noted that the total cost under the highest of the three scenarios,
the other factors as the primary consideration scenario at $276,952 is
lower than the cost of III.F(b)(2) reported in the main section of the
Economic Analysis ($292,700) based on an un-weighted average of all
activities.  Thus, the costs reported in the Economic Analysis may
overstate actual costs that will be experienced.

This document provides an estimate of community water system (CWS)
revenue for systems serving 10,000 or fewer people.  The estimates are
based on two sources of information:  EPA’s 2000 CWS Survey and the
2002 Census of Governments fielded by the Census Bureau.  CWS revenue
and municipal government revenue for publicly owned CWSs are combined to
provide an estimate of the total resources available to CWSs in the
10,000 or fewer population size category. 

CWS revenue comes from three sources:  

Water sales.  This revenue is generated by the sale of water to
customers and is usually based on a rate charged per unit of water sold.


Water-related revenue.  This revenue consists of transfers from
municipal government general funds, fees, penalties, or other charges
related to the provision of water, but not tied directly to the sale of
water.  Note:  Water sales and water-related revenue together are
referred to as “water revenue.”  

Non-water revenue.  Systems also may have non-water revenue.  For
example, combined drinking water and wastewater systems may have revenue
from sewerage charges. These sources of revenue are excluded from this
analysis, with two important exceptions.  Ancillary systems – small
privately owned systems (generally, serving populations of 3,300 or
fewer people) that provide water as an essential part of another
business – will have revenue from their primary business and often do
not report any water revenue at all. Municipal governments may rely on
general revenue in addition to or in lieu of water revenue to finance
their systems.  In many cases, these sources of revenue are available to
systems to support their operations; therefore, they must be included to
fully account for the resources available to water systems.  

Exhibit 1 reports revenue of systems by the source of revenue.  The
estimates are based on data from the 2000 Community Water System Survey
(CWSS) and the 2002 Census of Governments.  For each source, it reports
the average revenue for systems with that source of revenue in the first
column of numbers; in other words, it excludes systems with zero revenue
from that source.  The second column reports the number of systems in
the nation with that source of revenue.  The final column of numbers
reports the number of observations in the sample on which the estimates
are based.  (Because the exhibit excludes systems that report zero
revenue from each source, the revenue figures from each source cannot be
summed to reach the total.  See below for a more detailed explanation)

Many systems do not have each source of revenue.  Exhibit 2 reports the
percentage of systems that reported positive revenue from each revenue
source.  According to the CWSS, approximately 82 percent of systems
reported revenue from water sales.  Less than 3 percent reported
transfers from the general fund (the percentage is higher for publicly
owned systems), and 51 percent reported other water-related revenue. 
Overall, 80 percent of systems reported revenue from water sales or
water related revenue.  

Judging from the percentage of systems reporting, it would appear that
fewer systems reported positive water revenue than reported positive
water sales.  This apparent contradiction is due to different response
rates to the various revenue questions in the survey.  Some systems
reported water sales, but could not provide their water-related revenue.
 Total water revenue for these systems therefore was not available and
these systems are excluded from the estimate of the percentage of
systems reporting positive total water revenue.  Other systems reported
their total water revenue, but could not distinguish between water sales
and other water revenue.  They are included in the estimate of the
percentage of systems that reported positive water revenue but are not
included in any of the components.  If we limit the analysis to systems
that provided data on all revenue components, approximately 81 percent
of systems reported positive water revenue.  Less than 1 percent of
these systems reported zero water sales revenue.  (In other words, they
relied solely on water-related revenue.)

Approximately 20 percent of small systems do not charge directly for
water, either through water sales or water-related charges.  Among some
subclasses of systems, the percentage of systems that do not charge for
water is substantially higher.  For example, according to the CWSS, 92
percent of ancillary systems reported zero water revenue.  Systems
without water revenue may rely – directly or otherwise – on other
sources of revenue.  

Sources of Data 

The 2000 CWSS collects data on all three sources of revenue.  It asks
each system for water sales and water-related revenue.  The survey also
asks ancillary systems to report non-water related revenue because many
of these systems do not charge directly for water.  (The survey does not
ask for non-water revenue of other systems.)  Because so many ancillary
systems do not charge for water, estimates of the resources available to
these systems include survey data from their main source of revenue.    

The 2000 CWSS collected data from 104 ancillary systems.  The response
rate on the question about non-water revenue was relatively low;
approximately 50 percent of these systems provided data on their
non-water revenue.  It is not clear whether this non-response introduces
bias into the estimate of non-water revenue of ancillary systems.  The
revenue reported also varies greatly.  

While some of the ancillary systems are small water systems, often
mobile home parks, they also may be relatively large companies and their
water revenue may be a very small part of their total revenue.  Other
ancillary systems may have very limited revenue from their other
sources.  Mobile home parks, for example, may fund all their expenses
– water-related and other wise – from pad fees that may be quite
modest.  The estimates of non-water revenue of ancillary systems are
therefore not precise.  

Approximately 6 percent of publicly owned systems serving 10,000 or
fewer people report zero water revenue in the survey; nearly half of
publicly owned systems serving 100 or fewer people report zero water
revenue.  For these systems to operate, they must have other sources of
revenue that are not included in the survey.  Even systems run as public
enterprise funds may have access to funds from the general fund of their
municipality.  Therefore, estimates of water revenue do not fully
describe the financial resources available to these systems.  To account
for this potential resource of publicly owned systems, therefore, data
from the US Census Bureau’s 2002 Census of Governments were used to
estimate total municipal revenue of cities and towns that provide water
to 10,000 or fewer people.  Non-water revenue of municipalities is the
difference between the total revenue of the municipality and the revenue
generated by its water system.  Many municipalities transfer money from
their general funds to their water systems.  To avoid double counting
these transfers, they are excluded from the estimate of municipal
non-water revenue and included as part of water revenue.  

Basis of the Estimates

The 2000 CWSS sample is used to calculate the average water system
revenue estimates.  The estimates are weighted by the inverse of the
sampling probabilities, corrected for overall non-response.  Four
systems were dropped from the analysis because they were outliers
(resorts or other special cases).  If they had been included, the
revenue estimates would have been higher. 

Not every system reported revenue from each source in the CWSS.  For
example, of the 610 systems that reported revenue from any source, 54
did not report positive water sales revenue.  These systems are excluded
from the calculation of average water sales revenue.  Therefore, total
revenue is not equal to the sum of revenue from each source.  Before we
can sum the components, we must account for systems that did not report
revenue from an individual revenue source.  

Exhibit 3 summarizes how water revenues are calculated based on the
average revenue reported for each source and the percentage of systems
with each source of revenue.  (Details may not sum to the total due to
rounding.) The calculation can be divided into two parts.  The first
part is shown in lines A through I.  We sum the sources of revenue,
adjusting for systems that reported zero revenue from each source.  For
example, the average water sales revenue of systems with water sales is
$191,252 (line A).  Approximately 82 percent of systems reported
positive water sales (line B).  The average water sales revenue of all
systems, including those reporting zero water sales revenue, is
$156,538, or line A multiplied by line B.  This calculation is repeated
for general fund transfers (lines D through F) and other water-related
revenue (lines (G through I).  The sum of these products is $176,658,
and is shown in line J (i.e., the sum of lines C, F, and I).  

The second part of the calculation is shown in lines J through N in
Exhibit 3.  We make three adjustments to the sum shown in line J. 
First, many systems reported their water sales revenue but not the other
components of their water revenue; therefore, their total revenue is
unknown.  The water sales revenue of these systems ($1,363, on line K)
must be removed from the total in line J.  Second, some systems reported
total water revenue, but could not divide their revenue by source.  The
average revenue not associated with an individual source is $222 (line
L).  This must be added to the total on line J.  Finally, the
approximately 20 percent of systems that did not report water revenue
(or line M) must be removed to estimate the average water revenue of
systems with positive water revenue.  Line N reports the adjusted total
water revenue of systems with water revenue.  

As we cannot distinguish between systems that did not respond to a
revenue question and systems who, in fact, have zero revenue to report,
we may be over-estimating the percentage of systems with no revenue for
any given revenue category.  Thus, in calculating the average revenue
for all small systems, we may be underestimating revenue by assuming
that a non-response equals a zero.   

The non-water revenue of publicly owned systems is based on the Bureau
of the Census estimate of total revenue of municipalities with fewer
than 10,000 people.  Exhibit 4 shows how we estimate the non-water
system revenue of municipalities, net of transfers to water systems.

According to the 2002 Census of Governments, there were 16,745
municipalities (line P) with populations under 10,000 in 2002.  The
total revenue of these municipalities was $34,944,647,000 in 2002 (line
O).  Average revenue per municipality is line O divided by line P, or
$2,086,871 (line Q).  Based on the US Bureau of Labor Statistics,
Consumer Price Index, the cumulative change in consumer prices between
2002 and 2006 was 13.8 percent (line R). The inflation-adjusted estimate
is $2,375,157, shown in line S.  According to the CWSS, water-system
revenue of publicly owned systems was $307,127 (line T).  Municipal
non-water-system revenue is line S minus line T, or $2,068,030 (line U).
 

Total revenue is a weighted average of system revenue and non-system
revenue.  The calculation is shown in Exhibit 5.  We assume that
privately owned systems that provide water as an essential part of
another business have non-water revenue.  According to the CWSS, average
non-water revenue for systems that report it is $5,843,880 (Line X). 
The CWSS reports that 16.3 percent of systems have this non-water
revenue (line Y).  Average non-water system revenue, including systems
with no revenue from this source, is the product of line W and X, or
$953,489 (line Z).

While publicly owned systems do not have this source of revenue, they do
have access to general fund revenue of their municipalities. 
Non-water-related revenue of municipalities is $2,068,030 (line AA). 
According to the CWSS, 49.2 percent of systems serving 10,000 or fewer
people are publicly owned (line AB).  Average municipal revenue,
including systems with no revenue from this source, is $1,017,332 (line
AC).  Total revenue is the sum of water revenue (line W) and the two
sources of non-water revenue (lines Z and AC), or $2,166,712.  

Conclusions

The average revenue available to small systems serving 10,000 or fewer
people is $2,166,712.  This estimate includes revenue from all sources. 
This estimate includes non-water business and government revenue that
will be used for purposes other than financing the operations of the
water system.  But it provides the best estimate of the financial
situation of these water systems.

Efforts to estimate the resources available to small water systems are
complicated by several factors.  First, there are few sources of data on
small systems.  The CWSS is one of the only surveys to systematically
collect data on small system finance.  Its focus is system operations
and finance, so it does not collect information about non-water system
finance that would inform this analysis.  The Census of Government data
fill some of the gaps and help portray a complete picture of small
system finance.  

Second, small systems are a relatively diverse group that finances its
operations many different ways.  Some charge directly for water, but
many do not.  For example, a homeowners’ association may provide water
as one of its services, but it may not charge its members a separate
water fee; rather, it pays its water-related expenses out of general
fees its charges its members.  A small town may pay for water services
out of general fund revenue and not charge its residents for water.  The
water revenue, as we define it, is in fact zero in both cases.  But both
the homeowners’ association and the small town have resources to pay
for repairs and improvements to their water system.  Other demands are
placed on these resources, so further analysis is required to determine
whether those resources are sufficient to meet the needs of the water
system.  

Finally, the data that are available on small system finances are often
incomplete.  This is due, in part, to the relative complexity of small
system finance.  Systems may not respond to financial questions because
it is difficult to distinguish water- from non-water-revenue.  As shown
in Exhibit 2, some systems provided data on some sources of revenue but
not others.  To produce the best estimates, we use all the data
available for each question rather than limiting the analysis to only
those systems that answered all the questions.  These estimates provide
the best estimates available of the resources available to small
systems.

  The Bureau of Labor Statistics has discontinued calculating the
Employment Cost Index by SIC code classifications (electric, gas and
sanitary services).  The comparable NAICS classification is for
utilities.  Also, BLS changed the base year for calculating the index
(Dec 2005 = 1.00).  The change in series classification and index year
does not result in an appreciable difference in the updating.  For
example, the update factor from 2001 to 2003 used in the exhibit is 1.07
either using SIC or NAICS for the time period.
