ENVIRONMENTAL PROTECTION AGENCY

NSPS for Industrial-Commercial-Institutional Steam Generating Units (40
CFR part 60, subpart Db) (Renewal)

1.  Identification of the Information Collection

	1(a)  Title of the Information Collection

	NSPS for Industrial-Commercial-Institutional Steam Generating Units (40
CFR part 60, subpart Db)

	1(b)  Short Characterization/Abstract

 	The New Source Performance Standards (NSPS), for the regulations
published at 40 CFR part 60, subpart Db for the pollutant sulfur dioxide
(SO2) were proposed on June 19, 1986, and promulgated on December 16,
1987.  These regulations, amended on February 27, 2006, apply to
industrial-commercial-institutional steam generating units (boilers)
that commenced construction, modification, or reconstruction after June
19, 1984, and that have a heat input capacity from fuels combusted in
the unit of greater than 29 MW (100 million Btu/hour).  This information
is being collected to assure compliance with 40 CFR part 60, subpart Db.

	In general, all NSPS standards require initial notifications,
performance tests, and periodic reports.  Owners or operators are also
required to maintain records of the occurrence and duration of any
startup, shutdown, or malfunction in the operation of an affected
facility, or any period during which the monitoring system is
inoperative.  These notifications, reports, and records are essential in
determining compliance, and are required of all sources subject to NSPS.

	Any owner or operator subject to the provisions of this part shall
maintain a file of these measurements, and retain the file for at least
two years following the date of such measurements, maintenance reports,
and records.  All reports are sent to the delegated state or local
authority.  In the event that there is no such delegated authority, the
reports are sent directly to the United States Environmental Protection
Agency (EPA) regional office.

Size of the Regulated Community

	In a study from 1979, EPA modeled the total capacity of U.S.
industrial/commercial boilers for 1980, 1985 and 2000, for boilers with
capacities greater than 29 MW (100 million BTU/hour) (“Population and
Characteristics of Industrial/Commercial Boilers in the United States
(U.S.) from 1979"; EPA Number PB80 - 150881).

	This model shows an increase of 4,139 new industrial/commercial boilers
between 1985 and 2000 with capacities greater than 29 MW (100 million
BTU/hour), and these would be subject to NSPS Db.  Therefore, according
to this model there should be approximately 4,139 steam generating units
(or boilers) currently subject to NSPS subpart Db.  Assuming one boiler
per facility, the number of facilities subject to NSPS subpart Db would
be 4,139.

	However, during the nitrogen oxide (NOx) NSPS revision, information on
industrial boilers subject to NSPS Db was obtained from three sources: a
best available technology/ lowest achievable emission rate database
search; copies of permits obtained from EPA regional offices; and
telephone contacts with EPA regions, state agencies, and boiler vendors.
 Based on the information obtained, as of 1995 only 45 NSPS Db boilers
were identified.  Since NSPS Db was in affect for ten years in 1995, 45
boilers is probably a low number and model projects indicate that it may
be far from the true regulated universe for 1995.  The estimated number
of boilers projected for the year 2000 is 4,139, using energy
consumption as the basis for the calculation.  The previous Information
Collection Response (ICR) estimated 957 facilities subject to NSPS Db.

	During the NOx NSPS revision mentioned above, an analysis was conducted
to determine the projected growth of new industrial boilers over the
period between 1996 to 2000.  This analysis showed that the growth rate
would be 76 new industrial boilers per year.  Therefore, using the
estimate from the previous ICR of 957 and assuming a growth rate of 76
new industrial boilers per year over the three-year period since the
last ICR.  The 76 new boilers per year would sum to 228 new industrial
boilers.  Assuming one boiler per facility this would come out to 228
new NSPS Db facilities added to the estimated number from the last ICR
submittal (957) for a total of 1,185 NSPS Db facilities estimated for
this ICR.

Growth Rate for the Next Three Years

	In the Industrial Boiler   SEQ CHAPTER \h \r 1 Maximum Achievable
Control Technology (MACT) rulemaking, a projection of new industrial,
commercial, and institutional boilers was performed for economic
analysis in October, 2002.  This analysis showed that 134 industrial,
commercial, and institutional boilers would become subject to NSPS
subpart Db over the next three years (or 45 per year).  This is the most
recent growth projection for these facilities.

	Therefore, this ICR is estimating that approximately 1,185 sources are
currently subject to the regulation, and it is estimated that an
additional 45 sources per year will become subject to the regulation in
the next three years.

	The Office of Management and Budget (OMB) approved the currently active
ICR without any “Terms of Clearance.”

2.  Need for and Use of the Collection

	2(a)  Need/Authority for the Collection

	The EPA is charged under section 111 of the Clean Air Act (CAA), as
amended, to establish standards of performance for new stationary
sources that reflect: 

. . . application of the best technological system of continuous
emissions reduction which (taking into consideration the cost of
achieving such emissions reduction, or any non-air quality health and
environmental impact and energy requirements) the Administrator
determines has been adequately demonstrated.  Section 111(a)(l)

The Agency refers to this charge as selecting the best demonstrated
technology (BDT).  Section 111 also requires that the Administrator
review and, if appropriate, revise such standards every four years.

	In addition, section 114(a) states that the Administrator may require
any owner or operator subject to any requirement of this Act to: 

(A) Establish and maintain such records; (B) make such reports; (C)
install, use, and maintain such monitoring equipment, and use such audit
procedures, or methods; (D) sample such emissions (in accordance with
such procedures or methods, at such locations, at such intervals, during
such periods, and in such manner as the Administrator shall prescribe);
(E) keep records on control equipment parameters, production variables
or other indirect data when direct monitoring of emissions is
impractical; (F) submit compliance certifications in accordance with
Section 114(a)(3); and (G) provide such other information as the
Administrator may reasonably require.

	In the Administrator's judgment, SO2, particulate matter (PM), and NOx
emissions from Industrial-Commercial-Institutional Steam Generating
units cause or contribute to air pollution that may reasonably be
anticipated to endanger public health, or welfare.  Therefore, the NSPS
were promulgated for this source category at 40 CFR part 60, subpart Db.

	2(b)  Practical Utility/Users of the Data

	The control of emissions of SO2, PM, and NOx from
Industrial-Commercial-Institutional Steam Generating units requires not
only the installation of properly designed equipment, but also the
operation and maintenance of that equipment.  Emissions of SO2, PM, and
NOx from Industrial-Commercial-Institutional Steam Generating units are
the result of operation of the affected facilities.  The subject
standards are achieved by the capture and/or reduction of SO2, PM, and
NOx emissions using control technologies such as sorbent injection
technologies and wet and dry scrubbers for SO2; cyclones, electrostatic
precipitators, and fabric filters for PM; and low NOx burners and
selective catalytic or noncatalytic reduction technologies for NOx.  The
notifications required in the applicable regulations are used to inform
the Agency, or delegated authority, when a source becomes subject to the
requirements of the regulations.  The reviewing authority may then
inspect the source to check if the pollution control devices are
properly installed and operated and the regulations are being met. 
Performance test reports are needed as these are the Agency's record of
a source's initial capability to comply with the emission standards, and
serve as a record of the operating conditions under which compliance was
achieved.  The semiannual reports are used for problem identification,
as a check on source operation and maintenance, and for compliance
determinations.  The information generated by the monitoring,
recordkeeping and reporting requirements described in this ICR is used
by the Agency to ensure that facilities affected by the NSPS continue to
operate the control equipment and achieve compliance with the
regulation.  Adequate monitoring, recordkeeping, and reporting are
necessary to ensure compliance with the applicable regulations, as
required by the Clean Air Act.  The information collected from
recordkeeping and reporting requirements also is used for targeting
inspections, and is of sufficient quality to be used as evidence in
court.

3.  Nonduplication, Consultations, and Other Collection Criteria

	The requested recordkeeping and reporting are required under 40 CFR
part 60, subpart Db.

	3(a)  Nonduplication

	 If the subject standards have not been delegated, the information is
sent directly to the appropriate EPA regional office.  Otherwise, the
information is sent directly to the delegated state or local agency.  If
a state, or local agency has adopted its own similar standards to
implement the Federal standards, a copy of the report submitted to the
state or local agency can be sent to the Administrator in lieu of the
report required by the Federal standards.  Therefore, no duplication
exists.

	3(b)  Public Notice Required Prior to ICR Submission to OMB

	An announcement of a public comment period for the renewal of this ICR
was published in the Federal Register on June 21, 2006.  No comments
were received on the burden published in the Federal Register.

	3(c)  Consultations

		

	  It is our policy to review carefully any comments received since the
last ICR renewal, including those submitted in response to the first
Federal Register notice, and respond appropriately.  In this case, no
comments were received.  To determine the size of the regulated
community and the rate of industry growth, the EPA Office of Air Quality
Planning and Standards was consulted.  The Agency’s internal industry
experts have been consulted.  The Agency’s internal data sources and
projections of industry growth over the next three years also have been
considered.

	Another source of information was the information provided by the
industry.  Information provided in the industry reports is located in
the EPA’s AFS (Air Facility Subsystem) database.  Approximately 1230
respondents are currently subject to the regulation.

It should be noted that the industry trade association(s) and other
interested parties were provided an opportunity to comment on the burden
associated with the standard as it was being developed, and the standard
has been previously reviewed to determine the minimum information needed
for compliance purposes.

	3(d)  Effects of Less Frequent Collection

	Less frequent information collection would decrease the margin of
assurance that facilities are continuing to meet the standards. 
Requirements for information gathering and recordkeeping are useful
techniques to ensure that good operation and maintenance practices are
applied and emission limitations are met.  If the information required
by these standards was collected less frequently, the likelihood of
detecting poor operation and maintenance of control equipment and
noncompliance would decrease.

	3(e)  General Guidelines

	None of these reporting or recordkeeping requirements violates any of
the regulations established by OMB at 5 CFR 1320.5.

	3(f)  Confidentiality

	The required information has been determined not to be confidential. 
However, any information submitted to the Agency for which a claim of
confidentiality is made will be safeguarded according to the Agency
policies set forth in Title 40, Chapter 1, part 2, subpart B -
Confidentiality of Business Information (see 40 CFR 2; 41 FR 36902,
September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR
42251, September 20, 1978; 44 FR 17674, March 23, 1979).

	3(g)  Sensitive Questions

	None of the reporting or recordkeeping requirements contains sensitive
questions.

	

4.  The Respondents and the Information Requested

	4(a)  Respondents/SIC Codes

Characterization and Classification of Boilers and Boiler-Related
Industries

	Industrial-commercial-institutional boilers (also known as steam
generating units) are classified by type, fuel, and method of
construction.  The three main types are cast iron, fire tube, and water
tube.  These three categories of boilers are designed and manufactured
to meet specific applications and site requirements.  Unit size, design
pressure and temperature all depend on boiler application.  Each boiler
type may burn coal , oil, or natural gas, and increasingly are being
designed to burn more than one fuel type.

	All boilers subject to NSPS subpart Db are water tubed boilers.  Water
tubed boilers are used in a variety of applications ranging from
supplying large amounts of process steam to providing space heat for
industrial facilities, or commercial buildings.  Water tubed boilers are
fueled by coal, 25 percent; oil, 32 percent, and natural gas, 43
percent.  Process steam accounts for the largest use of fuel to fire
boilers, using about one third of all industrial fuel.

	The following industries use water tubed boilers with capacities
greater than 29 MW (100 mmBtu/hr).  In EPA studies, energy usage was
used to estimate the potential for industry boiler usage.  The chemical
and paper industries use the most energy accounting for about a third of
all U.S. industrial fuel usage.  Petroleum refineries, steel and
aluminum manufacturers, and food processing industries use most of the
remainder of industrial fuel.  Other industries using smaller, but
significant amounts of fuel are the textiles, lumber, and rubber
manufacturers, and metal fabrication and transportation industries.  The
other two industries that would be expected to have boilers large enough
to be subject to NSPS subpart Db are office and shopping center heating
and boiler rentals.

	The respondents to the recordkeeping and reporting requirements are
facilities subject to NSPS subpart Db that commenced construction,
modification, or reconstruction after June 19, 1984, and that have a
heat input capacity from fuels combusted in the steam generating unit of
greater than 29 MW (100 mmBtu/hr).

5.  The Information Collected: Agency Activities, Collection
Methodology, and Information Management

	5(a)  Agency Activities

	EPA conducts the following activities in connection with the
acquisition, analysis, storage, and distribution of the required
information.

Agency Activities

Review notifications and reports, including performance test reports,
and excess emissions reports, required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Air Facility Subsystem (AFS)
database.



	5(b)  Collection Methodology and Management

	Following notification of startup, the reviewing authority might
inspect the source to determine whether the pollution control devices
are properly installed and operated.  Performance test reports are used
by the Agency to discern a source’s initial capability to comply with
the emission standard.  Data and records maintained by the respondents
are tabulated and published for use in compliance and enforcement
programs.  The semiannual reports are used for problem identification,
as a check on source operation and maintenance, and for compliance
determinations.

	Information contained in the reports is entered into AFS which is
operated and maintained by EPA's Office of Air Quality Planning and
Standards.  AFS is EPA’s database for the collection, maintenance, and
retrieval of compliance and annual emission inventory data for over
100,000 industrial and government-owned facilities.  EPA uses AFS for
tracking air pollution compliance and enforcement by local and state
regulatory agencies, EPA regional offices, and EPA headquarters.  EPA
and its delegated authorities can edit, store, retrieve, and analyze the
data.  The records required by this regulation must be retained by the
owner or operator for two years.

	5(c)  Small Entity Flexibility

	

	There are no small businesses affected by this regulation.

	5(d)  Collection Schedule

	The specific frequency for each information collection activity within
this request is shown in Table 2: Average Annual EPA Resource
Requirement for Fossil Fuel Fired Steam Generating Units/ NSPS subpart
Db.

6.  Estimating the Burden and Cost of the Collection

	Table 1 documents the computation of individual burdens for the
recordkeeping and reporting requirements applicable to the industry for
the subpart included in this ICR.  The individual burdens are expressed
under standardized headings believed to be consistent with the concept
of burden under the Paperwork Reduction Act.  Where appropriate,
specific tasks and major assumptions have been identified.  Responses to
this information collection are mandatory.

	

	The 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.

	6(a)  Estimating Respondent Burden

	The average annual burden to industry over the next three years from
these recordkeeping and reporting requirements is estimated to be
591,389 person-hours (“Total annual person hours” from Table 1). 
These hours are based on Agency studies and background documents from
the development of the regulation, Agency knowledge and experience with
the NSPS program, the previously approved ICR, and any comments
received.

	6(b)  Estimating Respondent Costs

		(i)  Estimating Labor Costs 

 

	This ICR uses a Technical Labor Rate of $57.12 per hour.  This rate is
from the United States Department of Labor, Bureau of Labor Statistics,
March 2001, “Table 10. Private industry, by occupational and industry
group.”  The rates are from column 1, “Total compensation.”  The
wage rate of $27.20 has been increased by 110 percent to account for the
benefit packages available to those employed by private industry for a
labor rate of $57.12 per hour.

	

		(ii)  Estimating Capital/Startup and Operation and Maintenance Costs

	The type of industry costs associated with the information collection
activity in the regulations is for labor and continuous emission
monitoring (CEM).  The capital/startup costs are one-time costs when a
facility becomes subject to the regulation.  The annual operation and
maintenance costs are the ongoing costs to maintain the monitor and
other costs such as photocopying and postage.

	The total capital/startup costs for this ICR are $9,000,000.  This is
the total of column D in the above table.

	The total operation and maintenance costs for this ICR are $17,775,000
.  This is the total of column G.

	The total respondent non-labor costs in block 14 have been calculated
as the addition of the capital/startup costs, and the annual operation
and maintenance costs.  The average annual cost for capital/startup and
operation and maintenance costs to industry over the next three years of
the ICR is estimated to be $26,775,000.

	6(c)  Estimating Agency Burden and Cost

	The only costs to the Agency are those costs associated with analysis
of the reported information.  Publication and distribution of the
information are part of the AFS program.  Examination of records to be
maintained by the respondents will occur as part of the periodic
inspection of sources, which is part of EPA's overall compliance and
enforcement program.

	The average annual Agency cost during the three years of the ICR is
estimated to be $22,691,832 [see Table 2].  This cost is based on the
average hourly labor rate at a GS-12, Step 1, times a 1.6 benefits
multiplication factor to account for government overhead expenses for a
total of $38.30 ($23.94 x 1.6).  These rates are from the Office of
Personnel Management (OPM) “2002 General Schedule” which excludes
locality rates of pay.  Details upon which this estimate is based appear
in Table 2 Annual EPA Resource Requirement for
Industrial-Commercial-Institutional Steam Generating Units/ NSPS subpart
Db, below.

	6(d)  Estimating the Respondent Universe and Total Burden and Costs

	Approximately 1,185 sources are currently subject to the regulation,
and it is estimated that an additional 45 sources per year will become
subject to the regulation in the next three years.

Per Year table.  This represents the number of existing sources and the
number of new sources averaged over the three-year period (i.e., the
number of new respondents over the three-year period divided by three
years).

	The number of Total Annual Responses is 2,952.

	The total annual labor costs are $32,609,435.  Details upon which this
estimate is based appear in Table 1: Annual Respondent Burden and Cost -
NSPS subpart Db, Standards of Performance for
Industrial-Commercial-Institutional Steam Generating Units.

	The total annual capital and O&M costs to the regulated entities are
$26,775,000.

	6(e)  Bottom Line Burden Hours Burden Hours and Cost Tables

	The bottom line burden hours and cost tables for both the Agency and
the respondents are attached below.  The annual public reporting and
recordkeeping burden for this collection of information is estimated to
average 200 hours per response.

	

	6(f)  Reasons for Change in Burden

	There is a decrease in burden for the Agency from the most recently
approved ICR due to a mathematical error.

				

	6(g)  Burden Statement

	The annual public reporting and recordkeeping burden for this
collection of information is estimated to average 200 hours per
response.  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.

Footnotes:

a) Assume an hourly wage of $57.12.  This amount was multiplied by the
hours per year in column E.

b) EPA estimates that there will be 25 new gas-fired steam generating
units per year (which require NOx controls), 13 new coal-fired
generating units per year (which require SO2, NOx, and PM controls), and
6 new biomass/wood (which require NOx and PM controls).

c) One-time only costs associated with the anticipated 45 new sources
per year over the next three years.

d) Assume 20 percent of initial performance tests and CEMS
demonstrations are repeated due to failures.

e) Appendix F costs are based on contractor costs of $50.00 per hour.

f) Assume that 25 percent of units have in situ CEMS and 75 percent have
extractive CEMS.

g) Respondents per year amounts (column D) in the RECORDKEEPING
REQUIREMENTS section are based on the average number of plants in
existence over the next three years.

h) The number of controls for SO2, PM and NOx for existing sources is
based on the number of existing sources from the last ICR and the ratios
established by computer modeling in the first ICR issued after subpart
Db was revised.  The average number of new sources for each control
(X*3/2) for SO2, Pm and NOx have been added to the number of existing
sources to obtain the figures for “Total number of respondents.”

i) Assume the 20 percent of units are found to be in excess of emission
standard, 80 percent are found to be in no excess.

j) Assume that 20 percent of respondents will choose to report
quarterly.

Footnotes:

a) A x B = C

b) C x D = E

c) Burden cost is calculated at a rate of $38.30 ($23.94 x 1.6 to
account for government benefits and overhead expenses).

d) All new plants subject to the standard must conduct initial
performance tests as required by sections 60.42b, 60.43b, 60.44b.

e) Assume 20 percent of initial performance tests must be repeated due
to failure.

f) All new plants subject to the standard must provide reports of these
events as required by section 60.7.

g) EPA estimates that there will be 25 new gas-fired steam generating
units per year (which require NOx controls), 13 new coal-fired
generating units per year (which require SO2, NOx, and PM controls), and
6 new biomass/wood (which require NOx and PM controls).

h) Owners of plants rated at 250 MMBTU/hr and utilizing an annual
capacity factor who seek to predict and monitor NOx emission rates
submit this plan.  It is estimated that 84 percent of NOx producing
facilities meet this criteria (84 percent of the 444 sources with NOx
controls over the next three years).

I) Semiannual reports are required of most facilities subject to the
regulation.  Assume approximately 20 percent of plants report
electronically.  The number of plants per year in these catagories were
established during promulgation of the regulation and adjusted
accordingly for this update.

j) Travel expenses (1 person x 15/plants/yr x 3 days/plant x $75 per
diem) + ($250 round trip/plant x 15 plants/yr)
