SUPPORTING STATEMENT FOR RadNet ICR

EPA ICR # 0877.10

OMB Control Number 2060-0015

Section I: Part A

1.  Identification of the Information Collection

1.(a)	Title of the Information Collection

RadNet (formerly, Environmental Radiation Ambient Monitoring System
[ERAMS])

1.(b)	Short Characterization

RadNet in this ICR refers to EPA’s national network of fixed stations
monitoring environmental radiation.  The objectives of RadNet (formerly,
Environmental Radiation Ambient Monitoring System [ERAMS] and renamed in
2005 to RadNet) are to provide a means of estimating ambient levels of
radioactive pollutants in our environment, to follow trends in
environmental radioactivity levels, and to detect and assess the impact
of fallout and other intrusions of radioactive materials.  Data
generated from EPA's RadNet have been and are being used to provide the
information base for making decisions necessary to ensure the protection
of public health.  The system enables EPA to determine if additional
sampling or other actions are required in particular cases of
radioactive release to the environment, and, where necessary, RadNet can
provide ancillary information on population exposure, radiation trends,
and other aspects of such releases.

The RadNet network is used to collect air, precipitation, drinking
water, and pasteurized milk samples.  The data from analysis of these
samples constitute the nation's single major source of environmental
radiation data.  The responsibility for operating RadNet is assigned to
the Director, National Air and Radiation Environmental Laboratory
(NAREL), Montgomery, Alabama. The component sampling stations are
distributed throughout the United States and cover each geographical
region, individual states, and major population centers.  The
respondents, primarily state and some local personnel, voluntarily
collect the samples and complete the information forms.  The forms
request descriptive information related to sample collections (e.g.,
sample type, sample location, length of sampling, and volume
represented).  RadNet is a continuous monitoring system.  Normal
sampling frequencies are as follows.

Air particulate samples are collected twice weekly.

Precipitation samples are collected after each measurable rainfall and
composited into monthly samples.

Pasteurized milk samples are collected once a month.

Drinking water samples are collected quarterly.

The samples are then forwarded to NAREL for radiochemical analyses.  To
ensure that the data generated at NAREL are of known quality, a quality
assurance plan (available upon request) is followed during all phases of
sample collection and analysis activities. 

All results are stored in the NAREL computer and made available online
at the EPA website.   The basic data of RadNet are available in 2 to 8
weeks upon request and when necessitated by circumstances can be
available daily. See Attachment 1 for the forms used by respondents and
NAREL personnel to document sampling in all RadNet media, air,
precipitation, milk, and drinking water.

The utility of RadNet data is evidenced by its extensive use by a number
of federal, state and commercial entities.  DOE's National Laboratories
(including Oak Ridge, Savannah River, Brookhaven, and Argonne) and many
universities across the country utilize the data generated by the
operation of the RadNet network.  RadNet data are also used by the
Nuclear Regulatory Commission (NRC) and NRC licensed nuclear power
plants and their environmental contractors to establish background data.
 These data are used by the power plant operators as a baseline to
ensure compliance with NRC release limits.  The states also use RadNet
data to supplement or compare with environmental radiation information
generated by their own programs.

Data from this program and specific monitoring stations have been used
to ascertain that radioactive materials detected in the environment in
October 1976, October 1980, and January 1981 were not due to nuclear
reactor releases, but were due to fallout.  During and following the
accident at Three Mile Island, Unit II(TMI-II), RadNet stations in the
adjacent states demonstrated to the public that there were no
radioactive materials in their areas as a result of the accident. 
Increased monitoring following the nuclear incident at Chernobyl in 1986
provided daily reports of atmospheric concentrations of radionuclides
across the United States.

The collection of samples will involve 302 respondents with an annual
respondent burden cost of approximately 480,073 dollars, including costs
of benefits and overhead. The respondents are not asked or required to
keep records and all supplies and equipment relating to RadNet
activities are provided by the NAREL at no cost to the respondents.

RadNet data back to 1973 are available on EPA web sites.  The data can
be accessed through the EPA web site (www.epa.gov) under laboratories or
at Envirofacts (http://oaspub.epa.gov/enviro/erams).   RadNet data on
the web are interactive--the database can be queried and searched. 
Quarterly reports are no longer produced in hard copy, due to the
availability of RadNet data online.  NAREL does not survey respondents,
other than on specific issues regarding their work as sample collectors.
  That is done through routine conversations with them via telephone as
part of the process of maintaining the flow of samples and supplies
between NAREL and respondents.

Currently, the air network of RadNet is being upgraded and expanded. 
The expansion and upgrade amounts to replacing conventional air samplers
with new air samplers that provide data in near real-time.  In addition,
the number of air samplers will increase from the current 117 samplers
to a total of 152 during the period of this ICR (from February 2010
through February 2013).  The total of 152 samplers will be comprised of
134 near-real-time samplers plus a legacy of approximately 18
conventional samplers.  The size of the other media networks (milk,
drinking water, and precipitation) are expected to remain essentially
unchanged, except for the normal fluctuation of volunteer participants. 


2.  Need for and Use of the Collection

2.(a)	Need / Authority for the Collection

The legal basis of RadNet originated and resides in Executive Order
10831 and Public Law 86-373.  Executive order 10831 was announced to the
public on July 31, 1959, and issued August 4, 1959.  This order came in
response to recommendations contained in a memorandum to the President
from Elmer B. Staats on July 31, 1959.  As reiterated before the Joint
Committee on Atomic Energy by Maurice H. Stans, these recommendations
also became a part of the legislative history of the 1959 amendments to
the Atomic Energy Act. Radioactive fallout and environmental radiation
monitoring became a responsibility of the Department of Health,
Education and Welfare (HEW) under these legal mandates.  In 1970,
Reorganization Plan No. 3 transferred HEW's fallout and radioactive
monitoring responsibilities to the Environmental Protection Agency
(EPA).  On July 1, 1973, through its Office of Radiation Programs (ORP),
EPA developed and implemented a new continuous monitoring system.  This
system, originally termed ERAMS and now called RadNet, was designed to
complete and complement the monitoring system previously instituted by
HEW's Public Health Service under Executive Order 10831.

The objectives of RadNet are to provide a means of estimating ambient
levels of radioactive pollutants in our environment, to follow trends in
environmental radioactivity levels, and to assess the impact of fallout
and other intrusions of radioactive materials.  Data generated from
EPA's RadNet have been and are being used to provide the information
base for making decisions necessary to ensure the protection of public
health.  The system enables EPA to determine if additional sampling or
other actions are required in particular cases of radioactive release to
the environment, and, where necessary, RadNet can provide ancillary
information on population exposure, radiation trends, and other aspects
of such releases.

2.(b)	Use / Users of the Data

Data generated by RadNet are used to provide a means of estimating
ambient levels of radioactive pollutants in our environment, to follow
trends in environmental radioactivity levels, and to detect and assess
the impact of fallout and other intrusions of radioactive materials. 
Data generated from EPA's RadNet have been and are being used to provide
the information base for making decisions necessary to ensure the
protection of public health.  The system enables EPA to determine if
additional sampling or other actions are required in particular cases of
radioactive release to the environment and, where necessary, RadNet can
provide ancillary information on population exposure, radiation trends,
and other aspects of such releases.

The utility of the RadNet data is evidenced by its extensive use by  a
number of federal, state and commercial entities.  DOE's national
Laboratories (including Oak Ridge, Savannah River, Brookhaven, and
Argonne) and many universities across the country utilize the data
generated by the operation of the RadNet network.  RadNet data are also
used by the Nuclear Regulatory Commission and NRC licensed nuclear power
plants and their environmental contractors to establish background data.
 These data are used by the power plant operators as a baseline to
ensure compliance with NRC release limits.  The states also use RadNet
data to supplement or compare with environmental radiation information
generated by their own programs.

Data from this program and specific monitoring stations have been used
by ORIA and others to ascertain that radioactive materials detected in
the environment in October 1976, October 1980, and October 1980 were not
due to nuclear reactor releases but were due to fallout.  During and
following the accident at Three Mile Island, Unit II(TMI-II), RadNet
stations in the adjacent states were immediately "activated" and
demonstrated to the public that there were no radioactive materials in
their areas as a result of the accident.  Increased monitoring following
the nuclear incident at Chernobyl in 1986 provided daily reports of the
atmospheric concentrations of radionuclides.  This information helped
reduce the public's fear and concern about radiation and radioactivity.

3.	Non-duplication, Consultations, and Other Collection Criteria

3. (a)	Non-duplication	

RadNet has been in operation for 37 years.  During that time, data
derived from the system have been disseminated nationally and
internationally.  The professional/information network developed over
the life of RadNet has identified other environmental radiation data 
systems in the United States, but none have RadNet's national scope or
exact collection and analytical structure.

Immediately following the accident at Chernobyl in 1986 in the former
Soviet Union, the President's order charged EPA with lead responsibility
for monitoring possible environmental effects in the United States.  It
was the unique nationwide monitoring capability of RadNet that helped
EPA respond to that Presidential Order.  Similarly, during the nine-year
EPA follow-up monitoring of the accident at Three Mile Island RadNet was
called upon because of its unique national scope and analytical
structure and capability.

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

The first Federal Register(FR) notice has been completed.  The notice
was published November 6, 2009 in FR Vol. 74, No. 214.  EPA received no
comments.

3. (c)	Consultations

NAREL is involved in continual telephone and occasionally written
communication with the respondents who supply the samples.  In addition,
NAREL is an active participant in the Council of Radiation Control
Program Directors (CRCPD), which is an association of individuals from
radiation programs from all fifty states.  These individuals and their
associates make up a significant number of RadNet data users.  NAREL's
participation in this association allows for frequent consultations on a
variety of issues involving RadNet with many RadNet data users. 
Comments from federal and state agencies and other organizations
concerning RadNet are welcomed and are noted at NAREL.  

3. (d)	Effects of Less Frequent Collection

Alternate, less frequent collection intervals have been considered but
not adopted because these would not provide the continuous current
"picture" of the radiation levels across the United States now available
with the current system.  Less frequent collection would eliminate the
ability to determine and respond to elevated radiation levels soon after
they occur and would dramatically decrease the ability to map trends in
radiation data following a release.

3. (e)	General Guidelines

The respondents must supply certain select samples (rain water and air
filters) and accompanying forms more often than on a quarterly basis. 
This is done so that elevated levels of radiation will be detected as
soon as possible so as to allow for the quickest response possible to
potential health threats.  

The respondents submit sample collection information on a one page form
that accompanies the sample to the NAREL.  Since most samples are
collected in the field, electronic means of recording or sending the
information are not feasible.  In addition, to avoid assigning incorrect
sampling information to a sample, the sample and sampling information
need to be linked when they are sent to the lab.  The most effective
means to do this is to attach a form with the information to the sample.

3. (f-g)	Confidentiality and Sensitive Questions	

The section on confidentiality and sensitive questions does not apply to
RadNet.  The respondents do not supply confidential or sensitive
information.

4.  The Respondents and the Information Requested

4.(a)	Respondents / NAICS Codes

All fifty states, primarily the State Public Health Departments (NAICS
Code 92312), send samples along with one page sample collection forms to
NAREL.  The respondents were chosen for two basic reasons: most of them
routinely collect samples of this type as part of their normal
activities, and in order to obtain meaningful information concerning
ambient radiation levels for the entire United States samples must be
collected from as many parts of the country as feasible.

 

4.(b)(i)	Information Requested

Respondents provide actual samples of air, precipitation, drinking
water, and milk.  Respondents do provide descriptive information about
their samples on one page forms (see Attachments 1-3).  The respondents
are not requested or required to maintain records.  Since the forms, as
shown in the attachments, have had only very minor changes over time
expiration dates are not included on them.  

4.(b)(ii)	Respondent Activities	

RadNet respondents must perform the following tasks in order to provide
samples to NAREL.

Read instructions concerning the sampling process

Collect samples in appropriate containers

Mail/ship samples to NAREL in Montgomery, Alabama

Complete description forms regarding samples

Perform minor calibrations on instruments

Most respondents are employees of state health agencies and routinely
perform sampling of their own that is analogous to RadNet sampling.  

5.	The Information Collected

5.(a)	Agency Activities

Since RadNet began operating in the early 1970's, the following
functions have been part of EPA's inventory of Agency activities.

Maintain a master database

Answer respondent questions

Coordinate respondent sample submissions

Maintain records of sample submissions

Publish and disseminating data from sample analyses

Analyze samples submitted by respondents

Prepare and sending sampling material

Provide maintenance and or replacements for sampling instruments

5.(b)		Collection Methodology and Management

The RadNet network involves the collection of a variety of samples
including air filters, milk, drinking water, and rain water
(precipitation) samples.  The RadNet manual (available upon request),
contains the detailed procedures used to ensure uniform collection of
the samples and the standard forms filled out by the respondents when
they collect the samples.  The forms were designed to minimize the
burden on the respondents.  In most cases only the date of sampling,
location of sampling, and the name of the individual taking the sample
are required.  Since most samples are taken in the field, an electronic
means of recording and sending this information is not feasible.  Also,
to ensure that the sample collection information accompanies the correct
sample, the sample and the information need to be sent together as a
single unit.  This is best accomplished by attaching the one page form
to each sample when it is sent to the NAREL.

Once the samples and any accompanying forms arrive at NAREL, the samples
are assigned an identification number and this number, along with the
information from the accompanying forms, is entered into the NAREL
computer.  The samples are then analyzed for a variety of radionuclides.
   Data from the analyses performed at NAREL are also entered into the
computer.  The data are stored in a database and are available to the
public online at the EPA website.  When necessitated by unique
circumstances, data from the RadNet network can be made available daily.
 The data are verified by at least two individuals at NAREL.  To ensure
that the data are accurate and reliable, all activities associated with
the RadNet network must conform to the quality assurance project plan
for RadNet, which details the data quality objectives, project
organization and responsibility, internal quality control checks, and
other areas relating to quality assurance.  

5.(c)	Small Entity Flexibility

This section is not applicable because the respondents are state
agencies.

5.(d)	Collection Schedule

The collection frequency for the samples and the accompanying sample
forms are listed below.

Sample					Collection Frequency

Milk					Quarterly	

Drinking water				Quarterly

Rain					As rain occurs

	Air filters				Two times per week

Respondents collect samples and send them to NAREL according to the
frequency listed above.  In case of an emergency, such as Three Mile
Island and Chernobyl, the frequency may be increased.	

6.	Estimating the Burden and Cost of Collection

6.(a)	Estimating Respondent Burden

Burden hour estimates are based primarily on informal telephone
conversations with respondents over the years.  Additional information
used in estimating burden hours was obtained through discussions of
NAREL personnel with personnel from state radiation departments at
Council of Radiation Control Program Directors (CRCPD) meetings.  These
conversations also revealed that the technical labor category is the
most appropriate one for all RadNet burden activities.

Although the respondent burden assumes 302 sampling stations, there can
be times when the actual number of stations reporting is less than that,
due to unexpected nonparticipation by some stations.  However,
participation is not anticipated to decrease by more than 12-15 percent
of the total of 302 participating stations.

	

6.(b)	Estimating Respondent Cost

Informal conversations and discussions with respondents have revealed
that the technical labor category is the correct one for all RadNet
respondent burden activities.  Since the hourly wages of the respondents
depend on years of employment and the pay scales of their respective
states, an actual average hourly wage would require obtaining
confidential information from the respondents.  Based on our informal
discussions at several Council of Radiation Control Program Directors
(CRCPD) meetings, the hourly rate at the GS-12(1)  level, $55.12
dollars/hour (30.21 times a 1.6 overhead multiplication factor, based
upon OPM salary tables effective January 2010 as displayed at
http://www.opm.gov/oca/06tables/html/gs_h.asp), is a good approximation
of the respondents’ hourly wage for this technical labor category. 
The respondents are not asked or required to keep records, and all
supplies and materials relating to RadNet activities are provided by the
NAREL at no cost to the respondents.

There are no capital costs for sample collectors (respondents). All
equipment and materials are supplied by NAREL. 

6.(c)	Estimating Agency Burden and Cost

Our agency burden estimates are based on our years of experience in
operating the RadNet network.  Since the activities for the operation of
RadNet involves workers at various GS levels, we used composite burden
hours and calculated hourly costs at the GS-12 level (step 1) times 1.6
(the overhead multiplication factor) to be 48.34 dollars/hour.  The
total number of annual hours devoted to RadNet by Agency personnel is
estimated to be 21,931 (1,447,220 dollars in labor costs).  In addition,
we estimate that the annual costs associated with supplying respondents
with supplies, materials and replacement parts as well as supplies
needed by NAREL to be approximately 74,000 dollars.  The total capital
costs (including supplies) are 1,383,086 dollars.  The total cost to the
Agency is 2,830,306 dollars, which includes both labor and capital
costs.  This amounts to a net decrease of 470,365 dollars annually.  An
increase in costs was attributable, primarily, to the capital
acquisitions (new samplers) and the added cost burden of the electronic
(IT) infrastructure and the increased sample load inherent in the
ongoing expansion and upgrade of RadNet’s air monitoring system. 
Because the scheduled acquisitions will be complete in 2012, the
Agency’s overall annual capital cost burden will decrease.

6.(d)	Bottom Line Burden Hours and Cost/Burden Tables

See burden tables on pages 11-13.

6.(e)	Reasons For Change in Burden

For the previous review of the ICR for RadNet, the respondent burden
hours were estimated to be 9,333 hours annually.  Based on the number of
current and new respondents resulting from the expansion of the RadNet
air monitoring network, the respondent burden hours for this ICR are
estimated to be 8,710 hours annually, which amounts to an annual net
decrease of 623 hours required of respondents.  This decrease resulted
from the installation new air monitors, which require less time from the
station operators.  The new equipment was installed as a result of
EPA’s decision to upgrade existing air monitoring equipment. 
Expansion of the network will continue annually throughout the duration
of this ICR and up through 2012.  In this ICR, the number of air
monitoring stations indicated for each year is 152.  The number 152 was
derived by averaging the total number of air monitors (real-time and
conventional) anticipated to be in place and operational for each of the
three years covered by this ICR. 

6.(f)	Burden Statement

The annual public reporting and recordkeeping burden for this collection
of information is estimated to average 0.5 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.  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 are listed in 40 CFR Part
9 and 48 CFR Chapter 15.  

To comment on the Agency's need for this information, the accuracy of
the provided burden estimates, and any suggested methods for minimizing
respondent burden, including the use of automated collection techniques,
EPA has established a public docket for this ICR under Docket ID No.

correspondence.

Section II: Part B

In the case of the RadNet network, respondents send in actual samples
such as air filters, milk, drinking water, and rain.  With each sample
the respondents send in a one page form which basically requires the
date and location of sampling, the size of the sample, and the name of
the individual taking the sample.  This is basic information that
identifies the sample and requires no real data gathering on the part of
the respondent.  The respondent simply supplies information on the
sampling process that he/she just performed.

The design of RadNet makes it the most comprehensive radiation
monitoring network in the nation.  The 300 sampling sites span the
United States and cover major population centers in all geographical
regions.  They are typically located at or near state health facilities
and samples are collected voluntarily by state personnel.  Although the
choice of sampling station locations is not based on a truly randomized
design, the nationwide dispersion of sites does represent a close
approximation to randomly selected locations with consideration given to
population centers and potential radiation source distribution.  This
arrangement maximizes the coordination with state and local agencies
collecting the samples as it does not place stations in extremely remote
and relatively inaccessible locations.

The RadNet network satisfies the three major objectives of an
environmental monitoring program as set forth by the Health Physics
Society's Committee on Upgrading the Quality of the Environmental Data
(EPA 520/1-80-012).  These objectives are:

a.	to assess dose,

b.	to determine any trends of environmental radiation dose rates and
concentrations 	

	of radioactive materials, and 

c.	to reassure members of the public and governmental organizations
regarding

 	radiation hazards and environmental radiation exposures.

The Society specifically references EPA's RadNet as an example of a
functioning environmental monitoring program that incorporates these
major desirable features.
