Protective Action Guides (PAGs), as provided in the EPA “Manua of Protective Action
Guides and Protective Actions for Nuclear Incidents” -This manual and the PAG criteria for
responding to nuclear incidents (involving releases or potential releases of specified
quantities of radioactive material) are being revised by an interagency team that is
specifically responsible for federal emergency response planning and is separate from
ISCORS. Issuance of this document is still pending. The subcommittee efforts are
focused on whether or not to recommend to the full ISCORS that the final document be
adopted as Federal Guidance for general application by all ISCORS agencies.

Federal Guidance on Radiation Exposures to Individual Members of the General Public
-Specifically, the subcommittee focus is the establishment and implementation of a
process for moving forward to develop and update Federal Guidance (i.e., a consensus
document from the Federal government) for application to members of the general public.
In CY 2000, the subcommittee identified and discussed key issues and agreed on a
potential path forward to address fundamental principles. Additionally, the subcommittee
began drafting an outline that was subsequently developed into a draft guidance
document. Finally, the Chair of the subcommittee wrote a letter explaining this guidance
effort to the Health Physics Society, which was subsequently published in the Health
Physics Society's Newsletter in January 2001.

The approach that is being considered by the subcommittee focuses on “optimization.”

In other words, the practice of making decisions based on the practical considerations of
ALARA principles. The existing limit, issued in 1960, is a 500-millirem (i.e., 5-millisievert)
dose per year to a member of the general public. Compared to the knowledge existing
when this limit was first proposed, current efforts can substantially lower exposures by
recognizing and using the strides made in both the science of radiation dose analysis and
the understanding of associated risks.

Risk-Dose Methodology —-DOE asked the subcommittee to recommend a simplified
method for estimating excess cancer risk when only the total dose is known (i.¢., when
radionuclide-specific information is not available). EPA staff prepared a draft approach
that can be used to make qualitative comparisons of risk. This approach uses a
conservative dose conversion factor that is based on the risk from uniform external
irradiation of an average member of the population by gamma radiation. Although this
approach is not acceptable for determining compliance with risk-based standards, it can
be used for the kinds of qualitative comparisons that DOE is interested in. A final version
of the method, with appropriate caveats, is awaiting review by the subcommittee before
general distribution.

Ecological Risk —Although the subcommittee did not have a CY 2000 goal related to
ecological risk (i.e., risk to plants and animals from radiation exposure), the subcommittee
kept abreast of DOE progress in this area by receiving presentations during the year.

The Interagency Steering Committee on Radiation Standards (ISCORS) prepared this annual report for
ISCORS member agencies as a means of documenting the ISCORS calender year 2000 activities and
accomplishments and plans for calender year 2001. We wish to thank the ISCORS members for their
participation and contributions to the many topics discussed over the past year regarding radiation issues
important to (1) the public, (2) federal, state, and local agencies, and (3) national and international
communities. In addition, we extend our compliments to all of the subcommittee chairpersons and their
members for significant support and accomplishments within the past year on numerous radiation issues,
and for developing useful information, examples of which are located at the new ISCORS website
(www.ISCORS.org). The subcommittees outlined an aggressive list of challenges for 2001 and the full
committee looks forward to receiving subcommittee recommendations on the specific topics each is
addressing.

The full ISCORS met in March, June, September, and December 2000. The June 2000 meeting was open
to the public for observation. At each full committee meeting, the subcommittees reported on their yearly
activities and progress. The full committee also reviewed and received focused presentations on a wide
variety of special topics, some of which included the following:

* the National Research Council's Report, “Long Term Institutional Management of U.S. DOE
Legacy Waste Sites’ Institutional Controls”;

* the General Accounting Office's (GAO) audit report, “Radiation Standards: Scientific Basis
inconclusive, and EPA and NRC Disagreement Continues”;

* the U.S. Nuclear Regulatory Commission’s (NRC) decommissioning program status and
its report, NUREG-1727, “NMSS Decommissioning Standard Review Plan”;

¢ low dose radiation research efforts by DOE and U.S. Department of Health and Human Services
(DHHS);

* the National Academy of Sciences’ (NAS) study on “Improving Practices for Regulating and
Managing Low-Activity Radioactive Waste”;

* the U.S. Environmental Protection Agency's Superfund program guidance for using NRC's
regulations for uranium mill tailings cleanup.

Over the past few years, the full ISCORS committee has established a strong intragovernmental working
relationship that benefits each member agency and significantly aids in identifying topics of interest to each
agency. For both member representatives and the public, the ISCORS process and access to information
are made visible by the annual report. We appreciate comments on this annual report and expect that it
will be used as a reference for overview of committee activities. You may send comments on the report to
Mr. James Kennedy or Ms. Susanne Woods (U.S. NRC, Mail Stop T-7J8 Washington, DC 20555), or Mr.

Inactive Status -As proposed by the chair of the subcommittee, ISCORS agreed that the
subcommittee be placed in an inactive status until it can be assigned a specific task.
Additionally, ISCORS asked the subcommittee to continue to monitor international and
national efforts on recycle and reuse, monitor the control of the orphan sources (i.e.,
radioactive sources with no apparent owner) program, and support the CRCPD with
federal input on recycle, reuse, and orphan sources. A conference call every quarter
among the subcommittee members was suggested as an efficient means of
accomplishing these goals.

Planned Activities in CY 2001:

1. Remain in an inactive status until a specific task is identified by ISCORS.

2. Continue to monitor international and national efforts on recycle and reuse, monitor the
control of the orphan sources (i.e., radioactive sources without an identifiable owner)
program, and support the CRCPD with federal input on recycle, reuse, and orphan
sources.

Risk Harmonization Subcommittee Highlights
Subcommittee Chair: Edward Regnier, DOE [(202) 586-5027}

The Risk Harmonization Subcommittee was initiated to review similarities and

differences between NRC and EPA risk assessment and risk management approaches.

Accomplishments in CY 2000:

1.

Presentation on Risk Harmonization - The subcommittee arranged for a presentation to
ISCORS by Dr. David Kocher entitled, “Consistent Regulation of Public Exposures to
Radionuclides and Hazardous Chemicals: Keys to Risk Harmonization.” The presentation
emphasized several points: (1) the key to risk harmonization is the consistent application
of as low as reasonably achievable exposures to all situations; (2) risk harmonization does
not mean achieving consistency in numerical standards (limits or goals); (3) substantial
differences in numerical standards for different exposure situations can be reasonable.
The information presented will be used, for example, by the Federal Guidance
Subcommittee during revision of guidance on radiation exposures to members of the
general public.

Optimization Task Group -The subcommittee formed a task group to look at optimization
(ie., the practice of making decisions based on the practical considerations of ALARA)
issues as they relate to risk harmonization. The Optimization Task Group will develop a
table that describes statutory, regulatory, and other requirements for using cost-benefit
analysis, ALARA, or related optimization considerations in setting standards.

Institutional Controls Task Group -The subcommittee also formed a task group to
continue the ongoing effort addressing the use of institutional controls. The Institutional
Control Task Group added the RCRA hazardous waste facility program to its tables of
institutional controls. Additionally, the group conducted a poster session at the Waste
Management 2000 conference on institutional controls in various federal programs and the

HISTORICAL INFORMATION

The Interagency Steering Committee on Radiation Standards (ISCORS) was formed in
response to October 27, 1994, letters from Senator John Glenn to the U. S. Nuclear
Regulatory Commission (NRC); the U.S. Environmental Protection Agency (EPA); and
the Office of Science and Technology Policy (OSTP). In his letter, Senator Glenn charged
EPA and NAC, in coordination with the Committee on Interagency Radiation Research and
Policy Coordination (CIRRPC), to develop a plan for a “path forward” to address the
inconsistencies, gaps, and overlaps in current radiation protection standards. ISCORS is
one of the committees OSTP recommended for achieving the goals of the now defunct
CIRRPC. The objectives of the ISCORS include the following: (1) facilitating a consensus
on acceptable levels of radiation risk to the public and workers; (2) promoting consistent
risk-assessment and risk-management approaches in setting and implementing standards
for occupational and public protection from ionizing radiation; (3) promoting completeness
and coherence of federal standards for radiation protection; and (4) identifying interagency
issues and coordinating their resolution.

Since its inception, NRC and EPA have co-chaired the ISCORS. The current co-chairs are
John T. Greeves, NRC, and Frank Marcinowski, EPA. In addition to NRC and EPA,
ISCORS membership also includes senior managers from other federal agencies: U.S.
Department of Defense (DOD); U.S. Department of Energy (DOE); U.S. Department of
Labor Occupational Safety and Health Administration (OSHA); U.S. Department of
Transportation (DOT); and U.S. Department of Health and Human Services (DHHS).
Representatives of the Office of Management and Budget (OMB), OSTP, and various states
are observers at meetings. Committee meetings involve pre-decisional intragovermmental
discussions and, as such, are not normally open for observation by members of the public or
media. However, summary meeting notes are available in the NRC Public Document Room
and at the ISCORS website (www.ISCORS.org). The Committee does not act as a
decision-making body. Instead, it provides recommendations and summaries of its activities
on specific issues to both the heads of member agencies, and to OMB and OSTP, via an
annual report. The Committee meets approximately once each calendar quarter. The first
meeting was held on April 5, 1995.

The full ISCORS committee has established subcommittees, as needed, to conduct its
technical work (e.g., to address specific issues of concem or significant interest). ISCORS
has formed the following subcommittees: Clean-up; Mixed Waste; Recycle; Risk
Harmonization; Sewage Sludge; Naturally Occurring Radioactive Materials (NORM); and
Federal Guidance. The subcommittee activity section of this report summarizes the
activities of each subcommittee. No new subcommittees were formed in 2000.

EPA initiatives were included: (1) EPA storage and disposal of commercial low-level mixed
waste rulemaking; and (2) EPA Low-Activity (i.e., low radioactivity ) Mixed Waste Initiative.
In addition to briefings on the plans and status of the initiatives, the members provided
insights and technical suggestions to the EPA and shared related technical information.

OE Radiological C | Criteria (Ri -The subcommittee kept informed of the DOE
approach for disposal of mixed waste in RCRA subtitle C (hazardous waste) facilities.
This approach is similar to the EPA's second approach described above. The RCC
approach is a framework for the disposal of certain DOE mixed wastes with low
radioactivity concentrations. This treated waste would then be disposed of ina RCRA
C-type disposal cell, rather than a mixed waste disposal cell. Consequently,
implementation of this approach will eliminate dual regulation of the waste.

Planned Activities in CY 2001:
1.

Continue to provide advice as needed on implementation or guidance for the EPA mixed
waste rule published in May 2001.

Hold discussions and exchanges on current mixed waste initiatives and issues.
Specifically, the subcommittee efforts will continue to focus on the coordination and
sharing of technical information for use by member agencies and observers who
address mixed waste issues.

Provide input toward resolving issues for the DOE Radiological Control Criteria (RCC)
initiative that is focused on disposal of certain DOE mixed waste and complete any final
review or analysis as needed.

Provide input to and help answer questions from the Conference of Radiation Control
Program Directors (CRCPD) (i.e., directors of individual state or local radiation
regulatory programs) reviews and workshops on the DOE RCC concept.

Recycle Subcommittee Highlights
Subcommittee Chair: Robert A. Meck, NRC [(301) 415-6205]

The Recycle Subcommittee reviews issues on radiological control of materials.

Accomplishments in CY 2000:

1.

Federal Agency Activities and International Dev -The subcommittee kept
abreast of federal agency activities and international developments. At NRC, development
of technical information such as radiation dose assessments, inventory, and some cost
estimates is continuing to address material and equipment that have very low levels of
associated radioactivity and are candidates for clearance. The DOE suspended release of
metals with radioactivity on the surface, and placed a moratorium on the release of metals
with volumetric radioactivity (i.e., radioactivity that is distributed throughout the metal).
EPA tabled rulemaking activities on clearance and will re-focus its efforts on the
interception of imported goods that should be placed under radiological control. The
international Atomic Energy Agency is continuing efforts to derive and publish clearance
levels based on 10 :Sv/a (1 mrem/y).



meeting date, distributing a draft agenda for the meeting, arranging for a
meeting facility, and documenting and distributing summary meeting notes.

2. Summary meeting notes will be provided by the host agency to designated
representatives of each of the member agencies, OMB, OSTP, and, as
appropriate, Congressional contacts and other groups. The host agency will
distribute draft notes within one week of the committee meeting and final
meeting notes at least two weeks before the next committee meeting. NRC will
also place a copy of the summary meeting notes in the Public Document Room.

3. The committee will establish a plan for approximately a six-month period.
Specific agendas will be developed for each meeting based on the general
plan.

4. The committee will meet approximately once each calendar quarter, with
more frequent meetings, as needed to address specific issues.

Subcommittees

1. The committee may create subcommittees to focus on specific issues or
activities (e.g., recycling criteria, risk harmonization, cleanup standards).
Subcommittees will follow the same understandings and procedures as the full
committee.

2. Subcommittees will meet at a frequency and location as determined
necessary by the subcommittee.

4.  Revised-Draft Guidance on Radioactive Materials in Sewage Sludge and Ash at Publicly
Owned Treatment Works -The June 2000 draft document was issued for public comment.
The document was developed using topical areas provided as input from various publicly
owned treatment works. The subcommittee will continue to accept comments until it
issues the final document.

Planned Activities in CY 2001:

1. Incorporate, as appropriate, the EPA Science Advisory Board RAC report on the
subcommittee draft dose modeling report, "Radionuclides in Sewage Sludge Dose
Assessment” (November 5, 2000). Complete and issue the revised dose modeling
report.

2. Complete the database compilation of sample analysis results, after review by the
subcommittee. Summarize the data using the categories identified in the survey
questionnaire (during the first phase of the survey), such as geographic location, type of
sewage treatment, size of facility and flow rate. Issue a completed sewage survey data
report and results summary.

3. Finalize and issue the POTW guidance document.

NORM Subcommittee Highlights
Subcommittee Chair: Loren Setlow, EPA [(202) 564-9445]

The NORM Subcommittee mission is to ensure effective communication and
coordination among member agencies involved with regulatory, oversight, and
disposal issues for NORM wastes, and products containing NORM.

Accomplishments in CY 2000:

1. NORM Forum Activities -The subcommittee provided a forum for exchanging information
on-current agency activities, proposed regulations, new reports, as well as on planned
international meetings at which NORM issues were to be discussed.

2. — Briefings on Major Informational Areas -Member agencies were briefed on (1) the CRCPD
Part N Implementation Plan, (2) NRC decisions on source materials containing less than
<0.05 percent uranium and thorium, and (3) NRC decisions for uranium/thorium mineral
extraction and processing operations.

3. National Academy of Sciences Recommendations on TENORM -Member agencies were
provided information on and copies of the EPA Report to Congress that responds to the
National Academy of Sciences recommendations on TENORM (Technologically Enhanced
Naturally Occurring Radioactive Materials). [TENORM is a term applied to radioactive
material that is produced when human activity, such as uranium mining or water
treatment, concentrates or increases human or environmental exposure to radionuclides
that occur naturally in mineral ores, solids, water, or other natural materials.}

4. DOT Regulations -The subcommittee discussed the DOT request for comments to update
transport regulations in consideration of revised international radiation standards.



different roles they play in managing risk. Institutional controls may include land
ownership, maintenance and monitoring, and well-documented information about the
location of a site with residual radioactivity that is preserved for use by future generations.

Planned Activities in CY 2001:

1. Continue work on tables that explain the optimization requirements in each agency.

2. Provide a narrative to accompany the tables on institutional controls, and investigate if
the CERCLA program can be an added resource.

Sewage Sludge Subcommittee Highlights

Subcommittee Co-chairs: Bob Bastian, EPA [(202) 260-7378]
Rosemary Hogan, NRC [(301) 415-7484]

The Sewage Sludge Subcommittee is conducting an NRC/EPA joint survey to collect
information concerning radioactive materials in sewage sludge and ash from sewage

treatment plants [referred to in industry as publicly owned treatment works (POTWs)].

This is a two part survey effort: (1) a survey questionnaire; and (2) a program to sample

and analyze sewage sludge and incinerator ash. The result will be guidance
documents and assistance with potential rulemaking decisions.

Accomplishments in CY 2000:

1.

Draft Sewage Sludge Dose Modeling Report -As part of the subcommittee efforts to
revise its draft sewage sludge dose modeling report, "Radionuclides in Sewage Sludge
Dose Assessment” (November 5, 2000), the Radiation Advisory Committee (RAC) of the
EPA Science Advisory Board reviewed the document in December 2000. In general, the
review results were positive and supportive of the subcommittee efforts to (1) revise the
draft document, (2) use RESRAD computer modeling as the basis, and (3) conduct
sensitivity and uncertainty analyses using Monte Carlo methods (a type of probability
analysis that analyzes various scenarios) with consideration of relevant correlations.
The need for documenting all procedures and assumptions was emphasized.

The final RAC report addressing the draft document is expected to be made available by
midyear 2001. The subcommittee plans to use the NRC Advisory Committee on Nuclear
Waste for the review of the final dose modeling document.

Sampling Phase of the Sewage Sludge Survey -The sample collection phase of the
sludge survey was completed. Sewage sludge and ash samples from more than 300
POTWs were received as a part of the survey. The results of the sample analyses are
being compiled in a database, after being reviewed by the subcommittee.

ing with the Association of Metropolitan if ies -This meeting was
arranged for the subcommittee to learn more about the National Biosolids Partnership
independent modeling activities for comparison to and use during the ISCORS efforts.

Clean-up Subcommittee Highlights
Subcommittee Chair: Cheryl Trottier, NRC [(301) 415-6232]

The Clean-up Subcommittee is evaluating radionuclide concentrations for screening
decommissioning sites and is a forum for exchanging information and promoting
partnerships addressing radiation clean-up standards and guidance.

Accomplishments in Calender Year 2000 (CY 2000):

1. Draft Guidance on Computer Models for Site Clean-up and Related Decisions
The subcommittee developed a draft document intended to provide a resource to
radioactive material users who need information on how to select radiation dose and risk
assessment computer models for use in site cleanup activities and decision making. The
document is available on the ISCORS website for review.

The guidance document will be in the form of an “on-line catalog” via the Internet. The
guidance will combine information developed by ISCORS member agencies regarding
model selection criteria and address the capabilities of specific models.

Planned Activities in CY 2001:

1. Finalize a aocument intended to provide a resource iv radivaclive malerial users who
need information on how to select radiation dose and risk assessment computer models
for use in site cleanup activities and decision-making.

2. Format the guidance document on computer modeling as an “on-line catalog” that is
accessible via the Internet.

3. Pilot the “on-line catalog” format, then include additional radiation dose and risk
assessment models and a description of their capabilities.

Mixed Waste Subcommittee Highlights
Subcommittee Chair: Gus Vazquez, DOE {(202) 586-7629]

The Mixed Waste Subcommittee is a forum for exchanging information on mixed waste.

Accomplishments in CY 2000:

1. EPA Initiatives -Among the various agency mixed waste (i.e., waste comprised of both
radioactive and RCRA hazardous material components) initiatives shared by the
subcommittee members and briefed to the full ISCORS at its quarterly meetings, two

Planned Activities in CY 2001:

1.

Complete review of the Oak Ridge National Laboratory prepared report for EPA entitled,
“Dosimetric Significance of the ICRP’s Updated Recommendations, 1989-Present, and
Implications for Federal Guidance,” and related analyses of economic and regulatory
implications to provide recommendations to the full ISCORS regarding the adoption of
ICRP 60/66/68.

Upon submittal of the revised Protective Action Guides (PAGs), as provided in the EPA
“Manual of Protective Action Guides and Protective Actions for Nuclear incidents,”
review the PAG criteria and make a recommendation to the full ISCORS on whether to
issue the product as federal guidance.

Complete the draft federal guidance on radiation exposures to individual members of the
general public and revise the document based on review comments from the full
ISCORS.

Complete review of the risk-dose methodology that was developed in CY 2000 for
estimating excess cancer risk and making qualitative risk comparisons in situations
where radionuclide-specific information is not available and only the total radiation dose
is known.

Continue as a forum for discussing issues related to ecological risk and reviewing
material addressing this subject during the coming year.

sites Geographic Information System.

ISCORS Federal Guidance Subcommittee Guidance -The subcommittee held discussions
on the Federal Guidance Subcommittee efforts to develop new draft guidance addressing
exposures to members of the public.

Pianned Activities in CY 2001:
1.

Provide input to ongoing projects of the ISCORS Sewage Sludge Subcommittee, and
the Federal Guidance Subcommittee.

Review and comment on the EPA draft Technical Report on Uranium Mining TENORM.

Complete a paper on NORM/TENOR\M that identifies different agency responsibilities for
these materials.

Consider a recommendation to OSHA to update its standard to adopt 10 CFR Part 20
(NRC).

Federal Guidance Subcommittee Highlights
Subcommittee Chair: Julie Rosenberg, EPA [(202) 564-9154]

This subcommittee works with EPA to produce Federal Guidance, including Presidential

Guidance and technical reports, that supports the development of consistent national
radiation protection standards and implementing guidance. The subcommittee serves

as the forum for coordination among federal and state government agencies interested
in any or all aspects of Federal Guidance. The forum ensures that all agencies have

opportunities for input before and during development of the Federal Guidance.

Accomplishments in CY 2000:

1.

White Paper on New Dosimetric Methods -Technical analysis was completed by the
subcommittee. This paper will address whether Federal agencies should adopt the newer
International Commission on Radiation Protection (ICRP) recommendations for dosimetric
systems contained in ICRP 60/66/68. Currently, earlier ICRP reports (26/30) are used.
During the last year, Oak Ridge National Laboratory prepared a report for EPA entitled,
“Dosimetric Significance of the ICRP’s Updated Recommendations, 1989-Present, and
Implications for Federal Guidance.” The report highlights the effects caused by these
differences, particularly changes in the dose and risk coefficients. A group of Federal
Guidance Subcommittee members began reviewing the report for discussion with the full
subcommittee on (1) decisions about what, if anything, should be done toward adopting
the newer ICRP recommendations and (2) both the related technical changes and
regulatory implications.
