i licensed nuclear facility, there are no current specific criteria in Part 20 goveming releases of -
                      -- solid materials by licensees, although there are some regulations that cover the release of
                      ;certain materials. Therefore, if a licensee requests approval of release of solid material, the NRC must consider the request on a case-by-case basis using existing regulatory guidr.nce, license -
          ,              conditions, NRC Branch Technical Positions, etc.
The Commission recently amended its regulations in Part 20 (Subpart E) to establish criteria for unrestricted use of facility structures and lands'at a decommissioned site (Federal Register, July 21,1997). Subpart E of Part 20 is focused on protection of persons entering and using decommissioned structures and lands at a site after a nuclear facility terminates its NRC g                        license, but does not btherwisje address release of solid material.                                    #

These surface contamination levels are stated in terms of measurable radioactivity levels (observed disintegrations por minute per 100 square centimeters of surface area), the values of which were based principally' on the capabilities of readily available instrumentation at the time
            - the guide was developed. Regulatory Guide 1.86 does not contain dose cliteria. For some situations, the NRC will incorporate the values in the table in Regulatory guide 1.86 into the license conditions of a facility.

Intemational Efforts.1There is considerable ~ effort by other nations and by intemational

                  ; standards could create confusion and economic disparities in commerce.                                  l 1
l The IAEA is an agency of the United Nations made up of member states from a number -
                  - of countries which develops, by consensus,'various broad radiation standards for matters where
                  - there are intomationalimplications. The NRC,M_nggal                                pen        ,and
                  . the]DepTirtirl@GiffdlWD990E generally provide input and review n dd$relSpment of IAEA standards.
The generally accepted term in the intemational community for release of materials for unrestricted use is " clearance." The'IAEA is currently in the process of revising its report on
                                                        ~
clearance levels for publication as Safety Series guidance for its member states (IAEA-TECDOC-855, Clearance Levels for Radionuclides in Solid Materials). This report was i
published in draft in January 1996 for a three-year trial use by the IAEA's member countries.
2 This report contains levels of radionuclides in solid materials that may be released for unrestricted use, or." cleared." The basis for the proposed clearance levels is a level of constraint of 1 millirem per year (mrom/yr) of exposure of members of the public from 'likely'
                  ' exposure scenarios and 10 mrem /yr from 'untiliety' scenarios.

U.S. Environmental Protection Aoency (EPA). The EPA, although not a regulator of
    ' licensees, is responsible for setting generally applicable environmental standards for radioactive materials under the Atomic Energy Act. The NRC, in regulating its licensees, implements environmental standards that EPA promulgates in the area of radiation protection. In the absence of EPA standards in a particular area, for example in the area of release of solid materials, the NRC has the authority to set radiation protection standards for its licensees. This can cause potential problems with the finality of NRC licensing decisions if EPA later issues standards in a particular area that are different from regulations that NRC has previously issued.
  - Thus, it is important for the NRC to closely involve EPA in developing 'its standards.
M ia b l                    ~
in addition, as noted lateri      ctionh the EPA has completed studies on environmentalimpacts of clearance of materials. The NRC and EPA have, and plan to continue to have, coordinated efforts in this area to ensure that effective and consistent release standards        -
are established, while minimizing duplication of effort. Accordingly, the EPA will not only be an jfM 5 important participant in the NRC rulemaking workshops, but the NRC also plans to consult extensively with EPA throughout.the rulemaking process.
In setting generally applicable environmental standards, EPA sets standards for a wide 4crue_
  - range of materials, including Aces which contain naturally occurring radioactive materials that have been enhanced as a result of man-made processes. For example, the ash from buming of S-N- 91

and guidance in four principal areas, one of which was setting a standard for release of solid materials for recycle. The Commission decided that a more extensive public involvement process in establishing these areas would be beneficial and hence instituted a moratorium on the BRC Policy in July 1991. Subsequently, in October 1992, the U.S. Congress enacted the Energy Policy Act of 1992 which revoked the BRC Policy Statement.
The NRC's current efforts differ from those associated with the BRC Policy in several ways. Unlike the broad policy-setting approach of the BRC policy, the NRC's current effort is focused on considering establishment of specific requirements for release of solid materials, which protect public health and safety, consistent with the existing framework of requirements in            .

These could include ' evaluation of radiation dose to individuals from release of solid i
materials, assessment of collective doses to different population groups from the release,        -

Some of these impacts may be competing. For example,'a lower dose criterion would result in less material available for release (and instead sent to a LLW disposal site) which, in tum, would lower the radiation dose impact to the public from exposure to that material.' However, the lower dose criterion could cause an increase in other impacts, for
                . example g}e thomemen+edelegical impacts associated with miningggpBogort, and transport of                      ;
fres5 metal to replace that sent to a LLW disposal site. Because these impacts would take place over different time periods and expose different populations, a precise comparison is difficult.
Nevertheless, the decision-making process could consider these impacts separately and also consider the not collective impact for these disparate factors.

As a first step in' assessment of impacts, the NRC has issued a draft report for comment that provides a technical basis for determining potential doses to individuals from a wide range I
of potential scenarios by which members of the public could come in contact with material that j
had been released for unrestricted use (or " cleared") from licensees '(" Radiological Assessment
          - for Clearance of Equipment and Material from Nuclear Facilities", NUREG-1640, February                    i 1999).' The report contains an analysis of material _ flow models based on an evaluation of the          l l
recycle / reuse industry in the U.S. and of potential scenarios by which a member of the public        'j could reasonably'expe(t to be exposed. . Solid materials that are candidates for release that are        i evaluated in the report include iron /s; eel, copper, aluminum, and concrete. The EPA has                1 1
          - Issued a similar report which is accessible on EPA's website at http://www. epa. gov / radiation /cleanmetals/ publications.htm. While some of'the analysis              i i
approaches of the EPA report are different from NRC's report, the overall results from the EPA and the NRC reports are similar.
Cost-benefit considerations: Executive Order 12291 contains provisions requiring that, in their rulemakings, Federal agencies consider cost-benefit evaluations of alternative courses of .
          . action. ? Consistent with Executive Order 12291, NRC has established guidelines for preparing regulatory analyses of alternative courses of action in support ofits rulemaking decisions (NUREG/BR-0058). Benefits would generally derive from the not reduction in environmental
          ' impacts discussed above. Costs which could be' included in a regulatory analysis could include:

l , However, unlike the regulations applicable to gaseous and liquid releases from a

~

i licensed nuclear facility, there are no current specific criteria in Part 20 goveming releases of -

-- solid materials by licensees, although there are some regulations that cover the release of

certain materials. Therefore, if a licensee requests approval of release of solid material, the NRC must consider the request on a case-by-case basis using existing regulatory guidr.nce, license -

The Commission recently amended its regulations in Part 20 (Subpart E) to establish criteria for unrestricted use of facility structures and lands'at a decommissioned site (Federal Register, July 21,1997). Subpart E of Part 20 is focused on protection of persons entering and using decommissioned structures and lands at a site after a nuclear facility terminates its NRC g license, but does not btherwisje address release of solid material. #

~ Solid materials include metals, building concrete, onsite soils, equipment, fumiture, etc.,

. that are present at,'and/or used in, licensed nuclear facilities during routine operations. Most of 3 this material will have no radioactive contamination, although some materials can have radioactive contamination either on their surfaces or distributed within their volumes.

Contamination can be distributed in the volume of materials because: (1) they are relatively porous (e.g., soil) allowing contamination to spread into the material; (2) they become radioactive through activation; or (3) a recycling process (e.g., metal melting) can cause v,

1 (a) Reaulatory Guide 1.86. This guide, which was developed by the Atomic Energy Commission in 1974, provides a table of Acceptable Surface Contamination Levels for various

. radionuclides, including natural and enriched uranium, transuranics, and fission products.

These surface contamination levels are stated in terms of measurable radioactivity levels (observed disintegrations por minute per 100 square centimeters of surface area), the values of which were based principally' on the capabilities of readily available instrumentation at the time

- the guide was developed. Regulatory Guide 1.86 does not contain dose cliteria. For some situations, the NRC will incorporate the values in the table in Regulatory guide 1.86 into the license conditions of a facility.

the material is released without any radioactive contamination present on, or in, it; instead, it means that the material may be released with very low amounts of contamination that is not i i

Intemational Efforts.1There is considerable ~ effort by other nations and by intemational

agencies, such as the Intemational Atomic Energy Agency (IAEA), to set standards in this area. I

. Consistency with standards set by other nations and intemational agencies is' important because j

!' 1 L . materials can be both imported'and exported between the U.S. and other countries and differing .

standards could create confusion and economic disparities in commerce. l 1

l The IAEA is an agency of the United Nations made up of member states from a number -

- of countries which develops, by consensus,'various broad radiation standards for matters where

- there are intomationalimplications. The NRC,M_nggal pen ,and

. the]DepTirtirl@GiffdlWD990E generally provide input and review n dd$relSpment of IAEA standards.

The generally accepted term in the intemational community for release of materials for unrestricted use is " clearance." The'IAEA is currently in the process of revising its report on

~

clearance levels for publication as Safety Series guidance for its member states (IAEA-TECDOC-855, Clearance Levels for Radionuclides in Solid Materials). This report was i

published in draft in January 1996 for a three-year trial use by the IAEA's member countries.

2 This report contains levels of radionuclides in solid materials that may be released for unrestricted use, or." cleared." The basis for the proposed clearance levels is a level of constraint of 1 millirem per year (mrom/yr) of exposure of members of the public from 'likely'

' exposure scenarios and 10 mrem /yr from 'untiliety' scenarios.

U.S. Environmental Protection Aoency (EPA). The EPA, although not a regulator of

' licensees, is responsible for setting generally applicable environmental standards for radioactive materials under the Atomic Energy Act. The NRC, in regulating its licensees, implements environmental standards that EPA promulgates in the area of radiation protection. In the absence of EPA standards in a particular area, for example in the area of release of solid materials, the NRC has the authority to set radiation protection standards for its licensees. This can cause potential problems with the finality of NRC licensing decisions if EPA later issues standards in a particular area that are different from regulations that NRC has previously issued.

- Thus, it is important for the NRC to closely involve EPA in developing 'its standards.

M ia b l ~

in addition, as noted lateri ctionh the EPA has completed studies on environmentalimpacts of clearance of materials. The NRC and EPA have, and plan to continue to have, coordinated efforts in this area to ensure that effective and consistent release standards -

are established, while minimizing duplication of effort. Accordingly, the EPA will not only be an jfM 5 important participant in the NRC rulemaking workshops, but the NRC also plans to consult extensively with EPA throughout.the rulemaking process.

In setting generally applicable environmental standards, EPA sets standards for a wide 4crue_

- range of materials, including Aces which contain naturally occurring radioactive materials that have been enhanced as a result of man-made processes. For example, the ash from buming of S-N- 91

licensing decisions to exempt from regulatory control certain practices involving small quantities I of radioactive material. The BRC Policy was envisioned to have applicability in NRC rulemaking  !

and guidance in four principal areas, one of which was setting a standard for release of solid materials for recycle. The Commission decided that a more extensive public involvement process in establishing these areas would be beneficial and hence instituted a moratorium on the BRC Policy in July 1991. Subsequently, in October 1992, the U.S. Congress enacted the Energy Policy Act of 1992 which revoked the BRC Policy Statement.

The NRC's current efforts differ from those associated with the BRC Policy in several ways. Unlike the broad policy-setting approach of the BRC policy, the NRC's current effort is focused on considering establishment of specific requirements for release of solid materials, which protect public health and safety, consistent with the existing framework of requirements in .

' Alternatives:

l The NRC has the following two broad options related to the issue of inconsistency of its 1 regulations on release standards and licensee requests for release of solid materials:(1) continue the current practice of handling of licensee requests for release of solid materials on a case-by-case basis, or (2) include requirements in Part 20, as part of a consistent regulatory framework for evaluating releases of all materials, that would allow it to make decisions on licensee requests for release of solid materials that are protective of public health and safety:

.4 Hupian health and environmental impacts: In assessing potential rulemaking altamatives, NRC would ' consider a broad range of possible impacts, both radiological and non-radiological. These could include ' evaluation of radiation dose to individuals from release of solid i

materials, assessment of collective doses to different population groups from the release, -

ku l b 487 I a M8*l transportation, processing and disposalimpacts, land impacts use impacts,on andbida,ti m ra i A-socetalimpacts. Some of these impacts may be competing. For example,'a lower dose criterion would result in less material available for release (and instead sent to a LLW disposal site) which, in tum, would lower the radiation dose impact to the public from exposure to that material.' However, the lower dose criterion could cause an increase in other impacts, for

. example g}e thomemen+edelegical impacts associated with miningggpBogort, and transport of  ;

fres5 metal to replace that sent to a LLW disposal site. Because these impacts would take place over different time periods and expose different populations, a precise comparison is difficult.

Nevertheless, the decision-making process could consider these impacts separately and also consider the not collective impact for these disparate factors.

f' T

5 -/ 4 -79

r l

4 i

As a first step in' assessment of impacts, the NRC has issued a draft report for comment that provides a technical basis for determining potential doses to individuals from a wide range I

of potential scenarios by which members of the public could come in contact with material that j

had been released for unrestricted use (or " cleared") from licensees '(" Radiological Assessment

- for Clearance of Equipment and Material from Nuclear Facilities", NUREG-1640, February i 1999).' The report contains an analysis of material _ flow models based on an evaluation of the l l

recycle / reuse industry in the U.S. and of potential scenarios by which a member of the public 'j could reasonably'expe(t to be exposed. . Solid materials that are candidates for release that are i evaluated in the report include iron /s; eel, copper, aluminum, and concrete. The EPA has 1 1

- Issued a similar report which is accessible on EPA's website at http://www. epa. gov / radiation /cleanmetals/ publications.htm. While some of'the analysis i i

approaches of the EPA report are different from NRC's report, the overall results from the EPA and the NRC reports are similar.

Cost-benefit considerations: Executive Order 12291 contains provisions requiring that, in their rulemakings, Federal agencies consider cost-benefit evaluations of alternative courses of .

. action. ? Consistent with Executive Order 12291, NRC has established guidelines for preparing regulatory analyses of alternative courses of action in support ofits rulemaking decisions (NUREG/BR-0058). Benefits would generally derive from the not reduction in environmental

' impacts discussed above. Costs which could be' included in a regulatory analysis could include:

(1) the costs of altamative courses of action, iricluding surveys atihe nuclear facilit@gBW!Ist n : $ ; w n: e- . :, & .m 03Jw %. 6;nwoex to verify that permissible release levels have been met; (2) the potential for having to respond tom positive alarms atm facilities (3) economic impact on ,
