NUCLEAR REGULATORY COMMISSION
Memorandum of Understanding Between the U.S. Environmental
Protection Agency and the U.S. Nuclear Regulatory Commission;
Consultation and Finality on Decommissioning and Decontamination of
Contaminated Sites
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice of issuance.
-----------------------------------------------------------------------
SUMMARY: The Nuclear Regulatory Commission signed a Memorandum of
Understanding (MOU) with the Environmental Protection Agency on the
radiological decommissioning and decontamination of NRC-licensed sites.
The MOU signed by NRC and EPA provides that EPA will defer exercise of
authority under the Comprehensive Environmental Response, Compensation
and Liability Act (Superfund) for the majority of facilities
decommissioned under NRC authority. The MOU includes provisions for NRC
and EPA consultation for certain sites when, at the time of license
termination, (1) groundwater contamination exceeds EPA-permitted
levels; (2) NRC contemplates restricted release or alternate criteria
for release of the site; and/or (3) residual radioactive soil
concentrations exceed levels defined in the MOU.
SUPPLEMENTARY INFORMATION: The MOU responds to a 1999 report from the
House Committee on Appropriations that stated: ``in the interest of
ensuring that sites do not face dual regulation, the Committee strongly
encourages both agencies to enter into an MOU which clarifies the
circumstances for EPA's involvement at NRC sites when requested by the
NRC.'' The MOU also is responsive to a Government Accounting Office
report issued in 2000. The MOU does not fully meet the intent of the
Appropriations Committee because the threat of dual regulation remains
for certain licensees. Thus, although the MOU reduces dual
jurisdiction, the NRC will continue efforts to seek legislation that
would eliminate the possibility of dual regulation of all NRC
decommissioning licensees.
The MOU does not impose any new requirements on NRC licensees and
will reduce the involvement of EPA with NRC licensees who are
decommissioning. Most sites are expected to meet the NRC criteria for
unrestricted use, and NRC believes that only a few sites will have
groundwater or soil contamination in excess of the levels specified in
the MOU which trigger consultation with EPA. If there are other
hazardous materials on the site, EPA may be involved in cleanup.

I. Introduction
The Environmental Protection Agency (EPA) and the Nuclear
Regulatory Commission (NRC), in recognition of their mutual commitment
to protect the public health and safety and the environment, are
entering into this Memorandum of Understanding (MOU) in order to
establish a basic framework for the relationship of the agencies in the
radiological decommissioning and decontamination of NRC-licensed sites.
Each Agency is entering into this MOU in order to facilitate decision-
making. It does not establish any new requirements or rights on parties
not subject to this agreement.
II. Purpose
The purpose of this MOU is to identify the interactions of the two
agencies for the decommissioning and decontamination of NRC-licensed
sites and to indicate the way in which those interactions will take
place. Except for section VI, addressing corrective action under the
Resource Conservation and Recovery Act (RCRA), this MOU is limited to
the coordination between EPA, when acting under its Comprehensive
Environmental Response, Compensation and Liability act (CERCLA)
authority, and NRC, when a facility licensed by the NRC is undergoing
decommissioning, or when a facility has completed decommissioning, and
the NRC has terminated its license. It continues a basic policy of EPA
deferral to NRC decision-making in the decommissioning of NRC-licensed
sites except in certain circumstances, and establishes the procedure to
govern the relationship between the agencies in connection with the
decommissioning of sites at which those circumstances arise.
III. Background
An August 3, 1999, report (106-286) from the House Committee on
Appropriations to accompany the bill accompany the bill covering EPA's
FY 1999 Appropriations/FY 2000 budget request states:
Once again the Committee notes that the Nuclear Regulatory
Commission (NRC) has and will continue to remediate sites under its
jurisdiction to a level that fully protects public health and safety,
and believes that any reversal of the long-standing policy of the
Agency to defer to the NRC for cleanup of NRC's licensed sites is not a
good use of public or private funds. The interaction of the EPA with
the NRC, NRC licensees, and others, with regard to sites being
remediated under NRC regulatory requirements--when not specifically
requested by the NRC--has created stakeholder concerns regarding the
authority and finality of NRC licensing decisions, the duration and
costs of site cleanup, and the potential future liability of parties
associated with affected sites. However, the Committee recognizes that
there may be circumstances at specific NRC licensed sites where the
Agency's expertise may be of critical use to the NRC. In the interest
of ensuring that sites do not face dual regulation, the Committee
strongly encourages both agencies to enter into an MOU which clarifies
the circumstances for EPA's involvement at NRC sites when requested by
the NRC. The EPA and NRC are directed to report to the Committee on
Appropriations no later than May 1, 2000, on the status of the
development of such an MOU.
Since September 8, 1983, EPA has generally deferred listing on the
CERCLA National Priorities List (NPL) those sites that are subject to
NRC's licensing authority, in recognition that NRC's actions are
believed to be consistent with the CERCLA requirement to protect human
health and the environment. However, as EPA indicated in the Federal
Register notice announcing the policy of CERCLA deferral to NRC, if EPA
``determines that sites which it has not listed as a matter
[[Page 65376]]
of policy are not being properly responded to, the Agency will consider
listing those sites on the NPL'' (see 48 FR 40658).
EPA reaffirms its previous 1983 deferral policy. EPA expects that
any need for EPA CERCLA involvement in the decommissioning of NRC
licensed sites should continue to occur very infrequently because EPA
expects that the vast majority of facilities decommissioned under NRC
authority will be decommissioned in a manner that is fully protective
of human health and the environment. By this MOU, EPA agrees to a
deferral policy regarding NRC decision-making without the need for
consultation except in certain limited circumstances as specified in
paragraphs V.C.2 and V.C.3.
One set of circumstances in which continued consultation should
occur, pursuant to the procedures defined herein, relates to sites at
which the NRC determines during the license termination process that
there is radioactive ground-water contamination above certain limits.
Pursuant to its License Termination rule, NRC applies a dose criterion
that encompasses all pathways, including ground water. In its cleanup
of sites pursuant to CERCLA, by contrast, EPA customarily establishes a
separate ground-water cleanup standard in which it applies certain
Maximum Contaminant Levels (MCLs, found at 40 CFR 141) promulgated for
radionuclides and other substances pursuant to the Safe Drinking Water
Act. NRC has agreed in this MOU to consult with EPA on the appropriate
approach in responding to the circumstances at particular sites with
ground-water contamination at the time of license termination in excess
of EPA's MCLs or those sites for which NRC contemplates either
restricted release or the use of alternate criteria for license
termination, or radioactive contamination at the time of license
termination exceeds the corresponding levels in Table 1 as provided in
section V.C.2.
IV. Principles
In carrying out their respective responsibilities, the EPA and the
NRC will strive to:
1. Establish a stable and predictable regulatory environment with
respect to EPA's CERCLA authority in and NRC's decommissioning of
contaminated sites.
2. Ensure, to the extent practicable, that the responsibilities of
the NRC under the AEA and the responsibilities of EPA under CERCLA are
implemented in a coordinated and consistent manner.
V. Implementation
A. Scope
This MOU is intended to address issues related to the EPA
involvement under CERCLA in the cleanup of radiologically contaminated
sites under the jurisdiction of the NRC. EPA will continue its CERCLA
policy of September 8, 1983, which explains how EPA implements deferral
decisions regarding listing on the NPL of any sites that are subject to
NRC's licensing authority. The NRC's review of sites under NRC
jurisdiction indicates that few of these sites have radioactive ground-
water contamination in excess of the EPA's MCLs. At those sites at
which NRC determines during the license termination process that there
is radioactive ground-water contamination above the relevant EPA MCLs,
NRC will consult with EPA and, if necessary, discuss with EPA the use
of flexibility under EPA's phased approach to addressing ground-water
contamination. NRC has agreed in this MOU to consult with EPA on the
appropriate approach in responding to the circumstances at particular
sites where ground-water contamination will exceed EPA's MCLs, NRC
contemplates either restricted release or the use of alternate criteria
for license termination, or radioactive contamination at the time of
license termination exceeds the corresponding levels in Table 1 as
provided in Section V.C.2.
B. General
Each agency will keep the other agency generally informed of its
relevant plans and schedules, will respond to the other agency's
requests for information to the extent reasonable and practicable, and
will strive to recognize and ameliorate to the extent practicable any
problems arising from implementation of this MOU.
C. NRC Responsibilities
1. NRC will continue to ensure remediation of sites under its
jurisdiction to a level that fully protects public health and safety.
2. For NRC-licensed sites at which NRC determines during the
license termination process that there is radioactive ground-water
contamination in excess of EPA's MCLs, or for which NRC contemplates
either restricted release (10 CFR 20.1403) or the use of alternate
criteria for license termination (10 CFR 20.1404), NRC will seek EPA's
expertise to assist in NRC's review of a decommissioning or license
termination plan. In addition, NRC will consult with EPA if either the
planned level of residual radioactive soil concentrations in the
proposed action or the actual residual level of radioactive soil
concentrations found in the final site survey exceed the radioactive
soil concentration in Table 1. With respect to all such sites, the NRC
will consult with EPA on the application of the NRC decommissioning
requirements and will take such action as the NRC determines to be
appropriate based on its consultation with EPA. For example, if NRC
determines during the license termination process that there will be
radioactive ground-water contamination in excess of EPA's MCLs at the
time of license termination, then NRC will discuss with EPA the use of
flexibility under EPA's phased approach for addressing ground-water
contamination. If NRC does not adopt recommendations provided by the
EPA, NRC will inform EPA of the basis for its decision not to do so.
3. NRC will defer to EPA regarding matters involving hazardous
materials not under NRC's jurisdiction.
D. EPA Responsibilities
1. If the NRC requests EPA's consultation on a decommissioning plan
or license termination plan, EPA will provide, within 90 days of NRC's
notice to EPA, written notification of its views on the matter.
2. Consistent with this MOU, EPA agrees to a policy of deferral to
NRC decision making on decommissioning without the need for
consultation on sites other than those presenting the circumstances
described in sections V.C.2 and V.C.3. The agencies will consult with
each other pursuant to the provisions of this MOU with respect to those
sites presenting the circumstances described in sections V.C.2 and
V.C.3. EPA does not expect to undertake CERCLA actions related to
radioactive contamination at a site that has been decommissioned in
compliance with the NRC's standards, including a site addressed under
section V.C.2, despite the agencies decision to engage in consultation
on such sites. EPA's deferral policy, and its expectation of not taking
CERCLA action, continues to apply to sites that are covered under
section V.C.2.
3. For NRC-licensed sites presenting the circumstances described in
section V.C.2 and for which NRC has not adopted the EPA recommendation,
EPA will consult with NRC on any CERCLA actions EPA expects to take if
EPA does not agree with the NRC's decision.
4. EPA will resolve any CERCLA concerns involving hazardous
substances outside of NRC's jurisdiction at NRC licensed sites,
including concerns involving hazardous
[[Page 65377]]
constituents that are not under the authority of NRC. As provided in
section V.D.2, EPA under CERCLA will defer or consult with NRC as
appropriate regarding matters involving AEA materials under NRC's
jurisdiction.
E. Other Provisions
1. Nothing in this MOU shall be deemed to establish any right nor
provide a basis for any action, either legal or equitable by any
person, or class of persons challenging a government action or failure
to act.
2. Each agency will appoint a designated contact for implementation
of this MOU. The designated individuals will meet at least annually or
at the request of either agency to review NRC-licensed sites that meet
the criteria for consultation pursuant to section V.C.2. The NRC
designated contact is the Director, Office of Nuclear Materials Safety
and Safeguards, and the EPA designated contact is the Director, Office
of Emergency and Remedial Response, or as each designee delegates.
3. This MOU will remain in effect until terminated by the written
notice of either party submitted six months in advance of termination.
4. Within six months of the execution of this MOU, each party will
revise its guidance to its Headquarters and Regional Offices to reflect
the terms of this MOU.
5. If differences arise that cannot be resolved by senior EPA and
NRC management within 90 days, then either senior EPA or NRC management
may raise the issue to their respective agency head.
VI. Corrective Action Under RCRA
Some NRC sites undergoing decommissioning may be subject to cleanup
under RCRA corrective action authority. This authority, administered
either by EPA or authorized states, requires cleanup of releases of
hazardous waste or constituents at hazardous waste treatment, storage
or disposal facilities. NRC sites subject to RCRA corrective action
will be expected to meet RCRA cleanup standards for chemical
contamination within EPA's jurisdiction. EPA Office of Solid Waste's
policy is to encourage regional and State program implementers to
coordinate RCRA cleanups with decommissioning, as appropriate, at those
NRC sites subject to EPA's corrective action authority.\1\
---------------------------------------------------------------------------
\1\ See letter from Elizabeth Cotsworth, Acting Director, Office
of Solid Waste to James R. Roewer, USWAG, dated March 5, 1997.
---------------------------------------------------------------------------
EPA will continue to support coordination of cleanups under the
RCRA corrective action program with decommissioning at NRC sites
consistent with its March 5, 1997 policy. In addition, under RCRA the
majority of States are authorized to implement the corrective action
requirements. States are not signatories to this MOU; however, EPA will
encourage States to act in accordance with this policy where they have
responsibility for RCRA corrective action at NRC sites undergoing
decommissioning.
Items 1 and 3 of the ``Other Provisions'' of section V.E. apply to
this section.
