I.      EXECUTIVE SUMMARY

       On May 13, 1998, the U.S. Environmental Protection Agency (EPA) certified that the
Waste Isolation Pilot Plant (WIPP) can safely contain transuranic (TRU) radioactive waste and
complies with EPA's radioactive waste disposal standards. On March 26, 1999, the WIPP
facility began receiving radioactive waste. WIPP is the nation's first geologic facility designed
for permanent disposal of TRU radioactive waste that was generated as a result of U.S. defense-
related activities.

       EPA has an ongoing oversight role at the WIPP. We independently verify that the
Department of Energy (DOE) maintains and operates the facility in a safe manner, and that the
facility continues to comply with our radioactive waste disposal standards.  EPA's main
oversight activities include:
       • Recertifying the safety of the WIPP;
       • Conducting audits and inspections;  and
       • Evaluating changes in activities and conditions at WIPP.

       On March 26, 2004, EPA received DOE's first Compliance Recertification Application
(CRA).  A Federal Register notice announcing the receipt of the CRA and opening the public
comment period was published on May 24, 2004. The entire CRA as well as all supporting
documentation and correspondence between EPA and DOE are posted on the EPA website.
During 2004, EPA began reviewing the application for completeness and considering public
comment on the CRA.

       EPA continues to audit, inspect and approve DOE's waste characterization and quality
assurance programs. As of the end of fiscal year 2004, EPA has approved the following TRU
waste sites: (1) Hanford  Site in Washington, (2) Idaho National Engineering and Environmental
Laboratory (INEEL), (3)  Los Alamos National Laboratory (LANL), (4) Rocky Flats
Environmental Technology Site (RFETS) in Colorado, and (5) Savannah River Site (SRS) in
South Carolina. In addition, the Nevada Test Site (NTS), Lawrence Livermore National
Laboratory (LLNL), Argonne National Laboratory-East (ANL-E) in Illinois, LANL, and SRS
were approved to dispose of waste characterized by the Central Characterization Project (CCP)
at WIPP.

       Highlights from EPA's WIPP program for Fiscal Year (FY) 2004 include:

•  EPA conducted fourteen audits of WIPP Quality Assurance organizations and determined
   that they had been properly established or maintained.

•  EPA conducted eleven inspections of waste characterization activities at DOE waste
   generator sites. The inspections were conducted to ensure continued compliance with EPA
   regulations at approved sites and to approve new waste characterization programs and
   activities.

•  In January 2004, EPA approved DOE's general framework for the characterization of
   remote-handled (RH) TRU waste. DOE must still develop site-specific procedures that

-------
implement the general framework for RH and obtain EPA approval of RH WC activities
prior to disposal at WIPP.

In 2004, EPA inspected the WIPP site and verified compliance with the monitoring and
waste emplacement requirements of the certification, and with Subpart A requirements of 40
CFR Part 191.

In March 2004, EPA approved DOE's request to dispose of compressed waste (or super-
compacted) from the INEEL at WIPP.  EPA's approval of DOE's concept addressed the
impact of compressed waste on the performance of the repository.  Prior to the actual
disposal of compressed waste, DOE must still demonstrate the ability to adequately
characterize compressed waste.

Finalized changes to 40 CFR 194 to increase EPA's efficiency with inspection priorities,
scheduling and resources and to enhance the public participation process by allowing public
comment on EPA's proposed approval of waste characterization programs in Santa Fe, New
Mexico to discuss the components of DOE's Compliance Recertification Application and our
recertification process.

Completed evaluation of DOE's FY 2004 Annual Change Report and notified DOE that the
changes to the WIPP program were not significant and did not require a modification,
suspension, or revocation of the WIPP  Certification Decision.

In FY 2004, EPA funded 10 in-house staff positions at EPA Headquarters and EPA's Region
6 office in Dallas, TX and obligated contract dollars in the amount of approximately
$850,000 to fulfill our responsibilities under the WIPP LWA.

-------
II.     INTRODUCTION

       With this report the U.S. Environmental Protection Agency (EPA, Agency or we)
complies with the requirement in Section 23(a)(2) of the Waste Isolation Pilot Plant Land
Withdrawal Act, Pub. L. No. 102-579 (Act or LWA), which requires EPA to submit an annual
report to the Congress "on the status of, and resources required for the fulfillment of the
Administrator's responsibilities under this Act."

       The Act, as amended in 1996, gives EPA the authority to oversee many of the
Department of Energy's (DOE) activities at Waste Isolation Pilot Plant (WIPP) throughout the
facility's operational and decommissioning phases. The WIPP, located in southeastern New
Mexico, is operated by DOE as a long-term geologic disposal facility for transuranic (TRU)
radioactive waste. TRU waste is long-lived radioactive waste generated as by-products from
nuclear weapons production and decommissioning.

       The Act requires EPA to take the following regulatory actions:

•             Issue Radioactive Waste Disposal Standards
       Develop environmental radiation protection standards for the disposal of spent nuclear
       fuel, high-level waste and TRU radioactive waste, which will apply to all potential
       disposal sites except the site identified by Section 113(a) of the Nuclear Waste Policy
       Act, as amended (completed 09/19/1985, 40 CFRPart 191).

              Develop Compliance Criteria
       Establish criteria to determine whether the WIPP will comply with the Agency's
       radioactive waste disposal regulations (completed 02/01/1986, 40 CFRPart 194).

•             Conduct a Compliance Certification
       Certify by rulemaking whether or not the WIPP complies with the Agency's radioactive
       waste disposal regulations (completed 05/18/1998, 63 FR 27354).

•             Recertify Periodically
       Determine every five years whether or not the WIPP facility continues to be in
       compliance with the Agency's radioactive waste disposal regulations (recertification
       process began in March 2004).

       In addition to these regulatory actions, EPA must determine whether documentation
submitted by DOE pursuant to Section 9(a)(2) of the Act demonstrates continued compliance
with environmental laws, regulations, and permit requirements as described in Section 9(a)(l) of
the Act.

       This report summarizes EPA's activities during FY 2004 (October 1, 2003 - September
30, 2004) to fulfill its responsibilities under the WIPP  LWA and to provide  independent
regulatory oversight of the disposal of radioactive waste at WIPP. Beginning in 1992 with the
passage of the WIPP LWA, EPA has submitted such reports to Congress each year. For a

-------
description of EPA's WIPP activities and accomplishments prior to FY 2004, please refer to
these previous reports.

-------
III.    EPA'S WIPP REGULATORY AND OVERSIGHT ACTIVITIES

A. Management

       The Office of Radiation and Indoor Air (ORIA), located in the Office of Air and
Radiation (OAR), is charged with the primary responsibility for implementing the Act and
ensuring that EPA's oversight responsibilities are performed in a timely and scientifically-
credible manner. Other EPA offices with significant roles are the Office of General Counsel
(OGC) and EPA Region 6.  Region 6, together with the State  of New Mexico, regulates the
WIPP's compliance with the Resource Conservation and Recovery Act (RCRA). Region 6 also
oversees DOE's demonstration of compliance with all other applicable Federal environmental
laws.

       Within ORIA, the Center for Federal Regulations in the Radiation Protection Division
(RPD) executes most of EPA's responsibilities under the Act.  RPD's Outreach Team leads
EPA's WIPP public outreach efforts. Staff-level implementation of the Act is coordinated
through an intra-agency work group established by RPD.

B. Resources

       The Act authorized DOE to transfer funds appropriated for environmental restoration and
waste management to the EPA through the year 2001 for fulfilling the responsibilities of the
Administrator under the Act. Since 2001,  DOE, although not required, has transferred multi-
year funds to EPA through interagency agreements (IAG) to support our oversight of the WIPP.
In FY 2004, under the current IAG, DOE provided funds to support EPA's continuing regulatory
oversight of the WIPP, including recertification, conducting quality assurance (QA) and waste
characterization (WC) inspections and attending various WIPP-related technical meetings.  The
resources required to fulfill EPA's responsibilities under the Act are highly dependent on DOE's
schedule and can fluctuate greatly from year to year because of the number of sites requiring
inspection each year, proposed DOE changes to WIPP, and the required recertification every five
years.

C. Continuing Compliance

       In 1998, EPA certified that the WIPP will comply with 40 CFR Part 191 and 40 CFR Part
194, thus allowing the opening and operation of the WIPP.  EPA continues to monitor the
WIPP's compliance with EPA's radioactive waste disposal standards. This oversight includes
conducting audits and site inspections, reviewing annual change reports, and determining every
five years if the WIPP should be recertified.

       Recertification

       In FY 2004, EPA began preparations to conduct the first "recertification" of the WIPP to
determine the WIPP's continued compliance with the disposal regulations. Under the WIPP
LWA, DOE must submit documentation of continued compliance no later than March 2004, five
                                          6

-------
years after initial receipt of waste at the WIPP.  On March 26, 2004, DOE submitted the
Compliance Recertification Application (CRA). EPA began its review of the CRA by assessing
the completeness of the application. In FY 2004 EPA sent three letters to DOE requesting
additional information for the CRA.

       EPA's requests for additional information and DOE reports are available in EPA's
dockets, and a public comment period will be opened on this material until the CRA is deemed
complete by EPA. The Agency will conduct the recertification evaluation based on the results of
our continuous oversight of the WIPP, on complete documentation provided by DOE, and on
public input. The Agency's decision on recertification will be announced in the Federal
Register. EPA must issue its decision on recertification no more than six months after the
Agency determines that DOE's recertification application is complete. EPA will conduct
recertifications every five years until the end of the decommissioning phase.

       Quality Assurance Audits

       EPA requires DOE (40 CFR Part 194.22) to establish and implement a QA program for
all items and activities that are important to the  containment of TRU waste in the disposal
system. DOE's QA program must implement the applicable requirements of specific Nuclear
Quality Assurance (NQA) standards issued by the American Society of Mechanical Engineers
(ASME). QA is a process for DOE to independently verify the reliability of items and activities,
such as technical data and analyses that are important to the  long-term containment of TRU
waste.

       The Agency verified that DOE established these QA requirements in the Quality
Assurance Program Document (QAPD) included in the Compliance Certification Application for
the WIPP. The QAPD is the documented QA plan for the WIPP project, as a whole, to comply
with the NQA requirements. The QAPD is maintained by the QA organization of DOE's
Carlsbad Field Office (CBFO), which has the authority to audit all other organizations associated
with TRU waste disposal at the WIPP to ensure that their lower-tier quality assurance programs
establish and implement the applicable requirements of the QAPD. The  other DOE
organizations such as the generator sites, which characterize waste for disposal in the WIPP,
must have site-specific QA plans.

       Once EPA has approved the QA program of a particular site, the Agency audits it on an
annual basis to verify that the program is properly maintained.  In 2004, EPA completed QA
audits at the five major waste generator sites that are approved to ship waste to the WIPP and
found that all five were properly maintaining their QA programs for WC.

       Site Inspections

       There are approximately 20 major sites across the country that store TRU waste. CBFO
determines which sites are eligible to ship waste to the WIPP and audits them for compliance
with DOE requirements. As CBFO certifies each site, EPA inspects the site to determine
whether it also meets EPA's certification requirements.

-------
       During FY 2004, EPA approved four waste characterization programs as follows: (1)
solid waste from the Idaho National Engineering and Environmental Laboratory's (INEEL)
Advanced Mixed Waste Treatment Project (AMWTP), (2) debris waste from the Lawrence
Livermore National Laboratory's (LLNL) Central Characterization Project (CCP), (3) debris
waste from the Los Alamos National Laboratories (LANL) CCP, and (4) soils from the Rocky
Flats Environmental Technology Site (RFETS).  DOE's CCP augments the sites' ability to
characterize certain waste in an expeditious manner.  In FY 2004, EPA also inspected four sites
for continued compliance with their previously approved WC programs and waste streams
approved for WIPP disposal:  (1) AMWTP, (2) Hanford, (3) RFETS, and (3) SRS CCP. In
addition, EPA inspected the TRU waste tracking system maintained at DOE's CBFO to track
waste containers and their contents from generator sites to WIPP for placement in the repository.

       In January 2004, EPA approved DOE's general framework for the characterization of
remote-handled (RH) TRU waste. DOE must still develop site-specific procedures that
implement the general framework for RH and obtain EPA approval of RH WC  activities prior to
disposal at WIPP.

       In FY 2004, DOE stopped shipment of waste on three occasions: once each from LANL,
Hanford and INEEL. First, when DOE found that LANL had been characterizing debris waste
using radioassay equipment with calibration errors.  DOE withdrew LANL's site certification
and consulted EPA during its development of corrective measures. EPA evaluated information
pertinent to the affected waste containers and equipment and concluded that these waste
containers are adequately characterized. Second, when DOE found that EPA had not approved
Hanford's solid waste from the Plutonium Finishing Plant (PFP), and CBFO had erroneously
certified its disposal at WIPP. In the third instance, DOE found that some transuranic waste
from INEEL had been shipped to WIPP and had not been included in INEEL's  statistical
sampling population. This resulted in one shipment being stopped enroute and  returned to
INEEL and stoppage of all shipments from INEEL until a review was conducted and correction
actions were put in place. In all instances, EPA allowed the waste to remain underground
because it was not thought to be an additional risk to human health and the environment. DOE
has taken action to avoid similar occurrences in the future.

       On July 16, 2004, EPA finalized 40  CFR 194 requirements for site inspection and
approval process. Under the new rule,  EPA must conduct baseline inspections at DOE's TRU
waste generator/storage sites.  As part of the baseline inspections, EPA must assign a tier to each
component of the TRU waste characterization processes at the site. EPA can assign Tier 1
(requires reporting by a site of the proposed changes) or Tier 2 (requires reporting of changes to
EPA but allows implementation of changes without prior EPA approval). The new rule also
requires EPA to  seek public comment on EPA's pending approval  and docket site inspection
report and DOE-provided documents. EPA can issue site approval only after consideration of
public comment.  EPA's waste characterization inspections performed in FY 2004 were subject
to the site inspection and approval process promulgated in 1998. These changes provide
equivalent or improved oversight and better prioritization of technical issues in  EPA inspections
to evaluate WC activities at DOE's WIPP waste generator sites; and offer more direct public
input into EPA's decisions regarding which waste can be disposed of at WIPP.

-------
       In FY 2005, the Agency will conduct site inspections and waste characterization program
approvals in accordance with the new rule.  In addition, EPA will continue to conduct annual
inspections of the WIPP site to ensure waste monitoring and emplacement activities are in
compliance with the certification, as well as with 40 CFR Part 191, SubpartA requirements,
dealing with waste storage and management.

       Approval of INEEL Compressed Waste

       In December 2003, DOE submitted  a request to dispose of INEEL waste that will be
compressed or supercompacted. DOE plans to supercompact 55-gallon drums of waste into
"pucks", and place three to five pucks in a 100-gallon overpack drum that will be shipped to
WIPP. In addition to having different structural characteristics than typical WIPP waste, the
INEEL supercompacted waste will have higher than average amounts of cellulosic, plastic and
rubber (CPR) material. Because of these differences, EPA undertook a thorough review at
DOE's request. Based on the additional analysis, EPA concluded that the supercompacted waste
from INEEL fits within the anticipated WIPP waste envelope and the waste characteristics are
encompassed in the current performance assessment. EPA is requiring DOE to place additional
magnesium oxide with the compacted waste to maintain the current safety factor.

       Change Reports

       EPA requires at 40 CFR Part 194.4(b)(4) that DOE report any planned or unplanned
changes in activities or conditions on which EPA's Compliance Certification decision was based.
EPA provided DOE with reporting guidance on  September 30, 1998 and placed it in EPA's
public dockets. EPA reviews information about the changes and determines whether the initial
certification should be modified, suspended, or revoked. Often, DOE makes changes to their
activities to make improvements or increase efficiency, and in many cases, these changes are
insignificant. The Agency may ask for public comment to assist in its review. Records of
changes to WIPP that EPA has reviewed since 1998 have been placed in the public dockets.

       DOE submitted its 2003 report to EPA on November 13, 2003.  EPA reviewed this report
and requested additional information. EPA notified DOE on August 10, 2004, that the changes
did not require a modification, suspension, or revocation of EPA's certification decision. Most
of the changes described in the report were  associated with modifications to written plans and
procedures, required monitoring activities, and upcoming changes that DOE was considering.
We also approved a change in the reporting dates.  Future annual change reports will cover
changes from July 1 through June 30 to allow for additional time to compile the report and for
the inclusion of more detailed information and analyses.

-------
D. Alternative Provisions in the WIPP Compliance Criteria

       Since EPA's initial certification in 1998, EPA has conducted dozens of
independent technical reviews, inspections of the WIPP facility, and inspections of the
DOE's TRU waste generator sites around the United States to verify compliance with our
WIPP disposal regulations. Based on this experience, EPA determined that certain
sections in the Compliance Criteria related to inspections of TRU waste generator sites
needed to be revised.  The Agency's goal was to apply experience regulating the waste
generator sites to improve the Compliance  Criteria, maintaining equivalent regulatory
controls, and focusing resources where they may be most effective.

       Following the process established in 40 CFR Part 194.6, EPA finalized the
following alternative provisions in the Federal Register on July 16, 2004:

   •   change the WC program approval procedures to increase EPA's efficiency with
       inspection priorities,  scheduling and resources;

   •   enhance the public participation process by allowing public comment on EPA's
       proposed approval of WC programs;

   •   add a streamlined process to allow the Administrator to  make minor revisions to
       the Compliance Criteria in a timely fashion;

   •   allow DOE to submit compliance applications and reference materials in
       alternative (non-paper) format; and

   •   make other minor changes to the criteria for consistency with the changes listed
       above.

E. 40 CFR Part 191, Subpart A: Standards for the Management and Storage of
   Spent Nuclear Fuel, High-Level and Transuranic Waste

       Subpart A of 40 CFR Part 191  contains EPA's environmental standards for the
management and storage of spent fuel, high-level  and TRU waste at disposal facilities
operated by DOE. For the WIPP, these standards  apply to activities during the
operational period of the facility, including when waste arrives  at the above-ground
portion of the WIPP, is unloaded and prepared for emplacement in the underground
repository,  and is lowered down the shaft and emplaced in the underground disposal
rooms.

       To implement Subpart A, EPA and DOE are following EPA's WIPP Subpart A
guidance, issued in January 1997, which  interprets the standard specifically for the WIPP.
(See 62 FR 9188.) As recommended by this guidance document,  DOE notified EPA
when initial startup of the WIPP was expected.  In March 1999, prior to start-up
occurring,  EPA performed an on-site inspection of the WIPP to verify DOE's start-up
readiness and its ability to capture, measure, and calculate any potential releases during
                                       10

-------
waste disposal operations. EPA inspections found that the WIPP was ready to receive
waste and that DOE was able to monitor compliance with Subpart A. Thereafter, EPA
has performed Subpart A inspections on an annual basis.

       In June 2004, EPA performed a Subpart A inspection to verify DOE's continued
compliance with the Subpart A requirements.  The inspectors found that DOE, through its
contractor Washington TRU Solutions, had an effective radiation sampling program,
calculated doses estimates adequately, and that the procedures and documentation were
technically adequate.

       In the future, DOE will continue to monitor the WIPP facility to detect any
potential releases of radioactive materials. If any releases occur and cause radiation
doses exceeding the Subpart A limits, then DOE will implement a "remedial plan" and
submit monthly reports to EPA. Otherwise, DOE will report on compliance with Subpart
A as part of the Biennial Environmental Compliance Report (BECR).

F. Compliance with the Resource Conservation and Recovery Act

       Substantial portions of the wastes proposed for disposal at the WIPP are mixed
waste, which contain both hazardous waste subject to the RCRA and radioactive waste
subject to the Atomic Energy Act (AEA). WIPP, therefore, must also comply with
regulations  developed under RCRA. This section describes EPA's implementation of
RCRA requirements.

       EPA authorized the State of New Mexico to carry out the State's base RCRA
program and the State's mixed waste program in lieu of the respective Federal programs.
Therefore, the State issued and implements the RCRA permit for the WIPP. EPA's
Region 6 office provides oversight and technical assistance to the State in implementing
this permit.

       Under the permit, the State of New Mexico audits the DOE inspections of the
generator sites contributing waste to the WIPP. The State approves each site that
demonstrates adequate compliance with the requirements in the permit and monitors
DOE's audit program and documentation.

G. Compliance With Other Federal Environmental Laws

       The LWA requires DOE to submit documentation to EPA - and, where
applicable, the State of New Mexico - every two years to demonstrate the WIPP's
compliance with all applicable Federal  environmental laws, regulations, and permit
requirements, including:  the radioactive waste management and storage regulations (40
CFR Part 191, Subpart A); the Clean Air Act; the Toxic Substances Control Act; the
Comprehensive Environmental Response, Compensation, and Liability Act; the Solid
Waste Disposal Act;  and the Safe Drinking Water Act. This  documentation must be
submitted throughout the disposal and decommissioning phases of the WIPP. DOE
provides this information to EPA in its  "Biennial Environmental Compliance Report
                                       11

-------
(BECR)."  EPA (and, where applicable, the State of New Mexico) must make a
determination of compliance with these statutes, regulations, and permit requirements
within six months of receiving DOE's BECR.  If EPA determines that the WIPP does not
comply with any applicable Federal law, regulation or permit requirement, the Agency
will require DOE to develop a remedial plan within six months of this determination.

      DOE submitted the BECR for 2002-2004 to EPA on October 31, 2004. EPA
determined that based on the report, WIPP remains in compliance with all applicable
Federal environmental laws, regulations, and permit requirements. EPA expects DOE to
submit the BECR for the 2004-2006 period in October 2006.
                                      12

-------
IV.    COMMUNICATION AND CONSULTATION ACTIVITIES

       EPA continues to inform interested parties about its WIPP oversight functions and
encourage public participation in the Agency's oversight role and activities.

       In July 2004, EPA sponsored public meetings in Carlsbad, Santa Fe and
Albuquerque, New Mexico, to provide information about the recertification review
process and timeline, and the content of DOE' s compliance recertification application.
The meetings offered presentations and poster sessions, and facilitated discussions on
topics related to WIPP recertification.  At the request of the stakeholders, DOE fully
participated in these meetings. Meeting participants were invited to provide comments to
EPA for our consideration during review of DOE' s WIPP application. Public
participants commented that the meeting development process, format and execution
were a good model for public involvement.

       EPA's toll-free WIPP Information Line (1-800-3 31 -WIPP) provides up-to-date,
recorded information about public hearings and meetings, publications, and other WIPP
activities.  Callers listen to recorded messages, add their name to the WIPP mailing list,
request a WIPP publication, or leave a question for EPA staff.

       In an ongoing effort to keep the public well-informed, EPA regularly places all
pertinent information about the WIPP in the official docket at EPA Headquarters in
