Abstract
The Environmental Protection Agency (EPA or the Agency) seeks public comment on a Planned Change Request (PCR) recently submitted by the U.S. Department of Energy (DOE) to modify the Waste Isolation Pilot Plant (WIPP) to replace lost disposal capacity resulting from the 2014 radiological incident and ground control issues throughout WIPP's operational history. The proposed change will involve adding two additional waste panels to the west of the current repository and connecting those panels to the existing facility via the west main access drifts (tunnels) currently under construction. EPA is soliciting public comments on both the DOE application and on what EPA should consider in its evaluation of DOE's PCR.

Public information session. EPA will be hosting public information
sessions during the comment period in the Carlsbad, NM and Santa Fe, NM
locales. Additional details about timing and the registration process
for the information sessions will be shared on EPA's WIPP website at
<a href="https://www.epa.gov/radiation/wipp-news">https://www.epa.gov/radiation/wipp-news</a>. This information will also be
distributed by the WIPP-NEWS email listserv. The information sessions
will include presentations from both EPA and DOE regarding the content
and review of the PCR. Additionally, there will be a facilitated
discussion surrounding questions EPA plans to address/has addressed
with DOE related to the PCR. Participants will also have an opportunity
to ask clarifying questions and provide comments on the contents of the
PCR.
I. Background
The Waste Isolation Pilot Plant (WIPP) is a transuranic (TRU)
radioactive waste disposal system developed by the DOE that is located
near Carlsbad in southeastern New Mexico. TRU radioactive waste is
emplaced about 650 meters (2,150 feet) underground in an ancient layer
of salt that will eventually ``creep,'' encapsulate, and isolate the
waste from the surrounding environment. The 1992 WIPP Land Withdrawal
Act (Pub. L. 102-579) (LWA) limits radioactive waste disposal in the
WIPP to TRU radioactive wastes generated by defense-related
activities.\1\ The WIPP LWA provides EPA with authority to oversee and
regulate the WIPP. The WIPP must meet EPA's generic radioactive waste
disposal standards at 40 CFR part 191, subparts B and C. These
standards limit releases of radioactive materials from disposal systems
for radioactive waste and require implementation of measures to provide
confidence for compliance with the radiation release limits.
Additionally, the regulations limit radiation doses to members of the
public and protect ground water resources by establishing maximum
concentrations for radionuclides in ground water.
---------------------------------------------------------------------------
\1\ TRU waste is defined as waste containing more than 100 nano-
curies per gram of alpha-emitting radioactive isotopes, with half-
lives greater than twenty years and atomic numbers greater than 92.
---------------------------------------------------------------------------
In 1996, the Agency issued the WIPP Compliance Criteria, which are
located at 40 CFR part 194, as mandated by WIPP LWA, section 8(c).\2\
DOE submitted the initial WIPP Compliance Certification Application
(CCA) in 1996. The Agency then issued the certification decision on May
18, 1998, determining that the WIPP met the standards for radioactive
waste disposal. Since the 1998 certification decision, EPA has
conducted ongoing independent technical reviews, certification/
recertifications, and inspections of all WIPP activities related to
compliance with the Agency's disposal regulations. The WIPP has been
recertified four times since the initial CCA in 1996, with the most
recent recertification decision occurring in 2022.\3\
---------------------------------------------------------------------------
\2\ 61 FR 5224-5245 (February 9, 1996).
\3\ 87 FR 26126 (May 3, 2022).
---------------------------------------------------------------------------
As part of the original design of the WIPP repository in the
initial CCA, the underground waste disposal region at WIPP is divided
into panels. A panel is a group of rooms mined into the salt, connected
by tunnels called drifts. EPA certified the WIPP in 1998 and most
recently recertified the WIPP in 2022 based on a planned footprint of
10 waste panels.
On March 14, 2024, EPA received a planned change request (PCR) from
DOE per 40 CFR 194.4(b)(3) that seeks the Agency's approval to add two
replacement waste panels to the west of the current repository. These
two panels, 11 and 12, are being constructed to replace waste disposal
volume that was lost in panels 7 and 9 due to the 2014 radiological
release that contaminated the south end of the repository.\4\
Additionally, panels 1 and 2 were not completely filled due to ground
control issues from being kept open so long before waste was emplaced.
DOE has calculated that to replace the volume lost, 1.7 panels of waste
volume will be needed, rounded up to 2 panels for construction.\5\ DOE
also states that the waste volume with panels 11 and 12 will not exceed
the LWA waste disposal volume limit. The PCR contains a performance
assessment DOE has conducted to support a demonstration that the
repository will continue to meet the numeric release limits of EPA's
disposal regulations for the WIPP. As part of the performance
assessment, DOE calculated releases based on a repository design of 19
panels, which is the anticipated WIPP repository configuration at the
time of closure. With this PCR, DOE is only seeking EPA's approval of
the two new planned panels and has provided documentation to address
the two new panels within the context of the 19-panel design. DOE would
have to submit a separate request for approval of any additional panels
beyond panels 11 and 12.

II. Request for Comments
The Agency is soliciting public comment on DOE's documentation of
its PCR to add two new waste panels--panels 11 and 12--at the WIPP
facility, and the demonstration of compliance with EPA's disposal
regulations. Additional background information related to the Agency's
review of DOE's application--including an electronic copy of the PCR
itself--is available in the public docket \6\ established for this
action and on the EPA WIPP website.\7\

---------------------------------------------------------------------------
The Agency will accept comment until the September 16, 2024. Upon
completion of EPA's evaluation of the PCR, the Agency will announce a
decision on the proposed two new panels along with a response to
comments document and related technical support documents.
