Abstract
On July 16, 2024, the Environmental Protection Agency (EPA or the Agency) announced for public comment the availability of a Planned Change Request (PCR) recently submitted by the U.S. Department of Energy (DOE) to modify the Waste Isolation Pilot Plant (WIPP). The proposed change will involve adding two additional waste panels west of the current repository to replace lost disposal capacity resulting from the 2014 radiological incident and resulting ground control issues. A 60-day comment period was provided for the PCR that expired on September 16, 2024. A request for an extension to the comment period was received from several stakeholders, most recently at the Agency's informal public meetings held in New Mexico in late August. EPA is reopening the comment period to seek public input on both DOE's application and on what EPA should consider in its evaluation.

Planned Change Request for Waste Isolation Pilot Plant
Replacement Panels 11 and 12; Reopening of Public Comment Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability with request for public comment;
reopening of public comment period.
-----------------------------------------------------------------------
SUMMARY: On July 16, 2024, the Environmental Protection Agency (EPA or
the Agency) announced for public comment the availability of a Planned
Change Request (PCR) recently submitted by the U.S. Department of
Energy (DOE) to modify the Waste Isolation Pilot Plant (WIPP). The
proposed change will involve adding two additional waste panels west of
the current repository to replace lost disposal capacity resulting from
the 2014 radiological incident and resulting ground control issues. A
60-day comment period was provided for the PCR that expired on
September 16, 2024. A request for an extension to the comment period
was received from several stakeholders, most recently at the Agency's
informal public meetings held in New Mexico in late August. EPA is
reopening the comment period to seek public input on both DOE's
application and on what EPA should consider in its evaluation.
DATES: The public comment period for the notice published July 16, 2024
at 89 FR 57887, has reopened on October 22, 2024. It will remain open
until the Agency publishes a future notice in the Federal Register that
specifies the end of the public comment period.

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
[[Page 84349]]
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
A 60-day comment period provided for comments on the PCR ended on
September 16, 2024. During this comment period a request for an
extension to the comment period was received from several stakeholders,
most recently at the Agency's informal public meetings held in New
Mexico in late August.
The Agency is reopening the comment period and 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\

\7\ <a href="https://www.epa.gov/radiation/wipp-news#WIPP-PCR">https://www.epa.gov/radiation/wipp-news#WIPP-PCR</a>.
---------------------------------------------------------------------------
The Agency will continue to accept comment until it issues a future
Federal Register notice that specifies the end of the public comment
period. 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.
