A permit to renew the operating permit for the Waste Isolation Pilot Plant will be the subject of a hybrid public meeting in late September, hosted by the New Mexico Environment Department.
The facility – called WIPP – is the nation’s only storage site for defense-related nuclear waste, located in a salt bed 26 miles outside Carlsbad.
The meeting, which will be available remotely on WebEx or in-person in both Santa Fe and Carlsbad, will occur on Friday, Sept. 22, from 5 p.m. to 7 p.m.
Public comment on renewing the permit will remain open until the Sept. 22 meeting. The New Mexico Environment Department plans to issue a final permit in October, which would go into effect in November, according to a news release.
NMED shares regulatory responsibility with the U.S. Environmental Protection Agency. Only the EPA can oversee radiological portions of the site, however NMED inspects, oversees and addresses clean up at WIPP in the case of spills.
NMED published Tuesday a final proposed permit, a process that has taken years to resolve. The current permit expired in December 2020, and called for a closure of the plant in 2024. In the latest version of the renewal, the new permit is valid for 10 years from enactment.
WIPP contractors and NMED signed a settlement agreement, adding new provisions to the 1,200-page draft permit. One change included a permit revocation clause, if Congress increases the disposal limit, or allows for other types of waste at WIPP. The current maximum is 6.2 million cubic feet of waste.
WIPP contractors will also need to provide additional documentation, such as the U.S. Department of Energy’s progress on finding another site to store transuranic waste – meaning waste that’s heavier than uranium, often plutonium. WIPP will also be required to issue a report when the integrity of shipping containers are compromised.
WIPP is also required to develop a “community relations plan,” including three public meetings per year with at least 30 days of public notice.
While the permit does not establish a date of closure, it notes that the start of closure is when the site fills the facility to its capacity limit of 6.2 million cubic feet.
“The Permittees also assume closure will take 10 years,” the permit said, adding that the time frame could “be extended or shortened.”
Post-closure care of the site would extend another three decades.
