New Mexico weighs changes to permit for nuclear waste dump

CARLBAD, N.M. (AP) — U.S. officials are pushing state regulators to clear the way for a new ventilation shaft to be built at the federal government’s nuclear waste repository in southern New Mexico, but watchdog groups say modifying the Waste Isolation Pilot Plant’s permit to allow for the construction could open the door to expansion.

The state Environment Department’s Hazardous Waste Bureau held a virtual hearing over the past week to gather comments on the proposed permit change. A final decision is anticipated in mid-October.

Ventilation has been an issue since 2014, when a radiation release contaminated parts of the underground facility and forced an expensive, nearly three-year closure, delayed the federal government’s cleanup program and prompted policy changes at national laboratories and defense-related sites across the U.S.

Officials with the U.S. Energy Department have said the new shaft is needed to repair a “crippled” ventilation system, the Carlsbad Current-Argus newspaper reported.

With more airflow, officials argue that more workers can be in the underground space working on mining and waste operations simultaneously.

“Air to an underground mine is like blood to body,” said Michael Woodward, counsel for the Energy Department and Nuclear Waste Partnership, the contractor that runs the facility. “Without sufficient airflow, and underground mine simply cannot operate. There must be sufficient air to allow multitasking in the underground.”

Woodward said at the hearing that the utility shaft was not intended to expand the repository. He said the amount of waste to be entombed there was established by Congress and only Congress could expand the plant’s mission.

Robert Kehrman, a retired geoscientist and consultant at the repository, testified about the need for the shaft to allow multiple operations to be done in tandem.
