The article quotes Beyond Nuclear:
Kevin Kamps, radioactive waste specialist at Beyond Nuclear, a nonprofit group that has been one of the leaders in the fight against the site, said environmental groups have partnered with oil and gas companies and agricultural businesspeople — who are in opposition to the Holtec proposal — “because you can’t have economic activity in a radioactive dead zone.”
“Our major concern is that it could become de facto permanent surface storage,” Kamps told Inside Sources. “There is no guarantee that Yucca Mountain will ever open. So New Mexico could be stuck with this waste forever.”
Both Kamps and the governor said since there is no permanent site, over time it is likely the casks holding SNF will lose integrity and require repackaging.
