"Should Virginia take regulatory authority over the mill, then it will need to implement regulations that are compatible with ours," said David McIntyre, a spokesman for the NRC. State regulations can exceed the NRC's, he said.
The working group wants to hear the NRC scientists' views about those two options, said group spokeswoman Maureen Matsen, McDonnell's top energy adviser.
"I think they will give the folks the information they need to make that choice, as opposed to making that choice," Matsen said.
The NRC's von Till said he and his colleagues will outline the regulations, the NRC's experience with other uranium mills and the roughly 2 1/2 years' worth of stringent environmental reviews a mill would face before it is licensed.
A mill would grind the ore and rock removed from the mine and use chemicals to separate ore from the rock. The end product is yellowcake, which is packed in drums and shipped to uranium enrichment facilities.
"I would just stress we would do a full environmental impact statement," von Till said. "We're neutral. We don't have a dog in the fight."
The other NRC scientists at the meeting will be Larry W. Camper, director of the division of waste management and environmental protection; and Duncan White, chief of the agreement states branch.
The NRC delegation will take questions from the audience. The working group expects to post the NRC presentation on its website before the meeting.
The working group, which is scheduled to present its findings in November to McDonnell, will not make a recommendation whether the ban should be lifted. Its next meeting is in late August in Virginia Beach.
