RICHMOND, Va. (AP) — A narrow majority of 652 business leaders from across Virginia opposes ending the state’s decades-old moratorium on uranium mining, but their concerns could by allayed if they learned more about how the radioactive ore is mined and what protections would be in place, a survey released Tuesday said.

The report was the final issued by Gov. Bob McDonnell’s Uranium Working Group, which in late November laid out the regulatory structure that would be required if Virginia allowed a mining company to tap uranium deposit in Pittsylvania County that is the largest in the U.S. The issue is expected to be fiercely debated in the General Assembly this session.
