By STEVE SZKOTAKRICHMOND, Va. (AP) â¿¿ 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. The report, the latest of many examining uranium mining, sampled business attitudes about the issue in surveys conducted in November and December. Its primary message: while many business leaders were aware of the uranium deposit, few had a clear understanding how the ore would be extracted and processed for use in nuclear power reactors. "The need for clear, unbiased and accessible information provided a common thread through all the studies included in this report," wrote the authors, ORI, a market research firm in Herndon. Of the business leaders surveyed, about 60 percent were aware of the 119-million-pound uranium deposit in Southside Virginia and the debate over whether a 1982 moratorium should be lifted. The business leaders, however, have a low to moderate trust in the information available on perhaps the most important environmental issue in the state. "Respondents reported that although they have concerns about uranium mining, those concerns would decrease if they were to learn more about the processes and protections that are associated with the mining of uranium," the report said. Virginia Uranium Inc., based in Chatham, has proposed extracting the ore, which it values at $7 billion. The company has cast the mining as an economic plus for a region that could use the hundreds of jobs and tax revenues the mine would create. It has also stressed energy independence, with more than 90 percent of the nation's uranium coming from foreign sources.
