AIKEN, S.C. (AP) - The contractor managing Savannah River Site's highly radioactive liquid waste is laying off 465 people.
The interim president of Savannah River Remediation informed employees in a memo Thursday. Stuart MacVean says affected workers' last day will be Sept. 27.
The contractor represents a team of companies that oversees the site's liquid waste, including clean-up efforts of underground tanks.
Its workforce will shrink to about 1,700 employees.
The director of South Carolina's environmental control agency calls the waste stored in the site's degrading tanks the state's single largest environmental threat. Catherine Templeton has warned the U.S. Energy Department the state will fully enforce its agreements on clean-up milestones she believes are threatened by federal budget proposals. They include $154 million in fines if a waste processing facility doesn't open in 2015.Copyright 2013 The Associated Press. All rights reserved.
