Westinghouse - Bureau of Land & Waste Management

Consent Agreement and Site Assessment 

On February 26, 2019, DHEC executed Consent Agreement #19-02-HW with Westinghouse to formally address historical contamination and implement a protocol for communicating and responding to any contamination discovered in the future. The consent agreement requires Westinghouse to conduct a comprehensive site-wide environmental assessment (also known as a Remedial Investigation) to fully determine the extent of contamination at the site. Once the assessment has been completed, methods for cleanup will be evaluated and implemented.   

DHEC’s site assessment documents and reports will be provided on this webpage as they are made available.
