The Hazardous Sites Cleanup Act (HSCA) provides DEP with the funding and authority to conduct cleanup actions at sites where hazardous substances have been released. HSCA also provides DEP with enforcement authority to force the persons who are responsible for releases of hazardous substances to conduct cleanup actions or to repay public funds spent on a DEP-funded cleanup action. Under the provisions of HSCA, most HSCA sites involve bankrupt facility owners, abandoned facilities and inappropriate disposal of hazardous substances. As a general rule, HSCA sites do not include active facilities with financially viable owners.
