An Act amending the act of October 18, 1988 (P.L.756, No.108), known as the Hazardous Sites Cleanup Act, providing for spill response and residential environmental protection; and, in fund, further providing for Hazardous Sites Cleanup Fund.

SB 1157 amends Pennsylvania's Hazardous Sites Cleanup Act to require immediate action for hazardous substance spills in residential areas. The bill mandates that responsible parties (such as owners, operators, or transporters) must promptly contain, clean up, and remove discharges threatening public health, drinking water, or residential environments. It imposes strict liability on these parties without requiring proof of fault and authorizes the Department of Environmental Resources to issue cleanup directives. The law aims to ensure faster responses to spills endangering homes, water supplies, and residents, aligning with Pennsylvania's constitutional environmental protections.
