An Act amending the act of October 18, 1988 (P.L.756, No.108), known as the Hazardous Sites Cleanup Act, in preliminary provisions, further providing for definitions and providing for disaster emergency declaration and for testing requirement, duty to report and public access; in powers and duties, further providing for powers and duties of department; and, in liability and settlement procedures, further providing for responsible person.

HB 574 amends Pennsylvania's Hazardous Sites Cleanup Act to update definitions and establish emergency water protections. It specifically adds PFAS chemicals (like PFOA and PFOS) to the definition of "hazardous substance" and creates a new designation for "special drinking water resource-impacted communities" when groundwater or surface water exceeds 10 parts per trillion of PFAS over a 12-month average or contains other pollutants threatening public water supplies. The bill grants the Governor authority to declare such communities and set immediate emergency water standards and cleanup requirements without waiting for full site remediation. This directly affects municipalities with contaminated water sources, particularly those dealing with PFAS contamination requiring urgent public health responses. The changes aim to streamline emergency actions for communities facing immediate drinking water risks from hazardous substances.
