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, in miscellaneous, providing for release testing and reimbursement.

HB 662 amends Pennsylvania's Hazardous Sites Cleanup Act to clarify definitions and add new requirements for site owners. It updates the definition of "department" to specify the Department of Environmental Protection and creates a new section requiring owners of identified contaminated sites to conduct annual release testing for hazardous substances. Owners must also reimburse the department as outlined in existing section 507. This bill directly affects property owners at sites containing hazardous substances above background levels, including federal Superfund sites. The changes take effect 60 days after enactment.
