An Act amending the act of January 8, 1960 (1959 P.L.2119, No.787), known as the Air Pollution Control Act, further providing for powers and duties of the Department of Environmental Protection and for civil penalties.

HB 1187 amends Pennsylvania's Air Pollution Control Act to require major facilities (as defined in state code) to create and maintain municipal notification plans. These plans must alert nearby municipalities within 12 hours of air pollution incidents posing health risks, including communication methods, public safety measures, and annual updates. The bill also increases civil penalties for violations, raising daily fines to $37,500 after the fifth year of implementation based on factors like severity and environmental damage. This affects industrial facilities and their adjacent communities by mandating faster emergency communication and strengthening enforcement.
