Over the last ten years, Pennsylvania has made steady progress in reducing the amount of hazardous waste generated, in cleaning up and redeveloping sites that are contaminated with hazardous waste, and in addressing other potential environmental impacts such as storage tanks, abandoned mines, and oil and gas drilling and production practices. However, more progress is needed to further reduce the environmental impacts of hazardous waste in the Commonwealth. From 2001 to 2011, the amount of hazardous waste generated annually in the Commonwealth has decreased by 23 percent. Pennsylvania's waste-related environmental challenges extend beyond the boundaries of the Resource Conservation and Recovery Act (RCRA) Subtitle C definition of hazardous waste and include wastes associated with recent oil and gas drilling and production activities, historic coal mining, and the management of coal combustion residuals.
