DEP Oversight

The Bureau of Clean Water (BCW) is responsible for overseeing the implementation of monitoring, compliance and enforcement activities under Pennsylvania’s Clean Streams Law(opens in a new tab) (PDF) and the federal National Pollutant Discharge Elimination System (NPDES) program. The Clean Water Program in DEP’s six regional offices is largely responsible for implementing these activities, which include:

Of these activities, inspecting NPDES-permitted facilities constitutes the largest use of resources, as Pennsylvania has over 10,000 permitted wastewater facilities. Each year BCW develops a Compliance Monitoring Strategy(opens in a new tab) (PDF) (CMS) to identify objectives for completing inspections of NPDES-permitted facilities during a federal fiscal year. The CMS is transmitted to the U.S. Environmental Protection Agency(opens in a new tab).

DEP generally conducts over 4,000 NPDES inspections and completes over 500 NPDES enforcement actions annually. You can review NPDES inspection, violation, and enforcement actions by visiting the Wastewater Reports page.
