Municipal SWPPP Inspection Program

A Stormwater Pollution Prevention Plan (SWPPP) is a site-specific document that details the risks associated with that site’s industrial activities which could contaminate stormwater leaving that property with pollution.  A SWPPP is a plan that provides each industrial facility with the behavioral and structural guidelines necessary to reduce contaminants from entering the storm drains, conveyances, local streams and rivers. 

The Municipal SWPPP Inspection Program is designed to assist Prince George’s County’s municipalities who own industrial facilities in meeting the mandates of the Maryland Department of Environment’s (MDE) permit entitled the “NPDES General Discharge Permit for Stormwater Discharges Associated with Industrial Activity”. All holders of the NPDES “Industrial Permit” are required to develop and implement SWPPPs. DoE compiles SWPPP implementation progress and reports annually to Maryland Department of the Environment.

DoE has developed SWPPPs for the 9 Municipality owned facilities in Prince George’s County. Through technical and inspection assistance, the Municipal SWPPP Inspection Program additionally supports municipal industrial facilities in reducing their environmental impact.  DoE compiles SWPPP implementation progress reports annually to send to MDE.
