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 County’s SWPPP Inspection Program is designed to assist County owned 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.” Through technical and inspection assistance, the County SWPPP Inspection Program supports county owned industrial property in reducing their environmental impact.

 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.

There are 9 County owned facilities included in the program:

• DoE’s Brown Station Road Landfill Facility
• DPW&T’s Brandywine Facility
• DPW&T’s Glendale Facility
• DPW&T’s Ritchie Service Facility
• DoE’s Materials Recycling Facility
• DoE’s Missouri Avenue Convenience Center
• OCS’s Central Vehicle Maintenance Facility
• DoE’s Sandy Hill Creative Disposal Project
• DoE’s Western Branch Composting Facility

Each facility maintains their current SWPPP on site and copies are held at DoE and MDE. Regulatory information is found on MDE's website.
