EP supports several Massachusetts communities with their Good Housekeeping and Pollution Prevention tasks (MCM-6) of the MS4 permit. These include quarterly inspections of municipal facilities where a Stormwater Pollution Prevention Plan (SWPPP) has been developed. A SWPPP is required at any facility where potential pollutants may be exposed to stormwater and discharged to local waterways.
Each year, at least one quarterly visit is conducted during a rain event, to observe the site conditions with active discharges. Recommendations for improvements and assisting the community with any future design considerations are provided by EP based off conditions found at each facility. Improvements may include site regrading, maintenance of structures or BMPs, as well as improved storage of materials.
