NPDES-MS4 - National Pollutant Discharge Elimination System - Municipal Separate Storm Sewer System
What is Stormwater?
Stormwater is water that runs off impervious surfaces such as rooftops, paved roads, driveways and parking lots. Stormwater carries sediment and surface pollutants such as petroleum products, litter/trash, phosphorus and nitrogen. Stormwater is washed down storm drains. The vast drain piping network carries the stormwater into one of the many brooks or ponds in the City where it ultimately ends up in the Sudbury River or the many outfall locations in the town.
Town of Ashland manages the Town's Municipal Separate Storm Sewer System (MS4). The Town is authorized to discharge stormwater through the Phase II National Pollutant Discharge Elimination System(NPDES) general permit for all small MS4s. The United states EPA (Environmental Protection Agency) oversees the NPDES Phase II pemritting program. In order to comply with the program, the Town must follow six Minimum Control measures, which are implemented through a series of Best Management Practices (BMPs).
