Best Management Practices

MWRA is required to develop a Best Management Practices (BMP) plan to mitigate pollution at Deer Island Treatment Plant as well as at 11 other MWRA facilities (Combined Sewer Overflow Treatment Facilities, Headworks Facilities and the Sludge-to-Fertilizer Plant). The BMP plans, and any proposed changes or changes in facility operation that increase the potential for ancillary activities (materials storage areas, site runoff, accidental spillage, etc.) to result in receiving water impacts, are available to the public.

The BMP plans are maintained at each of the following facilities:

  • Deer Island Treatment Plant
  • Nut Island Headworks
  • Ward Street Headworks
  • Columbus Park Headworks
  • Chelsea Creek Headworks
  • Cottage Farm Combined Sewer Overflow (CSO) facility
  • Prison Point CSO facility
  • Somerville Marginal CSO facility
  • Constitution Beach CSO facility
  • Fox Point CSO facility
  • Commercial Point CSO facility
  • Sludge-to-Fertilizer Plant at Fore River

MWRA will also notify the EPA and MADEP within 60 days of any change in facility operation that materially increases the potential for ancillary activities to result in a release of hazardous or toxic pollutants.
