DEP provides services to control nonpoint source water (NPS) pollution to help protect or improve Maine's lakes, streams, rivers, and coastal waters. This report summarizes accomplishments of NPS Program activities in 2020.  This work is funded, in part, under Sections 319 and 604(b) of the Federal Clean Water Act (CWA) in partnership with the U.S. Environmental Protection Agency.


  • Ten NPS watershed projects funded in previous years were completed reducing pollutant loads to waters by 314 tons/year of sediment, 646 pounds/year of phosphorus, and 226 pounds/year of nitrogen.  The report includes an outcome summary for each project.
  • DEP issued 11 new grants ($918,175) using 2020 CWA Section 319 funds to help communities implement actions called for in their watershed management plans to restore impaired waters or protect waters threatened by NPS pollution.
  • DEP also issued three grants using CWA Sections 604(b) and 319 funds to develop watershed-based plans.
