Mandatory Shoreland Zoning​
The Mandatory Shoreland Zoning Act (MSZA) requires municipalities to adopt, administer, and enforce local ordinances that regulate land use activities in the shoreland zone.

Nonpoint Source Management Program
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 2016.  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.
