Erosion & Sedimentation Control - This program requires basic controls and site stabilization when a project involves filling, displacing, or exposing earthen material. No permit is required. The law sets a minimum across-the-board standard that helps prevent harm to surface waters.
Mining - This program regulates larger gravel pits, quarries, and clay and topsoil mining operations. For metallic mineral mining, see Site Location of Development.
Natural Resources Protection Act (NRPA) - This program regulates activities in, on, over or adjacent to natural resources such as lakes, wetlands, streams/rivers, fragile mountain areas, and sand dune systems. The program uses permit by rule (PBR) for certain classes of activity. Standards to be met focus on the possible impacts to the resources and to existing uses.
Shoreland Zoning - This program is primarily administered through municipalities, and involves the regulation of activities in the shoreland zone.
Site Location of Development - This program regulates developments that may have a substantial impact on the environment, as provided in law. Examples: large subdivisions, structures, 20 acre plus developments, and metallic mineral mining operations. Standards address a range of potential environmental impacts.
Stormwater - The Stormwater Program works toward protecting and restoring surface and groundwater impacted by stormwater flows. The Maine Stormwater Program includes the regulation of stormwater under three core laws: The Site Location of Development law (Site Law), Stormwater Management Law, and Waste Discharge Law (MEPDES). Aspects of stormwater are also addressed under industry specific laws such as the borrow pit and solid waste laws, and the rules administered by the Land Use Regulation Commission.
Watershed Management - Watershed management focuses on land use activities throughout a watershed with the goal of preventing polluted runoff from reaching surface water.
