Protected Natural Resources
Protected natural resources are coastal sand dune systems, coastal wetlands, significant wildlife habitat, fragile mountain areas, freshwater wetlands, great ponds and rivers, streams or brooks. See 38 MRSA 480-B for statutory definitions.
The purpose section of the Natural Resources Protection Act (NRPA) provides, in part, that: "The Legislature finds and declares that the State's rivers and streams, great ponds, fragile mountain areas, freshwater wetlands, significant wildlife habitat, coastal wetlands and coastal sand dune systems are resources of state significance. These resources have great scenic beauty and unique characteristics, unsurpassed recreational, cultural, historical and environmental value of present and future benefit to the citizens of the State and that uses are causing the rapid degradation and, in some cases, the destruction of these critical resources, producing significant adverse economic and environmental impacts and threatening the health, safety and general welfare of the citizens of the State."
The law is focused on "protected natural resources". A permit is required when an "activity" will be:
- Located in, on or over any protected natural resource, or
- Located adjacent to (A) a coastal wetland, great pond, river, stream or brook or significant wildlife habitat contained within a freshwater wetland, or (B) certain freshwater wetlands.
An "activity" is (A) dredging, bulldozing, removing or displacing soil, sand, vegetation or other materials; (B) draining or otherwise dewatering; (C) filling, including adding sand or other material to a sand dune; or (D) any construction, repair or alteration of any permanent structure.
Certain exemptions apply. A pre-application meeting is required for some projects, and is available on request for others. The NRPA is administered by the DEP in organized areas.

National Wetland Inventory Maps
Important Disclaimer: National Wetland Inventory (NWI) maps are produced by the U.S. Fish and Wildlife Service from interpretation of aerial photographs. They provide approximate information on the types, extent, and locations of wetland resources and are used for a variety of purposes. The accuracy of the NWI wetland information, especially wetland sizes and locations, can be a factor of the time of year when photographs were taken, the density of tree canopies, and other obstacles to photo-interpretation. They therefore should not be used as the sole source of information when accurate wetland information is critical. NWI maps do not substitute for site specific field investigations and wetland boundary delineations required by the Department pursuant to the Natural Resources Protection Act (38 M.R.S.A. §§480-A et seq.) and the Maine Wetland Protection Rules (Chapter 310).
