Natural Resources Protection Act (NRPA): separate DEP permit for projects affecting wetlands, significant wildlife habitat, or other protected natural resources.

Land Use Planning Commission (LUPC): governs ~10.5 million acres of Unorganized Territory (UT) in northern/remote ME (much of Aroostook, Piscataquis, Somerset, Penobscot, Washington, Franklin, Oxford, Hancock counties). DACF Permit: required for solar ≥5 acres on High-Value Agricultural Land (HVAL) — new, eff. April 20, 2025. Aroostook and Washington counties (far NE): outside ISO-NE footprint; served by Versant Power (Emera). Central ME Power (Avangrid) and Versant Power are Maine's two investor-owned utilities.
