New Hampshire Construction
Stormwater Inspections
New Hampshire is covered by EPA's federal Construction General Permit as the state has not assumed NPDES authority. EPA Region 1 administers the permit for construction activities disturbing one or more acres. Projects must also comply with New Hampshire's Alteration of Terrain program for sites disturbing 100,000 square feet or more, creating dual regulatory requirements.
