Drainage, Stormwater & Our Natural Resources

The Town of Hampton hopes that by sharing resources we are able to collectively reduce stormwater pollution and improve water quality as a whole within our community, and throughout New Hampshire.

Changes to the Environmental Protection Agency (EPA) Construction General Permit (CGP)

Construction Projects that require coverage under this permit (Projects or activities that disturb one or more acres of land) need to take action to reduce the amount of materials, such as sediment that are picked up by stormwater and deposited into oceans, lakes, rivers, streams, wetlands and natural resources. If construction sites are not properly prepared and maintained the deposited materials can cause negative effects to the water quality of these waterbodies.

As required by the CGP the applicant will need to:

  • Develop a Stormwater Pollution Prevention Plan (SWPPP) and keep it up to date.
  • Complete and submit a Notice of Intent (NOI) to EPA.
  • Implement erosion and sediment controls and pollution prevention practices throughout the entire construction project. 
  • Conduct required inspections to verify compliance with permit. Inspections may only be conducted by a qualified person who is duly Certified as an Inspector by EPA. 
  • Conduct routine maintenance and take corrective action to fix problems with controls or discharges.
  • Complete and maintain documentation of all site inspections, dewatering inspections, and corrective actions.
  • Comply with turbidity monitoring requirements for dewatering discharges to sensitive waters (if applicable).
  • Comply with any State requirements in Part 9 of the permit.
