GM2 provides ongoing environmental compliance support for the Airport’s NPDES Multi-Sector General Permit (MSGP). Tasks include conducting quarterly visual assessments of stormwater outfalls, completing inspections of the Airport’s facilities to monitor compliance with the Airport’s Stormwater Pollution Prevention Plan (SWPPP), recommending corrective actions to facilitate permit compliance, and preparing the MSGP Annual Report for submittal to the Environmental Protection Agency (EPA). GM2 recently updated the Airport’s MSGP SWPPP in accordance with the 2021 MSGP and prepared the Airport’s Notice of Intent for coverage under the new permit.



GM2 provided environmental permitting support for the removal of trees that are obstructions to the protected airspace around the Airport. Tasks included wetland delineation and preparation of the NHDES Wetlands Permit and Shoreland Permit applications. Since the project involved tree clearing within locally designated prime wetlands, coordination with the local conservation commissions was required and the project was presented at several commission meetings. Coordination with NHDES and the US Army Corps of Engineers was important to this project since mitigation was required for the wetland impacts.
