National Grid
Rensselaer County, New York
To address reliability and electrical service concerns, National Grid designed and constructed a 230/115 kilovolt (kV) electrical substation and transmission line spur in Rensselaer County, NY. As the lead environmental permitting consultant for the project, EDR conducted state and federal wetland delineation and permitting, a Visual Impact Assessment, New York State Historic Preservation Office (SHPO) consultation, prepared a Part 102 report, and coordinated State Environmental Quality Review Act (SEQRA) compliance. In addition, EDR’s civil engineering team prepared preliminary grading plans, a stormwater management plan, planting plans, wetland mitigation plans, and a Stormwater Pollution Prevention Plan (SWPPP) for the project. Stormwater management features at the site include culverts, vegetated filter strips, vegetated swales, a wet pond and a pocket wetland. During construction of the project, EDR staff conducted weekly SWPPP inspections to ensure compliance with permitting conditions. Erosion and sediment control practices used at the site during construction included temporary polyurethane foam and permanent stone check dams, rolled erosion control fabric, silt fence, and soil stock piling.
