Co-applicants, NSTAR Electric Company d/b/a Eversource Energy (“Eversource”) and the Massachusetts Department of Conservation (“DCR”), have filed an application for a Major Stormwater Management Permit for construction of the Sudbury-Hudson Transmission Reliability and Mass Central Rail Trail Project. The Project includes construction of a new 115-kV underground transmission line and a multi-use path within an existing inactive railroad right-of-way, which will require removal of the existing rails and ties; vegetation clearing; grading; installation of the underground transmission line, duct bank, and manholes; installing a 14-foot-wide gravel base; paving of the 10-foot-wide rail trail; installation of stormwater management features; and site restoration.
Along the 4.3‑mile length in Sudbury, the Project will disturb approximately 643,985 square feet (14.8 acres), including 221,410 square feet on slopes greater than 10 percent, within an approximate 2,367,103 square feet (54.4 acres) Project Locus (the MBTA right-of-way). The increase in impervious surface associated with the Project for the paved multi-use path is approximately 226,556 square feet.
