NSTAR owns and operates utility poles which carry transformers within the Industri-Plex Site in Woburn, MA. The Industri-Plex is on the United States Environmental Protection Agency (USEPA) National Priorities List (NPL). The site was once home to a manufacturer of chemicals and animal hide processing.Both the USEPA and Massachusetts Department of Environmental Protection (MADEP) regulate the Industri-Plex as a federal Superfund Site and a state Hazardous Waste Disposal Site, respectively. To prevent migration of contaminants, a geotextile covered by clean soil was installed on over 110-acres of the Site as part of response actions and prior to commercial development on the Site. Work Plans and Health and Safety Plans are required to complete any work or upgrade within the subsurface of the Site. SAK Environmental was engaged to complete a Work Plan and Health and Safety Plan to complete utility upgrades within the Site.
