National Grid has developed this website to provide the public with information about an environmental remediation project in and adjacent to Gloucester’s Inner Harbor. The former Gloucester Manufactured Gas Plant site (“MGP Site” or “Site”) extends along portions of Harbor Loop and Rogers Street, and into Gloucester Inner Harbor. The Massachusetts Electric Company d/b/a National Grid (National Grid) is undertaking a cleanup of the MGP Site. To learn more, visit the About the Site section of this website.
