From the 1880’s through about the 1970’s, a manufactured gas plant (MGP) and electric generation facility operated at the end of Merry and Tidewater streets in Pawtucket, Rhode Island.

National Grid sent an abutter and mailing list notification to the Tidewater mailing list about the beginning of LDI work.

On April 19, 2018 RIDEM released a Remedial Decision Letter for the Former Tidewater Facility. This letter formally identifies the preferred remedial alternative and authorizes the development of a Remedial Action Work Plan (RAWP) in order to achieve the objectives of the environmental clean-up.

As part of facility upgrades, National Grid intends to complete certain reconstruction activities associated with the electrical substation on the site. While the soil data collected in the area of planned excavation suggest the potential for air quality impacts associated with this work is relatively low, National Grid will monitor air quality during these activities to confirm there are no air quality impacts.
