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.

In August 2019, National Grid submitted a combined permit application package to the Coastal Resources Management Council, the Army Corps of Engineers, and RIDEM to implement the Site remedy.

In June 2018, National Grid submitted a Remedial Action Work Plan (RAWP) to RIDEM for the Site.

A Community Outreach Event was held on October 29, 2020 to disseminate information and solicit questions regarding implementation of the remedy. This event was conducted virtually consistent with Rhode Island Executive Order No. 20-46 which was issued by the Governor’s office in response to the COVID19 pandemic.

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.

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.
