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 is planning on performing additional investigation activities at the Tidewater facility to assess soil gas quality at the Site. The work is anticipated to start in early July 2013 and take approximately 2 weeks to complete.

As part of on-going electric facility upgrades, National Grid is completing certain construction activities at our on-site substation. Earthwork began in late December 2012. The majority of excavation is complete. Minor excavation (associated with utility conduit within the substation) will be completed in October 2013. Extensive soil sampling was performed in the area to be excavated during this project. While the soil data collected in the area of planned excavation suggest the potential for air quality impacts associated with this work is very low, National Grid will monitor air quality during these activities to confirm, in accordance with the plans submitted to RIDEM.

The former Tidewater Manufactured Gas Plant (MGP) and Power Plant site (“site”) is an approximately 23-acre property located immediately to the east of Tidewater Street and Merry Street in Pawtucket, Rhode Island. It is bordered by the Seekonk River.
