National Grid currently provides updates on a weekly and monthly basis for the Rhode Island Department of Environmental Management (RIDEM) concerning activities and developments related to the environmental remediation of the site.
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.
