Major Reports

Major reports refer to documents prepared by independent engineering consultants hired by National Grid and submitted to the Massachusetts Department of Environmental Protection (MassDEP) in compliance with the requirements of state environmental cleanup regulations. Among the reports posted on this page:

The Phase I Initial Site Investigation and Tier Classification, which indicated the presence of MGP-related compounds at the Site.

The Phase II Comprehensive Site Assessment Report, which describes the history of the Site, the upland and marine investigations conducted by National Grid, the findings of risk characterizations, and the Conceptual Site Model.

The Phase III Remedial Action Plan (RAP), which describes the technologies considered and the selection of a cleanup plan for the Site.

The Phase IV Remedy Implementation Plan (RIP), which describes the cleanup at the Site.

In addition to these major reports, National Grid also conducted a series of short-term measures known as Immediate Response Actions (IRAs) or Release Abatement Measures (RAMs) to address Site condition. The plans, status reports, and completion reports for each of these IRAs and RAMs are also posted below:
