The Remedial Design/Remedial Action (RD/RA) work will continue to implement the remedy selected by USEPA, as outlined in the Record of Decision (ROD, September 2015) and Statement of Work (August 2011). Prior to this RD/RA work, the Settling Defendants initiated two Non Time-Critical Removal Actions (NTCRA) for Building Demolition (2011) and Groundwater (2016) which situated the site with temporary liner over the demolished building sites and the permanent Ex-Situ Groundwater Treatment facility in place.
The five Remedial Components of the RD/RA (Soils & Sediment, ISS, Holding Basin, Ex-Situ Groundwater, and Bedrock Groundwater) will each consist of its own design and construction timeline. Progress will be featured accordingly on each web page.
Site-wide monitoring will be performed and updated as part of the overall project.
USEPA issued an Authorization to Proceed on 31DEC19 for de maximis, inc. as the Project Coordinator and Supervising Contractor for the Remedial Design / Remedial Action of the Nuclear Metals, Inc. Superfund Site.
The US District Court of Massachusetts entered the Consent Decree for the NMI Superfund Site Remedial Design and Remedial Action on December 6, 2019, thus initiating the timeline for performance of the work.
