The EPA recently provided a community update on the Olin Chemical Superfund Site:
Community Update (January 2024)
Olin Chemical Superfund Site – Wilmington, Mass.
EPA held an open house for the site in November and finalized the Community Involvement Plan (CIP). The posters from the open house and the CIP are available on EPA’s website:
www.epa.gov/superfund/olin under the “Announcements and Key Topics” section.
Under EPA oversight, Olin continues to collect information to address groundwater data gaps. This data will help refine and improve the effectiveness of future groundwater remediation. Additional data collection will continue through the 1st quarter of 2024.
As part of the ongoing Treatability Study for Dense Aqueous Phase Liquid (DAPL) and highly contaminated groundwater, Olin is currently evaluating additional treatment technologies for ammonia and n-nitroso dimethylamine (NDMA).
The results of this focused evaluation will be provided to EPA in April 2024.
A Consent Decree for the site was finalized in September 2023. Under the agreement, Olin will perform the cleanup. The first set of workplans were submitted in January 2024.
In December 2022, a real estate developer named Wilmington Woburn Industrial, LLC (WWI) requested that EPA consider entering into an agreement called a “Prospective Purchaser Agreement” or “PPA.” EPA is currently considering WWI’s request. Whether or not EPA enters into a PPA with WWI, and whether or not WWI ultimately purchases the Olin property, Olin remains responsible under the Consent Decree for performing the cleanup.
