Nitto Denko Avecia, an oligonucleotide manufacturer based in Milford, will pay $858,889 to resolve alleged hazardous waste violations at two Fortune Boulevard campuses, federal records show. The agreement follows a 2023 hazardous waste compliance inspection that flagged problems with tank systems, air emissions, labeling and contingency planning.
Federal settlement and required fixes
The settlement is laid out in a Region 1 consent agreement that requires Nitto Denko Avecia to pay $858,889 and complete a slate of corrective actions at its 125 and 155 Fortune Blvd. facilities within specified deadlines. EPA says the alleged violations were identified during a compliance evaluation from September 19 to 21, 2023, and included suspected hazardous waste air emission failures, tank system design and installation deficiencies, missed inspections and labeling lapses. The agreement requires the company to implement a leak detection and repair program, inspect tanks daily, properly label hazardous waste units, revise its contingency plan and provide hazardous waste training, according to the consent agreement filed with U.S. EPA.
Local reaction and comment
Regional officials framed the agreement as a reminder to manufacturers about compliance, with Mark Sanborn saying the deal "serves as a reminder to manufacturers about their duties," as reported by the Worcester Business Journal. That report also notes company officials could not be reached for comment. The Business Journal published its coverage on June 10.
Who Nitto Denko Avecia is
Nitto Denko Avecia is a private biotechnology company focused on oligonucleotide production and lists two Milford campuses at 125 and 155 Fortune Boulevard, according to the company website. The firm has in recent years described capacity and regulatory milestones for its oligonucleotide manufacturing business on its site, which frames the Milford operations as part of a broader contract manufacturing platform, per Nitto Denko Avecia.
Case status and local impact
EPA’s administrative docket (Docket No. RCRA-01-2026-0014) shows the consent agreement was filed Feb. 5 and the case closed Feb. 12 with a disposition of "Payment Received," per the U.S. EPA administrative docket. The Worcester Business Journal reports the Milford operations employ roughly 400 people, underscoring the settlement’s local economic and regulatory significance. The docket lists the action as a CAFO and records the required payment and compliance milestones in the administrative record.
Legal note
The consent agreement resolves federal civil penalty claims but does not require Nitto Denko Avecia to admit wrongdoing; the company "neither admits nor denies" the factual allegations while agreeing to the settlement terms. The order also preserves EPA’s authority to pursue further action if warranted and requires proof of payment along with documentation that the company has met its compliance obligations, as detailed in the consent agreement on file with U.S. EPA.
