On March 20, 2017, Region 1 conducted a CAA 112r/EPCRA inspection at High Liner's facility in Portsmouth, NH as a follow-up to a small ammonia release at the facility in August 2016 that was not reported to the National Response Center. The facility manufactures and packages a variety of seafood product for distribution to grocery stores throughout the U.S. The facility contains a refrigeration system that uses anhydrous ammonia in a quantity above the RMP threshold. As a result of the inspection, Region 1 identified numerous areas of concern related to the failure to maintain a safe workplace and the lack of adherence to industry standards for the ammonia refrigeration system.
