On April 16, 2025, EPA issued an Administrative Order on Consent (NOV/AOC) to Arctic Glacier addressing violations of Section 112(r) of the Clean Air Act at the company's cold storage warehouse in Sanford, Maine. The facility uses approximately 8,000 lbs. of ammonia its refrigeration system. An EPA inspection revealed multiple deviations from the CAA's General Duty Clause requirements to design and maintain a safe facility taking such steps as are necessary to prevent releases and minimize the consequences of a release should one occur. The AOC requires Arctic Glacier to (a) address the deficiencies identified during EPA's inspection, (b) certify compliance with the General Duty Clause requirements violated, and (c) evaluate compliance with ANSI/IIAR 9 at other ammonia refrigeration systems owned or operated by Arctic Glacier. The CAA Section 112(r) requirements are directly implemented by EPA in New England. Maine is not delegated to implement this program but will receive a copy of the AOC.
