On September 29, 2020, EPA issued an administrative order on consent (AOC) to Tri-Town Arena Management LLC (Respondent) in Hooksett, New Hampshire, requiring it to comply with the Clean Air Act's General Duty Clause. Respondent operates a two-rink skating facility that uses anhydrous ammonia in its refrigeration system. Previously, there was a malfunction at the facility leading to the discharge of up to 100 pounds of ammonia, which required an immediate response from the Hooksett Fire Department. The AOC requires Respondent to complete a Process Hazard Review for the facility and submit it to EPA. The Respondent must also certify that it has submitted any missing chemical inventory form (Tier II form) required under Section 312 of EPCRA.
