While anhydrous ammonia has many environmental and operational benefits, it is also an extremely hazardous substance that, if accidentally released, presents a significant health hazard because it is corrosive to the skin, eyes, and lungs. Ammonia is also flammable at certain concentrations in air.
The Environmental Protection Agency (EPA) would like to work with facilities that have ammonia refrigeration systems to improve their safety, protect workers and the public from
exposure to toxic gas, and avoid product losses.
Notice of Compliance Assurance and Enforcement Initiative
EPA is providing advance notice of an upcoming enforcement initiative so that you can take steps now to avoid a penalty before the initiative begins. The Initiative will focus on AMMONIA REFRIGERATION FACILITIES using LESS THAN 10,000 pounds to enhance their compliance with the General Duty Clause of Section 112(r) of the Clean Air Act (“CAA”), 42 U.S.C. §(r)(1), and with Section 312 of the Emergency Planning and Community Right-to- Know Act (EPCRA), 42 U.S.C. § 11022.
Failure to comply with these requirements puts the public at risk of exposure to anhydrous ammonia.
The goal of Section 112(r) of the Clean Air Act, 42 U.S.C. § 7412(r), is to reduce the risk of chemical accidents. Owners and operators of stationary sources producing, processing, handling, or storing extremely hazardous substances (EHS), including anhydrous ammonia, must:
