EPA Launches Region 10 Initiative for Facilities Under 10,000 lbs of Ammonia

The Environmental Protection Agency has launched an initiative in the Pacific Northwest to improve the safety of smaller ammonia refrigeration facilities – focused on facilities with under 10,000 pounds of ammonia. The initiative, which is being carried out by EPA Region 10, was developed with input from EPA region 1 and the International Institute of All-Natural Refrigeration. It is aimed at improving compliance with the General Duty Clause of Section 112(r) of the Clean Air Act. Section 112(r) specifies that owners and operators of stationary sources producing, processing, handling, or storing extremely hazardous substances, including anhydrous ammonia, have the duty to reduce the risk of chemical accidents.

EPA Finalizes Third AIM Act Rule

The American Innovation and Manufacturing (AIM) Act, which was enacted on December 27, 2020, authorized the EPA to address hydrofluorocarbons (HFCs) in three areas: (1) Phasing down HFC production, (2) Facilitating the transition to next-generation technologies through sector-based restrictions and (3) Regulating to minimize HFC releases and maximizing reclamation efforts. The EPA has methodically executed on this mandate with the three rules addressing each of these areas. The third of these rules has just completed its public review period and has been finalized.
