Work on the AIM Act Continues
The U.S. Environmental Protection Agency continues to move forward with regulations under the American Innovation and Manufacturing (AIM) Act, which will restrict the use of hydrofluorocarbons. The agency is currently working on Subsection (h), which focuses on managing hydrofluorocarbons (HFCs) and substitutes. Tristam Coffin, co-founder of Effecterra and president of sustainability, policy, and technical services, said the EPA doesn't have a statutory date for finalizing the Subsection.

Emergency Release Reporting Best Practices Ensure Compliance
There are multiple regulatory requirements surrounding the use of ammonia in industrial refrigeration applications, including emergency release reporting requirements. Under the requirements, accidental releases must be promptly reported and managed, but it is important for users to avoid both under and over reporting. “According to EPA regulations, a facility must report any leak that exceeds the chemical’s reportable quantity (RQ)—100 pounds for anhydrous ammonia—immediately upon becoming aware of the leak,” said Bent Wiencke, principle at Chill-On LLC. “The EPA has established through precedent that ‘immediately’ means ‘within 15 minutes.'"

OSHA Proposes Expansion to Emergency Response Requirements
In February 2024, the U.S. Occupational Safety and Health Administration (OSHA) proposed new rule that would expand the reach of its emergency response standard. OSHA stated it has undertaken the rulemaking because it believes current OSHA emergency response and preparedness standards are outdated and incomplete. According to OSHA, current regulations do not address the full range of hazards facing emergency responders, lag behind changes in protective equipment performance and industry practices, conflict with industry consensus standards and are not aligned with many current emergency response guidelines provided by other U.S. federal agencies (e.g., Department of Homeland Security/Federal Emergency Management Agency).

Lesson Learned: Bad Decommissioning Mistake
I am sure that many of us have seen ammonia refrigeration systems that have operated for several decades, with equipment and system components functioning well past recommended operating life. This is a credit to manufacturers, installers, service technicians, and operators. Aging equipment and piping at some point will eventually require replacement. Or the system or portion of it may be decommissioned due to a business discussion. Due to various conditions, it may become necessary to decommission a system or portions of it, which is defined in ANSI/ IIAR 8- 2020 – Decommissioning of Closed-Circuit Ammonia Refrigeration Systems as: “The permanent deactivation of a closed-circuit refrigeration system.”
