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it has undertaken the rulemaking because it believes current OSHA emergency response and preparedness standards are outdated and incomplete.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).

Growing GREEN. HOW NATURALS ARE GAINING A SHARE OF NEW MARKETS

Hydrofluorocarbons occupy a market space that is very large and diverse ranging from residential through all types of commercial to industrial. While HFCs appear to be a good choice from a perceived safety benefit, they are still pollutants and increasingly regulated chemicals. Regulatory requirements are forcing HFC users to make a switch to lower global warming potential systems, and it is impacting different markets in different ways.

THE LOCATION LANDSCAPE

The cost of real estate, an available workforce and proximity to transportation dictate where businesses build industrial refrigeration facilities, and those factors are more important than ever in recent years. As rising demand spurs cold chain growth, clear winner (and loser) locations are emerging from the patchwork of regional U.S. regulatory and business environments. Increasingly, those environments are taking center stage in decisions to build a facility or what refrigerant to use.
