What is the leak rate threshold for industrial process refrigeration according to EPA regulations?

The leak rate threshold for industrial process refrigeration according to EPA regulations is indeed 30% of the charge per year. This standard is established to ensure that businesses take necessary actions to minimize refrigerant loss, which contributes to ozone depletion and climate change. By setting this threshold, the EPA encourages proper maintenance and timely repairs of refrigeration systems, aiming to limit the environmental impact associated with refrigerant leaks.

If the system's leak rate exceeds this threshold, the facility is required to follow specific protocols for monitoring and repairing the leaks, demonstrating their commitment to environmental stewardship while complying with federal regulations.

Regulations are designed to hold larger and more complex systems—like those found in industrial settings—to strict standards, given their potential for significant emissions. Understanding this threshold is critical for those working in refrigeration and HVAC to ensure compliance and responsible management of refrigerants.
