What is the leak rate threshold starting in 2019 for R-22 that requires repair by the EPA?

The leak rate threshold for R-22 that necessitates repair, as established by the EPA starting in 2019, is indeed 20%. This rule aims to minimize the release of ozone-depleting substances into the atmosphere. Under these regulations, equipment that uses R-22 is required to be repaired if the annual leak rate exceeds 20%.

The significance of this standard lies in its role in environmental protection. The EPA has emphasized the importance of reducing emissions from refrigerants that can contribute to ozone depletion and climate change, prompting the establishment of strict guidelines. By setting the leak threshold at 20%, the EPA encourages owners and operators of refrigeration and air conditioning systems to proactively address leaks rather than allowing them to continue unmonitored.

This framework not only reflects the importance of adhering to environmental standards, but it also highlights the responsibility of those working with refrigerants to take action in preventing their harmful effects, thus preserving the integrity of the ozone layer.
