How long must owners and operators of regulated appliances normally containing 50 or more pounds of HCFC refrigerant keep records of leak inspections, initial leak verification, and follow-up verification tests?

Owners and operators of regulated appliances that normally contain 50 or more pounds of HCFC refrigerant are required to keep records of leak inspections, initial leak verification, and follow-up verification tests for the life of the appliance. This requirement is in place to ensure accountability and to facilitate maintenance practices that help prevent leaks, which can harm the environment and lead to regulatory violations. Keeping records for the life of the appliance allows for a comprehensive historical view of the appliance's performance and the effectiveness of any mitigation measures taken over time. This thorough documentation supports compliance with environmental laws and helps in making informed decisions regarding future repairs or replacements.
