According to the Clean Air Act, how many years must records related to MVAC system services be maintained?

The Clean Air Act mandates that records related to Motor Vehicle Air Conditioning (MVAC) system services must be maintained for a period of three years. This requirement is in place to ensure adequate tracking of service history, which is crucial for compliance with environmental regulations, particularly those concerning the handling and management of refrigerants that could impact the ozone layer. Keeping records for three years allows for efficient monitoring of service practices, provides accountability for technicians, and helps in regulatory inspections. The retention period supports the overall goal of reducing emissions of ozone-depleting substances, ensuring that technicians have proper documentation available if needed for regulatory purposes.
