The correct answer highlights that leaking commercial and industrial process refrigeration systems must be repaired when the leak rate exceeds 35% of the charge per year. This standard is set by the EPA to ensure the integrity of refrigerant systems and to minimize environmental impact.

The rationale behind this threshold is based on balancing the operational efficiency of refrigeration systems with environmental concerns. A leak rate above this percentage indicates a significant loss of refrigerant, which can contribute to ozone depletion and global warming. Timely repairs help to prevent such excessive losses, promoting both regulatory compliance and protection of the environment.

Understanding these regulations is crucial for technicians working with refrigeration systems as it not only reinforces adherence to legal standards but also emphasizes the importance of sustainability in industrial practices.
