Final answer:
Refrigerant from MVACs must be reused after purification, following regulations that ensure the protection of human health and the environment.
Step-by-step explanation:
The regulation stipulates that refrigerant recovered from Motor Vehicle Air Conditioners (MVACs) and MVAC-like appliances at disposal facilities can be reused in MVACs and MVAC-like appliances after purification. Refrigerants must be properly recycled or reclaimed to ensure that they meet industry purity standards before they can be sold or distributed for reuse. The utmost emphasis is placed on ensuring that recycled refrigerants do not harm the environment or human health. Therefore, they cannot be reused without any restrictions, only approved by EPA in certain circumstances, nor can they be recycled in peripheral nations, repurposed into new electronics, or dumped into ocean repositories.
