Final answer:
The EPA requires reclaimed refrigerant to meet specific quality standards before it can be resold, safeguarding both human health and the environment.
Step-by-step explanation:
Under the Environmental Protection Agency's (EPA) regulations, reclaimed refrigerant must meet certain quality standards before it can be resold. These standards ensure the refrigerant is pure, safe, and environmentally acceptable for use. The EPA, responsible for air quality along with other environmental regulations, imposes strict requirements to safeguard public health and prevent environmental harm.
This is similar to the way EPA has set National Ambient Air Quality Standards for "criteria" air pollutants, ensuring they meet health-based or environmentally-based standards. Such regulations are part of a broader mission by the agency to regulate various aspects of the environment, which includes managing hazardous waste and protecting drinking water.
