Which organization is responsible for enforcing regulations related to refrigerants in the U.S.?

The Environmental Protection Agency (EPA) is the organization responsible for enforcing regulations related to refrigerants in the United States. The EPA's authority comes from various environmental laws, including the Clean Air Act, which mandates the management of substances that potentially deplete the ozone layer and contribute to global warming. The EPA oversees adherence to regulations concerning the manufacturing, marketing, and use of refrigerants, ensuring compliance with safety and environmental standards.

In contrast, other organizations mentioned have different focuses. The Occupational Safety and Health Administration (OSHA) is primarily concerned with workplace health and safety, while the Department of Energy (DOE) focuses on national energy policy and research but not specifically on refrigerant regulations. The Consumer Product Safety Commission (CPSC) deals with consumer product safety but does not have direct authority over refrigerants, which means they do not enforce regulations specific to those substances.
