EPA Sets Final Rules on Uses of HCFCs

The U.S. Environmental Protection Agency on Dec. 11 announced two final rules that will further cut ozone-depleting pollutants, protecting the Earth’s ozone layer and reducing harmful greenhouse gases. The rules reduce the availability and use of hydrochlorofluorocarbons (HCFCs), which are primarily used as refrigerants and harm the ozone layer. A diminished ozone layer allows more radiation to reach Earth’s surface, leading to skin cancer, cataracts, and weakened immune systems.

The first rule prohibits the use of specific HCFCs to manufacture new air-conditioning and refrigeration equipment beginning in 2010, while allowing limited HCFC use to service existing equipment. The second rule prohibits the sale, distribution, and import of air-conditioning and refrigeration appliances and their components containing certain HCFCs that are manufactured or imported after Jan. 1, 2010. The rulemakings protect the ozone layer by decreasing the availability of these compounds as well as the demand for newly produced equipment containing HCFCs.

These rules advance U.S. compliance under the Clean Air Act and the Montreal Protocol on Substances that Deplete the Ozone Layer.
