EPA Allocates 30 Tons of CFCs for Inhalers In 2010, Proposes Refrigerant Alternatives

摘要

The Environmental Protection Agency will allocate 30 metric tons of chlorofluorocarbons (CFCs) for metered dose inhaler production in 2010, less than what manufacturers had requested, according to a final rule published in the Federal Register May 10 (75 Fed. Reg. 25,780).rnIn a separate rulemaking, EPA also will propose listing isobutane, propane, HCR-188C, and HCR-188C1 as acceptable substitutes for CFC-12 and hydrochlorofluo-rocarbon (HCFC)-22, which are commonly used as refrigerants.
