EPA is adjusting the allowance system controlling U.S. consumption and production of hydrochlorofluorocarbons (HCFCs) as a result of a recent court decision vacating a portion of the rule titled "Protection of Stratospheric Ozone: Adjustments to the Allowance System for Controlling HCFC Production, Import, and Export; Final Rule." EPA interprets the court's vacatur as applying to the part of the rule that establishes the company-by-company baselines and calendar-year allowances for HCFC-22 and HCFC-142b. This action relieves the regulatory ban on production and consumption of these two chemicals following the court's vacatur by establishing new company-by- company HCFC-22 and HCFC-142b baselines and allocating production and consumption allowances for 2011.
