EPA is adjusting the allowance system controlling U.S. consumption and production of hydrochlorofluorocarbons (HCFCs) as a result of a 2010 Court decision vacating a portion of the 2009 final rule titled "Protection of Stratospheric Ozone: Adjustments to the Allowance System for Controlling HCFC Production, Import, and Export." 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. On August 5, 2011, EPA published an interim final rule allocating allowances for 2011. Today's action relieves the regulatory ban on production and consumption of these two chemicals following the Court's vacatur by establishing company-by- company HCFC-22 and HCFC-142b baselines and allocating production and consumption allowances for 2012-2014.
