Hudson Technologies, Inc. (NASDAQ: HDSN), reports that the Environmental Protection Agency (EPA) has issued "No Action Assurance" letters to importers and producers of Hydrochlorofluorocarbon-22 (HCFC-22) that reduces the amount of HCFC-22 that can be manufactured and/or imported in 2012 by approximately 45% from the amount allowed to be produced and/or imported in 2011.

On January 4, the EPA published a Proposed Rule (the "Proposed Rule") that proposes to decrease annual HCFC-22 consumption allocations relative to the EPA's December 2009 final rule (the "2009 Final Rule") by a range of between 11 and 47 percent for calendar years 2012, 2013 and 2014. The Proposed Rule is not final and the EPA will be taking comment before issuing a final rule. Until the issuance of a final rule governing 2012 HCFC-22 allowances, the EPA's No Action Assurance limits the production and/or importation of HCFC-22 in 2012 to an amount equal to the maximum reductions proposed by the EPA in the Proposed Rule, representing approximately a 45% reduction from what was allowed to be produced and/or imported in 2011.
