The U.S. Environmental Protection Agency (EPA) has published a final rule that sets air pollution standards for natural gas hydraulic-fracturing operations. 77 Fed. Reg. 49,489 (8/16/12). In addition to addressing fracturing, the new standards cover other new and modified oil-and-gas operations, including centrifugal compressors, reciprocating compressors, pneumatic controllers, and storage vessels. The rule also includes national emissions standards for hazardous air pollutants for oil-and-gas production facilities and gas transmission and storage facilities. The rule does not require industry to use reduced emissions completion equipment to capture excess gas at fracturing wells until 2015. Until then, industry will have the option of reducing emissions by flaring off excess gas. The final rule is effective October 15, 2012.
