EPA published the final rule, “Oil and Natural Gas Sector: New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants Reviews,” last week. The rule, which was finalized in April, and we blogged about here, sets the first air pollution standards for hydraulic fracturing operations. For hydraulic fracturing, the rule will require owners/operators to use reduced emissions completions, also known as RECs, and a completion combustion device to reduce VOC emissions beginning on January 1, 2015. Up until January 1, 2015 owners/operators may flare gas to reduce emissions. The new rule not only addresses hydraulic fracturing, it also includes performance standards for other modified oil and gas operations, such as centrifugal compressors, storage vessels, and pneumatic controllers. The final rule is effective on October 15, 2012.
