In June 2016, EPA Administrator Gina McCarthy issued a final rule establishing new source performance standards for fugitive emissions of methane and other pollutants by the oil and natural gas industries. The rule took effect on August 2, 2016, and required regulated entities to conduct an initial monitoring survey to identify leaks by June 3, 2017. After publication, several industry groups (American Petroleum Institute, Texas Oil and Gas Association, and Independent Petroleum Association of America) filed administrative petitions seeking reconsideration under Clean Air Act section 307(d)(7)(B), arguing it was impracticable to raise certain objections during the notice and comment period. On April 18, 2017, new EPA Administrator Scott Pruitt announced EPA would convene reconsideration proceedings and issue a 90-day stay of certain compliance deadlines. On June 5, 2017—just two days after the June 3 deadline for initial emissions surveys—EPA published a notice staying the effectiveness of fugitive emissions requirements, pneumatic pump standards, and professional engineer certification requirements for 90 days pending reconsideration. EPA also announced its intention to extend the stay for two years. Six environmental groups filed an emergency motion challenging the stay as unlawful.
