American Petroleum Institute v. EPA

The D.C. Circuit severed and held in abeyance challenges by industry petitioners to two aspects of EPA's emissions standards and guidelines for the oil and gas sector as to which administrative reconsideration was sought: (1) Vent gas net heating value (NHV) monitoring and alternate sampling demonstration requirements for flares and enclosed combustion devices; and (2) temporary flaring provisions for associated gas in certain situations. The main challenge to the regulation is at Texas v. EPA (No. 24-1054).
