EPA to reconsider portions of oil & gas NSPS. The U.S Environmental Protection Agency (EPA) will reconsider portions of its New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants for the oil and gas sector, finalized in August 2012. The Oil & Gas NSPS is currently being challenged by both industry and environmental groups in the D.C. Circuit. EPA asked the court to hold those cases in abeyance while it reconsiders portions of the rule. The agency anticipated issuing a proposed rulemaking for the NSPS by March 29, 2013 with a final rule by July 31, 2013. The provision requiring hydraulically fractured wells to flare VOC and methane emissions and then institute reduced emission completions (a/k/a "green completions") is not being challenged in the litigation and is not expected to be reconsidered by EPA.
