On May 12, 2016, U.S. EPA finalized amendments to the New Source Performance Standards (NSPS) for the oil and natural gas source category at 40 CFR Part 60, Subpart OOOO, and established new standards at 40 CFR Part 60, Subpart OOOOa. The final rule establishes standards for greenhouse gas emissions in the form of limitations on methane emissions, and requires additional sources not originally subject to Subpart OOOO to comply with with the VOC and methane limitations prescribed under the rule.
