The EPA finalized the Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources on June 3, 2016 (81 FR 35824). Several petitions were received in response to the final rule. The petitions have raised at least one objection to the fugitive emissions, pneumatic pump and professional engineer certification requirements included in the final rule that arose after the comment period or was impracticable to raise during the comment period and that is of central relevance to the rule. In this action, the EPA intends to issue a 90-day stay of the fugitive emissions, pneumatic pumps and professional engineer certification requirements. Sources will not need to comply with these requirements while the partial stay is in effect. The pneumatic pump and professional engineer certification requirements are already in effect, and the compliance date for the fugitive emissions requirements is June 3, 2017.
