In December 2016, PHMSA issued an interim final rule (IFR) titled: “Pipeline Safety: Underground Natural Gas Storage Facilities” (81 FR 91860). In the IFR, PHMSA established minimum federal safety standards for intrastate and interstate underground natural gas storage facilities under its regulatory authority at 49 U.S.C. 60101 and 60102 and as directed by section 12 of the “Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016.” On January 18, 2017, the American Gas Association, the American Petroleum Institute, the American Public Gas Association, and the Interstate Natural Gas Association of America (INGAA) jointly submitted a petition seeking reconsideration of certain provisions of the IFR. (INGAA has since withdrawn from the petition.)

Recognizing that the IFR set certain deadlines by which the operators of underground natural gas storage facilities must act but that would occur before PHMSA could adopt a final rule, PHMSA published a notice on June 20, 2017, in the Federal Register (82 FR 28224), announcing that (1) the agency would not issue enforcement citations to operators for non-compliance with certain provisions of the IFR for a period of one year after publication of the final rule, and (2) it intended to address the issues raised by the petitioners in the final rule. For these reasons, PHMSA is now providing the public with an additional opportunity to comment on the IFR and an opportunity to comment on the issues raised in the petition. PHMSA is therefore reopening the comment period for this IFR until November 20, 2017. All documents and comments related to this matter are available for review at in docket number PHMSA-2016-0016.
