This document responds to a joint Petition for Reconsideration (Petition) that was submitted on October 31, 2019, by the American Gas Association, the American Petroleum Institute, the American Public Gas Association, and the Interstate Natural Gas Association of America (the Associations). In the Petition, the Associations requested that PHMSA amend the final rule titled "Safety of Gas Transmission Pipelines: MAOP Reconfirmation, Expansion of Assessment Requirements, and Other Related Amendments" (Gas Transmission Final Rule) published in the Federal Register on October 1, 2019. In response to the Petition, PHMSA is amending the Gas Transmission Final Rule to address the requirements for recordkeeping and the applicability of maximum allowable operating pressure (MAOP) reconfirmation. The amendments are intended to clarify the regulatory requirements identified in the Petition without adversely affecting safety.
