[Docket No. PHMSA-2013-0255, Amdt. Nos. 192-134, 195-106]
PHMSA issued editorial and technical corrections clarifying the regulations in its April 8, 2022, final rule titled “Pipeline Safety: Requirement of Valve Installation and Minimum Rupture Detection Standards” for certain gas, hazardous liquid, and carbon dioxide pipelines. (See related article in the June 2022 edition of the “DOT Pipeline Compliance News”). These technical corrections are effective August 1, 2023, and are summarized as follows:
- Corrections in § 192.179(e) and (f) to clarify that rupture mitigation valve (RMV) installation exemptions apply to:
- 1a. Class 1 locations with a PIR of 150 feet or less, and
- 1b. Class 2 locations with a PIR of 150 feet or less
- Corrections in § 192.179(e) and (f) so that it is clear that all new pipelines, regardless of HCA status or class location, must install RMVs in accordance with § 192.179.
- Amending § 192.610(b) to make it clear that the provisions applied to transmission pipelines, as in § 192.610(a).
- Correcting omission of word “and” from § 192.634(b)(3).
- Moving operational requirement for manual operation of valves from § 192.634(c) into § 192.636(h), as originally intended. The requirements at § 192.634 are otherwise unchanged.
- Several clarifications related to § 195 (liquids pipelines).
- Vacating of all provisions of the final rule as they apply to gas (and liquid) gathering lines, as per the May 2023 decision by the U.S. Court of Appeals for the D.C. Circuit.
