Sheridan, Suite 1500 Oklahoma City, OK 73102 CPF 1-2021-069-NOA Dear Mr. Sailor: From June 14, 2021 to June 18, 2021, representatives of the Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected Enable Mississippi River Transmission, LLC’s (Enable) records and procedures for Enable’s underground storage construction activities in Saint Jacobs, Illinois. On the basis of the inspection, PHMSA has identified the apparent inadequacy found within Enable’s plans or procedures, as described below: 1. § 192.12 Underground natural gas storage facilities. (a) … (c) Procedural manuals. Each operator of a UNGSF must prepare and follow for each facility one or more manuals of written procedures for conducting operations, maintenance, and emergency preparedness and response activities under paragraphs (a) and (b) of this section. Each operator must keep records necessary to administer such procedures and review and update these manuals at intervals not exceeding 15 months, but at least once each calendar year. Each operator must keep the appropriate parts of these manuals accessible at locations where UNGSF work is being performed. Each operator must have written procedures in place before commencing operations or beginning an activity not yet implemented. CPF 1-2021-069-NOA Enable’s written procedures for conducting operations, maintenance, and emergency preparedness and response activities were inadequate to ensure safe operation of a pipeline facility. Specifically, Enable failed to have written procedures that specified compliance with applicable fire codes and regulations, as required by API RP 1171, Section 10.3.21 (Section 10.3.2) and incorporated by reference under § 192.12(b)(2),2 as required by § 192.12(c). During the inspection, PHMSA observed that fences or enclosures were placed at gas storage wells. However, Enable’s procedures failed to specify that fences or enclosures shall comply with applicable fire codes and regulations as required by Section 10.3.2. After the inspection, Enable confirmed to PHMSA over email that, at the time of the inspection, they had fences or enclosures at the St. Jacob gas storage wells but they did not have procedures in place to ensure they complied with applicable state and local fire codes. Therefore, Enable’s written procedures required by § 192.12(c) were inadequate. Enable must revise its procedures to address applicable fire codes and regulations for fences or enclosures in accordance with Section 10.3.2.

(1) … (2) Each UNGSF that uses a depleted hydrocarbon reservoir or an aquifer reservoir for natural gas storage and was constructed on or before July 18, 2017, must meet the provisions of API RP 1171 (incorporated by reference, see § 192.7), sections 8, 9, 10, and 11, and paragraph (c) of this section, by January 18, 2018, and must meet all provisions of paragraph (d) of this section by March 13, 2021. 12021069NOA_Notice of Amendment_12102021_(20-198144)_text Page 2 of 3 CPF 1-2021-069-NOA procedures are found inadequate as alleged in this Notice, you may be ordered to amend your plans or procedures to correct the inadequacies (49 C.F.R. § 190.206).
