As a result of the inspection, PHMSA has identified an apparent inadequacy found within Gulf South’s plans or procedures. The item inspected and the inadequacy is 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. Gulf South’s written procedures for conducting operations and maintenance activities were inadequate to ensure safe operation of a pipeline facility. Specifically, Gulf South failed to provide adequate procedures that describe the process for converting maximum and minimum pressure at the casing seat to a maximum and minimum wellhead pressure pursuant to API RP 1170, Section 9.1 (Section 9.1). Section 9.1 states in part that “[m]aximum storage operating pressures shall be established by the operator. The operator shall then convert the maximum and minimum pressure at the casing seat to a maximum and minimum wellhead pressure if the wellhead is the monitoring point of record.” During the inspection, PHMSA reviewed Gulf South’s procedure 1170-9-1 Operating Limits, effective 05/01/2024, which Gulf South uses for establishing the maximum storage operating pressure and found that the procedures were inadequate. The provided procedures did not describe the specific process used by Gulf South to determine the maximum pressure of the cavern. PHMSA also reviewed the procedures for converting the maximum and minimum pressure at the casing seat to a maximum and minimum wellhead pressure. The procedures were inadequate and did not describe the process used to convert these pressures. Therefore, Gulf South’s written procedures required by § 192.12(c) were inadequate. Gulf South must revise its procedures to address the deficiency outlined above. Response to this Notice This Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206.
