Fifth Street Los Angeles, California 90013 CPF 1-2021-073-NOA Dear Mr. Drury: From October 20, 2020 to October, 23, 2020, California Geologic Energy Management Division (CalGEM), acting as an agent for the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected Southern California Gas Company’s (SCG) procedures for their Aliso Canyon, Honor Rancho, and Playa Del Rey Underground Natural Gas Storage Facilities (UNGSF) located in Los Angeles County, California and their La Goleta UNGSF located in Santa Barbara County, California. SCG submitted its amended procedures on January 27, 2022. My staff reviewed the amended procedures, and it appears that the inadequacies outlined in this Notice of Amendment have been corrected. This letter is to inform you no further action is necessary and this case is now closed. Thank you for your cooperation. Sincerely, Robert Burrough Director, Eastern Region Pipeline and Hazardous Materials Safety Administration 12021073NOA_Notice of Amendment_12162021_(20-197117)_text.pdf NOTICE OF AMENDMENT OVERNIGHT EXPRESS DELIVERY December 16, 2021 Mr. Scott Drury Chief Executive Officer Southern California Gas Company 555 W. Fifth Street Los Angeles, California 90013 CPF 1-2021-073-NOA Dear Mr. Drury: From October 20, 2020 to October, 23, 2020, California Geologic Energy Management Division (CalGEM), acting as an agent for the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected Southern California Gas Company’s (SCG) procedures for their Aliso Canyon, Honor Rancho, and Playa Del Rey Underground Natural Gas Storage Facilities (UNGSF) located in Los Angeles County, California and their La Goleta UNGSF located in Santa Barbara County, California. On the basis of the inspection, PHMSA has identified the apparent inadequacy found within SCG’s procedures, as described below: 1. § 192.12 Underground natural gas storage facilities. (a) … (d) Integrity management program— (1) … (4) Integrity management procedures and recordkeeping. Each UNGSF operator must establish and follow written procedures to carry out its integrity management program under API RP 1171 (incorporated by reference, see § 192.7), section 8 ("Risk Management for Gas Storage Operations"), and this paragraph (d). The operator must also maintain, for the useful life of the UNGSF, records that demonstrate compliance with the requirements of this paragraph (d). This includes records developed and used in support of any identification, calculation, amendment, modification, justification, deviation, and determination made, and any action taken to implement and evaluate any integrity management program element. CPF 1-2021-073-NOA SCG’s written procedures for carrying out its integrity management program under API RP 1171, Section 8 were inadequate to ensure safe operation of a pipeline facility. Specifically, SCG’s Storage Integrity Management Plan 2 (SIMP2) did not provide specific information to be collected and used to assess threat and hazard interactions in accordance with API RP 1171, Section 8.3.2 (Section 8.3.2).1 During the inspection, CalGEM reviewed SCG’s SIMP2 procedure. The SIMP2 procedure stated in part: SoCalGas has identified appropriate sources of information for the required data elements. The data sources are typically associated with design, construction, operational, or maintenance records in compliance with the Sempra’s Information Management Policy. The following databases are utilized to capture data: 3.2.1. WellView: A well data management system containing data related to planning, drilling, completion, abandonment, testing and workovers. 3.2.2. RigView: A rig and well project scheduling system for drilling, completions, workovers and testing. 3.2.3. OSI Soft PI: The repository for process information such as storage field injection and withdrawal rates, and well pressures. 3.2.4. Maximo: The maintenance management system for storage facilities. Inspection activities for the following well components are scheduled and recorded in Maximo: 3.2.4.1. Wellhead valve 3.2.4.2. Surface safety valve 3.2.4.3. Surface-controlled subsurface safety valve 3.2.5. SAP: Invoice management system. 3.2.6. Petrel: Geology software platform. SCG’s SIMP2 procedure identified appropriate sources of information under Section 8.3.2 but did not sufficiently specify what data and information would, at a minimum, be collected from these sources and used to assess threat and hazard interactions. Additionally, SCG’s SIMP2 procedure currently states that the data collected will be used to “determine susceptibility to threat and hazard-related events and to assess threat interaction.”2 Section 8.3.2 requires operators to use available information to determine susceptibility to threat and hazard-related events and assess threat and hazard interaction. SCG must amend its procedures to clarify that the data collected under Section 3 of the SIMP2 procedure will be used to assess threat and hazard interactions. 1 API RP 1171, Section 8.3.2 Data Sources The operator shall use available information such as performance data collected through the field history, operations and maintenance (O&M) activities, geotechnical data such as well logs, engineering data, and completion reports to determine susceptibility to threat and hazard-related events and to assess threat and hazard interaction. 2 SIMP2, 3. Data Collection, at 4 (on file with PHMSA). 12021073NOA_Notice of Amendment_12162021_(20-197117)_text Page 2 of 3 CPF 1-2021-073-NOA Therefore, SCG’s written procedures, required by § 192.12(d)(4), were inadequate. SCG must revise its procedures to more clearly specify what information will be collected and used to assess threat and hazard interaction in accordance with Section 8.3.2.
