(a) Each operator shall maintain at each LNG plant the plans and procedures required for that plant by this part. The plans and procedures must be available upon request for review and inspection by the Administrator or any State Agency that has submitted a current certification or agreement with respect to the plant under the pipeline safety laws (49 U.S.C. 60101 et seq.). In addition, each change to the plans or procedures must be available at the LNG plant for review and inspection within 20 days after the change is made. § 193.2011 Reporting.

SPLNG submitted to PHMSA a revised procedure that addressed the requirements of § 193.2011 and § 191.22, respectively. SPLNG’s Operational Regulatory Periodic Reporting and Operations Review of FERC Permitting Procedure-CORP-OPS-RGCMPL-ADMPRC- 001642 (Revision Date: 11/06/2020) was reviewed by PHMSA and determined to be adequate.

SPLNG did not have adequate procedures to address the requirements of § 193.2515 for investigation of failures. PHMSA reviewed SPLNG’s written plans and procedures and observed that SPLNG did not specify that they will investigate the cause of each explosion, fire, LNG spill, or leak, which results in death or injury requiring hospitalization or property damage exceeding $10,000. SPLNG submitted to PHMSA a revised procedure that addressed the requirements of § 193.2515.
