Hope St., Room 949 Los Angeles, CA 90012 CPF 5-2024-018-WL Dear Mr. Cahill: On May 9, 2022, a representative of the California Public Utilities Commission on behalf of the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.), virtually inspected your operations and maintenance (O&M) manuals for the Los Angeles Department of Power and Water (LADWP) Harbor Generating Station gas transmission pipeline located in Long Beach, California. As a result of the inspection, it is alleged that you have committed probable violations of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected and the probable violations are: 1. 49 U.S.C. § 60108. Inspection and maintenance (a) . . . (2) If the Secretary or a State authority responsible for enforcing standards prescribed under this chapter decides that a plan required under paragraph (1) of this subsection is inadequate for safe operation, the Secretary or authority shall require the person to revise the plan. . . . In deciding on the adequacy of a plan, the Secretary or authority shall consider— (A) . . . (D) the extent to which the plan will contribute to— (i) public safety; (ii) eliminating hazardous leaks and minimizing releases of natural gas from pipeline facilities; … The LADWP's O&M Manual does not identify processes or procedures for minimizing releases of natural gas from pipeline facilities as required by 49 U.S.C. § 60108(a)(2)(D). Specifically, LADWP’s O&M Manual §6.2.4 mentions leak prone segments and states that cast iron and vintage plastic do not exist in their pipeline system. However, the O&M Manual does not discuss any programs or processes to monitor for and identify pipe segments that may be leak- prone nor provides any thresholds or criteria for determining whether a pipeline segment is leak- prone. 2. 49 U.S.C. § 60108. Inspection and maintenance (a) . . . (2) If the Secretary or a State authority responsible for enforcing standards prescribed under this chapter decides that a plan required under paragraph (1) of this subsection is inadequate for safe operation, the Secretary or authority shall require the person to revise the plan. . . . In deciding on the adequacy of a plan, the Secretary or authority shall consider— (A) . . . (E) the extent to which the plan addresses the replacement or remediation of pipelines that are known to leak based on the material (including cast iron, unprotected steel, wrought iron, and historic plastics with known issues), design, or past operating and maintenance history of the pipeline. The LADWP's O&M Manual does not address the replacement or remediation of pipelines that are known to leak based on the material (including cast iron, unprotected steel, wrought iron, and historic plastics with known issues), design, or past operating and maintenance history of the pipeline as required by 49 U.S.C. § 60108(a)(2)(E). Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed $266,015 per violation per day the violation persists, up to a maximum of $2,660,135 for a related series of violations.
