Cal. PUC § 958.5

(a) Twice a year, or as determined by the commission, each gas corporation shall file with the division of the commission responsible for utility safety a gas transmission and storage safety report. The division of the commission responsible for utility safety shall review the reports to monitor each gas corporation’s storage and pipeline-related activities to assess whether the projects that have been identified as high risk are being carried out, and to track whether the gas corporation is spending its allocated funds on these storage and pipeline-related safety, reliability, and integrity activities for which they have received approval from the commission.

(b) The gas transmission and storage safety report shall include a thorough description and explanation of the strategic planning and decisionmaking approach used to determine and rank the gas storage projects, intrastate transmission line safety, integrity, and reliability, operation and maintenance activities, and inspections of its intrastate transmission lines. If there has been no change in the gas corporation’s approach for determining and ranking which projects and activities are prioritized since the previous gas transmission and storage safety report, the subsequent report may reference the immediately preceding report.

(c) If the division of the commission responsible for utility safety determines that there is a deficiency in a gas corporation’s prioritization or administration of the storage or pipeline capital projects or operation and maintenance activities, the division shall bring the problems to the commission’s immediate attention.
