Based on the inspection, PHMSA has identified apparent inadequacies found within DCP’s procedures as described below: 1. § 195.402 Procedural manual for operations, maintenance, and emergencies. (a) General. Each operator shall prepare and follow for each pipeline system a manual of written procedures for conducting normal operations and maintenance activities and handling abnormal operations and emergencies. § 195.444 Leak detection. (a)… (c) CPM leak detection systems. Each computational pipeline monitoring (CPM) leak detection system installed on a hazardous liquid pipeline must comply with API RP 1130 (incorporated by reference, see § 195.3) in operating, maintaining, testing, record keeping, and dispatcher training of the system. DCP’s Leak Detection Program procedures, dated November 6, 2019, were inadequate in two areas. First, DCP’s procedures did not include a process for initial testing of the Leak Detection System (LDS) to establish a baseline of performance, as required by incorporated by reference API RP 1130, Section 6.2.2 and second, DCP did not include a process for instrumentation maintenance and calibration, as required by incorporated by reference API RP 1130, Section 5.1.3. DCP provided revised Leak Detection Program procedures dated October 28, 2020, which now include a process for initial testing of the LDS that establishes a baseline of performance and a process for instrumentation maintenance and calibration. These procedures were reviewed and found to be adequate. 2 Response to this Notice This Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206.
