520185008M_Notice of Amendment_12312018_text.pdf, page 1Official PDFNOTICE OF AMENDMENT CERTIFIED MAIL - RETURN RECEIPT REQUESTED December 31, 2018 Mr. Al Walker President Anadarko Petroleum Corporation 1201 Lake Robbin Drive The Woodlands, TX 77380 CPF 5-2018-5008M Dear Mr. Walker: From August 20 through August 24, 2018, representatives of the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected Anadarko’s written Operator Qualifications (OQ) Program in The Woodlands, Texas. The OQ Program applies to all of Anadarko’s hazardous liquid assets. Based on the inspection, PHMSA has identified apparent inadequacies found within Anadarko’s (operator) written OQ procedures, as described below: 1. §195.505 Qualification Program Each operator shall have and follow a written qualification program. The program shall include provisions to: (a) … (c) Allow individuals that are not qualified pursuant to this subpart to perform a covered task if directed and observed by an individual that is qualified; … Anadarko’s OQ procedures did not establish span of control ratios, and did not consider or fully address factors that influence span of control, such as distance and noise levels. Furthermore, Anadarko personnel could not explain how the span of control ratios were established, and#

The program shall include provisions to: (a) … (g) Identify those covered tasks and the intervals at which evaluation of the individual’s qualifications is needed; … Anadarko’s OQ procedures did not establish and justify re-evaluation intervals. Instead, Anadarko used an across-the board application of extended re-evaluation intervals with no documented justification or basis. Additionally, Anadarko’s OQ program provided no basis for the re-evaluation interval chosen, and the interval is applied to all tasks regardless of complexity of the task, the critical nature of the task, or the frequency of task performance. Furthermore, Anadarko’s OQ program did not identify a minimum time-frame for re-evaluation upon failure of evaluation for a covered task, nor established how many times an individual will be allowed to attempt the requalification process before the qualification is revoked.
