Dear Mr. Yu:
- Canada Energy Regulator (CER) Audit Close-out Letter
Enbridge Pipelines Inc. (Enbridge) – Control Room Management
The CER conducted an operational audit of Enbridge as per section 103 of the Canadian Energy Regulator Act (S.C. 2019, c. 28, s. 10) (CER Act) to evaluate the company’s control room management of liquid pipelines.
The objectives of the audit were to verify that Enbridge has developed and implemented a pipeline control system and leak detection system in accordance with the requirements of the Canada Energy Regulator Onshore Pipeline Regulations (SOR/99-294) (OPR) and CSA Z662 – Oil and Gas Pipeline Systems and verify that the control room operation and maintenance processes are effectively integrated within the company’s management system.
The audit was conducted during the period from 7 June to 12 September 2019. A final audit report was issued on 11 March 2020 in which one Non-Compliant finding was identified. Enbridge provided a corrective and preventive action plan (CAPA Plan) to address the non-compliance on 19 March 2020, which was approved by the CER on 23 April 2020.
Following the approval of a CAPA Plan, the CER verifies that the corrective and preventive actions in the plan are implemented in accordance with the details committed to within the approved plan. Upon verification by the CER staff that CAPA Plans are implemented, the CER closes out the audit. Over the review period, Enbridge demonstrated that it had completed its corrective and preventive actions in accordance with the approved CAPA Plan.
With the issuance of this letter, the CER considers the audit of Enbridge Control Room Management to be closed. The CER reminds Enbridge that once CAPA Plans are closed, they are considered to be implemented, and Enbridge is accountable to maintain compliance by continuing to implement and manage its activities and facilities in accordance with the OPR and it’s committed to changes. The CER will verify ongoing compliance through future compliance verification activities.
