Remediation Process Guide

October 2020


As the Canada Energy Regulator (CER), we oversee our environmental protection mandate throughout the lifecycle of Facilities that are regulated under our jurisdiction. Environmental protection activities include the management of Contamination by companies operating Facilities that are under our jurisdiction. Companies must comply with all laws related to the reporting, management, remediation, and monitoring of contamination.

The 2020 CER Remediation Process Guide provides the framework for companies to demonstrate they are effectively anticipating, preventing, managing and mitigating the Adverse Effects of Contamination related to their Facilities. Find information within the Guide on our process for the submission of remediation process documents, and guidance on how to maintain compliance with our requirements.


See the Bulletins published on Third Party Contamination (March 2023) and the updated Closure Report Worksheet (Appendix H) version 2.0 (June 2023).
