What You Need to Know About British Columbia Methane Limits for 2023 Reporting

The new Oil and Gas Commission (OGC) source-specific vent gas limits and requirements came into effect on January 1, 2022, for reporting that starts on May 31, 2023. Permit holders are required to start the data collection in 2022 to assess compliance and prepare for reporting in 2023.

The British Columbia OGC is responsible to regulate oil and gas activities in the Province under the Oil and Gas Activities Act. The new OGC venting requirements were published in the Drilling and Production Regulation (B.C. Reg. 282/2018), last amended on March 4, 2021. The Flaring and Venting Reduction Guideline was also updated on April 2021, to support the new requirements stated in the Drilling and Production Regulation (DPR). 

The last amendments to the Flaring and Venting Reduction Guideline affect the equipment limits and monitoring requirements for sources of natural gas venting. Limits vary and depend on the date of installation of the equipment, type of facility and/or the nature of the equipment or operation. The guidelines detail the upcoming requirements for storage tanks, compressor seals, pneumatic instruments, and pneumatic pumps. The leak monitoring and reporting requirements already came into effect on January 1, 2020, and permit holders must have submitted the first leak data collection report by May 31, 2021. As of today, OGC’s methane regulations are undergoing a stakeholder review.

A set of templates required by OGC to report venting from compressor seals, storage tanks, pneumatic instruments, and pneumatic pumps will be available on the OGC website closer to the first submission deadline in 2023.



The following is a summary of the regulatory specific limits and requirements for methane reporting in British Columbia:
