Canada's annexed "Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds (Upstream Oil and Gas Sector)" was published in the Canada Gazette, Part II, on April 26, 2018. This regulation requires the implementation of Leak Detection and Repair (LDAR) programs at Canadian onshore upstream oil and gas facilities, among other requirements.

An onshore upstream oil and gas facility contains stationary equipment that is located: on a single site, on contiguous or adjacent sites, or on sites that form a network in which a central processing site is connected by gathering pipelines with one or more well sites. The operations of an onshore upstream oil and gas facility include:

  • Extracting hydrocarbons from an underground geological deposit or reservoir
  • Providing primary processing of those hydrocarbons
  • Transporting hydrocarbons - including the storage for transportation purposes - other than for local distribution

Subject facilities include a gathering pipeline, transmission pipeline, natural gas gathering and boosting station, natural gas transmission compressor station, and natural gas processing plant.

Facilities that are applicable to this regulation are required to register their facilities before April 30, 2020, or within 120 days of when the facility begins to meet the requirements of the regulation.

Regulation compliance begins January 1, 2020 and addresses fugitive equipment leaks, venting from well completions and compressors. Compliance obligations for production venting limits at facilities with pneumatic equipment begin January 1, 2023.

What are the Requirements?

The regulations' requirements cover key fugitive and venting emission sources in the upstream oil and gas sector as described in the table below. The complete regulation is posted on Canada Gazette's website.
