A Comparative Assessment of Albertas Oil and Gas Methane Emissions Under the ECCC rules and AERS Draft Directive 060 (1/2/2020 correction)

The analysis estimates that by 2025, ECCC regulations would reduce Alberta's methane emissions by 36% compared to a baseline, while AER's Draft Directive 060 would achieve a 23% reduction. The report details specific abatement assumptions for leaks, pneumatics, and venting, noting that AER's approach to leak detection and venting limits results in lower overall reductions than the ECCC framework.

• Total projected methane emissions reductions for Alberta in 2025 are significantly higher under ECCC rules (36%) than under AER Draft Directive 060 (23%) when compared to the uncontrolled baseline.
• The most substantial difference in abatement occurs in venting, where ECCC rules are projected to reduce emissions by 67% (8.71 MMT CO2e), whereas AER rules would reduce them by 23% (3.03 MMT CO2e).
• For leak detection and repair (LDAR), the analysis assumes a 70% reduction for sites with three instrument-based inspections per year and a 40% reduction for those with one; however, audio, visual, or olfactory (AVO) inspections for well sites are assigned a 0% abatement percentage as they are considered generally ineffective.
• Regarding pneumatic controllers, the analysis assumes a 68% reduction for conversions from high-bleed to low-bleed controllers under DD 060, with a projected 95% device retrofit rate.
• Analysis of Alberta venting data from 2013-2017 indicates that a 3,000 m3/month site limit for new sites would reduce emissions by an average of 35%, while a 15,000 m3/month limit for existing sites would reduce them by 15%.
