Key takeaways
- Alberta requires two inspections per year for pneumatic chemical injection pumps, with penalties for missed inspections
- Operators must demonstrate monthly compliance with overall vent gas (OVG) limits under Directive 060
- Projects without per-pump metering face new reconciliation steps and potential discount factors
In 2025, Alberta Environment and Protected Areas issued a memorandum updating the Quantification Protocol for Greenhouse Gas Emissions Reductions from Pneumatic Devices (Version 3.0). The update changes how oil and gas operators inspect, quantify and report emissions from pneumatic chemical injection pumps.
The revisions strengthen methane verification and improve emissions accounting, but they also introduce new operational requirements related to inspection schedules, data management and emissions reporting. The practical impact of these changes is closely tied to the distribution of emissions sources within Alberta’s upstream sector. Understanding where vented emissions originate provides important context for the scale of monitoring and reporting that operators will be required to manage.
OneStop-reported emissions volumes in Alberta’s upstream sector show pneumatic devices are not a niche source: Pneumatic pumps and pneumatic instruments together represent ~50% of the 2024 OneStop total, comparable to, and collectively larger than, routine venting alone.

What the updated protocol requires from operators
Mandatory biannual inspections
Operators must conduct two inspections per year per pneumatic chemical injection pump, one in spring or summer and one in fall or winter, to prevent unaccounted methane venting.
Inspections must document stroke count and length as well as injection pressure. If operators miss an inspection, the protocol applies a discount rate penalty, starting at 2.5% and increasing with additional lapses.
Monthly OVG limit verification
Total emissions reductions from pneumatic devices, combined with total site-wide venting reported in Petrinex, must remain below the OVG limit established under Directive 060.
If operators lack precise monthly data, they must use one of two conservative estimation methods:
- Apply a 1.42 multiplier to a site’s 12-month average emissions reductions
- Assume all pumps operate at their maximum manufacturer-specified rate for the entire month
If emissions exceed the OVG limit, operators must complete reconciliation steps or regulator-approved alternatives.
Reconciled chemical injection volumes
Direct per-pump metering remains the most accurate method for quantifying injected volumes. Sites with per-pump metering do not require additional reconciliation and biannual inspections.
Sites without metering must reconcile calculated injection volumes using protocol formulas and recorded chemical delivery receipts. If operators cannot reconcile these values, must apply a 1% discount factor to emissions reductions.
Corrected emissions formulas
The protocol corrects an error in the chemical injection calculation formula. The updated version uses piston plunger area rather than piston diameter, improving volumetric accuracy.
A new standard for methane accountability
These modifications strengthen methane accounting and increase documentation requirements. Once implemented, the operational impact is immediate:
- Inspection scheduling aligns with seasonal windows
- Emissions data systems support monthly OVG verification
- Chemical inventory tracking withstands audit scrutiny
How to prepare for inspection and reporting rules
- Inventory all pneumatic chemical injection pumps
- Confirm inspection schedules for both seasonal windows
- Assess whether per-pump metering is feasible
- Validate emissions calculation tools against the corrected formula
- Review OVG tracking processes to ensure monthly compliance
Operators who integrate pump inspections into existing leak detection and repair (LDAR) surveys can reduce site visits and improve data consistency. Strong inventory management and documented workflows will be critical to maintaining compliance and protecting emissions reduction value.
