Project Safety

The ACTL pipeline will be designed, constructed, operated and maintained using best practices that meet or exceed all regulatory and safety standards. The ACTL pipeline will be constantly monitored. In the unlikely event of a leak, valves will automatically close to isolate the section of the pipeline to minimize the release of CO₂ and an Emergency Response Plan will be activated.

A key priority for the ACTL Project is the safety of the people living in nearby communities and the protection of the environment.  Industry best practices will be used to design, construct, operate, and maintain the Project, bringing forward the resources needed to ensure that the appropriate safety standards are followed at every stage.

The ACTL Project employed best practices in the selection of the proposed storage reservoir to ensure it meets all the requirements for safe and permanent sequestration of CO₂. With a properly selected and well-managed CO₂ storage site, the probability of CO₂ leakage is extremely remote.

Only sites with a high level of containment integrity are selected for EOR and subsequent CO₂ storage. The storage reservoir that will be used for the EOR phase of the ACTL Project will be much deeper than any usable sources of groundwater (more than 1,800m deeper), and the CO₂ will be securely contained by multiple layers of impermeable rock above the storage zone.

Up to two barriers of borehole steel casing, each cemented in place to surface, will ensure that the injected CO₂ safely reaches the deep storage formation and that shallow groundwater is protected. Once the injection of CO₂ concludes, the injection wells will be monitored for a period of time, and then plugged and abandoned to ensure the long term permanent containment of the stored CO₂.

The CO₂ is stored approximately 2 kilometres below the earth’s surface, where reservoirs previously held oil and gas for millions of years. This is well below aquifers and drinking water sources which eliminates the chance of contamination.

Storing CO₂ in depleted hydrocarbon reservoirs has been proven to be safe. The Weyburn-Midale CO₂ Project in Saskatchewan has safely injected over 16 million tonnes of CO₂ to date. The US EOR industry has safely injected over 600 million tonnes of CO₂.

The ACTL pipeline will ship CO₂ volumes from Alberta’s Industrial Heartland north of Edmonton to the Clive oil processing and gas compression facility site located over 200 km south.
