Main Plant 1 Flare Reroute Project

If approved, this project would improve our flaring system and the efficiency and safety of our operations, while reducing emissions intensity.

A flare is a process safety device used to combust gas released during refinery operations. Flares are critical to safe and reliable operations at a refinery. Refinery maintenance activities such as unit start-ups and shutdowns, as well as pressure relief events, may cause the flames from the flare to be more visible.

Provided that we obtain approval of our construction permit by the Colorado Department of Public Health and Environment (CDPHE), work is scheduled to begin in late 2025 with startup expected in 2027.

We do not expect an increase in vehicle traffic or noise from this project. All work would be completed within our refinery fenceline.

Once complete, the project would result in an improved flaring system as the Main Plant 1 Flare would be removed and the emissions intensity of the flaring system would be reduced.

We continuously monitor the air surrounding our operations and provide air quality data and information for neighbors and the public. Near real-time air information from our community and fenceline monitoring systems is available on our Community Air Monitoring page and on www.ccnd-air.com.

Please refer to our website, www.suncor.com/colorado for all updates related to the project. Suncor plans to host information sessions regarding this project in early 2025. Watch for additional information.

The construction permit will be subject to a regulatory-required public comment period, which is coordinated by the CDPHE. We are committed to following CDPHE’s processes. Please contact [email protected] for any other project-related questions.
