Suncor to Conduct Testing on Flare Unit

On Thursday, December 5, Suncor’s Commerce City refinery will conduct testing on one of its flare units in Plant 1. The work will begin at 8 a.m. and completed by approximately 6 p.m. As a result of this activity, increased flaring with potentially larger flames and smoke could occur from the flare stack.  Additional updates will be provided if the refinery experiences increased flaring for an extended period of time.
