EPA Continues to Block Suncor's Air Pollution Permit in Colorado

The EPA's Denver regional office has once again blocked the renewal of a state air pollution permit for Suncor's refinery in Commerce City, Colorado, agreeing with objections from environmental groups that the state should take stronger action against carbon monoxide dangers and past plant modifications. Suncor has a history of air and water pollution violations, and while Plant 2 will be allowed to continue production, state officials must address the EPA's objections before issuing a revised permit. Environmental groups have welcomed the scrutiny on Suncor and called for increased state oversight or even the closure of the refinery.
