The Suncor refinery, located on Brighton Boulevard near Sand Creek in Commerce City, is the only major petroleum refinery in Colorado. Suncor is classified as a "major source" based on its pollutant emission levels, so it is required to maintain a Title V Operating Permit. The facility is frequently a subject of significant public attention. In an effort to be transparent and responsive, the Air Pollution Control Division created this webpage to house the most up-to-date information.
