Suncor Water Quality Permits

Suncor

The Colorado Department of Public Health and Environment (CDPHE) has issued the final renewal permit for process water and stormwater discharges from the Suncor Oil Refinery. This permit is more protective than Suncor’s previous permit and will further protect Sand Creek and downstream waters for recreation, aquatic life, agriculture, and drinking water supply. The permit will increase the transparency of Suncor’s site operations and implement monitoring requirements and limits for dozens of toxic metals and chemicals, including per- and polyfluoroalkyl substances (PFAS). You can access the comments received and the final permit package using the buttons below.

Suncor monitors certain pollutants in the wastewater they discharge to the creek. 

Summaries of the data:

All data (except PFAS) for the CO0001147 permit is also on EPA's ECHO site:

CDPHE reviews spills associated with an entity and we consider that data and information when renewing a water quality permit. CDPHE created a Suncor spill report summary that highlights the spills most directly-related to water quality events. This summary does not include all the spills that come from Suncor.
