CCND Air Monitoring program overview

Air monitoring is the measurement of compounds and particles present in the ambient air using advanced instruments and analytical methods. Suncor’s Commerce City North Denver (CCND) air monitoring stations are equipped with state-of-the-art federal equivalent method (FEM) or near-FEM sensors to collect high-quality, continuous air quality data.

The CCND air monitors measure the following:

  • Carbon monoxide (CO)
  • Hydrogen sulfide (H₂S)
  • Nitrogen dioxide (NO₂)
  • Particulate matter (PM₂.₅)
  • Sulfur dioxide (SO₂)
  • Total volatile organic compounds (TVOCs)
  • BTEX compounds (benzene, toluene, ethylbenzene, and xylenes)

The CCND Air Monitoring program was voluntarily developed in 2021 in coordination with regional air monitoring networks and input from the public and the Colorado Department of Public Health and Environment. Suncor engages Onterris, a third-party consultant, to operate and maintain the program, conduct health risk assessments, and publish monitoring reports.
