Colorado Air Quality Control Commission

The Colorado Air Quality Control Commission (AQCC) is a nine-member regulatory body appointed by the Governor of Colorado ^[11][11] Campbell, Spencer. "What, Exactly, Is Colorado’s Air Quality Control Commission Doing?" 5280, 10 Aug. 2021, https://www.5280.com/what-exactly-is-colorados-air-quality-control-commission-doing/. Authorized under the Colorado Air Pollution Prevention and Control Act, the commission oversees the state's air quality program and promotes greenhouse gas abatement ^[6][6] Colorado Department of Public Health and Environment. "Air Quality Control Commission Public Comment Hearing - March 31, 2026." Colorado.gov, 2026, https://cdphe.colorado.gov/aqcc. The entity operates within the Colorado Department of Public Health and Environment (CDPHE) and reports to the Colorado General Assembly ^[6][6] Colorado Department of Public Health and Environment. "Air Quality Control Commission Public Comment Hearing - March 31, 2026." Colorado.gov, 2026, https://cdphe.colorado.gov/aqcc. Its primary mandate involves adopting cost-effective regulations to protect public health and the state’s natural resources from air pollution ^[6][6] Colorado Department of Public Health and Environment. "Air Quality Control Commission Public Comment Hearing - March 31, 2026." Colorado.gov, 2026, https://cdphe.colorado.gov/aqcc. The commission relies on the Air Pollution Control Division (APCD) for research and technical support, which has a staff of over 800 employees and manages a budget largely funded by stationary source fees ^[12][12] Colorado Department of Education.

Historical Background

The Colorado General Assembly established the AQCC in 1970 following the passage of the original Colorado Air Pollution Prevention and Control Act ^[7][7] Regional Air Quality Council. "Air Quality Control Commission - RAQC." RAQC.org, 3 Sept. 2024, https://raqc.org/aqcc/. Legislators designed the commission to serve as the state’s primary rule-making authority for air quality, replacing a less centralized system ^[7][7] Regional Air Quality Council. "Air Quality Control Commission - RAQC." RAQC.org, 3 Sept. 2024, https://raqc.org/aqcc/. In 1979, the state expanded the commission’s powers through the Colorado Air Quality Control Act to better align with federal Clean Air Act standards ^[8][8] Regional Air Quality Council. "AQCC - RAQC - Regional Air Quality Council." RAQC.org, 3 Sept. 2024, https://raqc.org/aqcc-raqc-regional-air-quality-council/. A significant structural change occurred in 2019 when the Climate Action Plan to Reduce Pollution mandated specific greenhouse gas reduction targets of 50 percent by 2030 and 90 percent by 2050 ^[11][11] Campbell, Spencer. "What, Exactly, Is Colorado’s Air Quality Control Commission Doing?" 5280, 10 Aug. 2021, https://www.5280.com/what-exactly-is-colorados-air-quality-control-commission-doing/. This law shifted the commission’s focus from traditional criteria pollutants toward aggressive climate mitigation and environmental justice ^[11][11] Campbell, Spencer.

Current Events

In February 2026, the AQCC unanimously adopted revisions to Regulation 7 to align state methane standards with the 2024 U.S. EPA Methane Rule ^[4][4] "Colorado Strengthens Oil and Gas Air Quality Regulations." Environmental Defense Fund, 20 Feb. 2026, https://www.edf.org/media/colorado-strengthens-oil-and-gas-air-quality-regulations-and-clarifies-requirements-inspections. These rules require annual instrument-based leak inspections at all oil and gas well sites, including low-producing facilities, starting in May 2026 ^[4][4] "Colorado Strengthens Oil and Gas Air Quality Regulations." Environmental Defense Fund, 20 Feb. 2026, https://www.edf.org/media/colorado-strengthens-oil-and-gas-air-quality-regulations-and-clarifies-requirements-inspections. On March 31, 2026, the commission held a public hearing regarding a Title V operating permit renewal for the Cripple Creek and Victor Gold Mine ^[6][6] Colorado Department of Public Health and Environment. "Air Quality Control Commission Public Comment Hearing - March 31, 2026." Colorado.gov, 2026, https://cdphe.colorado.gov/aqcc. The commission has scheduled another major rulemaking session for April 15-17, 2026, to consider Regulation 30 ^[2][2] "Colorado Moves to Regulate Cancer-Causing Air Toxins."

This proposed package would establish the state's first health-based emission limits for five priority toxic air contaminants: benzene, ethylene oxide, formaldehyde, hexavalent chromium, and hydrogen sulfide ^[2][2] "Colorado Moves to Regulate Cancer-Causing Air Toxins."

Additionally, the AQCC is reviewing a proposal to increase industrial permit and emission fees by up to 70 percent to address a projected $28.8 million budget deficit in the Stationary Sources Control Fund by 2027 ^[13][13] "Colorado air regulators propose higher fees for pollution permits and reports."
