New Air Toxics Rule Adopted in Colorado
DENVER — The Colorado Air Quality Control Commission has enacted a new rule aimed at regulating five identified "priority" air toxics: benzene, ethylene oxide, formaldehyde, hexavalent chromium compounds, and hydrogen sulfide. These pollutants, linked to severe health risks like cancer and respiratory issues, will be officially addressed as part of an ongoing commitment to improving air quality in the state.
The commission based its decision on detailed findings from the Colorado Department of Public Health and Environment’s Air Pollution Control Division, which highlighted the sources and health impacts of these contaminants. Benzene is primarily released during oil and gas production and industrial activities, while ethylene oxide is commonly used to sterilize medical equipment. Formaldehyde emissions stem from fuel combustion and various industrial processes, whereas hexavalent chromium is associated with coal-fired power plants and metal coating. Hydrogen sulfide is emitted by several industrial sources such as petroleum refineries and landfills.
The new rule follows House Bill 22-1244, granting the commission the authority to impose stricter regulations than those set by federal standards. Carla Padilla, a local activist from the Globeville neighborhood, expressed both concern and optimism regarding the rule, noting the long-standing health issues in her community linked to air pollution.
Environmental advocates, including Harmony Cummings from the Green House Connection Center, emphasized the importance of addressing air quality for community health. While they celebrate this initial step, they recognize the need for robust health-based standards and effective enforcement in future rulemaking, scheduled for 2025.
The commission plans to reassess the list of regulated air toxics every five years, potentially expanding it to include additional harmful substances. As Coloradans look forward to improved air quality, officials and community members alike remain engaged in the fight for public health and environmental justice.
