Below are past public participation opportunities with the Air Pollution Control Division. These opportunities are no longer ongoing, but rulemakings and other public participation opportunities may be revisited for revisions.
The division holds regular events such as public listening sessions, small community conversations, tutorials, and more. The division uses these meetings to share updates, learn from community experiences, and incorporate feedback into our work protecting clean air for all Coloradans.

Building performance standards rule
- The Air Quality Control Commission adopted this rule in August 2023.
- This rule creates building performance standards to reduce greenhouse gas emissions and helps meet goals set forth by 2021 state law: Energy Performance For Buildings (House Bill 21-1286).
- The Air Quality Control Commission adopted this rule in October 2023.
- This rule provides more zero-emission vehicle options in Colorado to help improve air quality and reduce greenhouse gas emissions.
Disproportionately impacted communities permitting rule
- The Air Quality Control Commission adopted this rule in May 2023.
- This rule requires additional modeling, and/or monitoring for sources of pollution that affect communities of color, low-income residents, and communities already being harmed by pollution.
- The Air Pollution Control Division developed a facility-wide general permit for upstream oil and gas facilities in Colorado to strengthen the minor source modeling and permitting program.
Greenhouse gas air pollutant emissions notice (APEN) rule
- The Air Quality Control Commission adopted this rule in December 2022.
- The rule added greenhouse gas emissions to the list of air pollutants that must be reported through Air Pollutant Emissions Notice, or APEN, requirements. This established the necessary structure for the greenhouse gas fee rulemaking.
Greenhouse gas emissions and energy efficiency manufacturing Phase 1 (GEMM 1) rule
- The Air Quality Control Commission adopted this rule in October 2021.
- This rule establishes a greenhouse gas emission and energy audit program for specific greenhouse gas emitting manufacturing industries.
Greenhouse gas emissions and energy management for manufacturing Phase 2 (GEMM 2) rule
- The Air Quality Control Commission adopted this rule in October 2023.
- This rule requires 18 of Colorado’s highest-emitting manufacturers to collectively reduce their greenhouse gas emissions 20% by 2030, compared to 2015 levels.
Greenhouse gas intensity verification rule
- The Air Quality Control Commission adopted this rule in July 2023.
- This rule defines how certain oil and gas facilities must calculate their greenhouse gas intensity, monitor operations to ensure compliance with intensity standards, and keep records.
Interactive map of Colorado stationary air pollution sources
- The Air Pollution Control Division provided a tutorial on an interactive visual map designed to make air pollution records more transparent and accessible.
Recovered methane protocol rule
- The Air Quality Control Commission adopted this rule in November 2022.
- This rule includes protocols for recovered methane from livestock manure management systems, municipal solid waste or landfills, wastewater treatment, coal mines, and gas utility system leaks.
Severe ozone reduction planning (State Implementation Plans, or SIPs)
- The Air Pollution Control Division conducted stakeholder meetings to share basic ozone information, engage community members in the planning processes, and seek feedback on potential reduction strategies, and provide opportunities to share concerns and suggestions.
Stationary source control fund
- The Air Pollution Control Division conducted stakeholder meetings to assess improvements in efficiency for fee-funded activities and billing and accounting practices for stationary sources.
Stationary source data modernization project
- The Air Pollution Control Division conducted stakeholder meetings to help modernize the stationary source data system.
