Overview
The CDPHE Air Pollution Control Division will propose a rule to the Air Quality Control Commission in early 2025 to reduce methane pollution from municipal solid waste landfills. These landfills are significant sources of methane, which is a greenhouse gas that causes climate change. Colorado identified reducing methane pollution from landfills as a near-term action to reduce greenhouse gas emissions in the state’s Greenhouse Gas Pollution Reduction Roadmap 2.0.
In 2024, the division also proposed changes to Colorado’s greenhouse gas reporting requirements that would apply to municipal solid waste landfills. If the commission adopts the reporting rule in October 2024, it would support the new methane reduction requirements the division plans to propose in 2025.
Technical working group (August 2024 - November 2024)
The CDPHE Air Pollution Control Division convened a technical working group in August 2024 to help support and inform the rule proposal. The technical working group will focus on:
- Evaluating methodologies and best practices for reducing landfill methane emissions beyond federal requirements.
- Assessing enhanced methane monitoring and control requirements for landfills.
- Operating and maintenance practices and considerations for landfill gas collection and control systems.
- Streamlining reporting requirements for landfills.
Technical working group meetings
The technical working group meetings are open for public listening. Listen to each meeting live or watch recordings posted on this web page. The meetings will primarily focus on technical discussions among the working group members.

Public information meetings
The division will host public information meetings in late 2024 or early 2025 on the rule proposal. During these sessions, the division will:
- Share the concept and requirements of the rule proposal.
- Provide the opportunity for public feedback.
- Answer questions.
The division will provide registration information on this web page once the meetings are scheduled.
The division continually seeks public input before proposing any rules. Explore the division's upcoming public participation opportunities.
The division convened a technical working group with diverse expertise in:
