Greenhouse gas reduction planning for oil and gas midstream fuel combustion equipment


Greenhouse gas emissions from midstream

The operation of fuel combustion equipment in the oil and gas midstream segment is a significant source of greenhouse gas emissions. The equipment includes engines, turbines, heaters, reboilers, and boilers. The majority of midstream facilities in Colorado are located in Rio Blanco, Garfield, and Weld counties.

The Colorado Air Pollution Control Division and the Midstream Steering Committee conducted a two-year planning process to help reduce greenhouse gas emissions from midstream fuel combustion equipment statewide.  This planning process was established by Regulation No. 7, Part B, Section VII. 

The division will present a regulatory rule proposal to the Air Quality Control Commission in August 2024. 

This work advances ongoing actions by the state to meet greenhouse gas reduction targets for the industrial sector in the 2021 Greenhouse Gas Pollution Reduction Roadmap.


Midstream segment regulatory rule proposal

Join an online public meeting to learn more about ways to reduce emissions from the midstream oil and gas segment. The division will share information about the draft rule it will propose to the Air Quality Control Commission in August 2024. Questions and community feedback on the proposed plan is encouraged.


Midstream segment Emission Reduction Report

The Midstream Steering Committee’s proposed Midstream Segment Emission Reduction report is available in English and Spanish. The 30-day public comment period is now closed.

Interactive Map: Midstream locations, disproportionately impacted communities, and 2021 emissions


The interactive map shows midstream fuel combustion equipment greenhouse gas emissions statewide in 2021 within the boundaries of Colorado’s May 2023 definition of disproportionately impacted communities. Data was collected from midstream company emission reduction plans in 2023.

Use the dropdown menu at the top right to toggle between displaying:

  • All midstream locations in 2021.
  • Midstream locations within disproportionately impacted community boundaries.
  • Midstream locations in census blocks with a Colorado EnviroScreen cumulative impact score over the 80th percentile.

Midstream Steering Committee

The Midstream Steering Committee met online at least monthly between February 2022 and March 2024. View past meeting recordings

The Midstream Steering Committee was a technical working group that:

  • Developed a segment-wide report with recommendations for greenhouse gas reductions from midstream fuel combustion equipment.
  • Presented the report to the Air Pollution Control Division in March 2024. 

For information on the duties, deadlines, and representatives  of the Midstream Steering Committee, refer to the committee charter.


Community sessions on midstream greenhouse gas reduction

Community sessions completed in spring 2024. You can register to receive email updates from the Air Pollution Control Division - select “Greenhouse Gas Regulation.” 

To support community understanding and engagement with the midstream greenhouse gas reduction planning process, the division convened several online community sessions.

These community sessions were held separately from the Midstream Steering Committee and provided opportunities for Colorado communities to provide feedback.


Company emission reduction plans

By September 30, 2023, each midstream segment owner or operator statewide was required to submit a company-specific emission reduction plan, or cERP, that quantifies recent emissions and explores reduction options (Regulation No. 7, Part B, Section VII.D.4.).

Compiled cERP data and source data files are available for download:

In March 2023, the Midstream Steering Committee published a guidance document and workbooks for cERP development:
