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


Midstream segment Emission Reduction Report

The Midstream Steering Committee’s proposed Midstream Segment Emission Reduction report is now available in English and Spanish. It is now open for a 30-day public comment period between May 9, 2024 and June 10, 2024. To provide a comment, please visit our comment portal.

Public Comments close on Monday, June 10, 2024, at 5 p.m. MDT.

During the public comment period, you are invited to join public feedback sessions focused on the Midstream Steering Committee's report. All are welcome to participate and share verbal feedback, but please focus your comments on the report and upcoming rulemaking. Please review the report before the meeting. These meetings will not include a presentation or question and answer session. These feedback sessions will be recorded.


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. This equipment includes engines, turbines, heaters, reboilers, and boilers.

The Colorado Air Pollution Control Division and the Midstream Steering Committee are conducting a planning process to reduce greenhouse gas emissions from midstream fuel combustion equipment statewide. The majority of these midstream facilities are located in Rio Blanco, Garfield, and Weld counties. This planning process was established by Regulation No. 7, Part B, Section VII., and will culminate in a regulatory proposal by the Air Pollution Control Division to the Air Quality Control Commission in 2024. This process advances ongoing actions by the state to meet greenhouse gas reduction targets for the industrial sector in the 2021 Greenhouse Gas Pollution Reduction Roadmap


Interactive Map of Midstream Locations, DI Communities, and 2021 Emissions

Interactive map dashboard 

This map tool shows midstream fuel combustion equipment GHG emissions in 2021 statewide, and also within the boundaries of the May 2023 definition of "disproportionately impacted communities" (per §24-4-109(2)(b)(II), C.R.S.). Data was collected from midstream company cERPs in 2023.

Use the dropdown menu at the top right to toggle between displaying (1) all midstream locations in 2021, (2) midstream locations within DI Community boundaries, or (3) midstream locations in census blocks with EnviroScreen cumulative impact score over 80.

Midstream Steering Committee

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

Register to receive email updates about this process by completing the meeting registration form.

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 and presented that report to the division in March 2024. For information on the duties, deadlines, and representation of the Midstream Steering Committee, refer to the committee charter.


Community Sessions on Midstream Greenhouse Gas Reduction

Community Sessions are complete, but you can register to receive email updates about additional opportunities by completing the Midstream Greenhouse Gas Planning Community Sessions form

To support community understanding and engagement with this planning process, the division convened Community Sessions on Midstream Greenhouse Gas Reduction Planning.

These community sessions were held separately from the Midstream Steering Committee and were intended to help the community understand what the committee was working on and provide feedback. Recordings of the division presentation portion of the sessions are available:


Company emission reduction plans

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

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

In March 2023, the Midstream Steering Committee published a guidance document and workbooks for the development of the cERP by each midstream segment owner or operator:

The division presented a one-hour training session targeted to midstream owners or operators in April 2023:
