Air Pollution Control Division Minor Source Permit Modeling

The Colorado Department of Public Health and Environment is in the process of reviewing and improving its minor source modeling and permitting program. 

The process is multifaceted and provides ample ways for scientific experts and the public to participate. The goal is for the process to be inclusive, science-based, and transparent, elevating innovation and creative problem solving. 

As part of the process, we convened a group of scientific and other subject matter experts in air quality modeling and air quality monitoring. From November 2021 to March 2022, CDPHE’s Air Pollution Control Division (APCD) convened the Minor Source Permit Modeling Subject Matter Expert (SME) Panel to work collaboratively to recommend modeling processes and guidelines that ensure Colorado has a cohesive and justified approach to modeling and permitting of minor sources that meet US Environmental Protection Agency (EPA) National Ambient Air Quality Standards (NAAQS) and Colorado air quality targets. In April 2022, the Panel completed its work and provided its report to the APCD. 

Since receiving the report, APCD has reviewed the recommendations and conferred with the Attorney General’s Office.  As a result of this review, APCD has concluded that it will advance the consensus recommendations for further consideration during the second phase of this process.

The department is now soliciting public and stakeholder feedback on the panel’s recommendations, along with feedback on the APCD’s Interim Guidance for minor source modeling.  The public is asked to provide comments to APCD on the Panel's recommendations and APCD’s Interim Guidance by July 22, 2022. Want to provide attachments with your comments? Email us at cdphe.commentsapcd@state.co.us

Additionally, APCD hosted two public listening sessions on June 13, 2022 from 1 - 3 p.m. and July 7, 2022 from 6 - 8 p.m.  These meetings provided another opportunity for the public to learn more about the Interim Guidance, as well as the recommendations from the Panel being considered by APCD for inclusion in the final guidance.  The public had the opportunity to provide input to APCD during these meetings. The recording and presentation file of the June 13 session are available here. The recording and presentation file of the July 7 session are available here.

Please see this link for the full text of the APCD Minor Source Permit Modeling SME Panel Report.

Final Guidance – Following the Public Input period, APCD will review all comments and make further revisions to the guidance as appropriate.  APCD anticipates finalizing the final guidance document by fall 2022 due to the large volume of comments received, and will post it on the APCD website.
