Stakeholder comment period

We held a stakeholder comment period for these proposed regulation changes between July 30, 2025 and August 29, 2025. Additionally, we held three stakeholder meetings during this period where a stakeholder meeting presentation was provided to those in attendance.

Several comments were provided by stakeholders during the comment period. These comments will be reviewed and evaluated for consideration and incorporation into the proposed rule changes, as appropriate.

A request for rulemaking before the Colorado Board of Health is scheduled for November 19, 2025. Refer to the full rulemaking schedule for more information.
