Solid Waste proposed rulemakings and stakeholder processes


Proposed rulemakings

Pending composting regulation rulemaking change

The Solid Waste Program is currently drafting changes to Section 14 - Composting. These changes will address some of the permitting issues identified in the Organics Management Plan; specifically, by increasing the volume of Type 2 material that Conditionally Exempt Small Quantity Composting Operations can manage, and by creating a class of facility between Conditionally Exempt and Class III that is able to accept source separated organics and food residuals.

Once the amended rule has been drafted, the department will convene stakeholders to discuss and provide comments on the proposed rule. The department anticipates that the stakeholder meetings will take place in the spring and summer of 2023.

For questions about the proposed changes to the composting regulations, please contact Jace Driver at or 303.691.4059.



Producer Responsibility Stakeholder Process – Senate Bill 20-055

Senate bill 20-055 required our department to conduct a literature review on producer responsibility programs throughout the U.S. and create policy recommendations based on the findings of the literature review. After surveying stakeholders, holding two stakeholder meetings, and incorporating public comments into the draft, the final literature review and policy recommendations below were submitted on July 1, 2021 to the Colorado General Assembly.

Upcoming stakeholder outreach meetings

The Solid Waste and Materials Management Program will be hosting outreach meetings for our stakeholders during 2020 and 2021. We plan to host the stakeholder meetings in various locations throughout the state and will seek input on topics of interest before holding each meeting. Meeting content will be directed to a variety of stakeholders such as: local officials, landfill operators, recyclers, composters, local environmental health professionals, or anyone else interested in solid waste management.

We are working with the Colorado chapter of the Solid Waste Association of North America (SWANA) to offer continuing education credits to those certified through SWANA's Manager of Landfill Operations course.
