Rulemaking and Cost-Benefit Analysis

A regulation is a rule created by a state agency that has an impact on the regulated entity and on the public. The regulation is the state agency's action in implementing, interpreting, applying or enforcing a statute enacted by the legislature and signed into law by the Governor. Regulations range from the seemingly insignificant (the size of Swiss cheese holes) to the serious (dealing with Chronic Wasting Disease).

​​Every state agency in the Executive Branch must adhere to the rulemaking process outlined in the Administrative Procedure Act or APA (Section 24-4-101, Colorado Revised Statutes) unless explicitly exempted. The rulemaking process involves four stages: 1) Notice of Proposed Rulemaking; 2) Comment Period on Proposed Rule; 3) Hearing on Proposed Rule; 4) Final Adoption of Proposed Rule.

1. Notice of Proposed Rulemaking

 When an agency wants to promulgate a new rule or an amendment to an existing rule, it must first file a Notice of Proposed Rulemaking with the Secretary of State. The Secretary of State then publishes the Notice of Proposed Rulemaking in the Colorado Register. This publication acts as notice to the public. Due to the passage of Senate Bill 03-121, agencies must also send a copy of the proposed rule to COPRRR. If you sign-up to receive a Regulatory Notice, you will receive an e-mail telling you that a proposed rule has been submitted by an agency covering a subject matter of interest to you.

Statutorily, agencies are also required to notify any individual who has told the agency that they want to be notified of any proposed rulemaking. The individual needs to file the appropriate form with the agency. The agency then will send the notice to the individual either by ordinary mail or via electronic mail. There may be a small fee for those individuals who want to receive notice by ordinary mail.

2. Comment Period on Proposed Rule

Once the Notice of Proposed Rulemaking is filed with the Secretary of State, the public is allowed to offer comments on the proposed rule. A Colorado state governmental agency must accept and consider comments from the public before that agency can adopt, amend or otherwise change any regulation not explicitly exempted from the APA.

Regulatory Notice subscribers will receive the contact information of the individuals in the agency submitting the proposed rule so that they can send comments or get further information.

3. Hearing on Proposed Rule

At the hearing on the proposed rule, the agency accepts written and oral testimony about the rule. The testimony can be supportive of, or in opposition to, the proposed rule. Once the hearing ends, the public is no longer able to offer comments on the proposed rule unless the agency alters the proposed rule in a manner that requires the process to begin again.

4. Final Adoption of Rule

Following the hearing on the proposed rule, the agency has 180 days to file adopted rules with the Secretary of State for publication in the Colorado Register. Adopted rules go into effect twenty days after publication or on such later date as is stated in the rule.
