What is a Regulation?
A regulation is a policy or procedure created by a state agency that has an impact 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.
Rulemaking Procedure
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.
Rulemaking Hearing Announced

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.

Public Comment

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.

How Do I Find Out More?
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.
Rulemaking Hearing

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.
