- Q11. How are rules adopted, amended, or repealed?
- A11. The first step to adopt, amend, or repeal regulations is for an agency to publish a Notice of Proposed Rulemaking in the Colorado Register. (There are limited instances where an agency may adopt a temporary or emergency rule without publishing a notice; however, it must still publish the adopted rule.)
- The Notice of Proposed Rulemaking contains the date, time, and location of the hearing, which must be held at least 20 days after publication in the Colorado Register The Register is published on the 10th and 25th of each month. The notice also contains the statutory authority for the proposed action, the subject matter
of the proposed rulemaking, and the agency’s contact information. It may also contain the text of the proposed rules and other information.
- The agency then allows time for public comment and reviews before taking final action. A newly adopted, amended, or repealed rule must be published in the Colorado Register before it can take effect. The rule may become effective twenty (20) days after publication or later, if desired. An emergency rule may become effective upon adoption.
- As part of the rulemaking process, the Department of Regulatory Agencies’ Office
of Policy, Research and Regulatory Reform, the Attorney General’s Office, and
the Office of Legislative Legal Services also review the rules.
- Rulemaking time periods are counted by calendar days, beginning with the day following the
action, including weekend days and holidays. The only exception is the 20-day
deadline for completion of rule-filing after adoption. If this deadline falls
on a weekend or holiday, the filing agency may file on the next business day.
- A flowchart (PDF) that shows how the rulemaking process works is available. Other process diagrams and rulefiling schedule calculators are available on the Administrative Rules home page.
