Proposed Rules

  •

    The following are summaries and other information related to Proposed Rules that the Missouri Department of Natural Resources has submitted to the Secretary of State for Publication in the Missouri Register. These rules will not go into effect until the public has had an opportunity to submit written comments, and to attend a public hearing if one is scheduled.

    Any person may offer comments on a Proposed Rule. The instructions for submitting comments, and the location and date of a hearing if one is scheduled, are located after the text of each rule. Please note that the official text of a Proposed Rule is the version that appears in the Missouri Register, not the draft copy on this site.

    Information on Rules in Initial Development follows the Proposed Rules information. The dates provided in this section are subject to change.

    We hope you find this site helpful and informative.
