Rulemaking Rule 7.4 


The Ground Water Commission (Commission) would like to make all interested parties aware that it is proceeding with the process to possibly amend Rule 7.4 of the Rules and Regulations for the Management and Control of Designated Ground Water (Designated Basin Rules).  The current Designated Basin Rules are available to view and download here

The purpose of the proposed amendment to Rule 7.4 is to prevent a well from increasing depletions of designated ground water beyond the well’s historical depletions when changing the description of irrigated acres allowed to be irrigated by the well.  

The Commission provided pubic notification of the proposal to amend the rule and provided an opportunity for public input designed to give Stakeholders – all who have an interest in Designated Ground Water and may be affected by the change in the rule – the opportunity to present their thoughts, ideas, and reasoned opinions on the proposed change.

The proposed change to Rule 7.4 proposed by the Staff of the Commission and presented to the Commission at its August 11, 2017 meeting required a historical use analysis for all changes of description of irrigated acres.  In the August 11 meeting the Commission gave approval to Staff to proceed with the formal process to change the rule.  After further considering comments made at the August 11, 2017 meeting, Staff of the Commission revised the proposed change so that a historical use analysis is not required if the change of description and number of acres is to those acres under which the irrigation right was established and which have been continued to be irrigated since the right was established. 

The Commission is going to hold a public rulemaking hearing during its quarterly November 3, 2017 meeting.  A notice of the rulemaking hearing was published by the Secretary of State in the Colorado Register on September 25, 2017.  The Commission’s Notice of Public Rulemaking Hearing (case no. 17GW04), the wording of the rule change proposed by Staff as published in the Colorado Register, and a proposed Statement of Basis and Purpose, all dated September 5, 2017, are available to view and download hereAlso available through the aforementioned link are the requests for party status, prehearing statements submitted by the parties to the hearing, and written comments received by persons not parties to the hearing. 

PLEASE NOTE:  The location of the November 3, 2017 public rulemaking hearing is being changed from that published in the Colorado Register and stated in the Notice of Public Rulemaking Hearing, to:  Town of Castle Rock Utilities Department, Building 183 (enter through Gate C), 175 Kellogg Ct., Castle Rock, CO 80109.
