Second Regular Session Sixty-eighth General Assembly STATE OF COLORADO INTRODUCED LLS NO. 12-0677.01 Jennifer Berman x3286SENATE BILL 12-142 SENATE SPONSORSHIP Brophy, HOUSE SPONSORSHIP Sonnenberg, Senate Committees House Committees Agriculture, Natural Resources, and Energy A BILL FOR AN ACT Concerning the creation of pilot projects to empower the state engineer to reduce augmentation requirements. Bill Summary (Note: This summary applies to this bill as introduced and does not reflect any amendments that may be subsequently adopted. If this bill passes third reading in the house of introduction, a bill summary that applies to the reengrossed version of this bill will be available at http://www.leg.state.co.us/billsummaries.) The bill authorizes the state engineer to reduce, temporarily, augmentation requirements in areas where groundwater levels are at or near historic high levels of groundwater saturation through the creation of 3 pilot projects. Be it enacted by the General Assembly of the State of Colorado: SECTION 1. In Colorado Revised Statutes, add 37-80-103.5 as follows: 37-80-103.5. Reduced augmentation pilot projects - repeal. (1) The state engineer may identify and select three contiguous geographic areas, each of which may be up to eighteen square miles in size and each of which must be entirely within the South Platte river basin, to participate in a pilot project in which augmentation requirements may be temporarily reduced. The purposes of the pilot projects are to: (a) Give the state engineer flexibility to reduce augmentation on an annual basis in geographic areas experiencing historically high levels of groundwater saturation; (b) Reduce flooding, where such flooding has been determined to be more likely than not exacerbated by current augmentation levels in those geographic areas; (c) Compile data and analyze the data collected; and (d) Assess the effects that reduced augmentation has on the water levels of the selected geographic areas. (2) The areas chosen by the state engineer for a pilot project must provide sufficient evidence that augmentation is more likely than not exacerbating the historically high levels of groundwater saturation. The state engineer may reduce augmentation requirements in the pilot project areas annually for up to a twelve-month period. During that twelve-month period, an augmentation plan in a pilot project area retains the same augmentation credits that it would have had for full augmentation in the pilot project area. (3) The state engineer shall provide notice, and allow for comments, according to the same notice and comment process as that set forth in section 37-92-308 concerning substitute water supply plans. Owners of water rights and decreed conditional water rights who have subscribed to a substitute water supply plan notification list created pursuant to section 37-92-308 (6) must receive written notice of a proposed reduced augmentation plan in a selected geographic area within their water division. Owners of water rights and decreed conditional water rights may file comments on the reduced augmentation plans within their water division pursuant to section 37-92-308 (5). The state engineer, after consideration of the comments received, shall determine whether the operation and administration of the reduced augmentation plan will prevent injury to other water rights and decreed conditional water rights, and shall notify all parties pursuant to the requirements set forth in section 37-92-308 (5) (c). (4) The state engineer shall assess the effects that reduced augmentation has on the groundwater levels of the selected geographic areas by compiling data and analyzing the data collected. (5) The state engineer maintains the authority to modify the augmentation requirements throughout the implementation of the pilot projects, including the authority to increase, temporarily, the augmentation requirements up to the level of the decree to ensure water levels in the selected areas do not drop to levels that would cause injury to senior appropriators. (6) This section is repealed, effective December 31, 2017. SECTION 2. Safety clause. The general assembly hereby finds, determines, and declares that this act is necessary for the immediate preservation of the public peace, health, and safety.
