41-3-915. Control areas; hearing to determine adequacy of water for all appropriators; corrective controls generally; agreements in lieu of controls.| (a) After designation of an area as a control area by the board, the state engineer may temporarily adopt any of the corrective controls provided for by this section, where it appears that immediate regulation is required. After the well adjudication procedure has been completed, the state engineer may, on his own motion, and shall on the petition of twenty (20) appropriators or of one-tenth of the appropriators of water from a control area, cause a hearing to be held before the state engineer and the control area advisory board to determine whether the underground water in the area is adequate for the needs of all appropriators of underground water in such area. Public notice of the time and place of the hearing shall be published once in a newspaper circulated in the area not more than thirty (30) days before the time set for the meeting. If the state engineer finds after the hearing, and after receiving the advice of the control area advisory board, that the underground water in the control area is insufficient for all of the appropriators, he may by order adopt one (1) or more of the following corrective controls:  (i) He may close the controlled area to any further appropriation of underground water, in which event he shall thereafter refuse to grant any applications for a permit to appropriate underground water in that area, provided, that such area may be reopened to appropriations at any time the state engineer shall find on the basis of additional evidence that there is unappropriated water in the area, in which event the state engineer shall reconsider all applications for permits refused on the grounds of the order closing the area;  (ii) He may determine the permissible total withdrawal of underground water in the control area for each day, month or year, and, insofar as may be reasonably done, he shall apportion such permissible total withdrawal among the appropriators holding valid rights to the underground water in the control area in accordance with the relative dates of priority of such rights;  (iii) If he finds that withdrawals by junior appropriators have a material and adverse effect upon the supply available for and needed by senior appropriators, he may order such junior appropriators to cease or reduce withdrawals forthwith;  (iv) If he finds that cessation or reduction of withdrawals by junior appropriators will not result in proportionate benefits to senior appropriators, he may require and specify a system of rotation of use of underground water in the controlled area;  (v) He may institute well spacing requirements if permits are granted to develop new wells.  (b) The state engineer shall cause a copy of any such order to be served upon each person affected thereby in the manner provided for service of process in civil actions.  (c) Appropriators of underground water from a control area may agree to any method or scheme of control of withdrawals, well spacing, apportionment, rotation or proration of the common supply of underground water. The state engineer shall encourage and promote such agreements and supply the parties with information and advice. When the state engineer, with the advice of the control area advisory board, shall find that any such agreement, executed in writing and filed in his office, is consistent with the intent, purposes and requirements of this act, and would not be detrimental to the public interest or to the rights of other persons not parties to the agreement, he shall approve the agreement, and thereafter such agreement shall control, until terminated as hereinafter provided, in lieu of any order issued pursuant to subsection (a) of this section.  (d) Any agreement approved by the state engineer may be terminated by the terms of the agreement, by the consent of the parties, or by order of the state engineer if he finds, after investigation and a public hearing before the control area advisory board, held at least two (2) weeks after one (1) published notice in a newspaper of general circulation in each county in which a part of the control area lies, that the agreement is not being substantially complied with by the parties, or that changed conditions have made the agreement inequitable, or that the continuance of the agreement is no longer consistent with the intent, purpose and requirements of this act, or is a detriment to the public interest or to the rights of other persons not parties to the agreement.
