85-2-312. Terms of permit. (1) (a) The department may issue a permit for less than the amount of water requested, but may not issue a permit for more water than is requested or than can be beneficially used without waste for the purpose stated in the application. The department may require modification of plans and specifications for the appropriation or related diversion or construction. The department may issue a permit subject to terms, conditions, restrictions, and limitations it considers necessary to satisfy the criteria listed in 85-2-311 and subject to subsection (1)(b), and it may issue temporary or seasonal permits. A permit must be issued subject to existing rights and any final determination of those rights made under this chapter.

(b) If the permit is for use of water with a point of diversion, conveyance, or place of use on national forest system lands, the permit is subject to any written special use authorization required by federal law to occupy, use, or traverse national forest system lands for the purpose of diversion, impoundment, storage, transportation, withdrawal, use, or distribution of the water under the permit and any terms, conditions, and limitations related to the use of water contained in any special use authorization required by federal law.

(2) The department shall specify in the permit or in any authorized extension of time provided in subsection (3), the time limits for commencement of the appropriation works, completion of construction, and actual application of the water to the proposed beneficial use. In fixing those time limits, the department shall consider the cost and magnitude of the project, the engineering and physical features to be encountered, and, on projects designed for gradual development and gradually increased use of water, the time reasonably necessary for that gradual development and increased use. The department shall issue the permit or authorized extension of time subject to the terms, conditions, restrictions, and limitations it considers necessary to ensure that the work on the appropriation is commenced, conducted, and completed and that the water is actually applied in a timely manner to the beneficial use specified in the permit.

(3) The department shall by rule or by condition to a permit establish a process allowing for the extension of the time limits specified in the permit for commencement of the appropriation works, completion of construction, and actual application of water to the proposed beneficial use.

(4) (a) If commencement of the appropriation works, completion of construction, or the actual application of water to the proposed beneficial use is not completed within the time limit specified or within an extension of that time limit, the permit expires.

(b) The department shall reinstate an expired permit if the permittee files a written reinstatement request and a project completion notice on forms provided by the department. The reinstatement request and project completion notice must establish the amount of water actually applied to the proposed beneficial use prior to expiration of the permit. Reinstatement of an expired permit under this subsection (4)(b) may not exceed the amount of water actually applied to the proposed beneficial use under the terms of the permit prior to expiration of the permit.

(c) The department shall reinstate the full amount of water authorized by the expired permit, including any portion that was not actually applied to the proposed beneficial use prior to expiration of the permit, if the permittee:

(i) files a written reinstatement request with the department on a form provided by the department;

(ii) proves by clear and convincing evidence that the failure to comply with the permit time limit was the result of excusable neglect; and

(iii) demonstrates that the requirements for an extension of the time limit as set forth by rule or permit condition are satisfied.

(d) A written reinstatement request for an expired permit must be filed within 2 years of the expiration of the permit time limit.

(e) A permit must be reinstated no more than once pursuant to this subsection (4) if the criteria in this subsection (4) have been met. A reinstated permit under subsection (4)(c) must establish time limits for commencement of the appropriation works, completion of construction, and actual application of the water to the proposed beneficial use.

(5) The original of the permit must be sent to the permittee, and a copy must be kept in the office of the department in Helena. The department shall retain an expired permit in the centralized record system for 2 years.
