<br />The applicant shall demonstrate that during a 90-day test period the unregulated ground water inflow to <br />the pit does not exceed the Performance Standard. Demonstration of inflows less than the Performance <br />Standard shall be sufficient cause far a determination that the applicant has constructed a lined reservoir <br />and is entitled to store water. If the unregulated ground water inflow to the reservoir exceeds the <br />Performance Standard, the State Engineer shall require the reservoir to be dewatered until satisfactory <br />changes have been made to the liner to conduct another initial liner test. <br />1.0_4__ Water Budget Accountin <br />Monthly accounting shall be required as long as the liner continues to meet the Design Standard. Weekly <br />accounting (or more frequent if required by the Division Engineer) shall be required for liners which do not <br />meet the Design Standard but continue to meet the Performance Standard. Evidence of compliance with <br />the standards shall be established through a mass balance analysis accounting for inflows, outflows, and <br />change in storage. <br />If the State or Division Engineer determines that the ground water inflow (leakage rate) into the reservoir Is <br />greater than the Performance Standard, the applicant shall be required to calculate the inflow to or outflow <br />from the reservoir by means of amass-balance analysis on a 48-hour basis, and return to the stream <br />system such inflows to the pit within 48 hours, without such water being used by applicant in any manner. <br />This 48-hour accounting shall only be for the entire period specified under the Liner Failure During <br />Operation Section (see below) and shall not be done pertnanen0y. <br />1.05 Liner Failure During Operation <br />In the event that the average daily unregulated ground water inflow to the reservoir exceeds the <br />Performance Standard for two consecutive months, as evidenced by accounting (see above), the <br />applicant or their successor and the State Engineers Office shall begin to consult regarding the probable <br />cause of the unregulated ground water inflow, and the appropriate actions to be taken in response thereto. <br />If the State or Division Engineer and the applicant cannot reach an agreement on the appropriate actions <br />to reduce the unregulated ground water inflow to less than the Performance Standard within nine months <br />of the beginning of the consultations, the State or Division Engineer shall provide written notice to the <br />applicant of their determination to correct this problem. The 48-hour accounting shall begin following the <br />two consecutive months that the Performance Standard is exceeded and shall continue until the applicant <br />has demonstrated that the Performance Standard has been met Applicant shall have two (2) years from <br />the date of such written notice of liner failure to repair the liner to an inflow Less than the Performance <br />Standard. If satisfactory repairs are not completed within the two year period, no new water shall be stored <br />in the reservoir until either. 1) the repair Is made; 2) the Issue is decided by the Water Court under <br />retained jurisdiction, or, 3) the State Engineer's Office otherwise grants permission for storage to continue. <br />The State or Division Engineer may declare the reservoir a well requiring a well permit <br />1.06 Legal Storaoe of Water <br />Water shall not be impounded in the reservoir except pursuant to lawful diversions allowed by statute or <br />decree. At all other times, all inflow of water into the reservoir from any source, including precipitation and <br />ground water inflows shall be removed by the applicant The water can be removed by draining, pumping, <br />or other means, and released to the stream system, without use by the applicant in any manner. The <br />applicant shall install the necessary measuring devices, Including but not limited to, staff gauges In the <br />reservoir and account on a monthly basis (or more frequently if required) for Inflow and outflow, <br />Page 2 of 3 <br />
