<br /> <br />is not intended to change the schedule from weekly to monthly. <br />Depletions resulting from pumping in any week shall be added to the <br />depletion schedule and replacements for such Bumping shall begin <br />the following week. <br />2. Precipitation Run-Off and Evaporation Repla<ement. <br />(a) In addition to the augmentation requirements set forth in <br />paragraph 1, Applicant shall deliver water to the Rito Seco to <br />augment depletions associated with the impoundment of rainfall and <br />snowfall in the areas known as the tailings impoundment area, the <br />east ore zone and the west ore zone. The quantity of augmentation <br />water to be delivered to the Rito Seco to augment these depletions <br />shall be determined by utilization of data collected from the <br />precipitation recording gauge as described in subparagraphs (c) and <br />(d) hereof. During Applicant's dewaterinq activities, Applicant <br />shall not be required to augment depletions associated with the <br />impoundment of precipitation in any area that is then being <br />dewatered. Augmentation for snowfall runoff may be delayed as <br />determined in consultation with the Division Engineer. <br />(b) In addition to the augmentation requirements set forth in <br />paragraphs 1 and 2 (aj hereof, if the groundwater level adjacent to <br />the pits is not below the pit floors, and a seepage face develops <br />'i along the pit walls, augmentation of evaporative lasses from the <br />seepage face shall be required. Replacement water requirements <br />shall be calculated weekly from groundwater levels established from <br />the nearest observation well, evaporation pan data (see <br />subparagraph (c) hereof), and estimated area of the seepage face, <br />,;'~ and Applicant shall deliver water to the Rito Seco to augment the <br />depletions. <br />(c) Applicant shall install and maintain at its expense a <br />continuously recording precipitation gauging station and a NOAA <br />approved evaporation pan to measure evaporative losses. The <br />devices will be installed within the immediate area of the plant <br />site in a manner that meets NOAA criteria for site selection and <br />data recording. The station will continuously record the amount of <br />water associated with rainfall and snowfall. <br />(d) The tailings impoundment area until reclaimed impounds <br />water from an area which may be as large as 204 acres, the west ore <br />zone area will impound water from an area that may crwer as much as <br />il0 acres, and the east ore zone area will impound water from an <br />area that may cover as mush as 20 acres. The above acreage numbers <br />are estimates and. the replacement obligation shall be based upon <br />the actual acreage that is impounded. For the purpose of <br />establishing the depletions in each of these impoundment areas, it <br />will be assumed that precipitation measured at the gauge has fallen <br />uniformly within the total acreage in each impoundment area. For <br />the months of November through April, 50~ of the estimated average <br />monthly precipitation at the project site (which the parties agree <br />
