Ms. Michelle L. Hatcher <br />March 7, 2011 <br />Page 4 of 6 <br />2. Well permit no. 50425-F was obtained for the current uses and exposed surface area of <br />the pit in accordance with C.R.S. § 37-90-137(2) and (11). The Applicant is required to <br />maintain a valid well permit for the current uses at this site. <br />3. The total surface area of the groundwater exposed at the Geisert Pit after December 31, <br />1980 must not exceed 40.6 acres, resulting in a maximum annual evaporative loss of 118.9 <br />acre-feet. <br />4. The annual total product mined at the Geisert Pit shall not exceed 150,000 tons per year, <br />resulting in 4.4 acre-feet of water lost with the mined aggregate and 33 acre-feet of water <br />removed by the "first fill". <br />5. Total consumption at the Geisert Pit must not exceed 156.3 acre-feet per year, unless an <br />amendment is made to this plan. <br />6. Approval of this plan is for the purposes as stated herein. Any additional uses for which <br />the water may be used must first be approved by this office. <br />7. The replacement water that is the subject of this plan cannot be sold or leased to any <br />other entity. As a condition of subsequent renewals of this substitute water supply plan, <br />the replacement water must be appurtenant to this site until a plan for augmentation is <br />obtained. All replacement water must be concurrent with depletions in quantity, timing <br />and locations. <br />8. The name, address and phone number of the contact person who will be responsible for <br />the operation and accounting of this plan must be provided with the accounting form to <br />the division engineer and water commissioner. <br />9. Adequate accounting of depletions and replacements must be provided to the division <br />engineer in Greeley (Div1Accountin-gO-state.co.us) and the water commissioner (George <br />Varra at GeorAe.Varra(a_state.co.us) on a monthly basis or other interval acceptable to <br />both of them. The accounting form provided with your application is subject to <br />modification and approval by the division engineer. All amounts shall be in acre-feet. <br />10. If reclamation of the mine site produces a permanent water surface exposing <br />groundwater to evaporation, an application for a plan for augmentation must be filed with <br />the Division 1 Water Court at least three (3) years prior to the completion of mining to <br />include, but not be limited to, long-term evaporation losses. If a lined pond results after <br />reclamation, replacement of lagged depletions shall continue until there is no longer an <br />effect on stream flow. Granting of this plan does not imply approval by this office of any <br />such court application(s). <br />11. In accordance with the letter dated April 30, 2010 (copy attached) from the <br />Colorado Division of Reclamation, Mining, and Safety ("DRMS"), all sand and <br />gravel mining operators must comply with the requirements of the Colorado <br />Reclamation Act and the Mineral Rules and Regulations for the protection of water <br />resources. The April 30, 2010 letter from DRMS requires that you provide <br />information to DRMS to demonstrate you can replace long term injurious stream <br />depletions that result from mining related exposure of ground water. The DRMS <br />letter identifies four approaches to satisfy this requirement. If the information you <br />are providing to DRMS is included under the approaches numbered 1 - 3, a copy <br />of that information needs to also be provided to this office (the Division of Water <br />Resources). <br />If the information you are providing to DRMS is pursuant to approach no. 4, you <br />will need to provide additional documentation to this office that specifies what
