Memorandum to Corey Hoffmann <br />November 14, 2005 <br />• Page 8 <br />and 3) injury resulting from continued ground water impacts during the time between <br />when the initial impact occurs and the time a well permit is finally granted is not <br />prevented. <br />For all these reasons, we believe that option 2 is not a viable option, and that the Board <br />should condition the permit to include the conditions for approval identified by the Office <br />of the State Engineer in its September I5, 2005, response: <br />"The proposed operation will consume ground water by: evaporation ... ,reclamation, <br />[andJ water removed in the mined product. Based on the Lyman Henn, Inc., geotechnical <br />report dated August 19, 2005, the proposed operation will expose ground water, therefore <br />based on this new information please note the following: Prior to initiation of these uses <br />of ground water, the applicant will need to obtain either a gravel pit or other type of well <br />permit, as applicable. However, prior to obtaining a permit, an approved water supply <br />plan or decreed plan for augmentation is required. This project will also affect two <br />unnamed drainage-ways (surface water) located in the quarry area and that will flow only <br />as a result of rainfall or snowmelt. The applicant must show that no injury to other vested <br />water rights will occur as a result of this quarry project." <br />"Prior to approving a well permit, the applicant must conduct a field inspection of the site <br />and document the locations of all wells within 600 feet of the permit area. The applicant <br />must then obtain a waiver of objection from all well owners with wells within 600 feet of <br />the permit area or request a hearing before the State Engineer" <br />"The applicant has identified that the water requirement for dust control will be trucked <br />into the site. If water will be used for any other purpose at this site, the applicant will <br />need Yo document that the water was obtained from a legal source, or the water was <br />diverted in priority under a water right decreed for such industrial use." <br />5. Proposed condition: The Applicant shalt submit to the Division for approval a ground <br />water monitoring program as a modification to the permit prior to initiation of any <br />blasting or earth-moving activities at the site. The program shall contain all components <br />specified in Rule 3.1.7(7)(6). At a minimum, the monitoring program shall include <br />monitoring at both upgradient and downgradient wells drilled to the proposed final depth <br />of excavation (to be installed by the Applicant prior to any blasting and other earth-moving <br />activities), for radioactive parameters (including gross alpha, radium 226 and radium 228, <br />uranium, thorium 230 and 232), turbidity, and water levels. Monitoring wells shall be <br />sampled monthly, and the monitoring results shall be reported monthly to the Office of the <br />State Engineer, Colorado Department of Health and Environment, the City of Black Hawk <br />Water Department, the City of Central Water Department, and the Black Hawk-Central <br />City Sanitation District. Drill cuttings from the construction of the monitoring wells shall <br />be monitored and logged for radioactivity. In addition, the Applicant shall agree to <br />conduct and pay for monthly monitoring of the Black Hawk-Central City Sanitation <br />• District Wastewater Treatment Plant well for alt above-described parameters. <br />LEONARD RICE ENGINEERS, INC. <br />2000 CLaY STREET, SUITE 300, DENVER, COLORADO 8021 1-51 1 9 • PHONE (303) 4559589 • FnX (303) 45547 1 5 <br />
