Lawrence, Esq. Lind, Lawrence & Ottenhoff 1011 - 11th Avenue Greeley, CO 80631 Re: Well injury analysis, S&H Mine Dear Kim: I have reviewed the proposed S&H gravel pit and the potential for injury to 16 irrigation wells and 9 domestic and stock wells. The 16 irrigation wells and 9 domestic wells are located within 1.5 miles of S&H's proposed gravel mining operation. This letter report presents the potential injury to the 16 irrigation wells and 9 domestic wells that would result from the dry-mining of 1 acre gravel cells associated with S&H's gravel mine. Figure 1 shows the location of the 16 irrigation and 9 domestic wells. The irrigation wells are used to provide irrigation water to cultivated crop land and have a long history of being used for irrigation of said crop lands. The 9 domestic wells are used to provide domestic water to numerous farm houses and also drinking water for livestock. I calculated the historic aquifer response resulting from the pumping of the 16 irrigation wells and the 9 domestic wells simultaneously using the Theis method for unsteady radial flow in an unconfined aquifer. In addition, I calculated the additional impact from the proposed S&H mine using the same Theis method. Aquifer properties were taken from the 1972 Hurr and Schneider open-file report "Hydrogeologic Characteristics of the Valley-Fill Aquifer in the Greeley Reach of the South Platte River Valley, Colorado". These properties included the aquifer saturated thickness and transmissivity. Decreed pumping rates for the 16 irrigation wells were obtained from the State Engineer's tabulation. It was assumed that the 9 domestic wells had a flow rate of 15 gallons per minute. The injury analysis for the historic analysis was predicated on the assumption that each well was pumping at it's decreed discharge rate simultaneously. The drawdown at each well was LEAF ENGINEERING EXHIBIT Hydrology ` Hydraulics " Water Resources ` Water Quality I E:\LeaN 'tasnik\Lawrence S&H well injury letter report 2.wpd • • • Lawrence S&H Well Injury Letter Page 2 calculated after 90 days of simultaneous pumping, which would be the case during a dry year. The historic drawdown for each well is the result of the effect of that particular well's pumping on itself and the commutative injury from all of the other pumping wells on that particular well. This exercise was conducted for each well. Table 1 contains a summary of the historic drawdown for each of the 16 irrigation wells and 9 domestic wells, column [2].

Drawdown calculations for the dry pit mining were taken from Dennis McGran's March 23, 2001 memorandum to Greg Roush. McGran's estimated impact from the dry pit mining was added to the historic well drawdown, column [2], in Table 1 to shows the potential injury of the gravel mining on all of the wells at the end of the 90 day pumping period for the wells and 365 days of continuous pit de-watering to a depth of 15 feet below the water table of 1 acre gravel cells. LEAF ENGINEERING Hydrology " Hydraulics " Water Resources Water Quality E:LLeaN'tasnik\Lawrence S&H well injury letter report 2.wpd • • • Lawrence S&H Well Injury Letter Page 3 It is evident from Table 1 that the proposed dry pit mining will cause increased water level drawdown in each of irrigation and domestic wells. Furthermore, when comparing this increased drawdown to the saturated thickness, column [1], in Table 1, it is my opinion that the production from each of the 16 irrigation wells will be decreased, and in some instances, surging will result. I have previously recommended that S&H limit its de-watering to periods other then the irrigation season. To avoid injury to wells in the area, I recommend the following language: 1. All de-watering pits must be a minimum of 2,000 feet from any existing irrigation, domestic or stock well. 2. S&H shall de-water only one area at a time and shall be limited to the period after irrigation has ceased in the area to March 15. Sincerely, L'AF Forrest Leaf, P.E.
