Division of Minerals and (}eology August 25, 1995 Page 4 We ran a conservative estimate of the flow capacity fora 24 inch circular pipe using the . HHCaIc program designed by Eagle Poim software (see enclosed print out from program). The calculated flow rate was 3717.66 gpm. Thus, there is sufficient capacity in the culvert under County Road 36 to handle flows from dewatering and irrigation. D. .The signed letter from Alexander Grant states his commitment to fill the reservoir at the completion of mining. He intends to use part or all of his shares of the Box Elder Ditch water for the filling of the reservoir.

Now the SEO sends out the notices to the well owners. 5. Reclsmatfon Costs We should clarify the statement "These phases are neither representative of the maximum area of distwbance nor do they limit disturbance to a particular phase." Connell has wmmitted to keeping the total disturbance to a maximum of 37.3 acres as listed in Table D-1 of the application report. The phased areas designated on Exhibit C (inner phases - 13.1 acres and Phase 2 -I5.5) are used to represent the direction of mining and the general amount excavation in a yeaz. Connell anticipates they will mine between 10 and l5 acres per yeaz. The rema;*+1rg areas of disturbance will include access roads and processing and stockpiling areas.
