<br />tor. Dick Gamewell <br />June 22, 1982 <br />Page - Five - <br />Response to Comment No. 4 - Referring to Cotter response to Comment <br />No. 3, above, all rock processed by the ore sorter is washed free of <br />fines. In addition, it should be noted that the ore shipment pad is <br />located in a watershed that drains away from the reservoir and the <br />creek. The pad is in a different drainage than Ralston Creek arrd <br />Ralston Reservoir, about 3/4 of a mile from the nearest shore of i;he <br />reservoir and about one mile from the confluence of the creek and <br />reservoir. <br />Colorado State Department of Highways <br />Comment No. 1 - "No method of containment of spills that niay or_cur• on <br />state highways on rainy or snowy days is provided. Contamination of <br />runoff should be accounted for in the spill containment procedures." <br />Response to Comment No. 1 - If a spill occurs on a paved road when it <br />is raining or snowing, it is expected that the volume of runoff tFat <br />comes into contact with ore relative to the total volume of runoff' <br />adjacent to the spill will be quite small, as will the increase iri <br />uranium concentrations in spill runoff water since the uranium in the <br />ore does not readily go into solution when exposed to water only. <br />Accordingly, the spill containment plan described in Section 5.3 cf <br />the revised application is considered effective. <br />Comment No. 2 - "Continual monitoring of roadside radioactivity levels <br />through densly populated areas should be done to assure knowledge of <br />unsafe levels of radioactivity." <br />Response to Comment No. 2 - The trailers of all ore haul trucks travel- <br />ling between the ore loadout pad and the mill are covered by a tarp <br />so that ore cannot become wind blown. <br />Division of Health - Colorado Department of Health <br />Comment No. 1 - "One concern of mine is also expressed throughout the <br />report; namely, how efficient is this sorter in separating waste from <br />ore if the belt speed is 200 feet per minute with a wide variation irr <br />size of the material on the belt. It takes a lot of air to move a <br />6 inch rock off the belt." <br />Response to Comment No. 1 - Based on daily analysis, by T-probe, the <br />ore sorter is 100% efficient with respect to the removal of ore from <br />waste. <br />
