<br />Page 17 <br />would be from a storm event in excess of the 100-year 24-hour event, plus an additional 0.~ <br />inches of precipitation during such an event. The applicant will only be required, by the act, <br />to construct permanent sediment ponds to handle the ] 00-year event. <br />l5. "How will the applicant replace water lost due to potential evaporation from the ground <br />water exposed by the mine pit?" <br />(Clean Water Action, Env. Info. Services, Trout Unlimited) <br />Objector Response -The applicant does not plan to expose groundwater; therefore, there <br />should be no groundwater lost to evaporation. <br />16. "How does the applicant propose to ensure that process waters released into the pits meet all <br />applicable water quality standazds, including those designed to protect surface flows that aze <br />likely hydro logically connected to the ground water impacted by the pits.?" <br />(Clean Water Action, Env. Info. Sen~ices, Trout Unlimited) <br />Response - There is no water quality standazd for the water for which the applicant proposes <br />to release into the gravel pit. The Division believes the process water (dust suppression <br />water) will be adequately filtered of suspended solids before it reaches any surface flow. The <br />water will percolate through a large volume of sand and gravel before it reaches ground <br />water . The ground water will then move through additional large volumes of sand and <br />gravel before it has a chance to reach surface flows. The water should be as free of <br />suspended solids as the rest of the natural ground water. <br />17. "What is the projected quality of the process water?" <br />(Clean Water Action, Env. Info. Services. Trout Unlimitec!) <br />Response -The applicant will obtain his water for dust suppression from the Arkansas River. <br />The water will have the same quality as the river waters until it is used for dust suppression. <br />Afrer use for dust supression, the water will be quite high in suspended solids, which will <br />be filtered out as it blows through sands and gravels before the water reaches off-site <br />locations. <br />Exhibit H -Wildlife Information <br />"What will be the impacts to local aquatic life?" <br />
