• <br /> <br />Page l4 <br />at 50 years." <br />(M. Brown, J. Brown) <br />Response - (See Response for 3.) <br />]0. "If the high sediment wash water is dumped into the applicant's gravel pi[, added turbidity in my <br />spring will be caused by the gravel pit operation." <br />(R. Steers, M. Brown, J. Brown) <br />Response -The applicant does not plan to wash the gravel. The intent is to suppress dust with water <br />that will flow to a gravel pit. The water will be well-Filtered before it leaves the permit area. The <br />filtering will come from the sand and gravel under the gravel mining area. The water will be <br />additionally filtered by the alluvial sands and gravels which it will flow through as it moves away from <br />the permit area in the groundwater system. <br />I1. "The hydrology information submitted to the Division is not correct according to our current <br />research." <br />(S. Steers) <br />Response -The individual submitting this comment did not specify how the hydrology information <br />submitted by the operator was incorrect nor was the Division provided with a copy of the research for <br />review. <br />12. "It does not appear at the present time that the applicant has provided the required baseline studies of <br />surface and ground water acid mine production analysis (if pyrite is present) and operational and <br />reclamation features that will protect surface and ground waters from pollution." <br />(Clean Water Action, Env. /nfo. Services, Trout Unlimited) <br />Response -Rule 6.4.7 of the Construction Materials Rules and Regulations does not require the <br />operator to provide baseline studies of "surface and ground water acid mine production". The <br />Division has no reason to believe that there is any significant potential for acid production by the <br />proposed operation. <br />l3. "Another important concern regards the potential for the local clay to release phosphorus (primarily <br />via sediments) to the Arkansas River system." <br />(Clean WaterActiort, Env. Info. Services, Trout Unlimited) <br />Response -The proposed operation will not be mining clay materials or removing clay-bearing <br />overburden. The applicant's sediment control plan is adequate. <br />
