After the results of the site visit <br />and a follow up phone conversation by Mr. Keffelew, she has agreed that these tributaries do not <br />exist on the site. She has agreed to write afollow-up letter stating these facts. Please see attached <br />follow-up letter. <br />Item 3: Exhibit "D" Mining Plan. <br />A) At this time, it has not been decided whether we will use a clarifier or ponds to settle our wash <br />water fines. If ponds are used, they will be included in our stormwater plan to handle wash <br />water as well as on site stormwater. There could be as many as four ponds but will probably <br />work sufficiently with only three. These ponds may vary in size but should no[ be any larger <br />than 100' wide by 200' long. These ponds would start out at approximately 15' to 20' deep. <br />They would eventually be filled up with the sediments from the washing process and would <br />require very little fill to complete reclamation. If the clarifier were used, then only one pond <br />would be required to contain any stormwater from the site. The current plan shows that this <br />pond is approximately 400'x 700'. The location of the pond is a proposed location and may <br />change as necessary throughout the course of mining at this facility. <br />B) The depth of material to be removed at this site will vary throughout the site. The topsoil will <br />range from 0" to 6" in depth and overburden material varies from 0' to 5' in thickness and <br />will be removed and stockpiled for later use. The material that is to be mined as a useable <br />product is expected to be about 100' in depth from the top of [he original grade of the pit. <br />This may vary greatly depending on the contour of the floor once it has been reached. In our <br />current operations the bottom elevation vanes throughout the permitted area. <br />Item 4: Exhibit "E" Reclamation Plan. <br />Mine slopes will still be mined to a 1:1 slope; however, final reclamation will be done to 3:1 slope <br />for future use as recommended by the Division of Minerals & Geology. <br />Item 5: Exhibit "G" <br />There is an existing well on this site. It is not our intent to abandon this well, but it is not ]mown <br />at this time what the capabilities of this well are. If the existing well is capable of meeting our <br />needs and is permitted properly then it can be used. If not, we will leave this well as it is and <br />permit another well to meet our needs. This still will not affect the surrounding wells. <br />473-3100 • Fax <br />
