<br />plans. <br />6.4.4 EXHIBIT D-Mining Plan <br />The mining plan is required to show the location of all water diversions and impoundments used <br />in support of the mining operation. Since both the eristine pond and the proposed pond are <br />being used to provide sediment control for the minine operation, these structures must be <br />included in the pernrit and affected area. More detail about their construction and location will <br />be requested under Exhibit G. However, the mining plan maps will need to be revised to include <br />both ponds and water diversions used in the permit and affected areas. In addition, any roads <br />that will be used in conjunction with the mining operation must be included on the mining plan <br />map. <br />6.4.5 EXHIBIT E- Reclamation Plan <br />The topsoil appears to vary greatly in texture, depth ,occurrence etc.. and as a result, the <br />application is very vague with respect to the salvage, storage and reapplication plan. However, <br />proper topsoil salvage and replacement is key to successful reclamation. On page 10 it is stated <br />that the existing topsoil is very similar to what the material remaining after mining is completed <br />will be, however, even if the existing topsoil is very thin and of similaz texture, it contains a <br />significant amount of organic matter and other nutrients such as nitrogen, phosphorus, and <br />potassium that will not be present in the substratum. As a result, ALL available topsoil must be <br />salvaged, stockpiled and replaced over the regraded areas. According to the NRCS report, there <br />appears to be approximately 3-6 inches of topsoil available. In addition, the application commits <br />to salvaging 6 inches in areas where there are noxious weeds present. Based on the pre- <br />operational inspection that was conducted on May 25, 1999, there will be places where little to <br />no topsoil is available, however, there are also several areas where more than 6 inches will be <br />found. As a result of this variability, the operator should simply commit to salvaging all <br />available topsoil and replacing a minimum of 3 to 6 inches. For bonding purposes, replacement <br />of 6 inches will be used. The following sections need to be addressed in appropriate detail as <br />follows: <br />(2)(d) Please provide a detailed description of how much topsoil will be removed, where it will <br />be stockpiled and measures that will be taken to protect the topsoil during storage such as <br />upland diversions and temporary seed mixes. Since there are numerous phases, a typical <br />diagram can be used to illustrate the general concept that will be used for all phases. In <br />addition, please provide a description of how the spoil will be regraded, stabilized, and <br />compacted and what measures, such as ripping or roughening of the spoil/soil contact. <br />will be taken to ensure that slippage zones between regraded spoil and topsoil will be <br />eliminated. <br />With respect to the revegetation plan, clearly the post-mining land use of <br />rangeland/pasture land precludes the use of woody plant species on the two relatively flat <br />2 <br />
