P1r. Frank M. Graham, Jr. <br />January 13, 1982 <br />Page -9- <br />2. Considering the size and log term impLCt of this Site, I sent a copy <br />of this application to the Di vision of Wildlife for their further review <br />and cormnent. I will send yov a copy of their evaluation when I receive it. <br />Exhibit I <br />1. Considering the variabilityof such a large site, I feel that more on-site <br />soils data are needed. The logs of test holes drilled on the site show a full <br />foot of topsoil at all locations drilled. Yet only 5" is to be saved for <br />reclamation. Nas any more detailed on-site soil investigation been done? <br />2. Are the vegetation recommends`ions of the Soil Conservation Service based <br />on on-site inspection or the general information given in this exhibit? <br />3. The permit area should be outlined on the soils map to facilitate an <br />examination of how soil types vary over the site. <br />4. Does the general information given include all soil types in the permit <br />area (e. g., including those found in drainages)? In this regard, are there <br />areas of deeper soils that would be useful in reclamation? <br />'~ Exhibit J <br />1. Xow does the vegetation list given vary over the affected land? Considering <br />the size of the area and the presence of drainages, deep overburden areas, varying <br />slope aspects, etc., I would expect some variation within the affected land. <br />This would have some affect on the revegetation plans. <br />2. What tree species are present on the site, and where are they located? <br />3. I suggest the addition of a legume appropriate to the agricultural end <br />use to the revegetation seeding mixes. My preliminary suggestion is either <br />Cicer milkvetch or Yellow sweetclover at a drilled rate of 0.5 to 1.0 lb PLS/acre; <br />or you may consult with the Soil Conservation Service for an appropriate legume. <br />Exhibit L <br />1. If no major grading is necessary, I would, in general, concur with your <br />cost estimates for a typical 90-acre section of the permit area. I do have <br />some reseryarions, however. They are as follows; <br />a. Will only 5" of topsoil be replaced? More seems to be available, <br />and 5" may not be enough to assure reclamation. If all topsoil is <br />replaced, the reclamation costs could go up considerably. <br />b. The costs for the reconstruction of stream channels (in those areas <br />where they are present) could also raise reclamation costs. These costs <br />should, in some way be considered. <br />c. Necessary grading for reclamation may include more than fine grading <br />in a worst case situation. Please clarify this matter. <br />2. The maximum affected acreage at any one time must be bonded. This includes <br />all areas within the boundaries of the permit area that are somehow part of the <br />mining operation. It is obvious €rom your description of the gravel resource that <br />
