We will use the seed mix that was included in the 1998 110 permit. That seed mix is, by the way, based on 30 years of experience and involvement in high-altitude revegetation. The mix is as follows: Seed Mix P L "` Alpine Timothy Ph/eum a/pinum and/or Alpine Bluegrass Poa alpina and/or Spike Trisetum Trisetum spicatum all totaling 4 Tufted Hairgrass Deschampsia caespitosa 3 Timothy Ph/eum pratense 4 Kentucky Bluegrass Poa pratensis 3 Hard Fescue Festuca ovina Durar 4 Sheep Fescue Festuca ovina Covar 4 Red Fescue Festuca rubra 5 Red Top Agrostis alba 5 White Dutch Clover Trifolium repens ~ Total 37 `PLS is pounds of pure live seed per acre. We have committed to leaving (or placing) a 1 to 2 foot high berm of dredge tailing along the down~radient edge of the affected land as the operation enlarges. Most, 'rf not all, precipitation will infiltrate the dredge tailing because it is so permeable. Still, the objective of the berm is to filter any potential surface runoff that might occur in a major precipitation event. You have suggested that we plant willows in the berm. We believe that also is a good idea and agree to plant willow cuttings in the base of the berm and to leave the berm as asemi-permanent feature in the reclaimed topography. We will plant approximately 1 cutting every 5-feet -- but -- as with the other aspects of revegetation (and for the same reasons) we do not expect to be held to any standard or success rate for these cuttings. The willow cuttings will be obtained from the willows adjacent to the affected land. It is estimated that one-half of the edge of the affected land will be bermed. Therefore, approximately 1,000 cuttings will be required. You have suggested that the final grading of the site should provide a natural appearance with undulations. We will endeavor to do that but the degree of undulation that we can leave will be quite limited because we intend to remove essentially all of the dredge tailing down to 1.5 to 2.0-feet above the water table. Hence, we cannot leave extensive undulations in the surface because we cannot get closer than 1.5-feet to the water table. 2. Fuel Storage 2
