FkUrl FHX NU. y1b464111i1 Jun. 14 L~Ei4 bd:2tg-1M F'S 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 revegetatl0n. The mlx ~ as follows; Seed Mix L Alpine Timothy Ph/eum alpinum and/or Alpine Bluegrass Poe alpine andlor Spike Trisetum Tnsetum spicatum all totaling 4 Tufted Hairgrass Deschampsia caespitosa 3 Timothy Phieurtt pralense 4 Kerrtudry Bluegr~,s Poe,wetensis 3 Hard FPCntP l=r~rca avina Cturar 4 Sheep Feswe Festuca ovine Cover 4 Red Fescue Festuca rubs 5 Hed I ap Ag~osUS albs 5 Wttile Dulrit Cluver Trrlolium repe0s ~ ToFal 37 'PLS is pounds of pure live seed per acre. We have committed to leaving (or p(acing) a 1 to 2 foot high berm of dredge tailing along the down.gradient edge of the affected land as the operation enlarges. Most, tf not all. predphatlon wlll Inflllrate the dredge tailiru~ because it is so permeable. Still, the objective of the berm is to filter any potential surface Nnoff that aught oaair in a major precipibtion 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 baee of the berm and to leave the berm as a seml-permanent fearure in the reclaimed topoq~~ph~ We will plant approximately 1 cutting every 5-feet - bul - as with the ot(isr aspects of revegetation (and for the same reasons) we do not expel t0 be held to any standard or success rate for rhese rxrTrings. The willow cuttings will be obtained from the wtllows adjacent to the affected land. R is estimated that one-half of the edge of the atFe~:ted land will be benned. Therefore, approximately 1,000 cutiings will be reyufred. You have sugge.~ that the final grading pf the sde shoultl provide a natural appearance with undulations. We will endeavor to do that but the degree of undulation that we can leave will be quits limited because we (mend i0 remove essentlally all Of the dredge talling down ro 1.5 m 9.0-feet above the water table. I lence, we cannot leave extensive undulations in the surface because we cannot get loser than 1.5-feet to the water table. 2. Fuel Storage
