Ms. Candace Thompson <br /> July 25, 1985 <br /> Page two <br /> 3 . See attached map (Enclosure 1) for the approximate <br /> location of the holes. <br /> 4 . Topsoil salvage and replacement - It is not <br /> planned to remove the vegetation or salvage topsoil unless <br /> absolutely necessary. From the road that is adjacent to the <br /> site, the vehicle on which the small rotary drill is mounted will <br /> drive through the aspen grove to the drill sites. The vehicle <br /> need not retrace its route through the grove and should have <br /> minimal adverse impact on the heavy grass growing among the aspen <br /> trees. A few of the smaller aspen trees will be cut down to <br /> allow the vehicle to wind around through the larger trees. <br /> 5 . Drilling method to be used - For measuring the <br /> depth of the alluvium that overlies the bedrock; a small truck <br /> mounted 2" to 4" rotary drill will be utilized. <br /> 6 . Disturbance at a drill site - It should be minimal. <br /> To the extent possible, the drill rig will traverse the existing <br /> land surface without disturbance. The cuttings will temporarily <br /> cover 2 or 3 square yards. Excess cuttings will be removed to a <br /> nearby shale slide area. <br /> 7 . Reclamation plan and revegetation seed mix for <br /> disturbed areas - If any areas are disturbed to the extent that <br /> the vegetation has been destroyed they will be seeded and mulched <br /> immediately following the drilling. The following seed mixture <br /> will be utilized: <br /> Grasses Seeding Rate <br /> Redtop 1/2 <br /> Kentucky Bluegrass (Troy) 1-1/2 <br /> Canada Bluegrass (nubbins) 1-1/2 <br /> Timothy 1-1/2 <br /> Creeping Meadow Foxtail 4 <br /> Smooth Brome (Manchar) 6 <br /> Hard Fescue (Durar) 4 <br /> Red Fescue 4 <br /> Forbs <br /> Cicer Milkvetch 1 <br /> Dutch Clover 1 <br /> Alsike Clover 1 <br /> Lewis Flax 1 <br /> TOTAL 27 lbs/acre <br />
