<br /> <br />Ms. Margaret Koperski <br />June 22, 1978 <br />Page 2 <br />to remove material from time to time. We will do this. <br />Maximum height of the cut is approximately 16 feet and <br />length about 400 feet. Approximate area involved is 0.2 <br />acres. Again in our opinion, long-range reclamation would <br />be better served by maintaining an open cut. <br />The rail loadout loop cut designated 80-1-004 lies on <br />the northwest section on both sides of the track bed just as <br />it enters the second curve. Slope is 1.5 to 1.0. Soil type <br />is Lewis shale mixed with some clay at the base of the cut. <br />The clay probably derives from the shale or has not yet <br />consolidated. The shale surface gradually disintegrates <br />on contact with the atmosphere. If necessary, spalled <br />material will be removed from time to time during normal <br />ditch maintainance. Maximum height of the cut is 40 feet, <br />total length about 2300 feet; slope about 2:1; total area <br />(both sides of the cut) about 4.4 acres. This type subsoil <br />base is difficult to reclaim and revegetate. We wish to <br />maintain this in its present open condition. <br />The topsoil in the loop area to be used for redistri- <br />bution is alkaline with pH ranging from 7.2 - 7.8. In <br />reality, this area is a salt flat largely taken over by <br />grease wood and salt grass where some moisture is available. <br />Dry Creek and Stokes Gulch which cross the area already show <br />salt deposits creeping up the stream banks. <br />The topsoil from the area has been stored in piles and <br />will be revegetated with a mixture of yellow sweet clover - <br />0.7#/A; streambank (Sodar) wheatgrass 2.2#/A Western Wheat- <br />grass - 3.2#/A; Crested wheatgrass (NOrdan) - 4#/A seeds <br />which are salt tolerant. <br />This mixture will also be used for the other disturbed <br />areas. <br />All of the ridges along the top of each cut will be <br />provided with a drainage ditch to prevent erosion by preci- <br />pitation coming down the face of the cuts. The ditches in <br />the rail loadout will be directed to a sediment pond. The <br />sediment pond has been designed to prevent discharge except <br />for 25 year, 24 hour flood. <br />
