over 54 acres of disturbance. In regards to the Tie-Across Haul Road, <br /> approximately 9 inches of topsoil will be spread of this disturbed area. <br /> Three soil mapping units were identified during a Soil Conservation Service <br /> survey. They consist of Spicerton variant, an unnamed soil type occurring along <br /> the first terrace of Dry Creek, and Morapos soil types. The Spicerton variant soil <br /> exhibits elevated SAR values below 1-inch depth and high EC levels below 8 <br /> inches. The Spicerton variant soils are not recommended for topsoil salvage. The <br /> Morapos soils (7C) and the unnamed soil mapping unit(5AI)have loamy to silty <br /> clay loam textures and no limiting characteristics in the surface horizons. The <br /> Morapos soil is salvageable from 0-to 9- inch depths while the unnamed soil is <br /> suitable for topsoil salvage from 0 to 24 inches. An addition soil mapping unit, an <br /> additional Morapos soil type (713), is identified for TAHR soil salvage. <br /> Topsoil replacement occurred once facilities were dismantled and the land re- <br /> contoured to blend with the surrounding topography in 2011. DRMS verified <br /> topsoil replacement thickness during an April 26, 2012 inspection. Seven holes <br /> were hand dug with a shovel on the topsoiled area. This area was found to have a <br /> mean topsoil replacement thickness of 14.5 inches. Topsoil replacement <br /> thickness of 6 to 9 inches is approved in the PAP. <br /> The sediments ponds will remain as permanent structures,the rail loop has had all <br /> rail ties removed and will be transferred to the town the town of Hayden as <br /> recreational use. Structures that will remain following reclamation include Routt <br /> County Road 37,the sediment ponds, topsoil piles associated with the rail loop <br /> and ponds, and rail loop ballast. <br /> No specific approvals are being granted concerning topsoil removal, storage and <br /> redistribution. <br /> V. Sealing of Drilled Holes and Underground Openings <br /> Sealing of wells, holes, and other openings is discussed in Tab 23,Attachment 23-3 of the <br /> PAP. <br /> HGL sealed wells 22772-F, HGDAL1, and HGDAL2 in 2007. Well abandonment reports <br /> were submitted to the Division by HGL in November 2007. HG Shallow Well No. 1 was <br /> sealed in November 2011. The well abandonment reports are located in Appendix 7-14 of <br /> Tab 07. <br /> A. The Division will require that each hole,well, or other underground opening be capped, <br /> sealed, backfilled, or otherwise properly managed(4.07.3). <br /> VI. Use of Explosives <br /> No specific approvals are granted to the applicant under this section. <br /> 24 <br />
