and suitability of stockpile material. Results of this inventory are located in <br /> Attachment 9- 1 of the permit. Approximately 55, 100 cubic yards of soil material <br /> have been stockpiled. Analyses of the stockpiled material indicate elevated SAR and <br /> increased salinity levels at lower depths of topsoil piles # 1 and #3. Due to these <br /> factors, somewhat less than the 55, 100 cubic yards of the stockpiled topsoil material <br /> will be redistributed on disturbed areas during reclamation of the facilities area. This <br /> volume will allow for replacement depths of 6 to 9 inches over 54 acres of <br /> disturbance. In regards to the Tie -Across Haul Road, approximately 9 inches of <br /> 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 the <br /> 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 thickness <br /> of 6 to 9 inches is approved in the PAP. <br /> The rail loop, sediment ponds, and TAHR have not been reclaimed at the time of <br /> this writing. Structures that will remain following reclamation include Routt <br /> County Road 37 and US Highway 40. The right-of-ways along these roads account <br /> for 3. 3 acres and will not be topsoiled. <br /> No specific approvals are being granted concerning topsoil removal, storage and <br /> redistribution. <br /> V. Sealing of Drilled Holes and Underground Openings Rule 4.07 <br /> Sealing of wells, holes, and other openings is discussed in Tab 23, Attachment 23- 3 of <br /> the PAP. <br /> HGT sealed wells 22772-F, HGDALI, and HGDAL2 in 2007. Well abandonment <br /> reports were submitted to the Division by HGT in November 2007. HG Shallow Well <br /> No. I was sealed in November 2011. The well abandonment reports are located in <br /> Appendix 7- 14 of Tab 07. <br /> 23 <br />
