in Attachment 9 -1 of the permit. Approximately 5 5, 100 cubic yards of soil <br />material have been stockpiled. Analyses of the stockpiled material indicate <br />elevated SAR and increased salinity levels at lower depths of topsoil piles 91 and <br />#3. Due to these factors, somewhat less than the 5 5, 100 cubic yards of the <br />stockpiles topsoil material will be redistributed on disturbed areas during <br />reclamation of the facilities area. This volume will allow for replacement depths <br />of 6 to 9 inches over 54 acres of disturbance. In regards to the Tie - Across Haul <br />Road, 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 office trailer area, parking area and driveway, rail loop, sediment ponds and <br />TAHR have not been reclaimed at the time of this writing. Structures that will <br />remain following reclamation include Routt County Road 37 and US Highway 40. <br />The right -of -ways along these roads account for 3.3 acres and will not be <br />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 the <br />permit application. <br />HGT sealed wells 22772 -F, HGDALI, and HGDAL2 in 2007. Well abandonment reports <br />were submitted to the Division by HGT 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 />Hayden Gulch 28 February 11, 2014 <br />
