UNITED STATES DEPARTMENT OF AGRICULTURE <br />SOIL CONSERVATION SERVICE <br />November 1, 1985 <br />Mr. Lloyd Barnhart <br />3 Sedum Court <br />Pueblo, CO 81001 <br />Dear Buck: <br />• This is in reference to a site investigation done October 24, <br />posed clay mine located in the SW 1/4, section 1, T25S, R65W, <br />information may be used by your company to fulfill [he requi~ <br />Colorado Mined Land Reclamation Board. <br />1985 on a pro- <br />The following <br />;ments of the <br />The pre- and post-mining land use is rangeland, it is not pr a farmland, <br />and there should not be any groundwater problems encountered during mining. <br />The owner of the land is Lewis E. Edmondson. Ed Johnson (re ained by Summit <br />PYessed Brick 6 Tile Co.) will be responsible for the reclam lion. <br />The area proposed far mining is outlined on the attached sot survey map. <br />The area is mapped as Travessilla sandy loam, Clay deposit are found <br />b_2ow an overburden of Dakota Sandstone. The suitability of ravessilla for <br />topsoil is rated poor due to the layer being thin. <br />The Travessilla soils support a plant community dominated by blue grama with <br />significant amounts of red threeawn, sideoats P,rama, ring mu ly, and <br />New Mexico feathergrass. Western wheatgrass appears in areas where topsoil <br />depth increases, whereas New Mexico feathergrass appears in yeas where <br />topsoil depth decreases. A list of the existing vegetation nd specific <br />cover estimates are provided on the attached CO-ECS-2. <br />The Soil Conservation Service recommends the following steps to stabilize <br />the site after mining: <br />1) Prior co mining, all topsoil which can be reasonably rem ved should be <br />• stockpiled. Since outcrops of sandstone occur throughout th proposed <br />mining area, topsoil collection sliuuld be selective. <br />2) Prior to spreading the topsoil, the area should be banks oped so that <br />no slope exceeds 3:1 slope. F.ough areas should be smoothed o permit <br />easier seeding and mulching. The area should be scarified, 'f practical, <br />to a depth of 6 inches to permit better bonding between the topsoil and the <br />underlying soil material. After scarification, the topsoil s ould be uni- <br />formly spread over the area. <br />0 <br />
