Slurry Wall Design Report <br /> Loloff Pit <br /> 5/24/2016 <br /> Page 4 of 16 <br /> is applied to the water entering the test zone and maintained for a specified time. Water loss <br /> into the test zone is then recorded and permeability is calculated. <br /> 2.2 Previous Investigations <br /> In May 2014, Soilogic, Inc. conducted a geotechnical subsurface investigation at the Sorin <br /> Useful Aggregates property in Weld County. This property is located to the east of the Loloff Pit <br /> and is the potential source of supplemental fines to be used on the project. The investigation <br /> encountered lean clay with silt and sand from approximately 2 to 7 feet below ground surface <br /> (bgs), sand with gravel from 10 to 17 ft bgs, lean clay and clayey sand with gravel from 30 to 42 <br /> feet bgs, sand and gravel with cobbles from 100 to 124 feet bgs and claystone as deep as 125 <br /> feet bgs. Groundwater was encountered at depths ranging from 40 to 51 feet bgs. <br /> In August 2013 J&T Consulting, Inc produced a technical revision request to the State of <br /> Colorado for the Loloff Mine which included a mining plan, water information, permanent <br /> manmade structures, geotechnical stability exhibit, hydrology, and slope stability analyses. <br /> In February 1981, Empire Laboratories, Inc conducted a mineral evaluation at Loloff pit which <br /> consisted of nine test borings. Soil conditions included silty topsoil and fill material, sandy silty <br /> clay, sandy silt, sand and gravel, and sandstone/siltstone bedrock. Bedrock was encountered at <br /> 41 to 46 feet bgs. Groundwater was encountered at depths ranging from 3 to 15 feet bgs. <br /> The site is an active mining operation of sand and gravel. Several documents exist for mine <br /> permit no.
