~~~ Doc Date:12/11/2001 III IIIIIIIIIIIII III <br />• tSMALL AREA EXEMPTION <br />There are four small area exemptions located on the active New Horizon 2 mining <br />area. The surface runoff water from these sites can not be diverted into an approved <br />sediment pond for water treatment. Since these areas are small in nature, the flow <br />rates will be small and the water running off these small area exemptions will be treated <br />by one or a combination of :live grass filters, straw bale filters, silt fence or small <br />earthne berm evaporative basins. Listed below are the four permitted small area <br />exemptions. <br />Small Area Exemption #1: <br />• <br />U <br />Is located in the original permitted tract that is due west of Pond 007 by approximately <br />300 feet and consist of a small outslope from a topsoil pile "K" that is below grade of <br />Pond 007. The runoff from this area was modeled using Storm Version 6.21. The <br />water is controlled by a contour ditch with strawbale and grass lined ditches to treat the <br />water before leaving mine property. Below, you can examine the runoff calculations. <br />For locations, see Map 2.05.3-1. <br />(REVISED 12!00) <br />Attachment 2.05.3(3)-11-1 <br />
