HSGs based largely on information procured from the NRCS online Web Soil Survey. <br /> 4. General disturbed areas and roads CN based on combination of gravel and dirt roads and newly graded <br /> areas with no vegetation. <br /> 5. Waste rock CN based on engineering judgement and previous analyses. The extremely coarse gradation of <br /> the waste rock does not allow for application of an HSG. <br />
