Depths vary by field from approx. 30 to 45 <br /> feet. Depths are shallower as the adjacent hillside rises to the north; while <br /> the deposit dips deeper toward the South-East of each designated Field. <br /> Soil Salvage: Resource recovery will commence by first removing the upper <br /> [A profile/plow layer] six to twelve inches of soil [six (6.0±) inches typical], <br /> combined with existing grass or crop stubble. Removal will utilize scrapers or <br /> excavators, aided by dozers where necessary, and hauled to the Northeast <br /> Section of Central Field. All extraction and surface related activities detailed <br /> in this application will occur under an approved Fugitive Dust Permit issued <br /> by the Colorado Department of Public Health and Environment (CDPHE). <br /> Until resoiling activity occurs, where harvested soils have been stockpiled and <br /> remain undisturbed for reclamation or sale, they will be seeded with the <br /> mixture specified under Exhibit L - Table L-1: Primary/Preferred Revegetation <br /> Seed Mixture. A stabilizing cover of native vegetation may take up to three <br /> years to fully establish the desired cover. In the event the native seed mixture <br /> fails, an optional mixture of predominantly introduced species will be used as <br /> a fall back to better assure a stabilizing cover of vegetation.
