The applicant intends to maximally disturb only thirty (30) acres at any given time while <br /> simultaneously reclaiming the regraded area following this disturbance. The maximum <br /> disturbance area will include the ten-acre area where topsoil has been stripped in advance <br /> of the extraction and the 10-acre active extraction area. Also included in this maximally <br /> disturbed area will be the 10-acre regraded pit floor which will be ready to receive topsoil <br /> that will be stripped in advance of the mining. Once topsoil is replaced it will be graded <br /> and conditioned for seeding by the addition of manure followed by discing and firming up <br /> the seed bed. Seeding will then occur as described under (f)(ii) below. Other areas that <br /> will need to be bonded include the processing area,product stockpile and loadout area,and <br /> any necessary access/parking areas, etc. located in Unit A. <br /> (f) A description of each of the following: <br /> (i) Final grading - specify maximum anticipated slope gradient or expected <br /> ranges thereof; <br /> No highwalls are expected at the site and all slopes leading into the excavated site <br /> will be regraded to 4H:1V or flatter. The reclaimed pit floors will be re-graded to <br /> be nearly level (0-1%) d raining slightly to the northeast. Upon placement of <br /> topsoil, the area will be graded level, and 20 tons/acre of manure will be applied. <br /> This will be incorporated using a disc followed by culti-packing to firm up the seed <br /> bed. <br /> ii)Seeding-specify types,mixtures,quantities,and expected time(s)of seeding <br /> and planting; <br /> The following seed mix is representative of native vegetative cover on the site and <br /> will be used for all seeding applications including seeding topsoil stockpiles <br /> remaining in place for more than 180 days. This is the seeding rate for drill seeding <br /> and the rate will be doubled if broadcast seeding is utilized. <br /> Seeding will occur during the first favorable season after topsoil has been replaced, <br /> graded and conditioned. The ideal seeding season for this mix would occur during <br /> its dormant phase which would be after October 15 and prior to April 15. If soil <br /> has been placed and prepared outside of these favorable seeding windows, a cover <br /> crop of oats (in spring during the month of May) or sorghum (in summer June- <br /> August) will be used to provide erosion and weed control as well as providing a <br /> standing cover mulch prior to seeding with the permanent grass seed mix during <br /> the next dormant seeding window. In early spring seeding(March-April)oats may <br /> also be inter-seeded as a companion crop at a rate of 15-20 pounds per acre. <br /> If soil is prepared after the spring/summer growing season, thereby requiring <br /> dormant seeding (from October-March), straw mulch will be applied at 2 tons/acre <br /> and crimped in following seeding. <br /> CoProp LLC—Rodeo Dunes Mine Page 4 of 6 <br /> Construction Materials Regular Operation(112(c))Reclamation Permit Application Form <br />
