Exhibit L — Reclamation Costs <br />Soil Demand AND Re- soiling of Affected Lands (refer to Exhibit D): <br />NOTE: The soil demand (and related costs) will decrease proportionately as extraction <br />activities increase over each Tract of planned extraction. For now, an area estimate of <br />12.21± acres (Refer to Exhibit D) will be determined for resoiling expenses. At a depth <br />of 0.5± feet, the total volume = 12.21± acres x 0.5± feet of soil replacement x <br />43,560.0± sq.ft. /acre = 27 cu.ft. /cu.yd. = 9849.40± cu.yds. total soil requirement. <br />The majority of soil placement can occur using the an average placement distance of <br />600 ft., or less along embankments, (utilizing the same assumptions utilized at either <br />Kurtz or Heintzelman Projects as shown at the back of this exhibit). <br />9,849.4± cu.yds of soil demand <br />x $ 0.843 per LCY. <br />$ 8,303.04 to replace 0.5± feet of soil over the existing affected lands remaining above <br />the anticipated final water level. <br />Establishment of Vegetation over Affected Lands: <br />The demand establishment of vegetation over the affected lands will also diminish <br />proportionately with the planned extraction of the Tracts. For now, the total exposure <br />is estimated as indicated above to be 34.23± acres under a default: <br />NOTE: The vegetation demand (and related costs) will decrease proportionately as <br />extraction activities increase over each Tract of planned extraction. The cost for seed is <br />shown on Exhibit L - Table L -1: Primary/Preferred Re- vegetation Seed Mixture and <br />Costs and Exhibit L - Table L -2: Optional /Default Re- vegetation Seed Mixture and <br />Costs. The mixture includes a substitute for mulch in the inclusion of a wheatgrass <br />hybrid. The Division has historically agreed with and approved the inclusion of this <br />hybrid as a substitute for mulch. These costs are as follows: <br />$ 77.00± Preferred Seed Mix <br />x 34.23± acres <br />$ 2,635.71± Sub -Total Seed <br />The cost for applying seed is based upon information derived in proximity to the <br />Northern Colorado economy. Costs for tilling, fertilizing and seeding are based upon <br />estimates from Longs Peak Equipment Co. These costs, including labor, are reflected <br />as follows: <br />$ 25.00± per acre Tilling <br />$ 20.00± per acre Fertilizing <br />$ 20.00± per acre Seeding <br />$ 65.00± per acre Total Application Cost per Acre. <br />Varra Companies, Inc.
