Exhibit L - Reclamation Costs Since there is some swell, the volume of stockpiled soil is multiplied by a swell fact or 1.33 to this effect: 18,214.54± cu.yds of soil demand x $0.413 per L.cu.yd. $ 7,522.61 to replace 0.5± feet of soil over the existing affected lands remaining above the anticipated final water level. Establishment of Vegetation over Affected Lands: The demand establishment of vegetation over the affected lands will also diminish proportionately with the planned extraction of the Tracts. For now, the total exposure is estimated as indicated above to be 22.57± acres under a default: NOTE: The vegetation demand (and related costs) will decrease proportionately as extraction activities increase over each Tract of planned extraction. The cost for seed is shown on Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture and Costs and Exhibit L - Table L-2: Optional/Default Revegetation Seed Mixture and Costs. The mixture includes a substitute for mulch in the inclusion of a wheatgrass hybrid. The Division has historically agreed with and approved the inclusion of this hybrid as a substitute for mulch. These costs are as follows: $ 27.80± Dry Land Mix $ 27.50± Hybrid Mix $ 55.30± Total The cost for applying seed is based upon information derived in proximity to the Northern Colorado economy. Costs for tilling, fertilizing and seeding are shown in Exhibit L - Addendum D: Longs Peak Equipment Co. estimate. These costs, including labor, are reflected as follows: $ 25.00± per acre Tilling $ 20.00± per acre Fertilizing $ 20.00± per acre Seeding $ 65.00± per acre Total Application Cost. Total reseeding expense = $ 120.30/acre. .•. $120.30±/acres x 22.57± acres = $ 2,715.18± Sub-Total reseeding costs. Assume a 50± percent failure and add half the expense back into the total, or: $ 2,715.18± Sub-Total reseeding costs Varra Companies, Inc.
