A map depicting the various physical boundaries of the facilities outlined above is included with <br />the reclamation cost estimate. The reclamation summary table addresses each of the facilities <br />and related cost items. The cost summary table, back -up tables, and engineering calculations and <br />assumptions to develop the cost information are part of a spreadsheet model developed for <br />CC &V by Ellis Environmental Engineering, Inc. ( "EEE ") and updated/modified by Steffens and <br />Associates, Inc. ( "Steffens "). It should be noted that acreages depicted for the various facilities <br />as part of hte financial warrenty calculations may not match the disturbance areas provided <br />elsewhere due to the following reasons: (1) the reclamation cost estimate takes a "holistic" view <br />of the boundaries between facilities where the final reclamation demarcation lines are not <br />definite but rather blend from one area to another and (2) reclamation grading, slope reduction, <br />and contouring oftentimes results in a facility encroaching outside its development footprint, <br />resulting in a slightly larger affected area for reclamation. <br />The general approach for cost estimating involved calculating the areas and volumes for <br />particular facilities using either direct measurements from ACAD drawings, constructing cross - <br />sections before and after reclamation, measuring from aerial photos using a polar planimeter, or <br />simple computations involving lengths, widths, and heights. Using the volumes and areas <br />determined as above, earthmoving and reclamation equipment were selected based on <br />productivities developed for the specific project involved utilizing such resources as the <br />Caterpillar Performance Handbook, time study information from EEE files, and engineering <br />judgment, where appropriate. <br />For most facilities the basic outline of reclamation involves the following sequential steps: (1) <br />grading, slope reduction, re- contouring with dozers or scrapers; (2) replacing growth medium to <br />a depth of approximately six inches; (3) preparing a seed -bed by scarifying or ripping; (4) <br />revegetation consisting of fertilizing, seeding, and mulching; and (5) planting trees and shrubs on <br />north- and east - facing slopes. Certain deviations from this basic approach exist for facilities <br />such as building footprints where only minor grading and "touch -up" will be required once <br />demolition has taken place. Other facilities, such as the approximate 2H:1V slopes of the Main <br />Cresson Mine area backfilled portion, will require special treatment — helicopter seeding due to <br />the marginal accessibility for conventional reclamation equipment. <br />CC &V is considering submitting periodic financial warranty updates to the OMLR and <br />incrementally bonding for disturbances for each year as well as the unreleased portions of <br />disturbance from previous years. This is consistent with the incremental bonding approach <br />previously utilized by CC &V and accepted by the OMLR, and consistent with the Mined Land <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />13 -2 <br />
