Estimate of Actual Cost of Reclamation The Division estimated the cost [o reclaim the White Banks Mine based on the anticipated worst case disturbance and the approved reclamation plan. The Division estimates a cost of $l 1,500.00. Please note that the bond was calculated on the seed mixture proposed by the applicant, and approved by the landowner (US Forest Service). A copy of the Forest Service letter is attached. Therefore, the Division estimated a cost for transplanting only shrubs and not trees. A cost for transplanting tublings and a fertilizer pellet were included in the estimate. The specified number of shrubs will need to be established on the reclaimed site in order for the bond to be released in its entirety. 3. Please be aware that the Division does not include a cost for inflation in the bond estimate because it is not mandated by the Colorado Mined Land Reclamation Act of C.R.S. 34-32-101. However C.R.S. 34-32-117(4)((b)(I) states that in any single year during the life of a permit, the amount of required financial warranties shall not exceed the estimated cost of fully reclaiming all lands to be affected. In addition, C.R.S. 34-32-I l7(4)(c)(i) states that the Board may from time to time for good cause shown, increase or decrease the amount and duration of required financial warranties to ensure the financial warranty is adequate to achieve the approved reclamation plan. The adequacy of the financial warranty is reviewed during the routine inspections conducted by the Division.
