Public Lands and other easements and Right-of-Ways are offset from <br /> operations and while they may fall within the 409.234± acre parcel — are excepted from <br /> the permit conditions to the extent of their approved setbacks. <br /> The following estimates utilize assumptions based upon the pre-disturbed state of the <br /> application for purposes of determining estimated costs of reclamation and correlated <br /> financial warranty. Where appropriate, information is generalized and approximated <br /> from similar estimates determined by the Colorado Office of Mined Land Reclamation <br /> (OMLR), as indicated: <br /> RECLAMATION EXPOSURE: <br /> Based upon the Extraction and Reclamation Plans of this application, the status and trend <br /> of activities and affected land; and related calculations to estimate reclamation liability, <br /> are determined as follows. <br /> Please Note: Due to the difficulty of calculating heavy equipment costs similar to the <br /> Division's software program, unit costs from previous and reasonably current Division <br /> estimates of like or similar kind have been utilized to create a reasonably close estimate. <br /> The per unit basis from Division records are shown along with other sources used or <br /> referenced to determine unit costs, at the back of this exhibit. <br /> METHOD OF EXTRACTION: <br /> Before concurrent grading, resoiling, and revegetation for reclamation can commence, a <br /> perimeter keyway must first circumnavigate the area where the perimeter slopes form <br /> along the extraction limits. For Two Rivers, this includes four sequential areas of <br /> extraction: <br /> • 127.10±Acres - Central Field — Center Section <br /> 23.19± Acres - Central Field — North-East Section <br /> • 30.47± Acres - Central Field - West Section <br /> • 53.30± Acres - North-West Field <br /> Exhibit L: Financial Warranty Map, shows Initial Extraction will begin in the yellow hatch <br /> area shown on the Exhibit L Map, comprising 16.26±.
