6.4.12 EXHIBIT L — Reclamation Costs
(1) All information necessary to calculate the costs of reclamation must be submitted
and broken down into the various major phases of reclamation. The information
provided by the Operator/Applicant must be sufficient to calculate the cost of
reclamation that would be incurred by the state.
(2) The Office may request the Operator/Applicant to provide additional, reasonable
data to substantiate said Operator/Applicant's estimate of the cost of reclamation
for all Affected Lands.
SUMMARY
OVERVIEW:
Summary Status of Affected and Unaffected land as of this Amendment (Exhibit C-1:
Existing Conditions and Exhibit C-2: Extraction Plan Map). The excavation has, prior to this
technical revision, been separated into two distinct pits. While maintaining the reference to
separate Tracts A (West Basin) and B (East Basin), it is anticipated that this will become one
large open extraction area that will be converted to a single lined reservoir upon completion
of mining. For the purpose of reclamation costs, the excavation and subsequent regraded
and lined reservoir is summarized as one pit:
Table 1 - Primary Data on Area of Affected Lands and Reclaimed Features:
Entity Tracts A and B
Combined
Extraction Area 111.05± Acres
Finished Basin Area 98.61± Acres
Static Water Area (Elevation 4790 feet) 90.10± Acres
Area Above Static Water Level (Extraction Area - Static Water Area) 20.95± Acres
Basin Area Volume (cuff) 106,695,270±
Static Water Level Volume (cu.ft.) 69,367,019±
Static Water Level Volume (Gallons) 518,901,334±
NOTE Well: All lands within the 155.86± acre permit area are to be considered as
affected lands under C.R.S. 34-32.5-103(1)respective of this permit application and any
subsequent permit revisions or amendments to the permit as originally approved.
The following assumptions are based upon the pre-disturbed state of the application for
purposes of determining estimated costs of reclamation and correlated financial warranty.
Where appropriate, information is generalized and approximated from similar estimates
determined by the Colorado Office of Mined Land Reclamation (OMLR), as indicated:
