RECEIVED <br /> ROCK L& SEP 0 6 2119 <br /> Spec aggregates DIVISION OF RECLAMATION <br /> 1850 E. 1st. street, Craig, CO 81625 MINING AND SAFETY <br /> Phone & Fax (970) 824-2709 <br /> WagnerCorpColo@aol.com <br /> 2019' Inspection of Wagner Rock Pit <br /> M1999-018 Financial Warrantee Increase Objection <br /> 08-28-19 <br /> Demolition of the scale house; <br /> Demolition of the scale house will not be necessary in its entirety. <br /> The scale house is a portable office trailer with exiting frame, axel and tires <br /> which can be simply connected to a vehicle and pulled away. <br /> The scale and scale house are leased to Wagner Rock and will remain the <br /> property of the Lease. <br /> Slope reduction; <br /> Upon further review of DRM&S estimates and calculations of backfill <br /> quantities and other costs relative to the new bond amount, and further <br /> conversation with Amy Yeldell, it appears that the division has calculated <br /> slope reduction time based on the ripping and excavation of inert basalt rock <br /> on the high wall to the South. To simplify this report we base our volumes <br /> from your estimates. However, the basalt rock has all been mined out of the <br /> high wall. The existing material that would be used to generate slope <br /> material would be the stockpiled material (not topsoil) immediately above <br /> the high wall which is in excess of 60,000 yards of loose yellow shale. We <br /> keep high quantities of yellow shale in stock for reclamation efforts as well <br /> as marketing the material as backfill or pit-run material for resale. <br /> To slope the high wall with this loose, uncompact material will take about <br /> 16,000 yards requiring less than 28% of the machine time to complete. <br /> Ripping will not be required. <br /> If the division looks to slope with the inert high wall material, 13,000 yards <br /> of existing decomposed shale can be used. As there are no further reserves <br /> of hard basalt rock, ripping will not be necessary to excavate the shale as it <br /> is very loose bank material. The division's calculation should be adjusted <br /> down to account for the ease of shale versus inert basalt. <br />
