(GSB) is providing Technical Revision JR) which is a notice of intent to <br /> backfill inert structural fill, generated outside of the permit area at the Apache Mine per rule 3.1.5.9. <br /> We have enclosed a check for the TR fee of $216. <br /> Placement of the scrap brick and scrap block will assist in site reclamation by providing additional fill <br /> material as replacement for mined materials. <br /> The inert fill material will consist of scrap brick and scrap block generated from the GSB's Denver <br /> brick plant and Colorado Springs Block Plant respectively. We anticipate placing 50,000 tons of <br /> scrap brick and block into the mine pits. An affidavit is attached certifying that the scrap brick and <br /> scrap block mix is inert and "clean". <br /> We plan on hauling the scrap brick and scrap block and placing it on the clay stockpile pad areas <br /> and/or mine pits (inside the current disturbance boundary). Then when concurrent reclamation <br /> begins approximately in 2016 we will place the scrap brick and scrap block into the pit. We do not <br /> anticipate any settling and voids due to the placement of these materials because the materials will <br /> be placed in 5-10 foot lifts, blended with the current overburden materials and compacted. The scrap <br /> brick and scrap block will be hauled starting on or about September 29, 2014 and ending September <br /> 29, 2024. <br /> These materials will not impact surface water runoff quality, because these materials does not contain <br /> contaminants, and local area storm water runoff is diverted away from the mine disturbed area. The <br /> scrap brick and scrap block will not contaminate ground water because it has been fired to a high <br /> temperature. Further, these materials will not be placed below the saturated zone. <br /> Please feel free to contact me with any questions at 303-783-3058. <br /> Sincerely, <br /> General Shale Brick, Inc. <br /> b%r <br /> ason E.
