040 <br /> General Shale <br /> Building The American Dream® RECE1V <br /> E® <br /> July 17, 2020 JUL 2 2 <br /> 2020 <br /> DIWSIOIV OF <br /> Colorado Department of Natural Resources MININGAND S FET y <br /> Division of Reclamation, Mining and Safety <br /> 1313 Sherman Street, Room 215 <br /> Denver, Colorado 80203 <br /> Attention: Mr. Eric Scott <br /> Subject: Chieftain South Mine, Permit No. M-1981-148 <br /> Dear Mr. Scott: <br /> General Shale Brick, Inc. (GSB) is in receipt of your inspection report dated June 18, 2020. <br /> The report cited the following problem: <br /> "The operator shall provide a dust suppression plan for this site as a Technical Revision <br /> to the permit by the corrective action date July 20, 2020. The plan should detail measures <br /> to be taken by the permittee for specific areas within the permit, and apply to both periods <br /> of inactivity(such as currently), and to periods of active mining at the site. This plan should <br /> be implemented immediately upon approval by the Division. " <br /> Corrective Action: <br /> General Shale is submitting a technical revision to the permit for a dust abatement plan <br /> for periods of mining activity and inactivity. <br /> GSB is providing Technical Revision (TR) for the following: <br /> 1. Notice of backfill of inert structural fill for scrap brick called grog. <br /> 2. Dust abatement plan <br /> 3. Allowance of scrap brick for stabilization of overburden-interburden stockpiles <br /> Notice of backfill of inert structural fill <br /> Placement of the scrap brick, called grog, will assist in site reclamation by providing additional <br /> fill material as replacement for mined materials. <br /> The inert fill material will consist of grog generated from the GSB's Denver brick plant. We <br /> anticipate placing 20,000 tons of grog into the pit. An affidavit is attached certifying that the <br /> grog is inert and"clean". <br /> We plan on hauling the grog to the mine and placing it on the clay stockpile pad areas as a <br /> possible dust suppressant if liquid dust suppressants are not cost-effective solution. When the <br /> grog breaks down and becomes dusty the grog will be picked up and hauled to the south end of <br /> General Shale, 1845 West Dartmouth Avenue,Denver Colorado 80110 Page 1 of 5 <br /> T: 1-800-477-9002 1 F: 1-303-781-1818 1 www.generalshale.com <br />
