�� <br /> PIONEER RECEIVED <br /> SEP 1 ' ZU jJ <br /> DIVISION OF RECLAMATION <br /> September 16, 2019 MINING AND SAFETY <br /> Tim Cazier <br /> DRMS <br /> 1313 Sherman Street, Room 215 <br /> Denver, CO 80203 TR01 <br /> RE: J&J Stone Pit#1 M-2011-004 TC1/mac <br /> Technical Revision application6 (4t mgps 3 <br /> Dear Mr. Cazier, o <br /> m � <br /> Please accept the enclosed Request for Technical Revision Cover Sheet and application fee on o b <br /> behalf of Mike Krauth of KrauthCo. Mr. Krauth plans to increase the affected area and understands this 7 <br /> will increase the amount of the required reclamation bond. <br /> Natural features separate the current mining area from the proposed area to the west. A bluff <br /> and a suiface water drainage run north to south along the west side of the current 15-acre mining area. <br /> Mining will continue in this area and will expand west into approximately 15 acres west of the bluff. The <br /> existing interior haul road that commences at Red Canyon Road will continue to provide access to the <br /> proposed areas. <br /> 0 <br /> Mining will continue consistent with Exhibit D Mining Plan submitted in 2017 during the permit 8 o I� <br /> amendment process. The target deposit continues to be sandstone that is mined as dimensional s O <br /> landscape material. The annual production volume will increase from 70K tons to 150K tons per year. <br /> The target deposit is effectively mined as benches, progressing from south to north, resulting in a high <br /> wall along the north and west sides of the active mine area. Benches will be developed with 10 vertical <br /> ft. and 8 horizontal ft.The proposed area will also daylight to the south and east. <br /> Equipment will include a portable processing plant to crush and size rubble generated during <br /> dimensional stone production. When on site, the sizing plant will be located on a relatively level and <br /> vegetation free area along the toe of the west side of bluff mentioned previously. Approximately 5 <br /> acres will be occupied by stockpiles and the processing plant. The plant will operate less than 90 days <br /> each year but mining will continue year round, consistent with the current mining operation. <br /> Dimensional stone mining and equipment will remain consistent with AM-01. <br /> Reclamation will also remain consistent with AM-01 also. Surface material will continue to be <br /> carefully salvaged from all surfaces and stored for use during reclamation. Consistent with the <br /> reclamation plan, only the staging and processing area will require revegetation since the mining area <br /> will be exposed sandstone bedrock benches. Based on the reclamation cost summary provided by the <br /> Division in March of 2107, Mr. Krauth anticipates the appropriate bond for the additional staging area is <br /> $26, 868.68. This is an increase of$18,378.68.
