Project Phasing to add Phase 6a: Revision of the existing permit to reflect surface mining for <br /> Phase 6a not exposing groundwater. Phase 6a will be mined prior to Phase 5a. <br /> A detailed description of the revision is below: <br /> P_r_olect Phasing to add Phase 6a: Revision of the existing permit to reflect surface mining for <br /> Phase 6a not exposing groundwater. Phase 6a will be mined prior to Phase 5a. W <br /> The approved permit has a Phase 5a for initial mining not exposing groundwater and has been bonded o lX <br /> for. After reviewing the mine site layout and logistics to mine Phase 5a there is a better way to provide a rn <br /> material from the proposed Phase 6a that is adjacent to existing disturbed area. We are requesting that <br /> this be updated to reflect a Phase 6a for initial mining not exposing groundwater. The area of Phase 6a <br /> is 11.67 acres and there is additional disturbed area between the Phase 6a and the existing disturbed <br /> area that is 1.68 acres (see attached updated mining plan). The total area needed to be bonded for is <br /> 13.35 acres. Since Phase 5a is already being bonded for (13.94 acres which is greater than the 13.35 <br /> for Phase 6a) we would like to swap the order of the phasing and have Phase 6a bonded for first as it <br /> would be mined first. Please refer to the attached revised bonding calculations for Phase 6a. We would <br /> request that current bond not be increased or decreased as it would cover the bond needed for Phase <br /> 6a since the order of mining for Phase 6a and 5a are being swapped. The current amount bonded of <br /> $2,090,100.00 would cover the amount needed for Phases 1-4 and Phase 6a. <br /> Broken Arrow Investments, LLC appreciates your consideration of this revision request and looks <br /> forward to your response. <br /> vl <br /> 305 Denver Avenue-Suite D•Fort Lupton CO 80621 • Ph: 303-857-6222•Fax:303-857-6224 <br />
