COLORADO <br /> \/ Division of Reclamation, <br /> ® Mining and Safety <br /> Department of Natural Resources <br /> Date: September 29,2020 <br /> To: Tabetha Lynch <br /> CC: Jason Musick <br /> From: Zach Trujillo <br /> RE: Foidel Creek Mine,DRMS File No.C-1982-056 <br /> Foidel Creek Mine MR20-317 Second Review Memo <br /> Tabetha, <br /> As requested I have reviewed Foidel Creek Mine's (Foidel)response to the Division's adequacy letter <br /> dated September 21,2020 for the proposed suspension bridge for a 200-foot section of the Overland Belt. <br /> In my original interoffice memo,I requested for Foidel to provide information on how the proposed <br /> suspension bride will resist potential ground movement and remain stable.Foidel has provided additional <br /> information that has satisfied my request.Based on what has been provided,the proposed anchor and <br /> caisson areas have been monitored over the past three years and no movement has occurred. The anchors <br /> are placed an additional fifty feet beyond the caissons in an area with a lower gradient and well outside of <br /> the known slide area as well.Foidel states that based on site knowledge and monitoring,they do not <br /> foresee any potential shift or movement that would affect the stability of the suspension bridge based on <br /> the location of the anchors and caissons. <br /> I have no remaining comments and this concludes my review of Foidel's MR20-317. If you have any <br /> questions,feel free to contact me. <br /> Sincerely, <br /> Zach Trujillo <br /> Environmental Protection Specialist <br /> (303) 866-3567 ext. 8164 <br /> Zach.Trujillogstate.co.us <br /> Foidel Creek Mine MR20-317 Memo September 17,2020 <br /> 4F COlO <br /> I H o <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br /> Jared S.
