Probably not good that Bowie Resources significantly changed one of their hydrology <br />models as part of TR-118, but I did not review it. I am reviewing it now as part of TR-122 though, so it is not a problem. <br />Take care. <br />Rob Zuber, P.E. <br />Environmental Protection Specialist II <br />Active Mines Regulatory Program <br />C 0 L 0 R A D 0 <br />Division of Reclamation. <br />.µ Mining and Safety <br />Department of Natural Resources <br />P 303.866.3567, extension 8113 1 Cell 720.601.2276 <br />1313 Sherman Street, Room 215, Denver, CO 80203 <br />rob.zuber@state.co.us I http://mining.state.co.us <br />On Thu, Dec 3, 2020 at 8:07 AM Trujillo - DNR, Zach <zach.trujillo@state.co.us> wrote: <br />Hey Rob, <br />Going over my adequacy review memo, my review was specific to the HBET's stability analysis of the pile under <br />Rules 4.9, 4.10 and 4.11. 1 don't recall the specifics but it doesn't seem I reviewed the SEDCAD models. <br />On Wed, Dec 2, 2020 at 1:21 PM Zuber - DNR, Rob <rob.zuber@state.co.us> wrote: <br />Hi, Zach <br />hope things went well at Colowyo. <br />During my review of TR-122 for Bowie #2, it came to my attention that the SEDCAD model for drainage at/near <br />Gob Pile #3 was updated with TR-118. As far as I can tell I did not look at that revision for Janet, but you did. Do <br />you have any insights on that revision of the SEDCAD model?
