COLORADO <br />Division of Reclamation, <br />Mining and Safety <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Inter Office Memorandum <br />To: Brock Bowles, DRMS <br />From: Robin Reilley, GISP, DRMS <br />Date: 18 July 2016 <br />RE: New Horizon C1981008 <br />Technical Revision, TR73 <br />I was requested to assess the above referenced technical revision for adequacy of <br />additional culverts and their design capacity s per Rule 4.03. My review of this <br />technical revision follows. Adequacy review questions are numbered. <br />It appears that culverts C180 and C179 are added new culverts and that culvert <br />C101 was removed. <br />As per rule 4.03, culverts shall safely pass the 10 year 24 hour event and be placed in a <br />manner to promote conveyance of design flow. Design capacity and culvert placement <br />have been met as per Rule 4.03. I have no adequacy questions regarding the above <br />mentioned Rule. <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br />John W.
