SHELTON, Director <br />September 11, 1984 <br />Mr. Vance Mills <br />Trinidad Basin Mining, Inc. <br />P.O. Box 783 <br />Trinidad, Colorado 81082 <br />• <br />Re: Adequacy Concerns on Technical Revision for Additional Sediment Control <br />in Pit No. 5 (Pond 15-P20A, Dike TD-1 and 2) (Our File C-048-81) <br />Dear Mr. Mills: <br />Candy Thompson of our office has the following concerns which need to be <br />resolved prior to the Division approving this revision. <br />Sediment Pond 15-P 20A <br />The screw-on cap design for the PVC dewatering pipe has proven to give <br />problems at the TBM mine. The caps are frequently missing. Some method of <br />disallowing non-controlled removal of the caps must be submitted. <br />Ditch 7D-2 <br />The point at which the proposed ditch meets the existing ditch, appears to be <br />at least 5 feet downgrade of Pond 15-Pg. The applicant should resubmit a <br />drainage control plan for this area. An alternate approach could be <br />considered such as routing drainage from Td-1 and TD-2 through culverts under <br />the haul road to a sediment pond located on the south side of the haul road. <br />Ditch TD-1 <br />A properly sized culvert is needed where this ditch passes under the haul road. <br />If you have any questions please feel free to call. <br />Sincerely, <br />Michael S. Savage <br />Reclamation Specialist <br />MSS/ygt <br />Doc. No. 4022 <br />cc: Mr. Ben Quinn <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel. (30~) 866-3567 <br />
