M.D. <br />Executive Director <br />CERTIFIED NAIL N0: 149 902 270 <br />We have recently received information from the Colorado Mined Land Reclamation <br />Division (Ct4.RD) which may affect your Colorado Discharge Permit System (CDPS) <br />permit. This concerns discharges from spoils springs. CMLRD has identified <br />the following area(s) at your site as being sources of spoils spring water: <br />A spoils spring discharging to <br />Pond No. 5 <br />Any such discharges may be considered as point sources or contribute to a <br />point source discharge and are therefore subject to CDPS Regulations. Your <br />permit does not currently authorize such discharges. <br />If such discharges do in fact eziat, you should immediately write our division <br />to request a perait amendment. Your request should include the number of <br />spoils spring sources, any treatment provided, volume of water generated from <br />these sources, results of any analyses of such spoils eater, the date <br />discharges began, receiving waters sad any other related information. A Bite <br />sketch should be included, which show at a minimum, the location of each <br />discharge, flow path to the eedimeatation pond, if applicable and the <br />receiving ester. If spoils ester flow into a sedimentation pond, please <br />elate in your narrative whether the pond ie sized to handle this water in <br />addition to surface runoff and whether the CMLRD has approved of routing this <br />ester through the pond. <br />Please note that even if the spoils ester flows into a pond which has an <br />authorized discharge point, your permit does not now authorize discharge of <br />this source. The permit wa written to address surface runoff discharge• only <br />from this point. Tha spoils spring discharge ie considered to ba a change in <br />discharge sub~eet to Part II.A.1. of your permit. <br />O •C <br />0~ <br />DEPARTMENT <br />~ 18T6 rt <br /> <br />K ~V~~ <br />OF HEALTH <br />4210 EAST 11TH AVENUE DENVER, COLORADO 80220 PHONE (303) 320-8333 <br />
