~~ ~': <br />refuse haul road. As explained earlier, muddy conditions prohibited travel into Ore Refuse Pond 4 area so pumping <br />j water to the easiest access pond (Refuse Pond 2/3) was the best option. Mr. Routten agreed with our remedietion plan <br />/ to treat the influent water with floceulent and therby increase retention time in both refuse ponds. Both ponds did not <br />!~ appear to settle the colloidal solids rapidly enough. ENACT 7883 (Aluminum Chloride) flocculent was added to the <br />influent at both ponds and 2 smell sediment catc4 basins were constructed at the influent entrance on both the east and <br />west side of Refuse Poad 2/3. <br />At approximately 10:30 am ,later in the morning of March 2, Mr. Chervick received a call from Mr. Jim <br />Chubrillo ,Water Quality Control Division inspector. Mr. Chcrvick informed him of the situation and that all <br />remediation efforts were being coordinated with the Division of Minerals and Geology. Mr. Chubrillo stated that he was <br />satisSed with the plan and that Mr. Chervick should send him and Ms. Kalamen a letter explaining the violation and <br />treatment plan that the Deserado Mine followed. Mr. Chervick agreed to document the treatment plan and to send <br />copies to all appropriate regnls[ory agencies. This letter,therefore ,serves the purpose of agency notification. <br />To date both ponds have been pumped down significantly and no discharge has since occurred. The major <br />svowmelt event has passed and aU the refuse area snow fins melted. Influent water to both ponds now slowed to minimal <br />to zero flow. <br />If }'ou have any questions couceming the enclosed data please contact me at (303) 675 - 8431 Extension 247. <br />Sincerely . <br />T® Chervick, <br />Environmental Coordinator <br />Enclosure <br />ce: Mike Weigand <br />1e6Dubbert <br />Mr.1im Chubrillo, I)isbicl Engineer, Water Quality Control Division <br />Ms. Barbara Pavldc.
