Longfellow Koehler Project <br /> Page 3 <br /> Monitoring <br /> Monitoring points for this project will consist of upstream, downstream as well as flows from <br /> adits and dumps. Monitoring will start in 1995 and continue until two years after the project is <br /> completed. Monitoring will occur four times yearly, once in the spring and fall and will be submitted <br /> annually at the same time of SGC's Mined Land Reclamation submittal. A copy will also be sent to <br /> the Water Quality Control Division. All samples taken will be analyzed for dissolved and total <br /> recoverable metals for Pb, Cu, Zn, Cd, Mn and Fe. A field pH will be taken as well as field <br /> measurements for flow. 5 ( ct <br /> Reporting <br /> SGC will submit annual reports for this project starting with finalized engineering drawings <br /> prior to onsite work starting. Once all reclamation activities are complete, a final report will be <br /> submitted. Reports will be sent to the Division of Minerals and Geology as well as the Water Quality <br /> Control Division. The report will include activities to date as well as planned activities for future <br /> years work. <br /> Budszet <br /> SGC will fund this project. <br /> Remedial Goals and Objectives <br /> Reduction of low pH, metal laden waters flowing into the headwaters of North Mineral Creek <br /> by: <br /> 1) Restoring hydrologic regime to near premining conditions. <br /> 2) Reduction of acidity in the headwaters by isolating or limiting abilities of waters to react <br /> with pyrite and other sulfide minerals. <br /> 3) Reduction of exposure to waste material by snowmelt, rainwater and intermittent streams. <br /> 4) Visually reclaim area to acceptable standards. <br /> Contingency Plans <br /> lans <br /> Should the concept of hydraulic seals not be practical after engineering studies, SGC will <br /> place an anoxic limestone drain with an improved pond as per the attached portion of the Colorado <br /> Division of Minerals and Geology report. Prior to draining of the pond, the pH will be raised to <br /> prevent harm to the environment, as described in the attached report. <br />
