Longfellow Koehler Project <br /> Page 6 <br /> The passive bio treatment system will provide an effective approach to treatment of long term <br /> acid mine drainage and may reduce the need for and expense of active chemical treatment and <br /> minimize sludge disposal. <br /> Monitoring <br /> Monitoring points for this project will consist of upstream, downstream as well as flows from <br /> adits, seeps and dumps. Monitoring will start in 1996 and continue until two years after the project <br /> is completed. Monitoring for run on, runoff and waste isolation will occur four times yearly, and <br /> particularly once in the spring and fall. Monitoring of seeps, adit flows and any other sources feeding <br /> the passive bio treatment system will be done monthly until the plant is in operation. Once the plant <br /> is operational, SGC will monitor monthly for the first year and quarterly thereafter. All samples <br /> taken will be analyzed for dissolved Pb, Cu, Zn, Cd, Mn and Fe. A field pH and temperature will be <br /> taken as well as field measurements for flow. <br /> Reporting <br /> SGC will submit reports annually at the same time of SGC's Mined Land Reclamation <br /> submittal. A copy will also be sent to the Water Quality Control Division.SGC will submit annual <br /> reports for this project starting with finalized engineering drawings, with estimates of operation, <br /> maintenance and replacement requirements prior to starting onsite work. After two years of <br /> treatment operation, an operation and maintenance manual will be developed based on real time <br /> experience with the system. The O&M manual will be updated annually during the course of system <br /> operations. The manual will include a chronology of all activities carried out at the project site related <br /> to the following: maintaining access to the site; monitoring flow, quality, and treatment operations; <br /> delivery of quantities of supplies and equipment; maintaining flow and conveyances and treatment <br /> efficiency;changes in treatment operations;replacement of equipment and facilities, and counteracting <br /> vandalism and damages attributable to natural conditions. Suppliers and costs of materials, equipment <br /> and facilities will be included. <br /> Once all reclamation activities included in the plan are complete, a final report will be <br /> submitted. <br /> Bum <br /> Sunnyside Gold Corporation will fund this project. <br /> Remedial Goals and Objective <br /> Reduction of dissolved zinc (70%), flowing past the M-2 sampling point at the Koehler <br /> Longfellow site on Red Mountain Pass. Actions taken to reduce dissolved zinc will also reduce low <br /> pH, metal laden waters flowing into the headwaters of North Mineral Creek by: <br />
