AA <br /> V V <br /> MineW,iter <br /> d. Petition the WQCC of the State of Colorado for feasibility—based limits for the <br /> discharge from the Mine and the affected/impaired segments of North and South <br /> Mosquito Creek and of Mosquito Creek; to allow for focused treatment of the <br /> worst quality waters and the allocation of limited financial resources to address <br /> the largest and most concentrated contaminant loads. <br /> 2. Reduce the potential (magnitude and frequency) of catastrophic releases of metal laden <br /> sediment from the historic Mine workings (comprising 35 miles of tunnels much of <br /> which have not been accessible for many decades) by managing surface water and <br /> sealing workings to prevent or decrease ingress of water and oxygen into the pyrite-rich <br /> zones of the Mine: <br /> a. Installing polyurethane foam seals at accessible openings including shafts and <br /> vent raises of the mine, as feasible; <br /> b. Divert surface water away from openings to the mine by constructing run-on <br /> controls, as feasible or accessible; <br /> c. Inspecting the surface of the Mine areas for evidence of collapses and plugging or <br /> sealing these areas to decrease the magnitude of air flow into such areas, and/or <br /> diverting surface water away from such areas, as feasible or accessible; <br /> 3. Develop further water resources, as feasible, through drilling and/or tunneling into the <br /> Syncline formed by and adjacent to the London Fault, from the existing decreed <br /> conditional water rights (W8314-76) to increase the flow of water(including during low <br /> flow) into the Creek, <br /> a. During the course of water development MineWater may encounter materials that <br /> contain recyclable or recoverable levels of metals (including gold, silver, copper, <br /> lead, and zinc). Recovery of metals during the course of water development shall <br /> not constitute mining or make MineWater or the BFPP an Operator or Owner <br /> under CERCLA if the recovery activities are limited in scope to the bona fide <br /> mining activities as required to develop and stimulate water production. <br /> 4. Evaluate existing mine wastes and, to the extent economically feasible, <br /> a. Prioritize our evaluation to waste rock piles that are closest to surface water <br /> resources including South Mosquito Creek and No Name Creek; <br /> b. recycle or recover previously mined waste materials presently disposed of on- <br /> surface at the Mine for reprocessing off-site and for subsequent disposal at a <br /> lower-precipitation area with capping of all wastes (if taken off-site); <br /> c. construction of a reprocessing area, potentially in an area as dictated by <br /> economics and likely within 150 miles of the Site receiving less than half the <br /> existing annual precipitation incident to the London Mine area, to receive wastes <br /> from the London Mine area and from other areas as feasible; <br /> d. cap, cover and/or regrade remaining on-site wastes to reduce the potential for <br /> erosion or leachate generation from these wastes <br />
