is There is no water discharged from this process, therefore no discharge permits from the State are required. An Air <br />Quality Emissions Pennit will not be necessary because emissions are well underneath the CDPHE APEN <br />thresholds. <br />Venture Resources initially applied to the CDPHE Solid Waste Division for the Tailings Impoundment, but they <br />subsequently deferred our project to the DRMS; therefore, it is safe to say the CDPHE isn't particularly interested in <br />our new waste impoundment. No hazardous wastes are handled as part of this operation. <br />6.4.20(5) <br />There are no Designated Chemicals to be used in this operation. Refer to Exhibit C, 6.3.3(2)(a) for a list of non- <br />designated chemicals to be used. There is also a complete collection of MSDS for these chemicals at the end of <br />Exhibit C. <br />6.4.20(6)(a) <br />Again, there are no Designated Chemicals to be used in this operation. <br />There is handling of potentially acid-forming material as the pre-existing waste rock is moved from it's current <br />location (Exhibit E) to the Mobile Mill Site Crusher Feed Pile. This material is being moved using a combination of <br />track-type excavator, rubber tired wheel loader, and/or dump truck. After construction of the Concrete Leachate <br />Collection Barrier, Sediment Collection Pond anud the Diversion Ditches, sufficient Best Management Practice <br />elements are in place to mitigate any run-off while the piles are being removed. Operators are instructed not to <br />broaden the pre-existing footprint of the pile and keep it within the Diversion Ditch boundary. <br />As the material is being transported to the Mobile Mill Site, the operator is to be trained not to overfill/overload the <br />loader and/or dump truck to prevent spilling of material unnecessarily. Any loose material on bed rails, bumpers, <br />etc. is to broomed off at the load site to keep it from spilling off on the road. Should a spill occur, the operator is to <br />be trained to stop the machine and shovel up any spilled material back into their loader/dump truck for transport to <br />• the Crusher Feed Pile. <br />Once at the Crusher Feed Pile, the operator is to be trained to dump the load entirely within the confines of the <br />concrete pad and containment berm of the same. The Crusher Feed Pile is designed to contain any potential acidic <br />runoff and/or seepage. A maximum of 200 tons of material can be contained in this area for any period of time. The <br />surface of this area is to be concrete paved and sheltered with a roof to prevent any acidic run-off and potential <br />seepage. Additionally, the stuface slopes 114" -1' towards the rear where a 10" wide x 48" high concrete wall <br />provides a berm to contain any residual moisture or sedimentation. The opened face of this stricture shall be <br />protected with a heavy canvas curtain that can be closed during a rain/snow event. The surrounding grade will be <br />sloped to ensure run-off will not enter the structure. Construction and grading details can be found in Exhibit E, <br />drawing E 15. <br />The Crushing Plant operations are established to completely consume (on a daily basis) any material contained in <br />the Crusher Feed Bin to limit exposure. All of the crushed rock is stored in a Crushed Rock Bin. This bin can hold <br />80 tons of material. A removable roof covers the bin to keep the weather out and prevent any acidic runoff. <br />In the event that there is a leak in the double-walled process water pipeline system that is sufficient to breach to the <br />environment, the operators are instructed to STOP operations and isolate the pipeline by closing appropriate valves <br />to prevent continued process stream flow. The pipeline shall then be repaired. The area should be allowed to <br />evaporate any escaped liquid water. Any remaining solid residues shall be collected in buckets, etc. and disposed of <br />in the lined tailings impoundment. To further reduce the potential for pipeline leaks, all lines containing process <br />solution or tailings shall be drained when the site is unmanned. A leak event in this pipeline system is subject to <br />Rule 8 reporting requirements. See Exhibit 8 for reporting procedures. <br />The gravity and flotation concentrate products that are collected and stored in Intermediate Bulk Shipping <br />Containers which are palletized polyethylene containers surrounded by a steel skeleton framework for protection <br />from impact and crushing. These containers measure approximately 42" cubic. It shall be noted these containers <br />meet stringent DOT standards for transporting this specific material. <br />Page 3 of 31
