There is handling of potentially acid-forming material as the pre-existing waste rock is removed from it's current <br />location (Exhibit E) to the Venture Resources' Hukill Gulch Millsite. This material is being moved using a <br />combination of track-type excavator, rubber tired wheel loader, and/or dump truck. Best Management Practice <br />elements (in the SWMP) are in place to mitigate any run-off while the piles are being removed. Operators are <br />instructed not to broaden the pre-existing footprint of the pile and keep it within the Affected Area boundary. <br />As the material is being transported offsite, the operator is to be trained not to overfill/overload the loader and/or <br />dump truck to prevent spilling of material unnecessarily. Any loose material on bed rails, bumpers, etc. is to <br />broomed off at the load site to keep it from spilling off on the road. Should a spill occur, the operator is to be trained <br />to stop the machine and shovel up any spilled material back into their loader/dump truck for transport. <br />Please refer to the explicit operating parameters in Exhibit C for more information. Additionally, Exhibit D details <br />reclamation measures for the Affected Area. <br />'There is no acid mine drainage from any adits, tunnels, or underground mine workings on this site either pre- <br />existing or proposed. <br />6.4.21(6)(b)(i) <br />There are no Designated Chemicals to be used in this operation. <br />There are no hydrometallurgical extractive processes proposed as part of this operation, at this location. <br />6.4.21(6)(b)(H) <br />To avoid redundancy, the handling methods of potentially acid forming waste rock have been described at length in <br />Exhibit C and above in 6.4.21(6)(a). <br />Additionally, Exhibit D specifies reclamation measures for the Affected Area. <br />6.4.21(6)(b)(iii) <br />Venture Resources will adhere to the operations plan set forth in Exhibit C. This plan has been devised to prevent <br />adverse off-site impacts through measures of stormwater control, operator training, carefully monitored processing, <br />routine inspection of equipment, etc. <br />The reclamation measures set forth in Exhibit D shall also apply for periods of Temporary Cessation; however, due <br />to the very short duration of removing the approximately 1,000 tons of material this is not anticipated. <br />6.4.21(6)(c) <br />There is approximately 1,000 tons of pre-existing abandoned mine waste rock currently contained within the <br />proposed Affected Area area. This material is going to be removed and processed, offsite, to remove acid forming <br />materials (sulfide minerals and heavy metals). A detailed explanation of this process is found in Exhibit C and <br />Venture Resources' Hukill Gulch Millsite Pen-nit #M-2009-076. <br />This treatment provides a net benefit of 2-3 order of magnitude, in many cases, when compared to its pre-existing <br />state. Refer to the waste stream characterization before and after analysis in the appendix of Exhibit C of Permit <br />#M-2009-076. The resulting tailings are essentially non-acid forming and impounded offsite. <br />The fate of acid forming material at this site is elimination through complete removal to an offsite processing facility <br />coupled with a reclamation plan that ensures the processing site is neutralized upon cessation of the operation. <br />6.4.21(7)(a) <br />The proposed operation is essentially converting m area containing pre-existing abandoned waste rock into an area <br />void of acid forming material. <br />Page 3 of 11
