6.4.21(1)(c)(iii) <br />Same as 6.4.21(1)(c)CH) <br />6.4.21(1)(c)(iv) <br />There will be no newly placed waste rock piles as part of the proposed operations. <br />There is, however, pre-existing abandoned waste rock (amounting to approx. 1,000 tons) located in the Affected <br />Area. All pre-existing waste rock shall be removed offsite to the Venture Resources' Hukill Gulch Millsite in Clear <br />Creek County (DRMS Permit # M-2009-076). <br />6.4.21(1)(c)(v) <br />During the removal process of the pre-existing waste rock pile, there will be some minimal intermediate stockpiling <br />within the area already containing the pre-existing waste rock to facilitate loading tricks. <br />Construction and grading details can be found in Exhibits C, D. and E <br />6.4.21(1)(c)(vi) <br />All pre-existing waste rock shall be removed offsite to the Venture Resources' Hukill Gulch Millsite in Clear Creek <br />County (DRMS Permit # M-2009-076). Mineral processing and treatment will occur at that location. The newly <br />generated tailings, in a relatively inert state, will be impounded in that location. <br />6.4.21(1)(c)(vii) <br />No in situ leaching operations will be performed at this location. <br />6.4.21(2) <br />Refer to the maps within Exhibit A and E for locations of pre-existing acid-forming materials. <br />6.4.21(3) <br />The only other known requirement for environmental protection measures from other jurisdictions at this location <br />pertain to CO Water Quality Control Division's stormwater management provisions. Refer to Exhibit C for <br />specifics regarding the Stonnwater Management Plan and SWMP permit requirements. <br />The groundwater generated from drainage of this area is hydraulically connected to the Argo Tunnel, which lies <br />directly beneath the Affected Area. The US EPA and the CDPHF_, are currently doing extensive monitoring of this <br />groundwater. The Argo Tunnel drainage is monitored, collected., and treated at the Argo Tunnel Treatment Facility <br />located in Idaho Springs. The proposed operation will NOT adversely affect this monitoring and as time goes <br />forward the should begin to see an improvement in auahty because we are removing point sources of acid runoff a <br />net reduction of acrd forminR materials. <br />6.4.21(4)(x) <br />There are no other known permits or local licenses needed in order to proceed with operations concerning the <br />handling of potentially acid-forming, pre-existing waste rock. Again, no designated chemicals are being used as part <br />of operations. <br />There is no water discharged from this process, therefore no discharge permits from the State are required. An Air <br />Quality Emissions Permit will not be necessary because emissions are well underneath the CDP1-JE ADEN <br />thresholds. <br />No other hazardous wastes are handled as part of this operation. <br />6.4.21(5) <br />There are no Designated Chemicals to be used in this operation. <br />6.4.21(6)(a) <br />Again, there are no Designated Chemicals to be used in this operation. <br />Page 2 of 11
