Mr. Phil Barnes Chief Environmental Coordinator Cripple Creek & Victor Gold Mining Co. P.O. Box 191 Victor, CO 80203 Re: Technical Revision # 40, Addition to the ARD building in lieu of a new building in the Phase IV area as approved in Amendment # 8, Permit # M- 1980 -244. Dear Mr. Barnes: The Division has reviewed your technical revision requesting to add to the existing ARD (Adsorption, Desorption and Recovery ) building, rather than build a new ARD building in the Phase IV area as approved in Amendment # 8. The improvements to the existing building are supposed to facilitate the added solution that will be encountered once the Phase IV leach pad is in place. According to the request, once the improvements are in place, the system will be able to pump through the pregnant and barren solution pipes, approximately 24,000 g.p.m. The approximate total solution that was to be pumped through these pipes, as approved under Amendment # 8 was 22,000 g.p.m.. Please provide information, on how, CC &V is able to achieve the added pumping rate . Are there plans to install larger pumps ? As you stated in your TR request, additional information on pumping rates, capacity and solution management and water balance, will be provided as needed. Since, CC &V's Board approved operational solution for the facility is at 80 % of the total storage capacity of the pregnant ponds, those information are needed to make sure the 80 % capacity is not exceeded. In addition the financial warranty calculated for the demolition of the building assumed a 0.17 cents/ cubic foot cost, rather than 0.19 cents /cubic foot. It also failed to include the administrative cost. The Division's calculated warranty for the demolition of the building is $103,464.00 rather than the $76,508 as submitted in the TR. That amount will be deducted from the $ 488,095 surplus financial warranty in place for the site. This will leave CC &V a surplus warranty in the amount of $384,631 for permit # M- 1980 -244.
