When placed on the active dumping areas of the VLFs, the PSES filtrate will be <br /> dumped over the face and intermixed with durable material. Through dumping <br /> filtrate material and ore, then pushing it over the face, the combined material will <br /> effectively be mixed during placement on the VLFs. <br /> The filtrate material will comprise approximately 0.01% of the total amount of <br /> material placed on the VLFs each day. Consequently, the minimal volume of PSES <br /> filtrate, mixed with ore, will have no measurable impact on geotechnical stability in <br /> the placement area. <br /> 3. Filter press product: Modification #3 discusses transporting a filter press product from the PSES <br /> to the VLFs. Similar to Comment 2, the Division has the following questions and concerns: <br /> a. Assuming the filter press product is intended to or will increase the pH of the VLFs, <br /> please provide some narrative to address the following: <br /> i. The toxicity and potential environmental impacts of the filter press product, <br /> CCV's response to comment 2.a.i addresses this comment. <br /> ii. The anticipated volume of the filter press product, <br /> CCV's response to comment 2.a.ii addresses this comment. <br /> iii. If the truck transfer of this material will occur off lined areas, and <br /> CCV's response to comment 2.a.iii addresses this comment. <br /> iv. As the Division understands the Arequa Gulch VLF is already at maximum build- <br /> out, where would this material be placed on the AGVLF? <br /> CCV's response to comment 2.a.iv addresses this comment. <br /> b. The filter press product will be relatively fine grind. No discussion was provided for <br /> potential impacts to geotechnical stability of the VLFs with the introduction of this <br /> material. Please address the impacts on slope stability. <br /> CCV's response to comment 2.b addresses this comment. <br /> Should you require further information please do not hesitate to contact Katie Blake at 719.689.4056, or <br /> Katie.Blake(a;newmont.com, or me 719.689.4055, or Me g.Burt(a;newmont.com. <br /> Sincerely, <br /> tr <br /> Meg Burt <br /> Senior Environmental Manager <br /> Cripple Creek and Victor Gold Mine <br /> Attachments <br />
