The water balance uses the same approach as approved for Amendment No. 8 <br />and reflects the ADR Expansion, current ore loading schedules, VLF design and associated solution <br />management. <br />The results of this water balance demonstrate that there is sufficient solution storage capacity within the Phase <br />I, II/III, and IV PSSAs and the external storage pond to safely contain the predicted process solutions, monthly <br />precipitation, instantaneous 12 hour VLF drain down volume and 100 year 24 hour storm volume. <br />As per our discussions, it is CC&V's understanding that this water balance addresses the Division's questions <br />with regard to the revised water balance and the ADR Expansion. <br />CC&V agrees with using the recently published value of $0.19 per cubic foot for building demolition costs in <br />determining the financial warranty for the ADR Expansion. Use of this cost modifies the demolition costs and <br />associated administrative costs to a total of $103,464 for the financial warranty for the ADR Expansion. This <br />amount may be deducted from the $488,095 surplus warranty currently held by the Division of Minerals and <br />Geology, leaving a remaining surplus warranty voluntarily posted by CC&V of $384,631. <br />Please contact me at (719) 689-405E <br />Since <br />.-~- <br />Phil Barnes <br />Manager Environmental Resources <br />xc: Bill Johnston, Teller County Plan <br />Enclosure: Phase IV Valley Leach F <br />should you have questions. <br />Permit #: f~-«~fl ~ ~w Confidental?: <br />Class: ~ r Type-Se ~ <br />From: To;~~1~- <br />Doc.
