RE: 2807 Cripple Creek 8r Victor Gold Mining Company ~E~F~~~Fp
EXPIRATION DATE: December 31, 2007
Dear Mr. Shimmin & Ms. Ledet:
We have received your submittal dated Nov. 14, 2006 requesting renewal of Cripple
Creek 8 Victor Gold Mining Company's (CC&V) substitute water supply plan. The current
request is submitted pursuant to C.R.S. 37-92-308(4), referencing the plan for augmentation
applied for in case no. 02CW122.
Notice has been provided to the objectors in case no. 02CW122 on November 14, 2006,
and no comments have been received. The required fee of $300 has been received
(transaction number 3610982).
PLAN OPERATION
CC&V operates a surface mine in the vicinity of the towns of Cripple Creek and Victor
that depletes stream flows. The plan's purpose is to provide replacement water to the streams
so as to prevent injury to senior vested water rights.
DEPLETIONS
Stream depletions occur to Fourmile Creek and Beaver Creek from various mining
operations. First, CC&V's gold mining operations contain areas (such as leaching pads, fuel
farms, etc.) permitted by the Division of Reclamation Mining & Safety to be zero-discharge,
which capture all precipitation and result in a reduction of runoff from precipitation. You have
calculated maximum monthly depletions, shown in the table below, to each of the Fourmile
Creek and Beaver Creek drainages based on the maximum number of acres of zero-discharge
area that will occur in each drainage. Zero-discharge areas within the Fourmile Creek drainage
are further subdivided into those overlying the volcanic diatreme (a more porous geological area
containing the mined deposits) and those outside the boundary of the diatreme. Capture of
precipitation is considered to affect stream flow on a lagged basis, and CC&V has computed
