This <br />request is submitted pursuant to C.R.S. 37-92-308(4), referencing the plan for augmentation <br />applied for in case no. 10CW31. <br />Notice has been provided to the objectors in Case No. 1 OCW31 on August 12, 2010 and <br />no comments have been received. The required fee of $300 has been received (transaction <br />number 3646898). <br />PLAN OPERATION <br />CC&V operates a surface mine in the vicinity of the towns of Cripple Creek and Victor. <br />The mine intercepts precipitation, which causes depletions to adjacent streams. This SWSP is <br />based on the methodology of a current SWSP for the main mining areas, and covers only the <br />Mine Life Extension area which consists of approximately 123.75 acres. <br />DEPLETIONS <br />Stream depletions occur to Fourmile Creek and Beaver Creek from various mining <br />operations. First, CC&V's gold mining operations contain areas (such as leaching pads, fuel <br />farms, etc.) permitted by the Division of Reclamation Mining & Safety to be zero-discharge, <br />which capture all precipitation and result in a reduction of runoff from precipitation. You have <br />calculated maximum monthly depletions to the Fourmile Creek drainage based on the maximum <br />number of acres of zero-discharge area that will occur. Zero-discharge areas within the <br />Fourmile Creek drainage are subdivided into those overlying the volcanic diatreme (a more <br />porous geological area containing the mined deposits) and those outside the boundary of the <br />diatreme. Capture of precipitation is considered to affect stream flow on a lagged basis, and <br />CC&V has computed lagging for each area separately. Should the actual amount of a zero- <br />Office of the State Engineer 6- <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 <br />www.waterstate.co.us
