Hydrologic Balance, Off-Site Damage, Site Stability: After mining is complete, the <br /> large underground openings are expected to partially fill with water, then overflow at the lowest <br /> quarry portal during high runoff periods. Since the quarry does not generate large volumes of <br /> water, and all runoff from the quarry area eventually feeds into Yule Creek, no significant <br /> impacts are anticipated on the hydrologic balance of the area. <br /> The owner of the Yule Lode Claim No. 4530,just to the north of the affected area <br /> evidently intends to make a claim that CYNIC caused off-site damage from its operations. <br /> Whether significant damage has occurred, and the extent of such potential damage, will be <br /> determined by Division of Minerals and Geology personnel in June of 1999. By submitting this <br /> permit application, Sierra does not assume responsibility for any possible off-site damage caused <br /> by CYMC. Sierra intends to conduct its operations entirely within the affected area as defined <br /> by this application. <br /> The marble waste piles from past operations have been left with slopes estimated at <br /> approximately 1.6:1 to 1.8:1 (horizontal:vertical). These piles have remained stable for over 50 <br /> years due to the large size and competent nature of the marble blocks. Sierra plans to deposit <br /> waste so the final slope in areas where waste is added to existing piles is 1.8:1 or lower. The <br /> anticipated future use of the site is recreation and tourist sight-seeing. The Reclamation Plan <br /> section of this application describes the measures Sierra intends to take to ensure a stable <br /> configuration for the site. <br /> (m) Processing on Site: Sierra anticipates no processing on site except for marble <br /> cutting or polishing operations. Such processing operations will occur underground and involve <br /> no process chemicals. <br /> (n) Primary Commodities: The primary commodity produced is dimension stone in <br /> the form of white marble blocks, slabs, and tiles. These may be further processed off-site, for <br /> eventual sale to large and small marble installation shops around the world. The end use of the <br /> material is for architectural, sculpture, and monument applications. Secondary commodities <br /> produced may be waste marble to be crushed and processed off-site for use in landscape and <br /> other applications. <br /> (o) Incidental Products: There are no incidental products to be produced by the quarry. <br /> 18 <br />
