This may include the construction of a waste pile stabilization structure, the <br />reestablishment of an effective sediment control structure at the toe of the marble waste piles, <br />and correcting any damage from rock movement below the quarry portal access road. if CDMG <br />does not use all of CYMC bond funds for this purpose, Sierra should receive any funds not used <br />for such purposes_ Sierra has acquired the senior secured notes of CYMC and is bt the process <br />of foreclosing on these notes. According to the terms of the notes, Sierra will be entitled to <br />recover all assets of CYMC, including any reclamation bond money to be returned to CYMC. <br />Sierra will not perform any activity that may cause can ant conditions to change where such <br />damage may have occurred or may occty in the future. Only after a solution is found to the off- <br />site damage issue, and corrective action taken to stabilize the toe area of the waste pile and <br />reestablish the effectiveness of the sediment control structure, will Sierra use this area for any <br />purpose. <br />The sediment control structure should be established with its base on bedrock and <br />constructed ofsemi-permeable materials or with asemi-permeable liner to allow water to pass <br />through while retaining marble fines. CYMC operating personnel have indicated that it was only <br />until recent years that the sediment control structure built by CYMC became ineffective. $ven <br />with marble blocks filling the pond, the pond never filled or required cleaning. The pond is <br />approximately 20 feet across and about 6 feet in depth with a total volume of approximately S00 <br />cubic feet. It was not until the stunmer of 1998, when a road was built around the outside of the <br />south waste pile and substantial quantities of marble fates were mobilized, that substantial <br />sediment buildup was observed. Sierra estimates that a similarly sized pond will be sufficient to <br />collect sediment runoffduring quarry operations, especially since Sierra does not plan to route <br />quarry discharge water into the waste piles. Periodic cleaning of the pond is anticipated. <br />The marble waste piles from pre-1941 operations have been left with s]opes 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 2:1 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 />(ml Processine on Slte: 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 />jnl Primary Commodltles: The primary commodity produced is dimension stone in <br />tl~e form of white marble blocks, slabs, and tiles. These may be further processed off-site, for <br />t _..._n ~__u_ :__•., n...:.._ .-1.....,. ~...~...A ~~P vrn«li1 Thn Ph/t f1CP AF tt1P <br />
