RULE 2 PERMITS <br />2.05.3 (6) Overburden <br />The complete description of the removal, handling and storage of all overburden material within the <br />permit area is described under the Production, Methods and Equipment Section found at the beginning of <br />Section 2.05.3. The spoil handling procedures and spoil monitoring plan parameters for the operation can <br />be found on page 2.05 -8 of Volume 1. The mining sequence for the planned operation is shown on the <br />Mine Plan Map (Map 23A). Cross sections showing the mining operation during the "steady- state" <br />operation are found on the Mining Range Diagram (Map 24B). For the spoil disposal locations and <br />volumes for both the East and West Taylor valley fills and the temporary overburden stockpile, please <br />refer to Map 35A. The cross - sections that are associated with the design of the valley fills and the <br />temporary stockpile can be found on Map 40A. <br />Permanent Valley fill construction and design criteria is described in detail in Section 4.09 of the South <br />Taylor permit revision <br />A temporary overburden stockpile will be built above the East Taylor valley fill. The spoil suitability <br />and special handling procedures are described in detail in section 2.05.3(1) of the South Taylor <br />permit revision. The initial development of the stockpile is anticipated to begin during the year 2008 <br />with continued development occurring over the next five to eight years of operation. As for the <br />design of the temporary overburden stockpile, it will be constructed in 50 foot lifts by use of trucks, <br />dozers and loaders. The side slope of the active dump will not exceed a 1.3h:1v overall slope and <br />will be maintained during active times of operation. Maintenance techniques will consist of blading <br />of roads and ramps, along with the use of dust control during active times of operation. During <br />construction, a dozer will be used to develop and spread the end -dumps created by the trucks, this <br />will be the primary method used to build the temporary overburden stockpile. Sediment control will <br />be implemented to ensure adequate containment of potential runoff throughout the life of the <br />operation. Temporary seeding may be employed during inactive times of operations on the <br />temporary stockpile to reduce the erosion potential. Following the completion of mining, this <br />temporary overburden stockpile will be removed and placed back into the open pit. <br />South Taylor /Lower Wilson — Rule 2, Page 99 Revision Date: 12/6/10 <br />Revision No.: TR -81 <br />
