Both additions will connect to the existing Wazehouse structure as shown on Figure <br />EX49H-Fl. The Wazehouse expansion will provide needed additional temporary storage space for the parts and <br />supplies necessary to support both the permitted mine expansion and the new Washplant (TR07-60). <br />The proposed Wazehouse expansion azeas will be contained within the existing disturbed azea "envelope" defined by <br />the outer edges of the current Warehouse facility, and will result in no new surface disturbance. Construction will <br />involve limited excavation for the floor slab for the enclosed extension, shallow drilling for concrete support piers for <br />both the enclosed extension and the covered shed storage, forming and pouring the piers and floor slab, erection of the <br />pre-fabricated support frames for both extensions, and placement and connection of the metal sheathing walls and <br />roof. At such time as the Warehouse facility is no longer needed to support ongoing or future mining and related <br />operations, or permitted as a permanent facility to support the postmining land uses, it will be demolished, and the <br />associated disturbance azeas reclaimed. <br />This submittal includes revised PAP text, exhibits, and maps, addressing the location, configuration, operation, <br />maintenance, and reclamation of the proposed Wazehouse expansion. New and revised PAP materials are identified <br />by the attached Smnmary of Revisions/Additions. TCC would like to proceed with this project as soon as possible, so <br />that construction can be completed under favorable weather and ground conditions. After you have opportunity to <br />review the accompanying information, please feel free to contact me with any questions or to discuss submittal <br />materials or related matters. <br />Best regards, <br />Twent oal Co any <br />Je - .
