1992 MR-19 Pneumatic Coal Drying /nstallation 'Page • 2 <br />2.04 ENVIRONMENTAL RESOURCES <br />Information on environmental resources presented in Section 2.04 of the EFCI Permit <br />Application document addresses the entire Southfield Permit Area, including the site of the <br />proposed dryer installation. Also, installation and operation of the proposed coal dryer will not <br />result in any significant additional environmental impacts beyond those contemplated in the <br />existing permit application. <br />2.05 OPERATION AND RECLAMATION PLANS <br />Installation of the proposed pneumatic coal dryer will involve limited construction within the ~ <br />existing disturbance area currently utilized for coal storage and handling. Construction will ~~1 <br />specifically involve the following activities: /`v4~ <br />• Install Foundation Structures ~i~'f S <br />• Erect Hopper Structure <br />• Install Cyclone Dryer <br />• Erect Pneumatic Pipeline, Walkway and Support Structures <br />• Install Modular Feeder and Pump Systems <br />The configuration and relative locations of each of the structures identified above are shown on <br />the Mine Surface Facilities Map, (Map 18), with plan and elevation details more cleazly <br />illustrated by Figure 19-1, Pneumatic Coal Drying System -Conceptual Design. Construction <br />activities, as well as operational and reclamation considerations are discussed in the following <br />sections. <br />INSTALL FOUNDATION STRUCTURES <br />In order to insure long-term stability and structural integrity, adequate foundation structures will <br />be required for both the product surge hopper and truss supports. The surge hopper and <br />columns which will support the integrated truss/walkway/pipeline structures will be mounted <br />on concrete footings poured around driven steel pilings. The hopper will require eight footings <br />spaced evenly on the hopper perimeter as shown on Figure 19-1, Pneumatic Coal Drying System <br />- Conceptual Design. The support columns will each be mounted on separate footers with <br />extended piling supports to provide additional rigidity. <br />ERECT HOPPER STRUCTURE <br />The hopper structure will be apre-fabricated steel bin with supporc legs, discharge chute and <br />slide gate, and upper support strutture for the cyclone dryer and integrated <br />truss/walkway/pipeline structure. The hopper structure, which will weigh approximately 50 <br />tons empty and will provide surge storage capacity of 300 tons, will be erected using a mobile <br />crane and mounted on the previously constructed foundation structures. <br />ACZ /nc. • P.0.
