• Soil Stockpile(s) • Mine Fan and compressor building • Coal Stockpile and facilities pad • Drainage and Sediment Control Structures • Ponds and pump house • 1,000,000 gallon water storage tank In addition, one 12,000 gallon double- walled diesel tank would be temporarily placed adjacent and southeast of the Maintenance Shop along with a 1,000 gallon unleaded gasoline tank. Once construction activities are complete a permanent fueling station will be built and the tanks would be moved to a new location. The use of explosives is expected as part of the portal excavation. PSCM would store ammonium nitrate (as a crystalline solid) for explosives use in an additional temporary tank located adjacent to the Wadge Pond as specified in 2.05.3 -MIA Mine Facilities Map. Once construction activities are complete the tank will be removed. During the initial permit term, it is anticipated that coal will be moved from a small on -site storage stockpile to nearby customers by over - the -road tractor - trailer units. A more detailed description of the surface facilities is provided in Section 2.05.3. The PSCM operation under this permit application, including the production schedule and area of underground disturbance, will be dependent on conditions encountered and information gained during mining and the market demand for the coal. The annual production is expected to range from 500,000 to 2,500,000 tons during the initial five -year permit term. If mining conditions, coal availability and markets prove favorable, production could reach up to 12,000,000 tons of coal per year. Oaeration Descriation Previous mining operations in the area include the Yoast Mine which adjoins the western boundary of the permit area, and the Seneca II Mine which overlaps the eastern side of the permit area. These surface mines recovered Wadge Seam coal from areas of near - surface reserves along the anticlinal structures bounding the targeted PSCM reserves. The Yoast and Seneca II Mines ceased operations once the economically recoverable near - surface reserves were depleted and have been reclaimed. The PSCM will develop and mine the deeper Wadge Seam coal reserves in the synclinal basin between the former Yoast and Seneca II mines. Coal development and initial production will be initiated near the eastern portion of the PSCM permit area using surface facilities located in the Little Grassy Creek sub - watershed. Development and mining during the initial five -year permit term will involve excavation of the portal face -up area, construction of limited surface facilities, and exploratory development of mains, sub - mains, and four entry sections. Surface facilities developed for the first five -year permit term will be used to support initial exploratory development and the associated limited coal production and would then also be utilized to support any subsequent future full -scale mining operations. Future permit revisions will be prepared and submitted for CDRMS review and approval to address any expansion and extension of development and mining activities beyond the initial permitted exploratory development activities and for any additional facilities or disturbances required in the future. Map 2.05.2 -M1, Life of Mine Plan Map, outlines the proposed development areas for the initial five -year permit term. New surface facilities in Little Grassy Creek watershed will include the mine portal face -up area, temporary topsoil and overburden stockpiles, a coal stockpile, and coal handling facilities, Midterm Review 2.05 -5 Revision 04/2013
