RULE 2 - PERMITS • Lube Storage — Includes Storage Tanks • Bath House • Fuel Tanks • Substations — Internal substations are required facility area, main substation belongs to YVEA • Pond 002 Pump Facility — facility to remain as permanent as required by the State Engineer's Office • Office • Water Well • Parking lots, fences, roads, and ancillary structures (including culverts) associated with the previously mentioned features /structures • A security building will be constructed at the boundary to the property. The security building will be a 12 x 40 foot wood -frame structure on a 15 x 45 foot, 4 -inch thick concrete slab. • A modular bathhouse 24 feet wide and 70 feet long will be placed between the shop and existing bathhouse. The temporary building will be placed on 9 concrete sleepers poured on 8 foot centers. Each sleeper will be 20 feet long, 2 feet wide and 1 foot deep. • A pump house at the Wadge Pond will be constructed to pump water out of the pond to the 1 million gallon water storage tank. The pump house will be 20 feet by 30 feet and be constructed on a concrete slab of the same size 8 inches in thickness. Mine facilities in the north end were previously bonded under the former Seneca II Mine. On approval of the PSCM Permit, the performance bond for these facilities and the associated disturbance areas were transferred to PSCM. A description of those features /structures and the associated bond amounts are presented in Exhibit 2.05.3 -E1, Mine Facilities (North End) Details. There will be additional facilities constructed or relocated to facilitate operations. These facilities include: Bath House /Septic System - A new bath house and septic system will be installed to accommodate mine employees. In order to determine the type of septic system required test pits will need to be excavated just west of the existing bath house /warehouse (see Figure 1). Two pits will be excavated to a depth of approximately 8'. Soil profiles will be recorded and the pits will be immediately backfilled and area reseeded. Replacement Water Well - A new domestic water well will also be required to accommodate the new bath house in addition to the office facilities. The new well will replace the existing well with a new pump and chlorination system. PSCM proposes to drill a test hole (755'x 5 5/8 ") approximately 100' west of the existing well to check for a viable source of water. If a viable source is not found the hole will be backfilled and another nearby location will be drilled. Replacement Power Poles and Installation of Fiber Optics Line - There is an existing 4,160 kV line running from the YVEA substation to the Sage Creek Office facilities. The condition of the poles and associated power infrastructure is poor and currently unable to accommodate needed fiber - optic lines. PSMC will replace the poles and line and move them slightly east and away from their current location along Little Grassy Creek. The line would instead run along the haul road. The existing poles will be removed. MR -05 2.05 -11 Revision 08/11
