Pave Parking Area and Helipad (MR07-220) - In 2007, in order to accommodate an increase in the number of employees working during each shift under a 12 -hour shift schedule, TCC proposes to regrade and pave the remaining portion of the East Employee Parking Area and truck staging area, and, in conjunction with grading/paving activities, to establish an Emergency Helipad. The Helipad will be established as part of our overall emergency planning and preparedness program to facilitate rapid evacuation and transport of a sick or inured employee(s) to a suitable medical facility for emergency care. The proposed paved area is an existing graveled parking area used for overflow parking and staging/tarping of coal haul -trucks. With installation and commissioning of the Truck Loadout and West Haulroad (TR's 06-53 and 06-55) truck traffic transitioned away from the Mine Entrance/Haulroad. Paving this area would help eliminate muddy conditions during wet weather and in the winter -time, and consequent dusty conditions when the mud dries and is pulverized by traffic. Paving will require minor grading work and over -excavation of existing drainage features (drainage ditches to be retained as paved swales); base preparation, consisting of grading and placement of additional road -base; followed by placement and compaction of approximately 4 (parking area) to 6 (Helipad) inches of asphalt over an area of approximately 52,200 square feet. Prior to asphalt placement, approximately 220 feet of electrical conduit will be placed and stubbed -off to facilitate future installation of site lighting. On completion of paving operations, parking places and the helicopter landing zone will be marked with high -visibility reflective paint. Security Gate Installation (MR09-240, MR10-244, TR10-75) - A Security Gate Installation is needed to enhance mine security and provide for better and more effective access control and training of mine visitors and vendors. The location of the proposed Security Gate Installation is on and adjacent to the Mine Entrance and Haulroad, as shown on Map 24, Surface Facilities and Freshwater Systems, with details provided by drawings in Exhibit 49U. The proposed Security Gate Installation will involve the following: • Completion of grading and paving of an existing dirt parking/staging area (previously approved under MR07-220) • Realignment of approximately 300 feet of the existing Ditch G-ld • Installation of a grated drainage collection basin, approximately 80 feet of 36 -inch culvert, and construction of a short connecting ditch • Foundation preparation for a modular security building within the existing disturbed area • Installation of a 1,500 gallon waste -water holding tank (sub -grade) and connecting pipeline • Installation of a 20 x 60 foot modular Security Building • Installation of a 1,500 gallon water tank (may be sub -grade) and connecting pipeline • Installation of a 1,000 gallon propane tank and connecting pipeline • Extension of a short powerhne (up to 10 new powerpoles), and installation of a transformer • Construction of approximately 100 feet of security fence • Placement of concrete barriers Visitors and vendors entering the mine property will be required to stop and check-in at the Security Gate. Site hazard training and issuance of Personal Protective Equipment (PPE), will also occur at this location. The water tank will be filled from mine sources or by a contractor, and wastewater will be periodically pumped -out and hauled off-site by a contract disposal firm. Maintenance Shop/Warehouse Facility A mine warehouse and maintenance shop facility underwent a change in use and now houses a general meeting area and office space for mine personnel. TCC utilizes the former CYCC shop/warehouse complex to work on equipment and store and dispense materials. TCC also utilizes a shop area northeast of its office; which was previously operated by CYCC as the Preventive Maintenance Bay. Uses of the shop area include construction, maintenance, and storage of materials, equipment, and various supplies. Access to the 2.5 -acre shop facility is designated on Map 24, Surface Facilities.
