Exhibit D <br /> Page 18 <br /> (approximately 175,000 cubic yards)of pre-strip growth medium is slated for use in concurrent <br /> reclamation, in addition to approximately 52,000 cubic yards to be taken from TS-1,further reducing the <br /> cumulative total of TS-1 stored material to approximately 492,000 cubic yards. Some 885,000 cubic yards <br /> of process discard are projected to be placed in the PDS,bringing the total volume in the PDS to <br /> approximately 10.6 million cubic yards. <br /> Year 13: The Year 13 mining activity is planned to encompass advancing the full pit-length face to the <br /> south,effectively completing mining of the north one-half of Section 10.Planned production over the <br /> projected 76.1-acre mine block is set at approximately 5.0 million tons for the year. The full extent <br /> (approximately 124,000 cubic yards)of pre-strip growth medium is slated for use in concurrent <br /> reclamation, in addition to approximately 1,000 cubic yards to be taken from TS-1,further reducing the <br /> cumulative total of TS-1 stored material to approximately 491,000 cubic yards. Some 872,000 cubic yards <br /> of process discard are projected to be placed in the PDS,bringing the total volume in the PDS to <br /> approximately 11.4 million cubic yards. <br /> Year 14: Mining continues the full pit-length face advance to the south,remaining within the central <br /> portion of Section 10. Planned production over the projected 88.9-acre mine block is set at approximately <br /> 5.0 million tons for the year. The full extent(approximately 123,000 cubic yards)of pre-strip growth <br /> medium is slated for use in concurrent reclamation,while a surplus of about 19,000 cubic yards is to be <br /> routed to TS-1,bringing the cumulative total of TS-1 stored material back up to approximately 509,000 <br /> cubic yards. Some 873,000 cubic yards of process discard are projected to be placed in the PDS,bringing <br /> the total volume in the PDS to approximately 12.3 million cubic yards. <br /> Year 15: Mining activity in Year 15 advances the full-length pit further south within the central portion of <br /> Section 10. Planned production over the projected 93.4-acre mine block is set at approximately 5.0 million <br /> tons for the year. The full extent(approximately 139,000 cubic yards)of pre-strip growth medium is <br /> slated for use in concurrent reclamation,while a surplus of about 12,000 cubic yards is to be routed to TS- <br /> 1,bringing the cumulative total of TS-1 stored material back up to approximately 521,000 cubic yards. <br /> Some 872,000 cubic yards of process discard are projected to be placed in the PDS,bringing the total <br /> volume in the PDS to approximately 13.2 million cubic yards. <br /> Year 16: The Year 16 mining activity continues to advance a full-length pit southward in the central <br /> portion of Section 10;however,pit length begins to shorten near the end of the year due to a narrowing of <br /> the pit to accommodate oil and gas infrastructure present interior to the western edge of the Permit Area. <br /> Planned production over the projected 92-acre mine block is set at approximately 5.0 million tons for the <br /> year. The full extent(approximately 148,000 cubic yards)of pre-strip growth medium is slated for use in <br /> concurrent reclamation, in addition to approximately 600 cubic yards is to be taken from TS-1, bringing <br /> the cumulative total of TS-1 stored material down to approximately 520,000 cubic yards. Some 878,000 <br /> cubic yards of process discard are projected to be placed in the PDS,bringing the total volume in the PDS <br /> to approximately 14.1 million cubic yards. <br /> Year 17:Mining in Year 17 continues the southward progression, entering the northernmost portion of <br /> Section 15;however,full pit length is generally re-established/maintained as the east end of the pit then <br /> extends easterly(entering the NW 1/4 of Section 14)to accommodate the aforementioned oil and gas <br /> infrastructure. Planned production over the projected 88.5-acre mine block is set at approximately 5.0 <br /> million tons for the year.
