Changes in permitted disturbed and affected area acreages during 2007 included an increase in the <br />permitted disturbance acreage of 7.7 acres (TR07-60 and MR07-224), and in the permitted affected <br />acreage of 327.7 acres (PR06-07, TR07-60 and MR07-224). Actual surface disturbance during 2007 <br />matched the increase in permitted disturbance, resulting in a cumulative total for actual surface <br />disturbance of approximately 498.1 acres. Please refer to the revised maps and text associated with <br />PR06-07, Addition of NMD Reserves and Modification of Mining Configuration, TR07-60, Thickener <br />Underflow Pipeline and Borehole, and MR07-224, 6MN Water Transfer pipeline, for specific details. <br />No backfilling, grading, topsoil replacement, or revegetation occurred during 2007. No reclamation of <br />previously disturbed areas occurred. There are several areas on the attached "2007 Annual <br />Reclamation Report Disturbed Acreage" summary that are identified as "Reclaimed". These areas <br />have previously been regraded and stabilized with vegetation, however, TCC has not pursued bond <br />release for these areas due to the potential for re-disturbance in conjunction with required access and <br />site maintenance activities. During 2007, TCC completed noxious weed control spraying for both <br />active and bond-released areas, consistent with the approved Noxious Weed Control Plan (MR06-206), <br />and conducted managed livestock grazing activities on the bond-released areas. <br />Permit approvals during 2007 resulted in an increase in the calculated reclamation liability and surety <br />coverage of $412,152, to a total of $7,691,763, at year-end, summarized as follows: <br />TR07-59, Washplant 2 Construction/Modification (+$353,388) <br />TR06-60, Thickener Underflow Pipeline and Borehole (+$5,007) <br />MR07-215, Fiber-Optic Borehole (+$442) <br />MR07-216, Fish Creek Dewatering Modification (+$3,669) <br />MR07-217, Warehouse Expansion (+$22,937) <br />MR07-218, 6MN Emergency Escape Hoist (+$7,240) <br />MR07-219, Temporary Office Trailer (+$1,729) <br />MR07-220, Pave Parking Area and Construct Helipad (+$1,030) <br />MR07-222, Washplant Powerline (+$5,850) <br />MR07-224, 6MN Water Transfer Pipeline (+$7,160) <br />MR07-225, 18RT Shaft Heater (+$3,700) <br />Attached are copies of the standard form (CDRMS) Annual Reclamation Report for 2007.
