Fourth, Colowyo will need to include a plan for verification of the weed spraying <br />on the ground, during or after the contractor has been on site. This will ensure <br />that the weeds were, in fact, sprayed and that the spraying was successful in <br />killing the weeds. This verification will also need to be documented in the <br />Annual Reclamation Report each year. <br />25. Currently Colowyo has two reclamation seed mixtures in the permit, a grassland <br />seed mix and a sagebrush steppe seed mix. The areas where each of these will be <br />planted is fairly well defined for the West Pit and the South Taylor Pit but not very <br />well defined for the East Pit, Facilities area and the Gossard Loadout. Please <br />include a detailed description of which seed mixes will be used to reclaim each of <br />the above listed areas. In addition to describing which seed mix will be used in the <br />above listed locations, Colowyo should consider providing a map that shows the <br />entire mine area and delineates which seed mix(es) will be used in which area of <br />the mine. <br />Rule 4.17 - Air Resource Protection <br />26. Permit Section 4.17 in the Colowyo permit does not contain any information <br />regarding the air resource protection measures at the Colowyo Mine. There are <br />references to other sections of the permit but there needs to be specific <br />information, in the form of text, in the performance standard section as well <br />(Section 4). Please include detailed information regarding the air resources <br />protection measures employed at the Colowyo Mine in Section 4.17. Please <br />reference the CDPHE-APCD air emissions permits in this section (including <br />permit number and expiration date). <br />Section VI - Bonding Summary <br />The Division currently holds bond monies, in the form of three corporate sureties, in the <br />amount of $83,156,939.00. The corporate sureties are in the amount of <br />$22,554,189.00 from Liberty Mutual Insurance Company, in the <br />amount of $10,752,595.00 from Liberty Mutual Insurance Company and <br />in the amount of $49,850,155.00 from Traveler's Casualty and Surety Company of <br />America. The Division recalculated the reclamation costs prior to proposing a decision <br />for Permit Renewal 05 (15 September 2009) and found the bond to be "sufficient to <br />assure the completion of the reclamation plan if the work had to be performed by the <br />Board, through independent contractors, in the event of forfeiture" (Rule 3.02.2(1)). <br />Equipment and seed costs have not been updated since this estimate was completed so <br />these costs are still valid. <br />This concludes the Division's 2010 Midterm Review for the Colowyo Mine. <br />Colowyo Mine <br />Permit No. C-1981-019 <br />2010 Midterm Review <br />10 May 2010 <br />16
