Doug Smith of Oxbow Mining accompanied the inspection. The weather was clear and dry. <br /> The status of the Elk Creek Mine, as far as the Division is concerned,is"Active"however no coal is being <br /> mined and the activity since the last inspection has been focused on the early stages of site reclamation. <br /> The MSHA status of the mine is"Temporarily Idled" <br /> BACKFILL and GRADING—Rule 4.14 <br /> Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); <br /> Steep Slopes 4.14.2,4.27;Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br /> Temporary pads had been constructed to allow for the dismantling of the conveyor. The currently <br /> approved reclamation plan specifies that the pads will be removed. It's possible that Oxbow may change the plan <br /> in the future, as business needs dictate,however this would require a revision. In the short term Oxbow plans to <br /> seed the pads. <br /> HYDROLOGIC BALANCE -Rule 4.05 <br /> Drainage Control 4.05.1,4.05.2,4.05.3; Siltation Structures 4.05.5,4.05.6; Discharge Structures 4.05.7,4.05.10; <br /> Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br /> Drainage—Acid and Toxic Materials 4.05.8;Impoundments 4.05.6,4.05.9; Stream Buffer Zones 4.05.18: <br /> Ditch maintenance was ongoing. The work to dismantle the conveyor and other facilities had temporarily <br /> impaired the surface water and sediment control system in a few spots,but not to the extent that off-site impacts <br /> would be expected. Oxbow should ensure that the site is returned to full compliance as soon as possible following <br /> the conclusion of the demolition projects. <br /> GENERAL MINE PLAN COMPLIANCE: <br /> There are no revisions in process. The mine site is being reclaimed in accordance with the plan. <br /> Number of Partial Inspection this Fiscal Year: 7 <br /> Number of Complete Inspections this Fiscal Year: 3 <br /> Page 2 of 10 <br />
