West Elk Mine <br />conductors entering the underground mine have lightning arresters and are hung or adequately <br />protected against mechanical damage. <br />Employees trained to perform electrical work are certified for that type of work by the <br />appropriate State and Federal agencies. Except for troubleshooting, work is not performed on <br />energized electrical equipment. Thus, high voltage lines, both on the surface and underground, <br />are de -energized and grounded before most work is performed. <br />Accidents <br />MCC reports to the applicable State and Federal agencies all serious accidents damaging the <br />mine, the lands, or other resources that could cause air or water pollution. The agencies are <br />notified by telephone or in writing. At the samc time, MCC identifies any corrective actions <br />initiated to resolve the situation. <br />2.65-11 Rev. 11/04-PRII; 03/06 -PRIG; 07/15-MR413 <br />
