For the 12-month period ended December 31, 2011, none of our operations received
written notice from MSHA of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards
under section 104(e) of the Mine Act. On November 30, 2011, we were notified that a potential pattern of violations existed at the No 58 mine, MSHA ID # 46-08884, under section 104(e) of the Mine Act. Following that notification, we implemented
a corrective action program to reduce the number of violations cited at the mine. On March 15, 2012, upon review of the progress of the corrective action plan, MSHA concluded that a potential pattern of violations does not exist at the No 58
mine.
