| 1.   | Two      (2) inactive disposal areas are known to exist at the nitrate plant leased      by Cherokee Nitrogen Company in Cherokee, Alabama.  The first      involves industrial waste disposed of in an on-site landfill located east      of the plant.  The landfill has been capped in excess of ten      (10) years and is covered with vegetation.  The second involves      approximately one hundred (100) tons of phosphoric acid tank sludge buried      directly east of the plant.  Material was generated from an old      phosphate plant that is no longer in existence.  The material      was buried prior to 1986.  Any liability associated with these      landfills is the responsibility of U.S. Steel, a prior owner of the      site. |

| 2.  | An      asbestos, construction debris, and elemental sulfur on-site landfill is      located at El Dorado      Chemical Company’s ammonium nitrate plant located in El Dorado, Arkansas.      The landfill was closed in 1995 under a state-approved closure      plan. |
