RE: Illinois Central Spring

April 12, 1999

Thank you for meeting with the United States Environmental Protection Agency ("U.S. EPA") regarding the above-referenced site on March 25, 1999. As CBS Corporation ("CBS") was informed, U.S. EPA has completed its design of the water treatment plant for the site, and has more accurately determined the plant's cost. CBS was informed that the cost of the plant, as designed, is now greater than the cost estimated at the time of the action memorandum. U.S. EPA is now completing site-preparation work, and will soon start construction of the water treatment plant. As we discussed, U.S. EPA extends to CBS the opportunity to take over work at the site, assuming that CBS can implement U.S. EPA's design and complete construction in accordance with U.S. EPA's schedule. As CBS was informed, there are limited lead times for ordering some of the materials needed to equip the plant and meet the site-cleanup construction completion target date. Accordingly, CBS should timely advise U.S. EPA whether CBS is interested in entering an administrative order on consent with U.S. EPA.

Please contact me if you have any questions or comments regarding this matter.
