The Board notes that Rohm and Haas submitted its application for a revised permit on May 18, 
2007. Withdrawal at 2. Although Rohm and Haas refers in its withdrawal to issuance of the 
revised permit on January 14, 2007, the Board in light of the application date regards this as a 
merely technical error.
