Dear Mr. Schuh:

Requirements sheet is enclosed.
The Notice of Withdrawl of Petition is also enclosed. As was confirmed during a telephone
conversation between Paul Clark of our staff and yourself; CR Industries and the Division were able to
resolve issues pertaining to the adjudication during the March 27, 1997 meeting between Dave Goodrich
and Paul Clark of our staff and Larry Kagel and yourself. Thus, CR Industries has decided it would
withdraw its adjudication of the above-referenced permit upon receipt of the enclosed permit modification.
Please find enclosed the modified section of the permit referenced in the preceding paragraph.
Replace the original sections in your permit with the newer enclosed sections and discard the original
sections. All other terms and conditions contained in the original permit remain unchanged and in full
effect. These permit modifications are issued pursuant to the requirements of North Carolina General
Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
