Industrial User Pretreatment Permit Number 0001
(SIU in the Town of Pittsboro, NC0020354)
Chatham County
Dear Mr. Isaacson:
An Industrial User Pretreatment Permit (IUP # 0001) modification was transmitted to you in a letter dated
June 23, 1998. As you discussed with Dana Folley of the Pretreatment Unit, there were two errors in that
transmittal package. First, the typographical error on page 4 of the IUP had not been corrected. Attached
please find a corrected page. Please discard the original page 4 and replace it with this corrected page.
Additionally, a copy of a draft Notice of Violation was attached to the IUP. Please remove and discard this
draft. We regret any inconvenience and will make every effort to correct our file copies of our original
submission.
Thank you for your cooperation with the Pretreatment Program requirements. If you have any questions,
please call Dana Rees Folley of the Pretreatment Unit at [phone] (ext. 523), or Tom S. Poe,
Pretreatment Unit Supervisor (ext. 522).
Sincerely,
S P�
Preston Howard, Jr., P.E.
