Subject: Permit Correction
NPDES Permit NC0003573
E.I. Dupont - Fayetteville Works
Bladen County
Dear Mr. Mayberry:
On July 25, 1996, the Division of Water Quality issued NPDES Permit No. NC0003573
to E.I. Dupont de Nemours & Co., Inc.. The mass limits for the OCPSF priority pollutants at
Outfall 001 were not revised for a process flow of 0.948 MGD even though the cover letter stated
they were. These figures are now based on the process flow of 0.948 MGD. Please insert the
enclosed pages and discard the old sheets. This correction becomes effective on the effective date
of the permit.
All other terms and conditions in the original permit remain unchanged and in full effect.
These modifications are issued pursuant to the requirements of North Carolina General Statute
143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated December 6, 1983.
If any parts, measurement frequencies or sampling requirements contained in this
correction are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. This request must be in the form of
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina
27604. Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning this permit, please contact Mr. Greg Nizich at telephone
number 919/733-5083, ext. 541.
Sincerely,
C . .4% '�
