Dear Mr. Howard: a cL <
tx:
On August 13, 1995, Outfal1002 pH was measured as 3.6 St Xersu th ermitted minimum
of 6.0 SU. Two hours later, the Outfall 002 pH again droppeRd below ite minimum 6.0 SU
for 14 minutes, to a low of 5.9 SU. Both excursions were a result of the same incident.
The pH excursions were caused when the BCH Energy Project (Energy Generation Facility),
located on leased land within the DuPont site, experienced a release of approximately 12,800
gallons of low -pH water from their deminerialized water regeneration tank. This released
water flowed from the BCH facility onto the DuPont site, and ultimately into this site's non -
contact wastewater ditch which discharges through Outfall 002.
A written follow-up report dated August 15, 1995 from Metric Constructors, the construction
contractor for the BCH Project, was submitted to Mr. Michael Wicker of the DEHNR-DEM
Fayetteville Regional Office. In that report, Metric has outlined the corrective actions they,
have/will take to prevent recurrence of this incident.

E.I. DuPont & Co., Inc. - Fayetteville Works
Bladen County
Dear Mr. Johnson:
On November 12, 1993, the Division of Environmental Management issued permit number
NCO003573 to E.I. DuPont & Co., Inc. Based on your request received June 5, 1995, the language on
the supplement to the permit cover page now acknowledges boiler blowdown and once -through cooling
water from the BCH Energy Project at outfall 002. This permit modification becomes effective
immediately. Also, as previously discussed, approval of any biocidal compounds at outfall 002 is not
required since a whole effluent toxicity test is imposed on effluent for outfall 002.
All other terms and conditions in the original permit remain unchanged and in full effect. These m�
modifications are issued pursuant to the requirements of North Carolina General Statute 143-215 .l&nd?i4e
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection AgVy did
December 6, 1983. v 9
If this modification is unacceptable to you, you have the right to an adjudicatory hearing Qton
written request within thirty (30) days following receipt of this letter. This request must be in tlWo f
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with L
Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina 27604. UnlekV
such demand is made, this decision shall be final and binding.

RE: Modification of NPDES Permit No. NC0003573
Water Treatment Chemicals from BCH Energy Project
Dear Mr. Wicker,
Pursuant to 40 CFR 122.62(a)(1), this letter is a request for a
modification of the DuPont Company - Fayetteville Works' NPDES
Wastewater Discharge Permit to include water treatment chem cal=
from the cooling tower and boiler blowdowns from the BCH Ene gytc-,
Project located on leased property at this site, which willw
discharge through the DuPont permitted NPDES Outfall 002. ca
is r I cl ., res ",� '- to a
Znclosed is a check for $400.00 tb cover the co t of the pAmi .m
modification fee as required by NCAC Title 15A 2H.0105(b)(5).
The BCH Project's water discharge will be of like composition and
quantity of our existing oil -fired boilers, which will be idled
as a result of the successful start-up and operation of the BCH
Project.
However, there will be five commercial treatment chemicals used
by BCH in their cooling tower and boilers. A Form 101 for each
chemical is attached, which indicates that the concentration of
each chemical in the receiving water is well below the regulated
level. Therefore, we are requesting a permit modification to
Outfall 002 to include these five chemicals.
Our NPDES Permit is due for renewal on May 31, 1996. In our
renewal application, we plan to include analysis of Outfall 002
after the start-up of the BCH Energy Project so that the analyzed
effluent is representative of what can be expected during the
five year life of the permit.
