Subject: Permit Correction
NPDES Permit NC0003573
E.I. Dupont - Fayetteville Works
Bladen County
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,

The aquatic toxicity test using 24-hour composite samples of effluent discharged from Dupont De
Nemours has been completed. Dupont De Nemours has an effluent discharge permitted at 17 million
gallons per day entering Cape Fear River (7Q10 of 791.0 CFS). Whole effluent samples were collecttki
on March 4 by Paul Rawls for use in a chronic Ceriodaphnia dubia pass/fail toxicity test. The test t3
using these samples resulted in a pass, but these results should not be used for compliance mon oaring`
purposes. Toxicity test information follows.

This office has reviewed the request of DuPont to bypass the WWTP
with the Nafion HFPO Process Scrubber and Waste Gas Scrubber
discharges to the wood -lined ditch at the Fayetteville Works site.
n•
The data submitted indicates no appreciable pollutants of concert;
however this office concurs that a separate outfall should -be
established for toxicity and OCPSF monitoring as is currently d6he
on the WWTP discharge.
Should any toxicity test fail or OCPSF value show exceedence then
increased monitoring and a re-evaluation of the constituents of the
discharge should be required as a permit condition.
If you have any questions about this matter please contact me at

Use of Water Treatment/Biocide Products
NPDES No. NC0003573 (002)
Bladen County
E.I. Dupont - Fayetteville has submitted the following chemicals for approval: 1.) Bio-Trol 88P;
2.) Cor -Trot 778P; 3.) Balanced Polymer 54401; 4.) Opti-Meen; 5.) Continuum 41623; and 6.) Polymer
CDP -41788. Material Safety Data Sheets (MSDS), memos, and Biocide/Chemical Treatment
Worksheets - Form 101 have been reviewed and evaluated by Aquatic Toxicology Group staff.
Data submitted by E.I. Dupont concerning the dosage rate of Bio-Trol 88P, system volume, average
daily discharge, toxicity of the active ingredient and/or breakdown products, and minimum stream flow
have also been reviewed and evaluated. Calculations summarized on the accompanying worksheet
predict that the use of Bio-Trol 88 at the stated dosage rate and discharge conditions will not result in
toxic impact to aquatic life in the receiving stream. Therefore, the use of this product as a biocide at E.I.
Dupont - Fayetteville is deemed acceptable.
Compounds 2-6 do not appear to be, nor are they labeled as biocidal compounds and would
thus not require individual review and approval using the standard biocide review process. Since many
additives can affect the effluent pH, the discharge at this facility should be monitored. We performed the
attached calculations for Polymer CDP -41788 as if it were a biocide to address concerns we had
regarding toxicity of the active ingredient (aluminum sulfate). Calculations summarized on the
accompanying worksheet predict that the use of Polymer CDP -41788 at the stated dosage rate and
discharge conditions will not result in toxic impact to aquatic life in the receiving stream. Following
current permitting practices, the use of these compounds 2-6 should be allowable at E.I. Dupont -
Fayetteville.

RE: NPDES Permit No. NC0003573
Dear Sirs:
Attached is the DuPont -Fayetteville Works discharge monitoring report for November 1995.
The November 14, 1995, Outfall 001 sample was analyzed as 652 mg/L Total Suspended
Solids (TSS) which equates to 3,632 lb/day TSS versus the Daily Maximum permit limit of
950.1 lb/day.
That single daily exceedance resulted in a Monthly Average of 383 lb/day versus the permit
limit of 292.3 lb/day TSS.
We have instructed our commercial laboratory to return the remaining portion of this sample.
We intend to isolate the suspended solids and identify them, so that we can take the necessary
steps to prevent recurrence of this TSS exceedance.
If you have any questions regarding this matter, please feel free to call me at [phone].

SUBJECT: Plant Classification
E.I. DuPont, NPDES Permit NCO003573
Bladen County
We have reviewed the memorandum from Ron Ferrell of the Technical
Assistance and Certification Group and agree with their decision on removal of
the points for preaeration and sludge disposal. Although there is a
possibility of "super bug" addition, which would keep in place the Class IV
rating, it is our opinion that there is no justifiable need to pursue this
issue at this time. This is based on the compliant history of the facility and
questions over the real value of the extra data.
If you have questions or if we can be of assistance, please advise.

.0004 DEFINITIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physicallchemical method for reducing soluble organic material from wastewater effluent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upflow or�downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(2) Aerated Lagoons. A basin in which all solids are maintained in suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow-through basis;
(3) Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, agitation or diffusion;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agriculturally managed she. Any site on which a crop is produced, managed, and harvested (Crop includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium ton is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent limits;
