Following a three week outage, the site began to discharge treated wastewater from the temporary alkaline/
thermal treatment system to Outfall 001. Initial discharge would have been riverwater with very little BOD5 value.
The first five BOD5 results for Outfall 001 Indicated that quantities of BOD5 were being discharged In excess of the
permitted mass limits. DuPont feels confident that these results are in error either from the standpoint of Incorrect
analysis or sample misidentification. See attached cover letter.

The Outfall 002 BOD5 analysis for 02/19/01 was not a valid test because the depletion of dissolved oxvaen (D.O.) did
not satisfy the requirement of a minimum of 2 mg/L D.O. depletion, and therefore the laboratory reported the test
as being estimated, or less than, 118 mg/L BOD5, which was the analytical result with the greatest D.O. depletion.
The cause of this Invalid test was due to the laboratory Incorrectly Identifying the Outfall 002 sample as an Influent
sample and setting the dilution series for the expected high BOD5 results from the site's untreated influent
wastewater, -

on February 2, 2001, due to an unpermitted pollutant, hexafluoroacetone hydrate, which was
discovered in the WWTP. DuPont installed a temporary treatment facility to destroy the hydrate,
and on February 23, 2001, the site began to discharge from this temporary facility to Outfall 001.
As required by the DWQ authorization to operate the temporary facility, DuPont began
monitoring Outfall 001 seven days per week for BOD5, TSS, and Oil & Grease.
The analytical results for the Outfall 001 BOD5 samples for February 23 through
February 28, 2001, indicated a BOD5 daily mass discharge of 348, 230, 486, 669, >127, and
50.1 pounds respectively. This resulted in an apparent monthly average of 318 lb/day BOD5
versus a permitted limit of 191.3 lb/day BOD5. The discharge of 669 lb/day BOD5 on
February 26, 2001, exceeds the daily maximum limit of 508.2 lb/day BOD5. The BOD5 test
performed on the sample taken on February 27, 2001, depleted the dissolved oxygen in the BOD5
sample bottles to less than 1 mg/L, thereby invalidating that test.
DuPont is confident that the high BOD5 values reported on this DMR are not correct, however
we have been unable to find a definitive explanation for the error. It appears that the samples
that were analyzed during this period were actually untreated influent wastewater samples instead
of actual Outfall 001 composite samples. Unfortunately, we have not been able to determine how
such a sample identification error took place.
DuPont's claim that the analysis of the high BOD5 value water was not from Outfall 001 is
substantiated by the following information:
1. After the temporary alkaline/thermal treatment facility was constructed, it was filled with
riverwater to allow the project team to check out the operability and mechanical integrity of
the system. On 02/17/01, the project team began circulating the water through the system.

On 02/18/01, a sample of the water was analyzed internally with the result of no detectable
COD (less than 20 mg/L COD) and 2 mg/L TSS. On 02/23/01, water from the site's WWTP
was first introduced to the front of the alkaline/thermal treatment facility, thereby displacing
the riverwater in the system to Outfall 001.
Because this facility is comprised of twelve 20,000-gallon frac-tanks, interconnected with
piping, one would expect nearly plug flow of the liquid. Therefore, it would have taken
nearly twenty hours before the first amount of water from the site's WWTP to reach Outfall
001, which means that the entire flow through Outfall 001 on 02/23/01 was the riverwater
originally in the system. The analysis of the sample submitted as the Outfall 001 effluent for
02/23/01 indicated it contained 195 mg/L BODS, which is not consistent with either the COD
analysis of that water during the check-out period, nor with historical knowledge of the water
quality of the Cape Fear River.
2. During the period of the clean up of the site's WWTP, DuPont was sending its untreated
process wastewater to the two Fayetteville PWC wastewater treatment plants. PWC required
that DuPont submit to them a daily analysis of BODS, COD, and TSS of our influent
wastewater. For the month of February 2001, the influent BODS averaged 251 mg/L, with a
range of 118 mg/L to 362 mg/L BODS. The suspect Outfall 001 BODS analyses were all
within this range (see below). The normal BODS values for this site range from 5 mg/L to
15 mg/L, and usually the monthly DMR contains reported values of non -detect.

As indicated by this table, the samples analyzed for the dates from 02/23/01 through 02/27/01
would all appear to be influent samples. However, samples submitted as influent samples for
those dates also had reported BODS values in the range that would be expected for the
influent wastewater. Therefore, these suspect values cannot be explained as merely the
laboratory running the influent sample as the Outfall 001 sample and vice versa.

3. Additional analytical results taken of Outfall 001 samples during this period supports the
DuPont claim that the reported BOD5 values are incorrect. The DuPont ORC routinely
analyzes Outfall 001 for COD as an internal control sample to assist him in operating the
WWTP. Historically, the WWTP effluent has a BOD5 that is approximately 15% of the
corresponding COD value. During the period in question, the reported BOD5 values ranged
from 311% to 1225% of the ORC COD results. It is very unexpected to have COD values
that are less than the BOD5 value for the same sample.
Following the discovery of the suspect BOD5 values, DuPont asked that the commercial
laboratory run retained samples of Outfall 001 for both BOD5 and COD. These samples were
the remnants of the TSS samples for February, and had been stored in the laboratory's
refrigerator in darkness at less than 4°C. While these samples obviously exceeded the hold
time for BOD5 analysis, and did not have the required acidification for COD preservation, the
analytical results are very informative (see below).

Samples exceeded the hold time for BOD5 analysis and did not have a pH less than
2.0 SU as required by method protocol to preserve a COD sample.
While the Outfall 001 TSS samples greatly exceeded the hold time for a BOD5 sample, the
fact that they had been stored at a nearly freezing temperature and in darkness makes it highly
unlikely that subsequent biological degradation would have occurred to have dropped the
BOD5, in the case of 02/25/01, from 245 mg/L to <4.7 mg/L. Therefore, this information,
while not admissible on the February 2001 DMR, does support the DuPont contention that
the samples analyzed for BOD5 were not actually from Outfall 001.

DuPont has no explanation for these extremely unusual apparent BOD5 discharges. We
suspect that samples of the site's untreated influent wastewater were analyzed for BOD5 instead
of the Outfall 001 effluent, however we have no substantial evidence to support this claim. The
circumstantial evidence we can make reference to is the following:
• The first day of discharge (02/23/01) to Outfall 001 was completely riverwater that had
low measured amounts of COD and TSS, and could not have resulted in the 195 mg/L
BOD5 that was reported by the laboratory.
• The suspect Outfall 001 BOD5 results were all within the range of the influent BOD5
measured during that time.
• Further analyses of Outfall 001 resulted in COD values that were substantially lower than
the suspect BOD5 values, and analyses of retained Outfall 001 samples showed normal
levels of BOD5 during this period.
With regard to the apparent exceedance of the permitted monthly average, DuPont feels it is
mathematically incorrect to consider the reported monthly average to be a true indication of the
actual mass discharge average. The contentious issue here is the Division's disregard of periods
when there is no flow from a permitted facility. During the period beginning at 6:00 p.m. on
February 2, 2001, until 9:00 a.m. on February 23, 2001, there was no flow from Outfall 001, and
hence there was no BOD5 mass discharge from Outfall 001. DuPont's NPDES permit requires
three BOD5 samples per week, so during that period, seven BOD5 mass discharge determinations
should have been made. It is intuitively obvious that the mass discharge for those days was zero
(0) pounds per day. The only reason DuPont did not take a sample for BOD5 analysis during
those seven days is because there was no flow of treated wastewater to sample. If the seven
required monitoring days with 0 lb/day BOD5 discharge is considered, then the actual monthly
average for February 2001 would be 147 lb/day BOD5, which is well under the permitted limit.

Dear Sirs:
Enclosed is the DuPont — Fayetteville Works' Discharge Monitoring Report for February
2001. This rSport des an -additional DMR �aKe for Outfall 001 Ao report the s e6l
monitored earatnaters required by the DWQ Fayetteville Regional Office.
The discharge from the central Wastewater Treatment Plant (WWTP) a.athis sites w o stood
on Febrva due to an u.npermitted pollutant, hexafluoroacetorte'hydra* 4h was
discovered in the WWTP. DuPont installed a temporary treatment facility to destroy the hydrate,
and on February_ 23, 200.1, the site began to discharge from this temporary facili to Outfall 001.
As required by the DWQ authorization to operate the temporary facility, DuPont began
monitoring Outfall 001 seven days per week for BODS, TSS, and Oil & Grease.
The analytical results for the Outfall 001 130Ds samples for February 23 through
February 28=2001, indicated a BODs daily mass di Is arge of 348, B30, 486, 669, >127, and
S0. f pot►nds respectively. This resulted in an apparent monthly avera`e, of 318 lb/day BOD5
versus a permitted limit of 1.91.3 lb/day BODj. The discharge of °b9 lday BODE on
I ebrua OOL cods the dirily maximum limit of 508.2 lb/day BOD3. The Ds test
per ormed on the sample taken on Februaary 27, 2001, depleted the dissolved,ox i% BOD5
sample bottles to less than 1 mg/L, thereby invalidating that test. "
DuPont is confident that the high 13ODS values reported on this DMR Are not correct, however
we have been unable to find a defnitive`Rp anatron for the error. It appears that the samples
that were analyzed during this period were actually untreated influent wastewater samples instead
of actual Outfall 001 composite samples. Unfortunately, we have not been able to detennine how
