FROM: M. J. Noland, Regional Superviso!'�"""i
Fayetteville Regional Office``
SUBJECT: Waste Load Allocation Request
E. I. DuPont De Nemours & Company
Fayetteville Plant
Bladen County
Fayetteville, North Carolina
The DuPont NPDES Permit (NC0003573) expired on June 30, 1982 and this
office has recommended that this permit be reissued with the same effluent
parameters until the new guidelines are promulgated. It is requested the
following limitations be deleted from the permit if they are not necessary
to protect water quality:
(1) Residual Chlorine (001)
(2) Fecal Coliform (001)
(3) Ammonia (001)
All discharges flow into the Cape Fear River Class C. Also, approxi-
mately 20,000 GPD of blowdown water from a water treatment plant should have
a separate discharge location (003).
It is the request of this office that a new waste load allocation be
initiated for the DuPont facility. Please remind Tech Services of the
proposed Rockfish Creek plant (6 MG initial, 12 MGD future) to determine
any interaction of waste streams.
If you have any further questions, please advise.
DEQ-CFW 00076519

SUMMARY
DuPont's NPDES Permit (No. NC0003573) expired on June 30, 1982. The
company has not exceeded production parameters of the former permit, and the
new Federal Guidelines are not finalized at this time for the Organic Chemicals
and Plastics and Synthethic Fibers Category. For these reasons, it is the
recommendation of this office that the DuPont permit be reissued based on
the previous staff report and effluent limitations (see attached). Should
the new guidelines be more stringent than existing effluent limits, then the
new guidelines will govern and the appropriate corrections made at that time.
The appropriate reopener clause should be included. An expiration date of
December 31, 1985 is recommended. February, 1985 is the projected date for
the establishment of effluent guidelines.
DuPont's wastewater treatment plant consistently produces a good quality
effluent which is discharged into the Cape Fear River, Class C. The effluent
quality is shown in the attached computer printout of DMR data for the period
March 1983 - April 1984.
This facilities' effluent limitations should be evaluated by the Technical
Services Branch for the following conditions to determine if they will protect
water quality standards.
1. With Jordan Reservoir, without Rockfish Creek
2. With Jordan Reservoir, with Rockfish Creek C6 MGD)
3. With Jordan Reservoir, with Rockfish Creek (12 MGD)
There is also the possibility that the Monsanto discharge (2.3 MGD) will
interact.
A static bioassay screen was run on the plant's effluent in January 1983
and it was determined that there was no appreciable toxicity associated with
this discharge.
It is recommended that this permit be reissued with the following changes:
1. Reopener clause
2. On page A(2) 002, Cooling Water, Effluent Monitoring Requirements
page, the 920F (daily average) and 1000F Cdaily maximum). temperature
parameter should be deleted. The ambient stream standard statement
should be sufficient.
3. The ammonia limitation A(l) 001, Process Water, Effluent Monitoring
Requirements page, should be deleted; however, this should be
monitored. It is our opinion based upon an evaluation done by the
Technical Services Branch that water quality standards can be pro-
tected without having a limit on NH3-N.
