Subject: Implementation of Middle Cape Fear River Basin Association
NPDES Permit Modification for Instream Sampling
Permit NC0003573 DuPont - Fayetteville Plant
Cumberland County
Dear Mr. Johnson:
As a participant in the coordinated instream monitoring efforts within the Cape Fear River basin, your facility
entered into an agreement with the North Carolina Department of Environment and Natural Resources (NC
DENR) that provides both parties with an effective environmental monitoring tool. By this letter, NC DENR is
waiving the instream monitoring requirements specified within the subject permit as of September 1, 1998. The
Memorandum of Agreement (MOA) signed by NC DENR and you (or your representative) identifies the revised
stations, parametric coverage and frequency of analysis required for your facility.
All other terms and conditions contained in the original permit remain unchanged and in full effect. This
permit modification is issued under the requirements of North Carolina General Statutes 143-215.1 and the
Memorandum of Agreement between North Carolina and the U. S. Environmental Protection Agency dated
December 6, 1983 (and as subsequently amended). Should your membership in the MOA be terminated, the
instream monitoring requirements specified in the subject permit will be reinstated. You shall notify the Division
immediately upon termination of membership.
I would like to express my gratitude for the cooperation of all participants in this innovative approach to
environmental monitoring. It is expected that the results of the agreement will effectively contribute to our
understanding of the Cape Fear River Basin ecosystem. We have designated Cathy Tyndall as our primary
contact for issues related to the MOA. She can be reached at [phone].
We also look forward to the advances that this cooperative agreement will provide in our management of the
Cape Fear River Basin. We encourage you to contact us should any questions arise regarding the monitoring
efforts or interpretations of the information collected. We will maintain our own series of monitoring stations in
the basin which (when added to the data collected under this MOA) will greatly expand our knowledge of this
ecosystem. We thank you again for your participation and look forward to a successful monitoring effort.

Pursuant to Part III(C)(a) of the referenced NPDES permit, DuPont — Fayetteville Works is
required to notify the Division of Water Quality of a planned activity which would result in the
routine discharge of a toxic pollutant, not limited in the permit, which would exceed 100 µg/L
concentration in the treated effluent.
This site is planning to install a water scrubber to comply with the requirements of the
Printing and Publishing NESHAP as codified in 40 CFR 63 Subpart KK. The scrubber will
remove dimethyl formamide (DMF) from the exhaust vent of the Butacite® Tinting Process, and
the effluent from the scrubber will be biologically treated in the site's Wastewater Treatment
Plant (WWTP). The treated wastewater will be discharged through Outfall 001, which does not
have a permit limitation for DMF.
The maximum potential DMF scrubbed out of the exhaust vent would be 218 lb/day. We
anticipate that most of the DMF would be biologically degraded. However, if all 218 lb/day of
the incoming DMF were discharged from the WWTP, the maximum DMF concentration at
Outfall 001 would be approximately 29 mg/L.
Dimethyl formamide is not one of the priority pollutants listed as part of the Clean Water
Act, therefore I do not believe that a specific numerical limitation needs to be established.
I trust that this letter satisfies the notification requires specified in the referenced NPDES
permit. If you have any questions, please feel free to call me at [phone].

Pursuant to Part III(C)(a) of the referenced NPDES permit, DuPont — Fayetteville Works is
required to notify the Division of Water Quality of a planned activity which would result in the
routine discharge of a toxic pollutant, not limited in the permit, which would exceed 100 Rg/L
concentration in the treated effluent.
This site is planning to install a water scrubber to comply with the requirements of the
Printing and Publishing NESHAP as codified in 40 CFR 63 Subpart KK. The scrubber will
remove dimethyl formamide (DMF) from the exhaust vent of the Butacite® Tinting Process, and

Plant (WWTP). The treated wastewater will be discharged through Outfall 001, which does not
have a permit limitation for DMF.
The maximum potential DMF scrubbed out of the exhaust vent would be 9.1 lb/day. We
anticipate that most of the DMF would be biologically degraded. However, if all 9.1 lb/day of
the incoming DMF were discharged from the WWTP, the maximum DMF concentration at
Outfall 001 would be approximately 1.2 mg/L.
Dimethyl formamide is not one of the priority pollutants listed as part of the Clean Water

Section D• Summary of Findings/Comments:.

1. Mr. Hall produced a copy of the current NPDES permit when asked. It is suggested that all
staff associated with the day to day operation of the wastewater treatment facility read the
permit periodically.
2. _ Aqua Tech and Burlington Laboratory performs the "outside" permit required analytical work
for the facility.
3, A log of daily operations was reviewed. The 1--:, is maintained in a manner that allows staff
to develop trends and determine necessary ops ational modifications to insure compliance.
The facility is maintained at a MLSS of about '.-:.X00 mg/l, a F to M of 0.13. MCRT is about
31 days and average D.O. (aeration basin) is -sorted to be 6.4.
Phosphoric Acid and Ammonia (NH3) is inti.., ad in the aeration basin to maintain proper
biological activity. Polymer is introduced in �-: :: iarifiers to aid in settling. Defoamer is used
when necessary.
Trends and all modifications to the operational scheme -should be recorded in order to
develop a basin line of data to assist when the inevitable upset occurs. The staff should be
commended in keeping this data in such a user friendly manner.
4. A limited spare parts inventory is maintained at the facility. It is strongly suggested that this
inventory is reviewed at least annually to. determine such items as local availability, order/
delivery time, age of currently utilized components and overall history of service for each key
component of the wastewater treatment facility.
5. On the day of inspection, the effluent appea:•3 d to clear and free of excessive solid.
6. DMR and laboratory data agree for discharge pipe .001 for September 1997 (spot check).
It was noted that monitoring for OCPSF parameters revealed no concentrations above
detectable levels for the data reviewed.
7. Sludge (residuals) is processed utilizing a "DAF" unit, sludge holding tank, sludge press and
dryers. It is delivered to "BFI" landfill site located near Roseboro, Sampson County for
disposal.
8. Based on information obtained during the inspection all wastewater staff have been trained
in Confined Space entry techniques.
