Subject: Issuance of NPDES Permit NCO021849
Hertford WWTP
Perquimans County
Dear Mr. Christensen:
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we
are forwarding the attached NPDES discharge permit. This permit is 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 May 9, 1994 (or as subsequently amended).
This final permit includes one major change from the draft permit sent to you on October 30, 2002:
Monitoring frequencies for the 0.7 MGD flow have been revised to Class III frequencies. The Washington Regional
Office informed the NPDES Unit that upon expansion the Hertford WWTP will be rated a Class III facility.
The Division is currently in the process of implementing a Water Quality Standard for Total Residual Chlorine (TRC)
and expects to introduce permit limits statewide in April 2003. Although TRC is not currently limited in this permit at
0.4 MGD, the Division recommends that you prepare a budget and schedule construction of facility upgrades to
restrict the discharge of TRC (or explore alternative methods of disinfection). Future renewals of this permit will
include a TRC limit of 28 µg/L, regardless of whether expansion to 0.7 MGD has been completed.
If any parts, measurement frequencies or sampling requirements contained in this permit 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 (6714 Mail Service Center, Raleigh, North Carolina
27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain
other permits which may be required by the Division of Water Quality or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Charles Weaver at telephone number (919)
733-5083, extension 511.
Sincerely,

To: stephen lane <[e-mail]>
Stephen, in your staff report for this renewal you recommended that the
permit be issued with Class III monitoring for the expansion phase.
I'll make the change to the 0.7 MGD effluent page.
I'm ready to finalize the permit, so let me know if there are any other
changes you'd like made. I've attached an electronic copy of the draft
permit.

PART IV - EVALUATION AND RECONNENDATIONS
The facility is currently operating under EMC SOC WQ01-007. The
facility is at times receiving flow at a rate greater than what
the plant was designed to treat. The flow, BOD, TSS, and fecal

process of upgrading the facility to 0.7 MGD. The progress on the
upgrade is approximately one year behind schedule and Al Hodge of
the Washington Regional Office has consulted with town
officials regarding modifying the completion time schedule in the
existing SOC for the facility upgrade. It is recommended that this
permit be reissued with appropriate monitoring schedules for a
Grade III facility upon completion of the expansion project.

SUMMARY
The Town of Hertford is currently to operate its WW I'P at 0.4 MGD, with a phased expansion flow of 0.7
MGD. The Town is currently operating under an SOC while it arranges for funding and approved plans for
the expansion. This facility is 100% domestic with no pretreatment program.
The discharge goes into the Perquimans River in the Pasquotank River basin. The Perquimans River is not
on the 303(d) list.
COMPLIANCE SUMMARY:
Per the data in BIMS (see attached computer printout), Hertford's WWTP regularly violates flow and is
discharging large amounts of Total Residual Chlorine (TRC). No other severe compliance problems were
noted. Data for the period January 2000 — August 2002 was reviewed
INSTREAM MONITORING:
Hertford is not required to perform localized monitoring at the 0.4 MGD flow. Instream monitoring will be
required upon expansion to 0.7 MGD.
PROPOSED CHANGES:
➢ Instream monitoring for fecal coliform will be deleted from the 0.7 MGD flow, per policy for 100%
domestic discharges below 1 MGD. The facility has not displayed any compliance problems with
fecal coliform during the period January 2000 — August 2002.
➢ A weekly average ammonia limit will be included at the 0.7 MGD flow, per the revised ammonia
policy.

The Town of Hertford has entered into an agreement with Granville Farms,
Oxford, North Carolina to land apply wastewater residuals generated at their wastewater
treatment plant. This facility produces a Class B — lime stabilized material which meets
both pathegen and vector requirements.
The process consists of aerobic sludge digestion and storage, transfer pumping,
tanker hauling, and terragator injection of residuals onto 291 acres of town permitted land
in Perquimans County, North Carolina. Hauling volume and frequency is approximately
60,000 gallons per 6-week cycle. Annual volume is estimated to be 500,000 gallons.
The Town continues to maintain their sludge drying beds for emergency storage.
Residuals from these beds is disposed of at the County landfill.
