Dear Mr. Kennedy:
Your application for a NPDES permit modification to discharge an additional 0.40 MGD of
treated wastewater into the East Prong of Slocum Creek from a wastewater treatment facility
located on Jackson Drive in Havelock was received on July 15, 1991. Our Washington Regional
Office has performed a site investigation, and the Division has completed its review of the permit
application.
Our review has determined that the receiving stream designated by you has no natural flow
on at least seven (7) consecutive days during a ten (10) year period and at least thirty (30)
consecutive days during a two (2) year period. We refer to this stream as having zero 7Q10 and
30Q2 flow. Title 15A of the North Carolina Administrative Code, 2B .0206 (d) (2), specifically
prohibits new or expanded discharges under such flow conditions.
After thirty (30) days from receipt of this letter, this Division will send your permit
application to public notice stating our intent to deny your NPDES permit modification request
unless you withdraw your request for an NPDES permit by requesting a project return. If you
wish to withdraw your request for a NPDES permit, you may do so by stating that desire in a letter
to our office. Your letter must be received by our office within thirty (30) days of your receipt of
this letter. The City should continue investigating alternatives other than discharging into the East
Prong of Slocum Creek. The Division strongly encourages the City of Havelock to pursue a
regional treatment facility with the Marine Corps Air Station or other local municipalities or units of
local government.

(approach taken, correspondence with region, EPA,etc.)
Recommend denial of expansion per zero flow policy. Additionally, there are localized water
quality problems including stratification, anoxic conditions, and algal blooms in Slocum Creek.
Havelock did its own monitoring survey in 1988 which confirmed the poor water quality. The city
was told by letter in 1987 and 1989 that expansion at the current site was not recommended.
The city is also having difficulty with its toxicity testing. Have failed about half its tests this year.
In the future, metals limits will be required.

a . Classification: "C" Swamp
b. River Basin and Subbasin No. : 03-04-10
C. Describe receiving stream features and pertinent
downstream uses: Used for fishing, boating
and drainage. There is a 3 . 5 MGD discharge from
Cherry Pt. several miles down stream.
PART II -- DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1 . Type of wastewater: 100o Domestic
a . Volume of Wastewater: 1 . 5(existing) MGD (Design
Capacity) 1 . 9(proposed) MGD
b. Types and quantities of industrial wastewater:
N/A
C. Prevalent toxic constituents in wastewater:
Process concentrates groundwater with some
additives . N/A
d. Pretreatment Program (POTWs only) : N/A
In development Approved
Should be required Not needed
3 . Type of treatment (specify whether proposed or
existing) : Existing 1 . 50 MGD facility consisting of
preliminary treatment (bar screen and grit removal )
followed by a contact stabilization process including
aeration , clarification, reaeration, followed by
nitrification basins followed by a final clarifier for
sedimentation. The wastewater then flows through a
chlorine contact basin for disinfection followed by a
reaeration basin.
However the facility proposes 1 .9 MGD facility
consisting of preliminary treatment followed by
primary clarifiers for sedimentation followed by a
. biological process (anaerobic, anoxic and aerobic
units) , activated sludge for carbonaceous and nutrient
removal . The biological process would be followed by
secondary clarifiers and filters then disinfection
in the chlorine contact basin followed by reaeration.
4 . Sludge handling and disposal scheme: The sludge will
be treated by lime stabilization and land applied on a
permitted site .
5 . Treatment plant classification: (Less than 5 points no rating; include rating sheet, if appropriate) .
Class IV

� 6 . SIC Code(s ) : 4952
Wastewater Code( s ) : Primary 01
PART III -- OTHER PERTINENT INFORMATION
1 . Is this facility being constructed with Construction
Grant Funds (municipals only) ? No
2 . Special monitoring requests :
3 . Additional effluent limits requested:
4 . Other:
PART IV -- EVALUATION AND RECOMMENDATIONS
Havelock Wastewater Treatment facility request these
modifications of upgrade to meet the nutrient and
phosphorus limitations that will take effect January 1993 .
Also included is an expansion fron 1 . 5 MGD to 1 . 9 MGD.
The receiving stream has a 7-day 10-year low flow of zero.
Therefore the City should be requested to show that there
is no other feasible alternative to discharge in a zero
flow stream.
