Dear Mr. Freeman:
The Division of Water Quality (the Division) hereby issues this permit final for the subject facility. 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 October 15, 2007, or
as subsequently amended.
For changes to the previous permit, see the Draft Permit cover letter. The Division acknowledges your
written comments on the draft, received on June 30. We offer the following corrections and responses to
comments.
1. Revised the Supplement to Cover Sheet to reflect your corrections to facility components;
2. Updated map and text to reflect discharge to McCotter Canal, hence to Shop Branch
[Stream segment 27-115-3], a tributary to Hancock Creek;
3. Corrected Longitude from 78 degrees to 76 degrees on map and in text;
4. Because your facility is among the least significant sources of nutrients to the Neuse River
estuary, and is therefore least likely to receive Total Nitrogen (TN) or Total Phosphorus
(TP) permit limits in the foreseeable future, the Division has reduced your monitoring
requirements for these parameters from 1/Month to 1/Quarter.
5. Revised the draft permit flow limit, per your request, from 0.165 to 0.360 MGD;
6. Added footnote [see Section A. (1.) and (2.)] providing for a future request, to modify
monitoring conditions for specific parameters, as warranted see Section A. (1.), Footnote 3];
7. Deleted fluoride from the permit because, a) you do not add fluoride to drinking water,
i.e. to filter -backwash water; and b) there is no saltwater instream standard or criteria for
fluoride against which to evaluate future reasonable potential to exceed.
8. Corrected WET Testing requirement to reflect "composite" sampling, based on flow >0.030
MGD and discharge to "tidal saltwater, not modeled" (24-hour Acute Pass/Fail @ 90 %) in
accordance with the WTP Guidance 2007. Attached Section A. (3.) inadvertently missing
from the draft.

Footnotes:
1. E = Effluent; I = Influent; U = upstream at least 50 feet from the outfall; D = downstream at least 50 feet from the
outfall.
2. TRC - Because low-level TRC is currently difficult to quantify in a wastewater matrix, the Division shall consider
all effluent TRC values reported below 50 µg/L to be "in compliance" with the permit. However, the Permittee shall
continue to record and submit all values reported using North Carolina -certified field and lab test methods, even if
these values fall below 50 µg/L.
3. Modifications - After one year, (12 samples minimum), the Permittee may petition the Division to reevaluate the
monitoring requirements for a given parameter. If new data warrant, the Division may modify the permit and may
consider this a minor permit modification.
4. For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen, and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively.
5. Whole Effluent Toxicity (WET) testing - Pass/Fail @ 90%, monitor only [Jan, Apr, Jul, Oct -Pem» ace's choice
of species: fathead minnow; silverside minnow; mysid shrimp, See Section A. (2.)].
The Permittee shall collect and report only those samples that accurately represent the discharge. The Permittee
shall discharge no floating solids or foam visible in other than trace amounts.

Permit NCO078131
A. (2.) ACUTE TOXICITY - MONITORING ONLY (QUARTERLY)
The Permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration" (Revised-July,1992 or subsequent versions). Choice of Species: fathead minnow, silverside
minnow, or mysid shrimp. Monitoring shall be performed -as a 24-hour static test. The effluent concentration at
which there may be at no time significant acute mortality is 90 % (defined as treatment two in the procedure
document). Effluent samples for self -monitoring purposes must be obtained during representative effluent
discharge below all waste treatment. The tests will be performed during the months of January, April, July
and October.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGUE.
Additionally, DWQ Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made. The Permittee shall submit test data that is
complete and accurate and include all supporting chemical/physical measurements performed in association with
the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the Permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at
the address cited above.
Should the Perimittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to
include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
follow-up testing to be completed no later than the last day of the month following the month of the initial
monitoring.

Dear Mr. Corporon:
Thank you for sending the Draft Permit for the above referenced facility. As requested we have
reviewed the draft for both completeness and accuracy. We present our specific comments
below.
Page 1 No change
Page 2 item 1 suggested language
1. continue to operate the Brown Boulevard WTP to produce potable water and associated

from the facility located at the intersection of Brown Boulevard & Webb Boulevard
in Havelock, Craven County, and

A. (1) Effluent Limitations and Monitoring Requirements
The flow should be revised to 0.36 mgd (Based on the rated plant flow of 2.8 MGD times the
historical peak monthly average backwash rate of 0.127 MGD per MGD of finished water). This
is necessary to assure there is adequate discharge capacity as the existing water plant approaches
the design capacity and may avoid a future permit modification. The City's decision to commit
public resources and construct this water plant capacity was made well in advance of there being
a flow limitation on the wastestream.
For conductivity and salinity, often the conductivity is measured and converted to salinity. We
suggest we measure both for one year (12 samples), evaluate the correlation and then if
appropriate, use the conductivity measurements to also determine salinity.
As recommended in the September 2007 guidance document "NPDES Permitting Strategies for
Potable Water Treatment Plants" (Guidance Document), for the metals, we suggest the monthly
monitoring proceed for one year, the data be evaluated and if appropriate, the sampling be
reduced to quarterly. The quarterly sampling would focus on the worst month in the quarter.
Also as recommended in the September 2007 Guidance Document, fluoride monitoring should
only be implemented if a fluorinated finished water is used for backwashing the filters and
softeners. Because the subject treatment plant does not add fluoride to the water, it appears the
fluoride monitoring requirement is not necessary and hence we request it be deleted.
For Whole Effluent Toxicity (WET) the sample should be a 24 hour composite to more
accurately represent the daily discharge. This is also in accordance with the Guidance
Document.

Page 5
A. (2) Receiving -Stream Monitoring
The comment on salinity and conductivity on page 4 also apply here, with one year's data being
used to establish the correlation between conductivity and salinity and if conductivity will be
used to also measure salinity. This would allow all measurements to be collected in the field.
Thank you for considering our comments. After the inclusion of the comments in the draft
permit, we respectfully request an opportunity to review the changes. Of course we are available
for a meeting to resolve any concerns. We look forward to working with you and your staff
toward developing a permit that is both fair to Havelock and environmentally protective.

FACILITY RECORDS REVIEW
Facility Description. The permittee operates a Water Treatment Plant (WTP) designed to produce
potable water at a maximum rate of 2.8 million gallons per day (MGD), generating 0.900 to 0.100 MGD
of filter backwash wastewater. This facility utilizes ion -exchange technology and manganese -based
"green -sand" filters. This system also utilizes water softeners. Filter backwash wastewater is collected in a
settling basin where the supernate discharges to surface waters of the state.
Verifying Existing Stream Conditions. This facility discharges to McCotter Canal and hence to
Hancock Creek [27-115], a Class C-SW; NSW waterbody within the Neuse River Basin. Based on the
permittee's treatment technology, the Division does not anticipate that this potable water process will
generate significant quantities of nutrients.

PERMITTING APPROACH
Site Facility Map has been revised and Outfall 001 location has been updated.
Ion Exchange and Greensand Filter Systems. The Division herein prescribes limits and monitoring
deemed appropriate for ion exchange, water -softening, and manganese "greensand" treatment processes
according to recent NPDES guidance for water treatment plants (revised September 2007). This facility
shall therefore monitor flow (limit at 0.165 MGD), Total Suspended Solids (TSS), Total Iron, Total
Manganese. The Division will also add Ammonia Nitrogen (NHA Chloride, Total Copper, Total Lead,
and Total Zinc as contaminants of concern (COCs) due to their presence as target filtrates. Fluoride will
also be added to establish a database for future monitoring adjustments.
In addition, others parameters are specifically required for nutrient -sensitive waters (NSW) within the
Neuse River Basin. This renewal includes updated nitrogen and phosphorous requirements (see permit
Section A. (L). Although Total Residual Chlorine (TRC) is limited at 13 µg/L (SC waters), the Division
has added a footnote stating that, because of present difficulties in quantifying low-level TRC in a
wastewater matrix, values reported below 50 ug/L will be deemed "in compliance" with the permit.
Whole Effluent Toxicity (WET). This Ion -exchange system discharges to saltwater (Sc) influenced
by ocean tides and has not been modeled, therefore WET testing is required (Acute 24-hour Pass/Fail
@ 90 %), according to the 2007 WTP Policy.
Residual Solids Management Plan. The Permittee's removes residual solids from the WTP and
transports them to the Havelock W WTP where sludge is dried. Sludge is then loaded and transported for
disposal to the Tuscarora Landfill in Craven County.

City of Havelock Water Treatment Plant Backwash Systems (Short Form C)
Craven County
Dear Mrs. Sprinkle,
The City of Havelock herein submits a permit application form for the City's Water
Treatment Plant Backwash System. This facility has undergone some
improvements/expansion since last permit renewal. The expansion consisted of an
increase in the maximum output of the plant to 2.8 MGD, and daily output of 1.28 MGD.
A ten -inch well, with the capabilities of delivering up to 1000 gpm, was added for a total
of four wells. Three more filters and two more softeners were added to the treatment line,
and during this time the method of disinfection was changed to chloramines, from free
chlorine. Also during this time, the City decommissioned its oldest treatment plant
(Lynnwayne). Lynnwayne was decommissioned due to the extensive repairs needed to
the facility, so the Webb plant was expanded to shoulder the City's water demand.
The backwash flow has been averaging 96,000-100,000 gallons per day. A copy of our
sludge management plan is enclosed. If you need any further information, please do not
hesitate to contact me at (252)-444-6420.

6. Description of source wates(s) (Le_ groundwater, surface water)
Castle Haynes Aquifer(groundwater)
?. Describe the treatment process(es) for the raw water.
Water from the Castle Haynes aquifer is pumped up from our wells to aeration basins,
where the cascades down through gnItm, thus remov" - any hydrogen sulfide that may
be in there. Then pumps take it from the basin, while being injected with potassium
permanganate to the 6 filters, the water, then goes through the gmeasand f0ters and
catches the iron , now soluble form. The water then leaves the filters and goes to the ion
exchange softeners that remove the calcium and maganesivan. After the softners the water
is blended With filter water to achieve the proper hardness, then is injected with zinc
orthophosphate for corrosion control, then with hypochlorite bleach, then finally with
ammonia to form chlorornines. After the chemical injecI ts the water goes to a 1.0 MG
storage tank, then pumped to the system.
S. Describe the wUM Ee-eater and the treatment pa vess(es) for w t e -m ester generated by the
facility:
The wastewater is water from our filter backwash, which mainly is iron and a little
manganese. The water used for backwash is. wed water consiting of chlorominated
water. The other part of the wasteevater is from our softeners, which uses filtered water
and a brine solution for recharging the soitsaers. The water is discharged to our waste
holding basin, where it is held ior the proper settling time to achieve good, clear effiuent.

City of Havelock's WTP Waste Management Plan ;.;
The City of Havelock's WTP manages the sludge produced from backwash water in the
following manner. Annually, or when the sludge level in the backwash catch basin
reaches a level of two feet, a vacuum truck is used to remove the sludge and transport it
to the Havelock WWTP, where it is deposited in a dump pan. Once in the pan the sludge
is allowed time to settle and the clear water is drained to the -head of the WWTP. When
the sludge is dry enough to pass a paint filter test it is loaded and transported to the
Tuscarora Land Fill in Craven County.

YES_ This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes).
YES ✓ This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan),
Conventional WTP, 303(d) listed, toxicity testing, instream monitoring,
compliance concerns, phased limits). Basin Coordinator to make case -by -
case decision.
YES_. This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS, etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
