i. Monthly TN Load (lb/mo) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/L) of the composite
samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the December
report for that year.

A. (5.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February
1998) or subsequent versions. The tests will be performed during the months of January, April, July and October.
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below
all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are specified
in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B
for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to
be sent to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. 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 Branch at the address cited above.
Page 6

Permit No. NC0021253
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month.
Should any test data from this monitoring requirement 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 ate 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, minimum control organism reproduction, 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.

SUMMARY
Havelock WWTP receives domestic wastewater from the City of Havelock, and serves - 14,000
local residents. No major changes have occurred at the treatment plant since the last permit renewal.
The receiving stream can't support any increase in the discharge due to the poor water quality
conditions and lack of assimilative capacity. The City was advised by DWQ that any expansions
above 1.9 MGD would require a relocation of the discharge to the Neuse Rive.
INSTREAM MONITORING
This facility is a member of the Lower Neuse Basin Association. Due to the absence of the upstream
monitoring station on the Slocum Creek it is difficult to evaluate effect of the facility on the
receiving stream.
RPA
Reasonable potential analyses (RPA) were conducted for Cu, Ni, and Zn. Please see attached.

TOXICITY TESTING
Chronic P/F @ 90% at 1.9 MGD using Ceriodaphnia.
No change to the toxicity testing condition is recommended at this time. The facility passed all
whole effluent toxicity (WET) tests for the period of review (2004 — 2008) except July 2005. The
subsequent test passed.
COMPLIANCE SUMMARY
A review of the facilities compliance data indicates mixed performance. There were four NOVs
issued during the review period (2003-2008): 01/25/08- NH3 and TP, 09/13/05 — Tox. test, 07/06/04 —
flow, 08/21/03 — flow.
NITROGEN
The Environmental Management Commission adopted Nutrient Management Strategy rules in
December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point
source rule (T 15A NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point source
dischargers larger than 0.5 MGD.
The rule also allows dischargers to form a group compliance association and work together to reduce
nitrogen; this option allows the association members added flexibility in controlling nitrogen
discharges. At the same time, the association is subject to a group NPDES permit ensuring that the
association and its individual members are accountable if they exceed the applicable nitrogen limits.
Under the rule, there are three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association permit.
A discharger maybe subject to the first type of limit, or to the second and third, but never to all three
at the same time. The discharger is first subject to the TN limit (if any) in its individual NPDES
permit. If becomes a co-Permittee to a compliance association's group NPDES permit, it is then
governed by the TN limits in that permit. If the association complies with its group TN limit in a
given year, all members are deemed to be in compliance with their individual allocations/ limits in
the group permit. If the association exceeds its limit, the members then become subject to their
individual allocations/ limits as well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over time
as the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division
will modify the affected permits as necessary to ensure that the limits are kept up to date and.reflect
any such transactions.
Under the new rule, the Town receives a TN Load limit of 21,400 lb./yr., a calendar year limit. This
limit will be calculated annually. In addition to this limit, the Permittee will be required to report
total monthly flow, total Kjeldahl nitrogen and the sum of nitrate and nitrite in addition to the
existing requirement to report monthly total nitrogen concentrations and loads.
The Town is a member of the Neuse River Compliance Association at this time. So long as it
remains a co-Permittee member, it is deemed to be in compliance with the TN limit in this permit,
and its TN discharge is governed instead by the Association's group NPDES permit, issued
December 30, 2002.

MANAGEMENT PLAN
The residual solids management plan describes the process by which the residual solids from the City of
Havelock will be land applied to permitted acreage as an agricultural resource at agronomic rates. The
residual solids will be applied to row crops, coastal bermuda and fescue for hay production at
agronomic rates for total or partial replacement of conventional nitrogen (N) and phosphorus (P)
fertilizers. The actual amount of residual solids applied will be dependent . upon the nutrient
requirement of the specific crop and the nutrient content of the residual. solids.
Residual solids application scheduling will ,be dependent upon residual solids production, storage at the
respective treatment plant, and the crop management program. On fields utilized for hay production,
residual solids will be applied in split applications as is normally done when conventional fertilizers are
applied to hay land. These applications will correspond prior to grass growth in the spring, after each
cutting in the growing season, or whenever most appropriate. On fields utilized for row crops, residual
solids will be land applied between crop rotations.
The fields will receive residual solids in an agronomic manner based on requirements listed in the
permit. Residual solids will be applied at agronomic rates which are limited by nitrogen loading rates.
An acceptable pH will be maintained in the soil, residual and lime mixture greater than 6.0 on all land
application sites with mineral soils to insure optimum yield for the crop being grown.
Prior to an application event, an application rate will be determined based on a current residual solids
nutrient analysis. Representative residual solids samples will be collected prior to the haul period and
composited for analysis. This composite sample will then be delivered to a qualified laboratory familiar
with residual solids analysis and analyzed for ammonia nitrogen, nitrate/nitrite nitrogen, percent total
solids, total Kjeldahl nitrogen, phosphorus, potassium, calcium, magnesium, sodium, arsenic, mercury,
selenium, molybdenum, chromium, copper, zinc, cadmium, nickel, lead, aluminum, and pH. Plant
available nitrogen (PAN) will then be calculated from this residual solids analysis. This information will
be used to calculate the loading rate for the field and crop.

Once the appropriate application rate has been calculated, the residual solids will be removed from the
respective treatment plant and transported to the site in leak proof tankers adapted for liquid residual
solids. Tankers will then travel major traffic routes to the fields whenever possible. Once at. the field,
the tankers will proceed to a designated staging area. The liquid residual solids will then be transferred
to a residual solids applicator designed and operated to obtain an even application consistent with
agricultural requirements.
All residual solids will be removed from the staging area by the end of the • working day, unless
equipment breakdown or weather prohibits the residual solids application. At the start of each day? all
fields will be inspected by the field superintendent. Equipment will only enter a field when conditions
are appropriate for the application. Residual solids will only be applied when the field is capable of
supporting equipment. When field conditions are not appropriate for an application, such as during
wet periods, the residual solids will remain at the WRF until field conditions are suitable for land
application.
Prior to the residual solids operations, the field superintendent and appropriate Havelock personnel
will inspect the site. During the field inspection, the field superintendent will note the standard North
Carolina Division of Water Quality (DWQ) buffer zones including: homes, drainage ditches, roads,
wells, surface water, and property boundaries (listed in Table 1). On the basis of these standard DWQ
buffers for land application programs, buffers will be established in the field. These buffers will be
identified in the field by the placement of pin flags.

C. Description of Plant Facilities
Wastewater from the City of Havelock's service area is collected and delivered to
the Havelock Wastewater Treatment Plant by the wastewater collection system.
The treatment plant provides tertiary treatment of the wastewater using the
activated sludge process followed by denitrification filters. The activated sludge
process at the Havelock WWTP operates in the single -stage nitrification mode.
After activated sludge treatment and filtration, the plant effluent is disinfected by
ultraviolet light before discharge to the East Prong of Slocum Creek. Solids
treatment is by lime stabilization followed by land application of stabilized solids to
agricultural land. Figure 1-1 shows a layout plan of the treatment facilities at the
Havelock WWTP. A process flow schematic for the Havelock Plant is shown on
Figure 1-2.
Wastewater from the collection system enters the treatment plant through a 15-
inch gravity interceptor sewer and an 8-inch force main. The influent wastewater
is combined in a manhole before entering a bar screen and grit collector. A
second bar screen is provided for standby use as a backup to the main bar screen
and grit collector. The bar screen removes rags, sticks, large organic particles and
other large objects to prevent clogging and interference with operation of
downstream pumps and other process equipment. The grit collector removes
heavy inorganics, such as sand, gravel, and other heavy materials that have
settling velocities significantly greater than those of organic solids. Grit is
removed to prevent excessive wear- on downstream pumps and other process
equipment and to prevent grit accumulations in process tankage. After grit
removal, the influent wastewater flows to two influent. pump stations.
The two influent pump stations lift the influent wastewater to an elevation from
which it can flow by gravity to the first -stage and second -stage aeration basins.
Return activated sludge (RAS) is combined with the influent wastewater prior to
HAVELOCKIO&M.1
1-2

pumping to the aeration basins. The aeration basin influent is pumped to a
distribution box, which distributes the flow equally to the two first -stage aeration
basins. The first -stage aeration basin effluent flows by gravity to the three
second -stage aeration basins. The first -stage aeration basins have fine bubble
diffused air aeration systems and the second -stage aeration basins have coarse
bubble diffused air aeration systems. The aeration systems provide the dissolved
oxygen and mixing necessary for the activated sludge process. Biological activity
in the aeration basins provides removal of BODS and provides complete
nitrification, which is the conversion of ammonia nitrogen to nitrate nitrogen.
The aeration basin effluent, or mixed liquor, flows to the Final Clarifier Pumping
Station for pumping to the Final Clarifier Distribution Box. The Final Clarifier
Pumping Station lifts the aeration basin effluent to an elevation at which it can
flow by gravity through the rest of the plant process units. The Final Clarifier
Distribution Box splits the flow equally between the two final clarifiers. The
activated sludge mixed liquor solids settle in the final clarifiers and are removed for
return to the aeration basins by the influent pumps or for wasting to the solids
treatment process. RAS and waste activated sludge (WAS) control stations are
provided for flow measurement and manual control of RAS and WAS flow rates.
The clear liquid above the settling solids overflows the final clarifier effluent weirs
and flows to the denitrification filters.
The three denitrification filters provide tertiary treatment, which is the removal of
the fine solids not removed by the final clarifiers. The filters have a layer of sand
media for filtration and also provide nitrogen removal by denitrification, which is
the conversion of nitrate nitrogen to nitrogen gas. The nitrogen gas is released
harmlessly to the atmosphere, and the effluent total nitrogen is reduced
accordingly. Methanol is added to the filters as a food source for the organisms in
the filter beds that accomplish denitrification. The filters are backwashed
periodically to remove excess or filtered solids, and the backwash water is
HAVELOCKIO&M.I
1-3

returned to the influent pump stations. Air scour facilities are provided for
backwashing and the air is provided by two blowers, one of which is also used for
aeration of the Stabilized Solids Holding Basin.
Denitrification filter effluent flows to the ultraviolet (UV) disinfection facilities,
which consist of one channel with two banks of UV lamps suspended in the
wastewater. The UV lamps provide disinfection' by the germicidal effect of the
ultraviolet light.
After disinfection, the plant effluent flows to the Reaeration Basin to allow
increasing the plant effluent dissolved oxygen to meet the dissolved oxygen
concentration limit in the plant's NPDES permit. Two surface aerators in the
Reaeration Basin introduce oxygen into the plant effluent. The Reaeration Basin
also provides a source of backwash water for the denitrification filters. Two filter
backwash supply pumps are provided in the Reaeration Basin. The plant effluent
then flows through a Parshall flume for flow measurement prior to discharge to the
East Prong of Slocum Creek.
Waste activated sludge from the final clarifiers flows to the Waste Solids Holding
Tank for short-term storage. WAS is then pumped by two submersible pumps in
the Waste Solids Holding Tank to two gravity belt thickeners. The gravity belt
thickeners increase the solids concentration of the WAS to reduce the volume
requirements for stabilization, storage, and ultimate disposal. Polymer is added to
the solids feed to the thickeners to improve solids capture and provide effective. -
solids thickening.
The thickened solids are pumped to the Solids Stabilization Tank, where the solids
are mixed with a lime slurry for stabilization by the high pH of the lime -solids
mixture. A silo is provided for storage of the lime used for solids stabilization.
The stabilized solids are pumped to the Stabilized Solids Holding Basin for storage
HAVELOCKtO&M.I

•
prior to land application. The Stabilized Solids Holding Basin provides either short-
term storage or Tong -term storage when solids cannot be applied to land for
extended time periods. A coarse bubble aeration system is provided for aeration
and mixing of the Stabilized Solids Holding Basin to prevent odors and to keep the
stabilized solids in suspension. Air for the coarse bubble aeration system is
provided by one of the air scour blowers for the denitrification filters.
The stabilized solids are disposed of by land application to permitted farm land.
Currently, approximately 310 acres are permitted for land application.
