A. (5.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodapbnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarler/ monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised-Februar),
1998) or subsequent versions. The tests mill be performed during the nronihs of jauuary.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 anti 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 1I 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
i\lonitoring Form (NIR-1) for the months in which tests were performed, using the parameter code TGP313
for the pass/fail results and THP313 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 Mad 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 7

Permit No. NC0021253
Should the permittce 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 requitement or tests performed by the North Carolina Division
of Water Quahty indicate potential impacts to the receiving stream, this permit may be re-opened and
modified to include alternate monitoring requirements or limits.
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: The City of Havelock submitted a permit renewal application on December
30, 2002. The permit expired on June 30,2003. The city requested a modification to the
permit to increase the permitted flow to 2.25 MGD based on the design capacity of their
treatment system. The Division has informed the city in several occasions that Slocum
Creek can't support any increase of the discharge due to poor water quality conditions in
the creek and lack of assimilative capacity and they were advised that any expansions
above 1.9 would require a relocation to the Neuse River. Since 1991 the city has been
evaluating a plant expansion and relocation to the Neuse River. Speculative limits were
provided in 1995 for an expanded discharge to the river.
The city is not a member of the Neuse River Compliance Association.
Facility Description: The City of Havelocks operates a 1.9 MGD tertiary treatment plant.
The plant consists of bar screen, grit collector, two first-stage aeration basin with coarse
bubble diffusers, two second-stage aeration basins with coarse bubble diffusers, two final
clarifiers, three denftrification filters with methanol addition, LJV disinfection, reaeration
basin, sludge holding tank, two gravity belt thickeners, and solids stabilization tank and
stabilized solids holding tank.
Basin Plan: The East Prong Slocum Creek is not rated in the basin plan. The area of
Slocum Creek adjacent to Cherry Point Marine Corps Air Station was affected in the past
by fuel spills. The site is currently a super-fund site.

LNBA instream data: Havelock is a member of the Lower Neuse Basin Association. The
Association has an ambient monitoring site downstream from the Havelock's discharge.
Data from this station show low dissolved oxygen values.
DMR Review: DMRs for the period of January 2002 to December 2003 were reviewed.
The average flow was 1.45 MGD in 2002 and 1.88 MGD in 2003. Flow has been
increasing and they are doing a study to evaluate I/I. The monthly average flow was
exceeded in March, May, June, July, August and December of 2003. NOVs were issued
for the flow exceedances and for Total Phosphorus in July 2002.
Total Copper was < 10 pg/L for all samples reported. Total Zinc averaged 48 mg/L with a
maximum value of 80 mg/L.
Effluent Toiricity: The facility performs chronic toxicity at 90%. In the past five years
they failed one test in 2001. With the permit application the facility submitted the results
for two alternate species tests.
Priority Pollutant Scan: Havelock submitted the results of one PPA with the permit
application. No parameters were detected.
SUMMARY OF PROPOSED CHANGES
• Weekly average limits for ammonia of 1.5 mg/1 for the summer and 3.0 mg/1 for
the winter were added to the permit. Federal requirements and Division Policy
require weekly limits for ammonia.
• Eliminate monitoring for Total Copper. All samples were below the detection level.
A condition to perform an Annual Pollutant Scan of the effluent was added to the
permit._ To meet federal regulations the Division is implementing the annual
pollutant scan for all municipal facilities with flows over 1 MGD.

Re: Renewal of NPDES Permit # NCO021253
City of Havelock Wastewater Treatment Plant
Craven County
i
Dear Mrs. Stephens:
The City of Havelock herein submits one original and two copies of permit
application form 2A for your review. The NPDES permit, which is currently in force,
allows the discharge of 1.9 MGD into the east prong of Slocum Creek. However, the
current capacity of the facility is 2.25 MGD. The City of Havelock requests
consideration of an increase in discharge flow up to the current capacity of the facility
(2.25 MGD) with the renewal of this permit. The City has continued to improve its
infrastructure since the last permit renewal, and the wastewater treatment facility is
currently meeting and exceeding the performance requirements of the NPDES permit.
Based on current-averages, the facility is performing well enough to add the additional
flow without exceeding the annual pounds requirement for total nitrogen.
If you need further information, please do not hesitate to contact Susan Rexrode,
Public Utilities Director at [phone] or Bill Ebron, Wastewater Treatment Plant
ORC at [phone].
Sincerely
Thomas A. P lips

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
hen the
s capable of
are appropriate for the application. Residual solids will only e applied w application, lurch as during
supporting equipment. When field conditions are not appropriate for an
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
HAVELOCKNO&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 BOD5 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
HAVELOCK\O&M.1 I-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
HAVEIOWO&MA 1-4

prior to land application. The Stabilized Solids Holding Basin provides either short-
term storage or long-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.

Thanks for the explanation. I know that the negotiations with EPA took a lot of effort on the Division's part. It looks
like a reasonable compromise.

Ms. Rexrode,
The number of second-species tests varies for each quarter of 2003. The number required has been
approved by EPA after prolonged negotiations to reduce the number of tests required. We're fortunate that
EPA budged from their original expectation: all renewal applications must include 3 PPAs and 4
second-species tests. Region 4 approved the following schedule of second-species tests:
Permits expiring Jan-Mar 2003 must conduct one second-species test.
Permits expiring Apr-Jun 2003 must conduct two second-species tests.
Permits expiring Jul-Sep 2003 must conduct three second-species tests.
Permits expiring October 2003 and later must conduct four second-species tests.
If your facility's permit expired in March 2003 (as the database indicated), you would only be required to
conduct one second-species test (as you discussed with Mike Templeton). However, you correctly noted
that your permit expires in June 2003. The later application deadline is the cause for the additional
second-species test.
If the draft permit for your facility is submitted to Atlanta without at least one PPA and two
second-species tox tests, Region 4 will object. Region 4 reviews all draft permits for major facilities and
will not allow us to issue a permit without the required number of tests.
I'm sorry I can't grant your request.

Thanks for your help. However, I am not sure that we can get two additional "second species"toxicity tests
completed before December. We do already have two more regular toxicity tests scheduled before November, and
we tentatively have the first "second species"test scheduled for late August/early September. We have based all
our schedules and costs for the City's budget based on information from Mr. Templeton at a recent LNBA meeting
that NCDENR would only be requiring one"second species"test and one Priority Pollutant scan. These are quite
expensive analyses, and we may need to request a budget amendment if there has been a change in the number
that North Carolina plans to require. Would one"second species" still be sufficient? We will also have quarterly test
data for chronic toxicity available from the past five-year permit period.
Thanks again,
Susan Rexrode

Ms. Rexrode, I will correct the expiration date for your permit in our database.
Since your permit was issued, the Division has switched to a new rdata-managemet system. Some errors
occurred during conversion of the thousands of permit records; your permit's expiration date was among
the errors.
Submit the permit application for your NPDES permit by January 1, 2003. Since your permit expires in
June 2003 and not March, conduct two of the additional toxicity tests described in the letter sent to you
last week.
Thank you for letting me know about the error. If you have any additional questions, simply reply to this
e-mail.

Dear Mr. Weaver:
The City of Havelock is in receipt of a notice of renewal for NPDES permit number NC0021253. The letter requests
our package by October 1, 2002 and lists the expiration date as March 30, 2003. Our NPDES permit of record
states that"this permit and the authorization to discharge shall expire at midnight on June 30, 2003". We are in the
process of working on the renewal now, but we expected to submit it by the end of December (or 180 days prior to
expiration) and some of our analyses are scheduled for later this year. Could you check the Division's records to
see if the expiration dates of the permit numbers may have been switched? We do have a land application permit
that expires on March 31, 2003 (WO0000702) that we plan to submit a package for in October, and we were
expecting a letter from NCDENR concerning that permit. If you have any questions, please do not hesitate to e-mail
me at [e-mail] or phone me at [phone]. Thank you for your assistance in this matter.

REISSUANCE OF NOTICE OF VIOLATION
Whole Effluent Toxicity(WET)Testing
Copper and Zinc Action Level Policy
NPDES Permit No.NC0021253
City of Havelock W WTP
Craven County
Dear Mr. Phillips:
This is to inform you that a review of your toxicity self-monitoring report form for the month of
January 2001 indicates a violation of the toxicity limitation specified in your NPDES Permit. You should
undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
You should have recently received a Notice of Violation dated March 27, 2001 for the January
2001 toxicity effluent limit failure. Unfortunately,the March 27 NOV contained incorrect notification
timeframes. The substantive chances include modification to the thirty day and nine month reporting
periods found on Page 2, Part a) and b)of the NOV. Due to this error, I hereby rescind the March 27,
2001 Notice of Violation issued for failing to achieve compliance with your WET limit for January and
reissue a new Notice of Violation dated April 2, 2001 for the January 2001 effluent toxicity limit failure.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by failure of two or more toxicity limit violations during the
toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES Permit.
Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs during
the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and is exceeding the action level for
these parameters. The policy states that whenever a facility experiences two or more toxicity limit
violations during a toxicity testing calendar quarter, the NPDES Permit will be modified to include
numeric limits for copper and/or zinc UNLESS the permittee provides one or more of the following:

2
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation (TIE)results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity
The Division has evaluated your copper and/or zinc monitoring data. The Division has also
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure.Based on this data your prospective
copper permit limit is 15 µg/L and prospective zinc permit limit is 125 µg/L.
.The permittee,'upon experiencing two or more toxicity limit violations during a toxicity
testing calendar quarter must either provide DWQ with: -
a) . Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation.
OR
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Please note that if you choose item b)above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s).. Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.

3
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to include copper and/or zinc numeric limitations,as appropriate.
Please note that your actions to notify DWQ of prospective limit acceptance or to notify DWQ of
plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals are
the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
