Subject: Issuance of NPDES Permit
Permit NC0026611
Morehead City WWTP
Carteret County
Class IV
Dear Mr. Whitlow:
Division personnel have reviewed and approved your application for the subject permit. Accordingly,
we are forwarding tlile attached NPDES 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 October 15, 2007 (or as subsequently amended).
Please note that the receiving stream, Calico Creek, is listed as an impaired waterbody on the 2012
North Carolina 303(4) Impaired Waters List. Impairments for copper, chlorophyll a, turbidity, low oxygen, and
fecal coliform are in ,icated. Future assessment of bacteria -based impairment for this SC class stream segment is
anticipated to change to enterococci to be consistent with the water quality standard. Addressing impaired
waters is a high pr'ority with the Division, and instream data will continue to be evaluated. If there is
noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then
mitigative measures may be required.
A mercury TMDL was approved by US EPA and implemented in this permit.
Summary of Requirements in Final Permit from Current Permit
1) Effluent Limitations and Monitoring Requirements page for 1.7 MGD was removed and Supplement to
Permit Cover Sheet narrative was corrected.
2) Total Chlorine Residual conditional limit and special condition was removed and a new UV narrative
and special condition was added.

8. The Permittee shall perform three Effluent Pollutant Scans during the term of this permit.
See special condition A. (5) EFFLUENT POLLUTANT SCAN.
See Condition A. (8) for instructions should the facility's permitted UV system fail and an alternate
means of disinfection is required. A Total Residual Chlorine monitoring requirement with a daily
limit is applicable if chlorine compounds are used for disinfection.

Permit NC0026611
(Continued A. (3) ACUTE TOXICITY PASS/FAIL LIMIT (QRTRLY))
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.
Test data shall be 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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requitrement will revert to quarterly in the months specified above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately until such time that a single test is passed. Upon
passing, 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 and reporting of the data submitted on the DMR
AT Forms.
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.
A. (4) CALCULATION OF TN AND TP LOADS
a. The. Permittee shall calculate monthly and annual TN Load and TP Load as
follows:
i. Monthly TN (or TP) Load (lbs/month) = TN (or TP) (mg/L) x TMF x
8.34
where:
TN = the average Total Nitrogen (or Total Phosphorus)
(or TP) 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

Permit NC0026611
(Continued A. (4) CALCULATION OF TN AND TP LOADS)
ii. Annual TN (or TP) Load (lbs/year) = Sum of the Monthly TN (or TP)
Loads for the calendar months January through December.
b. The Permittee shall report monthly TN Load (QM600) and TP Load (QM665)
results (lbs/month) on the last day of the appropriate discharge monitoring
report for each calendar month (January through December). Annual TN Load
(QY600) and TP Load (QY665) results (lbs/year) shall be reported on December
31st discharge monitoring report for that calendar year.

Permit NC0026611
A. (6) NOTIFICATION OF RELEASE
The Permittee shall notify the Division of Marine Fisheries/Shellfish Sanitation and Recreational
Water Quality Section of any release of partially treated wastewater or untreated wastewater into
Calico Creek. The notification shall be made within three hours of the spill to the North Carolina
Division of Marine Fisheries communication center at [phone]. This notification does not
relieve the permittee of other spill notifications procedures as required by other agencies.
A. (7) MERCURY MINIMIZATION PLAN (MMP)
The permittee shall develop and implement a mercury minimization plan during this permit term.
The MMP shall be developed within 180 days of the NPDES Permit Effective Date, and shall be
available for inspection on -site. A sample MMP was developed through a stakeholder review
process and has been placed on the Division website for guidance:
http://portalmcdenr.org/web/wq/swp/ps/npdes under "Model Mercury Minimization Plan"
The MMP should place emphasis on identification of mercury contributors and goals for reduction.
Results shall be summarized and submitted with the next permit renewal.
A. (8) TEMPORARY MEANS OF DISINFECTION
In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system should fail,
underperform, or otherwise be removed from effective service, the permittee or his agent should
immediately inform the Surface Water Protection Section staff of the Wilmington Regional Office of
this development and discuss temporary, alternate means for disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method of disinfection is
in use, and values must be reported on the discharge monitoring report. TRC in the effluent shall not
exceed the recognized minimum measureable TRC of 50 µg/L, all values shall be reported even
when less than 50 µg/L; therefore, dechlorination methods may also be necessary to ensure
protection of water quality in the receiving stream.
Use of a disinfection system other than the permitted UV system during circumstances not deemed
as emergency and/or temporary (replacement of lamps, lamp cleaning or maintenance, etc.) will be
considered a violation of the terms of this permit.

October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or

Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected
and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The
devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements is consistent
with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a
maximum deviation of less than 10% from the true discharge rates throughout the range of expected discharge
volumes. Flow measurement devices shall be accurately calibrated at a minimum of once per year and maintained
to ensure that the accuracy of the measurements is consistent with the accepted capability of that type of device.
The Director shall approve the flow measurement device and monitoring location prior to installation.
Once -through condenser cooling water flow monitored by pump logs, or pump hour meters as specified in Part I of
this permit and based on the manufacturer's pump curves shall not be subject to this requirement.
4. Test Procedures
Laboratories used for sample analysis must be certified by the Division. Permittees should contact the Division's
Laboratory Certification Section (919 733-3908 or http://portal.ncdenr.org/web/wq/lab/cert) for information
regarding laboratory certifications.
Facilities whose personnel are conducting testing of field -certified parameters only must hold the appropriate field
parameter laboratory certifications.
Test procedures for the analysis of pollutants shall conform to the EMC regulations (published pursuant to NCGS
143-215.63 et. seq.), the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section
304(g), 33 USC 1314, of the CWA (as amended), and 40 CFR 136; or in the case of sludge use or disposal,
approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been
specified in this permit [40 CFR 122.41].

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
(3)
(5)
(7)
(8)
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

BACKGROUND
The Town of Morehead City owns and operates a 2.5 MGD tertiary wastewater treatment facility
that serves the Morehead City community, population 8,900. The treatment facility discharges
treated 100% domestic wastewater to Calico Creek, a class SC-HQW water in the White Oak
River Basin. ;Calico Creek is also designated as a Primary Nursery Area (PNA) by NC Marine
Fisheries. Beginning in 2003 this facility was required and continued to use EPA Method 1631 to
measure merury.
Calico Creek,is listed on the 2012 North Carolina 303(d) list as impaired for copper, chlorophyll
a, turbidity, dissolved oxygen (DO), and fecal coliform (recreational). In 2007 the US EPA
approved rev sions to 15A NCAC 2B .0200 which included removal of fecal coliform as the
bacterial wat r quality standard for SB and SC class waters. The Permittee was advised in
August 200 1 that fecal coliform monitoring was no longer required. Future impairment
evaluation for SB and SC waters is expected to reflect the change in the bacterial water quality
standard.
As requested by Division of Marine Fisheries/Shellfish Sanitation, a special condition requiring
notification of any untreated wastewater releases to Calico Creek was added to this permit in
2005. The ivision also added Total Nitrogen (TN) and Total Phosphorus (TP) instream
monitoring i 2005 as a result of nutrient concerns in Calico Creek, and to evaluate the facility
impact.
HISTORY
2007 - Renewal issued with changes to both 1.7 MGD and 2.5 MGD pages for cyanide and
merclry monitoring with a petition condition. Suspected nutrient overenrichment from
the 9cpansion, resulted in the addition of annual mass -based limits for TN and TP for
2.5 MGD as directed by 15A NCAC 02B .0224 (1)(b). The appropriate nutrient limits
were determined by the Division and are based on an equivalent TN concentration of 5.5
Fact Sheet
NPDES NC0026611
Page 1 of 5

mg/L and TP concentration of 1 mg/L. A 12 month compliance date to provide time to
modify operations to meet the new TN and TP mass limits was granted.
- Clarification on bases of HQW limits was provided as requested by Permittee.
- Correction issued to change mercury sample type to grab.
2008 - Correction issued to change cyanide sample type to grab.
- Minor mod letter issued to discontinue fecal coliform monitoring, no longer required for
SC waters per US EPA 2007 approval.
- Signed Engineer Certificate received for partial completion for expansion to 2.5 MGD.
UV, stand-by power, and solids extended dewatering system not completed.
2010 - Signed Engineer Certificate received for completion of UV, stand-by power, and solids
extended dewatering system.
2012 — Requested and received copies of last five effluent pollutant scans lab summaries.
- Requested and received validations for di-n-butyl phthalate data and for treatment
components.
PROCESS
Domestic wastewater enters the facility via two collection stations, each one has its own
mechanical bar screen and transfer pumps. The pumped stations flows combine, pass through the
influent meter, enter the aerated grit chamber, and into reactor chamber 1. An influent composite
sampler collects samples.
Flow is distributed from chamber 1 to reactor chambers 2 and 3 which discharge into the two
oxidation ditches with surface rotors. Each chamber has its own mechanical mixers. The
combined flow from the ditches is treated with alum and ferric chloride via chemical addition
systems and is distributed to the two clarifiers. The recombined flow from the clarifiers
continues through the tertiary filters, post aeration basin, UV basin, effluent flow meter, and to
the outfall. An effluent composite sampler collects samples. The tertiary backwash water is
recycled to reactor chamber 1.
Removed sludge is collected in a sludge basin which is pumped to two aerobic digesters or can
be recycled to the plant. Solid mixture from the digesters are further dewatering via a belt press
and dryer, and mixed with lime to generate a class A soil conditioner. Water extracted during the
dewatering process is collected in a basin and pumped back to the grit chamber.
COMPLIANCE
During the previous five years there were two limit violations, one Total Suspended Solids (TSS)
and one pH. No fines were assessed. A new updated treatment facility with tertiary filtration,
UV, and nutrient reduction was successfully placed in service.

PERMITTING STRATEGY
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended reasonable potential analyses for effluent detected
toxicants to exceed their water quality standard (WQS), based on DMR data from April 2010 to
June 2012, d from the five submitted Priority Pollutant Analysis (PPA). Evaluations were
conducted fo total phenolic compounds, copper, nickel, zinc, and di-n-butyl phthalate.
Results suggst reasonable potential for the facility to discharge copper, nickel, zinc, and di-n-
butyl phthalate in excess of their WQS. Copper and zinc are action level parameters, based on
RPA guidance their monitoring will be amended to occur in conjunction with the quarterly
toxicity test. Nickel and di-n-butyl phthalate values were from a limited data set, per RPA
guidance will be monitored quarterly. Because of the HQW standards low level limits, and to
discern accurate data, a narrative will be added requiring a minimum detection level of 1 µg/L
for nickel and di-n-butyl phthalate. Toxicants will be re-evaluated at the next renewal.
In line with A guidance for no detects, cyanide monitoring will be removed from the permit
but will conti ue in the seasonal PPA.
UV Disinfect t
With UV as a disinfectant method, the total residual chlorine (TRC) conditional limit and TRC
special condition will be removed. A new disinfectant special condition and narrative will be
added, and will require notification of the Wilmington Office Surface Water Protection in the
event of failure or other malfunctions related to the UV operation, and when chlorination or
chlorination compounds are used. Compliance with a TRC limit defined as less than 50 µg/L will
be required wlien chlorination or chlorination compounds are used.
Nutrient Requirements
Monitoring and reporting of effluent TN will be expanded to include reporting of the
Nitrite/Nitrat Nitrogen (NO2-N + NO3-N) and Total Kjeldahl Nitrogen (TKN) components. To
define the flow parameter needed to calculate the TN Load and TP Load, a Total Monthly Flow
(TMF) parameter will be added. TN Load and TP Load parameters reporting will be expanded to
include monthly and annual reporting. A special condition defusing the calculation method and
reporting dates for TN Loads and TP Loads will be added.
Mercury TMDL Requirements
A mercury TJMIDL was approved by US EPA in October 2012 and has been implemented in the final
permit. Table II summarizes the available mercury data used to determine requirements:

municipal facility with a permitted flow greater than 2.0 MGD, a special condition requiring the
facility to develop a Mercury Minimization Plan was added to the final permit.
Whole Effluent Toxicity
The permit requires and is limited by quarterly acute toxicity testing using mysidopsis bahia, at
90% effluent concentration. The facility passed the 19 toxicity tests submitted since November
2007. Four second species, menidia beryllina, acute toxicity tests were submitted with the
renewal application and all were passing. The special condition narrative will be updated to the
current version.
Priority Pollutant Analysis (PPA) Scan
The results of five annual PPA were submitted with the permit renewal application. See RPA
Analysis for results. Per Division strategy will amend PPA requirement to 3 seasonal scans in
designated years and will update the special condition narrative accordingly.
Instream Monitoring
Temperature, dissolved oxygen (DO), chlorophyll a, TN, and TP are measured routinely at
designated points upstream and downstream from the discharge into Calico Creek. Both the
upstream and downstream DO seasonally vary from less than 4 mg/L in summer and above 10
mg/L in winter, this would be considered natural background. The low and high instream TN and
TP values follow the low and high effluent TN and TP values, the effluent TN and TP values
were consistently in compliance. Since the start up of the new tertiary treatment operation, the
instream chlorophyll a levels have been consistently lower.
Based on Calico Creek 2012 303(d) fecal coliform impairment, instream fecal coliform
monitoring was included in the draft permit. The Permittee requested removal of instream fecal
coliform monitoring as per the Division August 2008 letter it is no longer a WQS for SC waters.
The impairment was based on the previous WQS and prior to 2008 US EPA approval to remove
fecal coliform as the bacterial WQS for SC waters. The Division concurs with the Permittee
justification and will remove instream fecal coliform monitoring in the final permit.
Temperature, DO, chlorophyll a, TN, and TP instream monitoring will continue.
Shellfish Sanitation Notification
The Division of Marine Fisheries/Shellfish Sanitation notification special condition will
continue. The Division of Marine Fisheries/Shellfish Sanitation will be sent a copy of the draft
for review, and the final permit for its records.
Technical Corrections
Permit requirements and narratives associated with 1.7 MGD flow will be removed as the new
expanded 2.5 MGD facility is in operation. The component list will be updated to the treatment
components for the 2.5 MGD operation. The previously rescinded effluent fecal coliform
requirement will be removed.
SUMMARY OF PROPOSED CHANGES
In keeping with Division strategies the following will be incorporated into the final permit:
• Effluent limit page for 1.7 MGD will be removed, Supplement to Cover Sheet
narratives will be amended to reflect current operations and to define components for
2.5 MGD operation.
• Effluent TRC conditional limit and TRC special condition will be removed. A new
disinfectant special condition will be added.
• Effluent mercury and cyanide monitoring will be removed but will continue as part of
the PPA scan. A Mercury Minimization Plan special condition will be added
Fact Sheet
NPDES NC0026611
Page 4 of 5

• Effluent monitoring for copper and zinc will be reduced to quarterly in conjunction
with the toxicity test.
• Effluent quarterly monitoring for nickel and di-n-butyl phthalate will be added and will
include a footnote narrative defining minimum detection criteria.
• Effluent nutrient monitoring will be expanded to require reporting of (NO2-N + NO3-
N), tFKN, TMF, monthly TN Load, and monthly TP Load. A special condition defining
nutrl ent load calculation method and nutrient load reporting will be added.
• Ac to toxicity special condition narrative will be updated to current version.
• Effl ent fecal coliform requirement narrative (compliance rescinded by letter August
2008) and instream fecal coliform monitoring will be removed.
• Effluent PPA scan special condition will be revised to reduce requirements to 3
seasonal scans in designated years.

standard in 1 A
in question is currently listed as
was correctly made based upon the fecal

submitted using the fecal coliform method (now)
I am sure that with the change to the standard in late 2007 and the listing in 2008
- the need to change
the ambient monitoring was just overlooked, and could be corrected in this cycle.
As I understand the 303 (d) listing process, to enable a change in the listing of
the waters, a ditional
studies would need to be completed with a verification that the enterococci samples
are compliant
with the current standard, as written. That would require 5 samples to be taken
within a 30 day
timeframe. I do not have expertise in permit writing .. so, I will not be able to
say that a proposed
weekly sampling regime for (now) enterococci would always provide data to assess "a
geomean of 5
samples in 30 days" in ambient or the NPDES permit.

Also, I just realized that the new facility and its BNR technology to meet nutrient
limits requires it to be
classified as a Grade 4 facility which your cover letter shows but BIMS does not
(Steve needs to
address this) and it looks like not all your monitoring frequencies are based on
that level.

The following comment is provided based upon review of subject draft NPDES Permit:
1. Instream fecal coliform monitoring was not a requirement of the previous permit and is not
believed to be appropriate in the draft permit inasmuch as the State no longer uses fecal
coliform as a standard for Class SB and SC waters. Please remove the stream monitoring
requirements associated with fecal coliform.
Your consideration of the above comment will be appreciated. If you have any questions, please do
not hesitate to call me.

Dean,
I regret I inadvertently left the TSS code out but will be sure to include it in the
draft. I will also
revise the text in A. (3) to identify the DMR reporting days as suggested. The new
town manager
name will be used in the letter.
Below is a spcial condition and narrative I have used on other permits to address
potential use
of chlorination where uv was the treatment process employed. Let me know if this is
acceptable
or if I need to revise any portions.
This first narrative would go right after the A.(1) footnote section and the special
condition
would be added to the permit.
tX"See Condition A. (x) for instructions should the facility's permitted uv system
fail and an
alternate means of disinfection is required. A Total Residual Chlorine monitoring
requirement
with a daily limit is applicable if chlorine compounds are used for disinfection."
TEMPORARY MEANS OF DISINFECTION
Page 1

9-20-12 RE Copy of draft permit and fact sheet under peer review Morehead City WWTP NC0026611
In the event that the wastewater treatment plant's ultraviolet (uv) disinfection
system should fail,
underperform, or otherwise be removed from effective service, the permittee or his
agentshould
immediately inform the surface water Protection section staff of the wilmington
Regional office of
this development and discuss temporary, alternate means for disinfection of the
effluent.
If chlorine compounds are used as temporary means of disinfection, the total
residual chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method
of disinfection is
in use, and values must be reported on the discharge monitoring report. TRC in the
effluent shall not
exceed the recognized minimum measureable TRC of 50 ?g/L, all values shall be
reported even when
less than 50 pg/L; therefore, dechlorination methods may also be necessary to ensure
protection of
water quality in the receiving stream.
use of a disinfection system other than the permitted uv system during circumstances
not deemed as
emergency and/or temporary (replacement of lamps, lamp cleaning or maintenance,
etc.) will be
considered a violation of the terms of this permit.
Thanks,
Ron

Ron,

any facility using uv, I would keep the TRC stuff labeled as applicable or if
used in the event they
have to augment disinfection with it or switch to cl for some reason. See if you
Ol can squeeze in the TSS
parameter code in the table. under A(3)b. for reporting the mass, add that the
monthly is to be
reported on the last day of the month and yearly on December 31st otherwise co staff

Subject: NPDES Permit Renewal
Town of Morehead City
Wastewater Treatment Plant
NPDES Permit No. NC0026611
Enclosed is the Town of Morehead City's NPDES Permit renewal application for the 2.5 MGD
wastewater treatment plant, currently operating under Permit No. NC0026611. On August 31, 2010, our
engineer provided a final certification associated with expansion of the old facility from 1.7 MGD to 2.5
MGD. The new facility was designed to produce reuse quality water, and included a new headworks,
with influent flow meter and aerated grit removal; dual oxidation ditches with anoxic reactors, rotors,
mixers, and mixed liquor recycle pumps, two 70-foot diameter clarifiers; two traveling bridge tertiary
filters; dual post -aeration basins, with one floating aerator in each; a UV disinfection system, with three
banks of light; two 45-foot diameter digesters, with dual sludge return pumps and a sludge wasting
pump; a Class A sludge dewatering and drying system; and standby power.
The Town maintains aerobic digestion and land application of Class B sludge through Permit No.
WQ0006018, under the direction of SynaGro South. Additionally, the Town has a new sludge
dewatering and dryer facility capable of generating Class A sludge.
Shoud you have questions regarding this submittal, please contact Carl Dangerfield, Wastewater
Supervisor/ORC at [phone], or our engineer, Cecil G. Madden, Jr, P.E., with McDavid
Associates, Inc. at [phone].
Sincerely,
Tow rf Mo_ head City

TOWN OF MOREHEAD CITY
NPDES PERMIT TOPOGRAPHICAL MAP
SCALE: r = 2000'
Mattel, hdattd

Additional information, if provided, will appear on the following pages.
A. USGS Topographic Map sized 8.5" x 11" in response to Item B.2.
The map shows the area surrounding the WWTP.
1. The Map s ws the main structures of the WWTP.
2. There are n injection wells.
3. There are n known wells or springs within 0.25 miles of the WWTP. The adjacent stream, "Calico Creek" is also the
discharge 1 ation.
4. Digesters, Sludge Dewatering and Sludge Dryers are also located on the WWTP Site.
5. The WWT does not receive or process hazardous waste.
B. See Flow Schematic in partial response to Item B.3. A description of the WWTP process is as follows:
1. Mechanical Bar Screen - Removes trash.
2. Influent Pumps - Pumps influent to grit removal structure.
3. Aerated Grit - Removes grit via gravity separation and air lift.
4. Oxidation Ditches - Biological treatment units.
5. Chemical Feed - Adds alum or ferric chloride to effluent of oxidation ditches to remove phosphorous or improve
settling characteristics to enhance BOD5 and TSS removal.
6. Clarifiers - Removes suspended solids.
7. Traveling Bridge Tertiary Filters - More thoroughly removes solids.
8. Post Ae ation - Aerates effluent to maintain minimum dissolved oxygen level.
9. Ultravijlet Disinfection - Intense light in contact with pathogenic organisms causes the organisms to become
inactivated and renders them harmless.
10. Sludge Return and Waste Pumps - Transfers sludge underflow from the clarifiers or sludge from transfer pumps
either back to the oxidation ditches (return) or to the digester (waste).
11. Sludge Digester - Tanks to hold sludge while its organic matter biologically decomposes. Supernatant goes to
influent before bar screen.
12. Belt Press - Dewaters sludge and directs solids to the sludge dryer.
13. Sludge er - Uses heat and/or lime to further dewater and stabilize sludge solids.
14. Sludge torage - Provides a place to keep stabilized sludge until it can be utilized/disposed.
15. Secondary Sludge Pumping Station - Directs belt press filtrate back to the head reactor basins.
16. Flow Measuring and Recording - Measures and records influent and effluent flow rates and volumes. Send signals
for pacing chlorination/dechlorination rates and samplers.
17. Effluent Sampling - Automatically collects samples paced by measured flow or at specified time intervals.
C. See Site Plans G7B and G8B which provide a more detailed view of plant piping in response to Item B.3.
