Subject: Draft NPDES Permit NC0069523
Union County Public Works—Tallwood Estates WWTP
Union County
Dear Mr.Neff:
•
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to
ensure a thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
> The daily average limit of dissolved oxygen in section A. (1)has been updated.
➢' Total mercury sampling has been added to A. (1)monitoring requirements.
➢ Section A. (3)has been added to explain the total mercury sampling frequency and measurement
' method. -
➢ Section A. (4)has been added to require electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports (DMRs).
> Regulatory citations have been added to the permit.
Please note that the Clear Creek is listed as an impaired waterbody on the North Carolina 303(d)Impaired ,
Waters List. Addressing impaired waters is a high priority 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.
With this notification, the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Union County area,per EPA requirements. Please provide
your comments, if any,to the NPDES Program no later than 30 days after receiving this draft
permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit.If you have questions concerning the draft,please contact
me at the telephone number listed at the bottom of this page, or via e-mail [[e-mail]].

Grade II Biological Water Pollution Control Systems j 15A NCAC 08G.0302]
A. (2) TEMPORARY MEANS OF DISINFECTION
[NCGS 143.215.1 (a)]
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 Mooresville 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 may not exceed 17 µg/L; therefore,
dechlorination methods may also be necessary to ensure protection of water quality
in the receiving stream. .
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 by a North Carolina certified laboratory (including field -
certified), even if these values fall below 50 µg/L.
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. .
A. (3) EFFLUENT MERCURY ANALYSIS
[G.S. 143-215.66]
The Permittee shall provide one effluent mercury'analysis, using EPA Method 1631E,
in conjunction with the next permit renewal application. The analysis should be
taken within 12 months prior to the application date. Any additional mercury effluent
mercury measurement conducted from the effective date of this permit and up to the
application date shall be submitted with the renewal application.
If the result of the mercury analysis is not provided with the application, the
application may be returned as incomplete and the Permittee considered non-
compliant.

Grade II Biological Water Pollution Control System [15A NCAC 08G.03021
A. (4) ELECTRONIC REPORTING OF M©NIT©RING REPORTS
[NCGS 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The final NPDES Electronic Reporting Rule was
adopted and became effective on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections
within Part II of this permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements 'Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for
each month and submitted electronically using eDMR. The eDMR system allows
permitted facilities to enter monitoring data and submit DMRs electronically using
the internet. Until such time that the state's eDMR application is compliant with
EPA's Cross-Media Electronic Reporting Regulation (CROMERR), permittees will be
required to submit all discharge monitoring data to the state electronically using
eDMR and will be required to complete the eDMR submission by printing, signing,
and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central. Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or
due to the facility being physically located in an area where less than 10 percent of
the households have broadband access, then a temporary waiver from the NPDES
electronic reporting requirements may be granted and discharge monitoring data may
be submitted on paper DMR fox ins (MR 1, 1.1, 2, 3) or alternative forms approved by
the Director. Duplicate signed copies shall be submitted to the mailing address
above. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the
month following the issuance of the permit or in the case of a new facility, on the last
day of the month following the commencement of discharge.

Permit NC0069523
Grade II Biological Water Pollution Control System [15A NCAC 08G.0302]
Starting on December 21, 2020, the permittee must electronically report the
following compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to
Request a Waiver from Electronic Reporting" section below).
r
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial
recipient at the time of each electronic submission. The permittee should use the
EPA's website resources to identify the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities
means the entity (EPA or the state authorized by EPA to implement the NPDES
program) that is the designated entity for receiving electronic NPDES data [see 40
CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic
reporting tool for each type of electronic submission and for each state. Instructions
on how to access and use the appropriate electronic reporting tool will be available as
well. Information on EPA's NPDES Electronic Reporting Rule is found at:
http://www2.epa.goy/compliance/final-national-pollutant-discharge-elimination-
system--npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting
Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To
obtain an electronic reporting waiver, a permittee must first submit an electronic
reporting waiver request to the Division. Requests for temporary electronic reporting
waivers must be submitted in writing to the Division for written approval at least
sixty (60) days prior to the date the facility would be required under this permit to
begin submitting monitoring data and reports. The duration of a temporary waiver
shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re-
applies for and is granted a new temporary electronic reporting,waiver by the
Division. Approved electronic reporting waivers are not transferrable. Only
permittees with an approved reporting waiver request may submit monitoring data
and reports on paper to the Division for the period that the approved reporting waiver
request is effective. •
Information on eDMR and the application for a temporary electronic reporting waiver
are found on the following web page:
http://deo.nc.gov/about/divisions/water-resources/edmr

4. Signatory Requirements (Supplements Section B. (11.1 (b) and Supersedes
Section B. (11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person
described in Part II, Section B. (11.)(a) or by a duly authorized representative of that
person as described in Part II, Section B. (11.)(b). A person, and not a position, must
be delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an
eDMR user account and login credentials to access the eDMR system. For more
information on North Carolina's eDMR system, registering for eDMR and obtaining an
eDMR user account, please visit the following web page:

system shall make the following certification [40 CFR 122.22]. NO OTHER
STATEMENTS OF CERTIFICATION WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared
under my direction or supervision in accordance with a system designed to assure that
qualified personnel properly gather and evaluate the information submitted. Based on
my inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief true, accurate, and complete. I am aware that there are
significant penalties for submitting false information, including the possibility of fines
and imprisonment for knowing violations."
5. Records Retention [Supplements Section D. (6.11
The permittee shall retain records of all Discharge Monitoring Reports, including

Permit NC0069523
A. (2.) 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 Mooresville 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 may not
exceed 17 ug/L; therefore, dechlorination methods may also be necessary to ensure protection of water
quality in the receiving stream.
The Division shall consider all effluent TRC values reported below 50 u,g/L to be in compliance with
the permit. However, the Permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 ug/L.
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.

the wastewater discharged during the sample period.
Act or"the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act(CWA),as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges"of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which is
not a designed or established or operating mode for the facility.
Calendar Day
The.period from midnight of one day until midnight of the next day. However, for purposes of this permit,any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.

Calendar Quarter
One of the following distinct periods: January through March,April through June,July through September,and
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
(3) 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 shaII 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

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent.The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time<24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.

monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the"daily discharge"is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement,the
"daily discharge"is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample,"above.)

PART IV - EVALUATION AND RECOMMENDATIONS
Union County Public Works Department is requesting renewal of its NPDES Permit for
the discharge of treated wastewater.
The old WWTP had began to deteriorate, so the plant was disassembled and a new plant
was constructed adjacent to the foot print of the old WW-rp. This new plant was put in service
on April 17, 2013: The WWTP is running at half of its capacity and only one aeration basin and
one clarifier are in service at this time,
the facilities appeared to be in good operational condition during the time of the
investigation.
Pending review and approval by the NPDES Unit, It is recommended that the NPDES
permit be renewed as requested.

PART IV - EVALUATION AND RECOMMENDATIONS
Union Counts Public Works Department is requesting an Authorization to Construct at
the Tallwood WWTP.
The existing facility consists of an above ground steel extended aeration type package
plant that is structurally impaired and no longer meets redundancy requirements for operation
according to applicant and therefore the old plant will be dismantled and a new plant will be
constructed in its vicinity.
The existing UV system of the old plant will be used for the new plant. A review of the
project description for the Tallwood Estates WWII' Replacement revealed that not all of the
WWIP components were listed on Section 2 of the A to C Permit Submittal. Also, according to
the consultant there will he two temporary pumps that will he used to pump from both sewer
lines discharging into the existing wastewater treatment to the new WWI P during the transition
period. During the meeting the consultant was informed for the need of a construction sequence
in order to ensure continuous operation of the treatment system. Also, a completed description of
the new wvap is to be submitted.
Pending review and concurrence by Construction Grants& Loans Section, it is
recommended that the authorizations to construct be issued provided that a construction sequence
is submitted and approved.

Dear Mr. Delk:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft .
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following changes from the terms found in your current permit:
• The facility description has been updated to better reflect the existing treatment units.
• A condition has been added to the permit describing actions you must take should the UV system not.
function properly. If the UV system fails and chlorine is used as an alternate means of disinfection,.
daily monitoring and a 17 µg/L. daily maximum limit for total residual chlorine will apply to the
discharge. This condition also contains an explanation regarding the reporting and compliance
determination of total residual chlorine values.
Pleasesubmit any comments to me no later than thirty days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in October 2008, with an effective

Taliwood Package Treatment Plant UV Disinfection
ATC No. 069523A01
Review Comments
1. If the existing chlorinator is intended to remain in place as a backup means of disinfection, it will
be necessary to provide dechlorination. A tablet dechlorinator installed in the UV bypass line, after
chlorine contact should suffice.
2. Confirm the existing standby generator is adequately sized to provide power for both the new UV
disinfection system and the plant's aeration system.
3. The UV equipment specified for this project consists of 2 lamp modules arranged in a single bank
of 4 lamps. Confirm this design can provide adequate disinfection at the peak hourly flow rate of
125,000 GPD. The manufacturer's product literature indicates that the rated flow capacity of the
specified unit is 100,000 GPD.
4. Please identify the property boundaries of the county-owned land at the plant site. The plans show
that the new UV equipment will be installed close to an existing fence. If the fence is at the
property boundary, the 50 ft setback requirement for process equipment cannot be met without a
recorded easement from adjacent landowner(s).
5. We suggest including a recommended lamp-cleaning schedule on the plans for the operator to
follow.
6. Is the Taliwood package treatment plant equipped with tertiary filters ahead of the proposed UV
disinfection system? Please advise.
7. Please revise Note 1 on Sheet M1. Delete the reference to payment of fines by the Contractor.
The Owner, not the Contractor, is responsible for payment of any fines for permit violations.
8. Note 5 on Sheet M I is inconsistent with the construction details shown on Drawing AIM 1. Please
clarify.
9. Provide three (3) sets of final plans and specifications to this office, labeled "Final. Not Released
for Construction".

PART III-EVALUATION AND RECOMMENDATIONS
The Permittee,Union County Public Works Department (UCPWD),has applied for an
Authorization to Construct for the construction of an ultraviolet disinfection system at the
Tallwood package treatment plant. The proposed addition will enable the County to meet future
TRC limit.
According to submitted design,the disinfection system(Trojan UV Model 3100K PTP)
will be provided in order to meet dosage requirements at the peak hourly flow of.125 MGD.
According to manufacturer specifications, the Trojan UV Model 3100K PTP can only handle a
hydraulic capacity of 0.1 MGD. Therefore, it appears that the proposed UV system is not
sufficient to meet,the disinfection requirements at the peak hourly flow of.125 MGD.
The existing chlorine disinfection facilities will remain in place as backup. An auto-dialer
alarm system, spare lamps, and one UV module have been provide d as required by the DWQ
reliability requirements for UV disinfection for Class "C"waters.

•
Upon resolution of the above concern, and pending review and concurrence by
Construction Grants&Loans Section, it is recommended that the authorization to construct be
issued.

lEl t AND SAW/ER
Description of.Proposed Facilities
NPDES permit NC0069523 issued for the Tallwood PTP includes a TRC limit of 17 µ.g/L that will
take effect on June 1, 2005. The permit is attached as Appendix No. 1. UV disinfection facilities are
proposed to replace the existing chlorine contact tank (CCT) as the primary means of disinfection at
the plant. The existing CCT will remain in service as a backup means of disinfection, with appropriate
bypass piping and valves provided.
The Board of County Commissioners of Union County authorized the Public Works Department of
Union County to waive formal bidding for purchase of UV disinfection equipment and standardize on
equipment manufactured by Trojan Technologies, Inc. (Trojan) at its wastewater treatment plants.
This written agreement is attached as Appendix No. 2. Trojan manufactures a unit that utilizes low-
pressure, medium-intensity UV lamps that will sufficiently disinfect the effluent flow at the Tallwood
PTP. Trojan has proposed the Model 3100K-PTP to meet the specified conditions at average and peak
flows. Information on the system to be provided at the Tallwood PTP is attached as Appendix No. 3.
The UV disinfection design meets the following effluent characteristics at the TalIwood PTP:
Plant annual average daily flow(AADF) rating 0.050 MGD
Plant peak flow rating(2.5 x AADF) 0.125 MGD
Receiving stream(River basin) Clear Creek(Yadkin/Pee Dee)
Receiving stream classification Class C
Total suspended solids monthly average 30.0-mg/L
Fecal coliform monthly geometric mean 200/100-mL
Total residual chlorine 17g/L
The existing CCT will remain online as temporary backup disinfection facilities in case the UV
disinfection equipment is out of service. During normal service, treated wastewater will flow through
the CCT (with no chlorine added) and then will flow through the UV disinfection facilities. Valves
are provided as part of this design to isolate the UV disinfection facilities for maintenance purposes
and discharge chlorinated effluent as a backup service.
Construction Sequence Plan
1. Contractor is responsible for maintaining the plant and outfall in service during construction of the
proposed facilities as required on Drawing M1, Note 1.
2. Contractor will locate existing outfall pipe.
3. Contractor will install doghouse manhole over existing pipe and maintain existing pipe in service.
4. Contractor will verify existing 8"effluent pipe elevation at treatment structure
5. Contractor will construct slab and install mechanical equipment.
6. Contractor will make piping connections to provide service through the new UV disinfection
equipment by connecting exposed existing piping to new tee and by cutting out existing piping
inside doghouse manhole.
7. Contractor will provide bypass pumping as needed while bringing new equipment and piping
online as required on Drawing M 1, Note 1.
8. Contractor will complete equipment testing and startup and will finish site work prior to turning
facilities over to the County.

October through December_
Composite Sample
•
A-sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 nil 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
(3) 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
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at •
a constant time interval. This method may only be used in situations where effluent flow rates vary
Iess than 15 percent The'grab samples shall be taken at intervals of no greater than 20 minutes apart
dating any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities* on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest "daily discharge"during the calendar month.

October 28, 2002 Copy
Memorandum
TO: Board of County Commissioners
County Manager
• Clerk to Board •
CC: Senior Staff Attorney
Director of General Services
FROM: Jon Dyer, Public Works Directo
SUBJECT: Standardization of Wastewater Treatment Plant Equipment
Ultraviolet Light (UV) Disinfection System(s)
Public Works is diligently pursuing capital improvement projects as they relate to the
Crooked Creek and Twelve Mile Creek wastewater treatment plants (WWTP's).
Improvements include final effluent disinfection systems. The means by which
• disinfection is accomplished must be reliable and capable of consistently meeting
- stringent State disinfection standards and should be friendly toward human health and
the environment. Ultraviolet Light (UV) meets these requirements and is the system of
choice for Public Works.The Twelve Mile Creek, Olde Sycamore and Grassy Branch
WWTP's currently use UV for final effluent disinfection. Ail three (3) UV systems are
manufactured by Trojan Technologies.
The Crooked Creek improvements call for UV to be added as a replacement for chlorine
and the Twelve Mile Creek improvements call for an additional UV unit to be added to
handle the increased design flow. Generally the purchase of an UV disinfection system
sized to meet the needs of either the Crooked Creek or Twelve Mile Creek WWTP's
would require formal bidding. However, pursuant to G.S. 143-129(e)(6)(iii), competitive
bidding is not required where standardization or compatibility is the overriding
consideration.
Public Works recommends that the standardization of UV equipment be adopted for all
WWTP projects and specifically for the Crooked Creek and Twelve Mile Creek
improvement projects. The following points support our recommendation:
• 1. A Known Standard of Performance-The Twelve Mile system was placed online in
December 1997. Since startup the system has performed satisfactorily through a variety
of flow conditions as have the Olde Sycamore and Grassy Branch systems.
Page 1 of 2
400 North Church St. . Monroe,North Carolina 281124804 Phone:[phone] . Fax:[phone]

./.
2. 'A known Standard of Technical Support- Since unit startup Trojan has consistently
provided an acceptable level of technical support and customer service. "Service after
the sale" is important, especially when dealing with specialized equipment.
3. Efficient Equipment Operation -staff is already competent with the operational
intricacies of the Trojan system. These intricacies include"trouble shooting", program
configuration and non-routine operation (as may be required for high flows, process
upset conditions, etc).
4. Efficient Equipment Maintenance-Staff is already competent at the required
maintenance of this sophisticated process equipment. Maintenance includes
maintaining critical fluid levels, sensor calibration and the replacement of key
components such as lamps, sleeves, ballasts, circuit boards and seals. The familiarity
with the equipment aids in the early detection of potential problems during routine
inspections.
5. Reduced Parts Inventory -Specialty Parts-The existing Twelve Mile Creek UV
' system, as well as the proposed Crooked Creek and expanded Twelve Mile Creek
systems would utilize like parts. Key components such as UV lamps, quarts lamp
sleeves, electronic ballasts and electronic circuit boards are not interchangeable
between manufacturers. By standardizing our equipment the quantity of spare parts
kept on-hand will be significantly reduced.
6. Reduced Parts Inventory -General Parts -general components such cooling pumps,
hydraulic pumps, fuses, breakers etc. will be common to all three (3) systems. Multiple
system manufactures would not provide such a high degree of commonality.
A firm written base price commitment has been obtained from Trojan for the proposed
- Crooked Creek and Twelve Mile systems. The base price for each system is
$285,000.00. Any required auxiliary equipment (such as electrical transformers,
communication cable etc.), taxes and startup are not included in the base price. The
Crooked Creek total system price, excluding tax, has been negotiated down from
$355,881.00 to $308,450.00. The exact Twelve Mile Creek total system price is not yet
known but is expected to be less than the Crooked Creek system since most of the
auxiliary equipment will already be included in the final expansion design.
In conclusion, Public Works has a Trojan UV 4000 system in service at the Twelve Mile
Creek WWTP. Capital improvement plans as related to the Crooked Creek and Twelve
Mile Creek WWTP's call for the purchase and installation of two (2) additional UV
systems. Due to the nature and complexity of UV disinfection systems, and with the best
interests of the County in mind, Public Works recommends standardization of the units.
Public Works desires to standardize with Trojan Technologies' systems and respectfully
requests that the Board allow Public Works to forego the formal bidding process for the
procurement of the UV systems. After Board approval the design, purchase and
installation of Trojan systems will be incorporated into the Crooked Creek and Twelve
Mile Creek WVVTP's improvements.
Public Works will be pleased to discuss these matters as may be required.

The Division issued NPDES permit NC OQ(i9523 to the Union County Public Works Department on
October 29,2003. Since you culled today to inform me that you have not received your copy,I checked the fileas, I
found that the permit still contained an error and did not require influent monitoring for BOI)and TSS.
f rtclosed please Find the corrected permit, I am sending it in its entirety since you never received the one
sent in October.This permit correction is issued pursuant to the requirements of North Carolina.General Statute 143-

dated May 9, 1994 (or as subsequently amended).
Please take notice that this permit is not transferable. This permit does not affect the legal requirement to
obtain other permits which may be required by the Division of Water Quality or permits required by the Division of
Land Resources, Coastal Area Management Act or any other Federal or Local government permit that may be
required.

Subject: Issuance of NPDES Permit NC0069523
Tallwood W\V TP
Union County
Dear Mr.Dyer.
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly,we are
forwarding the attached NPDES discharge 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 May 9,1994(or as subsequently amended).
This final permit includes the following corrections from the draft permit sent to you on September 10,2003:
• As this is a municipal facility,permit limits have been changed to monthly/weekly averages rather than monthly
averages/daily maximums,and the 85%removal requirement of TSS and BOD for municipalities has been
included.
• Instream monitoring has been waived as long as the facility is a participant in the Yadkin-Pee Dee River Coalition.
This permit includes a TRC limit that will take effect June 1,2005. If you wish to install dechlorination equipment,the
Division has promulgated a simplified approval process for such projects. Guidance for approval of dechlorination projects is
attached.
The North Carolina Wildlife Resources Commission has expressed concern about this discharge to Clear Creek because
of two species that are threatened and/or endangered that are found in these waters. The Division strongly recommends that
you consider ultraviolet(UV)disinfection for your facility. Chlorine can be acutely toxic to aquatic organisms and forms
secondary compounds that can also be detrimental to aquatic life. UV disinfection would reduce the chemical load in your
facility's effluent and reduce risks to aquatic life instream.
If any parts,measurement frequencies or sampling requirements contained in this permit are unacceptable to you,you
have the right to an adjudicatory hearing upon written request within thirty(30) days following receipt of this letter. This request
must be in the form of a written petition,conforming to Chapter 150E of the North Carolina General Statutes,and filed with the
Office of Administrative Hearings(6714 Mail Service Center,Raleigh,North Carolina 27699-6714). Unless such demand is
made,this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources,the
Coastal Area Management Act or any other Federal or Local governmental permit that may be required. If you have any
questions sooceerningthisjperrnit,please contact Dawn Jeffries at telephone number(919) 733-5083,extension 595.

Union County, NC
Dear Mr. Dyer:
Our records indicate that NPDES Permit No. NC0069523 was issued on•October 29, 2003
for the discharge of wastewater to the surface waters of the State from your facility. The purpose
of this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the Permit. If you have not already done so, it is
suggested that you thoroughly read the Permit. Of particular importance is Pages 4.
Page 4 sets forth the effluent limitations and monitoring requirements for your discharge.
Your discharge must not exceed any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types and sampling locations. Upon
commencement of your discharge (or operation), you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or approved by this Agency. If you
have not received these forms,they should be arriving shortly. If you fail to receive the forms, please
contact this Office as quickly as possible. I have enclosed a sample of the "Effluent" reporting form
(DWQ Form MR-1), plus instructions for completing the form. It is imperative that all applicable
parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be
required for your facility. You will soon be receiving a statement from our Raleigh Office. It is
imperative that the fee be paid in a timely manner so as to prevent enforcement action or possible
revocation of your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The

Dear Ault, Dyer:
Division personnel have reviewed and approved your application.for renewal of the subject permit. A1.ccordi.ngly,we ate
forwarding the attached NPDES discharge permit, This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215,1 and the Memorandum ofaAgreement between North Carolina and the U.S.Environmental Protection Agency
dated May 9, 1994 (or as subsequently amended).
This final permit includes the following corrections from the draft permit sent to you on September 1.0,2003:
• As this is a municipal facility,permit limits have been changed to monthly/wee'kly=averages rather than monthly
averages/daily maximums,and the 853/a removal requirement of TSS and BC)l) for municipalities has been
included.
• Instream monitoring has been waived as long as the facility is a participant in the Yadkin-Pee Dee River Coalition.
This permit includes a TRC luni:t that will take effect June 13 2005, if you wish to install dechlorination equipment,the
Division has promulgated a simplified approval process for such projects, Guidance for approval of dechlorination projects is
a.ttauhed,
"llse North Carolina Wildlife Resources Commission has expressed concern about this discharge to Clear Creek because
of two species that are threatened and/or endangered that are found in these waters, The.Division strongly recommends that
you consider ultraviolet (UV)disinfection for your facility. Chlorine can he acutely toxic to aquatic organisms and forms
secondary compounds that can also be detrimental to aquatic life. UV disinfection would reduce the chemical load iii your
facility's effluent and reduce risks to aquatic life instreatn.
If any parts,measurement frequencies or sampling requirements contained ui this permit are unacceptable to you,you
have the right to an adjudicatory hearing upon written request:within thirty(:30) days following receipt of this letter. This request
must be in the form of a written petition,conforming to Chapter 150.B of the North (axohna General Statutes,and filedwith the
Office of Administrative Hearings (6714 Mat1 Service Center, Raleigh,North Carolina 2. 699_.6714). Unless such de.mind is
made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. °['he Division may require
modification or revocation and reissuance of the permit. "Phis permit does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or permits required by the Division of lauid Resources,.the
Coastal Area Management act or any other federal or Local governmental permit that may be required. It you have any
questions concerning this permit, please contact Dawn Jeffries at telephone nurrtaier [phone],extension 595.

NPDES Permit Requirements
Page 1 of 16
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC 1251, et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case,of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values. •
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
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
(3) 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
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 1.5 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.
Version 6/20/2003

NPDES Permit Requirements
Page 2 of 16
In accordance with (4) above,influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s),that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or"the Division"
The Division of Water Quality,Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility, or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean,values of"0" (or"c [detection level]") shall be considered=1.
Grab Sample
Individual samples of at least 100 nil collected over a period of time not exceeding I5 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Instantaneous flow measurement
A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total
discharge.
Version 6/20/2003

•
NPDES Permit Requirements
Page 3 of 16
Monthly Average(concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform, the geometric mean of such discharges.
Permit Issuing Authority
The Director of the Division of Water Quality.
Quarterly Average (concentration limit)
The average of all samples taken over a calendar quarter.
Severe property damage
Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable,
or substantial and permanent Ioss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage excludes economic loss caused by delays in production.
Toxic Pollutant:
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
Upset
An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with
permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by
operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive
maintenance, or careless or improper operation.
Weekly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar week. In the case of fecal
coliform, the geometric mean of such discharges.
Section B. General Conditions

Dear Mr. Dyer.
The NPDES Unit received your permit renewal application on April 9, 2003. Thank you for submitting this
package.
The permit renewal for this facility has been assigned to a staff member. This staff member vil1 contact you
if further information is needed to complete the permit renewal. Please note that the NPDES Unit has
several vacant positions. This staff shortage has lasted for over 4 years and is delaying all permit renewals.
Our remaining permit writers are currently reviewing Authorizations to Construct, speculative limit requests,
major permit modifications and 201 plan updates ahead of permit renewals. This is necessary due to a
variety of factors, including mandatory deadlines in the statutes which govern our program.
If this staff shortage delays reissuance of NC0069523 the existing requirements in your permit will remain
in effect until the permit is renewed (or the Division takes other action). We appreciate your patience and
understanding while we operate with a severely depleted staff. If you have any additional questions
concerning renewal of the subject permit, please contact Charles Weaver at [phone], extension 511.

RESIDUALS MANAGEMENT PLAN
Tallwood WWTP
NPDES No. NC0069523
Union County, North Carolina
Residuals generated at the Tallwood WWTP will be transported via vacuum truck
to Union County's Crooked Creek WWTP (NC0069841). All residuals at the
Crooked Creek facility will be aerobically digested. The residuals will be
considered stable and therefore suitable for land application when the following
criteria are met:
1. At least seven (7) residuals samples will be collected and analyzed for Fecal
Coliform each monitoring period. The geometric mean of the densities of
these samples will be calculated and will be less than 2,000,000 Colony
Forming Units per gram of total dry solids prior to application.
2. Vector Attraction Reduction will be met through one of the following options:
a) volatile solids reduction of 38% or greater b) biosolids injection or
incorporation c) biosolids alkaline stabilization.
All residuals will be disposed of in accordance with Residual Land Application
Permit No. WQ0007486.

• you have not already done so, it is suggested that you thoroughly read the Permit. Of
_ - - particular importance are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must nor exceed any of the limitations set forth. The section
headed "Monitoring Requirements" describes the measurement frequencies, sample types
1. and sampling locations. Upon commencement of your discharge (or operation), you must

T furnished or approved by this Agency. If you have not received these forms, they should
•- i , — be arriving shortly. If you fail to receive the forms, please contact this Office as quickly as
.;.. , . ` .` possible. I have enclosed a sample of the "Effluent" reporting form (DEM Form MR-1),
plus instructions for completing the form. It is imperative that all applicable parts be

may be assessed for such violations. If you find at any time that you are unable to comply
with the terms and conditions of the Permit, you should contact this Office immediately. A
Special Order by Consent (SOC) may be necessary while pursuing action to obtain
compliance. _ -
As a final note, an NPDES Permit is normally issued for a five-year period. Permits
are not automatically renewed. Renewal requests must be submitted to this Agency no later
than 180 days prior to expiration. Please make note of the expiration date of your Permit.
This date is set forth on Page 1 of the Permit. -Also note that NPDES Permits are not
automatically transferable. If you, as the Permittee, cease to need this Permit, then you
should request that the Division of Water Quality rescind the Permit or request that DWQ
reissue the Permit to another party, if necessary.
As mentioned previously,the purpose of this letter is to advise you of the importance
of your NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in

each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
•
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
• and/or measured during the calendar week(Sunday-Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
• tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily •
Maximum,"in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is,therefore,an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as"Annual Average" in Part I of the permit.

6. Concentration Measurement
•
a. The "average monthly concentration,"other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
Iimitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow •
value) of all the-samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum"under"Other Limits"in Part 1 of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average"under"Other Limits" in Part I of the permit.
e. The"daily average concentration"(for dissolved oxygen) is the minimum allowable amount of -
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
• considered to be the"daily average concentration" for the discharge. It is identified as "daily
average"in the text of Part I.
f. The "quarterly average concentration" is"the average of ail samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
•
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June,July through September,and October through December.

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
•
b. An"instantaneous flow measurement"is a measure of flow taken at the time of sampling,when
both the sample and flow will be representative of the total discharge.
c. A"continuous flow measurement"is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
-a. Composite Sample: A composite sample shall consist of:
(1) 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
(2) 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 present gallon interval between sample collection fixed at
no greater than 1/24 of the expected total daily flow at the treatment system, or
(3)a single,continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no case may the time interval between effluent
grab samples be greater than six (6)hours nor the number of samples less than four(4)during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means •
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
• individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean,values of zero(0) shall be considered to be one
(1).
•
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows. -

reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities,lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset. •
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.

Subject: NPDES Permit No. NC0069523
Tallwood Estates
Union County, NC
Dear Mr. Lewis:
Our records indicate that NPDES Permit No. NC0069523 was
issued on September 12, 1994 for the discharge of wastewater to the
surface waters of the State from your facility. The purpose of
this letter is to advise you of the importance of the Permit and
the liabilities in the event of failure to comply with the terms
and conditions of the Permit. If you have not already done so, it
is suggested that you thoroughly read the Permit. Of particular
importance are Pages 4-5.
Pages 4-5 set forth the effluent limitations and monitoring
requirements for your discharge(s) . Your discharge(s) must not
exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies,
sample types and sampling locations. Upon commencement of your
discharge (or operation) , you must initiate the required
monitoring. The monitoring results must be entered on the
reporting forms furnished to you by this Agency. If you have not
received these forms, they should be arriving shortly. If you fail
to receive the forms, please contact this Office as quickly as
possible. I have enclosed a sample of the "Effluent" reporting
form (DEM Form MR-1) , plus instructions for completing the form.
It is imperative that all applicable parts be completed, and the
original and one copy be submitted as required.
The remaining Parts of the Permit set forth definitions,
general conditions and special conditions applicable to the
operation of wastewater treatment facilities and/or discharge(s) .
The conditions include special reporting requirements in the event
of noncompliance, bypasses, treatment unit/process failures, etc.
Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment
facilities. Any changes in operation of wastewater treatment

facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment
facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $10,000 per violation (and/or criminal penalties)
may be assessed for such violations. If you find at any time that
you are unable to comply with the terms and conditions of the
Permit, you should contact this Office immediately. A Consent
Order may be necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a
five-year period. Permits are not automatically renewed. Renewal
requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of
your Permit. This date is set forth on Page 1 of the Permit. Also
note that NPDES Permits are not transferable. If you, as the
Permittee, cease to need this Permit, then you should request that
the Permit be rescinded.
As mentioned previously, the purpose of this letter is to
advise you of the importance of your NPDES Permit. Please read the
Permit and contact this Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to
providing any assistance.

(approach taken,correspondence with region,EPA,etc.)
Tallwood Estates WWTP discharges to a 7Q10=0.0,30Q2>0.0 cfs stream. Recommend
removing Chronic Toxicity testing and adoption of all other limits. Instream data looks good.
No D.O. values below 5 mg/1 up or downstream and no instances of"no flow".
Facility has violated effluent flow limits 7 months in 2 years. Per staff report,A to C is for
0.016 MGD; however,facility is presently built at 0.050 MGD.A to C must be applied for 0.05
MGD(current permitted flow). Facility should be changed to a Class II Wastewater Facility and
monitoring frequency should be changed accordingly.

RE: Tallwood Estate WWTP
NPDES Permit No. NC 0069523
Union County
Dear Mr. Bridgeman:
In response to the letter received on December 22 , 1993 from
Ms. Brenda Smith, we offer the following explanation for your
consideration regarding the deficiencies in monitoring frequency
and the classification of the Tallwood Facility.
Initially the Tallwood waste water treatment plant was
permitted for 50, 000 gallons per day discharge into Duck Creek.
The renewed permit decreased the flow from 50, 000 to 16, 000 gallons
per day which on occasions created flow violation for the plant.
The violation reported in Mr. Duttons' report dated November
30, 1993 is due to sampling and reporting based on a grade two
plant instead of grade three.
In an effort to address the flow limitations for the facility,
Mr. Dusty Metreyeon; the ORC for the plant contacted Mr. Kim Colson
of your staff .
I was informed by Mr. Metreyeon that during their conversation
they discussed the rating of the facility and determined that the
plant had been mistakenly classified as a grade three plant. A
grade three plant requires a lot more sampling and reporting.
Because the plant is physically a class two facility, the ORC
interpreted the conversation with Mr. Colson that the ORC can
sample and monitor the 16, 000 gallon per day flow under a class two
facility rating. At that time class two facilities were required
to sample bi-monthly. Mr. Colson recommended to the ORC that the
County obtain the authorization to construct a 50, 000 gallon per
day plant. Mr. Colson also stated that once the County obtained
the authorization to construct a 50, 000 gallon per day plant, the
plant would be reclassified and re-permitted for the 50, 000 gallon

per day flow. Based on the above the ORC continued to monitor as
a class two facility at a 16, 000 gallon per day flow. In an effort
to follow Mr. Colson's recommendation, the Public Works Department
informed Mr. Leroy Rushing; the owner and developer of the Tallwood
Estates and the plant, that he needs to retain a qualified engineer
to certify to the State that the plant is a 50, 000 gallon per day
facility and request an authorization to construct a 50,000 gallon
per day instead of a 16, 000 gallon per day plant. While we were
waiting for the authorization to construct a higher flow plant
application to be submitted by Mr. Rushing and approved by the
State, we continued to turn in monthly monitoring data based on a
16, 000 gallon per day flow and a class two monitoring frequency.
We did not receive any correspondence from the State regarding
the sampling frequency and therefore assumed that we were reporting
properly until the issue is resolved by Mr. Rushings' submittal.
Once we realized that we need to sample based on class three
requirements, we immediately began to sample accordingly. We will
continue to monitor as a class three until the plant is re-
classified as a class two plant. We also have informed Mr. Rushing
that no additional development would be allowed until the issue is
resolved.
We apologize for any inconvenience this confusion has caused,
and we hope that the above explanation and Tallwood's WWTP
excellent water quality history will be taken into consideration.
We would also like to reassure the State that we will continue to
meticulously monitor the Tallwood facility and turn out the best
quality effluent as possible.
For additional information, please advise.
Sincerely,
fU

Subject:Modification to NPDES Permit NC00695.23
Tallwood Estates \X'WTP
Union County
Dear Mr. Dyer:
On January 1, 2001, a final permit for the subject facility became effective. On April 2, 2001, Wes
Bell of the Mooresville Regional Office (MRCS) officially notified the Division of Water Quality (Division)
that the total residual chlorine (TRC), temperature and pH monitoring requirements that were present in the
previous NPDES permit had accidentally been eliminated from the 2001 renewal. Accordingly, twice weekly
TRC monitoring, weekly pH monitoring, and daily temperature monitoring have been reinstated in the
permit. They will become effective on May 1, 2001.
Please find enclosed the revised permit pages. The revised pages should be inserted into your permit.
The old pages may then be discarded. All other terms and conditions contained in the original permit remain
unchanged and in full effect. This permit modification is issued under the requirements of North Carolina
General Statutes 143-215.1 and the Memorandum of Agreement between North Carolina arid the U. S.
Environmental Protection Agency.
If any parts, measurementfrequencies or sampling requirements contained in this permit
modification are unacceptable to you, you have the right to an adjudicatory upon written request
within thirty (30) days following receipt of this letter. This request , ,Vrate r :7,forming to
Chapter 1508 of the North. Carolina General Statutes, filed with the Office of Administrative Hearings (6714
Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be
final and binding.
If you have any questions concerning this permit modification,please contact Natalie Sierra at (919)

. Request for Adjusted Daily
Wastewater Flow Rate
Union County
Dear Mr. Wagner:
On March 29, 1999,-The Division of Water Quality received your wastewater flow - '-'- --•
reduction request and supporting documentation concerning existing wastewater flows associated
with the Tallwood Subdivision Wastewater Treatment Plant (NPDES NC0069523). Your letter
requested the Division to allow the reduction of the Division's standard wastewater flow
allocation rates associated with single family residences to 250 GPD per residence. In support of
your request, a year's worth of water usage averages, precipitation data, sewer flow from the Boy
Scout Camp and the average number of occupied residences were provided to determine an
average flow per residence. - .
• The.Division in accordance with 15A NCAC 2H .0219 (1) (3) completed an evaluation. -
This office used eight months Wastewater Treatment Facility's Effluent reports for the period of
June 1998 through January 1999. This period began after the sewer rehabilitation project was
completed in May 1998_ The peak flows were determined in accordance with 15A NCAC 2H
.0219 (1) (3). The average peak daily flow was calculated using the 10% of daily flows per each
month for this period, then subtracting the flow from the Boy Scout Camp. The residential flow
as calculated using the average peak daily flow was divided by the number of connected
residences as stated in your data. Using this technique as outline by 15A NCAC 2H _0219 (1) (3),
I calculated an average peak individual residential flow of over 300 GPD during dry months. This
flow is within the design criteria as stated in the rules. During expected wet months of
September, December and January, the flows calculated greatly exceeded design flows.
Therefore there is evidence that Infiltration and Inflow (I&I) problems remain in the collection
system. -
- - - The 250 GPD flow calculated by you was based on a monthly:average,.which is not in _ . . _ __
• accordance with 15A NCAC 2H .0219 (1) (3). A simple average, as computed in your letter, does
not aIIow for adequate treatment and disposal of wasterwater during peak periods. Using this
method along with I &I problems, the Division can not allow a flow reduction for the
Wastewater Treatment Plant. Once the reliability of the wastewater collection system has been • -.-•.

demonstrated through continued monitoring as required by the NPDES permit, and the I & I
problems have been corrected, you may again request a flow reduction for the subject Wastewater

a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or rnea5ured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days •
the tests w ere reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
•
b. The "weekly average discharge"is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday- Saturday) on which daily discharges
are sampled and measured, divided by. the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
is Part I of the permit.
c. The 'maximum daily discharge"is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum,"in Part I of the permit.
d. The."average annual discharge"is defined as the total mass of all daily discharges sampled
and/or rnesured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is. therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average"in Part I of the permit.

6. r tr 3zia Measi cement
a. The"average monthly concentration.'other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily .
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as'Monthly Average"under'Other Luntts
Part I of the permit •
• b. The"average weekly concentration,'other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the:case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coli form bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average"under'Other Limits"in
Pan I of the permit. •
c. The "maximum daily concentration"is the concentration of a pollutant discharge during a
calendar day. If Only one sample is taken during arty calendar day the concentration of
£allutant calculated from it is the "Maximum Daily Concentration'. It is identified ay_
Daily Maxirnumn" tinder"Other Limits"in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during,a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bactena is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average' under "Other Limits" in
Part I of the permit.
•
e. The "daily average concentration' (for dissolved oxygen)is the minimum allowable amount
of dissohed oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day,the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average"in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quaver: It is identified as "Quarterly Average Limitation in the text of Fart I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March.April through June,July through September,and October through December.

•
7. Ot.+te-_Me summent
a. Flow. (MGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement"is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow-measurement"is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device..
$. I.es of Samples
a. Composite Sample: A composite supple shall consist of:
r
(1) a series
har a a grab
nd combined les erllected at oportional to the rate intervals
of flow measu ed at the time of
eriod of
discharge
sample collection,or
(2) 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

PART III - EVALUATION AND RECOMMENDATIONS
The permittee , Union County Public Works Department , has
applied for an Authorization to Construct for the Tallwood
Estates WWTP . The original permittee obtained an Authorization
to Construct for a 0 . 16 MGD WWTP ; however , a 0 .050 MGD WWTP was
built . An Authorization to Construct was never obtained for the
0 .050 MGD WWTP .
It appears that the WWTP is capable of treating 0 . 050 MGD
according to the specifications . No specification was given for
the clarifier ; however , it is expected to be of adequate size .
The WWTP is a class II facility . The permit contains monitoring
for a class III facility . The permit should be changed to class
II monitoring.

Re: Tallwood Estates WWTP - NPDES Permit NC0069523
Dear Greg:
Please find attached the equipment proposal for the Tallwood
Estates WWTP. As we discussed on the phone the other day, we can
find no plans for the subject facility and we have not been able to
locate the manufacturer (they appear to be out of business) . The
attached information however, indicates all, of the significant
process units and the required sizing. I have visited the plant
and can certify that the process units and dimensions in place are
indeed consistent with the attached materials list.
As you are aware, the 16, 000 gpd design that the original ATC was
approved under was never built. The only plant built and the
existing plant is the plant described in the attached literature.
I will be forwarding a request for an authorization to construct
after the fact, with a $150. 00 check early next week.
Also attached is the sludge management plan of Union County for the
Tallwood WWTP.
If you have any questions, please do not hesitate to call.
Very Truly Your's

PART IV - EVALUATION AND RECOMMENDATIONS
Review of the Mooresville Regional Office's records indicated
that the approved facility should be a 0 .016 MGD extended aeration
package treatment plant per the Authorization To Construct dated
November 23, 1988 . The recent on-site investigation revealed that
the facility is a 0 .050 MGD treatment plant. •The Union County
Public Works Department needs to submit a request for an Authori-
zation to Construct a 0 .050 MGD wastewater treatment plant . It was
noted that the existing treatment facility was previously
classified as a Class III facility. It is recommended that the
facility be recclassified as a Class II facility and that the
Permit be renewed.

Subject: Renewal of NPDES Permit 3
Tallwood Estates WWTP
Union County
Dear Permittee:
The subject permit expires on October 31, 1999. North Carolina. General Stature 143.215.1(c) requires that an
application for permit renewal be filed at least 180 days prior to the expiration date,
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than May 4,
1999. Failure to request renewal by May 4, 1999 will result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending upon the delinquency of the request.
If any wastewater discharge will occur after October 31, 1999 (or if continuation of the permit is desired), the permit
must not be allowed to expire. Operation of waste treatment works or continuation of a discharge after October 31,
1999 would violate NCGS 143-215.1 and could result in assessment of civil penalties of up to $10,000 per day.
If all wastewater discharge has ceased at the subject facility and you wish to rescind this permit, contact Robert
Farmer of the Division's Compliance Enforcement Unit at [phone], extension 531, You may also contact the
Mooresville Regional Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items which you must
submit when applying for renewal of the subject permit.

Subject: Permit Modification-Chlorine Limit
NPDES Permit NC0069523
Union CountyfTallwood Estates
Union County
Dear Mr. Shalati
On•November 25, 1992, the Division of Environmental Management issued NPDES Permit No.
NC0069523 to,Union County. Based on a review of the Authorization to Construct submittal approved
on November 23, 1988 and subsequent updates approved on May 23, 1994, the Division is hereby
forwarding a modification to the subject permit. This permit modification changes the total residual
chlorine limit of 17 µg/1 to monitoring only for 0.050 MGD. Please insert the enclosed effluent pages and
discard the old pages. This permit modification becomes effective immediately.
All other terms and conditions in the original permit remain unchanged and in full effect. These
modifications are 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 December 6, 1983.
If this modification is unacceptable to you, you have the right to an adjudicatory hearing-upon
written request within thirty (30) days following receipt of this letter. This request must be in the form of .
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina 27604. Unless
such demand is made,this decision shall be final and binding.
Current DEM procedures require dechlorination and chlorine limits for all new or expanding
dischargers proposing the use of chlorine for effluent disinfection. The Division is reviewing chlorine
levels from all existing dischargers as part of the NPDES permit renewal process. In the future, effluent
limits and/or dechlorination may be required of existing facilities with chlorine problems. If the chlorine
levels in your facility's effluent are deemed too high, a chlorine limit or whole effluent toxicity requirement
may be added to your permit effluent limitations.
Since chlorination is being employed at your facility, residual chlorine levels should be examined
in light of this information. As a general rule, effluent concentrations should be less than detection (100
' µgfl). If this is not the case at your facility, please review the operation of your plant to determine the best
method to achieve these levels. Adding dechlorination during a plant modification will help reduce
environmental impacts and avoid delays in meeting any limits for residual chlorine which may be mandated
by DEM in the future. Please note that the addition of dechlorination is considered a modification of your
wastewater treatment process and it is your responsibility to request an Authorization to Construct from
this division as well as all supporting information.
