4. Alternative Analysis Evaluation: N/A
PART IV- EVALUATION AND RECOMMENDATIONS
The Permittee,the Town of Dallas, is applying for renewal of the facility's NPDES permit
to discharge treated wastewater. During the investigation,it was noted that wastewater is
overflowing the influent channel walls during the wet weather. The City has installed sandbags
as temporary measures to prevent sanitary sewer overflow. Also,a temporary pump with flexible
piping has been provided to prevent overflows.
During the permit renewal of the Long Creek WWTP in the City of Gastonia, It was
learned that the Town of Dallas and the City of Gastonia hired an Engineering Company to look
into alternative analysis that would benefit both entities (engineering report is attached). This
Office obtained a copy of the Engineering report from the City of Gastonia. This report modeled
five (5) alternatives as follow:
A) Existing operations with entire CIP (Capital Improvement plan) and no expansion.
B) Purchase Gastonia Wastewater Treatment.
C) Purchase Gastonia water and Wastewater Treatment.
D) Merge with Gastonia/Maintain Dallas rates.
D1)Merge with Gastonia/Change to Gastonia Rates.
The Engineering report concluded the following: "Given the assumptions outlined
above, merging the two systems under the City of Gastonia will result in Dallas
customers seeing a noticeably lower monthly water and sewer bill in l0years, and
Dallas will maintain a healthier fund balance. Gastonia larger size enables it to spread
fixed costs over a greater user base and operate more cost effectively. If this option is
pursued, there is more financial benefit for Gastonia to maintain the Dallas rate
structure until the two meet,to assist Gastonia in funding the needed capital
improvements to the Dallas Utility system, and system interconnects."
It should be noted that Long Creek WWTP is permitted for 16 MGD and using only 6
MGD at this time, while the Town of Dallas is permitted for 0.6 MGD. Also, given
the existing deficiencies at the Dallas plant and the expenses for repair and future
expansion of the plant, it seems to be more beneficial to the Town to consider merging
its WWTP with the City of Gastonia.
Based on the above, it is recommended that the Town of Dallas is to pursue with
connections with the Long Creek WWTP if it is more beneficial to the Town and to the
City of Gastonia. Also, it will be more beneficial to the environment to eliminate one
wastewater treatment discharge to the water of the State.

Pending review and approval by the Western NPDES Program Unit, It is recommended
that the NPDES permit be renewed.

Subject: Issuance of NPDES Permit NC0068888
Town of Dallas WWTP
Gaston County
Dear Mayor Coleman:
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 October 15,2007 (or as
subsequently amended).
This final permit includes no changes from the draft permit sent to you on July 21, 2010. However, you
are reminded that a condition has been added to the permit requiring the submittal of an annual report
describing efforts made by the Town (if any) toward connection of its collection system to that of the
City of Gastonia and elimination of the existing discharge.
Dallas Branch is listed as an impaired stream on North Carolina's 303(d) list. This means that the
stream does not meet all water quality standards. This stream degradation may lead the Division to take
steps, including modification of the permit, to ensure protection of surface water quality.
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 150B 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.

Permit NC0068888
A. (2.) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia(labia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised February 1998, or subsequent
versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February
1998)or subsequent versions. `The tests will be performed during the months of February,'May,August and
November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple-concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed. If reporting
pass/fail results using the parameter code TGP3B,DWQ Form AT-1 (original)is sent to the below
address. If reporting Chronic Value results using the parameter code THP3B, DWQ Form AT-3
(original) is to be sent to the following address:
Attention: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the
report with the notation of"No Flow" in the comment area of the form. The.report shall be submitted
to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.

Permit NC0068888
•
A. (2.) CHRONIC TOXICITY,continued
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
If the Perrnittee monitors any pollutant more frequently then required by this permit, the results of such •
monitoring shall be included in the calculation & reporting of the data submitted on the DMR &all AT
Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.
A. (3.) ALTERNATIVE TO DISCHARGE - PROGRESS REPORTS
No later than January 15 during each year this permit is effective,the Town of Dallas shall submit a
report detailing actions taken and/or progress made toward connection of the Town of Dallas'
collection system to that of the City of Gastonia, with treatment of wastewater at the City of Gastonia's
Long Creek WWTP and discharge from its outfall. Connection to Gastonia would allow for the
elimination of the Town of Dallas WWTP discharge to Dallas Branch and rescission of NPDES permit
NC00688 88.

1.0 NARRATIVE:
The Town of Dallas is proposing to install a de-chlorination system at the Dallas waste water treatment
plant. This system will consist of a redundant pumping system to supply carry water for both the clorine
dosing system and the de-chlorination system. The existing carry water is supplyed through a city water
supply tap which will be removed when this new system is installed. Diamond Engineering,PLLC has been
contracted by the Town of Dallas to produce a set of plans for their proposed upgrade.
Currently,the plant uses water from the cities water system to mix with the chemical chlorine that is
distributed to the plant's aeration units. The Town would like to disconnect the city water service line and
install a pump and a I"PVC line that will connect upstream of the west aeration unit's discharge v-notch
weir. This line will provide dosing water from the west aeration unit to the chlorination building to mix
with both the chemical chlorine for the chlorination process and also with the sodium bisulfite for the
de-chlorination process.There will also be a pump and a 1"PVC line installed from the east aeration unit to
the chlorination building for use in the event that the west aeration unit is inoperable for some reason. New
'/d'PVC lines will carry the sodium bisulfite to each aeration unit and discharge at the downstream side of
the discharge v-notch weir in both units. The Waste water plan employees plan to perform this up grade
with plan employees.
This office has spoken with the regional office and was informed that an application was not necessary for
this only an Authorization to Construct.

2.0 CONSTRUCTION SEQUENCE:
1. Install all exterior lines(1"&3/4")from aeration basins to chlorinating room. Install supply
pumps to provide carry water at both aeration basins.
2. Install all interior lines. Install smart valves,and sodium bisulfite dosing pumps for both sides
of the system.
3. Disconnect existing City water supply and connect carry water supply system for both the
chlorination and de-chlorination system.
4. Calibrate the dosing system using the smart valves and begin doing operation.

3.0 CALCULATIONS:
Chemical Reaction
Chemical used for dechlorination: Sodium Bisulfite(NaHSO,)
Chemical reaction with Free Chlorine:
S032+HOC1•SO42+Cl-+H+
Chemical reaction with Combined Chlorine:
S032+NH2C1+H20•S042+Cl-+NH4+
Dosing Rate
Peak flow=20 mgd. Measured chlorine residual is approximately 0.51 mg/1
Maximum dosage of sodium bisulfite needed per day. Per EPA(832-F-00-002) 1.46 parts of(NaHSO3) to
dechlorinate 1.0 parts residual chlorine.
Daily Dosing Rate=(flow rate)X(chlorine residual)X(dosage rate)
=(0.45 mgd)X(0.51 mg/1)X(8.34 lb/Mgal.mg/L)X(1.46 mg/L SO3 per mg/L C12)
=2.79 lb SO3 per day
**regular testing of efflunent for residual Chlorine and adjustment of SO3 may be required.

Subject:NPDES Permit NC0068888
Dallas WWTP
Gaston County
Dear Mr. Hughes:
Our records indicate that NPDES Permit No.NC0068888 was issued on August 23,2005
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 Page 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. For new permits/facilities,the Division may supply an initial small stock of these
forms; however, if you fail to receive the forms,please contact this Office as quickly as possible.
The forms, including directions for their completion, and other important information are also
available at http://h2o.enr.state.nc.us/NPDES/documents.html. 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 fee may be required for your facility; if so, you will
receive 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
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.
To maintain compliance with discharge limitations,proper operation and maintenance of
a wastewater treatment facility and the development of a process control program are essential.
For those facilities having chlorine tablet disinfection,please be advised that chlorine tablets
approved for wastewater treatment use must be used; swimming pool tablets are not approved.
Also, be advised that DWQ staff need to have access to the facility's discharge point into the
receiving stream; please maintain a path along the outfall line to facilitate that access.
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 $25,000 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 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
Mooresville if you have any questions or need clarification. We look forward to providing any
assistance.
Sincerely,
D. Rex Gleason,P.E.

Permit NC0068888
A. (2.) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North
• Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised February 1998,or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or
subsequent versions. The tests will be performed during the months of February,May,August and November.
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all
treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit,then multiple-concentration testing shall be performed at a minimum,in each of the two following months as
described in"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"(Revised-February 1998)
or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
coaceniration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of"detectable impairment,"collection
methods,exposure regimes,and further statistical methods are specified in the"North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-I) for the months in which tests were performed,using the parameter code TGP3B for the
pass/fail results and TI1P 5B for the Chronic Value. Additionally,DWQ Form AT-3 (original)is to be sent to the
following address:
Atte tiol: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed A qu uic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the.reporting period for which the report is made.
Test data shall be complete,accurate,include all supporting chemical/physical measurements and all
concentration/response data,and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,the
permittee will complete the information located at the top of the aquatic toxicity(AT) test form indicating the

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

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 15 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.

Permit NC0068888 SECTION
Town of Dallas WWTP
Gaston County
Dear Mr. Vlaservich:
The NPDES Unit received your permit renewal application on March 27, 2001. Thank you for submitting
this package.
The permit renewal for this facility has been assigned to Charles Weaver. This staff member will 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 a year 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 NC0068888 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(919)733-5083,extension 511.
Sincerely,
Sb.,

Dear Mr. Williams:
Our records indicate that NPDES Permit No. NC0068888 was'
issued on September 27 , 1996 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. 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 (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.
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 conditions include special reporting requirements in the event
of noncompliance, bypasses, treatment unit/process failure$, 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 automatically transferable. If
you, as the Permittee, cease to need this Permit, then you should
request that the Permit be rescinded or transferred 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 Mooresville if
you have any questions or need clarification. We look forward to
providing any assistance.

system, with all necessary piping and appurtenances, at the above referenced facility.
This Authorization to Construct is issued contingent upon the installation of corrosion
resistant materials and in accordance with NPDES Permit No. NC0068888 issued January

The sludge generated from these treatment facilities must be disposed of in accordance
with G.S. 143-215.1 and in a manner approved by the North Carolina Division of Water

In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as
may be required by this Division, such as the construction of additional or replacement
wastewater treatment or disposal facilities.
The Mooresville Regional Office, telephone number (704) 663-1699, shall be
notified at least forty-eight (48) hours in advance of operation of the installed facilities so that
an in-place inspection can be made. Such notification to the regional supervisor shall be made
during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified water pollution control treatment system operator to be in responsible
charge (ORC) of the water pollution control treatment system. The operator must hold a
certificate of the type and grade at least equivalent to or greater than the classification assigned
to the water pollution control treatment system by the Certification Commission. The
Permittee must also employ a certified back-up operator of the appropriate type and grade to
comply with the conditions of Title 15A, Chapter 8G, .0202. The ORC of the facility must visit
each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding

position of ORC or back-up ORC.
A copy of the approved plans and specifications shall be maintained on file by the
Permittee for the life of the facility.
The Operational Agreement between the Permittee and the Environmental Management
Commission is incorporated herein by reference and is a condition of this Permit.
Noncompliance with the terms of the Operational Agreement shall subject the Permittee to all
sanctions provided by G. S. 143-215.6 for violation of or failure to act in accordance with the
terms and conditions of this Permit.
Failure to abide by the requirements contained in this Authorization to Construct may
subject the Permittee to an enforcement action by the Division of Water Quality in accordance
with North Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from
complying with any and all statutes, rules, regulations, or ordinances which may be imposed
by other government agencies (local, state, and federal) which have jurisdiction.
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted facility
has been installed in accordance with the NPDES Permit, this Authorization to Construct and
the approved plans and specifications. Mail the Certification to the NPDES Unit, Division of
Water Quality, 1617 Mail Service Center, Raleigh, NC 27699-1617.

A. (2.) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised February 1998,or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or
subsequent versions. The tests will be performed during the months of February,May,August and November.
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all
treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit,then multiple-concentration testing shall be performed at a minimum,in each of the two following months as
described in"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)
or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of"detectable impairment," collection
methods,exposure regimes,and further statistical methods are specified in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the for the
• dditionally,DWQ Form AT-3 (original) is to be sent to the
following address:

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or"the Division" Means the Division of Water Quality,Department of Environment and Natural
Resources.
3. EMC Used herein means the North Carolina Environmental Management Commission.
4. Act or"the Act" The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,
33 USC 1251,et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass 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. 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 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 limitation
is identified as "Monthly Average" under"Other Limits"in Part I of the permit.

Part II
Page 2of11
V
.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 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
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 all 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

Part I
Page 3 of 11
8.a. (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.
10. Calendar Day: A calendar day is defined as 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.
11. Hazardous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant: A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean
Water Act.
SECTION B. GENERAL CONDITIONS
1. Duty to Comply

SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Certified Operator
Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the facility by the
Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in
responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the
grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the
Certification Commission. The permittee must also employ a certified back-up operator of the appropriate type
and any grade to comply with the conditions of Title 15A NCAC Chapter 8G.0202. The ORC of the facility
must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding
weekends and holidays, and must properly manage and document daily operation and maintenance of the facility
and must comply with all other conditions of Title 15A, NCAC Chapter 8G.0202. Once the facility is classified,
the permittee shall submit a letter to the Certification Commission which designates the operator in responsible
charge within thirty days after the wastewater treatment facilities are 50%complete.
2. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control
(and related appurtenances) which are installed or used by the permittee to achieve compliance with the
conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and
appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities
or similar systems installed by a permittee only when the operation is necessary to achieve compliance with the
conditions of the permit.
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means 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.
(2) "Severe property damage" means substantial physical damage to property, damage to the treatment
facilities which causes them to become inoperable,or substantial and permanent loss of natural resources
which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not
mean economic loss caused by delays in production.

Part I
Page 7 of 11
4.b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but
only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provisions of Paragraphs c.and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II,
E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee
for bypass,unless:
(A) Bypass was unavoidable to prevent loss of life,personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance;and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph
d. (1) of this section.
5. Upsets
a. Definition: "Upset" means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the 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: A permittee who wishes to establish the
affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs,or
other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2)The permittee facility was at the time being properly operated;and
(3)The permittee submitted notice of the upset as required in Part II,E. 6. (b) (2) of this permit.

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
I. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or"the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC
1251,et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass 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. 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 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.

Part II
Page 2 of 14
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
limitation 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 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 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 all 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.

SECTION C. OPERATION ANT) MAINTENANCE OF POLLUTION CONTROLS
1. Certified Operator
Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the
facility by the Certification Commission, the permittee shall employ a certified wastewater
treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such
operator must hold a certification of the grade equivalent to or greater than the classification
assigned to the wastewater treatment facilities by the Certification Commission. The permittee
must also employ a certified back-up operator of the appropriate type and any grade to comply
with the conditions of Title 15A,Chapter 8A .0202. The ORC of the facility must visit each Class I
facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends
and holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A .0202. Once the
facility is classified, the permittee shall submit a letter to the Certification Commission which
designates the operator in responsible charge within thirty days after the wastewater treatment
facilities are 50% complete.
2. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This provision
requires the operation of back-up or auxiliary facilities or similar systems which are installed by a
permittee only when the operation is necessary to achieve compliance with the conditions of the

Part II
Page 8 of 14
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Bypassing of Treatment Facilities
a. Definitions
(I) "Bypass" means 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.
(2) "Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c.and d.of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II,E.6.of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass,unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C)The permittee submitted notices as required under Paragraph c.of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

Part II
Page 9 of 14
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
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.

Gaston County
Dear Mr. Williams:
In accordance with your request received August 9, 1993 and in accordance with our
Mooresville Regional Office recommendation, we are forwarding herewith the subject permit
modification. The only change in this permit is the reduction of the monitoring requirements
from a Class IV level to a Class III level. Enclosed please find the modified limits pages. These
pages should be inserted into your current permit and the old ones discarded. 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 December 6, 1983.
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, Post Office Drawer 27447, Raleigh, North
Carolina 27611-7447. Unless such demand is made, this decision shall be final and binding.
Please take notice that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirement to obtain other permits which may be
required by the Division of Environmental Management or permits required by the Division of
Land Resources, Coastal Area Management Act or any other Federal or Local governmental
permit that may be required. If you have any questions concerning this permit, please contact
Susan Robson at telephone number 919/733-5083.

5. Jviass/Dav Measurements
a. The "monthly average discharge" is defined as the total mass 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. 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 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 (IPily 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.

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

OTHER REQUIREMENTS
A. Requirements for Control of Pollutants Attributable to Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs
from industries using the municipal system may be present in the pernuttee's discharge.At
such time as sufficient information becomes available to establish limitations for such
pollutants, this permit may be revised to specify effluent limitations for
any or all of such other pollutants in accordance with best practicable technology or water
quality standards.
2. Under no circumstances shall the permittee allow introduction of the following wastes in
the waste treatment system:
a. Pollutants which create a fire or explosion hazard in the POTW, including, but not
limited to, wastestreams with a closed cup flashpoint of less than 140 Degrees
Fahrenheit or 60 degrees centigrade using the test methods specified in ATSM
standards D-93-79, D-93-80, or D-3278 (incorporated by reference, see 40 CFR
260.11). This prohibition does not apply to any aqueous solution containing less than
24 percent alcohol by volume which would otherwise be a hazardous waste under 40
CFR 261.21 by virtue of having a closed cup flashpoint of less than 140 degrees
Fahrenheit or 60 degrees centigrade;
b. Wastes which will cause corrosive structural damage to treatment works, and in no
discharges with pH less than 5.0 standard units unless the system is specifically
designed to accommodate such discharges;
c. Solid or viscous substances in amounts which cause obstructions to the flow in sewers
or interference with the proper operation of the treatment works;
d. Wastewaters at a flow rate and/or pollutant concentration which will cause an
inhibition or disruption of the POTW, its treatment processes, operation, or sludge
use and disposal;
e. Heat in amounts which will inhibit biological activity in the treatment works, resulting
in interference but in no case heat in such quantities that the temperature at the treatment
works influent exceeds 40°C (104°F) unless the works are designed to
accommodate such heat:
f. Petroleum oil, nonbiodeg,adable cutting oil, or products of mineral oil origin in
amounts that will cause interference or pass through;
g. Pollutants which result in the presence of toxic gases, vapors, or fumes within the
POTW in quantity that may cause acute worker health and safety problems;
h. Any trucked or hauled pollutants, except at discharge points designated by the POTW.
3. With regard to the effluent requirements listed in Part I of this permit, it may be necessary
for the permittee to supplement the requirements of the Federal Pretreatment Standards (40
CFR, Part 403) to ensure compliance by the permittee with all applicable effluent
limitations. Such actions by the permittee may be necessary regarding some or all of the
industries discharging to the municipal system.

Part III
4. The permittee shall require any industrial discharges into the permitted system to meet
Federal Pretreatment Standards promulgated in response to Section 307(b) of the Act.
Prior to accepting wastewater from any significant industrial user,the permittee shall either
develop and submit to the Division a Pretreatment Program for approval per 15 NCAC 2H
.0907(a) or modify an existing Pretreatment Program per 15 NCAC 2H .0907(b).
5. This permit shall be modified, or alternatively, revoked and reissued, to incorporate or
modify an approved POTW Pretreatment Program or to include a compliance schedule for
the development of a POTW Pretreatment Program as required under Section 402(b)(8)of
the Clean Water Act and implementing regulations or by the requirements of the approved
State pretreatment program,as appropriate.
B. Construction
No construction of wastewater treatment facilities or additions to add to the plant's treatment
capacity or to change the type of process utilized at the treatment plant shall be begun until Final
Plans and Specifications have been submitted to the Division of Environmental Management
and written approval and Authorization to Construct has been issued.
C. Groundwater Monitoring
The permittee shall, upon written notice from the Director of the Division of Environmental
Management,conduct groundwater monitoring as may be required to determine the compliance
of this NPDES permitted facility with the current groundwater standards.
D. Publicly Owned Treatment Works
All POTWs must provide adequate notice to the Director of the following:
1. Any new introduction of pollutants into the POTW from an indirect discharger 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 into that
POTW by a source introducing pollutants into the 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 of the
change on the quantity or quality of effluent to be discharged from the POTW.

E. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure -Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 90% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of February, May, August and November. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally,DEM Form AT-1 (original)is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 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 requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NO I'L: 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 retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
F. ENGINEERING ALTERNATIVES ANALYSIS CONDITION
The permittee shall continuously evaluate all wastewater disposal alternatives and pursue the most
environmentally sound alternative of the reasonably cost effective alternatives. If the facility is in
substantial non-compliance with the terms and conditions of the NPDES permit or governing rules,
regulations or laws, the permittee shall submit a report in such form and detail as required by the
Division evaluating these alternatives and a plan of action within sixty (60) days of notification by
the Division.

The permittee shall continuously evaluate all wastewater disposal alternatives and pursue the most
environmentally sound alternative of the reasonably cost effective alternatives. If the facility is in
substantial non-compliance with the terms and conditions of the NPDES permit or governing rules,
regulations or laws, the permittee shall submit a report in such form and detail as required by the
Division evaluating these alternatives and a plan of action within sixty(60) days of notification by
the Division.
E. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure(North Carolina Chronic
Bioassay Procedure-Revised*September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 90% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of February, May,August and November. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed,using the parameter
code TGP3B. Additionally,DEM Form AT-1 (original)is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 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 requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

SUBJECT: Dallas WWTP Classification
Class II to Class III
During a recent inspection of the subject facility it was
found that the classification was incorrect. Apparently your
Office did not receive a copy of the Rating Scale (copy attached)
which was prepared on December 5, 1991 by Mr. Mike Parker of this
Office.
Please note that a change has been made under the Sludge
Disposal section. Dried sludge which is not lime stabilized is
taken to the Gaston County landfill for disposal . The landfill
incorporates the sludge in the top two feet of cap soil . It is our
understanding that this information is needed by you for the new
rating scale.
If you have any questions, please contact Mr. Richard
Bridgeman, Mr. Crabb or me at (704) 663-1699 .

Subject: NPDES Permit No. NC0068888
Dallas WWTP
Gaston County, NC
Dear Mr. Vlaservich:
Our records indicate that NPDES Permit No. NC0068888 was
issued on November 16, 1992 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 4-7.
Pages 4-7 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
P.O. Box 950, 919 North Main Street, Mooresville, N.C. 28115-0950•Telephone [phone]•FAX [phone]

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 plus 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.
Sincerely,

1. Is this facility being constructed with Construction Grants Funds
(municipals only)? No
2. Special monitoring requests: none at this time
3. Additional effluent limits requests: n/a
4. Other: n/a
PART IV - EVALUATION AND RECOMMENDATIONS
The Town of Dallas is proposing to construct a 0.600 MGD wastewater treatment
plant to serve the Town and proposed anexation areas. Currently, the Town's
wastewater is being treated by the nearby City of Gastonia's Long Creek wastewater
treatment plant. Because of a recent increase in sewer use charges, the Town
has determined it to be more economical to build their own wastewater treatment
facility. The proposed facilities will be dual extended aeration type units with
flow being split between the two (2) plants.

A
The site is suitable for the construction of the proposed wastewater treatment
facilities. The receiving stream channel is well defined with no problems noted
with the proposed discharge location.
The WLA as promulgated by Technical Services has indicated stream flow to be
greater than 0 at 7Q10 and 30Q2 conditions. The recommended effluent limitations
for this discharge are as follows:
Parameter Limitation
Summer Winter
Flow 0.600 0.600
BOD5 (mg/1) 13.0 26.0
NH3 as N (mg/1) 8.0 16.0
TSS (mg/1) 30.0 30.0
Fecal Coliform (#/100 ml) 1000.0 1000.0
D. Oxygen (mg/1) 5.0 5.0
pH (s.u.) 6-9 6-9
It is recommended that an NPDES Permit be issued to the Town of Dallas.
