Subject: Final NPDES Permit Renewal
Permit NCO081621
Muddy Creek WWTP
Cabarrus County
Grade 11 Biological WPCS
SIC Code 4952
Dear Mr. Kiser
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
Please note that the receiving stream, Rocky River, is listed as impaired for turbidity, copper and
zinc on the North Carolina 2016 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.
The Division offers the following response to your comments received October 31, 2018; the
Permittee requested to terminate the limit requirements for the Whole Effluent Toxicity (WET)
once the facility has passed 8 consecutive tests. The objective of whole effluent toxicity limits
placed in NPDES permits is to prevent discharge of toxic substances in amounts likely to cause
chronic or acute toxicity to wildlife in the receiving stream and represents the only feasible method
of evaluating the combined effects of constituents of complex wastestreams. The limit
requirements were added in accordance with 15 A NCAC 02B.0200 and 15A NCAC 213.0500,
therefore, those requirements will not be terminated.

The final permit maintains the following significant changes identified in the letter sent on
October 2, 2018:
• Upstream and effluent total hardness quarterly monitoring have been added to the permit
for both flow tiers (0.15 and 0.3 MGD) as required by the implementation guidance for the
new dissolved metal standards [ See A. (L) and A. (2.)].
• Effluent pollutant scans requirements have been added to Effluent Limitations and
Monitoring Requirements [See A. (L) and A. (2)]. Special condition A. (4.) includes
specific three years in which the effluent Pollutant Scan shall be performed (2020, 2021,
2022) the results should be submitted with your next renewal application per Federal
Regulations [40 CFR 122.210)(4)]. In addition, at the end of the Special Condition, 2°d
species Toxicity Testing Requirements for municipal permit renewals per Federal
Regulations [40 CFR 122.210)(5)] have been added. Please review each paragraph
carefully.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR)
internet application has been added to your NPDES permit [See Special Condition A. (5)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (I.) and A. (2.)].
• Regulatory citations have been added to the permit.
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
Resources or any other Federal, State, or Local governmental permits that may be required.
If you have any questions concerning this permit, please contact Qais Banihani at [phone]
or via email at [e-mail]. _
Sincerely,
1c; Linda Culpepper, Director
Division of Water Resources, NCDEQ

A (3.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [ 15A NCAC 0213.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 0.60% at 0.15 MGD flow regime and
1.2% at 0.3 MGD flow regime.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase Il Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. The tests will be performed during the months of
January, April, July and October. These months signify the first month of each three-month toxicity
testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during
representative effluent discharge and 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 -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP313 for the Chronic Value. Additionally, DWR Form AT-
3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 monthlyear of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Water 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. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
Page 7 of 13

Permit NCO081621
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that
Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also
subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.216)(5).
The US EPA requires four (4) toxicity tests for a test organism other than the test species currently
required in this permit. The multiple species tests should be conducted either quarterly for a 12-month
period prior to submittal of the permit renewal application, or four tests performed at least annually in
the four and one half year period prior to the application. These tests shall be performed for acute or
chronic toxicity, whichever is specified in this permit. The multiple species toxicity test results shall be
filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal
application to the NPDES Permitting Unit.
A. (S.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.I(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program

Monitoring Reports
1. Reporting Reauirements (Supersedes Section D. (2.) and Section E. (5.) (a)1
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 I Division of Water Resources I 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 forms (MR 1, 1. 1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the

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.

October through December.
Com site 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 &wMle 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.

Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permince's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(I4)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittec's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [I5A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in I SA NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [ 15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "5IU"

noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which stakes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405471; or
4. Is designated as such by the Permittec on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
Y - the criteria in paragraphs I or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the P01V6''s effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

Subject: Issuance of NPDES Permit NCO081621
Muddy Creek WWTP
Cabarrus County
Class WW-3
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 the following major changes from the draft permit sent
to you on April 9, 2014.
➢ Per your request dated May 7, 2014, sampling for the following parameters has been
reduced to 2/Week: BOD5, Ammonia Nitrogen, Total Suspended Solids (TSS), and Fecal
Coliform.
➢ This monitoring reduction applies to the current design flow of 0.15 MGD. Upon
expansion to 0.3 MGD, sampling will revert to 3/Week for the first six months of
operation. If no compliance problems occur during the first six months, sampling will
then resume at 2/Week for the target parameters. See section A. (2) for details.
Please note that the Rocky River is listed as an impaired waterbody on the North Carolina
303 (d) Impaired Waters List. Water quality standards for Copper and Turbidity have been
exceeded instream. Addressing impaired waters is a high priority for the Division. Instream data
from the YPDRBA will continue to be evaluated. If there is noncompliance with this permit's
effluent limits and stream impairment can be attributed to your facility, then mitigative measures
may be required.
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

A. (3) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and specify that, if a state does not establish a system to receive such submittals,
then permittees must submit DMRs electronically to the Environmental Protection Agency
(EPA). The Division anticipates that these regulations will be adopted and is beginning
implementation.
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

1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)l
Beginning no later than 270 days from the effective date of this permit, the permittee
shall begin reporting 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 DENR / Division of Water Resources / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, NC 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 forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR.
Temporary waivers shall be valid for twelve (12) months and shall thereupon expire. At
such time, DMRs shall be submitted electronically to the Division unless the permittee
re -applies for and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:

Permit NC0081621
http: / /portal.ncdenr.org/web /wq / admin/bog/ipu / edmr
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.
2. Signatory Requirements [Supplements Section B (11) (b) and supersedes Section B
1�u
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:

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
Version 1110912011.1

NPDES Permit Standard Conditions

(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.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples 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.
Dail 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.)
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. 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).
DWR or "the Division"
The Division of Water Resources, Department of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facile Closure
Cessation of all activities that require coverage under this NPDES permit. 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 "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 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 CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
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 or other bacterial parameters or indicators, the geometric mean of such discharges.
Permit Issuing Authority
The Director of the Division of Water Resources.
Quarterly Average (concentration limit)
The arithmetic mean 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 loss 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 CWA.
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 or other bacterial parameters or indicators, the geometric mean of such discharges.

Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected
and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The
devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements is consistent
with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a
maximum deviation of less than 10% from the true discharge rates throughout the range of expected discharge
volumes. Flow measurement devices shall be accurately calibrated at a minimum of once per year and maintained
to ensure that the accuracy of the measurements is consistent with the accepted capability of that type of device.
The Director shall approve the flow measurement device and monitoring location prior to installation.
Once -through condenser cooling water flow monitored by pump logs, or pump hour meters as specified in Part I of
this permit and based on the manufacturer's pump curves shall not be subject to this requirement.
4. Test Procedures
Laboratories used for sample analysis must be certified by the Division. Permittees should contact the Division's
Laboratory Certification Section (919 733-3908 or http://portal.ncdenr.org/web/wq/lab/cert) for information
regarding laboratory certifications.
Facilities whose personnel are conducting testing of field -certified parameters only must hold the appropriate field
parameter laboratory certifications.
Test procedures for the analysis of pollutants shall conform to the EMC regulations (published pursuant to NCGS
143-215.63 et. seq.), the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section
304(g), 33 USC 1314, of the CWA (as amended), and 40 CFR 136; or in the case of sludge use or disposal,
approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been
specified in this permit [40 CFR 122.41].
To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection
and reporting levels that are below the permit discharge requirements and all data generated must be reported down
to the minimum detection or lower reporting level of the procedure. If no approved methods are determined
capable of achieving minimum detection and reporting levels below permit discharge requirements, then the most
sensitive (method with the lowest possible detection and reporting level) approved method must be used.
Penalties for Tampering
The CWA provides that any person who falsifies, tampers with, or knowingly renders inaccurate, any monitoring
device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not
more than $10,000 per violation, or by imprisonment for not more than two years per violation, or by both. If a
conviction of a person is for a violation committed after a first conviction of such person under this paragraph,
punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of not more than 4 years,
or both [40 CFR 122.41 ].

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part H of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [I 5A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011.1

NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee'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.
Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which

PART III - EVALUATION AND RECOMMENDATIONS
The Water and Sewer Authority of Cabarrus County (WSACC) has applied for permit renewal
for the discharge of treated wastewater at its Midland Plant. An authorization to construct was
issued in 2009, and the A to C approved an expansion from 0.075 MGD to 0.150 MGD
including the following:
1) A parallel system similar in design to the existing system
2) A new mechanical bar screen to handle the expansion
3) A new equalization basin
4) A new tertiary filter to replace the existing filter
The up -grade has been completed and the plant appears to be in good operational condition.
Also, a scada system was added to the facility during the expansion process. No problems were
noted during the site investigation.
Pending review and approval by the NPDES Unit, it is recommended that the subject
permit be renewed as requested.

facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.

PART III - EVALUATION AND RECOMMENDATIONS
The Water and Sewer Authority of Cabarrus County (WSACC) is applying for an authorization
to construct to expand the Muddy Creek WWTP from the existing 0.075 MGD to 0.150 MGD in
order to accommodate the future growth in the area. The proposed expansion will consists of the
following:
1) A parallel system similar in design to the existing system
2) A new mechanical bar screen to handle the expansion
3) A new equalization basin
4) A new tertiary filter to replace the existing filter
During the site investigation, it was learned from the Water and Sewer Authority of
Cabarrus County (WASAC) that a scada system (not proposed in the permit application) will
also be added during this A To C. Also, the equalization basin that will be constructed does not
match the description as proposed in the report.
Mr. Keith Lane, the consultant Engineer with McKim and Creed was contacted regarding
the above and was requested to submit an addendum to the application with the above changes.
Pending review and concurrence by Construction Grants & Loans Section, it is
recommended that the authorizations to construct be issued after the above requests have been
addressed and approved.

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.
B ass
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 Dav
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. 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
Version 1011012007

NPDES, Permit Standard Conditions
Page 2 of 16
➢ 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.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect
effluent grab samples at least every X hours [X = days detention time] over a 24-hour period. Effluent
samples shall be collected at least every six hours; there must be a minimum of four samples 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 122.2)
Daily Maximum
The highest "daily discharge" for conventional and other non -toxicant parameters. NOTE: Permittees may not
submit a "daily average" calculation [for determining compliance with permit limits] for toxicants. See the relevant
Federal effluent guideline[s] for the appropriate calculation interval.
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).
DWO 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 "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 nil collected over a period of time not exceeding 15 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.
Version 1011012007

NPDES Permit Standard Conditions
Page 3of16
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.
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 limitl
The average of all samples taken over a calendar quarter.
Severe property damagee
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 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.
U set
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 limitl
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
1. Duty to Comply
The Permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation
of the Clean Water Act and is grounds for enforcement action; for permit termination, revocation and reissuance,
or modification; or denial of a permit renewal application [40 CFR 122.41].
a. The Permittee shall comply with effluent standards or prohibitions established under section 307(a) of the

NPDES Unit Supervisor
SUBJECT: Total Residual Chlorine Policy for NPDES permits
Every three years the State is required by the Clean Water Act to review its surface water quality standards and
classifications, determine if changes are needed and to make any necessary changes. This review process is referred to
as the "triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface
water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before
the state's Environmental Management Commission on October 10, 2002.
The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic, Cyanide,
Methylene Blue Active Substances (MBAS) and Total Residual Chlorine (TRC). The Hearing Officer also
recommended the addition of a standard for Methyl Tert-Butyl Ether (MTBE).
All of the. Hearing Officer's proposed changes were adopted with the exception of NME. The changes took effect
on April 1, 2003. This memo documents the changes to the NPDES permitting policy for TRC limits.
Total Residual Chlorine (TRC)
Previously, TRC had an Action Level Standard, except in designated Trout waters. The Triennial Review changes
modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/1— The Aquatic Life Standard will
remain for designated Trout waters.
Aquatic Life Standard — 17 µg/L (freshwater only)
Trout Waters — 17 µg/L
Revised TRC Polity
➢ TRC limits will be assigned to permit renewals and all new permits issued after April 1, 2003.
➢ Facilities that do not use chlorine will not receive a TRC limit; however, the presence of a chlorine back-up
system to augment UV or other disinfection requires a TRC limit.
➢ Facilities discharging to streams with a 7Q10 <0.05 cfs (zero -flow streams) will receive a limit of 17 µg/L
➢ Limits will be capped at 28 µg/L to protect against acute impacts.
It is likely that many facilities will need to add dechlorination (or use another means of disinfection) to comply with
the new TRC standard. Therefore, a compliance schedule of 18 months from the effective date of the permit may
be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the
facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES
Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment.

Cabarrus County
The Division received your permit renewal application (and supplemental documentation
concerning the planned expansion at the site) on Mav 6, 1999. Thank you for submitting this
package in a timely fashion.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff.
That staff member will contact you if further information is needed to complete the permit
renewal. I regret to inform you that the NPDES Unit currently has five vacant positions. This
staff shortage is delaying our processing of permit renewals. Our remaining staff are currently
reviewing Authorizations to Construct, speculative limit requests and 201 plan reviews 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 your permit, the existing requirements in permit
NCO081621 will remain in effect until the permit is renewed (or other action is taken by the
Division). We appreciate your patience and understanding while we operate with a depleted staff.
If you have any additional questions concerning renewal of the subject permit, please contact me

Subject: Renewal of NPDES Permit NCO081621
Mud Creek WWTP
Cabarrus County
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.

Dear Mr. Shive:
Our records indicate that NPDES Permit No. NC0081621 was issued on December
15, 2000 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 and 5 .
Passes 4 and 5 set forth the effluent limitations and monitoring requirements for
your dischar-e. 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 failures, etc. Also addressed are requirements for a
certified wastewater treatment plant operator if you are operating wastewater

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 $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 Acy
gency 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.

Subject: Issuance of NPDES Permit NCO081621
Muddy Creek W%VTP
Cabarrus County
Dear Mr. Shive:
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 permit is scheduled to expire on October 31, 2003 in an administrative effort to better
align permitting and Basinwide Planning operations within the Division of Water Quality.
The revised expiration -date schedule for the Yadkin -Pee Dee River basin permits requires
that existing permits be modified.
In response to a letter from your office dated September 25, 2000, the permit holder's name
has been changed from "Cabarrus County Utilities Department" to "Water and Sewer
Authority of Cabarrus County". (Refer to permit cover page). Also, due to the fact the
subject facility does not use chlorine for disinfection, a footnote has been added to drop the
monitoring requirement for total residual chlorine unless it is added for disinfection. (Refer
to special condition A. (l.), A. (2.) and A. (3.)).
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.

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

PART H
STANDARD CONDITIOI`'S FOR NPDES PERMITS
SECTION A. DEFTNMONS
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, 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/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 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 1 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.

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.

Part H
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.
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) (B) of this permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such
as to prevent any pollutant from such materials from entering waters of the State or navigable
waters of the United States. The permittee shall comply with all existing federal regulations
governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued
by the Permit Issuing Authority for the utilization/disposal of sludge may be reopened and
modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The
permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of
Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit
is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation,
Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the
discharge of untreated or inadequately treated wastes during electrical power failures either by
means of alternate power sources, standby generators or retention of inadequately treated effluent.

it. The "monthly a\er2Fe discharge" is defined as the total mass of all daily discharges
samnpled a.*,4-'or measured during a calendar month on \khich daily discharges are sampled
an: measure., di- ided by the number of daily discharges sampled andlor measured during
such month. It is therefore, an arithmetic mean found by adding the %\ eights of the
pollutant found each da) of the month and then dividing this sum b) the number of days
the tests a ere reported. The limitation is identified as -Monthly Average" in Part 1 of the
permit.
b. The "W eelJl a%eraSe discharge" is defined as the total miss of 0 daily discharges sampled
at;d'or measured during the calendar Keel: (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
v.eights of pollutants found each day of the week and then dividing this sum by the
number of da; s the tests were reported. This limitation is identified as "Weekly Average"
in Pan I of thi permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If orJy 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
Nfaximum," in Part I of the permit»
d. The. "a-verage annual discharge" is defined as the total mass of all daily discharges sampled
and/or rre`ured during the calendar year on v.hich daily discharges are sampled and
r,,ersured, divided by the number of daily discharges sampled and/or measured during such
scar. 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
re -coed. Th;'s Iitrutation is defined as "Annual A'crage" in Pan I of the permit.

a. The "average monthly concentration- other than for fecal colifortn 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 simple or in the case of grab samples is the arithmetic mean (weighted by Dow
value) of all the simples 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 lirr nation is identified as "Monthly Average" under "Other Limits" at
Pan I of the permiL
b. The "average weekly content.-ztion," 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
ni;rnbcr 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 w eek. This lima itation idenor,ed as "Weekly Avenge" under "Other Limits" in
Part I of the petznit.
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
H'M ;1znt calculated from it is the "�iaximum Daily Concentration". It is identified as
"Dail\ TSa.-,imum" under "Other Limits" in Part I of the permit
d. The % erare 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 (w eighted 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
calen,lar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily a,erage concentration" (for dissolved oxygen) is the minimum a?lowable amount
of dissol%ed oxygen required to be available in the effluent prior to discharge averaged
o\er a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
Sam
ple is considered to be the "daily &verage concentration" for the discharge. It is
identified as "daily a-*crage" in the text of Part L
f. The "quarerly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Past I of the permit.

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 tool discharge.
e. A "continuous flow measurement" is a measure of discharge flOA' from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow

Dear Mr. Furr:
Our records indicate that NPDES Permit No. NCO0816214 was issued on November 13,
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 are Pages 4,5 and 6 .
Pages 4,5 and 6 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 (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
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 $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.

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.
B ass
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 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.
Version 612012003

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).
DWO 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 "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 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 11.6 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.

Permit NCO081621
Muddy Creek WWTP
Cabarrus County
Dear Mr. Machado:
The NPDES Unit received your permit renewal application on April 4, 2003. Thank you for submitting this
package.
The permit renewal for this facility has been assigned to a staff member. 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 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 NCO081621 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.

RE: Renewal of NPDES Permit NCO081621
MUDDY CREEK WWTP
CABARRUS COUNTY
Dear Ms. Stephens:
APR - 4 20M
We are requesting a renewal of the permit NCO081621 for the Muddy Creek WWTP.
The current permit is scheduled to expire October 31, 2003. There have been no changes
at the facility since issuance of the last permit.
The permit adequately describes the wastewater treatment plant. We would like to
continue with the tiered flows of .075 MGD, .150MGD, .300 MGD in the new permit.
Our sludge management plan consists of truck hauling excess bio-solids to the Rocky
River Regional Wastewater Treatment Plant, NPDES Permit No. NC0036269, for final
disposal. The Rocky River Regional Wastewater Treatment Plant is owned and operated
by the Water and Sewer Authority of Cabarrus County.
The permit renewal Package Checklist is enclosed. If you have any questions, please
contact me at [phone] EXT. 11 or fax [phone].

Dear Mr. Machado:

Subject: NPDES Permit Modification
Permit Number NCO081621
Muddy Creek Wastewater Treatment Plant
Cabarrus County
The Division of Water Quality acknowledges receipt of the following information:
• Permit modification request to drop the total residual chlorine monitoring requirement.
• Permit modification fee of $100.00 (Check Number 10122).
On September 23, 1994, the Division of Water Quality issued an Authorization to Construct a wastewater
treatment plant to the subject facility. The authorization granted construction of a raw sewage pump
station, force main, splitter box, bar screen, equalization basin, aeration basins, secondary clarifiers,
return sludge pumps, effluent filters, ultra -violet light disinfection, cascade aerator, effluent monitoring
box, sludge digester, and sludge holding tank.
Due to the fact the subject facility does not use chlorine for disinfection, the Division agrees to drop the
monitoring requirement for total residual chlorine. The attached effluent sheets have been modified to
reflect this change. Please replace the existing sheets with the enclosed effluent sheets. This modification,
becomes effective on September 1, 1996.
All other terms and conditions in the original permit remain unchanged and in full effect. This
modification 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 you have any questions concerning this permit, please contact Jeff Myhra at telephone number (919)
733-5083, extension 597.
S' cerely,

4. Air Quality and/or Groundwater concerns or hazardous waste
utilized at this facility that may impact water quality, air
quality or groundwater? No AQ or GW concerns nor will
hazardous waste be utilized at this facility.
PART IV - EVALUATION AND RECOMMENDATIONS
Cabarrus County (CC) proposes to construct a 0.300 MGD WWTP
(to be built in 0.150 MGD phases) to serve the Town of Midland and
surrounding area of southeastern Cabarrus County. This area is
projected to receive significant growth in the near future as a
result of a nearby highway expansion and the planned development of
a Midland business park. The facility will also provide much needed
sewer service to those residents who have failing septic tank
systems. At the present time, wastewater in the proposed service
area is domestic only. The WWT facilities will also eliminate the
proposed discharge from the Midland Business Park (NC0065498).
A preliminary modeling of the receiving stream by the
applicant's engineer considered stream characteristics based on
anticipated effects from the Rocky River WWTP located approx. 15
miles upstream of the proposed facility. Preliminary results
indicate that the recovery zone for D.O. is well above the proposed
discharge location, therefore, secondary limitations are
anticipated. This, however, cannot be assured until Technical
Support can complete a WLA for this facility. Additional WWT
facilities may be required pending receipt of the WLA.

Page Four
The applicant proposes to extend the outfall pipe from this
facility into the center of the Rocky River, thereby, aiding in
dispersion of the effluent.
Pending receipt and approval of the WLA, it is recommended
that an NPDES be issued to the County.

Permit Number NCO081621
Muddy Creek Wastewater Treatment Plant
Cabarrus County
Dear Mr. Machado:
The Division of Water Quality acknowledges receipt of the following information:
• Permit modification request to drop the total residual chlorine monitoring requirement.
• Permit modification fee of $100.00 (Check Number 10122).
On September 23, 1994, the Division of Water Quality issued an Authorization to Construct a wastewater
treatment plant to the subject facility. The authorization granted construction of a raw sewage pump
station, force main, splitter box, bar screen, equalization basin, aeration basins, secondary clarifiers,
return sludge pumps, effluent filters, ultra -violet light disinfection, cascade aerator, effluent monitoring
box, sludge digester, and sludge holding tank.
Due to the fact the subject facility does not use chlorine for disinfection, the Division agrees to drop the
monitoring requirement for total residual chlorine. The attached effluent sheets have been modified to
reflect this change. Please replace the existing sheets with the enclosed effluent sheets. This modification.
becomes effective on September 1, 1996.
All other terms and conditions in the original permit remain unchanged and in full effect. This
modification 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 you have any questions concerning this permit, please contact Jeff Myhra at telephone number (919)

Subject: NPDES Permit No. NCO081621
Muddy Creek WWTP
Cabarrus County, NC
Our records indicate that NPDES Permit No. NCO081621 was
issued on September 16, 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 4-9.
Pages 4-9 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,
advise you of the importance of
Permit and contact this office
you have any questions or need
providing any assistance.

Authorization to Construct
Muddy Creek
Wastewater Treatment Facility
Cabarrus County
Dear Mr. Waldroup:
A letter of request for an Authorization to Construct was received by the Division and final plans
and specifications for the subject project have been reviewed and found to be satisfactory. Authorization is
hereby granted for the construction of a wastewater treatment plant consisting of a raw sewage pump
station, force main, spli;ter box, bar screen, equalization basin, aeration basins, secondary clarifiers,
return sludge pumps, effluent filters, ultra -violet light disinfection, cascade aerator, effluent monitoring
box, sludge digester, and sludge holding tank with discharge of treated wastewater into the Rocky River.
This Authorization to Construct is issued in accordance with Part III, Paragraph A. of NPDES
Permit No. NCO081621 issued September 16, 1994, and shall be subject to revocation unless the
wastewater treatment facilities are constructed in accordance with the conditions and limitations specified in
Permit No. NC0081621.
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 Environmental Management.
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 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 Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC
27626-0535.

Upon classification of the facility by the Certification Commission, the Permittee shall employ a
certified wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater treatment
facilities. The operator must hold a certificate of the type and grade at least 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 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 must
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.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.
The sand media of the effluent filters must comply with the Division's sand specifications. The
engineer's certification will be evidence that this certification has been met.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Environmental Management 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.
One (1) set of approved plans and specifications is being forwarded to you. If you have any
questions or need additional information, please contact Jay Lucas, telephone number 919/733-5083.
