Subject: Issuance of NPDES Permit NC0081621.
Muddy Creek WWTP
Cabarrus County
Class WW-3
Dear Mr. Fowler:
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

Division may require modification or revocation and reissuance of the permit. This permit does
not affect the legal requirements to obtain any other Federal, State, or Local governmental permit
that may be required.

Permit NCO081621
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
• Section E. (5.) Monitoring Reports
1. Reporting [Supersedes Section D. (2.1 and Section E. (5.) (a)]
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:
5 of 6

Permit NCO081621
http:Z/portal.ncdenr.org/web/wq/admin/boR/­"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. Si_gnatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B.
11 A d
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:
http://portal.ncdenr.org/webLwq/­`admin/bog/ipu/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system
shall make the following certification [40 CFR 122.22] . NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
U certify, under penalty of law, that this document and all attachments were prepared
under my direction or supervision in accordance with a system designed to assure that
qualified personnel properly gather and evaluate the information submitted. Based on my
inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief, true, accurate, and complete. I am aware that there are significant
penalties for submitting false information, including the possibility of fines and
imprisonment for knowing violations. "
3. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years
from the date of the report. This period may be extended by request of the Director at
any time [40 CFR 122.41 ] .

Subject: RE: draft permit review for NC0081621
Attachments: Reduction of Monitoring Muddy Creek WWTP.xlsx
Charles,
I used the data from the excel spreadsheet you provided to populate a spreadsheet program I used in the past, and
have attached it for your review. I only looked at the data from 1/1/11 to 12/31/13 since this was the same data range
reported by the permittee in the request. I also did not break out the data for separate seasonal limits but used a
weighted average based on the seasonal limits to come up with an annual limits and then evaluated all the reported
data. The end results was I concurred with the permittee assessment he met the criteria to reduce monitoring for BOD,
TSS, NH3-N, and Fecal Coliform. The difference was the winter BOD was not acceptable in the spreadsheet you provided.
I checked with Bob and using an average limit where seasonal limits occur is the suggested method so I recommended
monitoring reductions for all four parameters.
FYI: One other thing you will need to modify is the expansion tier page, you can also reduce BOD, TSS, NH3-N and Fecal
Coliform monitoring to 2/week but must add a conditional footnote stating for the first 6 months of operation under the
expanded tier monitoring reverts back to 3/week. Check with Bob on how this works and footnote language. I will put
the file back on your desk.
Hope this is helpful.

The following information is the response from the Water & Sewer Authority of Cabarrus County
(WSACC) with regard to the subject permit. WSACC requests your consideration of the following
changes to the draft permit. The majority of the comments will be referenced by page number from the
draft you sent me by email on 4/9/2014.
Page 2 of 6
Item 1) In addition to the treatment plant components, a new Flow Splitter Pipe was added to the
treatment plant that would allow better control of the flow through the aeration basins no matter how
many are in service. This new pipe does not alter treatment process therefore an Authorization to
Construct was not necessary. WSACC contacted the Mooresville Regional Office to confirm we were in
compliance with PART III OTHER REQUIREMENTS, Section A. Construction of the NPDES Permit Standard
Conditions.

ATTACHMENT 1
DWQ Guidance Regarding the Reduction of Monitoring Frequencies in
NPDES Permits for Exceptionally Performing Facilities
October 22, 2012
A. Purpose
In its efforts to reduce the regulatory burden upon permittees while maintaining adequate compliance
oversight over point source discharges, DWQ has developed the following guidance for the reduction
of monitoring frequencies in NPDES permits for specific target parameters. Standard minimum
NPDES monitoring frequencies are established in 15A NCAC 2B .0508 for discharges from facilities
with specific Standard Industrial Classification (SIC) categories. However, 2B .0508(b)(1) states: "If it
is demonstrated to the satisfaction of the Director that any of the tests and measurements, sampling
points, or frequency of sampling requirements, as required in this Rule for a particular SIC group, are
not applicable to the discharge of a particular water pollution control facility, or if it can be
demonstrated that the objectives of this Section can be achieved by other acceptable means then
such requirements may be waived or modified to the extent that the Director determines to be
appropriate." This document identifies criteria to be used by DWQ that satisfies the regulatory
standard for the allowance of reduced monitoring frequencies for facilities included in SIC 4952.
This guidance applies to facilities with outstanding NPDES program compliance histories, exhibiting
effluent discharges that are excellent in both quality and consistency. Such performance will
demonstrate that compliance for particular parameters can be adequately evaluated with less
monitoring. Facilities demonstrating consistent, long-term treatment performance at levels far below
effluent limitations (<50%) may be considered for a reduction in monitoring from existing permit
frequencies to a 2/week minimum frequency for the parameters BOD5, CBOD5 TSS, NH3-N and fecal
coliform/enterococci (the "target parameters").
B. Approval Criteria
Individual NPDES facilities shall submit a written request to modify their NPDES permit specifying
which parameters are to be considered for reduced monitoring . Permit holders must include with
their requests sufficient data, statistical analyses, and other information to support the justification for
reduced monitoring. NPDES permit staff shall review the application and supporting information.
Approval of reduced monitoring frequency shall be granted if all the criteria below are met:
• The facility has no more than one civil penalty assessment for permit limit violations for each
target parameter during the previous three years.
• Neither the permittee nor any of its employees have been convicted of criminal violations of the
Clean Water Act within the previous five years.
• The facility is not currently under an SOC for target parameter effluent limit noncompliance.
• The facility is not on EPA's Quarterly Noncompliance Report for target parameter limit violations.
• For BOD5i CBOD5, TSS, NH3-N and TSS, the three year arithmetic mean of effluent data must be
less than fifty percent of the monthly average permit limit. For fecal coliform or enterococci, the

three year geometric mean must be less than 50 percent of the monthly average permit limit. For
parameters with summer and winter limits, an annual arithmetic mean of the seasonal limits may
be used in the calculation.
• With the exception of fecal coliform or enterococci, no more than 15 daily sampling results over
the 3-year review period can be over 200% of the monthly average limit for BOD,5, CBOD!j, TSS,
or NH3-N . Values associated with documented impacts of extreme weather or events beyond the
control of the permittee will not be included.
• For fecal coliform or enterococci, no more than 20 daily sampling results may be over 200% of the
weekly average limit. Values associated with documented impacts of extreme weather or events
beyond the control of the permittee will not be included.
• For the four target parameters, sampling results shall not show more than two non -monthly
average limit violations during the previous year.
• Reduced effluent monitoring must not impair assessment of sensitive downstream uses, such as
endangered species.
C. Implementation
After IDWQ review and approval, the facility's NPIDES permit will be reissued with reduced monitoring
frequencies for qualified parameters. Additional NPIDES permit requirements will include:
• Eligible facilities may be granted a reduction from existing permit monitoring frequencies to a
2/week minimum frequency for the four target parameters. Reductions will be made for both
effluent and influent sampling.
• Where monitoring is reduced to twice per week, it must occur on any two non-consecutive days
during the calendar week (Sunday through Saturday).
• Required monitoring frequency reductions establish new permit minimums for monitoring. As
always, facilities may monitor more often than required in the permit.
• If a reportable event, as defined by the permit [e.g., Part 11 (E) (6 & 9)] occurs, any facility granted
reduced monitoring frequencies will be encouraged to monitor on a daily basis until the episode is
resolved.
Monitoring frequency reduction from the minimum frequencies reductions established by the rules are
based upon consistent, exceptional performance. DWQ may revoke on a case -by -case basis these
reductions if the facility begins to perform in noncompliance with permit limits. If a facility's monitoring
reduction for a specific parameter is removed through permit modification, reconsideration of
monitoring frequency reduction will only occur three years following the revocation/permit modification
action, or at the next permit renewal.

Hi Charles,
Hope things are pretty quiet there at the Archdale building with the legislature still in town. I see where you
were assigned the Muddy Creek WWTP for review so I wanted to let you know about an issue I discovered today
with the flow limit noted in BIMS. BIMS has the permitted flow as 0.075 MGD and therefore the facility was
flagged for a permit violation in March since they reported an average flow of 0.0874 MGD. However, when (-
went through our files I found an engineer's certification from 4/19/11 noting that the plant can now handle
0.150 MGD. I have attached that certification in case permitting does not have a copy. I know you will need to
reprogram BIMS once you write the permit so not sure if it worth your while to correct the flow in BIMS or not; I
am okay with manually addressing any violations until you can get the permit renewed.
Regards,
Marcia

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.

SUBJECT: RENEWAL — NPDES PERMIT NCO081621
MUDDY CREEK WASTEWATER TREATMENT PLANT
(MCWWTP), CABARRUS COUNTY
Dear Mr. Hennessy:
Enclosed is the subject permit renewal application, as well as aerial and topographic
maps showing the point of discharge. We have also enclosed a narrative description of
the sludge management plan for the facility, the flow diagram of the plant and the
schedule for improvements and implementation. Please find enclosed three (3) copies of
the application for the subject permit.
Since the last permit cycle, MCWWTP has undergone a system upgrade which doubled
the capacity of the treatment system. These upgrades included:
1) Installation of a 100,000 gallon equalization basin
2) Two (2) aeration basins
3) One (1) solids holding tank
4) One (1) extended aeration basin
5) Two (2) clarifiers
6) The sand filters were replaced with 2 Aqua Minidisk disk filters.
Plans are in place to install a new splitter box at the head of the treatment system. This
new splitter box will allow better control of the influent flow to the aeration basins and
will eliminate pumping water into and back out of the surge tank. This will not change or
affect the treatment process, effluent quality or design capacity of the treatment works.
Installation is tentatively set to begin during the spring 2013.
The permit adequately describes the wastewater treatment plant. We would like to
continue with the tiered flows of .150 MGD and .300 MGD in the new permit with the
additional footnote in each:
"Monitoring upstream (U) and downstream (D) are provisionally waved, based
on membership in the Yadkin -Pee Dee River Basin Association. If at any time
during the term of this permit membership is terminated, the Permittee shall
immediately notify the Division and conduct instream monitoring as stipulated
in this permit."

ATTACHMENT 4 of 4 Schedules of Imarovements & Schedules of
Implementation
(Provide information on any uncompleted implementation schedule or uncompleted plans for improvements that will affect
the wastewater treatment, effluent quality, or design capacity of the treatment works. If the treatment works has several
different implementation schedules or is planning several improvements, submit separate responses to question B.5 for each.)
Plans are in place to install a new splitter box at the head of the treatment
system. This new splitter box will allow better control of the influent flow to the
aeration basins and will eliminate pumping water into and back out of the surge
tank. This will not change or affect the treatment process, effluent quality or
design capacity of the treatment works. Installation is tentatively set to begin
during the spring 2013.
