This is a follow-up to the phone conversation we had on 12-3-2018 notifying you of a
monthly average flow violation that occurred for the month of November 2018. The 0.150 MGD
permit limit was exceeded by an average flow of 0.211 MGD for the month.
The WWTP received 7.46" of rain between November 4 and November 26, 2018. In an
effort to prevent the sewerage from backing up in the collection system and causing an SSO I ran a
higher volume of flow through the plant. This allowed more water to move through the treatment
plant faster while maintaining the other permit limits. MCWWTP had two 24 hr periods of nearly
0.3 MGD and one 24 hr period of 0.318 MGD.
Currently MCWWTP is under construction for expansion that will increase treatment capacity to
0.300 MGD. The construction started in February 2018 and is expected to be complete June 19,
2019. Attached to this letter is a statement from WSACC's Collection supervisor Wayne Lyles
explaining the steps they have taken to identify the I&I problem areas and the steps they have taken
to correct the problems they have found.
If you have any questions, please contact me at [phone] or [phone].

Subject: Water and Sewer Authority of Cabarrus County
Muddy Creek WWTP — Drainage Pumping Station
Request for Authorization to Construct
Gentlemen:
1968.022 (34)
On December 19, 2016, the Water and Sewer Authority of Cabarrus County (WSACC) was issued
A to C No. 081621A02 granting expansion of their existing 0.15 MGD Muddy Creek WWTP to a
permitted capacity of 0.30 MGD. Construction began in December 2017 and is on -going. On
July 12, 2018, a representative of the Division of Water Resources Mooresville Regional Office
conducted an inspection of the existing Muddy WWTP to verify compliance with NPDES Permit
No. NC0081621. A Notice of Violation (Tracking Number: NOV-2018-PC-0259) was issued on
August 9, 2018 noting "that influent sampler is not located above all side streams of wastewater
such as filter backwash water and sludge dewatering supernatant".
Upon receipt of the NOV, WSACC and Willis Engineers contacted Mr. W. Corey Basinger, DWR
Regional Supervisor, and arranged an on -site meeting to review options for compliance of the
requirements. It was agreed that the plant sewer system would be intercepted just upstream
of the influent pump station diverting the side stream to a new drainage pumping station
discharging directly into the existing equalization basin; thereby, by-passing the influent
sampler.
Given that the previously approved expansion project is still under construction, WSACC wishes
to utilize the existing contractor and technical specifications for the current Contract to
construct the proposed Drainage Pumping Station. We are uncertain whether this work would
be deemed a modification to the previously issued A to C or a new A to C would be required.
Regardless, we have prepared an Application for Authorization to Construction with the
pertinent sections completed. Enclosed please find one set of the following documents, along
with a CD containing the documents, for your review:
• The original executed Application for Authorization to Construct (Form ATC-12-14)
• NPDES Permit No. NCO081621
• Contract Drawings for the Drainage Pumping Station.
• Revised Flow Diagram
• Engineering Calculations

We understand that the Mooresville Regional Office may need to confirm that the proposed
design meets their expectations so a copy of the enclosed submittal package is also being sent
directly to Mr. Basinger. We look forward to your favorable review. Should you have any
questions or need additional information, please advise.
Yours very truly,

Project Description
Drainage Pumping Station
In August 2018, WSACC was issued a Notice of Violation by NCDEQ due to the influent sampler not
being located above all side streams of wastewater, such as filter backwash water and sludge
dewatering supernatant. After subsequent discussions and an on -site meeting with representatives of
the NCDEQ Mooresville Regional Office, it was concluded that a Drainage Pumping Station intercepting
the plant sewer side stream and pumping it directly into the Existing Equalization Basin was a suitable
solution. This arrangement would remove the side stream from the influent pumping station and
subsequently the influent sampler.
Design Basis
The proposed facilities will intercept the plant sewer flow at MH 12 and divert the flow to a 6-foot
diameter wet well with a single submersible chopper pump. The pumping station will convey the flow
through a 4-inch force main to the adjacent equalization basin. The normal pumping volume for the wet
well will be approximately 420 gallons. The duty point for the pump is 208 gpm at 33-feet TDH,
sufficient to handle backwash from multiple filters, clarifier scum flow and other normal plant return
streams. In the event, the side stream flow too great the flow will overflow into the sewer discharging
into the influent pump station.

Auxiliary Power Source
The new electrical system and generator being constructed as part of the on -going expansion project is
sufficient to handle the new drainage pumping station.

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 II 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 H 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 month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
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.

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 122.210)(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

application to the NPDES Permitting Unit.
A. (5.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
Page 9 of 13

Permit NCO081621
NOTE: This special condition supplements or supersedes the following sections within Part H of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR 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. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
Page 10 of 13

Permit NCO081621
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: https://www.federalre i ster.gov/documents/2015/10/22/2015-
24954/national-pollutant-discharge-elimination-system-nodes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re -applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may
submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
hitp:Hdeq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
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 11,
Section B. (I1.)(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:
Page 11 of 13

Permit NCO081621

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:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)]
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

Rob,
I was looking at the dates on when the NOV letter was received here at Rocky River. It was sent to our administrative
office first, then sent to me at the plant. We are pushing the 10 days.
If possible can you change the address you have on file to 6400 Breezy LN Concord NC 28025. This is the address of the
Plant. If I need to send in a formal request to change the address please let me know. Nothing against our admin office,
they are just unaware of the time constraints of some items.
If we didn't meet the 10 day limit, there is one letter that was sent by the ORC a month or so ago summarizing the
event pretty well. I attached that letter in my e-mail to Marcia.
Thanks again for the help this morning,
Tim

This is a follow-up to our April 16, 2018 phone conversation informing you that MCWWTP was in violation of
the subject permit's monthly average flow limit of .150 MGD during the previous month. The average flow limit
was .1535 MGD; I became aware of the violation while preparing the March eDMR.
The MCWWTP received 4.5 inches of rain between March 1 and March 31, 2018. In an effort to prevent the
sewage from backing up in the collection system and causing an SSO, I ran a higher volume of flow through the

Subject: NPDES #0081621, Muddy Creek Wastewater Treatment Plant (MCWWTP)
Dear Mr. Scheller:
WOROS
MOORESVILLE REGIONAL OFFICE
This is a follow-up to our April 16, 2018 phone conversation informing you that MCWWTP was in violation of
the subject permit's monthly average flow limit of .150 MGD during the previous month. The average flow limit
was .1535 MGD; I became aware of the violation while preparing the March eDMR.
The MCWWTP received 4.5 inches of rain between March 1 and March 31, 2018. In an effort to prevent the
sewage from backing up in the collection system and causing an SSO, I ran a higher volume of flow through the
Plant. This allowed more water to move through MCWWTP faster while maintaining the other permit limits.
Currently MCWWTP is under construction to increase the treatment capacity to .300 MGD. Construction
started in February and is expected to be completed June 19, 2019.
If you have any questions, please contact me at 704.888.4888, 980.521.8611 and/or via email

This letter is a follow-up to our July 19, 2017 conversation informing you that the Muddy Creek WWTP
(MCWWTP) was in violation of the subject permit for the 15 mg/L BOD limit the week of July 10. Lab
analysis from composite samples taken July 11-13 confirms the weekly average as 20.7 mg/L.
MCWWTP received a toxic loading the evening of July 12. Upon arrival the following day, it was
visually apparent that something irregular had entered the plant. I immediately began measuring the pH
of the aeration basins and found them to be abnormally high (AB 1-8.10, AI32-8.27, A133-7.96, A134-8.24).
I turned down the sodium hydroxide pump speed used for alkalinity addition to the bare minimum so as to
not add anymore alkalinity to the system. Wasting from the clarifiers was also halted to save bug life as
much as possible.
Following is the lab analysis of the effluent composite samples: Date Effluent NH3

The plant is back to normal operating conditions. WSACC has been collecting grab samples from various

This letter is a follow-up to our July 14th conversation informing you that the Muddy Creek Wastewater Treatment
Plant (MCWWTP) was likely in violation of the subject permit's ammonia limit of 12 mg/L for the week of July 10,
2017. Lab analysis from composite samples taken from July 13-16, 2017 confirmed a weekly average of 88.78 mg/L.
MCWWTP received a toxic loading the evening of July 12, 2017. Upon my arrival, it was visually apparent that
something irregular had entered the plant, I immediately began measuring the pH of the aeration basins and found
them to be abnormally high (AB1-8.10, AB2-8.27, AB3-7.96, AB4-8.24). I turned the sodium hydroxide pump speed
used for alkalinity addition down to the bare minimum so as not to add anymore alkalinity to the system.
Lab analysis on the effluent (NH3) composite samples are as follows: 7/13/17 - 60.2, 7/14/17 —181, 7/15/17 —114,
7/16/17 - 58.2 and 7/17/17 - 9.3. July 16/17 started a new week, but I wanted to ensure a downward trend so that the
treatment system was going in the right direction.
On Saturday, July 15, 2017 1 cleaned both disk filters and UV systems (including the bulbs), the step aeration and
effluent stilling well. By afternoon, MCWWTP appeared to be returning to normal, with pH values in the aeration
basins falling within a normal range. On July 17, 1 started to introduce waste activated sludge from the extended
aeration tank into the treatment system for reseeding. As you know, after looking at MLSS under the microscope
there was some live biological activity occurring. I believe the July 13"h pollutant that hit MCWWTP filtered through
and the system is returning to normal.

On July 14, 2017, at 11:17 a.m. this Office received a phone call from Ms. Kim Holt (ORC) to report
plant upset of biological treatment at Muddy Creek Wastewater Treatment facility. The plant upset was
investigated by Roberto Scheller of this Office on July 17, 2017. During the on -site visit a 30-minute
settability test and microscopic examination of Mix Liquors Suspended Solids (MESS) was conducted.
Test indicated that the biological process appeared to be recovering from upset.
It was noted that Ms. Holt is very knowledgeable of treatment plant operations and biological treatment
processes. Due to Ms. Holt's quick response to plant upset the treatment process appeared to be
recovering quickly.
This Office recommends that commercial and industrial users of the collection system be visited to
determine source of plant upset. Collection system users should be reminded that unused and/or outdated
chemicals and cleaning products should be disposed of properly.
The enclosed report should be self-explanatory; however, should you have any questions, please do not
hesitate to contact myself or Roberto Scheller at [phone] or [e-mail].

Dear Mr. Mauldin:
ROY COOPER

Director
On August 08, 2017, Roberto Scheller of this Office conducted an inspection at the subject
facility. This inspection was conducted as a Compliance Evaluation Inspection (CEI) to insure
compliance with permit requirements and conditions. At the time of inspection facility appeared
to be very well maintained and operated; however, an issue with the influent sampler was noted
during the subject inspection. Please check the influent sampler to ensure sampler is located
above all side streams of wastewater, such as backwash water and/or supernatant from sludge
dewatering being sent back to head of plant. Such side streams would skew influent analytical
data and miss represent treatment plant loading and removal rates.
It was also noted that this facility experienced a plant upset that was reported to this Office on
July 14, 2017. It is the recommendations of this Office that headworks be fitted with pH, DO
and ORP probes to detect damaging influents and divert to equalization basin before they reach
treatment units.
We wish to thank you and the operating staff for assistance regarding this inspection.
The enclosed report should be self-explanatory; however, should you have any questions,
please do not hesitate to contact myself of Roberto Scheller at [phone] or
[e-mail].

MOORESVILLE REGIONAL OFFICE
The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge
Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to
report information electronically, instead of filing written paper reports. The rule does not change what
information is required from facilities. It only changes the method by which information is provided (i.e.,
electronic rather than paper -based).
EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their
key milestones, are:
• Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge
Monitoring Reports (DMRs) will begin submitting these reports electronically. If you are currently
reporting your DMR data electronically using eDMR, then you simply need to continue reporting
in the same way as you are now. The key change is that, starting on December 21, 2016,
electronic reporting of DMRs will be required, instead of voluntary.
• Phase 2—Starting on December 21, 2020, regulated entities that are required to submit certain
other NPDES reports will begin submitting these reports electronically. Reports covered in the
second phase include Notices of Intent to discharge in compliance with an NPDES general permit,
Sewer Overflow/Bypass Event Reports, and a number of other NPDES program reports.
Incorporating Electronic Reporting Requirements into NPDES Permits
The NPDES Electronic Reporting Rule requires authorized NPDES programs to incorporate electronic
reporting requirements into NPDES permits beginning December 21, 2015. Under the new rule, the
electronic reporting process supersedes the paper reporting process. According to our files, your NPDES
permit became effective after November 2013, and should contain the requirement to electronically
report your Discharge Monitoring Reports using NC DWR's eDMR system.
In addition to requiring permittees to report information electronically, the rule also requires permittees
to identify the initial recipient for the NPDES electronic reporting data [see 40 CFR 122.41(I)(9)]. Initial
State of North Carolina I Environmental Quality I Water Resources
1617 Mail Service Center I Raleigh, North Carolina 27699-1617
919 807 6300

recipient of electronic NPDES information from NPDES-regulated facilities (initial recipient) means the
entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES Data [see 40 CFR 127.2(b)]. Permittees are required to electronically
submit the required NPDES information to the appropriate initial recipient, as determined by EPA. By July
18, 2016, EPA must identify and publish on its web site and in the Federal Register a listing of initial
recipients by state and by NPDES data group. Once available, you can use EPA's web site to find out or
determine the initial recipient of your electronic submission.
NC DWR has submitted a request to EPA to be the initial recipient for the following NPDES data groups:
1. Discharge Monitoring Reports;
2. General Permit Reports [Notices of Intent to discharge (NOls); Notices of Termination (NOTs)];
3. Pretreatment Program Reports; and
4. Sewer Overflow/Bypass Event Reports
EPA's web site will also link to the appropriate electronic reporting tool for each type of electronic
submission for each state. Instructions on how to access and use the appropriate electronic reporting
tool will be available as well.
For more information on EPA's NPDES Electronic Reporting Rule, visit

It was noted during inspection that the cascade aeration had large amounts of alga growing
on the cascade steps, this alga could sluff off and be taken up by the effluent sampler
resulting in a false reading for TSS, BOD, and Fecal Coliform. It is therefore recommended
that the cascade basin be covered to inhibit sunlight and alga growth.

Muddy Creek classification in BIMS.
Flow is .150 MGD see attached permit page.
Facility is classified as a Grade 3, based on flow shouldn't this system be classified as a Grade 2?

Subject:
I entered the new Back up operator for this facility and noticed they were classified as a 3. The flow for this facility is
only .150 MGD. Don't know why it is listed by permitting as a WW 3. One of the operators they had listed was only a
Grade 1 but BIMS let me enter them anyway. I notified the facility of the error. Contact for this would be Mark
Fowler. The forms were submitted to Raleigh.

MUDDY CREEK WWTP, CABARRUS COUNTY
Dear Mr. Krebs:
This letter is in response to your June 20, 2012 correspondence regarding the Muddy Creek
Wastewater Treatment Plant's (MCWWTP) compliance violations for BOD during the week
ending March 24, 2012 and the ammonia limit monthly exceedence for March, 2012.
To date, there has been nothing to identify the exact cause of the upset, however, several factors
did accelerate and add to the recovery time. The first indicator was the clogging of the disc
filters which resulted in minimal flow exiting MCWWTP. We began our trouble shooting with
the filters, which we cleaned according to the manufacturer's instructions and replaced the
cloths. During this timeframe, MCWWTP was seeing flows indicative of a high flow event.
Basically, the Plant was recycling all or most of the flow back to the Main Pump Station. The
result was a basic wash out of the bio-solids in the aeration basins. Ms. Barbara Sifford
(Mooresville Regional Office) was called and, with her assistance and support, began the process
of rebuilding the bio-mass to an acceptable level. Plant reseeding was performed with return
activated sludge from the Rocky River Regional Wastewater Treatment Plant.
In Ms. Sifford's report (enclosed) you will see that optimal dissolved oxygen (DO) was not being
utilized during this time. In previous years we had been able to maintain compliance with DO's
of less than one at the head of the aeration basin. It has been determined by Ms. Sifford, Mr.
Jeff Lowe (McKim & Creed Engineering Process Control Consultant) and myself that we had
been running MCWWTP at the lowest levels of DO and alkalinity to obtain compliance but not
allow the upset incurred.
We are currently operating MCWWTP with a more controlled approach or with a by -the -book
attitude, as it were. Plans and purchases have been made to assist in maintaining improved
operational control. We have added several different lab analyses to help assist with future
upsets, as part of Ms. Sifford's recommendations. A list of these can be found on the enclosed
DMR's, along with our lab's DO monitoring report which is now being stored in WSACC's lab
data base.

I would like to thank Ms. Sifford for her assistance, not only for the site visit but also for the
large amount of time spent with telephone communications. This was the first and, hopefully,
the last time we will completely lose the bio-mass at any of our facilities. As a positive, it was a
very good learning experience for Ms. Kim Holt who is the newly appointed ORC for
MCWWTP and myself. Under the guidance of Ms. Sifford and Mr. Lowe, I feel we were able to
get the Plant back in compliance as quickly as possible.
If you have any questions or concerns, please contact me at 704-788-4164, ext. 14 or via e-mail

Dear Tim:
June 5, 2012
Subject: Technical Assistance
Muddy Creek WWTP
Cabarrus County
I have enjoyed working with you to solve the treatment plant problems at
Muddy Creek since the initial site visit on March 14, 2012. We have had numerous
phone conversations about the progress until the plant has stabilized and has returned
to compliance. Listed below are the observations and corrective measures taken.
Insufficient dissolved oxygen in the aeration basin.
The blower was operated on a timer but the operational guidelines state a dissolved oxygen level
greater thanl.0 mg/1 should be maintained. After consulting with the engineering firm two
blowers are now operated on the timer to maintain the dissolved oxygen level.
Clarifier solids carryover was clogging filters and excessive backwash cycles
were adding to the plant hydraulics. Also the return rate was lowered to reduce the
internal hydraulics.
This was due to hydraulic issues within the plant and the condition of the MLSS. Temporary fix
was to slow the plant flow down to control the solids carryover to start getting the wastewater
out of the plant.
Many operational changes have been made since this upset was encountered and the
new ORC Kim Holt has gotten first hand on the job training. Each plant is different but the
basics are the same over time each plant can establish its own guidelines for operation.

To determine plant loading more influent samples are to be taken, this data can be used to adjust
the food to microorganism ratio and the alkalinity need to maintain the nitrifying bacteria. The
sludge return rates are proportioned to the influent flow to maintain clarifier solids.
A map of the collection system was evaluated for sampling several trunk lines to determine if
slug loadings are being discharged.
Engineering design was evaluated for clarifier overflow rates and return sludge rates for
hydraulics of the plant.
The alkalinity of the plant effluent is monitored to maintain the nitrification process and caustic
addition was moved to the aeration basin. Polymers were added to assist the solids settling until
the plant MLSS regained good settling characteristics.
The. plant was reseeded to try and establish a nitrifier population, these organisms require a high
mean cell residence time to establish a sufficient population for complete nitrification to occur.
The filters were cleaned and the cloths were evaluated to determine if blinding was causing the
excessive backwash cycles.
Operational parameters to use to optimize the plant:
1. Return rate percentage of influent flow for conventional process is 30%, up to 100% for
extended aeration.
2. Clarifier weir overflow rate should not be greater that 1,105 gpd/linear foot.
3. Aeration basin needs 4.6 parts of dissolved oxygen to oxidize one part of ammonia, and 7.14
parts of alkalinity for every part of ammonia oxidized.
4. To ensure sufficient alkalinity for nitrification the effluent alkalinity should be between
80mg/1 and 100mg/l.
5. Dissolved oxygen in the aeration basin should be above 1.Omg/l and not over 3.Omg/1.
6. Influent ammonia is to be analyzed to determine plant loading.
The data reviewed through the month of April 2012 and discussions about May 2012
indicate that the plant is operating within permit limits at this time. If I can be of any further
assistance please call.
Sincerely,

Marcia,
Here is an electronic copy of the response letter and the original report. Also attached are the DO readings since April. I
did not attach the DMR's, The PDF files are hard to read.
I was only going to send them so you guys could reference to additional lab test we are doing, but you guys have copies
of those, right? I will attach a copy when .I send out the hard copy tomorrow.
I also did not list the DO monitors we are adding that will be on Scada here at the Rocky River plant. We are putting in
four to get continuous monitoring of the aeration basins. I am still working on a way to get away from batch wasting, but
the flow is so low that I can't pump it constantly. It will probably end up being a 3 or four times a day process, with
control here at Rocky River. Oh, the reason for the DO's is so you guys can see we are heading Barbaras advice on
keeping them up.
Anyway I wanted to get this out today.
I hope you had a great 4tn

MOORESVILLE REGIONAL OFFICE
SUBJECT: NPDES NO. NCO081621 NOTICE OF VIOLATION (NOV)
MUDDY CREEK WWTP
CABARRUS COUNTY, NORTH CAROLINA
Dear Mr. Krebs:
This letter is in response to your letter dated January 11, 2012 concerning the NOV at the
Muddy Creek Wastewater Treatment Plant (MCWWTP) for ammonia during the month of October
2011. The monthly limit is 4.0 and the results were 5.2 mg/1.
During the month there were twd, mechanical issues that contributed to this problem. The
return activated sludge pump failed and the replacement pump had to be retrofitted before being
placed into operation. The retrofit took approximately 12 hours which resulted in an excess of
solids building up the clarifiers and the filters. There was also a caustic pump failure at the Main
Pump Station during this time frame. Another attributing factor were two rain fall events of one and
three inches during the following week of the return pump failure.
Both of the mechanical issues were corrected, however, the biomass did not recover with
adequate speed to prevent the violation. While various operational adjustments were made i.e.
wasting rate and diffuser air rates in an attempt to revitalize the nitrofiers, neither were successful.
Reseeding of the plant was considered, but it was not attempted due to the timeline and slow growth
rate of nitrifying bacteria.
We have had two return sludge pumps repaired and ensured that they are compatible so that
the delay of a retrofit will not be required if this problem should arise in the future. We have also
evaluated the solids buildup in the filters and determined that in this situation holding the excess
solids in the filter area versus returning them back to the head of the plant via the drain system is a
better operational practice. Increasing the backwash time of the filters during this type of situation
should allow the filters to operate satisfactory and keep unwanted solids out of the plant until such
time as the filters can be cleaned properly.

RE: Emailing: MCWWTP NOV 2011
Hi Tim,
Both of your responses arrive in Mooresville yesterday; not sure why it took so long for USPS to get us that fecal coliform
response. John Lesley and I took a look at your NOV-NRE response letter and the October DMR for Muddy Creek and we had
some additional questions I was hoping you could answer before we chat with Rob. If you get them to me by early afternoon
tomorrow I can chat with before I am out of the office next week on training in Raleigh. Otherwise it will have to wait until
the following week.
Specifically we were wondering:
1) What day did the RAS pump fail?
2) What day did the caustic pump fail?
3) On what days were the 1-inch and 3-inch storms you noted for the week following the pump failures?
4) Was there any attempt to use a portable pump to facilitate RAS delivery to the aeration basins?
5) Was caustic feed in another local in the plant in lieu of the pump failure at the main pump station?
6) We reviewed the Muddy Creek DMRs for the last year to get a sense of what your ammonia concentrations are usually in
the effluent. We noted there were two instances where the ammonia spiked but immediately returned to "your normal
levels" the next day. We were wondering how this could occur? The dates of elevated ammonia are 11/15/11(17.2 mg/L)
and 4/21/11 (20.4 mg/L).
Any additional information you can provide would be great.
Regards,
Marcia

Marcia,
Please find attached our response to the NOV letter for our Muddy Creek Wastewater Facility that we discussed last week.
The "received" date on the letter from Rob is marked 1-17-12. The date on the letter from the Mooresville office is 1-11-12. It
was sent to Ray Furr at our administrative office address and did not get to the plant until the 17th. I hope this is not a
problem. The certified copy will be in todays mail.
I also have copies of the daily log book entries for this incidence if they are needed.
I did not copy Rob, couldn't find his e-mail.
If there are any problems or if you have additional questions please let me know.
Take care,

Tim

Marcia,
In answer to your questions regarding our Muddy Creek Facility:
1- The RAS pump failed on 10/7/11. Repair time approximately 12hrs due to the aforementioned retrofit.
2- The caustic pump started having problems on 10/24/11. It also was found not pumping on the 25th. Anew pump was
ordered with overnight shipping on the 25th and installed on 10/26/11. 1 am not sure how much of an issue this caused
with as a whole, but without this problem we may have been able to get the ammonia level low enough to bring the
monthly average into compliance.
3-Rain events were 1" on 10/11/11 and 3"on 10/12/11.
4- There was no attempt to use a different pump to facilitate returning while repairs were being made to the RAS pump.
I estimate is would have taken approx. 6 hrs to get our trash pump from RRRWWTP to Muddy Creek and get the lines
connected to start pumping. I confirmed this estimated time with our Maintenance Supervisor. We have insured that
the spare RAS pumps on hand at Muddy Creek will not need any retrofitting. I talked with our Maintenance Manager
about the future replacement time. He estimated 1-2 hours after maintenance personnel arrive on -site. After hours the
time to get to the site should be approximately 1 hr.
5- There was no other Caustic feed while the pump was being repaired. pH for the day was 6.1. We are looking at having
a redundant pump on -site that the operator can change out vs waiting on our maintenance crew to repair the pump. We
have been able to "bounce" back in the past when the pump needed repair, but I think it is still a good idea to have a
spare on hand.
6) As discussed with Marcia on 2-6-12, the spikes are believed to come from a force main that holds sewage for
extended periods and may occasionally be on the septic side. We also see BOD and TSS spikes when the ammonia spikes
occur. The force main in question connects to a housing development that has been slow in building houses over the
past several years. This problem has slowly been improving as houses are added.
As discussed, we are looking into getting the wasting at Muddy Creek into an automatic mode vs the current "batch
wasting" as we have done in the past. With this last upgrade Muddy Creek has been included on the SCADA system that
is monitored at the RRRWWTP. We are still working out a few bugs, but it has shown to be an asset thus far.
If you need copies of the log entries or any have other questions arise please let me know.
Thanks for your patience with getting these questions answered and back to you.

DATE: August 16, 2010
SUBJECT: LOSS OF POWER AT MCWWTP
I received an alarm at around 1 1:30am from the MCWWTP dialer for communications
failure. I arrived at MCWWTP around 12:05pm. After entering the building and looking at
the SCADA I saw that was no data available. I then went to check the effluent and
found that there was no power to the UV system, the effluent flow meter or the effluent
sampler.
I retrieved the bucket of chlorine and dechlor from the lab. I placed chlorine at the head
of the UV system, and the end of the UV system and at the head of the step aeration. I
dropped the dechlor tablets into the effluent.
I called Chris Carpenter and he talked me through a few trouble shooting steps to get
the power back online. When the power would not come on he advised me to call the
other electricians because he was out of town. I called electricians until I got Everett.
After calling Everett and informing him of the situation at MCWWTP, I called Tim Mauldin
to let him know and to inform him that I was using chlorine for disinfection and that from
the time I received the call from the dialer until I got to the plant that we were
discharging for about 45 (minutes) without disinfection.
Between the time that I spoke to Everett and him arriving at MCWWTP and getting power
restored to the UV I used chlorine test strips to get a residual at the effluent. Power was
restored at about 5:00pm. From approximately 12:15pm until 5:00pm chlorine granules
were used for wastewater disinfection and declorination tablets were used to remove
the chlorine before discharging into Rocky River. Between those times I used the chlorine
test strips to monitor the residual at the effluent. I took 4 samples for residual getting
<.1 mg/L (on all tested samples.)
Upon, further investigation we realized that the problem was located in the power line
itself (240 volts line ). The electrical team tried to remove the line but was unable to. They
will run a new line as soon as the line comes in (on order). In the meantime, we have a
temporary line set up to use UV system.

Request for Additional Information
Review of Calculations
(1) Please explain the engineering need for the proposed 38-foot diameter (101,800 gallon)
external equalization (EQ) basin.
Each surge basin on each package plant treatment train is sized at 15,000 gallons, which is
20% flow EQ capacity of each train's 75,000 gpd capacity. The proposed external EQ basin
is sized at 101,800 gallons, which by itself is 68% flow EQ of 150,000 gpd. When the total
EQ volume is considered (external EQ basin + dual surge basins), the combined volume of
131,800 gallons is 88% EQ flow capacity. Even at the projected future design flow of
300,000 gpd, this total EQ volume is 44% flow EQ capacity. These EQ flow capacities (88%
at 150,000 gpd and 44% at the future 300,000 gpd design flow) appear to be excessively
large.
(2) Technical Memorandum No. 5 (Extended Aeration Treatment)
Please document the design for the blower requirements for the extended aeration basins,
particularly related to the design temperature used, showing all air calculations. We note that
historically the existing 75,000 gpd package WWTP tends to lose some nitrification ability
during the colder winter months (see Figure 1 on the last page). We suspect that this might
be because of insufficient DO provided to the aeration basins.
(3) Provide documentation for the existing UV disinfection system, including manufacturer and
model #, the number of banks, the number of modules per bank, the number of lamps per
module, and the treatment/flow rating of each module. Technical Memorandum No. 8 (UV
Disinfection) states that the existing UV system has a peak flow rating of 237,000 gpd.
Please specify if this is all banks operating, or with one (largest) bank out of service.
According to the CG&L Guidelines for UV disinfection, the UV system must be able to treat
to the NPDES permit coliform limits at peak flow with the largest bank out of service. We
note that peak flow is 150,000 x 2.5 = 375,000 gpd.
(4) Confirm that the proposed 150 kW emergency generator is sufficient to run all essential
components of the WWTP.

Review of Plans
(5) Sheet G5 Process Schematic
(a) We note that there is an 8-inch pipe with valve which bypasses the proposed external
EQ basin in addition to the proposed bar screens. Assuming that the external EQ
basin is required as an essential unit, this bypass is not allowed and needs to be
removed.
(b) We note that the design calls for dual 104 gpm pumps to be placed in the proposed
external EQ basin. The external EQ basin needs to either have the following:
(i) Dual pumps which can each pump the peak flow of 260 gpm, or
(ii) an overflow pipe which can deliver any peak overflow (that the proposed
pumps cannot handle) into the influent splitter box.
(6) Sheet C5 Site Yard Piping
(a) Bypass piping around the disk filters is not allowed. Remove the bypass pipe and
isolation valve which allows the filters to be bypassed. See also Sheet M5 (Disk
Filter Plans and Sections), which also should be modified.
(b) Post the pipe invert elevations for the proposed manholes MH-10 and MH- 11.
(7) Sheet M1 External Egualization Basin, Section and Details
(a) Show the proposed mechanical fine screen and the manual bar screen in plan and
section view, at the proposed angle of repose.
(b) Provide construction details for the manual bar screen either on the plans or in the
specifications.
(c) Add elevations to the top and bottom of the bar screen enclosure.
(d) Ensure that, if the automatic bar screen is partially blocked, the backed up water does
not overtop the box enclosure (i.e., raise the walls to have 2 feet of freeboard).
(e) It is not clear if the box enclosure cover will function well, nor why it is necessary to
have a cover. The ORC must be able to inspect the automatic bar screen and the
manual bar screen quickly.
(8) Sheet M3 Modular Treatment Unit Plan
(a) Confirm if there is an overflow pipe from the surge basin to the aeration basins. This
overflow pipe would allow water to flow directly to the aeration basins if the EQ
pumps failed, or if the EQ pumps could not keep up with peak flow. We note that the
proposed EQ pumps are rated at 52 gpm, which is design flow, but less than peak
flow. If there is no overflow pipe, then the EQ pumps should be rated for peak flow.
(b) According to 10-State Standards, 2004 Edition (Chapters 73.23 and 87.2), all sludge
piping shall be a minimum of 6-inch in diameter. Provide engineering justification
for sludge pipes with smaller diameters.

(c) Provide detail section views of the proposed sludge loading station with elevations, in
addition to the necessary specifications.
(9) Sheet E2 Electrical Site Plan
Confirm that there is sufficient overhead night-time lighting for the new structures for the
ORC operators.
(10) Sheet E2 Electrical Site Plan
Confirm that there is sufficient overhead night-time lighting for the new structures for the
ORC operators.
Review of Specifications
(11) Section 11300 Extended Aeration Treatment System
(a) Page 7 of this Section specifies that two (2) 250 CFM blowers will be provided.
Technical Memorandum No. 5 (page 5) states that two blowers will be provided with
an existing third blower to be interconnected as back up. We note that the document
entitled Equipment Specifications for a Dual Train Modular Steel WWTP... (dated 6-
03-2008, which is imbedded in Technical Memorandum No. 5) says on page 4 that
three (3) 250 CFM blowers will be provided.
Please clarify exactly how many blowers will be provided. If an existing 3`d blower is
to be used as back-up, describe how this blower is currently being used at the WWTP,
or if it is available to be used as a back-up blower.
(See Comment #2 on the sizing of the blowers for aeration requirements.)
(b) Page 4 of this Section specifies that the peak sludge recycle rate (RAS) is 44 gpm,
whereas page 13 states that the RAS/WAS pumps shall be dual 55 gpm pumps. The
RAS pumps should be able to pump at 1.2 to 1.5 times design flow (62 to 78 gpm
range).
(12) Section 11311 Raw Sewage Fine Screening Equipment
(a) Part 1.1(C) specifies that the fine screening equipment has a maximum peak flow of
1600 gpm, which equates to 2.3 MGD. Is this correct? We note that Technical
Memorandum No. 3 (Headworks Facility) states that the future peak flow rating of the
screen will be 0.75 MGD.
(b) The specifications listed in Part 1.1(C), particularly the box width, box depth,
maximum upstream water depth with 20% blockage, do not match the dimensions
shown in Sheet MI. Please clarify.
(c) The specifications listed in Part 2.1(A and B), particularly the dimensions of the box
enclosures for the automatic bar screen and the manual bar screen do not match the
dimensions shown in Sheet MI. Please clarify.

(13) Section 11337 Tertiary Disk Filters
Specify that there are two disk filter units. It would be helpful to include in this Section a table
similar to the disk filter specification table found on page 2 of Technical Memorandum No. 7
(Effluent Filtration).
(14) Section 11370 Positive Displacement Blowers
Page 1 of this Section states that the specified blowers are to be used for the external EQ basin
(101,800 gallon) plus the two aerobic digester tanks. Please clarify if this means the 25,000
gallon aerobic digester and the 10,000 gallon sludge holding tank, or does it mean all digester
and holding tanks for both 75,000 gpm package plants. Please document how the blower
rating of 454 CFM was obtained.
(15) WWTP SCADA System
CG&L has been informed by the Engineer that the plans and specifications will be modified to
include a SCADA system for WWTP process monitoring and control. Please include this.

RE: Renewal of the Yadkin/Pee Dee River Basin Associations r�'g oalition
NPDES Permit Modification for Instream Monitoring
NCO081621 Muddy Creek WWTP
Cabarrus County
Dear Mr. Keeter:
For the past ten years, the members of the Yadkin/Pee Dee River Basin Association (YPDRBA) have broadened
understanding of the watershed through water quality monitoring. The Division of Water Quality (DWQ) greatly
appreciates the association's continued support of the monitoring and the time and expertise contributed by its
members.
By this letter the DWQ confirms the waiving of instream monitoring requirements within your individual NPDES
permit in exchange for the YPDRBA's monitoring of the watershed as specified within the renewed
Memorandum of Agreement (MOA) effective August 12, 2008. The agreement identifies the stations,
parameters, and frequency of monitoring required of the association in order to maintain the instream monitoring
waivers for your individual permits. Effluent monitoring requirements are not affected. Should your membership
in the association be terminated, you must notify DWQ immediately and the instream monitoring requirements in
your permit will be reinstated.
All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are
issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the US Environmental Protection Agency.
If you have any questions regarding this letter or the coalition, please contact Jennie Atkins at [phone] or
at [e-mail].

NOTICE OF VIOLATION TRACKING #NOV-2008-PC-0061
Dear Mrs. Allocco:
This letter is in response to the subject Notice of Violation (NOV) received by the Water
and Sewer Authority of Cabarrus County (WSACC) on January 30, 2008. This NOV was issued
after MCWWTP's annual inspection conducted by Mr. Wes Bell and Ms. Donna Hood, of the
Mooresville Regional Division of Water Quality (DWQ) office.
The inspectors found that the influent sampler was set for "time mode" sampling versus
"flow proportionate" sampling. MCWWTP's permit requires that the Plant influent and effluent
be set for flow proportionate sampling. The original influent sampler had been sent out for
repair at the time of the inspection and a temporary unit, an ISCO Glacier portable sampler, was
being used in the interim. The ORC was unaware that the portable unit had flow mode
capability. The ORC also failed to contact the Mooresville Regional office about the sampler
problem.
MCWWTP has ordered a new refrigerated sampler which is the same model as the
original influent sampler, at a cost of $4,800. This was done so the samplers can be directly
swapped out if the original unit should fail again. We feel this will eliminate future problems
and/or possible violations. Please note that all future equipment malfunctions will be reported
immediately to the Mooresville Regional office. This is in an effort to insure compliance as well
as to keep the lines of communication open between WSACC and DWQ.
We would also like to take this opportunity to thank Mr. Bell and Ms. Hood for the
thorough job they did in performing the inspection. While MCWWTP had no effluent violations
during the period in question and we do not feel this incident caused any adverse effects to the

Page Two

receiving waters, thanks to their efforts we realize that this issue could have been rectified by
making a simple phone call. By bringing this problem to light, Mr. Bell and Ms. Hood have
insured that MCWWTP implements measures to avoid potential problems in the future.
If you have any questions or concerns, please feel free to contact the Wastewater
Operations Manager, Mr. Tim Mauldin at 704-788-4164, ext. 14, or me at 704-786-1783.

NOTICE OF VIOLATION TRACKING #NOV-2008-PC-0061
Dear Mrs. Allocco:
This letter is in response to the subject Notice of Violation (NOV) received by the Water
and Sewer Authority of Cabarrus County (WSACC) on January 30, 2008. This NOV was issued
after MCWWTP's annual inspection conducted by Mr. Wes Bell and Ms. Donna Hood, of the
Mooresville Regional Division of Water Quality (DWQ) office.
The inspectors found that the influent sampler was set for "time mode" sampling versus
"flow proportionate" sampling. MCWWTP's permit requires that the Plant influent and effluent
be set for flow proportionate sampling. The original influent sampler had been sent out for
repair at the time of the inspection and a temporary unit, an ISCO Glacier portable sampler, was
being used in the interim. The ORC was unaware that the portable unit had flow mode
capability. The ORC also failed to contact the Mooresville Regional office about the sampler
problem.
MCWWTP has ordered a new refrigerated sampler which is the same model as the
original influent sampler, at a cost of $4,800. This was done so the samplers can be directly
swapped out if the original unit should fail again. We feel this will eliminate future problems
and/or possible violations. Please note that all future equipment malfunctions will be reported
immediately to the Mooresville Regional office. This is in an effort to insure compliance as well
as to keep the lines of communication open between WSACC and DWQ.
We would also like to take this opportunity to thank Mr. Bell and Ms. Hood for the
thorough job they did in performing the inspection. While MCWWTP had no effluent violations
during the period in question and we do not feel this incident caused any adverse effects to the

IF

receiving waters, thanks to their efforts we realize that this issue could have been rectified by
making a simple phone call. By bringing this problem to light, Mr. Bell and Ms. Hood have
insured that MCWWTP implements measures to avoid potential problems in the future.
If you have any questions or concerns, please feel free to contact the Wastewater
Operations Manager, Mr. Tim Mauldin at 704-788-4164, ext. 14, or me at 704-786-1783.

Case No. LV-2007-0075
Dear Mr. Thomas:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount
of $181.50 ($100.00 civil penalty + $81.50 enforcement costs) against the Water & Sewer
Authority of Cabarrus County.
This assessment is based upon the following facts: A review has been conducted of the
self -monitoring data reported for October 2006. This review has shown the subject facility to be
in violation of the discharge limitations found in NPDES Permit No. NC0081621. The
violations are summarized in Attachment A to this letter.
Based upon the above facts, I conclude as a matter of law that the Water & Sewer
Authority of Cabarrus County violated the terms, conditions, or requirements of NPDES Permit
No. NCO081621 and North Carolina General Statute (G.S.) 143-215. 1 (a)(6) in the manner and
extent shown in Attachment A. A civil penalty may be assessed in accordance with the
maximums established by G.S. 143-215.6A(a)(2).
Based upon the above findings of fact and conclusions of law, and in accordance with
authority provided by the Secretary of the Department of Environment and Natural Resources
and the Director of the Division of Water Quality, I, John Lesley, Surface Water Protection
Regional Supervisor for the Mooresville Region, hereby make the following civil penalty

TOTAL AMOUNT DUE
Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken
into account the Findings of Fact and Conclusions of Law and the factors set forth at G.S. 143B-
282.1(b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public
health, or to private property resulting from the violations;
(2) The duration and gravity of the violations;
(3) The effect on ground or surface water quantity or quality or on air quality;
(4) The cost of rectifying the damage;
(5) The amount of money saved by noncompliance;
(6) Whether the violations were committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs
over which the Environmental Management Commission has regulatory authority;
and
(8) The cost to the State of the enforcement procedures.
Within thirty days of receipt of this notice, you inust do one of the following:
1. Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environment
and Natural Resources (do not include waiver form). Payment of the penalty will
not foreclose further enforcement action for any continuing or new violation(s).
Please submit payment to the attention of:
Point Source Compliance/Enforcement Unit

1617 Mail Service Center
Raleigh, North Carolina 27699-1617
No

2. Submit a written request for remission including a detailed justification for
such request:
Please be aware that a request for remission is limited to consideration of the five
factors listed below as they may relate to the reasonableness of the amount of the
penalty assessed. Requesting remission is not the proper procedure for contesting
whether the violation(s) occurred or the accuracy of any of the factual statements
contained in the civil penalty assessment document. Because a remission request
forecloses the option of an administrative hearing, such a request must be
accompanied by a waiver of your right to an administrative hearing and a
stipulation that no factual or legal issues are in dispute. Please prepare a detailed
statement that establishes why you believe the civil penalty should be remitted,
and submit it to the Division of Water Quality at the address listed below. In
determining whether a remission request will be approved, the following factors
shall be considered:
(1) whether one or more of the civil penalty assessment factors in G.S. 143B-
282. 1 (b) were wrongfully applied to' the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage
resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous
violations; or
(5) whether payment of the civil penalty will prevent payment for the
remaining necessary remedial actions.
Please note that all information presented in support of your request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review your evidence and inform you of his decision in the matter of your
remission request. The response will provide details regarding case status,
directions for payment, and provision for further appeal of the penalty to the
Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider
information that was not part of the original remission request considered by the
Director. Therefore, it is very important that you prepare a complete and thorough
statement in support of your request for remission.
In order to request remission, you must complete and submit the enclosed
"Waiver of Right to an Administrative Hearing and Stipulation of Facts" form
within thirty (30) days of receipt of this notice. The Division of Water Quality
also requests that you complete and submit the enclosed "Justification for
Remission Request." Both forms should be submitted to the following address:

County: Cabarrus
Permit Number: NC0081621
Amount Assessed: $181.50
Please use this form when requesting remission of this civil penalty. You must also complete the

the accuracy of any of the factual statements contained in the civil penalty assessment document.
Pursuant to N.C.G.S. § 143B-282. 1 (c), remission of a civil penalty may be granted only when one or
more of the following five factors applies. Please check each factor that you believe applies to your
case and provide a detailed explanation, including copies of supporting documents, as to why the
factor applies (attach additional pages as needed).
(a) one or more of the civil penalty assessment factors in N.C.G.S. 143B-282. 1 (b) were
wrongfully applied to the detriment of the petitioner (the assessment factors are listed in the civil
penalty assessment document);
(b) the violator promptly abated continuing environmental damage resulting from the
violation (i.e., explain the steps that you took to correct the violation and prevent future
occurrences);
(c) the violation was inadvertent or a result of an accident (i. e., explain why the violation
was unavoidable or something you could not prevent or prepare for);
(d) the violator had not been assessed civil penalties for any previous violations;
(e) payment of the civil penalty will prevent payment for the remaining necessary
remedial actions (i.e., explain how payment of the civil penalty will prevent you from performing the
activities necessary to achieve compliance).

General Observations:
The inspection took place the day after a 3.25" rain was recorded in the on -site rain gauge. Solids
accumulation was observed after filtration, in the UV chamber. Mr. Mauldin expressed having operational
difficulty with the facility. Mr. Mauldin was advised to contact Mr. Jerry Rimmer (919.733.0026 x309) of the
Technical Assistance Unit in Raleigh if he continued to have problems.
Record Keeping.-
DMRs for September 2005-August 2006 were reviewed for the inspection. It was noted during the
inspection that the sampling results for influent TSS reported on the July 2006 were inaccurate. Please
submit an amended DMR for July 2006 reflecting the correct influent TSS results. It was also noted that "0"
was incorrectly reported for the BOD monthly average on August 2006. Please submit an amended DMR
reporting the corrected value. Percentage removal rates for TSS and BOD were not included on the
DMRs. Please begin calculating these results and including them on the DMRs immediately.

PERMIT:
The permit adequately describes the WWTP.
RECORDS AND REPORTS:
Records and reports consisting of monthly monitoring reports, chain of custody forms, laboratory
analysis reports, Operator -in -Responsible Charge (ORC)/daily operation and maintenance log, maintenance
log, process control data, calibration data, and sludge records were reviewed during the inspection.
Records and reports appeared to be current and kept in accordance with NPDES permit requirements.
FACILITY SITE REVIEW/OPERATIONS & MAINTENANCE:
All treatment units appeared to be operating properly, and the surrounding grounds were well
maintained. A process control program consists of MLSS, MLVSS, settleability tests, and sludge blanket
measurements. Sludge wasting is based on settleability tests and sludge blanket measurements.
The facility is staffed with one Grade III ORC. Three certified back-up operators have been
designated and are available when the ORC is unable to visit the facility. The ORC was very
knowledgeable of the treatment processes and equipment used at the facility.
LABORATORY:
The Water & Sewer Authority of Cabarrus County (WSACC)/Rocky River WWTP laboratory
(Certification 4177) provides analytical support. The laboratory was not evaluated during the inspection.
The facility performs field analysis under the certification of the WSACC/Rocky River WWTP Certified
Laboratory.
EFFLUENT/RECEIVING WATERS:
The effluent was clear with trace suspended solids and no foam. The facility discharges into the
Rocky River, which is a Class C water in the Yadkin -Pee Dee River Basin. The receiving stream did not
appear to be negatively impacted. The outfall location was accessible.
SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period July 2002 through May 2003. No limit
violations were reported. All monitoring frequencies and sample locations appeared correct. Composite
samples are collected flow proportionately. No instream monitoring is performed due to the facility being
a member of the Yadkin -Pee Dee River Basin Association.
FLOW MEASUREMENT
Effluent flow is measured continuously by an ultrasonic flow meter with totalizer and chart
recording. WSACC Electrical and Instrumentation, annually calibrates the flow meter. The flow meter
was last calibrated on 7/16/03.
SLUDGE DISPOSAL
Sludge is removed by Liquid Waste, Inc. of Charlotte, N.C. and disposed at the WSACC/Rocky
River WWTP.

Dear Mr. Leslie:
This letter is in regard to Muddy Creek Wastewater Treatment Plant's faihne of
the fecal coliform test the week of October 9-13, 2006. The weekly average was
2567.098. On October 16, I contacted your office to report this violation. During the
week it was determined that there was a bio-mass growth in the sand filters, which is
believed to have resulted in the violation.. The filters were cleaned and. extensive
backwashing was done and we feel the problem is under control.
On Thursday, October 19, Donna Hood conducted an annual inspection of the
subject facility and advised that if problems persist we should contact the Technical
Support Group of the Division of Water Quality.
If you have any questions or concerns, please contact me at 704-7884164,

Subject: Renewal Notice
NPDES Permit NCO081621
Muddy Creek WWTP
Cabarrus County
Dear Permittee:
The subject permit expires on October 31, 2003. North Carolina Administrative Code (15A NCAC 2H.0105(e)) requires
that an application for permit renewal be filed at least 180 days prior to expiration of the current permit. If you have already
mailed your renewal application, you may disregard this notice.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than May 4, 2003.
Failure to request renewal of the permit by this date may result in a civil assessment of at least $500.00. Larger penalties may be
assessed depending upon the delinquency of the request.
If any wastewater discharge will occur after October 31, 2003 (or if continuation of the permit is desired), the current
permit must be renewed. Discharge of wastewater without a valid permit would violate North Carolina General Statute 143-215.1
and could result in assessment of civil penalties of up to $25,000 per day.
If all wastewater discharge has ceased at your facility and you wish to rescind this permit, contact Bob Sledge of the
Division's Compliance Enforcement Unit at [phone], extension 547. You may also contact the Mooresville Regional
Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items you must submit with
the permit renewal application. If you have any questions, please contact Valery Stephens at the telephone number or e-mail
address listed below.

In reviewing the Compliance Evaluation Inspection Report I received from your
office on October 12, 2002, it states that I have a deficiency with the Flow Measurement
Section. I believe this an error because of the following:
➢ Mr. Bell and I noticed and talked about the small amount of discharge
going over the weir while not recording the flow on the chart recorder. He
agreed with me that the small amount would be less than ten percent of the
daily flow. Which is allowed in the calibration of the meter. Therefore I
believe that we didn't have a deficiency.
➢ I told Mr. Bell that I would have the flow meter recalibrated again to
double check the accuracy.
If you have any questions, please contact me at [phone].

The facility was last inspected by Wes Bell of this office on November 30, 2001.
PERMIT:
The permit authorizes the continued operation of an existing 0.075 MGD wastewater
treatment system consisting of a pump station, equalization basin, extended aeration, secondary
clarification, tertiary filters, Ultra -violet disinfection, cascade aeration, aerobic residuals digestion,
and aerated sludge holding tank.
The permit for this facility became effective on 1/1/01 and expires on 10/31/03.
RECORDS AND REPORTS:
Records and reports consisting of monthly monitoring reports, chain of custody forms,
laboratory analysis reports, Operator -in -Responsible Charge (ORC)/daily operation log,
maintenance log, process control data, calibration data, and sludge records were reviewed at the time
of the inspections. The records were in-depth and well kept.
FACILITY SITE REVIEW/OPERATIONS & MAINTENANCE:
The subject facility appeared to be well maintained and was in good operational condition
at the time of the inspection. Caustic soda is added at the influent pump station to maintain pH
levels. The mixed liquor appeared to be well mixed and adequately oxygenated. Thirty -minute
settleability tests were performed on each aeration basin (#1 and #2). The values for the #1 and 42
aeration basins were 210 ml/L and 310 ml/L. The supernates were clear with trace pin flocs. The
process control program consists of MLSS, MLVSS, settleability tests, and sludge blanket
measurements. Sludge wasting is based on settleability tests and sludge blanket measurements.
The facility is staffed with one Grade III ORC. A certified back-up operator has been
designated and is available when the ORC is unable to visit the facility. The ORC was very
knowledgeable of the treatment processes and equipment used at the facility.
LABORATORY:
The Water & Sewer Authority of Cabarrus County (WSACC)/Rocky River WWTP
laboratory (Certification #177) provides analytical support. The laboratory was not evaluated during
the inspection. The facility performs field analyses under the certification of the WSACC/Rocky
River WWTP Certified Laboratory.
The pH and DO meters and thermometer appeared to be properly calibrated. The ORC must
insure that all calibration times are documented to verify that the meters are calibrated prior to
analysis.
EFFLUENT/RECEIVING WATERS:
The effluent was clear with no suspended solids or foam. The facility discharges into the
Rocky River, which is a Class C water in the Yadkin -Pee Dee River Basin. The outfall location was
well maintained and accessible. The receiving stream did not appear to be negatively impacted by
the discharge.

SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period October 2001 through June 2002,
inclusive. No limit violations were reported. All monitoring frequencies were correct. Composite
samples are collected flow proportionately. All samples appeared to be properly preserved and meet
the required holding times. No instream monitoring is performed due to the facility being a member
of the Yadkin -Pee Dee River Basin Association. Algae was observed in the effluent composite
sampler tubing. The ORC indicated that the tubing would be replaced.
FLOW MEASUREMENT:
The effluent flow is measured continuously by an ultrasonic flow meter with totalizer and
chart recording. The flow meter is calibrated annually by the WSACC Electrical & Instrumentation
Maintenance Unit. The flow meter was last calibrated on 7/15/02.
At the time of the inspection, a small amount of flow was discharging; however, the flow
meter was not recording a flow. Please be advised that the Permit requires continuous flow
measurement; therefore, all discharges must be measured. In addition, the Permit requires that all
continuous flow measurement devices must be capable of measuring flows with a maximum
deviation of less than + 10% from the true discharge rates.
SLUDGE DISPOSAL:
Sludge is removed by Liquid Waste, Inc. of Charlotte, N.C. and is disposed at either the
WSACC/Rock River WWTP or a CMU WWTP.
SEWER OVERFLOW:
Please be advised that pursuant to Part II, Section E of your NPDES permit, and North
Carolina Administrative Code (NCAC) 15A 2B .0506 (a)(2), any failure of a collection system,
pumping station or treatment facility resulting in a bypass without treatment of all or any portion of
the wastewater shall be reported to the central office or the appropriate regional office (Mooresville
Regional Office 704-663-1699) as soon as possible but no later than 24 hours from the time the
permittee became aware of the bypass. Overflows and spills occurring outside normal business hours
may also be reported to the Division's Emergency Response personnel at 800-662-7956, 800-858-
0368, or 919-733-3300. A written report shall also be provided within five (5) days of the time of
the incident. The report shall contain a description of the bypass, and its cause; the period of the
bypass, including exact dates and times, and if the bypass has not been corrected, the anticipated time
it is expected to continue; and steps taken (or planned) to reduce, eliminate, and prevent recurrence
of the similar events. Any spill that reaches surface waters (i.e. any spill that reaches any water
already present in a conveyance, stream, ditch, etc...) or any spill greater than 1,000 gallons on the
ground that does not reach surface waters must be reported.
An adequate spill response for those spills reaching surface waters should include an
evaluation downstream of the point at which the spill entered surface waters to determine if a fish
kill occurred. The evaluation should also include the collection of upstream dissolved oxygen and
pH measurements for background information and dissolved oxygen and pH measurements at
multiple points downstream of the entry point to document any negative impact. Failure to report
the bypass of collection system, pumping station or treatment facility subjects violators to penalties
of up to $25,000.00 per day per violation.

Dear Mr. Bell:
In reviewing my chart recorder for the month of June 2002, I discovered the
following parameter equipment was not operating correctly:
50050 Flow
Muddy Creek WWTP's flow was not working properly for about one day; the
transducer cone was partly clogged with a hornet's nest and mud wasps. The average
daily flow is about 24,000 gallons per day.
Lynn Bishop spoke to you on Tuesday June 26,2002, about this issue. 1f you have
any questions, please contact me at [phone].

Cabarrus County
Dear Mr. Shive:
In accordance with North Carolina General Statute § 90A-37, the Water Pollution
Control System Operators Certification Commission is required to classify all water
pollution control systems. The rating scale for classification of Biological Water
Pollution Control Treatment Systems, found at 15A NCAC 8G .0302, was adopted by
the Commission to classify water pollution control systems. The classification of a
facility is determined by the permitted flow and the requirement to achieve biological
nutrient reduction.
The Water Pollution Control System Operators Certification Commission hereby
reclassifies the subject facility as a Grade 2 Biological Water Pollution Control
Treatment System.
As required by 15A NCAC 8G .0202 and your permit, you must designate an Operator
in Responsible Charge (ORC) and Back-up Operator of the appropriate type and grade
for the subject facility. Your facility requires a Grade 2 or higher Wastewater
Treatment Plant Operator in Responsible Charge and Grade 1 or higher Back-up
Operator. Please complete and return the enclosed ORC designation form by
February 19, 2001. Failure to designate a properly certified ORC and Back-up
Operator by the above date constitutes a violation of the permit issued for this facility.
This reclassification does not affect current monitorinc reauirements for this facility.
A change in monitoring requirements would require a permit modification.
