Subject: Notice of Violation/Notice of
Recommendation for Enforcement
Violation of G.S. 143-215.1(a)
Unpermitted Discharge of Wastewater
Charlotte Water
Tracking #: NOV-2017-DV-0228
Mecklenburg County
Chapter 143, Article 21 of the North Carolina General Statutes (G.S.) authorizes and directs the
Environmental Management Commission of the Department of Environmental Quality to protect and
preserve the water resources of the State. The Division of Water Resources (DWR) has the delegated
authority to enforce adopted water pollution control rules and regulations.
On July 8, 2017, Charlotte Water reported to this Office that approximately 58,455 gallons of
partially treated wastewater (no disinfection) was discharged into McDowell Creek from the Charlotte
Water/McDowell Creek WWTP earlier on July 8, 2017. Charlotte Water's follow-up written report (5-day
Bypass Report Form) attributed the bypass of the WWTP's UV disinfection system to operation& issues
associated with the backup generators (tripped) during a utility power outage. Charlotte Water had not
applied for or secured a permit to discharge the partially treated wastewater from the Division.
Please be advised that G.S. 143-215.6A provides for a civil penalty assessment of not more than
twenty-five thousand dollars ($25,000.00), or twenty-five thousand dollars ($25,000.00) per day when the
violation is of a continuing nature, against any person who is required but fails to apply for or to secure a
permit required by G.S. 143-215.1(a). Penalties may also be assessed for any damage to the surface waters
of the State that may result from the unpermitted discharge.

NPDES Permit No. NC0036277
McDowell Creek WWTP
Mecklenburg County
Dee Freeman
Secretary
This is to inform you that a review of your toxicity self -monitoring report form for the month of January 2012 indicates a violation of
the toxicity limitation specified in your NPDES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity violation(s). Your
efforts may include conducting a Toxicity Reduction Evaluation (TRE), a site -specific study designed to identify the causative agents
of effluent toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity control options, and confirm reductions in
effluent toxicity. Please be aware that North Carolina General Statutes provide for assessment of civil penalties for violations of
NPDES permit limitations and requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring and Reporting
Requirements. Please note appropriate mailing addresses for submitting your Discharge Monitoring Reports (DMRs) and Aquatic
Toxicity (AT) Test Forms. We encourage you to review this information; if it would be helpful to discuss this situation or possible
solutions to resolve effluent toxicity noncompliance, please contact Mr. John Giorgino with this office at (919) 743- 8441.

WHOLE EFFLUENT TOXICITY MONITORING AND REPORTING INFORMATION
D The following items are provided in an effort to assist you with identifying critical and sometimes overlooked toxicity testing and reporting
information. Please take time to review this information. The items below do not address or include all the toxicity testing and reporting
requirements contained in your NPDES permit. If you should have any questions about your toxicity testing requirement, please contact Mr.
John Giorgino with the Aquatic Toxicology Unit at [phone] or another Unit representative at the same number.
D The permittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement and that toxicity report forms are
appropriately filed,
D The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be entered (with the appropriate
parameter code) on your monthly Discharge Monitoring Report which is submitted to:
North Carolina Division of Water Quality
Central Files
1617 Mail Service Center
Raleigh, NC 27699-1617
IN ADDITION
Toxicity test data (original "AT" form) must be submitted to the following address:
North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
A Toxicity test results shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period
(eg, January test result is due by the end of February).
D Toxicity test condition language contained in your NPDES permit may require use of multiple concentration toxicity testing upon failure of any
single quarterly toxicity test. If the initial pass/fail test fails or if the chronic value is lower than the permit limit, then at least two multiple
concentration toxicity tests (one per month) will be conducted over the following two months. As many analyses as can be completed will be
accepted. If your NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single quarterly test, you
may choose to conduct either single concentration toxicity testing or multiple concentration toxicity testing per the Division's WET enforcement
initiatives effective July 1, 1999. Follow-up multiple concentration toxicity testing will influence the Division's enforcement response.
D Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic toxicity monitoring
requirements (eg, if the testing months specified in your NPDES permit are March, June, September, and December, then toxicity testing must
be conducted during these months).
D If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-June 30, then you must provide
written notification to the Environmental Sciences Section by June 30 that a discharge did not occur during the first six months of the calendar
year.
> If you receive notification from your contract laboratory that a test was invalidated, you should immediately notify the Environmental Sciences
Section at [phone] and provide written documentation indicating why the test was invalidated and the date when follow-up testing will
> If your facility is required to conduct toxicity testing during a month in which no discharge occurs, you should complete the information block
located at the top of the AT form indicating the facility name, permit number, pipe number, county and the month/year of the subject report.
You should also write "No Flow" on the AT form, sign the form and submit following normal procedures.
> The Aquatic Toxicity Test forms shall be signed by the facility's Operator in Responsible Charge (ORC) except for facilities which have not
received a facility classification. In these cases, a duly authorized facility representative must sign the AT form. The AT form must also be
signed by the performing lab supervisor.
D To determine if your AT test forms were received on time by the Division of Water Quality, you may consider submitting your toxidty test
results certified mail, return receipt requested to the Environmental Sciences Section.

Re: Charlotte Water Response to NOV-2017-DV-0228 Unpermitted Discharge of Wastewater
NPDES Permit #NC0036277
McDowell Creek WWTP, Mecklenburg County
Mr. Basinger,
7
Please let this letter serve as Charlotte Water's (CLTWater) formal response to the Notice of Violation and
Recommendation for Enforcement Action (NOV), issued on September 1, 2017 and received by CLTWater on
September 5, 2017. The NOV relates to the unpermitted discharge of partially treated water from the McDowell
Creek WWTP on July 8th, 2017. CLTWater believes that limited information, provided in the initial bypass report that
we submitted to NCDWR on July loth, may have led to NCDWR's decision to issue an NOV. In response, CLTWater
has completed a full investigation of this event and as a result would like to submit additional information for
NCDWR's consideration, Given the information presented herein, CLTWater is requesting that NCDWR rescind this
NOV.
Detailed Summary of Events
On the evening of July 8th, 2017 between 18:10 and 18:30 McDowell Creek WWTP experienced a sudden and
severe thunderstorm that resulted in a widespread and prolonged power outage to the area. Unlike a typical power
outage this storm did not produce an immediate and sustained loss of power that would have allowed the backup
generators to go through their start up procedure and start properly. In this instance, there were several rapid
interruptions in power followed by repeat surges of power returning from the grid. In roughly a ten second period the
plant lost and regained power approximately three times before utility power completely failed. The backup
generators attempted to automatically transfer power several times but were repeatedly shut off by the additional
surges returning from the grid. This condition created a potentially destructive situation for the treatment plant's
generator facility switchgear and automatic transfer switch. As a result, the plant's equipment functioned as
designed, and went into a safety mode to prevent permanent damage.
Charlotte Water 5100 Brookshire Blvd, Charlotte, NC 28216 charlottewater,org
Operated by the City of Charlotte

The operators on duty, realizing that the backup generators were unable to complete their transfer procedure,
responded immediately. The operators quickly recognized the situation (that the generators had gone into safety
mode) and proceeded to follow a manufacturer's procedure to manually clear fault alarms, reset breaker lock outs,
and restart the generators. It is important to note, that the operator's response to this situation was immediate; the
power outage to the area lasted in excess of an hour and a half, but power at the plant was restored in approximately
20 minutes,
15A NCAC 02H ,0124 — Reliability Requirement
CLTWater meets the reliability requirement of its permit (Part II Section C.7.) by having 2 backup generators on site.
Each one of these generators is rated at 2435 Kw with one unit sufficient enough to power the entire plant.
CLTWater also maintains this equipment as required in Part II Section C.2. of our permit. CLTWater conducts bi-
monthly exercises under full load (Attachment A — Generator Run-time Log Sheets) and quarterly preventative
maintenance (Attachment B — Planned Maintenance Checklists). It is important to note that during this event all
equipment functioned properly. The failure to start was by design, in order to protect all electrical components and
parts associated with operation of the generators.
NPDES Standard Conditions - Exception to Prohibition of Bypass and Protection from Enforcement Action
Under our NPDES permit standard conditions, CLTWater is afforded protection from enforcement action if a bypass
is unavoidable to prevent loss of life, personal injury, or severe property damage (Part II C.4.c(1)(A)). Severe
property damage is defined as substantial physical damage to property or damage that may render facilities as
inoperable. This event occurred because the electronics that control the backup generators are designed to shut off
under certain dangerous or destructive conditions that could severely damage them and render the generators
permanently inoperable, Although CLTWater submitted a Bypass report for this event, CLTWater does not believe
this event meets the definition of the term bypass, as defined in the permit. However, to the extent that NCDWR
perceives it as such, no enforcement action is thus warranted.
The repeated power surges coming from the grid prevented the generators from going through a complete startup
sequence and after the third attempt the breakers tripped and the equipment went into a protection mode, This
allowed the operators the opportunity to respond and manually reset the breakers and continue with the startup
procedure thus reducing the amount of partially treated water that was discharged. If the equipment had not tripped
the emergency breakers and gone into protection mode significant damage could have occurred that would have
prevented the manual restart of the equipment and caused the discharge to continue for the full duration of the power
outage. Per our NPDES permit, CLTWater is protected from enforcement action given the occurrence of events in
this specific situation.
No Exceedance of Effluent Limitations
It is important to note that McDowell Creek WWTP does not have a daily maximum fecal coliform limit and would not
have violated any of its effluent limitations during the 20 minutes that the UV lamps were offline. Furthermore, it is
improbable that McDowell's weekly average limit of 200 cfu/100m1 would have been exceeded. Typical results for
treated water upstream of UV disinfection are less than 1000 cfu/100m1. CLTWater confirmed this by sampling
upstream of UV disinfection on September 9th and 10th and results were 560 and 773 cfu/100m1 respectively. In
Charlotte Water 5100 Brookshire Blvd, Charlotte, NC 28216 charlottewater.org
if? operated by the City of Charlotte

contrast, it is typical that most streams in Mecklenburg County have fecal coliform counts in excess of 1000
cfu/100m1 after rainfall events of greater than a half inch. CLTWater can provide data upon request in support of this
conclusion.
Given McDowell WWTP's other fecal coliform results for the week of July 3rd, McDowell WWTP would need a result
of nearly 1.5 billion cfu/100m1 on July 8th in order to have exceeded our weekly average permit limit of 200 cfu/100m1
(see Table 1 below). A result this high is not typical even in raw, untreated sewage. Per EPA's document entitled
"©nsite Wastewater Treatment Systems Manual" typical residential raw wastewater concentrations are between 1
million and 100 million cfu/100m1.

McDowell Creek WWTP has an exceptional history of compliance with all permit limits and conditions. McDowell
WWTP has not had a single permit violation of any kind in over five years. This facility was recently designated as an
Exceptionally Performing Facility by NCDWR. This affords McDowell Creek WWTP a reduced monitoring frequency
for all conventional pollutants including fecal coliform. Although we are only required to sample for fecal coliform
twice a week we still collect five days of samples to demonstrate the effectiveness of our treatment process and our
commitment to protection of public health and the environment.
Summary
This event was an Act of God beyond any reasonable control. CLTWater took all reasonable actions to avoid this
situation, and has met all permit related requirements to provide and maintain reliability in the form of backup power.
CLTWater's equipment functioned properly, and as designed, given this unusual occurrence. CLTWater staff
responded immediately to execute a manual reset and start up procedure to bring equipment back online safely.
Although the power outage lasted in excess of one and a half hours our staffs quick response safely restored power
to the plant in approximately 20 minutes. Additionally, CLTWater is afforded protection in this type of situation under
our NPDES permits standard conditions. Furthermore, no effluent limitations or water quality standards were violated
as a result of this discharge. Given the information presented herein, CLTWater is requesting that NCDWR rescind
this NOV.

This letter is to address several inaccuracies that Charlotte Water (CLTWater) recently discovered on
past eDMR submissions. These were a result of keying 'sample collection time' instead of 'sample end
time' into our data tracking software, On April 4, 2017, Shannon Sypolt (of CLTWater) contacted you to
discuss this matter, and was advised to respond with a formal written letter. Contained in this letter are
the known inaccuracies along with corrected information. CLTWater will also provide an explanation for
how the errors occurred, as well as steps that have been taken to mitigate these types of reporting
inaccuracies in the future.
Background
All of the inaccuracies are for the McDowell Creek Wastewater Treatment Plant (NC0036277), and are
centered on the 'Composite Sample Time' that is reported for both influent and effluent samples at the
facility. None of these corrections will result in significant changes to the overall 24-hour composite
samples used to judge compliance, and thus all of the resulting data is still legally valid and defensible.
CLTWater, in the interest of accuracy and full disclosure, is bringing this information to the attention of the
Division of Water Resources.
The inaccuracies in 'Composite Sample Time' were initially identified by Mr, Joseph Lockler (WWTP
ORC), during normal data review processes. Sample times are manually entered into data management
software by the operations staff at the McDowell Creek WWTP. On occasion, staff have inadvertently
keyed incorrect times from the associated Chain of Custody and entered it into the tracking system.
Specifically, staff have occasionally keyed the 'sample collection time' instead of the required 'sample end
time' into the tracking software. Generally, there are several minutes difference between these two
values. This data is then transferred into the eDMR portal and reported to the Division of Water
Resources.

In order to prevent this type of reporting inaccuracy in the future, McDowell Creek WWTP has made two
key changes:
1, The Chain of Custody form used during sample collection now has critical cells highlighted. This
should help reduce situations where operators accidentally transfer data from the wrong column.
2. A second operator will now be reviewing the times that are manually entered into our data
tracking software. This will be done on a daily basis.
We believe that these two simple steps will help to eliminate this type of problem in the future.

Summary
As shown above, the discrepancies resulting from inadvertently reporting `sample collection time' instead
of `sample end time' data is minimal. The integrity of the data derived from these samples is unaffected,
and the primary purpose of documenting these discrepancies is to demonstrate CLTWater's commitment
to complete and accurate reporting.
Charlotte Water appreciates the open and honest communication that is shared between our offices. If
you have any questions or require further information concerning this letter please feel free to contact
Shannon Sypolt, Water Quality Program Administrator, at [phone] or me at [phone].

Subject: NPDES Electronic Reporting Requirements
McDowell Creek WWTP
NPDES Permit Number: NC0036277
Dear NPDES Permittee:
PAT MCCRORY
DONALD R. VAN DER VAART
SoY reran
S. JAY ZIMMERMAN
Director
,z (). E OFFIC
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
161.7 Mail Service Center I Raleigh, North Carolina27699-1617

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 (NOIs); Notices of Termination (MOTs));
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.

Dear Ms. Jarrell:
In the fall of 2015 and due to the large number of facilities that require electronic submittal, Charlotte
Water requested that the deadline established in the referenced permits be extended. The Division of
Water resources agreed that the establishment of an electronic monitoring protocol for so many facilities
was a significant undertaking. As such, the Division agreed to exercise enforcement discretion until
March 31, 2016 so that Charlotte Water may continue their efforts toward ultimate electronic submi
Since that time, Charlotte Water contacted the Division by letter on February 22, 2016 requesting a
further extension of this deadline. The new request was made due to technical difficulties with setup and
implementation of a new Laboratory Information Management System (LIMS). As a result of the
communications between the Division and the Charlotte Water, it was obvious that you are making a
significant and sustained effort to comply with the electronic permitting requirements in the permits. So,
the Division has decided to extend the timeframe we will exercise enforcement discretion with respect to
the electronic_reporting condition inthe referenced permits.
Thus, pursuant to the requirements of the referenced pennits, no later than June 30, 2016, Charlotte
Water, shall begin submitting discharge monitoring reports electronically using the Division's eDMR
application system for the following permitted facilities:

Due to the time constraints with the implementation of eDMR for numerous facilities, Charlotte Water
requested that the deadline be extended for any NPDES permits that include the eDMR permit condition.
After discussion by phone conference on July 21, 2015, between the Division of Water Resources and
Charlotte Water, it was determined that more time was needed to begin submitting discharge monitoring

In, addition, you had expressed concern about having to submit two paper copies of DMRs. We apologize
for any misunderstanding you may have had. To further clarify, the following guidance can be found on
the eDMR webpage:
At this time, NC DWR is not compliant with the electronic signature component of US EPA's
electronic reporting requirements. As a result, eDMR users will be required to complete their
eDMR submission by printing, signing, and submitting one signed original and a copy of the
eDMR to NC DWR as specified in Part II, Condition D(2) of the NPDES permit. The North
Carolina Division of Water Resources will update eDMR participants when full compliance with
US EPA's electronic reporting requirements is achieved. Please note that until we are compliant
with EPA's requirements, the printed and signed copies of the eDMR reports will need to be sent
to:

Treatment Plant Bypass Report McDowell Creek WWTP
spill report 5.30.15.pdf
Attached is a spill report from the McDowell Creek WWTP with Charlotte Water. The incident occurred this morning
Saturday May 30th, @ 1022hrs. An operator working on clearing an alarm and resetting a bank of UV lamps did not
ensure the backup bank of lamps was up and running. This caused a three minute window when one channel of my UV
system was offline. I will be in the office Monday June 1st and will touch base with you. Additionally, I will fax a copy of
this report to the Mooresville Regional office this afternoon.
Thanks,
Joseph

Mr Bell and Ms. Aloco,
RECEIVED
OF WATER R QUALITY
Find enclosed information you requested to investigate potential water quality and safety violations at
CMUD's McAlpine and McDowells WWTP. My complaints and concerns, began in 2007 with follow up
emails in 2010 and filings with OSHA in 2/15/2012.
McDowell Complaint:
1. SEWER BACKUP. Citizens called and complained about the stream being very cloudy/brownish.
Chief Operator Joseph Lockler and myself opened the effluent gate leading to the stream to
inspect it. That was indeed the case. He sent Joseph Bolick to remove the fallen trees from the
stream which he claimed where impeding the flow and causing the river to be murky.
2. SAMPLING. ORC Pete Goins and Chief Operator Lockler, continually had employees stop
samplers before the 24 hour period to accommodate meetings, training, etc.
3. HARD HATS. Coworkers seldomly wore hard hats before entering hard hat designated buildings
and areas.
McAlpine:
1. CANADIAN GEESE. The geese attack people and trucks during nesting seasons as evidenced by
theutility trucks right door mirror knocked off by geese.
2. DANGEROUS WORKING CONDITIONS. Not having proper shoes when shoveling massive slabs of
grease from the pipes shoved onto the cement making it very slippery when it rained.
3. WORKING IMPAIRED. ORC Kim Neely allowed his protege Todd Howington to get impaired on
the job and even drove him home.
4. HARD HATS. Wearing hard hats in required buildings and locations was never enforced.
5. NOSE/FACE MASKS. They are not furnished or worn when shoveling dry residue/dust
accumulated on top of the dumpster.
6. ELECTRICAL EQUIPMENT. ORC Neely required employees to open and activate electrical
equipment with a posted notice: "DANGER. HIGH VOLTAGE. KEEP OUT". The sign speaks for
itself meaning only certified Electricians should be going into the equipment. Secondly, the
screw pump can be easily activated from the computer and not necessarily by hand.
I hope you can investigate these complaints and right them. Thanks and happy holidays.
You ncerely,
Ngando.

Investigation / Inspection Petition
2/25/2012
By: Theodore (Ted) Ngand©
P.O Box 562501
Charlotte N.C. 28256

Preface:
The city of Charlotte North Carolina's, Charlotte Mecklenburg utilities department (CMUD) has
and continues violating OSHA safety, health standards, rules, and regulations. They
irresponsibly and deliberately provide unsafe working conditions/environment for their
employees and the general public i.e. contactors, suppliers, inspectors, visitors etc. It is in that
regard that we request an investigation of CMUD violations. Our complaints have been
ignored/ scorned at and CMUD's superficial, paltry endeavors , if any, have not corrected or
addressed the safety and health violations. Only continuous investigations and mandatory
enforcements, including fines and penalties will CMUD's feet be held to the fire, forcing them
to comply with OSHA standards by removing threats of imminent danger and serious work
place violations that have caused injury to people like myself and property. My complaints are
predicated on observations and or facts from 2007 to 2010.
INVESTIGATION ISSUES/ TOPICS:
1. Nesting ducks attacking people and vehicles.
McAlpine Creek WWTP, 12701 Lancaster Hwy, Pineville N.C. 28134, has over 40 people
working there on weekdays. Utilities director Barry Gullet, safety coordinator Debra
Beaven, Superintendent Jackie Jarrell and especially plant manager Mr. Sandy Kim Neely
are fully aware, have experienced, Been around, had complaints over many years of
nesting ducks in march — April attacking, injuring people, property, vehicles etc.
Specific incident
A case in point is when the attacking ducks severed and totally knocked off the right side mirror
of a truck (See picture and plant log book to confirm). The nesting ducks are dangerously
located by clarifiers, aeration basins and sample stations from where they attack, chase away
people and vehicles. These are major accidents in waiting which will culminate in a fleeing
individual ending up in a clarifier and drowning or causing a wreck. The nesting ducks are
situated or located:
A. By the catwalk near secondary clarifier # 2 or # 1, the one closest to the north chemical
building.
B. By secondary clarifier # 3, a few feet from the catwalk.
C. By the back or tail end of the north aeration basin opposite/ across from the secondary
clarifier # 15.
D. By sampler walkway across from big blower 10,11, 12 and across from the north
aeration basin.
E. In front of the south aeration basin across from secondary clarifier # 11 and the truck
wasting station.

Additionally the ducks defecate everywhere, causing people to slip, and fall. To experience first-
hand ducks chasing and attacking, go to these locations.
2. EMPLOYEE IMPAIRED, DRINKING, SLEEPING AND CAUSING ACCIDENTS
McAlpine creek manager Kim Neely had practical, first-hand knowledge that employee
Todd Howington, his confidant, protege and favorite heir apparent, drank, slept, and
caused accidents while impaired on the job. Mr. Neely did not follow proper safety
precautionary procedures to protect other employees and the public from Mr.
Howington. He did everything possible to shield, protect, insulate Todd against city,
state, and federal OSHA policies, rules and regulations. For three and half years, I
worked with Todd Howington who drank, slept, acted erratically leaving me to do his
work and mine. I did work that three or more people should be doing especially when it
rained, causing me to sustain injuries which still plague me today. After my left knee
swelled up December 2011 until now, and almost five years since my job related knee
injury, I am resigned to the fact that, I will constantly be on crutches, get cortisone
shots, be bed ridden, wear knee braces, take pain pills/ mediations, unable to carry
weights or work standing up for long periods of time, struggle putting pants on my left
leg, and probably succumb to reconstructive/ replacement knee surgery. I was
mandated by Mr. Neely's rule which he repeated in meetings that everyone working a
shift was responsible and held accountable for the entire facility whether he was
working that section or not. Todd drinking on the job, coming impaired to work,
sleeping and erratic behavior was an open secret. Co-workers who have seen or woken
Todd from sleep, passed out in a service truck or on the bench in the locker room are
numerous including Mr. Neely, Supervisor Ritchie Crump, Jessie Morris, Terry Holt,
Ralph Paul Bucy, David Roberts, Jose Aguilera,etc. Some of these people above will
protect their paychecks and not tell the truth and refuse cooperating like in the 2007
2008 investigation when Mr. Neely called us not to talk to the federal investigators. Mr.
Howington's file might have a trickle of information but I doubt if Mr. Neely
documented, listed and recorded all incidents of Mr. Howington's impairment
infractions. For example, the numerous times he sent Todd home; the truck accidents
he caused; the time Mr. Neely drove Todd home and they got lost, etc.
Specific Incidents:
A. I injured and keep re -injuring my left knee, my hip, back and other foot related
injuries working with Todd under grueling gruesome conditions. I am still bothered
by my swollen left knee as I write which keeps me on crutches and in pain for
months. Standing, sitting, and exercising are not only excruciatingly painful but fast
becoming a luxury of the past. My complaints landed on the cities establishments
and Mr. Neely's deaf ear making me a pariah and subjecting me to threats and

hostility. Mr. Neely equivocated without mincing words in staff meetings, that,
"things will only get worse not better." In a meeting with Todd, Mr. Neely and I by
the screw pumps, I threatened to take my complaints to human resources. Mr.
Neley retorted that if I went downtown to HR, he will be hell to deal with.
Unaffected by this threat, I went down to HR and lodged my complaints. Mr. Neely
was indeed a living hell and nightmare after that. HR arranged a transfer for me to
McDowell.
B. Todd was totally impaired one day. I called Mr. Neely and reported the situation
primarily concerned and fearing for Todd's safety, Co-worker Larry McKinney,
myself, and the facility. Mr. Neely called Todd. Todd got irate. He abandoned his golf
cart and got into a truck to hunt me down. I was by the hypochlorite structure when
Todd driving by the south primaries gunned and revved up his truck engine speeding
towards me. I stopped by the hypochlorite building and sensing danger, I turned
right onto the grass avoiding a collision. Todd not being able to hit me stopped close
to the centrifuge building, jumped out of his truck and angrily barked as he walked
towards me. Sensing he was confrontational and in attack mode, I drove off slowly
from the grass onto the concrete when he was a few yards away from me. I called
Mr. Neely again and told him what had happened. I told him I will continue driving
around the facility avoiding Todd and take refuge with Larry McKinney at the
centrifuge. I was talking to Larry by the bisulfite building facing the centrifuge when
Todd was driving up. I turned my truck facing Synagro so that if Todd was going to
hit me he would hit the passenger side. Larry stopped Todd and asked him what he
was up to. Todd replied "I am looking for Ted" when his truck was parked next to
mine. He was so impaired he did not see my truck. Mr. Neely finally came and met
Todd and I. Todd apologized for speeding towards me and I in turn told him that I
forgave him for deliberately trying to run me over with his truck. I told him that I
reluctantly called Mr. Neely because he was out of control, acting erratically and I
feared for his safety. Surprisingly, Mr. Neely never followed stipulated safety policies
which mandated him taking Todd and myself for drug testing.
3. NO RADIO CONTACT/COMUNICATION
I questioned the safety implications of McAlpine Manager Neely requiring and
instructing centrifuge worker Jack White to take the only Nextel radio they had home on
days like Friday leaving Ralph Paul Bucy who worked alone with no radio and no means
to call for help in case he had an emergency, fell and injured himself. The centrifuge
floors are always wet either with spills from the huge machines or from grease during
maintenance/repair a fact which centrifuge workers Ralph Bucy, Jessie Morris, Jack

white, Larry McKinney, Richie Crump, and Ned Seaman, maintenance mechanic in
charge of the building will confirm. In addition to leaving Paul Bucy with no radio, Mr.
Neely instituted a policy of discouraging us from going to the centrifuge facility, the
maintenance building which he repeated religiously during staff meetings. I ignored Mr.
Neely's edict to my demise and continued checking on the centrifuge workers because it
was the right and safety conscious thing to do.
4. ILLEGAL ELECTRICAL EQUIPMENT OPERATION/ ACTIVATION/ TAMPERING
McAlpine Manager Neely requests, permits unlicensed, non -certified, non -electrician
employees/operators to sometimes tinker, activate, open, operate, access, attempt to
repair and diagnose electrical equipment problems when he knows that it is not an
acceptable safe practice. A case in point amongst others is the screw pump electrical
control station with a do not enter sign posted on it. Mr. Neely still requires employees
to open the electrical station and activate or manually switch the pumps on and off. This
task could be safely and easily done from the scada computer and not put any employee
at risk for a mishap.
SPECIFIC INCEDENT
I further elaborate my point of safety first using employee Roger Fulkenberry's example
which he tells everyone, of his experience trying to fix an electrical problem at Mr.
Neely's request. Roger a plumber by trade attempted to fix the electrical problem and it
resulted in an explosion as he tells it. The experience made him vouch to do anything
Kim asks him to do except touch, open or try to fix an electrical problem again. Roger
may not be forth right or deny his story to protect his paycheck or Mr. Neely.
5. HARD HAT/ HELMET WEARING NOT ENFORCED
At McDowell, McAlpine, Sugercreek at 5301 Closeburn Rd, Charlotte N.C. 28210. The
safety policy stipulating that buildings requiring that hard hats be worn before they are
entered is not enforced. Looking at plants surveillance tapes you will confirm my claim
that McAlpine's Kim Neely, McDowell's Joseph Lockler and Sugarcreek's Pete Goins
violate that safety policy too. If supervisors do not follow mandated safety policies, rules
and regulations, their subordinates cannot be held accountable either.
6. WORKING IN UNSAFE INCLEMENT WEATHER CONDITONS
It is a safety violation when McAlpine's Kim Neely requires employees to perform tasks
in extremely dangerous, very unsafe inclement weather conditions when it is
thundering , lightening, storming, raining, etc. To further compound the problem,

employees have to work around water, lots water in a facility that can treat 64 million to
120 million gallons a day.
SPECIFIC INCIDENT
Backwashing sandfilters in person. This task can be skipped entirely or done
automatically without the physical presence of an employee when it is lightening,
thundering, storming etc. It is reckless disregard for employee safety and dereliction of
duty for Mr. Neely to constantly jeopardize employee well-being/ safety by requiring
them to back wash the Sand filters around millions of gallons of water surrounded by
metallic fixtures which could be a lethal mix.
INVESTIGATIVE FOCUS
To corroborate my claim, consult and check the sand filter backwash sheets, the plant
facility log book on days when there was inclement weather.
7. SMOKING DANGERS
Smoking around McAlpine creek digesters and other buildings, could be lethal and
dangerous with the possibility of an explosion or fire. McAlpine's Kim Neely has been
unable to stop this practice around buildings where gases are produced because the
employees who violate the anti -smoking policy are his favorite henchmen. That group of
5 were made to sign a paper listing the brand of cigarettes they smoked so that the
butts of those cigarettes could be traced to them. It is imperative to label and designate
smoke only sections and post no smoking signs for restricted buildings.
8. SEWAGE BACKFLOW TO STREAM
McDowell Creek 4901 Neck Rd, Huntersville N.C. 28078.
SPECIFIC INCIDENT
Around August 2010, Ms. Johanna Healy cut off the head works bar screens for the
dumpster to be removed. Before she finished, chief operator Joseph Lockler relieved her
of her functions and reassigned her to other duties. Mr. Lockler who assumed control
forgot to reactivate or turn on the bar screen for hours. According to supervisor Goins, it
resulted in the "flow backed up in influent channels potentially causing a sewer
overflow." "Potentially causing," is a misnomer and mischaracterization. It is in the
public's interest to investigate if the backflow incident caused an overflow to the creek,
which is few hundred feet from the headwork bar screen and estimate the volume of
sewage discharged. Simple mathematical calculations by EPA or NCDWQ experts would
ascertain whether the bar screens where off long enough to cause a spill that reached

the stream or not. A contractor who came in afterwards, called to complain that the
alarm siren was loud and louder. Lockler rushed to the headworks, diagnosed the
problem and reactivated the bar screens. This incident probably caused a public and
environmental safety violation on supervisor Goins and chief Lockler's watch.
INVESTIGATIVE FOCUS
Was McDowell's backflow, a public and environmental safety violation as prescribed by
the EPA's national pollution discharge elimination system and the department of water
quality 919-733-0026? Was the incident reported appropriately? Were necessary
measures taken to correct, clean the environment and inform the general public who
fish right where the back flow would have been discharged? Did Supervisor Goins write
up apportioning the blame between the two parties involved or just Ms. Healy?
9. EPA/DWQ NPDES INFLUENT -EFFLUENT SAMPLING VIOLATIONS
McDowell creek's supervisor Elliott 'Pete' Goins and chief operator Lockler constantly
violated the EPA's NPDES requirement that effluent and influent samplers be started,
stopped and allowed to run for 24 hrs before the samples are collected. There are
incidences where they ordered and sent our e-mails/memos for days with scheduled
meeting or training, ordering their subordinates to stop the samplers and collect the
samples before the 24 hr mandated period. We found that troubling and contradictory
to NPDES stipulations because it subjected us as employees to state, federal penalties,
fines, suspensions or revocation of our licenses for knowingly albeit involuntarily
violating EPA/ DWQ mandated rules, regulations and policies. I was very concerned and
spoke up loudly criticizing the practices. I went as far as calling and or writing Mr. Steve
Reid, Paul Rawls, Don Price of DWQ, EPA's Ms. Bonilla Araceli and one of her co-workers
(See exhibits).
SPECIFIC INCIDENT
In September 2010, Chief operator Lockler with supervisor Goins directives/consent
sent an e-mail that Ms. Tamera Byers was giving a presentation at 8 am. He instructed
co-worker Joseph Ihebuzor and I to finish sampling by 8am and be in the meeting room.
The problem was that the effluent and influent samplers where started way past 8am
(8:09am and 8:24am). We felt uneasy, coerced and intimidated to stop the samplers 46
minutes before the 24hr period elapsed. My point of contention remains that, if Mr.
Goins and Lockler thought any meeting was that important, they should have ordered
the samplers started in this case between 6am and 7am and not after 8am as was the
case. Forcing co-worker Joseph Ihebuzor and I to stop the samplers before the 24 hr
period is an EPA NPDES as well as a safety violation which could have been avoided.

INVESTIGATIVE FOCUS:
Review sample collection data sheets from utilities lab at 4222 Westmont drive,
Charlotte N.C. 28217. Also copies of McDowell creek sampling sheets. Get supervisor
Goins and Chief Locklers e-mail records for days when sampling coincided with meeting
and or training.
10. REITRED EMPLOYEE WORKING ILLEGALY
It is a city, DWQ, EPA NPDES violation for McAlpine supervisor Kim Neely to illegally
permit a non -city or retired city employee to work, function in an official capacity as an
agent of, representative conducting business, signing official manifest, log books for and
on behalf of the city of Charlotte.
SPECIFIC INCEDENT
Mr. John Earl Cureton retired many times but Mr. Neely allowed him to keep working
and then unretired him. Mr. Cureton who is in his 70's officially retired again from
McApline creek and the city of Charlotte in December 2009. Supervisor Neely allowed
him to continue working in 2010 in his official capacity as city of Charlotte employee.
Mr. Neely allowed Mr. Cureton to illegally drive the city trucks, use and take home the
city's Nextel telephone which he used to relay instructions about job assignments to Mr.
Cureton. That sparked a major controversy and debate at the facility in which we
questioned Mr. Neely's judgment and the legality of his decisions. It got so heated
especially between Mr. Cureton and Rick Title who officially assumed Mr. Cureton's
duties. Mr. Title felt slighted. We told Mr. Cureton that he was not legally permitted
under city and DWQ policies to represent, sign any official papers, log books, manifest,
drive city vehicles, use of the Nextel telephone, operate city equipment as he was no
longer covered by the city of Charlotte's insurance.
INVESTIGATIVE FOCUS
Mr. Cureton's personnel file to decipher the times he retired/ unretired and correlate it
to the manifests and log books he signed officially on behalf of the city of Charlotte
especially in January and February 2010.
11. OTHER SAFETY CONCERNS
Management and behavioral experts will agree that there is a direct correlation
between a very stressful work place and job performance, job safety, cogent decision
making, sound mental state, good judgment etc. Mr. Neely and others sometime put in

80 hours or more a week, rarely taking or refusing to take vacation time off. As a result,
their being stressed out from job related pressure is manifested in poor decision
making, bad judgment, ill-advised statements, threats, etc. This is evident in the way
Todd Howington's case was handled. Roger Fulkenberry, who after a heated discussion
threatened and invited Scott Zwemer to a fight outside the facility. Fulkenberry and
McConnell putting a black widow spider under my lunch table and numerous incidences
were poorly handled or ignored. There are even more outlandishly bizarre incidents
talked about like the retired Sugarcreek Supervisor asking Regie to enter and clean a
confined space without following proper safety precautions or donning the required
attire/ gear. Regie refused. The supervisor wrote him up and attempted to fire him but
was prevented to do so.

RE: OSH Complaint 208719252
Dear Mr. Jones:
This letter is in response to the complaint concerning alleged health and/or safety hazards at our
establishment.
Item No. Response
Due to the nature of our work environment, nesting geese is a natural occurrence.
Employees have been trained to maintain a distance of 15 — 25 feet from the nesting
areas. This practice keeps the geese calm and does not threaten them.
No records of vehicle damage from geese have been reported.
2. The centrifuge facility is equipped with hard -lined telephone equipment and the
employees are issued mobile communication devices. Employees are required to
maintain communication on a routine basis throughout their shift.
Hazard assessments have been performed on job tasks that require the use of personal
protective equipment. Employees are trained on the use and specific procedures of
wearing personal protective equipment.
4. Our work environment consists of inside/outside work. Employees are trained annually
on the hazards of inclement weather and have the responsibility to seek shelter during
these times. However, there are times when an employee may perform a short -duration
job task relating to the weather event.
No smoking/matches/lighters signs are present at our digester locations. Employees are
trained on the location of the designated tobacco use area and signs are posted.
6. The City does not allow non -qualified employees to repair electrical problems.
Employees are instructed to submit work orders for electrical issues. A full-time licensed
electrical contractor is maintained at the location.

RE: OSH Complaint 208719252-Rebuttal of Ms. D Beaven's Response.
Dear Mr. Neely
As per directives from Mr. R. Jones letter, I wish to categorically, unequivocally, vehemently disagree
with Ms. Beaven's self policing, self regulating assertions that hazardous conditions have been
corrected, no longer exists or satisfactorily abated at CMUD. Her claims are dangerous and
disconcertingly dishonest. I send you a copy of my complaint relevant to OSH with pictorial attachments
to corroborate my claims. It is in that regard that, I am rebutting City of Charlotte's Ms. Beaven's
response and requesting further clarification, review and or reinvestigation.
Ms Beaven's Response # 1.
Rebuttal........See Complaint page 1-2. # 1. I listed specific locations where the ducks nest every year 3-5
feet from the catwalk employees must use daily to do their work. I pleaded that, the OSH investigator
conduct their investigation during the March/April nesting season to see the problem first hand. They
got there after the nesting season when the chicks had hatched or probably did not go there at all. If
"employees have been trained to maintain a distance of 15-25 feet from the nesting areas", as Ms.
Beavens claims, then employees can not use the cat walk to do their work unless they get dropped off
by helicopter or boat. Ms Beaven's claim that " no records of vehicle damages from geese have been
reported", is false and further illustrates how clueless or far removed she is from what is actually
happening on the ground [see picture attachment of damaged truck]. That right side mirror was
knocked off when habitual on the job impaired, accident prone Todd Howington drove it. It is not our
fault that manager Neely protected his protege Todd as he did with the numerous accidents he caused
in a gated area with 15 mph speed limit and kept her in the dark or is it just amnesia on her part?
Ms. Beaven's Response # 2.
Rebuttal.........See complaint page 3 #3. Yes, there are telephones in the centrifuge office. There are no
land line phones in the problem areas downstairs or the first floor where centrifuge machines are
located. Our primary concern is on Fridays when James "Jack" White was ordered to take the only mobil
nextel phone home leaving Paul Bucy who worked second shift alone without a phone to carry
downstairs or the first floor machine area in case of an emergency.

Ms .Beaven's Response # 3.
Rebuttal..........See complaint page 4 #5. PPE training to use equipment like hard hats is one thing; using
the equipment is another. Surveillance video from CMUD will show that, employees do not wear hard
hats entering buildings where hard hats are required all the time. Secondly, making workers shovel dried
waste gathered on top of the compactor conveyor belt without being issued or required to wear a PPE
face mask at McAlpine Creek, is still a grave concern.
Ms. Beaven's Response #4.
Rebuttal..........See Complaint page 4-5 #6. Sand filter backwashing and hosing down the walls is not
critically important or life threatening for the filter but it could for workers during inclement weather
with lightening and thunder. The log books and backwash record sheets can be used to ascertain if the
backwashing was done when it was lightening /thundering .It will be a welcome relief if Ms Beaven can
enforce what she articulated in making sure they "seek shelter" by holding Managers who skirt the rules
and allow employees to work under dangerous conditions accountable.
Ms.Beaven's Response #5.
Rebuttal..........See complaint page 5 #7. Mr. Neely had employees sign and list the type of cigarettes
they smoked. That was done in response to a problem despite the no smoking sign postings and training
over the years.
Ms Beaven's Response # 6.
Rebuttal.........See complaint page 4 #4 and picture attachment. Work orders were a welcome relief but
do not address all our concerns. The screw pump is still activated by employees required to switch them
by hand after opening the door with bold signs "Danger. High Voltage. Keep out". See picture. The
activation can be accomplished from the computer.
Safety, is our common, noble, primary objective. Unfortunately, budgetary cuts threaten to short
change, circumvent and hijack the very essence of that process, instituting self regulation/policing in it's
place. However, we remain hopeful that our complaints will still be fully investigated.

Just an FYI. Night shift is conducting sampling this week due to the staff meeting in the morning. Please be sure to have
the sampling completed by 0800hrs. There is one extra sample t a nee s to a poured up in the morning, it is the BP
3 Filt sample. The carboy should be in the refrigerator in the lab. The sample will be labeled D-BPFilt. The sample will be
l . marked as a composite with no preservative. For the analysis please mark TS. I will be in around 0730 to give you any
assistance you may need, but I don't think you will have any problems.

Weekend and Holiday Update
First as you all know this weekend is a holiday weekend. Monday is Labor Day. Our Labor Day work crew will be Sandi
on 12-8, Jacob on 8-4, and Pat on 4-12. Also, there will be no sampling on Monday due to the Holiday. Sandi you will
_ ! not need to start up the INF and EFF samplers until Monday morning for Tuesday samples. 12-8 will be conducting
sampling next week due to staff meeting on Wednesday. Sandi, I would recommend you start the EFF and INF samplers
3 sometime between 0630 an Q7QQhrs. Don has already prepared the COC sheets for next week, they are in the drawer
of his desk. Jacob has been briefed on any additional sampling questions that may arise, you can speak with him more
this weekend if you need to.
You will notice on the sampling COC sheet there is a new sample. Next week, every day the BFP is running, we will be
collecting a D-BP Filt sample. The sample analysis will be TS. The sample will be poured up in a 250m1 bottle with no
preservatives. We are looking to measure the amount of solids in the BFP filtrate for the possible upcoming use of ferric
chloride in the BP feed for struvite and phosphorous control. Day shift will be responsible for collecting the samples, but
night shift will be pouring them up.
4 Please remember that the monthly staff meeting will be next Wednesday morning. Tamara Byers will be out to give
another presentation on benefits. Please be sure that daily sampling is complete and everyone is ready to go @
6 0800hrs.
We will be running the BFP tomorrow Friday September 3. However we will not be running the press on Monday Labor
Day. Jose h a the r ss a rmai time.
I will be off tomorrow, but will have my phone with me. Have a nice weekend and Holiday.

Subject: Weekend Update 7/22-7/26
All,
Dr,
Today we went ahead and started up the PALL Membrane Building. The building will be in service until late next week
when we will start laying up the racks again for the next quarter.
We are still running AA to the BTBs @ 350gpd each. The sugar water pumps are back on @ lgpm to each BTB. The
alum feed to DB#16 has been cut off, and the filtrate rate has been cut to 50gpm. We did receive a delivery of sugar
today from Choice Beverage.
Channel #3 of the Wedeco System is still in maintenance mode. Energy Erectors came out middle week to look at the
wiring for lamps 9 and 10 for bank A, but have not been back in to make any repairs. Until the wiring is repaired we will
run channel #3 in maintenance mode.
I have been working over the past couple of weeks trying to set and dial in a plant base rate that will prevent the day
tank from becoming too full, yet at the same allow us to streamline running one large blower and not have to worry
about DO issues. From the data I have seen we need to set a base rate between 4.7-4.9 MGD. Please do not,adjust the
base rate beyond these parameters unless the plant flow is way off due to rain or some other event. Night shift is
getting into a habit of knocking the base rate way down and reventing the daft nk from being pumped down in
preparation`for the next da 's flow.
Today we got a notice from the lab that there were issues with the daily sam les nt in this morning. The
temperature of the samples in the bott jes were higher than what is allowed by the state regulations. At this time we do
not know if this will result in a ermit violation for the plant. The lab will run the samples as normal, but an exception
will be noted on the DMR for the month.
Because of this we were advised to restart the INF and EFF samplers this afternoon. The samplers were
restarted around 1230 this afternoon and will run till tomorrow. Sandi, you will need to stop the samplers and conduct
the daily sampling tomorrow. The EFF sampler should be stopped around 1230, and the INF around 1245. We have
already prepared a daily flow sheet, COCs and samples labels for the bottles. Please ice the cooler you are going to use
very very well, and go ahead and place custody seals on the cooler. You can set the cooler either in the filter building lab
or the lab of the admin. building. I will be coming into the plant Sunday morning around 0830-0845 to pick up the
cooler and deliver it to the ESF building. Before 1 take the cooler I will check your sample pictures and we will re -ice the
cooler. The only samples you need to pour up are from the INF and EFF samplers. There will be no raw-2 or BFP
samples.
Next week is going to be a very busy week. First thing Monday morning we will be switching the boilers to diesel fuel, so
that the digester gas line can be vented for the upcoming digester gas line work. Wednesday morning Kemp will be into
the plant to start digging up the gas line, relaying the bed and then putting the pipe back in the ground.
BFP#1 is taken apart and ready to be cleaned. Jacob will be taking care of this next week.
Maintenance will be working early next week to remove the broken anti -vortex plate in zone #5 of BTB#4. For the work
to take place, we will need at some time to stop flow through BTB#4 and drain some water out of zone #5.

Description of collection and treatment systems:
Phone
704-432-2746
Charlotte -Mecklenburg Utilities collects wastewater from an estimated 229,002 connections to households
and businesses throughout the county. Wastewater is collected and directed (via gravity flow supported by
sewage lift stations) to one of Utilities five wastewater treatment plants or the Rocky River Regional Plant
where it is treated. An average of 75.5 million gallons of wastewater is treated and discharged each day
from Utilities plants.
More than 150 employees work to maintain 4,073 miles of collection pipelines and 79 sewage lift stations
throughout the county. The gravity sewer pipes in this system range in size from 8 inches in diameter to 78
inches in diameter.
Each of Utilities' wastewater treatment plants provides primary, secondary and advanced treatment to the
waste stream. Large solid particles and inorganic materials are removed by screening and settling. The
wastewater is treated biologically to remove dissolved pollutants. Disinfection reduces bacterial and
pathogenic materials. Finally, the waste stream passes through sand filters to remove very small particles
that may not have been removed through the settling process. The treated water is released to the stream.

2
How Your Wastewater is Treated
4
1. Primary Treatment
Solid particles & objects are captured in grit screens and primary clarifiers.
2. Aeration/Secondary Treatment
Wastewater is aerated to support growth of microorganisms that remove harmful pollutants.
3. Clarification
Solids and microorganisms settle out in large basins.
4. Advanced Treatment
Wastewater flows through sand filters to remove fine particles.
5. Disinfection
Water is disinfected to remove any remaining pathogens, and then the treated water is released back
into creeks to flow downstream.
II. Summary of System Performance
How did we do?
We are meeting all reporting deadlines and requirements of the federal EPA Administrative Order to
reduce spills, and the EPA approved Capacity, Management, Operations and Maintenance (CMOM)
Programs.
We successfully collected and treated 99.9986 percent of the more than 27 billion gallons of wastewater the
community produced last year. There were 335 sewer spills in our community, a decrease of nine spills
compared to the year before. In fact, the number of spills per 100 miles of pipe continued to decline from
10.9 in 2007 to 8.2 spills in fiscal year 2011.as illustrated by the table on page 4.

tSSos/100 Miles —10-5-Year Moving Average
Utilities works 24 hours a day, 365 days per year to prevent and respond to overflows.
Crews prevent overflows by clearing pipes of tree roots and grease, as well as replacing broken and aging
pipes. Utilities has also increased its efforts to educate customers about properly disposing of fats, oils and
grease (FOG).
Performance Highlights
Charlotte -Mecklenburg Utilities celebrated some important milestones even as it took numerous actions to
prevent overflows and protect water quality through effective wastewater treatment.
• Our wastewater treatment plants met 99.97 percent of all permitted discharge limits.
• All five wastewater treatment plants earned Peak Performance Awards from the National Association
of Clean Water Agencies (NACWA) for the calendar year ending 2010. NACWA Peak Performance
Awards recognize wastewater treatment professionals throughout the nation for protecting the
environment and public health through outstanding treatment and discharge regulatory compliance.
McDowell Creek Wastewater Treatment Plant earned a Platinum Award for a third year, which means
seven consecutive years of perfect compliance. Mallard Creek Wastewater Treatment Plant received a
Platinum Award for six consecutive years of perfect compliance. McAlpine Creek Wastewater
Treatment Plant was awarded its fourth Gold Award in a row for perfect compliance. Sugar Creek
Wastewater Treatment Plant also won a Gold Award for perfect compliance. Irwin Creek Wastewater
Treatment Plant earned Silver Award for five or fewer violations in a one-year period.
• 12.1 miles of sewer pipe and 774 manholes were rehabilitated, repaired or replaced.
* 293 miles of sewer pipe were treated with root control chemicals.
• 1,013 miles of sewer lines were cleaned (including some multiple cleanings in the same location) by
Utilities Field Operations Staff and 86.2 miles of pipe were cleaned by contractors. 12.2 miles of large
diameter pipe was also cleaned by contractors.
• 271 sewer service pipes were replaced.
• 240 cleanouts installed for customers that did not have them or had defective cleanouts.
• 243 miles of rights of way were cleared by Field Operations and contractors to maintain access to
sanitary sewer pipes and to help prevent root intrusions.

Utilities is proceeding with the implementation of a Work and Asset Management (WAM) Program.
that includes deployment of Azteca Cityworks, as well as improved infrastructure management
processes. Functional deployment of Azteca Cityworks for Utilities Field Operations Division will be
complete in fall 2011..Continuous improvement processes are in place and final testing of integration
to the Advantage customer information and billing system are expected to be complete in early
September 2011. Field mobility devices (computers) have been acquired and are being configured for
use by all field crews. Improved asset management processes are being rolled out in tandem with the
system deployment.
Utilities contracted for a physical survey of the entire wastewater collection system, including
inspection of manholes and any exposed piping. This is a multi -year project to collect data that will be
used as part of the foundation of a new geographic information system (GIS) and for hydraulic
modeling that is needed for planning and implementation of the capacity assurance program. The data
being collected includes manhole locations, flowline elevations, pipe sizes, construction materials, and
other information. This survey is approximately 99% complete.
CMUD expanded continuous improvement and optimization efforts utility wide this year. In 2007,
Mallard Creek WRF was the first City of Charlotte government facility to earn the prestigious ISO
14001:2004 certification. The ISO 14000 international certification program focuses on sustainable
optimized operations that first seek to minimize negative impacts on the environment. This first
initiative has helped to lead a refocused effort on instituting best practice standards with ongoing audits
to all operations. Corporate ISO 14001:2004 certification was obtained in May 2010. This corporate
certification currently covers Mallard Creek WRF, McDowell. Creek WWTP, and the Biosolids
program. Obtaining the certification was a collaborative effort among many employees throughout
CMUD. This ongoing effort serves as a continuous improvement model as we move towards greater
sustainability. Additional continuous improvement approaches include seeking certification through
the National Environmental Laboratory Accreditation Program (NELAP) for Lab Services,
participating in the AWWA Partnership for Safe Water, and instituting reliability centered maintenance
practices in our sewer service area.
Utilities continues to collaborate with UNC-Charlotte, Centralina Council of Governments, and CPCC
to assess the feasibility of using problematic fats, oil and grease (FOG) as biodiesel feedstock. This
feasibility study of alternative fuel has been awarded grant funds from the Biofuels Center of NC and
the NC Green Fund. The study is investigating brown grease use as an alternative fuel product to
determine if it will save on fuel costs, avoid disposal costs, and reduce pollution for local governments.
The economic analysis will consider conventional costs and total life cycle impact assessment. Final
reporting is expected by the end of FY2012.
Utilities reclaimed water program continues to operate. Reclaimed water is highly treated wastewater
effluent that is land applied, rather than being discharged into the creek. The Traditions Golf Course is
using up to 500,000 gallons a day during spring and summer time. Mallard Creek Park is using up to
500,000 gallons each month.
There were 79 Wastewater Lift Stations serving our Iow-lying areas. Staff performed 131 preventative
maintenance tasks for a total of 2301 work hours. This does not include twice weekly station checks,
wet well cleaning, emergency generator testing, or emergency/routine repairs.
Plott Road, Kingstree, White Forrest, Quay Road, and Christenbury lift stations were removed from
service due to construction of new gravity lines.
Phase one of the Briar Creek Relief Sewer project was completed. Construction of phase two is
expected to begin fall 2011 or early 2012.
Phase two of the McAlpine Creek. Relief Sewer project was completed and in service on June 13, 2011.
Construction on phase three is expected to begin in spring 2012.
Last year's frequency of sewer spills was below the 5-year average in eight of the twelve months.

City staffinspected grease -handling facilities at 3,744 food service establishments and restaurants (not
including follow-up inspections) to ensure proper grease disposal. The City continued its Grease Free
education program to teach proper disposal of a pipe -blocking menace. Inspectors mailed information
to more than 4,464 customers and handed out information to 10,510 customers in apartments / multi-
family complexes.
Staff conducted more than 19 presentations to more than 1,217 children and adults. Some of the key
presentations were to ten apartment property managers and plumbers. Multiple Earth Day events also
provided opportunities to distribute Grease Free scrapers, pens and other items.
Utilities continues to use door -hangers specifically for maintenance personnel or property manager of
apartment or multi -family complexes. This reinforces best management practices for prevention.
Staff continues to provide bilingual door hangers and promotional items for property managers to give
to new residents.

the strategic communication plan has been received for comments. The final communication
plan is expected to be presented for consideration in September of 2011.
6

Utilities continues to distribute bilingual door hangers to apartment managers and at community
presentations and events. We are also providing pan scrapers and jar openers with the bilingual Grease
Free message.
Along with ongoing media notifications about spills, customers within 1,000 feet of a grease -caused
spill receive a letter alerting them of the spill and how to properly dispose of grease.
Bill inserts in October, November and December mailed (example on next page) to nearly 250,000
customer account holders each month. These also were repurposed as messages on our web site, and
extra inserts were made available at events during those months.
Don't let
plumbing problems
haunt you!
Never pour cooking grease or
other fats and oils down any drain.
They can clog your pipes!
Freeze cooking grease and oils in a
coffee can, or mix liquid vegetable fats
with kitty litter or coffee grounds
in a lidded container. Deposit it in
the trash, or take it to a full -service
recycling center.

Continuing Challenges
Wastewater Collection Challenges
The volume of wastewater that overflowed decreased from 813,044 gallons in fiscal year 2010 to 378,865
gallons in fiscal year 2011. This represents a 53% reduction in volume spilled. The volume of wastewater
that reached surface waters also decreased from 661,883 gallons in fiscal year 2010 to 310,864 gallons in
fiscal year 2011.
The greatest continuing wastewater challenge in this community — and in others across the U.S. — is sewage
overflows. Of the 335 sewer spills that occurred, more than half were due to hardened grease clogging
pipes. Other spill causes included the infiltration of tree roots into pipes, vandalism, general debris, and
broken pipes.

Grease and other blockages that lead to sewer overflows are cleared by Utilities crews, using various
cleaning methods, including mechanical rodders and truck -mounted water jets. If damaged pipe or other
infrastructure is discovered it is repaired. The spilled sewage can sometimes be captured and pumped back
into the sewer system.
Inspection crews and our customers find overflows. Reports of overflows where 1,000 or more gallons
reach surface waters are distributed to the media in an effort to notify the public. A legal notice is posted
when overflows of 15,000 gallons or more reach surface waters. Crews also use door hangers to notify
customers when appropriate.
Charlotte -Mecklenburg Utilities continues its excellent sewage spill response record. Crews responded to
more than 90 percent of the spills within 60 minutes and more than 96 percent of the spills within 120
minutes. The state standard for response is 120 minutes or less.

Utilities has continued to evaluate and refine sewer cleaning operation. Utilities initiated a Consolidated
Cleaning Project in January 2009. Under the direction of the Field Operations Senior Engineer, and using
our SSO data base and GIS, sub -basins with high concentrations of system failures and SSOs are being
identified. Resources from each of the Field Operation Zones are pooled or consolidated in these
problematic sub -basins and deliberate and focused cleaning, inspection, and repair efforts are directed from
the top to the bottom of the sub -basins.
Year over year comparisons of footage maintained through the consolidated approach are not meaningful
this year. Utilities has been production -testing sewer condition testing equipment developed in partnership
with private industry and the University of North Carolina at Charlotte. The equipment uses acoustics to
assess pipe flow conditions and is designed to improve the relevance and effectiveness of maintenance
tasks and reduce wasted resources within the consolidated approach. Resources can be allocated to assets
more likely to require maintenance.
Historically, conditional testing of sewers has consumed as much resource as performing sewer
maintenance; therefore, it has not been economical to conduct testing to verify the need for sewer
maintenance. The acoustic testing equipment being evaluated requires significantly less resources than
maintenance, opening the possibility for economically viable condition -dependent maintenance and
accompanying reduction of unnecessary maintenance. For example, a single area last year required 52,000
feet of sewer cleaning. With the conditional test results, cleaning was reduced to 22,000 feet this year.
30,000 feet of sewer passed conditional testing and required no maintenance. Without the assurance of an
economical conditional test, the additional 30,000 feet of sewer would have to be cleaned. The savings
compound through reduction of quality assurance activities such as CCTV pipeline inspection and improve
the effectiveness of scheduling.
Utilities is encouraged economical conditional test equipment will deliver a demonstrable efficiency
improvement requisite with the ability to move from a time -dependent maintenance schedule to a
condition -dependent schedule.
Utilities has continued to implement its sewer cleaning and maintenance programs consisting of
Predictive Maintenance, Preventive Maintenance, and Corrective Maintenance. The predictive
maintenance, preventive maintenance, and corrective maintenance approach is expected to
reduce SSOs caused by grease, roots, debris, and system defects such as broken pipe and off -set
joints.
Charlotte Mecklenburg Utilities continues to deal with severe budget constraints during these recessive
economic times. During this period, City Council approved an increase in water and sewer rates, and a
new rate methodology. The FY 2012 budget increases the operating budget, and accommodates the hiring
of over 30 Field Operations positions. These additional positions are currently being recruited, and will
help Utilities sustain its maintenance efforts to reduce SSOs.
Utilities tracks, trends, and analyzes the effectiveness of its efforts in reducing SSOs. On a monthly basis
Utilities studies SSOs trends, including: a comparison of the current month's SSO total and SSOs
experienced the same month during the previous year, SSOs per 100 miles of pipe, SSOs versus the five
year average number of SSOs, and SSO volume.
Comparing FY 2010 with FY 2011 SSOs, shows that Utilities has experienced a 4 decrease in total
annual SSOs. Since 2007, Utilities' annual SSO count has reduced as follows:
FY 2007 419
FY 2008 362
FY 2009 358
9

FY 2010 349
FY 2011 335
The reduction in SSOs since the effective date of the Environmental Pr
Administration Order is 84 SSOs annually, or a 20% decrease.
ction Agency
U.S. Environmental Protection Agency (EPA) Administrative Order Update
Charlotte -Mecklenburg Utilities performed a voluntary Management, Operation, and Maintenance (MOM)
Audit in 1999-2000 at the EPA's request. During 2003, frequent heavy rains contributed to Charlotte's
worst year of wastewater overflows. At that point the EPA and Utilities met several times to review the
audit and actions taken since 2000. Utilities also worked with North Carolina Department of Environment
and Natural Resources (NCDENR) to receive a state collection system permit.
In March 2007, the U.S. EPA issued a formal Administrative Order for Charlotte -Mecklenburg Utilities.
This Administrative Order is a regulatory enforcement action that includes a series of steps Utilities must
take to reduce overflows in our community. These steps included paying a civil penalty for past spills and
assuring that certain construction projects would be completed on time.
Charlotte is the first major city in the Carolinas to face EPA enforcement as it relates to overflows. Quite a
few other communities in the southeast, including Atlanta, Mobile and Knoxville have already received a
much more severe EPA enforcement action known as a judicial Consent Decree.
Preventing sewer spills has been a high priority in Charlotte -Mecklenburg for more than a decade. The
administrative order will help further guide our ongoing efforts to address a community problem. We have
increased preventative line maintenance, capital improvements and other programs.
The EPA's and our goal for overflows is zero. Reality is that a system our size will always have some
overflows, but we agree even one spill is too many. Zero spills continue to be our standard and goal in
Charlotte -Mecklenburg.
Wastewater Treatment Plant Challenges
Charlotte -Mecklenburg Utilities five wastewater treatment plants met 99.97 percent of all discharge limit
tests set forth by our NPDES permits but our commitment is 100 percent compliance. Staff continues to
improve maintenance capabilities and overall performance. Major rehabilitation and improvement projects
help maintain compliance. Future upgrades and expansions are being added.
During this fiscal year there were two permit limit violations out of a potential of 7,151 compliance tests.
These violations were exceeding the daily maximum effluent mercury limit at Irwin Creek Wastewater
Treatment Plant on June 21 and June 28. The source of the mercury was found and the discharge of the
excess mercury was stopped. Prior to this point Irwin Creek WWTP's average concentration of mercury
discharged was 10% of the permitted discharge.
Discharge of wastewater that had not completed all of the treatment processes occurred three times. On
each occasion, the wastewater was treated with the exception of the final disinfection process. These
bypasses can be caused by an electrical, mechanical, computer, or operator error. In each case, operators
on -site quickly responded to the bypass and took appropriate cleanup/repair action. No dead fish were
found associated with these bypasses.
Utilities Environmental Management Division operates the System Protection Section to help maintain our
infrastructure. System Protection consists of the Industrial Pretreatment Program and the Commercial
Source Program.
10

The Pretreatment Program identifies, permits, and regulates Industrial Users and others to keep unsuitable
discharges out of the Publicly Owned Treatment Works (POTW). The Commercial Source Program
inspects and regulates Commercial Users, such as food service establishments, to keep unsuitable
discharges such as fats oils and grease out of the POTW.
While industrial and commercial compliance is extremely high in Charlotte -Mecklenburg, identifying
sources of potentially harmful discharges is an ongoing challenge. In fiscal year 2011, the Trunkline
Monitoring and Grease Free programs also continued, enabling Utilities' System Protection and Water
Quality staff to closely observe what industrial, institutional, and commercial customers discharge into the
POTW, identify potential problem areas, and protect the collection system, sewer line workers, treatment
plants and the Environment,
Wastewater Capacity Needs
In 2007 a study of the McAlpine, Irwin and Sugar creek basins was completed to help identify our
community's future wastewater treatment capacity needs through the year 2030. Two of the larger projects
include an expansion at the Sugar Creek Wastewater Treatment Plant and a new regional wastewater
treatment plant along the Catawba River, near its intersection with Long Creek. Both projects will take
years and tens of millions of dollars to complete. Both projects are continuing but at a slower pace due to
lower -than -projected flow rates at our wastewater plants. It is unclear yet whether these patterns will
persist over time such that wastewater capacities may be extended further than we originally projected.
Utilities plans to upgrade Sugar Creek and Irwin Creek Wastewater Treatment Plants which were originally
constructed about 90 years ago.
The sections following this page — Sections HA and 1113 -- detail all spills from the collection system and
plants, along with plant permit limit violations and monitoring and reporting violations. Section HA
includes spills,for the fiscal year ending June 30, 2011 and is separated by month. These include size of
spills, their cause and descriptions of any known environmental impact.
The second section, Section JIB, represents NPDES reporting and monitoring violations and is separated
by plant.

Subject: Engineer's Certification
NPDES Permit NC0036277
Mecklenburg County
Please find enclosed both Engineer's Certifications for the McDowell Creek Wastewater
Treatment Plant Expansion from 6.6 mgd to 9 mgd and 9 mgd to 12 mgd. The original attachment
to the ATC has been modified to match what was actually constructed and placed into service.
Originally the expansion from 6.6 mgd to 12 mgd was going to be achieved via two construction
phases. However, the expansion was completed in one construction project and therefore the
McDowell Creek Wastewater Treatment Plant will begin meeting the requirements for the 12
MGD permit on December 1, 2007.
Please forward this notification to any other required recipient not included on the cc list below.
Contact me at [phone] if you have any questions.

Dear Ms. Allocco:
Charlotte Mecklenburg Utilities is responding to the deficiency noted in the Operations and Maintenance Section of the
Compliance Evaluation Inspection Report dated September 25, 2006. The specific deficiency noted on the inspection on
September 12, 2006, was the following:
"....During the plant walk through, a maintenance sink was observed being allowed to discharge to the storm drain...."
I am reporting with this letter that the sink was re -plumbed the following day, September 13, 2006 to the plant drain system
and completely disconnected from the storm drain system. We believe that the initial connection to the storm drain was done
in error. We will be sure to be more observant of these types of plumbing connections in the future.
Please let me know if there is any other additional information that you need. I can be reached at [phone] ext. 238.
Thank you.

SUBJECT: Advance Notice of Renewal Application
Permit NC0036277
McDowell Creek WWTP
Dear Permittee:
Your NPDES permit for a municipally owned/operated WWTP expires on December 31, 2008. This notice
is being sent to explain the requirements for your permit renewal application.
You are receiving this advance notice because your facility has a permitted flow at or above 1
MGD, or the facility receives industrial [pretreatment] wastewater. If either of these criteria no
longer applies, contact the NPDES Unit before submitting a renewal application.
Federal (40 CFR 122) and state (15A NCAC 2H.O1O5(e)) regulations require that permit renewal
applications be filed at least 180 days prior to expiration of the current permit. Your renewal application is
due to the Division postmarked no later than July 4, 2008. Failure to apply for renewal by the appropriate
deadline may result in a civil penalty assessment or other enforcement activity at the discretion of the
Director.
The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1,
2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The
new application requirements mandate additional effluent testing:
1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal
application. Collect samples for the PPAs in conjunction with sampling for your current
quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA
must include:
• Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals
that are not normally monitored through your NPDES permit.
Y Analyses for total phenolic compounds and hardness.
• Analyses for all of the volatile organic compounds listed in Part D.
• Analyses for all of the acid -extractable compounds listed in Part D.
➢ Analyses for all base -neutral compounds listed in Part D.
Y Analyses for Total Mercury must be performed using EPA Method 1631.
2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with
your renewal application. The tests should be conducted quarterly, with samples collected on the
same day as your current toxicity test. Call the Aquatic Toxicology Unit at [phone] for
guidance in conducting the additional tests.

Page 2
The pollutant and toxicity scans described above must accompany your permit renewal application,
or any major permit modification request. The Division cannot draft your permit without the additional.
data. Any data submitted cannot be over 4 ' years old, and must account for seasonal variation
(samples cannot be collected during the same season each year if collected over multiple years).
PLEASE NOTE: If your permit already contains a requirement for an annual effluent pollutant
scan, additional scans are not required [provided you have conducted at least 3 scans prior to submitting
your application].
If any wastewater discharge will occur after the current permit expires, this NPDES permit must be
renewed. Discharge of wastewater without a valid permit would violate Federal and North Carolina law.
Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day.
Use the checklist below to complete your renewal package. The checklist identifies the items you
must submit with the permit renewal application. If all wastewater discharge has ceased at this facility and
you wish to rescind this permit, please contact me. My telephone number, fax number and e-mail address
are listed at the bottom of the previous page.
Sincerely,
Charles H. Weaver, Jr.
NPDES Unit
cc: Central Files
NPDES File
The following items are REQUIRED for all renewal packages:

issuance of the last permit. Submit one signed original and two copies.
o The completed EPA Form 2A application (copy attached), signed by the permittee or an Authorized
Representative. Submit one signed original and two copies.
o If an Authorized Representative (such as a consulting engineer or environmental consultant) prepares

Authorized Representative (see Part II.B.11.b of the existing NPDES permit).
o A narrative description of the sludge management plan for the facility. Describe how sludge (or other
solids) generated during wastewater treatment are handled and disposed. If your facility has no such
plan (or the permitted facility does not generate any solids), explain this in writing. Submit one signed
original and two copies. This information can be included in the cover letter.

I was informed by Barry Shearin with CMUD that the self imposed moratorium on flows
to the McDowell Creek WWTP will be lifted at the end of the month. He says the
problems they were facing that resulted in the moratorium have been resolved. The
plant now has about 2 MG of excess capacity. Flows from building lots currently
pending approval should not exceed 120,000 gallons. Also, the Town of Huntersville

Subject: Request for remission of Assessment of Civil Penalty, NPDES Permit No. NC0036277, Charlotte Mecklenburg
Utilities, McDowell Creek WWTP, Case No. LV-2003-0537
Dear Ms, Sullins:
Charlotte Mecklenburg Utilities is respectfully requesting a remission or mitigation of the civil penalty that has been assessed
along with the NOV for McDowell Creek WWTP for April 2003.
The McDowell Creek WWTP experienced unusually high flows during the first six months of the calendar year 2003, As you
may be aware, Charlotte Mecklenburg Utilities has been working with Division of Water Quality staff for some time prior to
this year to attain speculative limits in order to expand McDowell Wastewater Treatment Plant. Speculative limits were
received in March 2003 and we are currently working to complete the Environmental Assessment process.
McDowell Creek did experience high flows and exceeded the permit limit of 6MGD for the month of March with a reported
flow value of 6.877 MGD. However, no other permit limit was exceeded for any other pollutant parameter. Additionally, no
parameters were above the speculative permit limits that will be required at 9MGD or 12MGD. I have attached copies of the
DMR pages referring to the effluent results and the speculative limits.
Based on these facts, we do not believe we caused environmental harm to the receiving streams or any threat to public health,
We also understand by requesting this remission that we will not be entitled to an administrative hearing related to this
specific NOV and assessment of civil penalty of S1585.04. The -Waiver of Right to an Administrative Hearing and
Stipulation of Facts" is attached.
Please let me know if there is any other additional information that we can provide to assist you in reviewing this request. I
can be reached at [phone] ext. 238. Thank you for your consideration.

Dear Mr. Bean:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount of
$1585.04 ($1500.00 civil penalty + $85.04 enforcement costs) against Charlotte -Mecklenburg
Utilities.
This assessment is based upon the following facts: A review has been conducted of the
discharge monitoring report (DMR) submitted by Charlotte -Mecklenburg Utilities for the month
of April 2003. This review has shown the subject facility to be in violation of the discharge
limitations found in NPDES Permit No. NC0036277. The violations are suminarized in
Attachment A to this letter.
Based upon the above facts, I conclude as a Twitter of law that Charlotte -Mecklenburg
Utilities violated the terms, conditions or requirements of NPDES Permit No. NC0036277 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 ofEnvironment and Natural Resources and
the Director of the Division of Water Quality, I, D. Rex Gleason, Water Quality Regional
Supervisor for the Mooresville Region, hereby make the following civil penalty assessment against
Charlotte -Mecklenburg Utilities: &VA

For 1 ofthe one (1) violation of G.S. 143-
215.1(a)(6) and NPDES Permit No. NC0036277, by
discharging waste into the waters of the State in
violation of the permit monthly average effluent limit
for Flow.
$ 1500.00 TOTAL CIVIL PENALTY
$ 85.04 Enforcement costs.
$ 1585.04 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 violation;
(2) The duration and gravity of the violation;
(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 violation was 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 must 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
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

2. Submit a written request for remission or mitigation including a detailed
justification for such request:
A request for remission or mitigation is limited to consideration of the
reasonableness of the amount of the penalty and is not the proper procedure for
contesting the accuracy of any of the statements contained in the assessment letter.
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 there are no factual or legal issues in dispute. You
must execute and return to this office the attached waiver and stipulation form and
a detailed statement which you believe establishes whether:
(a) 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;
(b) the violator promptly abated continuing environmental damage resulting
from the violations;
(c) the violations were inadvertent or a result of an accident;
(d) the violator had been assessed civil penalties for any previous violation;
(e) payment of the civil penalty will prevent payment for the remaining
necessary remedial actions.
Please submit this information to the attention of:
Ms. Coleen Sullins
Water Quality Section Chief
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Please note that all information presented in support of a request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review the information during a bimonthly enforcement conference and inform you
of his decision in the matter of the remission request. His 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. Please be advised that the Committee cannot
consider information that was not part of the original remission request considered
by the Director and therefore, it is very important that you prepare a complete and
thorough statement in support of your request for remission.
OR

Submit a written request for an administrative hearing:
If you wish to contest any statement in this assessment letter, you must request an
administrative hearing. This request must be in the form of a written petition to
the Office of Administrative Hearings and must conform to Chapter 150B of the
North Carolina General Statutes. You must:
File your original petition with the
Office of Ative Hearings
6714 Mail Service Center
Raleigh, North Carolina 27699-6714
and
Mail or hand -deliver a copy of the petition to
Mr. Dan Oakley, General Counsel
Department of Environment and Natural Resources
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Failure to exercise one of the options above within thirty days, as evidenced by a date
stamp (not a postmark) indicating when we received your response, will result in this matter being
referred to the Attorney General's Office with a request to initiate a civil action to collect the
penalty.
Please be advised that any continuing violation(s) may be the subject of a new
enforcement action, including an additional penalty. If the violations are of a continuing nature,
not related to operation and/or maintenance problems, and you anticipate remedial construction
activities, then you may wish to consider applying for a Special Order by Consent. If you have
any questions about this civil penalty assessment or a Special Order by Consent, please contact
the Water Quality Section staff of the Mooresville Regional Office at 704/663-1699.

Subject: Request for remission of Assessment of Civil Penalty, NPDES Permit No. NC0030210, Charlotte Mecklenburg
Utilities, Mallard Creek WWTP, Case No. LV-2003-0487
Dear Ms. Sullins:
Charlotte Mecklenburg Utilities is respectfully requesting a remission or mitigation of the civil penalty that has been assessed
in conjuction with the NOV for Mallard Creek WWTP for March 2003.
As you may know, the Mallard Creek WWTP has been under construction to expand the plant from 8MGD to 12MGD. The
construction of this expansion was supposed to be completed over a year and half ago. Most of the major process units have
been completed but due to issues with the contractor, the project has not been signed off as "substantially complete".
Mallard Creek did experience high flows and exceeded the permit limit of 8MGD for the month of March with a reported
flow value of 9.438 MGD. However, no other permit limit exceedences for any other pollutant parameters were experienced.
Additionally, no parameters were above the permit limits that will be required at 12MGD. These permit limits are attached for
your reference.
Based on these facts, we do not believe we caused environmental harm to the receiving streams or any threat to public health,
We also understand by requesting this remission that we will be entitled to an administrative hearing related to this specific
NOV and assessment of civil penalty of $1585.45. The "Waiver of Right to an Administrative Hearing and Stipulation of
Facts" is attached.
Please let me know if there is any other additional information that we can provide to assist you in reviewing this request. I
can be reached at [phone] ext. 238. Thank you for your consideration.

Dear Mr. Bean:
This letter transmits a Notice of Violation and assessment ofivil penalty in the amount of
$1585.45 ($1500.00 civil penalty + $85.45 enforcement costs) against Charlotte -Mecklenburg
Utilities.
This assessment is based upon the following facts: A review has been conducted of the
discharge monitoring report (DMR) submitted by Charlotte -Mecklenburg Utilities for the month
of March 2003. This review has shown the subject facility to be in violation of the discharge
limitations found in NPDES Permit No. NC0030210. The violations are summarized in
Attachment A to this letter.
Based upon the above facts, I conclude as a matter of law that Charlotte -Mecklenburg
Utilities violated the terms, conditions or requirements of NPDES Permit No. NC0030210 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, D. Rex Gleason, Water Quality Regional
Supervisor for the Mooresville Region, hereby make the following civil penalty assessment against

TOTAL CIVIL PENALTY
Enforcement costs.
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 violation;
(2) The duration and gravity of the violation;
(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 violation was 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 must do one of the following:
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
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

2. Submit a written request for remission or mitigation including a detailed
justification for such request:
A request for remission or mitigation is limited to consideration of the
reasonableness of the amount of the penalty and is not the proper procedure for
contesting the accuracy of any of the statements contained in the assessment letter.
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 there are no factual or legal issues in dispute. You
must execute and return to this office the attached waiver and stipulation form and
a detailed statement which you believe establishes whether:
(a) 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;
(b) the violator promptly abated continuing environmental damage resulting
from the violations;
(c) the violations were inadvertent or a result of an accident;
(d) the violator had been assessed civil penalties for any previous violation;
(e) payment of the civil penalty will prevent payment for the remaining
necessary remedial actions.
Please submit this information to the attention of:
Ms. Coleen. Sullins
Water Quality Section Chief
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Please note that all information presented in support of a request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review the information during a bimonthly enforcement conference and inform you
of his decision in the matter of the remission request. His 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. Please be advised that the Committee cannot
consider information that was not part of the original remission request considered
by the Director and therefore, it is very important that you prepare a complete and.
thorough statement in support of your request for remission.
OR

Submit a written request for an administrative hearing:
If you wish to contest any statement in this assessment letter, you must request an
administrative hearing. This request must be in the form of a written petition to
the Office of Administrative Hearings and must conform to Chapter 150B of the
North Carolina General Statutes. You must:
File your original petition with the
Office of Administrative Hearings
6714 Mail Service Center
Raleigh, North Carolina 27699-6714
and
Mail or hand -deliver a copy of the petition to
Mr. Dan Oakley, General Counsel
Department of Environment and Natural Resources
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Failure to exercise one of the options above within thirty days, as evidenced by a date
stamp (not a postmark) indicating when we received your response, will result in this matter being
referred to the Attorney General's Office with a request to initiate a civil action to collect the
penalty.
Please be advised that any continuing violation(s) may be the subject of a new
enforcement action, including an additional penalty. If you have any questions about this civil
penalty assessment, please contact the Water Quality Section staff of the Mooresville Regional
Office at 704/663-1699.

Dear Mr. Bean:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount of
$2585.04 ($2500.00 civil penalty + $85.04 enforcement costs) against Charlotte -Mecklenburg
Utilities.
This assessment is based upon the following facts: A review has been conducted of the
discharge monitoring report (DMR) submitted by Charlotte -Mecklenburg Utilities for the month
of April 2003. This review has shown the subject facility to be in violation of the discharge
limitations found in NPDES Permit No. NC0030210. The violations are summarized in
Attachment A to this letter.
Based upon the above facts, I conclude as a matter of law that Charlotte -Mecklenburg
Utilities violated the terms, conditions or requirements of NPDES Permit No. NC0030210 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, D. Rex Gleason, Water Quality Regional
Supervisor for the Mooresville Region, hereby make the following civil penalty assessment against

TOTAL CIVIL PENALTY
Enforcement costs.
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 violation;
(2) The duration and gravity of the violation;
(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 violation was 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 must do one of the following:
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
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
2. Submit a written request for remission or mitigation including a detailed
justification for such request:
A request for remission or mitigation is limited to consideration of the
reasonableness of the amount of the penalty and is not the proper procedure for
contesting the accuracy of any of the statements contained in the assessment letter.
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 there are no factual or legal issues in dispute. You
must execute and return to this office the attached waiver and stipulation form and
a detailed statement which you believe establishes whether:
(a) 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;
(b) the violator promptly abated continuing environmental damage resulting
from the violations;
(c) the violations were inadvertent or a result of an accident;
(d) the violator had been assessed civil penalties for any previous violation;
(e) payment of the civil penalty will prevent payment for the remaining
necessary remedial actions.
Please submit this information to the attention of:
Ms. Coleen Sull"tns
Water Quality Section Chief
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Please note that all information presented in support of a request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review the information during a bimonthly enforcement conference and inform you
of his decision in the matter of the remission request. His 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. Please be advised that the Committee cannot
consider information that was not part of the original remission request considered
by the Director and therefore, it is very important that you prepare a complete and
thorough statement in support of your request for remission.

OR
Submit a written request for an administrative hearing:
If you wish to contest any statement in this assessment letter, you must request an
administrative hearing. This request must be in the form of a written petition to
the Office of Administrative Hearings and must conform to Chapter 150B of the
North Carolina General Statutes. You must:
File your original petition with the
Office of Administrative Hearings
6714 Mail Service Center
Raleigh, North Carolina 27699-6714
d
Mail or hand -deliver a copy of the petition to
Mr. Dan Oakley, General Counsel
Department of Environment and Natural Resources
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Failure to exercise one of the options above within thirty days, as evidenced by a date
stamp (not a postmark) indicating when we received your response, will result in this matter being
referred to the Attorney General's Office with a request to initiate a civil action to collect the
penalty.
Please be advised that any continuing violation(s) may be the subject of a new
enforcement action, including an additional penalty. If the violations are of a continuing nature,

Laboratory Exception Report
Reference: Mallard Creek WWTP
Mr. Jerome Lucky, ORC
On April 7, 9 and 10, 2003, field personnel were unable to access the effluent sampling point, due
to flooding. As a result, temperature, pH, ©© and conductivity are not reported for this day.
Additional field monitoring was conducted on Saturday, April 12th to compensate for the missed
day. It was possible to collect a fecal coliform sample on each of the three regular monitoring
events, as the collection site for that sample, which is just after disinfection, was not affected by
flooding. A fecal coliform sample was also collected on the 12'h to correspond with the other field
parameters.
Should you have any questions or require further information, please do no hesitate to call me at

Utilities,' Mallard Creek. WWTP, Case No. LV-2003-0536
Dear Ms. Sullins:
Charlotte Mecklenburg Utilities is respectfully requesting a remission or mitigation of the civil penalty that has been assessed
in conjuction with the NOV for Mallard Creek 'WTP for March 2003.
As you may know, the Mallard Creek WWTP has been under construction to expand the plant from BMGD to I2MGD. The
construction of this expansion was supposed to be completed over a year and half ago. Most of the major process units have
been completed and are operating. However, due to issues with the contractor, the project has not been signed off as
"substantially complete" to date.
For this reason we are requesting remission of penalty related to exceeding the flow limit of 8MGD.
We also understand by requesting this remission that we will not be entitled to an administrative hearing related to this
specific NOV and assessment of civil penalty of S 1585.45. The "Waiver of Right to an Administrative Hearing and
Stipulation of Facts" is attached.
Please let me know if there is any other additional information that we can provide to assist you in reviewing this request. I
can be reached at [phone] ext. 238. Thank you for your consideration.

FINDINGS AND DECISION
AND ASSESSMENT OF
CIVIL PENALTIES
Acting pursuant to delegation provided by the Secretary of the Department of
Environment and Natural Resources and the Director of the Division of Water Quality, I, Coleen
H. Sullins, Deputy Director of the Division of Water Quality (DWQ), make the following:
FINDINGS OF FACT:
A. Charlotte -Mecklenburg Utilities (CMU) operates the 6.0 million gallon per day
McDowell Creek Wastewater Treatment Plant ( P) in Huntersville, North
Carolina, which is located in Mecklenburg County.
B. CMU was issued NPDES Permit No. NC0036277 for the treatment and discharge
of wastewater from the McDowell Creek WWTP on March 9, 2001, effective
April 1, 2001, with an expiration date of February 28, 2005.
C. On January 18, 2003, Mecklenburg County Water Quality Program (MCWQP)
staff observed a discharge of untreated wastewater from a sewer collection system
manhole at the McDowell Creek WWTP to McDowell Creek and Mountain
Island Lake. Mountain Island Lake are Class WS-IV waters of the State in the
Catawba River basin.
D. CMU had no valid permit for the above -described activity.
E. The water quality standard for fecal coliform bacteria within Class WS-IV waters
shall not exceed a geometric mean of 200 colonies per 100 ml (200/100m1), based
upon five consecutive samples examined during a 30 day period, nor exceed 400
colonies/100m1 in more than 20% of the samples examined during a such period
as set forth in 15A NCAC 2B.0211(3)(e).

F. From. January 19, 2003 through January 28, 2003, MCWQP staff collected sixty-
nine (69) surface water samples from McDowell Creek and Mountain Island Lake.
Twenty-one (21) samples exceeded 400 colonies/100m1. This is 30%© of the
samples.
G. NPDES Permit No. NC 0036277 contains the following relevant condition:
Part 11, Section C, 2: Proper Operation and Maintenance. The Permittee shall at
all times properly operate and maintain all facilities and systems of treatment and

H. A Notice of Violation dated February 18, 2003, was issued to CMU by the
Mooresville Regional Office (MRO) of DWQ concerning the January 1e
discharge at McDowell Creek WWTP.
On March 13, 2003, MRO received a written response dated March 6, 2003 from
CMU regarding the Notice of Violation. . CMU's response stated that the
wastewater discharge was the result of an operator closing a valve on the force
main from the influent pump station. The response also stated that the "spill was
clearly the result of mistakes made in the operation of the plant."
The cost to the State of the enforcement procedures in this matter totaled $300.52.
Based upon the above Findings of Fact, I make the following:
CONCLUSIONS OF LAW:
A. Charlotte -Mecklenburg Utilities is a "person" within the meaning of G.S. 143-
215.6A pursuant to G.S. 143-212(4).

The degree and extent of harm to the natural resources of the Stat
health, or to private property resulting from the violation:
0
he public
No harm has been measured or quantified; however, discharges of untreated wastewater
can impact the waters of the State by causing violations of water quality standards and
criteria which are established to protect aquatic life and the designated uses of the
receiving stream (i.e., recreation, agriculture, water supply, etc.).
2. The duration and gravity of the violation:
The bypass lasted approximately 8.5 hours resulting in the release of 2.5 MG of raw
sewage to McDowell Creek and Mountain Island. Lake, Class WS-IV water in the
Catawba River Basin. The discharge was the result of operator error. The operator
closed a valve on the force main from the influent pump station, which caused sewage to
backup and discharge from a sewer manhole. See attached response from CMU dated
March 6, 2003.
The effect on ground or surface water quantity or quality or on air quality:
Surface water samples were collected that contained fecal coliform levels in excess of
6000 col./100 ml. in Mountain Island Lake. See attached sample results and map. It is
unlikely that the violation would have an effect on either groundwater quality or quantity
or on air quality.

Dear
This is in response to your February 18, 2003, Notice of Violation and Recommendation for
Enforcement relative to a January 18, 2003, incident at the subject wastewater treatment plant.
That unfortunate incident was the result of errors made in the plant operation. Upon discovery of
the spill, Charlotte Mecklenburg Utilities took immediate actions to stop the spill, contain the
spillage, clean up the impacted area, and notify adjacent residents. The McDowell Creek
WWTP is a very high -performing plant and takes great pride in its past performance. This
incident was the result of human errors that were unexpected and that have caused us much
dismay.
On Saturday, January 18, 2003, an above ©round, 2" water main carrying treated effluent (non -
potable water or "NPW") that is used internally within the McDowell plant split. The operator
on duty operated valves and successfully stopped the water from gushing from the split at
approximately 10:00 a.m. This NPW is also used to operate hydraulic control valves on the
pumps in the influent pumping station. The operator noticed that although these pumps were
running, no wastewater was being pumped. The operator believed the reason the pumps were
not pumping was related to the reduced NPW water supply to the control valves since he had just
gotten the leak stopped in that system. The operator worked for a considerable time to try to
ensure that the control valves were in fact open, but was still unable to get any output from the
pumps. At approximately 4:00 p.m., the operator called the plant supervisor who immediately
traveled to the plant. Upon his arrival, the supervisor observed the then -flooded influent purr p
station. He called a local pump rental company who quickly transported portable pumps and
temporary piping to the plant site and began setting it up to by-pass pump from the influent
pump station to the preliminary treatment works at the top of the plant. Utilities wastewater
collection crews had also responded to the spill and were working to set up filter fabric dams in
the stream to try to capture as much of the solids as they could. By this time, Utilities' Director,
Deputy Director, Wastewater Treatment Superintendent, Instrumentation and Controls
Supervisor, and additional operators, and mechanics were also on -site, along with several

consulting engineers who are familiar with the plant. Mecklenburg County Water Qual
Program staff had also been contacted and arrived on site.
Utilities also notified our own water treatment plant and those of Gastonia and Mount Holly who
are the only other cities who withdraw drinking water from Mountain Island Lake. All of these
intakes are several miles downstream of the spill location. None of the water plants reported any
difficulties due to the spill.
At that time, it was not clear why the pumps were not moving wastewater. Utility technicians.
were hard at work conducting pressure and equipment tests to diagnose the problem. Others
were studying record drawings of the plant, trying to find solutions. At the same time, the
operator on duty was undergoing rigorous de -briefing to re -trace his steps and actions from
earlier in the day. All of this effort led to the conclusion that the most likely cause of the
problem was the failure of a large gate valve on the 24" force main outside of the influent
pumping station. The decision was made to try to re -activate an old section of smaller force
main (abandoned during a previous expansion of the plant) to by-pass the suspected valve. That
work resulted in restoration of flow to the head of the plant and an end to the overflow at 9:30
p.m. There was still concern that the re -activated line may not be able to sustain peak influent
flows, so the temporary pumps and piping were left in place.
On Sunday, an on -site contractor, Utilities staff, and our consultants developed a repair plan and
mobilized / prepared to uncover the suspected valve (more than 10' deep, surrounded by other
piping, and in unstable soil) for repair on Monday. Also on Sunday, Utilities issued a news
release, gave several media interviews, and contacted two Mountain Island Lake Covekeepers by
telephone to inform them of the situation.
On Monday, the valve was uncovered and found to be in good shape and not the source of the
problem.
Continued diagnostics, investigation, and questioning of the operator on Monday finally revealed
that the operator had in fact closed a valve on the force main from the influent pump station
while trying to stop the NPW leak. Prior to this time, the operator had reported (repeatedly) that
he had not operated any valves in that area of the plant. It also turned out that this same valve
was actually re -opened on Saturday night as part of the effort to re -activate the abandoned force
main.
Utilities has taken appropriate actions relative to the operator's failure to notify supervisors
sooner that a problem existed and for not being forthcoming in reporting valves that he had
operated that day.
Utilities calculated the volume of wastewater spilled by comparing the hourly flow records from
the same time period one week earlier. According to data recorded at the plant, water levels in
the wet well reached the top (crown) of the 36" influent pipe into the plant at 1:00 p.m. From
that point, flow continued to back up in the pipe and manholes until it overflowed from manholes
upstream of the plant. The level recorder in the wet well does not operate when the water level is
above thispoint, so it is not possible to determine exactly when the water level reached the

elevation of the lowest upstream manhole. At 9:30 p.m., after the flow through the force main
had been restored, the water level in the wet well had dropped to the crown of the pipe as the
backup subsided. Therefore, the spill was reported to have occurred and the volume spilled wa
calculated based on the hours between 1:00 p.m. and 9:30 p.m. At 1:00 p.m. on Saturday,
January 18, the flow rate into the plant was almost exactly the same rate as that time on the
previous Saturday, thereby confirming that using the previous week flow data was appropriate.
In addition to the state -required public notifications of a spill of this magnitude, Utilities placed
door hanger spill notices with the closest residents. Because of the time of year, extreme cold
weather (temperatures that day were between 10° and 30° F), cold lake water temperatures, and
the resulting unlikelihood that anyone was in body contact with the lake water, Utilities did not
notify the nearest lake front properties, who were nearly a mile away from the spill area. In
hindsight, we should have notified those residents as well.
Utilities' response to spills is to take immediate actions and to call on any needed resources to
stop the spill and clean up the area. In this case, we brought in temporary pumping and piping
(S28,404), tried to capture solids in the stream ($3,133), and used a contractor already on site to
recover and inspect the suspected valve (S8,720). We also mobilized Utilities staff (recall that
this was a holiday weekend) ranging from additional operators to the Utilities Director and
consultants to help manage, diagnose, and resolve the problem.
Utilities crews also worked to remove debris and to clean up the areas impacted by the spill.
Mecklenburg County Water Quality Program staff collected samples from the stream and from
various locations in McDowell Cove and Mountain Island Lake. Samples were collected on
several days following the spill to determine how widespread the impacts were. County data
showed that the effects of the spill were fairly limited, with the greatest impacts in the stream and
in the rear of the McDowell Creek Cove of the lake. The impacts to the stream and the cove
were primarily elevated fecal coliform levels and within less than two weeks there was no
evidence of the spill. We are not aware of any fish killed by this incident.
To avoid similar problems in the future, Utilities is checking and confirming existing valve
markings / labeling and providing additional markings where needed for all critical valves on tlh�
plant site. A large schematic of the plant piping and valves is being mounted on a wall within
the plant showing the valve labels so that an operator would not need to search out and interpret
plant construction drawings to identify valves (note that in this incident the operator did not
check plant drawings to try to determine which valve should be operated — this work is being
done as a precaution and to further aid staff in operating the plant). Plant operators have been
strongly reminded that they need to call for assistance inunediately if they encounter unusual
operating problems. Utilities has also reviewed internal procedures for placing door hangers and
notifying residents on spills of this type. In addition to these immediate actions, Utilities has
plans to construct flow equalization facilities at this plant as part of an upcoming expansion
project. Similar facilities at other Utilities plants have been utilized to avoid spills when
problems have occurred at influent pumping stations or at other critical locations within the
plant.

We have attached an aerial photo of the plant area that is marked to show where the spill
occurred and which residents were notified via door hangers.
As detailed above, this spill was clearly the result of mistakes made in the operation Qf the plant.
When the operator reported the problem to others, Utilities' staff moved quickly and decisively,
brought in all needed resources, stopped the spill, cleaned up the area and performed
notifications. The spill was not due to the failure of any mechanical or electrical system nor to
the lack of existence of proper operating procedures. Even so, we are reviewing and reinforcing
procedures and systems that could help prevent similar future incidents. We are very sorry that
the incident occurred.
Please let me know if you have any questions.

Discharge of an estimated 2.5 million gallons of untreated
wastewater to McDowell Creek
Charlotte MecklenburgUtilities
January 18, 2003 at 6:59 p.m: Mr. David Rimer of the Mecklenburg County Water
Quality Program (MCWQP) received a telephone call from Mr. Earle Peigler of Charlotte
Mecklenburg Utilities (C advising that over one million gallons of untreated
wastewater had been released from the McDowell Creek Wastewater Treatment Plant
into McDowell Creek. The spill was reported as currently active.
January 18 at 7:04p.m.: Mr. Rimer contacted Mr. Rusty Rozzelle, Water Quality
Program Manager, and advised him of the situation. Mr. Rozzelle informed . Rimer to
immediately conduct an onsite investigation of the spill to ascertain the environmental
impacts and obtain as much information as possible concerning the cause of the spill and
the actions being taken to eliminate the discharge. Mr. Rozzelle also asked Mr. Rimer to
advise CMU to issue a press release and notify the residents of McDowell Creek Cove as
well as the operators of the downstream drinking water intakes.
January 18 at 7:06 p.m.: Mr. Rimer received a telephone call from Jackie Jarrell, head of
CMU's wastewater treatment facilities, asking for contact infoiination on the water
intakes on Mountain Island Lake, where McDowell Creek discharges into. Mr. Rimer
provided this information. Mr. Rimer strongly advised Ms. Jarrell to issue a press release
and to notify those who lived near the spill as well as the operators of the water intakes.
January 18 at 8:00 p.m.: Mr. Rimer met Earl Peigler of CMIJ at the McDowell Creek
Wastewater Treatment Plant. They walked to where the sewage overflows had occurred
and observed large quantities of sewer solids accumulated around two manholes
immediately upstream of the plant but no active overflow was observed. The sewer
discharge had entered McDowell Creek which, at the time of the investiaation, was
slightly turbid and carrying a large volume of water, possibly due to runoff from the
recent snow storm. A mild sewer odor was detected around the creek. CMU had
contacted Hepaco, an environmental cleanup company, to perform containment and

law:444,gorsio,
f'17'
cleanup. A boom was observed across McDowell Creek just upstream of the Neck Road
bridge to contain floatables. No sewer solids were observed in McDowell Creek. At the
time of the investigation, CMU advised that a valve had failed at the plant causing a loss
of pump pressure resulting in the discharge of effluent from the manholes.
Mr. Rimer contacted Mr. Rozzelle and briefed him on the results of his investigation.
Mr. Rozzelle infoinied Mr. Rimer that tomorrow the two of them would collect water
samples in the creek, cove and lake to ascertain the extent of environmental damage. Mr.
Rozzelle asked Mr. Rimer to make the necessary arrangements with the lab and to secure
the necessary sample bottles, boat, etc.
January 19. 2003: Mr. Rozzelle and Mr. Rimer conducted a thorough evaluation of
surface waters downstream of the sewer discharge by performing water quality
monitoring activities at 20 sites in the creek, cove and lake, including immediately
adjacent to all drinking water intakes. The attached map shows the locations of these
monitoring sites and results. All 20 sites were sampled for fecal coliform bacteria. In
addition, field analyses for conductivity and dissolved oxygen were performed for the
lake sites. The field data indicated that dissolved oxygen levels in the cove and lake
were withinacceptable levels and no negative impacts to aquatic life were observed.
Conductivity levels were elevated at sites 1, 2 and 3 (see attached map) with higher
levels recorded on the bottom of the lake. An inspection of the plant revealed that all
discharges had been discontinued and that sewer solids had been removed from the spill
area. There was also evidence that lime had been applied around the spill area for
disinfection.
January 20, 2003: Laboratory results were received indicating that elevated fecal
coliform bacteria levels were confined to McDowell Creek and McDowell Creek Cove.
January 1, 2003: Mr. Rimer and Mr. Buetow of MCWQP conducted water quality
monitoring activities on the creek, cove and lake to assess the continuing impacts from
the spill. Thirteen samples were collected in the lake and eight were collected in the
creek. Some of the monitoring sites differed from those on the previous Sunday in order
to better assess the spread of the contamination. Also, a smaller boat was used on
Tuesday which allowed sampling in the shallower areas of the cove. Field analyses were
also perfoiined at all lake sites. A total of 8 samples were collected in the creek around
the spill area (see attached map).
January 21. 2003: CMU issued a press release stating that the spill was the result of
human error and not a mechanical problem as previously reported.
January 22. 2003: Lab results were received for the January 21 samples indicating that
the sewage had moved through McDowell Creek Cove and reached the main channel (see
attached map).
January 28. 2003: Mr. Rimer and Mr. Buetow collected fifteen samples in the lake and
eight samples in McDowell Creek around the spill area.

January 29, 2003: Lab results received. All fecal results were low and below MCWQP
action levels (see attached map).
February 10, 2003: State notice of violation and recommendation for enforcement was
mailed to the Mooresville Regional Office.

Plant spill caused by human error
HUNTERSVILLE — Saturday's sewer spill at the McDowell Creek Wastewater Treatment Plant
was the result of human error and not a mechanical problem as previously suspected.
Charlotte -Mecklenburg Utilities first believed the source was a pipe blockage caused by a broken
underground pipe valve. As repairs took place through the holiday weekend it was determined
the valve was not broken. Upon further investigation it has been determined that another valve
had been inadvertently closed Saturday to fix a broken water line.
That shut -down of a key valve caused a blockage and backup in the line that delivers wastewater
into the plant for treatment. An estimated 2.5 million gallons of wastewater spilled from manholes
outside the plant over several hours Saturday as Utilities staff worked to stop the overflow and
set up a temporary bypass pumping system before returning the plant to normal operation.
"Our account has tumed out differently after interviewing plant employees and recreating the
actions that were taken during the day on Saturday," Utilities Director Doug Bean said Tuesday.
Some of Saturday's spillage was contained but most flowed into McDowell Creek. State and
local water quality agencies were quickly notified Saturday and will receive corrected information
today. The Mecklenburg Water Quality Program took water quality samples up and down the
creek and in Mountain Island Lake as a precaution on Sunday. The results show elevated fecal
coliform numbers in the McDowell Cove, but no fish kill or other significant environmental
impacts have been identified. The public drinking water supply remains safe.
Along with state and local water quality officials, Utilities staff notified other cities located along
Mountain Island Lake. Property owners along Neck Road and in close proximity to the spill were
notified.
McDowell Plant treats an average of 5 million gallons of wastewater per day and serves
northwestern Mecklenburg County. The plant has an excellent performance history. It has
recently eamed national awards for protecting the environment through compliance with its
discharge permit.
"This spill was the result of operator errors," Bean said. "Our organization will learn from it and
we are very sorry it happened. But in spite of this event I want to re-emphasize that our
employees are hardworking and qualified professionals with a proven record of providing safe
drinking water and protecting our environment through day -in, day -out treatment of the
communitys wastewater."

Dear Mr. -34CftS 044:,
This is in response to your February 18, 2003, Notice of Violation and Recommendation for
Enforcement relative to a January 18, 2003, incident at the subject wastewater treatment plant.
That unfortunate incident was the result of errors made in the plant operation. Upon discovery of
the spill, Charlotte Mecklenburg Utilities took immediate actions to stop the spilit, contain the
spillage, clean up the impacted area, and notify adjacent residents. The McDowell Creek
WWTP is a very high -performing plant and takes great pride in its past performance. This
incident was the result of human errors that were unexpected and that have caused us much
dismay.
On Saturday, January 18, 2003, an above ground, 2" water main carrying treated effluent (non -
potable water or "NPW") that is used internally within the McDowell plant split. The operator
on duty operated valves and successfully stopped the water from gushing from the split at
approximately 10:00 a.m. This NPW is also used to operate hydraulic control valves on the
pumps in the influent pumping station. The operator noticed that although these pumps were
running, no wastewater was being pumped. The operator believed the reason the pumps were
not pumping was related to the reduced NPW water supply to the control valves since he had just
gotten the leak stopped in that system. The operator worked for a considerable time to try to
ensure that the control valves were in fact open, but was still unable to get any output from the
pumps. At approximately 4:00 p.m., the operator called the plant supervisor who immediately
traveled to the plant. Upon his arrival, the supervisor observed the then -flooded influent pump
station. He called a local pump rental company who quickly transported portable pumps and
temporary piping to the plant site and began setting it up to by-pass pump from the influent
pump station to the preliminary treatment works at the top of the plant. Utilities wastewater
collection crews had also responded to the spill and were working to set up filter fabric dams in
the stream to try to capture as much of the solids as they could. By this time, Utilities' Director,
Deputy Director, Wastewater Treatment Superintendent, Instrumentation and Controls
Supervisor, and additional operators, and mechanics were also on -site, along with several

consulting engineers who are familiar with the plant. Mecklenburg County Water Quality
Program staff had also been contacted and arrived on site.
Utilities also notified our own water treatment plant and those of Gastonia and Mount Holly who

ACTION TAKEN.......:
Saturday 1-18-03 6:59 pm David Rimer received telephone call from Earle Paigler of CMU advising MCWQP that McDowell
:reek WWTP had spilled over one million gallons of raw sewage into McDowell Creek. The spill is active and CMU does not
,et have everything under control.
7:04 pm David Rimer called Rusty Rozzelle, WQ Program Manager, and advised him of the spill.
7:06 pm David Rimer received telephone call from Jackie Jarrell, head of CMU's wastewater treatment facilities, asking for
:ontact information on the water intakes on Mountain island Lake, where McDowell Creek discharges into. Provided
equested information to Mrs. Jarrell.
8 pm David Rimer met Earl Paigler at the McDowell Creek WWTP. We walked to where the sewage overflows had
)ccurred. Observed two manholes in the sanitary main where there were large amounts of sewer solids surrounding the
nanholes with no active overflow. The overflow had entered an unnamed tributary to McDowell Creek which, at the time of
ny observation, was flowing clear with a large volume possibly due to runoff from the recent ice snow storm. McDowell Creek
gas moderately turbid in appearance with a mild smell of raw sewage in the air.
CMU earlier had called out Hepaco to perform containment and cleanup. A boom was already across McDowell Creek just
pstream of the Neck Road bridge to catch any floatables. Observed no solids in McDowell Creek.
The latest word from CMU was that a valve had failed and the plant had lost pressure and influent causing the overflows.
Briefed Rusty Rozzelle on my findings. We will be taking water samples in Mountain Island Lake tomorrow as well as
amples in McDowell Creek. Strongly advised CMU to make a press release and to notify those who lived near the spill.
Arranged with the Charlotte Mecklenburg Police Department to use their boat for the lake run.
-19-03 David Rimer and Rusty Rozzelle took fifteen samples in Mountain Island Lake from inside McDowell Creek Cove to
:MU's Water Intake to Gastonia`s & Mt. Holly Intake near MI dam. Took five samples in McDowell Creek around the spill
)cation.
-20-03 Lab results showed that high fecal levels was inside McDowell Cove but not near any housing.
-21-03 David Rimer and Dave Buetow conducted a special MI lake run. Collected fifteen samples in MI Lake. Also
Dllected eight samples in McDowell Creek around the spill.

McDowell Creek Wastewater Treatment Plant, 4901 Neck
Rd., Huntersville, N.C.
Discharge of an estimated 2.5 million gallons of untreated
wastewater to McDowell Creek
Charlotte Mecklenburg Utilities
January 18, 2003 at 6:59 p.m.: Mr. David Rimer of the Mecklenburg County Water
Quality Program (MCWQP) received a telephone call from Mr. Earle Peigler of Charlotte
Mecklenburg Utilities (CMU) advising that over one million gallons of untreated
wastewater had been released from the McDowell Creek Wastewater Treatment Plant
into McDowell Creek. The spill was reported as currently active.
January 18 at 7:04 p.m.: Mr. Rimer contacted Mr. Rusty Rozzelle, Water Quality
Program Manager, and advised him of the situation. Mr. Rozzelle informed -MT Rimer to
immediately conduct an onsite investigation of the spill to ascertain the environmental
impacts and obtain as much infoiniation as possible concerning the cause of the spill and
the actions being taken to eliminate the discharge. Mr. Rozzelle also asked Mr. Rimer to
advise CMU to issue a press release and notify the residents of McDowell Creek Cove as
well as the operators of the downstream drinking water intakes.
January 18 at 7:06 p.m.: Mr. Rimer received a telephone call from Jackie Jarrell, head of
CMU's wastewater treatment facilities, asking for contact infoiniation on the water
intakes on Mountain Island Lake, where McDowell Creek discharges into. Mr. Rimer
provided this information. Mr. Rimer strongly advised Ms. Jarrell to issue a press release
and to notify those who lived near the spill as well as the operators of the water intakes.
January 18 at 8:00 p.rn.: Mr. Rimer met Earl Peigler of CMU at the McDowell Creek
Wastewater Treatment Plant. They walked to where the sewage overflows had occurred
and observed large quantities of sewer solids accumulated around two manholes
immediately upstream of the plant but no active overflow was observed. The sewer
discharge had entered McDowell Creek which, at the time of the investigation, was
slightly turbid and carrying a large volume of water, possibly due to runoff from the
recent snow storm. A mild sewer odor was detected around the creek. CMU had
contacted Hepaco, an environmental cleanup company, to perform containment and

cleanup. A boom was observed across McDowell Creek just upstream of the Neck Road
bridge to contain floatables. No sewer solids were observed in McDowell Creek. At the
time of the investigation, CMU advised that a valve had failed at the plant causing a loss
ofpump pressure resulting in the discharge of effluent from the manholes.
Mr. Rimer contacted Mr. Rozzelle and briefed him on the results of his investigation.
Mr. Rozzelle informed Mr. Rimer that tomorrow the two of them would collect water
samples in the creek, cove and lake to ascertain the extent of environmental damage. Mr.
Rozzelle asked Mr. Rimer to make the necessary arrangements with the lab and to secure
the necessary sample bottles, boat, etc.
January 19, 2003: Mr. Rozzelle and Mr. Rimer conducted a thorough evaluation of
surface waters downstream of the sewer discharge by performing water quality
monitoring activities at 20 sites in the creek, cove and lake, including immediately
adjacent to all drinking water intakes. The attached map shows the locations of these
monitoring sites and results. All 20 sites were sampled for fecal coliform bacteria. In
addition, field analyses for conductivity and dissolved oxygen were performed for the
lake sites. The field data indicated that dissolved oxygen levels in the cove and lake
were within acceptable levels and no negative impacts to aquatic life were observed.
Conductivity levels were elevated at sites 1, 2 and 3 (see attached map) with higher
levels recorded on the bottom of the lake. An inspection of the plant revealed that all
discharges had been discontinued and that sewer solids had been removed from the spill
area. There was also evidence that lime had been applied around the spill area for
disinfection.
January 20, 2003: Laboratory results were received indicating that elevated fecal
coliform bacteria levels were confined to McDowell Creek and McDowell Creek Cove.
January 21, 2003: Mr. Rimer and Mr. Buetow of MCWQP conducted water quality
monitoring activities on the creek, cove and lake to assess the continuing impacts from
the spill. Thirteen samples were collected in the lake and eight were collected in the
creek. Some of the monitoring sites differed from those on the previous Sunday in order
to better assess the spread of the contamination. Also, a smaller boat was used on
Tuesday which allowed sampling in the shallower areas of the cove. Field analyses were
also performed at all lake sites. A total of 8 samples were collected in the creek around
the spill area (see attached map).
January 21, 2003: CMU issued a press release stating that the spill was the result of
human error and not a mechanical problem as previously reported.
January 22, 2003: Lab results were received for the January 21 samples indicating that
the sewage had moved through McDowell Creek Cove and reached the main channel (see
attached map).
January 28, 2003: Mr. Rimer and Mr. Buetow collected fifteen samples in the lake and
eight samples in McDowell Creek around the spill area.

Plant spill caused by human error
HUNTERSVILLE — Saturday's sewer spill at the McDowell Creek Wastewater Treatment Plant
was the result of human error and not a mechanical problem as previously suspected.
Charlotte -Mecklenburg Utilities first believed the source was a pipe blockage caused by a broken
underground pipe valve. As repairs took place through the holiday weekend it was determined
the valve was not broken. Upon further investigation it has been determined that another valve
had been inadvertently closed Saturday to fix a broken water line.
That shut -down of a key valve caused a blockage and backup in the line that delivers wastewater
into the plant for treatment. An estimated 2.5 million gallons of wastewater spilled from manholes
outside the plant over several hours Saturday as Utilities staff worked to stop the overflow and
set up a temporary bypass pumping system before returning the plant to normal operation.
°Our account has turned out differently after interviewing plant employees and recreating the
actions that were taken during the day on Saturday," Utilities Director Doug Bean said Tuesday.
Some of Saturday's spillage was contained but most flowed into McDowell Creek. State and
local water quality agencies were quickly notified Saturday and will receive corrected information
today. The Mecklenburg Water Quality Program took water quality samples up and down the
creek and in Mountain Island Lake as a precaution on Sunday. The results show elevated fecal
coliform numbers in the McDowell Cove, but no fish kill or other significant environmental
impacts have been identified. The public drinking water supply remains safe.
Along with state and local water quality officials, Utilities staff notified other cities located along
Mountain Island Lake. Property owners along Neck Road and in close proximity to the spill were
notified.
McDowell Plant treats an average of 5 million gallons of wastewater per day and serves
northwestern Mecklenburg County. The plant has an excellent performance history. It has
recently earned national awards for protecting the environment through compliance with its
discharge permit.
"This spill was the result of operator errors," Bean said. °Our organization will learn from it and
we are very sorry it happened. But in spite of this event I want to re-emphasize that our
employees are hardworking and qualified professionals with a proven record of providing safe
drinking water and protecting our environment through day -in, day -out treatment of the
community's wastewater."

FINDINGS AND DECISION
AND ASSESSMENT OF
CIVIL PENALTIES
Acting pursuant to delegation provided by the Secretary of the Department of
Environment and Natural Resources and the Director of the Division of Water Quality, I, Coleen
H. Sullins, Deputy Director of the Division of Water Quality (DWQ), make the following:
FINDINGS OF FACT:
A. Charlotte -Mecklenburg Utilities (CMU) operates the 6.0 million gallon per day
McDowell Creek Wastewater Treatment Plant (WW TP) in Huntersville, North
Carolina, which is located in Mecklenburg County.
B. CMU was issued NPDES Permit No. NC0036277 for the treatment and discharge
of wastewater from the McDowell Creek WWTP on March 9, 2001, effective
April 1, 2001, with an expiration date of February 28, 2005.
C. On January 18, 2003, Mecklenburg County Water Quality Program (MCWQP)
staff observed a discharge of untreated wastewater from a sewer collection system
manhole at the McDowell Creek WWTP to McDowell Creek and Mountain
Island Lake. Mountain Island Lake are Class WS-IV waters of the State in the
Catawba River basin.
D. CMU had no valid permit for the above -described activity.
E. The water quality standard for fecal coliform bacteria within Class WS-IV waters
shall not exceed a geometric mean of 200 colonies per 100 ml (200/100m1), based
upon five consecutive samples examined during a 30 day period, nor exceed 400
colonies/100m1 in more than 20% of the samples examined during a such period
as set forth in 15A NCAC 2B.0211(3)(e).

F. From January 19, 2003 through January 28, 2003, MCWQP staff collected sixty-
nine (69) surface water samples from McDowell Creek and Mountain Island Lake.
Twenty-one (21) samples exceeded 400 colonies/100ml. This is 30%© of the
samples.
G. NPDES Permit No. NC 0036277 contains the following relevant condition:
Part II, Section C, 2: Proper Operation and Maintenance. The Permittee shall at

discharge at McDowell Creek WWTP.
On March 13, 2003, MRO received a written response dated March 6, 2003 from
CMU regarding the Notice of Violation. CMU's response stated that the
wastewater discharge was the result of an operator closing a valve on the force
main from the influent pump station. The response also stated that the "spill was
clearly the result of mistakes made in the operation of the plant."
The cost to the State of the enforcement procedures in this matter totaled $300.52.

AND
ASSESSMENT OF CIVIL PENALTIES
Acting pursuant to delegation provided by the Secretary of the Department of
Environment and Natural Resources and the Director of the Division of Water Quality, I, Jeff
Poupart, Supervisor for the Non -Discharge Compliance and Enforcement Unit of the Division of
Water Quality (DWQ), make the following:
FINDINGS OF FACT:
A. Charlotte -Mecklenburg Utilities is a utility organized and existing under the laws
of the State of North Carolina.
B. Charlotte -Mecklenburg Utilities operates the 6.0 MGD McDowell Creek
Wastewater Treatment Plant (WWTP) in Huntersville, North Carolina, which is
located in Mecklenburg County.
C. Charlotte -Mecklenburg Utilities was issued NPDES Permit No. NC0036277 for
the treatment and discharge of wastewater from the McDowell Creek WWTP on
March 9, 2001, effective April 1, 2001, with an expiration date of February 28,
2005.
D. Said permit contains the following relevant condition:

E. On January 18, 2003, Mecklenburg County Water Quality Program (MCWQP) staff
observed a discharge of untreated wastewater to McDowell Creek and Mountain
Island Lake (Class WS-IV Waters of the State) by Charlotte -Mecklenburg Utilities
from a sewer collection system manhole at the McDowell Creek P. The
inspection was made by MCWQP pursuant to a cooperative working agreement
between Mecklenburg County and the Division of Water Quality.
F. A Notice of Violation dated February 18, 2003, was issued to the Charlotte -
Mecklenburg Utilities by DWQ's Mooresville Regional Office (DWQ/MRO)
concerning the discharge of 2.5 MG of untreated wastewater in violation of G.S. 143-
215.1(a) and NPDES permit NC0036277.
G. On March 13, 2003 DWQ/MRO received a written response dated March 6, 2003
from Charlotte -Mecklenburg Utilities regarding the above Notice of Violation. The
response stated that the wastewater discharge was the result of an operator
inadvertently closing a valve on the force main from the influent pump station while
trying to stop a non -potable water leak at the facility. The response also stated that
the spill was clearly the result of mistakes made in the operation of the plant. (See
attached response letter.)
H. Charlotte -Mecklenburg Utilities had no valid permit for the above described activity.
L The cost to the State of the enforcement procedures in this matter totaled $300.52.
Based upon the above Findings of Fact, I make the following:
II. CONCLUSIONS OF LAW:
A. Charlotte -Mecklenburg Utilities is a "person" within the meaning of North
Carolina General Statute (G.S.) 143-212(4).

Mecklenburg County, NC
Registered Agent: City of Charlotte
Address:
Regional Office: Mooresville
The degree and extent of harm to the natural resources of the State, to the public
health, or to private property resulting from the violation:
No harm has been measured or quantified; however, discharges of untreated wastewater
can impact the waters of the State by causing violations of water quality standards and
criteria which are established to protect aquatic life and the designated uses of the
receiving stream (i.e., recreation, agriculture, water supply, etc.).
2. The duration and gravity of the violation:
The bypass lasted approximately 8.5 hours resulting in the release of 2.5 MG of raw
sewage to McDowell Creek and Mountain Island Lake, Class WS-IV water in the
Catawba River Basin. The discharge was the result of operator error. The operator
closed a valve on the force main from the influent pump station, which caused sewage to
backup and discharge from a sewer manhole. See attached response from CMU dated
March 6, 2003.
The effect on ground or surface water quantity or quality or on air quality:
Surface water samples were collected that contained fecal coliform levels in excess of
6000 col./100 ml. in Mountain Island Lake. See attached sample results and map. It is
unlikely that the violation would have an effect on either groundwater quality or quantity
or on air quality.

De
This is in response to your Febniary 18, 2003, Notice of Violation and Recommendation for
Enforcement relative to a January 18, 2003, incident at the subject wastewater treatment plant.
That unfortunate incident was the result of errors made in the plant operation. Upon discovery of
the spill, Charlotte Mecklenburg Utilities took immediate actions to stop the spill, contain the
spillage, clean up the impacted area, and notify adjacent residents. The McDowell Creek
WWTP is a very high -performing plant and takes great pride in its past performance. This
incident was the result of human errors that were unexpected and that have caused us much
dismay.
On Saturday, January 18, 2003, an above ground, 2" water main carrying treated effluent (non -
potable water or "NPW") that is used internally within the McDowell plant split. The operator
on duty operated valves and successfully stopped the water from gushing from the split at
approximately 10:00 a.m. This NPW is also used to operate hydraulic control valves on the
pumps in the influent pumping station. The operator noticed that although these pumps were
running, no wastewater was being pumped. The operator believed the reason the pumps were
not pumping was related to the reduced NPW water supply to the control valves since he had just
gotten the leak stopped in that system. The operator worked for a considerable time to try to
ensure that the control valves were in fact open, but was still unable to get any output from the
pumps. At approximately 4:00 p.m., the operator called the plant supervisor who immediately
traveled to the plant. Upon his arrival, the supervisor observed the then -flooded influent pump
station. He called a local pump rental company who quickly transported portable pumps and
temporary piping to the plant site and began setting it up to by-pass pump from the influent
pump station to the preliminary treatment works at the top of the plant. Utilities wastewater
collection crews had also responded to the spill and were working to set up filter fabric dams in
the stream to try to capture as much of the solids as they could. By this time, Utilities' Director,
Deputy Director, Wastewater Treatment Superintendent, Instrumentation and Controls
Supervisor, and additional operators, and mechanics were also on -site, along with several
Administrative Division 5100 Brookshire Blvd. Charlotte, NC 28216 Phone: [phone] Fax: [phone]
Charlotte -Mecklenburg Utilities

consulting engineers who are familiar with the plant. Mecklenburg County Water Quality
Program staff had also been contacted and arrived on site.
Utilities also notified our own water treatment plant and those of Gastonia and Mount Holly who
are the only other cities who withdraw drinking water from Mountain Island Lake. All of these
intakes are several miles downstream of the spill location. None of the water plants reported any
difficulties due to the spill.
At that time, it was not clear why the pumps were not moving wastewater. Utility technicians
were hard at work conducting pressure and equipment tests to diagnose the problem. Others
were studying record drawings of the plant, trying to find solutions. At the same time, the
operator on duty was undergoing rigorous de -briefing to re -trace his steps and actions from
earlier in the day. All of this effort led to the conclusion that the most likely cause of the
problem was the failure of a large gate valve on the 24" force main outside of the influent
pumping station. The decision was made to try to re -activate an old section of smaller force
main (abandoned during a previous expansion of the plant) to by-pass the suspected valve. That
work resulted in restoration of flow to the head of the plant and an end to the overflow at 9:30
p.m. There was still concern that the re -activated line may not be able to sustain peak influent
flows, so the temporary pumps and piping were left in place.
On Sunday, an on -site contractor, Utilities staff, and our consultants developed a repair plan and
mobilized / prepared to uncover the suspected valve (more than 10' deep, surrounded by other
piping, and in unstable soil) for repair on Monday. Also on Sunday, Utilities issued a news
release, gave several media interviews, and contacted two Mountain Island Lake Covekeepers by
telephone to inform them of the situation.
On Monday, the valve was uncovered and found to be in good shape and not the source of the
problem.
Continued diagnostics, investigation, and questioning of the operator on Monday finally revealed
that the operator had in fact closed a valve on the force main from the influent pump station
while trying to stop the NPW leak. Prior to this time, the operator had reported (repeatedly) that
he had not operated any valves in that area of the plant. It also turned out that this same valve
was actually re -opened on Saturday night as part of the effort to re -activate the abandoned force
main.
Utilities has taken appropriate actions relative to the operator's failure to notify supervisors
sooner that a problem existed and for not being forthcoming in reporting valves that he had
operated that day.
Utilities calculated the volume of wastewater spilled by comparing the hourly flow records from
the same time period one week earlier. According to data recorded at the plant, water levels in
the wet well reached the top (crown) of the 36" influent pipe into the plant at 1:00 p.m. From
that point, flow continued to back up in the pipe and manholes until it overflowed from manholes
upstream of the plant. The level recorder in the wet well does not operate when the water level is
above this point, so it is not possible to deteiniine exactly when the water level reached the

elevation of the lowest upstream manhole. At 9:30 p.m., after the flow through the force main
had been restored, the water level in the wet well had dropped to the crown of the pipe as the
backup subsided. Therefore, the spill was reported to have occurred and the volume spilled was
calculated based on the hours between 1:00 p.m. and 9:30 p.m. At 1:00 p.m. on Saturday,
January 18, the flow rate into the plant was almost exactly the same rate as that time on the
previous Saturday, thereby confirming that using the previous week flow data was appropriate.
In addition to the state -required public notifications of a spill of this magnitude, Utilities placed
door hanger spill notices with the closest residents. Because of the time of year, extreme cold
weather (temperatures that day were between 10° and 30° F), cold lake water temperatures, and
the resulting unlikelihood that anyone was in body contact with the lake water, Utilities did not
notify the nearest lake front properties, who were nearly a mile away from the spill area. In
hindsight, we should have notified those residents as well.
Utilities' response to spills is to take immediate actions and to call on any needed resources to
stop the spill and clean up the area. In this case, we brought in temporary pumping and piping
($28,404), tried to capture solids in the stream ($3,133), and used a contractor already on site to
uncover and inspect the suspected valve ($8,720). We also mobilized Utilities staff (recall that
this was a holiday weekend) ranging from additional operators to the Utilities Director and
consultants to help manage, diagnose, and resolve the problem.
Utilities crews also worked to remove debris and to clean up the areas impacted by the spill.
Mecklenburg County Water Quality Program staff collected samples from the stream and from
various locations in McDowell Cove and Mountain Island Lake. Samples were collected on
several days following the spill to determine how widespread the impacts were. County data
showed that the effects of the spill were fairly limited, with the greatest impacts in the stream and
in the rear of the McDowell Creek Cove of the lake. The impacts to the stream and the cove
were primarily elevated fecal colifoitu levels and within less than two weeks there was no
evidence of the spill. We are not aware of any fish killed by this incident.
To avoid similar problems in the future, Utilities is checking and confirming existing valve
markings / labeling and providing additional markings where needed for all critical valves on the
plant site. A large schematic of the plant piping and valves is being mounted on a wall within
the plant showing the valve labels so that an operator would not need to search out and interpret
plant construction drawings to identify valves (note that in this incident the operator did not
check plant drawings to try to determine which valve should be operated — this work is being
done as a precaution and to further aid staff in operating the plant). Plant operators have been
strongly reminded that they need to call for assistance immediately if they encounter unusual
operating problems. Utilities has also reviewed internal procedures for placing door hangers and
notifying residents on spills of this type. In addition to these immediate actions, Utilities has
plans to construct flow equalization facilities at this plant as part of an upcoming expansion
project. Similar facilities at other Utilities plants have been utilized to avoid spills when
problems have occurred at influent pumping stations or at other critical locations within the
plant.

We have attached an aerial photo of the plant area that is marked to show where the spill
occurred and which residents were notified via door hangers.
As detailed above, this spill was clearly the result of mistakes made in the operation of the plant.
When the operator reported the problem to others, Utilities' staff moved quickly and decisively,
brought in all needed resources, stopped the spill, cleaned up the area and performed
notifications. The spill was not due to the failure of any mechanical or electrical system nor to
the lack of existence of proper operating procedures. Even so, we are reviewing and reinforcing
procedures and systems that could help prevent similar future incidents. We are very sorry that
the incident occurred.
Please let me know if you have any questions.

McDowell Creek Wastewater Treatment Plant, 4901 Neck
Rd., Huntersville, N.C.
Discharge of an estimated 2.5 million gallons of untreated
wastewater to McDowell Creek
Charlotte Mecklenburg Utilities
January 18, 2003 at 6:59 p.m..; Mr. David Rimer of the Mecklenburg County Water
Quality Program (MCWQP) received a telephone call from Mr. Earle Peigler of Charlotte
Mecklenburg Utilities (CMU) advising that over one million gallons of untreated
wastewater had been released from the McDowell Creek Wastewater Treatment Plant
into McDowell Creek. The spill was reported as currently active.
January 18 at 7:04 p.m.: Mr. Rimer contacted Mr. Rusty Rozzelle, Water Quality
Program Manager, and advised him of the situation. Mr. Rozzelle informedRimer to
immediately conduct an onsite investigation of the spill to ascertain the environmental
impacts and obtain as much information as possible concerning the cause of the spill and
the actions being taken to eliminate the discharge. Mr. Rozzelle also asked Mr. Rimer to
advise CMU to issue a press release and notify the residents of McDowell Creek Cove as
well as the operators of the downstream drinking water intakes.
January 18 at 7:06 p.rn.: Mr. Rimer received a telephone call from Jackie Jarrell, head of
CMU's wastewater treatment facilities, asking for contact information on the water
intakes on Mountain Island Lake, where McDowell Creek discharges into. Mr. Rimer
provided this information. Mr. Rimer strongly advised Ms. Jarrell to issue a press release
and to notify those who lived near the spill as well as the operators of the water intakes.
January 18 at 8:00 p.rn.: Mr. Rimer met Earl Peigler of CMU at the McDowell Creek
Wastewater Treatment Plant. They walked to where the sewage overflows had occurred
and observed large quantities of sewer solids accumulated around two manholes
immediately upstream of the plant but no active overflow was observed. The sewer
discharge had entered McDowell Creek which, at the time of the investigation, was
slightly turbid and carrying a large volume of water, possibly due to runoff from the
recent snow storm. A mild sewer odor was detected around the creek. CMU had
contacted Hepaco, an environmental cleanup company, to perform containment and

cleanup. A boom was observed across McDowell Creek just upstream of the Neck Road
bridge to contain floatables. No sewer solids were observed in McDowell Creek. At the
time of the investigation, CMU advised that a valve had failed at the plant causing a loss
of pump pressure resulting in the discharge of effluent from the manholes.
Mr. Rimer contacted Mr. Rozzelle and briefed him on the results of his investigation.
Mr. Rozzelle informed Mr. Rimer that tomorrow the two of them would collect water
samples in the creek, cove and lake to ascertain the extent of environmental damage. Mr.
Rozzelle asked Mr. Rimer to make the necessary arrangements with the lab and to secure
the necessary sample bottles, boat, etc.
January 19, 2003: Mr. Rozzelle and Mr. Rimer conducted a thorough evaluation of
surface waters downstream of the sewer discharge by performing water quality
monitoring activities at 20 sites in the creek, cove and lake, including immediately
adjacent to all drinking water intakes. The attached map shows the locations of these
monitoring sites and results. All 20 sites were sampled for fecal coliform bacteria. In
addition, field analyses for conductivity and dissolved oxygen were performed for the
lake sites. The field data indicated that dissolved oxygen levels in the cove and lake
were within acceptable levels and no negative impacts to aquatic life were observed.
Conductivity levels were elevated at sites 1, 2 and 3 (see attached map) with higher
levels recorded on the bottom of the lake. An inspection of the plant revealed that all
discharges had been discontinued and that sewer solids had been removed from the spill
area. There was also evidence that lime had been applied around the spill area for
disinfection,
January 20, 2003: Laboratory results were received indicating that elevated fecal
colifoii !bacteria levels were confined to McDowell Creek and McDowell Creek Cove.
January 21, 2003: Mr. Rimer and Mr. Buetow of MCWQP conducted water quality
monitoring activities on the creek, cove and lake to assess the continuing impacts from
the spill. Thirteen samples were collected in the lake and eight were collected in the
creek. Some of the monitoring sites differed from those on the previous Sunday in order
to better assess the spread of the contamination. Also, a smaller boat was used on
Tuesday which allowed sampling in the shallower areas of the cove. Field analyses were
also pedali ied at all lake sites. A total of 8 samples were collected in the creek around
the spill area (see attached map).
January 21, 2003: CMU issued a press release stating that the spill was the result of
human error and not a mechanical problem as previously reported.
January 22, 2003: Lab results were received for the January 21 samples indicating that
the sewage had moved through McDowell Creek Cove and reached the main channel (see
attached map).
January 28, 2003: Mr. Rimer and Mr. Buetow collected fifteen samples in the lake and
eight samples in McDowell Creek around the spill area.

January 29, 2003: Lab results received. All fecal results were low and below MCWQP
action levels (see attached map).
February 10, 2003: State notice of violation and recommendation for enforcement was
mailed to the Mooresville Regional Office.

Plant spill caused by human error
HUNTERSVILLE — Saturday's sewer spill at the McDowell Creek Wastewater Treatment Plant
was the result of human error and not a mechanical problem as previously suspected.
Charlotte -Mecklenburg Utilities first believed the source was a pipe blockage caused by a broken
underground pipe valve. As repairs took place through the holiday weekend it was determined
the valve was not broken. Upon further investigation it has been determined that another valve
had been inadvertently closed Saturday to fix a broken water line.
That shut -down of a key valve caused a blockage and backup in the line that delivers wastewater
into the plant for treatment. An estimated 2.5 million gallons of wastewater spilled from manholes
outside the plant over several hours Saturday as Utilities staff worked to stop the overflow and
set up a temporary bypass pumping system before returning the plant to normal operation.
"Our account has turned out differently after interviewing plant employees and recreating the
actions that were taken during the day on Saturday," Utilities Director Doug Bean said Tuesday.
Some of Saturday's spillage was contained but most flowed into McDowell Creek. State and
local water quality agencies were quickly notified Saturday and will receive corrected information
today. The Mecklenburg Water Quality Program took water quality samples up and down the
creek and in Mountain Island Lake as a precaution on Sunday. The results show elevated fecal
coliform numbers in the McDowell Cove, but no fish kill or other significant environmental
impacts have been identified. The public drinking water supply remains safe.
Along with state and local water quality officials, Utilities staff notified other cities located along
Mountain Island Lake. Property owners along Neck Road and in close proximity to the spill were
notified.
McDowell Plant treats an average of 5 million gallons of wastewater per day and serves
northwestern Mecklenburg County. The plant has an excellent performance history. It has
recently earned national awards for protecting the environment through compliance with its
discharge permit.
"This spill was the result of operator errors," Bean said. "Our organization will learn from it and
we are very sorry it happened. But in spite of this event I want to re-emphasize that our
employees are hardworking and qualified professionals with a proven record of providing safe
drinking water and protecting our environment through day -in, day -out treatment of the
community's wastewater."

SERVICE REQUESTED..:
Earle Paigler of CMU reports that over 1 million gallons of raw sewage had been released into the environment from the
McDowell Creek WWTP
ACTION TAKEN......,:
Saturday 1-18-03 6:59 pm David Rimer received telephone call from Earle Paigler of CMU advising MCWQP that McDowell
Creek WWTP had spilled over one million gallons of raw sewage into McDowell Creek. The spill is active and CMU does not
yet have everything under control.
7:04 pm David Rimer called Rusty Rozzelle, WQ Program Manager, and advised him of the spill.
7:06 pm David Rimer received telephone call from Jackie Jarrell, head of CMU's wastewater treatment facilities, asking for
contact information on the water intakes on Mountain Island Lake, where McDowell Creek discharges into. Provided
requested information to Mrs. Jarrell.
8 pm David Rimer met Earl Paigler at the McDowell Creek WWTP. We walked to where the sewage overflows had
occurred. Observed two manholes in the sanitary main where there were large amounts of sewer solids surrounding the
manholes with no active overflow, The overflow had entered an unnamed tributary to McDowell Creek which, at the time of
my observation, was flowing clear with a large volume possibly due to runoff from the recent ice snow storm. McDowell Creek
was moderately turbid in appearance with a mild smell of raw sewage in the air.
CMU earlier had called out Hepaco to perform containment and cleanup. A boom was already across McDowell Creek just
upstream of the Neck Road bridge to catch any floatables. Observed no solids in McDowell Creek.
The latest word from CMU was that a valve had failed and the plant had lost pressure and influent causing the overflows.
Briefed Rusty Rozzelle on my findings. We will be taking water samples in Mountain Island Lake tomorrow as well as
samples in McDowell Creek. Strongly advised CMU to make a press release and to notify those who lived near the spill.
Arranged with the Charlotte Mecklenburg Police Department to use their boat for the lake run.
1-19-03 David Rimer and Rusty Rozzelle took fifteen samples in Mountain Island Lake from inside McDowell Creek Cove to
CMU's Water Intake to Gastonia's & Mt. Holly Intake near MI dam. Took five samples in McDowell Creek around the spill
location.
1-20-03 Lab results showed that high fecal levels was inside McDowell Cove but not near any housing.
1-21-03 David Rimer and Dave Buetow conducted a special MI lake run. Collected fifteen samples in MI Lake. Also
collected eight samples in McDowell Creek around the spill.

2003 SERVICE REQUEST/WORK ORDER
1-21-03 CMU issued a press release stating that the spill was he result of human error and not a mechanical problem as
previously suspected.
Received lab results for 1-20-03 samples. The results indicate that the sewage had moved through McDowell Creek Cove
and reached the main channel.
1-22-03 Mecklenburg County government is closed due to inclement weather. No lake rum was conducted.
1-23-03 Due to sub -zero temperatures and ice on the boat ramps, no lake run was conducted.
1-28-03 David Rimer and Dave Buetow conducted a special MI lake run collecting fifteen samples in MI Lake. Also collected
eight samples in McDowell Creek Cove around the spill.
1-29-03 Received lab results. All fecal results are low and below action levels. The attached map provides sampling
locations and results.
1-30-03 Completed draft of state NOV/NRE and gave hard copy to Dave Caldwell for review.
2-6-03 Completed second draft of state NOV/NRE and gave hard copy to Dave Caldwell for review.
2-10-03 Completed third draft of state NOV/NRE and gave hard copy to Dave Caldwell for review.
Mailed hard copy and floppy disk copy of state NOV/NRE to Richard Bridgeman of MRO.
2-18-03 MRO issued NOV/NRE to CMU for the 1-18-03 incident at McDowell Creek WWTP.
3-13-03 Received written response to MRO from CMU dated March 6, 2003. Mr. Barry Bullet, CMU Deputy Director, wrote
that CMU was taking action to avoid similar problems in the future: 1) CMU is checking and confirming existing valve
markings/labeling and providing additional markings where needed for all critical valves on the plant site. 2) A large
schematic of the plant piping and valves is being mounted on a wall within the plant showing the valve labels so that an
operator would not need to search out and interpret plant construction drawings to identify valves. 3) Plant operators have
been strongly reminded that they need to call for assistance immediately if they encounter unusual operating problems. 4)
CMU has plans to construct flow equalization facilities at this plant as part of an upcoming expansion project. Similar facilities
at other Utilities plants have been utilized to avoid spills when problems have occurred at influent pumping stations or at other
critical locations with the plant.
3-28-03 Dave Caldwell, WQ Supervisor, received a telephone call from Dee Browder of the state DWQ office in Raleigh. Ms.
Browder stated that the state will be pursuing a penalty against CMU as a result of the spill.
3-31-03 Spoke with Dave Caldwell regarding the penalty action. The state will provide MCWQP guidance on the format and
wording of the penalty action today. The penalty action will be documented in a separate EPIC service request.
This service request is considered complete.

NVIRooworm,
REcw* At
This is in response to your February 18, 2003, Notice of Violation and Recommendation for
Enforcement relative to a January 18, 2003, incident at the subject wastewater treatment plant.
That unfortunate incident was the result of errors made in the plant operation. Upon discovery of
the spill, Charlotte Mecklenburg Utilities took immediate actions to stop the spill, contain the
spillage, clean up the impacted area, and notify adjacent residents. The McDowell. Creek
WWTP is a very high -performing plant and takes great pride in its past performance. This
incident was the result of human errors that were unexpected and that have caused us much
dismay.
On Saturday, January 18, 2003, an above ground, 2" water main carrying treated effluent (non -
potable water or "NPW") that is used internally within the McDowell plant split. The operator
on duty operated valves and successfully stopped the water from gushing from the split at
approximately 10:00 a.m. This NPW is also used to operate hydraulic control valves on the
pumps in the influent pumping station. The operator noticed that although these pumps were
running, no wastewater was being pumped. The operator believed the reason the pumps were
not pumping was related to the reduced NPW water supply to the control valves since he had jtts
gotten the leak stopped in that system. The operator worked for a considerable time to try to
ensure that the control valves were in fact open, but was still unable to get any output from the
pumps. At approximately 4:00 p.m., the operator called the plant supervisor who immediately
traveled to the plant. Upon his arrival, the supervisor observed the then -flooded influent pump
station. He called a local pump rental company who quickly transported portable pumps and
temporary piping to the plant site and began setting it up to by-pass pump from the influent
pump station to the preliminary treatment works at the top of the plant. Utilities wastewater
collection crews had also responded to the spill and were working to set up filter fabric darns in
the stream to try to capture as much of the solids as they could, By this time, Utilities' Director,
Deputy Director, Wastewater Treatment Superintendent, instrumentation and Controls
Supervisor, and additional operators, and mechanics were also on -site, along with several.

consulting engineers who are familiar with the plant. Mecklenburg County Water Quality
Program staff had also been contacted and arrived on site.
Utilities also notified our own water treatment plant and those of Gastonia and Mount Holly who
are the only other cities who withdraw drinking water from Mountain Island Lake. All of these
intakes are several miles downstream of the spill location. None of the water plants reported any
difficulties due to the spill.
At that time, it was not clear why the pumps were not moving wastewater. Utility technicians
were hard at work conducting pressure and equipment tests to diagnose the problem. Others
were studying record drawings of the plant, trying to find solutions. At the same time, the
operator on duty was undergoing rigorous de -briefing to re -trace his steps and actions from
earlier in the day. All of this effort led to the conclusion that the most likely cause of the
problem was the failure of a large gate valve on the 24" force main outside of the influent
pumping station. The decision was made to try to re -activate an old section of smaller force
main (abandoned during a previous expansion of the plant) to by-pass the suspected valve. That
work resulted in restoration of flow to the head of the plant and an end to the overflow at 9:30
p.m. There was still concern that the re -activated line may not be able to sustain peak influent
flows, so the temporary pumps and piping were left in place.
On Sunday, an on -site contractor, Utilities staff, and our consultants developed a repair plan and
mobilized / prepared to uncover the suspected valve (more than 10' deep, surrounded by other
piping, and in unstable soil) for repair on Monday. Also on Sunday, Utilities issued a news
release, gave several media interviews, and contacted two Mountain Island Lake Covekeepers by
telephone to inform them of the situation.
On Monday, the valve was uncovered and found to be in good shape and not the source of the
problem.
Continued diagnostics, investigation, and questioning of the operator on Monday finally revealed
that the operator had in fact closed a valve on the force main from the influent pump station
while trying to stop the NPW leak. Prior to this time, the operator had reported (repeatedly) that
he had not operated any valves in that area of the plant. It also turned out that this same valve
was actually re -opened on Saturday night as part of the effort to re -activate the abandoned force
main.
Utilities has taken appropriate actions relative to the operator's failure to notify supervisors
sooner that a problem existed and for not being forthcoming in reporting valves that he had
operated that day.
Utilities calculated the volume of wastewater spilled by comparing the hourly flow records from
the same time period one week earlier. According to data recorded at the plant, water levels in
the wet well reached the top (crown) of the 36" influent pipe into the plant at 1:00 p.m. From
that point, flow continued to back up in the pipe and manholes until it overflowed from manholes
upstream of the plant. The level recorder in the wet well does not operate when the water level is
above this point, so it is not possible to determine exactly when the water level reached the

elevation of the lowest upstream manhole. At 9:30 p.m., after the flow through the force main
had been restored, the water level in the wet well had dropped to the crown of the pipe as the
backup subsided. Therefore, the spill was reported to have occurred and the volume spilled was
calculated based on the hours between 1:00 p.m. and 9:30 p.m. At 1:00 p.m. on Saturday,
January 18, the flow rate into the plant was almost exactly the same rate as that time on the
previous Saturday, thereby confirming that using the previous week flow data was appropriate.
In addition to the state -required public notifications of a spill of this magnitude, Utilities placed
door hanger spill notices with the closest residents. Because of the time of year, extreme cold
weather (temperatures that day were between 10° and 30° F), cold lake water temperatures, and
the resulting unlikelihood that anyone was in body contact with the lake water, Utilities did not
notify the nearest lake front properties, who were nearly a mile away from the spill area. In
hindsight, we should have notified those residents as well.
Utilities' response to spills is to take immediate actions and to call on any needed resources to
stop the spill and clean up the area. In this case, we brought in temporary pumping and piping
($28,404), tried to capture solids in the stream ($3,133), and used a contractor already on site to
uncover and inspect the suspected valve ($8,720). We also mobilized Utilities staff (recall that
this was a holiday weekend) ranging from additional operators to the Utilities Director and
consultants to help manage, diagnose, and resolve the problem.
Utilities crews also worked to remove debris and to clean up the areas impacted by the spill.
Mecklenburg County Water Quality Program staff collected samples from the stream and from
various locations in McDowell Cove and Mountain Island Lake. Samples were collected on
several days following the spill to determine how widespread the impacts were. County data
showed that the effects of the spill were fairly limited, with the greatest impacts in the stream and
in the rear of the McDowell Creek Cove of the lake. The impacts to the stream and the cove
were primarily elevated fecal coliform levels and within less than two weeks there was no
evidence of the spill. We are not aware of any fish killed by this incident.
To avoid similar problems in the future, Utilities is checking and confirming existing valve
markings / labeling and providing additional markings where needed for all critical valves on the
plant site. A large schematic of the plant piping and valves is being mounted on a wall within
the plant showing the valve labels so that an operator would not need to search out and interpret
plant construction drawings to identify valves (note that in this incident the operator did not
check plant drawings to try to determine which valve should be operated — this work is being
done as a precaution and to further aid staff in operating the plant). Plant operators have been.
strongly reminded that they need to call for assistance immediately if they encounter unusual
operating problems. Utilities has also reviewed internal procedures for placing door hangers and.
notifying residents on spills of this type. In addition to these immediate actions, Utilities has
plans to construct flow equalization facilities at this plant as part of an upcoming expansion
project. Similar facilities at other Utilities plants have been utilized to avoid spills when
problems have occurred at influent pumping stations or at other critical locations within the
plant.

We have attached an aerial photo of the plant area that is marked to show where the spill
occurred and which residents were notified via door hangers.
As detailed above, this spill was clearly the result of mistakes made in the operation of the plant.
When the operator reported the problem to others, Utilities' staff moved quickly and decisively,
brought in all needed resources, stopped the spill, cleaned up the area and performed
notifications. The spill was not due to the failure of any mechanical or electrical system nor to
the lack of existence of proper operating procedures. Even so, we are reviewing and reinforcing
procedures and systems that could help prevent similar future incidents. We are very sorry that
the incident occurred.
Please let me know if you have any questions.

Dear Mr. Gullet:

Subject: Speculative Discharge Limits
CMU McDowell Creek WWTP
This letter is in response to your request for speculative limits for an expansion of discharge flow from the McDowell
Creek Wastewater Treatment Plant, from the current permitted flow of 6.0 MGD to phased expansions of 6.6, 9, 12,
and 15 MGD. We have reviewed the request as well as modeling efforts conducted by the City/Consultant, and
provide the following comments.
The speculative limits presented here are based on our understanding of the proposal and of present environmental
conditions, The Division of Water Quality (DWQ) cannot guarantee that it will issue the City an NPDES permit to
discharge additional treated wastewater into waters of the State. Nor can we guarantee that the effluent limitations and.
other requirements included in any permit will be exactly as presented here. Final decisions on these matters will be
made only after the Division receives and evaluates a formal permit application for the City's proposed discharge.
Environmental Assessments of New Projects
Please be aware that you will have to evaluate this project for environmental impacts before receiving a modified
permit. Anyone proposing to construct new or expanded waste treatment facilities using public funds or public (state)
lands must first prepare an environmental assessment (EA) when wastewater flows (1) equal or exceed 0.5 MGD or
(2) exceed one-third of the 7Q10 flow of the receiving stream. DWQ will not accept a permit application for a project
requiring an environmental assessment until the Division has approved the EA and sent a Finding of No Significant
Impact (FONSI) to the state Clearinghouse for review and comment.
An Environmental Assessment should contain a clear justification for the proposed project. It should provide an
analysis of potential alternatives, including a thorough evaluation of non -discharge alternatives. Nondischarge
alternatives or alternatives to expansion, such as spray irrigation, water conservation, or inflow and infiltration
reduction, are considered to be environmentally preferable to a surface water discharge. In accordance with the North
Carolina General Statutes, the preferred alternative must be the practicable waste treatment and disposal alternative
with the least adverse impact on the environment. If the EA demonstrates that the project may result in a significant
adverse effect on the quality of the environment, you must then prepare an Environmental Impact Statement, Alex
Marks of the Water Quality Planning Branch can provide you further information regarding the requirements of the
N.C. Environmental Policy Act. You can contact Mr, Marks directly at [phone], ext. 555.
Total Nitrogen and Total Phosphorus
The facility currently has limits for total nitrogen (10 mg/I) and total phosphorus (1 mg/1) at 6 MGD. Using the
Bathtub model of Mountain Island Lake and McDowell Creek Cove developed by Black & Veatch for Charlotte
Mecklenburg Utilities, DWQ ran scenarios for phased expansion limits of total nitrogen and total phosphorus. The
modeling endpoint was to have 10% or less of the predictions exceed the chlorophyll -a water quality standard of 40
ug/L. Since there is some question about the effect of the Huntersville Ordinance on nonpoint source loading,
particularly in the near term, DWQ used the model results that included some increase in nonpoint source loading.

Speculative Letter
Attachment 1 provides the speculative limits for the phased expansions. At 9 MGD, substantial reductions in nutrient
load will be required. Specifically, DWQ recommends nutrient loading of 450 lbsJday total nitrogen and 22 lbsJday
total phosphorus. At 12 MGD, due to the increased flow, the model predicts that an increase in the total phosphorus
Toad to 27 Ibs/day is permissible. At 15 MGD, the Division wishes to reserve issuance of speculative limits, since the
impact of nonpoint source loading is both greater and more uncertain. Current model results for 15 MGD indicate a
nutrient load of 450 lbs./day total nitrogen and approximately 31 to 35 lbsJday total phosphorus, depending on the
level of nonpoint source loading, in order to meet the chlorophyll -a endpoint. DWQ recommends continuation of the
water quality monitoring in Mountain Island Lake and McDowell Creek Cove, as well as monitoring of the nutrient
loading from the McDowell Creek watershed. These data would improve predictions from the Bathtub model for
speculative limits at 15 MGD, closer to the time when that expansion would be necessary.
Other Parameters
Speculative limits for BOD (CBOD) and ammonia are based on best available technology. Speculative limits for TSS
and fecal coliform bacteria are based on Charlotte Mecklenburg Utilities projections of future treatment capability.
Additional parameters will be evaluated after receipt of the permit modification request.
If you have questions about the speculative limits, please contact Chris Roessler at [phone], ext. 506, or Tom
Belnick at [phone], ext. 543.

measurements. Sludge wasting is based on MLSS measurements. Screen iogs and grit are removed and
properly disposed by Republic Waste Services, Inc. The backup generators appeared to be well maintained.
A large amount of foam was observed on top of an anaerobic digester's cover (floating type). The ORC and
staff were utilizing a defoaming agent to reduce the accumulation of foam. The ORC and staff indicated
that the anaerobic digestion process would stabilize once the approved upgrades were completed. The ORC
and staff utilize an on-line computer system for monitoring of process equipment and tracking of WWTP
performance.
The facility compl
minimum requirements for staffing; however;- this office recommends the
incorporation of two certified operators per shift (during the weekends) due to the complexities of the
treatment process and for safety assurances. The ORC and staff were very knowledgeable of all treatment
process and equipment utilized at this facility.

Review Comments
April 23, 2002
General
Based on the A/E's certification in the Permit Application that all 15A NCAC 2H .0200
requirements regarding gravity sewers and force mains, and the Division of Water
Quality's Gravity Sewer Minimum Design Criteria adopted February 12, 1996 have been
met, a review of these items has not been performed. It shall be the permittee's
responsibility to ensure the plans and specifications meet the appropriate design criteria
and rules. Final approval of these documents will not imply approval of any variance
from these criteria unless specifically requested and granted. Failure to comply may
result in penalties in accordance with North Carolina General Statute 143-215.6A — 143-
215.6C, construction of additional facilities, and/or referral of the N.C. Professional
Engineer to the licensing board.
2. The Permit Application lists 20 lots. The Node Schematic in the Engineering Report lists
21 lots for Nodes El to E (Yachtman Dr.). Please clarify.
The flow values used in the hydraulic calculations are approximately 1/3 to 1/2 of that
derived by other accepted methods of pressure sewer design. Please provide references
and other appropriate documentation for this method (Q=15 + .5(No. Residences)).
4. The design appears to be concerned with a scenario where all pumps try to operate
simultaneously. This is not a requirement of DWQ. It is recognized that after a power
outage more that the average number of pumps may try to operate simultaneously.
However it is expected that under this condition some pumps would be able to operate
and others would not. As the operating pumps shut off, the other pumps would begin
operating as the TDH of the system drops sufficiently to allow them to come on. This
should happen within a time frame allowed by the available emergency storage in the
wetwell.
5. Provide the pressure at the tie in to the existing system.
6. Engineering Report, Page 11 - Based on data provided by E-One and other sources, it is
expected that on the average 5 pumps would be operating simultaneously. If the yield is
15.5 gpm per pump as noted on Plan Sheet 3, the flow would be 77.5 gpm and not the 25
gpm as noted here. (See Comment # 2 above).

7. Engineering Report, Page 12 — Maximum EGL — This indicates that all pumps are
operating simultaneously with a flow of 25 gpm. Confirm that this is the total yield from
20 pumps. If so, the pumps would yield 1.25 gpm per pump and it is likely that they are
operating at very near shutoff (assume centrifugal). If semi -positive displacement pumps
are used then the flow would be near 220 gpm (assumes E-One at 11 gpm at TDH of up to
138 ft.). A detailed model must be provided which shows the recommended pump per lot
to insure that the worst case lots will operate under the conditions present on this project.
This analysis should include the static head, the pressure at the tie in to the existing
system, headloss along the force main, headloss in the residential service piping as well
as minor loses due to valves, bends, etc.
8. Engineering Report, Page 16 — Downstream Capacity —
a. This indicates that a variance has been granted for a velocity less than 2 fps.
While certain lines may be designated as High Priority lines due to low velocities,
it is recommended that this be done only for lines that are designed to carry
additional flow in the future. Terminal lines which will not see increased flow in
the future should be designed as close to 2 fps as possible to minimize
maintenance requirements. It is understood that even these lines will experience
velocities less than 2 fps on occasion, depending on which particular pumps are
operating simultaneously.
b. Provide detailed calculations to show that the pumps on the existing system will
not be adversely affected by the addition of these 20 pumps to the system.
9. Engineering Report, Page 17 — Buoyancy Calculations - Provide complete buoyancy
calculations for the pump stations. The information provided is for E-One pump stations
only. Provide calculations for other wetwells that may be used on the project. The
calculations must be based on full submergence with a safety factor of approximately 1.5.
The calculations provided by E-One do not appear to meet this criteria (Appendix S).
Specifications
l . Specification Page XVIII-6 — The leakage formula does not contain the diameter as noted
in the text. The duration of the leakage test is to be two (2) hours with a maximum
leakage of 10 gpdim. In the area of wells there shall be no visible leakage.
2. The electrical panel must contain both an audible and visual alarm and be labeled with
the name and phone number of the emergency service provider regardless of whether the
panel is located inside or outside the residence.
Plans
Sheet 3 — An air release valve should be installed at Station 2+90. DWQ Minimum
Design Criteria for Pump Stations and Force Mains requires an air release valve at
elevation changes greater than 10 feet.
2. Sheet 3 — The table of pump selection data indicates that each pump will produce a flow
of 15.5 gpm at. TDH's ranging from 19 to 85 feet. Except for a couple of semi -positive
displacement pumps, this is not a reasonable assumption.

Review Comments
April 17, 2002
General
The revised documents (specifications, calculations, etc.) should be submitted as separate
bound documents, each with the A/E's seal and signature. While the bound document
previously submitted is signed and sealed, the integrity of the seal is lost when the
documents are separated for return to the applicant and for filing by this office.
2. Based on the A/E's certification in the Permit Application that all 15A NCAC 2H .0200
requirements regarding gravity sewers and force mains, and the Division of Water
Quality's Gravity Sewer Minimum Design Criteria adopted February 12, 1996 have been
met, a review of these items has not been performed. It shall be the permittee's
responsibility to ensure the plans and specifications meet the appropriate design criteria
and rules. Final approval of these documents will not imply approval of any variance
from these criteria unless specifically requested and granted. Failure to comply may
result in penalties in accordance with North Carolina General Statute 143-215.6A — 143-
215.6C, construction of additional facilities, and/or referral of the N.C. Professional
Engineer to the licensing board.
Attachment A indicates that the downstream sewer capability can be found in the
calculations for WQ0018154 for the 4" and 2"LPSS for Bethel Church Road. A copy of
those calculations must be included with this application. Those calculations must show
the effect of the new pumps on the operating conditions of the existing pumps.
4. The model utilized by the A/E ("Variable Grade Effluent Sewer Design Program V 2.2"
from the National Small Flows Clearing House, WVU) may be adequate for the overall
sizing of a LPSS, but it fails to address the actual operating conditions for specific pumps
at a given location. A requirement of this office is that specific pumps (or equal) must be
identified for each lot. The method used does not provide an accurate representation of
the requirements for each lot. See General Comments 5 — 8 below for more specific
concerns.
The design is based on a flow contribution of .87 gpm per dwelling unit for the entire
service area of 182 dwelling units. Models run by this office based on the profile data
and pump selection provided by the A/E yields a flow at the connection to the existing
system of 107 gpm to 118 gpm for the 40 units proposed in this project. This produces a
flow contribution of 2.68 to 2.95 gpm per dwelling unit. In addition, the tables on the
plans list the yield per house at 40 gpm. This would equate to only 1 pump operating at a
time. Based on Attachment 5, it is expected that 6 units would operate simultaneously.
This would produce a combined flow of 240 gpm rather that the 34.8 gpm generated from
the A/E's model (0.87 * 40). Please clarify.

6. The pump data by lot shown on the plans show a constant flow per unit of 40 gpm with
all TDH's less than 53 ft. The TDH's were apparently pulled from the hydraulic grade
line computed from the per unit flows noted in comment 3 above. Model runs by this
office produce a range of yields of 13.7 gpm at 97.4 ft. TDH to 26 gpm at 81.43 ft. TDH.
It is recommended that the project flows be reviewed and revised as necessary. Note that
these flows were based on pressure in the existing force main calculated from the same
0.87 gpm flows noted above. Therefore the flow values derived by the model used in this
office are only as accurate as the residual pressure estimation allows. It is recommended
that the residual pressure be confirmed by field measurements.
7. The flows generated at the extreme ends of the lines results in velocities less than 2 fps.
Unless the lines may be extended in the future, that the line sizes should be revised to
produce velocities at least 2 fps.
8. Calculations, Attachment 3, Page 1 of 2 — The total flow for the 35 units in the zone is
given as 41 gpm. This does not agree with the 0.87 gpm per unit design flow.
9. Attachment 4 is not legible. Provide a more readable copy if possible.
10. Reliability requirements — Provide a sketch showing the pump operating levels and alarm
levels to support the 4 ft available storage shown in Attachment 7. This storage is to be
above the high water alarm.
Specifications
1. The details submitted as Appendix B must clearly indicate that a screened vent is
required on all pump stations. Appendix B should be resubmitted as separate signed and
sealed specifications. Part A may be deleted as it is instructions to the A/E and not
construction specifications. See General Comment 1.
Plans
Sheet 2 - 4 - Show the pump model no. and impeller size used to determine the head and
flow in the pump information table.
2. Sheet 3
a. The force main within the 100 ft. radius of the wells must be encased in DIP and
all service lines routed outside this area per the variance granted April 13, 2000.
Since a water line is present, this may be disregarded if the wells are abandoned in
accordance with 15A NCAC 02C .0113 by a certified well contractor per 15A
NCAC 27.
b. Provide specific instructions to the contractor to keep at least 25 ft away from the
well at lot 20404. See Plan Comment 2.a.

I have received the above referenced Notice of Deficiency (NOD) for the Compliance Evaluation
Inspection report of the inspection conducted at McDowell Creek WWTP on February 26, 2002 by Wes
Bell of your office. The NOD requires a response for the Self Monitoring Deficiency found by Mr. Bell.
No other deficiencies were noted in the report.
The self -monitoring deficiency was for not sampling the effluent pH, temperature, dissolved oxygen and
conductivity on January 22, 2001. These samples were collected, however, the sample results were
not reported in the DMR. The missing sample results were not caught during the Direct Monitoring
Report (DMR) review that was conducted internally. Upon receiving the NOD, the McAlpine Lab (the
internal lab that is used by Charlotte -Mecklenburg Utilities) was contacted and the results were
obtained. Please find enclosed a copy of the revised page of the January 2001 DMR. This revised
copy includes the missed analytical report. The original revised page has been sent to Central Files.
If you have any questions about this response, or if you need further explanation, please give me a call
at 704/357-1344 or you may call the plant ORC, E.E. Gains, at 704/845-6443. Thank you for your

The facility was last inspected by Wes Bell of this office on December 7, 2000.
PERMIT:
The permit authorizes the continued operation of an existing 6.0 MGD wastewater treatment
facility consisting of mechanical bar screens, grit removal, primary clarifiers, biological nutrient
removal (BNR) system, tertiary filtration, final clarifiers, anaerobic sludge digestion, sand drying
beds, and UV disinfection.
The permit for this facility became effective on 4/1/01 and expires on 2/28/05. The review
of the self -monitoring data includes the requirements of the previously issued pemiit and associated
permit modifications.
RECORDS AND REPORTS:
Records and reports consisting of monthly monitoring reports (DMR's), chain of custody
forms, sample analysis reports, calibration data, flow charts, process control data, Operator -in -
Responsible Charge (ORC) sign -in log, and daily operation and maintenance logs are maintained in
accordance with permit requirements. An on-line computer system is also utilized to store laboratory
results and process control data. The facility's records were in-depth and well organized.
FACILITY SITE REVIEW:
The influent initially passes through a mechanical bar screen and the flow is measured before
being pumped via influent pump station to a fine mechanical bar screen and two aerated grit
chambers with air-lift grit removal. The screening and grit removal is followed by three primary
clarifiers (with lime additions) and two trickling filters (not in -use). The flow is split to two trains
that consist of a four celled anaerobic basin (two cells are in -use) with acetic acid or a cola syrup
additions, (2) two celled anoxic basins, two oxic basins, and two circular aeration basins. One of
the aeration basins in the second train is used to store waste sludge prior to digestion. The flow is
combined (from each train) and enters two secondary clarifiers, four denitrification effluent filters
with a wet well and mud well, UV disinfection, and cascade reaeration. There are four anaerobic
digesters (two floating cover and two being upgraded), 30 usable sand drying beds (34 total), and
a temporary sludge dewatering facility (belt filter press). The facility is also equipped to provide
alum additions and two back-up generators are available for stand-by power.
The Division issued an Authorization to Construct (ATC) on October 13, 2000 for the
addition of solids handling equipment/facilities and process improvements. The facility is currently
under construction for the approved new facilities and improvements.
OPERATION & MAINTENANCE:
All treatment units appeared to be operating properly and the surrounding grounds were well
maintained. The mixed liquor appeared well mixed and adequately oxygenated. The effluent from
the secondary clarifiers was clear with no floatable solids. The back-up generators are well
maintained. The ORC and staff were very knowledgeable of the treatment processes and equipment
used at the facility. In addition, an on-line computer system is used for monitoring of process
equipment and tracking of WWTP performance.

McDowell Creek WWTP
Page Three
OPERATION & MAINTENANCE cont'd:
A comprehensive process control program consists of DO, pH, ammonia, nitrates,
phosphorus, settleable solids, MLVSS, MLSS, microscopic examinations, and sludge blanket
measurements. The facility is in the process of renovating the AlkaPro System to continuously
monitor the pH levels for appropriate lime additions. Sludge wasting is based on MLSS
measurements. The facility had a comprehensive routine and preventative maintenance program.
The facility is staffed with a Grade IV ORC. Designated certified back-up operators are
available when the ORC is unable to visit the facility. The WWTP is adequately staffed with
certified operators 24 hours a day, 7 days per week.
LABORATORY:
The McAlpine Creek WWTP Laboratory (Certification #148) and the contracted services of
Pace Analytical Services (Certification #12) in Huntersville, N.C. and Simalabs International
(Certification #85) in Burlington, N.C. provide analytical support. The laboratories were not
evaluated during this inspection; however, the McAlpine Creek WJTP Laboratory was inspected
on 10/23/01, by Mr. Chet Whiting with the Division's Laboratory Certification Unit. The McAlpine
Creek WWTP Laboratory personnel perform the required analyses for the on -site parameters of pH,
temperature, and dissolved oxygen. The pH and DO meters and thermometer appeared to be
properly calibrated.
EFFLUENT/RECEIVING WATERS:
The facility discharges into McDowell Creek, which is a WS-IV water in the Catawba River
Basin. At the time of the inspection, the effluent was clear with no floatable solids or foam. The
receiving stream did not appear to be negatively impacted. The discharge outfall was accessible at
the time of the inspection.
SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period December 2000 through November
2001, inclusive. No limit violations were reported. No effluent temperature, pH, dissolved oxygen,
and conductivity were reported on January 22, 2001.
Composite samples are collected flow proportionately. All samples appeared to be properly
preserved and meet the required holding times.
FLOW MEASUREMENT:
Influent flow is measured continuously by an ultrasonic flow meter and parshall flume with
totalizer and chart recording. The flow meter is calibrated annually by CMU's Instrumentation and
Control Division. The flow meter was last calibrated on 2/25/02.
SLUDGE DISPOSAL:
The digested sludge is dewatered by a temporary on -site filter belt press operated by Bio-
nomic Services, in Charlotte, N.C. The dewatered sludge is ultimately land applied by Synagro
under the authority of Land Application Permit No. WQ0000057.

McDowell Creek WWTP

SLUDGE DISP©SAL cont'd:
The land application permit became effective 12/22/00 and expires 11/30/05. Please refer to
Ms. Ellen Huffman's (of this Office) land application inspection report dated 8/27/01 for the
inspection performed on 8/14/01.
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.

Secondary dilution capabilities will be provided. Three points of application for polymer
will be provided for each belt filter press.
The polymer feed system will include an emulsion polymer feed pump, wetting unit,
mixer, solution aging tanks, progressive cavity -type solution metering pumps, secondary
dilution capabilities, and control panel.
The polymer feed system will have start/stop control and feed rate control from the
control panel. The feed rate will be able to be automatically paced in proportion to the
sludge flow rate and the total suspended solids analyzer input to the BFPs, and it will
have a "manual dosage adjustment" from the control panel.
Dewatered Sludge Conveyor. A single sludge conveyor will be provided to convey
dewatered sludge from the BFPs to the biosolids storage area. The design will include
provisions to load trucks at a truck loading station between the dewatering building and
the biosolids storage area. The portion of the conveyor between the dewatering building
and the biosolids storage area will be covered and have an access walkway.
The belt conveyor will be provided with local manual, remote manual, and remote
automatic control. Remote automatic control will permit the operator to interlock the
conveyor with the biosolids dewatering system.
Filtrate Equalization Basin Pumping Station
A triplex pumping station will be installed near the new biosolids storage facility to pump
filtrate from two belt filter presses, storm water and washdown flows from the biosolids
loading area, and emergency overflow from four digesters into the interim filtrate
equalization basin (future Primary Clarifier No. 4). The filtrate equalization pumping
station will consist of a precast wetwell with submersible pumps and an adjacent cast -in -
place vault to house the pump check and isolation valves and a magnetic flowrneter.
Level sensing will be provided in the pumping station wetwell for automatic control of
the pumps.
BIOS©LIDS STORAGE
A biosolids storage area will be constructed northwest of the new dewatering building. The
basin will provide approximately 30 days of storage. The basin will be designed to
accommodate a pre-engineered steel roof system. Grading around the perimeter of the basin will
ensure positive containment of all biosolids. Truck washing facilities will be provided near the
loading area.

ANAEROBIC DIGESTER IMPROVEMENTS
Anaerobic Digesters 1 and 2 (AD-1 and -2) operate as primary digesters, and AD-3 and AD-4 act
as secondary digesters or sludge holding tanks. The anaerobic digesters currently are operated in
a batch mode, and pumps are used to transfer digested sludge from the primary digesters to the
sludge holding tanks. The following modifications are planned to upgrade the existing facilities
and convert the digester operation to a continuous process:
Raw sludge influent piping modifications.
Retrofit of existing supernatant decant piping to digested sludge transfer piping.
New overflow boxes and piping for each digester.
Modifications to AD-3 and installation of gas holder cover.
Upgrade of AD-4 to a primary digester and installation of a fixed concrete cover.
Replacement of recirculation pumps.
New grinders.
New boilers, heating water pumping system, and building.
New spiral heat exchangers.
Replacement of digested sludge pumps.
Miscellaneous piping modifications.
Digester Complex
Major modifications that will be made in the digester complex are summarized below.
Overflow Boxes. New emergency overflow structures will be constructed for each of the
four digesters. These will consist of overflow piping and concrete collection boxes
located on the perimeter of each tank, outside the digester building. A common
emergency overflow pipe will be directed to the filtrate equalization basin.
Sludge Heating and Recirculation. Under the new operating scheme, each primary
digester will have a dedicated spiral heat exchanger. Use of dedicated heat exchangers
and recirculation pumps will eliminate flow balancing problems between the two primary
digesters, facilitate ease of taking tanks out of service for cleaning, and provide the
flexibility to operate the primary digesters independently. Spiral heat exchangers will be
provided for each digester and will be located on the first floor of the existing digester
complex.
Digester Mixers. No modifications are planned for the existing gas mixing systems in
AD-1 and AD-2. Three mechanical draft -tube mixers will be installed in AD-4.

June 27, 2000
Boiler Building
New boilers will be provided to supply hot water to the heat exchangers. A new boiler
building will be constructed on the northwest side of the digester complex to house the
new boilers and heating water pumps. The new boiler building will have space for one
future boiler. The boilers will be fueled by digester gas or fuel oil.
MISCELLANEOUS IMPROVEMENTS
Headworks Structure
The existing headworks facility will continue to be used for flow measurement and coarse
screening. There are two spaces designated for mechanically cleaned bar screens. The
existing mechanical bar screen will remain, and a second stainless steel bar screen with
1-inch openings will be installed in the second space. The existing bar screen (1-1/2 inch
openings) located in the second space will be relocated to the bypass channel.
The existing bar screens discharge to a barrel. An electric hoist is used to lift the
screenings from the bar screens to a dumpster. A new conveyor system will be installed
to transfer screenings from the new and existing mechanical bar screens to the dumpster
at grade.
Influent Pumping Station
The pumping capacity of the influent pumping station will be increased to a firm capacity
of 22.0 mgd. IP-1 is a vertical centrifugal, nonclog type with motors mounted one floor
above on the mezzanine level. It will be replaced with a new dry -pit submersible pump
equipped with an adjustable frequency drive.
Final Clarifiers
Covers will be installed over the existing final clarifiers' eftuent launders. The covers
will be used to inhibit algal growth in the clarifier launders and on the effluent weirs and
scum baffles by blocking sunlight. The launder covers will be fiberglass -reinforced
plastic and will be composite, sandwich -type construction. They will be constructed such
that individual sections may be removed for maintenance or replacement. Inspection
ports or hinged cover sections will be provided in each panel to facilitate access to the
weirs and baffles.
Effluent Filters
Existing effluent filtration consists of deep bed, denitrification sand filtration. Acetic
acid feed provides a carbon source to promote biological denitrification within the filters.
Filter effluent flows into a clearwell and then to the ultraviolet disinfection system. Dirty
backwash water will flow into the mudwell, which drains by gravity to the influent

Page 5

June 27, 2000
pumping station. Existing blowers located adjacent to the effluent filters are to be used
for air scour of the filters.
The existing filter complex has five cells. Four cells are currently in service, and the
fifth cell will be put online. Filter internals, including the filter underdrain system, media
support gravel, and filtration media, will be added to the fifth filter cell. Piping and five
pneumatically actuated automatic control valves will be installed in the existing pipe
gallery in the Effluent Filter Structure.
UV Disinfection
Disinfection is provided by parallel banks of vertical ultraviolet light modules located in
channels following the effluent filters. Two of the three existing channels are currently in
use, and the third channel will be placed online. Three modules will be installed in each
channel currently in use and six modules will be installed in the channel to be put online.
The system will be able to disinfect the peak flow of 18.0 mgd to a coliform level of less
than 200 organisms/100 mL.
