Re: Response to Request for Additional Information - Mallard Creek WRF Non -Discharge
Permit Renewal; Permit No. WQ0013252
Dear Mr. Doby:
Please let this letter serve as Charlotte Water's response to your request for additional information
concerning an operational agreement for Mecklenburg County Park and Recreation. The following
information is in response to your letter dated April 12th and the more specific information that you
requested during our recent phone conversation:
1. The Mecklenburg County Park & Recreation Athletic Fields are located at 3001 Johnston
Oehler Rd. in Charlotte, NC.
2. Charlotte Water does not have an operational agreement with Mecklenburg County Park
and Recreation since they are also part of the Charlotte -Mecklenburg government.
Charlotte Water would like to note, however, that they do attend the required annual
training and meet all requirements as outline in our non -discharge permit.
3. The last time water was distributed to Mecklenburg County Park & Recreation was in 2013,
but Charlotte Water would like for them to remain a part of our non -discharge permit. In
2013, Charlotte Water distributed a total of 5,985,024 gallons of reuse water. Mecklenburg
County Park & Recreation received 821,304 gallons or 13.7% of the total. We have included
the consumption report from 2013 for your review.
Please let us know if you have any additional questions, or if you need any further information. If you
do, please feel free to return mail or call me directly at 704/336-4581. Thank you for your assistance
with the application process.

Re;: Request for Reduced Monitoring Frequencies for Exceptionally Performing Facilities. —
Mallard Creek WRF — Non -Discharge Permit.# WQ0013252
Dear Mr. Risgaard,
Charlotte -Mecklenburg Utility Department's Mallard Creek'WRFWas recently. approved by NCDWR for
.reduced monitoring frequencies due to Mallard's designation as.an exceptionally performing facility. As a
result, Mallard's effluent monitoring frequency for CBOD, TSS, NH3 and Fecal Coliform was reduced from
daily to 2/week. However, Mallard has been unable to reduce their monitoring frequency for these
parameters due to the requirements in Mallard's Non -Discharge Permit #WQ0013252,. which still requires
Mallard to sample daily at the effluent when our reuse system is operational.
Please consider this letter as Charlotte -Mecklenburg Utility Department's request for a minor modification to
Mallard Creek's Non -Discharge Permit # WQ0013252.. We are requesting a reduction.of monitoring
.frequencies for CBOD, TSS, NH3; and fecal coliform to match our current NPDES requlrements.since.
Mallard Creek WRF exceeds the criteria for an exceptionally performing facility as outlined in the Division of
Water Resources guidance.
Enclosed is Mallard's NPDES Permit Renewal Cover letter that requests the reduced monitoring frequency
along with the data summary that was submitted and approved by your division. We have also enclosed' a
copy of Mallard's current NPDES Permit's "Effluent Limitations and Monitoring ReqpirementsP page. Please
also let us know if you have any questions or if you need any further information. If you do, please call
Shannon Sypolt, Water Quality Program Administrator; at 704/336-4581 or Darrell Dewitt, ORC of Mallard
Creek WRF, at 704/547-0680. You. may also contact me at 704/336-4460, Thank you for your assistance

5. In the event there is a desire for the facilities to change ownership, or there is a name change of the
Permittee, a formal permit request must be submitted to the Division on official Division forms,
documentation from the parties involved, and other supporting materials as may be appropriate. The
approval of this request will be considered on its merits and may or may not be approved. The
Permittee of record shall remain fully responsible for compliance until a permit is issued to the new
owner.
The Permittee shall retain a set of approved plans and specifications for the life of the facilities
permitted herein.
The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority.
8. The Permittee must pay the annual fee within 30 days after being billed by the Division. Failure to
pay the fee accordingly may cause the Division to initiate action to revoke this permit pursuant to
15A NCAC 02T .0105(e).

Re: Permit Application for renewal of Permit #WQ0013252 — Re -Use
Dear Sir or Madam,
Please find enclosed an application for renewal of Permit #WQ0013252, for Mallard Creek
WRF, for the distribution of treated wastewater for re -use. The application also includes three copies of
the current WQ Permit and three copies of a site map, as required.
At this time, we are also requesting a slight modification in how the current permit is limited.
Currently, there is a permit limit for BOD5 set at 10 mg/I for a monthly average and 15 mg/I daily
maximum. We are requesting that this limit be changed from a BOD5 limit to a cBOD5 limit. The
NPDES Permit at this facility is limited for cBOD5 and this will allow us to monitor for cBOD5 at the plant
effluent for compliance with this standard for both Permits.
If you have any questions about the permit application, or if you need any further information,
please contact meat 704/357-1344, ext. 238. or by e-mail ate8arrell ci.charlotte.nc.us You may also
contact Darrell Dewitt, ORC of the Mallard Creek WRF at 704/547-0680 or by e-mail at

Re: N-DMR for May, 2007
Dear Sir or Madam:

No
D W E
J U L — 2 2007
NC DENR MRO
DWQ - A uifer Protection
The May, 2007 NDMR report for Permit #WQ0013252 has a includes flows from anew metering
process initiated at Mallard Creek WRF. Non -Potable Water used in Plant processes and Re -Use
water used at the Traditions Golf Course is metered by a Mag Meter on an 18" line going out of the
plant. Re -Use water that is distributed to the Traditions Golf Course is removed and then the remaining
re -use water enters the plant via an 8" pipe where it is now measured with a separate Mag meter. The
difference in the flows between these two points is reported on the N-DMR for the re -use flow.
Prior to this, Mallard Creek WRF was measuring only on the 18" Pipe as it left the facility and this
flow includes both the re -use water and the water used in the plant. The plant uses approximately
400,000 gallons of water a day for re -use. We were including a SCADA print out to display when re-
use water was used at the golf course. With the addition of the second meter we can give you a more
complete picture of what is used at the Golf Course.
The flows are still not exact - we have noticed 20,00 — 30, 000 gallons of more re -use water
coming back to the plant that was by the metered in the 18" line when the Golf Course was not using
the re -use water — this will give us a much better representation of re -use water used by Traditions Golf
Course. Please let me know if you have any questions about the new flow measurement. I can be
contacted at 704/549-0680 or by e-mail at ddewitt(a)ci.charlotte.nc.us

I. PERFORMANCE STANDARDS
The reclaimed water distribution and utilization facilities shall be effectively maintained and operated
at all times so that there is no discharge to the surface waters, nor any contamination of ground waters
which will render them unsatisfactory for normal use. In the event that the facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including
those actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or groundwaters resulting from the operation of this system.
3. Any residuals accumulated in the distribution and utilization system must be disposed in accordance
with General Statute 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the distribution and utilization system is prohibited.

materials concerns associated with this application. Groundwater comment should be
solicited prior to reissuance of this permit.
PART IV - EVALUATION AND RECOMMENDATIONS
The Mallard Creek re -use system has not been in operation for the last year. Prior to that time
the re -use system had fecal contamination issues associated with the distribution system. CMU
is evaluating the re -use lines for improper installation for their re -use application. Also they are
evaluating the reuse wet well for a potential fecal contamination location. Installing a mixing
system in the wet well to keep solids suspended in the well has helped to reduce the fecal
problem. This along with having a minimum flow through the re -use system by either
distribution or recycling will potentially aid in reducing fecal problems. In addition CMU is
investigating the distribution of re -use water as a bulk distribution product. At this time all the
above detailed issues are being evaluated by CMU Engineering Department. DWQ will be
notified of necessary changes to the system prior to installation or application.
This office recommends renewal of the permit for re -use of effluent from the Mallard Creek

Standard Operating. Procedure
Water Reuse System
Overview
Mallard Creek WRF
There are two systems that utilize Non -Potable Water (NPW) at the plant - the Water Reuse System and Non -Potable Water
supply for the plant. The Reuse Pumping Station is located downstream of the Effluent Filters and Ultraviolet Disinfection (UV).
The main purpose of the Reuse System is to supply chlorinated NPW to a local golf course. Pressurized NPW is supplied
throughout the plant for fire protection (red fire hydrants) and various pump seals and hydraulic actuators. For details on the
backup NPW system refer to the document entitled Non -Potable Water Backup System SOP.
Reuse System
The Reuse Pumping Station is located downstream of the existing Effluent Filters and UV Disinfection System. The pumping
station consists of a below -grade wetwell, with pumping units mounted on the top slab, and an adjacent Sodium Hypochlorite .
(NaOCI) storage and feed system. See Figure 1. The pumping station has an initial firm pumping capacity of 3 mgd and has the
flexibility for future expansion to 4 mgd See Figures 2 -4 in the back of this document for schematics.
Meters continuously monitor turbidq and flow per effluent limitations and monitoring requirements that are included in the
NPDES permit. Sodium hypochlonte is introduced into the pipeline conveying the reclaimed water as supplemental disinfection to
reduce fecal coliform levels to 5 per 100 milliliters and to control biological growth in the pipeline. Fecal coliforms are monitored
by taking daily grab samples at a location in the reuse pipeline where sufficient contact time is achieved from the point of
disinfection on the plant site.
The meter that continuously monitors turbidity will generate an alarm at the operator workstation if the turbidity level is high.
If the turbidity level continues to be high, then the Reuse System will switch over to potable water. The potable water mode will
provide reuse water via an 8-inch potable water line when plant effluent turbidity is high. This mode has both system pressure
based and wetwell level based control.
Turbidity greater than 8 NTU for 10 seconds shall generate an alarm. Plant effluent turbidity at 9 NTU will also generate an
alarm. If no operator action occur within 5 minutes, and effluent turbidity remains greater then 9 NTU, plant effluent mode will be
shut down and potable water mode will be initiated -
Water reuse is considered a "non -discharge alternative" and is considered by the State to be environmentally preferable to a
surface water discharge.

Mallard Creek WRF Charlotte -Mecklenburg Utilities Non -Potable Water Reuse System
Non -Potable Water System
The network of piping within the plant routes NPW to most buildings. A main line routes from the 24-inch diameter reuse line
to the doghouse. See Figure 4. The doghouse is equipped with a pressure reducing valve to regulate the NPW pressure to the
plant. From the doghouse the line branches in several direction before following the side of street to the RAS/WAS Pumping
Station. A trunk line tees from this line and routes down the street toward the Influent Pumping Station.
Lines of various diameter route to any building or structure that requires seal or flush water, a hose connection for equipment
cleanout, or for water cannons (at Equalization Basin and Day Tanks).
Gate valves are located at various locations within the network In many cases they can be shut off to isolate a specific
building or several valves can isolate large areas within the plant.
Backflow Preventers
The Biosolids Handling Building and the RAS/WAS Pumping Station are equipped with bacldlow preventers. Potable water
within these buildings is a backup to the non -potable system should the pressure of NPW be reduced below set point.
Automatic Pump Operation
Jockey Pumps
There are a total of six pumps at the wetwell. Two pumps are designated as jockey pumps and are the smallest. See Table 1.
They are controlled by pressure reducing valves and are designed to energize when demands are low. The PLC designates the
lead/lag sequence of these pumps.
High Pressure Pumps
As demand increases larger pumps are used to maintain pressure set point. Four pumps are available with two pumps set to
operate from Adjustable Frequency Drive (AFD) motors. The PLC designates the lead/lag sequence of the chosen AFD pumps.
One of the remaining two pumps energize at full speed should demands continue to increase.
Pump Sequence
Increasing Demand
When demand is low the lead jockey pump is in operation. On increasing demand the designated lead AFD pump is energized
to operate at minimum speed. The start of this pump causes the jockey pump to shutdown. The AFD pump changes speed to
maintain a header discharge pressure of 150 psi (factory set).
As demand continues to increase and pressure drops to 140 psi (factory set) the designated lead constant speed pump
energizes. The AFD pump modulates to maintain a pressure set point of 150 psi. A continued demand will cause the AFD pump to
operate at maximum once again. Once this occurs the standby constant speed pump energizes.. .

The following control descriptions explain the control scheme for the PLC program and
the OIU's.
BOLD CAPITALIZED ITALICS indicates Magellis setpoint descriptions.
Pressure Control of Reuse Pumps.
The pump control scheme for the reuse system is a pressure control type system based
upon measured discharge header pressure as follows:
1) Pumps RWP-3 through RWP-6 will operate to maintain a constant pressure in the
discharge header measured by the discharge pressure transmitter PIT-100. The
two smallest pumps, RWP-1 and RWP-2, described as jockey pumps, will be
controlled by pressure reducing valves on the pump discharge.
2) Pumps RWP-3, RWP-4, RWP-5, and RWP-6 are capable of either constant speed
or variable speed operation. AFD-1 shall be manually selected to control either
RWP-3 or RWP-4, and AFD-2 shall control either RWP-5 or RWP-6.
3) If both AFDs are in the AUTO mode, the PLC will automatically designate a lead
AFD. The other AFD will be designated by PLC logic as standby. The remaining
two pumps will be automatically operated in constant speed mode by the PLC to
meet additional capacity demands of the system.
4) Initial reuse pumping station operation is no pumps running. With both jockey
pump's selector switches at MCC "MY selected to AUTO, the PLC will automatically
designate one of jockey pumps RWP-1 or RWP-2 as the lead. This lead jockey
pump will run continuously. The lead jockey pump will stop only when manually
selected at MCC "MY, upon start of the lead variable speed pump as described
below, on low water cutoff elevation in the wetwell, or high reuse turbidity shutdown.
The PLC will automatically alternate the lead pump following each jockey pump stop.
If only one pump is in AUTO, it will always be the lead.
5) Discharge (system) pressure shall be maintained at 150 psi (CONTROL SP) as
measured by the discharge .pressure transmitter PIT-100.
a) On increasing demand, system pressure will drop. At 145 psi (AFD START), the
lead variable speed pump will start and operate initially at minimum speed. After
lead AFD start, the PLC will stop the lead jockey pump . The PLC shall
modulate the lead variable speed pump's speed to maintain 150 psi in the
discharge header.
b) If system demand decreases, the lead variable speed pump will reach minimum

speed, discharge header pressure will rise above 150 psi, and pump station
discharge flow rate will decrease. At 0.6 MGD (AFD SP), as measured by
magnetic flowmeter FIT-100, and 155 psi. (AFD STOP SP) the lead variable
speed pump shall be shut down, and the new lead jockey pump (previous
standby pump) will start.
c) If system demand increases, the lead variable speed pump will reach maximum
speed and discharge header pressure will decrease. At a 140 psi (CONSTANT
SPEED PUMPS START SP) header pressure (and with lead variable speed
pump at maximum speed), the designated lead constant speed pump will start.
The lead variable speed pump shall modulate to maintain 150 psi.
d) If system demand continues to increase (and with the lead constant speed pump
running and the lead variable speed pump at maximum speed), the standby
constant speed pump shall start at 140 psi (CONSTANT SPEED PUMPS
START SP) after a preprogrammed time delay.
e) If system demand decreases (with two constant speed pumps running and the
lead variable speed pump at minimum speed), the discharge header pressure
will rise above 150 psi, and pumping station discharge flow rate will decrease. At
2.9 MGD (LEAD CONSTANT SPEED PUMP SP) and 160 psi (LEAD
CONSTANT SPEED STOP SP), the lead constant speed pump shall stop. If
system demand continues to decrease (and the lead variable speed pump is at
minimum speed), then the remaining constant speed shall stop at 1.8 MGD
(LAG CONSTANT SPEED PUMP SP) and 160 psi (LAG CONSTANT SPEED
STOP SP). The lead AFD will then shutdown as described in b (above).
Wetwell Level Control of Reuse Pumps.
If wetwell level, as measured by the ultrasonic level transmitter, LIT-10.0, drops below 7
feet (INITIATE WETWELL LVL CONTROL SP), pump operation shall be limited and the
following wetwell level control logic shall override the system pressure control logic.
1. During wetwell level control, the designated lead variable speed pump (through PLC
logic) shall operate at minimum speed.
2. At a wetwell level of 7 feet, any running constant speed pumps shall be shut down.
(If only one constant speed pump is running) then only one shall shut down). Upon
stopping of the constant speed pump, pressure in the system will decrease.
However, the lead variable speed pump shall maintain minimum speed.
3. If wetwell level continues to rise (with reduced pumping capacity), the constant
speed pump shall restart at a wetwell level of 8 feet (WETWELL LOW LEVEL RE-
START PRESSURE CONTROL SP), and the variable speed pump control logic

shall then revert back to system pressure based control.
4. A wetwell level of 5 feet (WETWELL LOW LEVEL CUTOFF SP) shall bean
absolute low water cutoff for all pumps, regardless of system pressure. Pump
control logic shall not be re -enabled after a low water cutoff until wetwell level has
risen to above 5.75 feet (LOW LEVEL CUT-OFF RESET SP).
Sodium Hypochlorite (NaOCI) Feed Control.
Metering of sodium hypochlorite to the pump station discharge line will be automatically
controlled via the PLC. The sodium hypochlorite pumps SHFP-1 and -2 will be
automatically started (ON/OFF) whenever a reuse water pump is running and reuse flow
is above'/2 %. Metering output (0-100%) and lead/standby selection of the sodium
hypochlorite feed pumps will be controlled by the PLC based upon measured discharge
flow from flowmeter FIT-100, 80% pump stroke length (FEED PUMP STROKE LENGTH
SP), and 3 ppm dosage (DOSAGE SP) entered by the operator at either OIU.
The PLC will automatically calculate the pump speed output based upon the following
formula:
Pump % _ (Flow Rate fMGDI x Dosage fmq/Ll x 8.34) _ (Stroke Length x (38.8x24)) x 100%
Speed (1.175 x 8.34 x .1117)
400
Note: The constant 1.175 is the specific gravity of hypochlorite solution.(at 12.5 Trade
%). The constant .1117 is the weight % (of 12.5 Trade % solution). The constant 38.8
reflects the maximum pump capacity (in gallons per hour) and is specific to the installed
chemical feed pumps. All three values are hard -coded into the PLC logic and are not
operator adjustable.
Attached are several sheets illustrating the relationship between pump speed, dosage,
and flow rate.
High Reuse Turbidity Shutdown.
Reuse turbidity greater than 10 NTU (REUSE PUMP STATION SHUT -DOWN SP) shall
generate an alarm at the operator workstation computer and shall stop all pumps until
the alarm is reset .(at the operator workstation computer) by the operator.

REVISED May 19, 2000
The plant effluent mode is the normal mode. The potable water mode will provide reuse
water via an 8-inch potable water line when plant effluent turbidity is high. This mode
has both system pressure based and wetwell level based control.
1. Plant effluent turbidity greater than 8 NTU (PLANT EFFLUENT TURB ALARM 1
SP) for 10 seconds (TIME DELAr shall generate an alarm. Both alarm setpoint
and time delay shall be adjustable from either OIU. These alarms will be in addition
to the reuse turbidity alarms described above.
2. Plant effluent turbidity shall also generate an alarm at 9 NTU (PLANT EFFLUENT
TURB ALARM 2 SP). If no operator action occurs within 5 minutes (TIME DELAY)
and effluent turbidity remains greater than 9 NTU, plant effluent mode will be shut
down and potable water mode will be initiated. Plant effluent mode is the existing
pressure -based control mode with wetwell level control (low level protection).
3. Sluice gate position (opened, closed) shall be displayed on the operator work station
computer. Gate open/close failure (time delay) shall be generated in the PLC and
alarmed at the control room OIU.
4. Power failure (as detected by PLC-50) will automatically initiate potable mode upon
restoration of power. This may be overridden by the operator, see below.
5. Upon power failure (as detected by PLC-50), the PLC will automatically initiate a
close command to the potable waterline control valve. The valve shall remain closed
until potable water mode is re -initiated (upon restoration of power). The valve is
powered from Power Panel P2 that has standby power from the plant engine
generators.
6. The operator, from the operator workstation computer only, shall be able to select
either plant effluent or potable water mode of operation, overriding the control
system. The operator workstation computer shall display the current mode of
operation. Even if the operator overrides potable water mode, all turbidity alarms
_shall remain active. Following an operator override, if plant effluent turbidity remains
greater than 9 NTU for 5 minutes (RETRY POTABLE WATER MODE DELA)q, the
system shall attempt to enter potable water mode one additional time. If again
overridden by the operator, the operator workstation computer shall alarm and
display "SYSTEM UNDER OPERATOR CONTROL. REUSE TURBIDITY
CONTROL DISABLED".
7. Upon initiation of potable water mode, the PLC shall issue a close command to the
sluice gate. At the same time, the PLC shall open the potable water -modulating
valve for approximately 1 second, then wait 25 seconds for potable water system
pressure to stabilize. The valve will then repeat the cycle until 42 psi (POTABLE
WATER SYSTEM HOLDING PRESSURE (MIN) SP) potable pressure is

established. The valve will then hold position until the wetwell reaches 15.2 feet
(WETWELL LEVEL (STOP FILL) SP), then close. When the wetwell reaches 14.5
feet (POTABLE WATER VALVE WETWELL LEVEL (START FILL) SP), the wetwell
fill cycle will start again.
Under no conditions must potable water system pressure drop below 20 psi,
regardless of reuse system demands. Reuse pumps shall continue to operate under
(installed) pressure -based control. If plant effluent averages less than seven (7)
NTU (POTABLE WATER MODE RESET SP) for 60 minutes (TIME DELAY), the
system shall re -initiate plant effluent mode. The PLC shall average plant effluent
NTU using 30 second samples. Upon re -initiation of plant effluent mode, the PLC
shall issue an open command to the sluice gate and simultaneously close the

I. PERFORMANCE STANDARDS
The reclaimed water distribution and utilization facilities shall be effectively maintained and operated
at all times so that there is no discharge to the surface waters, nor any contamination of ground waters
which will render them unsatisfactory for normal use. In the event that the facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including
those actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or.groundwaters resulting from the operation of this system.
Any residuals accumulated in the distribution and utilization system must be disposed in accordance
with General Statute 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the distribution and utilization system is prohibited.

The Groundwater Section has reviewed the subject renewal request for the continued application
of reclaimed (reuse) water derived from several waste sources. According the permittee, the treated
wastewater is predominately domestic, commercial, and some industrial components. The commercial
sources include restaurants, laundries, a hospital, and a large university. The industrial wastewater is
generated from "one Organic Chemical Manufacturer and a Metal Finishing facility". The previous
permit issued May 29, 1997 allowed the distribution of the reclaimed water for process/cooling water,
decorative ponds, fountains, fire fighting, dust control, soil compaction for construction purposes, street
cleaning, vehicle washing, etc. In addition the Traditions Golf Course and the Mallard Creek Community
Park were approved to receive reclaimed water via irrigation.
Since a percentage of the reclaimed water has industrial components, it is considered industrial
wastewater under 2H.0203(19). The Groundwater Section usually recommends that no industrial
wastewater be applied to site(s) when the vertical separation between wastewater and water table is less
than three (3) feet. This condition was not included in the permit issued May 29, 1997 and is
recommended to be added as stated in condition no. 2 below.
Charlotte -Mecklenburg Utility Department shall assume responsibility for enacting and
upholding the regulatory requirements for its system (including application areas) as required tinder
I5A NCAC 2H .0219(k)(2).
The Groundwater Section recommends the following conditions be included in the permit:

1. Applicable Well Buffer Requirements:
*Buffer requirements for reclaimed water are specified by regulations in 15A NCAC 2H
.0219(k)(2)(B)(V), Waste Not Discharged to Surface Waters. Under these rules there shall be a
100 foot buffer from the edge of spray influence and any potable well. "There shall be a 10 foot
buffer from the edge of spray influence and any nonpotable well'. Non -potable well(s) must have
warning label(s) stating non -potable or not for human consumption.
2. Vertical Separation Requirements:
*Waste application activities shall not occur on any site when the vertical separation between
depth of application and the water table is at less than three (3) feet. Verification of the water
table elevation can be confirmed by water level readings obtained from auger boring(s) which
must be done within 24 hours, prior to application of wastewater. The number of borings
advanced shall be sufficient to adequately characterize water table conditions across the entire
application site(s). Any open borings must be properly filled with native soil, prior to application
to decrease the chance of any waste contaminating the groundwater.
3. Applicable Boundaries:
*The COMPLIANCE BOUNDARY and REVIEW BOUNDARY for the waste disposal area(s)
is specified by regulations in 15A NCAC 211, Waste Not Discharged to Surface Waters,
specifically .0219(k)(2)(B)(IV). The Compliance Boundary and the Review Boundary for
groundwater shall be established at the property boundary. An exceedance of Groundwater
Quality Standards at or beyond the Compliance Boundary is subject to immediate remediation
action according to 15A NCAC 2L .0106(d)(2).
4. Additional Requirements:
Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.

Inspection Summary: (additional comments may be included on attached pages)
The water reclamation facility appears to be operating satisfactorily. The facility has not distributed flow to the
reclaimed system since an illegal PCB dumping was detected at the plant on February 61h, 2014. This facility is
:also a source under Charlotte Water's Residuals permit WQ0000057, so residuals processing and storage areas
were also viewed. All Mallard residuals are currently disposed in an appropriate landfill until decontamination
is complete.
The Traditions Golf Course and Mallard Community Park are the only off -site facilities currently permitted to
receive distributions. Reclaimed water may be utilized within the plant for specified activities. .
Please note:
• Calibrate the reclaimed system flow meter and conduct the annual training event prior to
resuming distribution.
• -The MRO should be informed of any changes to the contact information noted above. Staff was
informed of a plant ORC change later this year. Henry Eudy currently with the 12-mile Creek WWTP
in Union County is expected to replace Darrell DeWitt, who: will be going to the McDowell WWTP.

For further clarification, while the daily limit of 25 (geometric mean) was exceeded on the days noted, the monthly
averages for May, June September and October were well below the limit of 14 (geometric mean). As I mentioned in
our phone conversation, no reuse water containing elevated fecal counts had been released to the distribution system
and the operator and other personnel were keeping this office informed as they actively addressed the problem. In
consideration of these factors, I determined that the issuance of a Notice of Violation was not warranted.

Audit noted non compliance was marked for Fecal violations. The City forms are measuring fecal daily limits not to
exceed 25 and monthly limits not to exceed 14. The date of the violation and test results are included below:
• May 11, 2010 reading of 51
• June 3, 2010 reading of 94, June 14, 2010 reading of 28 and June 25, 2010 reading of 49

From our telephone conversation this morning, you indicated that Mallard ReUse was considered temporarily out of
compliance and each violation was evaluated separately. You also stated that these violations were reported timely and
there was no environmental harm and these were not worthy of an official state violation.
Please confirm back that the State did not consider any of these months non compliant, please feel free to add any

Re: Reclaimed Water Spill from Mallard Creek WRF — Permit #WQ0013252
On Monday — August 15, 2011—a call was made to Charlotte Mecklenburg Utility Department (CMUD)
from a contractor that was boring underground cable had struck and ruptured a water line at 11:30 am.
Field Operations arrived at the site at 12:00 noon and started working to find the cut-off valves to repair
the line. It was determined that this was the re-claimed water distribution line from Mallard Creek WRF.
A crew was brought in to try to find the cut-off valves (they needed to be dug up) when the valves were
found the valve key would not work on the valves. Mallard Creek WRF was notified and stopped all
water distribution from the plant. The repair was then completed.
The line was initially ruptured at approximately 11:30 am and.the final repair was completed at 6:30 pm.
During this time approximately 121,125 gallons of re-claimed water flowed across park land and finally
into Stony Creek. Mecklenburg Co. was notified and Jeffery G. Mitchell, Environmental Specialist, with
the Water Quality Program, LUESA, arrived at Stony Creek and collected samples from the creek on
Tuesday August 16, 2011 at three different sites.
Attached with this document is a copy of an e-mail from Jeffrey Mitchell in response to an e-mail from
Sheryl Haig with CMUD. Sheryl's e-mail includes a map showing the location of the re-claimed water
line break, the path of the water to Stony Creek, the location of the roads in the area, and the locations
where LUESA and CMUD collected their sample's. Please let me know if you have any questions about
the map or the e-mail's.
A second e-mail from Sheryl Haig, included with this report, includes the Laboratory Information
Management System (LIMS) page with the sampling results from samples collected in the field by CMUD
personnel. Please note the time the samples were collected. All of the samples were collected after the
break was repaired, and the samples collected the night of the 15th were from areas where the final
clean-up was being completed.
Also, included with this report is a copy of the on-line SCADA report for Total Residual Chlorine and for
suspended solids on the day the line break occurred. These graphs show that the solids were within
compliance and the residual chlorine was maintained for the duration of the spill. Since the spill crossed
several hundred feet of land before entering the creek, we do not feel that the residual chlorine would
have had an adverse impact on the stream.
Upon investigation of why this occurred, it was discovered that the local utilities locator had indicated
that this line was across the street from where it was actually located. We have contacted the locating
service to correct this error. We are also in the process of firming up the locations of the valves along
the re-claimed line and painting all of these purple to indicate these are for the re-claimed line.

If you have any questions about this report, the sampling results, or the map
-MA /201-9144 or by a -mail at [e-mail]. If you have any 4U, JUWIla UUMUL VVIIUL VVa
occurring at the plant during the line break, please contact Darrell Dewitt, ORC of Mallard Creek WRF, at

Thank you. I was working on my work order and was unsure of the true upstream sampling location.

Sample IDs above correspond to fecal samples that I collected. As your map shows, all of my samples
are actually downstream of the discharge location. The naming of the samples was based on my
understanding that the discharge occurred at the intersection of Mallard Creek Road and Johnston
Oehler Road and ran down the side of the road to the creek (Attached: Image 1-3). -My upstream

sample (Stony Creek-UP)is actually a downstream sample that is closer to the discharge source, but
excludes the tributary that I sampled that runs parallel to Mallard Creek Road. My downstream sample
(Stony Creek-DN) includes the water from the tributary. The Stony Creek-Trib sample was sampled
within the actual side tributary and does reflect any of the water from the stream that received the
reuse water discharge. I collected the sample to ensure the tributary was not impacting what I thought
was my downstream sample.
I used YSI #5 for the collection of the physical parameters, and all probes checked in within the
acceptable range for the data to be usable.
After you showed me the location of the discharge, I believe what I observed in Image 1 was a shutoff
valve for the reuse water piping.

in it but, it was actually just a trench filled with the reuse water from the main break still discharging.
When I looked at the sample location today it was dry with only one small pool of water remaining at
the bottom of the hill and was not running to the creek below it. This site is marked with a pink line and
a red circle (see map). The result from this fecal is not representative of the creek it is clearly just reuse
water and whatever was picked up in the trench through the woods.

I was able to get an upstream sample from the creek today ( see upstream 1) and run field tests (pH
6.40, Dissolved Oxy 10.52 @ 26.8 C, Cond 84.4). The pH was a bit low but may have been low ions in the
creek because the instrument response was very slow to get the reading. The DO was high but, the
creek was very clear and open, getting a lot of sunlight.
Jeff Mitchell from LUESA was also out picking up samples today and I've marked the areas where he
collected fecal samples on the map. Since Jeff had already collected a downstream sample and 2 other
samples in between, I did not attempt to collect a downstream as it was a difficult area to access on the
other side of Mallard Creek Rd. Jeff looked at the maps with me today and also said he would share the
results for the fecal samples and field parameters with us. Either Emily or myself will send Jeff the
results for the Upstream Fecal and field parameters I collected.

CMU Field Results:
Dawn, Jimmy Brado collected the fecal sample at the site of the reuse main break. Field ops had shut
down the main and were pumping out the water around the pipe. The pipe was exposed and
contaminated with soil debris where Jimmy took sample. This explains the Fecal result at this location.

Your letter regarding false -positive turbidity readings was received in -this office on November 18, 2009. The
SCADA reports that you enclosed support your conclusion that these brief, occasional readings were the result
of water turbulence. If and/or when the turbulence occurs again, please provide SCADA documentation upon
submission of the monthly NDMR form.

Re: Mallard Creek WRF, Permit #WQ0013252
Dear Ms. Finley,
IJ
DWQ-
As I discussed with you on the phone a couple of weeks ago, Mallard Creek WRF has
encountered a problem with a false positive for turbidity showing up twice in the month
of September, 2009. The permit limit for turbidity is 10 ntu. This is monitored
continuously by the plant by a turbidity meter that sends the results to the plant SCADA
system where the maximum, minimum and average turbidity are summarized and the
maximum turbidity each day is downloaded into a spreadsheet for reporting on the
NDMR.
On September 4, 2009 the turbidity maximum was recorded as 11 ntu, this occurred
momentarily when the demand for re -use water increased and a second pump started up.
Right after this jump the turbidity immediately dropped back to normal, with an average
turbidity for this day of 0.68 ntu's. Again on September 5, 2009, when the re -use
demand increased and the second pump engaged the turbidity shows a momentary jump
to 17 ntu's with an immediate drop back as the water turbulence dropped. The actual
average turbidity for this day was 0.97 ntu's.
We believe both of these occurrences are due to the water turbulence when the second
pumps started causing the turbulence, and that this is not indicative of true turbidity. The
effluent suspended solids on both days was <2.5 mg/l. Due to the issues with these
results, they will not be reported on the NDMR, instead the second highest recorded
turbidities will be reported for September, 2009.
Enclosed with this letter of explanation, are copies from the plant SCADA report
showing the turbidity (in purple) and the effluent discharge pressure to show how the
turbidity increases occurred when the pump pressure went up.

Inspection Summary: (additional comments may be included on attached pages)
The reclamation system is operating properly and is generally in compliance with the conditions
of the permit. Records were in good order. A portion of the permitted daily flow is used within
the plant. The Traditions Golf Course continues to be the only external user. Currently, there is
no mechanism to determine the volume of water used by the golf course. This needs to be
addressed, particularly if other users are added in the future.

Comment: Reclaimed water is initially treated under Permit IaNC0030210. Up to 250,000 gallons
per day is distributed through the reuse line. Effluent that does not meet the parameter limits
specified in WQ0013252 is discharged under the general permit or is reintroduced to the head
works of the plant for further treatment and potable water is substituted in the reuse line.

Subject: Installation of valve for Permit #WQ0013252, Mallard Creek WMF
Hi Peggy— it was nice talking to you earlier today. The following e-mail summarizes what we are proposing to install. As
I mentioned, John Lesley was at Mallard Creek WRF yesterday and looked at where they planned to install the flapper
valve.
The proposed flapper valve would be installed at the entrance to the wet well for the re -use pumps. We are planning to
inject the sodium hypochlorite at this location to prevent the vapor locking that is occurring at the current injection
point. The flapper valve will prevent wastewater from the wet well from returning back into the effluent of the plant. If
you can approve this, we would like to go ahead and purchase this equipment. We feel like this will resolve most of the
fecal coliform violations we have had on the re -use water line.
Thank you for your consideration,
Dawn Padgett

Hello , had the state inspection today with John Lesley. I told him about our plans with the installation of the flapper
valve. We gave him a detailed look of the well and piping configuration and explained to him how the new valve would
project against any chlorine flowing back into the effluent. He thought it was a great idea and basically gave us the green
light. Dave and Maggie if you guys would start he procurement process that would be great.

Re: Permit #WQ0013252
Dear Ms. Finley,
It was very nice to meet you last Thursday, 4/13/06. I appreciate you coming out to the
Mallard WRF to meet with Darrell Dewitt and I to discuss starting the Water Re -Use
System back up. Following is a summary of our conversations on the telephone and
during the inspection at the facility. Please let me know if I have anything wrong or if
there is other information I need to include for this summary. When we are both in
agreement on the processes and procedures at place at the facility, I will submit a final
version identifying the information that is required for compliance with Permit
#WQ0013252.
1. The facility will be distributing 250,000 gallons a day through the re -use line.
What is not used by the Golf Course will be returned to the plant for
treatment. The flows reported on the NDMR-1 form will be the re -use waster
actually used by our customers during that month.
2. If turbidity limit is exceeded. The plant will immediately switch to potable
water to be distributed to through the re -use lines until the turbidity is reduced
back into compliance with the re -use limit.
3. The highest recorded turbidity for the day will be reported on the NDMR-1
report.
4. The residual chlorine will be measured continuously. Since this system is not
linked into the SCADA system for continuous results at this time, the residual
chlorine will be recorded by an Operator on -site every two hours and logged.
The log reports will be available during inspections of the facility.
5. Along with the residual chlorine log results, residual chlorine samples will be
taken daily, by lab personnel, and the results from the tests submitted with the
DMR.
6. We would like to request a Minimum Detection Limit (MDL) for the residual
chlorine of 0.10 mg/1.
7. Samples taken at the effluent of the treatment plant for ammonia and TSS will
be used for reporting compliance with the ammonia and TSS limit s in the Re-
use non -discharge permit.
8. BOD samples should be taken on the re -use line to show compliance with
BOD limits.
9. Sampling should be conducted on the re -use line on Monday - Friday.
Operators working at the plant on the weekends must watch the re -use line to

make sure nothing out of the ordinary occurs. If the discharge characteristic
changes over the weekend procedures must be in place for stopping the re -use
discharge and replacing this with potable water.
10. We should submit a request to amend the current Permit Limits from BOD to
cBOD. If this is approved than we will be allowed to submit effluent cBOD
results is lieu of sampling the re -use lines for BOD.
Thanks again for your assistance with this process, please let me know if there are any
other actions we will need to complete to satisfy the Permit Requirements.
Sincerely,
Dawn Padgett

Supplemental Guidance for the Determination of
BIOCHEMICAL OXYGEN DEMAND (BOD)
and
CARBONACEOUS BOD (CBOD)
in
Water and Wastewater
March 1998
Background
a.. the purpose of the biochemical oxygen demand (BOD5) test is to measure the potential of
wastewater, and other- waters to deplete the oxygen level of'receiving waters Wastewater treatment
plant operators also use the BOD5 test to determine the efficiency of their- plant by measuring BOD5 of
.the influent, and ofthe effluent, and calculating the percent removal, the BOD5 test may also be used
to test waters other- than wastewaters to determine their oxygen -depleting potential..
b. Oxygen is required (used up, depleted, consumed, assimilated) by microorganisms as they
assimilate various organic and inorganic materials in water. Some of those materials contain reduced
forms of'nitrogen. Collectively these materials are called nitrogenous materials, and they are
consumed by nitrifying bacteria. Ifthose nitrifying bacteria air, inhibited, usually using a pyridine
compound, the test measures only carbonaceous organic material, and is referred to as carbonaceous
BOD5, or- CBOD5," Carbonaceous material is that consumable material which does not contain
nitrogen.
b. While the term `BOD" technically refers to the oxygen uptake demand of contaminated
water, the term is commonly used to refer to the organic and inorganic materials consumed by
bacteria, as if 'BOD" is a contaminant in the water. For- example, wastewater treatment plants report
"percent removal of'BOD" as an indication of'how well the plant is performing.. Ihis document
occasionally uses BOD and CBOD in such a manner.
c.. Many biological treatment plant effluents contain enough nitrifying bacteria that thew
consumption of nitrogenous material (material containing nitrogen) is significant. Because
nitrogenous demand has historically been considered an interference (i.e,, the primary purpose of the
13OD5 test is to measure carbonaceous material ....nitrogenous material can be measured by other- tests
such as ammonia, nitrate -nitrite, and total Kjeldahl nitrogen), the CBOD5 test is preferred for- samples
of secondary effluent.. For- regulatory programs, however, the bottom line is that the test specified by
the regulator must be run.. Irf some cases, the regulator, may require both BODs and CBOD5 data
' Reduced forms of'other inorganic materials such as sulfides and ferrous iron are also oxidized during both BOD5 and
CBODS tests and would create a positive bias if'present in the sample or dilution water. Other inorganic materials,
such as hexavalent chromium, copper, and free chlorine may create a toxic environment for the bacteria and cause a
negative bias.. If these types of interferrents cannot be eliminated prior to running the BOD5 or CBOD5 test, their
presence can be mentioned in test reports.,

d.. It would take the bacteria in a wastewater sample 20-plus days to assimilate all the
consumable material in a water sample. Because it is impractical to spend 20 days analyzing a
BOD sample, a 5-day test has been established as the standard (hence, BOD,). Depending on the
specific waste stream, 60-70% of the available material is consumed in a 5-day period. Another
test that measures the oxygen requirements of water is chemical oxygen demand (COD) which, in
a relatively shoat time, measures essentially 100% of the chemically oxidizable material.. One can
expect BOD5 and COD results for the same sample to be related, the BOD, value being perhaps
60-70% of the COD value depending on the nature of the sample.. Also, because BODS is a
measure of nitrogenous and carbonaceous material, and CBOD5 is a measure of'only the
carbonaceous material, one would also expect a correlation for BOD5 and CBODS for a given
sampling site, Indeed, Table 1 shows there is a very consistent ratio of'BOD5 to COD, and BOD5
to CBOD5 for a given type of sample (in this case, performance evaluation, or PE samples fiom
EPA's Water Pollution, or WP Studies). One should be able to determine BOD5/COD5 and
BOD,/CBOD5 ratios for a given waste stream, although the ratios may not be as constant, or of the
same magnitude as those shown in Table 1, Table 1 also shows a consistent ratio between BOD5
and total organic carbon (IOC) for a given sampling site. If a relatively consistent BOD5/COD
ratio can be established for a given sampling point, the COD test can be used as a screening
process for estimating the BOD5 ofthe same sample. When used for this purpose, the Hach
Company's recently developed (but not yet EPA -approved) manganese -III COD method can be
used rather than an approved method, all of'which generate considerable contaminated waste.

e. the B4ODs test is widely used to determine the degree to which a waste stream will
contribute to pollution of receiving waters by depriving organisms in those waters (e.g., fish) of
their source of'oxygen, The BODS test is of'prime importance in mgulatory programs and in
determining the overall health of'receiving waters. On the other hand, of all the tests done by and
for, wastewater dischargers, BOD5 is arguably the most likely to result in invalid data if adequate
precautions are not taken to assure quality of test results., The purpose of'this document is to
provide supplemental guidance to assist labs in following quality control procedures in published
analytical methods, If used properly, those methods and procedures will provide evidence that the
measurement of'BOD5 is in control, and that the results meet established data quality objectives.
f. Several technical terms used in this document may not be familiar to some readers.
When in doubt about the meaning of'a technical term for the purposes ofthis document, check
Appendix I of'Ecology's Procedural Manual for the Environmental Laboratory Accreditation
Program (Glossary of QA/QC Terms), Reference F to this document.
2. Approved Methods
a. The BOD5 test is normally required by a regulatory program that is governed either,
directly or- indirectly by Chapter- 40, Code df'Federal Regulations, Part 136 (40 CFR 136) which
concerns the National Pollutant Discharge Elimination System (NPDES).. 40 CFR 136 allows the
use of four analytical methods for reporting BOD5 and/or CBOD5: EPA Method 405..1; Standard
Methods 521013; USGS Method I 15'78; and AOAC Method 973.44 EPA Method 405.1 refers the
user to Standard Methods 5210B for specifics on conducting the test.. It is Standard .Methods
5210B or its derivative that is most commonly used in environmental laboratories.. It must be
emphasized that this guidance document is not an analytical method, and that use of this guidance
document or any part of it is not required by Ecology., This supplement was written with the intent
that implementation of its suggestions would meet requirements for NPD.ES and other- discharge
monitoring programs. It is not intended to be used as a stand-alone procedure, but rather as a
supplement to one of the EPA -approved BOD5 methods. If a simplified BOD5 method is needed,
the reader is encouraged to review References 11 c and 11 d on page 28 of'this document.. Both
satisfy the requirements of 40 CFR 136 since they follow Standard Methods 5210B..
b.. All BOD5 methods approved by EPA are based on determination of'oxygen depleted by
bacteria in samples during a 5-day2 period, in the dark, at 20 f I' C as those bacteria consume
organic materials in water samples. BODs samples are normally incubated in 300-mL BOD
bottles, and are diluted if necessary to allow at least 1.0 mg/L of dissolved oxygen to remain at the
end of'the 5-day incubation. To be a valid test, at least 2.0 mg/L of oxygen must be depleted
during the incubation, and at least 1..0 mg/L must be retained at the end of the incubation period.
If necessary, samples must be pretreated to assure proper pH, temperature, and absence of'toxic
materials (e.g.., chlorine) thus creating a suitable environment for survival of the BOD-consuming
bacteria. The fbregoing are requirements of'all EPA -approved BODS methods.
2 The incubation period is generally considered to be 5 days f 2 hour's, but the method does not specify the
tole[ance
