A. (2.) CHRONIC TOXICITY MONITORING (QRTRLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be
performed as a Ceriodaphnia dubia 7day pass/fail test. The tests will be performed during the months of
January, April, July, and October. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP313.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than
30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of
the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required;
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert
to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified
to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last
day of the month following the month of the initial monitoring.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of'the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24.hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1 /24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.
Version 612012003

NPDES Permit Requirements
Page 2 of 16
In accordance with (4) above, influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a'24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWO or "the Division"
The Division of Water Quality, Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility, or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered =1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Instantaneous flow measurement
A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total
discharge.
Version 612012003

Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which

October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24.hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1 /24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found.
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as ."Daily
Maximum," in Part I of the permit.
d. The "average. annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured .during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during.such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. Thin
limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean _(weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample -is taken during any calendar day. the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the, sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part I.
f. The "quarterly average concentration" is ' the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

Part II

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "instantaneous flow measurement is a measure of flow taken at the time of sampling, when
both the sample and flow will. be representative of the totaldischarge.
c. - A "continuous flow measurement'.' is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample:. A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow'measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1 /24.of the expected total daily flow at the treatment .system, or
(3) a 'single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. ,In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the, system in number- of days. However, in no case may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour.sampling"period:
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken. manually. Grab samples must ' be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to, the number of individual values. The geometric mean is
equivalent to the antilog .of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

Subject: NPDES Permit Renewal Application
Permit NCO083119
Coddle Creek WTP
Cabarrus County
The Division received your permit renewal application on April 5, 1999. Thank you for
submitting this package in a timely fashion.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff.
That staff member will contact you if further information is needed to complete the permit
renewal. I regret to inform you that we have lost several staff members in the past few months,
leaving the NPDES Unit with four vacant positions. This staff shortage is causing delays in our
processing of permit renewals. Our remaining staff are currently reviewing Authorizations to
Construct, speculative limit requests, major permit modifications and 201 plan reviews ahead of
permit renewals. This is necessary due to a variety of factors,. including mandatory deadlines in
the statutes that govern our program.
If this staff shortage delays reissuance of NC0083119, the existing requirements in your
permit will remain in effect until the permit is renewed (or other action is taken by the Division).
We appreciate your patience and understanding while we operate with diminished resources. If
you have any additional questions concerning renewal of the subject permit, please contact me at
[phone], extension 511.

RE: Coddle Creek Water Treatment Plant
NPDES Permit NCO083119
City of Concord, Cabarrus County
Dear Mr. Weaver:
Enclosed please find the NPDES permit renewal package for the City of Concord's Coddle
Creek Water Treatment Plant. As you and I discussed during our recent telephone conversation,
this is the first renewal of the NPDES permit. Generally, the water plant produces 6.0 million
gallons per day of potable water for public consumption through our water distribution system.
The plant treats raw water from the Coddle Creek Reservoir with contact clairifiers and mixed
media filters. Both processes, clarification and filtration require backwashing. The filters must
be backwashed with potable water. However, the clarifiers are backwashed with raw water from
the reservoir. The backwash is treated onsite by two (2)-settling basins prior to discharge into
Coddle Creek, downstream of the reservoir. Approximately 50 percent of discharge is raw water
from the clarifiers.
Charles, as we discussed, we believe that during this first renewal of the permit is the time to
address the flow limit. We understand that the original DWQ/NPDES staff reports did not ask
for or recommend flow limits. We also understand that several water treatment plans with
settling basins similar to ours are permitted without flow limits. With this precedent, together
with the compliance history of the facility, the City of Concord hereby requests that effluent flow
limits be removed from our permit. We propose to sample during representative flows for all
other effluent limitations and monitoring requirements as they are now.
We have discussed this -issue with Mr. Terry Gross, the regional water treatment plant expert for
NCDENR/DEH — Public Water Supply Section. Mr. Gross indicated his support of this request.
We have also discussed flow issues with Mr. Rex Gleason with the Moresville Regional Office.
He stated no objections and deferred us to your office for approval.
Sludge Management Plan
The settling basins have not required removal of the settled solids as of yet. We do anticipate
this to become a necessity within the next 1-1/2 years. Our sludge management plan for the

settling basins is to contract dewater and haul the sludge. The sludge will be dewatered onsite
then hauled to BFI's landfill within the City limits of Concord. The City has a contract with BFI
for municipal solid waste disposal. The sludge if not landfilled by BFI will be mixed with soil
and used as daily cover for the landfill. We have already spoken with several firms for the
dewatering and hauling contract.
We look forward to your timely review and approval. Should you have need for additional
information, please do not hesitate to contact my office at [phone], ext. 303.

Dear Permittee:
The subject permit expires on September 30, 1999. North Carolina General Stature 143.215.1(c) requires that an
application for permit renewal be filed at least 180 days prior to the expiration date.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than April 3,
1999. Failure to request "renewal by April 3, 1999 will result in a civil' assessment of at least $250.'00. Larger
penalties may be assessed depending upon the delinquency -of the request.
If any wastewater discharge will occur after September 30, 1999 (or if continuation of the permit is desired), the
permit must not be allowed to expire.. Operation of waste treatment works or continuation of a discharge after
September 30, 1999 would violate NCGS 143-215.1- and could result in assessment of civil penalties of up to $10,000
per day.
If all wastewater discharge has ceased at. the subject facility, and you wish to rescind this permit, contact Robert
Farmer of the Division's Compliance. Enforcement Unit at (919) 733=5083, extension 531. You may also contact the

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Auk
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Environment, Health and
Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33
USC 1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as 'Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, -divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The, "maximum daily concentration" is the concentration of a pollutant discharge during a.
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal, to the concentration of a
composite sample or in the case of grab samples is the arithmetic'mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative. of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to the rate of flow measured at the time of
individual sample collection, or.
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point. Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However, in no case may the time interval
between effluent grab samples be greater than six (6) hours nor the number of samples less
than four (4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of
the individual values where N is equal to the number of individual values. The geometric
mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual
values. For purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weighted by. flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, any consecutive 24-hour period that reasonably
represents the calendar day may be used for sampling.
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to

periods of equipment, downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive. maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. upsets
a. Definition.
"Upset " means an exceptional incident in which there _is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating. logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b). (B) .of this
permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this

control of wastewaters shall be utilized/disposed of in accordance with NCGS .143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State
or navigable waters of the United States. The permittee shall comply with all existing federal

Part 11
Page 10 of 14
regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503,
any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be
reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40
CFR Part 503. The permittee shall comply with applicable 40 CFR Part 503 Standards for the
Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the
regulation, even if the permit is not modified to incorporate the requirement. The permittee
shall notify the Permit Issuing Authority of any significant change in its sludge use or disposal
practices.

DESCRIPTION OF PROPOSED WATER TREATMENT PLANT
The proposed Coddle Creek Water Treatment Plant is designed for a rated
production capacity of 12 million gallons per day of drinking water, to
be supplied to Cabarrus County and the City of Concord. The plant will
be located in Cabarrus County on the east side of Coddle Creek,
approximately 800 feet south of NC 73, downstream of the Coddle Creek
reservoir,.and will be owned and operated by the City of Concord. -
The discharge for which an NPDES permit is requested is the effluent
from the two proposed washwater lagoons on the site. The discharge
location is approximately 2,200 feet downstream of NC 73 on Coddle
Creek, as shown on the USGS quadrangle based vicinity map.
Estimates of drinking water production and treated washwater discharge
to Coddle Creek are tabulated below:

Daily Average; 6 mgd 0.3 mgd
Daily.Maximum: 9 mgd 0.45 mgd
1Source: "Engineer's Report for the Coddle Creek Water Treatment
Plant," Black & Veatch, November 1992: Coddle Creek production
assumed to be z of total service area demand, as projected for
the year 2000.
2Discharge water assumed to be 5% of production water.
The source of water for this facility is the Coddle Creek Reservoir.
As a provision of the reservoir construction, a minimum release rate of
6 cfs to Coddle Creek will be maintained. This minimum stream flow
will not be affected by the operation of the WTP.
The process to be used to treat water at this facility includes rapid
mixing, flocculation/clarification in contact adsorption clarifier
(CAC) treatment units, filtration in mixed media filters, and

disinfection. The chemicals that may be added to the water during
processing include powdered activated carbon (PAC), potassium
permanganate, alum, SELfloc 1823 (coagulant aid polymer), Nalco 8768
(coagulant), Magnifloc 985N (filter aid polymer), caustic soda,
polyphosphate, fluosilicic acid, and chlorine. See the attached site
plan and .plant process diagram for more information.
SOURCES OF WATER TO BE DISCHARGED
The primary sources of water .that w ill be stored in the lagoons and
discharged to Coddle Creek are the flushing of the CAC units and
backwashing of the filters. The CAC units are upflow clarifiers that
remove solids by adsorption to the media. The media type may be either
a buoyant plastic media held in place by a screen, or a coarse garnet
material. Solids are removed from these units by continuing the flow
of water through the units and applying an air scour to the flow of
water. Solids are removed from the filters.by backwashing, and surface
wash capability is also provided. The washwater and solids wasted from
the CAC units and filters are to be sent to the washwater lagoons for
treatment.
Water from the plant's process sump will also be delivered to the
lagoons. The process sump will collect the drains from the areas where
the plant process chemicals are loaded and stored, and from the floor
drains from. some of the buildings and structures on site. In addition,
sinks and drains in the laboratory will be directed to the sump.
Substances used in the laboratory may include acids and bases, along
with customary laboratory cleansers. The water collected in the sump
will be tested for suitability for discharging to the lagoons before
being pumped. In addition, laboratory procedures will be established
such that any organics or other substances not suitable to be
discharged to the lagoons will be contained and disposed of separately.
Other sources of water to the lagoons include the overflow piping from
the washwater and finished water reservoirs, and stormwater runoff.
The lagoon outlets will be designed with adequate capacity to carry
runoff from a 1007year storm, combined with plant process water, to the
discharge point to Coddle Creek. The lagoon effluent will be monitored
and sampled as required at a vault located on the discharge pipe.
TREATMENT OF PROCESS WASHWATER
Prior to discharging water back to Coddle Creek, treatment will be
provided in two washwater storage lagoons located on the site. The
water to be discharged will be stored in the lagoons, where solids will

be allowed to settle out. A number of fixed weir outlet structures
will be provided in each pond for the discharge of settled wastewater.
The settled water will flow over the weirs into collection piping that
will direct the flow by gravity to a single discharge point to Coddle
Creek.
The two lagoons may be used alternately over extended periods or used
in series to treat the water. The lagoons are sized to provide an
estimated 6 to 7 years of solids storage capacity, based on anticipated
solids wastage rates from the Coddle Creek plant. When the capacity of
one lagoon has been reached, it will be taken off line; drained, and
the sludge removed and disposed of. The remaining lagoon will be kept
on line during cleanout operations. Gravel access roads will be
provided to the lagoons, with ramps leading to the lagoon bottoms to
facilitate cleanout.
DISCUSSION OF ALTERNATIVES TO DISCHARGE
Four alternatives for managing process wastewater are listed below:
• Do not build Water Treatment Plant.
• Discharge process wastewater to sewer, with ultimate
treatment provided at wastewater treatment plant..
• Recycle wastewater to head of water treatment plant and mix
with influent raw water.
• Treat wastewater on site and discharge back to Coddle Creek.
The "no -build" alternative is unacceptable. Currently, the Hillgrove
WTP supplies drinking water for the City of Concord and portions of
Cabarrus County. This plant is already operating at capacity during
summer months, and additional water supply is needed. The Coddle Creek
Reservoir is already under construction, and water from this reservoir
is needed to augment the current water supply. For the Hillgrove WTP
to continue to be the only source for treating water for the county
would require significant distribution system improvements, as well as
expansion of the Hillgrove plant. It is more cost effective to build
the Coddle Creek WTP as proposed, and this will more efficiently
provide water to the service area in the vicinity of the reservoir.
Discharging wastewater to the sewer and treating it at the wastewater
treatment plant is not feasible because no sewer lines exist near the
Coddle Creek WTP site.. This alternative would require the construction
of additional sanitary sewer force mains and a pump station to deliver

MEMORANDUM Page 4

the wastewater to the sewer system. For this same reason, sewage
treatment for the WTP will be provided by an on site septic tank and
leachate field.
Recycling the wastewater back to the head of the plant and treating it
along with the raw water is undesirable because it reduces the overall
quality of the water to be treated and may make treatment more costly
or less effective. The Environmental Health Division of the State
Department of Environment, Health, and Natural Resources strongly
discourages recycling backwash water in water treatment plants.
The remaining -alternative is the proposed plan of treating the
wastewater in lagoons on site before discharging back to Coddle Creek.
This plan should provide acceptable water quality in Coddle Creek
downstream of the proposed water treatment plant, and is the most
acceptable solution for handling the wastewater from the treatment
process.

a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by. the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported This limitation is defined as "Annual Average" in Part I of the permit.

-a. The "average monthly, concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges , are sampled and measured, divided by the number of -daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar. day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily'concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow 'value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average under "Other Limits" in
Part I of the_permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or -in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal .coliform bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen'sample is taken over a calendar day, the
sample is considered to be the "'daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January.. through
March, April through June, July through September, and October through December.

Part Il
Page 3 of 14
a.. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow,.
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to- the rate of flow measured at the time of
individual sample collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point: Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly. spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However, in no case may the time interval
between effluent grab samples be greater. than six (6) hours nor the number of samples less
than four (4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The 'arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of
the individual values where N is equal to the number of individual values. The geometric
mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual
,values. For purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part 11
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, any consecutive 24=hour period that reasonably
represents the calendar day may be used for sampling.

A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.

Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the
facility by the Certification Commission, the permittee shall employ a certified wastewater
treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities.
Such operator must hold a certification of the grade equivalent to or greater than the
classification assigned to the wastewater treatment facilities by the Certification Commission.
The permittee must also employ a certified back-up operator of the appropriate type and any
grade to comply with the. conditions of Title 15A, Chapter 8A .0202. The ORC of .the facility
must visit each Class I facility at least weekly and each Class II, III, and IV facility at least
daily, excluding weekends and holidays, and must properly manage and document daily
operation and maintenance of the facility and must comply with all other conditions of Title
15A, Chapter 8A .0202. Once the facility is classified, the permittee shall submit a letter to the
Certification Commission which designates the operator in responsible charge within thirty
days after the wastewater treatment facilities are 50% complete.

Part II
Page 8 of 14
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This
provision requires the operation of back-up or auxiliary facilities or similar systems which are
installed by a permittee only when the operation is necessary to achieve compliance with the
conditions of the permit.
It shall not be a defense for a permittee in an enforcement action that it would -,have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this permit.
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical. damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded,, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of 'the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
. required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass wasunavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, .such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

Part 11

periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment -to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly. designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this
permit.
(4) The permittee complied with any remedial measures required under Part H, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset
has the burden of proof.
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State
or navigable waters of the United States. The permittee shall comply with all existing federal

- proposed-storage/settling lagoons that will ultimately discharge
to Coddle Creek.
The proposed point of discharge as submitted on the original
application has been modified to minimize on -site wetland impacts
during the construction of the outfall line. The new site is
approx. 100 yards upstream of the point designated on the
original application. A revised map will be submitted by the
applicant that reflects the revised discharge point.
Pending receipt of the revised WLA, additional WWT
facilities may be necessary to reduce constituents that may be
expected in discharges of this type. Therefore, pending approval
of the WLA, it is,recommended that NPDES Permit be issued.

Coddle Creek Water Treatment Plant
NPDES Discharge Permit Application

From: D. M. Parker
DESCRIPTION OF PROPOSED WATER TREATMENT PLANT
B&V Project 19807.105
B&V File A
December 23, 1992
The proposed Coddle Creek Water Treatment Plant is designed for a rated
production capacity of 12 million gallons per day of drinking water, to
be supplied to Cabarrus County and the City of Concord. The plant will
be located in Cabarrus County on the east side of Coddle Creek,
approximately 800 feet south of NC 73, downstream of the Coddle Creek
reservoir, and will be owned and operated by the City of Concord.
The discharge for which an NPDES permit is requested is the effluent
from the two proposed washwater lagoons on the site. The discharge
location is approximately 2,200 feet downstream of NC 73 on Coddle
Creek, as shown on the USGS quadrangle based vicinity map.
Estimates of drinking water production and treated washwater discharge
to Coddle Creek are tabulated below:
Drinking Water Discharge to
Production) Coddle Creek
WTP Rated Capacity: 12 mgd 0.6 mgd
Daily Average: 6 mgd 0.3 mgd
Daily Maximum: 9 mgd 0.45 mgd
1Source: "Engineer's Report for the Coddle Creek Water Treatment
Plant," Black & Veatch, November 1992. Coddle Creek production
assumed to be 2 of total service area demand, as projected for
the year 2000.
ZDischarge water assumed to be 5% of production water.
The source of water for this facility is the Coddle Creek Reservoir.
As a provision of the reservoir construction, a minimum release rate of
6 cfs to Coddle Creek will be maintained. This minimum stream flow
will not be affected by the operation of the WTP.
The process to be used to treat water at this facility includes rapid
mixing, flocculation/clarification in contact adsorption clarifier
(CAC) treatment units, filtration in mixed media filters, and

disinfection. The chemicals that may be added to the water during
processing include powdered activated carbon (PAC), potassium
permanganate, alum, SELfloc 1823 (coagulant aid polymer), Nalco 8768
(coagulant), Magnifloc 985N (filter aid polymer), caustic soda,
polyphosphate, fluosilicic acid, and chlorine. See the attached site
plan and plant process diagram for more information.
SOURCES OF WATER TO BE DISCHARGED
The primary sources of water that will be stored in the lagoons and
discharged to Coddle Creek are the flushing of the CAC units and
backwashing of the filters. The CAC units are upflow clarifiers that
remove solids by adsorption to the media. The media type may be either
a buoyant plastic media held in place by a screen, or a coarse garnet
material. Solids are removed from these units by continuing the flow
of water through the units and applying an air scour to the flow of
water. Solids are removed from the filters by backwashing, and surface
wash capability is also provided. The washwater and solids wasted from
the CAC units and filters are to be sent to the washwater lagoons for
treatment.
Water from the plant's process sump will also be delivered to the
lagoons. The process sump will collect the drains from the areas where
the plant process chemicals are loaded and stored, and from the floor
drains from some of the buildings and structures on site. In addition,
sinks and drains in the laboratory will be directed to the sump.
Substances used in the laboratory may include acids and bases, along
with customary laboratory cleansers. The water collected in the sump
will be tested for suitability for discharging to the lagoons before
being pumped. In addition, laboratory procedures will be established
such that any organics or other substances not suitable to be
discharged to the lagoons will be contained and disposed of separately.
Other sources of water to the lagoons include the overflow piping from
the washwater and finished water reservoirs, and stormwater runoff.
The lagoon outlets will be designed with adequate capacity to carry
runoff from a 100-year storm, combined with plant process water, to the
discharge point to Coddle Creek. The lagoon effluent will be monitored
and sampled as required at a vault located on the discharge pipe.
TREATMENT OF PROCESS WASHWATER
Prior to discharging water back to Coddle Creek, treatment will be
provided in two washwater storage lagoons located on the site. The
water to be discharged will be stored in the lagoons, where solids will

be allowed to settle out. A number of fixed weir outlet structures
will be provided in each pond for the discharge of settled wastewater.
The settled water will flow over the weirs into collection piping that
will direct the -flow by gravity to a single discharge point to Coddle
Creek.
The two lagoons may be used alternately over extended periods or used
in series to treat the water. The lagoons are sized to provide an
estimated 6 to 7 years of solids storage capacity, based on anticipated
solids wastage rates from the Coddle Creek plant. When the capacity of
one lagoon has been reached, it will be taken off line, drained, and
the sludge removed and disposed of. The remaining lagoon will be kept
on line during cleanout operations. Gravel access roads will be
provided to the lagoons, with ramps leading to the lagoon bottoms to
facilitate cleanout.
DISCUSSION OF ALTERNATIVES TO DISCHARGE
Four alternatives formanaging process wastewater are listed below:,
• Do not build Water Treatment Plant.
• Discharge process wastewater to sewer, with ultimate
treatment provided at wastewater treatment plant.
• Recycle wastewater to head of water treatment plant and mix
with influent.raw water.
• Treat wastewater on site and discharge back to Coddle Creek.
The "no -build" alternative is unacceptable. Currently, the Hillgrove
WTP supplies drinking water for the City of Concord and portions of
Cabarrus County. This plant is already operating at capacity during
summer months, and additional water supply is needed. The Coddle Creek
Reservoir is already under construction, and water from this reservoir
is needed to augment the current water supply. For the Hillgrove WTP
to continue to be the only source for treating water for the county
would require -significant distribution system improvements, as well as
expansion of the Hillgrove plant. It is more cost effective to build
the Coddle Creek WTP as proposed, and this will more efficiently
provide water to the service area in the vicinity of the reservoir.
Discharging wastewater to the sewer and treating it at the wastewater
treatment plant is not feasible because no sewer lines exist near the
Coddle Creek WTP site. This alternative would require the construction
of additional sanitary sewer force mains and a pump station to deliver

MEMORANDUM Page 4
Concord, North Carolina B&V Project 19807.105

NPDES Discharge Permit Application
Attachment to Short Form C
the wastewater to the sewer system. For this same reason, sewage
treatment for the WTP will be provided by an on site septic tank and
leachate field.
Recycling the wastewater back to the head of the plant and treating it
along with the raw water is undesirable because it reduces the overall
quality of the water to be treated and may make treatment more costly
or less effective. The Environmental Health Division of the State
Department of Environment, Health, and Natural Resources strongly
discourages recycling backwash water in water treatment plants.
The remaining alternative is the proposed plan of treating the
wastewater in lagoons on site before discharging back to Coddle Creek.
This plan should provide acceptable water quality in Coddle Creek
downstream of the proposed water treatment plant, and is the most
acceptable solution for handling the wastewater from the treatment
process.

Dear Mr. Scheller:
As we discussed on the telephone, I am attaching a copy of October's eDMR, a copy of the Chain of Custody for -the samples that Pace Laboratories analyzed, and
a copy of the email that Taylor Ezell of Pace sent me, stating that due to their error, they did not analyze the sample for TKN. As you will recall, Pace eventually
analyzed the sample for TKN, but it was after it had exceeded its hold time. You will see that I noted this in the comments section of the report. Thank you for
your assistance with this matter. Please feel free to contact me at this email or by telephone at [phone], if you have any questions, or if there is -anything
else I need to provide.
Sincerely,
Jeff Isley

Subject: Total Nitrogen
Importance: High
Jeff, I've tried to track this down for you, but you were right, we didn't run it. I can see where the analysis was logged in
but it looks like it was canceled inadvertently by the lab. I apologize for the error.
We should still have this sample if you want us to run the TKN and calculation now. However, it will be flagged as out of
hold. I can do this at no charge. I'm not sure if the state would rather see no data or out of hold data.
Again, I apologize for the error. Please let me know how you would like to proceed.

Dear Mr. Scheller:
As I was working on the October, 2017 eDMR for the Coddle Creek WTP lagoon system (NC0083119) today, I noticed
that neither the total nitrogen result nor the TKN result were shown on the report provided to me by the contract lab
that analyzes most of our wastewater analyses (PACE Labs). However, the lab did analyze the nitrate / nitrite part of the
Total N. I called our PACE contact person, Taylor Ezell, and asked him about this. Mr. Ezell said he would look into it. A
few hours later Mr Ezell sent me an email (see attachment) that stated that the sample was logged in, butinadvertently
canceled by their lab. Mr Ezell offered to analyze the sample now and flag it as being out of hold time. I called Mr. Wes
Bell and explained the situation to him, and he asked me to send you this email, and to do the following:
1) Have PACE Labs analyze the TKN sample and do the Total Nitrogen calculation.
2) On the .eDMR, check "compliant," but under the comments section, note that the Total N result is qualified, due
to the TKN sample being outside of its hold time.
3) Attach copies of the Chain of Custody (COC, also attached with this email) and Mr. Ezell's email to both printed
copies of the eDMR, which you will receive in the mail, 'as usual.
Also, Mr. Bell requested me to provide you with corrective actions, so that this issue does not occur again. To that end,
from now on I will contact the contract lab within 2 weeks after we have collected and sent them samples, to obtain
results and make sure everything is correct. Additionally, whenever possible, I will schedule sample days at the
beginning of the month, so that there will be time to resample, if a problem such as this one occurs.
Thank you for your assistance with this matter. Feel free to contact meat this email or by telephone, at [phone],
if you have any questions or if there is anything else I need to do.
Sincerely,
Jeff Isley

Jeff, I've tried to track this down for you, but you were right, we didn't run it. I can see where the analysis was logged in
but it looks like it was canceled inadvertently by the lab. I apologize for the error.
We should still have this sample if you want us to run the TKN and calculation now. However, it will be flagged as out of
hold. I can do this at no charge. I'm not sure if the state would rather see no data or out of hold data.
Again, I apologize for the error. Please let me know how you would like to proceed.

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

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 (NOls); Notices of Termination (NOTs)];
3. Pretreatment Program Reports; and
4. Sewer Overflow/Bypass Event Reports
EPA's web site will also link to the appropriate electronic reporting tool for each type of electronic
submission for each state. Instructions on how to access and use the appropriate electronic reporting
tool will be available as well.
For more information on EPA's NPDES Electronic Reporting Rule, visit
http://www2.epa.goy/compliance/final-national-pollutant-discharge-elimination-system-npdes-

I. INTRODUCTION:
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental. samples.
II. GENERAL COMMENTS:
The laboratory did an excellent job and no deficiencies were observed. In most cases laboratory
documentation meets or exceeds method and program requirements. The laboratory is commended for
its efforts and we appreciate their continuing cooperation.
III. DEFICIENCIES, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
A. COMMENT: The automatic temperature compensation (ATC) feature of the pH meter was not verified
on an annual basis.
REQUIREMENT: (New Policv) Automatic Temperature Compensator Check (ATC) for pH meter
and Conductivity meter: (Check every 12 months)
1. Take a buffer or standard solution and cool to below 10°C and read the temperature. Analyze, the
buffer or standard solution at that temperature. Document the temperature and the measured pH or
standard solution value obtained on the log sheet.
2. Raise the temperature of the buffer or standard solution to approximately 25°C. Document the
temperature and the measured pH or standard solution value on the log sheet.
3. Raise the temperature of the buffer or standard solution to approximately 35°C. Document the
temperature and the measured pH or standard solution value on the log sheet.
4. Repeat with additional temperature adjustments and pH or standard solution readings as necessary
to ensure the temperature usually measured for samples has been bracketed. As the temperature
increases or decreases the value of the buffer or standard solution should remain approximately the
same.
METALS:
B. COMMENT: The LCS (2"d source) is at the mid -range while the CCV (curve Check) is at or near the
reporting limit concentration.

Page 2
REQUIREMENT: While this procedure produces comparable results it does not meet the regulatory
requirement. The Continuing Calibration Verification (CCV) is made from the same standards used to
create the calibration curve. The CCV must be in the mid -range and agree .to at least ±10% of the true
value of the standard. The LCS (2Id source) standard may be at any range bracketed by the analytical
curve. Also the LCS acceptance criteria may be supplied by a vendor, generated by the laboratory, or set
by the laboratory and may have.a wider acceptance criteria range. Ref: 15A NCAC 2H .0805 (7) (I)
C. COMMENT: The laboratory documents standard and reagent prep for metals however purity
certificates are not organized so that they can be easily traced from standard prep.
REQUIREMENT: Where purity and assay documentation information is supplied it is considered required
supporting information. These documents must be organized and available for review upon request. Such
documentation must also be maintained for a period of five years. Ref: 15 A NCAC 2H .0805 (A) (7) and
(7) (A).
Note: The certificates. were available and.. it will be a simple matter to organize them chronologically in a
file or binder. The lotnumbers for the standards are documented on the metals worksheet so it will then
be a simple matter to match a certificate with a specific sample set.
IV. PAPER TRAIL INVESTIGATION:
No other laboratoryitems were observed as a result of data and DMR reviews.
V. CONCLUSIONS:
Correcting the above cited comments and implementing the recommendations will help this lab to
produce quality data and meet certification requirements. Please respond to all lettered comments.

Comment: Effluent waters flow though an open ditch on an adjacent property traversing some woods before reaching the

RECOMMENDATION: We recommend that the column headings

METALS:
e
B). COMMENT: Metals LCS (Laboratory Control Standards) are not digested as samples.
REQUIREMENT: This program considers the LCS a method quality control sample. The
purpose of the LCS is to evaluate the efficiency and performance of the entire procedure.
The LCS must therefore be treated in every aspect as a sample. The LCS-is some times
referred to as the LFB (Laboratory Fortified Blank) Standard Methods 20t' Edition 1020 B
states in part: Process the LFB through all of the sample preparation and analysis steps".
The general requirement for analysis of a second source standard is 15A NCAC 2H
.0805 (a) (7) (B) which states in part: "analyze one known standard in addition to
calibration standards each day samples are analyzed to document accuracy". The
laboratory may purchase a known LCS, or prepare a LCS using a standard from a
different vendor, or a different lot number from the same vendor.
DATA REVIEW:
General laboratory records and documentation was reviewed. Data and DMRs from
May, June and July 2003 were reviewed. No items other than those specified in the
above report were observed.
IV. CONCLUSION:
Correcting the above cited comments and implementing the recommendations will help
this lab to produce quality data and meet certification requirements. Please respond to
all lettered comments.

Coddle Creek Water Treatment Plant Laboratory
P.O. Box 308 Concord, NC 28026
Number: 569
Maintenance
September 11, 2003
Chet Whiting
Mr. Jeff Isley
The above named laboratory was inspected to verify compliance with 15A NCAC 2H .0800 for
the analysis of environmental samples.
II. OVERVIEW:
The laboratory was neat and well organized. Laboratory personnel provided the inspector(s) with
all materials, and information requested for examination. The Laboratory continues to do an
excellent job. Some minor adjustments are listed below.
III. DEFICIENCIES, REQUIREMENTS, COMMENTS, AND RECOMMENDATIONS:
GENERAL LABORAOTORY:
A). COMMENT: The laboratory needs additional documentation to increase tracking of
consumable laboratory materials such as pH buffers and solids filters.
RECOMMENDATION: Specific batches or lots of reagents and materials used for sample
analysis could conceivably- be questioned during a review process. Since the document
retention policy is five years. the practice of writing date received and opened on containers is no
longer practical. This item is easily resolved by adding information for the above to existing
receipt documentation. Simply add the item, vendor, lot number, date received and date put in
service (expiration date if applicable) to the current chemical receipt log. Ref: 15 A NCAC 2H
.0805 (7), (7) (A) & (G).
TURBIDITY:
RECOMMENDATION: Sample collection times and temperature information for stream turbidity

Subject: NPDES Permit Renewal Application
Permit NCO083119
Coddle Creek WWTP
Cabarrus County
The NPDES Unit received your permit renewal lapplication on June 26, 2003. Thank you for submitting
this package. The renewal request did not include a sludge management plan. Please submit a
sludge management plan.
The permit renewal for this facility will be assigned to Charles Weaver. This staff member will contact
you if further information is needed to complete the permit_ renewal. Please note that the NPDES Unit
has several vacant positions. This staff. shortage has lasted for over 4 years and is delaying all permit
renewals. Our remaining permit writers are currently reviewing Authorizations to Construct,
speculative limit requests, major permit modifications and 201 plan updates ahead of permit renewals.
This is necessary due to a variety of factors, including mandatory deadlines in the statutes which
govern our program.
If this staff shortage delays reissuance of NCO083119 the existing requirements in your permit will
remain in effect until the permit is renewed (or the Division takes other action). We appreciate your
patience and understanding while we operate with a severely depleted staff. If you have any
additional questions concerning renewal of the subject permit, please contact Charles Weaver at (919)
733-5083, extension 511.

is staffed with operators 24 hours per day, 7 days per week.
LABORATORY:
The on -site laboratory (Certificatio^. #569) performs all analyses (including field analyses). All
laboratory instrumentation appeared to be properly maintained and calibrated.
SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period of February 2002 through January 2003, inclusive_
No limit violations were reported. All monitoring frequencies and locations appeared correct. All
samples appeared to be properly preserved and meet the required holding times. On several occasions,
effluent parameters were analyzed without any documentation of on -site operators (on the DMR). The
facility staff indicated that the appropriate documentation would be immediately incorporated. Although
the upstream and downstream locations are compliant with the permit's requirements, this office
recommends (if feasible) the instream sampling be performed at a closer proximity to the discharge
location.
EFFLUENT/RECEIVING STREAM:
The effluent appeared clear with no floatable solids or foam_ The effluent flows in a stormwater
ditch/effluent channel for greater than 100 yards (from the outfall) prior to entering the receiving
stream_ The receiving stream was not evaluated.
FLOW MEASUREMENT:
The effluent is measured continuously by a broad crested V-notch weir and an ultrasonic flow meter with a
totalizer_ The flow meter was last calibrated by Johnston, Inc_ of Indian Trail, N.C. on 3/14/03. 'The
flow meter is calibrated on an annual basis.
This office recommends the installation of a sharp -crested V-notch weir (no greater than 1/4 inch in
thickness) for more accurate flow measurements. The width of the weir causes the water to back up (in
the channel) which elevates the actual head measurements and corresponding flow readings. In addition,
rocks/debris were observed in the flow measurement channel. If the rocks/debris are stationary without
any possibility of displacement; then the rocks may remain in the channel. I£ the rocks/debris are
removed and/or a sharp -crested V-notch weir is installed, then the flow measurement system should be
recalibrated.
SLUDGE DISPOSAL:
According to the WTP Superintendent, sludge was last removed from this facility three years ago.
Bio-nomics, Inc. utilized a temporary sludge press to dewater the sludge prior to removal and disposal by
Allied Waste, Inc. to the LMS Landfill in Harrisburg, N_C.

The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq.
Annual Average
The arithmetic mean of all "daily 'discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
B ass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which

consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling'
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1 /24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean,'values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 ml collected over a.period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
