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 rneasured, 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 1 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.

Part II
Page 2 of 14
oncent^ration. 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 coliformn 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.
g.
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 1 of the permit,
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
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 tame 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).
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.

4. Bypassing_ of Treatment pacil)ties
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,
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

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.
bEffect 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) (8) of this permit.
(4) The permittee complied with any remedial measures required under Part II, B, 2. of this
permit.

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 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 Perrnit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. a Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation,
Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the
discharge of untreated or inadequately treated wastes during electrical power failures either by
means of alternate power sources, standby generators or retention of inadequately treated effluent.

The deficiencies noted in your Compliance Evaluation Inspection Reports
conducted on Feburary 11, 1999 by Linda Love of your office have been studied and will
be addressed in the following manner at each WWTP listed above.
LABORATORY
1 The pH and Total Residual Chlorine meters will be calibrated before use and proper
calibration maintained. Calibration information such as, but not lirnited to, date, time,
name of analyst calibrating meter, and standards used for calibrating will be recorded.
2. The Total Residual Chlorine meter will be calibrated with three standards (low range,
mid range, high range) each day the meter is used; or with one mid -range standard each
day the meter is used, and a range of five standards analyzed on an annual basis,
3 Documentation of the internal curve verification and daily standard check will be
maintained.
The above procedures have been studied carefully with our new ORC and should not be a
problem in the future.
SELF -MONITORING PROGRAM
In December of 1998, we hired a new ORC. He had not completed a monthly
monitoring report for some time and failed to complete the December report correctly, An
amended report for that month has been submitted.
Failure to monitor items in December 1998 have been adressed with the ORC and he is
now aware of the frequency of items to be monitored, We have brought in representatives

from our private laboratory to work with our ORC on the incorrect monitoring and
reporting. Linda Love of your office was also very helpful.
In the fumre, all monitoring in addition to the required ount will be reported on the
monthly

Subject: Renewal of NPDES Permit NC0037389
West Iredell High School
Iredell County
The subject permit expires on July 31, 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 February 1,
1999. Failure to request renewal by February 1, 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 July 31, 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 July 31, 1999
would violate NCGS 143-215.1 and could result in assessment of civil penalties of up to $10,006 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 [phone], extension 531. You may also contact the
Mooresville Regional Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items which you must
submit when applying for renewal of the subject permit.
If you have any questions, please contact me. My telephone number, fax number and a - mail address are listed below.

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 Pan 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
arc 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 arc 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.

Part ll

b. Concentration Measuremeat
a. The "average monthly concentration," other than for fecal col fcr ri bacteria, is the sum of
the concentrations of all daily discharges sarnpl+dd for measured during a calendar month
on which daily discharges are sampled and ne ured, 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 focal 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 surn 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.
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 1 of the permit.
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. Row, (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. TypsofSa1T1p1es
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 sarnpling 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 (I).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weightcd 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.

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

SECTION E. REPORTINQ REOUIREMENTS
1. Change in Discharge
All discharges authorized herein shall be consistent with the terms and conditions of this
permit. The discharge of any pollutant identified in this permit more frequently than or at a
level in excess of that authorized shall constitute a violation of the permit.
2. Planned Changes
The permittee shall give notice to the Director as soon as possible of any planned physical
alterations or additions to the permitted facility. Notice is required only when:
a. The alteration or addition to a permitted facility may meet one of the criteria for determining
whether a facility is a new source in 40 CFR Part 122.29 (b); or
b. The alteration or addition could significantly change the nature or increase the quantity of
pollutants discharged. This notification applies to pollutants which are subject neither to
effluent limitations in the permit, nor to notification requirements under 40 CFR Part 122.42
(a) (1).
c. The alteration or addition results in a significant change in the permirtee's sludge use or
disposal practices, and such alternation, addition or change may justify the application of
permit conditions that are different from or absent in the existing permit, including
notification of additional use or disposal sites not reported during the permit application
process or not reported pursuant to an approved land application plan.
3 . Anticipated Noncompliance
The rermittee shall give advance notice to the Director of any planned changes in the permitted
facility or activity which may result in noncompliance with permit requirements.

Part II

4. Act or "Jhe Act"
The Federal Water Pollution ntrol. 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 duringthe 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.

Part ll
Page 2 of 14
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 sure
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 Units" 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 Units" 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 Units" in Part I of the permit
d. The "average annual concentration," other than for fecal conform 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.
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 L

Part II
Page 3 of 14
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 riods: 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:
(I) 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.
9. Calculation of Mears
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.

Part II
Page 4 of 14
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

review of records revealed that the SOC may no longer be necessary.
The SOC was issued on. December 14, 1990 and expires on December
15, 1994. The facility is currently in compliance with the final
effluent limits for BOD and TSS set forth in the existing Permit.
On -site inspection indicated that the facility appeared to
be in good operational condition and properly maintained. It is
recommended that the subject Permit be renewed as requested by
the applicant.

PART V EVALUATION AND RECOMMENDATIONS
is
pals
The wastewater treatment plant was not in good operational condition during
the site investigation. The aeration basin was light grey in color which indicated
a poor MLSS. A substantial amount of turbulence was observed in the clarifier.
A broken transfer line or a hole in the wall separating the two basins is a
possibility. Little or no sludge return was evident from the clarifier. A large
amount of scum and other solid material was evident on the surface of the clarifier,
which indicated problems with the scum return. Solids have settled in the post
aeration chamber and have gone septic. Chlorine tablets were evident in the
chlorinator.
This wastewater treatment plant is currently serving a student population of
approximately 750-800 students.
It is recommended that the NPDES Permit for this facility be renewed.

completed a preliminary engineering review of the subject
be addressed before we can cotntalete our review:
1) A sludge management plan must be submitted for the final disposal of residual solids
generated by the proposed wastewater treatment facThe use of a septage hauler to
a Division of Environmental Health land application site is not acceptable. The sludge
must be transported to a municipal wastewater treatment facility or a Division of
Environmental Management (D.E.M.) approved land. application site. If the sludge is
to be taken to a municipal wastewater treatment facility then please provide a letter from
the municipality agreeing to accept the sludge, if the sludge is to be taken to a D.E.M.
approved land application site then a letter from the land application site Permittee
agreeing to accept the sludge must be provided. In addition, the land application site
Permittee must apply for modification of his permit to allow this source to be added.
Please be advised that if the sludge is to he land applied it must be stabilized by a

While reviewing the application package it became apparent that renewal of the NPDES permit had
been requested. Please be advised that if the discharge point of the subject wastewater treatment facility is
into a zero flow stream (i.e.,7Q10 = 0 & 30Q2 = 0), then the NPDES permit may receive limits of BOD5
5 mg/1 and NH3 = 1 upon reissuance; however, if the stream shows a positive 30Q2 flow then the
NPDES Permit may receive a toxicity limitation and/or a NH3 lirnit upon permit reissuance. It is important
for lredell-Statesville Schools to explore the flow in the receiving stream to determine if the proposed
wastewater tre.a.trnent facility would need to be redesigned to r.eet more stringent effluent limitations.
Refer to the subject permit application number when providing the requested information. Please
submit four copies of all information to my attention at the address below. Also, please
note that failure to provide this additional information on or before February 1.5, 1.992 will subject your
application to being returned as incomplete., in accordance with 1.5A NCAC 211 .0208.

IREDELL
Our files indicate that the subject permit for a wastewater
discharge to the surface water expires on 870531. G% 143-215.i(c)
requires that an application for renewal must be filed 188 days prior to
the expiration date. We have not received an application for renewal
from you as of this date.
If there is no change proposed for the discharge, the application
needs only to consist of a letter requesting renewal and the
application processing fee. (See attached.) Dischargers which
propose a change, major industrial dischargers and all municipal
dischargers are required to submit a new application form when
they request renewal. If this is a major industrial or municipal
discharge, an application is attached for your use.
This matter should be given prompt attention in that continued
discharge after the permit's expiration, without the filing of a
complete and timely application for renewal, constitutes discharge
without a permit and is a violation of GS 143-215.i(e) and the
Federal Clean Water Act of 1977. Application for renewal should be
submitted to:

In accordance with the provisions of Article 3, Section 90A - 37 of the
General Statutes of North Carolina the Wastewater Treatment Plant Operators
Certification Commission hereby classifies the above name plant as a
Class j Facility, which requires you to take appropriate steps to
designate an operator in responsible charge, who is properly certified to
operate the facility.
To assist you in designating an operator to be in responsible chargeof
your facility, we are attaching copies of the following, documents for your
use:
1. Excerpt of the Certification Commission's Regulation,
which sets forth the requirement for Certified Operators.
2. Postal Card to be used in designating the operator in
responsible charge. Please complete and return to this office
as soon as possible.
. Application For Certification to be used in obtaining active
Certification in event the operator designated by you to be
the operator in responsible charge does not hold a valid
certificate in the same grade as the classification of the
treatment facility.

For your information, the requirement for a Certified Operator is
applicable at the time existing, wastewater treatment facilities are
classified, and for new wastewater treatment facilities, by the time the
construction of the facilities are 50% completed. The latter is to enable
the operator to become familiar with the plant layout, piping, underground
utilities, and the checkout of all equipment.
You are urged to take the necessary steps in accordance with the
provisions of Article 3 Chapter 90A of the General Statutes of North Carolina
to designate an operator to be in responsible charge of your facility, and
have him properly certified. If we can be of assistance in this matter,
please advise.
Sincerely yours,

(27) Sludge Gas Utilization - The process of using sewage gas for the purpose
of heating buildings, driving engines, etc.
(28) Sludge Incinerators - A furnace designed to burn sludge and to remove all
moisture and combustible material and reduce the sludge to a sterile ash.
(29) Sludge Thickener - A type of sedimentation tank in which the sludge is
permitted to settle and thicken through agitation and gravity.
(30) Stabilization Lagoon - A type of oxidation lagoon in which biological
oxidation of organic matter is effected by natural or artificially
accelerated transfer of oxygen to the water from air. (Not a polishing pond)
(31) Stand-by Power Supply - On site or portable electrical generating equipment.
(32) Tertiary Treatment - A stage of treatment following secondary which is
primarily for the purpose of effluent polishing. A settling lagoon or sand
or coal filter might be employed for this purpose.
(33) Toxic Materials - "Toxic Materials" means those wastes or combinations of
wastes, including disease-caueing agents which after discharge and upon
exposure, ingestion, inhalation or assimilation into any organism, either
directly from the environment or indirectly by ingestion through food
chains, will cause death, disease, behavioral abnormalities, cancer, genetic
mutations, physiological malfunctions (including malfunctions in reproduc-
tion), or physical deformations, in such organisms or their off -spring.
Toxic materials include, by way of illustration and not limitation: Lead,
cadmium, chromium, mercury, vanadium, arsenic, zinc, ortho-nitro-chloroben-
zene (ONCB), polychlorinated biphenyls (PCB's) and dichlorpdiphenyl
trichloroethane (DDT); and any other materials that have or may hereafter
be determined to have toxic properties.
(34) Trickling Filter - A biological treatment unit consisting, of a material
such as broken stone or rock over which wastewater is distributed. A high
rate trickling filter is one which is operated at between 10 and 30 mgd per
acre, A low rate trickling filter is one which is aesigned to operate at
1 to 4 mgd per acre.
(35) Thermal Pollution Control Device - A device providing for the transfer of
heat from a fluid flowing in tubes to another fluid outside the tubes,
or vice versa; or, other means of regulating liquid temperatures.
(36) Vacuum Filters - Centrifuges cr Filter Presses - Devices which are designed
to remove excess water from either digested or undigested sludge prior to
disposal or further treatment.
