STANDARD CONDITIONS FOR NPDES PERMIT S
SECTION A, DEFINITIONS
1, Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or. Division
Means the Division of Environmental Manageae.n, Department of Environment, Health
and Natural Resources.
3.
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.

Part 11
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 coliforrn 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 coliforrn 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.

g.
Part 11
Page 3 of 14
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 .Measurement
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 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.

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
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.
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.
11. Hazardous Substance
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.

Page 9 of 14
(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
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 deterrnines that it will meet the

5. Upset
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
irnproper operation.
b. Affect 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 (3) of this condition 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:
(a) An upset occurred and that the perrnittee can identify the cause(s) of the upset;
(b) The permittee facility was at the time being properly operated; and
(c) The penimittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of
this permit.
(d) The permittee complied with any remedial measures required under Part II, B. 2, of
this permit.
d. Burden of proof.
In any enforcementproceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.
