1. Permit Issuing Authoritv
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..
ss/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 w 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 II
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
nt
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 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 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.
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.

Part II
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 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.
". 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,
s of Samples
Composite Sample: A composite sample shall consist of:
(1) a series of grab sarnples 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 sarnple collection, or
(2) a series of grab samples o:f 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 analog 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

facilities. The permittee shall notify the Division's Operator Training and Certification Unit
within thirty days of any change in the ORC status.

Part II
Page 8 of 14
Proper Operation and Maintenance
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 backup or auxiliary facilities or
similar systems which are installed by a. perrrtittee only when the operation is necessary to
achieve compliance with the conditions of the permit.
3. Need to Halt a Reduce not a Defense
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.
4. Bypassing of Treatment Faciliti
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 was unavoidable to prevent loss of life, personal injury or severe
property damage;

Part II
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 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:
(a) An upset occurred and that the permittee can identify the cause(s) of the upset;
(b) The permittee facility was at the time being properly operated; and
(c) The permittee 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 enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.

Part II

6. RemovedSubstan
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be disposed of in accordance with NCGS 143-2151 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 pennittee 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 disposal of sludge
