Our records indicate that NPDES Permit No. NC0025861 was
issued on September 4, 1996 for the discharge of wastewater to the
surface waters of the State from your facility. The purpose of
this letter is to advise you of the importance of the Permit and
the liabilities in the event of failure to comply with the terms
and conditions of the Permit. If you have not already done so, it
is suggested that you thoroughly read the Permit. Of particular
importance is Page 4 .
Page 4 sets forth the effluent limitations and monitoring
requirements for your discharge. Your discharge must not exceed
any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types
and sampling locations. Upon commencement of your discharge (or
operation) , you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or
approved by this Agency. If you have not received these forms,
they should be arriving shortly. If you fail to receive the forms,
please contact this Office as quickly as possible. I have enclosed
a sample of the "Effluent" reporting form (DEM Form MR-1) , plus
instructions for completing the form. It is imperative that all
applicable parts be completed, and the original and one copy be
submitted as required.
Please be advised that an annual administering and compliance
monitoring fee may be required for your facility. You will soon be
receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent
enforcement action or possible revocation of your permit.
The remaining Parts of the Permit set forth definitions,
general conditions and special conditions applicable to the
operation of wastewater treatment facilities and/or discharge(s) .

The conditions include special reporting requirements in the event
of noncompliance, bypasses, treatment unit/process failures, etc.
Also addressed are requirements for a certified wastewater
treatment plant operator if you-are operating wastewater treatment
facilities. Any changes in operation of wastewater treatment
facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment
facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215. 6 of the North Carolina General Statutes. A civil
penalty of up to $10,000 per violation (and/or criminal penalties)
may be assessed for such violations. If you find at any time that
you are unable to comply with the terms and conditions of the
Permit, you should contact this Office immediately. A Consent
Order may be necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a
five-year period. Permits are not automatically renewed. Renewal
requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of
your Permit. This date is set forth on Page 1 of the Permit. Also
note that NPDES Permits are not automatically transferable. If
you, as the Permittee, cease to need this Permit, then you should
request that the Permit be rescinded or transferred to another
party, if necessary.
As mentioned previously, the purpose of this letter is to
advise you of the importance of your NPDES Permit. Please read the
Permit and contact this Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to
providing any assistance.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or"the Division"
Means the Division of Water Quality, 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.

Part II
Page 2 of 14
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.

Part II
Page 3 of 14
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).
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.

Part II
Page 4 of 14
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.

Part II
Page 8 of 14
3. Need to Halt or 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 Facilities
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;
(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.

Part II

5. sets
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
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
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 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.
7. 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.

Raleigh, N.C. 27607
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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

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.

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
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.

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

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.
SECTION B. GENERAL CONDITIONS
1. Duly to Comply
The permittee must comply with all conditions of this permit. Any permit noncompliance
constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit
termination, revocation and reissuance, or modification; or denial of a permit renewal
application.
a. The permittee shall comply with effluent standards or prohibitions established under
section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage
sludge use or disposal established under section 405(d) of the Clean Water Act within the
time provided in the regulations that establish these standards or prohibitions or standards
for sewage sludge use or disposal, even if the permit has not yet been modified to
incorporate the requirement.
b. The Clean Water Act provides that any person who violates a permit condition is subject to
a civil penalty not to exceed $25,000 per day for each violation. Any person who
negligently violates any permit condition is subject to criminal penalties of $2,500 to
$25,000 per day of violation, or imprisonment for not more than 1 year, or both. Any
person who knowingly violates permit conditions is subject to criminal penalties of$5,000
to$50,000 per day of violation,or imprisonment for not more than 3 years,or both. Also,
any person who violates a permit condition may be assessed an administrative penalty not
to exceed $10,000 per violation with the maximum amount not to exceed$125,000. [Ref:
Section 309 of the Federal Act 33 U.S.C. 1319 and 40 CFR 122.41 (a)]
c. Under state law, a civil penalty of not more than ten thousand dollars ($10,000) per

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).

• 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
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset
has the burden of proof.
6. Removed Substances
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

Management,conduct groundwater monitoring as may be required to determine the compliance
of this NPDES permitted facility with the current groundwater standards.
D. Publicly Owned Treatment Works
All POTWs must provide adequate notice to the Director of the following:
1. Any new introduction of pollutants into the POTW from an indirect discharger which
would be subject to section 301 or 306 of CWA if it were directly discharging those
pollutants; and
2. Any substantial change in the volume or character of pollutants being introduced into that
POTW by a source introducing pollutants into the POTW at the time of issuance of the
permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality
and quantity of effluent introduced into the POTW, and (2) any anticipated impact of the
change on the quantity or quality of effluent to be discharged from the POTW.

Part III Permit No. NC0025861
E. ACUTE TOXICITY PERMIT LIMIT(QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms." The monitoring shall be performed as a Daphnia pulex or
Ceriodaphnia 48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any toxicity test be less than
74%. Effluent samples for self-monitoring purposes must be obtained during representative
effluent discharge below all waste treatment. The first test will be performed after thirty days from
the effective date of this permit during the months of February,May,August, and November.
The parameter code for this test if using Daphnia pulex is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. 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 appropriate parameter code. Additionally, DEM Form AT-1
(original)is to be sent to the following address:
Attention:

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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing,this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

E. ACUTE TOXICITY PERMIT LIMIT(QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms." The monitoring shall be performed as a Daphnia pulex or
Ceriodaphnia 48 hour static test,using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any toxicity test be less than
74%. Effluent samples for self-monitoring purposes must be obtained during representative
effluent discharge below all waste treatment. The first test will be performed after thirty days from
the effective date of this permit during the months of February, May, August, and November.
The parameter code for this test if using Daphnia pulex is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. 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 appropriate parameter code. Additionally, DEM Form AT-1
(original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

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 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
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
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.
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

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.
3. Need to Halt or 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 Facilities
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.

6. Removed Substances
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 143-215.1 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 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.
7. 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.
SECTION D. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the
volume and nature of the permitted discharge. Samples collected at a frequency less than
daily shall be taken on a day and time that is characteristic of the discharge over the entire
period which the sample represents. All samples shall be taken at the monitoring points
specified in this permit and, unless otherwise specified, before the effluent joins or is
diluted by any other wastestream, body of water, or substance. Monitoring points shall
not be changed without notification to and the approval of the Permit Issuing Authority.
•
2. Reporting
Monitoring results obtained during the previous month(s) shall be summarized for each
month and reported on a monthly Discharge Monitoring Report (DMR) Form (DEM No.
MR 1, 1.1, 2, 3) or alternative forms approved by the Director, DEM, postmarked no later
than the 30th day following the completed reporting period.
The first DMR is due on the last day of the month following the issuance of the permit or in
the case of a new facility, on the last day of the month following the commencement of
discharge. Duplicate signed copies of these, and all other reports required herein, shall be
submitted to the following address:
Division of Environmental Management

3. Flow Measurements
Appropriate flow measurement devices and methods consistent with accepted scientific
practices shall be selected and used to ensure the accuracy and reliability of measurements
of the volume of monitored discharges. The devices shall be installed, calibrated and
maintained to ensure that the accuracy of the measurements are consistent with the accepted
capability of that type of device. Devices selected shall be capable of measuring flows with
a maximum deviation of less than 10% from the true discharge rates throughout the range
of expected discharge volumes. Once-through condenser cooling water flow which is
monitored by pump logs, or pump hour meters as specified in Part I of this permit and
based on the manufacturer's pump curves shall not be subject to this requirement.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations
published pursuant to NCGS 143-215.63 et. seq,the Water and Air Quality Reporting Acts,

Water Pollution Control Act, as Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this permit, all test procedures must
produce minimum detection and reporting levels that are below the permit discharge
requirements and all data generated must be reported down to the minimum detection or
lower reporting level of the procedure. If no approved methods are determined capable of
achieving minimum detection and reporting levels below permit discharge requirements,
then the most sensitive (method with the lowest possible detection and reporting level)
approved method must be used.
5. Penalties for Tampering
The Clean Water Act provides that any person who falsifies, tampers with,or knowingly
renders inaccurate, any monitoring device or method required to be maintained under this
permit shall, upon conviction, be punished by a fine of not more than $10,000 per

PART III
OTHER REQUIREMENTS
A. Requirements for Control of Pollutants Attributable to Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs
from industries using the municipal system may be present in the permittee's discharge.At
such time as sufficient information becomes available to establish limitations for such
pollutants, this permit may be revised to specify effluent limitations for
any or all of such other pollutants in accordance with best practicable technology or water
quality standards.
2. Under no circumstances shall the permittee allow introduction of the following wastes in
the waste treatment system:
a. Pollutants which create a fire or explosion hazard in the POTW, including, but not
limited to, wastestreams with a closed cup flashpoint of less than 140 Degrees
Fahrenheit or 60 degrees centigrade using the test methods specified in ATSM
standards D-93-79, D-93-80, or D-3278 (incorporated by reference, see 40 CFR
260.11). This prohibition does not apply to any aqueous solution containing less than
24 percent alcohol by volume which would otherwise be a hazardous waste under 40
CFR 261.21 by virtue of having a closed cup flashpoint of less than 140 degrees
Fahrenheit or 60 degrees centigrade;
b. Wastes which will cause corrosive structural damage to treatment works, and in no
discharges with pH less than 5.0 standard units unless the system is specifically
designed to accommodate such discharges;
c. Solid or viscous substances in amounts which cause obstructions to the flow in sewers
or interference with the proper operation of the treatment works;
d. Wastewaters at a flow rate and/or pollutant concentration which will cause an
inhibition or disruption of the POTW, its treatment processes, operation, or sludge
use and disposal;
e. Heat in amounts which will inhibit biological activity in the treatment works,resulting
in interference but in no case heat in such quantities that the temperature at the treatment
works influent exceeds 40°C (104°F) unless the works are designed to
accommodate such heat;
f. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in
amounts that will cause interference or pass through;
g. Pollutants which result in the presence of toxic gases, vapors, or fumes within the
POTW in quantity that may cause acute worker health and safety problems;
h. Any trucked or hauled pollutants,except at discharge points designated by the POTW.
3. With regard to the effluent requirements listed in Part I of this permit, it may be necessary
for the permittee to supplement the requirements of the Federal Pretreatment Standards (40
CFR, Part 403) to ensure compliance by the permittee with all applicable effluent
limitations. Such actions by the permittee may be necessary regarding some or all of the
industries discharging to the municipal system.

Part III
4. The permittee shall require any industrial discharges into the permitted system to meet
Federal Pretreatment Standards promulgated in response to Section 307(b) of the Act.
Prior to accepting wastewater from any significant industrial user,the permittee shall either
develop and submit to the Division a Pretreatment Program for approval per 15 NCAC 2H
.0907(a) or modify an existing Pretreatment Program per 15 NCAC 2H .0907(b).
5. This permit shall be modified, or alternatively, revoked and reissued, to incorporate or
modify an approved POTW Pretreatment Program or to include a compliance schedule for
the development of a POTW Pretreatment Program as required under Section 402(b)(8)of
the Clean Water Act and implementing regulations or by the requirements of the approved
State pretreatment program,as appropriate.
B. Construction
No construction of wastewater treatment facilities or additions to add to the plant's treatment
capacity or to change the type of process utilized at the treatment plant shall be begun until Final
Plans and Specifications have been submitted to the Division of Environmental Management
and written approval and Authorization to Construct has been issued.
C. Groundwater Monitoring
The permittee shall, upon written notice from the Director of the Division of Environmental
Management,conduct groundwater monitoring as may be required to determine the compliance
of this NPDES permitted facility with the current groundwater standards.
D. Publicly Owned Treatment Works
All POTWs must provide adequate notice to the Director of the following:
1. Any new introduction of pollutants into the POTW from an indirect discharger which
would be subject to section 301 or 306 of CWA if it were directly discharging those
pollutants; and
2. Any substantial change in the volume or character of pollutants being introduced into that
POTW by a source introducing pollutants into the POTW at the time of issuance of the
permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality
and quantity of effluent introduced into the POTW, and (2) any anticipated impact of the
change on the quantity or quality of effluent to be discharged from the POTW.

collected in one calendar month.
c. The weekly average, other than for fecal coliform
bacteria, is the arithmetic mean of all the samples
collected during one calendar week (Sun-Sat) . The weekly
average for fecal coliform bacteria is the geometric mean of
all samples collected in one calendar week (Sun-Sat) .
M 5

d. DEM or Division: means the Division of Environmental
Management, Department of Natural Resources and Community
Development.
e. EMC: used herein means the North Carolina Environmental
Management Commission.
f. Flow, M3/day (MGD) : The flow limit expressed in this
permit is the 24 hour average flow, averaged monthly. It is
determined as the arithmetic mean of the total daily flows
recorded during the calendar month.
g. Arithmetic Mean: The arithmetic mean of any set of
values is the summation of the individual values divided by
the number of individual values.
h. 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) .
i. Composite Sample: These samples consist of grab samples
collected at equal intervals and combined proportional to
flow, a sample continuously collected proportionally to
flow, or equal volumes taken at varying time intervals. If a
composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent
grab samples shall be no greater than hourly. Intervals
between effluent grab samples shall be no greater than
hourly except where the detention time of the wastewater in
the facility is greater than 24 hours, in which case, the
interval between grab samples shall be no greater in number
of hours than the detention time in number of days;
provided, however, in no case may the time between effluent
grab samples be greater than six hours nor the number of
grab samples less than four during any discharge period of
24 hours or less.
j . Grab Sample: Grab samples are individual samples
collected over a period of time not exceeding 15 minutes;
the grab sample can be taken manually.

designated herein more frequently than required by this
permit, using approved analytical methods as specified
above, the results of such monitoring shall be included in
the calculation and reporting of the values is required in
the DMR. Such increased frequency shall also be indicated.
The DEM may require more frequent monitoring or the
monitoring of other pollutants not required in this permit
by written notification.
7. Records Retention
All records and information resulting from the monitoring
activities required by this Permit including all records of
analyses performed and calibration and maintenance of
instrumentation and recordings from continuous monitoring
instrumentation shall be retained for a minimum of three (3)
years. This period of retention shall be extended during the
course of any unresolved litigation or if requested by the
Division of Environmental Management or the Regional
Administrator of the Environmental Protection Agency.

PART II GENERAL CONDITIONS
A. MANAGEMENT REQUIREMENTS
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. Any anticipated facility
expansions, production increases, or process modifications
which will result in new, different, or increased discharges
of pollutants must be reported by submission of a new NPDES
application or, if such changes will not violate the
effluent limitations specified in this permit, by notice to
the DEM of such changes. Following such notice, the permit
may be modified to specify and limit any pollutants not
previously limited.
2. Noncompliance Notification
The permittee shall report by telephone to either the
central office or appropriate regional office of the
division as soon as possible but in no case more than 24
hours or on the next working day following the occurrence or
first knowledge of the occurrence of any of the following:
a. Any occurrence at the water pollution control
facility which results in the discharge of significant
amounts of wastes which are abnormal in quantity or
characteristic, such as the dumping of the contents of a
sludge digester, the known passage of a slug of
hazardous substance through the facility or any other
unusual circumstances.
b. Any process unit failure, due to known or unknown
reasons, that render the facility incapable of adequate
wastewater treatment, such as mechanical or electrical
failures of pumps, aerators, compressors, etc.
c. Any failure of a pumping station, sewer line, or
treatment facility resulting in a by-pass directly to
receiving waters without treatment of all or any portion
of the influent to such station or facility.
d. Any time that self-monitoring information indicates
that the facility has gone out of compliance with its
NPDES permit limitations.
M 8

Persons reporting such occurrences by telephone shall also
file a written report in letter form within 15 days
following first knowledge of the occurrence.
3. Facilities Operation
The permittee shall at all times maintain in good working
order and operate as efficiently as possible all treatment
or control facilities or systems installed or used by the
permittee to achieve compliance with the terms and
conditions of this permit.
4. Adverse Impact
The permittee shall take all reasonable steps to minimize
any adverse impact to navigable waters resulting from
noncompliance with any effluent limitations specified in
this permit, including such accelerated or additional
monitoring as necessary to determine the nature and impact
of the noncomplying discharge.
5. Bypassing
Anydiversion from or bypass ypass of facilities is prohibited,
except (i) where unavoidable to prevent loss of life or
severe property damage, or (ii) where excessive storm
drainage or runoff would damage any facilities necessary for
compliance with the effluent limitations and prohibitions of
this permit. All permittees who have such sewer bypasses or
overflows of this discharge shall submit, not later than six
months from the date of issuance of this permit, detailed
data or engineering estimates which identify:

3. Definitions
a. The monthly average, other than for fecal colifarm bacteria, is the
arithmetic mean of all the composite samples collected in a one-
month period. The monthly average for fecal coliform bacteria is
the geometric mean of samples collected in a one-month period.
b. The weekly average, other than for fecal coliform bacteria, is the
arithmetic mean of all the composite samples collected during a
one-week period. The weekly average for fecal coliform bacteria
is the geometric mean of samples collected in a one-week period.
c. Flow, M3/day (MGD): The flow limit expressed in this permit is the
24 hour average flow, averaged monthly. It is determined as the
arithmetic mean of the total daily flows recorded during the calendar
month.
d. Arithmetic Mean: The arithmetic mean of any set of values is the
summation of the individual values divided by the number of individual
values.
M5

Part I
Permit No. NC
e. 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 equiva-
lent 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 ).
f. Composite Sample: A "composite sample" is any of the following:
(1 ) Not less than four influent or effluent portions collected
at regular intervals over a period of 24 hours and composited
in proportion to flow.
(2) Not less than four equal volume influent or effluent portions
collected over a period of 24 hours at intervals proportional
to the flow.
(3) An influent or effluent portion collected continuously over
a period of 24 hours at a rate proportional to the flow.
g. Grab Sample: A "grab sample" is a single influent or effluent
portion which is not a composite sample. The sample(s) shall be
collected at the period(s) most representative of the total discharge.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC
regulations published pursuant to N. C. G. S. 143-215.63 et seq, The
Water and Air Quality Reporting Act, and to regulations published pursuant

A. MANAGEMENT REQUIREMENTS
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. Any anticipated
facility expansions, production increases, or process modifications which
will result in new, different, or increased discharges of pollutants must
be reported by submission of a new NPDES application or, if such changes
will not violate the effluent limitations specified in this permit, by
notice to the DEM of such changes. Following such notice, the permit
may be modified to specify and limit any pollutants not previously limited.
2. Non compliance Notification
If, for any reason, the permittee does not comply with or will be unable
to comply with any effluent limitation specified in this permit, the per-
mittee shall provide the Division of Environmental Management with the
following information, in writing, within five (5) days of becoming aware
of such condition:
a. A description of the discharge and cause of noncompliance; and
b. The period of noncompliance, including exact dates and times; or,
if not corrected; the anticipated time the noncompliance is expected
to continue, and steps being taken to reduce, eliminate and prevent
recurrence of the noncomplying discharge.
3. Facilities Operation
The permittee shall at all times maintain in good working order and
operate as efficiently as possible all treatment or control facilities
or systems installed or used by the permittee to achieve compliance with
the terms and conditions of this permit.
4. Adverse Impact
The permittee shall take all reasonable steps to minimize any adverse
impact to navigable waters resulting from noncompliance with any effluent
limitations specified in this permit, including such accelerated or
additional monitoring as necessary to determine the nature and impact of
the noncomplying discharge.
5. Bypassing
Any diversion from or bypass of facilities necessary to maintain compliance
with the terms and conditions of this permit is prohibited, except (i) where
M 8 & I 7

unavoidable to prevent loss of life or severe property damage, or
(ii ) where excessive storm drainage or runoff would damage any facilities
necessary for complaince with the effluent limitations and prohibitions
of this permit. All permittees who have such sewer bypasses or overflows
of this discharge shall submit, not later than six months from the date
of issue of this permit, detailed data or engineering estimates which
identify:
a. The location of each sewer system bypass or overflow;
b. The frequency, duration and quantity of flow from each sewer
system bypass or overflow.
This requirement is waived where infiltration/inflow analyses are
scheduled to be performed as part of an Environmental Protection Agency
facilities planning project.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the
course of treatment or control of wastewaters shall be disposed of 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.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards to
prevent the discharge of untreated of inadequately treated wastes
during electrical power failures either by means of alternate power
sources, standby generators or retention of inadequately treated efflu-
ent. Should the treatment works not include the above capabilities at
time of permit issuance, the permittee must furnish within six months
to the permitting authority, for approval , an implementation schedule
for their installing, or documentation demonstrating that such measures
are not necessary to prevent discharge of untreated or inadequately
treated wastes. Such documentation shall include frequency and duration

PART III OTHER REQUIREMENTS
A. Requirements for Effluent Limitations on Pollutants Attributable to
Industrial Users
1. Effluent limitations from this discharger are listed in Part I of this permit.
It is apparent that other pollutants attributable to inputs from major
contributing industries using the municipal system may also be present in the
permittee's discharge. At such time as sufficient information becomes
available to establish limitations for such pollutants, this permit may be
revised to specify effluent limitations for any or all of such other pollutants
in accordance with best practicable technology or water quality standards.
2. Under no circumstances shall the permittee allow introduction of the following
wastes into the waste treatment system:
a. Wastes which create a fire or explosion hazard in the treatment works.
b. Wastes which will cause corrosive structural damage to treatment works.
c. Solid or viscous substances in amounts which cause obstructions to the
flow in sewers or interference with the proper operation of the treatment
works.
d. Wastewaters at a flow rate and/or pollutant discharge rate which is
excessive over relatively short time periods so as to cause a loss of
treatment efficiency.
e. Heat in amounts which will inhibit biological activity in the treatment
works resulting in interference but in no case heat in such quaotitieso
that the temperature at the treatment works influent exceeds 40 C (104 F)
unless the works are designed to accomodate such heat. (After August 25, 1981)
3. With regard to the effluent requirements listed in Part I of this permit,
it may be necessary for the permittee to supplement the requirements of the
Federal Pretreatment Standards (40 CFR, Part 403) to ensure compliance by
the permittee with all applicable effluent limitations. Such actions by
the permittee may be necessary regarding some or all of the major contri-
buting industries discharging to the municipal system.
The permittee shall require each major contributing industry subject to
pre-treatment standards or any other applicable requirements promulgated
pursuant to Section 307 of the Act to submit to the permittee periodic
notice (at intervals not to exceed 9 months) regarding specific actions taken
to achieve full compliance with the requirements of Section 307. Starting
on the permittee shall submit semi-annually to the permit
issuing authority a report summarizing the progress of all known major
contributing industries subject to the requirements of Section 307 towards
full compliance with such requirements. Such report shall include at
least the following information:
M 13

PART III
Page of
Permit No. NC
a. A narrative summary of actions taken by the permittee to ensure
that all major contributing industries comply with the requirements
of Section 307.
b. The number of major contributing industries using the treatment
works, divided into SIC group categories.
c. The number of major contributing industries in full compliance
with the requirements of Section 307, or not subject to these
requirements (e.g. , discharge only compatible pollutants).
d. A list identifying by name those major contributing industries
presently in violation of the requirements of Section 307.
4. Immediately upon issuance of this permit, the permittee shall establish
and implement a procedure to obtain from all major contributing indus-
tries specific information on the quality and quantity of effluents intro-
duced by such industrial users. The following information shall be
reported to the permitting agency on a quarterly basis beginning
; quarterly reports reflecting no change from the previous quarter
may simply relate this fact, without submitting repetitive data.
a. Section IV, Standard Form A shall be completed and submitted for
each major contributing industry.
b. Information on the municipal facility as a whole is to be reported
on the monthly Monitoring Report Form (DEM - No. MR 1 .0, 1 .1 , 1 .2, and
1 .3).
Once the specific nature of industrial contributions has been identified,
data collection and reporting requirements may be levied for other
parameters in addition to those included on Form (DEM No. 1 .0, 1 .1 ,
1 .2, and 1 .3).
5. Based on the information regarding industrial inputs reported by the
permittee pursuant to the preceding paragraph, the permittee will be
notified by the permitting authority of the availability of industrial
effluent guidelines on which to calculate allowable inputs of incompatible
pollutants based on BPT for each industry group. Copies of guidelines
will be provided as appropriate. Not later than 120 days following
receipt of this information, the permittee shall submit to the permitting
authority calculations reflecting allowable inputs from each major con-
tributing industry. The permittee shall also require all such major
contributing industries to implement necessary pre-treatment requirements
(as provided for in 40 CFR, Part 403 ), providing the permitting authority
with notifications of specific actions taken in this regard. At that time,
the permit may be amended to reflect the municipal facility's effluent
requirements for incompatible pollutants.

STAFF REPORT AND RECOMMENDATIONS
Part I - INSPECTION OF EXISTING WASTEWATER TREATMENT PLANT SITE
1 . Place visited: Town of Lowell ','astewater Treatment Plant
Gaston County, North Carolina
2. Date: January 29, 1981
3. By: David T. Adkins1 l' 'jL
4. Person contacted: Ralph Waters, Town Manager
5. Directions to site: Take Powell Drive (S. R. 2380) off of N. C.
Highway 7 and proceed to the end of the road.
6. The bearing and distance to the point of effluent discharge is:
Approximately 1200 feet east of the wastewater treatment plant at
Longitude 81004'40" and Latitude 35016'10".
7. Size: 2-3 acres
0. Topography: Rolling, 5-15t slopes
9. Location of nearest dwelling?: No dwellings within 11100 feet.
10. Receiving Stream: South Fork of Catawba River
( :) classification: n-IT
(h) Minimum 7-Day, 10-Year discharge at site: 120 cfs
(c) Usage: Source of water supply fnr drinking, culinary, or food-
processing purposes and any other best usage requiring waters
of lower quality.
Part II - DESCRIPTIO`d OF EXISTINa TREATMENT WORKS
The existing wastewater treatment facility is a 0.60 MGD contact
stabilization plant consisting of a contact aeration zone, a reaeration
zone, final clarification with sludge return facilities, chlorination
facilities, an aerobic digester, sludge drying beds, a conminutor with
a bar screen bypass, a Parshall Flume, and an influent pump station.
The available data on the existing facility indicates the plant is
achieving an average effluent BOD5 of approximately 10 mg/1 , an average
effluent TSS of 28 mg/1, with an average flow of approximately 300,000 gpd.
Part III - EVALUATION AND RECOMMENDATIONS
The existing facility treats practically 100% domestic wastewater which is
the ideal situation for a contact stabilization type treatment plant.
The limited data available indicates that the facility is meeting
effluent limitations at approximately one-half the design capacity of the
plant. It is felt that, with continued proper operation and maintenance

Page Two
and a very small percentage of industrial waste, the existing facility
can protect the water quality of the receiving stream and meet the
effluent limitations assigned to this point of discharge by our
Technical Services Branch up to the design capacity of the plant.
Therefore, it is recommended that a Permit be issued containing the
following effluent limitations:
Parameters Limitations
Flow 0.60 MGD
BOD5 30 mg/1
TSS 30 mg/1
Fecal Coliforri Bacteria (Geometric clean) 1000/100 ml
pH 6-9
Temperature 90/a5°F

Dear Mr. Cox:
This is to reply to the letter from B. Keith Overcash, P. E. ,
to Mayor Gene Morrow of date of December 1, 1980. Dean Van Pelt
has replaced Mr. Morrow as Mayor.
As you may or may not be aware, Lowell has a unique location
with respect to upstream and downstream sampling. Immediately
upstream is the Guilford Mills discharge and immediately downstream
is the McAdenville discharge . Mr. Russell Stepp, Jr. , our
operator, has tried to work out using their information as
our data. It appears that the State will not accept this.
Mr. Stepp, Jr. , did do the sampling in October and November
of this year. You should have the information for October.
The November information should be there soon.
We request that the NPDES Permit be renewed.
Sincerely,

3. Definitions
a. The monthly average, other than for fecal coliform bacteria, is the
arithmetic mean of all the composite samples collected in a one-
month period. The monthly average for fecal coliform bacteria. is
the geometric mean of samples collected in a one-month period.
b. The weekly average, other than for fecal coliform bacteria, is the
arithmetic mean of all the composite samples collected during a
one-week period. The weekly average for fecal coliform bacteria
is the geometric mean of samples collected in a one-week period.
c. Flow, M3/day (MGD): The flow limit expressed in this permit is the
24 hour average flow, averaged monthly. It is determined as the
arithmetic mean of the total daily flows recorded during the calendar
month.
d. Arithmetic Mean: The arithmetic mean of any set of values is the
summation of the individual values divided by the number of individual
values.
M5

Part I
Page of
Permit No. NC
e. 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 equiva-
lent 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).
f. Composite Sample: A "composite sample" is any of the following:
(1 ) Not less than four influent or effluent portions collected
at regular intervals over a period of 24 hours and composited
in proportion to flow.
(2) Not less than four equal volume influent or effluent portions
collected over a period of 24 hours at intervals proportional
to the flow.
(3) An influent or effluent portion collected continuously over
a period of 24 hours at a rate proportional to the flow.
g. Grab Sample: A "grab sample" is a single influent or effluent
portion which is not a composite sample. The sample(s) shall be
collected at the period(s) most representative of the total discharge.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC
regulations published pursuant to N. C. G. S. 143-215.63 et seq, The

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. Any anticipated
facility expansions, production increases, or process modifications which
will result in new, different, or increased discharges of pollutants must
be reported by submission of a new NPDES application or, if such changes
will not violate the effluent limitations specified in this permit, by
notice to the DEM of such changes. Following such notice, the permit
may be modified to specify and limit any pollutants not previously limited.
2. Non compliance Notification
If, for any reason, the permittee does not comply with or will be unable
to comply with any effluent limitation specified in this permit, the per-
mittee shall provide the Division of Environmental Management with the
following information, in writing, within five (5) days of becoming aware
of such condition:
a. A description of the discharge and cause of noncompliance; and
b. The period of noncompliance, including exact dates and times; or,
if not corrected; the anticipated time the noncompliance is expected
to continue, and steps being taken to reduce, eliminate and prevent
recurrence of the noncomplying discharge.
3. Facilities Operation
The permittee shall at all times maintain in good working order and
operate as efficiently as possible all treatment or control facilities
or systems installed or used by the permittee to achieve compliance with
the terms and conditions of this permit.
4. Adverse Impact
The permittee shall take all reasonable steps to minimize any adverse
impact to navigable waters resulting from noncompliance with any effluent
limitations specified in this permit, including such accelerated or
additional monitoring as necessary to determine the nature and impact of
the noncomplying discharge.
5. Bypassing
Any diversion from or bypass of facilities necessary to maintain compliance
with the terms and conditions of this permit is prohibited, except (i) where
M 8 & I 7

scheduled to be performed as part of an Environmental Protection Agency
facilities planning project.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the
course of treatment or control of wastewaters shall be disposed of 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.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards to
prevent the discharge of untreated of inadequately treated wastes
during electrical power failures either by means of alternate power
sources, standby generators or retention of inadequately treated efflu-
ent. Should the treatment works not include the above capabilities at
time of permit issuance, the permittee must furnish within six months
to the permitting authority, for approval , an implementation schedule
for their installing, or documentation demonstrating that such measures
are not necessary to prevent discharge of untreated or inadequately
treated wastes. Such documentation shall include frequency and duration

PART III OTHER REQUIREMENTS
A. Requirements for Effluent Limitations on Pollutants Attributable to
Industrial Users
1. Effluent limitations from this discharger are listed in Part I of this
permit. It is apparent that other pollutants attributable to inputs
from major contributing industries using the municipal system may also be
present in the permittee's discharge. At such time as sufficient infor-
mation becomes available to establish limitations for such pollutants,
this permit may be revised to specify effluent limitations for any or
all of such other pollutants in accordance with best practicable technology
or water quality standards.
2. Under no circumstances shall the permittee allow introduction of the following
wastes into the waste treatment system:
a. Wastes which create a fire or explosion hazard in the treatment works.
b. Wastes which will cause corrosive structural damage to treatment works.
c. Solid or viscous substances in amounts which cause obstructions to the
flow in sewers or interference with the proper operation of the treatment
works.
d. Wastewaters at a flow rate and/or pollutant discharge rate which is
excessive over relatively short time periods so as to cause a loss of
treatment efficiency.
3. With regard to the effluent requirements listed in Part I of this permit,
it may be necessary for the permittee to supplement the requirements of the
Federal Pretreatment Standards (40 CFR, Part 128) to ensure compliance by
the permittee with all applicable effluent limitations. Such actions by
the permittee may be necessary regarding some or all of the major contri-
buting industries discharging to the municipal system.
The permittee shall require each major contributing industry subject to
pre-treatment standards or any other applicable requirements promulgated
pursuant to Section 307 of the Act to submit to the permittee periodic
notice (at intervals not to exceed 9 months) regarding specific actions taken
to achieve fy11 compliance with the requirements of Section 307. Starting
on JUL 1 ` the permittee shall submit semi-annually to the permit
issuing authority a report summarizing the progress of all known major con-
tributing industries subject to the requirements of Section 307 towards full
compliance with such requirements. Such report shall include at least the
following information:
M 13

PART III
Page of
Permit No. NC
a. A narrative summary of actions taken by the permittee to ensure
that all major contributing industries comply with the requirements
of Section 307.
b. The number of major contributing industries using the treatment
works, divided into SIC group categories.
c. The number of major contributing industries in full compliance
with the requirements of Section 307, or not subject to these
requirements (e.g. , discharge only compatible pollutants).
d. A list identifying by name those major contributing industries
presently in violation of the requirements of Section 307.
4. Immediately upon issuance of this permit, the permittee shall establish
and implement a procedure to obtain from all major contributing indus-
tries specific information on the quality and quantity of effluents intvo-
duced by such industrial users. The following information shall be
reported to the permitting agency on a quarterly basis beginning
JUL J. t. ; ; quarterly reports reflecting no change from the previous quarter
may simply relate this fact, without submitting repetitive data.
a. Section IV, Standard Form A shall be completed and submitted for
each major contributing industry.
b. Information on the municipal facility as a whole is to be reported
on the monthly Monitoring Report Form (DEM - No. MR 1 .0, 1 .1 , 1 .2, and
1 .3).
Once the specific nature of industrial contributions has been identified,
data collection and reporting requirements may be levied for other
parameters in addition to those included on Form (DEM No. 1 .0, 1 .1 ,
1 .2, and 1 .3).
5. Based on the information regarding industrial inputs reported by the
permittee pursuant to the preceding paragraph, the permittee will be
notified by the permitting authority of the availability of industrial
effluent guidelines on which to calculate allowable inputs of incompatible
pollutants based on BPT for each industry group. Copies of guidelines
will be provided as appropriate. Not later than 120 days following
receipt of this information, the permittee shall submit to the permitting
authority calculations reflecting allowable inputs from each major con-
tributing industry. The permittee shall also require all such major
contributing industries to implement necessary pre-treatment requirements

STAFF REPORT AND RECOMMENDATIONS
Part I - INSPECTION OF EXISTING WASTEWATER TREATMENT PLANT SITE
1 . Place visited: Town of Lowell Wastewater Treatment Plant
Gaston County, North Carolina
2. Date: January 6, 1976
3. By: B. Keith Overcash r`Carry D. Coble _ R
4. Person contacted: Ralph Waters, Town Manager
5. Directions to site: Take Powell Drive (SR 2330) off of N. C. Highway
7 and proceed to the end of the road.
6. The bearing and distance to the point of effluent discharge is:
Approximately 1200 feet east of the wast water treatment plant at
Longitude 31004'40" and Latitude 35016'10 .
7. Size: 2-3 acres
3. Topography: >Zolling, 5-15% slopes
9. Location of nearest dwelling: No dwellings within 1000 feet.
10. Receiving Stream: South Fork of Catawba River
(a) Classification: A-II
(b) Minimum 7-Day, 10-Year discharge at site: 120 cfs
(c) Usage: Source of water supply for drinking, culinary, or food-
processing purposes and any other best usage requiring waters
of lower quality.
Part II - DESCRIPTIN OF EXISTING TREATMENT WORKS
The existing wastewater treatment facility is a 0.60 MGD contact stabilization
type consisting of a contact aeration zone, a reaeration zone, final
clarification with sludge return facilities, chlorination facilities,
an aerobic digester, sludge drying beds, a comninutor with a bar screen
bypass, a Parshall Flume, and an influent pump station.
On the day of this investigation, the plant seemed to have a solids problem.
The effluent was cloudy and contained some trash. It did not appear
that the sludge drying beds were being used.
The available data on the existing facility indicates that an average
effluent BOD5 of approximately 10 mg/1 , an average effluent TSS of 12 mg/1 ,
and an average effluent TKN of approximately 10 mg/1 has been maintained
at the plant, with an average flow of approximately 300,000 gpd.

Page 2
PART III - EVALUATION AND RECOMMENDATIONS
The existing facility treats practically 100% domestic waste which is
the ideal situation for a contact stabilization type municipal treatment
plant. The limited data available indicates that the facility is meeting
effluent limitations at approximately one-half the design capacity of the
plant. It is felt that, with continued proper operation and maintenance
and a very small percentage of industrial waste, the existing facility
can protect the water quality of the receiving stream and can meet the
effluent limitations assigned to this point of discharge by our Technical
Services Branch up to the design capacity of the plant.
Therefore, it is recommended that a Permit be issued containing the following
effluent limitations:
Parameters Limitations
Flow 0.60 MGD
BOD5 30 mg/1
TSS 30 mg/1
Fecal Coliform Cacteria (Geometric Mean) 200/100 ml
pH 6-9
Temperature 90/e5°F
