Permit NC0084689
A. (2.) CHRONIC TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90 %. The testing
shall be performed as a Ceriodaphnia dubia 7day pass/fail test. The tests will be performed during
the months of February,May,August and November. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center
Raleigh,N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity(AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the
report with the notation of"No Flow" in the comment area of the form. The report shall be submitted
to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,then
monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test
requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

the wastewater discharged during the sample period.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act(CWA),as amended,33 USC 1251,et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which
is not a designed or established or operating mode for the facility.
Calendar Day

consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
•
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and

Dear Mr. Price:
Our records indicate that NPDES Permit No.NC0084689 was issued on March 3, 2005
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.I 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. For new permits/facilities,the Division may supply an initial small stock of these
forms; however, if you fail to receive the forms,please contact this Office as quickly as possible.
The forms, including directions for their completion, and other important information are also
• available at http://h2o.enr.state.nc.us/NPDES/documents.html. 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 fee may be required for your facility; if so, you will
receive 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

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.
To maintain compliance with discharge limitations,proper operation and maintenance of
a wastewater treatment facility and the development of a process control program are essential.
For those facilities having chlorine tablet disinfection,please be advised that chlorine tablets
approved for wastewater treatment use must be used; swimming pool tablets are not approved.
Also, be advised that DWQ staff need to have access to the facility's discharge point into the
receiving stream;please maintain a path along the outfall line to facilitate that access.
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 $25,000 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 Special Order by
Consent(SOC)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 Division of
Water Quality rescind the Permit or request that DWQ reissue the Permit 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

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

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

7. Describe the treatment process(es) for the raw water:
Raw water is brought into the facility. Then aluminum sulfate is applied as a coagulant.
The water then flows through the Flash Mix, Flocculation, and Sedimentation. After these
steps Chlorine is first applied for pre disinfection. The water then enters the Filter
Process. The next step is additional chlorine for residual, fluoride addition, and
Phosphate addition. It is then moved to clear well and ready for use.
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
We have four filters at the WTP plant that are washed on a 96hour basis. Upon washing
sediment is sent to the lagoons by backwashing the filters. Also every 3 months basins are
washing sending additional sediment to lagoons. After each event the lagoons are allowed
to sit for duration of time to dissipate the Chlorine residual and allow for the sludge to
accumulate on the bottom of the lagoons allowing for the supernatant to be discharged
safely. Once a year the lagoons are dredged of all alum sludge that accumulates in the
lagoons. For land application according to the land application permit (WQ001863)

City of Mount Holly
City of Mount Holly Residuals
Land Application Program
Land Application of Residual Solids (503)
Gaston County
Dear Mr. Price:
In accordance with a written request made by the City of Mount Holly that was received by the
Division of Water Quality (Division) on July 18, 2002, we are forwarding herewith a corrected Permit
No. WQ0001863, issued on December 28, 1999, for the subject residuals land application program.
The following corrections have been made to the permit:
1. The Permittee's request stated that the equalization basin at the wastewater treatment plant is
only cleaned once every five to seven years. It was explained that the 56-dry ton per year
residuals generation rate that was allowed by the permit is really an annualized average of
that which would be expected to be generated during the cleaning event. A normal cleaning
event would put the Permitte in violation of this generation rate/land application limit.
Therefore, the permit has been corrected to reflect the fact that the Permittee may now land
apply up to 280 dry tons of residuals from the equalization basin in a single year. Note that
language has been added to the permit to reinforce the fact that all sampling and analysis
performed on the residuals accumulated in the equalization basin should be done
representatively as well as separately from those performed on the residuals generated by the
activated sludge process.
2. The Division has taken this opportunity to reissue this permit in the format currently being
used for all residuals land application programs. This format was developed to facilitate new
application review procedure, that have been put into place by the Division. Although no
substantive changes have ben made to the conditions contained within this permit, the
Permittee should take the time to review this document to ensure complete familiarity and
understanding of the format and the condition language.
Please replace the entire permit with this corrected permit into Permit No. WQ0001863,
issued on December 28, 1999.

Dear Permittee:
Your NPDES permit expires on February 28,2005. Federal(40 CFR 122.41)and North Carolina(15A NCAC
2H.0105(e))regulations require that permit renewal applications must be filed at least 180 days prior to expiration of the current
permit. If you have already mailed your renewal application,you may disregard this notice.
To satisfy this requirement,your renewal package must be sent to the Division postmarked no later than September 1,
2004. Failure to request renewal by this date may result in a civil assessment of at least$500.00. Larger penalties may be assessed
depending upon the delinquency of the request.
If any wastewater discharge will occur after February 28,2005,the current permit must be renewed. Discharge of
wastewater without a valid permit would violate North Carolina General Statute 143-215.1;unpermitted discharges of wastewater
may be assessed civil penalties of up to$25,000 per day.
If all wastewater discharge has ceased at your facility and you wish to rescind this permit,contact Bob Sledge of the
Division's Compliance Enforcement Unit at(919) 733-5083,extension 547. You may also contact the Mooresville Regional

NPDES Permit NC0084689
Mount Holly WTP
Gaston County,NC
Dear Mr. Nichols:
Our records indicate that NPDES Permit No. NC0084689 was issued on April 27, 2001
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 are Pages 4 and 5.
Pages 4 and 5 set 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, expansion 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 $25,000 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 Special Order by
Consent (SOC) 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 Division of
Water Quality rescind the Permit or request that the Division of Water Quality reissue the Permit
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 of 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 1 of the permit.
c. The "maximum daily discharge"is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily •
Maximum,"in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is,therefore,an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
•
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 1 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 IV -EVALUATION AND RECOMMENDATIONS
The permittee has requested renewal of the subject permit. However, during the site
investigation, Mooresville Regional office staff discovered six (6) additional discharges at this
facility. During the water treatment process Turbidimeters continuously collect and discharge
samples from 6 sample points. Raw(1), settled(1), and filtered(4) turbidity samples, along with
regular laboratory samples are then flushed into an on-site storm drain.
WTP staff estimates the total volume discharged at 12 gallons per minute. During the summer
months (May—Oct.)this plant operates 16 hours a day,therefore, approximately 0.001 MGD is
discharged. In winter months (Oct. through April), the facility operates 12 hour a day.
Therefore, the winter discharge volume is 0.0008 MGD.
A sample was collected from a storm drain at the point where the drain discharges into a ditch
adjacent to nearby railroad tracks (approximately 100 feet from the point at which all the
discharges join at the storm drain). At this location free chlorine was not detectable when
measured with a Hach pocket chlorine field test kit.
Currently the decant from the alum storage lagoon is recycled back through the plant instead of
being discharged at the permitted location. Approximately 100,000 gallons of decant is
returned to the head of the plant two (2) days each week. Therefore, a small portion of the
water collected and discharged by the turbidity meters is water from the permitted lagoon.

t
Page 4
This lagoon effluent is a permitted discharge requiring monthly monitoring, which means the
necessary monthly monitoring of this discharge has not been executed as required by the
current permit.
Terry Gross with the Public Water Supply Section was contacted regarding the turbidity
sampler discharge. He indicated that a large percentage of WTPs are discharging
turbidimeter samples in this fashion. Some enter local wastewater collection systems and
others are discharged through storm water systems.
The lagoon is currently permitted to discharge, but the permittee has no intention of
discharging from the lagoon. A revision should be made to the permit indicating that
discharges from the lagoon will be 0.3 MGD based on the sizing of pumps and piping
capacity associated with this discharge. The WTP will only discharge from this lagoon during
emergency conditions.
This office recommends that the discharge from the laboratory drain and turbidity meters be
added to the current permit as an additional source due to the volumes and potential
contaminants associated with the source. This additional discharge point should be sampled
on a monthly basis and analyzed for the same parameters as currently listed in the permit.

Subject: NPDES Permit Renewal Application
Permit NC0084689
City of Mount Holly WTP
Gaston County
Dear Mr. Nichols:
The NPDES Unit received your permit renewal application on April 28,2000. Thank you for
submitting this package.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff.
That staff member will contact you if further information is needed to complete the permit renewal.
Please note that the NPDES Unit has several vacant positions. This staff shortage has lasted for over a
year and is delaying all permit renewals. Our remaining permit writers are currently reviewing
Authorizations to Construct, speculative limit requests,major permit modifications and 201 plan
updates ahead of permit renewals. This is necessary due to a variety of factors,including mandatory
deadlines in the statutes which govern our program.
If this staff shortage delays reissuance of NC0084689 the existing requirements in your permit
will remain in effect until the permit is renewed (or the Division takes other action). We appreciate
your patience and understanding while we operate with a severely depleted staff. If you have any
additional questions concerning renewal of the subject permit,please contact me at [phone],
extension 538.
Sincerely,
etkettrot

Dear Ms. Jackson:
The City of Mount Holly would like to request the renewal of the above permit.
No significant changes have been made to the process or facility since the last permit
issuance. The discharge line has not been constructed as the City has just obtained an
easement for the line.
The sludge that accumulates in the lagoons is removed and land applied under our
wastewater treatment plant residuals permit -WQ0001863. The nature of the process and
the sludge necessitates removal only about once per five years.
If you have questions, please feel free to contact me at [phone].
Sincerely,

Subject: NPDES Permit Issuance
Permit No. NC0084689
City of Mount Holly WTP
Gaston County
Dear Mr. Nichols:
In accordance with the application for a discharge permit received on July 3, 1995
the Division is forwarding herewith the subject NPDES permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated December 6, 1983.
In response to comments submitted on the draft permit, the monitoring frequencies
for all parameters have been changed from weekly to monthly. In the event that
noncompliance with a permit limitation occurs, the Division reserves the right to reopen the
permit and revise monitoring frequencies to weekly. The requirement for chloride
monitoring has been removed as requested since no reverse osmosis or brine recharge of "
water softeners occurs. Instream turbidity monitoring has been changed to effluent
monitoring as requested since the discharge is to a zero flow stream.
If any parts, measurement frequencies or sampling requirements contained in this
permit are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. This request must be in the
form of a written petition, conforming to Chapter 150B of the North Carolina General
Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer 27447,
Raleigh, North Carolina 27611-7447. Unless such demand is made, this decision shall be
final and binding.
Please take note that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may
be required by the Division of Environmental Management or permits required by the
Division of Land Resources, Coastal Area Management Act or any other Federal or Local
governmental permit that may be required.

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. JMC
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).

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

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 11, 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

Part II
Page 9 of 14
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.

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

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

Subject: Rescission of State Permit No. WQ0003/1'11
Mt. Holly, City- Alum Sludge Lagoon
Gaston County
Dear Mr. Ponder:
Reference is made toward the rescission of the subject State Permit. Staff of our
Permits &Engineering Unit have confirmed that this facility now is under coverage of
NPDES Permit No. NC0084689 which covers both alum sludge lagoons and that this
nondischarge permit is no longer required. Therefore, in accordance with your request,
State Permit No. WQ0003/1/1'1 is rescinded, effective immediately.
If in the future you wish to operate the sludge lagoons under another nondischarge permit,
you must first apply for and receive a new State Permit. Operating without a valid State Permit
will subject the facility to a civil penalty of up to $10,000 per day.
If it would be helpful to discuss this matter further, I would suggest that you contact
Rex Gleason, Water Quality Regional Supervisor, Mooresville Regional Office at
704/663-1699.

Re: Non-NPDES Permit No. WQ0003444
City of Mount Holly- Water Treatment Plant
Gaston County
Dear Mr. Farmer:
The City of Mount Holly wishes to update DEM on our intentions related to the
above referenced permit. We are aware that the current non-discharge permit is coming
up for renewal. However, we believe that renewal of this permit will be unnecessary due
to the proposed issuance of a discharge permit for this facility(NPDES No. NC 0084689).
The NPDES permit has been proposed to be issued effective 10/16/95. The non-discharge
permit is not scheduled to expire until March 31, 1996.
Should it be necessary for the City to make any adjustments in the timing, or if you
need any further information, please feel free to contact Mr. Jeff Fritts or me at (704) 827-
4261. Thank you for your assistance in this matter.

This annual fee is required•by the North Carolina Administrative Code for the cost of administering
and compliance monitoring for an environmental permit. This is not a renewal fee or a penalty.
It is required of any person holding a permit for a treatment facility for any time during the
annual fee period, regardless of the facility's operating status. Failure to pay the fee by the due date
will subject the permit to revocation. Operation of a treatment facility without a valid permit is a violation
and subject to a S10,000 per day fine. If the permit is revoked and you later decide a permit is needed, you
must reapply, with the understanding the permit request may be denied due to changes in environmental, .
regulatory, or modelling conditions. If you do not wish to continue to hold the permit referenced on the front
of this notice, please complete and sign the statement below and return. If you have questions, please contact
the Annual Administering and Compliance Monitoring Fee Coordinator at 919/733-7015 - Ext. 210.
I have read and understand the above information. It is my desire to not pay this fee and
I hereby request that Permit No. VIM 0003 if '9 be rescinded.

PART IV - EVALUATION AND RECOMMENDATIONS
The City of Mount Holly (The City) has requested issuance of
an NPDES Permit to discharge supernatant from two (2) alum sludge
settling lagoons . At the present time, the supernatant is
recycled back through the WTP with the raw water .
In a discussion with DEH-Water Supply Section personnel in
the MRO, the City has been advised by DEH that the proposed point
of discharge is unacceptable due to the proximity of Mount
Holly's and the City of Gastonia's existing water intakes . DEH
personnel indicated that should the request for a discharge
Permit be routed to their Section for comment, a recommendation
for denial would be prepared. The proposed point of discharge is
in an area (the back of a cove) that would provide poor
assimilation/mixing of the wastewater as well as exacerbate any
toxic impacts that may occur (the Lake is considered the point of
impact since the discharge is to a wet-weather ditch) . It is also
possible that should the downstream hydroelectric dam be
activated, the resultant flow patterns may cause the wastewater
to follow a path that would carry it by the existing WTP
intakes .
It was learned from DEH personnel that a more favorable
discharge location has been discussed with the City and DEH. This
location is immediately below the Mountain Island Lake dam
(receiving waters will be Lake Wylie) . DEH personnel feel that
discharging below the dam not only will provide better mixing of
the effluent , but there will be less interfere with other
existing WTP intakes . The City, however, has not yet proposed
this alternative discharge location and is considering the
requested location based entirely on economic factors (a
discharge below the dam will cost ti 66% more than the proposed
location) . The Division, however, must act on the request for the
proposed discharge location as submitted with this application.

Page Four
The staff of this Office is concerned with the potential WQ
impacts that may occur in the back of cove as a result of the
proposed discharge, therefore, we recommend that the discharge be
piped out to the mouth of the cove for better assimilation of the
effluent . Provided technical support concurs with the suggested
discharge location, issuance of an NPDES Permit is recommended.
