Dear Mr. Helms:
Our records indicate that NPDES Permit No. NCO041360 was issued on April 20, 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. 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 hiW://h2o.enr.state.ne.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

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.
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 parry, 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
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3 Week
Samples are collected three times per week on three separate calendar days.
Act or "the Act"
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 Dav
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 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
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.
Version 612012003

NPDES Permit Requirements
Page 2 W16
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 Imay 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).
DWO 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 an
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
A measure of, flow taken at the time of sampling, when both the sample and flow will be representative of the total
discharge.
Version 612012003

and compaction. Also, the facility does not have a sludge holding tank. This should be removed
from the facility description in the permit. The facility does include a bar screen. This should be
added to the description in the permit.
Provided the above changes are noted, ' office recommends that the permit be.reissued.

Gaston County BOE- East Gaston High School

The NPDES Unit received your permit renewal application on January 23, 2001. 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 NCO041360 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 520.
Sincerely,
Valery Stephens

Subject: Renewal Notice
NPDES Permit NCO041360
East Gaston High School
Gaston County
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 [phone], extension 547. You may also contact the Mooresville Regional
Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items you must submit with
the permit renewal application. If you have any questions, please contact me at the telephone number or e-mail address listed
below.

This letter is in response to the Compliance Evaluation
Report for East Gaston High School on November 20, 2003
by Mr. Barry Love. A deficiency was noted in reference to
the sand filters. Please note that there are two sand filter
beds at this facility. One is always in use while the other
one Is undergoing maintenance such as removal of solids,
raking and preparing sand and removal of vegetation.
During the inspection, bed 2 noted in the report was
scheduled to be taken off line and bed 1 put on line. This
was delayed due to some wet weather delaying the
maintenance of bed 1.

PERMIT:
The permit authorizes the continued operation of an existing 0.025 MGD wastewater treatment
facility consisting of a bar screen, equalization basin, aeration basin, clarifier, dual recirculating sand filters,
and chlorine contact with gas chlorination.
The permit for this facility became effective on June 1, 2001 and will expire on February 28, 2005.
RECORDS AND REPORTS:
Records and reports consisting of monthly monitoring reports, process control data, Operator -in -
Responsible Charge/maintenance log, and sludge records were reviewed at the time of the inspection. The
records were organized and well maintained.
FACILITY SITE REVIEW/OPERATIONS & MAINTENANCE:
All treatment units seemed to be operating properly, and the facility was well maintained. The
mixed liquor appeared to be well mixed and adequately oxygenated. The sand filters had some ponding
and vegetation. The Permit requires that the facility be operated and maintained to optimum efficiency at
all times. The bar screenings are disposed in the Gaston County landfill. The process control program
consists of dissolved oxygen (DO) and settleability tests. Sludge wasting is based on settleable solids and
DO.
The facility is staffed with one Grade II operator. A certified back-up operator has been
designated and is available when the ORC is unable to visit the facility. The ORC was very knowledgeable
of the treatment processes and equipment used at the plant.
LABORATORY:
Par Laboratory, Inc. (Certification #20) in Charlotte, North Carolina provides analytical support
including field parameters. The lab was not evaluated during this inspection.
EFFLUENT/RECEIVING WATERS:
The facility discharges into an unnamed tributary to Taylors Creek, which is a Class WS-IV water
in the Catawba River Basin. The receiving stream was not evaluated.
SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period October 2002 through September 2003. All
monitoring frequencies were correct. No limit violations were reported.
FLOW MEASUREMENT:
Instantaneous flow is measured at the effluent by the bucket and stopwatch method.
SLUDGE DISPOSAL:
Sludge is pumped from the aeration basin and clarifier at Christmas and during the summer when
school is out by Cline Septic Tank Service and disposed at one of the Charlotte Mecklenburg Utilities
W WTP's.

Gaston County
Dear Dr. Sadler:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount
of $335.45 ($250.00 civil penalty + $85.45 enforcement costs) against the Gaston County
Schools.
This assessment is based upon the following facts: A review has been conducted of the
discharge monitoring report (DMR) submitted by the Gaston County Schools for the month of
January 2002. This review has shown the subject facility to be in violation of the discharge -
limitations found in NPDES Permit No. NC0041360. The violations are summarized in
Attachment A to this letter.
Based upon the above facts, I conclude as a matter of law that the Gaston County Schools
violated the terms, conditions or requirements of NPDES Permit No. NCO041360 and North
Carolina General Statute (G.S.) 143-215.1(a)(6) in the manner and extent shown in Attachment
A. A civil penalty may be assessed in accordance with the maximums established by G.S. 143-
215.6A(a)(2).
Based upon the above findings of fact and conclusions of law, and in accordance with
authority provided by the Secretary of the Department of Environment and Natural Resources
and the Director of the Division of Water Quality, I, D. Rex Gleason, Water Quality Regional
Supervisor for the Mooresville Region, hereby make the following civil penalty assessment
against the Gaston County Schools:

discharging waste into the waters of the State in
violation of the permit daily maximum effluent
limit for Fecal Coliform. .
TOTAL CIVIL PENALTY
Enforcement costs.
TOTAL AMOUNT DUE
Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken
into account the Findings of Fact and Conclusions of Law and the factors set forth at G.S. 143B-
2 82. 1 (b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public
health, or to private property resulting from the violation;
(2) The duration and gravity of the violation;
(3) The effect on ground or surface water quantity or quality or on air quality;
(4) The cost of rectifying the damage;
(5) The amount of money saved by noncompliance;
(6) Whether the violation was committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs
over which the Environmental Management Commission has regulatory authority;
and
(8) The cost to the State of the enforcement procedures.
Within thirty days of receipt of this notice, you must do one of the following:
1. Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environment
and Natural Resources (do not include waiver form). Payment of the penalty will
not foreclose further enforcement action for any continuing or new violation(s).
Please submit payment to the attention of:
Point Source ComplianceBnforcement Unit
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
2. Submit a written request for remission or mitigation including a detailed
justification for such request:

A request for remission or mitigation is limited to consideration of the
reasonableness of the amount of the penalty and is not the proper procedure for
contesting the accuracy of any of the statements contained in the assessment letter.
Because a remission request forecloses the option of an administrative hearing,
such a request must be accompanied by a waiver of your right to an administrative
hearing and a stipulation that there are no factual or legal issues in dispute. You
must execute and return to this office the attached waiver and stipulation form and
a detailed statement which you believe establishes whether:
(a) one or more of the civil penalty assessment factors in G.S. 143B-282.1(b)
were wrongfully applied to the detriment of the petitioner;
(b) the violator promptly -abated continuing environmental. damage resulting
from the violations;
(c) the violations were inadvertent or a result of an accident;
(d) the violator had been assessed civil penalties for any previous violation;
(e) payment of the civil penalty will prevent payment for the remaining
necessary remedial actions.
Please submit this information to the attention of:
Ms. Coleen Sullins
Water Quality Section Chief
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Please note that all information presented in support of a request for remission
must be submitted in writing. The Director of the Division of Water Quality will
review the information during a bimonthly enforcement conference and inform
you of his decision in the matter of the remission request. His response will
provide details regarding case status, directions for payment and provision for
further appeal of the penalty to the Environmental Management Commission's
Committee on Civil Penalty Remissions. Please be advised that the Committee
cannot consider information that was not part of the original remission request
considered by the Director and therefore, it is very important that you prepare a
complete and thorough statement in support of your request for remission.
MM
3. Submit a written request for an administrative hearing:
If you wish to contest any statement in this assessment letter, you must request an
administrative hearing. This request must be in the form of a written petition to
the Office of Administrative Hearings and must conform to Chapter 150B of the
North Carolina General Statutes. You must:

File your original petition with the

and
Mail or hand -deliver a copy of the petition to
Mr. Dan Oakley, General Counsel
Department of Environment and Natural Resources
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Failure to exercise one of the options above within !hLrtY- days, as evidenced by a date
stamp (not a postmark) indicating when we received your response, will result in this matter
being referred to the Attorney General's Office with a request to initiate a civil action to collect
the penalty.
Please be advised that any continuing violation(s) may be the subject of a new
enforcement action, including an additional penalty. If you have any questions about this civil

Dear Mr. Helms:
Our records indicate that NPDES Permit No. NCO041360 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 anytime 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

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.

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. V
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 -nf 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.

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
infrequentmaintenance 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 (D' 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
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

4. Bypassing of Treatment 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 thefacility.
(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 Ioss 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.

Page 9 of 14
5. T s2
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 Iimitations 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 peimittee 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 143-2151 and in a manner such
as to prevent any pollutant from such materials from entering waters of the State or navigable
waters of the United States. The 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
permttee 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

Subject: Renewal Notice
NPDES Permit NCO041360
East Gaston High School
Gaston County
Dear Permittee:
The subject permit expires on July 31, 2001. North Carolina Administrative Code (15A NCAC 2H.0105(e)) requires that
an application for permit renewal 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 February 1,
2001. Failure to request renewal of the permit 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 July 31, 2001 (or if continuation of the permit is desired), the current permit
must be renewed. Discharge of wastewater without a valid permit would violate North Carolina General Statute 143-215.1 and
could result in assessment of 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 [phone], extension 547. You.may also contact the Mooresville Regional
Office at [phone] to begin the rescission process.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items you must submit with
the permit renewal application. If you have any questions, please contact me. My telephone number, fax number and e-mail
address are listed at the bottom of this page.
Sincerely,

PART IV - EVALUATION AND RECOMMENDATIONS
Gaston county Schools has applied for renewal of its NPDES permit for the East Gaston High
School WWTP. The plant appeared to be functioning well during'the inspection. However, the sand
filters are overgrown. with weeds and there appears to be some caking. The ORC indicated that he
had ordered new sand.
It appears that other disposal methods are viable. The school appears. to have adequate land
for reuse and possibly even spray irrigation. Also, there is a possibility that the City of Mount Holly
may extend sewer lines to the school in the future.
Page 3

This Office recommends reissuing the NPDES permit if other disposal options do not appear
viable.

Re: 1682 — East Gaston High School
ar-Steve: - ---
Per our conversation with Mr. Mike Parker we request that your office write a letter to
the Gaston County Zoning Department concerning the acceptability of the increase in
wastewater generated by the addition of classrooms as East Gaston High School.
There is an existing treatment plant on the campus (Permit Number NC0041360).
The capacity of the plant is 25,000 GPD. Gaston County Schools have monitored the
flow and report an average flow of 4600 GPD. The proposed addition, based on 528
students at 15 GPD is equal to 7920 GPD. As you can see the increase is within the
capacity of -the. plant.
The Gaston County Zoning Department will not allow a building permit until they
receive a letter from your office. The Contractor is on site and the schedule for
construction has been impacted. Please fax a -letter to:
Mr. Danny Garrett

Re: 1682 — East Gaston High School
Deer Stev
Per our conversation with Mr. Mike Parker we request that your office write a letter to
the Gaston County Zoning Department concerning the acceptability of the increase in
wastewater generated by the addition of classrooms as East Gaston High School.
There is an existing treatment plant on the campus (Permit Number NC0041350).
The capacity of the plant is 25,000 GPD. Gaston County Schools have monitored the
flow and report an average flow of 4600 GPD. The proposed addition, based on 628
students at 15 GILD is equal to 7920 GPD. As you can see the increase is within the
capacity of the plant.
The Gaston County Zoning Department will not allow a building permit until they
receive a letter from your office. The construction is on site and the schedule for
construction has been impacted. Please fax a letter to:
Mr. Danny Garrett
Code Enforcement Administrator
Gaston County Zoning Department
212 West Main Avenue
Gastonia, North Carolina 28053-1678

Permit: Our records do not show ever having a sludge holding tank at the facility. Nothing has
been changed since the system was put in.
Facility Site Review:The fliter beds are designed with a drain at the center of the distrbution box
so the water does not freeze.That is the low spot at each filter bed.The sludge has been removed.
Self- Monitoring:We had no data becuase school was out over the Christmas Holidays, and there
was no flow.
Laboratory:A new worksheet has been made to include a curve for CL2 readings and time
analyzed.

East Gaston High School
Gaston County, NC'
Our records indicate that NPDES Permit No. NCO041360 was
issued on June 24, 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 are Pages 4-5.
Pages 4-5 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, 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 his Office at 704/663-1699 in Mooresville if you
have any questions or need clarification. We look forward to
providing any assistance.

USC 1251, et. seq.
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

a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges samplers 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.

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
orfor infrequent maintenance activities on the flow device.
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 betaken manually. Grab samples must be .
representative of the discharge or the receiving waters.

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).

(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. UFsets
. 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 H, E. 6. (b) (B) of this
permit-
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this

failures either by . means of. alternate power sources, standby, generators or retention of
inadequately treated effluent.
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.
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

CHRONIC TOXICITY TESTING REQUIREMENT (QR_1RLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be.no observable inhibition of reproduction or
significant mortality is °l;1_% (defined as treatment two in the North Carolina procedure
document). The permit holder shall perforniquarterly monitoring using this procedure to establish
compliance with the permit condition. The. first test will be performed after thirty days from
issuance of this peraut-daring the months of MkR 'TuN . Sc P. Dec . Effluent
sampling for.this testing shill be performed at the NPDES permitted final effluent discharge. below
all treatment processes.
All toxicity testing results required as part of this pemiit 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, DEM Form AT71. (original) is to be sent to. the following address:.
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
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 doselresponse 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 this monitoring requirement 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 environmenuil 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.

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 Ahe "maximum daily discharge." This limitation is
identified as "Daily Maximum," in Part.I of the permit.

Part 11
Page 2 of 14
d. The "average annual discharge" is defined as the total mass of all daily discharges
sampled and/or measured during the calendar year on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or
measured during such year. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the year and then dividing this sum by the
number of days the tests were reported. This limitation is defined as "Annual Average"
in Part I of the permit.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal 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 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 a24 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 record er.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.detentiori 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 takeri 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.,

terms and conditions of the NPDES permit or governing rules, regulations and laws.
E. The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity
tests, using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 99% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform -quarterly monitoring using this procedure'to establish compliance
with the permit condition. The first test will be performed after thirty days from issuance of this
permit during the months of March, June, September, and December. 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, 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 this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be reopened 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.

PART IV
ANNUAL ADMINISTERING AND COMPLIANCE MONITORING FEE REQUIREMENTS
A. The permittee must pay the annual administering and compliance monitoring fee within 30
(thirty) days after being billed by the Division. Failure to pay the fee in a timely manner in

PART IV - EVALUATION AND RECOMMENDATIONS
The Permittee, Gaston County Board of Education, has applied
for permit renewal for the East Gaston High School wastewater
treatment plant.
The receiving stream appears to be a 7Q10 = 0 cfs flow
stream. The receiving stream does appear to have positive 30Q2
stream flow. The permitted limits may need to be more stringent
to adequately protect the stream. The initial -permit for this
facility had BOD = 15 mg/l and 4 mg/l NH, as N monthly limits.
During the previous permit renewal the.B6D and NH summer monthly
limits were raised to 23 mg/l and 15 mg/l, respectively. The
winter limits were raised to 30 mg/l for BOD and no NH3 limit.
Continuous flow recording should be required with permit
renewal.
This Office recommends that -the subject Permit be renewed
provided Technical Support concurs.

intersection of S.R. 1924 and S. R. 2083. Travel east on S. R. 2088
approximately one mile. The school is located on the right (south)
side of S. R. 2088.
6. The bearing and distance to the existing point of.effluent discharge
is: Longitude 81004'20" and Latitude 35019'20".
7. Size: Adequate area is available for the proposed new facilities
.and modifications to the existing facilities.
8. Topography: Rolling; approximately 5-10% slopes.
9. Location of nearest dwelling: None within 1000 feet..
10. Receiving Stream: An unnamed tributary to Taylors.Creek
(a) Classification: "C"
(b) Minimum 7-Day, 10-Year discharge at site: 0 cfs
(c) Usage: Fishing, secondary recreation, agriculture, and any other
usage except for primary recreation or as a source of water
supply for drinking, culinary or food -processing purposes.
Part II - DESCRIPTION OF EXISTING AND PROPOSED TREATMENT WORKS
The existing wastewater treatment facility is a package extended aeration
plant, consisting of an influent bar screen, aeration basin (diffused
air),.secondary clarifier and chlorine disinfection.
The applicant proposes to construct additional treatment facilities and
modifications to the existing facilities consisting of -the following:
1. Construct a flow equalization basin preceeding the inlet to the
existing package extended -aeration plant.

Page Two
2. The effluent from the existing package plant's clarifier will be
routed to a proposed dosing tank.
3. The collected wastewater will be pumped from the dosing tank to
.proposed dual surface sand filters (each bed 33'-3" x 67'--2") The
applicant proposes to plant "Liriope plants" in.the filters.
4. Effluent from the sand filters will be routed to a proposed flow
splitter manhole. A portion of the flow will be returned (recirculated)
to the dosing tank while the remainder will be routed to .a proposed
pump station.
5. The wastewater will then be pumped to the existing chlorine disinfection
facilities and then discharged through the existing outfall.
Note: The student enrollment was reported to be 940 in March, 1981.
Part III - EVALUATION AND RECOMMENDATIONS
The proposed additions and modifications are intended to allow the facility
to consistently comply with the effluent limitations contained in NPDES
Permit No. NC 0041360. These limitations are as follows:.

2. 0 & M Evaluation: The facilities appeared to be properly operated and
maintained with one exception. It appears that some of the sand from the
sand filter has been removed and placed on the ground around 'the WWTP.
Some was observed to be placed in surface drainageways subject to storm
runoff. The permittee has been advised to cease this practice.
3. Recommendations -and/or Special Conditions: It is recommended that the

1.
Based on a review of the monthly self -monitoring data for the first quarter
of 1985, the facility was in compliance with existing effluent limitations
with the exception of NH3 - N during March, 1985. It is noted that NH3 - N
returned to compliance in April, 1985.•
2.
The inspector observed that sand containing sludge residue has been removed
from the surface sand filter and spread in areas around the WWTP. A portion
of these areas are prone to washout during storm events. This practice
should be ceased immediately. The operator should consider disposing of
these materials in an approved landfill.
3.
All other areas of the WWTP indicated exhibited proper operation and
maintenance.

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
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.
q. 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
