Subject: Rescission of NPDES Permit NC0086185
Pumpkin Center School WWTP
Lincoln County
Dear Mr. Putnam:
Division staff has confirmed that the subject permit is no longer required. Therefore, in
accordance with your request, NPDES Permit NC0086185 is rescinded, effective immediately.
If in the future your school system wishes to discharge wastewater to the State's surface waters,
they must first apply for and receive a new NPDES permit. Discharge of wastewater without a
valid NPDES permit will subject the responsible party to a civil penalty of up to $25,000 per day.
If you have questions about this matter, please contact Charles Weaver of my staff at the
telephone number or address listed below.

Dear Mr. Bridgeman,
Phone: [phone] - Fax: [phone]
JAN 16
The compliance and evaluation inspection report for the waste water treatment plant
located at Pumpkin Center Elementary and Middle Schools was received on January 3,
2006. I subsequently forwarded a copy to Water Tech Labs who is the vendor that
employs our ORC(s) and backups. I then called them and discussed with John Gragg the
deficiencies that would need to be corrected by them. Enclosed in the body of this letter
you will find our response actions to all deficiencies as noted by their particular category.
We have been very aggressive in our responses.
The response actions by category are as follows:
• Recordkeeping
I spoke with John Gragg of Water Tech Labs which as noted earlier are our
ORC(s) and do the monitoring and recordkeeping for Lincoln County Schools
waste water treatment plants. They are now aware of the weekend monitoring
requirements and have made the adjustments on their schedule to comply.
• Sand Filters
I spoke with Randy Putnam, Maintenance Director of Lincoln County Schools.
The recirculation pumps were turned off because of electrical problems. These
problems were corrected as of 1/05/06, and the pumps are now operational and
Educating the Future
www.1inco1n.k12.nc.us

functional. In addition the sand filter surface has been routinely cleaned of any
excess algae and/or vegetation.
• Operations and Maintenance
The water infiltration problem at the conduit entering the first switchbox has been
corrected by Brent Turner, Maintenance Supervisor of Lincoln County Schools
and is no longer a safety hazard or concern.
• Effluent Pump Stations
As in the sand filter section, the effluent pump was repaired on 01/05/06 and all
alarms are now operational.
• Effluent Sampling
Failure to monitor the effluent during the week of 7/18/2005 - 7/22/2005 has been
discussed with John Gragg of Water Tech Labs. He understands the seriousness
of this discrepancy will take all necessary precautions to prevent any failure to
monitor incidence in the future. *Note: This failure to monitor violation has been
received under separate cover and is hereby acknowledged. Reference: Notice of

I hope that these actions will be satisfactory and that their completion will assure that we
are back in compliance as required. I am personally committed to keeping North
Carolina's environment as clean as possible and will work diligently to keep Lincoln
County Schools waste water treatment plants compliant in the future.

Subject: NPDES Permit NC0086185
Pumpkin Center Schools WWTP
Lincoln County
Dear Mr. Seagle:
Our records indicate that NPDES Permit No. NC0086185 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 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
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 party, if
necessary.
As mentioned previously,the purpose of this letter is to advise you of the importance of
your NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in
Mooresville if you have any questions or need clarification. We look forward to providing any
assistance.

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 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.
Version 6J20/2003

NPDES Permit Requirements '
Page 2 of 16
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
A measure of flow taken at the time of sampling,when both the sample and flow will be representative of the total
discharge.
Version 6J20/2003

NPDES Permit Requirements
Page 3 of 16
Monthly Average(concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform, the geometric mean of such discharges.
Permit Issuing Authority
The Director of the Division of Water Quality.
Quarterly Average (concentration limit)
The average of all samples taken over a calendar quarter.
Severe property damage
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 excludes economic loss caused by delays in production.
Toxic Pollutant:
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
Upset
An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with
permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by
operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive
maintenance,or careless or improper operation.

Dear Mr. Bridgeman:
This is to acknowledge receipt of the above notice of deficiency. We have corrected the situation
where the weeds were growing by simply removing them. Where the ponding was occurring, we
found a partially blocked line from that filter bed to the wet well. We are currently scheduling to
clear this line which should eliminate the ponding water. Hopefully, these corrections will rectify all
deficiencies so noted. We will continue to be diligent in our effort to properly operate and maintain
the facility as is expected.

Records and reports appeared to be current and kept in accordance with NPDES permit requirements.
FACILITY SITE REVIEW/OPERATIONS&MAINTENANCE:
One of the surface sand filter beds had water ponding in one area while the other bed had
numerous weeds growing on it. Please be advised that the permit requires that the facility be properly
maintained at all times. All other treatment units appeared to be operating properly,and the surrounding
grounds were well maintained.
The facility is staffed with one Grade II ORC. 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 facility.

Dear Mr. Seagle:
After further examination of the recent permit renewal by Division personnel, the Division has modified the
subject permit to add a footnote to the Effluent Limitations and Monitoring Requirements page. This footnote
indicates that sampling for total residual chlorine is required only if chlorine is added to the treatment system. The
UV disinfection system in place at the facility obviates the need for continuous TRC monitoring.
Please find enclosed the revised effluent page. The revised page should be inserted into your permit. The old
page may then be discarded. All other terms and conditions contained in the original permit remain unchanged and
in full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143-
215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit modification are
unacceptable to you, you have the right to an adjudicators hearing upon written request within thirty (30) days
following receipt of this letter. This request must be a written petition conforming to Chapter 150B of the North
Carolina General Statutes, filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North
Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning this permit modification, please contact Charles Weaver of the NPDES

The facility was last inspected by Wes Bell of this office on May 24, 2000.
PERMIT:
The permitted facility is a 0.012 MGD wastewater treatment system consisting of two septic
tanks with dual siphons, two surface sand filter beds, recirculating pump station, UV disinfection
unit, and cascade post aeration. The permit adequately describes the WWTP.
The permit for this facility became effective on 11/1/00 and expires on 2/28/05. The review
period of the self-monitoring reports includes the requirements of the previously issued permit.
RECORDS AND REPORTS:
Records reviewed during the inspection included the Operator-in-Responsible Charge
(ORC)/daily operation and maintenance log and calibration data. No deficiencies were found.
FACILITY SITE REVIEW/OPERATIONS & MAINTENANCE:
The facility appeared to be properly operated and maintained. The gravel was level and no
vegetation was present. The lateral distribution lines appeared to be level. A small area in the sand
bed appeared to be stained with sediment due to a previous rainfall event. The small area did not
appear to be negatively affecting the treatment capability of the sandbed. The land topography has
been modified to prevent this incident from reoccurring and the maintenance director indicated that
the sediment would be removed. The ORC was very knowledgeable of the treatment processes and
equipment used at the facility.
The facility is staffed with one Grade IV ORC. A certified back-up operator has been
designated and is available when the ORC is unable to visit the facility.
LABORATORY:
Water Tech Labs, Inc., (Certification #50) in Granite Falls, North Carolina has been
contracted to provide analytical support. The lab was not evaluated during this inspection. The ORC
performs the on-site tests for pH and TRC under the Water Tech Labs,Inc. laboratory certification.
The pH and TRC meters appeared to be properly calibrated.
EFFLUENT/RECEIVING STREAM:
The facility discharges into Ore Branch, which is a Class C water in the Catawba River
Basin. The facility was not discharging at the time of the inspection. The receiving stream did not
appear to be negatively impacted. The discharge outfall was well maintained and accessible.

SELF-MONITORING PROGRAM:
Self-monitoring reports were reviewed for the period April 2000 through January 2001,
inclusive. No limit violations were reported. No flow was reported on 4/24/00. On 8/7/00 and
1/2/01, the effluent TRC was reported with a"0.00 MGD" as the daily flow. Effluent parameters
shall only be taken when the facility is discharging. The expiration date was not documented on the
back of the April, May, and June 2000 DMRs. All DMRs must be completely filled-out before
submittal to the Division.
FLOW MEASUREMENT:
Effluent flow is measured continuously by a magnetic flow meter with totalizer and chart
recording. The flow meter was last calibrated(when installed)by Johnston,Inc.of Indian Trail,N.C.
on 6/4/99.Flow measurement devices shall be calibrated at a minimum once per year as required by
the 15A North Carolina Administrative Code (NCAC) 2B .0505(b)(1) and the NPDES Permit.
SLUDGE DISPOSAL:
Septage is removed as needed by Robert's Septic Tank Service, Inc., of Maiden,NC. Final
disposal is at the City of Newton Clarks Creek WWTP.
SEWER OVERFLOW:
Please be advised that pursuant to Part II, Section E of your NPDES permit, and North
Carolina Administrative Code (NCAC) 15A 2B .0506 (a)(2), any failure of a collection sewer,
pumping station or treatment facility resulting in a bypass without treatment of all or any portion of
the wastewater shall be reported to the central office or the appropriate regional office (Mooresville
Regional Office 704-663-1699) as soon as possible but no later than 24 hours from the time the
permittee became aware of the bypass. Overflows and spills occurring outside normal business hours
may also be reported to the Division's Emergency Response personnel at 800-662-7956, 800-858-
0368, or 919-733-3300. A written report shall also be provided within five (5) days of the time of
the incident. The report shall contain a description of the bypass, and its cause; the period of the
bypass,including exact dates and times,and if the bypass has not been corrected,the anticipated time
it is expected to continue; and steps taken (or planned)to reduce, eliminate,
and prevent recurrence of similar events. Any spill that reaches surface waters (i.e. any spill that
reaches any water already present in a conveyance, stream, ditch, etc...) or any spill greater than
1,000 gallons on the ground that does not reach surface waters must be reported.
An adequate spill response for those spills reaching surface waters should include an
evaluation downstream of the point at which the spill entered surface waters to determine if a fish
kill occurred. The evaluation should also include the collection of upstream dissolved oxygen and
pH measurements for background information and dissolved oxygen and pH measurements at
multiple points downstream of the entry point to document any negative impact. Failure to report
the bypass of collection system,pumping station or treatment facility subjects violators to penalties
of up to $25,000.00 per day per violation.

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 • a a

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or"the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act, as amended,33 USC
1251,et.seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured,divided by the number of daily discharges sampled and/or measured during such
month. It is therefore,an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as"Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week(Sunday-Saturday) on which daily discharges are
sampled and measured,divided by the number of daily discharges sampled and/or measured
during such week. it is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as"Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum,"in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is,therefore,an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as"Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum"under'Other Limits"in Part 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.

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

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.

3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system,which is not a designed or established or operating
mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable,or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which-does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c.and d.of this section.
c. Notice
(I) 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
(I) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass,unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of •
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C)The permittee submitted notices as required under Paragraph c.of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (I) of this section.

Part II

5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed,contemporaneous operating logs,or other relevant evidence that:
(1)An upset occurred and that the permittee can identify the cause(s)of the upset;
(2)The permittee facility was at the time being properly operated; and
(3)The permittee submitted notice of the upset as required in Part II,E.6. (b)(B) of this permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
Solids,sludges,filter backwash,or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such
as to prevent any pollutant from such materials from entering waters of the State or navigable
waters of the United States. The permittee shall comply with all existing federal 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.

PERMIT:
The permitted facility is a 0.012 MGD wastewater treatment system consisting of dual
septic tanks, dosing tank, dual surface sand filters, recirculating pump station, dual UV
disinfection, and continuous flow recording device.
The permit for this facility became effective on 5/1/98 and expired on 2/29/00. The
Division has received the appropriate documentation for the permit renewal. The facility is
operating under the limits and requirements of the previous permit until issuance of the new
permit.
RECORDS AND REPORTS:
Records reviewed during the inspection included the calibration log and the Operator-
in-Responsible Charge (ORC) log. No deficiencies were found.
FACILITY SITE REVIEW/OPERATIONS & MAINTENANCE:
The facility utilizes two septic tanks (6,000 gallon, 12,000 gallon) that are operated in
series, a 20ft. x 10 ft. dosing tank with dual siphons, dual 2048 sq. ft. surface sand filter beds
covered with gravel, a recirculating pump station with dual recirculation and dual discharge
pumps, and dual UV disinfection units. The facility appeared to be properly operated and
maintained. No vegetation was detected on the sand filter beds. The ORC was very
knowledgeable of the treatment processes and equipment used at the facility.
The facility is staffed with one Grade IV ORC. A certified back-up operator has been
designated and is available when the ORC is unable to visit the facility.
LABORATORY:
Water Tech Labs, Inc., (Certification#50) in Granite Falls, North Carolina has been
contracted to provide analytical support. The lab was not evaluated during this inspection.
The ORC performs the on-site tests for pH and TRC under the Water Tech Labs, Inc.
laboratory certification.
EFFLUENT/RECEIVING STREAM:
The facility discharges into Ore Branch, which is a Class C water in the Catawba River
Basin. The effluent was clear with no suspended solids or foam. The receiving stream did not
appear to be negatively impacted. The discharge outfall was well maintained and accessible at
the time of the inspection.

Pumpkin Center Elementary and Middle School WWTP

SELF-MONITORING PROGRAM:
The facility began discharging in late October 1999. Self-monitoring reports were
reviewed for the period October 1999 through March 2000, inclusive. No limit violations were
reported. All monitoring frequencies are being performed in accordance with permit
requirements. The required 10-day interval between the collection of samples for effluent
ammonia was not adhered to for December 1999.
FLOW MEASUREMENT:
Effluent flow is measured continuously by a magnetic flow meter with totalizer and
chart recording. The flow meter was calibrated (when installed) by Johnston, Inc. of Indian
Trail, N.C. on 6/4/99. The ORC indicated that the flow meter would be calibrated on an
annual basis.
SLUDGE DISPOSAL:
Septage is removed as needed by Robert's Septic Tank Service, Inc., of Maiden, NC.
Final disposal is at the City of Newton Clarks Creek WWTP.
SEWER OVERFLOW:
Please be advised that pursuant to Part II, Section E of your NPDES permit, and North
Carolina Administrative Code (NCAC) 15A 2B .0506 (a)(2), any failure of a collection sewer,
pumping station or treatment facility resulting in a bypass without treatment of all or any
portion of the wastewater shall be reported to the central office or the appropriate regional
office (Mooresville Regional Office 704-663-1699) as soon as possible but no later than 24
hours from the time the permittee became aware of the bypass. Spills occurring on weekends
or holidays can be reported by calling the North Carolina Division of Emergency Management
at 919-733-3300. A written report shall also be provided within five (5) days of the time of the
incident. The report shall contain a description of the bypass, and its cause; the period of the
bypass, including exact dates and times, and if the bypass has not been corrected, the
anticipated time it is expected to continue; and steps taken (or planned) to reduce, eliminate,
and prevent recurrence of similar events. Any spill that reaches surface waters (i.e. any spill
that reaches any water already present in a conveyance, stream, ditch, etc...) or any spill
greater than 1,000 gallons on the ground that does not reach surface waters must be reported.
An adequate spill response for those spills reaching surface waters should include an
evaluation downstream of the point at which the spill entered surface waters to determine if a
fish kill occurred. The evaluation should also include the collection of upstream dissolved
oxygen and pH measurements for background information and dissolved oxygen and pH
measurements at multiple points downstream of the entry point to document any negative
impact. Failure to report the bypass of collection system, pumping station or treatment facility
subjects violators to penalties of up to $25,000.00 per day per violation.

Mr. Seagle, the NPDES Unit received the permit renewal application for SEP _t 5 1999
the Pumpkin Center Elementary School on September 1, 1999. Thanks for
submitting this package in a timely fashion.
itmI +dll
I'm sorry to inform you that the NPDES Unit has five vacant positions i
(out of a total of 13). This staff shortage is delaying all of our
permit renewals. Our remaining staff are currently reviewing
Authorizations to Construct, speculative limit requests, major permit
modifications and
201 plans 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 NC0086185, the existing
requirements in that permit will remain in effect until the permit is
renewed (or other action is taken by the Division). We appreciate your
patience and understanding as we operate with a depleted staff.
If you have any questions about your permit (or the permit renewal
process in general), simply reply to this e-mail.

Subject:Renewal of NPDES Permit NC0086185
Pumpkin Center Elementary School
LINCOLN County
Dear Permittee:
The subject permit expires on February 29, 2000. 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.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no
later than September 2, 1999. Failure to request renewal of the permit by this date will result in a civil
assessment of at least$250.00. Larger penalties may be assessed depending upon the delinquency of
the request.
If any wastewater discharge will occur after September 2, 1999 (or if continuation of the permit
is desired), the current permit must be renewed. Operation of wastewater treatment works or
continuation of discharge after September 2, 1999 would violate North Carolina General Statute 143-
215.1 and could result in assessment of civil penalties of up to $10,000 per day.
If all wastewater discharge has ceased at your facility and you wish to rescind this permit,
contact Robert Farmer of the Division's Compliance Enforcement Unit at [phone], extension
531. 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 below.
Sincerely,
Charles H. Weaver, Jr.

The following items are REQUIRED for all renewal packages:
❑ A cover letter requesting renewal of the permit and documenting any changes at the facility since
issuance of the last permit. Submit one signed original and two copies.
❑ The completed application form (copy attached), signed by the permittee or an Authorized
Representative. Submit one signed original and two copies.
❑ If an Authorized Representative (see Part II.B.11.b of the existing NPDES permit) prepares the
renewal package, written documentation must be provided showing the authority delegated to the
Authorized Representative.
❑ A narrative description of the sludge management plan for the facility. Describe how sludge (or
other solids) generated during wastewater treatment are handled and disposed. If your facility has no
such plan (or the permitted facility does not generate any solids), explain this in writing. Submit one
signed original and two copies.
The following items must be submitted ONLY by Industrial facilities which discharge
process wastewater:
❑ Submit the last 3 years' production data for the facility. Use units consistent with those required for
reporting to EPA.
❑ Industrial facilities classified as Primary Industries (see Appendix A to Title 40 of the Code of
Federal Regulations, Part 122) must submit a Priority Pollutant Analysis (PPA) in accordance with
40 CFR Part 122.21. If the PPA is not completed within one week of September 2, 1999, submit the
application package without the PPA. Submit the PPA as soon as possible after September 2, 1999.
The above requirements do NOT apply to municipal or non-industrial facilities.
PLEASE NOTE:
Due to a change in fees effective January 1, 1999, there is no renewal fee required with
your application package.
Send the completed renewal package to:

Dear Mr. Seagle:
In accordance with North Carolina General Statute § 90A-37, the Water Pollution Control
System Operators Certification Commission is required to classify all water pollution
control systems. The Rating Scale for classification of wastewater treatment facilities,
found at 15A NCAC 8C .0002, was adopted by the Commission to classify water pollution
control systems. The classification of a facility is determined by definition or by the total
number of points for all components of the treatment process.
The Water Pollution Control System Operators Certification Commission has determined
that the subject facility is classified as a Grade 1 Wastewater Treatment Plant.
As required by 15A NCAC 8A .0202 and your permit, you must designate a Grade 1 or
higher Operator in Responsible Charge (ORC) and a Back Up Operator with at least a
Grade 1 cert., ; once construction is 50% complete. Please submit to this office by
February Il., 1998 a projected date when the facility will be 50% complete. Failure to
designate a ►ro!- * certified operator and back-up operator constitutes a violation of the
permit issue. or thi• facility.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or "the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251,et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.
•

Part II
Page 2 of 14
•
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily .
average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June,July through September,and October through December.

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.

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

Dear Mr. Seagle:
The Permits and Engineering Unit has completed a preliminary engineering review of the above referenced application. The
following items must be addressed before we can complete our review:
• How will the facility be operated? What are the recirculation ratios? What are the dosing times?
• There must be pump duality in the pumping station to ensure reliability. The pumping station volume must be large enough to handle
the flow from the dosing tank if there is a power failure. Please submit calculations to verify this. The dosing tank should also be
sized large enough to handle one day's flow.
• Is the recirculation wetwell a.k.a.the effluent pumping station? If so, what is the elevation of the invert in? It is listed as 54.40 and
as 52.50 on the plans.
• Please include details of the UV disinfection system on the plans. The unit must be able to treat wastewater with a fecal coliform
count of 200 colonies/ml. What does the unit of 200/1000 m/MPN stand for? Spare bulbs/parts should be kept onsite. There must be
two channels for duality.
• The sand filter must have a liner. The effective size of the sand should be in the range of 1.0 to 5.0 mm with a uniformity coefficient
of<2.5%. Is the underdrain 4"or 6"? Both are indicated on p.5 of the plans. Is there freeze protection for exposed piping?
• Submit manufactures specifications for all units.
Refer to the subject permit application number when providing the requested information. Please submit three copies of all
information to my attention at the address below. Also, please note that failure to provide this additional information on or before
October 19 will subject your application to being returned as incomplete,in accordance with 15A NCAC 2H.0208(e).
If you have any questions on this matter,please call me at 919/733-5083,extension 518.

Dear Mr. Seagle:
Our records indicate that NPDES Permit No. NC0086185 was issued on March
30, 1998 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/are 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
ti ,-4 reporting forms furnished or approved by this Agency. If you have not received these
a — 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
a (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.
k "* ., Please be advised that an annual administering and compliance monitoring fee
"' "'"--- r..•_ may be required for your facility. You will soon be receiving a statement from our
...v......as 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.

requirements for a certified wastewater treatment plant operator if you are operating
wastewater treatment facilities. Any changes in operation of wastewater treatment
facilities, quantity and type of wastewater being treated or discharged, expansions and/or
upgrading of wastewater treatment facilities must be permitted or approved by this
Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects
the Permittee to enforcement action pursuant to Section 143-215.6 of the North Carolina
General Statutes. A civil penalty of up to $10,000 per violation (and/or criminal
penalties)may be assessed for such violations. If you find at any time that you are unable
to comply with the terms and conditions of the Permit, you should contact this Office
immediately. A Consent Order may be necessary while pursuing action to obtain
compliance.
As a final note, an NPDES Permit is normally issued for a five-year period.
Permits are not automatically renewed. Renewal requests must be submitted to this
Agency no later than 180 days prior to expiration. Please make note of the expiration
date of your Permit. This date is set forth on Page 1 of the Permit. Also note that
NPDES Permits are not automatically transferable. If you, as the Permittee, cease to
need this Permit, then you should request that the Permit be rescinded or transferred to
another party, if necessary.
As mentioned previously, the purpose of this letter is to advise you of the
importance of your NPDES Permit. Please read the Permit and contact this Office at
704/663-1699 in Mooresville if you have any questions or need clarification. We look
forward to providing any assistance.

project . It is our opinion that a standby disinfection system with
chlorination/dechlorination be provided to safeguard public health,
as the ultraviolet disinfection system is not always effective
during wet weather.
Pending final review and approval by the SERG, it is
recommended that an Authorization to Construct be issued to the
applicant .

PUMPKIN CENTER SCHOOL

D&D PROJECT NO. C7031
Dear Mr.Pellei:
Attached please find the revised plans and specifications for the above project. The following —�
items are in response to the letter from your office dated September 18, 1998:
1) The facility will be operated by electrical service provided by Owner under separate contract.
In the event of power failure,the facility will be powered by the school's back-up generator;
the recirculation ratios are 1/3 effluent, 2/3 recirculation; the dosing time is 17 minutes.
2) The facility has been revised to accommodate pump duality. The pumping station volume and
the storage in the sand filter bed is approximately 24,800 gallons; the capacity of the dosing
tank is 7,480 gallons. Therefore,the storage provided by the recirculation wetwell and the
sand filter bed is more than sufficient to handle the flow from the dosing tank. Further,the
dosing tank is sized to hold 75% of the average daily flow.
3) The recirculation wetwell is the same as the effluent pumping station. The inverts on the plans
have been revised and are consistent.
4) Sheet 6of6 has been added to the drawing set to include the UV Disinfection Unit details. The
UV unit will treat the wastewater to a fecal coliform count of 200 colonies/ml. Since the UV
unit is designed with two (2)lamp racks, duality is accomplished with one single unit. Should
the occasion arise where one of the racks fails,the flow can be converted solely to the other
rack while maintenance replaces the faulty rack. Spare racks and bulbs will be kept on site for
use in emergency situations.
5) The revised plans show a PVC liner for the sand filter. The underdrain size is 6-inch and is
consistent throughout the plans. As for freeze protection, any exposed pipe will be within the
walls of the shed housing the UV unit.
6) Manufacturer specifications for the UV unit, the effluent pumps, and the recurculation pumps
are included with this submittal. Also, specifications for the dosing siphon are included for
your reference.
7) If the sand filter bed became inoperable and in need of repair,the dosing siphons could be
plugged, trapping the wastewater in the septic tanks and the dosing tank. Until the problem
could be fixed, the tanks could be pumped daily using a pump ruck.

Contractor at his expense.
3.02 EMBANKMENTS, FILLS AND BACKFILLS
(a) GENERAL
After areas have been stripped of topsoil, and before embankments and fills are
started, all areas to receive fill shall be scarified by use of harrows, scarifiers or
other approved means for a minimum depth of 6-inches. Select material from the
site shall be placed on scarified areas and tamped with sheeps foot rollers. Should
any area be unsatisfactory as a foundation for the embankment or fill,the Contractor
shall remove the unsuitable material and replace with select material.
Embankments and fills shall be constructed at the locations and to the lines and
grades indicated on the Drawings. The completed fill shall correspond to the shapes
and sizes of the typical cross sections or contours as shown on the Drawings.
Material shall be placed in horizontal layers 8 to 12-inches in loose depth and
thoroughly compacted prior to placing each following layer. All fill material shall be
free from roots or other organic material, trash, and from all stones having any one

Contractor after backfilling the trench. All material, equipment, pumps, including gages, and
labor required to conduct the tests shall be furnished by the Contractor. Tests shall be
conducted in accordance to AWWA C600 as modified herein. It is the intent of this
Specification that all joints in the water line shall be watertight and that all leaks which are
found either by observation or any specified test shall be made watertight by the Contractor,
regardless of the amount of leakage.
All joints in exposed piping, regardless of location, shall be tight and drip free at all
operating pressures. Water for the tests shall be taken from the system when available.
Cross-connections will not be allowed. Where any section of a water line is provided with
concrete reaction backing for fittings or hydrants, the hydrostatic pressure test shall not be
made until at least five (5) days after the installation of the concrete reaction blocking. All
air shall be expelled from pipe, valves and hydrants.
Hydrostatic test pressures shall be fifty percent (50%) above normal working pressure,
based on the elevation of the lowest point in the line or section being tested and corrected
to the elevation of the test gage. Test pressure shall not vary more than 5 PSI plus or
minus during the test.
The leakage test shall be set at the maximum working pressure but not less 100 PSI
corrected to the elevation of the test gage. The amount of water added to maintain
pressure shall be measured.
(a) PRESSURE TESTS
The newly laid water line or any valved section of piping shall be continuously
subjected for four (4) hours to a hydrostatic pressure test as indicated above.
Pressure tests shall not be conducted on pipe line sections over one (1) mile in
length. Each valve shall be opened and closed several times during the test.
Exposed pipe, joints, fittings, valves, and hydrants shall be carefully examined
during the test. Joints showing visible leakage shall be replaced or remade as
02600-5 C7031

necessary. Leaking rubber-gasketed joints shall be remade, using new gaskets if
necessary. Cracked or defective pipe, mechanical joints, fittings, valves, or
hydrants discovered in consequence of this pressure test shall be removed and
replaced with sound material, and the test shall be repeated until the test results are
satisfactory.
(b) LEAKAGE TEST
The leakage test may be conducted concurrently with the pressure test. However,
the duration of each leakage and pressure test shall be at least a total of 8 hours
and during the test, the main shall be subjected to the test pressures of at least 100
PSI. Leakage is defined as the quantity of water that must be supplied into the
newly laid water line, or any valved section thereof, necessary to maintain the
pressure within 5 PSI of the specified pressure for the duration of the test. No
piping installation will be accepted until the leakage is less than the number of
gallons per hour as determined by the formula:
DUCTILE IRON PIPE (DIP) POLYVINYL CHLORIDE(PVC)
L = SD / P L= ND/ P
133,200 7,400
In which L equals the allowable leakage in gallons per hour; S is the length of pipe
line tested, in feet; N is the number of joints in length of pipeline tested; D is the
nominal diameter of the pipe, in inches; and P is the average test pressure during
the leakage test, in pounds per square inch gauge.
Should any test of water line laid disclose leakage greater than that indicated in
Table 6 of AWWA C600, the defective joints shall be located and repaired until the
leakage is within the specified allowance, and all visible leaks have been eliminated
without additional cost to the Owner.

All water lines for the distribution of potable water shall be thoroughly flushed to
remove all mud, dirt, and debris. A blow off, a corporation stop or a fire hydrant
shall be installed at the end of the line to release entrapped air when the lines are
02600-6 C7031

filled with chlorinated water from the opposite end. The chlorine shall be injected
into the new pipe system by means of a pump as water is slowly introduced into the
pipe system from the existing water distribution system, the disinfected well or from
other potable sources. The chlorinated water shall have a minimum available
chlorine concentration of 50 PPM. After filling the new lines with chlorinated water,
they shall be valved off and the chlorinated water allowed to remain in the lines for
twenty-four (24) hours. At the end of this period, the chlorine residual shall be at
least 10 PPM. The lines should then be thoroughly flushed until there is only a
normal chlorine residual present, as determined by the orthotolidine test. Several
samples of water shall be collected from various spigots, not from hydrants, along
the line for bacteriological analysis by a certified laboratory. If satisfactory
bacteriological results are obtained, the lines may then be placed in service.
At Contractor's option, pressure and leakage tests may be conducted during the
disinfection process. All makeup water for these tests shall contain 50 PPM of
chlorine. Should the pressure or leakage test fail, the disinfection process shall be
repeated in its entirety.
3.09 MEASUREMENTS

covering of any type is applied.
3.09 PATCHING AND FINISHING CONCRETE WORK
After removing the forms, any concrete which is not formed as shown on plans or for any
reason is out of alignment or is not plumb and level or shows defective surfaces due to
improperly filled honeycombing, wood debris on surface, or that does not conform with the
intent of these Specifications shall be removed and replaced at the Contractor's expense.
Immediately after removing the forms, all tie holes shall be filled solid with mortar after first
being thoroughly wetted.
Defective areas shall be chipped away to a depth of not less than 1-inch, with edges
perpendicular to the surface. The area to be patched and a space at least 6-inches wide
entirely surrounding it shall be wetted. After wetting, area shall be brushed with a mixture
of one part sand and one part Portland cement, and sufficient water to produce a paintlike
material, followed immediately with mortar consisting of one part cement, three parts sand,
and enough water to permit compaction. The mortar shall be packed tightly and screeded
off slightly higher than the surrounding surface. After one or two hours, the area shall be
leveled and finished to match the adjoining concrete and kept moist twenty-four(24) hours.

and other imperfections, other than air holes from plywood forms. In the event that
efflorescence, stains, oil, grease of any unsightly accumulations of foreign materials are
visible on the exposed surfaces of finished concrete, the surface shall be scrubbed with
detergents and thoroughly rinsed with water.
After discoloration is removed, surfaces will be dry rubbed until all surfaces are of uniform
color. The grouting of the air holes shall be accomplished by mixing one part cement and
one and one-half parts fine sand with enough water to produce a thick paste. White
Portland cement shall be used for all or part of the cement to give the color desired. Wet
the surface thoroughly and apply the grout with brushes. Float the grout vigorously at same
time. As soon as the grout begins to set, rub off all excess grout with sponge rubber floats,
leaving no film on the surface. (This last operation shall be timed such that grout will not
be rolled out of the air pockets and depressions). Next, allow surface to dry thoroughly,
then rub it vigorously with dry burlap. There shall be no visible film after this rubbing. No
grouting will be done when temperature is below 60 degrees F.
The exposed surfaces requiring rubbing shall result in a pleasant finish. Exposed surfaces
shall be rubbed a minimum of 12-inches below the finished grade or 12-inches below the

Dear Mr. Seagle:
The Division has completed its preliminary technical and regulatory review of the
NPDES permit application for the above referenced facility and issuance of a permit
appears favorable at this time.
Please realize, however, that until the technical review has been completed and until
the Division's intent to issue has been published for the purpose of receiving public
comment, no assurance of permit issuance can be made. Should unforseen technical or
regulatory issues arise, or if public comment to the proposed discharge is significant, the
Division may be inclined to deny issuance of the NPDES permit.
If you have any questions or concerns regarding this permit application, please
m contact Mr. Mark McIntire of my staff at(919) 733-5083, extension 553.
Sincerely,

Do you know if your office ever received this acknowledgement letter / SR
request? With the mail situation what it has been lately, I have a sinking
feeling than you didn't. Anyway, it needs a staff report. I am going to
proceed with the public notice as the modeling has been completed.
Let me know if you haven't received a copy of the application and I'll send
another copy.
