Subject: NPDES Permit No. NCO029742
Iredell Correctional Center
Iredell County, NC
Dear Mr. Stovall:
Our records indicate that NPDES Permit No. NCO029742 was issued on June 21, 2004 for
the discharge of wastewater to the surface waters of the State from your facility. The purpose of this
letter is to advise you of the importance of the Permit and the liabilities in the event of failure to
comply with the terms and conditions of the Permit. If you have not already done so, it is suggested
that you thoroughly read the Permit. Of particular importance is. Page 4.
Page 4 sets forth the effluent limitations and monitoring requirements for your discharge.
Your discharge must not exceed any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types.and sampling locations. Upon
commencement of your discharge (or operation), you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or approved by this Agency. If you
have not received these forms, they should be arriving shortly. If you fail to receive the forms, please
contact this Office as quickly as possible. I have enclosed a sample of the "Effluent" reporting form
(DWQ 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 $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.

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 Da
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 6/20/2003

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 612012003

NPDES Permit Requirements

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.

Subject: Draft NPDES Permit
Permit NCO029742
Iredell Correctional Center
Iredell County
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully
to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from your current permit:
• . A daily maximum total residual chlorine (TRC) limit has been added to the permit. See the attached total
residual chlorine policy memo for details. The facility is allowed 18 month from the effective date of the
permit to comply with the total residual chlorine limit. This time period is allowed in order for the facility to
budget and design/construct the dechlorination and /or alternative disinfection systems.
• The daily maximum limit for NH3-N has been added to the permit. Based on adverse comments from EPA,
the Division of Water Quality was required to implement daily maximum NH3-N (ammonia) limits for non -
municipal facilities, as required by the Code of Federal Regulations. This implementation policy was adopted
October 15, 2002. The daily maximum value is five times the monthly average value (this multiplier was
established based on a review of treatment capability at various non -municipal plants). Daily maximum
values are capped at 35 mg/L. This permit includes both monthly average and daily maximum limits for
NH3-N.
Please submit any comments to me no later than thirty days following your receipt of the draft. Comments should be
sent to the address listed at the bottom of the previous page. If no adverse comments are received from the public or
from you, this permit will likely be issued in late June, with an effective date of August 1, 2004.
If you have any questions or comments concerning this draft permit, contact me at the telephone number or

SUBJECT: Total Residual Chlorine Policy for NPDES permits
Alan W. Klimek, P.E., Director
Division of Water Quality
Every three years the State is required by the Clean Water Act to review its surface water quality standards and
classifications, determine if changes are needed and to make any necessary changes. This review process is referred to
as the "triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface
water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before
the state's Environmental Management Commission on October 10, 2002.
The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic, Cyanide,
Methylene Blue Active Substances (MBAS) and Total Residual Chlorine (TRC). The Hearing Officer also
recommended the addition of a standard for Methyl Tert-Butyl Ether (MTBE).
All of the Hearing Officer's proposed changes were adopted with the exception of MTBE. The changes took effect -
on April 1, 2003. This memo documents the changes to the NPDES permitting policy for TRC limits.
Total Residual Chlorine (TRC)
Previously, TRC- had an Action Level Standard, except in designated Trout waters. The Triennial Review changes
modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/L The Aquatic Life Standard will
remain for designated Trout waters.
Aquatic life Standard —17 µg/L (freshwater only)
Trout Waters —17 µg/L
Revised TRC Policy
➢ TRC limits will be assigned to permit renewals and all new permits issued after April 1, 2003.
➢ Facilities that do not use chlorine will not receive a TRC limit; however, the presence of a chlorine back-up
system to augment UV or other disinfection requites a TRC limit.
➢ Facilities discharging to streams with a 7Q10 <0.05 cfs (zero -flow streams) will receive a limit of 17 µg/L.
➢ Limits will be capped at 28 µg/L to protect against acute impacts.
Itis likely that many facilities will need to add dechlorination (or use another means of disinfection) to comply with
the new TRC standard. Therefore, a compliance schedule of 18 months from the effective date of the permit may
be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the
facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES
Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NCO029742
Summary
The facility has requested a permit renewal with no modifications. It is recommended
that the permit be renewed as drafted. The facility has been inactive for a few years
since the housing of prisoners at this location has been suspended indefinitely. The
facility discharges into dry ditch, the "ditch" was designated in the previous permit as an
effluent conveyance and was not subject to zero flow limits.
The following notes were taken during the review of the application package:
• 303(d) List Review: Fifth Creek is not listed on the North Carolina 303d
List.
Review of Basin Plan: No information was reported for Fifth Creek in the
Basin Plan.
Staff Report (most recent dated March 29, 2004): Facility is permitted to
discharge 0.0235 MGD in an UT to Fifth Creek. Solids from the package
plant are digested aerobically, thickened, and periodically pumped and
hauled to the Statesville Third Creek WWTP. Solids are ultimately disposed
of by land application. Facility is classified as a class H facility. Report
recommends renewal of the permit.
• DMR Review:
The facility has a good compliance record. During the previous permit cycle only
two NOVs were issued for fecal Coliform violation in 1999 and 2000.

a. Classification: C -
b. River Basin and Subbasin No.: Yadkin 030706
c., Describe receiving stream features and pertinent downstream uses: The discharge
enters a small, UT that flows about 200 feet before it becomes dammed by
beavers just prior to its confluence with the main segment of Fifth Creek. At this
point a large freshwater marsh has formed The UT and marsh are both on
NCDOC property. The marsh does offer additional treatment of the effluent prior
to entering the main segment of Fifth Creek. The effluent limits contained in the
current permit have been promulgated for a discharge directly to Fifth Creek.
PART H - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater: 0.0235 MGD (Design Capacity)
b. What is the current permitted capacity: 0.0235 MGD
C. Actual treatment capacity of current facility (current design capacity): 0.0235
MGD
d. Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: There have been no ATCs issued in the past two years.
e. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of a bar screen followed by a comminutor, two
equalization basins, two aeration basins, a clarifier, two surface sand filters (only
,one is operational), an aerated sludge holding tank, and a chlorine contact
chamber.
f. Description of proposed WWT facilities: There are no WWT facilities proposed
at this time.
g. Possible toxic impacts to surface waters: Chlorine is the product that has been
used in the past for disinfection purposes. If this facility is reactivated, then
dechlorination will most likely be necessary.
h. Pretreatment Program (POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: When this facility was in operation,
residuals were removed as needed and hauled to the City of Statesville's Third Creek
WWTP.
3. Treatment plant classification: Class H (no change from previous rating).
4. SIC Code(s): 9223 Wastewater Code(s): 11 MTU Code(s): 06007

Page Three
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant Funds or are any public monies
involved (municipals only)? Public monies were used in the construction of this facility.
2. Special monitoring or limitations (including toxicity) requests: None at this time.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4. Alternative analysis evaluation
a. Spray Irrigation: Insufficient area available either on the existing site or on nearby
properties to accommodate the design flow. Soils on the site are also not suitable
for the irrigation of wastewater. It has been estimated by the permittee's engineer
that up to 18 acres of land may be necessary to handle the currently permitted
flow. This amount of land is not available in the immediate area of the prison.
b. Connect to regional sewer system: The nearest municipal sewer collection system
is = 2.5 miles from the site. Preliminary cost estimates developed by Willis
Engineers in 1999 indicate that it will be cost prohibitive to pursue this option.
C. Subsurface: See spray irrigation comments above.
d. Other disposal options: Another possible disposal option that has been considered
is a connection to the nearby Statesville Auto Auction WWTP (SAAWWTP).
The SAAWWTP is a 0.012 MGD WWT facility that discharges to Fifth Creek.
The effluent from the prison would have to be pumped = 1.5 miles in order to
access the SAAWWTP. If this option is to be explored, the SAAWWTP would
have to be.expanded from its present capacity, and contractual agreements would
have to be developed between the Auto Auction and the NCDOC. Should the
NCDOC ever reactivate the subject prison, this option should receive further
consideration.
PART IV - EVALUATION AND RECOMMENDATIONS
The NCDOC has requested that the subject NPDES Permit be renewed even though the
housing of prisoners at this location has been suspended indefinitely. The existing WWT facility
has been mothballed until such time as prison operations resume. The employees in the adjacent
NCDOT Operations Building that share the property with the NCDOC are served by a small
septic tank system.
If the existing WWT facility is ever reactivated, extensive work will be needed to get the
WWTP in operational condition. The existing tankage is approaching the end of its design life
with considerable evidence of corrosion on the interior and exterior tank walls and interior
baffles. Additional treatment components (such as dechlorination) may also be necessary to
comply with anticipated reissued permit limits.

Page Four
Pending receipt and approval of the draft permit, it is recommended that the permit be
reissued as requested. It should not be necessary to include a construction compliance schedule
in the renewed permit (for any necessary WWTP upgrades) since this facility is not currently in
operation. -,The NCDOC commissioned an engineering study in 1999 that detailed the various
wastewater disposal options that were available. This study should be updated prior to the
NCDOC reactivating the existing WWT system.

Dear Mr. Stovall:
DIVISION OF WATER QUALITY
October 19, 2000
NPDES Permit No. NCO029742
Iredell Correctional Center
Iredell County, NC
Our records indicate that NPDES Permit No. NCO029742 was issued on October
9, 2000 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, 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 $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 I 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.

PART U.
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 1I 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.

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
(D.
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.

OTHER REQUIREMENTS
A. Construction
No construction of wastewater treatment facilities or additions to add to the plant's treatment
capacity or to change the type of process utilized at the treatment plant shall be begun until Final
Plans and Specifications have been submitted to the Division of Water Quality and written approval
and Authorization to Construct has been issued.
B. Groundwater Monitoring
The permittee shall, upon written notice from the Director of the Division of Water Quality, conduct
groundwater monitoring as may be required to determine the compliance of this NPDES permitted
facility with the current groundwater standards.
C. Changes in Discharges of Toxic Substances
The permittee shall notify the Permit Issuing Authority as soon as it knows or has reason to believe:
a.That any activity has occurred or will occur which would result in the discharge, on a routine or
frequent basis, of any toxic pollutant which is not limited in the permit, if that discharge will
exceed the highest of the following "notification levels';
(1) One hundred micrograms per liter (100 ug/1);
(2)Two hundred micrograms per liter (200 ug/1) for acrolein and acrylonitrile; five hundred
micrograms per liter (500 ug/I) for 2.4-dinitrophenol and for 2-methyl-4.6-dinitrophenol; and
one milligram per liter (1 mg/1) for antimony;
(3) Five (5) times- the maximum concentration value reported for that pollutant in the permit
application.
b. That any activity has occurred or will occur which would result in any discharge, on a non -routine
or infrequent basis, of a toxic pollutant which is not limited in the permit, if that discharge will
exceed the highest of the following "notification levels';
(1) Five hundred micrograms per liter (500 ug/1);
(2) One milligram per liter (1 mg/1) for antimony;
(3) Ten (10) times the maximum concentration value reported for that pollutant in the permit
application.
D. Requirement to Continually Evaluate Alternatives to Wastewater Discharges
The permittee shall continually evaluate all wastewater disposal alternatives and pursue the most
environmentally sound alternative of the reasonably cost effective alternatives. If the facility is in
substantial non-compliance with the terms and conditions of the NPDES permit or governing rules,
regulations or laws, the permittee shall submit a report in such form and detail as required by the
Division evaluating these alternatives and a plan of action within sixty (60) days of notification by the
Division.

Subject: Renewal of NPDES Permit NCO029742
Iredell Correctional Center
Iredell County .
Dear Permittee:
The subject permit expires on July 31, 1999. North Carolina General Stature 143.215.1(c) requires that an
application for permit renewal be filed at least 180 days prior to the expiration date.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than February 1,
1999. Failure to request renewal by February 1, 1999 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 July 31, 1999 (or if continuation of the permit is desired), the permit must
not be allowed to expire. Operation of waste treatment works or continuation of a discharge after July 31, 1999
would violate NCGS 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 the subject 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 which you must
submit when applying for renewal of the subject permit.
If you have any questions, please contact me. My telephone number, fax number and e-mail address are listed below.

The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33
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 Pan 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 Pan 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 Pan I of the permit.

Part II
Page 2 of 14
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.
I
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is.
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

Part II
Page 3 of 1.4
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.
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 gmai ter\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.
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, value_ s of zero (0) shall be
considered to be one (I).

Part 19
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, -any consecutive 24-hour period that reasonably
represents the calendar day may be used for sampling.
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act
•ly• t ►1 .c •s•►l9VVIf) ►
The permittee must comply with all conditions of this permit. Any permit noncompliance
constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit
termination, revocation and reissuance, or modification; or denial of a permit renewal
application.
a. The permittee shall comply with effluent standards or prohibitions established under
section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage
sludge use or disposal established under section 405(d) of the Clean Water Act within the
time provided in the regulations that establish these standards or prohibitions or standards
for sewage sludge use or disposal, even if the permit has not yet been modified to
incorporate the requirement.
b. The Clean Water Act provides that any person who violates a permit condition is subject to
a civil penalty not to exceed $25,000 per day for each violation. Any person who
negligently violates any permit condition is subject to criminal penalties of $2,500 to
$25,000 per day of violation, or imprisonment for not more than 1 year, or both. Any
person who knowingly violates permit conditions is subject to criminal penalties of $5,000
to $50,000 per day of violation, or imprisonment for not more than 3 years, or both. Also,
any person who violates a permit condition may be assessed an administrative penalty not
to exceed $10,000 per violation with the maximum amount not to exceed $125,000. [Ref. -
Section 309 of the Federal Act 33 U.S.C. 1319 and 40 CFR 122.41 (a)]
c. Under state law, a civil penalty of not more than ten thousand dollars ($10,000) per

The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This
provision requires the operation of back-up or auxiliary facilities or similar systems which are
installed by a permittee only when the operation is necessary to achieve compliance with the
conditions of the permit.
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.
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a'treatment
facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c . Notice
(1) Anticipated bypass. If the permittee knows in advance, of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part 11, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

Part II
Page 9 of 14
periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. Upsets
' a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset.shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this
permit.
(4) The permittee complied with any remedial measures required under Part II, B.-2. of this
permit.

PART IV.- EVALUATION AND RECOMMENDATIONS
The Permittee, North Carolina Department of Correction, is
requesting permit renewal for its domestic wastewater treatment

Lj
plant. An engineering report evaluating alternatives to
discharge was submitted with this permit renewal. The purpose of
the report -was to evaluate alternatives to discharge (since the
facility was thought to be discharging to a zero flow stream)..
Based on the engineering report, the recommendation was to
conduct a more thorough evaluation of the plant's condition and
to repair it as necessary in lieu of constructing a new facility.
The property located between the discharge point and Fifth Creek
is owned by t/he Department of Correction, and the existing ditch
is acting as a conveyance to Fifth Creek. Therefore, the plant
does not discharge to a zero flow stream and the new limits
should be revised to address this situation:
The sand filter located on the lower side of the WWTP must
be:repaired and the residue from the sand filters must be
disposed off in a proper manner.
It is recommended that the permit be renewed provided that
the above concerns have been addressed.

permits. I am returning the check you submitted with the permit application, along with
a revised fee schedule.
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.
If you have any additional questions concerning renewal of the subject permit,
please contact me at [phone], extension 511.
Sincerely,
qla,

EXECUTIVE. SUMMARY
This report is an engineering alternatives analysis that investigates potential
wastewater disposal methods to meet the needs of the Iredell Correctional Center.
This analysis was required as a condition of the NPDES permit for the facility issued
in September, 1994. Recommendations are included in this report for the most cost-
effective wastewater disposal option to comply with the revised effluent permit limits
that will be issued by the North Carolina Department of Environment, Health and
Natural Resource, Division of Water Quality upon renewal of the NPDES permit in
late 1999.
The Iredell Correctional Center is a medium security facility that houses
approximately 120 inmates. The prison is located 6.5 miles northeast of Statesville,
North Carolina, on US 21 in Iredell County. Wastewater generated from the prison
is treated by a 15-year old package plant rated for 23,500 gallons per day (gpd).
Currently, discharge is to a zero flow stream that drains into a low lying wetland area
adjacent to Fifth Creek. sD:ue to�organizati"o_na�IFchanges:_with'in the�Department_ of_�
��©rection,__fhe=future°of the..facilify is uncertain_
The existing package plant consists of a manual bar rack, comminutor, two
equalization basins, two aeration basins, a dual hopper clarifier, two sand.filters and
a chlorine contact reactor. Sludge digestion entails an aerated sludge holding tank.
At this time, the plant is maintained by one operator who holds a Class II license.
The structural integrity of the steel package plant is suspect. The visible portions of
the outer tank walls have severely corroded resulting in holes through the tank walls.
Furthermore, the interior baffle walls separating the treatment units are deteriorated.
The extent of the corrosion was not thoroughly investigated.
The current permit limits imposed on the facility will expire on July 31, 1999. More
stringent effluent limits are likely to be imposed on the facility. These are likely to be
5 mg/I BOD5, 30 mg/I TSS, 2.0 mg/I NH3-N and 17 µg/I chlorine residual. Plant
records indicate that the plant has the capacity to comply with the new limits with the
exception of the residual chlorine limit.
Various disposal methods were explored to address these new limits given the
condition of the existing plant. These included: connection to a publicly owned
treatment works; connection to a privately owned treatment works; land disposal;
reuse; upgrading existing disinfection system; and construction of a new plant.
Continued surface water discharge from the existing plant was deemed to be the
most cost-effective solution that would meet anticipated discharge limitations. With
a change in disinfection from chlorine to UV, the existing plant should continue to
meet its permit requirements. The Department of Correction should conduct a more
in-depth evaluation of the existing tankage at the plant to ascertain its remaining

service life. On the basis of that evaluation, it should plan to replace the
plant some time in the future, ponce -the long- er rm o el 6.0 Correctional_E

SECTION 1
INTRODUCTION
CURRENT SITUATION
The Iredell Correctional Center is a medium security facility located 6.5 miles
northeast of Statesville on US 21 in Iredell County. The Correctional Facility houses
120 prisoners. The prison is comprised of dormitories, cafeteria, laundry facility,
upholstery shop and a woodworking shop for building furniture. Liquid waste from
the first three sources is served by a package treatment facility located at the site,
while the waste generated at the woodworking facility and upholstery shop is sent to
an onsite septic system. The future status of the Correctional Center is somewhat
uncertain.
The existing package treatment plant is permitted f 235Q0_eg:allons per day (gpd)
and has been �ir� rverve icel for over 6 years,. The plant is located at the south end of
.the prison and discharges into a zero flow stream, which drains into a low lying
wetland area adjacent to Fifth Creek. Figure 1-1 shows the location of the
Correctional Facility in relation to Fifth Creek.
The package plant consists of a manual bar rack, comminutor, two equalization
basins, and two aeration basins followed by two secondary clarifiers. In addition, the
self-contained treatment unit includes an aerated sludge holding tank. Discharge
from the secondary treatment unit is sent to two sand beds for filtration. According
to the operator, only one sand bed is in service. From the sand beds, the filtered
effluent undergoes chlorination via chlorine tablets injected into the water.
Currently, the plant is permitted for an effluent discharge of 16 mg/I BOD5, 30 mg/I
TSS, 9.0 mg/I NH3-N and a Fecal Coliform count of 200 colonies/100 ml. According
to 1997 and 1998 effluent records, the plant has only violated the Fecal Coliform
requirement on two occasions.. Besides these two incidents, the plant's effluent
quality has been good given the variance in waste constituents experienced at the
plant. According to the operator, the treatment plant experiences occasional toxic
loads. These are attributed to pouring bleach and floor finishing products into
,drains.
At this time, the package plant is run by one operator with a Class II license. The
plant is operated five days per week. Therefore, there is no operator intervention on
weekends or holidays. According to the operator, the equipment appears to be in
satisfactory condition with no major mechanical problems. However, limited physical
inspection of the steel tankage revealed that the structure is approaching the end of
its design life. The tanks that comprise the package plant were corroded to the point
that holes were visible through the outer tank walls above the liquid level.

FUTURE SITUATION
The current NPDES permit for the Iredell Correctional Center will expire at midnight
on July 31, 1999. The new NPDES permit will likely require the plant to meet the
following limits: 5 mg/I BOD5, 30 mg/I TSS, 2.0 mg/I NH3-N and 17 µg/l chlorine.
The plant would continue to be rated for 23,500 gpd. A review of the plant records
indicates that the plant has the ability to comply with the new permit with the
exception of the chlorine residual. To comply with the chlorine requirement, a
dechlorination system is required. In addition, the tanks that comprise the treatment
plant appear to be at the end of their intended design life as indicated by the
corrosion in Figures 1-2 and 1-3. Therefore, in -place abandonment of the existing
package is recommended.
The North Carolina Department of Environment and Natural Resources (NCDENR)
Division of Water Quality has recommended the evaluation of alternatives which will
eliminate the Iredell Correction Center as a point source. This report evaluates the
following alternatives to determine the most environmentally sound and cost-
effective solution for the Iredell Correctional Center:
• Construction of a new plant
• Upgrading Existing disinfection system
• Connection to a Publicly Owned Treatment Works (POTW)
• Connection to a privately owned treatment works
• Land based disposal alternatives
• Wastewater Reuse

SECTION 2
ANALYSIS OF ALTERNATIVES
CONSTRUCTION OF A NEW PLANT
This alternative entails the installation of a new package plant rated for 23,500 gpd.
The new system, complete with tertiary filtration and UV disinfection, would be
installed adjacent to the existing plant. See Figure 2-1 for proposed site location,
which is adjacent and to the .right of the existing system. The.' plant would have an
overall footprint of 56 feet by 12 feet (length by width). Space for the new -plant is
available at the existing site.
Figure 2-1: Proposed Site Location
No specific data was available for establishing influent design concentrations.
Published literature and influent characteristics from other prisons were consulted to
- determine appropriate influent pollutant concentrations. These values, provided in
Table 2-1, were used to establish influent design criteria.

The proposed package plant would include a manual bar screen followed by a 7,050
gallon aerated equalization basin to account for the diurnal variations in loading and
flow experienced at the Correctional Center. A single small blower would provide
aeration to :the equalization basin. A single aeration basin designed for a 24-hour
hydraulic detention at the 23,500-gpd flow rate would. be provided, for carbonaceous
BOD removal and nitrification. Aeration equipment would include two 5-hp blowers
in conjunction with diffuser drop leg assemblies. Discharge from the aeration basin
would be directed to a single 3,917-gallon dual hopper bottom gravity clarifier.
Sludge return would be controlled by airlift pumps. Sludge digestion would consist
of an aerobic digester, similar to that at the existing plant.
Following clarification, the effluent would be sent to a prefabricated tertiary filtration
system. The system would include a- splitter box followed by two rapid sand filters,
each having a surface area of 8.68 ft2. The sand filters would ensure that the
proposed plant would consistently meet a final BOD concentration of 5.0 mg/I or
less.
For disinfection, a UV system is recommend. The use of UV systems is.becoming a
-' more attractive alternative in lieu of chlorine disinfection due to strict residual
chlorine effluent limits. In addition, a stand-by dechlorination system (e.g.
dechlorination tablets) is recommended to avoid a high residual chlorine
concentration in the effluent, as result of excessive .use of bleach products at the
prison.
There are two major categories of UV disinfection: low pressure and medium
pressure mercury lamp systems. Low pressure lamp systems are favored over
medium pressure lamps in wastewater applications for, several reasons. The major
reason is thatmedium pressure lamps consume more power than lower pressure
lamp systems, resulting in higher operational costs.: The second reason is that the
increase in power intensity decreases the service life of the lamps. For these
reasons, a low intensity, low pressure system will be installed.
The proposed treatment plant staff would include one full-time operator. Major
responsibilities would entail sampling to show compliance with the permit, equipment
- 2-2

maintenance and daily operations for ensuring the plant operates in a manner that
meets.the treatment objectives.
Listed in Tables 2-2, 2-3 and 2-4 are the estimated capital and operating costs along
with the net present worth analysis, for the proposed Iredell Correctional Center
WWTP. With regards to the operating costs, it was assumed that operating the
aeration equipment would constitute the majority of the costs and that the sludge
disposal costs would be insignificant based on the limited amount of solids
generated.

UPGRADE EXISTING DISINFECTION SYSTEM
Another alternative is to further investigate the structural integrity of the existing
package plant and estimate the plant's remaining service life. In the event the
xi tingaplant could _.remain_in_ operation _for 5P-ypg _ r_ri5aff7it may be a feasible
option to continue to operate the existing treatment plant and upgrade the necessary
unit processes for complying with the revised permit.
As previously mentioned, the existing equipment (as opposed to the tankage) is in
satisfactory condition and there is sufficient capacity to comply with the new permit
with the exception of the residual chlorine limit. Dechlorination would be required to
achieve the effluent chlorine limit. Another option would be to install an ultraviolet
(UV) disinfection system. We recommend an UV system since it is straightforward
in operation and eliminates the handling and storage costs associated with
chemicals. However, a stand-by dechlorination system (e.g. dechl`or�inatio;ntable#sl)
is recommended to avoid a high residual chlorine concentration in the effluent, as
result of excessive use of bleach products at the prison.

The net present worth analysis assumes that the existing treatment facility could
remain in service approximately ten more years. Following that ten-year period, a
new package treatment plant would be constructed similar to the plant described
under the Surface Water Discharge alternative. The new package plant would have
a service life of 20 years. For the purpose of this analysis, it is assumed that the
salvage value of the new packageplant following a ten-year period would be
approximately 50% of the initial investment. The costs associated with the new
package plant were only evaluated for the first ten years, thereby allowing all
alternatives analyzed in this report to be compared over a 20-year period.

CONNECTION TO A PUBLICLY OWNED TREATMENT WORKS (POTW)
This option entails routing the raw wastewater from the Iredell Correctional Center to
the City of Statesville, which is the closest city with a POTW. With this alternative, a
pump station would be installed in lieu of the existing treatment plant. The raw
wastewater would be pumped to a manhole that is part of the collection system
serviced by the City of Statesville's Fourth Creek wastewater treatment plant
(WWTP).
Prior to considering this alternative, approval must be obtained by the public works
director and city council of Statesville. A preliminary indication of acceptance from
the Director of Water and Wastewater Treatment, Joe Hudson, was obtained on
December 9, 1998, by telephone.' However, acceptance by Wayne Lambert, Public
Works Director, and the approval by the City Council of Statesville are required prior
to accepting . additional flow. Furthermore, assessments of Fourth Creek's
wastewater treatment capacity to accommodate additional flow needs to be verified.
Currently, the Fourth Creek WWTP is a six million -gallon per day (MGD) activated
sludge process with tertiary treatment. However, the facility is only permitted for 4.0
MGD.
r- According to the Public Works Department for the City of Statesville, the nearest
manhole where a connection could be made is approximately 2.5 miles from the
Correctional Center. The manhole is located near the intersection of Jane Sower
Road and US Highway 21 and is part of the collection system served by the Fourth
Creek WWTP. Approximately 13,200 lineal feet (LF) of 4-inch diameter force main
in conjunction with 400 LF of 16-inch diameter bore under Interstate 77 is required to
connect Iredell Correctional Center to the City of Statesville's collection system. See
2-5

Figure 2-2 for the proposed piping layout and relationship to the prison. The lift
station for pumping the raw sewage from the Correctional Center would consist of
two 30 horsepower non -clog centrifugal pumps. Each pump would be rated for 80
gallons per minute (gpm). The pumps would be alternated to ensure even wear and
are expected to operate 4.9 hours per day.
Major costs associated with this alternative include the power consumption of the
pumps and the monthly sewer rate that the city would impose on the Correctional
Facility. Based on the current sewer rate for customers outside the city limits, the
Correctional Facility would pay $18.25 for the first 2,250 gallons and $7.925 per
1,000 gallons per month thereafter.
Listed in Table. 2-8 is estimated capital cost associated with the lift station for
pumping the raw sewage from the Iredell Correctional Center to Statesville's
collection system.

CONNECTION TO A PRIVATELY OWNED TREATMENT WORKS
Another alternative is to route the discharge from the Correctional Facility to a
nearby privately owned treatment plant. The closest package plant is located
approximately 1.5 miles away from the prison on the Statesville Auto Auction
property. The existing package plant at the Auto Auction was originally rated for
50,000 gpd, but due to the flows experienced at the plant it was modified and is now
currently permitted for only 12,000 gpd. Discussions with the manager of Auto.
Auction indicate that there is a possibility of a cooperative agreement between
Statesville Auto Auction and the Correctional Center.
In order for this to be a viable option, the current wastewater plant at the Auto
Auction property would need to be modified and the permit renewed to
accommodate the additional flow. Furthermore, a lift station would need to be
installed similar to that required for connecting to Statesville's WWTP. Other issues
_. that would need to be addressed are contractual agreements between both parties,
as well as negotiating fees for modifying the existing treatment plant. Due to the
vagaries of the economy, we do not recommend this alternative because of the
potential risk associated with the Auto Auction going out -of business.
LAND BASED DISPOSAL
Land based disposal methods that were explored consisted drip irrigation, mound
systems and spray irrigation systems. According to the Soil Survey of Iredell
County, North Carolina, Soil Conservation Service, June, 1964 the predominate soil
types for the area in question include the Wehadkee, Chewacla, Warne, Roanoke,
Lloyds and Wickhams. The first four soil types listed above are prominent in the low
lying wetland area south of the plant. They have low permeability characteristics,
thereby restricting their use in an application that results in prolonged irrigation.
These. soil types (Wehadkee, Chewacla, Warne and Roanoke) predominate in the
low lying wetland area south of the plant. Therefore, the land that was
predominately made-up of these soil types was eliminated and not considered for
land disposal methods. This resulted in approximately 20 acres of land that could be
used for treatment.
2-8

To determine the true permeability characteristics and infiltration limitations of a
given soil type, extensive, fieldwork and sampling is recommended. Due to time
limitations, research was conducted utilizing Iredell's Soil Survey report in
_ conjunction with the EPA Process Design Manual for Land Treatment of Municipal
Wastewater to determine an appropriate rate given the nature of the soil type.
Based on a permeability rate of 2.6 centimeters per week (cm/wk) in conjunction
with an average daily flow 23,500 gpd (89 m3/day), the following equation is applied
to determine the land requirements:
Required Land, acres =(Q)(365)(100)(2.471)/(Lw)(10,000)
Average daily flowrate, Q - 89 m3/day
Hydraulic loading rate, Lw - 2.6 cm/wk
Time period for applying wastewater, T - 35 weeks/year
Conversion Factor from hectares to acres - 2.471
Based on the calculation, approximately 9.0 acres are required to provide adequate
treatment at the design flow rate of 23,500 gpd. According to the Guide for the
Evaluation of Wastewater Disposal Alternatives, a 100% redundancy should be
incorporated into the design. This results in a required land area of 18 acres.
Furthermore, additional land is required for providing buffer zones, preliminary
treatment and access roads. It is recommended that an additional 20% of the 18-
acre land requirement be allocated for these purposes, thereby requiring 22 acres.
Due to insufficient buffer area, nearby dorms and residences and the potential health
- risks associated with the spray of aerosols from the treatment system. Also, this
option does not provide flexibility for expansion in the event the prison expanded.
We therefore do not recommend further pursuing this option due to potential health
risks and lack of flexibility.
WASTEWATER REUSE
North Carolina's rules "For Use of Reclaimed Water" (15A NCAC 2H.0219(k))
require tertiary treatment, buffer restrictions, and adequate storage to contain any
effluent not conforming to themandated treatment levels. The proposed package
treatment plant discussed in this report will produce an effluent suitable for reuse
applications. However, the water could only be used for non -potable applications.
The correctional facilities demand for non -potable water is limited to the point that
this is not a viable option. Furthermore, there is potential liability. associated with
utilizing the reuse water at the Correctional Facility. For example, use of the non -
potable water for applications requiring potable water.
Further research was conducted to determine if a nearby source requiring non -
potable water was available, such as a ,golf course. The closest source was the Fox
Den Country Club, which was more than five miles from the prison. The associated
costs for this option resulted in this alternative being cost prohibitive.
2-9

SECTION 3
SUMMARY OF RECOMMENDATIONS
Based on our review of potential alternatives for the Iredell Correctional Center,
three alternatives were deemed viable; as summarized in Table 3-1. The first two
alternatives entailed either constructing -a new package plant adjacent to the existing
plant or upgrading the current disinfection system. The third option is to construct a
lift station to transport the raw wastewater to the . City of Statesville's collection
system, whereby the wastewater could be treated by the Fourth Creek wastewater
treatment plant.

'Does not include costs for repairing the existing tankage and annual maintenance costs for the existing equipment.
Based upon our review of the three potential alternatives, we recommend .that the
Department of Correction conduct a more thorough evaluation of the tank corrosion,
and repair it as necessary. At the same time, it should allocate funding for
upgrading the disinfection system from chlorine to UV. Standby chemical
' dechlorination equipment should be considered, if there is a concern that chlorine
bleach cleaning products could pass through the treatment process.
Once the future of the Correctional Center becomes clearer, the Department of
Correction should plan for replacement of the existing plant as it is approaching the
end of its design life.
This approach should result in continued compliance with current and anticipated
discharge requirements in a cost-effective, fiscally prudent manner.

HYDRO -AEROBICS, INC.
WASTEWATER TREATMENT INDUSTRY
. Hydro -Aerobics is nowtaking a vital role.in the wastewater
treatment industry. Today this industry is being recognized as
crucial to our world if we are to maintain our present way of life
and improve the environment in which we live. To answer this
need, Hydro -Aerobics, backed byyears of experience of its cor-
porate personnel, have developed a highly efficient wastewater
treatment system that will produce the quality of effluent our
environment requires. We call. it the "HYDRO -AEROBICS"
System.
HOW THEY ARE USED
The Hydro -Aerobics System is a unique intermediate size
biological wastewater treatment system. The Hydro -Aerobics
facility is designed and engineered specifically for those small
- complexes of people who are temporarily or permanently
residing outsidethe reach of municipal waste disposal systems.
Typical applications are for:
• Suburban Subdivisions • Recreational Facilities
• Mobile Home Parks • Highway Rest Stations
• Housing Developments • Power Stations
• Resort Areas • Apartment Complexes
• Motels • Industrial Facilities
OUTSTANDING FEATURES
- Hydro -Aerobics Systems are compact and self-contained.
They can be installed both below or above grade with a minimum
of installation expense. The facilities are portable and reusable.
Since they are relatively small in size and odor -free, they canoe
installed at almost any location, and landscaped to match the
surrounding area. Several otherfeatures ofthe Hydro -Aerobics
Systems are:
• High Degree of Treatment (85-90%xBOD5 Removal)
• Low Maintenance Cost
• Ease of Installation
FACTS ABOUT THE PROCESS
The Hydro -Aerobics System is a type of biological treatment
for domestic waste using the extended -aeration modification of
the activated sludge process. The extended aeration process
was discovered many years ago by wastewater treatment plant
operators trying to operate a conventional municipal activated
sludge type system under low flow and high BODs loadings.
They found under these conditions a high quality effluent could
be achieved. The basic design was an extended aeration period
(approx. 24 hours) coupled with a defined settling period (approx.
4 hours). One of the innovators stated it simply: "We are using
Mother Nature's way of treating the -wastewater by condensing a
very long babbling brook into one compact aeration zone."
Theoretically, the extended aeration process purifies the
sewage by the destruction of the organic compounds using air to
mix and oxidize the volatile material (both solid and liquid) into
gas, water and sludge. By continued aeration of these
concentrated solids biological organisms are produced and grow
in colonies. The colonies will attach themselves to the volatile
materials breaking it down into water, carbon dioxide and ash.
The result being a clear and odor -free effluent.

E. Zero Flow Condition
The facility discharges into a stream with 7Q10/30Q2=0 cfs. Removal of discharge is
recommended if a more environmentally sound alternative is available at an economically
reasonable cost. An engineering report evaluating alternatives to discharge is due 180 days prior to
expiration along with the renewal application. As part of the report, the cost of constructing a
treatment plant that will meet limits of 5 mg/l BOD, 2 mg/l NH3, 6 mg/l (min.) DO, and 17 µg/1
chlorine should be included, if there are no feasible alternatives to surface discharge. Upon review
of the engineering report, the Division retains the right to reopen and modify this NPDES permit to
require removal of the discharge or to revise the permit limitations within a specified time schedule.

Subject: NPDES Permit No. NCO029742
Iredell Correction Center
Iredell.County, NC
Dear Mr. Stovall:
Our records indicate that NPDES Permit No. NCO029742 was
issued on September 26,-_ 1994 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 Permitand
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 (s). Your discharge(s) 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 the
reporting forms.furnished to you 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.
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.

SECTION E. DEFINITION
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Natural
Resources and Community Development.

Part II

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 sample and measured, divided by the number
of daily discharges samples 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 .lied -Cation is
identified as "Daily Average" or "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 samples 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
1J.mJ.tat_i.on is identified as "Weekly Average" in Part T of the permit.
C. The "mexi.mum daily discharge" is the, total mass (weight:) of a
pollutant discharged during a calendar clay. If on.1y oi.e 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 ti).e. total mass of all
daily discharges sample 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 .limitatJon is defined as
"Annual Average" in. Part I of the permit.

Part II
Page 12 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
samples 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" or
"Daily 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 measu.0 ed 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" cinder "Other
Limits" in Part I of the permit.
C. The "maximum daily concentration" is the concentration of a pollutant
discharge during a calendar day. It is identified as "Daily Maximum"
under "Other Limits" .n Part T of the. permit.
d. The "average annual concentration," other then 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.

Part II
Page 13 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.
8. Types of Samples
a. Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composi.te,sampl.e is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
b. Grab Sample: Grab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually.
9. Calculation of Means
a. Arithmetic Mean: The arithmetic mean of any set of values is the summation
of the individual values divided by the number of individual values.
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.
12. Toxic Pollutant
A toxic pollutant is any pollutant .listed as toxic under Section 307(a)(1) of
the Clean Water Act.

Dear Mr. Wilson:
Our records indicate that NPDES Permit No. NC 002974.2 was .
issued on October 17, 1988 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 M3.
Page M3 sets forth the effluent limitations and monitoring
requirements for your discharge(s). Your discharge(s) 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 the DMR
forms furnished to you by this Agency.. If'you have not received
these forms, they should be arriving shortly. If you fail to
receive the form, 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,
otherwise the forms may be returned to you as incomplete.
Failure to properly complete the forms may also result in an
automatic $300.00 fine.

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 day per violation plus
criminal penalties may be assessed for such violations.
As a final note, an NPDES Permit is normally issued for a

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 M-1 or I-1.
of the Permit. Also note that NPDES Permits are not
transferable. If you, as the Permittee, cease to need this
Permit, then you should request that the Permit be rescinded.
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

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

Part I
Page of
Permit No. NC
e. Geometric Mean: The geometric mean of any set of values is the
Nth root of the product of the individual values where N is equal
to the number of individual values. The geometric mean is equiva-
lent to the antilog of the arithmetic mean of the logarithms of
the individual values. For purposes of calculating the geometric
mean, values of zero (0) shall be considered to be one (1).
f. Composite Sample: A "composite sample" is any of the following:
(1) Not less than four influent or effluent portions collected
at regular intervals over a period of 24 hours and composited
in proportion to flow.
(2) Not less than four equal volume influent or effluent portions
collected over a period of 24 hours at intervals proportional
to the flow.
(3) An influent or effluent portion collected continuously over
a period of 24 hours at a rate proportional to the flow.
g. Grab Sample: •A "grab sample" is a single influent or effluent
portion which is not a composite sample. The sample(s) shall be
collected at the period(s) most representative of the total discharge.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC
regulations published pursuant to N. C. G. S. 143-215.63 et seq, The
Water and Air Quality Reporting Act, and to regulations published pursuant
to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act,
As Amended, and Regulation 40 CFR 136.
5. Recording Results
For each measurement or sample taken pursuant to the requirements of
this permit, the permittee shall record the following information:
a. The exact place, date, and time of sampling;
b. The dates the analyses were performed; and
c. The person(s) who performed the analyses.
M6

PART I
Page of
Permit No. NC
6. Additional Monitoring by Permittee
If the permittee monitors any pollutant at the location(s) designated
herein more frequently than required by this permit, using approved
analytical methods as specified above, the results of such monitoring
shall be included in the calculation and reporting of the values required
in the Monthly Monitoring Report Form (DEM No. MR 1.0, 1.1, 1.2, and 1.3)
Such increased frequency shall also be indicated. The DEM may require
more frequent monitoring or the monitoring of other pollutants not
required in this permit by written notification.
7. Records Retention
All records and information resulting from the monitoring activities
required by this Permit including all records of analyses performed and
calibration and maintenance of instrumentation and recordings from
continuous monitoring instrumentation shall be retained for a minimum of
three (3) years, or longer if requested by the Division of Environmental
Management or the Regional Administrator of the Environmental Protection
Agency.

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

Part II - DESCRIPTION OF EXISTIING TREATMENT WORKS
The Iredell County Subsidiary of the Department of Corrections is presently
being served by a 16,250'�allon septic tank, followed by a dosing tank,
and dual surface sand filters.
DESCRIPTION OF PROPOSED TREATMENT WORKS
The Department of Corrections proposes to construct extended aeration plant
with disinfection and a cascade for aeration.
Part III - EVALUATION.AND RECOMMENDATIONS
The average population at the Iredell Prison Unit is 130 to 140 inmates.
Using an anticipated flow of 100 gallons/inmate/day it is apparent that

k
Page Two
the proposed 18,000 gpd package plant is of adequate design. The surface
sand filters have a combined area of approximately six thousand square feet
(0.1377 acres). This indicates 116,000 gallons/acre/day which is in the
accepted range of 75,000 to 125,000 gallons/acre/day.
The sand filter was free of grotrth, fairly level, and apparently being
well maintained.
The construction fo disinfection facilities and a cascade for aeration of
the effluent should allow the treatment plant to meet the limits proposed
by Technical Services 4hich are:
BOD, 5-Day, 200C 21 mg/l
NI-13 as N 18 mg/l
TSS 3-� mg/l
Fecal Coliform (Geometric Mean) 1000/100 ml
Dissolved Oxygen (Minimum) 6.0 mg/l
T is recommended a five year I,PDES Permit be issued this facility.

Part II - DESCRIPTION OF EXISTING TREATMENT WORKS
The Iredeli County Subsidiary of the Department of Corrections is. presently
being served by a 16,250 gallon septic tank, followed by a dosing tank,
.and dual surface sand filters. The proposed.wastewater-treatment facility is an extended. aeration type
treatment: plant consisting of a- bar -"screen, comminutor.,- an aerated surge
tank,'dual 40 gpm influent pumps,.aeration basin with diffused air, dual
hopper clarifier, an.aerated sludge- hol-ding :tank_, post -aeration 'and
disinfection. This new treatment facility will also utilize the,existing.
surface sand filters prior to discharge :to the post aeration unit..
Part III - EVALUATION! AND RECOMMENDATIONS-
-Inspection of this facility revealed.that construction of the -proposed
treatment plant had begun. The existing system was in good repair but
was experiencing some operational problems.

< Page Two
Past self -monitoring data shows violations .of the existing NPDES Permit
limitations for BOD5 and TSS. Also, the self -monitoring of the Permit
parameters.is not being conducted in accordance with the Permit.
Operation and Maintenance procedures should be increased and improved
upon completion of construction.
It.is recommended that the NPDES Permit for this facility be renewed.

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.

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
