• � 1
Page Three
The plans and specifications were reviewed and the following
comments are offered:
1 . The plans do not address removal and storage of the clay
liner . It is possible that the liner may have significant
concentrations of Cadmium. The soil should be stored in a
manner to prevent any runoff .
2 . The plans show a possible bypass from the main pumping station
to manhole #SM. The bypass should be plugged .
It is recommended that the plans and specifications be
approved provided the above mentioned concerns are addressed .

The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure -Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 39% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of January, April, July, October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally,DEM Form AT-1 (original)is to be sent to the following address:
Attention:

Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for'
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U. S. Environmental Protection Agency dated December 6, 1983.
If any parts, measurement frequencies or sampling requirements contained in this
modification of the permit are unacceptable to you, you have the right to an adjudicatory hearing
upon written request within thirty (30) days following receipt of this letter. This request
must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer

be final and binding.
Please take notice that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirement to obtain other permits which may be
required by the Division of Environmental Management or permits required by the Division of

Dear Mr. King:
Our records indicate that NPDES Permit No. NC0020591 was
issued on July 25, 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 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 4-11.
Pages 4-11 set 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.
Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment

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

I. Chronic Toxicity Testing Requirement
The effluent discharge shall at no time exhibit chronic toxicity in any two
consecutive toxicity tests, using test procedures outlined in:
1). The North Carolina Ceriodaphnia chronic effluent bioassay procedure
(North Carolina Chronic Bioassay Procedure - Revised *February 1987) or
subsequent version.
The effluent concentration at which there may be no observable inhibition of
reproduction or significant mortality is 39% (defined as treatment two in the
North Carolina procedure document) . The permit holder shall perform quarterly
monitoring using this procedure to establish compliance with the permit
condition. The first test will be performed after thirty days from issuance of
this permit during the months of January, April, July, and October. Effluent
sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be
entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which
it was performed, using the parameter code TGP3B. Additionally, DEM from AT-1
(original) is to be sent to the following address:
Attention: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting
chemical/physical measurements performed in association with the toxicity
tests, as well as all dose/response data. Total residual chlorine of the
effluent toxicity sample must be measured and reported if chlorine is employed
for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified
limits, then monthly monitoring will begin immediately until such time that a
single test is passed. Upon passing, this monthly test requirement will revert
. to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the
North Carolina Division of Environmental Management indicate potential impacts
to the receiving stream, this permit may be reopened and modified to include
alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document,
such as minimum control organism survival and appropriate environmental
controls, shall constitute an invalid test and will require immediate retesting
(within 30 days of initial monitoring event) . Failure to submit suitable test
results will constitute noncompliance with monitoring requirements.

J. The permittee shall conduct a test for priority pollutants annually at the
effluent from the treatment plant. The discharge shall be evaluated as follows:
1) A pollutant analysis of the effluent must be completed annually using
EPA approved methods for the following analytic fractions: (a)
• purgeables (i.e. , volatile organic compounds);:. (b) acid extractables;
(c) base/neutral extractables; (d) organochlorine pesticides and PCB s
(e) herbicides; and (f) metals and other inorganics. The Annual
Pollutant Analysis (APA) Monitoring Requirement Reporting Form A, to
be provided to all discharges affected by this monitoring requirement,
describes the sampling and analysis requirements and lists chemicals
to be included in the pollutant analysis. This monitoring requirement
is to be referred to as the "Annual Pollutant Analysis" (APA) .
2) Other significant levels of synthetic organic chemicals must be
identified and approximately quantified. For the purpose of
implementing this requirement, the largest 10 GC/MS peaks in each
organic chemical analytic fraction (or fewer than 10, if less than 10
unidentified peaks) occur for chemicals other than those specified on
the APA Monitoring Requirement Reporting Form A should be identified
and approximately quantified as stated in the APA Reporting Form A
instructions. This part (item 2) of the APA monitoring requirement is
to be referred to as the "10 significant peaks rule".

Iredell County, NC
Dear Mr. King:
Enclosed please find a copy of a Special Order by Consent
developed in response to a request from the City of Statesville.
Through the Order conditional compliance can be achieved while
the City actively pursues the capability to comply with the final
effluent limitations contained in the NPDES Permit issued to the
City for the operation of its Third Creek wastewater treatment
facility.
Thoughtful consideration was exercised in the development of
the scheduled activities, interim limitations and other terms
included in the Order. Please be aware, however, that any of the
required activities are only suggestive of needed additional
activities and can function only as a basic framework. It is the
responsibility of the City to fully characterize the basic
activities and bring them to fruition.
A major goal in effluent limits development is the
protection of the water quality of the receiving stream. Limits
are based in part on the assimilative ability of the receiving
stream, stream standards specific to all similarly classed
streams, and background concentrations relative to specific
pollutants . Other pollutants may be of concern, but will not be
limited, having instead monitoring only requirements . While a
special order may provide for conditional compliance, it may, for

Permit limit for Cadmium, the enclosed Order includes stipulated
penalties for any failures to comply with the terms and
conditions of the Order.
Thoroughly review the Order. As the document title
suggests, it will be entered into only after the City' s consent.
If the City is satisfied with the content of the Order, please

NC0020591 for operation of an existing wastewater
treatment works and for making an outlet therefrom for
treated wastewater to Third Creek, Class C waters of this
State in the Yadkin-Pee Dee River Basin, but is unable to
comply with the final effluent limitations for Cadmium
set forth in the Permit. Compliance will require the
removal of accumulated old sludge from the system, and
the renovation of existing facilities. Compliance will
also require the continued control of industrial
discharges to the treatment works through the City's
approved and implemented industrial pretreatment program
and through the local sewer use ordinance.
(b) That noncompliance with final effluent limitations
constitutes causing and contributing to pollution of the
waters of this State named above, and the City is within
the jurisdiction of the Commission as set forth in G.S.
Chapter 143, Article 21.
(c) That the City desires to cause or allow the discharge of
190,000 gpd of additional wastewater to the treatment
works, and that the discharge of such additional
wastewater will not result in any significant degradation
of the quality of any waters .
(d) That the City has secured financing for planned
renovation and construction activities which, when
completed and placed into operation, will be sufficient
to adequately treat the wastewater presently being
discharged and the additional wastewater desired to be
discharged, to the extent that the City will be able to
comply with final permit effluent limitations .

(e) Since this Special Order is by Consent, neither party
will file a petition for a contested case or for judicial
review concerning its terms.

3. The City agrees that unless excused under paragraph 4, the
City will pay the Director of DEM, by check payable to the
North Carolina Department of Environment, Health and Natural
Resources, stipulated penalties according to the following
schedule for failure to meet the deadlines set out in
paragraphs 2 (b) and 2(e) , or failure to attain compliance with
the effluent limitations/monitoring requirements contained in
Attachment A, except as provided for in paragraph 2(c) above.
Failure to meet a schedule date $100/day for the first
7 days; $500/day
thereafter
Failure to maintain compliance with $1000/violation
any modified limit contained in the
SOC.
Failure to achieve compliance with Single monetary
final effluent limits by December 31, penalty of $5,000
1995.

V Monitoring frequency violations $100 per omitted value
per parameter
Failure to submit progress reports $50/day for the first
7 days; $250/day
thereafter
4 . The City and the Commission agree that the stipulated
penalties are not due if the City satisfies the DEM that
noncompliance was caused solely by:
a. An act of God;
b. An act of war;
c. An intentional act or omission of a third party; but this
defense shall not be available if the act or omission is
that of an employee or agent of the defendant or if the
act or omission occurs in connection with a contractual
relationship with the permittee;
d. An extraordinary event beyond the permittee's control.
Contractor delays or failure to obtain funding will not
be considered as events beyond the permittee's control;
or
e. Any combination of the above causes .
Failure within 30 days of receipt of written demand to pay the
penalties, or challenge them by a contested case petition
pursuant to G.S. 150B-23, will be grounds for a collection
action, which the Attorney General is hereby authorized to
initiate. The only issue in such an action will be whether
the 30 days have elapsed.
5. In accordance with the provisions of G.S. 143-215 .67 (b) the
Commission allows the City to accept the additional waste
specified below to its waste disposal system:
190,000 gpd of additional wastewater. The nature of the
additional flows is such that the waste characteristics do not
exceed those generally associated with domestic waste or are
pretreated to domestic strengths . Waste of greater than
normal domestic strength may be accepted if the parameter(s)
that exceed normal domestic strength wastewater are not those
for which interim limitations have been developed, and it can
be demonstrated to the satisfaction of the Director that the
additional waste will not adversely affect the treatment
efficiency of the treatment system for any modified parameter
or result in the violation of any other permit limitation.
All new and proposed industrial waste tributary to the system
must be controlled using all needed mechanisms including, but
not limited to, adoption and implementation of industrial
waste control and pretreatment ordinances. No wastewater can

be accepted which will add toxic pollutants in quantities not
generally associated with domestic wastewater characteristics,
unless the acceptance of the additional wastewater can be
supported through appropriate analyses acceptable to the
Director.
6 . This Special Order by Consent and any terms, conditions and
interim effluent limitations contained herein, hereby
- supersede any and all previous Special Orders and Enforcement
Compliance Schedule Letters, and terms, conditions, and
limitations contained therein issued in connection with NPDES
Permit No. NC0020591 . In the event of an NPDES Permit
modification or renewal, any effluent limitations or
monitoring requirements contained therein shall supersede
those contained in Attachment A of this Special Order by
Consent, except as modified and contained in paragraph 2 (d)
above.
7 . Any Violation of terms of this Special Order by Consent,
including paragraphs 2 (b) and 2(e) above and Attachment AL
except as provided for in paragraph 2 (c) above, shall
terminate paragraph 5 of this Order and any authorized
additional waste not previously connected to the system shall
not thereafter be connected until the necessary sewerage
system improvements have been completed and placed in
operation.
8. Noncompliance with the terms of this Special Order by Consent
is subject to enforcement action in addition to the above
stipulated penalties, including injunctive relief pursuant to
G.S. 143-215.6C.
9 . The permittee, upon signature of the Special Order by Consent,
will be expected to comply with all schedule dates, terms, and
conditions of this document.
10. This Special Order by Consent shall expire March 31, 1996 .

NPDES Permit No. NC0020591
Third Creek WWTP
Iredell County
Dear Mr. Hudson:
In response to the Petition for a Contested Case Hearing, 94 EHR 0953, filed on September 2,
1994, the following outlines the basis of the permitting decisions and the modifications the Division is
willing to make to the NPDES permit No. NC0020591 for the Statesville Third Creek wastewater
treatment plant. Attached is a copy of the permit incorporating the modifications. This letter will also
serve as confirmation for the meeting scheduled on October 26, 1994 to discuss the issues below.
As you may be aware, the development of permit limits for toxic substances is based on a
determination of whether reasonable potential exists that the pollutant of concern may be discharged in
quantities which would result in a violation of the water quality standard in the receiving water.
Therefore, two computations are used to make this determination. First, the allowable pollutant
concentration which will protect the water quality standard is calculated(i.e.,permit limit) and second,
the potential for exceedances of the allowable concentration is determined.
The allowable concentration is calculated using a mass balance equation which takes into
consideration the wastewater treatment plant discharge volume,the instream flow, the upstream ambient
concentration of the pollutant, and the water quality standard. The upstream concentration is assumed
to be zero unless stream data indicate otherwise.
The determination of reasonable potential is based on a statistical evaluation of the data available
for each pollutant of concern. Using existing effluent data, the variability of the data is calculated and
the maximum expected concentration is determined. Any evaluation which results in a predicted
concentration greater than the allowable concentration results in a permit limit. In the case of Third
Creek WWTP,existing Long-term Monitoring Plan (LTMP) data were used in the calculations. In each
case that a limit was implemented, the determination was conclusive that reasonable potential existed for
the allowable concentration to be exceeded. The reasonable potential methodology for determining
whether a toxic parameter should be limited in a permit is based upon the U.S. Environmental
Protection Agency Technical Support Document.
The development of the water quality standards for metals in North Carolina was on the basis of
protection from chronic effects. Therefore, in cases where a facility requests that the permit limit for
toxicants be expressed as a weekly average, the Division will modify the permit to incorporate a daily
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]
An Equal Opportunity Affirmative Action Employer 50% recycled/ 10%post-consumer paper

maximum and weekly average limit. The weekly average is calculated as stated above, and the daily
•
maximum is calculated based on the 1/2 Final Acute Value(or Criteria Maximum Concentration). For
purposes of compliance, samples are required to be collected and analyzed on a weekly basis. If the
initial sample analyzed complies with the weekly average limit, no additional analysis of samples is
required. If the analysis documents concentrations above the weekly average limit, the additional
samples collected that week may be analyzed and the results of the multiple samples averaged to
determine compliance. For purposes of compliance, any analysis result reported as less than the
detection level is considered to be zero.
Weekly average and daily maximum values were placed in the Statesville Third Creek permit.
However, the daily maximum values for cadmium, and cyanide were miscalculated. The original
permitted values and the corrected values are listed below.
Parameter Daily Maximum Daily Maximum Weekly Average
WO/ (ug/1) iaa
CORRECTED
Cadmium 8.0 12.8 5.2
Cyanide 35 51.6 12.9
The Division also corrected the daily maximum/weekly average value for lead. The corrected
daily maximum was calculated as 86.7 µg/1 and the weekly average as 64.5141.
The existing North Carolina standards for cadmium and cyanide were developed and are
expressed as total recoverable. To use different criteria for developing permit limits, as suggested in the
Petition, would necessitate approval by the Environmental Management Commission (EMC) and by
EPA, as this would be considered a variance of the existing regulations via the development of a site-
specific standard.
The Code of Federal Regulations (CFR)governing metals limits in NPDES permits allows three
exceptions from metals limits being expressed as total recoverable. The pertinent exception in this case
allows a dissolved fraction limit when required to carry out the provisions of the Clean Water Act.
While this is a broad statement, EPA Interim Guidance released in October 1993 specifically
recommends that no translation between total and dissolved be used by states with standards expressed
as total recoverable until the state standards are changed to the dissolved form. The guidance further
states that implementation of this exception should occur only in "highly unusual circumstances".
The North Carolina General Statutes, §143-214.3, allow any person to petition the EMC for a
hearing to revise the water quality standards. The procedure requires the EMC to find that the
application of effluent limits more restrictive than those promulgated by EPA would result in adverse
social and economic impact, disproportionate to the benefits to public health, safety or welfare as a
result of maintaining the existing standard and that there exists no reasonable relationship between cost
of achieving the limits, including incremental benefits to the receiving waters,to be obtained from the
application of the effluent limits. The documentation to demonstrate that the above requirements are met
will include an evaluation of sources and a source reduction plan, an audit to assure proper function and
management of the facility, pollution prevention planning, cost analysis of all available treatments
(including source reduction), etc. If the EMC determines that the conditions of §143-214.3 are
satisfactorily met,then a study plan will have to be developed demonstrating how sufficient data will be
collected to develop a site-specific criterion. This criterion will eventually have to be promulgated as an
amendment to the existing water quality standards regulations.
Development of a site-specific standard requires chemical analyses of the receiving water and
the effluent and a biological assessment of the surface waters. The EPA guidance requires that the
development of a site-specific standard includes an assessment of the genus and species which "occur at
the site". The phrase "occur at the site" has been defined to include species that are usually present,are
present seasonally,are present intermittently, were at the site in the past and could return with improved
conditions, and are present in nearby bodies of water and could return with improved conditions.
Upon completion of the study and approval by the EMC,the site-specific standard is then submitted to

the EPA for review and approval in accordance with the program delegation and Chapter 40 CFR Part
131.5. Attached for your information is an outline of the eligibility requirements and study plan
requirements for the development of site-specific criteria. Statesville should be aware that the site-
specific criterion will be used for calculating the cadmium and cyanide limits, even if the criterion is
found to be lower than the existing water quality standards. If the City chooses to pursue the option of
a site-specific standard, a study plan will have to be developed in accordance with the attached draft
guidance,reviewed and approved prior to initiation.
In regard to the specific issue raised on the cyanide limit, until an EPA approved method for
analyzing free cyanide becomes available,EPA recommends applying the criteria using the total cyanide
method [as stated in Ambient Water Quality Criteria for Cyanide - 1984 (USEPA 1985)]. The City
should review its current method for the analysis of cyanide. Nitrates have been found to interfere with
cyanide analysis resulting in potentially falsely elevated cyanide concentrations being documented. The
sixteenth and subsequent editions of Standard Methods have included sulfamic acid pretreatment as part
of the procedure for performing cyanide analysis to reduce this interference.
There are several items that Statesville should take into consideration while reviewing the City's
options. First, even if the showings required by the North Carolina General Statutes and the Code of
Federal Regulations can be made, there is no guarantee that the EMC will approve such a petition.
There is also no guarantee that EPA will accept site-specific metals criteria using the dissolved form
from North Carolina, given that the Water Quality Section's existing standards are expressed as total
recoverable. Additionally,the City should be made aware that the current North Carolina surface water
quality standard for cadmium (2 µg/1) is higher than the EPA water quality criteria(0.66 µg/1). North
Carolina recalculated the EPA standard after deleting salmon and trout genus mean acute values. Since
that time, EPA has published new guidance which includes additional information from more recent
studies on cadmium that may result in a more stringent standard.
As stated earlier, a meeting has been scheduled for October 26, 1994, at 1:00 pm in the 11th
Floor Conference Room of the Archdale Building to discuss the above issues. If you have any
questions concerning this permit,please contact Susan Wilson at telephone number 919/733-5083.

Site-Specific Criteria Guidance Outline
* No guarantee that EPA will accept site-specific metals criteria using dissolved from
North Carolina. Prothro memo October 1, 1993: "In those States where the standards are.
in the total recoverable or acid soluble form,EPA recommends that no translation be
used until the time that the State changes the standards to the dissolved form."
Determining Eligibility for Site-Specific Criteria
One of the following requirements must be fully documented per G.S. 143-214.3(b):
• Natural background conditions in the stream segment preclude the attainment of
the applicable water quality standards; or
• Irretrievable and uncontrollable man-induced conditions preclude the attainment
of the applicable water quality standards; or
• Application of effluent limitations for existing sources established or proposed
pursuant to G.S. 143-215.11 more restrictive than those effluent standards and
limitations determined or promulgated by the United States Environmental
Protection Agency pursuant to section 3012 of the Federal Water Pollution
Control Act(CWA)in order to achieve and maintain applicable water quality
standards would result in adverse social and economic impact, disproportionate to
the benefits to the public health, safety or welfare as a result of maintaining the
standards; and
• There exists no reasonable relationship between the cost to the petitioner of
achieving the effluent limitations necessary to comply with applicable water
quality standards to the benefits, including the incremental benefits to the
receiving waters, to be obtained from the application of the said effluent
limitations.
Documentation to demonstrate any of the above requirements is met will include:
• Evaluation of sources &source reduction plan
• Audit to assure proper function and management of facility
• For metals, documentation and demonstration of clean techniques for sampling
and analyses (duplicate sampling with a lab that can do clean techniques)
• Pollution prevention plan
• Cost analysis of all available treatments, including source reduction
If one of the above requirements is judged by the EMC to be satisfactorily met, then
facility will provide Water Quality staff with a study plan demonstrating how sufficient
data will be collected to develop a site-specific criterion. The discharger should be aware
that the site-specific criterion will be used for calculating their effluent limit, even if the
site-specific criterion is lower than the applicable water quality standard.
1 G.S. 143-215.1 -Control of sources of water pollution;permits required. Outlines what activities will
require a permit and describes Commission's powers regarding permits.
2 Section 301 of the Federal Water Pollution Control Act-Effluent Limitations. Outlines minimum
requirements for effluent limitations and requirements for granting modifications. Requires that
modification represent maximum use of technology within economic capability of the owner/operator and
will result in reasonable further progress toward elimination of the discharge of pollutants.

For metals the following steps must be included in any study plan for site-specific
criteria development.
• Clean techniques for sampling and analyses with appropriate QA/QC per latest EPA
guidance3
• Determine site-specific partitioning coefficient for each metal using latest EPA
guidance.4 Assumptions and calculations will be clearly presented to aid in review.
• Sampling will include 20 pairs of dissolved and total recoverable metals samples and
20 total suspended solids samples over all flow regimes from upstream, downstream
and the effluent. The 95th percentile of highest dissolved concentration will be used
for calculation of the partitioning coefficient. This value is a critical condition
analogous to that used for identification of low flows and other critical environmental
conditions.5 Sampling will also include hardness, alkalinity and pH.
• Sampling to determine what portion of the effluent metals becomes bioavailable will
also be conducted. This sampling will require dilution of effluent by receiving stream
waters to critical low flow (7Q10)instream waste concentration and analysis of
dissolved and total recoverable metal concentrations. Dilution water should have total
suspended solids concentrations similar to documented TSS concentrations during
7Q10 flows.
Steps for approval of site-specific standards
• Approval of final site-specific study results by DEM Water Quality staff.
• Compliance with G.S. 143.214.3 and section 301 of the CWA. These regulations state
that the new effluent limit may not endanger human health and may not be less than
either the current effluent guidelines for the discharger or the highest level of treatment
which can reasonably be attained without economic hardship.
• Compliance with state antidegradation policy (15A NCAC 2B .0201) must also be
determined prior to issuing any site-specific effluent limits. Existing uses must be
protected by the site-specific water quality standard.
• Site-specific standards are subject to the procedures for assignment of water quality
standards per 15A NCAC 2B .01016 . Requires public hearings and review by EPA.
• Site-specific standards must be reviewed as part of the Triennial Review of Water
Quality Standards per 15A NCAC 2B .02187. Requires public hearings and review by
EPA.
The final permit would also be noticed per 15A NCAC 2H .01098 and would include
monitoring requirements to demonstrate compliance with sections 305(b) and 303(d) of
the CWA. These sections require states to identify waters not meeting designated uses
and/or waters for which site-specific standards have been developed and to develop total
maximum daily loads or other waste load allocations for section 304(a)(2)pollutants.
Monitoring would include sampling to determine that dissolved site-specific standard not
exceeded.

• Part III Permit No. NC0020591
G. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989)or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 39% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of January, April, July, October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form(MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally,DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Subject: NPDES/Statesville
NPDES Permit No. NC0020591
Third Creek WWTP
Iredell County
Dear Mr. King:
In accordance with your application for a renewal of discharge permit received on December 9,
1993,we are forwarding herewith the subject State- NPDES permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the US Environmental Protection Agency dated December 6, 1983.
In response to the letter submitted June 15, 1994 by Joe Hudson regarding the City's draft
permit, the following comments are offered for your information:
• North Carolina's current procedure for protecting an instream criteria involves an analysis
considering the standard and dilution at the point of discharge. Based on this analysis, a daily
maximum concentration is given in the permit. Although the water effects ratio is being studied,
the Division has not yet accepted this procedure. However, due to the fact that the City has the
ability to perform daily metals monitoring the Division will offer the City daily maximum and
weekly average limits (in lieu of only daily maximum values).
• The potential exists for the facility to exceed the instream criteria for chromium and nickel, which is
the reason a limit was given in the draft permit. The Division will agree to let the City monitor
chromium and nickel for approximately one year before the permit limits are implemented.
• The recommended monitoring frequencies for copper, silver, and zinc of 2/month are based on the
classification of the facility (Class IV) and are standard requirements for all Class IV facilities. The
monitoring frequency of 2/month shall remain for copper and zinc due to its presence i.i the
wastestream and due to the fact that the action levels for these parameters are under review. The
Division will agree to decrease the monitoring frequency for silver from 2/month to monthly. After
one year worth of data has been collected, the City may request a review of the silver monitoring
requirement.
• Mercury monitoring is being dropped from the permit since this parameter is monitored under the
City's Long Term Monitoring Plan. Based on regional office comments and the potential presence
in the wastestream, quarterly monitoring of MBAS, selenium, and chlorides is recommended. The
Division does not believe that quarterly monitoring of these parameters is cost prohibitive for
Statesville. Conductivity monitoring is required for water quality limited facilities [ref. 15A NCAC
2B .0508].

If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicative hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611 -7447. Unless
such demand is made,this decision shall be final and binding.
Please take notice this permit is not transferable. Part II,E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the
legal requirements to obtain other permits which may be required by the Division of Environmental
Management or permits required by the Division of Land Resources, Coastal Area Management Act or
any other Federal or Local governmental permit that may be required.

S. :\1a,;'Dav 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
v.eights 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.

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

7. Qter Mea<urements ..
a. Flow. (MOD): 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 Saes
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
beta een 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. Fat purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

•
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10.ralenda_-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.}lazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12.Tonic Pollutant

G. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure -Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 39% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of January, April, July, October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally,DEM Form AT-1 (original)is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

PART IV
ANNUAL ADM NISTEPJNG AND COMPLIANCE MONTPORING FEE REQUIREMENTS
A. The permittee must pay the annual administering and compliance monitoring fee within 30
(thirty) days after being billed by the Division. Failure to pay the fee in a timely manner in
accordance with 15A NCAC 2H .0105(b)(4) may cause this Division to initiate action to
revoke the permit.

Wasteload Allocation Summary
(approach taken,correspondence with region, EPA,etc.)
Checked A to C book to see if facility was operating within its flow design capacity . I used flow
information from old WLA. Met with Joe Pearce to discuss the Long Term Pretreatment Data. .
Most recent APAM has detection concentrations for Tri- and Di- chlorobenzenes. Request limits
for Chromium and Nickel be set and monitoring for Silver and Selenium based on toxicants
analysis. Staff report requested monitoring for Chlorides, MBAS, and Silver. Requested
quarterly monitoring for Mercury b/c it will not be included in the LIMP, the types of industries,
and there is no data available.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirty days from the effective date of this permit during the months of
Apr, cl 1 ,e)c.4- . Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally,DEM Form AT-1 (original)is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re-opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.
