Lee S. Dukes Water Treatment Plant - NPDES Permit # NCO084387
Mr. Corporon,
Charlotte Water would like to request renewal of NPDES permit NCO084387 at the Lee S. Dukes
Water Treatment Plant. The current permit is set to expire February 28, 2025. Lee S. Duke
Water Treatment Plant is categorized as a conventional technology water treatment plant
[utilizing coagulation, flocculation, sedimentation, and filtration] with discharge of wastewaters
from media filter backwash and sedimentation basins. For your review, and in lieu of the Short
Form 2C we have provided in the past for permit renewals, I am providing the full EPA Form 2 C.
Please find attached to Form C the following:
• Appendix A: Outfall Location Map
• Appendix B: Line Drawing / Treatment Process Synopsis
• Appendix C: Waiver Request
• Appendix D: Biological Toxicity Test
• Appendix E : Additional Information
There are a couple of elements that I want to bring to your awareness and/or consideration:
• Relative to Section 6 -improvements of the permit application, no construction or
improvements have been made to the wastewater treatment process at Dukes since the
last permit was implemented.
• As a point of reference, all water quality results from the last 3.5 years are included
within Section 7.
• Given the excellence of the effluent water quality discharged from the facility as
validated by the empirical data required by the current NPDES permit, Charlotte Water
Charlotte Water 5200 Brookshire Blvd, Charlotte, NC 28216 charlottewater.org
4d? Operated by the City of Charlotte

does not see the justification in being required to add the following Table A pollutants
to our monitoring requirements: COD, BOD and TOC.
Since ferrous sulfate is not currently being utilized in the treatment process, we
respectfully ask that quarterly Total Iron monitoring be removed from the permit
sampling requirements.
If you have any questions, please contact Dave Banick at 704-634-9104 or Gabe Sasser at 704-
507-5267.

Definitions
The legal definitions of all key terms used in these instructions and
Form 2C are in the "Glossary' at the end of the "General
Instructions" in Form 1.
Line -by -Line Instructions
Section 1.Outfall Location
Item 1.1. Identify each of the facility's outfall structures by number.
For each ouffall, specify the latitude and longitude to the nearest
15 seconds and name of the receiving water. The application form
provides reporting space for three outfalls. If your facility has more
than this number, attach additional sheets as necessary. The
location of each outfall (i.e., where the coordinates are collected)
shall be the point where the discharge is released into a water of
the United States. Latitude and longitude coordinates may be
obtained in a variety of ways, including use of hand held devices
(e.g., a GPS enabled smartphone), internet mapping tools (e.g.,
https://mynasadata.larc.nasa.gov/latitudelongitude-finder/),
geographic information systems (e.g., ArcView), or paper maps
from trusted sources (e.g., U.S. Geological Survey or USGS).For
further guidance, refer to
http://www.epa.gov/geospatial/latitudelongitude-data-standard.
Section 2. Line Drawing
Item 2.1. Attach a line drawing showing water flow through your
facility, from intake to discharge. Indicate the sources of intake
water (e.g., city, well, stream, other); operations contributing
wastewater to the effluent including process and production areas,
sanitary flows, cooling water, and stormwater runoff; and treatment
units labeled to correspond to the more detailed descriptions under
Section 3. You may group similar operations into a single unit.
Construct a water balance on the line drawing by showing average
flows (specify units) between intakes, operations, treatment units,
and ouffalls. Show all significant losses of water to products, the
atmosphere, and discharge. You should use actual measurements
wherever available; otherwise use your best estimate. If you cannot
determine a water balance for your activities (such as mining
activities), provide a pictorial description of the nature and amount
of any sources of water and any collection and treatment measures.
An example of an acceptable line drawing is provided in Exhibit
2C-1 at the end of these instructions.
Section 3. Average Flows and Treatment
Item 3.1. For each outfall identified under Item 1.1, provide the
following information: (1) all processes, operations, or production
areas that contribute wastewater to the effluent for the outfall,
including process wastewater, sanitary wastewater, cooling water,
and stormwater runoff; (2) average flow of wastewater contributed
by each operation in million gallons per day (mgd); (3) a description
of the treatment unit (including size of each treatment unit, flow rate
through each treatment unit, retention time, etc.); (4) the applicable
treatment code(s) from Exhibit 2C-2 (see end of instructions); and
(5) the ultimate disposal of any solid or fluid wastes that are not
discharged to the receiving water. You may describe processes,
operations, or production areas in general terms (e.g., "dye -making
reactor" or "distillation tower"). You may estimate the average flow
of point sources composed of stormwater; however, you must
2C-1

FORM 2C—INSTRUCTIONS CONTINUED
indicate the basis of the rainfall event and the method of estimation.
Add additional sheets as necessary.
Item 3.2. Answer whether you are applying for an NPDES permit to
operate a privately owned treatment works. If yes, continue to Item
3.3. If no, skip to Section 4.
Item 3.3. Attach a list to your application that includes the identity of
each user of the treatment works, then answer "Yes' to Item 3.3.
Section 4. Intermittent Flows
Item 4.1. Answer "Yes' or "No" to indicate whether any of the
discharges you described in Sections 1 and 3 of Form 2C are
intermittent or seasonal, except for stormwater runoff, spillage, or
leaks. An intermittent discharge is one that is not continuous. A
continuous discharge is one that occurs without interruption during
the operating hours of the facility, except for infrequent shutdowns
for maintenance, process changes, or other similar activities. A
discharge is seasonal if it occurs only during certain parts of the
year. If yes, continue to Item 4.2. If no, skip to Section 5.
Item 4.2. By relevant outfall number, identify each operation that
has intermittent or seasonal discharges. Indicate the average
frequency (days per week and months per year), the long-term
average and maximum daily flow rates in mgd, and the duration of
the intermittent or seasonal discharges. Base your answers on
actual data if available. Otherwise, provide your best estimate.
Report the average of all daily values measured during days when
the discharge occurred for "Long -Term Average," and report the
highest daily value for "Maximum Daily."
Section 5. Production
Item 5.1. Indicate whether any effluent limitation guidelines (ELGs)
promulgated under Section 304 of the Clean Water Act (CWA)
apply to your facility. If yes, continue to Item 5.2. If no, skip to
Section 6. All ELGs promulgated by EPA appear in the Federal
Register and are published annually in 40 CFR Subchapter N. An
ELG applies if you have any operations contributing process
wastewater in any subcategory covered by a Best Practicable
Control Technology Currently Available (BPT), Best Conventional
Pollutant Control Technology (BCT), or Best Available Technology
Economically Achievable (BAT) guideline. If you are unsure
whether you are covered by a promulgated ELG, consult your
NPDES permitting authority (see Exhibit 1-1 of the "General
Instructions" of Form 1). You must check "Yes' if an applicable ELG
has been promulgated, even if the ELG is being contested in court.
If you believe that a promulgated ELG has been remanded for
reconsideration by a court and does not apply to your operations,
you may answer "No" to Item 5.1 and skip to Section 6.
Item 5.2. Complete Item 5.2 by indicating the applicable ELG
category, ELG subcategory, and corresponding regulatory citation.
See the example below.

Item 5.3. Indicate if the limitations in the applicable ELGs are
expressed in terms of production or other measure of operation. For
operational parameter, it is expressed in terms of production (e.g.,
"pounds of biological oxygen demand per cubic foot of logs from
which bark is removed," or "pounds of total suspended solids per
megawatt hour of electrical energy consumed by smelting
furnace"). An example of an ELG not expressed in terms of a
measure of operation is one that limits the concentration of
pollutants. If yes, continue to Item 5.4. If no, skip to Section 6.
Item 5.4. Indicate the operations, products, or materials produced
at the facility for each outfall. For each operation, product, or
material produced, denote the quantity produced per day using the
measurement units specified in the applicable ELG. The NPDES
permitting authority will use the production information to apply
ELGs to your facility. You may not claim that the production
information you submit is confidential. You do not need to indicate
how you calculated the reported information. The production figures
provided must be based on a reasonable measure of actual daily
production, not on design capacity or on predictions of future
operations. To obtain alternate limits under 40 CFR 122.45(b)(2)(ii),
you must define your maximum production capability and
demonstrate to the NPDES permitting authority that your actual
production is substantially below maximum production capability
and that there is a reasonable potential for an increase above
actual production during the duration of the permit.
Section 6. Improvements
Item 6.1. Indicate if you are required by any federal, state, or local
authority to meet an implementation schedule for constructing,
upgrading, or operating wastewater treatment equipment or
practices or any other environmental programs that could affect the
discharges described in your application. The requirements include,
but are not limited to, permit conditions, administrative enforcement
orders, enforcement compliance schedule letters, stipulations, court
orders, and grant or loan conditions. If yes, continue to Item 6.2. If
no, skip to Item 6.3.
Item 6.2. Briefly identify and describe each applicable project (e.g.,
consent decree, enforcement order, or permit condition). For each
condition, specify the affected outfall number(s), the source(s) of
the discharge, the projected final compliance date, and the
required final compliance date.
Item 6.3.OPTIONAL ITEM. If desired, attach descriptions of any
additional water pollution control programs (or other environmental
projects that could affect your discharges) that are now underway
or planned. Indicate in your attachments whether each program is
actually underway or is planned, and indicate your actual or
planned schedule for construction.
Section 7. Effluent and Intake Characteristics
Items 7.1 to 7.17. These items require you to collect and report
data for the parameters and pollutants listed in Tables A through E,
located at the end of Form 2C. The instructions for completing the
tables are table -specific in addition to the criteria for determining
who should complete them. In general, the following conditions
apply:

Important note: Read the "General Instructions for Reporting,
Sampling, and Analysis" on pages 2C-5 and 2C-6 before
completing Section 7 and Tables A through E.
Item 7.1 and Table A. All applicants must report at least one
analysis for each conventional and non -conventional pollutant listed
in Table A for each outfall (one table per outfall). This includes
outfalls discharging only noncontact cooling water or stormwater
runoff. However, at your request, the NPDES permitting authority
may waive the requirement to test for one or more of the listed
pollutants for specific outfalls, upon a determination that available
information is adequate to support issuance of your NPDES permit
with less stringent reporting requirements. You may also request a
waiver from your NPDES permitting authority for one or more of the
Table A pollutants for your industry category or subcategory.
Indicate whether you are requesting a waiver in response to Item
7.1. If yes, continue to Item 7.2. If no, skip to Item 7.3.
Item 7.2. Specify the outfalls for which you are requesting a waiver.
Next, indicate on Table A for the applicable outfalls the pollutants
for which the waiver is being requested. Attach your waiver request
and supporting information to your completed Form 2C.
Item 7.3. Test your effluent from each outfall for each pollutant
listed in Table A for which you have not requested a waiver. You
may also conduct optional tests of your intake water for the Table A
pollutants. See the "General Instructions for Reporting, Sampling,
and Analysis" on pages 2C-5 and 2C-6 for further information.
Item 7.4 and Table B. This item asks whether any of the facility's
processes that contribute wastewater fall into one or more of the
primary industry categories listed in Exhibit 2C-3. If you are
applying for a permit for a privately owned treatment works,
determine your testing requirements based on the industrial
categories of your contributors. This exercise is simply to determine
your testing requirements only. You are not giving up your right to
challenge your inclusion in the category determined for testing (e.g.,
for deciding whether an ELG is applicable) before your permit is
issued. If yes, continue to Item 7.5. If no, skip to Item 7.8.
Complete a separate Table B for each outfall. Section 1 of Table B
lists toxic metals, cyanide, and total phenols. Sections 2 through 5
of Table B list the pollutants in each of the gas
chromatography/mass spectrometry (GC/MS) fractions. Note that
inclusion of total phenols in Section 1 of Table B does not mean
that EPA is classifying the group as toxic pollutants.
Item 7.5. Because you indicated in Item 7.4 that the facility's
processes contribute wastewater that falls into one or more of the
primary industry categories, check "Testing Required" for all toxic
metals, cyanide, and total phenols in Section 1 of Table B. Answer
"Yes" to Item 7.5 once you have completed this task.
Item 7.6. Because you indicated in Item 7.4 that the facility's
processes contribute wastewater that falls into one or more of the
primary industry categories, list the primary industry categories
applicable to your facility. Next, review Exhibit 2C-3 to determine
whether testing is required and for which GC/MS fraction(s): volatile
compounds, acid compounds, base/neutral compounds, and
pesticides. Check the applicable boxes for each GC/MS fraction
requiring testing.
Item 7.7. For each of the required GC/MS fractions, check "Testing
Required" for each of the pollutants in the required fraction in
Sections 2 through 5 of Table B. Answer "Yes" to Item 7.7 once you
have completed this task.
Item 7.8 and Sections 1 through 5 of Table B. For all other cases
(secondary industries, nonprocess wastewater outfalls, and
nonrequired GC/MS fractions) and remaining pollutants, check
"Believed Present" or "Believed Absent" in Sections 1 through 5 of
Table B to indicate whether you have reason to believe that any of
the pollutants listed are discharged from your outfalls. Answer "Yes"
to Item 7.8 after you have completed this step.
Item 7.9 and Section 1 of Table B. For each pollutant you know or
have reason to believe is present in your discharge from each
applicable outfall in concentrations of 10 parts per billion (ppb) or
greater, you must report quantitative data. For every pollutant
expected to be discharged in concentrations less than 10 ppb, you
must submit quantitative data or briefly describe the reasons the
pollutant is expected to be discharged. For pollutants in intake
water, see the discussion under "General Instructions for Reporting,
Sampling, and Analysis" below. Answer "Yes" to Item 7.9 once you
have completed Section 1 of Table B.
Item 7.10. This item asks if you qualify as a "small business." If so,
you are exempt from submitting quantitative data for the organic
toxic pollutants on Table B (Sections 2 through 5). You still must
indicate, though, whether you believe any of the pollutants listed in
Sections 1 through 5 are present in your discharge per the
Instructions at Item 7.8 above.
You can qualify as a small business in two ways: (1) If your facility
is a coal mine and if your probable total annual production is less
than 100,000 tons per year, you may submit past production data
or estimated future production (such as a schedule of estimated
total production under 30 CFR 795.14(c)) instead of conducting
analyses for the organic toxic pollutants. (2) If your facility is not a
coal mine and if your gross total annual sales for the most recent
three years average less than $100,000 per year (in second
quarter 1980 dollars), you may submit sales data for those years
instead of conducting analyses for the organic toxic pollutants.
The production or sales data must be for the facility that is the
source of the discharge. The data should not be limited to
production or sales for the process or processes that contribute to
the discharge, unless those are the only processes at your facility.
2C-3

FORM 2C—INSTRUCTIONS CONTINUED
For sales data, in situations involving intra-corporate transfer of
goods and services, the transfer price per unit should approximate
market prices for those goods and services as closely as possible.
Sales figures for years after 1980 should be indexed to the second
quarter of 1980 by using the gross national product price deflator
(second quarter of 1980 = 100). This index is available online from
the U.S. Department of Commerce, Bureau of Economic Analysis
at http://bea.gov/national/pdf/SNTables.pdf.
If you qualify as a small business according to the criteria above,
answer "Yes" to Item 7.10. Check the box at the top of Table B to
show that you are not required to submit quantitative data for the
organic toxic pollutants (Sections 2 through 5 of Table B), then
skip to Item 7.12. Otherwise, answer "No" and continue to Item
7.11.
Item 7.11 and Sections 2 through 5 of Table B. Unless you
qualify as a small business (see Item 7.10), you must provide
quantitative data for all pollutants for which you marked "Testing
Required" in Sections 2 through 5 of Table B. You must also
provide quantitative data for all pollutants you marked as "Believed
Present" in Sections 2 through 5 of Table B if you discharge those
pollutants in concentrations of 10 ppb or greater, except for
acrolein, acrylonitrile, 2,4-dinitrophenol, and 2-methyl-4,6-
dinitrophenol. If you discharge any of the four latter pollutants in
concentrations of 100 ppb or greater, you must report quantitative
data. If you discharge the pollutants in Sections 2 through 5 of
Table B less than these thresholds (i.e., <100 ppb for acrolein,
acrylonitrile, 2,4-dinitrophenol, and 2-methyl-4,6-dinitrophenol and
<10 ppb for all others), you must submit quantitative data or briefly
describe the reasons the pollutant is in your discharge.
For pollutants in intake water, see the discussion under "General
Instructions for Reporting, Sampling, and Analysis" on pages
2C-5 and 2C-6 for further information.
Once you have completed these tasks, answer "Yes" to Item 7.11.
Item 7.12 and Table C. For each outfall (including outfalls
containing only noncontact cooling water or stormwater runoff),
indicate whether you know or have reason to believe that any of
the pollutants listed on Table C are present in your discharge. If
so, mark the box in the "Believed Present" column for each
applicable pollutant. If not, mark the box in the "Believed Absent"
column for each applicable pollutant. Answer "Yes" to Item 7.12
once you have completed the required task for each outfall.
Item 7.13 and Table C. You are required to report quantitative
data for any Table C pollutants that are directly limited in an
applicable ELG or are indirectly limited in an applicable ELG
through an expressed limitation on an indicator (e.g., use of total
suspended solids (TSS) as an indicator to control the discharge
of iron and aluminum). For all other pollutants that you marked as
"Believed Present," you must either report quantitative data or
briefly describe the reasons the pollutant is expected to be
discharged.
For pollutants in intake water, see the discussion under "General
Instructions for Reporting, Sampling, and Analysis" on pages
2C-5 and 2C-6 for further information.
Answer "Yes" to Item 7.13 when you have fully completed the
tasks associated with Table C and Items 7.12 and 7.13 above.
Item 7.14 and Table D. For each outfall, indicate if you believe that
any pollutant listed in Table D is "Believed Present" or "Believed
Absent" in your facility's effluent. Check the boxes in the applicable
columns on Table D next to each pollutant. For every pollutant
believed present, you must briefly describe the reasons the
pollutant is expected to be discharged and report any quantitative
data you have for that pollutant. Note that you are not required to
perform analytical tests for any of the Table D pollutants at this time.
However, if you have prior test results, you must report them.
Item 7.15. Answer "Yes" to this Item when you have completed
Table D.
Under 40 CFR 117.12(a)(2), certain discharges of hazardous substances
(listed in Exhibit 2C-4 at the end of these instructions) may be exempted from
the requirements of Section 311 of the CWA, which establishes reporting
requirements, civil penalties, and liability for cleanup costs for spills of oil and
hazardous substances. A discharge of a particular substance can be exempted
if the origin, source, and amount of the discharged substances are identified in
the NPDES permit application or in the permit, if the permit contains a
requirement for treatment of the discharge, and if the treatment is in place.
Exemptions are allowed from the requirements of CWA Section 311.
Applications for exemptions must set forth the following information:
1. The substance and the amount of each substance that may be discharged.
2. The origin and source of the discharge of the substance.
3. The treatment to be provided for the discharge by:
a. An onsite treatment system separate from any treatment system
treating your normal discharge;
b. A treatment system designed to treat your normal discharge and that is
additionally capable of treating the amount of the substance identified
under paragraph 1 above; or
c. Any combination of the above.
See 40 CFR 117.12(a)(2) and (c) or contact your NPDES permitting authority
for further information on exclusions from CWA Section 311.
Item 7.16. Indicate whether:
• Your facility uses or manufactures 2,4,5-trichlorophenoxy
acetic acid (2,4,5-T); 2-(2,4,5-trichlorophenoxy) propanoic acid
(Silvex, 2,4,5-TP); 2-(2,4,5-trichlorophenoxy) ethyl 2,2-dichloro-
propionate (Erbon); 0,0-dimethyl 0-(2,4,5-trichlorophenyl)
phosphorothioate (Ronnel); 2,4,5,-trichlorophenol (TCP); or
hexachlorophene (HCP).
• You know or have reason to believe that 2.3.7,8-
tetrachlorodibenzo-p-dioxin (TCDD) is or may be present in an
effluent.
If yes, continue to Item 7.17. If no, skip to Section 8.
Item 7.17 and Table E. If you answered "Yes" to Item 7.16, you
must report qualitative data, generated using a screening procedure
not calibrated with analytical standards, for TCDD. Your screening
analyses must be performed using gas chromatography with an
electron capture detector. A TCDD standard for quantitation is not
required. Describe the results of your screening analysis (e.g., "no
measurable baseline deflection at the retention time of TCDD" or "a
measurable peak within the tolerances of the retention time of
TCDD.") on Table E. The NPDES permitting authority may require
you to perform a quantitative analysis if you report a positive result.
Answer "Yes" to Item 7.17 when you have completed Table E
2C-4

of the tables and any associated attachments.
You may report some or all of the required data by attaching
separate sheets of paper instead of completing Tables A through E
for each of your outfalls so long as the sheets contain all of the
required information and are similar in format to Tables A through
E. For example, you may be able to print a report in a compatible
format from the data system used in your GC/MS analysis
completed under Table B.
Table A requires you to report at least one analysis for each
pollutant listed. Tables B through D require you to report analytical
data in two ways. For some pollutants, you may be required to
check the box in the "Testing Required" column and test and report
the levels of the pollutants in your discharge whether or not you
expect them to be present in your discharge. For all other
pollutants, you must check the box in either the 'Believed Present'
or "Believed Absent' columns based on your best estimate and test
for those you believe to be present (with some exceptions). Base
your determination that a pollutant is present in or absent from your
discharge on your knowledge of your raw materials, maintenance
chemicals, intermediate and final products and byproducts, and any
previous analyses known to you of your effluent or similar effluent.
For example, if you manufacture pesticides, you should expect
those pesticides to be present in contaminated stormwater runoff.
If you would expect a pollutant to be present solely because of its
presence in your intake water, you must mark 'Believed Present'
but you are not required to analyze for that pollutant. Instead, mark
an "X" in the long-term average value of the "Intake" column;
optionally, you may instead provide intake data.
Reporting of Effluent Data
Report sampling results for all pollutants in Tables A through C as
concentration and total mass, except for flow, temperature, pH,
color, and fecal coliform organisms. If you are reporting
quantitative data under Table D, report concentration only.
Flow, temperature, pH, color, and fecal coliform organisms must be
reported as mgd, degrees Celsius (°C), standard units, color units,
and most probable number per 100 milliliters (MPN/100 mL),
respectively. Use the following abbreviations in the columns
requiring "units" in Tables A through D.
Concentration
Mass
ppm = parts per million
Ibs = pounds
mg/L = milligrams per liter
ton = tons (English tons)
ppb = parts per billion
mg = milligrams
pg/L = micrograms per liter
g = grams
MPN = most probable number per
kg = kilograms
100 milliliters
T = tonnes (metric tons)
• An applicable, promulgated ELG specifies the limitation for
the metal in dissolved, valent, or total form;
All approved analytical methods for the metal inherently
measure only its dissolved form (e.g., hexavalent chromium);
or
• The permitting authority has determined that in establishing
case -by -case limitations it is necessary to express the
limitations of the metal in dissolved, valent, or total form to
carry out the provisions of the CWA.
Note that you are not required to complete the "Maximum Monthly
Discharge" and the "Long -Term Average Daily Discharge" columns
of Tables A through C; however, these fields should be completed
if data are available.
If you measure only one daily value, complete the "Maximum Daily
Discharge" columns of the tables and enter 1" in the "Number of
Analyses" columns. The NPDES permitting authority may require
additional analyses to further characterize your discharges.
For composite samples, the daily value is the total mass or
average concentration found in a composite sample taken over the
operating hours of the facility during a 24-hour period. For grab
samples, the daily value is the arithmetic or flow -weighted total
mass or average concentration found in a series of at least four
grab samples taken over the operating hours of the facility during a
24-hour period.
If you measure more than one daily value for a pollutant and those
values are representative of your wastestream, you must report
them. You must describe your method of testing and data analysis.
When an applicant has two or more outfalls with substantially
identical effluents, the NPDES permitting authority may allow the
applicant to test only one outfall and report those quantitative data
as applying to the substantially identical outfall. If the permitting
authority grants your request, attach a separate sheet to the
application form identifying the outfall tested and describing why the
other outfall(s) are substantially identical.
Reporting of Intake Data
You are not required to report data under the "Intake" columns of
Tables A through C unless you wish to demonstrate your eligibility
for a "net' effluent limitation for one or more pollutants in Tables A
through C (i.e., an effluent limitation adjusted by subtracting the
average level of the pollutant(s) present in your intake water).
NPDES regulations allow net limitations only in certain
circumstances. To demonstrate your eligibility, under the "Intake"
columns report the average of the results of analyses of your intake
water and discuss the requirements for a net limitation with your
NPDES permitting authority. If your water is treated before use, test
the water after it has been treated.
2C-5

General Instructions for Reporting, Sampling, and Analysis Continued
Sampling
The collection of samples for the reported analyses should be
supervised by a person experienced in performing sampling of
industrial wastewater. You may contact your NPDES permitting
authority for detailed guidance on sampling techniques and for
answers to specific questions. See Exhibit 1-1 of Form 1 for
contact information. Any specific requirements in the applicable
analytical methods —for example, sample containers, sample
preservation, holding times, and the collection of duplicate
samples —must be followed.
The time when you sample should be representative of your normal
operation, to the extent feasible, with all processes that contribute
wastewater in normal operation, and with your treatment system
operating properly with no system upsets. Collect samples from the
center of the flow channel, where turbulence is at a maximum, at a
site specified in your present NPDES permit, or at any site
adequate for the collection of a representative sample.
Grab samples must be used for pH, temperature, cyanide, total
phenols, residual chlorine, oil and grease, fecal coliform (including
E. coh), and enterococci (previously known as fecal streptococcus
at 40 CFR 122.26(d)(2)(iii)(A)(3)), and volatile organic compounds.
For all other pollutants, a 24-hour composite sample, using a
minimum of four grab samples, must be used unless specified
otherwise at 40 CFR 136. However, a minimum of one grab
sample may be taken for effluents from holding ponds or other
impoundments with a retention period greater than 24 hours.
For stormwater discharges, a minimum of one to four grab
samples must be taken, depending on the duration of the
discharge. One grab sample must be taken in the first hour (or
less) of discharge, with one more grab sample (up to a minimum of
four) taken in each succeeding hour of discharge for discharges
lasting four hours or more.
Except for stormwater discharges, the NPDES permitting authority
may waive composite sampling requirements for any outfall for
which you demonstrate that use of an automatic sampler is
infeasible and that the minimum of four grab samples will be
representative of your discharge. Results of analyses of individual
grab samples for any parameter may be averaged to obtain the
daily average. Grab samples that are not required to be analyzed
immediately may be composited in the laboratory, if the container,
preservation, and holding time requirements are met and if sample
integrity is not compromised during compositing. See Table II at 40
CFR 136.3 for further information.
A grab sample is an individual sample of at least 100 milliliters
collected at a randomly chosen time over a period not exceeding
15 minutes.
A composite sample is a combination of at least eight sample
aliquots of at least 100 milliliters, collected at periodic intervals
during the operating hours of a facility over a 24-hour period. The
composite must be flow proportional; either the time interval
between each aliquot or the volume of each aliquot must be
proportional to either the stream flow at the time of sampling or the
total stream flow since the collection of the previous aliquot.
Aliquots may be collected manually or automatically. For "GC/MS
Fraction —Volatile Compounds" in Table B, aliquots must be
combined in the laboratory immediately before analysis. Four
(rather than eight) aliquots or grab samples should be collected for
this fraction. These four samples should be collected during actual
hours of discharge over a 24-hour period and need not be flow
proportioned. Only one analysis is required.
Use of Historical Data
Existing data may be used, if available, in lieu of sampling
conducted solely for the purposes of this application, provided that:
all data requirements are met; sampling was performed, collected,
and analyzed no more than 4.5 years prior to submission; all data
are representative of the discharge; and all available representative
data are considered in the values reported.
Analysis
Except as specified below, all required quantitative data shall be
collected in accordance with sufficiently sensitive analytical
methods approved under 40 CFR 136 or required under 40 CFR
chapter I, subchapter N or 0. A method is "sufficiently sensitive"
when:
• The method minimum level (ML) is at or below the level of the
applicable water quality criterion for the measured pollutant or
pollutant parameter.
• The method ML is above the water quality criterion, but the
amount of the pollutant or pollutant parameter in the facility's
discharge is high enough that the method detects and
quantifies the level of the pollutant or pollutant parameter in
the discharge.
• The method has the lowest ML of the analytical methods
approved under 40 CFR 136 or required under 40 CFR
chapter I, subchapter N or 0 for the measured pollutant or
pollutant parameter.
Consistent with 40 CFR 136, you may provide matrix- or sample -
specific MLs rather than the published levels. Further, where you
can demonstrate that, despite a good faith effort to use a method
that would otherwise meet the definition of "sufficiently sensitive,"
the analytical results are not consistent with the quality assurance
(QA)/quality control (QC) specifications for that method, then the
NPDES permitting authority may determine that the method is not
performing adequately and the NPDES permitting authority should
select a different method from the remaining EPA -approved
methods that is sufficiently sensitive consistent with 40 CFR
122.21(e)(3)(i). Where no other EPA -approved methods exist, you
must select a method consistent with 40 CFR 122.21(e)(3)(ii).
When there is no analytical method that has been approved under
40 CFR 136; required under 40 CFR chapter I, subchapter N or 0,
and is not otherwise required by the NPDES permitting authority,
you may use any suitable method but shall provide a description of
the method. When selecting a suitable method, other factors such
as a method's precision, accuracy, or resolution, may be
considered when assessing the performance of the method.

Treatment Process Synopsis
Water Treatment Process
Raw water supplied to the Dukes plant is treated with potassium permanganate and powdered
activated carbon as needed. Aluminum sulfate is added at the head works of the plant. The
water then passes through three stages of flocculation before entering the sedimentation
basins. Chlorine, to begin disinfection, is added just before filtration. Following filtration, lime,
fluoride and chlorine are added to the filtered water prior to flowing to clearwells for onsite
storage. In the future, there are plans to apply chlorine dioxide in place of potassium
permanganate into the raw water of Lake Norman before entering the treatment process,
however, no implementation date has been set and construction has not begun. Ferrous sulfate
may be applied in the future as well in conjunction with chlorine dioxide. Since ferrous sulfate is
not currently being utilized in the treatment process, we respectfully ask that quarterly Total
Iron monitoring be removed from the permit sampling requirements.
Filter Backwash, Residuals and Sludge Management Process
Filter backwash water is discharged to an EQ basin. The EQ basin pumps water to a clarifier.
Solids are generated from the water treatment process, consisting of alum residuals. The solids
that settle on the bottom of the clarifier are discharged to a thickener before being directed to a
holding lagoon. Solids generated from the sedimentation basins utilized in the water treatment
process are also discharged to a gravity thickener. From the bottom of the thickener solids are
sent to a holding lagoon. Solids from the holding lagoon are removed by a contractor
(Synagro) and land applied according to permit requirements (WQ 0000057). We also have the
ability to tanker the liquid residuals to a belt press prior to land application or land fill disposal.
Clear water from the top surface of the clarifier flows over a weir and into a de -chlorination
chamber where sodium bisulfite is added before being directed to the NPDES discharge point
(Outfall 1). Supernatant from the lagoon is intermittently discharged to the receiving stream.

Subject: NPDES Permit Renewal Application
Lee S. Dukes Water Treatment Plant - NPDES Permit # NCO084387
Waiver Request for Table A Pollutants
Mr. Corporon,
Charlotte Water respectfully requests a waiver for monitoring several of the parameters
included in the Table A list of contaminants. COD, BOD and TOC have never been constituents
required to be monitored at this location. The current permit requires weekly monitoring for
Flow, Total Suspended Solids, pH, Total Residual Chlorine and Turbidity. Required quarterly
monitoring includes the following parameters: Aluminum, Fluoride, Phosphorus, Total Kjeldahl
Nitrogen, Nitrate, Nitrite, Total Nitrogen and Chronic WET Testing for Ceriodaphnia dubia.
Lee S Duke Water Treatment Plant is categorized as a conventional technology water treatment
plant [utilizing coagulation, flocculation, sedimentation, and filtration] with discharge of
wastewaters from media filter backwash and sedimentation basins to freshwater. Considering
the type of wastewaters produced, Charlotte Water does not see the justification in being
required to add COD, BOD and TOC as additional monitoring parameters, given the excellence
of the effluent water quality leaving the facility as validated by the empirical data required by
the current NPDES permit. Please consider granting Charlotte Water a waiver for these
parameters.
If you have any questions, please contact Dave Banick at 704-634-9104 or Gabe Sasser at 704-
507-5267.
Sincerely
Gabe Sasser

Hi Wes,
Hope you are doing well. Thanks for providing clarification and confirming the requirements for me. Very much
appreciate your help there. We can certainly provide the 3 years of data for the parameter and flow questions in the
application. Are you good with the last three complete calendar years (2021, 2020 and 2023)? Thanks and take care.

Good Morning,
It has been confirmed that you only report what you were required to sample in your permit and you can put "NA"
for those parameters listed but not required to sample for. You will still need to check whether or not you believe
the listed parameters are in the waste stream (Presence or absence) for the parameters in Tables B and C. You
need a minimum of three years of data to use in the application.

Good afternoon Gabe,
I'm in the process of confirming but you do not have to sample for the parameters listed in the renewal application
if your permit does not require you to .... for your type of permit anyway. I let you know once that is confirmed. You
would mark "NA" for each applicable parameter.

Hi Sydney,
I hope you are doing well. In the past I have worked with Derek on permit renewals and he has directed me to you for
the latest updates. With the new permit renewal form being much more complex the old form can you help me with my
questions below regarding completion of the permit for Dukes WTP (Permit # NC0084387). Thanks and take care.

Gabe,
It has been a few years since I worked with WTPs. Please contact Sydney Deuterman. She would be best
to help with these questions about WTPs. Also Joe Corporon is currently the point of contact for
Mooresville Regional office permitting questions for Compliance and Expeditated Permitting. I am coping
them on this message.

Hi Derek,
I hope you are doing well. In working together in the past regarding renewal of Charlotte Water's NPDES permits at
both Franklin and Dukes WTPs, I am in the process of preparing both permit applications in the coming weeks. I am
currently focused on Dukes (NC0084387) as the expiration of the current permit occurs on February 281h, 2025. As
points of reference, I have attached the previous permit renewal application for Dukes WTP (Short Form C - dated
9/25/19) along with the existing NPDES permit. Understanding the 180-day submittal requirement ahead of the
expiration date, I plan to submit the application for Dukes sometime near the end of August. With the new format
(Application Form 2C) being quite a bit more involved than the short form 2C we are accustomed to, I wanted to reach
out to you with several questions:
All the data I have is centered around the current permit requirements. Several different groups of
contaminants are included on the new permit application (Groups A, B, C and D). For many of the constituents
within those groupings, we have limited or no data. Group by group, I have the following comments:
• Group A: Per the existing Dukes WTP NPDES permit, we are required to monitor for the majority of
these parameters, but not for BOD, COD and TOC, so I have not data for these constituents. Are results
for these parameters required before submitting the application?
• Group B: Per the existing Dukes WTP NPDES permit, we are not required to monitor for any of the
parameters included on this list and therefore don't have any monitoring data for these parameters.
• Group C: Per the existing Dukes WTP NPDES permit, we only monitor for Total Chlorine Residual,
Fluoride, Nitrate/Nitrite, Total Nitrogen, Phosphorus and Aluminum. We are not required to monitor for
any other parameters.
• Group D: Per the existing Dukes WTP NPDES permit, we are not required to monitor for any of the
parameters included on this list and therefore don't have any monitoring data for these parameters.
2. Is providing a years -worth of analytical data for the required parameters representative for the parameters we
currently monitor for? Our results are very consistent.
I feel good about our process flow schematic, (line drawing) biosolids management plan and facility map. This
application is quite different from what we are accustomed to and I'm just reaching out for some guidance. Thanks and
take care.
