Subject: Final NPDES Permit Renewal
Permit NCO024970
McAlpine Creek WWMF
Mecklenburg County
Facility Class IV
SIC Code 4952
Dear Ms. Jarrell:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached 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 U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
The following changes were made to the draft permit sent to you on May 31, 2017:
• Footnote 6 in Section A. (1) concerning effluent hardness samples coinciding with
sampling for metals has been removed. Charlotte Water samples at a frequency that
provides ample hardness data needed to evaluate the new dissolved metals standards.
• The mercury minimization plan (MMP) in Section A. (10) shall be developed by March
30, 2018 and the condition has been updated to reflect that date and the current website
link.
• A technical correction has been made to remove the statement "there shall be no
discharge of floating solids or visible foam in other than trace amounts" from the draft
Special Condition A. (1).
• A technical correction has been made to the limit for total residual chlorine to include the
weekly average limit as specified in the previous permit. The weekly average limit for
total residual chlorine is 17 µg/L. The daily maximum limit for total residual chlorine is
28 gg/L.

• Instream monitoring for total copper in McAlpine Creek has been reduced to a quarterly
frequency. Total copper and total chromium has also been reduced from monthly to a
quarterly frequency for Sugar Creek and Irwin Creek. Total copper has been reduced to a
quarterly frequency for Little Sugar Creek. These parameters were at levels below the
instream allowable concentration. The changes to Charlotte Water's instream monitoring
frequencies are reflected within this permit renewal for McAlpine Creek WWMF, Sugar
Creek WWTP, and Irwin Creek WWTP.
• Footnote 4 in Section A. (1) has been added in order to specify the current compliance
level for total residual chlorine.
• Footnote 6 in Section A. (1) has been included to provide clarification on McAlpine
Creek WWMF's monthly average total phosphorus limit.
The final permit maintains the following significant changes identified in the letter sent on
May 31, 2017:
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the
NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA
subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new
dissolved metal standards in all permits public noticed after April 6, 2016. The new
standards for most metals include acute standards. Further, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have
hardness -dependent equations. As a result, the NPDES Permitting Unit will need site-
specific effluent hardness data and instream hardness data, upstream of the discharge, for
each facility monitoring these metals in order to calculate permit limitations. Effluent
hardness and instream hardness sampling, upstream of the discharge, has been added to
this permit at a monitoring frequency of quarterly. See special condition A. (1) Effluent
Limitations and Monitoring Requirements for effluent sampling requirements. Instream
hardness sampling, upstream of discharges at stations MCI, IC1, and LSCI has been
included in Special Conditions A. (2), (3), and (5).
• The monitoring of mercury has been removed from Effluent Limitations and Monitoring
Requirements based on the TMDL evaluation. Sampling for mercury shall be conducted
during the 3 effluent pollutant scans [see Special Condition A. (9)].
• Special Condition A. (10) has been added to require a Mercury Minimization Plan
(MMP) based on the statewide mercury TMDL approved by EPA in 2012.
• The monitoring for copper and zinc has been removed based on the results of the RPA
which showed no reasonable potential to exceed water quality standards.
• Quarterly monitoring for total phenolic compounds has been added to this permit based
on the results of the reasonable potential analysis.
• Quarterly silver monitoring has been included in section A. (1) and should be sampled at
the Practical Quantitation Limit (PQL) of 1.0 gg/L. This metal is currently reported at
levels less than 5 µg/1 but the allowable discharge concentration for your facility is 0.061
µg/L. Therefore, the best your facility can do is sample silver down to the lower reporting
level of the procedure which is < 1.0 gg/L. If sampling and reporting do not show silver

Page 13
concentrations consistently < 1 µg/L, a limit will be added to the permit during the next
renewal.
• Footnote 3 in Special Condition A. (1) has been included regarding the reduction of
monitoring frequencies for CBOD5, TSS, NH3-N, and fecal coliform.
• Instream monitoring for zinc at stations MC1, upstream of McAlpine Creek, and MC2,
downstream in McAlpine Creek has been removed. Review of instream data shows that
instream values for zinc are consistently below the water quality standard.
• Effluent Pollutant Scan frequency has changed from annual to 3 times per permit cycle
[see A. (9)].
• Parameter characteristic codes have been added in Special Condition A. (1), A. (2), A.
(3), A. (4), and A. (5).
• An updated outfall map has been included.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted
and became effective on December 21, 2015. The requirement to begin reporting discharge
monitoring data electronically using the NC DWR's Electronic Discharge Monitoring
Report (eDMR) internet application has been added to your final NPDES permit. [see
Special Condition A. (11)]

Please note that the receiving stream is listed as impaired for benthos on North Carolina's 303(d)
2014 Impaired Waters List. Addressing impaired waters is a high priority with the Division, and
instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits
and the stream impairment can be attributed to your facility, then mitigative measures may be
required.
If any parts, measurement frequencies or sampling requirements contained in this 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 (6714 Mail Service Center, Raleigh, North Carolina 27699-
6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect
the legal requirements to obtain other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental permits that may be required.

A. (6) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)- 64 MGD
[I 5A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase H Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. The tests will be performed during the months of
March, June, September, and December. These months signify the first month of each three-month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained
during representative effluent discharge and shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR -1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT -
3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Water Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
Page 9 of 15

Permit NCO024970
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources 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, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.
A. (7) TOTAL PHOSPHORUS LIMIT
[NCGS 143-215.1 (b)]
As stipulated by the 2002 Settlement Agreement between Charlotte -Mecklenburg Utilities (CMU), the
South Carolina Department of Health and Environmental Control (SC DHEC) and the North Carolina
Division of Water Quality (NC-DWQ), now North Carolina Division of Water Resources, Charlotte
Water's McAlpine Creek WWMF, Sugar Creek WWTP and Irwin Creek WWTP must comply with a
combined 12 month rolling average limit of 826.0 lbs/day as of February 28, 2006. This limit is defined
as an effluent limit for total phosphorus from the total combined discharge from the three referenced
Charlotte Water wastewater treatment plants (based on a 12 -month rolling average). The methodology
for calculating the annual average is described in special condition A. (8).
A. (8) TOTAL PHOSPHORUS MONITORING
[NCGS 143-215.1 (b)]
The Permittee shall calculate a 12 -month rolling average mass loading as the sum of monthly loadings,
according to the following equations:
a) Monthly Average (lbs./day) = TP x Qw x 8.34
where:
TP = the arithmetic average of total phosphorus concentrations (mg/L) obtained via
composite samples (either daily, weekly, or monthly average values) collected during the
month
Qw = the average daily waste flow (MGD) for the month
8.34 = conversion factor, from (mg/L x MGD) to pounds
The 12 -month rolling average mass loading is defined as the sum of the monthly average loadings for the
previous 12 months inclusive of the reporting month:
12
b) 12 -Month Mass Loading (lbs./day)= LTPma =12 (inclusive of reporting month)
1
where:
TPma is defined as the total phosphorus monthly average mass loading (calculated above).
Page 10 of 15

Permit NCO024970
The monthly average and 12 -month average mass loadings shall be reported and submitted with the
discharge monitoring report for McAlpine Creek WWMF (NC0024970). The total phosphorus monthly
average mass loadings should be reported on the discharge monitoring report for the respective facility.
The Permittee shall report the total phosphorus concentration for each sample on the appropriate
discharge monitoring report for each facility. Reporting of and compliance with the phosphorus limit
shall be done on a monthly basis.
A. (9) EFFLUENT POLLUTANT SCAN
[NCGS 143-215.1 (b)]
The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below.
One scan must be performed in each of the following years: 2018, 2019, and 2020. Analytical methods
shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether
parameters are present in concentrations greater than applicable standards and criteria. Samples should
be collected with one quarterly toxicity test each year, and must represent seasonal variation [i.e., do not
sample in the same quarter every year]. Unless otherwise indicated, metals shall be analyzed as "total
recoverable."

on a form approved by the Director) by December 31 sl of each designated sampling year. The report
shall be submitted to the following address:
NC DEQ / DVM / Central Files, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617.
Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that
Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also
subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.210)(5)
and EPA Municipal Application Form 2A. The US EPA requires four (4) toxicity tests for a test
organism other than the test species currently required in this permit. The second species tests should be
conducted either quarterly for a 12 -month period prior to submittal of the permit renewal application, or
four tests performed at least annually in the four and one half year period prior to the application. The
second species tests must be multiple concentration (5 concentrations plus the control). These tests shall
be performed for acute or chronic toxicity, whichever is specified in this permit. POTWs performing
NPDES chronic Ceriodaphnia testing should perform chronic Fathead minnow testing. POTWs
performing NPDES acute Fathead Minnow testing should perform acute Ceriodaphnia testing. POTWs
performing NPDES chronic Mysid shrimp testing should perform chronic Silverside Minnow testing.
The second species toxicity test results shall be filed with the Aquatic Toxicology Branch at the
following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal
application to the NPDES Permitting Unit.
A. (10) MERCURY MINIMIZATION PLAN (MMP)
[NCGS 143-215.1 (b)]
The permittee shall develop and implement a mercury minimization plan during this permit term. The
MMP shall be developed by March 30, 2018, and shall be available for inspection on-site. A sample
MMP was developed through a stakeholder review process and has been placed on the Division website
for guidance (http://deq.nc.gov/about/divisions/water-resources/water-resources-permits/wastewater-
branch/npdes-wastewater-permits, under Model Mercury Minimization Plan). The MMP should place
emphasis on identification of mercury contributors and goals for reduction. Results shall be summarized
Page 12 of 15

Permit NCO024970
and submitted with the next permit renewal. Performance of the Mercury Minimization Plan will meet
the requirements of the TMDL (Total Maximum Daily Load) for mercury approved by USEPA on
October 12, 2012, unless and until a Waste Load Allocation specific to this facility is developed and this
NPDES permit is amended to require further actions to address the Waste Load Allocation.
A. (11) ELECTRONIC REPORTING OF MONITORING REPORTS
[NCGS 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)]
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section below.
Page 13 of 15

Permit NCO024970
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the perinittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: https://www federalregister.gov/documents/2015/10/22/2015-
24954/national-pollutant-discharge-elimination-system-npdes-electronic-reportingrule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such tune, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re -applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may
submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
Page 14 of 15

Permit NCO024970
http://deq.nc gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (I 1.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION
WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].

This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H 0903(b)(26)]
"Significant Industrial User" or "SIU"

the enteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pret_eatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge penmt, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU), or
6 Subject to approval under 15A NCAC 02H 0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
