Subject: Review of Permit Renewal DRAFT
NPDES Permit NCO089923
WWTP Class WPCS PC-1
Sewer Extension Dewatering
Baxter and McDowell Streets, Charlotte
Mecklenburg County
Mr. Deal:
In response to your request to renew the subject NPDES permit, received June 15, 2023, the
Division of Water Resources (DWR or the Division) hereby transmits this draft permit for your
review and comment. Please review this document carefully to ensure your understanding of the
permit limits and monitoring conditions, and to correct errors, if any.
Concurrent with this notification, the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Mecklenburg County area, as
required by the NPDES Program. Please provide your written comments, if any, to me via email
[e-mail]], or write to my attention care of NCDEQ / DWR / NPDES Program no
later than September 22, 2023, approximately 30 days after receiving this letter. Your written
comments are welcome, but they are not mandatory.
DWR understands that Charlotte Water (Charlotte) continues to advance traveling excavations to
install new sewer lines extending multiple city blocks, and that these excavations require dewatering.
Because of the traveling nature of these excavations, there remains the potential to encounter renewed
concentrations of contaminants of concern (COCs) known to be present as identified by previous NC
Brownfields studies and by Charlotte site investigations.
Our review to date of your treated effluent suggests that your current treatment system is
adequate to protect surface water quality in that we find no infractions of permit limits or
monitoring conditions. Our review included reasonable potential analyses (RPAs) of chlorinated
solvents, metals, and other volatile organic compounds to determine a potential to exceed water
quality standards, as applicable. Although we find no reasonable potential, DWR remains
concerned about unpredictable COC concentrations in traveling excavation.

Review of Permit Renewal DRAFT
Page 2 of 2
Acknowledging unpredictable contaminant concentrations, the Division will again require for
renewal the effluent parameters, limits, and monitoring conditions listed in your previous permit
[see section A. (1.)]. However, despite undetermined influent wastewaters, we are confident that
Charlotte's existing treatment system will continue to protect surface water quality. DWR has
therefore made only minimal changes to your permit for renewal to include updates to permit
text and your site location map.
The NPDES standard conditions (Parts II, III, and IV), are part of this permit but are not included
in this draft document (only cover letter, map, and Part I). The latest version of Parts II, III, and
IV are available at htWs://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
Following the mandatory 45-day public -comment period, the Division will review all pertinent
comments, if any, and take appropriate action prior to issuing an NPDES permit final. If you
have questions concerning this draft, please e-mail the undersigned [e-mail]].

A. (2.) ACUTE TOXICITY MONTHLY - MONITOR ONLY
[I5A NCAC 02B .0200 et seq.]
The Permittee shall conduct acute toxicity tests monthly using protocols defined as definitive in EPA
Document EPA-821-R-02-012 entitled "Methods for Measuring the Acute Toxicity of Effluents and
Receiving Waters to Freshwater and Marine Organisms." The monitoring shall be performed as a
Fathead Minnow (Pimephales promelas) 48-hour static test. Effluent samples for self -monitoring
purposes must be obtained during representative effluent discharge and shall be performed at the
NPDES permitted final effluent discharge below all waste treatment processes.
The parameter code for Pimephales promelas is TAA6C. All toxicity testing results required as part of
this permit condition will be entered on the Effluent Discharge Form (MR" 1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DWR Form AT-1 (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, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than0
days after the end of the reporting period foii.which the report is made.
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 there be no discharge of flow from the facility during any month, 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 any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality 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 follow-up testing to be completed no later than the last day of the month following
the month of the initial monitoring.

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 electronicoly using the internet. The eDMR system may be
accessed at: https:Hdeg.nc.gov/about/diyisions6whter-resources/edmr.
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
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
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 permittee 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.

NPDES Electronic Reporting Rule — Phase 2 Extension: EPA is proposing to extend the Phase 2
deadline from December 21, 2020 until at least December 21, 2023. The current compliance date
will be extended if the implementation date is extended as a final regulation change in the federal
register.
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 �o the appropriate electronic reporting tool for
each type of electronic submission and for each state` liistructionspn how to access and use the
appropriate electronic reporting tool will be available as wejl!Infofination on EPA's NPDES
