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 1). The latest version of Parts II, III, and
IV are available at https://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]].

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 NPDE re ated facilities means the entity
(EPA or the state authorized by EPA to implement the NP S m)that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127. ) .
EPA plans to establish a website that will also li o e appropriate electronic reporting tool for
each type of electronic submission and for each state. tructio on how t a cess and use the
appropriate electronic reporting tool will ailable a . n ation on 's NPDES

the Division. Req s for temp a e c onic reporting waivers must be submitted in writing to
the Division for wri n pproval a 1 as .x (60) days prior to the date the facility would be
required under this pe i o begin u mitti g monitoring data and reports. The duration of a
temporary waiver shall n ceed y ars and shall thereupon expire. At such time, monitoring data
and reports shall be submitt ec nically to the Division unless the permittee re-applies for and is
granted a new temporary elect .c 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.

frequency as the pollutant scan until further notice by the Division.
• Parameter codes noted with"+"in the tables below may not currently be allowed in eDMR and will need to
be added by the eDMR administrator. Please submit requests to add parameters to the appropriate eDMR
contacts with the Division.
• Any analytes in the tables below that do not have an assigned parameter code are noted as"No Code". These
parameters shall be noted in the comments section of eDMR by n 'ng a analyte detected,the CAS
Registry No. and the reported concentration.
