SIC 4952,Grade IV Facility
Dear Ms.Jarrell:
The Division of Water Resources staff has reviewed your May 31,2016 application for an
NPDES permit for a new Joe C.Stowe,Jr.Regional Water Resources Reclamation Facility.The
Division has made a tentative determination to issue the permit and is forwarding herewith a
draft permit for your review and comment.
At this time,we are submitting a notice for publication in the newspapers of general circulation
in Mecklenburg County,inviting public comment on the draft permit.The notice is scheduled 1
to bepublished on or about August 26,2019. Followinga 30-daycomment period,the Division
gu
will review allpertinent comments received and take appropriate action on the permit issuance.
Please provide any comments you have regarding the draft permit to this office,in writing,no
later than Monday,September 26,2019.Comments should be sent to my attention at either
NCDEQ/ DWR,WQ Permitting Section,1617 Mail Service Center,Raleigh,NC,27699-1617;or
at [e-mail].
The attached draft permit includes the cover pages,location map,and special conditions (Part I)
of the permit. Part I of the draft permit consists of the following special conditions:
• Effluent limitations and monitoring requirements;
• Instream monitoring requirements;
• Mercury minimization plan;
• Chronic toxicity permit limit;
• Effluent pollutant scan and 2nd species toxicity testing;
• Total nitrogen and total phosphorus limits;
• Nutrient allocations;
• Calculation and reporting of nutrient loads;and
• Electronic reporting of discharge monitoring reports.

Draft NPDES Permit NC0089630
Joe C.Stowe,Jr. Regional Water Resources Reclamation Facility
August 20,2019
The NPDES standard conditions (Parts II,III,and IV) that are a part of the permit are not
included in this draft document but can be viewed online or downloaded for inspection at
https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
At this time,we are also giving public notice of draft permits NC0020081and NC0021156 for the
City of Belmont and City of Mount Holly,respectively.This is necessary in light of the transfers
of nutrient allocations anticipated among the three facilities.
The authorization to discharge from the new Joe Stowe,Jr. RWWTP to surface waters is
conditioned on acquiring nutrient allocations through connection of the Mount Holly and/or
Belmont wastewater systems to the new facility and rescission of those municipalities' NPDES
permits.
The nutrient allocations tables and effluent limits in Part I are intended to allow for the transfer
of allocations from Mount Holly and/or Belmont to the new plant and the equivalent changes
in nitrogen and phosphorus limits without requiring additional permit modifications. If the
circumstances of a transfer differ from those anticipated in the permit,a modification will be
required to address those circumstances.
If you have any questions concerning the draft permit, please contact me at [phone] or at
[e-mail].
Sincerely,
Michael E.Templeton,P.E.

A.(5.) MERCURY MINIMIZATION PLAN
[G.S. 143-215.1(b)]
The permittee shall develop and implement a mercury minimization plan during this permit term. The
MMP shall be developed within 180 days of the NPDES Permit Effective Date 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://portal.ncdenr.org/web/wq/swp/ps/npdes,under
Model Mercury Minimization Plan). The MMP should place emphasis on identification of mercury
contributors and goals for reduction. Results shall be summarized 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.(6.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT
[15A NCAC 02B .0500 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodaphnia dubia at an effluent concentration of 19.7% (15 MGD) or 29.0% (25.0 MGD).
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 II 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 duringa month in which toxicitymonitoringis required,monitoring
q
will be required during the following month. Assessment of toxicity compliance is based on the toxicity
Part I,Page 5 of 13

DRAFT Permit NC0089630
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.
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.(11.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 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.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements[Supersedes Part II,Section D. (2.) and Section E. (5.)(a)1
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.
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.
A.(11.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS (cont.)
Part I,Page 11 of 13

D RAFT Permit NC0089630
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.
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-reporting-rule
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 time,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: http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements[Supplements Part II,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.(11.)(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:
