Subject: Issuance of NPDES Permit Modification
NPDES permit NCO063860
Harbor Estates WWTP (WW-2)
Mecklenburg County
Dear Mr. Becker:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject
facility. 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.
On November 20, 2017, Aqua North Carolina, Inc. requested that a schedule of compliance be inserted into
the permit to allow time to achieve compliance with new limits for Total Copper and Total Chlorine. The
W WTP plant was not meeting limits for Copper and Chlorine with 100% domestic wastewater with no
addition of filter backwash wastewater form the potable water systems. The filter backwash sources were
added in the previous permit modification issued April 24, 2017. The permittee proposes to investigate
possible treatment options, modeling for the lake with the addition of a diffuser, and to gather more data for
these parameters for future analysis of limits. The schedule of compliance found in Part I, Section A. (2.)
modifies both effluent tables in Part 1, Sections A. (L) and A. (3.) as indicated with Footnote 8 (see draft
permit).
Please note the following changes made since the draft modification:
1. Comments on the draft by the permittee requested that additional parameters that were limited in the
previous modification be added to the compliance schedule included in this modification. No data
was submitted to support this request to expand the compliance schedule for other parameters. Such
additional modification may also require further submittal for public notice. Therefore, the Division
has determined that this modification will only include a compliance schedule for Copper and
Chloride limits as originally requested.
2. The permittee requested that the achievement date for compliance with Copper and Chloride limits be
extended to 48 months from the effective date of the modification. Federal guidelines require that
NPDES permit cycle be no greater than 5 years. Therefore, the achievement date for the compliance

schedule will coincide with the expiration of the current permit on June 30, 2020. The compliance
schedule has been modified to only include three (3) schedule items as listed. See Section Part I A. (2.).
3. A technical correction to Strontium-90 has been made to indicate the correct standard of 8 pCi/L
(an annual average) as the permit limit. The narrative standards for radioactive substances are found
at 15A NCAC 02B .0211 (17) and 40 CFR 141.26 (adopted by reference).
If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable,
you have the right to an adjudicatory hearing, upon written request submitted within thirty (30) days after
receiving this letter. Your request must take the form of a written petition conforming to Chapter 150B of
North Carolina General Statutes, and you must file it with the Office of Administrative Hearings, 6714 Mail
Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall remain
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. If you have questions, or if we can be of further service,
please contact Derek Denard at [[e-mail]] or call [phone].

versions.
The effluent concentration defused as.treatment two in the procedure document is 90%. The testing shall be
performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the months of
January, April, July and October. 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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
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, 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 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 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, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
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. (8.) 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.)
• Section D. (6.)
• Section E. (5.)
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes 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.
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: htti)://www2.gpa.goy/compliance/final-national-pollutant-
dischgge-elimination-s sy tern-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:

Derek,
I apologize for the delayed comment. I know we are outside of the 30 day response time but
Amanda Owens who just joined Aqua as our new Regional Compliance Manger was reviewing
the Draft Permit modification and raised some concerns that I did not capture. We discussed
the following issues that need to be incorporated into the permit.
First is what appears to be a typographical error in the limits for Chronic WET testing. The
original Modified Permit dated April 24, 2017 and the Technical Correction issued November
2, 2017 had the limit on this Parameter blank with a reference to Footnote 12. The draft
permit issued December 13, 2017 has "Monitor & Report". Since Chronic Toxicity is identified
in Footnote 12 as pass/fail at 90%, we believe the Monitor & Report in the limit is incorrect.
Secondly, the draft permit only calls out Total Copper and Total Chlorine identified under the
proposed monitoring period. It is our request that all of the new limits imposed at the time
the Modified Permit was issued would be covered under the requested compliance
period. We feel that it is in everyone's best interest to correct these items in the existing
modification request rather than to prolong the process with another modification request.
Thank you for your consideration.
Best regards,
Laurie Ison

Section A.(1.) Effluent Limitations and Monitoring Requirements
Footnote 8 — We would like a period of forty-eight months from the effective date of the revised

5. We would like a period of four years to achieve compliance with Total Copper and Total
Chloride limits specified in Section A.(1.) and A.(3.). Note that the reference to A.(5.) in the
draft permit appears to be incorrect and should read A.(3.).

Dear Mr. Hennessey:
Application for Permit Modification
Aqua North Carolina, Inc.
Harbor Estates WWTP
NPDES No. NCOO6386O
Mecklenburg County
This letter and attached processing fee are being submitted with our request to modify the subject
permit to allow for a compliance period to meet the new limits which were added in the recent
modification allowing for the introduction of backwash from Aqua's potable water systems.
This request would allow Aqua to investigate possible treatment, modeling, testing and possibly
adjusting permit limits for Total Chloride and Total Copper to account for the domestic
discharge currently being discharged into the WWTP.
During the investigation and subsequent modification to the permit it has become evident that the
domestic wastewater currently being treated at the WWTP exceed the minimum level of Total
Chloride and Total Copper as no backwash has yet to be introduced into the facility under the
new permit.
We appreciate your consideration of this request for modification. If you need any additional
information or assistance, please feel free to contact Laurie Ison at 704-489-9404.
