Re: Application for Permit Renewal
Aqua North Carolina, Inc.
Highway 150 WWTP (River Park)
NPDES No. NCO074900
Iredell County
Good Afternoon:
Enclosed are three (3) copies of the completed application Form D-WWTP. This
submittal includes the necessary attachments for your office to renew the subject
permit.
Aqua North Carolina is requesting the three per week summer Fecal Coliform frequency
requirement be updated to reflect standard monitoring requirements for a facility of this
size. The Hwy 150 WWTP has not demonstrated a history of elevated fecal results to
necessitate the additional monitoring requirement.
Should you need any additional information or assistance, please feel free to contact
me (919) 653-6965 or by e-mail at AAOwens@aquaamerica.com.
Sincerely,
Amanda Berger
Director, Environmental Compliance

Subject: Issuance of NPDES Permit NCO074900
Aqua North Carolina, Inc. — Highway 150 WWTP
Iredell County
Dear Mr. Melton:
PAT MCCRORY
Governor
DONALD R. VAN DER VAART
Secretary
S. !AY ZIMMERMAN
Director
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge 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).
This final permit contains the following changes to its terms from those found in the draft permit sent
to you on April 20, 2016:
On the limits and monitoring requirements pages of the permit, the word "non -industrial" has been
added as a parenthetical elaboration of the type of wastewater that may be treated at the facility,
because the WWTP treats wastewater from commercial sources in addition to private residences.
• Section A. (3.) [Special Condition — Flow Expansion Request] in the draft permit has been
removed from the final version of the permit, and the remaining conditions have been renumbered.
You are also reminded of the new condition requiring electronic reporting of discharge monitoring
report (DMR) data using the Division's eDMR internet application. This new requirement will
become effective on December 21, 2016.
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.

(a) Contacting Public Health Directors
The facility must notify the Iredell, Lincoln, Catawba, and Mecklenburg County Public Health Directors within
12 hours of first knowledge by the owner/operator of any discharge of untreated wastewater to waters of the
State or a discharge from the wastewater treatment plant that has not received adequate disinfection due to a
malfunctioning treatment unit.
The County Public Health Directors can be contacted using the following information:
Current County Health Director Information as of April 2016
Catawba County Health Director
3070 1 lth Ave. Dr. S.E.
Hickory, NC 28602

704-878-5300
Mecklenburg County Health Director
249 Billingsley Road
Charlotte, NC 28211
704-336-4700
The facility must notify the public of untreated wastewater spills. Wastewater facility owners or operators must
issue a press release after a discharge to surface waters of 1,000 gallons within 48 hours of first knowledge of
the spill by the owner/operator. The press release must be issued to "all electronic and print news media outlets
that provide general coverage in the counties (Iredell, Lincoln, Catawba, and Mecklenburg) where the discharge
occurred." A copy of the press release must be maintained for one year by the owner/operator. This press
release is required in addition to the permit requirement of contacting the North Carolina Division of Water
Resources (DWR).
If a discharge of 15,000 gallons or more reaches surface water, a public notice is required in addition to the press
release. The public notice must be placed in a newspaper having general circulation in the County in which the
discharge occurred and the county immediately downstream. At a minimum the notice should be published in
the newspaper of general circulation in Iredell, Lincoln, Catawba, and Mecklenburg Counties. If a discharge of
1,000,000 gallons of wastewater or more reaches surface waters, the DWR regional office must be contacted to
determine in what additional counties, if any, a public notice must be published. A copy of these public notices
and proof of publication must be sent to the DWR within 30 days of publication. The copy should be sent to the
following address:
PERCS Unit
Division of Water Resources
1617 Mail Service Center
Raleigh, NC 27699
The minimum content of the notice is the location of the discharge, estimated volume, water body affected and
steps taken to prevent future discharges.

Permit NCO074900
A. (4.) 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 and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit monitoring data and reports electronically to the Environmental Protection Agency
(EPA). 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 1 Supersedes Section D. (2.) and Section E. (5.) (a)_l
Effective December 21, 2016, the permittee shall begin reporting 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 DENR / 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.
Page 6 of 9
Permit NCO074900
A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS, continued
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver
from Electronic Reporting" section below).
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.oEg/web/wq/admin/bo iyu/edmr
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.
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: htt://www2.e a. ov/com liance/final-national- ollutant-dischar e-elimination-system-n des -
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:
