Subject: Draft NPDES Permit NC0046043
Oak Ridge Military Academy WWTP
Grade II Biological WPCS
Guilford County
Dear Mr. Shreve:
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure a
thorough understanding of the information,conditions,and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
1. The facility classification Grade I Physical Chemical Water Pollution Control System(WPCS)was added to
the effluent page.
2. The electronic reporting permit special condition A. (3.)was updated.
3. The permit map was updated.
Please note that Haw River is listed as an impaired waterbody on the North Carolina 303(d)Impaired Waters List.
Addressing impaired waters is a high priority with the Division,and instream data will continue to be evaluated.
If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility,
then mitigative measures may be required.
The NPDES standard conditions(Parts II, III,and IV)that are a part of the permit are not included in this draft
document(cover,map,and Part I).The conditions are the same as in your current permit except that agency and
division names have been updated.The latest version is available at https://bit.ly/2BZ4xxx and can be viewed
online or downloaded as a PDF file.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Guilford County area,per EPA requirements. Please provide your
comments,if any,to me at the address below no later than 30 days after receiving this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit.

A. (2.) NUTRIENT REOPENER CONDITION
[NCGS 143-215.1 (b)]
Pursuant to N.C.General Statutes Section 143-215.1 and the implementing rules found in the North Carolina
Administrative Code at 15A NCAC 2H.0112(b)(1)and 2H.0114(a)and Part II sections B-12 and B-13 of this
permit,the Director may reopen this permit to require supplemental nutrient monitoring of the discharge. The
purpose of the additional monitoring will be to support water quality modeling efforts within the Cape Fear River
Basin and shall be consistent with a monitoring plan developed jointly by the Division and affected stakeholders.
In addition,the results of water quality modeling may require that limits for total nitrogen and total phosphorus be
imposed in this permit upon renewal.
A. (3.) ELECTRONIC REPORTING - 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 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. The eDMR system may be
accessed at: https://deq.nc.gov/about/divisions/water-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

NPDES Permit NC0046043
See"How to Request a Waiver from Electronic Reporting"section below.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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, 2025, 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-pol lutant-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
Page 5 of 6

NPDES Permit NC0046043
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 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
