Subject: Draft NPDES Permit NC0030783
Baton Elementary School WWTP
Grade I Biological WPCS
Caldwell County
Dear Dr.Church:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review
this draft carefully to ensure thorough understanding of the requirements and conditions it contains.
There are several changes in the draft from the existing permit. These changes are summarized below.
• Regulatory Citations—Language has been added throughout the permit to provide regulatory
citations for permit requirements.
• Electronic Reporting—Permit language has been updated to be consistent with the fmalization of
federal requirements for electronic reporting.
• Parameter Codes—Codes have been updated as necessary in the table in Section A. (1).
• Ammonia Nitrogen(NH3-N)Monitoring—In the current permit you monitor 2 times per month
for NH3-N and have a summer effluent limit of 3 mg/L(monthly average)and 15 mg/L(weekly
average)and winter limits of 11 and 35 mg/L. Recent review by Division staff has noted that
15A NCAC 2B .0404(c)requires that winter waste load allocations for oxygen consuming waste
be no less stringent than 2 times the summer waste load limit. To meet this rule requirement
winter limits for NH3-N are being adjusted in your permit.
The draft permit includes proposed changes to the winter limits that will reduce the monthly
average limit to 6 mg/L and the daily max to 30 mg/L. A review of your monitoring data over the
permit cycle indicates that no winter NH3-N value has exceeded 6.5 mg/L,so the individual
values are well below the proposed daily max. In addition,no monthly values were above the
proposed limit. For all values reported during the winter period,half of the values were actually
below the 0.2 detection limit. Based on the data reviewed from the previous permit cycle it
appears that the proposed change in the winter limits will be well within the values that this
treatment system routinely attains.

NOTE: This special condition supplements or supersedes the following sections within Part II of this

• Section B. (11.) Signatory Requirements
• Section D.(2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
Page 3 of 7
Draft Permit NC0030783
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)I
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
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)].
Page 4 of 7
Draft Permit NC0030783
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/2015/10/22/201 5-24954/national-pollutant-di scharge-
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.ne.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.)(b)and Supersedes Section B.(11.)(d)l
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:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel

persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility of fines and imprisonment for knowing violations."
