Subject:
Draft NPDES Permit NCO020095
St. Pauls WWTP
Grade II Biological WPCS
Robeson County
The Division has reviewed your request to renew the subject permit. Enclosed with this letter is a copy
of the draft permit for your facility. 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:
➢ Updated eDMR parameter codes for Temperature and Total Nitrogen in the effluent table in
Section A. (1.).
➢ Added parameter units to the effluent table in Part I. Section A. (1.).
➢ Updated the effluent limit for Total Mercury in the table in Section A. (1) to 36 ng/L. with
quarterly monitoring based on the Mercury WQBEL evaluation using the last 4.5 years of
mercury sampling data and the 2015 Memo describing Mercury TMDL Implementation.
➢ Reporting for Total Nitrogen (TN) now includes the constituent parameters used in calculating
TN. Total Kjeldahl Nitrogen (TKN) and Nitrate + Nitrite Nitrogen (NO3-N + NO2-N) have
been added to the effluent table in Section A. (1) with a corresponding footnote. The Sample
Type for Total Nitrogen has been updated from "Composite" to "Calculated".
➢ Updated Part I. Section A. (2) to reflect current federal requirements for Electronic Reporting
of Discharge Monitoring Reports.
➢ Updated the map.
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 1). 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/3k5NFaL 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 Robeson 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. Your written comments are welcome, but they are not mandatory.

Downstream = at least 300 feet downstream from the outfall.
3. The monthly average BOD-5 and Total Suspended Solids (TSS) concentrations shall not exceed 15% of
the respective influent value (i.e., 85% removal is required).
4. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with
the permit. However, the Permittee shall continue to report all values detected by North Carolina -
certified laboratory test methods (including field certified), even if these values fall below 50 µg/L.
5. For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen, and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively.
All samples collected should be from a representative discharge event.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN

A. (2.) 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.)
• Section D. (6.)
• Section E. (5.)

Monitoring Reports
1. Reoortine Requirements ISuaersedes 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:Hdeg.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

NPDES Permit NC0020095
Raleigh, North Carolina 27699-1617
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:
httr)s://www.federalreeister. eov/documents/2015/ 10/22/2015-24954/national-pollutant-dischar¢e-
elimination-system-npdes-electronic-reWrtin -rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reportine
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
Page 5 of 6

NPDES Permit NCO020095
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:
ho://deg.nc.gov/about/divisions/water-resources/edmr
4. Sianatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
