Subject: Draft NPDES Permit Modification
Permit NCO030716
Central Johnston County Regional WWTP &
210 WWTF
Johnston County
Grade IV Biological WPCS
SIC Code 4952
Dear Ms. Farmer:
The Division of Water Resources staff has reviewed your September 29, 2023 request for modification of
the Central Johnston County Regional WWTP and 210 WWTF's NPDES permit to revise the County's
permitted capacities at each facility based on need for expansion of the 210 WWTF. This modification also
includes incorporation of revision of the combined total nitrogen allocation to reflect the County's pending
purchase of nitrogen offset credits. 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 from the existing permit, including the following:
• The offset credits purchased by the County have been added to the table of allocations. The offset
credits will be held in reserve until they become available upon future expansion of the facility [See
A.(14).].
• A new footnote to the table documents the total amount of offset credits to be purchased and the
amount available to the Town for its NPDES discharge [See A.(14).].
• References to " allocation"have been revised to include offset credits [See A.(14).].
• The Total Nitrogen Delivered Load combined limitations outlined in Special Condition A.(7.)
have been revised to reflect the offset credits.
• Effluent Limitations and Monitoring Requirements tables for the Central Johnston County
Regional WWTP have been revised to reflect the requested 9.5 MGD, 8.0 MGD and 6.0 MGD flow
tiers [See A.(L),A.(2.), and A.(3.)].
• Effluent Limitations and Monitoring Requirements tables for the 210 WWTF have been revised
to reflect the requested 4.0 MGD, 8.0 MGD and 12.0 MGD flow tiers [See A.(4.),A.(5.), and A.(6.)].
To track expanded effluent impact on the receiving stream,instream requirements have been
revised.
• To assess PFAS assess levels in the facility effluent to a WS-V waterbody, Special Condition
A.(17.)has been added to the permit.
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.

A.(17.) PFAS MONITORING REQUIREMENT AND PRETREATMENT
[G.S. 143-215.1 (b)]
(a.) In the absence of an approved 40 CFR Part 136 method published in Federal Register, influent and
effluent PFAS monitoring shall be conducted. The 3rd draft or more recent wastewater analytical
method 1633 (see 40 CFR 122.21(e)(3)(ii) and 40 CFR 122.44(i)(1)(iv)(B)) shall be used and shall
include all target analytes listed under Table 1 of the method until such time as the Permittee uses the
approved PFAS Method for wastewater. Effective the first full calendar quarter following six (6)
months after EPA publishes a 40 CFR Part 136 PFAS Method for wastewater in the Federal Register,
effluent PFAS monitoring shall be conducted using the approved EPA PFAS Method 1633. See
Appendix A for list of analytes.
(b.)Influent and effluent monitoring using the draft analytical method takes effect the first full
calendar quarter following six(6) months after the effective date of the permit (Month xx, 2024)
and will be at a quarterly frequency thereafter.
Appendix A has been added to the permit to identify the current analytes listed under Table 1 of
Method 1633 Analysis of Per- and Polyfluoroalkyl Substances(PFAS) in Aqueous, Solid,
Biosolids, and Tissue Samples by LC-MS/MS (EPA,January 2024) and the appropriate ICIS codes
for use when reporting in the electronic Discharge Monitoring Reports(eDMRs). The method and
list of analytes may also be found at:
https://www.epa.gov/system/files/documents/2024-01/method-1633-final-for-web-posting.pdf
PFAS Monitoring using the Draft Method or January 2024 Method 1633 shall be reported quarterly
using the Division-provided submittal form. Once PFAS monitoring is conducted using the EPA
Method 1633 in 40 CFR Part 136, data shall be reported in the monthly eDMRs.
Please note that specific considerations and protocols are required to avoid cross-contamination and
minimize sample bias for PFAS. A current listing of laboratories accredited by the Perry Johnson
Laboratory Accreditation, Inc. (PJLA), ANSI National Accreditation Board (ANAB), or the
American Association for Laboratory Accreditation (A2LA) to perform EPA Method 1633 can be

A.(18.) 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 monthly 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:Hdeq.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.
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; and
• Pretreatment Program Annual Reports; and
• Clean Water Act(CWA) Section 316(b)Annual Reports.

Permit NC0030716
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-pollutant-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
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
