Subject: Draft NPDES Permit NC0074837
Bridgeton WWTP
Grade WW-2 WPCS
Craven County
Dear Permittee:
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 your thorough
understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
➢ A reopener condition for all Neuse river discharge permits has been added at Part I. (A.) 7.
➢ Electronic data submission requirements have been updated.
The Neuse River segment where your facility discharges is listed as an impaired stream on North
Carolina's 303 (d) list. Currently,the stream does not meet all water quality standards. If the
limitations.in the current permits for facilities discharging to the Neuse River do not result in improved
wafer quality,removal of discharges may be necessary for the health of the stream:
We will continue to monitor compliance at your facility. If noncompliance with your permit's effluent
limits is shown to be a direct cause of stream degradation,the Division will recommend removal of your
facility's discharge.
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/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 Craven County area, per EPA requirements.

Any addition, deletion, or modification of the listed allocation(s) (other than to correct typographical
errors) or any change in status of any of the listed allocations shall be considered a major modification
of this permit and shall be subject to the public review process afforded such modifications under state
and federal rules.
A. (5) TEMPORARY MEANS OF DISINFECTION
[NCGS 143-215.1 (a)]
In the event that the wastewater treatment plant's ultraviolet(UV) disinfection system should fail,
under-perform, or otherwise be removed from effective service,the permittee or his agent should
immediately inform the Washington Regional Office and discuss temporary, alternate means for
disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection,the Total Residual Chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method of disinfection is in
use and values must be reported on the discharge monitoring report. TRC in the effluent may not exceed
28 µg/L; therefore, dechlorination methods may also be necessary to ensure protection of water quality
in the receiving stream. = _:
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 record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 µg/L.
Use of a disinfection system other than the permitted UV system duringcircumstances not deemed
Y as
emergency and/or temporary (replacement of lamps, lamp cleaning or maintenance, etc.) will be
considered a violation of the terms of this permit.
A. (6) EFFLUENT MERCURY ANALYSIS
[NCGS 143-215.66]
The Permittee shall provide one effluent mercury analysis, using EPA Method 1631E, in conjunction
with the next permit renewal application. The analysis should be taken within 12 months prior to the
Page 6 of 9

Permit NC0074837
application date. Any additional effluent mercury measurements conducted from the effective date of
this permit and up to the application date shall also be submitted with the renewal application.
If the result of the mercury analysis is not provided with the application,the application may be returned
as incomplete and the Permittee considered non-compliant.
A. (7) PERMIT RE-OPENER: NUTRIENT MANAGEMENT
[NCGS 143-215.1 (b)]
a) Pursuant to N.C. General Statues Section 143-215.1 and implementing rules found in Title 15A of North
Carolina Administrative Code, Subchapter 02H, specifically, 15A NCAC 02H.0112(b)(1)and 02H.0114(a),
and Part II, Sections B.12 and B.13.of this Permit,the Director of DWR may reopen this permit to require
nutrient management measures for the discharge. The results of water quality monitoring,modelling or other
evaluations may require that conditions for total nitrogen and total phosphorus control be imposed on this
permit.
b) The Division may,upon written notification to the permittee,re-open this permit in order to incorporate or
modify effluent limits,monitoring and reporting requirements,and other permit conditions when it deems
such action is necessary to implement TMDL(s)approved by the USEPA.
A. (8) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 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.)(all
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
