Subject: Draft NPDES Permit NC0023337
Scotland Neck WWTP
Grade II I Biological WPCS
Halifax County

Dear Ms. Dempsey:

Th e 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 contain s.

The draft permit includes the following significant changes from the existing permit:
1. The facility classification Grade III Biological Water Pollution Control System (WPCS) was added
to the effluent page.
2. The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water
Resources is required to implement the new dissolved metal standards in all permits public noticed
after April 6, 2016.
The new standards for most metals include acute standards. Furthermore, the freshwater
stand ards for several metals are expressed as the dissolved form of the metals, and seven metals
have hardness-dependent equations. As a result, the Division will need site-specific effluent
hardness data in order to calculate permit limitations. Instream data will not be necessary
because of the zero flow conditions (7Q10/30Q2 = 0) of the discharge. The metal of concern for
this permit renewal is Copper.
To evaluate dissolved Copper, a Reasonable Potential Analysis (RPA) was conducted using data
from the DMRs submitted from May 2016 to August 2020. Results indicated a reasonable
potential to exceed the new dissolved metals standard for Copper. Consequently, the following
daily maximum limits (acute standard) and monthly average limit (chronic standard) for Total
Copper will be applied for this permit renewal:
Parameter Outfall Monthly Average

Daily Maximum
Total Copper 001 10.56 µg/L 14.46 µg/L
Additional information for effluent hardness received October 14, 2020 was entered into the
RPA to calculate the above limits. Since this facility discharges under zero 7Q10 flow
conditions, a value of 0 was entered for all stream flow data for Outfall 001. Please note that
under zero flow conditions a default value of 25 mg/L will be used for the upstream Total
Hardness. The flow limit of 0.675 MGD for Outfall 001 was used as the effluent flow. For a
summary of this information, please see the attached “Dissolved to Total Metal Calculator”.
3. A compliance schedule for the new limits has b een added as permit Condition A. (2.). Compliance with
these limits shall commence on October 31, 2024, on the permit expiration date.
4. The chronic toxicity monitoring special condition A. (3.) was updated.
5. The electronic reporting permit special condition A. (7.) was updated.
6. The permit map was updated.

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 Halifax 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. If you have questions concerning the draft, please
contact me at 919-707-3618, or via e-mail at [e-mail].

A. (3.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B .0200]

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
“North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,” (Revised December 2010, or subsequent
versions) or “North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure” (Revised December
2010, or subsequent versions). The tests will be performed during the months of February, May, August, and November. These months signify the first month of each three-month toxicity testing quarter assigned to the
facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in “North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure” (Revised-December 2010, or subsequent versions).

All toxicity testing results required as part of this permit condition will be entered electronically using the
Division’s eDMR system for the months in which tests were performed, using the parameter code TGP3B for
the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent to
the following address:
North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 27699-1621
Or, results can be sent to the email, [e-mail]. Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days
after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of “No Flow” in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter,
which is the three-month time interval that begins on the first day of the month in which toxicity testing is
required by this permit and continues until the final day of the th ird month.

Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Resources indicate potential impacts to the receiving stream, this permit may be re-opened and modified
to include alternate monito ring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

A.(4.) CALCULATION OF TOTAL NITROGEN AND TOTAL PHOSPHORUS LOADS
[G.S. 143-215.1(b)]
(a.) The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN (or TP) Load (lb/mo) = TN (or TP) x TMF x 8.34 where:

TN or TP = the average Total Nitrogen or Total Phosphorus concentration (mg/L) of the
composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TN (or TP) Load (lb/yr) = Sum of the 12 Monthly TN (or TP) Loads for the calendar
year
(b.) The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L and lb/mo)
in the appropriate discharge monitoring report for each month and shall report each calendar
year's results (lb/yr) with the December report for that year.
A.(5.) ANNUAL LIMITS FOR TOTAL NITROGEN OR TOTAL PHOSPHORUS
[G.S. 143-215.1(b)] (a.) Total Nitrogen (TN) and Total Phosphorus (TP) allocations and load limits for NPDES
dischargers in the Tar-Pamlico River basin are annual limits and apply on a calendar year basis.
(b.) For any given calendar year, the Permittee shall be in compliance with the annual TN (or TP)
Load limit in this Permit if:
(i.) the Permittee's annual TN (or TP) Load is less than or equal to the effective limit, or
(ii.) the Permittee is a Co -Permittee Member of a compliance association.
(c.) If the Permittee is not a co -permittee member of a compliance association and the Permittee’s cumulative annual TN (or TP) discharge exceeds the effective TN (or TP) Load limit in this
permit at any point during the calendar year, the Permittee is in violation of its TN (or TP) Load limit for the remainder of the calendar year, and each day of continuing violation shall constitute a separate violation. Compliance with annual limits shall be determined separately for each calendar year, and an exceedance in one year does not carry forward to subsequent years.
(d.) The TN (or TP) Load limit in this Permit (if any) may be modified as the result of allowable
changes in the Permittee's allocations.
(i.) Allowable changes include those resulting from purchase of TN (or TP) allocation from an
authorized mitigation banker, the Ecosystem Enhancement Program, or other source allowed
under applicable regulations; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; and other transactions approved by the Division and
consistent with the Tar-Pamlico River Basin Association Agreement, as revised.
(ii.) The Permittee may request a modification of the TN (or TP) Load limit in this Permit to reflect allowable changes in its allocation(s). Upon receipt of timely and proper application,
the Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
(iii.) Changes in TN (or TP) limits become effective on January 1 of the year following permit modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
(iv.) Application shall be sent to:

(e.) If the Permittee is a member and co-permittee of an approved compliance association on January 1 of a given year, its TN and TP discharges during that year are governed by that association's group NPDES permit and the limits therein.
(i.) The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
(ii.) Association roster(s) and members' TN and TP allocations will be updated annually and in
accordance with state and federal program requirements.
(iii.) If the Permittee intends to join or leave a compliance association, the Division must be notified of the proposed action in accordance with the procedures defined in the association's
NPDES permit.
(A) Upon receipt of timely and proper notification, the Division will modify the permit as appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.
(f.) The TN and TP monitoring and reporting requirements in this Permit remain in effect throughout the term of the Permit and are not affected by the Permittee's membersh ip in a compliance
association.
A.(6.) NUTRIENT ALLOCATIONS [G.S. 143-215.1(b)]
(a.) Total Nitrogen (TN) and Total Phosphorus (TP) allocations represent the maximum TN and TP
loads that a discharger or group of dischargers is potentially allowed under the Tar-Pamlico
nutrient management strategy. Allocations are not enforceable limits but are the basis for TN and TP limits established in individual or group NPDES permits.
(b.) The allocations originally assigned to the Tar-Pamlico Basin Association members total 889,274
lb/yr (404,274 kg/yr) TN and 160,372 lb/yr (73,060 kg/yr) TP. These group allocations have been divided among the members in proportion to the maximum permitted flow in each member’s permit; that is,

For the purposes of this distribution, individual permitted flows for the Association members are
those in effect as of July 2014 and result in a Total Permitted Flow of 62.495 MGD.
(c.) The following table lists, for information purposes only, the TN and TP allocations assigned to, acquired by, or transferred to the Permittee in accordance with the Tar-Pamlico River Basin Phase IV Agreement. Applicable TN or TP limits are established in the Effluent Limitations conditions
of this permit or in the NPDES permit of a compliance association of which the Permittee is a Co -Permittee Member.

Any addition, deletion, or modification of the listed allocation(s) (other than to correct typographical errors) or any change from Reserve to Active 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. (7.) ELECTRONIC REPORTING OF 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)]
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:

NPDES Permit NC0023337
Page 9 of 10

• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.

NPDES Electronic Reporting Rule – Phase 2 Extension. EPA is proposing to extend the Phase 2 deadline from December 21, 2020 until at least December 21, 2023. The current compliance date will be extended if the implementation date is extended as a final regulation
change in the federal register.
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(l)(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

3. How to Request a Wa iver 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 durat ion 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 report ing 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.
