Dear Ms. Smith:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject
facility. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1
and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007, or as subsequently amended.
The Division understands that you have made no significant changes to your facility since the last permit
renewal. We have made the following updates to your previous permit in the August 10, 2016 and October 5,
2016 drafts:
1. updated facility description on supplement to permit cover sheet
2. added updates to facility map including adjustment of Outfall 002 coordinates to
36.071979, -79.918421
3. updated receiving stream as Long Branch for Outfall 002 as indicated in GIS mapping instead of
it being an unnamed tributary (UT) to long branch
4. added flow rational equation [see Footnote 2 and Special Condition A. (2.)]
5. added monthly average limit of 30 mg/L for Total Suspended Solids (TSS)
6. changed annual toxicity monitoring to Acute Whole Effluent Toxicity (WET) testing [TGE6G] at
90%; 24 hour static and updated Footnote 6 [Condition A. (3.)]
7. added monthly effluent Turbidity monitoring including 50 NTU effluent limits (both daily
maximum & monthly average) along with Footnote 3 regarding receiving stream turbidity [15A
NCAC 02B .0211 (21)]
8. added electronic reporting of discharge monitoring reports (eDMR) in Section A. (4.).
Changes made since the October 5, 2016 draft permit include the following:
9. added Footnote 4 regarding sampling for O&G as in the previous permit; however, the O&G
parameter code [00556] remains the same for submitting DMR/eDMR, but uses test EPA method
1664 (SGT-HEM) with results in mg/L
10. removed footnote regarding samples being collected concurrently with annual Acute Toxicity

11. added Footnote 5 which requires that all practical quantitation limits (PQL) must be sufficiently
sensitive considering the respective water quality standard for each parameter [see Part II. Section
D. (4.)].
Starting December 21, 2016, federal regulations require electronic submittal of all discharge monitoring
reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The final
NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your final
NPDES permit. [See Special Condition A. (6.)] For information on eDMR, registering for eDMR and
obtaining an eDMR user account, please visit the following web page:

Footnotes:
1. Starting on December 21, 2016, begin submitting Discharge Monitoring Reports electronically using NC
DWR's eDMR application system. See Condition A. (4.).
2. Each discharge event shall be monitored for Flow volume and duration — During periods of no flow, the
Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR) indicating "No discharge."
Flow may be documented using any one of the following four (4) methods:
1) measure flow continuously via weir or flow meter (totalizer preferred);
2) estimate flow at 20-minute intervals during the entire discharge event;
3) report flow based on discharge pump logs; or
4) calculate flow based on total rainfall per unit area draining to the outfall using the
Rational Method [see formula, Section A. (2.)].
3. Turbidity — Effluent turbidity shall not cause receiving -stream turbidity to exceed 50 NTU. If background
turbidity naturally exceeds 50 NTU, the effluent shall not cause background turbidity to increase. Any
discharge exceeding this permit limit will require sufficient instream sampling (upstream and/or downstream)
to verify compliance (effluent vs. background). [NCAC 02B. 0211(21)]
Page 3 of 8

NPDES Permit NC0074578
4. Where possible, the grab sample for Oil & Grease should be skimmed from the water surface of a
quiescent (calm water) zone.
5. All practical quantitation limits (PQL) must be sufficiently sensitive considering the respective water quality
standard for each parameter [see Part II. Section D. (4.)].
6. If Acute WET -test fails [TGE6C], the Permittee shall test each subsequent discharge event until testing
indicates "pass," after which Quarterly monitoring shall resume in accord with Section A. (3.). If after a
subsequent five (5) consecutive Quarterly events, WET results demonstrate no toxicity (i.e., "pass"), the
Permittee may petition the Division to relax monitoring, as data may warrant. WET -test samples shall be
collected concurrently with other POC samples, as appropriate to monitoring frequencies.
Conditions:
• The Permittee shall discharge no floating solids or foam.
• Direct discharge of tank solids, tank -bottom water, or the rag layer is not permitted.
• Hydrostatic Tank Testing: The Permittee shall discharge no tank solids, no tank bottom -water, no tank
rag -layer; no tank [or pipe] contents, unless Benzene concentration tests less than 1.19 µg/L and
Toluene concentration tests less than 11 µg/L.
A. (2.) FLOW MEASUREMENT RATIONAL [G.S. 143-215.1(b)]
The Rational Method - Determination of Peak Runoff:
[REF: FHWA Urban Drainage Design Manual, 3.2.2. Rational Method (3-1)]
Q=KuCIA, where:
Q = flow (peak flow rate in cfs or m3/sec)
Ku = unit conversation factor = 1.008 for U.S. standard units (usually
ignored because it is so close to 1), or 0.278 for metric units
C = dimensionless runoff coefficient for the watershed, loosely defined as the
ratio of runoff to rainfall
I = intensity of rainfall [taken from the intensity -duration -frequency curves
for the specified design return period at the time of concentration, tc
(in/h or mm/h). tc = time of concentration (time after beginning rainfall
excess when all portions of the drainage basin are contributing
simultaneously to outlet flow).
A = area of tributary watershed (acres or km2)
The rational equation is used to calculate the runoff from a region, given:
• the runoff coefficient (accounts for infiltration losses in the region),
• the rainfall intensity to the region,
• the time for runoff to travel from the region's upper reaches to its outlet, and
• the region's drainage area.

NPDES Permit NC0074578
A. (3.) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A
Single Effluent Concentration" (Revised December 2010 or subsequent versions). The monitoring shall
be performed as a Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent
concentration at which there may be at no time significant acute mortality is 90% (defined as treatment
two in the procedure document). The tests will be performed during the months of January, April,
July and October. 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.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGE6C. Additionally, DWR Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
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 and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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, then
monthly monitoring will begin immediately until such time that a single test is passed. Upon passing,
this monthly test requirement will revert to quarterly in the months specified above. 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 third month.
Page 5 of 8

NPDES Permit NC0074578
Should any test data from either these monitoring requirements 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 monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival 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.) 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 and specify that, if a state does not establish a system to receive such submittals, then permittees
must submit monitoring data and reports electronically to the Environmental Protection Agency (EPA).
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.)

Effective December 21, 2016, 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. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:

NPDES Permit NC0074578
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 mailing
address above. 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)].
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: http://www2.epa.gov/compliance/final-national-pollutant-
discharge-elimination-system-npdes-electronic-reporttint;-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
Page 7 of 8

NPDES Permit NC0074578
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
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d).1
