Subject: Draft NPDES Permit NC0089087
EAE - Wilson
Wilson County
Dear Mr. Golson:
In response to your request to renew the subject NPDES permit, the Division of Water Resources
(DWR or the Division) hereby transmits this draft for your review and comment. Please review this
document to assure your understanding of the permit limits and monitoring conditions, and to correct
errors, if any.
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:
1. The facility map has been updated.
2. Acute Whole Effluent Toxicity(WET)has been changed to quarterly. Administrative code
(15A NCAC 02B .0508) states WET testing is to be performed quarterly. WET testing
reductions is a programmatic change that the Division will continue to evaluate. However,
given the concern to protect the state waters from toxic substances, emerging contaminants,
and the cost effectiveness of the single test concentration procedure the Division is not
considering making changes to the Toxicity program at this time.
3. Since Contentnea Creek is not currently listed [2016 303(d) List] as impaired for Turbidity,
the limit for this parameter has been removed.
Concurrent with this notification, the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Wilson County area, as
required by the NPDES Program. Please provide your comments, if any, to me via email
[[e-mail]] or write to my attention care of DEQ/DWR/NPDES Program no
later than July 27, 2018. Your written comments are welcome but not mandatory. Following the
mandatory 30-day public comment period, the Division will review all pertinent comments on
your permit draft, and take appropriate action prior to issuing your NPDES permit final.

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:
a. measure flow continuously via weir or flow meter(totalizer preferred);
b. estimate flow at 20-minute intervals during the entire discharge event;
c. report flow based on discharge pump logs; or
d. calculate flow based on total rainfall per unit area draining to the outfall using the
Rational Method[see formula, Section A. (2.)].
3. Where possible, the grab sample for Oil&Grease should be skimmed from the water surface of a

A. (2.) FLOW MEASUREMENT RATIONAL [G.S. 143-215.3(a)(2)]
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.

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 defmed 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% (defmed 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 fmal effluent
discharge below all treatment processes.
gw Vim,,
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 fmal day of the third month.
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.
as specified in the cited document, such as minimum control
NOTE: Failure to achieve test conditions porganism
environmental controls, shall constitute an invalid test and will
survival and appropriaterequire 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.
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
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:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
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).

NPDES Permit NC0089087
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-
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 tF
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
4. Signatory Requirements 'Supplements Section B. (11.)(b) and Supersedes Section B.(11.)(d)]
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section
B. (11.)(a)or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A
person, and not a position,must be delegated signatory authority for eDMR reporting purposes.
For eDMR submissions,the person signing and submitting the DMR must obtain an eDMR user account and
login credentials to access the eDMR system. For more information on North Carolina's eDMR system,
registering for eDMR and obtaining an eDMR user account,please visit the following web page:
