Subject: Final NPDES Permit Renewal
Permit NCO037834
Archie Elledge WWTP
Forsyth County
Class IV Facility
SIC code 4952
Dear Ms. Driver:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. 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 following addition was made to the final permit and was not in the draft permit sent to you on
November 30, 2016:
• Effluent data reported for silver was all less than detection at a detection level of less than
5 µg/L or 2 gg/L. In accordance with 15A NCAC 2B. 0500 all test procedures must
produce detection and reporting levels that are below the permit discharge requirements.
All data generated must be reported to the approved detection level or lower reporting
level of the procedure. Currently, DWR's laboratory identifies the Practical Quantitation
Level (PQL) for silver at < 1 µg/L. The allowable discharge concentration for your
facility is 0.079 µg/L. Therefore, future sampling for silver as part of the facility's
Pretreatment Program and Effluent Pollutant Scan should sample silver down to the
lower reporting level of the procedure which is < 1 gg/L. No limits or additional
monitoring requirements for silver were added to the permit at this time.
• Monitoring for zinc will remain in this permit. Monitoring for copper shall continue as a
part of your Pretreatment Program. Zinc and copper are parameters of concern since the
receiving stream is listed as impaired for these parameters on the 2014 303(d) list.
• The measurement frequency and sample type for the Effluent Pollutant Scan in Section
A. (1) have changed in format to direct you to footnote 11.
• Footnote 12 in A. (1) has been updated to "Effluent hardness samples shall coincide with
sampling for metals at least quarterly."

• The expiration date has been extended from June 30, 2019 to June 30, 2022.
• The years identified for the Effluent Pollutant Scan in A. (3) have changed from 2016,
2017, and 2018 to 2017, 2019, ad 2021 due to the permit expiration change to June 30,
2022. Section A. (3) has been updated to the current version.
• The Effluent Pollutant Scan has been updated to include the text "Monitor and Report" in
Section A. (1).
• The mercury minimization plan (IvIMP) in Section A. (5) shall be developed by January
28, 2018 and the condition has been updated to reflect that date and the current website
link.
• Required units of measurement have been included for all parameters in Section A. (1).
• The parameter code for Total Phosphorus has been corrected.
• Footnote 3 in Section A. (1) has been simplified regarding 2/week monitoring for select
parameters.
• Footnote 1 in Section A. (1) has peen updated since the December 21, 2016 eDMR
deadline has passed.
• Footnote 9 in Section A. (1) has been added in order to specify the sampling detection
level for cyanide compliance.
• The monitoring frequency for Total Nitrogen and Total Phosphorus in Section A. (1) has
changed from weekly to monthly per 15A NCAC 2B .0500. Weekly samples are no
longer needed for the Yadkin Pee -Dee River Basin nutrient management strategy.
This final permit contains the following changes from your previous permit:
• 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 NPDES Permitting Unit 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. Further, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have
hardness -dependent equations. As a result, the NPDES Permitting Unit will need site-
specific effluent hardness data and instream hardness data, upstream of the discharge, for
each facility monitoring these metals in order to calculate permit limitations. Effluent
hardness and instream hardness sampling, upstream of the discharge, has been added to
this permit at a monitoring frequency of quarterly. See Section A. (1) Effluent Limitations
and Monitoring Requirements [footnote 12 and 13].
• Reduction in monitoring frequency from daily to 2/week has been included for the
influent and effluent parameters BOD, TSS, fecal coliform and ammonia nitrogen based
on exceptional facility performance over the past three years [15A NCAC 2B
.0508(b)(1)].
• Quarterly cadmium monitoring has been included in Section A. (1) and should be
sampled at the Practical Quan.ification Level (PQL) of 0.5 µg/L. This metal is currently
reported at levels less than 5 pg/L and 2 µg/L but the permittee is required to report the
results at the Practical Quante kation Level (PQL) since the allowable discharge
concentration is 1.74 gg/L.

Page 13
• Winter ammonia nitrogen limits have been lowered to 2.4 mg/L monthly average and 7.2
mg/L weekly average based on the ammonia nitrogen waste load allocation calculation to
protect for EPA's chronic/acute ammonia criteria. These limits will be effective May 31,
2018 due to current construction upgrades affecting flow paths between Archie Elledge
WWTP and Muddy Creek WWTP.
• Monitoring for fluoride and copper has been removed from A. (1) Effluent Limitations
and Monitoring Requirements based on no reasonable potential to exceed water quality
standards.
• The monitoring frequency for zinc has been reduced from monthly to quarterly in Section
A. (1). The reasonable potential analysis did not indicate potential to exceed water quality
standards for zinc; however, the receiving stream is listed as impaired for zinc on the
2014 303(d) list so quarterly monitoring is maintained.
• Quarterly monitoring for dichlorobromomethane and chlorodibromomethane has been
added to the permit based on reasonable potential analysis to exceed human health water
quality criteria.
• The limits and monitoring of mercury have been removed from A. (1) Effluent
Limitations and Monitoring Requirements based on the TMDL evaluation. Sampling for
mercury will be conducted during the 3 effluent pollutant scans [see A. (3)].
• Effluent Pollutant Scan frequency has changed from annual to 3 times per permit cycle
[see A. (3)].
• Section A. (5) has been added to require a Mercury Minimization Plan (MMP) based on
the statewide mercury TMDL approved by EPA in 2012.
• Section A. (6) has been added to include a nutrient reopener for High Rock Lake.
• Section A. (7) has been added to include a schedule of compliance for the winter
ammonia nitrogen limits, effective on May 31, 2018.
• Gravity belt thickener and flow equalization facilities have been added to the supplement
to permit cover sheet on page 2 of 11.
• Regulatory citations have been added to the permit.
• Parameter characteristic codes have been added in Section A. (1).
• An updated outfall map has been included with updated coordinates for Outfall 001.
• The total residual chlorine limit is expressed as a daily maximum instead of a daily
average.
• 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. 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. (8)].
For information on eDMR, registering for eDMR and obtaining an eDMR user account,
please visit the following web page: http://deq.ne.gov/about/divisions/water-

This discharge ultimately flows to High Rock Lake, which is listed as impaired on the 2014 303(d)
list for chlorophyll -a due to excessive nutrient inputs. A TMDL is currently in progress, and
nutrient limitations are a potential future requirement.
Please note that the receiving stream is listed as impaired for zinc and copper on North Carolina's
2014 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division,
and instream data will continue to be evaluated. If there is noncompliance with permitted effluent
limits and the stream impairment can be attributed to your facility, then mitigative measures may
be required.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-
6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect
the legal requirements to obtain other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental permits that may be required.
If you have any questions concerning this permit, please contact Jennifer Busam at [phone]
or via email at [e-mail].

A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 76 %.
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
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.
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 on the Effluent
Discharge Monitoring Form (MR -1) for the months in which tests were performed, using the parameter
code TGP313 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:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 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, 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 third month.
Page 5 of 11

Permit NCO037834
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 monitoring regw-rements 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. (3) EFFLUENT POLLUTANT SCAN
[NCGS 143-215.1 (b)]
The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below.
One scan must be performed in each of the following years: 2017, 2019 and 2021. Analytical methods
shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether
parameters are present in concentrations greater than applicable standards and criteria. Samples should
be collected with one quarterly toxicity test each year, and must represent seasonal variation [i.e., do not
sample in the same quarter every year]. Unless otherwise indicated, metals shall be analyzed as "total
recoverable."

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.
Page 8 of 11

Permit NC0037834
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).
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
Page 9 of 11

Perimt NCO037834
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: https://www.federalre 'ster.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:
