Subject: Issuance of NPDES Permit NC0088200
City of Thomasville WTP
Class PC-1
Davidson County
Dear Mr. Craver:
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.
We have made the following changes from the draft permit mailed to you:
➢ The monitoring requirement for flow has been changed from a monitoring frequency of twice
a month to continuous and the sample type has been changed from instantaneous to
recording. This is in accordance with policy requiring facilities with discharges over 50,000
gallons per day to conduct continuous monitoring.
➢ Monitoring requirements for effluent hardness sampling have been added with a monitoring
frequency of quarterly.
We have made the following updates to your previous permit, as reflected in your draft permit:
➢ The limit for flow has been removed.
➢ As mentioned in your letter, flow monitoring has been corrected from instantaneous to
continuous monitoring as the facility has flow greater than 0.050 MGD.
➢ Groundwater monitoring requirements have been removed.
➢ Monitoring requirements for iron, manganese, calcium, and magnesium have been removed
as water quality standards do not exist for these parameters.
➢ Monitoring requirements for zinc and ammonia nitrogen have been removed as the facility
does not use zinc orthophosphate nor chloramines.
➢ Monitoring frequencies for fluoride and copper have been reduced from monthly to quarterly
to align with quarterly toxicity monitoring.
➢ Turbidity monitoring requirements have been added due to U.S. requirements.
➢ Section A. (3) has been added to require electronic submission of effluent data. Federal
regulations require electronic submittal of all discharge monitoring reports (DMRs), effective
December 21, 2016.
➢ Regulatory citations have been added to the permit.
➢ An updated outfall map has been included.
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.

l..
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 sampling has been added to
this permit at a monitoring frequency of quarterly. See Section A.(2.) Effluent Limitations and
Monitoring Requirements.
No later than 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 A. (3)] For information on eDMR, registering for eDMR and obtaining an
eDMR user account, please visit the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr.
For more information on EPA's final NPDES Electronic Reporting Rule, please visit the following
web site:
http://www2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes-
electronic-reporting-rule.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing, upon written request submitted within
thirty (30) days after receiving this letter. Your request must take the form of a written petition
conforming to Chapter 150B of North Carolina General Statutes, and you must file it with the Office
of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless
such a demand is made, this permit shall remain 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 questions, or if we can be of further service, please contact Meredith Wojcik at
[[e-mail]] or call [phone].

Permit NC0088200
A. (2) CHRONIC TOXICITY MONITORING (QUARTERLY)
[15A NCAC 02B.0500 et seq.]
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December
2010, or subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The
testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. 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.
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 TGP3B. Additionally, DWR Form AT-1 (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 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. Upon submission of a valid test, this monthly
test requirement will revert to quarterly in the months specified above.
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 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. (3) ELECTRONIC REPORTING OF MONITORING REPORTS
[NCGS 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.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements ISupersedes Section D. (2.) and Section E. (5.) tag
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:
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.

Permit NC0088200
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-npde s-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:

Facility Summary
This facility is a conventional water treatment plant with discharge of alum sludge wastewaters backwashed
from filters after flocculation and settling in sedimentation basins with a design potable flowrate of 6.0
MGD and a maximum, monthly average wastewater discharge of 0.177 MGD based on data submitted.
Because the waste flow is >0.050 MGD, continuous flow monitoring is required.
Monthly average FLOW (MGD) — Last 36 months August 2013-July 2016*:
[Ave 0.159 MGD; Maximum, Monthly reported flow = 0.177 MGD]
*NOTE: There were only three data points
Toxicity —This permit requires Chronic Whole Effluent Toxicity (WET) testing using Ceriodaphnia dubia
to be performed as 7-day pass/fail test at 90% effluent concentration, during January, April, July, and
October. Only one toxicity test was conducted over the last 4 % years, all others were waived. The facility
did pass the one toxicity test, which was conducted in July 2016.
Renewal Summary —
• Removed flow limit
• Monitoring for calcium and magnesium were removed as per the October 2009 WTP strategy;
there is no water quality standard for calcium nor magnesium
• Monitoring requirements for zinc and ammonia nitrogen were removed as the facility currently
does not use zinc orthophosphate nor chloramines
Fact Sheet
Renewal 2016 -- NPDES Permit NC0088200
Page 1

• Monitoring requirement for effluent hardness was added as there is sampling for a hardness
dependent metal, copper. There is no instream monitoring for hardness due to a summer 7Q10 of
zero.
• Monitoring frequencies for fluoride and copper were reduced from monthly to quarterly in
accordance with the October 2009 WTP Strategy
• Turbidity monitoring added
• Iron and manganese monitoring removed, as no water quality standard exists
• Groundwater well monitoring requirements removed, as per Julie's note
Stream — Discharge from WTP for Outfall 001 is into an unnamed tributary to Rich Fork Creek [Stream
ID: 12-119-7]. This segment is not currently listed as impaired in the 2012 North Carolina 303(d) List.
RPA — A Reasonable Potential Analysis (RPA) was conducted on copper and zinc effluent parameters data.
For zinc, Discharge Monitoring Reports (DMRs) did NOT report concentrations above method -detection
levels (MDLs) for the past four and a half (4 t/z) years (February 2012 July 2016), unless otherwise noted). It
should be noted that there were only two data points. For copper, Discharge Monitoring Reports (DMRs) did
report concentrations above method -detection levels (MDLs) for the past four and a half (4 %) years. There
was RP, however the small dataset (3 samples) had no values over the allowable Cw, therefore quarterly
monitoring is recommended. For fluoride, there was one reported concentration above method -detection
levels (MDLs) for the past four and a half (4 '/2 years). Fluoride demonstrated no RP, however, quarterly
monitoring is recommended due to the small number of data points.

RE: Draft NPDES Permit NC00S8200
City of Thomasville
RECEIVED/NCDEQ/Q' R
OCT 81 2016
Water Quality
Permitting Section
Dear Ms. Wojcik,
The City of Thomasville has received and reviewed the draft NPDES permit for the Water Plant's
waste alum lagoon discharge. We have the following questions and concerns and would like
additional clarification or changes as noted.
1. Flow — The permit lists instantaneous flow measurement is required in section A.(1). In the
Expedited Fact Sheet under the Facility Summary the statement is made that `Because the waste
flow is > 0.050 MGD continuous flow monitoring is required." In addition, in section A.(1) 2. it
states that for instantaneous flow monitor the duration of the discharge must be reported.
There appear to be two contradictory recommendations in the packet of information
regarding flow monitoring. Since flow occurs mostly continuously at the alum lagoon unless
debris plugs the flow meter it would make it difficult to report a duration of the flow. It
would seem that the more reasonable method of flow monitoring would be metered (as per
possible choices on the E-DMR). The flow meter installed at the lagoon now is capable of
providing a metered total daily. This would be far less ambiguous than an instantaneous
flow.
2. Toxicity — Section A.(1)5. of the permit lists a Ceriodaphnia dubia 7-day pass/fail toxicity test
requirement. In the Expedited Fact Sheet, a 24 day pass/fail test is required.
We are assuming this recommendation is a typographical error and that you are requiring a
7 day test as this is what is in the draft permit. If not, please clarify what test period is
required.
3. Zinc — In the Expedited Fact sheet it states in the Renewal summary that zinc is being removed
and also that it is being reduced from monthly to quarterly.
The draft permit does not include zinc, so the implication is that zinc is indeed being
removed. Again, this is just a matter of clarification.
If any further information is required, please notify Mr. Kelly Craver or myself as soon as possible.

POINT SOURCE BRANCH
The City of Thomasville WTP respectfully submits one original and 2 copies of the permit application
for renewal of Permit #NC0088200. Supporting information includes the application, topographic
maps, and notes on the preparation of the application, A Sludge Management Plan, as such is not
included, but is noted on the application that all solids are discharged for treatment to the City's
Hamby Creek Wastewater Treatment Plant. In addition, a PPA (Priority Pollutant Analysis) has not
been included, because there is no discharge to the Alum Lagoon, and thus to the creek to take a
sample of for analysis. Although wastewater discharge from this facility has ceased at this time, the
City does not wish to rescind this permit at this time. Evaluations are still being made to determine the
future of this waste treatment lagoon and feasibility options for other waste treatment solutions.
Please do not hesitate to contact me for any questions regarding this application.
