Footnotes:
1. The permittee shall begin submitting discharge monitoring reports electronically using the NC
DWR's eDMR application system [see A. (4)].
2. The Division shall consider all effluent TRC values reported below 50 µg/1 to be in compliance with
the permit. However, the Permittee shall continue to record and submit all values reported by a
North Carolina certified laboratory (including field certified), even if these values fall below 50 µg/l.
Page 3 of 8

Permit NCO046345
3. Fluoride should be monitored if the Permittee backwashes with fluoridated finished water.
4. Zinc should be monitored if the Permittee adds zinc orthophosphate as a corrosion inhibitor prior
to backwashing.
5. Effluent hardness sampling should be performed in conjunction with testing for hardness
dependent metals (cadmium, copper, lead, nickel, silver, and zinc).
6. The Permittee shall sample instream hardness, upstream of the facility's discharge. The sample
shall be representative of the hardness in the receiving stream. If the Permittee is a member of the
Monitoring Coalition Program, sampling for instream hardness may be waived as long as the
Monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum
frequency of quarterly, and the Permittee has obtained approval from DWR-NPDES Permitting Unit
that the upstream station being monitored by the Coalition is representative of the receiving
stream for this discharge. The Permittee is responsible for submitting instream hardness test
results with its permit renewal application package. If Coalition membership is cancelled or the
Coalition terminates instream hardness sampling at the approved station, the Permittee will
immediately notify the Division and resume sampling for instream hardness, upstream of its
discharge.
7. Ammonia nitrogen should be monitored if the Permittee uses chloramines (adds ammonia to
chlorinated water) for secondary disinfection prior to backwashing.
8. Chronic Toxicity Monitoring P/F (Ceriodaphnia dubia) @ 90.0% during the months of January,
April, July, and October [see A. (2)].
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN
TRACE AMOUNTS.
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 90.0%.
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
Page 4 of 8

Permit NCO046345
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) PERMIT RE -OPENER: WHOLE EFFLUENT TOXICITY
[G. S. 143-215.1(b)]
Whole Effluent Toxicity monitoring results indicating aquatic toxicity may result in the
Division of Water Resources re -opening this permit or requesting by letter that further
action be taken. Additional metals testing, a toxicity identification evaluation, a toxicity
reduction evaluation, and/or an assessment of discharge treatment alternatives may be
requested.
A. (4) ELECTRONIC REPORTING OF MONITORING REPORTS
[NCGS 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

I. Reporting Requirements [Supersedes Section D. 12.1 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.
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)).

http://www2 epa Gov/compliance/final-national-pollutant-discharge-ehmination-
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:

Facility Summary
This facility is a conventional water treatment plant with discharge of filter backwash wastewaters with a
design potable flowrate of 9.0 MGD and a maximum, monthly average wastewater discharge of 0.582
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 Jan2014-Jan2017:
[Maximum, Monthly reported flow = 0.582 MGD]
Toxici 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
Uctober[TGP3B]. Nine (9) out of eighteen (18) (with a pass rate of 50%) toxicity tests were reported as
"FAIL" within four and a half years (January2012-July2016). A special condition [Section A.(3.)] is added
for discharge alternatives evaluation because of the two (2) toxicity failures within the most recent four (4)
quarters. See attached data spreadsheet.
Fact Sheet
Renoval 2017 -- NPDES Pcnilit NCO046345

• The monitoring frequency for total suspended solids, total residual chlorine, and turbidity have
been increased from 2/Month to weekly as the facility had a maximum, monthly average
wastewater flow greater than 0.5 MGD.
• Data in lab sheets provided by permittee were used over data in BIMS where applicable in RPA
• Removed footnote "Parameter should be monitored in conjunction with toxicity test" per WTP
updated guidelines
• Total hardness and ammonia nitrogen added to permit per WTP guidelines
• Limit for copper added based on RPA
• Address updated from 275 Reid Lake Road to 278 Reid Lake Road per permit application
• Updated Creek name from Little Troublesome Creek to Troublesome Creek, stream ID from 16-
6-(3) to 16-6-(0.3), and classification from WS-V to WS-III on supplement to permit sheet per
BIMS data

Stream — Discharge from WTP for Outfall 002 is into an unnamed tributary to Troublesome Creek
[Stream Segment 16-6-(0.3)]. This segment is currently not listed as impaired on the 2014 North Carolina
303(d) List.
RPA:
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of V2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between August 2012 and
January 2017. Pollutants of concern included toxicants with positive detections and associated water
quality standards/criteria. Based on this analysis, the following permitting actions are proposed for this
permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality -based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water
quality standards/criteria: Copper
• Monitoring Only: The following parameters will not receive a limit, since they did not demonstrate
reasonable potential to exceed applicable water quality standards/criteria, but the maximum
predicted concentration was >50% of the allowable concentration: Fluoride
• No Limit: The following parameters will not receive a limit, since they did not demonstrate
reasonable potential to exceed applicable water quality standards/criteria and the maximum
predicted concentration was <50% of the allowable concentration: Zinc
• Summary of new limits added based on RPA: Copper will attain limits of. Acute —11.02 ug/l;
Chronic: 8.26 ug/l
• Summary of existing limits deleted based on RPA: None

"I reviewed the permit. My only comment is the supplemental cover page seems to indicate there is a
monthly flow average limit of 0.582 MGD. I know you are saying that the facility discharges this average
flow. I recommend the wording be changed to show that the average flow for this facility is 0.582 MGD
and this is not to be taken as a flow limit. See limit page for clarification. Recommend the permit be
reissued with above comment."

Dear Mr. Eason:

Subject: Request for Additional Information
NPDES Renewal Application
Reidsville WTP
NPDES permit NCO046345
Rockingham County
The Division has reviewed your application, received on December 28, 2015, for renewal of NPDES permit
NC0046345. To enable us to complete our review in accordance with N.C.G.S. 143-215.1 and 15A NCAC
2H.0105, please provide additional or revised information to address the following comments:
1. Please provide five (5) days of Total Hardness (CaCO3 or (Ca + Mg)) data for the water treatment
plant effluent and upstream from Outfall 002 for Little Troublesome Creek.
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. The metals of concern for the Reidsville WTP permit are Total Copper and Total Zinc.
If no response is received within 60 calendar days [per 15A NCAC 2H.0107(b)], the permit will be renewed
without the benefit of the additional information. Therefore, a default hardness of 25 mg/L (CaCO3 or (Ca +
Mg)) will be used to calculate an effluent limit for Total Copper giving a daily maximum limit of 10.47
µg/L, and for Total Zinc, giving a daily maximum limit of 125.7 µg/L.
If you have any questions, please contact Meredith Wojcik at 919-807-6479 or email at
[e-mail].
Sincerely,

DMR Data for Copper&Fluoride NC0046345.xlsx
Hello,
I am currently working on renewing the Reidsville WTP permit (NC0046345) and I have noticed some problems with the
monitoring data. I am specifically looking at the metals data for Fluoride and Copper and there seems to be a
discrepancy in units between mg/L and ug/L without a corresponding change in the values reported that you would
expect between milligrams and micrograms. I have attached a spreadsheet showing the data in question.
We need a response clearing up this issue with the units in order to continue the process of renewing the permit.
Thank you,
Meredith Wojcik
