Subject: Final NPDES Permit Renewal
Permit NC0041696
Lake Rhodhiss WWTP
Burke County
Facility Class IV
SIC Code 4952
Dear Mr. Padgett:
Interim Director
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 Division received comments from the permittee on the draft permit after the public comment period was
ended. The permittee requested to modify the proposed permit to remove instream monitoring requirements,
mercury minimization plan and ammonia nitrogen limitations for 7.5 MGD flow and monitoring frequency for
3.5 MGD, 7.5 MGD and 10.5MGD permitted flow. The Division can not fulfill these requests as these permit
conditions and permit limits were developed according to current laws and regulations.
The final permit maintains the following significant changes identified in the letter sent on October 3,
2017:
• Removed monitoring requirements for total copper from 7.5 MGD and 10.5 MGD permitted flows
based on the results of the Reasonable Potential Analysis (RPA). There were no copper monitoring
requirements for 3.5 MGD flow in the previous permit. The permittee will continue to monitor total
copper under the pretreatment program.
• Removed limits and monitoring requirements for total selenium and total silver for all permitted
flows based on results of RPA. However, the facility will continue to monitor these metals under
the pretreatment program.
• Reduced the frequency of monitoring for total nitrogen and total phosphorous from weekly to
monthly due to the change in impairment status of Lake Rhodhiss which is no longer listed in 303d
list.

• Reduced the frequency of effluent pollutant scan from annual to three times during the permit period
and added the language for toxicity testing requirements in A. (7) Effluent Pollutant Scan.
• Added requirements to notify the Division of Water Resources (DWR) upon reaching an annual
average daily flow equal or greater than 2.8 MGD to ensure compliance with 7.5 MGD effluent
limitations. (See Supplement to Permit Cover Sheet)
• Added monitoring requirements for Total Monthly Flow (TMF) for the permitted flow of 10.5 MGD
required to calculate monthly nutrient loads. (See A. (3) and A. (6))
• Added monthly average and weekly average effluent limits for ammonia nitrogen for the permitted
flow of 7.5 MGD as per NPDES Permitting Guidance to implement ammonia chronic criteria. (See
A.(2))
• Monitoring frequency for ammonia nitrogen has been changed from weekly to daily for 3.5 MGD,
7.5 MGD and 10.5 MGD permitted flows according to 15A NCAC 2B.0500 for class IV wastewater
treatment facility.
• Added daily monitoring of effluent temperature for permitted flows of 3.5 MGD, 7.5 MGD and
10.5 MGD as per requirements in 15A NCAC 2B.0500. (See A.(1), A. (2) and A. (3))
• Added effluent and instream monitoring requirements for conductivity for permitted flows of 3.5
MGD, 7.5 MGD and 10.5 MGD because the facility treats industrial discharges with domestic
wastewater and it has a pretreatment program. (See A.(1), A. (2) and A. (3))
• Added minimum daily average limit of 5 mg/1 for oxygen in permitted flows of 3.5 MGD, 7.5 MGD
and 10.5 MGD as per 15A NCAC 2B.0200.
• Added Mercury Minimization Plan (MMP) to the permit according to the DWR Statewide Mercury
TMDL implementation guidance (See Special Condition A. (8)). This condition was modified from
the draft permit to add interim date. The Town of Valdese will be responsible for implementing this
plan.
The pennittee requested to reconsider MMP requirements for the facility. However, this is a
programmatic change that requires approval by the EMC. NPDES will seek to change appropriate
revisions to the NPDES implementation of the Mercury Minimization Program (MMP); however to
protect for human health based on a fish tissue target of .3 mg/kg MMPs will continue to be required
for large municipal wastewater treatment plants greater than 2 MGD with significant quantities of
mercury greater than 1 ng/L. NPDES hopes that when Dental Effluent Guidelines requiring
amalgam separators for existing sources becomes effective (July 14, 2020) there will no longer be a
need for MMPs since most of the municipality MMPs focus on mercury reductions from Dental
offices.
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (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-

Page I3
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 and upstream hardness have been added
to this permit at a quarterly monitoring frequency. Hardness sampling should be performed in
conjunction with testing for metals.
• 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) interne application has been
added to this permit. [See Special Condition A (9)]

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.

A. (4) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) @ 3.5, 7.5, 10.5 MGD
[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 2.4% at 3.5 MGD; 4.9% at 7.5 MGD; 6.7% at 10.5 MGD.
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 TGP3B 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 6 of 13

Permit No. NC0041696
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. (5) TOTAL NITROGEN AND PHOSPHOROUS LIMITS [G.S. 143-215.1(b)]
Total Nitrogen (TN) load limits and Total Phosphorus (TP) load limits are annual limits and apply on a calendar
year basis.
A. (6) CALCULATION OF NUTRIENT LOADS [G.S. 143-215.1(b)]
(a) The Permittee shall calculate annual nutrient loads as follows:
(i.) Monthly TN (or TP) Load (lb/mo) = TN (or TP) x TMF x 8.34
where:
(b)
TN or TP = the average Total Nitrogen or Total Phosphorus concentration (mg/L) of
the composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TP (or TN) Load (lb/yr) = Sum of the 12 Monthly TP (or TN) Loads for the calendar year
The Permittee shall report monthly Total Nitrogen and Total Phosphorus results (mg/L and lb/mo) in the
appropriate discharge monitoring report for each month; and each calendar year's results (lb/yr) with the
December report for that year

Reporting. Test results shall be reported electronically via eDMR or on DWR Form — DMR-PPA-1 (or on a
form approved by the Director) by December 3151 of each designated sampling year. The report shall be
submitted to the following address:
NC DEQ / DWR / Central Files, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617.
Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional
toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5) and EPA Municipal
Application Form 2A. The US EPA requires four (4) toxicity tests for a test organism other than the test species
currently required in this permit. The second species tests should be conducted either quarterly for a 12-month
period prior to submittal of the permit renewal application, or four tests performed at least annually in the four
and one half year period prior to the application. The second species tests must be multiple concentration (5
concentrations plus the control). These tests shall be performed for acute or chronic toxicity, whichever is
specified in this permit. POTWs performing NPDES chronic Ceriodaphnia testing should perform chronic
Fathead minnow testing. POTWs performing NPDES acute Fathead Minnow testing should perform acute
Ceriodaphnia testing. POTWs performing NPDES chronic Mysid shrimp testing should perform chronic
Silverside Minnow testing.
The second species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following
address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional
toxicity tests and reporting requirements. Results should also be summarized in Part E (Toxicity Testing Data) of
EPA Municipal Application Form 2A, when submitting the permit renewal application to the NPDES Permitting
Unit.
A. (8) MERCURY MINIMIZATION PLAN (MMP) [G.S. 143-215.1(b)]
The permittee shall develop and implement a mercury minimization plan during this permit term. The MMP shall
be developed by August 1, 2018, and shall be available for inspection on -site. A sample MMP was developed
through a stakeholder review process and has been placed on the Division website for guidance
(http://deq.nc.gov/about/divisions/water-resources/water-resources-permits/wastewater-branch/npdes-
wastewater-permits, under NC Model Mercury Minimization Plan). The MMP should place emphasis on
identification of mercury contributors and goals for reduction. Results shall be summarized and submitted with
the next permit renewal. Performance of the Mercury Minimization Plan will meet the requirements of the
TMDL (Total Maximum Daily Load) for mercury approved by USEPA on October 12, 2012, unless and until a
Waste Load Allocation specific to this facility is developed and this NPDES permit is amended to require further
actions to address the Waste Load Allocation.
A. (9) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports.

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).
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.
Page 10of13

Permit No. NC0041696
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:
https://www. federalregister. 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:
http://deq.nc.gov/aboutldivisions/water-resources/edmr
4. Sianatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)l
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:

Briefly describe the proposed permitting action and facility background: The Town of Valdese has requested
renewal of the NPDES permit for Lake Rhodhiss Wastewater Treatment Plant. The existing WWTP has
a design capacity of 7.5 MGD but currently is authorized to discharge 3.5 MGD to Lake Rhodhiss, a class
Page 1of15

WS-IV, B, CA waters. The class denotes use as a water supply, primary recreation and critical area
waterbody. The facility serves the Towns of Valdese, Drexel, and Rutherford College in addition to Burke
County for an estimated total of 8,200 persons treating both domestic and industrial wastewater. Lake
Rhodhiss was impaired for pH beginning with the 2006 303d list but was removed in 2014.
The permittee requested an additional effluent limitation and monitoring page for 3.5 MGD flow in the
previous permit renewal application in 2009 due to reduced industrial wastewater flow to the facility. The
current permit has tiered effluent pages for 3.5, 7.5 and 10.5 MGD flow. Average daily flow rates in
2012, 2013 and 2014 were 2.4 MGD, 2.5 MGD and 1.75 MGD respectively. The flow rate did not go
above 1.6 MGD in 2017 to date.
The treatment plant has a pretreatment program and a Long Term Monitoring Plan (LTMP) as it receives
flow from 9 noncategorical Significant Industrial Users (SIUs) and one Categorical Industrial User. The
permitted flow from the industrial users is 3.18 MGD but the average industrial flow in 2016 was 1.24
MGD. The facility will continue to implement its existing pretreatment program and monitor all
parameters as required.

4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions
when model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to
verify model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other
instream concerns. Instream monitoring may be conducted by the Permittee, and there are also
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
Page 3 of 15

If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: The current permit requires instream monitoring for dissolved oxygen and temperature.
Instream data from January, 2012 to April, 2017 were reviewed. There were no apparent differences in
the upstream and downstream dissolved oxygen concentration and temperature in the samples taken
during the same time period. The dissolved oxygen level in the stream was above 6.5 mg/1 during this
time period. As a major facility with industrial sources, instream monitoring for conductivity will be
added in conjunction with dissolved oxygen and temperature to this permit.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): N
Name of Monitoring Coalition: NA
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): The compliance data from
January, 2012 to April, 2017 was reviewed. The permittee received a total of 15 notice of violations for
exceeding limits for TSS and fecal coliform, and violating monitoring frequency of BOD and TKN. The
permittee violated TSS limits 8 times. There are 12 enforcement cases filed against the facility for
violating TSS and BOD weekly and monthly average effluent limits. The facility has paid $13664.64 in
fines during this period. The ARO is working with the facility to monitor the facility's compliance
performance.
Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): The facility passed 20 of 20 quarterly chronic toxicity tests as well as all 4 second species
chronic toxicity tests. The facility passed all four second species toxicity tests at the effluent
concentration above 9.2%.
Summarize the results from the most recent compliance inspection: One compliance inspection was
conducted in March, 2015. The facility was found well maintained and operated during this inspection.
6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/1 for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: Effluent BOD limits
after facility expansion to 10.5 MGD are stringent than TBELs. These limits are based on speculative
limits given to the facility in 1998 using the Best Professional Judgement (BPJ).
Page 4 of 15

Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/1 (summer) and 1.8 mg/1 (winter). Acute ammonia limits are derived from chronic criteria,
utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals.
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ugfl) and capped at 28 ug/1 (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: Ammonia
nitrogen monitoring for 3.5 MGD and Ammonia nitrogen limits for 10.5 MGD flow will remain the same.
New ammonia nitrogen limits based on waste allocation calculations for receiving body are proposed for
7.5 MGD flow rate. No changes in TRC limits are proposed.
Reasonable Potential Analysis (RPA) for Toxicants
If applicable, conduct RPA analysis and complete information below.
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 %s detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effejctive 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.
Three reasonable potential analyses were conducted for permitted flows of 3.5 MGD, 7.5 MGD and 10.5
MGD using the effluent toxicant data collected between September, 2013 and April, 2017. Pollutants of
concern included toxicants with positive detections and defined water quality standards/EPA criteria.
Based on these analyses, 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: None for all three permitted flows
• Monitoring Only. The following parameters will receive a monitor -only requirement 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: None for
all three permitted flows
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, 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: Arsenic, Cadmium, Chlorides, Chromium, Copper, Cyanide, Lead,
Molybdenum, Nickel, Selenium, Silver, Sulfates, Zinc and Total Phenolic Compounds. These
compounds will be monitored in pretreatment program during this permit cycle.
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None
Page 5 of 15

o The following parameter(s) will receive a monitor -only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None

Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program.:
Attached both Documents.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several
exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in
NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test
failure.
Describe proposed toxicity test requirement: This is a major POTW, and a quarterly chronic WET limit
at 2.4% effluent concentration using Ceriodaphnia dubia was required during previous permit period.
These requirements will continue in this permit. For 7.5 MGD and 10.5 MGD flows, a quarterly chronic
WET limit at 4.9 % and 6.7 % effluent concentration using Ceriodaphnia dubia will be required
respectively.
Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply
with EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/l) will
receive an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a
pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed
the WQBEL value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL
value of 47 ng/1.

Describe proposed permit actions based on mercury evaluation: Majority of the mercury data reported
on DMRs were not measured using EPA method 1631 E. The permittee was informed to use the method
1631E on all future analyses.
Based on the mercury evaluation results that were available and did use method 1631 E, no annual
average mercury concentration exceeded the WQBEL, and no individual mercury sample exceeded the
TBEL, in this case no mercury limit is required. However, since the facility is >2 MGD and reported
quantifiable levels of mercury (> 1 ng/1), a mercury minimization plan (MMP) has been added to this
permit.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: Lake Rhodhiss was listed in303d list for high pH beginning in 2006 which indicated
high algal growth in the lake. Based on this impairment, a Lake Rhodhiss Management Strategy was
developed for point and non point sources in 2010. During previous permit cycle, nutrient monitoring
and mass load limits were proposed based on this strategy. Lake Rhodhiss was removed from 303d list in
2014 as it was no longer impaired for pH. Due to lower pH and algal growth in the lake, the Division
decided to change nutrient monitoring frequencies from weekly to monthly and eliminate instream
monitoring requirements for four facilities (Marion, Morganton, Lenoir and Valdese) discharging to Lake
Rhodhiss. This permit reflects these changes in nutrient monitoring for 3.5 MGD, 7.5 MGD and 10.5
MGD flows. The nutrient mass load limits for 10.5 MGD flow after expansion of the facility will remain
the same during this permit period.
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: N/A
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H. 0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA

7. Technology -Based Effluent Limitations (TBELs)
Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l
BOD5/TSS for Monthly Average, and 45 mg/1 for BODS/TSS for Weekly Average). YES
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA
Are 85% removal requirements for BOD5ITSS included in the permit? YES
If NO, provide a justification (e.g., waste stabilization pond). NA
If any limits are based on best professional judgement (BPJ), describe development: NA
Document any TBELs that are more stringent than WQBELs: NA
Document any TBELs that are less stringent than previous permit: NA
8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit
must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all
cases, existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA
9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): NO
If YES, confirm that antibacksliding provisions are not violated: NA
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
Page 8 of 15

considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring, refer to Section 4.
11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was fmalized on December 21, 2015. Effective
December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to
submit additional NPDES reports electronically. This permit contains the requirements for electronic
reporting, consistent with Federal requirements.

NPDES Implementation of Instream Dissolved Metals Standards - Freshwater Standards
The NC 2007-2015 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as
approved.

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness -dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness
and so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on that
below), but it is also possible to consider case -specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WOBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below
detection level), then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates
the 1Q10 using the formula 1Q10 = 0.843 (s7Q10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern and for
each individual discharge, the Permit Writer must first determine what effluent and instream
(upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
Page 13 of 15

If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and
upstream hardness samples over a period of one week. The RPA is rerun using the new data.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
_ (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) x (s7Q10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1 Q 10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any
have been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in -stream
ambient conditions. This factor is calculated using the linear partition coefficients
found in The Metals Translator: Guidance for Calculating a Total Recoverable
Permit Limit from a Dissolved Criterion (EPA 823-B-96-007, June 1996) and the
equation:
Cdiss =
Ctotal
1
1 + { [xi.] [sso +a)] [ 10 6]
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used,
and
Kpo and a = constants that express the equilibrium relationship between dissolved
and adsorbed forms of metals. A list of constants used for each hardness -dependent
metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient (or
site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca = (s7Q 10 + Ow) (Cwqs) — (s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw = permitted effluent flow (cfs, match s7Q10)
Page 14 of 15

s7Q10 = summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q10 may be incorporated as applicable:
1 Q 10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of water,
fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations, the discharge is considered to show
reasonable potential to violate the water quality standard, and a permit limit (Total allowable
concentration) is included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on
40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium data
results may be used as a conservative surrogate in cases where there are no analytical results
based on chromium III or VI. In these cases, the projected maximum concentration (95th %) for
total chromium will be compared against water quality standards for chromium III and
chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit included:

NC0041696 3.5 MGD RPA 112.5 CFS, rpa
11/9/2017

First of all, thank you for the time and effort the State has put into writing the draft permit for the Town of
Valdese.
While the Town is in agreement with most of the changes proposed for the new permit, there are a few
areas of contention and at least one perceived error in wording.
The seventh (7th) bullet point on the draft proposal states, `added monthly and daily maximum effluent
limits for ammonia nitrogen for the permitted flow of 7.5 MGD as per NPDES Permitting Guidance to
implement ammonia chronic criteria. (See A. (2))'
The "daily" does not match up with the Effluent limitations and monitoring requirements page. Should
this read monthly and weekly average, not daily maximum?
Regardless of the language of the ammonia nitrogen requirements, the Town does not agree with the
increased monitoring of NH-3 on the 3.5 MGD permit, previous sampling does not support this increased
monitoring. The average discharge for NH-3 for each of the past 4 years has been <.50, with only 2
samples out of 205 being >= 2.0 mg/I. A total of 184 samples resulted in a zero (0) or less than detection.
The Town further opposes the increased monitoring and included limits on the 7.5 MGD permit based on
the past results. The Town feels the changes in NH-3 monitoring for the 3.5 and 7.5 MGD permit are
unwarranted. The Town requests that NH-3 remain the same as the current permit, monitor weekly on the
3.5 and 7.5 MGD or be removed altogether.
The Town request, as has been requested in the past, that the upstream and downstream monitoring
requirement be totally removed from the permit. The data, that is collected by the Town, from upstream
and downstream monitoring has no scientific value. The current permit allows for sampling once per
week during the summer months and once per month during the remaining months of the year. The Town
has seen no variability in the data over the years. Data collected has not been useful in modeling any
changes to the lake over the years. The Town feels that the upstream and downstream sampling is a gross
miss use of time and resources, both for the Town and anyone that reviews the data. And as such should
be removed from the permit requirements.
The Town would also like to go on record as opposing the usefulness of the Mercury Minimization Plan
(MMP). The issue of mercury in the streams was not created by the wastewater plants, but the wastewater
plants are being made to bear a great deal of the cost and responsibility in an attempt to remove mercury
and clean up the waters of the state, when most mercury is a result of discharge of mercury into the
atmosphere. That being said, the Town will comply and have a MMP in place within 180 days permit
effective date.
Thank you,

Dear Mr. Padgett,

The Division has received a request from EPA to provide information on Lake Rhodhiss WWTP's outfall configuration.
The drawings submitted with the NPDES permit renewal application are not clear. They would like to know if the outfall
is a single pipe or multiple pipes, how far is the outfall from shore. Is there an aerator or diffuser at the outfall? Can
you provide a better scanned copy of the drawing showing outfall and lake Rhodhiss? Please email me your response by -
Thursday, 11/9/2017.
Thanks.

Hi Trupti,
Thank you for getting us this draft permit before sending it out.
My thoughts on this have to do with the U/D sampling. First of all, I wanted to make sure you knew that their discharge
pipe is extended into the lake, their upstream sample location is —0.84 miles upstream at the water treatment facility
and their downstream location is —1.1 miles downstream at the bridge. The U/D samples are taken from the
shoreline/bank, otherwise they would need a boat. Also, in between their WW discharge and their upstream sampling
location a creek (McGalliard Creek) flows into the lake. I attached a snapshot for your reference.
I am all about instream data, so my first comment is we should add pH to the parameters for U/D. They are going to get
pH anyhow since they will use a multimeter and it is an important parameter for this lake. My next would be they may
push back on this monitoring and the frequency; questioning the relevance. I am not sure how U/D sampling with lake
discharges is justified, but heads up they will ask I am curious too.
Another thought is they will do their upstream hardness at the water treatment facility. McGalliard Crk will not be
represented. Not sure if that is a concern or not.
Thanks,

History/2010 Renewals. For the 4 WWTPs listed above that discharge to Lake Rhodhiss in the Catawba River Basin,
NPDES added additional effluent and instream nutrient monitoring requirements for the 2010 renewals to support
future TMDL efforts. At the time, the receiving waterbody was listed as impaired for pH (believed due to excessive algal
production) but not for chl-a.
Permitting Strategy/2015 Renewals. Lake Rhodhiss is no longer listed as an impaired waterbody on the 2014 303(d) list
and there is no plan for TMDL development. Therefore, for 2015 renewals, please make the following changes to these
permits:
• Effluent Monitoring for Nutrients (TN/TP). Change monitoring frequency from Weekly to Monthly, which will be
consistent with 15A NCAC 2B.0508 requirements.
• Instream Monitoring for Nutrients (TN/TP). Delete this Monthly requirement (Note: I don't think the
requirement was established for Valdese, which discharges directly to the lake).
• Fact Sheet. You can state in the Fact Sheet that the basis for these changes is due to the removal of Lake
Rhodhiss from the 2014 303(d) impaired waters list.
This permitting decision was made in consultation with the Modeling Unit/Pam Behm. I'll place E copy of this email in
each permit file. Let me know if any questions.

Subject: RE: Lake Rhodhiss NPDES question
Hi Trupti,
So after some digging through Duke's FERC license documents, I think I have found what you are looking for. I think. As
you know the Town of Valdese discharges directly into Lake Rhodhiss which is covered under Duke's RC license
agreement. According to this agreement, the year-round minimum average daily flows are set then the
basin goes into any stage of drought, there is a low inflow protocol that then dictates what that required release must
be. That is based on several different variables listed in the LIP document.
The water quality in Lake Rhodhiss has relatively high nutrient levels and it has been recommended in the last Basin Plan
to add nutrient monitoring to the WWTP permits (see page 4.14 of this chapter). I'm not sure if that was included
during the last renewal cycle but if not could provide more information if needed to include it during this cycle.
Please let me know if you have any questions or if you all would like a presentation about water quality in the Catawba
since the last plan was developed. I know we had a semi kick off meeting a while back but due to the late notice, I was
not able to provide you all with much analysis.
I hope this helps and please feel free to reach out any time.
Thanks,
Melanie

Melanie,
I thought that you might be on a vacation when I did not get the reply. But yes, I am still counting on this
information. Previous permit was issued using same dam release data for 7Q10 winter and summer. Just want to
confirm before moving further with this permit. Your input will be greatly appreciated.
Thanks.

Trupti,
So sorry for the delay in my response. I was on vacation here and there since the 30th and am still trying to catch up on
my email. Are you still looking for this information? I will start looking into it unless I hear otherwise. I'm not certain off
the top of my head what the release is but the dam is covered under Duke's FERC license. Will check their license
agreement to see what is stated there and will check with Duke to see if they have any info that could help.
Thanks,
Melanie

Subject: Lake Rhodhiss NPDES question
Hi Melanie,
I am currently working on NPDES permit NC0041696 for the Town of Valdese in the Catawba River Basin. I would like to
know if the Lake Rhodhiss dam releases on a set schedule, or on an intermittent basis? The only 70.10 data we have is
for the summer months, based on dam releases. Any operational info you have would be a great help.
Thanks.

Dear Mr. Bortnick,
Governor
DONALD R. VAN DER VAART

S. JAY ZIMMERMAN
Director
As you may know, in 2012 North Carolina adopted an EPA approved statewide mercury total
maximum daily load (TMDL). To demonstrate compliance with the TMDL Permittees must be
able to quantify the amount of mercury being discharged from point sources to the lower
reporting level of the procedure.
In order to gather the appropriate data, all effluent mercury analysis must be conducted using
the low level Method 1631 E. This could be accomplished through the NPDES permit as a
monitoring requirement, but that may require more frequent sampling than what is required by
the Pretreatment monitoring plan. Therefore, if you are not already doing so, please beginning
as soon as possible any effluent analysis for mercury must be done using EPA test Method 1631
E. You do not have to update your monitoring plan at this time; a copy of this letter in the file
will document this requirement.
Thank you for your continued cooperation with the Pretreatment Program. If you have any
questions please contact me at [phone] or via email [[e-mail]].
Sincerely,
Likwk,J, ).40/t-Q
