Subject: Draft NPDES Permit Renewal
Permit NC0020559
Henderson WRF
Vance County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Frazier:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
• Facility component list on the Supplement to Permit Cover Sheet has been updated per
receipt of Engineer's Certificate to include two new WAS pumps, a screw thickener, and
a screw thickener discharge pump. Based on the Compliance Evaluation Inspection Letter
dated February 13, 2019 from Raleigh Regional Office staff, the facility component list
was updated to remove primary clarifiers, trickling filters, secondary clarifiers, pure
oxygen activated sludge nitrification basin, anaerobic digesters, and sludge drying beds,
and to add the biological nutrient removal system.
• Effluent sampling data for Zinc did not show reasonable potential to violate Water Quality
Standards, therefore, quarterly effluent monitoring for Zinc has been removed from the
permit [See A. (1) and A. (2)].
• Effluent sampling data for Copper showed reasonable potential to violate Water Quality
Standards. Monthly monitoring and limitations for Copper were added to the permit [See
A. (1) and A. (2)].
• The City of Henderson has reported Total Cadmium, Total Silver, and Total Selenium at
less than detection in the three Effluent Pollutant Scans and effluent data; reporting < 2
µg/L for Total Cadmium, < 5 µg/L for Total Silver, and < 10 µg/L for Total Selenium. In
accordance with 15A NCAC 2B .0500 all test procedures must produce minimum detection
and reporting levels that are below the allowable discharge concentration of a parameter
and all data generated must be reported down to the minimum detection or lower reporting
level of the procedure. DWR's lab has recognized that the target Practical Quantification

Limit (PQL) for Total Cadmium is 0.50 µg/L, and the PQL for Total Silver and Total
Selenium is 1.0 µg/L. The City's allowable discharge concentration for Total Cadmium is
1.738 µg/L,Total Silver is 0.062 µg/L,and Total Selenium is 5.2 µg/L.Therefore,quarterly
monitoring for these parameters has been added to the permit, and the City is expected to
use sufficiently sensitive test methods when analyzing effluent data. [See A. (1) and A.
(2)].
• DWR's lab has recognized that the target PQL for Cadmium is 0.50 µg/L, Lead is 2.0 µg/L,
and Arsenic is 2.0 µg/L. No monitoring has been added to the permit for these parameters,
however, the City is expected to use sufficiently sensitive test methods when analyzing
effluent data. For reference, DWR's most up-to-date list of target PQLs can be accessed
online: https://deq.nc.gov/about/divisions/water-resources/water-resources-data/water-
sciences-home-page/microbiology-inorganics-branch/methods-pqls-qa
• Limits for ammonia-nitrogen have been changed for expansion flow of 6.0 MGD based on
North Carolina's implementation of EPA's ammonia-nitrogen criteria in developing
toxicity-based NH3-N allocations protective of North Carolina streams [See A. (2)].
• Effluent mercury data was reviewed from January 2015 to April 2018. In accordance with
the NPDES Permitting and Mercury Implementation Strategy approved in conjunction
with the 2012 Mercury TMDL, the permittee needs to show annual average effluent
concentrations below the Water Quality Based Effluent Limitation (WQBEL) and the
individual mercury sample results below the Technology Based Effluent Limitation
(TBEL). Review of the data showed that both criteria were met for both 4.14 and 6.0 MGD
flows. Therefore, mercury limitations and monitoring requirements have been removed
from the Effluent Limitations and Monitoring Requirements [See A. (1) and A. (2)].
However, monitoring for mercury using the low-level test method 1631 E shall continue
when performing the three effluent pollutant scans [See A. (5)].
• The Mercury TMDL emphasizes Mercury Minimization Plans (MMPs) for point source
control. The NPDES Permitting and Mercury Implementation Strategy requires municipal
facilities>2.0 MGD and discharging quantifiable levels of mercury(> 1.0 ng/L)to receive
a MMP requirement. Based on the review of mercury effluent data, a MMP Special
Condition was added to the permit [See A. (6)].
• Upstream and effluent quarterly monitoring for total hardness has been added to the permit
for all flow tiers (4.14 and 6.0 MGD) as required by the implementation guidance for the
new dissolved metal standards [See A. (1), A. (2), and A. (3)].
• Some of the wording has changed in Special Condition A. (4), Chronic Toxicity Permit
Limit; please review each paragraph carefully.
• Special Condition A. (5) has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed (2020, 2021, 2022). In addition, at the end of
the Special Condition, 2nd Species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21 (j)(5)] have been added.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)
internet application has been added to your NPDES permit [See Special Condition A. (7)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[See A. (1) and A. (2)].
• Regulatory citations have been added to the permit.

above the confluence of Indian Creek and Crooked Creek.
2. Profiles should be taken at one (1) meter intervals.
3. Composites shall be collected as spatial composites throughout the photic zone (i.e. two times
the secchi depth.)
As per 15A NCAC 2B.0505(c)(4), stream sampling may be discontinued at such time as flow
conditions in the receiving waters or extreme weather conditions will result in a substantial risk of
injury or death to persons collecting samples. In such cases, on each day that sampling is
discontinued, written justification for the discontinuance shall be specified in the monitoring report
for the month in which the event occurred. This provision shall be strictly construed and may not
be utilized to avoid the requirements of 15A NCAC 2B.0500 when performance of these
requirements is attainable. When there is discontinuance pursuant to this provision, stream
sampling shall be resumed at the first opportunity after the risk period has ceased.
A. (4) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 026.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90% for 4.14 and 6.0 MGD flows.
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.

Permit NC0020559
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.
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) EFFLUENT POLLUTANT SCAN (Municipal POTWs) [G.S. 143-215.1(b)]
The permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below.
One scan must be performed in each of the following years: 2020, 2021, and 2022. Analytical methods
shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether
parameters are present in concentrations greater than applicable standards and criteria. Samples
should be collected with one quarterly toxicity test each year, and must represent seasonal variation
[i.e., do not sample in the same quarter every year]. Unless otherwise indicated, metals shall be
analyzed as "total recoverable."

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). The US EPA requires four (4) toxicity tests for a test organism other than the test
species currently required in this permit. The multiple 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. These tests
shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple
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. (6) 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 within 180 days of the NPDES Permit Effective Date, 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
(https://deq.nc.gov/document/nc-model-mercury-minimization-plan-dwr-npdes-swp-20130801).
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. (7) 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. The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of
this permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements (Supersedes Section D. (2.) and Section E. (5.) ()J
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
Page 10 of 13
Permit NC0020559
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above. See "How to Request a Waiver from Electronic
Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following
the commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify
the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated
entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
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.
