Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Rhoney:
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. As the last draft permit was submitted for public comment in May 2018, changes
highlighted below are compared to the existing active permit, and not the previously submitted
draft permit. However, responses to comments submitted regarding the May 2018 draft permit
have been attached. There are several changes from the existing permit, including the following:
• Per the results of instream waste concentration (IWC)-based calculations for ammonia -
nitrogen, ammonia nitrogen limits have been revised [See A.(1.)].
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the limits and monitoring requirements for total chromium
and total zinc have been removed from the permit [See A.(1)].
• Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD5, NH3-N,
Total Suspended Solids and Enterococci have been reduced to twice per week [See A.(1.)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total silver, bromodichloromethane, and 1,4-Dioxane limits and
monitoring requirements have been added to the permit [See A.(1)].
• Based on the reasonable potential analysis (RPA) predicting a maximum effluent total
selenium concentration that is greater than half of the allowable discharge concentration
based on state water quality standards, quarterly monitoring for total selenium has been
added to the permit [See A.(1)].
• To provide an opportunity for the City to develop a plan to assess sources of total silver in
order to come in compliance with the limits in Section A.(1.), a schedule of compliance has
been added to the permit [See Special Condition A.(4.)].

• To provide an opportunity for the City and their industries to develop a plan to assess
sources of and implement technology to control discharges of 1,4-Dioxane in order to come in
compliance with the limits in Section A.(1.), a 5-year phased schedule of compliance has been
added to the permit [See Special Condition A.(6.) Schedule of Compliance for 1,4-Dioxane
Limitations].
• Based on resulting patterns indicating effluent impact on the receiving waterbodies and to
assess background concentrations of 1,4-dioxane to better analyze the discharge, instream
monitoring for 1,4-Dioxane has been added to the permit [See A.(1.)]. The Permittees'
instream sampling requirement for this parameter is provisionally waived as long as the
Permittee is a member of the UCFRBA and the nearest upstream and downstream monitoring
coalition stations are being monitored for 1,4-dioxane at a frequency of at least Monthly.
• A special condition to monitor effluent PFAS chemicals quarterly has been added to the
permit, to be effective six (6) months after EPA has a final wastewater method in 40 CFR136
method published in the Federal Register [See Special Condition A.(8.) PFAS Monitoring
Requirements].
• Based on the Mercury TMDL evaluation showing no annual average mercury
concentration exceeded the WQBEL, and no individual mercury sample exceeded the TBEL,
the limits and monitoring requirement for total mercury have been removed from the permit
[See A.(1)].
• Based on Mercury TMDL evaluation showing mercury values reported at levels > 1 ng/L
and since the permitted flow is greater than 2 MGD, Special Condition A.(7.) Mercury
Minimization Plan (MMP) has been added to the permit.
• Based on review of instream data, instream conductivity, TN, TKN, NO2+NO3,
ammonia, and TP monitoring has been added to the permit [See A.(1.)]. The Permittees'
instream sampling requirements for these parameters are provisionally waived as long as the
Permittee is a member of the Upper Cape Fear River Basin Association (UCFRBA).
• The Division is implementing dissolved metals standards in all permits, per the 2016
revisions to State water quality standards. As such, the NPDES Permitting Unit will need
site -specific effluent hardness data for each facility monitoring these metals in order to
calculate permit limitations. Effluent hardness sampling has been added to the permit at a
monitoring frequency of quarterly [See A.(1.)].
• Some of the wording has changed in Special Condition A.(2.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A.(3.) has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed (2024, 2025, and 2026). 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.
• A notation was made concerning the Electronic Reporting Rule — NPDES Electronic
Reporting Rule — Phase 2 Extension. EPA extended the Phase 2 deadline to December 21,
2025.
• 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.(10.)].

Asheboro WWTP (NC0026123) Public Comments and Responses
Comments to the draft Asheboro WWTP NPDES permit (NC0026123) were received from the City of
Asheboro, dated 5/31/2018. Comments and responses are below:
• Comment: "The WWTP staff requested mass based limits for ammonia in lieu of concentration
based limits during the March 29, 2018 meeting at the WWTP [site visit]. Upon review of
historical data, mass based limits are attainable. What was the rationale for not using mass
based limits in the draft permit? Asheboro is requesting a three year compliance schedule to
research alternative treatment options that will allow for consistent compliance if mass based
limits are not allowed."
Response: Concentration -based limits are in the permit because EPA water quality criteria for
ammonia (i.e., 1.0 mg/L summer, 1.8 mg/L winter) are expressed as concentrations, not mass, and
are based on concentration -based toxicity studies. An updated review of effluent data shows that
the Asheboro WWTP has not reported a weekly average or monthly average ammonia
concentration that is greater than the proposed limits since January 2018. As the facility is
consistently meeting the proposed limitations, a compliance schedule does not appear necessary
and has not been added to the permit.
• Comment: "Chloride has consistently been sampled in conjunction with Toxicity testing in
previous permit cycles. Asheboro has never failed toxicity based on the chronic results and has
had an excellent track record for passing toxicity testing. Explain what factors, data and
calculations the Reasonable Potential Analysis are based on and confirm how this number is
obtained."
Response: The RPA was conducted on 15 sample concentrations ranging from 68 to 300 mg/L,
collected from March 2014 — December 2017. The RPA results showed that the chloride standard
of 230 mg/L could be violated with a maximum predicted value of 351 mg/L. However, since
Asheboro is passing toxicity tests, only monitoring is required. This is consistent with 15A
NCAC 02B .0211 (22): If chloride is determined by the waste load allocation to be exceeded in a
receiving water by a discharge under the specified 7Q10 criterion for toxic substances, the
discharger shall monitor the chemical or biological effects of the discharge - Monitoring will be
maintained in conjunction with toxicity tests. Asheboro should use this permit cycle as an
opportunity to assess sources of chloride and how it can reduce this pollutant so that the allowable
discharge concentration can be achieved in the next permit cycle.
• Comment: "Staff reviewed historical influent and effluent data for Cyanide collected since 2010.
During this time no samples ever resulted in above detect for the influent. However, a period of
seven days in September of 2015, three effluent samples resulted in a detection of cyanide. Upon
review of the lab bench sheets, the data indicates that there was an interference with the test
method in these samples and therefore these data points should have not been used or reported. A
copy of relevant bench sheets are attached with this correspondence. All samples collected from
March 2, 2010 to June 4, 2015 and after September 22, 2015 have been recorded as non -detects
<0.01 mg/L (one was <0.005mg/L). The maximum data point used to show reasonable potential
for cyanide should not be considered in light of this interference as it is not an accurate reflection
of Asheboro WWTP effluent. Asheboro requests the limit and monitoring requirements for
cyanide be removed."
Response: A Reasonable Potential Analysis review has been conducted based on the last 4.5
years of effluent data (March 2018 — June 2022). Based on the reasonable potential analysis
(RPA) showing no reasonable potential to violate state water quality standards, total cyanide
limits and monitoring requirements have not been added to the permit.

Asheboro WWTP (NC0026123) Public Comments and Responses
• Comment: `Asheboro Staff is actively exploring alternatives in how to meet the new
boromodichloromethane limit. We would like to request a two year compliance schedule to
evaluate our disinfection process and determine how to effectively reduce our
bromodichloromethane concentrations but continue to properly disinfect the wastewater in order
to continue to protect the stream end environment."
Response: The City informed the Division via email notification on 11/29/2022 that a
bromodichloromethane compliance schedule is no longer requested.
• Comment: `Asheboro staff is aware of the concern associated with 1,4 dioxane and will be able
to comply with the terms of the three year compliance schedule. However, Asheboro is not
inclined to regulate an industry that may be discharging 1,4 dioxane based on the inconclusive
data regarding the health effects of this parameter and the lack of enforceable stream standards.
We feel identifying the sources of this contaminant is crucial. However, any sources found should
have ample opportunity to provide options of reducing or eliminating the contaminant while
properly budgeting funds which are anticipated to be substantial. Asheboro believes after the
sources are identified, then a set of standards should be developed and limits applied. Staff would
like an explanation of the legal basis and calculations for the 149 ,ug/L limit in this draft permit."
Response:
Division regulations applicable to 1,4-Dioxane limitations:
• 15A NCAC 02B .0206(a)(4)(B) identifies that for the flow design criteria for effluent limitations,
the average annual flow for toxic substances shall be used to protect human health.
• 15A NCAC 02B .0208(a)(2)(B) identifies for carcinogens, an unacceptable exposed risk level is
1 x 10-6 or greater.
• 15A NCAC 02B .0216(4)(d) Fresh Surface Water Quality Standards for Class WS-IV Waters
identifies that no discharge of sewage "...shall be allowed that have an adverse effect on human
health or that are not treated in accordance with the permit or other requirements established by
the Division..."
The previously identified allowable discharge concentration of 149 µg/L for 1,4-Dioxane was
based on a Reasonable Potential Analysis for the human health criterion of 80 µg/L in non -water
supply waters. The non-WS criterion was based on a calculated 1 in 1,000,000 cancer risk from
fish consumption per 15A NCAC 02B .0208.
1,4-dioxane is completely miscible in water and resistant to biodegradation. It is assumed that
concentrations of 1,4-dioxane discharged from the WWTP will be equivalent at the direct
discharge to Hasketts Creek, a class C waterbody, and the nearest downstream water supply (WS-
V) boundary, located in the Deep River 1.0 mile upstream of Tysons Creek and 43.5 miles
downstream of the outfall. As such, in this reevaluation, allowable discharge concentrations were
calculated for both the direct discharge to Class C Hasketts Creek and for the nearest downstream
water supply (WS-V) boundary, and the more restrictive concentration was selected for
protection of downstream uses. The water supply boundary is for the Deep River (Gulf-
Goldston) water supply watershed, whose water supply intake is currently inactive. Each
allowable discharge concentration was calculated considering the applicable receiving stream's
Average Annual Flow (AAF), appropriate Instream Target Value (ITV) and the facility's
permitted design flow.
Page 2 of 4

Asheboro WWTP (NC0026123) Public Comments and Responses
For the direct discharge to Class C Hasketts Creek, an ITV of 80 µg/L for non -water supply
waters at an AAF of 12 cfs and a permitted design flow of 9.0 MGD (13.95 cfs) was considered.
This calculation yielded a chronic allowable discharge concentration of 149 µg/L. When
considering the downstream WS-V waters, a 1 x 10-6 risk level ITV of 0.35 µg/L for water supply
waters at an AAF of 846 cfs (calculation estimated by USGS for WS-V boundary of Gulf-
Goldston WS watershed) and a permitted design flow of 9.0 MGD (13.95 cfs) was considered.
This calculation yielded a chronic allowable concentration of 21.58 µg/L. The allowable
discharge determination based on direct discharge to Class C Hasketts Creek is insufficiently
protective of downstream water supply uses. As such, the chronic allowable discharge
concentration of 21.58 µg/L has been used in determination of permitting actions.
Based on a review of the effluent data, the WWTP demonstrates a reasonable potential to exceed
both the EPA drinking water heath advisory (HAL) of 35 µg/L and the state water supply
Instream Target Value (WS ITV) of 0.35 µg/L for 1,4-Dioxane at the nearest downstream water
supply boundary. As the reported effluent concentrations of 1,4-dioxane are greater than 35 µg/L,
the facility discharges to non-WS waters with downstream WS waters, and reasonable potential to
exceed applicable ITV at downstream WS boundary has been demonstrated. As such, weekly
monitoring and limits have been added to the permit. Recognizing that 1,4-Dioxane is an
emerging contaminant and industrial users are just now understanding its impact and use in
materials, a phased implementation compliance schedule has been included in the permit. Please
see the fact sheet for additional information regarding 1,4-dioxane permitting actions.
• Comment: "Staff has discovered a NPDES permit issued to DAK Americas (permit # NC0003719
— included with this correspondence) dated March 20, 2018 in the Cape Fear River Basin —
direct discharge to the Cape Fear River. This industry has the potential to be a significant
discharger of 1,4 dioxane based on their manufacturing process as well as toxic review inventory
submitted annually to EPA. This industry is only required to monitor annually and report
according to the newly issued permit. This appears to be a discrepancy and Asheboro staff does
not understand the difference in permit requirements Staff feels if we are held to this standard
then it should be included in the reasonable potential analysis for all state issued permits and all
permit holders should be held to the same set of standards."
Response: The DAK Americas permit has a monitoring only requirement for 1,4-Dioxane to
determine whether this facility discharges the contaminant in detectible amounts, given the
concern of 1,4-dioxane in the Cape Fear River basin as a whole. The only historical 1,4-Dioxane
data generated by the facility was in 2003, well before the implementation of EPA Test Method
164.1 in 2017, and under a process that has since changed. Asheboro has generated sufficient data
to perform an RPA.
• Comment: "Staff would like an explanation as to why the term for this permit is only four years.
NPDES permits are typically written for 5 year terms. It is understood that we have been
operating on an expired permit for some time but shortening the term of the new permit to four
years is a burden not only for city personnel bur also DEQ."
Response: The permit term has been revised to be 5 years.

Asheboro WWTP (NC0026123) Public Comments and Responses
Comments were received from Mick Noland (Fayetteville Public Works Commission, PWC), Jim
Fletchner (Cape Fear Public Utility Authority, CFPUA, Wilmington), Victor Czar (City of Sanford), and
Jeff Adkins (Town of Cary) via e-mail on June 8, 2018. All commenters represent municipalities with
water supply concerns of 1,4-Dioxane. Comments are summarized as follows:
• All commenters ask the Division to consider the designated uses of the river downstream in 1,4-
Dioxane limit development.
• PWC, CFPUA and Sanford representatives request that other sources of 1,4-Dioxane be
considered in developing limits.
• CFPUA cites the EPA health advisory for 1 in 10,000 cancer risk of 35 µg/L in drinking water.
• Sanford cites the water supply criterion of 0.35 µg/L and requests DEQ conduct an analysis to
determine if the 149 µg/L limit is protective of the 0.35 µg/L criterion at the WS-IV classified
water downstream at the confluence of Governors Creek with the Deep River.
• CFPUA requests the compliance schedule be reduced; PWC and Sanford request a 2 yr
compliance schedule
• PWC requests a public hearing
• PWC will consider legal action should DWR not consider downstream WS and other sources in
limits development
Response: Please see the response to the City of Asheboro's above comment and the revised Other
WQBEL Considerations section of the fact sheet, with pages 16 and 17 focusing on the 1,4-dioxane
compliance schedule for more information.

A.(2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200] [15A NCAC 02B .0500 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 90%.
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 March, June, September, and
December. 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 electronically using the
Division's eDMR system 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:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email, [e-mail].
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.

1. Reporting Requirements ISupersedes 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
monthly electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data
and submit DMRs electronically using the internet. The eDMR system may be accessed at:
https://deq.nc.gov/about/divisions/water-resources/edmr.
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 following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Monitoring results obtained during the previous month(s) shall be summarized for each month and reported
via the eDMR system no later than the last calendar day of the month following the completed reporting
period. 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, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports; and
• 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. federalregi ster. gov/documents/2015/ 10/22/2015 -24954/national-pollutant-discharge-elimination-

Permit NC0026123
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
