Re: Comments for Draft Permit NC0026123 Permitting Section
Dear Mr. Perlmutter:
Thank you for your work in preparation of the above referenced permit. City of Asheboro
Wastewater Treatment personnel have some questions and concerns regarding monitored
contaminants and limits listed in the draft permit. Asheboro would like some modifications to the
draft permit before final issuance. The following notes and requests should be considered before
issuing the final NPDES permit.
The WWTP staff requested mass based limits for ammonia in lieu of concentration based limits
during the March 29, 2018 meeting at the WWTP. 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.
Chloride has consistently been sampled in conjunction with Toxicity testing in previous permit
cycles. Asheboro has never failed toxicity based on the chloride 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.
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 the
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<0.01mg/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.
Asheboro Staff is actively exploring alternatives in how to meet the new bromodichloromethane
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 and environment.
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 for 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.
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 manufacturingprocess as well as toxic review inventorysubmitted annuallyto EPA.
This industry is only requiredto 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.
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 but also DEQ.
Please carefully consider all of the above comments before issuing a final permit. Written
clarification on all questions posed in this correspondence is requested. I will be glad to discuss
any of these concerns with you and appreciate your prompt and thorough response to this matter.
Respectfully,

Subject: Draft NPDES Permit Renewal
Permit NC0003719
DAK Americas WWTP
Cumberland County
Class 2 Facility
Dear Mr. Hendrickson:
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. The draft permit public noticed on October 31,2017 included TSS limits based on ELGs
and BPJ. The BPJ limits for BOD and TSS applicable to Clear Path Recycling were calculated
using 95%reduction within the treatment system. The Division acknowledges that this approach
was erroneous for calculating TSS limits and recalculated the TSS limits based on 85%reduction.
Since the TSS limits are less stringent than in the previous draft permit a second public notice is
needed.The draft permit includes the following changes from your previous permit:
• Limits for BOD, TSS and toxic pollutants for Outfall 002 were modified based on the
effluent guidance limits and the updated production flows for DAK Americas and Clear
Path Recycling.
• Requirements for Outfall 001 were modified to reflect typical cooling water monitoring
requirements. Although this is a combined outfall discharging cooling water and
stormwater it is considered a wastewater outfall for permitting purposes.
• Annual monitoring for mercury was added at outfall 002 in accordance with the
implementation of the 2012 Statewide Mercury TMDL.
Annual monitoring for 1,4 Dioxane was added at outfall 002. 1,4 Dioxane is a pollutant
of concern in the Cape Fear River. The Division is implementing monitoring to gather
data on this pollutant.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted
Stale of North Carolina Environmental Quality I Water Resources
1617 Mail Service Center I Raleigh,North Carolina 27699.1617
919 807 6300

Page 12
and became effective on December 21,2015.The requirement to begin reporting
discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report(eDMR) internet application has been added to your final NPDES
permit. [See Special Condition A.(7)]
For information on eDMR,registering for eDMR and obtaining an eDMR user account,
please visit the following web page: http://deq.nc.gov/about/divisionslwater-

• The NPDES Standard conditions(Parts II,Ill,and IV)are not included with this draft.
They can be found at the following link to review them in conjunction with this draft
permit:https://deq.nc.gov/permitting-forms.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Cumberland County area,soliciting public comments on this draft
permit. Please provide any written comments you may have to the following: NCDEQ/DWR,
NPDES Permitting Branch, 1617 Mail Service Center,Raleigh,NC 27699-1617 no later than 30
days after receipt of this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments
and take appropriate action prior to issuing a final permit. If you have questions concerning this
draft permit,please call me at(919)807-6387or by email at [e-mail].

A. (4.) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT(QUARTERLY) [15A NCAC 02B
.0200 et seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled"Pass/Fail Methodology For Determining Acute Toxicity In A
Single Effluent Concentration"(Revised December 2010 or subsequent versions). The monitoring shall
be performed as a Fathead Minnow(Pimephales promelas)24-hour static test.The effluent
concentration at which there may be at no time significant acute mortality is 90%(defined as treatment
two in the procedure document). The tests will be performed during the months of February,May,
August,and November. 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.
Should any single quarterly monitoring indicate a failure to meet specified limits,then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing,this
monthly test requirement will revert to quarterly in the months specified above.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form(MR-1) for the month in which it was performed,using the parameter code
TGE6C. Additionally, DWR Form AT-2(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,North Carolina 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.
Page 6 of 11

NC0003719
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required,the permittee will complete the information located at the top of the aquatic toxicity(AT)test
form indicating the facility name,permit number,pipe number,county, and the month/year of the report
with the notation of"No Flow"in the comment area of the form.The report shall be submitted to the
Water Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately until such time that a single test is passed.Upon passing,
this monthly test requirement will revert to quarterly in the months specified above. 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 either these monitoring requirements 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 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.) BIOCIDE APPROVAL [G.S. 143-215, 143-215.1]
The Permittee shall obtain approval from the Division's Aquatic Toxicology Unit prior to discharging any biocide
(not previously approved by the Division)under this permit. Approval for use of any biocide not previously The
Permittee shall request approval of any new unauthorized biocide at least 90 days in advance of planned usage.
Contact the Aquatic Toxicology Unit for detailed instructions on requesting biocide approval:

Raleigh,North Carolina 27699-1621
A. (6.) LABORATORY TEST-METHOD QUANTITATION LEVELS AND COMPLIANCE
[G.S. 143-215.66]
For any given parameter,the Permittee must apply a state-certified analytical test method with a practical
quantitation level(PQL)at or below the NPDES permit limit. If such level of analytical sensitivity is not
technologically feasible,the Permittee shall employ a state-certified analytical method with the lowest available
test-method PQL,and values reported as"not detected"by this lowest available PQL shall be deemed
"compliant"with this permit.

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.)(a)(
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report(eDMR)internet application.
Monitoring results obtained during the previous month(s)shall be summarized for each month and submitted
electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and
submit DMRs electronically using the internet. Until such time that the state's eDMR application is
compliant with EPA's Cross-Media Electronic Reporting Regulation(CROMERR),permittees will be
required to submit all discharge monitoring data to the state electronically using eDMR and will be required
to complete the eDMR submission by printing,signing,and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access,then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forms(MR 1, 1.1,2,3)or alternative forms approved by
the Director. Duplicate signed copies shall be submitted to the mailing address above. Sec"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).

NC0003719
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:
htth://www2.e; a. ov/com liance/final-national- ollutant-dischar e-elimination-s‘stern-n.'des-electronie-
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:
htt ://de .nc.iov/about/divisions/water-resources/edmr
4. Si_nator' Requirements 'Supplements Section B. 014 (b)and Supersedes Section B.(11.) (d)!
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 Il,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:
