Mr. John Condrey
NC0074306 Issued Permit
The fmal permit includes the following significant changes from the draft permit:
1. The footnote for upstream hardness sampling was modified to indicate sampling should occur
only if flow is available.
2. A new Section A. (3)has been added to address the existing Discharge Monitoring Reporting
waiver should a discharge be needed.
The NC 2007-2014 Water Quality Standard(WQS) Triennial Review was approved by the NC
Environmental Management Committee(EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water
Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in all
permits public noticed after April 6, 2016.
The new standards for most metals include acute standards. Further, the freshwater standards for several
metals are expressed as the dissolved form of the metals, and seven metals have hardness-dependent
equations. As a result,the NPDES Permitting Unit will need site-specific effluent hardness data and
instream hardness data,upstream of the discharge, for each facility monitoring these metals in order to
calculate permit limitations. Effluent hardness and instream hardness sampling,upstream of the
discharge, has been added to this permit at a monitoring frequency of quarterly. See Section A.(1.)
Effluent Limitations and Monitoring Requirements.
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 permit 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 any other Federal, State, or Local governmental permit that may be required.
If you have any questions or need additional information,please do not hesitate to contact Brianna
Young of my staff at(919) 707-3619.

Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system[see Section A. (4)].
2. Duration of discharge should be noted in log books and a Total daily discharge reported in the DMR.
3. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the
permit.However,the Permittee shall continue to record and submit all values reported by a North Carolina
certified laboratory(including field certified),even if these values fall below 50 µg/L.
4. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals
(cadmium,copper,lead,nickel, silver, and zinc).
5. The Permittee shall sample instream hardness,upstream of the facility's discharge if flow is available.The
sample shall be representative of the hardness in the receiving stream. If the Permittee is a member of the
Monitoring Coalition Program, sampling for instream hardness may be waived as long as the Monitoring
coalition agrees to sample hardness at the nearest upstream location,at a minimum frequency of quarterly,
Page 3 of 8

Permit NC0074306
and the Permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being
monitored by the Coalition is representative of the receiving stream for this discharge. The Permittee is
responsible for submitting instream hardness test results with its permit renewal application package. If
Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the approved
station,the Permittee will immediately notify the Division and resume sampling for instream hardness,
upstream of its discharge.
6. Toxicity testing should be performed using Ceriodaphnia dubia 48 hour acute pass/fail test @ 90%
concentration during the months of January,April,July, and October. [See Section A. (2)].
All samples must be collected from a typical discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
Page 4 of 8

Permit NC0074306
A. (2) ACUTE TOXICITY PASS/FAIL MONITORING(QUARTERLY)
[15A NCAC 02B .0500 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 Ceriodaphnia dubia 48 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).
Effluent samples for self-monitoring purposes must be obtained during representative effluent discharge
below all waste treatment. 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.
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
TGA3B. Additionally, DWQ Form AT-2 (original)is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response 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
Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test
requirement will revert to quarterly in the months specified above. 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 Quality indicate potential impacts to the receiving stream,this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
Page 5 of 8

Permit NC0074306
Should it be determined by the North Carolina Division of Water Quality that the facility's discharge
frequency and duration enable chronic sampling according to either the North Carolina Ceriodaphnia
Chronic Whole Effluent Toxicity Procedure or to Section 8.3, in Methods EPA-821-R-02-013, the
• permit may be re-opened and modified to include chronic toxicity tests.
If the Permittee monitors any pollutant more frequently than required by this permit,the results of such
monitoring shall be included in the calculation&reporting of the data submitted on the DMR& all AT
Forms submitted.
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. (3) DISCHARGE MONITORING REPORTING WAIVER
According to the Division's records, the facility currently has a reporting waiver for submitting
Discharge Monitoring Reports (DMRs) as wastewater is currently recycled back to the head of the
facility and is not actively discharged. If or when a discharge to the receiving stream stated in this permit
is ever intended or needed,notification to the Asheville Regional Office and the Central Office is
required.
A. (4) ELECTRONIC REPORTING OF MONITORING REPORTS
[NCGS 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted 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)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

NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband access,
then a temporary waiver from the NPDES electronic reporting requirements may be granted and
discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms
approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See
"How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21,2020,the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and '
• Clean Water Act(CWA) Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see"How to Request a
Waiver from Electronic Reporting" section below)..
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9),the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website resources to identify the initial
recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program)that is the designated entity for
receiving electronic NPDES data[see 40 CFR 127.2(b)].
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-

Permit NC0074306
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
