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
1623 Mail Service Center
Raleigh, North Carolina 27699-1623

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. (4) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports and specify that, if a state does not establish a system to receive such submittals, then
permittees must submit monitoring data and reports electronically to the Environmental Protection
Agency (EPA). 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
Effective December 21, 2016, 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
Page 7 of 9

Permit NC0021601
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 3 16(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: http://www2.epa.gov/compliance/final-national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
Page 8 of 9

Permit NC0021601
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/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
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:
http://deq.nc.gov/about/divisions/water-resources/edmr

Background for Permit Renewal
The Town of Tryon WWTP is a Class III facility with a permitted flow of 1.5 MGD. This facility
serves a population of 2,400 and one Significant Industrial User (SIU), Carolina Yarn
Processing. Carolina Yarn Processing is a textile mill that produces bleached and dyed synthetic
and natural yarn. Since the Town of Tryon WWTP has one SIU, it has a modified pretreatment
program with the Division of Water Resources' Pretreatment Unit and will continue to
implement this program in the new permit term. The current permit expired on December 31,
2013, and has been administratively extended. The Permittee submitted EPA Form 2A on March
27, 2014 in order to request renewal of the permit. The facility has not requested any changes to
the permit.
Receiving Stream
This facility discharges to Vaughn Creek in subbasin 03-08-06 of the Broad River Basin.
Vaughn Creek is currently classified as C waters and is not on the 2014-303(d) list.
Current Effluent Characteristics
The WWTP's average flow was 0.40 MGD during calendar year 2014, which represents 26.6%
of permitted flow. Monthly Average flows ranged from 0.11 MGD to 1.12 MGD.

Reasonable Potential Analysis (RPA) and Effluent Pollutant Scans
Reasonable potential analysis (RPA) was conducted utilizing DMR data from July 2012 — May
2015, supplemented with three effluent pollutant scans. Results of the RPA are summarized
below and also provided in the attached RPA summary sheet.
• The following parameters showed no reasonable potential and maximum predicted values
were < 50% of allowable concentration, therefore monitoring for arsenic, chromium,
fluoride, lead, and nickel is not required.
• The maximum predicted values for copper demonstrated reasonable potential to exceed
the chronic and acute allowable concentrations. However, copper has an action level
standard and is reviewed in conjunction with toxicity testing results. The facility has
passed all toxicity tests since March 2010; therefore quarterly monitoring is required.
• The following parameters showed no reasonable potential but maximum predicted values
were > 50% of allowable concentration, therefore quarterly monitoring for chlorides,
cyanide, selenium, and zinc is required.
• One reported detection of chloroform at 2.8 ug/L (9/2/2014) is well below the EPA
human health criteria of 170 ug/L therefore monitoring is not required.
Evaluation of Instream Data
A review of instream data from May 2012 through May 2015 showed no violations or concerns
related to dissolved oxygen, temperature, conductivity, or fecal coliform. Dissolved oxygen
remained well above 4mg/L throughout, and temperatures appear seasonally appropriate, with no
significant increases evident. Conductivity was elevated downstream as compared to upstream,
but of little concern based on passing results in all effluent toxicity tests. Fecal coliforms were
low unless a high upstream number occurred as well. Upstream and downstream monitoring of
fecal coliform has been removed from the permit.
Evaluation of Compliance Data
DMRs have been reviewed for the period May 2010 through May 2015. No limit violations have
occurred during that time period. Although several reported TRC values exceeded the 28 µg/L
daily maximum limit, the facility is considered compliant with its permit since all reported values
were less than 50 µg/L.
The last routine Compliance Evaluation inspection was conducted on November 25, 2014 and
the facility evaluation rating was compliant. On August 12, 2015 a Pretreatment Compliance
inspection was performed and the inspector rated the facility as compliant/satisfactory.
Toxicity Testing. Since 2010 the facility has passed 21 of 21 chronic toxicity tests. In addition to
quarterly chronic toxicity testing, the facility has also passed 4 of 4 second species toxicity tests
utilizing the fathead minnow (pimephales promelas).

. Mercury TMDL Evaluation
In accordance with the 2012 Mercury TMDL NPDES Guidance the permittee needs to show
annual mean effluent concentrations below the Water Quality Based Effluent Limitation
(WQBEL) of 32.6 ng/L and the Technology Based Effluent Limitation (TBEL) of 47 ng/L. A
review of low level effluent mercury data from August 2012 to March 2014 showed annual
averages were below the WQBEL and the TBEL (displayed in table below); therefore no mercury
limitation is required. The permittee will be required to continue monitoring mercury as part of
its effluent pollutant scans, using EPA test method 1631 E.

Summary of Proposed Changes
The following changes are proposed for this permit renewal:
1. Addition of Monthly Average and Weekly Average effluent NH3 limits
2. Addition of eDMR reporting requirement
3. Addition of quarterly monitoring for Cyanide and Selenium based on reasonable potential
4. Increase effluent monitoring frequencies to reflect 2B.0500 requirements for Class III
facility
5. Deletion of instream fecal monitoring requirement
6. Deletion of monthly mercury monitoring based on RPA result; default to three effluent
pollutant scans and pretreatment STMP monitoring
7. Reduce monitoring frequency from monthly to quarterly for Chloride, Copper, and Zinc
based on lack of reasonable potential
8. Deletion of effluent monitoring requirement for Fluoride based on RPA result

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the facility's discharge paints: 1) POTWs with
a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are required to have one under 40 CFR Part 403); or 3) POTWs required by the
permitting authority to submit data for these parameters.
• At a minimum, these results must indude quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two species), or the results from tour tests
performed at least annually in the four and one-half years prior to the application, provided the results show no appreciable toxicity, and testing for acute and/or chronic toxicity,
depending on the range of receiving water dilution. Do not include information on combined sewer overflows in this section. All information reported must be based on data collected
through analysis conducted using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test conducted during the past tour and one-
half years revealed toxicity, provide any information on the cause of the toxicity or any results of a toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information requested in question E.4 for previously
submitted information. If EPA methods were not used, report the reasons for using alternate methods. If test summaries are available that contain all of the information requested
below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to complete.
E.1. Required Tests.
Indicate the number of whole effluent toxicity tests conducted in the past four and one-half years.
