Subject: Issuance of NPDES Permit Renewal
Permit No. NC0025984
Town of Forest City WWTP
Rutherford County
Facility Class IV
Dear Mr. Condrey:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is
issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
Through further review, several changes were made to the draft permit sent to you on
December 16, 2015:
• According to the information provided by the Town of Forest City, the Forest City WWTP
treatment components list was updated in the permit;
• Monitoring for total copper has been removed from the permit since effluent samples did not
demonstrate reasonable potential to exceed applicable water quality standards and the
maximum predicted concentration was < 50% of the allowable concentration. Monitoring for
copper shall continue as part of the Town's pretreatment Long Term Monitoring Program;
• The permit expiration date was modified to July 31, 2019 on the permit cover sheet;
• Effluent Toxicity footnote in the Effluent Limitation page has been updated to include the
requirement of "Toxicity monitoring shall coincide with metals monitoring";
• Testing requirement months for chronic toxicity in Special Condition A. (2.) have been
modified as January, April, July, and October to be consistent with the Effluent Toxicity
footnote in the Effluent Limitation page;
• Electronic Discharge Monitoring Report (eDMR) requirements have been updated. Three main
revisions include: 1) Electronic reporting of DMR data is required effective December 21,
2016; 2) Electronic reporting requirements of compliance monitoring data and reports have
been added; 3) A section has been added on how to request an electronic reporting waiver.
Footnote #1 under Section A. (1.) was revised to state "No later than 264 days from the
effective date of this permit, begin submitting discharge monitoring reports electronically using
NC DWR's eDMR application system" and Special Condition A. (4.) was updated to reflect
the eDMR reporting deadline of December 21, 2016.

A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
[15A NCAC 02B .0200 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 18%.
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.
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

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.

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 DENR / 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
Part I, Page 7 of 9

Permit NC0025984
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. 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://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr

belt filter press, sludge dryer (will be phased out and scrapped in 2016), and storage bin. The
Town's current permit WQ0010926 for Class A distribution of residuals is for maximum of 500
dry tons per year. However, due to the failure of the sludge dryer in 2015, Forest City is now

using belt press to dewater the sludge prior to hauling the residuals to the Anson County Landfill.
The Town is working on the application for a class B land application permit.
Receiving Stream:
The Forest City WWTP discharges to the Second Broad River in sub basin 03-08-02 of the
Broad River Basin. Second Broad River is currently classified as WS-IV waters and is not listed
on the NC 2014-303(d) list for impaired streams.
Current Effluent Characteristics:
The WWTP's average flow was 1.06 MGD during the 1 year period of October 2014 through
September 2015, which represents 21.4% of permitted flow. Monthly average flow ranged from
0.91 MGD to 1.36 MGD.

Reasonable Potential Analysis (RPA) and Effluent Pollutants Scans:
A reasonable potential analysis (RPA) was conducted utilizing DMR data from February 2012
through August 2015, supplemented with four effluent pollutant scans (1st quarter of 2010, 2nd
quarter of 2011, 3rd quarter of 2012, and 2nd quarter of 2015). Effluent samples for arsenic,
cadmium, chromium, cyanide, lead, molybdenum, nickel, selenium, and silver were less than
detection limits.
Reasonable potential analyses were conducted for total phenolic compounds, chloroform, total
copper, and total zinc.
• No Limit or Monitoring. The following parameters will not receive a limit or monitoring,
since they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was <50% of the allowable
concentration: total phenolic compounds, total copper, and chloroform.
• Monitoring Only. The following parameters will receive a monitor -only requirement
since they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria, but the maximum predicted concentration was > 50% of the allowable
concentration: total zinc.
A spreadsheet of the RPA results is attached to this Fact Sheet. Note Quarterly monitoring for
arsenic, cadmium, chromium, copper, cyanide, lead, mercury, molybdenum, nickel, silver,
selenium, zinc, and phenols will continue as part of Town's pretreatment LTMP.
Color Monitoring:
The 2009 Permit Renewal Fact Sheets indicated that the last two quarter samples in 2008
(August and November) for effluent color showed descending trend. It also recommended that
Forest City WWTP
NPDES Renewal
Page 2

Permit No. NC0025984
quarterly color monitoring remained in the LTMP for at least another twelve months to track and
verify the reduction in effluent color. Effluent data was reviewed from January 2012 through
May 2014. 16 out of 18 effluent color samples showed values less than 25 ADMI; two detections
were reported as 30 ADMI (8/21/2013) and 31 ADMI (9/18/2013). A major textile mills
company, Hanes Brands Incorporated, dropped from the Town's LTMP industrial users list in
July 2009. Effluent color is less likely to be a parameter of concern. No monitoring requirements
will be recommended to the LTMP.
Evaluation of Compliance Data:
DMRs have been reviewed for the period September 2010 through September 2015. Four limit
violations occurred during this time period: cyanide exceeded the daily maximum limit on
3/11/2011, total suspended solids concentration exceeded the weekly average limit on 3/12/2011
and 5/19/2012, and total suspended solids concentration exceeded the monthly average limit on
5/31/2012. All of these violations proceeded to an enforcement case.
The last routine Compliance Evaluation inspection was conducted on October 27, 2015 and the
facility evaluation rating was compliant. A Pretreatment Compliance inspection was performed
on the same date, and the inspector rated the facility as compliant/satisfactory.
Toxicity Testing. Since January 2010 the facility has passed 23 of 23 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).
The special condition regarding reevaluation of limits for Forest City WWTP if the upstream
Forest City Water Treatment Plant (WTP) should expand beyond 8 MGD withdrawal, should
remain in the permit. The expansion of the water plant would affect the 7Q10 of the Second
Broad and possibly require more stringent limits for the WWTP. See details in NPDES WLA
Report dated Sep. 1994.
Evaluation of Instream Data:
A review of instream data from August 2012 through September 2015 showed no violations or
concerns related to dissolved oxygen, temperature, conductivity, or fecal coliform. Dissolved
oxygen remained well above 4 mg/L throughout, and temperatures appear seasonally appropriate,
with no significant increases evident. In most instances conductivity was elevated downstream
as compared to upstream, but of little concern based on passing results in all effluent toxicity
tests. Downstream fecal coliforms were low unless a high upstream number occurred as well,
and in some instances lower downstream than upstream. Since the discharge stream is not
classified as B water and it is not impaired for fecal coliform, instream monitoring of fecal
coliform has been removed from the permit.
Mercury TNIUL 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 66.4 ng/L and the Technology Based Effluent Limitation (TBEL) of 47 ng/L. A
review of low level effluent mercury data from February 2012 to August 2015 showed annual
averages were below both the WQBEL and the TBEL (displayed in table below). However,
multiple sample detections exceeded 1 ng/L, therefore a Mercury Minimization Plan is required
[see A (5)]. The Permittee will be required to continue monitoring mercury as part of its effluent
pollutant scans, using EPA test method 1631 E.

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 points: 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 include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four 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 QAIQC 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 four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evacuation, 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.
