RE: Corrective Action - Permit Exceedance --July 2019
Radiator Specialty Company
Indian Trail, Union County, North Carolina
Permit No. NC0088838
Dear Mr. Watson:
Radiator Specialty Company (RSC) respectfully submits for your review', this
written submission of a status update to a noncompliance that occurred in July 2019 to
National Pollutant Discharge Elimination System (NIPDES) Permit No. NC0088838,
On July 25, 2019, RSC received the analytical results associated with the July 16,
2019 quarterly sample collected from Outfall 001 The results indicate the presence of
tetrachloroethene at a concentration of 6.7 micrograms per liter (pg/t) and 1-4,dioxane at
a concentration of 230 !AWL These concentrations exceed the Permit limits of 3.3 lag/
-for tetrachloroethene and 80 ug/t, for 1,4-dioxane, respectively,.
Based on preliminary information provided by the analyzing laboratory on July 23,
2019, RSC shut the groundwater recovery system down. Following discontinuing the
discharge, RSC' sampled the equalization tank and each individual recovery well for the
subject parameters. Based on the results of these samples, RSC proposes to perform the
following corrective actions.
Recirculate the collected groundwater in the equalization tank through the air
stripping tower to reduce the concentration of the contained water to below the
permitted limit for tetrachloroethene,
RS(... will replace flow/meters on two recovery wells. Nev calibrated llowme
will assist RSC in manually operating the four (4) recovery wells.

Dear Mr. W'at on:
Radiator Specialty Company (RS() respectfully submits for your review, this
written submission of a noncompliance as required by Section E(6)(a) of National
Pollutant Discharge Elimination. System (NPDES) Permit. No. NC0088838.
On July 25, 2019, R.SC received the analytical results associated with the July 16,
2019 quarterly sample collected from Outfall 001. The results indicate the presence of
tetrachloroethene at a concentration of 6.7 micrograms per liter (µg/L) and 1-4,dioxane at
a concentration of 230 µg/L. These concentrations exceed the Permit limits of 3.3
for tetrachloroethene and 80 µ.g/L for 1,4-dioxane, respectively_
Folio w ing receipt of this data, on July '26t1t I .SC contacted Mr. Edward Watson of
the North Ca. rolit
advised hum. of these results.
epartrnent of Environmental
Quality Division of Water Quality and
Due to issues with the Program Logic Controller (PL+C'), the system has been shut
down since July 23, 201.9.
Based on a review oftlte sampling and analytical protocolour opinion that
the sample bottles used in the July 16 sampling event may have been contaminated.,
resulting in these exceedances. To confirm this opinion, 'R.SC is collecting samples of
the water currently stored in the equalization tank and the effluent following treatment of
the stored water. These samples will allow us to verify the treatment efficiency and
potentially evaluate the need for treatment system service. Should the data indicate a

Mr. Kerkhoff:
The Division has completed a preliminary review of your NPDES renewal application and noted two important changes .
that will occur in this renewal.
1) Any submitted toxicity testing will require a composite be taken as the test sample (you may already being doing
this).
2) The presents of 1,4 dioxane in the influent and ground water sources will require the addition of monthly 1,4
dioxane monitoring with a 80 pg/L daily limit to protect for the Human Health surface water quality standard.
Based on the historical data reported to other NCDENR Divisions (data above 80 µgIL) additional treatment
technology will be require to remove the 1,4 dioxane to meet the daily limit.
Note: We are allowed to apply the QA steam flow for dilution but no value is available so you may contact USGS
and obtain the QA value for your designated discharge location. However, as seen previously at this discharge
location the estimated stream flows are very low flows, in fact a definable QA flow may not exist or its impact to
an adjusted daily limit may be small. The current air stripping process will most likely will have no impact on 1,4
1

dioxane removal. Under current legislation you are not required to obtain an Authorization to Construct permit
as before.
Before proceeding with this renewal, your input as far as providing a QA stream flow if you so choose and a time frame
to completed the necessary treatment changes for 1,4 dioxane removal is required. If you have any additional influent
data from 2011 to present for 1,4 dioxane please provide.
If you have any questions let me know.

Subject: Final NPDES Permit Renewal
Permit NC0088838
Radiator Specialty Company
Union County
Facility Grade I
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
Please note that the receiving stream is listed as impaired for fish community (fair) and benthos
(poor). on the North Carolina Final 2014 303(d) Impaired Waters List. Addressing impaired waters
is a high priority with the Division, and instream data will continue to be evaluated. If there is
noncompliance with permitted effluent limits and stream impairment can be attributed to your
facility, then mitigative measures may be required.
The Division received your comments in a letter dated March 14, 2018 and the following
changes were made to the draft permit sent to you on February 7, 2018:
• Monitoring frequency for TSS has been reduced from monthly to quarterly in light of
reviewed effluent data showing consistent compliance with permit limits, yielding 7%
detection over the span of eight years (from February 2010 through February 2018). TSS
monitoring will remain in the permit as this is a pollutant of concern and a parameter
routinely put in groundwater remediation NPDES permits.
• Monitoring frequency for pH has been reduced from monthly to quarterly in light of
reviewed effluent data showing consistent compliance with water quality standards. pH
will remain in the permit as this is a pollutant of concern and a parameter routinely in
groundwater remediation NPDES permits.
('Nothing Compares��..
State of North Carolina I Environmental Quality
1611 Mail Service Center I Raleigh, North Carolina 27699-1611
919-707-9000

• The facility component list on the Supplement to Permit Cover Sheet was revised by
removing "with recorder" for the effluent meter per your request after verifying that the
meter does not have a chart or other recording device, but flow readings are taken manually
on a daily basis.
• 1,4-Dioxane limits and monitoring will remain in the permit as this parameter does have a
NC calculated surface water criterion of 80 µg/L to protect human health in Class C waters.
The reopener will remain in the permit to allow for changes to address 1,4-Dioxane
monitoring, treatment and/or compliance.
1,4-Dioxane samples shall be analyzed by a NC certified laboratory using EPA Test Method
624.1, and results shall be reported to the lower reporting level of the procedure. In September
2017, EPA promulgated the 2'017 Methods Update Rule approving test method 624.1 for 1,4-
Dioxane. All tests for parameters listed in the NPDES permit must be performed in accordance
with EPA approved test methods and by a NC certified laboratory. Currently, there are several
laboratories certified in NC to perform 1,4-Dioxane testing. Radiator Specialty is required to
submit effluent data results on 1,4-Dioxane using one of these certified labs. To learn what
certified labs are in your area, please contact Data Satterwhite, DWR Laboratory Certification
Branch, at 919-733-3908 ext. 202 or by e-mail: dana.satterwhite@,ncdenr.gov.
The final permit maintains the following significant changes identified hi the letter sent on
February 7, 2018:
• Removed monitoring for Chloroethane from this permit, since an evaluation of submitted
effluent data found no reasonable potential to exceed the EPA criterion of 550 µg/L.
• Removed monitoring for 1,1-Dichloroethene; 1,2-Dichloroethene (total); 1,1,1-
Trichloroethane; and 1,2-Dichloroethane have been removed from this permit. These
parameters are no longer pollutants of concern, based on reasonable potential evaluation
and no significant levels in the influent.
• Revised daily limits for Tetrachloroethene and Vinyl Chloride. The 2015 EPA Human
Health water quality criterion for these parameters was applied in this permit (technical
change).
• Added monitoring with limits for pH. The pH is a pollutant of concern and the freshwater
standard for Class C waters was applied in this permit.
• Added quarterly monitoring and a limit of 80 µg/L for 1,4-Dioxane to the permit with
provisional monitoring increase to monthly if a sample measurement is equal to or
greater than the limit. Added special condition A. (3.) REOPENER 1,4-DIOXANE in
this permit. Adjacent monitoring wells data indicate potential migration of this pollutant
to the groundwater remediation collection system, thus a potential for this pollutant to
be present in excess of its WQBEL which may require modification of the permit to
address compliance.
• 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. 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 this permit. [See
Special Condition A. (4)]

unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this Ietter. 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 decision 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 other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental permits that may be required.

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriadaphnia 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
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 subsequentversions.
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:

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 I, 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

(Continued A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS)
• 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 EIectronic Reporting
Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-
pollutant-discharge-elimination-system-npdes-electronic-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 perrnittees 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.

Subject: NPDES Electronic Reporting Requirements and
Sixty Day Notice of Minor Modification of the NPDES Permit
Radiator Specialty Company
NPDES Permit Number: NC0088838
Dear NPDES Permittee:
S. JAY ZIMMERMAN
The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge
Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to
report information electronically, instead of filing written paper reports. The rule does not change what
information is required from facilities. It only changes the method by which information is provided (i.e.,
electronic rather than paper -based)..
EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their
key milestones, are:
Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge
Monitoring Reports (DMRs) will begin submitting these reports electronically. If you are currently
reporting your DMR data electronically using eDMR, then you simply need to continue reporting
in the same way as you are now. The key change is that, starting on December 21, 2016,.
electronic reporting of DMRs will be required, instead of voluntary.
Phase 2 —Starting on December 21, 2020, regulated entities that are required to submit certain
other NPDES reports will begin submitting these reports electronically. Reports covered in the
second phase include Notices of Intent to discharge in compliance with an NPDES general permit,
Sewer Overflow/Bypass Event Reports, and a number of other NPDES program reports.

Mr. Kerkhoff,
I had forwarded you request letter to continue grab sampling for the chronic toxicity test at the Radiator Specialty
Company NC0088838 facility to the Aquatic Toxicity Branch for review and for a final decision on the required sample
method. In regards to the 1,4,-dioxane, I concur on moving forward with data collection and evaluation. Therefore, I
am setting a due date no later than April 6, 2015 for your submittal to the Division of the design of the necessary
treatment and/or operation changes to remediate the worst case effluent 1,4 —dioxane levels occurring above 80 µg/L
to less than 80 µg/L. As far as the correct test method, the method must be capable of minimum detection to Tess than
80 ug/L which apparently the proposed method can do provided the lab is calibrated appropriately. The design must
include a reasonable time table to implement the proposed changes.
If you have any questions let me know.

Dear Mr. Berry:
RECEIVED/DENRIDWR
SEP 2 5 2014
Water Quality
Permitting Section
Radiator Specialty Company (RSC) appreciates this opportunity to respond to the two
proposed changes to the pending National Pollutant Discharge Elimination System
(NPDES) Permit renewal for Permit No. NC0088838. For ease of review, we have
presented the North Carolina Department of Environment and Natural Resources
(DENR) intended incorporations from your August 5, 2014 e-mail in italics followed by
RSC's response.
1. Any submitted toxicity testing will require a composite be taken as the test sample.
We understand that composite samples are typically required for NPDES permitted
facilities with either an intermittent discharge and/or the potential for variability in the
waste stream over a twenty-four (24) hour period. The groundwater recovery and
treatment system at Radiator Specialty Company discharges approximately 40,000
gallons of treated groundwater per day. The discharge flow is driven by the pumping of
groundwater from four (4) on -site recovery wells. As a result, the system discharges
continuously each day. Since the source of the water is limited to the four (4) recovery
wells, the influent water quality is well documented and variability in the waste stream
has not previously occurred and is not expected to occur in the future. As a result, grab
samples adequately represent the water quality For toxicity testing.
DENR has accepted this approach at at least one other facility with a similar discharge.
A May 8, 2014 determination by Ms. Cindy Moore. Mr. Tom Belnick and Mr. Wes Bell
of DENR authorized Equipment & Supply. Inc. (NPDES #0087858) to revise the toxicity
sampling protocol from composite to grab. The groundwater treatment and discharge

system a
RSC.

Equipment & Supply, Inc. facilty is comparable to the system operated by
RSC requests the toxicity sampling protocol not be revised.
2 The presence of .1,4-diosane in the influent and groundwater sources will require
the addition of monthly 1,4-dioxane monitoring with CM 80 microgram per liter
(Alga) daily limit to protect for the Human Health swjace water quality standard
.RSC is aware that 1,4-dioxane has historically been detected in groundwater samples
collected from the site and is not opposed to analyzing the effluent for 1,4-dioxane.
However, this parameter is not targetedby standard method 624, the analytical method
currently required by the facility's Permit. Based on an August 11, 2014 telephone
conversation with you, RSC understands DENR would accept modifying the 'Permit
during the renewal process to specify SW-846 Method 8260 instead of Standard Method
624 for targeted volatile constituents. Further, based on this conversation, RSC
implemented this analytical method change during the August 2014 monthly sampling
event.
The Method Reporting Lirnit for SW-846 Method 8260 is 150 µgill— Prism Laboratories,
Inc. has indicated that a normal Method Detection Limit for SW-846 Method 8260 is
10.6 ug/L. Should 1,4-dioxane be detected in the effluent sample at a concentration
between the permit limit and 150 ugit„ the result would, be reported as a "J" value,
Based on our telephone conversation on August 11, 2014.. RSC anticipates three (3) to six
(6) months will be necessary to collect and evaluate I ,4-dioxane analytical results to
determine if changes to the existing groundwater recovery system are necessary,
RSC appreciates DENR allowing us to review its recommended changes prior to issuing
the draft permit renewal. Please call if you have any questions or require any additional
information.

Radiator Specialty Company

Noted by Ed Watson:
A review of historical groundwater analytical results indicate the presence of chlorinate volatile organic
compounds (CVOC's) in the onsite groundwater. However, these values have been shown to be being
reduced by the on -site remediation efforts. Trichloroethane and several of its various daughter products
remain in concentration in exceedance of the NC 2L standards. Historic reported values indicate these
constituents are moving forward with the expected degradation of chlorinated solvents,

reviewed for the period February 2013 through February 2014. The reports indicate
that the permittee was meeting permit effluent limits and monitoring frequency
requirements during the review period with the following exception. A tetrachloroethene
concentration of 5.8 ppb was reported on Nov. 14, 2013, which exceeded the daily
maximum permit limit of 3.0 ppb. This exceedance was handled under separate cover
through the issuance of a Notice of Violation (NOV-2014-LV-0121). Additional analyses
were conducted on the effluent in Nov. and Dec. 2013 but were not reported on the
respective DMRs; all effluent analyses must be reported to the DWR as per Section E,

NPDES Permit No. NC0088838

Dear Mr. Kerkhoff :
A recent file review found that the Division of Water Quality (DWQ) compliance reporting database
has flagged the September 2012 Radiator Specialty Company discharge monitoring report (DMR)
with a permit monitoring violation for the monthly reporting of tetrachloroethene. The compliance
system generates violations after the data from your monthly DMRs have been entered and
compared with the requirements of your permit, NC0088838.
A physical review of the September DMR found that Radiator Specialty Company reported a
tetrachloroethene concentration on September 20, 2012, using the EPA parameter code of 34475
(noted at the top of the reporting column). However, the DWQ compliance reporting database has
been programmed to require tetrachloroethene concentrations be reported using EPA parameter
code 78389. Your reporting code must match the code in our compliance database for the data entry
staff to log your monitoring results and credit you with the required monitoring.
From this point forward, please change your reporting code for tetrachloroethene from 34475 to •
78389 to prevent monitoring violations from being generated in our compliance database and being
passed along to the EPA Echo compliance database available at htto://www.epa-echo.00viecho/. If
you have questions concerning this matter, please do not hesitate to contact me at [phone] or
[e-mail].

A. 2 CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
t4 Yl
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 February 1998, or
subsequent versions or "North Carolina Phase Il Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing 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 -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) 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, DWQ
Form AT-3 (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, 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 Environmental 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. Should any test data from this monitoring requirement 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. If the Permittee
monitors.any pollutant more frequently then 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, 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.
