Subject: Issuance of NPDES Permit NCO083658
former HeatCraft Site - GW REM, Class PC-1
602 Sunnyvale Drive, Wilmington, NC
New Hanover County
Dear Mr. Heim:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the
subject facility. We issue this permit 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.
Changes for Renewal. In compliance with EPA/NC's updated surface water -quality criteria and
standard for Trichloroethylene (TICE), we have lowered your TCE permit limit from 30.0 ug/L to 3.0
ug/L (both Monthly Average and Daily Maximum), considering a discharge under zero -flow receiving -
stream conditions [see A. (L)]. The monitoring frequency has increased from 1/Month to 2/Month,
per NCAC 15A 2B.0505. Based on correspondence with Daikin's Paul Heim [Joe Corporon, NPDES,
02Dec2016], DWR is assured that the current remediation system is adequate to treat TCE to 1.0 ug/L
in compliance with new TCE limits. Therefore, this permit requires no compliance period for new
limits.
The Division understands that you have made no significant changes to your treatment processes since
last renewal, but may have added shallow pumping wells, increasing influent flow. We have therefore
made only minimal changes to the remainder of your permit by updating permit format and site map.
Implementing Electronic Discharge Monitoring Reports (eDMRs). Please be advised that the Division
has implemented an electronic Discharge Monitoring Report (eDMR) program, in accord with recently
promulgated requirements by the Environmental Protection Agency (EPA). We include the details to
implement the eDMR program in this permit [see Section A. (3.)].
Federal regulations require electronic submittal of all DMRs and specify that, if North Carolina does
not establish a program to receive such submittals, Permittees must then submit eDMRs directly to
EPA. For more information on eDMRs, registering for eDMR submittal, and obtaining an eDMR user
account, please visit DWR's webpage:

Reports electronically using DWR's eDMR submittal system [See Section A. (3.)].
2. Whole Effluent Toxicity (WET) Testing; Chronic (Ceriodaphnia dubia) P/F at 90%: during
the months of February, May, August and November [see A. (2)J.
Condition: The Permittee shall discharge no floating solids or foam visible in other than trace
amounts.
A. (2.) CHRONIC TOXICITY - PERMIT LIMIT (QUARTERLY)
[I 5A NCAC 02B .0500 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 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 H 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.
NOTE: 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.
Page 3 of 7

t
Permit NCO083658
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.
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.
A. (3.) ELECTRONIC REPORTING - 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.

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), Permittee 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:

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).

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.

Dear WiRO -
Paul Heim (Daikin) called me back to say he has talked to his operator onsite, and has been assured that the
current treatment system "as is" maybe tuned to treat TCE to 1.0 ppb (-1.0 ug/L). Therefore, considering a
likely permit -effective date of 01F62017, this permit will NOT require a "compliance period" to achieve
limits.
I will re-edit the permit and email, addressed to Paul/ cc to Ray Roblin (in Texas); copies to follow.

Hey Joe,
I wasn't sure if it had gone out given the letter is dated 12-14-16. Why can't we see and have chance to comment on
these permits internally before they go out the door?
TCE is too volatile to composite so that settles that item.
So if the frequency is changed to 2x/month then will they get both a daily and a monthly limit?
I have some concerns over the condition of the system even though I'm no expert on these things. They did hook new
or additional shallow recovery wells which will likely have more iron which can cause issues per Tom Tharrington.
Tom thinks 1.5-2 years would be a reasonable compliance schedule, but you should ask them if they need one and ask
them to suggest timeframe.
Lastly, Ray Roblin is in Plano, Texas last I heard not Minnesota. Paul Heim is in Minnesota I think. You should email a
copy of this to Ray along with an add -info about new limit.

The goal of the Fast Track sewer permit program is to issue a permit in no more than 30 business days from receipt of a complete application and if
no additional information has to be requested upon full review. Please use the Department's Permit Application Tracker to determine the official

application receipt date to allow you to estimate a date for issuance and find the reviewer's name. Once issued, the record stays on the site for 30
days.
For previously issued sewer permit info or to check on sewer certification receipt status, please use the Division's Sewer Extension Permit
Tracker. Using the Issue Date on top of the Engineer Certification Form is best way to ensure getting what you want especially for multi -version
permits; using today's date only gives Info on the latest permit version. Confirmation using this method will replace letters and emails: it is

Wilmington, New Hanover County
Dean — This has gone to Public Notice, but I see no issue that can't be resolved during the review period.
1. Regarding the monitoring frequency, 1/Month is consistent with Class PC-1 statewide. If they have
compliance issues with their Monthly Average, they may volunteer to collect extra samples in an effort
to remain compliant. I'll ask if this may be altered, or if that's preferable.
2. With flows averaging 0.112 MGD, I see no reason not to require Composite sampling, and we can add
this to the permit final without re -notice. Your question however about TCE volatility is a good one. I
will ask the Lab.
3. Concerning compliance with the new TCE limit of 3.0 ug/L (10x lower than the previous), I too
documented your non-compliance concerns about the database during my RPA. My only suggestion is
to soften the permit by adding a "compliance period," say two years (?), to allow the Permittee time to
implement treatment system upgrades. Again, this is more stringent and would not require re -noticing
the permit.
Discussion?

Importance: High
Joe,
We hope this hasn't gone out to Notice yet.
Why is this facility allowed to do grab samples versus composite based on their flow limit? Material too volatile?
In regards to the lower limit, our review of the data from BIMS shows they have violated this new limit about 50% of the
time they have reported data since 1-2011(see attached). Consequently, we think they should have increased
monitoring to weekly ideally or at least bi-monthly and consider a monthly average limit.
They have violated the current daily limit several times and never get assessed based on current policy and would more
likely do the same. An increased sampling frequency with the lower limit would require them to manage and maintain
the system better than the currently do.
See below that I lust got from the project manager.

As a follow up to the November 17 notification to your office of the effluent TCE concentration above the permit limit
(42.3 ug/L or ppb); the system operator had rebalanced the influent flow rate and inspected the treatment system for
any faults to determine the cause of the permit exceedance. No outward system faults were identified and the
treatment plant systems were operating under normal conditions. The cause was likely greater or higher than average
flow rates from the shallow aquifer system due to the heavy rainfall in the region from the hurricane. The higher than
normal groundwater levels allowed for greater formation yield from the various pumping wells which likely provided
higher flow rates through the treatment plant. With the rebalance of the influent flow rates, the follow on testing
indicted the TCE fraction at 2.0 ug/L for testing on November 18.

The two data results for November, when averaged, provides for a mean concentration of 22.6 ug/L for this month
which should be considered compliant. I have instructed the operator to collect the December effluent sample at the
end of next week (Dec 2), so we can have a secondary result to the November 18 data just to make sure we remain
within our 30 ug/L permit limit for TCE.
If you have any questions or concerns, please contact me.

Dean — This has gone to Public Notice, but I see no issue that can't be resolved during the review period.
1. Regarding the monitoring frequency, 1/Month is consistent with Class PC-1 statewide. If they have
compliance issues with their Monthly Average, they may volunteer to collect extra samples in an effort
to remain compliant. I'll ask if this may be altered, or if that's preferable.
2. With flows averaging 0.112 MGD, I see no reason not to require Composite sampling, and we can add
this to the permit final without re -notice. Your question however about TCE volatility is a good one. I
will ask the Lab.
3. Concerning compliance with the new TCE limit of 3.0 ug/L (1 Ox lower than the previous), I too
documented your non-compliance concerns about the database during my RPA. My only suggestion is
to soften the permit by adding a "compliance period," say two years (?), to allow the Permittee time to
implement treatment system upgrades. Again, this is more stringent and would not require re -noticing
the permit.
Discussion?

Importance: High

Joe,
We hope this hasn't gone out to Notice yet.
Why is this facility allowed to do grab samples versus composite based on their flow limit? Material too volatile?
In regards to the lower limit, our review of the data from BIMS shows they have violated this new limit about 50% of the
time they have reported data since 1-2011(see attached). Consequently, we think they should have increased
monitoring to weekly ideally or at least bi-monthly and consider a monthly average limit.
They have violated the current daily limit several times and never get assessed based on current policy and would more
likely do the same. An increased sampling frequency with the lower limit would require them to manage and maintain
the system better than the currently do.
See below that I must got from the aroiect manager.

Daikin Applied Americas, Inc.
Former Heatcraft Remediation Site
602 Sunnyvale Drive, Wilmington
Ms. Thedford:
CORR Environmental Resources Inc. (CORR) as an authorized representative of Daikin
Applied Americas, Inc. (DAA) is submitting one original and two copies of the enclosed
request for a NPDES permit renewal for existing permit number NC0083658. The
renewal application is in reference to the groundwater remediation water treatment
system at the former Heatcraft property located at 602 Sunnyvale Drive in Wilmington,
New Hanover County. The environmental remediation is overseen by the NCDEQ
Hazardous Waste Section (HWS) with EPA ID# 057 451270.
The following items are included with the renewal application:
• NPDES Permit Application — Short Form C-GW;
• Letter of delegation by DAA for CORR to act as an Authorized Representative to
prepare and submit the application;
• A topographic map indicating the location of the property and the outfall location;
• An Expanded Site Plan presenting prominent site features including the outfall
001 location along with longitude and latitude coordinates;
• A signed narrative description of the sludge management plan for the facility; and
• A data summary (as Table 1) of the monthly 2015-2016 effluent and quarterly
influent laboratory testing results. Also included is the most recent aquatic
toxicity testing report for the quarterly discharge sampling conducted in May
2016.
Since the last permit renewal in 2011 and as recommended and approved by the HWS
in 2014, a phase separation hydrocarbon recovery system was installed in one area of
the site property. One additional recovery well was added to the extraction well array as
EW-8. EW-8 was installed within a backfilled excavation where high concentration soil
_ contamination was remediated in calendar year 2012. The extraction well was installed
to a depth of approximately 6-ft below ground surface to collect residual groundwater
impacted with latent hydrocarbon liquids and dissolved chlorinated solvents such as
trichloroethene (TCE).

The hydrocarbon liquids are a mixture of mineral and motor oils with minor percentages
of diesel fuel and kerosene type products in the matrix. The recovery operation uses air
lift pumps which collect free phase liquids for transfer to a 500-gallon separation tank.
., The separation tank acts to skim the hydrocarbon liquids from the influent after settling
for collection to DOT approved 55-gallon drum(s). The resultant hydrocarbon product is
then properly disposed of at an offsite permitted hazardous waste disposal site.
As required for the permit renewal application and with the new hydrocarbon influent,
effluent samples were collected for semi -volatile organic constituent analysis (SVOC)
using EPA Method 8270 by a North Carolina certified laboratory [SGS Laboratory,
NC#481]. Total lead testing was also conducted using SW846 Method 6010. No SVOC
or lead constituents were indicated above the various laboratory Method Detection
Limits (MDLs). Effluent is also tested on a monthly basis for the full VOC constituent
analysis using EPA Method 8260B. The May 2016 analytical testing report is appended
to the renewal application. The attached drawings are presented to provide the DWQ
with the following information:
• Effluent outfall location map, USGS Wilmington topographic (FIG 1);
• The expanded site plan showing the full system layout and locations of various
recovery wells, monitoring wells, treatment system, lift station and the NPDES
effluent outfall [001] (FIG 2);
• The conceptual process flow diagram (DWG 2);
.. • The lift station piping layout (DWG 5);
• The treatment system layout including the separation tank and drum container for
phase separated product collection (DWG 12);

.. Former Heatcraft Site NPDES #NC0083658

am Site History
Daikin Applied Americas, Inc., (formerly AAF-McQuay Inc), a successor to the
04 Refrigeration Products Group of SnyderGeneral Corporation, was the former owner of
the Heatcraft facility. The facility is located in New Hanover County at 602 Sunnyvale
Drive, Wilmington, North Carolina. SnyderGeneral Corporation sold the Heatcraft facility
,-, in 1986 to Lennox Industries Inc. who then sold the property to Port City Supply in late
2010. Lennox Industries continued to operate the manufacturing facility until 1988 when
the plant was shut down. In 1996, vacant space in the plant building was leased to
fm International Paper and ultimately to Port City Supply who currently operates as S&R
Packing and Crating. S&R provides shipping services to local entities. S&R is not
involved with the groundwater remediation program at the property and does not utilize
any hazardous materials or generate any hazardous wastes.
Am
Former manufacturing operations by the Refrigeration Products Group and Lennox at
the facility included the fabrication of heating and air conditioning equipment. Historically
an the fabrication of air conditioning involved the stamping and machining of various metals
into refrigeration coils which required cleaning prior to testing and shipping. The
cleaning typically involved mechanical vapor degreasing using the organic solvent
ffim trichloroethene (TCE). The use of TCE was discontinued and was replaced with 1,1,1
trichloroethane (TCA).
The facility recorded a release of TCA of approximately 400 to 500-gallons in 1983 on
the northwest side (rear) of the plant building. A second release of approximately 55-
gallons of TCA occurred in July 1987 also in the rear of the building. Subsequent to
these releases, the DEHNR — Division of Solid Waste Management required closure of
the second TCA release area by capping and implementation of a quarterly groundwater
monitoring program. In addition to the two TCA releases, the facility also experienced a
localized release of fuel oil from underground storage tanks on the southwest corner of
the property.
DAA began groundwater remediation from a single extraction well at the site in 1994.
Groundwater treatment was effected by air stripping technology to remove the volatile
organic compounds. During this initial phase of groundwater remediation no attempt
was made to address the localized fuel oil issue resulting from the UST release.
In 2000 DAA authorized the removal and replacement of the existing air stripping
equipment with replacement with newer technology for greater efficiency. Concurrent
with that project, additional groundwater extraction wells were installed to better control
the contamination plume beneath the plant building along Sunnyvale Drive.

The collected groundwater is then transferred from the lift station, via double walled
piping, over and across the roof of the plant building to the treatment system at the rear
of the plant building.

e" Drawing 22 — Presents a detailed layout of the treatment system.
The only modification made to the groundwater treatment and extraction system at the
site since the 2011 NPDES permit renewal was the addition of one shallow extraction
well for removal of latent free phase hydrocarbons on the rear of the property. This
extraction well, coupled with pre-existing wells EW-101 and EW-7, were fitted with
pneumatic lift pumps for transfer to a separation tank. The separation tank acts to settle
(float) the liquid hydrocarbons for skimming to 55-gallon accumulation drum for proper
offsite disposal. The resultant nuisance water is then allowed to gravity feed to the
primary accumulation tank and to the air stripping treatment unit. The air stripping
treatment process has remained the same.
The receiving water ditch on the south side of the property flows to the east and
Sunnyvale Drive where it flows via a culvert to the ditch parallel to Sunnyvale Drive to
the south where it flattens to a low lying area to the east toward Barnards Creek.
Barnards Creek is a local tributary to the Cape Fear River at a distance of several miles
from the outfall. The system contaminant load and source of the impacts remain as in
previous permit renewals.

Sludge Management
Former Heatcraft Remediation Site
NC0083658
Currently no sludge or solid wastes are generated during the groundwater treatment
activities. No industrial waste water is included in the influent stream and site related
groundwater contaminants are volatile organic compounds (VOCs); primarily
trichloroethene (TCE), and 1,1,1 trichloroethane (TCA) and their degradation breakdown
products dichloroethene and vinyl chloride. The VOC contaminants are off -gassed
during the air stripping operation and no residuals remain after treatment. The only solid
waste generated is accumulated dirt (sediments) and windblown sand which collects in
the secondary containment area sump. These solids can include pine tree needles and
leaves which are removed as warranted maintaining operation of the sump. These
solids are removed from the sump and placed in DOT approved 55-gallon drum for
nearly immediate disposal. The removal of sediments/solids from the sump happens on
average every two years or greater. The drum is properly disposed of as hazardous
waste by contract to an approved vendor to Daikin Applied. Waste disposal transport
manifest(s) and disposal certification documents are filed on site when received from the
vendor.
The basic groundwater recovery system now includes the use of two additional
groundwater extraction points (shallow wells) at the rear of the facility as a change from
the 2011 permit renewal application. These two additional extraction point wells were
required by the NCDEQ Hazardous Waste Section. The remedial activity removes free
phase hydrocarbon liquids (primarily diesel fuel, motor and mineral oils). These liquids
are piped to an above ground tank (-500-gallons) which uses gravity separation to skim
the hydrocarbons from the influent groundwater. The skimmed hydrocarbon liquids are
containerized in DOT approved 55-gallon drums. The skimming operation typically
recovers less than one 55-gallon drum on a semiannual basis. The separated
groundwater is then added to the other dissolved solvent recovery well influent(s) to the
air stripping treatment units.
The skimmed/separated hydrocarbon liquids are then containerized in DOT approved
55-gallon drums and properly disposed of as a hazardous waste (F002 and/or D043) as
required by law.
