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 (TCE), 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
Re ports 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:

Footnotes:
1. Beginning no later than December 21, 2016, the Permittee shall submit discharge Monitoring
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)].
Condition: The Permittee shall discharge no floating solids or foam visible in other than trace
amounts.
A. (2.) CHRONIC TOXICITY - PERMIT LIMIT (QUARTERLY)
[ 15A 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,
quarterZY monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent
Bioassay Procedure," Revised February 1998, or subsequent versions or, "North Carolina Phase II 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 H Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
Page 3 of 7

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.

1. Reporting Requirements !Supersedes Section D. (2.) and Section E. (5.) (a)]
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:
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 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).

Permit NC0083658
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.
