' 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:

' Site History
Daikin Applied Americas, Inc., (formerly AAF-McQuay Inc), a successor to the
t 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
' 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.
1 Former manufacturing operations by the Refrigeration Products Group and Lennox at
the facility included the fabrication of heating and air conditioning equipment. Historically
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
' 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 attached Figures identify the site as it currently exists for the proposed NPDES
discharge permit. The following Figures are appended to the renewal application:
Figure 1 — The USGS topographic map, 1:24,000 scale, Wilmington, North Carolina
1969, photo revised 1993. The map presents the approximate location of the single
' treatment system effluent outfall.
Figure 2 — The Expanded Site Plan base map identifying all pertinent site features and
' landmarks including improvements and wells.
Drawing 2 —The conceptual process flow diagram of the groundwater treatment system
as currently configured.
Drawing 5 — Depicts the year 2000 lift station at extraction well EW-3, updated as of
June 2011. Extracted groundwater from EW-3 and recovery wells EW-2, EW-4 and EW-
5, located parallel to Sunnyvale Drive manifold via double walled piping to a lift station.
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.
Drawing 12—Depicts the layout of the treatment system as it is currently configured.
' Drawing 14—Oil separator detail plan.
t 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.
