Dear Mr. Khan:
On behalf of Carrier Corporation (Carrier), CP Engineering and Environmental Solutions
(CPEES) is pleased to submit the attached mitigation strategy report to address Zinc (Zn) and
Copper (Cu) issues in stormwater discharge at Carrier Corporation located in Charlotte, North
Carolina. The mitigation strategy report includes: Project background, outside activities and
past two years stormwater analytical data and our strategy to mitigate Zn and Cu at the subject
facility.
1.0 Project Background
Carrier facility located at 9701 Old Statesville Road, Charlotte, North. Carolina, Mecklenburg
County, is an industrial chiller manufacturer. The geographic site location could also be given
as 350 2 P 10" N latitude and 800 49 32" W longitude. A Site Location Map illustrating the site
vicinity on the USGS topographic map of the area is provided on Figure 1. The Site Drainage
Layout Map (Figure 2) displays the property boundaries, layout of the building facilities, and
parking lots.
The manufacturing facility is located on a 33.64 acre land with a metal building area of 340,000
sft. The concrete area around the building is approximately 310,000 sft. Two cooling towers .
exist at the facility outside the main building. An asphalt parking lot is located east of the main
facility. The majority of the facility (901/6) is surrounded by a galvanized fence.
The facility operations are permitted 6a: Charlotte -Mecklenburg Air permit, State of
North Carolina Department Energy, Mineral and Land Resource (NC DEMLR)
General Stormwater Permit, Charlotte -Mecklenburg Wastewater Permit and NC DEQ
Hazardous Waste SQG permit. In addition, the facility submits Tier 11 and TRI reports
annually. The facility strives very hard to be compliant with all Federal, State and local
environmental regulations.
The facility operates 24 hours per day and 7 days per week and 52 weeks per year.

2.0 Description of Facility U erations
The process operations at the facility include: plasma are cutting of steel, metal forming, shot
blasting, welding, copper tubing„ brazing, phosphatizing, leak testing, insulating, painting, and
shipping to the customers_ The raw materials received at the subject facility include: steel plates,
copper tubes, galvanized frames for the final equipment erection, refrigerant, oils, paint, primer,
gear oil, adhesives, corrosion shield chemicals, cooling tower chemicals and wastewater
pretreatment chemicals.
3.0_N_PDES General Stormwater Permit and Drainage Areas
The facility conducts their operations under a SIC code 3585"Air Conditioning and warm air
heating equipment and commercial and industrial refrigeration equipment''. The State of North
Camlinna Department Energy, Mineral and Land Resources (NC DEMLR), pursuant to the
requirements of North Carolina General Statute 143-215.1 covers discharge from stormwater
outfalls for Carrier Corporation (Carrier) Plant under the NPDES General Permit No.
N00030000_ NC DEMLR issued a NPDES General permit to Carrier plant with a Certificate
of Coverage (COC) NCG030452 to discharge stormwater from outfalls at the facility. The
general permit effective date is November 1, 2012 and the expiration date is October 31, 2017.
Based on the NC DELMR web site, the permits that are to be expired in 2017 were
automatically extended to 2018 as long as the permit fee was paid by the facility owner.
As a condition of the General Permit, a Stormwater Pollution Prevention Plan (SWPPP or
SWPP Plan) shall be developed and implemented in accordance with good en 'n
practi aci i r first SWPP Plan in 2003 art
updated several times till 2013. A new construction had start in 20T4 and completed
mid to late 2015. Per the direction of NC DEMLR, no amendments were made to the SWPP
Plan and no stormwater sampling was performed during this construction period.
Stormwater from e i runs io one outfall (Outfall-001) located on the northwest corner of
the facility. The drainage areas contributing to the stormwater discharge includes: galvanized
metal roof building (main manufacturing building), galvanized fence around the facility,
parking lot on the east side of the facility, concrete pavements on northern and southern sides of
the facility, pervious area on the northern side of the facility and two cooling tower sprays (if
any). Typical items stored outside the manufacturing building that are exposed to stormwater
are: finished chillers ready to be shipped to the customers, wooden pallets and boxes,
galvanized metal frames for the erecting chillers, and other steel pieces required for the
manufacturing_ In addition, due to increase in production, the facility is experiencing heavy
truck traffic on the facility grounds. Further, majority of the facility is surrounded by a
galvanized fence.

As per the NPDES General Stormwater permit requirements, Carrier had collected several
stormwater samples at the outfall in the past years and it is our understanding that the facility
had some occasional hits on Zinc (Zn) and Copper (Cu) above the benchmark levels in the
collected stormwater samples. To understand the sources for Zn and Cu, Carrier had performed
several stormwater samples from various locations throughout the plant in 2013 and 2014.
Based on the analytical results, Carrier understood that the stormwater samples collected from
roof gutter discharges and air conditioning units contributed to the increase of Zn and Cu levels
above the benchmark levels in the stormwater. Since the hits were occasional, minor
mitigations for Zn and Cu were performed at the site. The mitigations completed at the site
include: roof over the open copper trimmings container, move galvanized steel frames from the
western side of the facility to eastern side of the facility and keep activated carbon drums on 10
building downspouts.
The stormwater sampling had resumed in 2015 (2id sampling event) and continued in 2017 and
2018. The latest sample results are as follows:

NOTE,: *Permit Automatically Renewed for 1 year on Oct 31, 2017 to Oct 31, 2018
Based on the above analytical test data, the facility had exceeded the benchmark levels for
Copper in the last four consecutive sampling episodes and two times for Zinc. However, please
note the permit expired on October 31, 2017 and according the State web site, it is our
understanding that the permit automatically renewed to October 31, 201K. Based on the new
permit, the facility had exceeded only two sampling episodes consecutively above the
benchmark levels for copper during the permit period. Therefore, Carrier shall follow the Tier 2
and not Tier 3 sampling protocol going forward.
Tier 2 is applicable If During the term of this permit, the first valid sampling results from two consecutive
monitoring periods air above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfolL
Tier 3 is applicable If. During the term ojthis permit, ifthe first valid sampling results required for the permit
monitoring periods exceed the benchmark value, or are outside the benchmark range, for any ,specific parameter at
arty specific ortrfell on four occasions, the permittee shall notify the DWQ Regional Office Supervisor in writing
within 30 days of receipt of she fourth analytical results.
5.0 Strateev to Mitigate Zinc and Copper in Stormwater Discharge
Based on the last sampling results reported in January 2018, Carrier had implemented several
administrative controls to mitigate the Zn and Cu levels in the stonnwater. The engineering and
administrative controls implemented in the last 60 days are as follows:
• On the southern yard of the facility, several pieces of equipment, metal sheets, bars,
steel, storage racks, galvanized metal frames (needed for erecting the final unit) were
stored. Carrier had recognized the storage of these materials to the proximity to the
stormwater outfall and disposed of some old materials and moved some out to the
northern side of the building to give buffer time for the stormwater flow to reach the
outfall.
• From the past stormwater sampling studies, Carrier had recognized that the metal roof
(350,000 sft) was a main contributor for Zn and Cu levels in the stormwater discharge.
Therefore, the facility had installed activated carbon units on 11 strategic downspout
locations at the plant to mitigate Zn and Cu concentrations from the metal roof
discharge.
• A stormwater pipe connects parking lot drainage area to the southern side discharge
point and Carrier had hired a vacuum truck to vacuum, approximately 300 feet, sediment

CPEES fMjcrr Nn, 1087-021

accumulated in the stormwater drain coming from the parking lot to reduce the parking
lot impact on the Zn and Cu levels in the stormwater.
• An open blowdown discharge pipe from the cooling tower located on north of the
building was discovered and Carrier had converted the discharge pipe into a closed loop
system so that no blowdown could contribute to the stormwater discharge.
• Carrier had retained a sweeping truck to clean the yard so that dust coming from the
vehicular traffic, which could be contributing to the Zn and Cu levels in the stormwater,
is reduced.
• Based on the wipe tests, a construction trailer found at the site contained high amounts
of Zn and Cu levels moved to the front of the facility and located on a gravel area.
• The empty boxes containing copper tubing are disposed of immediately upon usage.
Carrier strives very hard to be complaint with all the Federal. State and local regulations and
therefore, Carrier wants to place a strategy to evaluate and mitigate the presence of Zn and Cu
in the facility stormwater discharge going forward.
No storxnwater samples were taken since implementing the above administrative controls.
However, Carrier is diligent to aggressively pursue this Zn and Cu issue at the facility and
therefore, retained a Consultant, CP Engineering and Environmental Solutions (CPEES), to
review the current operations and provide a cost effective solutions for our facility that would
mitigate the Zn and Cu issue in our stormwater discharge.
The tasks proposed by CPEES to mitigate the Zn and Cu issues are:
• Review all the current operations to understand possible Zn and Cu contributing
sources to stormwater discharge;
• Collect stormwater samples from strategic locations throughout the plant including
building gutters and analyze them for Zn and Cu;
• Collect and analyze (Zn and Cu) water samples from air conditioning and cooling
tower units that are being discharged to the stormwater discharge;
• Collect dust samples from the yard to see if any Zn and Cu present due to vehicle
activity;
• Review literature for possible sources for Zn and Cu in the stormwater discharge;
• Based on the analytical results, discuss with the State to increase the Benchmark levels
for Zn and Cu for Carrier;
• Review possible engineering and administrative controls that could mitigate Zn and Cu
going to the stormwater outfall;
• Provide a cost-effective solutions to the Zn and Cu issue at the facility;
• Propose a pilot study to verify the effectiveness of the treatment; and
• Complete a Report, describing field activitieg, engineering and administrative controls
recommendations, and possible meetings with the State

Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 11 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at httpJ/h2o.enr.state-ne.us/su/stormwater.htm]
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548
