Re: Tier Three Action Plan for Copper and Zinc Benchmark Exceedances
Trane U.S., Inc., 4500 Morris Field Drive, Charlotte, NC 28208
Stormwater Certificate of Coverage Number NCGO30098
Dear Mr. Basinger:
Trane U.S., Inc. (Trane) owns and operates the HVAC equipment remanufacturing facility (Facility) located at
4500 Morris Field Drive, Charlotte, NC. Trane is authorized to discharge stormwater associated with industrial
activities via Certificate of Coverage No. NCG030098 issued by the NC Department of Environmental Quality
(DEQ) under Stormwater Metal Fabrication General Permit Number NCG030000 (Permit). The Permit is effective
July 1, 2021.
Based on our October 2021 stormwater monitoring results received on November 3, the Facility has four sampling
results above the Copper benchmark within the term of the Permit. This triggers Tier Three response status for
the Facility per Section E-7 of the Permit. While the Facility is currently at Tier Two status for Zinc, Trane has
chosen to implement a Tier Three response for Zinc given three consecutive benchmark exceedances have
occurred. This letter serves as Trane's proposed Action Plan for the Regional DEQ Office to review and approve.
The Action Plan summarized in this letter is supported by the following attachments:
Attachment 1: Stormwater Monitoring Results for Copper & Zinc for July through October 2021.
Attachment 2: Industrial Activities Inspection Report
As communicated in our recent benchmark notification letter to DEQ, Trane has experienced an ongoing challenge
with the Copper and Zinc benchmarks as documented in monthly Discharge Monitoring Reports going back many
years. Past investigative studies suggest rain falling on the Trane property contains measurable concentrations of
Copper/Zinc, in some cases at or near the benchmark values. We recognize that other Trane site factors may also
contribute to the elevated stormwater concentrations. Pursuant to Section E-7(b) of the Permit, Trane is required
to include six (6) specific elements in the Action Plan as detailed below.
Element J: Documentation of Benchmark Exceedances. The following table summarized the stormwater
monitoring results above benchmarks for Coper and Zinc since the Permit effective date. Attachment 1 includes
the stormwater monitoring laboratory reports for July through October 2021.

Page 2 of 3 December 2, 2021
Element 2: Inspection Report of Industrial Activities. Following receipt of laboratory results indicating
benchmark exceedances, Trane staff completed stormwater management inspections to identify and evaluate
possible causes of the benchmark exceedances. Trane has not identified specific industry activities that are the
root cause of the exceedances. Trane began in September an effort to sample stormwater at various sources
upstream (prior to the outfalls) to look for industrial activities that may be contributing Copper and Zinc. Trane
recently engaged an external stormwater expert (Mr. Mark Van Auken, Arcadis) to assist to identify site factors or
conditions contributing to the elevated Copper and Zinc monitoring results. Mr. Van Auken conducted a site
inspection on November 19, 2021. A copy of the inspection report is included at Attachment 2. The inspection
of industrial activities occurring within the stormwater drainage area did not identify any obvious root cause for
the elevated results. Arcadis agrees with Trane's strategy to conduct the investigative stormwater testing at various
site locations within the outfall drainage area.
Element 3: Evaluation of Standard Operating Procedures and Good Housekeeping Procedures. Trane has
completed an initial review of SOPS and housekeeping to determine if operational practices or any housekeeping
challenges are contributing to the benchmark exceedances. The Trane review included areas and activities that
may impact stormwater discharges including current manufacturing processes, storage practices, housekeeping
measures, training procedures and other relevant operations. Trane has identified potential process improvements
including switching of sand blasting materials to reduce waste and providing cover or moving equipment
susceptible to rainfall to reduce potential exposure of industrial activities to stormwater.
Element 4: Identification ofSource(s) ofExceedances. The Facility inspections and procedures evaluation have
not identified the sources of the benchmark exceedances. Trane completed initial sampling of stormwater at
various points within the drainage area. We have been challenged to complete multiple tests due to limited rainfall
for the Charlotte area. Our preliminary results show the following:

ND = non -detect; N/A = not applicable, unable to collect water samples.
The data under "Non -contact Rainwater" represents rainwater collected in an open pail at the Facility before the
rainfall is impacted by Trane industrial activities. This data suggests that rainwater falling on the Trane property
has elevated concentrations at it arrives at the Facility. We suspect that these elevated ambient Copper and Zinc
concentrations are likely originating as airborne particulate from other properties in the region. We recognize this
is a small data set and additional sampling is necessary to develop a clearer picture of the non -contact rainwater
and the impact to stormwater from the various areas of the facility.
Trane proposes a 6-month period to allow additional site sampling in parallel to our monthly Tier Three compliance
monitoring for DMR reporting. This period would span December through May 2022. Our goal is to collect
samples for three measurable storm events over this 6-month period. This timeframe should be sufficient for the
additional samples to be collected during our normal work hours (day shift, Monday through Friday). Our
upstream sampling strategy will include:

Page 3 of 3 December 2, 2021
• Non -contact rainwater sampling to use as a baseline.
• Sample collections from downspouts at the Facility buildings to determine if roofing materials are
contributing sources.
• Sampling site drainage ditches/swales and storm sewer chambers where possible.
• Limited analytical tests for Total and Dissolved Copper and Zinc to determine if the metals can be
substantially removed by filtration and thus better define the type of BMP that could be used for future
treatment if warranted.
• Obtaining additional samples and/or adding sampling locations if there is potential for run-on to the Trane
facility from other neighboring properties.
Trane has attempted to screen DEQ's Stormwater Program Laserfiche Repository to determine if other sites near
the airport are experiencing similar benchmarks challenges. We are finding it difficult to identify neighboring
sites to assess. We would appreciate if the DEQ would provide metals sampling results for industrial facilities
near Trane facility and/or share if other regional facilities are experiencing similar exceedances metals benchmarks
challenges.
Element S. Specific Actions to Remedy Identified Sources. Based on the sampling program results described
under Element 4, Trane will assess reasonable onsite measures to implement that will improve the site's direct
impact on stormwater through administrative and/or engineering controls. These may include improved
housekeeping measures, revised exterior storage practices, improved team member training, other materials
management practices to be defined, general source mitigations, or structural best management practices. Specific
actions will balance Trane's impact to stormwater vs the condition of rainwater that falls onto the Facility.
Within 30 days of receipt of the analytical results from the third measurable storm event analyzed, Trane will
submit a report to DEQ that provides the results of the investigative testing and our proposals to mitigate the
elevated Copper and Zinc conditions associated with our direct industrial activities. We suggest a meeting
thereafter with DEQ to review the data, the proposed mitigation measures, and our timeframe to adopt the
mitigation measures.
Element 6., Monitoring Plan to Verify Effectiveness of Action Plan. Trane anticipates that the follow-up
monitoring plan will consist of monthly DMR testing for all parameters until three samples in a row are below
benchmark values, while considering the effect of other contributing source(s). We welcome DEQ's perspective
on a reasonable remedy to address the contributing source(s). The effectiveness check may include structuring a
monitoring plan to verify effectiveness of the Action Plan or changing monitoring requirements if non -
manufacturing sources or offshe sources are determined to be the primary cause of the exceedances. It may also
include writing enhanced stormwater measures into the facility's permit to better address the exceedances. A
schedule for completing final actions required will be developed in concert with DEQ.

Arcadis recently performed a routine site inspection of the Trane Charlotte Raman facility on November 19, 2021
in accordance with Part 3.1 of the 2021 MSGP and Part E-7 (b) ii of General Permit No. NCG030000. The primary
focus of the inspection was identifying potential sources, including facility industrial activities, and their impact on
stormwater runoff within the drainage areas of the regulated ouffalls with known exceedances of Copper and Zinc.
A summary of the inspection results is provided below and in the attached inspection form. While we did observe
some equipment and activities that could expose industrial materials to stormwater, in general we feel the facility
is well -managed and the inspection did not identify any obvious root cause for the elevated results.
As part of the inspection process Arcadis discussed areas and activities that may impact stormwater discharges.
It is our understanding that Trane is developing an Action Plan that includes identification of potential process
improvements to reduce waste and housekeeping measures to reduce potential exposure of industrial activities to
stormwater. Trane staff has also performed initial sampling that suggests rainwater falling on the property and
other non -facility operations could be contributing to the exceedances and proposes a 6-month period to gather
additional sampling data in parallel to monthly compliance monitoring to identify sources of the exceedances and
potential enhanced stormwater measures that could be implemented to better address the exceedances. Arcadis
strongly agrees with Trane's strategy to conduct an expanded investigative stormwater testing program.
Inspection Results
The routine site inspection of the Trane Charlotte Reman facility performed on 11/19/21 included the following:
Inspection Personnel. Qualified personnel performed the inspection. They included Mark Van Auken, PE,
CPMSM, ENV SP, Stormwater Practice Leaderfor Arcadis and Carrie Nguyen, Trans EHS Manager. The
inspectors discussed recent results of visual and analytical monitoring before the inspection to allow for
proper planning and conducting of the inspection process.
Areas Inspected. The inspection personnel conducted inspections of the entire facility, including areas of the
facility where industrial materials/activities are exposed to stormwater, areas identified in the facility's SWPPP
as potential pollutant sources, site discharge points, and stormwater control measures. Observation were
recorded in a Trane Facility Stormwater Inspection Report Routine Inspection Form (see attachment). The
facility did not have any significant spills or leaks within the past three years, so these areas did not need to
be observed.

Items Observed. During the site inspection, the inspection personnel examined industrial materials, residue
or trash that may have or could come into contact with stormwater; leaks or spills from industrial equipment,
drums, tanks and other containers; offsite tracking of industrial or waste materials, or sediment where vehicles
enter or exit the site; tracking or blowing of raw, final or waste materials from areas of no exposure to exposed
areas; erosion of soils at the facility, channel and streambank erosion and scour in the immediate vicinity of
discharge points; non -authorized non-stormwater discharges; control measures needing replacement,
maintenance or repair; and the discharge points themselves. In general, the facility is well -managed and the
inspection did not identify any obvious root cause for the elevated Copper and Zinc levels.
• Facility Inspection Documentation. This report serves as documentation of findings of the facility inspection
and should be maintained with Trane's SWPPP as well as submitted with the Action Plan in compliance with
the requirements of Part E-7 (b) ii of General Permit No. NCG030000. The following information is included in
the attached inspection forms:
• The inspection date and time;
• The name and signature of the primary inspector;
• Weather information;
• Observations relating to plant operations, practices and stormwater control measures at the facility; and
Any incidents of noncompliance.
Additional stormwater control measures needed to comply with the permit requirements will be identified in the
near future as part of the proposed Plan of Action. A statement, signed and certified in accordance with Appendix
B, Subsection 11 will also be prepared at that time.
If you have any questions or need further information regarding our site inspection, please contact us.
Sincerely,
Arcadis G&M of North Carolina, Inc.
