1.0 Introduction

This Methane Warning System Installation Report has been prepared by Hart & Hickman, PC
(H&H) to document the installation and post-installation inspection and testing of the methane
warning system installed in the western portion of “Building 2” at the Loftis-Blythe Construction
Brownfields site (Brownfields Project No. 16055-12-060) located at 5518 David Cox Rd. in
Charlotte, North Carolina. A site map is provided as Figure 1. Results of post-construction
methane probe monitoring indicated that a methane warning system was warranted for the
western portion of Building 2. As such, in accordance with the Environmental Management Plan
(EMP) for the site, H&H provided a Methane Warning System Design Plan to the North
Carolina Department of Environmental Quality (DEQ) on May 16, 2017 to monitor for elevated
methane concentrations inside the western portion of Building 2. Following approval from DEQ,
the Methane Warning System was installed at the site. The purpose of this report is to document
the installation and post-installation inspection and testing of the Methane Warning System.

2.0 Methane Warning System Installation
In May 2017, the methane warning system was installed in the western portion of Building 2
currently occupied by JDNA. The installation was conducted in accordance with the Methane
Warning System Design Plan provided to DEQ on May 16, 2017, revised per comments from
DEQ on May 19, 2017, and approved on May 22, 2017. Design specifications are included as
Figure E-1. The western portion of Building 2 consists of an approximate 3,400 square foot (sq
ft) office space and an approximate 41,000 sq ft open warehouse. In accordance with the
approved methane warning system design, a total of seventy-seven (77) GD-2A sensors were
installed in the office and warehouse space. The sensors are installed at a frequency that meet or
exceed the manufacturers recommendation of one sensor per every 900 square feet. In addition
(as requested by DEQ), sensors in the office area were installed in the offices, closets, and a
cabinet in the break room. The locations of the sensors are shown on Figure E-2.

The GD-2A sensor is designed to send an alarm signal to a central control panel in the event
methane is detected above 25% of the lower explosive limit (LEL). The GD-2A is equipped
with a solid-state sensor that does not require calibration, and the expected life of a GD-2A
sensor is 7 to 10 years. The manufacturer specification sheet for the GD-2A senor is included in
Appendix A. At the time of installation, each sensor was tested by manually pressing the “test”
button located on the unit and/or exposing the sensor to combustible gas. All of the sensors
passed the manual test.

In the event a sensor malfunctions or loses communication with the central control panel, a
“trouble” signal will be sent to the panel and a third party monitoring company which will notify
personnel on-site that a sensor has lost communication or needs to be replaced. In the event of a
power loss, the methane warning system will operate on a battery backup installed in the control
panel.

The sensors are wired into eight (8) “zones” inside the facility and tied into the building’s central
alarm control panel. The layout of each zone is shown on Figure E-2. In the event the methane
is detected above 25% LEL, a signal will be sent to the central control panel and the system

alarm will be activated which will prompt an evacuation. The alarm consists of illuminated
strobes and sirens in the office, warehouse space, and entryway of the JDNA space. Once an
alarm is triggered, a notification will automatically be sent a third-party alarm monitoring
service. The third-party monitoring service will then call and notify the on-site contact person
and the property owner contact that an alarm has been triggered. The third-party monitoring
service will also be able to remotely identify the “zone” that triggered the alarm and
communicate the zone of the alarm to the on-site contact person and property owner contact.

Following an alarm, on-site personnel and/or property management (on-call 24 hours) contacts
will notify first responders to clear the building if it is suspected that the alarm was due to
elevated methane. In the event of an alarm, DEQ will be notified within one business day once it
has been verified that the alarm was the result of elevated levels of methane. If two (2) verified
alarms occur within a six-month period, the property owner at that time will submit a plan for
DEQ approval for a methane mitigation system.

3.0 Post-Installation Inspection

On June 2, 2017, the system was inspected by a North Carolina Professional Engineer (PE) from
H&H (Mr. Trinh DeSa) and a PE from Engitecture (Mr. Greg Wiley) to verify that the system
was installed in accordance with the specifications included on Figure E-1 and Figure E-2 and
the design goals of the warning system were met. The inspection generally included visually
locating each sensor, manually testing a representative number of sensors with methane gas,
confirming communication of the sensors with the central control panel, confirming the presence
and operation of the alarm strobes and sirens, confirming that the correct alarm zone was
displayed during an alarm event, and confirming the response from the third-party monitoring
service. At the time of the inspection, the inspectors verified that the methane warning system
was installed in accordance with the approved design. A sealed certification from Mr. Wiley is
included in Appendix B and the seal of Mr. DeSa is included on the front cover of this report.
Photographs of the system installation are included in Appendix C.

4.0 Follow-Up Methane Monitoring and System Testing

In accordance with the approved design, each subsequent year following installation, the
methane warning system shall be checked for performance by manually activating the “test”
button on a representative number of GD-2A sensors and verifying communication with the
sensors from the central control panel. In addition, the system check will include visually
confirming that each sensor’s green “armed” light is illuminated.

In accordance with the approved Methane Warning System Design, the property owner will
continue monitoring of the methane probes on a quarterly basis until December 2018 to evaluate
if methane concentrations continue to increase, stabilize, or decrease with time. In addition to
the methane probes, methane readings will also be collected from inside both site buildings,
sewer manholes on the north side of Building 2 and a drainage trench on the south side of
Building 2 during the quarterly monitoring events. The first monitoring event will be conducted
in June 2017. In addition, as part of the monitoring, unpaved and paved areas will be inspected
for the presence of settlement areas which could be locations of methane gas accumulation and
methane readings will be taken from those areas as well. If settlement areas are observed, the
property owner will be notified to take corrective actions such as filling in holes or repairing
pavement.

Annual monitoring reports of the methane monitoring and the testing of the methane warning
system will be prepared and submitted to DEQ in January of each year concurrent with the
submittal of the annual Land Use Restriction Update (LURU). The annual reports will detail the
following with regard to the methane monitoring:

• results of the methane probe, utility, and indoor air monitoring
• results of the exterior area visual inspections (including corrective actions taken, if any)
• in the January 2019 submittal, a recommendation for continued methane monitoring will
be included (i.e., locations and sampling frequency)

S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-028 5600 Cox Road\Methane Warning System Installation Rpt\Methane Warning System Installation_TCD for PE Stamp.doc
The annual reports will also include documentation of the testing of the methane warning
system:
• documentation of the annual methane warning system testing
• documentation of any alarm conditions and resolutions
• repairs or adjustments made to the warning system

The first annual report will be submitted in January 2018.

Methane Sensor Specification Sheet
Macurco™ Combustible Gas Detector
GD-2A
For use with alarm control panels
Methane and Propane Gas Detection
The GD-2A is a low voltage electronic detector of combustible, heating type gases. The GD-2A is designed forconnection to UL Listed Fire Alarm/Burglary Control Panels. Alarm control panels that work on 12 or 24 VDC canprovide battery backup to the GD-2A detectors. This product is for use in ordinary indoor locations of family livingunits and office workspaces. The GD-2A is intended for installation in buildings in non-hazardous locations suchas residences, retail stores, office buildings, and institutional buildings. This combustible gas detector has beenevaluated by UL for methane (natural gas) and propane (LP) gas. It is NOT designed to detect smoke, fire orcarbon monoxide.
Easy OperationA green LED signifies that the GD-2A is armed. If gas is detected, the Red LEDturns on and the alarm condition relay is activated.
Features• Supervised Sensor• Simple installation and operation• SPDT Alarm and N.C. Trouble Relay• Can be self-restoring or latching• Califoirnia State Fire Marshal Listed• Solid State Electronic sensors: no maintenance or recalibration• Sensitivity tested based on UL 1484 Standard for Residential Gas Detectors• Listed to UL Standard 2075 for the Standard for Safety for Gas and Vapor Detector and Sensors

@ 24 VDC, 65 mA @ 12 VAC, 45 mA @ 24 VAC
• Current (in alarm): 70 mA @ 12 VDC, 35 mA
@ 24 VDC, 100 mA @ 12 VAC, 65 mA @ 24 VAC
• Color: white
• Sensor Maintenance: not required
• Alarm Relay Rating: 0.125 A, 40 V, 3 VA
• Trouble Relay: 0.250 A, 40 V, 10 VA
• Operating Temperature Range: 32° to 120° F
• Alarm Set Point: Per UL 1484, 25% LEL
Installation
The three part plastic case allows the GD-2A to be either surface
mounted or installed over a four-inch square or double gang electrical box, providing a near flush mount.
LocationA GD-2A is usually located in each room (except kitchens or bathrooms) where there are gas appliances or through which gas pipes pass. Do NOT mount the GD-2A in a corner. Do NOT mount the GD-2A in kitchens orbathrooms - alcohol’s, ammonia, cleaning solvents, paint thinner, gasoline vapors, and aerosol propellants(aerosol cans such as hair spray usually contain a combustible gas) may cause alarms. Do NOT mount theGD-2A where the normal ambient temperature is below 32° F (0° C) or exceeds 120° F (50° C). If the gas usedis natural gas (methane) mount the GD-2A on a wall about one foot down from the ceiling. If the gas used is propane (LP), mount the GD-2A on a wall or column one foot above the floor. Use the same spacing as for smokedetectors- 30-foot centers, 900 square feet per detector.
