CONSTRUCTION COMPLETION REPORT — SOLAR SPARK INSTALLATION - CLOSED MOORE COUNTY
MSW LANDFILL, PERMIT NO. 6301 -MSWLF-1 979 — MOORE COUNTY, NORTH CAROLINA
Dear Jackie:
On behalf of Moore County, Golder Associates NC, Inc. (Golder) is pleased to submit this construction completion
report associated with the recent installation of two (2) solar spark passive landfill gas flare units at the closed
Moore County municipal solid waste (MSW) landfill, NC Solid Waste Permit (NC SWP) # 63-01. The installation
of the solar spark passive gas flares was first proposed in a Landfill Gas Remediation Plan (LFGRP) addendum
dated December 20, 2019 in response to lower explosive limit (LEL) exceedances in the methane compliance
point MW-15. The LFGRP addendum was approved by the NC Department of Environmental Quality (DEQ) in a
letter dated January 2, 2020. In accordance with the plan, the solar spark landfill gas flare units were to be
installed within 60 days of the next LEL exceedance at landfill gas compliance monitoring point MW-15. The plan
addendum proposed that the solar sparks be installed on the two (2) landfill gas vents associated with the landfill
gas cut-off trench, which was completed in November 2018.
On February 17, 2020, during the first quarterly landfill gas compliance event the LEL was exceeded in landfill gas
compliance point MW-15. Following the exceedance, Golder was contracted by the County to purchase and
implement the installation of two (2) solar spark passive flare units as proposed in the December 20, 2019 LFGRP
addendum and approved by NC DEQ. The units were obtained from EPG Companies and inspected by Golder
prior to installation. The inspection was conducted to ensure each unit was equipped with all parts required for
installation and appeared to be in good operating condition following shipment. Golder mobilized to the Moore
County landfill on April 16 — 17, 2020 to complete the installation of the solar flare units. Both units were installed
without issue and passed the pre -operation checks recommended by the manufacturer prior to operation. Figure
1 which illustrates the location and includes a photograph of each newly installed flare units for your reference.
Quarterly monitoring will continue to help determine the effectiveness of this remedy.
We appreciate your assistance with this project. If you have any questions or concerns, please contact us at 336-

LANDFILL GAS VENT FLARE

CF-5 Solar Spark -
Important! Read all instruction and review
assembly pictures before starting installation.
Check gas flow and quality to assure satisfactory flare performance. Gas quality
should be between approximately 30% and 80% methane and flow at a rate of 2
to 90 CFM at an inlet pressure between approximately 0.5 to 5 inches water
column. Clearly visible waves of exiting gas usually indicate sufficient flow and
pressure.
CAUTION! ALWAYS CARRY A METHANE -IN -AIR SAFETY ALARM
METER while working near landfill gas. Explosive and flammable conditions
may cause injury or death. Do not cause a spark or flame in the presence of
ambient flammable gas concentrations.
CAUTION! This appliance weighs approximately 95 lbs. Vent riser must be
sturdy enough to support flare during windy conditions. Guy wires may be
required.
CAUTION! The solar igniter produces a high -voltage sparking current. Do not
tough metal spark strap or SparkPilotTM while unit is operating; an electrical
shock could result.
CAUTION! This work must be performed only by skilled technicians in
accordance with OSHA regulations and standard industry safety practices.

Installation Instructions
GENERAL NOTE: Pipe thread sealant (pipe dope) is provided and should be used at all
threaded joints.
1. Well or vent riser should be cut approximately 24" above ground level. Install flange
adapters as necessary to mate with 4" inlet bushing at flare base. All connections must
be gas -tight and leakproof. (pic. 1)
2. Bolt the igniter mounting bracket and mounting plate onto the companion flange facing
in a southerly direction. (pic. 1)
3. Mount stainless steel valve on top of 1 ''/z" dia. pipe section with four -inch bushings at
base. Four inch inlet bushing threads into companion flange. Close valve after pipe
assembly is mounted into flange bushing. (pic. 2, 3)
5_1
l�
11

4. Connect the other 1 '/2" dia. pipe section (with the welded guy wire bracket) to the heat
shield coupling which connects to the flarehead. (pic. 4)
5. Install the SparkPilot into the 7/8" slot at the upper rim of the flarehead; make sure
drainage slots in SparkPilot body are facing downward. The black arrow on the
SparkPilot face electrode points in the upward direction. Install spark strap (bend as
shown) from SparkPilot to insulated pipe clamp. Then install this entire assembly
(flarehead, heat shield, pipe) into the valve. (pic. 5, 6)
6. Tighten all pipe connections and position the SparkPilot 90' (crosswise) to the
prevailing wind direction.

7. Mount the fully charged solar flare igniter on the two projecting mounting screws.
These screw heads fit into the holes in the back of the igniter case, and the unit slips
slightly downward into the mounting slots. Do not attempt to tighten mounting screws
or disassemble igniter unit.
Attach the eyelet end of the 6' ignition cable (yellow end) to the bottom of the spark
strap. Connect the other snap -on end of the ignition cable to the hot line terminal
(beneath white ceramic insulator). The rubber boot will cover the bottom of the white
ceramic insulator. Coil and secure any excess cable. (pic 10, 11)
Connect one eyelet of the 2' ground cable to the ground
terminal on the front of the igniter box. Connect the other
end of the ground cable to the nearest fastening bolt at
rear of mounting plate. An extra nut and washers are
placed on this bolt for connecting the eyelets. Also
connect an eyelet of the 5' ground cable to the same bolt.
Both eyelets should be fastened beneath the double
washers and then tighten the terminal nut. BE SURE
TO INSTALL GROUND CABLE INSIDE OF
POSITIVE LOCKING WASHERS TO ENSURE
GOOD GROUND CONNECTION. (PIC 8,9)

10. Push the grounding stake into the soil near the riser pipe, within reach of the 5'
grounding cable. Connect the other eyelet of the 5' grounding cable to the bolt at the
top of the grounding stake. Coil and secure any excess cable.
11. After checking completion and security of all above steps, open gas valve and let the gas
purge the system for a few minutes.
12. Turn "ON" switch of solar igniter and listen for "snapping" sound of a spark plug.
Verify that red spark indicator light is flashing. Flare should ignite within 60 seconds.

Trouble Shooting
IF FLARE DOES NOT IGNITE, the problem could be:
1. Insufficient gas flow
2. Poor wiring connection
3. Low voltage from battery
4. Defective spark pilot
5. Defective igniter box
TO DIAGNOSE PROBLEM
FIRST, CLOSE GAS VALVE; then follow instructions below:
A. Verify spark is occurring. Check SparkPilot gap (0.045" to 0.050") and visually
inspect spark. You will see a flash across the gap and hear a snapping sound. DO
NOT TOUCH SPARKPILOT OR SPARK STRAP TO AVOID ELECTRICAL
SHOCK. If there is NO SPARK, follow B. If there IS SPARK, follow C.
B. Test voltage on the ignition cable. If you do not have a voltage tester you can bridge
from positive to negative on the igniter box, and look for spark.
1. If you DO NOT have spark at the igniter box you have either a drained battery,
or a defective inner seal box. Contact EPG technician.
2. If you DO have spark at the igniter box you have either a poor connection to
the SparkPilot, or a defective SparkPilot. Contact EPG technician.
C. Open valve very slowly to check for "rich" condition. Flare may ignite at partial
open setting. Experiment with a few trial settings. If flare does not light, follow D.
D. TURN OFF SPARK IGNITER, then, verify gas quality with meter. If gas
quality is between 30% and 80% methane, follow E.
E. Close gas valve; make sure spark igniter is "OFF"; then: Readjust Spark Pilot
vertical location or radial position to optimize ignition with flow rate and prevailing
wind. Return to Step 12.
If problems persist, contact EPG technicians at [phone] for help with
unresolved questions or problems.
