METHANE MONITORING RESULTS — FOURTH QUARTER EVENT FOR 2021
WI HIGH POINT CONSTRUCTION AND DEMOLITION LANDFILL AND RECLAMATION FACILITY, PERMIT
NO.41.16
Dear Joe,
Attached are the results from the October 21, 2021, quarterly methane monitoring at the above -referenced facility
for your files. As shown on the attached Landfill Gas Monitoring Data Form, methane was detected above the
lower explosive limit (LEL) at landfill gas monitoring probe LFG-2A. Methane was not detected in any other
monitoring points during the event.
A Landfill Gas Remediation Plan (LFGRP) was submitted to the North Carolina Department of Environmental
Quality (NC DEQ) by Smith+Gardner on July 26, 2021 and was approved by the NC DEC) on August 2, 2021. As
proposed in the LFGRP, the installation of vent in the berm adjacent to LFG-2A and re -grading the area to
promote better drainage began on July 23, 2021. Golder installed two additional vents in the vicinity of LFG-2A
on September 13, 2021. If you have any questions or concerns, please contact us at 336 852-4903,
Sincerely,
Golder Associates NC, Inc.
