METHANE MONITORING RESULTS — SEPTEMBER MONTHLY 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 September 20, 2021, monthly methane monitoring at the above -referenced
facility for your files. As shown on the attached Landfill Gas Monitoring Data Form, methane was not detected
above the lower explosive limit (LEL) at any compliance monitoring point.
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 DEQ on August 2, 2001. 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, 2001. Golder installed two additional vents were in the vicinity of LFG-
2A on September 13, 2021 and a report documenting that effort is in progress. If you have any questions or
concerns, please contact us at 336 852-4903.
Sincerely,
Golder Associates NC, Inc.
