August 2022 Monthly CAP Report
Dear Ms. Drummond:
Mecklenburg County conducted monthly corrective action plan monitoring at the closed
Holbrooks Road Landfill on August 18, 2022 in accordance with the approved corrective action
pIan dated November 2, 2018. This report details the results of that monitoring event.
Samples were collected from nine (9) landfill gas probes (HP-3, HP-4, HP-8R, HP-9, HP15R,
HP-16R, 1-tP-18R5 HP-245 HP-25, HP-26 and 1-fP-27), nine (9) trench vents (MV-1, MV-2, fV1v
MV-4, MV-55 MV-6, MV-7, MV-8 and MV-9), one on site building (Building), the passive flare
landfill gas system (SYS2) and the active landfill gas system (SYST, GWO1 and GW02).
Results of the landfill gas extraction systems are shown in Table 1. The Landfill Gas Monitoring
Data Form is also attached. The valve that connects the system to HP-15R remains fully opened.
The valve the connects the system to the former passive trench was closed. There was not enough
vacuum on the system with the trench valve open. A request to modify landfill gas probe HP-9 to
a venting probe was submitted to you on February 10, 2022 and approved February 14, 2022. The
modifications to HP-9 were completed February 18, 2022. The valve on HP-9 is fully open and
has been since the modifications were complete on February, 18. The valve will remain open to
vent the landfill gas in this area.
Please contact me at amber. grzymski a,mecklenbur countync.gov or (980) 3143855 if you have
any questions regarding this report.

*The differential pressure measurement should be positive. A negative differential pressure may indicate no gas flow. Negative differential pressure
can be the result of dirt or water obstructing the pitot tube perforations. Overpulling by adjacent extraction wells may also result in negative pressure
being displayed.
