Instructions:
Prepare one form for each individually monitored unit.
Please type or print legibly.
Attach a notification table with values that attain or exceed NC 2L groundwater standards or NC 2B surface water standards. The notification
must include a preliminary analysis of the cause and significance of each value. (e.g. naturally occurring, off -site source, pre-existing
condition, etc.).
Attach a notification table of any groundwater or surface water values that equal or exceed the reporting limits.
Attach a notification table of any methane gas values that attain or exceed explosive gas levels. This includes any structures on or nearby the
facility (NCAC 13B .1629 (4)(a)(i).

Subject: Holbrooks Road Landfill Permit 60-02
April 2023 Monthly CAP Report
Dear Ms. Drummond:
Mecklenburg County conducted monthly corrective action plan monitoring at the closed
Holbrooks Road Landfill on April 25, 2023, in accordance with the approved corrective action
plan 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, HP- 18R, HP-24, HP-25, HP-26 and HP-27), nine (9) trench vents (MV-1, MV-2, MV-3,
MV-4, MV-5, 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 active system currently is not functioning properly. It appears
that water has gotten in the system and is reducing the vacuum on the gas wells. Service on the
system has been requested. The valve on probe HP-9 is fully open and has been since the
modifications were complete on February 18, 2022. The valve will remain open to vent the
landfill gas in this area.
Please contact me at amber.grz mski@mecklenbur cg ountync. ov or [phone] 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.
