B No. No groundwater or surface water standards were exceeded.
Yes, a notification of values exceeding a groundwater or surface water standard is attached. It includes a list of groundwater and surface water
monitoring points, dates, analytical values, NC 2L groundwater standard, NC 2B surface water standard or NC Solid Waste GWPS and
preliminary analysis of the cause and significance of any concentration.
Q Yes, a notification of values exceeding an explosive methane gas limit is attached. It includes the methane monitoring points, dates, sample
values and explosive methane gas limits.
Certification
To the best of my knowledge, the information reported and statements made on this data submittal and attachments are true and correct.
Furthermore, I have attached complete notification of any sampling values meeting or exceeding groundwater standards or explosive gas
levels, and a preliminary analysis of the cause and significance of concentrations exceeding groundwater standards. I am aware that there
are significant penalties for making any false statement, representation, or certification including the possibility of a fine and imprisonment.

July 2023 Monthly CAP Report
Dear Ms. Drummond:
Mecklenburg County conducted monthly corrective action plan monitoring at the closed
Holbrooks Road Landfill on July 21, 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 removal of water from the gas system has improved performance
and restored the vacuum to the gas wells. 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 [e-mail] or (980) 3 14-3 85 5 if you have
any questions regarding this report.
Sincerely,
Amber R. Grzymski, P.G.

*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.
