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).

Re: Landfill Gas Migration Monitoring Report
Surry County Closed Unlined Landfill -Mt. Airy
Event Date(s): March 5, 2020 (Event 1 of 4)
Permit Number: 86-02
Dear Mrs. Montgomery:
Quarterly landfill gas (LFG) monitoring was performed at the Surry County Landfill located in Mt. Airy
NC on March 5, 2020. Municipal Engineering Services Company, P.A. (MESCO) personnel monitored
structures and wells for gas migration. This monitoring event was performed in accordance with the
NCDEQ (formerly NCDENR) Solid Waste Section Landfall Gas Monitoring Guidance Document dated
November 2010. Monitoring was performed utilizing a calibrated Envision gas analyzer and SensorCon
H2S Meter. Gas levels consisting of methane, hydrogen sulfide, oxygen and carbon dioxide were recorded
at seven probes (MGP-2R through MGP-8) and nine structures; results are presented on the data form.
The stabilized methane concentration recorded at MGP-7 was detected above %LEL. This monitoring
location is not at a property boundary. We will monitor results from subsequent events at this location.
The monitoring results summary form, a drawing depicting the monitoring locations and instrument
calibration certificate are attached, and will be accessible at the facility. The next monitoring event should
be performed before July 1, 2020. If you have any questions regarding this report, please contact us by
phone at [phone] or by email at [e-mail].
Sincerely,
MUNICIPAL ENGINEERING SERVICES CO., P.A.
