RE: Landfill Gas Monitoring Report
1st Quarter Sampling Event of 2023
Granville County — Butner Closed MSW Landfill
Permit # 39-02
Dear Ms. Drummond:
Attached please find the Landfill Gas Monitoring Log and Gas Probe Location Map for the 1 st quarter monitoring
event that occurred on February 24th, 2023, at the Granville County Butner Landfill (Permit number 39-02) for
inclusion in your records. Methane was detected in GP-4 above the LEL during this event. Methane was detected in
GP-5, but below the LEL during this event.
No action is recommended at this time. No other locations indicated explosive gas concentrations in excess of the
associated action levels. Additionally, hydrogen sulfide was not detected in any monitored location during this
event.
Landfill gas monitoring will continue on a quarterly basis for the Butner Landfill. If you have any questions, please
do not hesitate to call me at 919-792-1904.
Sincerely,
Garrett & Moore, Inc.

Reporting Form
Notice: This form and any information attached to it are "Public Records" as defined in NC General Statute 132-1. As such, these documents are
available for inspection and examination by any person upon request (NC General Statute 132-6).
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).
Send the original signed and sealed form, any tables, and Electronic Data Deliverable to: Compliance Unit, NCDENR-DWM, Solid Waste
Section, 1646 Mail Service Center, Raleigh, NC 27699-1646.

Notification attached?
e 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.
© 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.
