METHANE MONITORING RESULTS -- THIRD QUARTERLY EVENT OF 2020
CLOSED HENDERSON COUNTY LANDFILL, PERMIT NO. 45-01
HENDERSON COUNTY, NORTH CAROLINA
Dear Jackie,
20147157.201
Attached are the results from the September 23. 2020. third quarterly methane monitoring event conducted at
the above -referenced facility. As shown on the attached Landfill Gas Monitoring Data Forms, methane was
not detected above the lower explosive limit (LEL) in any compliance methane monitoring points.
No methane was detected in the facility structures during this compliance monitoring event. If you have any
questions or concerns, please contact us at 336-852.4903.
Sincerely,

Method of Test : The analy2er is calibrated in a temperature controlled chamber using a series of reference
gases, in compliance with procedure ISP17.
The reported expanded uncertainty is based on a standard uncertainty multiplied by a coverage factor of k=2,
providing a level of confidence of approximately 9596. The uncertainty evaluation has been carried out in accordance
with MIST requirements.
