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

RE: METHANE MONITORING RESULTS — SECOND QUARTERLY EVENT — MAY 2019
ROWAN COUNTY LANDFILL, PERMIT NO. 80-03
ROWAN COUNTY, NORTH CAROLINA
Dear Jackie,
Attached are the results from the May 1, 2019, quarterly methane monitoring event conducted at the above -
referenced facility. No methane gas was detected in the facility structures during this monitoring event.
Permanent explosive gas monitoring devices are located in the scale -house and maintenance building. Methane
gas was not detected in compliance or assessment monitoring points at concentrations above the lower explosive
limit (LEL, i.e., 5% methane by volume) during the second quarterly methane monitoring event.
The next monitoring event is tentatively scheduled for July 2019. If you have any questions or concerns, please
contact us at 336 852-4903.
Sincerely,
Golder Associates NC, Inc.
