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).

Attention: Ms. Jaclynne Drummond via email: [e-mail]
Reference: Methane Monitoring — August 29, 2023
Sorrell Landfill (Permit No. 92-04)
8000 Smith Road, Apex, North Carolina
S&ME Project No. 1054-07-251
Dear Ms. Drummond:
On behalf of Sorrell Grading Company (Sorrell), S&ME, Inc. (S&ME) is submitting methane gas monitoring data
collected on August 29, 2023 at the closed Sorrell Landfill located in Apex, North Carolina. The September 2023
measurements were collected by S&ME personnel in the on -site permanent methane monitoring wells (probes); in
on -site groundwater monitoring wells; in off -site groundwater assessment wells; and from beneath two off -site
residential structures located at 5100 and 5101 Herndon Lane depicted on Figure 1.
Methane measurements were collected using a Landtec GEM 5000 portable gas analyzer, following Solid Waste
Section guidelines and standard operating procedures previously established for Sorrell Landfill. Table 1
summarizes the methane readings collected at the Sorrell Landfill from January 2013 through September 2023.
The methane concentrations recorded during the September 2023 monitoring event exceeded the operational
limits, established for gas control at municipal solid waste landfills by North Carolina Solid Waste Rules [15A NCAC
13B .1626(4)(a)], i.e. methane concentrations were greater than the lower explosive limit (LEL) for methane (5%
CH4), at one locations (MMW-4).
Of particular note, S&ME observed property to the south of the landfill, west of Herndon Lane was under
development. Photos of the adjacent property are included on the attached photolog.
Sincerely,
S&ME, Inc.
