Division of Waste Management - Solid Waste 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.

preliminary analysis of the cause and significance of any concentration.
x❑ 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.

Attention: Ms. Jaclynne Drummond via email: [e-mail]
Reference: Methane Monitoring — March 28, 2022
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 March 22, 2022 at the closed Sorrell Landfill located in Apex, North Carolina. The attached table
summarizes the methane readings collected at the Sorrell Landfill from January 2008 through March 2022.
The March 2022 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.
The methane concentrations recorded during the March 2022 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
three sampling locations.
Sincerely,
S&ME, Inc.
