1.0 INTRODUCTION
1.1 Backsround
The City of Albemarle Landfrll (DSWM [Division of Solid Waste Management] Permit #84-01)
is located on Stony Gap Road (SR 1720), in Stanly County, North Carolina (see Figure l). Prior
to operating as a C&D Landfill, the site formerly operated as an unlined Municipal Solid Waste
Landfill (MSWLF) that consisted of two units. The first unit (Unit #l) was closed prior to
October l99l with a24-inch thick final soil cover. The second unit (Unit #2) was closed with an
18-inch thick cohesive soil cap with a permeability of l0-s centimeters per second (cm/sec) and
an l8-inch thick soil erosive layer prior to June 1999 in accordance with the Transition Plan.
The C&D Landfill is constructed and operating on top of the Unit #l MSWLF.
Adjacent to the C&D Landfill, across the unnamed tributary of Jacob's Creek, on the same
contiguous property is the active Subtitle D lined MSWLF. The lined MSWLF is comprised of
two contiguous phases (Phase 1 and 2) which are combined and treated as a single unit for
continuity of the reporting to the SWS. This active MSWLF also operates under DSWM Permit
#84-01 and is also reported herein.
1.2 Gas Monitoring Proqram
The Gas Monitoring Program for the active C&D Landfill on top of the former MSWLF has
included the monitoring of the permanent gas monitoring probes located around the site (lvfP-l
through MP-13; excluding MP-6, MP-8), and both the maintenance and recycling shops.
A series of gas monitoring probes have also been installed around the Subtitle D lined MSWLF
(MP-14, and MP-18 through MP-30) to monitor for explosive gases as required by Title l5A
North Carolina Administrative Code Subchapter l3B Section .1626(4)(aXii) and .1626@)(b)
llsA NCAC r38.t626(4XaXii) and .1626(a)(b)1.
The locations of the gas monitoring probes are shown on the attached Figure l. Together these
two groups of gas monitoring probes and the two shops comprise the current gas monitoring for
the City of Albemarle Landfill.

1.3 Gas Data Collection and Presentation
The percentage of methane gas in air data and hydrogen sulfide gas concentrations within the gas
monitoring probes were measured on May 18, 2016 using a LANDTEC GEM-5000rM gas
monitor. These data were entered onto the SWS forms from the LANDTEC GEM-5000t* gut
monitor and the original copy of these forms is retained as part of the landfill operating record
(see Appendix A).
Methane is explosive at concentrations ranging from 5 percent (%) of methane gas (lower
explosive limit - LEL) to 15 % of methane gas (upper explosive limit - UEL) by volume in air.
Hydrogen sulfide is explosive at concentrations ranging from 4.3 percent (%) of hydrogen
sulfide gas (LEL) to 46%o of hydrogen sulfide gas (UEL) by volume in air. SWS management
guidelines state that explosive gases should not exceed either the LEL (5 % of methane gas in air
and 4,3o/o of hydrogen sulfide in air) at property boundaries or 25 o/o of the LEL (1 .25 o/o of
methane gas in air and 1.08% of hydrogen sulfide in air) in facility structures [154 NCAC
t3B.1626()(a)1.
The gas measurement procedures used for monitoring for explosive gases at this Site follow both
the manufacturer's specihcations for the gas monitor and those procedures outlined in Landfill
Gas Monitoring Guidance datedNovember 2010.
The gas results are summarized in Table 1. The instrument calibration records and the Landfill
Gas Monitoring Data Forms as required by Landfill Gas Monitoring Guidance are included in
Appendix A.

2.0 GAS DATA
2.1 Gas Data Results Summarv
2.1.1 Active C&D and Closed MSWLF
Methane was undetected in ten of the eleven gas probes around the active C&D Landfill and
closed MSWLF. Hydrogen sulf,rde was undetected in all of these eleven gas probes. Neither of
the two shops exhibited the presence of methane or hydrogen sulfide. Methane concentration
was found to be above zero for Gas Probe MP-12 (42.9%) along the southwest perimeter of the
active C&D Landfill and closed MSWLF. The regulatory limit at the compliance boundary or
property boundary is 5Yo of methane in air. However, the purchase of the adjacent property
located west from this methane probe, has moved the property boundary about 900 feet further
southwest from MP-12. Additionally, Gas Probe MP-13 which is located southeast from Gas
Probe MP-12 and is closer to the property boundary, exhibited no methane gas. Also, in the case
of Gas Probe MP-12 the surface water along a drainage feature located within the adjacent
property southwest of this gas probe prevents the migration of gas to the property boundary to
the southwest.
The following briefly describes the historical trend to date for Gas Probe MP-12
MP-12: Methane had been previously detected for the period from July 2007 through
January 2009, during which it ranged from2 to 9o/o of methane gas in air. Methane has
been undetected since April 2009 through to the Fourth Quarter of 2012. To date
methane has been detected above the LEL since the First Quarter of 2013.
No hydrogen sulfide was detected in the monitored gas probes at this site during this quarter.
2.1.2 Subtitle D lined MSWLF
Methane was undetected for all of the gas probes around the active Subtitle D lined MSWLF (see
Table 1).

2.2 Comments
Based on results of recent methane monitoring data for both sites, methane gas concentrations at
the gas monitoring probes closest to the property boundary are below regulatory limits for the
Second Quarter of 2016. Additionally, in the case of Gas Probe MP-12 the surface water along a
drainage feature southwest of this gas probe prevents the migration of gas to the property
boundary to the southwest.
