GENIVAR 1 Q116300-101
1. INTRODUCTION
Waste Management of Canada Corp. has given a mandate to GENIVAR S.E.C. for the
assessment of methane emission at the surface of Ottawa landfill.
According to the offer for professional services, the following tasks were performed :
Measurement on a continuous basis of the methane concentrations in the
ambient air above the surface of the landfill site and the air sparging system with
the FID-GPS technology developed by the firm GENIVAR S.E.C. ;
Measurement on a continuous basis of the methane concentrations in the
ambient air above the ground along four (4) extra lines, located on the north and
south sides of the landfill site, with the FID-GPS technology developed by the
firm GENIVAR S.E.C. ;
Data processing and mapping of results ;
Technical report editing.
Field work was performed by Mr. Dave Veilleux and Mr. Alexandre Monette of
GENIVAR S.E.C. on April 22 & 24, 2009.

2. METHODOLOGY
2.1 Location of measurements
Assessment of vertical migration of LFG was performed above the entire landfill and
above the ground along four (4) extra lines located on the north and south sides of
the landfill site. Location of the measurement points is shown on Figure 2-1.
This assessment was also performed above the LFG air sparging system trench (2 lines
of 1 km long at a height of approximately 6 inches on each side above ground).
Location of the measurement points is shown on figure 2-2.
2.2 Methodology
Methane concentrations above ground are measured and recorded on a continuous
basis with a portable Flame Ionisation Detector (FID). Spatial location of the
measurement points are defined and recorded by a Global Positioning System (GPS).
According to the EPA procedure, the sampling is done along the periphery of the
waste cells and along a serpentine pattern spaced about 30 meters apart, at a height
of approximately 6 inches above ground.
Methane concentrations are then processed and spatial coordinates are transformed
from the degree, minute, second format to the NAD83MTM Zone 9 system. A map
showing iso-contours of methane concentration is prepared. The iso-contours are
overlaid on a map showing the landfill gas collection system general arrangement in
order to be able to evaluate its efficiency and to identify areas where modifications
are required to reduce emissions to the atmosphere.
2.2.1 Instrumentation
Methane concentrations are determined with a Thermo Environmental Instruments
TVA 1000B portable analyser by the flame ionisation method. This instrument is used
for the measurements into ambient air of small concentrations of total volatile organic
Landfill gas emission surface sampling Ottawa Landfill
GENIVAR 3 Q116300-101
compounds, expressed as methane. The analytical range of the analyser is 0 to
50 000 ppmv with a lower detection limit at 0.5 ppmv.
Since the concentration of methane in landfill gas is more than 100 times higher than
non methane organic compounds and that the measured concentrations are low, the
result given by the instrument is interpreted as methane alone.
Spatial co-ordinates are measured by a Garmin GPS which in DGPS mode has an
accuracy of less than 1 meter.
Wind speed is checked regularly during sampling with a portable anemometer.
2.2.2 Instrument calibration
Accuracy of the analytical instrument is verified on a regular basis with calibration gas
having a known composition. Adjustments are made if required. For the TVA
1000B, the calibration gases are composed of:
100 ppmv of CH4 in air ; 10 000 ppmv of CH4 in air.
2.2.3 Meteorological constraints
Average wind speed during sampling shouldn't exceed 8 km/hr with maximum peak
speed at 20 km/hr.

3. RESULTS
3.1 Regulations
In Ontario, owners of landfill sites need an approval if their facilities “may discharge
or from which may be discharged a contaminant into any part of the natural
environment other than water » (Environmental Protection Act, R.S.O. 1990,
CHAPTER E.19, part II General Provisions, section 9 Approval of Director, plant or
production process). However, no specific maximum acceptable concentration of
methane above the surface is defined.
Under item No. 4 of Provincial Officer’s Order No. 5830-6Z2PPW, WM is required
to perform landfill gas emission surveys at the Ottawa landfill site in April, June,
August, October and December 2009. Each report shall include also the survey
results of the previous campaign and describe any actions related to the LFG
collection and flaring system taken since the last survey.
US EPA has enacted operational standards in "Standards of Performance for New
Stationary Sources and Guidelines for Control of Existing Sources: Municipal Solid
Waste Landfills", into effect since March 12th, 1996 (40 CFR Parts 51, 52 and 60).
This rule stipulates that methane concentrations measured at the surface of the
landfill shall be less than 500 ppmv. EPA methodology and standard will be used for
the assessment of methane emissions to the atmosphere at the Ottawa landfill.
3.2 Surface sampling results
Results show that there are 27 points (0,38%) having a methane concentration above
500 ppmv compared to 3,60% of the points for the previous survey. Table 3-1
presents the location of those points together with their concentration and table 3-2
presents the results of December 2008 survey.
Figure 3-1 presents the detailed results for this survey and figure 3-2 for December
2008. Iso-contour map of methane concentrations is shown on figure 3-3 for this
sampling campaign and figure 3-4 for December 2008. The highest concentration
Landfill gas emission surface sampling Ottawa Landfill
GENIVAR 7 Q116300-101
recorded in the present survey is 6 582 ppmv at (346 258, 5 015 414) which is
located near of well #18.
High methane emissions are concentrated mainly on the north-east corner, near well
#78 and along the north slope, near well #48.
Figure 3-5 presents the methane concentrations obtained above the LFG air sparging
system located along Carp Road for this survey and figure 3-6 for December 2008.
No methane concentration higher than 500 ppmv was measured in April 2009.

3.3 Site configuration and well performance
As of April 2009 survey, the landfill gas collection system at the Ottawa landfill is
composed of 177 vertical extraction wells and horizontal collectors installed at the
bottom of North, West and South slopes. All of these wells are connected to three
(3) flaring stations (2 enclosed flares with 3 blowers and 1 candlestick flare with 1
blower) via a 450 mm header located at the bottom of the slopes.
3.4 Improvements since the previous assessment
This is a summary of the work that was completed since the last air emission survey
which was conducted in December 2008.
An electrical and piping system was installed on the North, West and South Slopes to
install pumps to dewater the LFG wells. The pumps will be installed in May.
A total of 1,700m of horizontal collector was installed at the base of the North, West
and South Slopes. A total of 16 vertical wells were also installed at the base of the
Northeast Slope.
3.5 Wind speed
Sampling was done when the winds were under specifications described at 2.2.3.
The average velocity of the wind was between 6 and 8 km/hr and the gust of the
wind was 15 km/h on Wednesday (April 22, 2009) and the average velocity of the
wind was between 4 and 8 km/hr and the gust of the wind was 11 km/h on Friday
(April 24, 2009).

4. INTERPRETATION OF RESULTS
The results shown on Figure 3-3 indicate that high emissions are principally located :
1) Along the south slope, near well #18 ;
2) On the north-east corner, near well #78 ;
3) Along the north slope, near well #48.
The integrity of the soil cover should be checked and modified if required and the
vacuum increased at the wells located in the area of the high spots.
No high value was recorded above the ground along the four (4) extra lines located
on the north and south sides of the landfill site and above the air purging system near
Carp road.
