3.2 Landfill Site #2 3.2.1 Control Cell 3.2.1.1 February 24 ORS measurements were collected in the control cell during the afternoon of February 24. A schematic of the ORS measurement configuration from this cell can be found in Figure 2-4. Figure 3-4 presents a summary of the actual measurement configurations used in the cell, as well as the measurement results. The figure depicts the average calculated methane flux values along each VRPM measurement plane. The blue arrow depicts the prevailing wind values during the time of the measurements. Figure 3-4 Summary of ORS measurements conducted on Feb. 24 in the control cell of Site #2 The figure shows that the prevailing winds were from the southeast during the time of the measurements. Based on the prevailing wind direction, the southern and eastern VRPM planes are located upwind of the actual landfill cell, so flux values measured along these VRPM planes represent methane emissions from the southern and eastern slopes of the cell (by convention of the measurement method, flux values from measurement planes located upwind of the landfill cell are shown as negative values). The VRPM planes located along the northern and western boundaries of the cell are downwind of the landfill cell (by convention, flux values from measurement planes located downwind of the landfill cell are shown as positive values). The methane flux values measured along the northern, eastern, southern, and western VRPM measurement planes were 14, 7.8, 20, and 2.8 grams per second, respectively. The difference between the sum of the fluxes measured along the northern and western planes (17 g/s) and the 3-20
