(1) The concentration of the constituents that were not detected is assumed to be zero.
(2) Methane and non-methane emissions are calculated using 98% efficiency.
(3) The concentration of Non-methane hydrocarbons is calculated by subtracting hydrogen, nitrogen, other inorganic substances and methane from 100%.
(4) Fuel non-methane portion molecuar weight calculation is provided in Table 3.
