Point Source Emission Factor Development. Using the results of the point source testing task (Task 3), the ERG team will develop average emission factors for the following emission units: • ▇▇▇▇▇ • Well pads • Lift and line compressor engines • Equipment leaks • Storage tanks • Dehydrators • Pipelines The final sub-categorization of the emission units included in the emission factor development task will be determined in consultation with the City, considering the measured variability in emission rates for each unit type (from Task 3) and the availability of process data on which to base the emission factor (from this task). Depending on availability of data, emission factors may be developed on a temporal basis (pound per hour or pound per day) or an activity basis (pound per thousand cubic feet of gas produced). Additionally, operator data will be collected on pre-production activities (drilling, fracturing, completion) to estimate emissions from mobile sources (PM generated by truck traffic) and from temporary engines used on-site for drilling, auxiliary power, and fracturing operations (PM and NOx).
