(1) Excludes emissions from natural gas pilots and purge gas.
(2) Pilot gas (NG) rate is 3,600 scfd (based on design of pressure regulator and nozzle size at flare tip). Purge gas (NG) rate is 50,000 scfd (based on globe valve and local flowmeter setpoint).
(3) Emissions based on supplemental FG composition to AG flare due to base loading.
(4) Raw flow representative of flows between 0.1 and 275 ft/s per 12-11-501.2 and 40CFR60.107a(f)(1)(ii).
