(1) Excludes emissions from natural gas pilots and purges.
(2) Pilot gas (NG) rates are 4,800 scfd each for North and South Flares.
(3) Flare header pressure greater than water seal setpoint, corroborating flow.
(4) Raw flow representative of flows between 0.1 - 275 ft/s per 12-11-501.2 and 40CFR60.107a(f)(1)(ii).
(5) Purge gas (nitrogen) rates are based on RO size and hours in the day the purge was on.
