(1) Excludes emissions from natural gas pilots and purges.
(2) Pilot gas (NG) rates are 4,800 scfd each for North and South Flares based on design of pressure regulator and nozzle size at flare tip.
(3) Natural gas purge rate to North Flare is 0.13 mmscfd based on restriction orifice size.
(4) Flare header pressure greater than water seal setpoint, corroborating flow.
(5) Raw flow representative of flows between 0.1 - 275 ft/s per 12-11-501.2
and 40CFR60.107a(f)(1)(ii).
