SANTA BARBARA COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 332 - PETROLEUM REFINERY VACUUM PRODUCING SYSTEMS, WASTEWATER SEPARATORS AND PROCESS TURNAROUNDS
For the purpose of this Rule:
2. "Petroleum refinery" means any facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, or other products through distillation of crude oil, or through redistillation, cracking, extraction, or reforming of unfinished petroleum derivatives.
3. "Process turnaround" means the operation of unit shutdown (i.e., reactors, fractionators, etc.).
4. "Vacuum producing systems" means:
b. Steam ejectors with surface condensers, including hot wells; and
c. Mechanical vacuum pumps.
The provisions of Section D. shall not apply to those sources in the Northern Zone of the County installed prior to May 18, 1979.
C. Requirements for Petroleum Refinery Vacuum Producing Systems
2. Compliance with Section C.1. of this Rule shall be accomplished in part by:
b. Controlling uncondensed organic vapors emitted from vacuum producing systems by methods which the Control Officer has determined will not allow any such vapors to be emitted to the atmosphere.
D. Requirements for Petroleum Refinery Wastewater Separators
b. A floating cover which extends to within 0.125 inches of the wall of said compartment or header at all points on the perimeter of the cover except over a cumulative length of no more than 3% of the perimeter; over said 3% of the perimeter, the cover shall extend to within 0.5 inches of the wall; or
c. Controls which the Air Pollution Control Officer has determined will reduce organic gas emissions from said compartment or header to or below the mass emission rate which would occur if controls described in D.1.a. or D.1.b. were applied.
E. Requirements for Petroleum Refinery Process Turnaround
2. Compliance with Section E.1. of this Rule shall be accomplished by venting all uncondensed organic gases to a fuel gas system or to a flare, or by other methods which the Control Officer has determined will prevent said gases from being emitted to the atmosphere.
3. Upon receipt and validation of documentation of the infeasibility of using existing control facilities to control the purge gas stream from a process vessel, the Control Officer may exempt that process vessel from those requirements of Section E.2. which would otherwise require the control of such purge gases. The necessity to install valves or piping or to purge the process vessel at a lower rate than would otherwise be used shall not constitute grounds for exemption.
