R307.  Environmental Quality, Air Quality.
R307-501.  Oil and Gas Industry:  General Provisions.
R307-501-1.  Purpose.
	R307-501 establishes general requirements for prevention of emissions and use of good air pollution control practices for all oil and natural gas exploration and production operations, well production facilities, natural gas compressor stations, and natural gas processing plants.

R307-501-2.  Definitions.
	(1)  The definitions in 40 CFR 60, Subpart OOOO Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution, which is incorporated by reference in R307-210 apply to R307-501.
	(2)  "Well production facility" means all equipment at a single stationary source directly associated with one or more oil wells or gas wells.  This equipment includes, but is not limited to, equipment used for production, extraction, recovery, lifting, stabilization, storage, separation, treating, dehydration, combustion, compression, pumping, metering, monitoring, and flowline.
	(3)  "Oil well" means an onshore well drilled principally for the production of crude oil.
	(4)  "Oil transmission" means the pipelines used for the long distance transport of crude oil, condensate, or intermediate hydrocarbon liquids (excluding processing).  Specific equipment used in transmission includes, but is not limited to, the land, mains, valves, meters, boosters, regulators, storage vessels, dehydrators, pumps and compressors, and their driving units and appurtenances.  The transportation of oil or natural gas to end users is not included in the definition of "transmission".

R307-501-3.  Applicability.
	(1)  R307-501 applies to all oil and natural gas exploration, production, and transmission operations; well production facilities; natural gas compressor stations; and natural gas processing plants in Utah.
	(2)  R307-501 does not apply to oil refineries.

R307-501-4.  General Provisions.
	(1)  General requirements for prevention of emissions and use of good air pollution control practices.
	(a)  All crude oil, condensate, and intermediate hydrocarbon liquids collection, storage, processing and handling operations, regardless of size, shall be designed, operated and maintained so as to minimize emission of volatile organic compounds to the atmosphere to the extent reasonably practicable.
	(b)  At all times, including periods of start-up, shutdown, and malfunction, the installation and air pollution control equipment shall be maintained and operated in a manner consistent with good air pollution control practices for minimizing emissions.
	(c)  Determination of whether or not acceptable operating and maintenance procedures are being used will be based on information available to the director, which may include, but is not limited to, monitoring results, infrared camera images, opacity observations, review of operating and maintenance procedures, and inspection of the source.
	(2)  General requirements for air pollution control equipment.
	(a)  All air pollution control equipment shall be operated and maintained pursuant to the manufacturing specifications or equivalent to the extent practicable and consistent with technological limitations and good engineering and maintenance practices.
	(b)  The owner or operator shall keep manufacturer specifications or equivalent on file.
	(c)  In addition, all such air pollution control equipment shall be adequately designed and sized to achieve the control efficiency rates established in rules or in approval orders issued under R307-401 and to handle reasonably foreseeable fluctuations in emissions of VOCs during normal operations.  Fluctuations in emissions that occur when the separator dumps into the tank are reasonably foreseeable.
