Sec. 60.101  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A.
    (a) Petroleum refinery means any facility engaged in producing 
gasoline, kerosene, distillate fuel oils, residual fuel oils, 
lubricants, or other products through distillation of petroleum or 
through redistillation, cracking or reforming of unfinished petroleum 
derivatives.
    (b) Petroleum means the crude oil removed from the earth and the 
oils derived from tar sands, shale, and coal.
    (c) Process gas means any gas generated by a petroleum refinery 
process unit, except fuel gas and process upset gas as defined in this 
section.
    (d) Fuel gas means any gas which is generated at a petroleum 
refinery and which is combusted. Fuel gas also includes natural gas when 
the natural gas is combined and combusted in any proportion with a gas 
generated at a refinery. Fuel gas does not include gases generated by 
catalytic cracking unit catalyst regenerators and fluid coking burners. 
Fuel gas does not include vapors that are collected and combusted to 
comply with the wastewater provisions in Sec. 60.692, 40 CFR 61.343 
through 61.348, or 40 CFR 63.647, or the marine tank vessel loading 
provisions in 40 CFR 63.562 or 40 CFR 63.651.
    (e) Process upset gas means any gas generated by a petroleum 
refinery process unit as a result of start-up, shut-down, upset or 
malfunction.
    (f) Refinery process unit means any segment of the petroleum 
refinery in which a specific processing operation is conducted.
    (g) Fuel gas combustion device means any equipment, such as process 
heaters, boilers and flares used to combust fuel gas, except facilities 
in which gases are combusted to produce sulfur or sulfuric acid.
    (h) Coke burn-off means the coke removed from the surface of the 
fluid catalytic cracking unit catalyst by combustion in the catalyst 
regenerator. The rate of coke burn-off is calculated by the formula 
specified in Sec. 60.106.
    (i) Claus sulfur recovery plant means a process unit which recovers 
sulfur from hydrogen sulfide by a vapor-phase catalytic reaction of 
sulfur dioxide and hydrogen sulfide.
    (j) Oxidation control system means an emission control system which 
reduces emissions from sulfur recovery plants by converting these 
emissions to sulfur dioxide.
    (k) Reduction control system means an emission control system which 
reduces emissions from sulfur recovery plants by converting these 
emissions to hydrogen sulfide.
    (l) Reduced sulfur compounds means hydrogen sulfide 
(H2S), carbonyl sulfide (COS) and carbon disulfide 
(CS2).
    (m) Fluid catalytic cracking unit means a refinery process unit in 
which petroleum derivatives are continuously charged; hydrocarbon 
molecules in the presence of a catalyst suspended in a fluidized bed are 
fractured into smaller molecules, or react with a contact material 
suspended in a fluidized bed to improve feedstock quality for additional 
processing; and the catalyst or contact material is continuously 
regenerated by burning off coke and other deposits. The unit includes 
the riser, reactor, regenerator, air blowers, spent catalyst or contact 
material stripper, catalyst or contact material

recovery equipment, and regenerator equipment for controlling air 
pollutant emissions and for heat recovery.
    (n) Fluid catalytic cracking unit catalyst regenerator means one or 
more regenerators (multiple regenerators) which comprise that portion of 
the fluid catalytic cracking unit in which coke burn-off and catalyst or 
contact material regeneration occurs, and includes the regenerator 
combustion air blower(s).
    (o) Fresh feed means any petroleum derivative feedstock stream 
charged directly into the riser or reactor of a fluid catalytic cracking 
unit except for petroleum derivatives recycled within the fluid 
catalytic cracking unit, fractionator, or gas recovery unit.
    (p) Contact material means any substance formulated to remove 
metals, sulfur, nitrogen, or any other contaminant from petroleum 
derivatives.
    (q) Valid day means a 24-hour period in which at least 18 valid 
hours of data are obtained. A ``valid hour'' is one in which at least 2 
valid data points are obtained.
