(d) "Fixed roof stationary vessel" means a stationary vessel with a roof connected in a rigid fashion to the side walls of the vessel, a spherically-shaped vessel, or a pressure vessel designed to maintain a specific working pressure. (e) "Flexible coating" means any coating that is required to comply with engineering specifications for impact resistance, mandrel bend, or elongation as defined by the original equipment manufacturer. (f) "Flexographic printing" means the application of words, designs, or pictures to a substrate by means of a roll printing technique in which the pattern to be applied is raised above the printing roll and the image carrier is made of rubber or other elastomeric materials. (g) "Fog coat" means a coating that is applied to a plastic part for the purpose of color matching without masking a molded-in texture. A fog coat shall not be applied at a thickness of more than 0.5 mils of coating solids. (h) "Fossil fuel-fired steam generator" means a furnace or boiler used in the process of burning fossil fuel for the primary purpose of producing steam by heat transfer. (i) "Fuel-burning equipment" means a device, contrivance, or equipment used principally, but not exclusively, for the burning of fuel, and all appurtenances thereto, including ducts, breechings, control equipment, fuel-feeding equipment, ash removal equipment, combustion controls, and stacks and chimneys, which equipment is used for indirect heating in which the material being heated is not contacted by, and does not add substance to, the products of combustion. This equipment typically includes that used for all of the following: (i) Heating water to boiling. (ii) Raising steam or superheating steam. (iii) Heating air as in a warm-air furnace. (iv) Furnishing process heat that is conducted through vessel walls. (v) Furnishing process heat indirectly through its transfer by fluids. (j) "Fuel gas system" means any system in which gas generated by a petroleum refinery process unit is combusted, including any gaseous mixture of natural gas with such gas, and is not commercially sold. (k) "Fugitive dust" means particulate matter that is generated from indoor processes, activities, or operations and that is emitted into the outer air through building openings and general exhaust ventilation, except stacks. The term also means particulate matter that is emitted into the outer air from outdoor processes, activities, or operations due to the forces of the wind or human activity. (l) "Fugitive emissions" means those emissions which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.
