Current through June 14, 2024
A. Unless otherwise expressly defined in this
				  section, the terms used in this regulation shall be defined by reference to
				  (General Definitions), Part 0 of this Subchapter. As used in this regulation,
				  the following terms shall, where the context permits, be construed as follows:
1. "Combustion device" means emission control
				  equipment used for combustion or destruction of organic vapors and includes,
				  but is not limited to, thermal incinerators, catalytic incinerators, flares,
				  boilers, and process heaters.
2.
				  "Emission control equipment" means any equipment, machinery, apparatus, or
				  device used to recover or reduce emissions of volatile organic
				  compounds.
3. "Gasoline" means any
				  petroleum distillate having a Reid vapor pressure of more than 4 psia as
				  determined by ASTM Method D323. This term includes but is not limited to
				  mixtures of alcohols and gasoline.
4. "Leak free" means the dripping of a liquid
				  containing volatile organic compounds at a rate of four drops per minute or
				  less; or an emission of gaseous volatile organic compounds which causes an
				  appropriate analyzer sampling one centimeter or less from a source to register
				  less than 10,000 ppm as methane.
5.
				  "Loading event" means an incident or occurrence beginning with the connecting
				  of marine terminal storage tanks to a marine tank vessel by means of pipes or
				  hoses followed by the transferring of organic liquid cargo and ending with the
				  disconnecting of the pipes or hoses; or any means of admitting any other liquid
				  into a marine vessel's cargo tanks. Loading events shall include only such
				  incidents which occur when a marine tank vessel is moored to a dock or other
				  permanent stationary structure.
6.
				  "Marine tank vessel" means any marine vessel which is specially constructed or
				  converted to carry liquid bulk cargo in tanks.
7. "Marine terminal" means any facility,
				  equipment, or structure constructed to load or unload organic liquid bulk cargo
				  into or out of marine tank vessels.
8. "Marine vessel" means any tugboat, tanker,
				  freighter, passenger ship, barge or other boat, ship or water craft except
				  those used primarily for recreation.
9. "Organic liquid" means, for the purposes
				  of this regulation, gasoline, gasoline blending stocks, aviation gas and
				  aviation fuel which contains gasoline, such as JP-4 type.
10. "Recovery device" means emission control
				  equipment used to remove organic vapors and recover liquids or chemicals and
				  includes, but is not limited to, absorbers, carbon absorbers, and
				  condensers.
11. "Segregated
				  ballasting operations" means the loading of ballast water into tanks on a
				  marine vessel if those tanks are used only for ballasting and never hold
				  organic liquid.
12. "Vapor tight
				  marine vessel" means a marine vessel which has been demonstrated within the
				  previous 12 months to have no leaks. A marine vessel loaded at negative
				  pressure is assumed to be vapor tight for the purposes of this regulation.
				  Discharges from pressure/vacuum relief valves on cargo tank vent lines are not
				  considered leaks for the purposes of this definition.
