Policy. The Board of Directors of the Tulalip Tribes recognizes the need for a special regulation to reduce ozone concentrations as required by the Federal Clean Air Act as amended. Accordingly, the Board has adopted this article to provide for control of photochemically reactive volatile organic compounds (VOC), which are precursors to ozone, to meet the National Ambient Air Quality Standard for ozone.

Special Definitions. When used in this article of the Tulalip Department of Environment:
(a) “Bottom loading”
means the filling of a tank through a line entering the bottom of the tank.
(b) “Bulk gasoline plant”
means a gasoline storage and transfer facility that receives more than 90 percent of its annual gasoline throughput by transport tank, and reloads gasoline into transport tanks.
(c) “Gasoline”
means a volatile organic compound having a true vapor pressure greater than 10.5 kilopascals (kPa) (1.5 pounds per square inch absolute – psia) at 20 degrees Celsius temperature, that is a liquid at standard conditions of 102.9 kPa (14.7 psi) and 20 degrees Celsius, and is used as a fuel for internal combustion engines.
(d) “Gasoline loading terminal”
means a gasoline transfer facility that receives more than 10 percent of its annual gasoline throughput solely or in combination by pipeline, ship or barge, and loads gasoline into transport tanks.
(e) “Petroleum refinery”
means a facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, asphalt, or other products by distilling crude oils or redistilling, cracking, extracting or reforming unfinished petroleum derivatives.
(f) “Submerged fill line”(i) (ii)
means any discharge pipe or nozzle that meets either of the following conditions:
Where the tank is filled from the top, the end of the discharge pipe or nozzle must be totally submerged when the liquid level is six inches from the bottom of the tank.
Where the tank is filled from the side, the discharge pipe or nozzle must be totally submerged when the liquid level is 18 inches from the bottom of the tank.
(g) “Transport tank”
means a container with a capacity greater than 1,000 liters (264 gallons) used for transporting gasoline, including, but not limited to, tank truck, tank trailer, railroad car, and metallic or nonmetallic tank or cell conveyed on a flatbed truck, trailer, or railroad car.
(h) “True vapor pressure”
means the equilibrium partial pressure of an organic liquid (determined with methods described in American Petroleum Institute Bulletin 2517, “Evaporation Loss from Floating Roof Tanks,” February 1989).
(i) “Turnaround”
means the shutting down and starting up of process units for periodic maintenance and repair of equipment, or other planned purpose.
(j) “Vapor recovery system”
means a process that prevents emission to the atmosphere of volatile organic compounds released by the operation of any transfer, storage, or process equipment.
