§ 90.005  STORAGE OF PETROLEUM.
   A person shall not place, store or hold in any stationary tank, reservoir or other container of more than 65,000 gallons capacity any petroleum product or mixture of products having a vapor pressure of 2 pounds per square inch absolute or greater under actual storage conditions, unless the tank, reservoir or other container is a pressure tank maintaining working pressures sufficient at all times to prevent hydrocarbon vapor or gas loss to the atmosphere, or is designed and equipped with 1 of the following vapor loss control devices, properly installed, in good working order and in operation.
   (A)   A floating roof, consisting of a pontoon type or double deck type roof, resting on the surface of the liquid contents and equipped with a closure seal to close the space between the roof edge and tank wall.  The control equipment provided for in this division shall not be used if the gasoline or petroleum distillate has a vapor pressure of 12 pounds per square inch absolute or greater under actual storage conditions.  All tank gauging and sampling devices shall be gas-tight, except when gauging or sampling is taking place.
   (B)   A vapor recovery system, consisting of a vapor gathering system capable of collecting the hydrocarbon vapors and gases discharged and a vapor disposal system capable of processing the hydrocarbon vapors and gases so as to prevent their emission to the atmosphere and with all tank gauging and sampling devices gas-tight, except when gauging or sampling is taking place.
   (C)   Other equipment of equal efficiency; however, plans for the equipment must be submitted to and approved by the Chief of the Department of Air Pollution Control.
