If liquefied gasses are in contact with any valve or fitting, the <br /> liquid flow rate shall be utilized for purposes of computation of the <br /> maximum flow rate of release. All flow rates indicated on the label <br /> shall be converted to cubic feet per minute of gas at normal temperature <br /> and pressure. <br /> <br /> (6) Portable tanks and cylinders. <br /> <br /> [i] For portable tanks and cylinders, the maximum flow rate of <br /> release shall be calculated based on assuming the total release from the <br /> cylinder or tank within the time specified in the Table below: <br /> <br /> _ Non-liquefied Liquefied <br /> Container Minutes Minutes <br /> <br /> Cylinders 5 30 <br /> Portable Tanks 40 240 <br /> <br /> [ii] When portable tanks or cylinders are equipped with approved <br /> reduced flow valves, the worst case release will be detennined by the <br /> maximum achievable flow from the valve as determined by the valve <br /> manufacturer or the gas supplier. Reduced flow and excess flow valves <br /> shall be permanently marked to indicate the maximum design flow rate. <br /> Such markings shall indicate the flow rate for air under standard <br /> conditions. <br /> <br /> f. Exterior Storage. <br /> <br /> (1) General. Persons responsible for a facility where there is exterior <br /> storage of any regulated material shall comply with the provisions of this <br /> subsection (f) and of the Uniform Building Code referenced in the <br /> Pleasanton Municipal Code. <br /> <br /> <br />
