The type and amount of such foam protection system shall be subject to the approval of the Fire Chief; provided, however, that when such tank or group of tanks are horizontal cylindrical tanks, or spheroidal tanks, or have pontoon type floating roofs or vapor recovery systems installed, maintained and operated thereon so that the vapors within such tanks will exceed the explosive limits for petroleum vapor-air mixtures, foam shall not be required except in the quantity necessary for extinguishing ground fires for such tanks as provided in this Article.
Whenever, in the opinion of the Fire Chief, an unusually hazardous condition exists by reason of the failure to keep and maintain any tank, group of tanks, or other apparatus or facility used to hold, handle or process oil, in a safe and proper condition as required by the provisions of this Article, or by reason of the failure to keep the premises clean on which the same is situated, as provided in this Article, or by reason of the failure to employ practices in the operation of the same in conformity with the requirements of this Article, the Fire Chief may require foam to be provided for such tank, group of tanks, apparatus or facility, in the quantity required by the provisions of this Article for extinguishing ground fires for a tank with an oil-surface area equivalent to the ground surface area occupied by such tank, group of tanks, apparatus or facility. The provisions of this Section may be applied regardless of whether the oil in such tank, group of tanks, apparatus or facility is crude oil or refined oil.
Whenever foam protection is required for tank fire extinguishment for any single tank there shall be provided for such purpose the following quantities of foam for each square foot of oil-surface area in such tank, according to the method of applying such foam, to wit:
(1) 
Non-splash application: thirty gallons
(2) 
Foam nozzle stream application: eighty gallons
(3) 
Other types of application: fifty gallons
Whenever foam protection is required for tank fire extinguishment for any group of tanks consisting of not more than two tanks, there shall be provided for such purpose the quantity of foam required by the provisions of this Article for a tank having the same oil-surface area as that of the largest tank in such group.
Whenever foam protection is required for tank fire extinguishment for any group of tanks consisting of more than two tanks, there shall be provided for such purpose the quantity of foam required by the provisions of this Article for a tank having the same oil surface as that of the largest tank in such group, plus twenty percent of the quantity required by said Section for a tank having the same oil-surface area as that of the second largest tank in such group, plus ten percent of the quantity required by said Section for a tank having the same oil-surface area as the total oil-surface area of all of the remaining tanks in said group; provided, however, that if the tanks in any such group are separately diked, or otherwise surrounded to the satisfaction of the Fire Chief, or are separated, shell to shell, a distance not less than the diameter of the largest tank, the quantity of foam required for tank fire extinguishment shall be only such amount as is required by this Article for a tank having the same oil-surface area as that of the largest tank in such group.
Whenever foam protection for the purpose of ground fire extinguishment is required, there shall be provided for such purpose (in addition to the quantity of foam required by the provisions of this Article for tank fire extinguishment) the following quantity of foam, according to the total oil-surface area for which such protection is required, to wit:
TOTAL OIL SURFACE AREA TO BE PROTECTED
QUANTITY OF FOAM
Less than 2,000 sq. ft.
5,500 gals.
2,000 to 3,000 sq. ft.
10,000 gals.
over 3,000 sq ft.
20,000 gals.
In determining whether an adequate supply of foam solutions is being maintained to create the foam required (whether for tank fires or for ground fires) it shall be considered that eight gallons of foam is produced by the combining of one pound of Underwriters Approved dry foam chemicals with one gallon of fresh water at sixty degrees Fahrenheit, or the combining of one-half gallon each of A solution and B solution; provided, however, that all such solutions shall be so maintained that the production of not less than six gallons of foam results from the combining of one-half gallon each of A and B solutions at a temperature of sixty degrees Fahrenheit.
(a) 
Each person required to provide foam protection shall provide means of producing and applying such foam at a rate based on the method of applying foam to the oil-surface. A non-splash applicator shall be any device, portable or fixed to the tank shell, by which foam can be applied under severe fire conditions onto the oil-surface regardless of depth, at a velocity not in excess of that acquired by a free downward fall of foam through a vertical distance of four feet. When such non-splash application is employed, a rate of three-eighth gallons per minute of foam for each square foot of normal oil-surface of the largest tank protected by the system will be acceptable.
(b) 
When other than non-splash applicators, excepting foam nozzle streams are employed, a rate of three-quarters gallon per minute per square foot of the largest tank protected shall be available.
(c) 
When foam nozzle streams are employed, the application rate shall be one gallon per minute per square foot of normal oil surface of the largest tank protected; provided, however, that hose streams shall not be the sole means available for applying foam onto a tank having more than one thousand square feet of normal oil-surface.
(d) 
No application rate, whether for tank fires or ground fires, shall be less than three hundred gallons per minute of foam regardless of lesser area requirements provided herein.
A separate license and a separate permit must be procured under this Article for each individual oil well or gas well. Notwithstanding the provisions of this Article, the permit fee for each such well shall be $1,000.00 which shall be paid at or before the time of the issuance of such permit.
