§ 42-22. Use, handling, storage and sale of flammable liquids.

A. 

No person, firm or corporation shall maintain or conduct a plant for the storage of flammable liquids without having obtained a permit from the Plumbing Inspector. No such permit shall be issued unless the plant and storage facilities conform with the provisions of this section. For the purpose of this section, flammable liquids are divided into two classes, as follows:

(1) 

Class I. Liquids with flash point below 70° F. (21° C.) closed-cup tester, such as ether, carbon bisulphate, gasoline, naphtha, benzol, collodion, liquefied petroleum gas, acetone, alcohol, amyl acetate, toluel, ethyl acetate, methyl acetate.

(2) 

Class II. Liquids with flash point above that of Class I and below 170° F. (86° C.) closed-cup tester, such as kerosene, amyl alcohol, turpentine and fuel oil.

B. 

All tests shall be made in accordance with the methods adopted by the American Society for Testing Materials. In case of tanks for the storage of Class I and II liquids at marketing stations, wholesale storage, port terminals and other properties where flammable liquids are stored in quantities, the distance from the line of the adjoining property which may be built upon shall in no case be less than hereinafter set forth in Table I nor less than double those distances in the case of tanks for the storage of crude petroleum. In particular installations those distances may be increased at the discretion of the Plumbing Inspector.

C. 

Table I. Outside aboveground tanks for Class I and II liquids other than crude petroleum shall not be placed or built nearer to the adjoining property lines than the distances hereinafter respectively set forth in the following table:

Capacity of Tank (gallons)	Minimum of Distances to Line of Adjoining Property (feet)
0 to 12,000	10
12,001 to 30,000	15
30,001 to 250,000	20

D. 

At marketing stations and elsewhere, truck-loading racks shall be separated from tanks, warehouses and other plant buildings by distances at least equivalent to those specified in Table I.

E. 

Table II. Outside aboveground tanks for Class I and II liquids other than crude petroleum shall not be placed or built nearer to one another than the minimum distance hereinafter respectively set forth in the following table:

Capacity of Tank (gallons)	Minimum Distance Between Tanks
	Class II (feet)	Class I (feet)
300 or less	3	3
301 to 18,000	5	5
18,001 to 24,000	5	10
24,001 to 75,000	10	20
75,001 to 150,000	15	30
150,000 to 250,000	20	40

F. 

All aboveground storage tanks containing flammable liquids as defined herein shall be surrounded by a wall of reinforced concrete not exceeding eight feet in height forming an enclosure capable of holding at least 1.10 times the capacity of the tank or tanks so enclosed therein. The total capacity of tanks enclosed within any such enclosure shall not exceed 250,000 gallons, exclusive of tanks already in use. Where existing conditions make it impossible to comply with the provisions of this section with regard to the enclosure of tanks, two or more tanks upon the approval of the Plumbing Inspector may be surrounded and enclosed by a wall of reinforced concrete forming an enclosure capable of holding at least 1.10 times the capacity of the tanks so enclosed therein. All concrete walls so constructed must be approved by the Building Inspector of the Town of Rye. The material and construction of tanks shall conform to the regulations of the National Board of Fire Underwriters. All tanks of an oil storage system shall be connected with each other by a system of pipes so that the entire contents of each tank can be transferred to any other tank at will. All storage plants, including the filling tank, if any, shall be equipped with a fire-extinguishing system satisfactory to the Plumbing Inspector. The thickness, quality of materials, hydrostatic-pressure test, foundations and all connections, fire-protection and extinguishing systems and all other details of construction and installation of all tanks must be according to plans which have received the approval of the Plumbing Inspector. All construction and installation shall be subject to inspection by the Plumbing Inspector. A plant for the storage of flammable oil shall be continuously under the care and supervision of one or more persons who shall be thoroughly familiar with the dangers incident to the storage of flammable oils and the operation of fire-extinguishing devices.
