These extra valves are not required in crude oil tanks in oil fields, on tanks at refineries, or on tanks at terminals which are equipped with a swing line or where facilities are provided to transfer the contents of the tank to another tank in case of fire. On tanks installed prior to April 14, 1977, emergency check valves may be external, if the size of the opening is too small to admit the smallest emergency check valve provided:

 

a)         The valve used incorporates a shear section, and

 

b)         The valve is so installed that any undue strain beyond the valve will not cause failure between the valve and the tank.

Class A:          Transports are further defined as those which are used to transport flammable and combustible liquids between terminals and bulk plants to service stations and fueling of aircraft.           

 

Class B:          Transports are further defined as those which are used to transport flammable and combustible liquids from terminals and bulk plants to service stations, farm storage sites, construction sites, and for home heating fuel deliveries.

 

Class C:           Transports are further defined as those vehicles which have tanks added after factory manufacture of the vehicle chassis for the purposes of either transporting liquid fuels or added fuel capacity for the vehicle to which the tank(s) have been added.

 

Class A & Class B transport trucks are regulated by both the Federal and State of Illinois Departments of Transportation by virtue of the fact that their load weight can equal or exceed 1000 pounds.

 

b)         Up to 110 gallons of Class I, II or III liquids may be carried for added fuel capacity provided that:

 

1)         Any such tank is constructed of 18 gauge or heavier steel, or equivalent gauge aluminum.

 

2)         That such tank is securely fastened to either the truck bed or frame in such a manner that it will not separate from the vehicle in the event of a collision.

 

3)         That such tank is permanently connected to the carburetion system of the vehicle by tubing conforming to 49 CFR 571.301 (1983).
