3. Except
as provided in (a) 3iv and v below, to prevent spilling and overfilling associated
with product transfer to the underground storage tank system, owners and operators
shall use the following:
i. Spill prevention
equipment that shall prevent release of product to the environment when the transfer
hose is detached from the fill pipe (for example, a spill catchment
basin);
ii. Overfill prevention
equipment, compatible with the delivery method used to fill the tank, that shall:
(1) Automatically shut off flow into the tank when
the tank is no more than 95 percent full;
