v. Vapor recovery process
v.a. In all cases where underground tanks are equipped with
any type of vapor recovery system, all connections shall
be safe and designed to prevent release of vapors at
grade level and shall remain connected throughout the
loading and unloading process.

required, the tank vapor system shall be open to the
atmosphere to prevent pressurization of the tank and the
vapor system.
v.c. The vapor recovery connection of the bottom-loading
tank vehicles equipped with a vapor recovery system shall
be used to lead vapor away from the loading area using
terminal vapor recovery system, discharge standpipe, or
by opening the tank fill opening (manholes).
v.d. Where a “dry disconnect vapor recovery adapter” is used,
provisions shall be made to ensure that the vapor recovery
system is fully vented before unloading to prevent collapse
of the tank.
