Vapor Recovery Equipment Defects (VRED)
This page last reviewed March 2, 2015
The ARB evaluates and tests
modified vapor recovery systems. These systems
recover the gasoline vapors generated while fueling vehicles in a
During the certification process, vapor recovery systems are evaluated
for defects that
substantially impair the efficiency of the system. Those
substantially impairing the efficiency of the system are included in
the VRED List (List).
When a defect included in the List is found at a gasoline
dispensing facility, the
air district is required to remove the affected component from service
until repairs are
completed or the component is replaced or adjusted as
