Vapor Recovery Equipment Defects (VRED)

This page last reviewed August 27, 2012


The ARB evaluates and tests new or modified vapor recovery systems.  These systems recover the gasoline vapors generated while fueling vehicles in a service station.  During the certification process, vapor recovery systems are evaluated for defects that substantially impair the efficiency of the system.  Those defects identified as 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 necessary.  For further information please see the California Health & Safety Code; Section 41960.2(c)&(d).
