The Air Resources Board (ARB or Board) staff invites you to
participate in a public workshop to discuss conceptual changes to
regulations that control the release of gasoline vapors at
dispensing facilities (service stations) equipped with
underground storage tanks.   
At the workshop, staff will provide a status of the ongoing field
study to determine the prevalence and impact of In-Station
Diagnostic (ISD) system over pressure alarms.  Additionally,
staff will discuss concepts under consideration for second
generation ISD requirements and proposed liquid release standards
for nozzles that do not have vapor return paths (enhanced
conventional nozzles or ECO nozzles).  The workshop will be held
in two locations as indicated below; each workshop will cover the
same topics and will consist of a one hour presentation by ARB
staff, followed by a question-and-answer session.  

Date:	       Friday, March 7, 2014
Time:           10:00 a.m. to 12:00 p.m.

Background: 
Vapor recovery systems at service stations have been used in
California since the 1970s.  These systems control the release of
gasoline vapors into the air when gasoline is transferred from a
tanker truck into a service station’s underground storage tanks
and when gasoline is transferred from these tanks into motor
vehicles.  Most service stations are equipped with an ISD system,
which provides continuous monitoring of critical vapor recovery
components and promptly alerts station owners/operators of any
system failures so that corrective actions can be taken.  Vapor
recovery is an important control measure that contributes to
statewide efforts to attain federal and state health based air
quality standards and to reduce public exposure to benzene, a
toxic air contaminant.  State law provides that only ARB
certified systems can be sold or installed in California and
local air districts are responsible for enforcing vapor recovery
requirements.
