Advisories:

• Special Advisory:  405 b) Response to Winter Season ISD Pressure Alarms
• Special Advisory:  405 a) In Station Diagnostics Alarm Response

Enhanced Vapor Recovery regulations require gasoline dispensing facilities (GDFs) to install an In-Station Diagnostics (ISD) system to monitor vapor recovery system performance.  The attached Air Resources Board Special Advisory and Training Announcement detail changes in how operators of GDF facilities should respond to ISD alarms.  For more information, please contact Stephen Ertle, 530-332-9400.   (Nov, 2010)
