California regulations require that all underground Gasoline Dispenser Facilities (GDF) be equipped with Phase II vapor recovery systems that have been certified as compatible for fueling vehicles (think hoses) equipped with Onboard Refueling Vapor Recovery (ORVR) systems. So how do you know your GDF needs upgrades? Just give your designated operator or gasoline tank contractor a call and hopefully he/she will have an answer. The deadline for compliance is March 1, 2006.
