The Vapor Recovery Program controls vapor emissions from gasoline marketing operations (gasoline dispensing facilities or service stations, tanker trucks (cargo tanks), bulk plants, and terminals), where gasoline vapor is a precursor to the formation of ozone and contains benzene, a constituent of gasoline vapor that has been identified as a toxic air contaminant.

2023 Early Transition to Winter Blend Gasoline and In-Station Diagnostic System Overpressure Alarm Response Policy
In response to direction from the Governor, the California Air Resources Board (CARB) is temporarily allowing the sale of winter blend gasoline beginning on September 28, 2023.
From a vapor recovery system perspective, the early introduction of winter blend gasoline (higher volatility) may result in an increase of ISD overpressure alarms. CARB has released a new "Informational Bulletin" temporarily extending Advisory 405-D to allow station owners and operators to clear the alarms without vapor recovery equipment testing or service for ISD overpressure alarms occurring between September 28, 2023 and March 31, 2024. Advisory 405-D is available by clicking here.
