Air Pollution Control Program
Vapor Recovery Rules Stakeholder Workgroup
Background | Meeting Summaries | Related Documents | Related Links
The Vapor Recovery Rulemaking is indefinitely on hold.
The Air Pollution Control Program placed the rulemaking on hold for three main reasons:
- There is a great deal of uncertainty surrounding timelines and implementation of the 2008 ozone standard now in effect.
- Guidance about phase out of Stage II vapor recovery based on "widespread use" of onboard refueling vapor recovery in the vehicle fleet is forthcoming.
- Many of the facilities impacted by our state rules are now also covered by a new set of federal regulations for gasoline dispensing facilities (6B and 6C).
- When the impacts of these new and forthcoming federal regulations become clearer, the group could be reconvened.
The department will continue to work to implement workgroup suggestions that fall within the areas of policy or guidance and are not necessarily spelled out in the state's existing vapor recovery rules.
The Vapor Recovery Workgroup had been formed when the Missouri Department of Natural Resources received approval to amend Missouri’s Vapor Recovery Rules 10 CSR 10-2.260 and 10 CSR 10-5.220.
Stage I Vapor Recovery is the capture and control of gasoline vapors that would normally be released into the atmosphere during the storage of gasoline at a terminal or bulk plant or during the loading of a gasoline delivery vessel and the subsequent delivery and unloading of a gasoline delivery vessel into another storage tank, usually at a Gasoline Dispensing Facility, or GDF.
Stage II Vapor Recovery is the capture and control of gasoline vapors that would normally be released into the atmosphere during the refueling of motor vehicles at a GDF. When you refill your automobile gas tank, the fresh gas forces out the vapors left in the tank from the last tankful into the atmosphere. Stage II Vapor Recovery, recognized by the black boots on the gasoline nozzles at St. Louis area stations, captures the vapors from the automobile tank and returns these vapors to the Underground Storage Tank at the GDF. The storage tank holds the vapors until a gasoline delivery vessel using Stage I Vapor Recovery refills the tank. These vapors are then returned, by way of the gasoline delivery vessel, back to the terminal for processing or destruction.
