The Vapor Recovery Rulemakings related to the below workgroup are indefinitely on hold. However, the Air Pollution Control Program is moving forward with a rule amendment to 10 CSR 10-5.220 to remove Stage II requirements and incorporate several recommendations from these workgroup discussions. Additional information on this rulemaking may be found on the department's webpages: Environmental Protection Agency's Widespread Use Rule and Rules in Development.

In 2011, the Air Pollution Control Program placed the rulemakings being discussed by the workgroup on hold for three main reasons:

  • At the time, there was 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 was forthcoming. (Note that the Environmental Protection Agency has now issued a widespread use determination as described in detail at the department's webpage: Environmental Protection Agency's Widespread Use Rule
  • 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). 

Background

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.
