Current Regulations: Three counties (Madison, Monroe and St. Clair; part of the St. Louis ozone non attainment area) had a summer max. 7.2 psi RVP gasoline standard.See 35 IL Administrative Code 219.585.

In a letter dated 7/10/06, IL Governor Blagojevich asked EPA to allow East St. Louis (Jersey, Madison, Monroe, and St. Clair Counties) to opt-in to the federal RFG program. EPA set the effective dates at May 1, 2007 for terminals and at June 1, 2007 for retail (see direct final rule at 71 FR 77615; 12 /27/06). EPA withdrew the May 1/June 1 effective dates (72 FR 14681; 3/29/07) and set June 1, 2007 at terminal and July 1, 2007 at retail as the RFG effective dates for East St. Louis (72 FR 20237; 4/24/07).

Federal RFG is required in Chicago, summer and winter.
