Illinois

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.

EPA waived the summer max. 7.2 psi RVP gasoline standard for Madison, Monroe, and St. Clair counties temporarily between June 25 and August 4, 2006 because of a disruption in supply due to a severe thunderstorm. See letter dated 6/25/06.

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.
