The proposed rule involves amendments to Chapter 62-252, F.A.C., to revise requirements for gasoline vapor control from gasoline dispensing facilities, and tanker trucks and trailers. The proposed rule would eliminate Stage II vapor recovery requirements for new and upgraded gasoline dispensing facilities in Miami-Dade, Broward and Palm Beach counties and phase out Stage II vapor recovery requirements for existing facilities in those counties. The proposed rule would also apply Stage I vapor recovery requirements statewide to new and upgraded gasoline dispensing facilities, and phase in Stage I vapor control requirements statewide for gasoline dispensing facilities. This rulemaking is being conducted in conjunction with proposed amendments to Chapters 62-210 and 62-296, F.A.C., on the subject of gasoline vapor control.
