Frequent Questions

In areas where an oxy fuels program is in effect, how do these requirements coincide with RFG requirements? In areas where there is an overlap, are any regulatory changes necessary by the state?

In areas that are covered by both a state's winter oxy fuels and the federal RFG programs, the fuel must comply with both program requirements. Therefore, the more stringent 2.7 wt% minimum requirement of the winter oxy fuels programs must be met during the oxy control period. States do not have to make any regulatory changes.(7/1/94)
