Frequent Questions

Do facilities for RFG and ULSD have to be the same? Will EPA assign new ID numbers for facilities that already have a facility ID under RFG? Will those existing facilities have to register again?

Facilities for RFG and ULSD can be the same, however they do not have to be the same. EPA may issue a new number if the facility definition changes. Entities should still contact EPA to update their registrations, even if you plan to use the same facility and facility definition that was used for RFG.
