On the registration forms it seems you are forced to check only one primary activity (refiner, oxygenate blender, importer, or independent lab). Do you submit two forms if you are both a refiner and importer?
No. The final forms have been changed to register each company once for all applicable activities. As before, each facility will be registered separately for each activity that is undertaken at the facility. Import facilities need not be registered individually (see question 10 in this section).(7/1/94)
