When replacing conventional gasoline with RFG at a terminal, is it considered blending if the RFG is mixed with conventional bottoms?

During the transition period prior to December 1, 1994, certified RFG may be put into tanks that contain conventional gasoline bottoms, as long as the tank is essentially filled with certified RFG gasoline on December 1, 1994, and the gasoline is properly sampled and tested and is in compliance with the RFG downstream standards. After December 1, 1994, the mixing of RFG and conventional gasoline is prohibited.
