That volume is the highest ever recorded for the month of June following the end of the EPA's summertime ban on E15.

With a volume of 6.29 million gallons, the total volume of E15 sold in the first half of 2019 amounted to 36.6 million gallons.  

The Commerce Department also revised its E15 volume for May to 6.94 million gallons - a new record - from 6.36 million gallons previously.

The department may also revise its numbers for June as there were fewer stations reporting their E15 volumes in June compared to May.

On an annualized basis, E15 sales in Minnesota would hit 73 million gallons this year, well above the 59.4 million gallons achieved in 2018. 

As for other blends, E85 sales in June was 1.34 million gallons, 3.8% higher than the 1.29 million gallons recorded in May. On a six-month cumulative basis, 7.1 million gallons of E85 have been sold in Minnesota this year.
