Nearly 191.36 million D4 biomass-based diesel RINs (approximately 128 million gallons) were generated in March, bringing the net total for the first quarter of 2015 to 472.28 million RINs. A total of 472.44 million D4 RINs were generated during the first three months of the year, with a 154,106 RIN generation error correction. Most—349.69 million—have been generated for biodiesel, with 122.74 million generated for renewable diesel. During the first three months of the year, 394.2 million D4 RINs were generated domestically, with 33.29 million generated by importers and 44.95 million generated by foreign producers.

According to the EPA, 7.8 million D3 cellulosic biofuel RINs were generated in March, bringing the net total for the first three months of the year to 19.73 million. Approximately 19.811 million D3 RINs were generated in total, with 76,942 RIN generation error corrections. EPA data indicates 286,237 D3 RINs were generated for ethanol, with 9.28 million generated for renewable compressed natural gas and 10.25 million for renewable liquefied natural gas. All 19.811 million D3 RINs generated during the first three months of 2015 were generated domestically. No D7 renewable diesel RINs have been generated so far in 2015. 

More than 4.83 million D5 advanced biofuel RINs were generated in March, bringing the net total for the first three months of the year to 14.58 million. That number includes 14.89 million total D5 RINs that were generated, with a 9,279 RIN error correction. Nearly 6.05 million D5 RINs were generated for ethanol, with 6.18 million generated for naptha, 215,890 generated for heating oil, 2.14 million generated for nonester renewable diesel, and 189 generated for renewable compressed natural gas. During the first quarter of 2015, all 14.59 million D5 RINs were generated domestically.

Nearly 1.24 billion D6 renewable fuel RINs were generated in March, bringing the net total for the first three months of the year to 3.57 billion. To date, the EPA has reported 429,829 in RIN generation error corrections for D6 renewable fuel. The majority of D6 RINs, 3.47 billion, have been generated for ethanol, with 7.37 million generated for biodiesel, and 94.2 million generated for nonester renewable diesel. During the first three months of the year, 3.47 billion D6 RINs were generated by domestically, with 8.01 million generated by importers and 94.2 million generated by domestic entities.

Of the 4.75 billion RINs generated so far this year, the EPA notes 104.54 million have been retired, with 144.59 million locked and available and 3.83 million unlocked and available.
