This week, Ethanol activists in Chicago used the 20th anniversary of the BP Oil Spill in the Gulf to push for approval of a pending mandate that would require self-serve stations with over 850,000 gallons in annual sales volumes to carry E15, given they had the proper infrastructure for the blend. They argued that companies will "keep on spilling" and that made it imperative that the push continue towards higher blended, "cleaner" ethanol.
On the flip side, on April 21st, major petroleum groups API and AFPM requested the EPA ban the sale of E15 as a flex fuel. E10 Ethanol has a 1 psi volatility waiver that allows it to be RVP compliant in summer months. E15 is not compliant, however. The argument then is that stations, etc, are using E15 as a flex fuel in the summer months to avoid having to comply with RVP regulations.
The EPA is expected to formally announce the RFS volume requirements any day now, but even prior to the announcement there is action on the RFS in the legislature. House Bill HR 701 would cap ethanol at 10% blends, and rescind the EPA's approval of E15 blends.
Another part of the bill states that target numbers for cellulosic ethanol goals need to be production based, which obviously makes sense, since one of the major issues with the RFS has been the cellulosic mandate in the face of a complete lack of cellulosic production.
I wrote an article for this months Oil & Energy Magazine detailing the growing dissension between RFS involved groups, impacted industries, the EPA and the Government - you can read that article here:
