This past May, the EPA released its 2017 RFS volume standards. The 2017 levels are a 3.8% increase over 2016 but are still well below the original levels for the year as proposed in 2007.
In both the stakeholder commentary period and the period immediately following the volumes' release, we saw the usual cast of characters come forward with their concerns about the mandated levels. That included biofuels proponents who see the EPAs levels as a "cave" over the blend wall, and industry members who are concerned about the market and practical feasibility of ever increasing levels and who carries the obligation to meet mandated levels.
You can read more in depth about the diverse reactions the EPA ruling had in the recent article I wrote for Oil & Energy magazine here: "Proposed RFS Changes Draw Diverse Reactions"
