Despite indications EPA may lower its 2014 requirement for ethanol use under the Renewable Fuel Standard (RFS) – acknowledging the existence of the refining “blend wall” – volumetric levels the agency reportedly is discussing don’t go far enough, and larger concern over the dysfunctional, irreparably damaged RFS would remain.

API Downstream Group Director Bob Greco talked about what EPA might do with next year’s requirements, which could be unveiled soon, during a conference call with reporters.

In a recent video op-ed in USA Today, forum editor David Mastio explains why we use ethanol in gasoline. Don’t worry, it’s not a technical presentation. There’s no scientific or technical rationale given for adding ethanol to gasoline. Ethanol isn’t added to improve engine performance, it doesn’t improve fuel efficiency and, according to Mastio, it increases some kinds of pollution while decreasing others.

Let’s continue discussion of the Renewable Fuel Standard (RFS), it’s detachment from market reality and its impacts on consumers – impacts that go well beyond the oil industry. Yesterday, we looked at the views of the National Chicken Council; today the view from the water, courtesy of the National Marine Manufacturers Association (NMMA).

We expect attacks from ethanol boosters over E15 gasoline, fuel that contains 15 percent ethanol, because their stated mission is to promote more ethanol use.  But, unfortunately for them, the science is clear; E15 has been shown to cause damage in some engines and fuel systems.

Pointing this out, citing tests by the Coordinating Research Council (CRC), an organization that’s the gold standard in terms of automotive research, has drawn some fantastic claims, most recently that the E10 (10 percent ethanol) “blend wall” – the point at which there isn’t enough E10 being sold to accommodate all of the ethanol mandated by federal law – doesn’t actually exist, more on that below.

Last week’s call by AAA for a halt in the sale of gasoline containing 15 percent ethanol – because E15 could damage vehicle engines and void car manufacturers’ warranties – triggered the kind of response you’d expect from the Renewable Fuels Association, ethanol’s biggest supporter.

Here's a classic case of putting the cart before the horse, or in this case approving a new fuel before it's adequately tested.

Why is the Environmental Protection Agency (EPA) in such a hurry to grant a waiver allowing E15 to be sold in the marketplace?
