Item 8.01 Other Events

Dynamic Fuels Operations Update

On December 10, 2012, Dynamic Fuels completed turnaround maintenance and commissioning of two new feedstock pre-treatment units at its Geismar facility.  Given the current regulatory and market uncertainty, Dynamic Fuels is monitoring the environment to determine when to commence production.

The economics of the U.S. biomass based diesel industry are currently challenged by significantly lower RIN (renewable identification number) prices. D4 RIN prices averaged $1.39 for the first six months of 2012. As of December 10, 2012, the D4 RIN price was $0.56.   RIN prices at these levels have not been seen since the implementation of the RFS2 program by EPA in July of 2010. 

We remain cautiously optimistic for favorable resolution of the blender’s tax credit in the coming weeks.  The blender’s tax credit is included in the Tax Extenders Bill and could provide a $1 per renewable diesel gallon credit retroactive for 2012 and for 2013. If implemented, Dynamic Fuels would receive approximately $23 million for 2012 production.

The regulatory framework underpinning biomass based diesel production remains intact.  The biomass based diesel mandate for 2013 is 1.28 billion gallons, or 28% above the 2012 mandate.  We expect markets to adjust positively in 2013 due to the higher mandate.


Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
