Last week, the US EPA extended the rulemaking period on RFS 2 until September 25, 2009. This extends the period by 60 days. While this rulemaking is highly complicated and contentious, it is unclear that extending the comment period will improve this situation. In addition, the effective date of the regulations continues to be delayed. This could undermine Congress’ intentions in passing the Energy Independence and Security Act that established RFS 2. Let’s hope EPA is able to move quickly and efficiently in finalizing and implementing the regulations.
