This topic deserves (and will get) some deeper analysis, but here's a quick summary of the biofuels-related bills that are pending in the Arizona legislature this session:
1. HB 2766, the "Omnibus Energy Act of 2008," which (among many other things) calls for a B2 biodiesel mandate after regional production in AZ, NV, CA, UT, and NM reaches 5 million gallons per year of biodiesel, then steps the mandate up to B5 after 15 million gallons regional production is reached.
2. HB 2620, the "Biofuels Conversion Program," which "establishes the Arizona Biofuels Conversion Program in the Department of Commerce (DOC) to encourage the use of biofuel."
3. HB 2621, "Biofuel Standards," which "establishes standards for biofuel relating to labeling, product transfer documents, registration and reporting requirements."
4. HB 2363, called "Weights and Measures; Biofuels Rules," which we have discussed before, and which may have been subsumed by HB 2621 (they cover similar ground).
Big hat tip to Jim Lombard of Roadrunner Biodiesel and the AZ Biodiesel Board for his work in tracking these bills.
