Monday:
On a side note you or your supplier(s) may want to look into futures trading as a hedge (commodities). With out getting too much into the subject you pretty much lock in your costs etc.
I have not been involved in that business for years. It only looks sophistiated it's really not. With the numbers you are talking about I would consult the dept. of energy for advice. They do work for you and if they don't get that your congress person can explain that to them.
Yeah, I'm trying to structure things so we can "lock in" prices no higher than $4-$5/gal retail w/o any involved getting scrod. After all, I want everyone involved in this to do well. If my suspicions are correct, we are going to need robust working producer consumer biodiesel relationships sooner rather than later.
The State and Town officials looking into these deals will be looking into the hedge sort of stuff as well. 
However, thanks for putting this sort of thing into the public eye on BDN. I had not thought of saying anything about it.
Note to readers. "Hedge" does not mean "guarantee". Hedges can reduce risk. Often a great deal. But they do not =remove= risk.
