Is SVO biomass as far as renewable energy credits are concerned?

I'm planning an on-grid commercial/residential solar "generation facility" (as the local utility refers to it), with a diesel prime generator that I hope to run on WVO.

While looking into grid-tieing the system, I saw that renewable energy credits are available for biomass, provided it is harvested sustainably.

Doesn't WVO fit that description?

I plan to call the relevant agencies and start inquiring tomorrow, as I have had no luck finding any info online.  Meanwhile, I'm wondering if anyone here has any info as to that.

Also, I can't find anything concrete the EPA has to say about WVO in stationary engines.  What's the deal there?

Thanks in advance!
