That takes you to an EPA link of the rules and regs for getting a fuel or additive registered. I'd really, really appreciate someone pointing me to the place where it says any fuel or additive is exempt from registration.

There are several cases that exempt manufacturers from Tier 1 and 2 testing requirements, but every single such exemption also notes the requirement for applying for and getting an EPA registration.
