How long will the grandfathering provision be effective? Once a grandfathered producer registers and completes their engineering review, will their baseline volume ever need to meet the 20% GHG reduction requirement?
If a facility meets the requirements for exemption from the 20% GHG reduction requirement pursuant to 40 CFR 80.1403(c ) or (d), then the baseline volume of renewable fuel produced by that facility is exempt from the 20% GHG reduction requirement for the life of the plant, barring major modifications.
