Can a gallon of ethanol generate more than 1.0 RIN in RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The number of RINs that can be generated for each gallon of renewable fuel are determined by the Equivalence Values. See 80.1415 and 80.1426(f)(2)-(6). Equivalence Values are based on energy content in the renewable fuel in comparison to…

If I produce biodiesel using waste vegetable oil, can I generate more RINs per gallon than if I use virgin soy oil? Would the use of solar panels as a heat source for our process help with our RIN number per gallon?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The number of RINs that can be generated for each gallon of renewable fuel is determined by the Equivalence Values. See regulations at 80.1415(b) and 8.1426(f)(2)(i), for example. Equivalence Values are based on energy content in the renewable…

What is the operational tolerance for denaturant in ethanol to meet the definition of Renewable Fuel? The RFS2 definition calls for a maximum of 2% denaturant. What if the lab results come back higher or lower than 2%? For example, what if the lab results
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The definition of renewable fuel in 80.1401 specifies that the maximum amount of denaturant in ethanol that can be treated as renewable fuel is 2 volume percent. If lab results indicate that the concentration of denaturant is higher…

Does the RRP rule apply to contractors working on homes damaged by a hurricane or other natural disaster?
Damage from a major storm or other natural disaster could result in the need for emergency renovations. Certain requirements of the RRP Rule do not apply to emergency renovations, which are renovation activities that were not planned but result from a sudden, unexpected event that, if not immediately attended to…

If a producer is able to change its D code, can it make retroactive changes in the D code of the RINs it has issued previously during the year or earlier if the production during the previous period would meet the newly classified D code criteria?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Once a RIN is generated and transferred to another party, it cannot be changed. Thus, retroactive changes to D codes in RINs are not allowed.

Does ethanol derived from cellulosic feedstock or sugar have the same Equivalence Value as ethanol derived form corn starch, i.e. 1.0?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Yes. Equivalence Values are based on energy content in the fuel, adjusted for renewable content in comparison to denatured ethanol. See 80.1415(c). Ethanol from starch, sugar, and cellulose is all chemically identical, and is all 100% renewable (none…

What Drives Seasonal CO Emission Trends?
See More Frequent Questions about MOVES and Related Models . Once a vehicle’s engine/catalyst reaches operating temperature, the ambient temperature has little effect on the emissions performance of the vehicle. These “running” emission rates in MOVES have no temperature adjustment. However, during summer months at warm temperatures, MOVES assumes extensive…
