The in-use production volumes of renewable fuel are expected to exceed the requirements of the RFS program by a substantial margin. As a result, we expect there to be a surplus of RINs for at least the first few years of the program, and this surplus means it is highly unlikely that non-obligated parties could acquire and retain enough RINs to cause a shortage.

In addition, we expect refiners and other obligated parties to take ownership of renewable fuel with assigned RINs directly from producers in a majority of cases. Nevertheless, EPA will monitor program implementation to ensure that RINs that have been generated are making their way to the obligated parties that need them.
