Frequent Questions

What help does EPA provide regulated parties in identifying and addressing potential Renewable Identification Numbers (RINs) problems?

The EPA’s Moderated Transaction System (EMTS) provides several tools that can help RIN buyers avoid buying, selling and using RINs from questionable sources.

If a RIN buyer has concerns about the validity of RINs it has purchased, the EPA's system allows it to “lock†those RINs and not have them counted towards meeting any RFS requirements.

If a RIN buyer has concerns about specific producers of RINs, the EPA’s system also allows it to block RINs from those producers from being transferred to its account.
