Rule Summary

EPA is taking final action to revise the February 26, 2007 mobile source air toxics rule’s requirements that specify which benzene control technologies a refiner may utilize to qualify to generate early benzene credits. This action will allow another specific benzene control technology, benzene alkylation, in addition to the four operational or technological changes specified in the current rule. This action also includes a general provision that allows a refiner to submit a request to EPA to approve other benzene-reducing operational changes or technologies for the purpose of generating early credits.
