Control of Hazardous Air Pollutants From Mobile Sources: Early Credit Technology Requirement Revision

EPA is taking direct final action to revise the February 26, 2007 mobile source air toxics rule's requirements that specify the benzene control technologies that qualify a refiner 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 that the 2007 rule currently allows. 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.
