Date Description Document Docket
10/16/2008 Control of Hazardous Air Pollutants From Mobile Sources: Early Credit Technology Requirement Revision; Final Rule

This action adds another specific benzene control technology, benzene alkylation, to the four operational or technological changes that the 2007 rule currently allows. This action also allows refiners to request EPA approval of other benzene-reducing operational changes or technologies for the purpose of generating early credits

5/9/2008 Control of Hazardous Air Pollutants From Mobile Sources: Early Credit Technology Requirement Revision; Withdrawal of Direct Final Rule

On March 12, 2008, EPA published a direct final rule (DFRM) and a parallel proposal 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. We stated in that direct final rule that if we received adverse comments by April 11, 2008, the direct final rule would not take effect and we would publish a timely withdrawal in the Federal Register. We received adverse comment on the rule and are withdrawing the direct final rule. We will address those comments in any subsequent final action, which will be based on the parallel proposed rule.

Implementation & Support

Summary and Analyses of the Gasoline Benzene Pre-compliance Reports Most refiners that are planning to produce or import gasoline after January 1, 2011 are required to submit annual benzene pre-compliance reports to EPA. Annually in June, EPA provides a summary and analysis of the reports that are received for a given reporting period. The analysis includes some comparisons to the benzene pre-compliance reports received in the prior reporting period. The pre-compliance reports generally show that refiners are planning to comply with the benzene standards on time by installing new benzene removal equipment at many of their refineries, and using the averaging, banking and trading provisions in the regulations to comply at the rest.
