Revisions to the Requirements on Variability in the Composition of Additives Certified Under the Gasoline Deposit Control Program; Final Rule

On November 5, 2001, we published a direct final rule and concurrent notice of proposed rulemaking to revise the requirements on variability in the composition of additives certified EPA's Gasoline Deposit Control Program. We received adverse comments on two of the amendments contained in the direct final rule and proposed rule. Consequently, we issued a partial withdrawal notice on January 24, 2002, to withdraw the amendments that received adverse comments. This action addresses the public comments received on the withdrawn amendments. We found the adverse comments on the withdrawn amendments unpersuasive. However, we agreed with one commenter's suggestion that additional clarifying language would be useful in one of the subject amendments to prevent any potential for misinterpretation. Consequently, today's action implements the previously withdrawn amendments with the addition of clarifying language. The changes to the regulatory requirements made by this action address additive manufacturer concerns that compliance with the previous requirements would be burdensome and difficult, while maintaining the emissions control benefits of the gasoline deposit control program.
