Availability of EPA decision denying the Ethyl Corporation petitions to reconsider CAP 2000 regulation, heavy-duty gasoline regulation, and OBD/IM regulation.


The Ethyl Corporation has submitted three petitions to the EPA Administrator to reconsider three separate Agency rulemakings. The first petition is regarding the compliance procedures for new motor vehicles known as “CAP 2000”. 64 FR 23,906. The second petition pertains to emission standards and compliance procedures for new heavy-duty gasoline engines. 65 FR 59896. The third petition pertains to the use of on-board diagnostics for vehicle inspection and maintenance programs. 66 FR 18156.

The Petitioner's issues with the heavy-duty rule are identical to those of the CAP 2000 rule, and EPA agreed that its response would cover both regulations. Although the issue for the OBD/IM rule is different, EPA's response is included in accordance with a commitment to do so made in that rulemaking.

This Notice serves to announce the availability of EPA's decision to deny Ethyl's petition to reconsider all three petitions.
