Approval of Discontinuation of Tail Pipe Lead and Fuel Inlet Test for Vehicle Antitampering Program for Oklahoma

The EPA is approving the State Implementation Plan (SIP) revision submitted by the State of Oklahoma for the purpose of discontinuing the State's tail pipe lead and fuel inlet test in its vehicle antitampering program. The SIP revision also includes minor administrative changes related to the Oklahoma antitampering program. The SIP revision was submitted by the State in response to the dramatic diminished availability of leaded fuel which has resulted in a lack of a need for these tests, not only in Oklahoma but also nationwide. The rationale for the approval is set forth in this document; additional information is available at the address indicated in the ADDRESSES section.
