Public Notice: California Mobile Source Regulations; Final Approval and Promulgation of Implementation Plans

Publish Date: 03/21/2017


The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the California State Implementation Plan (SIP) consisting of state regulations establishing standards and other requirements relating to the control of emissions from new on-road and new and in-use off-road vehicles and engines. The EPA is approving the SIP revision because the regulations meet the applicable requirements of the Clean Air Act. Approval of the regulations as part of the California SIP makes them federally enforceable.


This rule is effective on May 22, 2017 without further notice, unless the EPA receives adverse comments by April 20, 2017. If we receive such comments, we will publish a timely withdrawal in the Federal Register to notify the public that this direct final rule will not take effect.
