California Waivers and Authorizations

New

July 30 , 2014

  • EPA issues Notice of Decision (PDF) (10 pp, 258K, published August 7, 2014) on California’s Request for Waiver of Preemption of Heavy-Duty Tractor-Trailer Greenhouse Gas Regulations

This page lists Federal Register notices that EPA has issued in response to California waiver and authorization requests. There is no guarantee that this is a complete list, but it should contain nearly everything generated by OTAQ. For more information, please contact David Dickinson (dickinson.david@epa.gov, 202-343-9256). For additional information on California’s greenhouse gas waiver, please visit www.epa.gov/otaq/climate/ca-waiver.htm.

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

Waiver Process

The Clean Air Act allows California to seek a waiver of the preemption which prohibits states from enacting emission standards for new motor vehicles. EPA must grant a waiver, however, before California’s rules may be enforced. When California files a waiver request, EPA publishes a notice for public hearing and written comment in the Federal Register. The written comment period remains open for a period of time after the public hearing. Once the comment period expires, EPA reviews the comments and the Administrator determines whether the requirements for obtaining a waiver have been met.

According to the Clean Air Act Section 209 – State Standards, EPA shall grant a waiver unless the Administrator finds that California:

  • was arbitrary and capricious in its finding that its standards are, in the aggregate, at least as protective of public health and welfare as applicable federal standards;
  • does not need such standards to meet compelling and extraordinary conditions; or
  • such standards and accompanying enforcement procedures are not consistent with Section 202(a) of the Clean Air Act.

Authorization Process

The Clean Air Act allows California to seek authorization to enforce its own standards for new nonroad engines and vehicles, despite the preemption which prohibits states from enacting emission standards for new nonroad engines and vehicles. When California files an authorization request, EPA publishes a notice for public hearing and written comment in the Federal Register. The written comment period remains open for a period of time after the public hearing. Once the comment period expires, EPA reviews the comments and the Administrator determines whether the requirements for obtaining an authorization have been met.

According to the Clean Air Act Section 209 - State Standards, EPA shall grant an authorization under section 209(e)(2), unless the Administrator finds that California:

  • was arbitrary and capricious in its finding that its standards are, in the aggregate, at least as protective of public health and welfare as applicable federal standards;
  • does not need such standards to meet compelling and extraordinary conditions; or
  • California’s standards and accompanying enforcement procedures are not consistent with this section.

EPA’s regulations implementing section 209(e)(2) are at 40 CFR part 1074, subpart B, § 1074.105.

State Adoption of California Standards

The Clean Air Act allows other states to adopt California’s motor vehicle emission standards under section 177. Section 177 requires, among other things, that such standards be identical to the California standards for which a waiver has been granted. States are not required to seek EPA approval under the terms of section 177. EPA issued guidance (CISD-07-16) regarding its cross-border sales policy for California-certified vehicles; this guidance includes a list and map of states that have adopted California standards, specific to the 2008-2010 model years.

The Clean Air Act also allows other states to adopt California’s nonroad vehicle or engine emission standards under section 209(e)(2)(B). Section 209(e)(2)(B) requires, among other things, that such standards be identical to the California standards for which an authorization has been granted. States are not required to seek EPA approval under the terms of section 209(e)(2)(B).
