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.
- 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.
- 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) are at 40 CFR Part 1074.
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.
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).
40 CFR § 1074.110(b) provides that states and localities, other than the State of California, may not adopt or attempt to enforce any standard or other requirement applicable to the control of emissions from spark-ignition engines smaller than 50 horsepower, except standards or other requirements that were adopted by that state before September 1, 2003.
