Statutory Sections Relevant to the Regulation of New Mobile-Source Emissions
[CLEAN AIR ACT SECTION 209 (42 U.S.C. 7543)]
Sec. 209.
(a) No State or any political subdivision thereof shall adopt or attempt to enforce any standard relating to the control of emissions from new motor vehicles or new motor vehicle engines subject to this part. No State shall require certification, inspection, or any other approval relating to the control of emissions from any new motor vehicle or new motor vehicle engine as condition precedent to the initial retail sale, titling (if any), or registration of such motor vehicle, motor vehicle engine, or equipment.
(b)(1) The Administrator shall, after notice and opportunity for public hearing, waive application of this section to any State which has adopted standards (other than crankcase emission standards) for the control of emissions from new motor vehicles or new motor vehicle engines prior to March 30, 1966, if the State determines that the State standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. No such waiver shall be granted if the Administrator finds that-
(A) the determination of the State is arbitrary and capricious,
(B) such State does not need such State standards to meet compelling and extraordinary conditions, or
(C) such State standards and accompanying enforcement procedures are not consistent with section 202(a) of this part.
(2) If each State standard is at least as stringent as the comparable applicable Federal standard, such State standard shall be deemed to be at
least as protective of health and welfare as such Federal standards for purposes of paragraph (1).
(3) in the case of any new motor vehicle or new motor vehicle engine to which State standards apply pursuant to a waiver granted under paragraph (1), compliance with such State standards shall be treated as compliance with applicable Federal standards for purposes of this title.
(c) Whenever a regulation with respect to any motor vehicle part or motor vehicle engine part is in effect under section 207(a)(2), no State or political subdivision thereof shall adopt or attempt to enforce any standard or any requirement of certification, inspection, or approval which relates to motor vehicle emissions and is applicable to the same aspect of such part. The preceding sentence shall not apply in the case of a State with respect to which a waiver is in effect under subsection (b).
(d) Nothing in this part shall preclude or deny to any State or political subdivision thereof the right otherwise to control, regulate, or restrict the use, operation, or movement of registered or licensed motor vehicles.
(e) Nonroad Engines or Vehicles.-
(1) Prohibition on certain state standards.- No State or any political subdivision thereof shall adopt or attempt to enforce any standard or other requirement relating to the control of emissions from either of the following new nonroad engines or nonroad vehicles subject to regulation under this Act-
(A) New engines which are used in construction equipment or vehicles or used in farm equipment or vehicles and which are smaller than 175 horsepower.
(B) New locomotives or new engines used in locomotives. Subsection (b) shall not apply for purposes of this paragraph.
(2) Other nonroad engines or vehicles.-
(A) In the case of any nonroad vehicles or engines other than those referred to in subparagraph (A) or (B) of paragraph (1), the Administrator shall, after notice and opportunity for public hearing, authorize California to adopt and enforce standards and other requirements relating to the control of emissions from such vehicles or engines if California determines that California standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. No such authorization shall be granted if the Administrator finds that-
(i) the determination of California is arbitrary and capricious,
(ii) California does not need such California standards to meet compelling and extraordinary conditions, or
(iii) California standards and accompanying enforcement procedures are not consistent with this section.
(B) Any State other than California which has plan provisions approved under part D of title I may adopt and enforce, after notice to the Administrator, for any period, standards relating to control of emissions from nonroad vehicles or engines (other than those referred to in subparagraph (A) or (B) of paragraph (1)) and take such other actions as are referred to in subparagraph (A) of this paragraph respecting such vehicles or engines if-
(i) such standards and implementation and enforcement are identical, for the period concerned, to the California standards authorized by the Administrator under subparagraph (A), and
(ii) California and such State adopt such standards at least 2 years before commencement of the period for which the standards take effect. The Administrator shall issue regulations to implement this subsection.
[CLEAN AIR ACT SECTION 177 (42 U.S.C. 7507)]
Sec. 177. Notwithstanding section 209(a), any State which has plan provisions approved under this part may adopt and enforce for any model year standards relating to control of emissions from new motor vehicles or new motor vehicle engines and take such other actions as are referred to in section 209(a) respecting such vehicles if-
(1) such standards are identical to the California standards for which a waiver has been granted for such model year, and
(2) California and such State adopt such standards at least two years before commencement of such model year (as determined by regulations of the Administrator). Nothing in this section or in title II of this Act shall be construed as authorizing any such State to prohibit or limit, directly or indirectly, the manufacture or sale of a new motor vehicle or motor vehicle engine that is certified in California as meeting California standards, or to take any action of any kind to create, or have the effect of creating, a motor vehicle or motor vehicle engine different than a motor vehicle or engine certified in California under California standards (a “third vehicle”) or otherwise create such a “third vehicle.”
[P.L. 108-199 DIVISION G]
Sec. 428. Regulation of Small Engines.
(a) In considering any request from California to authorize the State to adopt or enforce standards of other requirements relating to the control of emissions from new non-road spark-ignition engines smaller than 50 horsepower, the Administrator shall give appropriate consideration to safety factors (including the potential increased risk of burn or fire) associated with compliance with the California standard.
(b) Not later than December 1, 2004, the Administrator of the Environmental Protection Agency shall propose regulations under the Clean Air Act that shall contain standards to reduce emissions from new nonroad spark-ignition engines smaller than 50 horsepower. Not later than December 31, 2005, the Administrator shall publish in the Federal Register final regulations containing such standards.
(c) No State or any political subdivision thereof may adopt or attempt to enforce any standard or other requirement applicable to spark ignition engines smaller than 50 horsepower.
(d) Exception for California.--The prohibition in subsection (e) does not apply to or restrict in any way the authority granted to California under section 209(e) of the Clean Air Act (42 U.S.C. 7543(e)).
(e) Exception for Other States.--The prohibition in subsection (c) does not apply to or restrict the authority of any State under section 209(e)(2)(B) of the Clean Air Act (42 U.S.C. 7543(e)(2)(B)) to enforce standards or other requirements that were adopted by that State before September 1, 2003.
