Supplementary Information

(A) CARB's Waiver Request for its HD Tractor-Trailer GHG Regulation

CARB's June 20, 2013, letter to the Acting Administrator presents EPA with CARB's HD Tractor-Trailer GHG Regulation as adopted in 2008 and amended in 2010 and 2012. (1) CARB is seeking a waiver for those elements of the HD Tractor-Trailer GHG Regulation applicable to new 2011 through 2013model year (MY) Class 8 tractors equipped with integrated sleeper berths (sleeper cab tractors), and to new 2011 and subsequent MY dry-van and refrigerated-van trailers that are pulled by such tractors on California highways.

(B) Scope of Preemption and Criteria for a Waiver Under the Clean Air Act

Section 209(a) of the Clean Air Act, as amended (“Act”), 42 U.S.C. 7543(a), provides:

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.

Section 209(b) of the Act requires the Administrator, after notice and opportunity for public hearing, to waive application of the prohibitions of section 209(a) for any state that 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. California is the only state that is qualified to seek and receive a waiver under section 209(b). EPA must grant a waiver unless the Administrator finds that (A) the determination of the state is arbitrary and capricious, (B) the state does not need the state standards to meet compelling and extraordinary conditions, or (C) the state standards and accompanying enforcement procedures are not consistent with section 202(a) of the Act. Previous decisions granting waivers of federal preemption for motor vehicles have maintained that state standards are inconsistent with section 202(a) if there is inadequate lead time to permit the development of the necessary technology giving appropriate consideration to the cost of compliance within that time period or if the federal and state test procedures impose inconsistent certification procedures. (2)

(C) Request for Comment

EPA invites comment on CARB's request for a waiver of its HD Tractor-Trailer GHG Regulation with regard to those regulatory provisions pertaining to new tractors (2011 through 2013 model years) and new trailers (2011 and subsequent model years) under the following three criteria: Whether (a) California's determination that its motor vehicle emission standards are, in the aggregate, at least as protective of public health and welfare as applicable federal standards is arbitrary and capricious, (b) California needs such standards to meet compelling and extraordinary conditions, and (c) California's standards and accompanying enforcement procedures are consistent with section 202(a) of the Clean Air Act.

Procedures for Public Participation

The Agency will make a verbatim record of the proceedings. Interested parties may arrange with the reporter at the hearing to obtain a copy of the transcript at their own expense. EPA will keep the record open until October 18, 2013. Upon expiration of the comment period, the Administrator will render a decision on CARB's request based on the record of the public hearing, relevant written submissions, and other information that she deems pertinent.

Persons with comments containing proprietary information must distinguish such information from other comments to the greatest possible extent and label it as “Confidential Business Information” (CBI). If a person making comments wants EPA to base its decision in part on a submission labeled CBI, then a non-confidential version of the document that summarizes the key data or information should be submitted for the public docket. To ensure that proprietary information is not inadvertently placed in the docket, submissions containing such information should be sent directly to the contact person listed above and not to the public docket. Information covered by a claim of confidentiality will be disclosed by EPA only to the extent allowed and by the procedures set forth in 40 CFR part 2. If no claim of confidentiality accompanies the submission when EPA receives it, EPA will make it available to the public without further notice to the person making comments.

(1) See Title 17, California Code of Regulations (CCR) sections 95300 through 95312.

(2) To be consistent, the California certification procedures need not be identical to the federal certification procedures. California procedures would be inconsistent, however, if manufacturers would be unable to meet the state and the federal requirements with the same test vehicle in the course of the same test. See, e.g., 43 FR 32182 (July 25, 1978).
