# SUPPLEMENTARY INFORMATION:

## (A) Background and Discussion 

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). The Administrator must grant a waiver unless he finds that (A) the determination of the state is arbitrary and capricious, (B) the state does not need the 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. 

                    CARB's September 22, 2006, letter to the Administrator notified EPA that it had formally adopted Malfunction and Diagnostic System Requirements for 2010 and Subsequent Model-Year Heavy-Duty Engines (also known as On-                          ( print page 8728)                        Board Diagnostics or OBD) on December 28, 2005. This regulation can be found at title 13, California Code of Regulations (CCR), section 1971.1.                 

Please provide comment as to whether (a) California's determination that its regulations as referenced in its September 22, 2006, request letter, are at least as protective of public health and welfare as applicable federal standards is arbitrary and capricious, (b) California needs separate 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:

In recognition that public hearings are designed to give interested parties an opportunity to participate in this proceeding, there are no adverse parties as such. Statements by participants will not be subject to cross-examination by other participants without special approval by the presiding officer. The presiding officer is authorized to strike from the record statements that he or she deems irrelevant or repetitious and to impose reasonable time limits on the duration of the statement of any participant. 

If a hearing is held, the Agency will make a verbatim record of the proceedings. Interested parties may arrange with the reporter at the hearing(s) to obtain a copy of the transcript at their own expense. Regardless of whether a public hearing is held, EPA will keep the record open until May 8, 2007. Upon expiration of the comment period, the Administrator will render a decision on CARB's request based on the record of the public hearing(s), if any, relevant written submissions, and other information that he deems pertinent. All information will be available for inspection at EPA Air Docket. (EPA-HQ-OAR-2006-0844) and in the edocket as noted above. 

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 nonconfidential 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. 

Dated: February 21, 2007. 

William L. Wehrum, 

Acting Assistant Administrator, Office of Air and Radiation.
