Notice of Opportunity for Public Hearing and Comment.


The California Air Resources Board (CARB) has notified EPA that it has adopted emission standards for fleets that operate nonroad, diesel fueled equipment with engines 25 horsepower (hp) and greater. By letter dated August 12, 2008, CARB submitted a request seeking EPA authorization, pursuant to section 209(e) of the Clean Air Act (CAA), 42 U.S.C. 7543(e), of its regulation requiring such fleets to meet fleet average emissions standards for oxides of nitrogen and particulate matter, or, alternatively, to comply with best available control technology requirements for the vehicles in those fleets. This notice announces that EPA has tentatively scheduled a public hearing concerning California's request and that EPA is accepting written comment on the request.


EPA has tentatively scheduled a public hearing concerning CARB's request on October 27, 2008, beginning at 10 a.m. EPA will hold a hearing only if a party notifies EPA by October 20, 2007 expressing its interest in presenting oral testimony. If EPA does not receive a request for a public hearing, then EPA will not hold a hearing, and, instead, consider CARB's request based on written submissions to the docket. Any party may submit written comments by November 28, 2008.

Background and Discussion: Section 209(e)(1) of the Act addresses the permanent preemption of any State, or political subdivision thereof, from adopting or attempting to enforce any standard or other requirement relating to the control of emissions for certain new nonroad engines or vehicles. Section 209(e)(2) of the Act requires the Administrator to grant California authorization to enforce state standards for new nonroad engines or vehicles which are not listed under section 209(e)(1), subject to certain restrictions. On July 20, 1994, EPA promulgated a regulation that sets forth, among other things, the criteria, as found in section 209(e)(2), by which EPA must consider any California authorization requests for new nonroad engines or vehicle emission standards (section 209(e) rules).[1]

Start Printed Page 58586

Section 209(e)(2) requires the Administrator, after notice and opportunity for public hearing, to authorize California to enforce standards and other requirements relating to emissions control of new engines not listed under section 209(e)(1). The section 209(e) rule and its codified regulations [2] formally set forth the criteria, located in section 209(e)(2) of the Act, by which EPA must grant California authorization to enforce its new nonroad emission standards and they are as follows:

(a) The Administrator shall grant the authorization if California determines that California standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards.

(b) The authorization shall not be granted if the Administrator finds that:

(1) The determination of California is arbitrary and capricious;

(2) California does not need such California standards to meet compelling and extraordinary conditions; or

(3) California standards and accompanying enforcement procedures are not consistent with section 209.

As stated in the preamble to the section 209(e) rule, EPA has interpreted the requirement “California standards and accompanying enforcement procedures are not consistent with section 209” to mean that California standards and accompanying enforcement procedures must be consistent with section 209(a), section 209(e)(1), and section 209(b)(1)(C), as EPA has interpreted that subsection in the context of motor vehicle waivers.[3] In order to be consistent with section 209(a), California's nonroad standards and enforcement procedures must not apply to new motor vehicles or new motor vehicle engines. Secondly, California's nonroad standards and enforcement procedures must be consistent with section 209(e)(1), which identifies the categories permanently preempted from state regulation.[4] California's nonroad standards and enforcement procedures would be considered inconsistent with section 209 if they applied to the categories of engines or vehicles identified and preempted from State regulation in section 209(e)(1).

Finally, because California's nonroad standards and enforcement procedures must be consistent with section 209(b)(1)(C), EPA reviews nonroad authorization requests under the same “consistency” criteria that are applied to motor vehicle waiver requests. Under section 209(b)(1)(C), the Administrator shall not grant California a motor vehicle waiver if he finds that California “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 stated 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.[5]

CARB has submitted to EPA its In-Use Off-Road Diesel-Fueled Fleets regulation adopted at its July 26, 2007 public hearing (by Resolution 07-19) and subsequently modified after supplemental public comment by CARB's Executive Officer by the In-Use Regulation in Executive Order R-08-002 on April 4, 2008 (these regulations are codified at title 13, California Code of Regulations sections 2449 through 2449.3). CARB's regulations require fleets that operate nonroad, diesel-fueled equipment with engines 25 hp and greater to meet fleet average emission standards for oxides of nitrogen and particulate matter. Alternatively, the regulations require the vehicles in those fleets to comply with best available control technology requirements. Compliance for the largest fleets (fleets with a total maximum power greater than 5000 hp) is required beginning March 1, 2010, for medium-sized fleets (greater than 2500 hp through 5000 hp) beginning March 1, 2013, and for small fleets (up to 2500 hp) beginning March 1, 2015.

Please provide comment whether (a) CARB's determination that its standards, in the aggregate, 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 209 of the 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 not 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 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 November 28, 2008. Following the expiration of the comment period, the Administrator will render a decision on CARB's request based on the record of the public hearing, if any, relevant written submissions, and other information that he deems pertinent.

Persons with comments containing proprietary information must distinguish such information from other comments to the great 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 pubic 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.  Section 209(e)(1) states, in part: 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.

EPA's regulation was published at 59 FR 36969 (July 20, 1994), and regulations set forth therein, 40 CFR Part 85, Subpart Q, §§ 85.1601 et seq. A new rule, signed on September 4, 2008, moves these provisions to 40 CFR Part 1074.

5.  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 both the state and the Federal requirement with the same test vehicle in the course of the same test. See, e.g., 43 FR 32182 (July 25, 1978).
