          - [FRL-9919-57-OAR]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice.

# SUMMARY:

The California Air Resources Board (CARB) has notified the Environmental Protection Agency (EPA) that it has adopted amendments to its large spark-ignited engines regulation (LSI amendments). By letter dated June 2, 2014, CARB asked that EPA either confirm that the LSI amendments (adopted in 2008 and 2010) are within the scope of prior authorizations or that EPA issue a full authorization for those LSI amendments found not to be within the scope of prior authorizations, pursuant to section 209(e) of the Clean Air Act (CAA or Act). This notice announces that EPA has tentatively scheduled a public hearing to consider California's authorization request for the LSI amendments, and that EPA is now accepting written comment on the request.

# DATES:

EPA has tentatively scheduled a public hearing concerning CARB's request on January 14, 2015, at 10 a.m. ET. EPA will hold a hearing only if any party notifies EPA by December 15, 2014, to express interest in presenting the agency with oral testimony. Parties that wish to present oral testimony at the public hearing should provide written notice to David Dickinson at the email address noted below. If EPA receives a request for a public hearing, that hearing will be held at the William Jefferson Clinton Building (North), Room 5530, 1200 Pennsylvania Avenue NW., Washington, DC 20460. If EPA does not receive a request for a public hearing, then EPA will not hold a hearing, and instead will consider CARB's request based on written submissions to the docket. Any party may submit written comments until February 16, 2015.

Any person who wishes to know whether a hearing will be held may call David Dickinson at (202) 343-9256 on or after December 17, 2014.

# SUPPLEMENTARY INFORMATION:

## I. California's LSI Regulations

                    CARB promulgated its first LSI regulations, applicable to new LSI engines, in 1999 and they remained unchanged until the 2008 amendments.[1]                                          EPA authorized the LSI regulations, on May 15, 2006.[2]                                          The 1999 LSI regulations established exhaust emission standards and associated test procedures for LSI engines based upon engine displacements. The exhaust emission standards applicable to 2002 and subsequent model years (MYs) with displacements up to one liter were identical to the emission standards applicable to California small off-road engines (SORE) with engines greater than or equal to 225 cubic centimeters and have remained unchanged except CARB subsequently adopted more stringent exhaust emission standards for engines greater than 225 cubic centimeters.[3]                                          CARB adopted its initial off-road LSI fleet operator regulations on May 25, 2006 (Fleet Operator Regulations).[4]                                          The Fleet Operator Regulations are designed to address the hydrocarbon and nitrogen oxide emissions from existing LSI engines operating in California and require fleets to meet certain fleet average emission level standards.                

CARB adopted the 2008 LSI amendments on November 21, 2008. The 2008 LSI amendments create two new engine categories below one liter displacement, with new more stringent exhaust and evaporative emission standards applicable to new engines, and provide clarification as to when CARB's off-road sport or utility regulations apply to certain LSI engines.

CARB adopted the 2010 LSI amendments on December 17, 2010. These amendments are designed to provide compliance flexibility which will allow operators to reduce their compliance costs while retaining the emission benefits associated with the original regulations.

By letter dated June 2, 2014, CARB submitted a request to EPA pursuant to section 209(e) of the CAA for authorization of its 2008 and 2010 LSI amendments. CARB seeks EPA's confirmation that these amendments fall within the scope of EPA's previous authorization, or, in the alternative, a full authorization.

## II. Clean Air Act Nonroad Engine and Vehicle Authorizations

                    Section 209(e)(1) of the CAA prohibits states and local governments from adopting or attempting to enforce any standard or requirement relating to the control of emissions from new nonroad vehicles or engines. The Act also preempts states from adopting and enforcing standards and other requirements related to the control of emissions from non-new nonroad engines or vehicles. Section 209(e)(2), however, requires the Administrator, after notice and opportunity for public hearing, to 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. However, EPA shall not grant such authorization if it finds that (1) the                           ( print page 69847)                        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 [CAA section 209].[5]                                          In addition, other states with air quality attainment plans may adopt and enforce such regulations if the standards, and implementation and enforcement procedures, are identical to California's standards. On July 20, 1994, EPA promulgated a rule that sets forth, among other things, regulations providing the criteria, as found in section 209(e)(2), which EPA must consider before granting any California authorization request for new nonroad engine or vehicle emission standards.[6]                                          EPA revised these regulations in 1997.[7]                                          As stated in the preamble to the 1994 rule, EPA has historically interpreted the section 209(e)(2)(iii) “consistency” inquiry to require, at minimum, that California standards and enforcement procedures 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 section 209(b) motor vehicle waivers).[8] 

                    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. To be consistent with section 209(e)(1), California's nonroad standards and enforcement procedures must not attempt to regulate engine categories that are permanently preempted from state regulation. To determine consistency with section 209(b)(1)(C), EPA typically reviews nonroad authorization requests under the same “consistency” criteria that are applied to motor vehicle waiver requests. Pursuant to section 209(b)(1)(C), the Administrator shall not grant California a motor vehicle waiver if she finds that California “standards and accompanying enforcement procedures are not consistent with section 202(a)” of the Act. Previous decisions granting waivers and authorizations have noted that state standards and enforcement procedures are inconsistent with section 202(a) if: (1) There is inadequate lead time to permit the development of the necessary technology giving appropriate consideration to the cost of compliance within that time, or (2) the Federal and state testing procedures impose inconsistent certification requirements.[9] 

                    If California amends regulations that EPA has already authorized, California can seek EPA confirmation that the amendments are within the scope of the previous authorization. A within-the-scope confirmation, without a full authorization review, is permissible if three conditions are met.[10]                                          First, the amended regulations must not undermine California's determination that its standards, in the aggregate, are as protective of public health and welfare as applicable Federal standards. Second, the amended regulations must not affect consistency with section 202(a) of the Act. Third, the amended regulations must not raise any “new issues” affecting EPA's prior authorizations.                

## III. EPA's Request for Comments

As stated above, EPA is offering the opportunity for a public hearing, and is requesting written comment on issues relevant to a within-the-scope analysis. Specifically, we request comment on whether California's LSI amendments: (a) Undermine California's previous determination that its standards, in the aggregate, are at least as protective of public health and welfare as comparable Federal standards; (b) affect the consistency of California's requirements with section 209 of the Act; or (c) raise any other new issues affecting EPA's previous waiver or authorization determinations.

Should any party believe that the amendments are not within the scope of the previous authorization, EPA also requests comment on whether the LSI amendments meet the criteria for a full authorization. Specifically, we request comment on: (a) Whether 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) whether California needs such standards to meet compelling and extraordinary conditions; and (c) whether California's standards and accompanying enforcement procedures are consistent with section 209 of the Act.

## IV. Procedures for Public Participation

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 February 16, 2015. Upon expiration of the comment period, the Administrator will render a decision on CARB's request based on the record from the public hearing, if any, all relevant written submissions, and other information that she deems pertinent. All information will be available for inspection at the EPA Air Docket No. EPA-HQ-OAR-2014-0533.

                    Persons with comments containing proprietary information must distinguish such information from other comments to the greatest extent possible and label it as “Confidential Business Information” (“CBI”). If a person making comments wants EPA to base its decision on a submission labeled as CBI, then a non-confidential version of the document that summarizes the key data or information should be submitted to the public docket. To ensure that proprietary information is not inadvertently placed in the public 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 according to the procedures set forth in 40 CFR part 2.                           ( print page 69848)                        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.

5.                             EPA's review of California regulations under section 209 is not a broad review of the reasonableness of the regulations or its compatibility with all other laws. Sections 209(b) and 209(e) of the Clean Air Act limit EPA's authority to deny California requests for waivers and authorizations to the three criteria listed therein. As a result, EPA has consistently refrained from denying California's requests for waivers and authorizations based on any other criteria. In instances where the U.S. Court of Appeals has reviewed EPA decisions declining to deny waiver requests based on criteria not found in section 209(b), the Court has upheld and agreed with EPA's determination.                         *See Motor and Equipment Manufacturers Ass'n*                         v.                         *Nichols,*                         142 F.3d 449, 462-63, 466-67 (D.C.
