  6. Background

    Under the Clean Air Act (``Act'' or CAA), the EPA establishes national ambient air quality standards (NAAQS) to protect public health and welfare, and has established such ambient standards for a number of pervasive air pollutants including ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, lead and particulate matter. Under section 110(a)(1) of the CAA, states must submit plans that provide for the implementation, maintenance, and enforcement of the NAAQS within each state. Such plans are referred to as state implementation plans (SIPs) and revisions to those plans are referred to as SIP revisions. Section 110(a)(2) of the CAA sets forth the content requirements for SIPs. Among the various requirements, SIPs must include enforceable emission limitations and other control measures, means, or techniques as may be necessary or appropriate to meet the applicable requirements of the CAA. CAA section 110(a)(2)(a).

    As a general matter, the CAA assigns mobile source regulation to the EPA through title II of the Act and assigns stationary source regulation and SIP development responsibilities to the states through title I of the Act. In so doing, the CAA preempts various types of state regulation of mobile sources as set forth in section 209(a) (preemption of state emissions standards for new motor vehicles and engines), section 209(e) (preemption of state emissions standards for new and in-use off-road vehicles and engines),\1\ and section 211(c)(4)(A) preemption of state fuel requirements for motor vehicle emission control, i.e., other than California's motor vehicle fuel requirements for motor vehicle emission control--see section 211(c)(4)(B). For certain types of mobile source emission standards, the State of California may request a waiver (for motor vehicles) or authorization (for off-road engines and equipment) for standards relating to the control of emissions and accompanying enforcement procedures. See CAA sections 209(b) (new motor vehicles) and 209(e)(2) (most categories of new and in-use off-road vehicles).

    ---------------------------------------------------------------------------

    \1\ EPA regulations refer to ``nonroad'' vehicles and engines whereas California regulations refer to ``off-road'' vehicles and engines. These terms refer to the same types of vehicles and engines, and for the purposes of this action, we will be using the state's chosen term, ``off-road,'' to refer to such vehicles and engines.

    ---------------------------------------------------------------------------

    Over the years, the California Air Resources Board (CARB) has submitted many requests for waiver or authorization of its standards and other requirements relating to the control of emissions from new on-road and new and in-use off-road vehicles and engines, and the EPA has granted many such requests. For example, the EPA has granted waivers for CARB's Low Emission Vehicle (LEV III) criteria pollutant standards for light- and medium duty vehicles, and has authorized emissions standards for such off-road vehicle categories as commercial harbor craft, and forklifts and other industrial equipment. See 78 FR 2112 (January 9, 2013) (advanced clean cars), 76 FR 77521 (December 13, 2011) (commercial harbor craft), and 77 FR 20388 (April 4, 2012) (forklifts and other industrial equipment).

    Also over the years, CARB has submitted, and the EPA has approved, many local or regional California air district rules regulating stationary source emissions as part of the California SIP. See, generally, 40 CFR 52.220(c). With respect to mobile sources in general, California has submitted, and the EPA has approved, certain specific state regulatory programs, such the in-use, heavy-duty, diesel-fueled truck rule, various fuels regulations, and the vehicle inspection and maintenance program (I/M, also known as ``smog check''). See, e.g., 77 FR 20308 (April 4, 2012) (in-use truck and bus regulation), 75 FR 26653 (May 12, 2010) (revisions to California on-road reformulated gasoline and diesel fuel regulations), and 75 FR 38023 (July 1, 2010) (revisions to California motor vehicle I/M program).

    California relies on these local, regional, and state stationary and mobile source regulations to meet various CAA requirements and includes the corresponding emissions reductions in the various regional air quality plans developed to attain and maintain the NAAQS. The EPA generally allows California to take credit for the corresponding emissions reductions

    Page 69917

    relied upon in the various regional air quality plans because, among other reasons, the regulations are approved as part of the SIP and are thereby federally enforceable as required under CAA section 110(a)(2)(A).

    However, California also relies on emissions reductions from the regulations for which the EPA has previously granted waivers or authorizations, and historically, the EPA has approved regional air quality plans that take credit for emissions reductions from such regulations, notwithstanding the fact that California has not submitted these particular regulations as part of the California SIP.

    The EPA's longstanding practice of approving California plans that rely on emissions reductions from such ``waiver measures,'' notwithstanding the lack of approval as part of the SIP, was challenged in several petitions filed in the Ninth Circuit Court of Appeals. In a recent decision, the Ninth Circuit held in favor of the petitioners on this issue and concluded that CAA section 110(a)(2)(A) requires that all state and local control measures on which SIPs rely to attain the NAAQS be included in the SIP and thereby subject to enforcement by the EPA and members of the general public. See Committee for a Better Arvin v. EPA, 786 F.3d 1169 (9th Cir. 2015).

    In response to the decision in Committee for a Better Arvin v. EPA, CARB submitted a SIP revision on August 14, 2015 consisting of state mobile source regulations that establish standards and other requirements for the control of emissions from various new on-road and new and in-use off-road vehicles and engines for which the EPA has issued waivers or authorizations and that are relied upon by California regional plans to attain and maintain the NAAQS. The EPA is proposing action today under CAA section 110(k) on CARB's August 14, 2015 SIP revision submittal.

  7. The State's Submittal

    1. What regulations did the state submit?

      On August 14, 2015, CARB submitted a SIP revision that included a set of state mobile source regulations for which waivers or authorizations have been granted by the EPA under section 209 of the CAA. The SIP revision consists of the regulations themselves and documentation of the public process conducted by CARB in approving the regulations as part of the California SIP. Table 1 below presents the contents of the SIP revision by mobile source category and provides, for each such category, a listing of the relevant sections of the California Code of Regulations (CCR) that establish standards and other requirements for control of emissions from new or in-use vehicles or engines; the corresponding date of CARB's hearing date or Executive Officer (EO) action through which the regulations or amendments were adopted; and the notice of decision in which the EPA granted a waiver or authorization for the given set of regulations.\2\

      ---------------------------------------------------------------------------

      \2\ CARB's August 14, 2015 SIP submittal included a table that lists the specific sections of the CCR included in the submittal. By email dated October 23, 2015, CARB identified a few typographic errors in the table: (1) 13 CCR sections 2456(d)(3), 2456(d)(5), and 2456(d)(6) (i.e., not sections 2455(d)(3), 2455(d)(5), and 2455(d)(6)) are excluded from the submittal of regulations establishing standards and other requirements for the portable equipment registration program (PERP); (2) 13 CCR section 2485(1)(B) (not just section 2385(1)(A)) is excluded from the submittal of regulations related to truck idling; (3) and 13 CCR section 2474 is to be included in the submittal of regulations related to spark-

      ignition marine engines. See email from Alex Wong, CARB, to Jefferson Wehling, EPA Region IX, dated October 23, 2015.

      ------------------------------------------------------------------------

      It is important to note that CARB has expressly excluded from the August 14, 2015 SIP submittal certain sections or subsections of California code that have been authorized or waived by the EPA under CAA section 209. The excluded provisions pertain to:

      Greenhouse Gas (GHG) exhaust emission standards for 2009 through 2016 Model Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles, and 2017 and subsequent Model Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles; and

      GHG related provisions incorporated in the test procedures. Also, CARB has expressly excluded certain sections or subsections of California code that are not subject to preemption under CAA section 209 and thus not included in the related waiver or authorization by the EPA. These provisions pertain to:

      Fuel requirements;

      Idling restrictions on drivers;

      Opacity standards;

      Daily mass emission limits (from the PERP regulations); and

      Certain labeling and consumer notification requirements.

      Section III.B.4 below provides further discussion of these excluded provisions.

    2. Are there other versions of these regulations?

      As noted previously, the CAA generally assigns to the EPA the responsibility of establishing standards for the control of emissions from mobile sources. However, the State of California was a pioneer in establishing standards for the control of emissions from new motor vehicles, and, in part due to the state's pioneering efforts, Congress established in 1967 a process under which California, alone among the states, would be granted a waiver from preemption (if certain criteria are met) and thereby enforce its own standards and other requirements for the control of emissions from new motor vehicles. In the 1990 CAA Amendments, Congress extended a similar process that had been established under section 209 for new motor vehicles to new and in-use off-road vehicles and engines. See CAA section 209(e)(2). Under the 1990 CAA Amendments, the EPA must authorize California standards for the control of emissions of off-road vehicles and engines if certain criteria are met.

      The first waiver granted was for California's On-Road Emissions Standards for Model Year 1968. (See 33 FR 10160, July 16, 1968.) Since then, there have been dozens of waivers and authorizations granted by the EPA for new and amended CARB mobile source regulations. The EPA's Office of Transportation and Air Quality maintains a Web site that provides a general description of the waiver and authorization process and lists all of the various waivers and authorizations granted by the Agency to CARB over the years. See http://www.epa.gov/otaq/cafr.htm.

      Historically, as noted above, CARB regulations subject to the section 209 waiver or authorization process were not submitted to the EPA as a revision to the California SIP. Thus, for the purposes of the California SIP, there are no previous versions of the rules addressed in today's proposed action.

    3. What is the purpose of the submitted regulations?

      Historically, California has experienced some of the most severe and most persistent air pollution problems in the country. Under the CAA, based on ambient data collected at numerous sites throughout the state, the EPA has designated areas within California as nonattainment areas for the ozone NAAQS and the particulate matter (both PM10 and PM2.5) NAAQS. See, generally, 40 CFR 81.305. California also includes a number of areas that had been designated as nonattainment areas for the carbon monoxide NAAQS that the EPA has redesignated as attainment areas because they have attained the standard and are subject to an approved maintenance plan demonstrating how they will maintain the carbon monoxide standard into the future.

      Mobile source emissions constitute a significant portion of overall emissions of carbon monoxide, volatile organic compounds (VOC), oxides of nitrogen (NOX), sulfur dioxide (SO2) and particulate matter (PM) in the various air quality planning areas within California, and thus, the purpose of CARB's mobile source regulations is to reduce these emissions and thereby reduce ambient concentrations to attain and maintain the NAAQS throughout California.\3\ At elevated levels, ozone and PM harm human health and the environment by contributing to premature mortality, aggravation of respiratory and cardiovascular disease, decreased lung function, visibility impairment, and damage to vegetation and ecosystems.

      ---------------------------------------------------------------------------

      \3\ VOC and NOX are precursors responsible for the formation of ozone, and NOX and SO2 are precursors for fine particulate matter (PM2.5). SO2 belongs to a family of compounds referred to as sulfur oxides (SOX). PM2.5 precursors also include VOC and ammonia. See 40 CFR 51.1000.

      ---------------------------------------------------------------------------

    4. What requirements do the regulations establish?

      Table 3 below describes the applicability of the regulations listed in table 1 above and summarizes some of the key emissions control requirements contained in the rules.

      Source category submitted regulation

      ------------------------------------------------------------------------

      On-Road Passenger Cars, Light-Duty CARB's ``LEV II'' regulations

      Trucks, and Medium-Duty Vehicles establish exhaust and

      (LEV II). evaporative emissions standards

      (and test procedures) for model

      year (MY) 2004 through 2014

      passenger cars, light-duty

      trucks, and medium-duty

      passenger vehicles. The LEV II

      regulations also include the

      adoption of Compliance Assurance

      Program ``CAP 2000'' amendments

      that establish new motor vehicle

      certification and in-use test

      requirements--developed jointly

      with the U.S. Environmental

      Protection Agency--applicable to

      2001 and subsequent model motor

      vehicles. For more information

      about CARB's LEV II regulations,

      see 68 FR 19811 (April 22,

      2003), 70 FR 22034 (April 28,

      2005), and 75 FR 44948 (July 30,

      2010).

      On-Road Passenger Cars, Light-Duty CARB's LEV III and ZEV amendments

      Trucks, and Medium-Duty Vehicles combine the control of criteria

      (LEV III) and Zero Emission Vehicles air pollutants and GHG emissions

      (ZEV). into a single coordinated

      package of requirements for MY

      2015 through 2025 passenger

      cars, light-duty trucks, and

      medium-duty passenger vehicles.

      The requirements amend the

      exhaust and evaporative

      emissions standards, the test

      procedures, and the on-board

      diagnostic system

      specifications. (The standards

      related to GHG emissions are not

      included in the SIP revision

      submittal.) For more information

      about CARB's LEV III and ZEV

      amendments, see 78 FR 2112

      (January 9, 2013).

      On-Road Heavy-Duty Gasoline Engines.. CARB's on-road heavy-duty

      gasoline engine regulations

      establish exhaust emission

      standards for heavy-duty Otto-

      cycle engines and vehicles above

      8,500 pounds gross vehicle

      weight rating (GVWR) for the

      2004, 2005 through 2007, and the

      2008 and subsequent MYs. These

      regulations align each of

      California's exhaust emission

      standards and test procedures

      with its federal counterpart in

      an effort to streamline and

      harmonize the California and

      federal programs. For more

      information about CARB's on-road

      heavy-duty gasoline engine

      regulations, see 75 FR 70237

      (November 17, 2010).

      On-Road Heavy-Duty Diesel Engines.... CARB's On-Road Heavy-Duty Diesel

      Engine regulations establish

      heavy-duty diesel regulations

      for 2007 and subsequent model

      year vehicles and engines (2007

      California Heavy Duty Diesel

      Engine Standards) and related

      test procedures including the

      not-to-exceed (NTE) and

      supplemental steady state tests

      (supplemental test procedures)

      to determine compliance with

      applicable standards. CARB's

      2007 California Heavy Duty

      Diesel Engine Standards

      primarily align California's

      standards and test procedures

      with the federal standards and

      test procedures for 2007 and

      subsequent model year on-road

      heavy-duty vehicles and engines.

      For more information about

      CARB's On-Road Heavy-Duty Diesel

      Engine regulations, see 70 FR

      50322 (August 26, 2005)

      On-Road Motorcycles.................. CARB's regulations establish

      exhaust emissions standards and

      test procedures for new on-road

      motorcycles and motorcycle

      engines. For additional

      information about CARB's

      motorcycle regulations, see 71

      FR 44027 (August 3, 2006).

      On-Road Heavy-Duty Engines--On-Board CARB's HD OBD regulations

      Diagnostic System (HD OBD). establish requirements for

      onboard diagnostic systems (OBD

      systems) that are installed on

      2010 and subsequent model-year

      engines certified for sale in

      heavy-duty applications in

      California. The OBD systems,

      through the use of an onboard

      computer(s), monitor emission

      systems in-use for the actual

      life of the engine and are

      capable of detecting

      malfunctions of the monitored

      emission systems, illuminating a

      malfunction indicator light

      (MIL) to notify the vehicle

      operator of detected

      malfunctions, and storing fault

      codes identifying the detected

      malfunctions. For more

      information about CARB's HD OBD

      regulations, see 77 FR 73459

      (December 10, 2012).

      On-Road Heavy Duty Vehicles--engine As submitted, CARB's truck idling

      or vehicle idle controls. requirements consist of ``New

      engine requirements'' that

      require new California-certified

      2008 and subsequent model year

      on-road diesel engines in

      vehicles with a gross vehicle

      weight rating (GVWR) greater

      than 14,000 pounds (i.e., heavy-

      duty diesel vehicles or

      ``HDDV''s) be equipped with a

      system that automatically shuts

      down the engine after five

      minutes of continuous idling.

      For more information about

      CARB's truck idling

      requirements, see 77 FR 9239

      (February 16, 2012).

      In-Use Diesel-Fueled Transport Establishes in-use performance

      Refrigeration Units (TRUs). standards for diesel-fueled TRUs

      and TRU generator sets operating

      in California, and facilities

      where TRUs operate. In-use TRU

      engines are required, through

      one of the compliance options

      set forth in the regulations

      (e.g., retrofit or replacement),

      to meet specific performance

      standards that vary by

      horsepower range, and that have

      two levels of stringency that

      are phased in over time--the Low

      Emission TRU Standards,

      beginning in 2008, and the Ultra-

      Low Emission TRU Standards

      beginning in 2010. More

      stringent performance standards

      are required at 7-year intervals

      until the Ultra-Low TRU

      standards are met. For more

      information about CARB's in-use

      TRU regulations, see 74 FR 3030

      (January 16, 2009) and 78 FR

      38970 (June 28, 2013).

      Commercial Harbor Craft.............. CARB's commercial harbor craft

      regulations establish emissions

      standards, requirements related

      to control of emissions, and

      enforcement provisions

      applicable to diesel propulsion

      and auxiliary engines on new and

      in-use commercial harbor craft.

      For new harbor craft, each

      propulsion and auxiliary diesel

      engine on the vessel is required

      to be certified to the most

      stringent federal new marine

      engine emission standards for

      that engine's power rating and

      displacement in effect at the

      time of sale, lease, rent, or

      acquisition. The regulation

      imposes additional requirements

      for larger new ferries (with the

      capacity to transport seventy-

      five or more passengers), either

      by using best available control

      technology (``BACT''), or by

      using a federal Tier 4 certified

      propulsion engine. For in-use

      harbor craft, new or in-use

      diesel engines may not be sold,

      offered for sale, leased,

      rented, or acquired unless the

      diesel propulsion or auxiliary

      engines are certified to at

      least the federal Tier 2 or Tier

      3 marine emission standards for

      new engines of the same power

      rating and displacement. In-use

      emission requirements are

      imposed on Tier 0 and Tier 1

      marine engines in ferries,

      excursion vessels, tugboats,

      towboats, push boats, and

      multipurpose harbor craft. Those

      harbor craft are required to

      meet emission limits equal to or

      cleaner than the federal new

      marine engine certification

      standards in effect for the year

      that in-use engine compliance is

      required. For more information

      about CARB's commercial harbor

      craft regulations, see 76 FR

      77521 (December 13, 2011).

      Page 69922

      Off-Road Large Spark-Ignition (LSI) CARB's LSI regulations establish

      Engines. more stringent emissions

      standards for new off-road LSI

      engines (25 hp or greater,

      gasoline- or LPG-powered,

      excluding construction and farm

      equipment) beginning in 2007

      (increasing in stringency in

      2010), and in-use fleet

      requirements for forklifts and

      other industrial equipment with

      LSI engines. The fleet average

      in-use emission standards apply

      to operators of large- and

      medium-sized fleets of

      forklifts, sweepers/scrubbers,

      airport ground supported

      equipment (GSE), and industrial

      two tractors with engine

      displacements of greater than

      one liter. For more information

      about CARB's LSI regulations,

      see 77 FR 20388 (April 4, 2012).

      Auxiliary Diesel Engines on Ocean- CARB's ``At-Berth'' regulation

      Going Vessels. contains requirements that

      apply, with limited exceptions,

      to any person who owns or

      operates any container vessel,

      passenger vessel, or

      refrigerated cargo vessel that

      visits any of six specified

      California ports. It also

      contains requirements that

      affect any person who owns or

      operates those ports or

      terminals located at them.

      CARB's At-Berth regulation

      requires fleets of container

      vessels, passenger vessels and

      refrigerated cargo vessels to

      either: (1) Limit the amount of

      time they operate their

      auxiliary diesel engines by

      connecting to shore power for

      most of a vessel's stay at port

      (``Shore Power Option''); or (2)

      achieve equivalent emission

      reductions by employing other

      emission control techniques

      (``Equivalent Emission Reduction

      Option''). Fleet operators who

      elect the Shore Power Option are

      required to obtain the power

      that would otherwise be provided

      by a vessel's auxiliary engines

      by connecting to shore power for

      a percentage of the fleet's

      annual port visits. The required

      percentage of shore power

      connected port visits increases

      over the life of the regulation.

      Specifically, fifty percent of a

      fleet's total visits must be

      connected to shore power by

      2014, followed by seventy

      percent by 2017, and eighty

      percent by 2020. For more

      information about CARB's At-

      Berth regulation, see 76 FR

      77515 (December 13, 2011).

      In-Use Off-Road Diesel Fueled Fleets. CARB's In-Use Off-Road Diesel-

      Fueled Fleets Regulation applies

      to fleets with off-road

      compression-ignition vehicles or

      equipment greater than 25

      horsepower. The regulation takes

      effect beginning as early as

      2014, depending on fleet size.

      It requires fleet operators to

      meet a progressively more

      stringent combined PM and NOX

      standard, or to reduce emissions

      through technology upgrades such

      as retrofit or replacement. For

      more information about CARB's In-

      Use Off-Road Diesel-Fueled

      Fleets Regulation, see 78 FR

      58090 (September 20, 2013).

      Mobile Cargo Handling Equipment (CHE) CARB's mobile CHE regulation sets

      performance standards for

      engines equipped in newly

      purchased, leased, or rented

      (collectively known as ``newly

      acquired''), as well as in-use,

      mobile cargo handling equipment

      used at ports or intermodal rail

      yards in California. The

      standards vary depending on the

      type of vehicle, whether the

      In-Use Portable Diesel-Fueled Engines CARB's PDE regulation establishes

      (PDE). requirements for in-use portable

      diesel-fueled engines 50 brake-

      horsepower (hp) and greater.

      Specifically, starting on

      January 1, 2010, all portable

      engines in California must be

      certified to meet a federal or

      California standard for newly

      manufactured off-road engines.

      More stringent requirements

      apply beginning on January 1,

      2020. Fleets of portable engines

      must comply with increasingly

      more stringent weighted PM

      emission fleet averages that

      apply on three different

      deadlines (January 1, 2013,

      January 1, 2017, and January 1,

      2020). For more information

      Portable Equipment Registration PERP is a voluntary statewide

      Program (PERP). program that enables

      registration of off-road engines

      and equipment that operate at

      multiple locations across

      California, so that the engine

      and equipment owners can operate

      throughout California without

      obtaining permits from local air

      pollution control districts. The

      PERP sets out four general

      requirements applicable to all

      registered equipment: (1)

      Registered equipment may not

      operate in a manner that causes

      a nuisance; (2) registered

      equipment may not interfere with

      attainment of national or state

      ambient air quality standard;

      (3) registered equipment many

      not cause an exceedance of an

      ambient air quality standard;

      and (4) owners of registered

      equipment must provide notice

      and comply with requirements for

      prevention of significant

      deterioration if it would

      constitute a major modification

      of that source. The PERP also

      has specific requirements for

      both registered engines and

      certain types of equipment

      units. For more information

      about CARB's PERP regulations,

      standards and test procedures

      for OHRVs. The regulations also

      establish a ``red tag'' program

      under which OHRVs not meeting

      the applicable emissions

      standards could be certified

      subject to use restrictions

      (i.e., use in specified areas

      during specified times of the

      year). For more information

  8. EPA's Evaluation and Proposed Action

    1. How is the EPA evaluating the regulations?

      The EPA has evaluated the submitted regulations discussed above against the applicable procedural and substantive requirements of the CAA for SIPs and SIP revisions and has concluded that they meet all of the applicable requirements. Generally, SIPs must include enforceable emission limitations and other control measures, means, or techniques, as well as schedules and timetables for compliance, as may be necessary to meet the requirements of the Act see CAA section 110(a)(2)(A); must provide necessary assurances that the state will have adequate personnel, funding, and authority under state law to carry out such SIP (and is not prohibited by any provision of federal or state law from carrying out such SIP) see CAA section 110(a)(2)(E); must be adopted by a state after reasonable notice and public hearing see CAA section 110(l), and must not interfere with any applicable requirement concerning attainment and reasonable further progress, or any other applicable requirement of the Act see CAA section 110(l).\4\

      ---------------------------------------------------------------------------

      \4\ CAA section 193, which prohibits any pre-1990 SIP control requirement relating to nonattainment pollutants in nonattainment areas from being modified unless the SIP is revised to insure equivalent or greater emission reductions of such air pollutants, does not apply to these regulations because they would be new to the California SIP, and thus, do not constitute an amendment to a pre-

      1990 SIP control requirement.

      ---------------------------------------------------------------------------

    2. Do the state regulations meet CAA SIP evaluation criteria?

      1. Did the state provide adequate public notification and comment periods?

      Under CAA section 110(l), SIP revisions must be adopted by the state, and the state must provide for reasonable public notice and hearing prior to adoption. In 40 CFR 51.102(d), we specify that reasonable public notice in this context refers to at least 30 days.

      All of the submitted regulations have gone through extensive public comment processes including CARB's workshop and hearing processes prior to state adoption of each rule. Also, the EPA's waiver and authorization processes provide an opportunity for the public to request public hearings to present information relevant to the EPA's consideration of CARB's request for waiver or authorization under section 209 of the CAA and to submit written comment.

      In addition, on June 19, 2015, CARB published a notice of public meeting to be held on July 23, 2015 to consider adoption and submittal of the adopted regulations for which the EPA has granted waivers or authorization as a revision to the California SIP. CARB held the public hearing on July 23, 2015. No written comments were submitted to CARB in connection with the proposed SIP revision, and no public comments were made at the public hearing. CARB adopted the SIP revision at the July 23, 2015 Board Hearing (Board Resolution 15-40), and submitted the relevant mobile source regulations to the EPA on August 14, 2015 along with evidence of the public process conducted by CARB in adopting the SIP revision. We conclude that CARB's August 14, 2015 SIP revision submittal meets the applicable procedural requirements for SIP revisions under the CAA section 110(l) and 40 CFR 51.102.

      2. Does the state have adequate legal authority to implement the regulations?

      CARB has been granted both general and specific authority under the California Health & Safety Code (H&SC) to adopt and implement these regulations. California H&SC sections 39600 (``Acts required'') and 39601 (``Adoption of regulation; Conformance to federal law'') confer on CARB the general authority and obligation to adopt regulations and measures necessary to execute CARB's powers and duties imposed by state law. California H&SC sections 43013(a) and 43018 provide broad authority to achieve the maximum feasible and cost-effective emission reductions from all mobile source categories. Regarding in-use motor vehicles, California H&SC sections 43600 and 43701(b), respectively, grant CARB authority to adopt emission standards and emission control equipment requirements. Further, California H&SC section 39666 gives CARB authority to adopt airborne toxic control measures to reduce emissions of toxic air contaminants from new and in-use non-vehicular sources.

      As a general matter, as noted above, the CAA assigns mobile source regulation to the EPA through title II of the Act and assigns stationary source regulation and SIP development responsibilities to the states through title I of the Act. In so doing, the CAA preempts various types of state regulation of mobile sources as set forth in section 209(a) (preemption of state emissions standards for new motor vehicles and engines), section 209(e) (preemption of state emissions standards for new and in-use nonroad vehicles and engines) and section 211(c)(4)(A) preemption of state fuel requirements for motor vehicles, i.e., other than California's motor vehicle fuel requirements for motor vehicle emission control--section 211(c)(4)(B). For certain types of mobile source standards, the State of California may request a waiver (for motor vehicles) or authorization (for off-road vehicles or engines) for standards relating to the control of emissions and accompanying enforcement procedures. See CAA sections 209(b) (new motor vehicles) and 209(e)(2) (most categories of new and in-use off-road vehicles).

      The mobile source regulations that are the subject of today's proposed rule are those for which California has sought a waiver or authorization and for which the EPA has granted such waiver or authorization and thus the regulations proposed for approval today are not preempted under the CAA.\5\ For additional information regarding California's motor vehicle emission standards, please see the EPA's ``California Waivers and Authorizations'' Web page at URL address: http://www.epa.gov/otaq/cafr.htm. This Web site also lists relevant Federal Register notices that have been issued by the EPA is response to California waiver and authorization requests.

      ---------------------------------------------------------------------------

      \5\ We recognize that our authorization (78 FR 58090, September 20, 2013) for CARB's in-use off-road diesel-fueled fleet regulations has been challenged in both the D.C. Circuit and Ninth Circuit Court of Appeals. See Dalton Trucking, Inc. v. EPA (D.C. Cir., No 13-1283) and Dalton Trucking, Inc. v. EPA (9th Cir., No. 13-74019). The D.C. Circuit will hear oral arguments in the case on November 9, 2015. (The Ninth Circuit is holding the cased in abeyance pending a decision by the D.C. Circuit concerning jurisdiction.) An adverse decision from the D.C. Circuit or Ninth Circuit that remands or vacates our authorization of CARB's in-use off-road diesel-fueled fleet regulations will prompt reconsideration of our approval of the regulations as part of the SIP because, absent authorization, CARB will be prohibited from enforcing the regulations and thus will no longer be able to provide the necessary assurances called for in CAA section 110(a)(2)(E) for the subject regulations.

      ---------------------------------------------------------------------------

      In addition, the EPA is unaware of any non-CAA legal obstacle to CARB's enforcement of the regulations and thus we conclude that the state has provided the necessary assurances that the state has adequate authority under state law to carry out the SIP revision (and is not prohibited by any provision of federal or state law from carrying out such SIP) and thereby meets the requirements of CAA section 110(a)(2)(E) with respect to legal authority.

      3. Are the regulations enforceable as required under CAA section 110(a)(2)?

      We have evaluated the enforceability of the submitted mobile source

      Page 69924

      regulations with respect to applicability and exemptions; standard of conduct and compliance dates; sunset provisions; discretionary provisions; and test methods, recordkeeping and reporting,\6\ and have concluded for the reasons given below that the proposed regulations would be enforceable for the purposes of CAA section 110(a)(2).

      ---------------------------------------------------------------------------

      \6\ These concepts are discussed in detail in an EPA memorandum from J. Craig Potter, EPA Assistant Administrator for Air and Radiation, et al., titled ``Review of State Implementation Plans and Revisions for Enforceability and Legal Sufficiency,'' dated September 23, 1987.

      ---------------------------------------------------------------------------

      First, with respect to applicability, we find that the submitted regulations would be sufficiently clear as to which persons and which vehicles or engines are affected by the regulations. See, e.g., 13 CCR section 2430 (applicability provision for off-road LSI engine emission standard regulation); 13 CCR section 2449(b) (applicability provision for in-use off-road diesel-fueled fleets regulation).

      Second, we find that the submitted regulations would be sufficiently specific so that the persons affected by the regulations would be fairly on notice as to what the requirements and related compliance dates area. For instance, see the performance requirements for in-use off-road diesel-fueled fleets in 13 CCR section 2449(d). Third, none of the submitted regulations contain sunset provisions that automatically repeal the emissions limits by a given date or upon the occurrence of a particular event, such as the change in the designation of an area from nonattainment to attainment.\7\

      ---------------------------------------------------------------------------

      \7\ The only such provisions in any of the submitted regulations are a sunset provision for alternative requirements in the ZEV regulations at 13 CCR section 1962.1(b)(2)(B)(3.), and a sunset review of the on-road motorcycle standards at 13 CCR section 1958(h). The latter provision requires CARB to review the on-road motorcycle standards in section 1958 to determine whether they should be retained, revised, or repealed. Any such revision or rescission would not be become effective automatically, but would require rulemaking by CARB, and may also require a waiver from the EPA depending on the nature or the revision.

      ---------------------------------------------------------------------------

      Fourth, a number of the submitted regulations contain provisions that allow for discretion on the part of CARB's Executive Officer. Such ``director's discretion'' provisions can undermine enforceability of a SIP regulation, and thus prevent full approval by the EPA. However, in the instances of ``director's discretion'' in the submitted regulations, the discretion that can be exercised by the CARB Executive Officer is reasonably limited under the terms of the regulations. For instance, the regulation establishing standards and other requirements related to the control of emissions from commercial harbor craft includes alternative control of emissions (ACE) provisions that allow a person to be deemed in compliance by implementing an alternative emission control strategy (AECS) subject to the approval of the Executive Officer. See 13 CCR section 93118.5(f). The regulation specifies the application process for such an AECS, requires a number of demonstrations to be included (such as equivalent emissions reduction), and provides for public review. With such constraints on discretion, the ``director's discretion'' contained in the submitted regulations would not significantly undermine enforceability of the rules by citizens or the EPA.

      Lastly, each of the submitted regulations identifies appropriate test methods and includes adequate recordkeeping and reporting requirements sufficient to ensure compliance with the applicable requirements. The technical support document provides more detail concerning the contents of the submitted regulations.

      4. Do the regulations interfere with reasonable further progress and attainment or any other applicable requirement of the Act?

      All of the state's reasonable further progress (RFP), attainment, and maintenance plans rely to some extent on the emission reductions from CARB's mobile source program, including the emissions standards and other requirements for which the EPA has issued waivers or authorizations. For some plans, the reliance is substantial and for others the reliance is less. CARB's mobile source program is reflected in the emissions estimates for mobile sources that are included in the emissions inventories that form the quantitative basis for the RFP, attainment, and maintenance demonstrations. As such, CARB's mobile source regulations submitted for approval as a revision to the California SIP support the various RFP, attainment, and maintenance plans, and would not interfere with such requirements for the purposes of CAA section 110(l).

      As noted above, CARB expressly excluded certain sections or subsections of California code from consideration as part of the SIP revision. These provisions relate to GHG motor vehicle emissions standards and test procedures, fuel requirements, idling limits, opacity standards, daily mass emission limits, and certain labeling and consumer notification requirements. We understand that the GHG provisions have been excluded because they provide minimal emissions reductions over the time period covered by the current generation of California RFP, attainment, and maintenance plans. With respect to the non-preempted provisions, we understand that they were not included in the August 14, 2015 SIP submittal because they are not ``waiver measures'' and thus are not relevant for the purposes of responding to the Ninth Circuit's decision in Committee for a Better Arvin v. EPA. However, we note the general principle that state emissions limitations and other control measures that are relied upon to meet CAA SIP requirements, such as RFP, attainment or maintenance demonstrations, must be approved into the SIP to comply with the requirement for such limitations and other control measures to be enforceable for the purposes of CAA section 110(a)(2)(A). Thus, we encourage CARB to review the RFP, attainment, and maintenance plans for the various air quality planning areas in California to ensure that the plans do not rely on the associated emissions reductions from the provisions excluded from the August 14, 2015 SIP submittal.

      5. Will the state have adequate personnel and funding for the regulations?

      In its SIP revision submittal, CARB refers to the annual approval by the California Legislature of funding and staff resources for carrying out CAA-related responsibilities and notes that a large portion of CARB's budget has gone toward meeting CAA mandates.\8\ CARB indicates that a majority of CARB's funding comes from dedicated fees collected from regulated emission sources and other sources such as vehicle registration fees and vehicles license plate fees and that these funds can only be used for air pollution control activities. Id. For the 2014-2015 budget cycle, CARB had over 700 positions and almost $500 million dedicated for the mobile source program developing and enforcing regulations. Id. Given the longstanding nature of CARB's mobile source program, and its documented effectiveness at achieving significant reductions from mobile sources, we find that CARB has provided necessary assurances that the state has adequate personnel and funding to carry out the mobile source regulations submitted for approval as part of the California SIP.

      6. EPA's Evaluation Conclusion

      Based on the above discussion, we believe these regulations are consistent with the relevant CAA requirements, and with relevant EPA policies and guidance.

    3. Proposed Action and Request for Public Comment

      Under section 110(k)(3) of the CAA, and for the reasons given above, we are proposing to approve a SIP revision submitted by CARB on August 14, 2015 that includes certain sections of title 13 and title 17 of the California Code of Regulations that establish standards and other requirements relating to the control of emissions from new and in-use on-road and off-road vehicles and engines. We are proposing to approve these regulations as part of the California SIP because we believe they fulfill all relevant CAA requirements. We will accept comments from the public on this proposal until December 14, 2015. Unless we receive convincing new information during the comment period, we intend to publish a final approval action that will incorporate these rules into the federally enforceable SIP for the State of California.

  9. Incorporation by Reference

    In this proposed rule, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference certain sections of title 13 and title 17 of the California Code of Regulations that establish standards and other requirements relating to the control of emissions from new and in-use on-road and off-road vehicles and engines, as described in section II of this preamble. The EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the appropriate EPA office (see the ADDRESSES section of this preamble for more information).

  10. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this proposed action merely approves state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

    Is not a ``significant regulatory action'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

    Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

    Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);

    Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);

    Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

    Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

    Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

    Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and

    Does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

    In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, this proposed rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.
