IV. Incorporation by Reference V. Statutory and Executive Order Reviews I. 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 assignsThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 6

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.This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version.

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 programThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 8

(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 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 thatThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 9

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.

action today under CAA section 110(k) on CARB’s August 14, 2015

SIP revision submittal.

II. The State’s Submittal A. 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 forThis document is a prepublication version signed by EPA Regional

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.This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version.

21

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. B. 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 beThis document is a prepublication version signed by EPA Regional

22

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 website 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 notThis document is a prepublication version signed by EPA Regional

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. C. 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 PM 10 and PM 2.5 ) 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 (NO X ), sulfur dioxide (SO 2 ) and particulate matter (PM) in the various air quality planning areas within California, and thus, the purpose of CARB’s mobileThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version.

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. D. 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. TABLE 3: General Description of Requirements established in the Mobile Source Regulations included in the August 14, 2015 SIP Revision

Source Category Description of Requirements in Submitted Regulation On-Road PassengerCars, LightDuty Trucks,and MediumDuty Vehicles (LEV II) CARB’s “LEV II” regulations establish exhaust and

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

3 VOC and NO x are p r ecursors responsible for the formation of ozone, and NO X and SO 2 are precurs o rs for fine particulate matter (PM 2 .5 ). SO 2 belongs to a family of compounds referred to as sulfur oxides (SO X ). PM 2 .5 precursors also include VOC and ammonia. See 40 CFR 51.1000.This document is a prepublication version signed by EPA Regional

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 PassengerCars, LightDuty Trucks,and MediumDuty Vehicles ( LEV III) and Zero Emission Vehicles (ZEV) CARB’s LEV III and ZEV amendments combine the

control of criteria air pollutants and GHG emissions 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 withThis document is a prepublication version signed by EPA Regional

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 mot orcycle engines. For additional information about CARB’s motorcycle regulations, see 71 FR 44027 (August 3, 2006). On-Road Heavy-DutyEngines - OnBoard Diagnostic System (HD OBD) CARB’s HD OBD regulations 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 o f 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 or vehicle idle controls As submitted, CARB’s truck idling 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 Establishes in-use performance standards for

Transport Refrigeration Units (TRUs) 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, andThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 28

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). Off-RoadLarge SparkIgnition (LSI) Engines CARB’s LSI regulations establish 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-Going Vessels CARB’s “At-Berth” regulation 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 otherwiseThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 29

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 OffRoad 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 NO x standard, or to reduce emissions through technology upgrades such as retrofit orreplacement. For more information about CARB’s InUse 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 engine is used in off-road equipment or a vehicle registered as an on-road motor vehicle, and whether they are newly acquired or already in-use

. For more information about CARB’s mobile CHE regul ation, see 77 FR 9916 (February 21, 2012) and 80 FR 26249 (May 7, 2015).Small OffRoad Engines (SORE) CARB’s SORE regulations establish emissions

standards for new spark ignition utility and lawn and garden equipment engines 25 horsepower and under. For more information about CARB’s SORE regulations, see 80 FR 26041 (May 6, 2015).This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 30

Off-Road Compression – Ignition (CI) Engines CARB’s Off-Road CI Engine Regulations establish

emissions standards for new off-road dieselpowered engines and equipment. For more information about CARB’s Off-Road CI Engine Regulations, see 75 FR 8056 (February 23, 2010). In-Use Portable Diesel- Fueled Engines (PDE) CARB’s PDE regulation establishes requirements for

in-use portable diesel-fueled engines 50 brakehorsepower (hp) and greater. Specifically, starting on January 1, 2010, all portable engines in California must be certified to meet a federalor California standard for newly manufactured offroad 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 about CARB’s PDE regulation, see 77 FR 72846 (December 6, 2012). Portable Equipment Registration Program (PERP) PERP is a voluntary statewide 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, see 77 FR 72851 (December 6,This document is a prepublication version signed by EPA Regional

2012).SparkIgnition Inboard and Sterndrive Marine Engines CARB’s Inboard and Sterndrive Marine Engine

regulations establish tier II hydrocarbon (HC) and NO x exhaust emissions standards for new inboard and sterndrive engines. For more information about CARB’s Marine SI Engine regulations, see 72 FR 14546 (March 28, 2007) and 76 FR 24872 (May 3, 2011).SparkIgnition Marine Engines and Boats (Marine SI) CARB’s Marine SI Engine regulations establish HC

and NO x exhaust emissions standards for outboard, inboard, and sterndrive engines and personal watercraft. For more information about CARB’s Marine SI Engine regulations, see 72 FR 14546 (March 28, 2007), 76 FR 24872 (May 3, 2011), and 80 FR 26032 (May 6, 2015). Off-Highway Recreational Vehicles and Engines (OHRV) CARB’s OHRV regulations establish exhaust and

evaporative emission 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 about CARB’s OHRV regulations, see 79 FR 6584 (February 4, 2014).

III. EPA’s Evaluation and Proposed Action A. 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 asThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 32

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 B. 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

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.This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 33

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, 2015This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 34

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 adoptThis document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 35

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 motorvehicles) and 209(e)(2)(most categories of new and in-use offroad vehicles).This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 36

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. 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

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.This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 37

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 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). 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

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.This document is a prepublication version signed by EPA Regional

provision for off-road LSI engine emission standard regulation);13 CCR section 2449(b) (applicability provision for in-use offroad 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 dieselfueled 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 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

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.This document is a prepublication version signed by EPA Regional

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 theThis document is a prepublication version signed by EPA Regional

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 theThis document is a prepublication version signed by EPA Regional

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 notThis document is a prepublication version signed by EPA Regional

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. C. 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 [ INSERT

DATE 30 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER ]. Unless we receive convincing new information during the comment period, we intend to publish a final approval action that willThis document is a prepublication version signed by EPA Regional

incorporate these rules into the federally enforceable SIP for

the State of California. IV. 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). V. 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 roleThis document is a prepublication version signed by EPA Regional

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 (Public Law 104-4);

• does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);This document is a prepublication version signed by EPA Regional

Administrator Jared Blumenfeld on October 30, 2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. 46

• 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,This document is a prepublication version signed by EPA Regional
