[FRL-9768-1]
California State Motor Vehicle Pollution Control Standards; Notice of Decision Granting a Waiver of Clean Air Act Preemption for California's Advanced Clean Car Program and a Within the Scope Confirmation for California's Zero Emission Vehicle Amendments for 2017 and Earlier Model Years

SUMMARY:

The Environmental Protection Agency (EPA) is granting the California Air Resources Board's (CARB's) request for a waiver of Clean Air Act preemption to enforce its Advanced Clean Car (ACC) regulations. The ACC combines the control of smog and soot causing pollutants and greenhouse gas (GHG) emissions into a single coordinated package of requirements for passenger cars, light-duty trucks and medium-duty passenger vehicles (and limited requirements related to heavy-duty vehicles). The ACC program includes revisions to California's Low Emission Vehicle (LEV) program as well as its Zero Emission Vehicle (ZEV) program. By today's decision, EPA has also determined that CARB's amendments to the ZEV program as they affect 2017 and prior model years (MYs) are within the scope of previous waivers of preemption granted to California for its ZEV regulations. In the alternative, EPA's waiver of preemption for CARB's ACC regulations includes a waiver of preemption for CARB's ZEV amendments as they affect all MYs, including 2017 and prior MYs. In addition, EPA is including CARB's recently adopted “deemed to comply” rule for GHG emissions in today's waiver decision. This decision is issued under section 209(b) of the Clean Air Act (the “Act”), as amended.

DATES:

Petitions for review must be filed March 11, 2013.

I. Executive Summary

Today, as Assistant Administrator of the EPA's Office of Air and Radiation, I am granting California's request for a waiver of Clean Air Act preemption for California's ACC that combines the control of smog and soot causing pollutants and GHG emissions into a single coordinated package of requirements for MY 2015 through 2025 passenger cars (PCs), light-duty trucks (LDTs), medium-duty passenger vehicles (MDPVs), and limited requirements related to heavy-duty vehicles (HDVs). The ACC program regulations include revisions to both California's LEV and ZEV programs. By letter dated June 27, 2012, CARB submitted a request (CARB waiver request) that EPA grant a waiver of preemption under section 209(b) of the Clean Air Act (CAA), 42 U.S.C. 7543(b) for the revisions to the LEV program (LEV III).
1

CARB also sought confirmation that the amendments to the ZEV program are within the scope of prior waiver decisions issued by EPA, or in the alternative requested a waiver for these revisions (the LEV III and ZEV amendments, together known as the ACC, are considered as CARB's waiver request). By letter dated December 7, 2012, CARB submitted additional information (CARB supplemental request) to EPA requesting that EPA consider as part of CARB's pending ACC waiver request the CARB's Executive Officer adopted “deemed to comply” regulation.
2

CARB's “deemed to comply” regulation, adopted by CARB's Board on November 15, 2012 and final action taken by CARB's Executive Officer on December 6, 2012, allows automobile manufacturers to demonstrate compliance with CARB's GHG standards by complying with

EPA's GHG standards which were published for those MYs.

2
CARB supplemental request at EPA-HQ-OAR-2012-0562-0374.

By today's decision we are confirming that CARB's ZEV amendments, as they affect 2017 and prior MYs are within the scope of previous ZEV waivers. EPA also finds that the entire ACC program meets the criteria for a waiver of Clean Air Act preemption and thus we are granting a waiver for CARB's ACC program. Included in EPA's full waiver are CARB's “deemed to comply” regulations, and the ZEV regulations as they affect 2017 and prior MYs.

The legal framework for this decision stems from the waiver provision first adopted by Congress in 1967, and later modified in 1977. Congress established that there would be only two programs for control of emissions from new motor vehicles—EPA emission standards adopted under the Clean Air Act, and California emission standards adopted under state law. Congress accomplished this by preempting all state and local governments from adopting or enforcing emission standards for new motor vehicles, while at the same time providing that California could receive a waiver of preemption for its emission standards and enforcement procedures. Other states can only adopt standards that are identical to California's standards. This struck an important balance that protected manufacturers from multiple and different state emission standards, and preserved a pivotal role for California in the control of emissions from new motor vehicles. Congress recognized that California could serve as a pioneer and a laboratory for the nation in setting new motor vehicle emission standards. Congress intentionally structured this waiver provision to restrict and limit EPA's ability to deny a waiver. The provision was designed to ensure California's broad discretion to determine the best means to protect the health and welfare of its citizens.

Section 209(b) specifies that EPA must grant California a waiver if California determines that its standards are, in the aggregate, at least as protective of the public health and welfare as applicable federal standards. EPA may deny a waiver only if it makes at least one of three findings specified under the Clean Air Act (including whether California's “protectiveness finding” noted above is arbitrary and capricious). Therefore, EPA's role upon receiving a request for waiver of preemption from California is to determine whether it is appropriate to make any of the three findings specified by the Clean Air Act and if the Agency cannot make at least one of the three findings then the waiver must be granted. The three waiver criteria are properly seen as criteria for a denial—EPA must grant the waiver unless at least one of three criteria for a denial is met. This is different from most waiver situations before the Agency, where EPA typically determines whether it is appropriate to make certain findings necessary for granting a waiver, and if the findings are not made then a waiver is denied. This reversal of the normal statutory structure embodies and is consistent with the congressional intent of providing deference to California to maintain its own new motor vehicle emissions program.

The three criteria for denial of a waiver are: first, whether California's determination that its standards are, in the aggregate, at least as protective as applicable federal standards is arbitrary and capricious (Section 209(b)(1)(A)); second, whether California has a need for such standards to meet compelling and extraordinary conditions (Section 209(b)(1)(B)); and third, whether California's standards are consistent with Section 202(a) of the Clean Air Act (Section 209(b)(1)(C)). EPA and the Court of Appeals for the District of Columbia Circuit have consistently interpreted section 209(b) as placing the burden on the opponents of a waiver to demonstrate that one of the criteria for a denial has been met.

If California acts to amend a previously waived standard or accompanying enforcement procedure, the amendment may be considered within the scope of a previously granted waiver provided that it does not undermine California's determination that its standards in the aggregate are as protective of public health and welfare as applicable federal standards, does not affect its consistency with section 202(a) of the Clean Air Act, and raises no new issues affecting EPA's previous waiver decisions.

see also, e.g.,
46 FR 36742 (July 15, 1981).

In this case, California is combining three sets of motor vehicle emission standards into a single ACC waiver request. The standards are complimentary in the way they address interrelated ambient air quality needs and climate change. EPA has previously granted a series of waiver and within the scope decisions regarding CARB's LEV, ZEV and GHG emission programs.

EPA-HQ-OAR-2012-0562-0352.

After a thorough evaluation of the record, we have determined that the waiver opponents have not met their burden of proof in order for us to deny the CARB's waiver request under any of the three criteria in section 209(b)(1). EPA also confirms that CARB's ZEV amendments, as they affect the 2017 and earlier MYs are within the scope of previous waivers of preemption. In the alternative, EPA's waiver of preemption for CARB's ACC regulations includes a

waiver of preemption for CARB's ZEV amendments as they affect all MYs, including 2017 and prior MYs.

II. Background

A. California's Advanced Clean Car Program for New Motor Vehicles

As further explained below, CARB has adopted amendments to title 13, California Code of Regulations (CCR), and has established a single coordinated package that includes amendments to three sets of regulations regulating emissions from new PCs, LDTs, MDPVs, and certain HDVs:
9

the LEV regulation which includes two components—standards relating to criteria pollutants and standards to regulate GHG emissions, and the ZEV program.

9
Medium-duty vehicles (MDVs) are vehicles in California's regulations between 8,500 and 114,000 lbs GVWR that are also called Class 2b/Class 3 vehicles. These vehicles are generally termed Heavy-duty vehicles under EPA's regulations.

This single ACC program combines the control of smog-causing pollutants and GHG emissions into a coordinated package of amendments and requirements for MY 2015 through 2025 in order to address near and long term smog issues within California and identified GHG emission reduction goals. The program also includes amended ZEV regulations and a Clean Fuels Outlet regulation. These additional program elements are designed to address these goals as well.
10

The ACC program, together, provides the regulated manufacturers with the ability to plan and integrate their product designs in order to meet applicable CARB emission requirements.

10
CARB's Clean Fuel Outlet Regulation is not subject to preemption under section 209 of the Clean Air Act.

In order to achieve further emission reductions from the light- and medium-duty fleet, CARB adopted several amendments that represent a strengthening of its ongoing LEV regulations, including: a reduction of fleet average emissions of new PCs, LDTs, and MDPVs to super ultra-low-emission vehicle (SULEV) levels by 2025; replacement of separate non-methane organic gas (NMOG) and oxides of nitrogen (NO
X
) standards with combined NMOG plus NO
X
standards, which provides automobile manufacturers with additional flexibility in meeting the new stringent standards; an increase of full useful life durability requirements from 120,000 miles to 150,000 miles, which guarantees vehicles sustain these extremely low emission levels longer; a backstop to assure continued production of super-ultra-low-emission vehicles after partial-zero-emission vehicles (PZEVs) as a category are moved from the ZEV regulations to the LEV regulations in 2018; more stringent particulate matter (PM) standards for light- and medium-duty vehicles, which will reduce the health effects and premature deaths associated with these emissions; zero fuel evaporative emission standards for PCs and LDTs, and more stringent standards for medium- and heavy-duty vehicles (MDVs); and, more stringent supplemental federal test procedure (SFTP) standards for PC and LDTs, which reflect more aggressive real world driving and, for the first time, require MDVs to meet SFTP standards.

The second component of CARB's LEV III regulations includes amendments to its GHG emission standards. CARB's GHG standards for the 2017 through 2025 MYs are designed to respond to California's identified goals of reducing GHG emissions to 80 percent below 1990 levels by 2050 and in the near term to reduce GHG levels to 1990 levels by 2020. As such, CARB's GHG amendments: reduce new light-duty CO
2
emissions from new light-duty regulatory MY 2016 levels by approximately 34 percent by MY 2025, and from about 251 grams of CO
2
per mile to 166 grams, based on the projected mix of vehicles sold in California; set emission standards for CO
2
, CH
4
, and N
2
O; establish footprint based CO
2
emission standards, as distinguished from the current California GHG requirement of a fleet average GHG standard (this will allow manufacturers' new vehicle fleet CO
2
emissions to fluctuate according to their car-truck composition and sales according to vehicle footprint and will align the requirement with current federal GHG requirements); provide credits toward the CO
2
standard if a manufacturer reduces refrigerant emissions from the vehicle's air conditioning system; provide credits toward the ZEV standards if a manufacturer over complies with the LEV III GHG fleet requirement; provide credits towards the CO
2
standards if a manufacturer produces full size pickups with high efficiency drive trains; provide credits for deployment of technologies that reduce off-cycle CO
2
emissions; and require upstream emissions from zero-emission vehicles to be counted towards a manufacturer's light-duty vehicle GHG emissions. CARB's GHG emission regulations also include an optional compliance path whereby manufacturers may demonstrate compliance with CARB's GHG emission regulations by complying with applicable EPA GHG emission requirements.

Lastly, CARB's ACC regulations include amendments to its ZEV regulations that can be described within two timeframes: (1) MY 2012 through 2017; and (2) MY 2018 and beyond. CARB's stated goal for amendments to the current ZEV regulation through MY 2017 is to make corrections and clarifications to its regulations and to enable manufacturers to successfully meet the 2018 and later MY requirements. These amendments include: A provision of compliance flexibility whereby carry forward credit limitations for ZEVs were removed, allowing manufacturers to bank ZEV credits indefinitely for use in later years (the flexibility also included slightly reducing the 2015 through 2017 credit requirement for intermediate volume manufacturers (IVM, less than 60,000 vehicles produced each year), to allow them to better prepare for requirements in 2018, and included a provision that allows ZEVs placed in any state that has adopted the California ZEV regulation to count towards the ZEV requirement through 2017 (i.e. extending the “travel provision” for BEVs through 2017); an adjustment of credits and allowances; and an addition of a new vehicle category (collectively “BEVx” vehicles) as a compliance option for manufacturers to meet up to half of their minimum ZEV requirement.

CARB's stated goal for its amendments affecting 2018 and subsequent MYs is the commercialization of ZEVs and “transitional zero-emission vehicles (TZEV; commonly a plug-in hybrid electric vehicle—PHEV). California would achieve this objective by simplifying its regulation and pushing higher production volumes which in turn would achieve cost reductions. These amendments include: an increased ZEV requirement for 2018 and subsequent MYs that pushes ZEVs and TZEVs to more than 15 percent of new sales by 2025; the removal of PZEV (near-zero emitting conventional technologies) and advanced technology PZEV (AT PZEV, typically non-plug-in HEVs) credits as compliance options for manufacturers; an allowance for manufacturers to use banked PZEV and AT PZEV credits earned in 2017 and previous MYs, but discount the credits, and place a cap on usage in 2018 and subsequent MYs; amended manufacturer size definitions that bring all but the smallest manufacturers under the full ZEV requirements by MY 2018; a m
odified credit system that b
ases credits for ZEVs on range, with 50 mile

BEVs earning 1 credit each and 350 Mile FCVs earning 4 credits each (the range of credit reflects the utility of the vehicle (i.e. the zero emitting miles it may travel) and its expected timing for commercialization) along with a simplified and streamlined TZEV credits system; a modified “travel” provision that ends the travel provision for BEVs after MY 2017and extends the travel provision for FCVs; and provisions allowing manufacturers who systematically over comply with the LEV III GHG fleet standard to offset a portion of their ZEV requirement in 2018 through 2021 MYs only.

B. EPA's Consideration of CARB's Request

By letter dated June 27, 2012, CARB submitted a request (CARB waiver request) seeking a waiver of Section 209(a)'s prohibition for its ACC standards.
11

On August 31, 2012, a
Federal Register
notice (FR Notice) was published announcing an opportunity for hearing and comment on CARB's request.
12

EPA held a public hearing in Washington, DC on September 19, 2012. The written comment period closed on October 19, 2012.

11
EPA-HQ-OAR-2012-0562-0004.

12
77 FR 53199 (August 31, 2012).

EPA's FR Notice on CARB's waiver request asked for comment on several matters. Since CARB had submitted a within the scope request for its ZEV amendments as they affect both the 2012-2017 MYs and 2018 and subsequent MYs, EPA invited comment on the following issues: first, should California's ZEV amendments, as they affect the 2012-2017 MYs and/or the 2018 and later MYs, be considered under the within the scope criteria or should they be considered under the full waiver criteria?; second, to the extent part or all of those ZEV amendments should be considered as a within the scope request, do such amendments meet the criteria for EPA to confirm that they are within the scope of prior waivers? EPA also solicited comment in the event that EPA cannot confirm that some or all of CARB's ZEV amendments are within the scope of previous waivers. We also requested comment on all aspects of the full waiver analysis with regard to the ACC program (the LEV III criteria pollutant and GHG regulations, and the ZEV amendments to the extent EPA does not consider them under the within the scope analysis noted above). Therefore, we asked commenters to consider the following three criteria: whether (a) California's determination that its motor vehicle emission standards are, in the aggregate, at least as protective of public health and welfare as applicable Federal standards is arbitrary and capricious, (b) California needs such standards to meet compelling and extraordinary conditions, and (c) California's standards and accompanying enforcement procedures are consistent with section 202(a) of the Clean Air Act.

Because CARB noted (in its waiver request and in its incorporated Board Resolution 12-11) its commitment to propose a “deemed to comply” rule for its GHG standards shortly after EPA finalized its light-duty vehicle GHG emission standards, EPA specifically invited comment on CARB's waiver request in light of CARB's explicit plans concerning adoption of a “deemed to comply” provision into its LEV III GHG standards.

III. Analysis of Preemption Under Section 209 of the Clean Air Act

A. Clean Air Act Preemption Provisions

Section 209(a) of the Act provides:

No State or any political subdivision thereof shall adopt or attempt to enforce any standard relating to the control of emissions from new motor vehicles or new motor vehicle engines subject to this part. No State shall require certification, inspection or any other approval relating to the control of emissions from any new motor vehicle or new motor vehicle engine as condition precedent to the initial retail sale, titling (if any), or registration of such motor vehicle, motor vehicle engine, or equipment.
13

13
Clean Air Act (CAA) section 209(a), 42 U.S.C. § 7543(a).

Section 209(b)(1) of the Clean Air Act requires the Administrator, after an opportunity for public hearing, to waive application of the prohibitions of section 209(a) for any State that has adopted standards (other than crankcase emission standards) for the control of emissions from new motor vehicles or new motor engines prior to March 30, 1966, if the State determines that its State standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards.
14

However, no such waiver shall be granted by the Administrator if she finds that: (A) The protectiveness determination of the State is arbitrary and capricious; (B) the State does not need such State standards to meet compelling and extraordinary conditions; or (C) such State standards and accompanying enforcement procedures are not consistent with section 202(a) of the Act. In previous waiver decisions, EPA has stated that Congress intended EPA's review of California's decision-making be narrow. This has led EPA to reject arguments that are not specified in the statute as grounds for denying a waiver:

14
CAA section 209(b), 42 U.S.C. § 7543(b). California is the only State which meets section 209(b)(1)'s requirement for obtaining a waiver.
See
S. Rep. No. 90-403 at 632 (1967).

The law makes it clear that the waiver requests cannot be denied unless the specific findings designated in the statute can properly be made. The issue of whether a proposed California requirement is likely to result in only marginal improvement in air quality not commensurate with its cost or is otherwise an arguably unwise exercise of regulatory power is not legally pertinent to my decision under section 209, so long as the California requirement is consistent with section 202(a) and is more stringent than applicable Federal requirements in the sense that it may result in some further reduction in air pollution in California.
15

15
36 FR 17458 (Aug. 31, 1971). Note that the more stringent standard expressed here, in 1971, was superseded by the 1977 amendments to section 209, which established that California must determine that its standards are, in the aggregate, at least as protective of public health and welfare as applicable Federal standards.

Thus, my consideration of all the evidence submitted concerning a waiver decision is circumscribed by its relevance to those questions that I may consider under section 209(b).

B. Deference to California

In previous waiver decisions, EPA has recognized that the intent of Congress in creating a limited review based on the section 209(b)(1) criteria was to ensure that the federal government did not second-guess state policy choices. This has led EPA to state:

It is worth noting * * * I would feel constrained to approve a California approach to the problem which I might also feel unable to adopt at the federal level in my own capacity as a regulator. The whole approach of the Clean Air Act is to force the development of new types of emission control technology where that is needed by compelling the industry to “catch up” to some degree with newly promulgated standards. Such an approach * * * may be attended with costs, in the shaped of reduced product offering, or price or fuel economy penalties, and by risks that a wider number of vehicle classes may not be able to complete their development work in time. Since a balancing of these risks and costs against the potential benefits from reduced emissions is a central policy decision for any regulatory agency under the statutory scheme outlined above, I believe I am required to give very substantial deference to California's judgments on this score.
16

16
40 FR 23103-23104;
see also
LEV I (58 FR 4166), January 13, 1993)Decision Document at 64.

EPA has stated that the text, structure, and history of the California waiver provision clearly indicate both a congressional intent and appropriate EPA practice of leaving the decision on “ambiguous and controversial matters of

public policy” to California's judgment.
17

17
40 FR 23104; 58 FR 4166.

The House Committee Report explained as part of the 1977 amendments to the Clean Air Act, where Congress had the opportunity to restrict the waiver provision, it elected instead to explain California's flexibility to adopt a complete program of motor vehicle emission controls. The amendment is intended to ratify and strengthen the California waiver provision and to affirm the underlying intent of that provision, i.e., to afford California the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare.

627 F.2d at 1122.

The court in
MEMA I
considered the standards of proof under section 209 for the two findings necessary to grant a waiver for an “accompanying enforcement procedure” (as opposed to the standards themselves): (1) Protectiveness in the aggregate and (2) consistency with section 202(a) findings. The court instructed that “the standard of proof must take account of the nature of the risk of error involved in any given decision, and it therefore varies with the finding involved. We need not decide how this standard operates in every waiver decision.”

Id.

The court upheld the Administrator's position that, to deny a waiver, there must be `clear and compelling evidence' to show that proposed procedures undermine the protectiveness of California's standards.
21

The court noted that this standard of proof also accords with the congressional intent to provide California with the broadest possible discretion in setting regulations it finds protective of the public health and welfare.
22

Id.

With respect to the consistency finding, the court did not articulate a standard of proof applicable to all proceedings, but found that the opponents of the waiver were unable to meet their burden of proof even if the standard were a mere preponderance of the evidence. As we explained in the GHG waiver decision, although
MEMA I
did not explicitly consider the standards of proof under section 209 concerning a waiver request for “standards,” as compared to accompanying enforcement procedures, there is nothing in the opinion to suggest that the court's analysis would not apply with equal force to such determinations.
23

EPA's past waiver decisions have consistently made clear that: “[E]ven in the two areas concededly reserved for Federal judgment by this legislation—the existence of compelling and extraordinary' conditions and whether the standards are technologically feasible—Congress intended that the standards of EPA review of the State decision to be a narrow one.”

74 FR 32748

24

See, e.g.,
40 FR 21102-103 (May 28, 1975).

Finally, opponents of the waiver bear the burden of showing that the criteria for a denial of California's waiver request has been met. As found in
MEMA I,
this obligation rests firmly with opponents of the waiver in a section 209 proceeding, holding that: “[t]he language of the statute and it's legislative history indicate that California's regulations, and California's determinations that they must comply with the statute, when presented to the Administrator are presumed to satisfy the waiver requirements and that the burden of proving otherwise is on whoever attacks them. California must present its regulations and findings at the hearing and thereafter the parties opposing the waiver request bear the burden of persuading the Administrator that the waiver request should be denied.”

MEMA I,
627 F.2d at 1121.

The Administrator's burden, on the other hand, is to make a reasonable evaluation of the information in the record in coming to the waiver decision. As the court in
MEMA I
stated, Ahere, too, if the Administrator ignores evidence demonstrating that the waiver should not be granted, or if he seeks to overcome that evidence with unsupported assumptions of his own, he runs the risk of having his waiver decision set aside as `arbitrary and capricious.”
26

Therefore, the Administrator's burden is to act “reasonably.”

D. Comments Received on EPA's Application of the Section 209(b) Criteria

The Dealers provided a series of suggestions on several threshold issues for how EPA should evaluate CARB's ACC waiver request. While the ACC regulatory components are interrelated, the Dealers state that EPA should evaluate them separately by applying each of the three waiver criteria under section 209(b).
28

NADA does not address the application of the three waiver criteria to CARB's LEV III criteria pollutant regulations .

This commenter also suggests that it is CARB's burden to make a determination that its standards are at least as protective of the public health and welfare as any applicable federal standards, and to determine that the standards are technologically feasible.
29

This commenter also suggests that Congress allowed for a limited waiver only if California is able to show that its standards are necessary to address “the unique problems facing [the state] as a result of its climate and topography.”

Id.

In addition, the Dealers suggest that a decision to deny a CARB waiver request only need meet a “preponderance of the evidence” standard. This commenter maintains that such a standard would preserve the traditional presumption in favor of CARB's protectiveness determination while affording EPA or those opposed to the waiver the ability to uphold section 209's general preemption. The commenter suggests that EPA mischaracterizes the
MEMA
decision within its prior GHG waiver decision when EPA stated “there is nothing in the opinion to suggest that the court's analysis would not apply with equal force to such determinations.”
31

The commenter states that because the Court opined that the “preponderance of the evidence standard governs the inquiry into technological feasibility,” and the Court determined that the appropriate standard of proof “must take into account the nature of risk of error involved in any given decision” it is therefore appropriate that EPA must use its discretion to determine the appropriate standard when evaluating a waiver request under each element of

Section 209(b). To settle the question of the appropriate burden of proof the commenter cites
International Harvester
v.
Ruckelshaus
wherein the decision over burden of proof is informed by an analysis that balances the cost of a wrong decision on feasibility against the gains of a correct one: “These costs include the risk of grave maladjustments * * * and the impact on jobs and the economy from a decision which is only partially accurate * * * against the environmental savings.”

31
74 FR 32748. EPA notes that the language following this statement, in the same paragraph of the GHG waiver decision, states “EPA's past waiver decisions have consistently made clear that: “[E]ven in the two area concededly reserved for Federal judgment by this legislation—the existence of compelling and extraordinary conditions and whether the standards are technologically feasible—Congress intended that the standards of EPA review of the State decision to be a narrow one.”

With regard to the Dealers' first suggestion that EPA should separately apply the waiver criteria to each of the ACC regulatory components (
e.g.,
GHG emission standards and ZEV), EPA notes that each part of CARB's regulations are subject to EPA waiver review. As such, by today's decision we address any adverse comments in that regard. However (and as explained in further detail under EPA's analysis of each waiver criteria below), we believe the Dealers fundamentally misunderstand the specific language of the section 209(b), its congressional history, and EPA's past administrative waiver practice. For example, although EPA would typically examine whether CARB's regulation of each pollutant is as stringent as any applicable federal standard, we nevertheless recognize both the statutory language and legislative history that requires EPA to consider the protectiveness of a CARB standard “in the aggregate” of all emission standards covering that particular industry category (
e.g.,
light-duty vehicles, etc). Furthermore, under the second waiver criterion of section 209(b), EPA continues to evaluate whether those opposed to a waiver have demonstrated that CARB no longer experiences compelling and extraordinary conditions. As such, for any standard or set of standards presented to EPA for waiver consideration, EPA's evaluation continues to be whether CARB has a need for its motor vehicle emission program to address the underlying compelling and extraordinary conditions. This is further explained in our discussion of this waiver criterion. Similarly, although the Dealers might suggest that EPA only be obligated to determine whether each of CARB's ACC regulatory components, in isolation, is consistent with section 202(a) we believe the better approach is to determine the technological feasibility of each standard in the context of the entire regulatory program for the particular industry category. In this case, we believe CARB has in fact recognized the interrelated, integrated approach the industry must take in order to address the regulatory components of the ACC program. As noted above, the House Committee Report explained as part of the 1977 amendments to the Clean Air Act that California was to be afforded flexibility to adopt a
complete
program of motor vehicle emission controls (emphasis added). As such, EPA believes that Congress intended EPA to afford California the broadest possible discretion in selecting the best means to protect the health of its citizens and the public welfare.
32

EPA believes this intent extends to CARB's flexibility in designing its motor vehicle emission program and evaluating the aggregate effect of regulations within the program.

32
H.R. Rep No. 294, 95 Cong., 1st sess. 301-02 (1977).

With regard to CARB's initial burden in submitting a waiver request to EPA, we believe this commenter misreads both section 209(b) along with the case law and legislative history it cites. California is only required to make a protectiveness finding as a threshold matter before submitting its waiver request to EPA. Section 209(b) of the Clean Air Act plainly states that “The Administrator shall, * * *, waive application of this section* * *., if the State determines that the State standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. No such waiver shall be granted if the Administrator finds that * * *.” Nothing on the face of section 209(b) requires California to make affirmative findings or showings under section 209(b)(1)(B) or (C). The
MEMA I
decision cited to by the commenter does not support the suggestion that CARB must initially make an affirmative determination or showing beyond the protectiveness determination. Of course, whether or not CARB has such a burden, CARB has clearly provided in its initial waiver request considerable support for its view that its waiver request meets the requirements of section 209(b)(1)(B) and (C).

CARB waiver request and supporting attachments.

EPA continues to believe that the burden of proof for each waiver criteria lies on the opposing party. As earlier explained, this is inherent in the statutory provision that requires EPA to grant a waiver unless it makes one of the specific negative findings listed in section 209(b)(1).

The language of the statute and its legislative history indicate that California's regulations, and California's determination that they comply with the statute, when presented to the Administrator are presumed to satisfy the waiver requirements and that the burden of proving otherwise is on whoever attacks them. California must present its regulations and findings at the hearing, and thereafter the parties opposing the waiver request bear the burden of persuading the Administrator that the waiver request should be denied.
34

MEMA I,
627 F.2d at 1121.

Further, pertinent legislative history evinces Congressional intent to place the burden of proof on the party opposing a waiver. This appears most dramatically from the debates on the floor of the House over two alternative versions of the statutory language. One, sponsored by the relevant legislative committee, would have permitted the federal government, upon application showing by California, to set special California standards if certain conditions were met. The second, which was sponsored by the entire California delegation, see 113 Cong. Rec. H 14428 (Cong. Moss) (daily ed. Nov. 2, 1967), and eventually adopted on the floor, would have required the federal government to waive preemption of standards promulgated by California unless certain findings were made. Despite the understandable efforts of some sponsors of the committee language to portray the differences between the two versions as purely verbal the majority of the House clearly disagreed. 113 Cong. Rec. H 14404 (Cong. Herlong); H 14432 (Cong. Rogers) (daily ed. Nov. 2, 1967). Sponsors of the language eventually adopted (the language sponsored by the California delegation) referred repeatedly to their intent to make sure that no “Federal bureaucrat” would be able to tell the people of California what auto emission standards were good for them, as long as they were stricter than Federal standards. 113 Cong. Rec. H 14393 (Cong. Sess); H 14395 (Cong. Smith); H 14396 (Cong. Holffield); H 14399 (Cong. Hosmer); H 14408 (Cong. Roybal); H 14409 (Cong. Reinicke); H 14429 (Cong. Wlson) (daily ed. Nov. 2, 1967). Thus, at the close of the debate, the House rejected language that would have imposed the burden of proof on California and instead accepted language that which places the burden on those who allege, in effect, that EPA's GHG emission standards are adequate to California's needs. They also viewed the change as necessary to their intent to preserve the California state auto emission control program in its original form, see HR. Rep. No. 728, 90th Cong. 1st Se. 96-97 (1967) (separate views of Congressmen Moss and Van Deerlin), 113 Cong. Rec. H 14415 (daily ed. Nov. 2, 1967) (Cong.

Van Deerlin) and to continuing the national benefits that might flow from allowing California to continue to act as a pioneer in this field. 113 Cong. Rec. H 14407 (Cong. Moss) (daily ed. Nov. 2, 1967); S 16395 (daily ed. Nov. 14, 1967) (Senator Murphy). These points had also previously been made by the Senate Public Works Committee in reporting out waiver language identical to that eventually adopted by the House. S. Rep. No. 403, 90th Cong. 1st Sess. 32-33 (1967).

As also explained in
MEMA I:

Legislative history makes clear that the burden of proof lies with the parties favoring denial of the waiver. Petitioners lost the battle they now wage twelve years ago when Congress specifically declined to adopt a provision which would have imposed on California the burden to demonstrate that it met the waiver requirements. As noted, the Senate version of the Air Quality Act of 1967 contained the language which was ultimately adopted by Congress. It vested the power to make the protectiveness determination in California and sharply restricted the Secretary's role in a waiver proceeding. The Senate Report explained that under the proposal the “Secretary is required to waive application unless he finds” one of the factual circumstances set out in section 209(b)(1)(A)-(C). S. Rep. No. 403, 90th Cong., 1st Sess. 33 (1967).

Finally, with regard to the Dealers' arguments about the burden of proof, we believe it necessary to differentiate between two separate questions: 1) who has the burden of proof; and 2) what is the appropriate level of proof? A discussion of who holds the burden of proof is addressed above. Below is a discussion regarding the appropriate “level” of proof. EPA agrees with the Dealers that EPA has the discretion to determine the appropriate level of proof, and we are guided by the language of the statute, relevant case law, and our prior administrative practice.

With regard to the standard of proof applicable to CARB's protectiveness determination, EPA rejects any contention that the standard should be anything other than “clear and compelling evidence.” The language of section 209(b)(1)(A) requires that the Administrator find that CARB's protectiveness determination is “arbitrary and capricious” suggesting that EPA or others that may oppose the waiver must demonstrate that CARB's factual findings lacked any acceptable reasoning. As noted above, the
MEMA I
court upheld the Administrator's position that, to deny a waiver, there must be `clear and compelling evidence' to show that proposed procedures undermine the protectiveness of California's standards.
35

The court noted that this standard of proof also accords with the congressional intent to provide California with the broadest possible discretion in setting regulations it finds protective of the public health and welfare.
36

EPA believes there is no reason to jettison the precedent along with its past administrative waiver practice merely because CARB seeks a waiver for “standards” as opposed to “accompanying enforcement procedures.”

36

Id.

With respect to the second and third waiver criteria of section 209(b); however, EPA is also guided by the principles of deference noted above and by case law, as explained below in EPA's examination of technological feasibility. As the commenter notes, in the GHG waiver EPA reasoned that
MEMA I'
s holding on the applicable standard of proof should be extended to waiver of standards. EPA continues to believe that it is appropriate to impose a standard of preponderance of evidence on the proponent of denial of a waiver of standards, for the second and third waiver criteria. This standard would also be similar to the standard in civil matters. “This view of the standard of proof dictates the standard normally adopted in civil matters, a preponderance of the evidence.”
37

EPA also believes that it should apply such a standard in a way that accords with congressional intent to provide California with the broadest possible discretion in setting regulations that it finds protective of the public health and welfare
38

while limiting EPA's review to a narrow role that provides substantial deference to the State.

Further, EPA agrees with the commenter that in making its determination, EPA should be mindful of the risk of error involved.
40

But this does not change the burden of proof. “The Administrator is not entitled to ignore the evidence adduced at the hearing. He must consider all evidence that passes the threshold test of materiality and he must thereafter assess such material evidence against a standard of proof to determine whether the parties favoring a denial of the waiver have shown that the factual circumstances exist in which Congress intended denial of the waiver.”

In sum, based on the statutory structure of section 209(b)(1) and legislative history, the burden of proof falls on those who wish EPA to deny the waiver.

IV. California's Within the Scope Request for its Zero Emission Vehicle Amendments

CARB's waiver request sought confirmation from EPA that the ZEV amendments (2012 ZEV Amendments), as they relate to 2017 and prior MYs are within the scope of existing waivers. The ACC waiver request also sought confirmation that the 2012 ZEV amendments as they relate to 2018 and later MYs are within the scope of existing waivers, or, in the alternative, meets the criteria for a full waiver.

A. Chronology

California's initial ZEV program was included as part of its first low-emission vehicle program known as LEV I. The ZEV component of this program had a ZEV sales requirement starting with the 1998 MY and phasing in to a 10 percent sales requirement by the 2003 MY. EPA issued a waiver of preemption for these regulations on January 13, 1993.
42

CARB subsequently amended the ZEV regulations in March, 1996, by eliminating the ZEV sales requirement for the 1998-2002 MYs and retaining the 10 percent sales requirement for the 2003 and later MYs. EPA issued a within the scope determination for these amendments on January 5, 2001.
43

CARB again amended the ZEV regulations in 1999, 2001, and 2003 and on December 21, 2006, EPA waived preemption for these amendments through the 2011 MY.
44

The 2006 EPA action included a within the scope decision for certain components of the regulations and a full waiver authorization for other components. Specifically, EPA determined that certain provisions of the 1999-2003 amendments to the ZEV regulations affecting 2006 and prior MYs were within the scope of previous waivers of preemption. EPA's 2006 decision concurrently granted California's request for a waiver of preemption to enforce certain provisions of the ZEV regulations as they affected 2007 through 2011 MY vehicles. EPA also stated that that although we believed it appropriate to grant a full waiver of preemption for the 2007 MY, we also believed it appropriate to consider the 2007 MY regulations (with one exception noted) as within the scope of previous waivers of preemption, as they applied to certain vehicles that were

already subject to the pre-existing ZEV regulations. The 2006 waiver decision did not make any findings or determinations with regard to CARB's ZEV regulations as they pertained to the 2012 and later MYs. On October 3, 2011, EPA determined that additional CARB amendments to the ZEV regulations, as they affected 2011 and prior MYs, were within the scope of previous waivers for the ZEV regulations (or in the alternative qualified for a new waiver). At that time EPA also granted a waiver allowing California to enforce the ZEV amendments as they affected 2012 and later MYs.

B. CARB's ZEV Amendments

CARB's stated goal for the 2012 ZEV amendments, as they affect the ZEV regulation through MY 2017, was to make minor corrections and clarifications and to enable manufacturers to successfully meet the 2018 and later MY ZEV requirements. As such, the 2012 ZEV amendments included compliance flexibility provisions, adjustment of credits and allowances, and the addition of a new vehicle category that can earn credits to help manufacturers satisfy their sales requirement.

The compliance flexibility provisions include several modifications to the ZEV program credit and travel provisions. The limitations on carry forward credits for ZEVs are removed, allowing for indefinite banking of ZEV credits. The travel provision for credits from ZEV sales in Section 177 states is extended through 2017. Travel provision credits limit the credits manufacturers need to generate to those necessary for California, no matter how many states adopt the ZEV program under Section 177. Vehicles sold in section 177 states generate credits for California and vice versa under the travel provisions. The travel provision amendments allow for the continued travel of ZEV credits through MY 2017. Carry forward credits for ZEVs were previously limited to two additional model years. This limitation is removed by the 2012 amendments, allowing manufacturers to bank credits for all future model years. This modification is a flexibility to enable automakers to comply with the 2018 and later provisions.

In addition, the 2012 ZEV amendments provide for an adjustment of credits and allowances to incentivize longer-term technology. For example, the credits for Type V ZEVs (fuel cell vehicles with range of 300 miles or greater) are increased. Finally, the 2012 ZEV amendments create the addition of a new vehicle category that includes two new near-ZEV vehicle types: Type I.5x and Type IIx. These vehicles are plug-in hybrid electric vehicles (PHEVs) with more capable electric drive systems, but smaller engines that are not expected to be used often and have diminished performance. These vehicles can be used to meet up to one half of a manufacturer's minimum ZEV credit requirement. These vehicles will be eligible for the same credits as current Type I.5 (2.5 credits) and Type II (3 credits) and will qualify for travel provision credits through 2017.

Separately, CARB's stated goal for its 2012 ZEV amendments, as they affect 2018 and later MYs, is to achieve the commercialization of ZEVs and near-ZEVs such as PHEVs (with sales of approximately 15 percent of the new car market in California by 2025) by simplifying the regulation and pushing technology to higher volume production in order to achieve cost reductions. The amendments cover six major areas: increased ZEV requirements phased-in through 2025; the removal of “commercialized” technology from the ZEV program; amended manufacturer size definitions, ownership requirements and transitions; a modified credit system, a modified travel provision; and a new opportunity for manufacturers to generate additional ZEV credits via over compliance with applicable GHG emission standards during this time period.

The increased ZEV credit requirements are equivalent to approximately 15 percent ZEV and near-ZEV sales by 2025. This sales level is deemed by CARB to be the threshold at which costs will decrease due to volume effects. The credit requirement is being ramped up from the current program's static level of 16 percent total, which includes PZEVs and AT PZEVs. The new requirement consists of a 2 percent minimum ZEV and 2.5 percent minimum TZEV (4.5 percent total) requirement, ramping up to 16 percent minimum ZEV and 6 percent minimum TZEV (22 percent total) requirement in 2025 and beyond. The 2012 ZEV amendment revisions to credit calculations for ZEVs and TZEVs result in a projected market share of 15.4 percent of new sales in 2025.

Under the previous ZEV mandate, credits were allowed for PZEV-certified vehicles and HEVs which are not plugged in. CARB is removing these vehicle types from the credit scheme in MY 2018 and later. Remaining credits that are banked can continue to be used, but with discounts and caps applied.

Manufacturer size definitions have been amended to apply full ZEV mandate to all but the smallest manufacturers. Manufacturer sales volumes will be combined if joint ownership exceeds 33.4 percent and the transition period for manufacturers changing size categories has been modified. Under this system, 97 percent of the light-duty market will be covered by the ZEV mandate.

Currently, manufacturers with sales volumes exceeding 60,000 units in California are classified as large volume manufacturers (LVM). This modification reduces the threshold to 20,000 units, which will bring most manufacturers under the full ZEV mandate. This modification is being made because many of these current intermediate vehicle manufactures (IVMs) have a large market presence outside California. Remaining IVMs will be allowed to comply with the ZEV mandate with no restrictions on ZEV technology type, meaning an IVM can fully comply with TZEVs, but not PZEVs or AT PZEVs.

Additionally, ownership thresholds for treatment of automakers as one entity are being modified to more closely align them with GHG fleet regulations and changes are being made to the lead time provisions as manufacturers move between size classes.

CARB also modified its credit system. ZEV credits are based on range and technology reflecting utility of the vehicle and expected timing for commercialization. BEVs with a 50-mile range earn one credit and FCVs with 350 miles of range earn four credits each. Up to half a manufacturer's credit requirement may be met with more capable PHEVs which are meant to operate mainly as EVs, but are equipped with a small range-extending engine.

TZEVs, which are essentially PHEVs of the type available today such as the Chevrolet Volt have simplified credits based on electric range and a minimum requirement of 10 miles all-electric on the US06 test cycle. The TZEV credit ranges from a minimum of 0.2 to a maximum of 1.3 with a greater than 80 mile range.

Excess credits earned and banked from PZEVs and AT PZEVs will be discounted in 2018 and later years. Their use will then be limited to 25 percent of a manufacturer's TZEV requirement. No portion of the ZEV requirement may be met with banked credits. Smaller manufacturers (IVMs) will not have their credits capped for 2018 or 2019. In 2020 and later, the IVM cap will be 25 percent, but applied to their combined ZEV/TZEV requirement.

CARB has also modified the credit levels for various ZEV types. The current tiered CARB system, which encouraged manufacturers to design vehicles to meet a given range threshold is replaced with an equation that calculates credits based on the UDDS electric driving range.

In addition, CARB has modified its “travel provisions.” The travel provision, which allows for the sale of a qualifying vehicle in a Section 177 state to count towards a manufacturer's credit requirement in California, ends for BEVs after 2017. Since FCVs are far behind BEVs in development and market penetration, travel credits are extended for FCVs. California intends to extend travel credits until sufficient refueling infrastructure exists to support FCVs in the market.

Lastly, the 2012 ZEV amendments provide that automakers who over comply with the LEVIII GHG standard may use the extra GHG reductions to offset a portion of their ZEV requirement in MYs 2018 through 2021. Manufacturers may offset 50 percent of their ZEV mandate in 2018, ramping down to 30 percent in 2021, subject to certain requirements.

C. EPA's Determination Regarding the Appropriateness of CARB's Within the Scope Request for the 2012 ZEV Amendments

CARB primarily relies upon EPA's prior waiver and within the scope findings to demonstrate the appropriateness of applying the within the scope criteria to its 2012 ZEV amendments. In EPA's 2006 waiver determination, EPA stated that it will conduct a two-part inquiry when considering whether CARB amendments to a previously waived regulation fall within the scope of the previously granted waiver or whether the amendments require a new waiver:

EPA believes it is important to distinguish between the threshold issue of whether CARB's amendments should be subjected to either the within-the-scope criteria or the full waiver, and separately determining whether the same amendments actually meet the applicable criteria for actually confirming the within-the-scope request or granting a full waiver of federal preemption.

In determining the threshold question, EPA will consider whether the amendments make minor technical revisions or provide compliance flexibility on the one hand or whether the amendments add new or more stringent pollutant standards or new motor vehicle categories on the other.
46

46
Decision Document accompanying waiver determination in 71 FR 78190 (December 28, 2006).

With regard to the 2017 and earlier MYs, following the precedent noted above, CARB maintains that the 2012 ZEV amendments create no new issues affecting the previous waiver determinations concerning the ZEV program and that the 2012 ZEV amendments do not undermine CARB's original protectiveness determination and the ZEV regulations remain consistent with section 202(a). With regard to the 2018 and later MYs, CARB maintains that the within the scope criteria are appropriate since the overall ZEV credit requirement for MYs 2018 through 2022 is less burdensome than the currently waived program.

EPA received comment from the Manufacturers stating agreement that the amendments to the MYs 2009 through 2017 ZEV regulations qualify for a within the scope determination since the amendments increase the flexibility available to manufacturers to comply with those standards and otherwise lessen the burdens placed on manufacturers. However, the Manufacturers did not agree that the amendments to the ZEV regulation for 2018 and later MYs properly fall under the within the scope review. The commenter notes that in addition to the increase in the minimum ZEV credit requirements in 2018 MY and beyond, the CARB amendments also eliminate certain vehicle types (e.g., PZEVs and AT PZEVs) that were previously accepted towards compliance with the ZEV requirements during this time period. In addition, the Manufacturer notes that the changes to CARB's travel provisions are significant and raise serious compliance concerns.

The Dealers commented generally that the ZEV waiver should be denied, but raised no specific concerns about a within-the-scope determination for MYs 2012-2017.

Therefore, EPA has received no explicit comment suggesting that EPA reject CARB's request for confirmation that EPA evaluate the 2012 ZEV amendments as they affect the 2017 MY and earlier. EPA believes that it is appropriate to evaluate such amendments (which provide compliance flexibilities) under the within the scope criteria and applies such criteria below. However, with respect to the 2018 and later MYs, EPA agrees with the commenters that CARB's 2012 ZEV amendments have, in total, added to the level of stringency and compliance obligations. Therefore, EPA does not believe it is appropriate to apply within the scope analysis to the ZEV amendments as they apply in the 2018 and later MYs. As explained below, because EPA is applying the full waiver criteria for the 2012 ZEV amendments as they pertain to the 2018 and later MYS, EPA will in the alternative also examine the revisions for the 2017 and earlier MYs using the full waiver criteria.

D. Application of the Within the Scope Waiver Criteria to CARB's 2012 ZEV Amendments Regarding 2017 and Earlier MYs

1. Public Health and Welfare

Under section 209(b)(1)(A) of the Act, EPA cannot grant a waiver if the Agency finds that CARB was arbitrary and capricious in its determination that its State standards are, in the aggregate, at least as protective of public health and welfare as applicable federal standards. Similarly, under the criteria for a within the scope determination, the CARB amendments to an existing program may be considered within-the-scope of a previously granted waiver provided that the amendments do not undermine California's determination that its standards in the aggregate are as protective of public health and welfare as applicable Federal standards. Thus, in the within the scope context CARB may rely on the “protectiveness determination” that the Board made at the time of the initial regulations (the regulations which subsequently received a waiver of federal preemption from EPA) and then CARB must only demonstrate why the protectiveness determination has not been undermined by CARB's amendments or any other intervening events such as the adoption of EPA regulations since the initial waiver of federal preemption.

CARB asserts that its 2012 ZEV amendments as applied to MYs 2009 to 2017 are a critical component of the ACC package that will result in fleet standards that are at least as protective as would exist under federal standards. The Board resolved “that the Board hereby determines that the proposed regulations approved for adoption herein will not cause the California motor vehicle emission standards, in the aggregate, to be less protective of public health and welfare than applicable federal standards.”
47

CARB Resolution 12-11 at EPA-HQ-OAR-2012-0562-0005.

EPA received no comments suggesting that CARB's request should be denied on the basis of CARB failing to meet its burden associated with the protectiveness findings under section 209(b)(1)(A) of the Clean Air Act.

Therefore, based on the record before us, we cannot find that CARB's 2012 ZEV amendments, as the affect 2017 and earlier MYs, would undermine CARB's prior protectiveness determinations nor would it cause the California motor

vehicle emission standards, in the aggregate, to be less protective of public health and welfare than applicable federal standards.

2. Consistency With Section 202(a)

Under section 209(b)(1)(C), EPA cannot grant California its waiver request if the Agency finds that California standards and accompanying enforcement procedures are not consistent with section 202(a) of the Clean Air Act. Previous waivers of federal preemption have stated that California's standards are not consistent with section 202(a) if there is inadequate lead time to permit the development of technology necessary to meet those requirements, given appropriate consideration to the cost of compliance within that time. California's accompanying enforcement procedures would also be inconsistent with section 202(a) if the federal and California test procedures were inconsistent.

The scope of EPA's review of whether California's action is consistent with section 202(a) is narrow. EPA has previously found that the determination is limited to whether those opposed to the waiver have met their burden of establishing that California's standards are technologically infeasible, or that California's test procedures impose requirements inconsistent with the federal test procedure.
48

48

See MEMA I,
at 1126.

As previously noted, CARB maintains that the 2012 ZEV amendments, as they pertain to the 2017 and previous MYs, provide manufacturers with additional flexibility without increasing on balance the overall stringency of the preexisting ZEV requirements. EPA has received no comments explicitly questioning the feasibility of the amendments as they apply to these MYs. In the discussion below, EPA addresses the limited comments regarding the technological feasibility concerns with regard to 2018 and later MYs and EPA provides further analysis of the general technological feasibility concerns in the full waiver discussion. With regard to whether test procedures are consistent, CARB notes that the federal Tier 2 regulations require manufacturers to measure emissions from ZEVs in accordance with the California test procedures.
49

In addition, EPA has not received comment suggesting the test procedures are inconsistent. Therefore, based on the record before us, we cannot deny CARB's within the scope request for 2017 and prior MYs based on an inconsistency with section 202(a).

3. New Issues

As noted above, included in the within the scope criteria, is a determination of whether the amendments raise new issues affecting the previous waiver decisions. As previously noted, EPA examines any new information when reviewing whether CARB's amendments affect the ZEV program's consistency with section 202(a). If the amendments had increased the stringency of the standards upon the manufacturers (for the specific model years being reviewed in the within the scope analysis), or if the amendments had regulated or subjected new types of vehicles to be included in the ZEV program (or in this instance regulated the same vehicle types but for model years not previously waived by EPA), or added additional pollutants to the program, then likely new issues would have been created. However, in this instance no party has presented evidence that new issues exist for MYs 2017 and earlier as a result of the 2012 ZEV amendments. Therefore, EPA cannot deny CARB's request for a within the scope determination for MYs 2017 and earlier based on this criterion.

Therefore, based on the record before us, we cannot deny CARB's request for confirmation that its 2012 ZEV amendments, as they affect the 2017 and earlier MYs, are within the scope of previous waiver determinations. As such, we confirm CARB's request regarding the 2012 ZEV amendments as they affect 2017 and earlier MYs.

V. Consideration of Advanced Clean Car Regulations Under the Full Waiver Criteria

CARB's ACC program regulations include revisions to both California's LEV and ZEV programs. CARB's request seeks a waiver of preemption under section 209(b) of the Clean Air Act (CAA), 42 U.S.C. 7543(b) for the revisions to the LEV III program. CARB's request also seeks a waiver for the ZEV amendments included in the ACC program regulations. Subsequent to CARB's initial ACC waiver request, CARB's Executive Officer took action to formally adopt a “deemed to comply” regulation affecting the GHG component of the ACC package. CARB submitted this additional information to EPA and requested that EPA consider the “deemed to comply” regulation as part of CARB's pending ACC waiver request. EPA's application of the section 209(b) waiver request, including the “deemed to comply” regulation, is set forth below.

A. California's Protectiveness Determination

Section 209(b)(1)(A) of the Clean Air Act requires EPA to deny a waiver if the Administrator finds that California was arbitrary and capricious in its determination that its State standards will be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. EPA recognizes that the phrase “States standards” means the entire California new motor vehicle emissions program. Therefore, as explained below, when evaluating California's protectiveness determination, EPA compares the California-to-Federal standards. That comparison is undertaken within the broader context of the previously waived California program, which relies upon protectiveness determinations that EPA have previously found were not arbitrary and capricious.
50

50
In situations where there are no Federal standards directly comparable to the specific California standards under review, the analysis then occurs against the backdrop of previous waivers which determined that the California program was at least as protective of the federal program ((LEV II + ZEV) + GHG). See 71 FR 78190 (December 28, 2006), Decision Document for Waiver of Federal Preemption for California Zero Emission Vehicle (ZEV) Standards (December 21, 2006).

Traditionally, EPA has evaluated the stringency of California's standards relative to comparable EPA emission standards.
51

That evaluation follows the instruction of section 209(b)(2), which states: “If each State standard is at least as stringent as the comparable applicable Federal standard, such State standard shall be deemed to be at least as protective of health and welfare as such Federal standards for purposes of [209(b)(1)].”

51
36 FR 17458 (Aug. 31, 1971). (“The law makes it clear that the waiver requests cannot be denied unless the specific finding designated in the statute can properly be made. The issue of whether a proposed California requirement is likely to result in only marginal improvement in air quality not commensurate with its cost or is otherwise an arguably unwise exercise of regulatory power is not legally pertinent to my decision under section 209, so long as the California requirement is consistent with section 202(a) and is more stringent than applicable Federal requirements in the sense that it may result in some further reduction in air pollution in California.”). The “more stringent” standard expressed here in 1971 was superseded by the 1977 amendments to section 209, which established that California's standards must be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. The stringency standard remains, though, in section 209(b)(2).

To review California's protectiveness determination in light of section 209(b)(2), EPA conducts its own analysis of the newly adopted California standards to comparable applicable Federal standards. The comparison quantitatively answers whether the new

standards are more or less protective than the Federal standards. That comparison of the newly adopted California standards to the applicable Federal standards is conducted in light of prior waiver determinations. That is, the California-to-Federal analysis is undertaken within the broader context of the previously waived California program, which relies upon protectiveness determinations that EPA has not found arbitrary and capricious.
52

52
In situations where there are no Federal standards directly comparable to the specific California standards under review, the analysis then occurs against the backdrop of previous waivers which determined that the California program was at least as protective of the federal program ((LEV II + ZEV) + GHG). See 71 FR 78190 (December 28, 2006), Decision Document for Waiver of Federal Preemption for California Zero Emission Vehicle (ZEV) Standards (December 21, 2006).

A finding that California's determination was arbitrary and capricious under section 209(b)(1)(A) must be based upon “`clear and compelling evidence' to show that proposed [standards] undermine the protectiveness of California's standards.”
53

Even if EPA's own analysis of comparable protectiveness or that suggested by a commenter might diverge from California's protectiveness finding, that is not a sufficient basis on its own for EPA to make a section 209(b)(1)(A) finding that California's protectiveness finding is arbitrary and capricious.

“Once California has come forward with a finding that the procedures it seeks to adopt will not undermine the protectiveness of its standards, parties opposing the waiver request must show that this finding is unreasonable.”
MEMA I,
627 F.2d at 1124.

CARB has made a series of protectiveness determinations with regard to its ACC program. California made a protectiveness determination with regard to the 2012 ZEV and LEV amendments in CARB's Resolution 12-11, finding that the amendments would not cause the California motor vehicle emission standards, in the aggregate, to be less protective of public health and welfare than applicable federal standards.
55

CARB noted that this protectiveness determination is the logical extension of the comparable findings that were found to be sufficient in the analyses of California's previous protectiveness determinations for its ZEV, LEV, and GHG regulations.
56

As explained in CARB's waiver request, the ACC program will result in reductions of both criteria pollutants and GHG emissions that, in the aggregate, are more protective than the pre-existing federal standards. CARB's Resolution 12-11 also sets forth the Board finding that “It is appropriate to accept compliance with the 2017 through 2025 MY National Program as compliance with California's GHG emission standards up through the 2017 through 2025 MYs, once U.S. EPA issues their Final Rule on or after its current July 2012 planned release, provided that the GHG reductions set forth in U.S. EPA's December 1, 2011 Notice of Proposed Rulemaking for 2017 through 2025 model year passenger vehicles are maintained, except that California shall maintain its own reporting requirements.” Further, CARB's Resolution 12-21 sets forth that the CARB staff “prepared three separate Regulatory Notices * * * for these amendments [LEV III/GHG and ZEV] and presented them to the Board with a single coordinated analysis of emissions, costs, and associated environmental impacts and benefits.
57

CARB's Resolution 12-21 also resolves that the “recitals and findings contained in Resolution 12-11, are incorporated by reference herein.”
58

55

See
CARB's Resolution 12-11, EPA-HQ-OAR-2012-0562-0006 at 22. EPA notes that the CARB Board also resolved that it found that separate California standards and test procedures are necessary to meet compelling and extraordinary conditions.

In addition, at the time CARB adopted the “deemed to comply” regulation, the CARB Board found that such amendments do not undermine the Board's previous determination that the regulation's emission standards, other emission related requirements, and associated enforcement procedures are, in the aggregate, at least as protective of public health and welfare as applicable federal standards and are consistent with section 209 of the Clean Air Act.
59

Therefore, subsequent to the finalization of EPA's GHG regulation (August 31, 2012), and as part of the CARB Board's adoption of the “deemed to comply” rule on November 15, 2012, the Board resolved and determined “that the proposed regulations approved for adoption herein will not cause California motor vehicle emission standards, in the aggregate, to be less protective of public health and welfare than applicable federal standards.”

With regard to criteria pollutants, CARB notes that the primary fleet average emission requirement, beginning in 2015, declines every year to a fleet average NMOG plus NO
X
emission standard of 0.030 g/mi in 2025. CARB notes that this is clearly more stringent than the current federal Tier 2 fleet average NO
X
emission requirement with its implied fleet average NMOG and plus NO
X
requirement. In addition, the LEV III PM standards 3 mg/mi and 1 mg/mi are also significantly more stringent than the federal Tier 2 p.m. standards. CARB also notes that while there is no criteria emissions benefit with its ZEV requirements in terms of vehicle (tank-to-wheel—TTW) emissions since the LEV III criteria pollutant fleet standard is responsible for the emission reductions, but CARB notes that in terms of upstream emission impacts (well-to-wheel—WTW) there are emission reductions achieved from the ZEV requirements. There are no comparable federal standards.

CARB also notes that with regard to GHG emissions, the ACC program as a whole would provide major reductions in GHG emissions (e.g., by 2025 CO
2
emissions would be reduced by almost 14 million metric tonnes (MMT) per year, which is 12 percent from baseline levels). CARB's ACC waiver request, notes that the federal GHG standards do not become more stringent in the 2017-2025 MYs, as CARB's do. However, CARB states that it understands more stringent standards will “soon be finalized.”

At the time the Board adopted the “deemed to comply” amendments it had before it the “Staff Report: Initial Statement of Reasons demonstrating that if a National Program standard was theoretically applied only to California new vehicle sales alone, it might create a GHG deficit of roughly two million tons compared to the California standards.
61

CARB notes that there might be a GHG emission deficit if the National Program applied in California, and thus CARB's GHG emission standards are at least as stringent as the EPA GHG emission standards.

61
EPA-HQ-OAR-2012-0562-0374 at 3. CARB also notes that to the extent a manufacturer chooses not to exercise their National Program compliance option in California this would actually provide additional GHG benefits in California, so compliance in California can never yield fewer cumulative greenhouse gas reductions from the industry wide fleet certified in California.

1. Comments on CARB's Protectiveness Determination

The Dealers commented on CARB's protectiveness determinations for both its GHG emission standards and its ZEV regulations. At the outset, NADA claims that EPA must conduct a separate preemption waiver evaluation for each set of standards in the ACC program

(e.g., LEV III criteria pollutants, GHG, and ZEV). EPA notes that NADA did not address the preemption waiver request for the CARB LEV III standards.

In the context of considering the ACC standards individually, NADA states that EPA must reject CARB's GHG preemption waiver request because CARB's finding is premature. NADA maintains that CARB has not conducted the necessary investigation to support is protectiveness determination because EPA has now finalized its GHG emission standards. NADA claims that CARB's determination should measure the standards that exist at the time EPA makes its waiver decision. NADA contends that rather than allowing CARB to look at the program as a whole, CARB must be required to examine each standard before the Agency, including the GHG standards at issue. In the alternative, the commenter suggests that CARB's protectiveness determination is arbitrary and capricious since CARB itself cites the absence of the federal GHG standards as reason for its protectiveness determination. Finally, the commenter argues that CARB's conclusions are not backed by facts or analysis and contradict the actuality that emissions from other parts of the world and the United States affect global concentrations, and therefore concentrations in California. The Dealers state that it therefore follows that GHG concentrations in California will be reduced by a greater amount if reductions occur on a nationwide basis, rather than just statewide. Thus by definition, CARB standards for limiting GHG emissions from California cars are less protective than the applicable federal standards.

CARB's supplemental comments, in response to NADA's claims, note that California demonstrated that it was reasonable for the Board to determine that the California standards “as submitted” are, in the aggregate, as or more stringent than the applicable federal standards.
62

CARB suggests this was a relatively simple determination at the time of CARB's June 2012 waiver request because: (1) EPA's proposed 2017-2025 MY GHG standards were not finalized; (2) EPA had not proposed or finalized a 1 mg/mile PM standard and other criteria pollutant improvements for 2015 and later MYs; and (3) EPA has no ZEV program that may achieve an additional incremental wells-to-wheels criteria pollutant reduction. CARB states that this prior and timely Board determination remains sound despite the now finalized EPA GHG standards because (2) and (3) remain true and because EPA GHG standards: (1) do not account for upstream GHG emissions as does California's GHG program; (2) include vehicle multipliers for natural gas vehicles, effectively diluting federal standards vis a vis California's; and (3) contains relaxed criteria for GHG credits for mild hybrid-electric vehicle trucks, which also dilutes the federal standard. CARB also notes that to the extent manufacturers choose the EPA GHG standard compliance path to demonstrate compliance with California standards that results in essentially equal reductions (as stringent) of GHG emissions in California. Separately, CARB states that NADA's attempt to exclude CARB's LEV III standards from the “in the aggregate” protectiveness determination cannot be countenanced since this would render the phrase “in the aggregate” superfluous.

62
CARB submitted comment on November 14, 2012 (CARB supplemental comment). EPA-HQ-OAR-2012-0562-0373.

In addition, within CARB's Resolution 12-35, adopted on November 15, 2012, CARB addresses two issues raised by NADA's comments to EPA. CARB's Resolution 12-35 notes the question of whether the CARB Board failed to make a finding that California's passenger vehicle program remains as protective as applicable federal standards given the proposed “deemed to comply” rule on September 14, 2012 and also notes the question whether California's program is no longer as protective given the 2017 through 2025 MY National Program. First, it states that it sufficiently addressed NADA's protectiveness issues in its November 14, 2012 supplemental submittal to EPA. Within this submission, CARB noted that it was reasonable for the Board to determine that the California standards
as submitted
are, in the aggregate, as or more stringent that the applicable federal standards. CARB maintains that at the time of its June 2012 waiver submittal its protectiveness determination was a fairly simple one since EPA's 2017-2025 GHG standards were not finalized, EPA had not proposed nor finalized a 1 mg/mile PM standard and other criteria pollutant improvements for 2015 and later MYs, and EPA has no ZEV program that may achieve an additional incremental wells-to-wheels criteria pollutant reduction. CARB notes that the Board's determination remains solid despite the now finalized National Program rule because EPA still has no LEV III criteria pollutant/PM equivalent requirements and because EPA's GHG standards do not account for upstream GHG emissions as do California's, and because the National Program includes vehicle multipliers for natural gas vehicles and relax criteria for GHG credits for mild hybrid electric vehicle trucks.

EPA also received comment regarding CARB's protectiveness determination for its ZEV standards. The Dealers suggest that CARB failed to adequately provide a protectiveness determination, and such a determination is drawn into question given CARB's stated conclusions that there is no TTW emission benefits from ZEV and that the ZEV regulation does not provide any additional GHG emission reductions beyond the GHG standards. The Dealers claim that CARB's failure to make a protectiveness determination regarding its ZEV standard is inherently arbitrary and capricious.

CARB states that contrary to NADA's assertion that it must make an individual protectiveness determination regarding its ZEV amendments CARB believes that requiring California to show that each standard (including the ZEV standard) is at least as protective in the aggregate would in effect ignore the phrase “in the aggregate” in section 209(b). CARB states that is why it made one protectiveness determination. CARB notes that purpose of the ZEV regulation is to commercialize the technologies needed to meet long term goals even beyond the emission reductions anticipated by the LEV III program.

2. Is California's protectiveness determination arbitrary and capricious?

As described above, EPA's traditional analysis has been to evaluate California's protectiveness determination by comparing the new California standards, or amendments, to applicable EPA emission standards for the same pollutants. EPA notes that the “more stringent” standard expressed in 1971 was superseded by the 1977 amendments to section 209, which established that California's standards must be, in the aggregate, at least as protective of public health and welfare as applicable Federal standards. As noted above, this was intended to afford California the broadest possible discretion in designing is motor vehicle emission program. The comparison is undertaken within the broader context of the previously waived California program, which relies upon protectiveness determinations that EPA have previously found were not arbitrary and capricious.

EPA believes that the Dealers misapply our prior statement, made in EPA's 2009 GHG waiver decision, that the most straightforward reading of the comparison called for by the statute, between California and Federal standards, is an “apples to apples” comparison.
64

The stated purpose of the “apples to apples” phrase was to determine what the “applicable” Federal standards are for purposes of evaluating a protectiveness determination, in response to comments that the federal CAFE standards adopted by NHTSA should be considered applicable federal standards for purposes of this wavier criterion. EPA explained in the GHG waiver decision that “The term `applicable' has to refer to what Federal standards apply, and the most straightforward meaning is that they apply in the same way that the California standards apply, by setting limits on emissions of air pollutants.” Therefore, given the uniqueness of a CARB waiver request that includes interrelated standards applicable to the same vehicle category EPA believes CARB's approach of making one protectiveness determination for its ACC program is a reasonable approach permitted under section 209(b).
65

Although section 209(b)(2) informs EPA of the conclusion it must draw if each standard is at least as stringent as the comparable federal standard, EPA notes the protectiveness determination that CARB presents in a waiver request typically includes an implicit or explicit in the aggregate protectiveness determination since CARB typically examines whether its new standards (plural) undermine previous protectiveness determinations, which EPA evaluated in prior waiver decisions. In this context, once CARB presents an in the aggregate protectiveness determination EPA believes it appropriate to initially evaluate such standards in a side-by-side comparison with applicable Federal standards and then determine whether such standards are, in the aggregate, as protective as applicable Federal standards.

64

See
74 FR at 32750.

65
EPA also notes that CARB has provided complete information and determinations that even in the context of comparing individual standards their standards are as protective of public health and welfare as applicable Federal standards.

In the context of CARB's ACC standards this side-by-side analysis is simple. EPA has already determined that California was not arbitrary and capricious in its determination that the pre-existing California standards for light-duty vehicles and trucks, known as LEV II, is at least as protective as comparable federal standards, known as the Tier II standards.
66

In this instance, CARB has finalized new and more stringent criteria pollutant standards (LEV III) while the Tier II standards remain in place at the federal level. In the absence of newer EPA standards since the time of its prior waiver for CARB's LEV II standards there is a clear rational basis for CARB's determination that its standards will be at least as protective of human health and welfare as applicable federal standards.

66
68 FR 19811 (April 22, 2003) and Decision Document for Waiver of Federal Preemption for Low Emission Vehicle Amendments (LEV II) (April 11, 2003).

The Dealer's comments assert that CARB's protectiveness determination was premature because that assessment occurred before EPA finalized its own GHG emission standards. However, EPA believes that CARB's initial protectiveness determination (submitted to EPA in CARB's June 2012 waiver request) was not premature and was appropriate given the EPA standards in effect at that time. At the time CARB submitted its waiver request, EPA's GHG emission standards for the 2017 through 2025 MYs were the same for those MYs as for MY 2016, while CARB's were becoming more and more stringent over that period; therefore, CARB's protectiveness finding was reasonable at that time.

Subsequent to EPA's promulgation of its final GHG standards, in the context of CARB's “deemed to comply” regulation, CARB has provided an updated protectiveness determination (see Resolution 12-35) regarding the California GHG emission standards, in terms of the underlying benefits of CARB's program. EPA finds California to be correct in its determination that the “deemed to comply” regulation does not undermine CARB's determination that its regulations are in the aggregate as protective as EPA's standards. CARB's regulation will achieve, in the aggregate, equal or even additional GHG emission reductions in California relative to federal GHG standards, even if manufacturers choose to comply with the California regulations by complying with EPA's GHG emission standards. As noted above, EPA's National Program standards do not account for upstream GHG emissions as do California's and EPA's GHG standards includes vehicle multipliers for natural gas vehicles and relax criteria for GHG credits for mild hybrid electric vehicle trucks. EPA also believes that CARB correctly notes that even with the “deemed to comply” amendments, one or more manufacturers could still choose to continue demonstrating compliance in California under the existing California regulations. To the extent manufacturers choose EPA's GHG standards as the compliance path—in California—the California standard, by definition would yield at least, essentially equivalent GHG reductions, so California's standards cannot be less stringent.

The Dealers seem to suggest that with EPA's GHG standards there will be a greater reduction of GHG emissions compared to the California GHG emission standards. California's protectiveness determination applies only to the protectiveness of CARB's emission standards, in California, compared to applicable federal standards. EPA believes that the Dealers ignore the obvious, that all stakeholders, including California, recognize the need for reductions of GHG emissions, as well as emissions of other pollutants, on a national basis. The federal GHG emission standards, applied in 50 states, will generally result in more emission reductions than CARB standards applied solely in California. If California were required to achieve equal emission results (with reductions counted only in California) to a federal program this would render 209(b) unusable. The relevant comparison is between the emission reductions achieved in California under the California program versus the emission reductions in California under the comparable federal program. Emissions reductions in other states are not considered, which is appropriate because the waiver decision affects only California's emission standards, not the federal standards that exist regardless of EPA's decision. EPA believes, and the record contains no evidence otherwise, that the reductions due to CARB's GHG emission standards in California versus the reductions of the comparable federal GHG emission standards in California, demonstrates that CARB's GHG emission standards are at least as protective as applicable federal standards. EPA notes that NADA raised similar arguments in the context of EPA's within the scope waiver decision, issued on June 14, 2011, for CARB's GHG emission amendments that included a “deemed to comply” provision for GHG emission standards during the 2012 through 2016 MYs. EPA noted “Thus, at the very least, compliance with California's GHG standards under the revised regulations will result in the same, if not more, emission reductions than would occur in the absence of the California standards. NADA provides no evidence that CARB's standards are less protective than the applicable Federal

standards. As such, NADA fails to present any evidence or make any showing that the amendments undermine California's previous determination that its standards, in the aggregate, are at least as protective of public health and welfare as applicable Federal standards.”
67

67
76 FR 34693, 34696 (June 14, 2011).

With regard to CARB's ZEV amendments EPA believes that CARB has provided a reasoned basis for their determination that the ZEV regulations are as protective or public health and welfare as comparable federal requirements, which for ZEV are nonexistent. In EPA's 2006 ZEV waiver proceeding, EPA conducted its traditional analysis to compare California's newly enacted ZEV standards to a similar lack of applicable federal standards. At that time California found, and EPA deemed reasonable, that the addition of the ZEV standards did not render California's LEV II program, for which a waiver had previously been granted, less protective than the federal Tier II program. In addressing the Alliance of Automobile Manufacturers' petition for reconsideration with respect to this issue, EPA stated that “the words `standards' and `in the aggregate' in section 209(b)(1)(A) * * *, at minimum, include all the standards relating to the control of emissions for a category of vehicles (
e.g.,
passenger cars, etc.) subject to CARB regulation, particularly where the standards are designed to respond to the same type of pollution.”
68

California's ZEV and GHG emission standards are an addition to its LEV program. EPA has not received any comment to suggest that the existence of either of these additional regulatory components undermines the protectiveness of CARB's LEV III emission standards. Although the Dealers suggest that “consumers facing a CARB-constrained mix at their local dealership may elect to buy a CARB-exempted brand, to purchase a late-model used vehicle, or defer vehicle purchases altogether,” EPA believes that the Dealers have failed to present any legal argument as to why EPA should take this into consideration within the waiver criteria. We also find that the Dealers have failed to provide evidence, under any standard of proof, as to whether such outcomes would ultimately impair the protectiveness of CARB's emission standards. EPA believes it is appropriate, and certainly reasonable, for CARB to evaluate its standards in the aggregate when the nature of its regulations are interrelated and the regulations are submitted to EPA as one ACC program. Although NADA suggests that CARB failed to make an individual protectiveness determination for its ZEV standards, EPA believes this is of no significance in light of the overall protectiveness of CARB's emission standards and the lack of an applicable federal ZEV program. The Dealers mere contentions, which CARB reasonably refutes in its supplement comments,
69

that there is no criteria emission benefit from the ZEV proposal in terms of TTW emissions, and that the ZEV regulation does not provide GHG emission reductions in addition to the LEV III GHG regulation, suggest no reason to find that CARB's ACC program is any less protective of public health and welfare because of the existence of such ZEV standards.

3. Section 209(b)(1)(A) Conclusion

Based on the record before EPA, we cannot find that CARB was arbitrary and capricious in its finding that the California ACC program standards, including the LEV III criteria pollutant and GHG emission standards along with its ZEV amendments are, in the aggregate, at least as protective of public health and welfare as applicable federal standards.

B. Does California need its standards to meet compelling and extraordinary conditions?

Under section 209(b)(1)(B) of the Act, EPA cannot grant a waiver if EPA finds that California “does not need such State standards to meet compelling and extraordinary conditions.” EPA has traditionally interpreted this provision as requiring a consideration of whether California needs a separate motor vehicle program to meet compelling and extraordinary conditions. However in EPA's March 6, 2008 denial of CARB's GHG waiver request (GHG waiver denial), EPA limited this interpretation to California's motor vehicle standards that are designed to address local or regional air pollution problems. EPA determined that the traditional interpretation was not appropriate for standards designed to address a global air pollution problem and its effects and that it was appropriate to address such standards separately from the remainder of the program. EPA then found that California did not need such standards to meet compelling and extraordinary conditions. The interpretation adopted in the March 6, 2008 waiver denial was before EPA for reconsideration when CARB resubmitted its GHG waiver request and EPA announced a new opportunity for hearing and public comment on February 12, 2009.

74 FR 7040 (February 12, 2009).

Set forth below is a summary of EPA's departure from the traditional interpretation of section 209(b)(1)(B) in the GHG waiver denial along with EPA's return to the traditional interpretation (confirmed today) in EPA's waiver of preemption of CARB's GHG standards on July 8, 2009 (GHG waiver).
71

Because EPA received comment suggesting that CARB's GHG and ZEV standards do not meet the requirements of section 209(b)(1)(B), EPA believes it useful to recount the interpretive history associated with both GHGs and traditional local and regional air pollutants to explain why EPA believes that section 209(b)(1)(B) should be applied in the same manner for all air pollutants.

71
74 FR 32744 (July 9, 2009).

As explained below, EPA finds that the opponent of the ACC waiver has not met its burden of demonstrating why CARB no longer has a need for its motor vehicle emissions program under EPA's interpretation of section 209(b)(1)(B). Although EPA is not adopting the Dealers suggested interpretation, EPA also finds that the opponent of the waiver has not met its burden of demonstrating that CARB does not have the need for either its GHG or ZEV standards.

1. EPA's March 6, 2008 GHG Waiver Denial

In the March 6, 2008 waiver denial, EPA provided its reasoning for changing its long-standing interpretation of this provision, as it pertains to California standards designed to address global air pollution. EPA described its longstanding interpretation in some detail, stating that:

Under this approach EPA does not look at whether the specific standards at issue are needed to meet compelling and extraordinary conditions related to that air pollutant. For example, EPA reviewed this issue in detail with regard to particulate matter in a 1984 waiver decision.
72

In that waiver proceeding, California argued that EPA is restricted to considering whether California needs its own motor vehicle program to meet compelling and extraordinary conditions, and not whether any given standard is necessary to meet such conditions. Opponents of the waiver in that proceeding argued that EPA was to consider whether California needed

these PM standards to meet compelling and extraordinary conditions related to PM air pollution.

72
49 FR 18887 (May 3, 1984).

The Administrator agreed with California that it was appropriate to look at the program as a whole in determining compliance with section 209(b)(1)(B). One justification of the Administrator was that many of the concerns with regard to having separate state standards were based on the manufacturers' worries about having to meet more than one motor vehicle program in the country, but that once a separate California program was permitted, it should not be a greater administrative hindrance to have to meet further standards in California. The Administrator also justified this decision by noting that the language of the statute referred to “such state standards,” which referred back to the use of the same phrase in the criterion looking at the protectiveness of the standards in the aggregate. He also noted that the phrase referred to standards in the plural, not individual standards. He considered this interpretation to be consistent with the ability of California to have some standards that are less stringent than the federal standards, as long as, per section 209(b)(1)(A), in the aggregate its standards were at least as protective as the federal standards.

The Administrator further stated that in the legislative history of section 209, the phrase “compelling and extraordinary circumstances” refers to “certain general circumstances, unique to California, primarily responsible for causing its air pollution problem,” like the numerous thermal inversions caused by its local geography and wind patterns. The Administrator also noted that Congress recognized “the presence and growth of California's vehicle population, whose emissions were thought to be responsible for ninety percent of the air pollution in certain parts of California.”
73

EPA reasoned that the term compelling and extraordinary conditions “do not refer to the levels of pollution directly.” Instead, the term refers primarily to the factors that tend to produce higher levels of pollution—“geographical and climatic conditions (like thermal inversions) that, when combined with large numbers and high concentrations of automobiles, create serious air pollution problems.”

73 FR 12156, 12159-60.

The Administrator summarized that under this interpretation the question to be addressed in the second criterion is whether these “fundamental conditions” (i.e. the geographical and climate conditions and large motor vehicle population) that cause air pollution continued to exist, not whether the air pollution levels for PM were compelling and extraordinary, or the extent to which these specific PM standards will address the PM air pollution problem.
75

75
73 FR at 12159-60.

However in the GHG waiver denial, EPA limited this interpretation to California's motor vehicle standards that are designed to address local or regional air pollution problems. EPA determined that the traditional interpretation was not appropriate for standards designed to address a global air pollution problem and its effects.
76

76
EPA recently reaffirmed that the traditional interpretation still applied for motor vehicle standards designed to address air pollution problems that are local or regional in nature. 71 FR 78190, 78192 (December 28, 2008);
see also
71 FR 78190 and Decision Document for Waiver of Federal Preemption for California Zero Emission Vehicle Standards, at 34.

With respect to a global air pollution problem like elevated concentrations of GHGs, EPA's GHG waiver denial found that the text of section 209(b)(1)(B) was ambiguous and did not limit EPA to this prior interpretation. In addition, EPA noted that the legislative history supported a decision to “examine the second criterion specifically in the context of global climate change.” The legislative history:

[I]ndicates that Congress was moved to allow waivers of preemption for California motor vehicle standards based on the particular effects of local conditions in California on the air pollution problems in California. Congress discussed “the unique problems faced in California as a result of its climate and topography.” H.R. Rep. No. 728, 90th Cong. 1st Sess., at 21 (1967). See also Statement of Cong. Holifield (CA), 113 Cong. Rec. 30942-43 (1967). Congress also noted the large effect of local vehicle pollution on such local problems. See, e.g., Statement of Cong. Bell (CA) 113 Cong. Rec. 30946. In particular, Congress focused on California's smog problem, which is especially affected by local conditions and local pollution. See Statement of Cong. Smith (CA) 113 Cong. Rec. 30940-41 (1967); Statement of Cong. Holifield (CA), id. at 30942. See also,
MEMA I,
627 F. 2d 1095, 1109 (DC Cir., 1979) (noting the discussion of California's “peculiar local conditions” in the legislative history). Congress did not justify this provision based on pollution problems of a more national or global nature in justifying this provision.
77

77
73 FR at 12161.

Relying on this, and without any further significant discussion of either congressional intent or how this new approach properly furthered the goals of section 209(b), EPA determined that it was appropriate to:

[R]eview California's GHG standards separately from the remainder of its motor vehicle emission control program for purposes of section 209(b)(1)(B). In this context it is appropriate to give meaning to this criterion by looking at whether the emissions from California motor vehicles, as well as the local climate and topography in California, are the fundamental causal factors for the air pollution problem—elevated concentrations of greenhouse gases—apart from the other parts of California's motor vehicle program, which are intended to remediate different air pollution concerns.

EPA then applied this interpretation to the GHG standards at issue in that waiver proceeding. Having limited the meaning of this provision to situations where the air pollution problem was local or regional in nature, EPA found that California's GHG standards do not meet this criterion. EPA also found that the elevated concentrations of GHGs in California are similar to concentrations elsewhere in the world, and that local conditions in California such as the local topography and climate and the number of motor vehicles in California are not the determinant factors causing the elevated GHG concentrations found in California and elsewhere. Thus, EPA found that California did not need its GHG standards to meet compelling and extraordinary conditions, and denied the GHG waiver.

EPA also considered an alternative interpretation, where EPA would consider “the effects in California of this global air pollution problem in California in comparison to the rest of the country, again addressing the GHG standards separately from the rest of California's motor vehicle program.” Under this alternative interpretation, EPA considered whether the impacts of global climate change in California were significant enough and different enough from the rest of the country such that California could be considered to need its GHG standards to meet compelling and extraordinary conditions. EPA determined that the waiver should be denied under this alternative interpretation as well.

2. EPA's July 9, 2009 GHG Waiver

In EPA's July 9, 2009 GHG waiver, the Agency determined that the better approach was to review California's need for its new motor vehicle emissions program as a whole to meet compelling and extraordinary conditions, and not to apply this criterion to specific standards, or to limit it to standards designed to address only local or regional air pollution problems. EPA reasoned that the traditional approach to interpreting this provision was the best approach for considering a waiver directed to GHG emission standards, as well as a waiver for standards directed to address local or regional air pollution problems.
78

Therefore, EPA rejected the interpretation that was applied in the March 6, 2008 waiver denial and stated it should no longer be followed.

78
The traditional interpretation of section 209(b)(1)(B) is certainly not “unambiguous precluded” by the language of the statute. See
Entergy Corp.
v.
Riverkeeper, Inc.,
129 S.Ct. 1498 (2009) (“That view governs if it is a reasonable interpretation of the statute—not necessarily the only possible interpretation, nor even the interpretation deemed most reasonable by the

courts.
Chevron U.S.A. Inc.
v.
Natural Resources Defense Council, Inc.,
467 U.S. 837, 843-844 (1984).”) (“It seems to us, therefore, that the phrase “best available,” even with the added specification “for minimizing adverse environmental impact,” does not unambiguously preclude cost-benefit analysis.”).
Carrow
v.
Merit Systems Protection Board,
564 F.3d 1359 (Fed. Cir. 2009) (“[W]e are obligated to give controlling effect to [agency's] interpretation if it is reasonable and is not contrary to the unambiguously expressed intent of Congress”, citing
Entergy Corp.
).

EPA reasoned that the traditional interpretation was the most straightforward reading of the text and legislative history of section 209(b). Congress decided in 1977 to allow California to promulgate individual standards that are not as stringent as comparable federal standards, as long as the standards are “in the aggregate, at least as protective of public health and welfare as applicable federal standards.” This decision by Congress requires EPA to allow California to promulgate individual standards that, in and of themselves, might not be considered needed to meet compelling and extraordinary circumstances, but are part of California's overall approach to reducing vehicle emissions to address air pollution problems.

Further, we noted that EPA is to determine whether California's protectiveness determination is arbitrary and capricious under section 209(b)(1)(A), and whether California does not need “such State standards” to meet compelling and extraordinary conditions under section 209(b)(1)(B). The natural reading of these provisions led EPA to consider the same group of standards that California considered in making its protectiveness determination. While the words “in the aggregate” are not specifically mentioned in section 209(b)(1)(B), EPA explained that it does refer to the need for “such State standards,” rather than “each State standard” or otherwise indicate a standard-by-standard analysis.

We also noted that EPA's GHG waiver denial had determined that this provision was appropriately interpreted to consider California's standards as a group for standards designed to address local or regional air pollution problems, but should be interpreted in the opposite fashion for standards designed to address global air pollution problems. The text of the provision, however, draws no such distinction, and provides no indication other than Congress intended a single interpretation for this provision, not one that varied based on the kind of air pollution problem at issue.

EPA also explained that the GHG waiver denial had considered the legislative history, and determined that Congress was motivated by concern over local conditions in California that led to local or regional air pollution problems, and from this EPA determined that Congress intended to allow California to address these kinds of local or regional air pollution problems, but no others. However, upon a reexamination of the legislative history EPA found that the determination noted above ignores the main thrust of the text and legislative history of section 209(b), and improperly reads too much into an absence of discussion of global air pollution problems in the legislative history. The structure of section 209, both as adopted in 1967 and as amended in 1977, is notable in its focus on limiting the ability of EPA to deny a waiver, and thereby preserves discretion for California to construct its motor vehicle program as it deems appropriate to protect the health and welfare of its citizens. The legislative history indicates Congress quite intentionally restricted and limited EPA's review of California's standards, and its express legislative intent was to “provide the broadest possible discretion [to California] in selecting the best means to protect the health of its citizens and the public welfare.”
79

The DC Circuit recognized that “[t]he history of the congressional consideration of the California waiver provision, from its original enactment up through 1977, indicates that Congress intended the State to continue and expand its pioneering efforts at adopting and enforcing motor vehicle emission standards different from and in large measure more advanced than the corresponding federal program. In short, to act as a kind of laboratory for innovation. * * * For a court [to limit California's authority] despite the absence of such an indication would only frustrate the congressional intent.”

H.R. Rep. No. 294, 95th Cong., 1st Sess. 301-302 (1977).
See MEMA I,
627 F. 2d at 1110-11.

80

MEMA I,
627 F. 2d at 1111.

EPA also determined that it was fully consistent with the expressed intention of Congress to interpret section 209(b)(1)(B) the same way both for standards designed to address local and regional air pollution problems, and standards designed to address global air pollution problems. Congress intended to provide California the broadest possible discretion to develop its motor vehicle emissions program. Neither the text nor the legislative history of section 209(b) indicates that Congress intended to limit this broad discretion to a certain kind of air pollution problem, or to take away all discretion with respect to global air pollution problems.
81

In addition, EPA reasoned that applying the traditional interpretation to GHG standards does not change the basic nature of the compromise established by Congress—California could act as the laboratory for the nation with respect to motor vehicle emission control, and manufacturers would continue to face just two sets of emissions standards—California's and EPA's.

81
This broad interpretation of section 209(b) is similar to the broad reading the Court provided to section 302(g) of the Clean Air Act when it held that the term “air pollutant” included greenhouse gases, rejecting among other things the argument that Congress limited the term to apply only to certain kinds of air pollution.
Massachusetts
v.
EPA,
549 US 497, 532 (2007) (footnote 26).

EPA further explained that this interpretation was consistent with Congressional purpose, as compared to the interpretation adopted in the GHG waiver denial relied on the discussion in the legislative history of local conditions in California leading to air pollution problems like ozone. While this was properly read to support the view that section 209(b) should be interpreted to address California's need for a motor vehicle program as a whole,
