BRIEF OF NATURAL GAS VEHICLE COALITION
AND CALIFORNIA NATURAL GAS VEHICLE
COALITION AS AMICI CURIAE
IN SUPPORT OF RESPONDENTS

INTERESTS OF AMICI CURIAE

The Natural Gas Vehicle Coalition (““NGVC”) and the
California Natural Gas Vehicle Coalition (“CNGVC”")
respectfully submit this joint brief in accordance with
Supreme Court Rule 37.3.' NGVC,.a nonprofit trade organ-

' Pursuant to Rule 37.3 of the Rules of this Court, the parties have
consented to the timely filing of all amici curiae briefs in this matter. The
parties’ letters of consent have been lodged with the Clerk of the Court.
Pursuant to Rule 37.6 of the Rules of this Court, amici curiae state that
this brief was not authored in whole or in part by counsel for any party
and that no person or entity, other than amici curiae and their mem-
bers, made a monetary contribution to the preparation or submission of
this brief.

2

ization headquartered in Washington, D.C., is a national
organization dedicated to the development of a growing,
sustainable, and profitable market for vehicles powered by
natural gas and hydrogen. NGVC represents more than 180
companies interested in the promotion and use of natural gas
and hydrogen as transportation fuels, including: engine,
vehicle, and equipment manufacturers; natural gas
companies; fleet operators; and service providers. CNGVC, a
non-profit trade organization headquartered in Sacramento,
California, seeks to promote the continued expansion of the
natural gas vehicle market in California, the State that leads
the nation in natural gas vehicle usage. The outcome of this
action may determine whether the South Coast Air Quality
Management District (“SCAQMD” or “South Coast”) and
other localities and government entities throughout the
country may impose reasonable restrictions on commercial
and municipal use of fleet vehicles as a critical means to
attaining public health air quality standards that also promote
the market for cleaner vehicles and fuels.

SUMMARY OF ARGUMENT

For more than thirty years, and through multiple revisions,
Congress has established a framework dependent upon dual
federal and state regulation under the Clean Air Act to deliver
clean and healthy air to the nation. Under this approach, the
federal government establishes nationwide public health air
quality standards and the States retain the responsibility
for devising the strategies to meet these standards in a
timely fashion.

Motor vehicle emissions—and particularly heavy-duty
diesel emissions—pose significant air quality challenges,
especially in the South Coast region. The continued violation
of public health air standards in this region has severe public
health consequences. Natural gas vehicles are becoming
increasingly prevalent because they are far cleaner than their

3

conventionally fueled counterparts and they are cost-effec-
tive. They are an important part of the air quicity solution
and lend themselves particularly well to being used in
centrally fueled fleets.

The South Coast Air Quality Management District’s Fleet
Rules foster the deployment of this cleaner technology to
vehicles used to deliver municipal and commercial services.
The rules are reasonable attainment strategies and a vital part
of meeting the region’s clean air goals.

The plain language of the Clean Air Act’s preemption
provision, the structure of that statute, Congress’ underlying
purpose, and the interpretive case law all support a narrow
reading of the Section 209 preemption provision. The Act’s
preemption is limited to motor vehicle exhaust emissions
standards. Congress made clear that such standards are
different from other, non-preempted, requirements. Congress
sought to strike a balance between the need for a national
standard, the unique situation in California, and the needs of
areas around the nation to come into attainment with public
health air quality standards. The limited effect of the pre-
emption provision is consistent with Congress’ other
objectives of deferring to California’s motor vehicle
regulation leadership and the retention of state authority and
responsibility for delivering clean air. South Coast’s Fleet
Rules do not impose new exhaust emissions standards upon
manufacturers, but are a reasonable attainment strategy for
achieving healthy air. They are not preempted by the Act.

ARGUMENT

SECTION 209A) DOES NOT PREEMPT THE
SOUTH COAST AIR QUALITY MANAGE-
MENT DISTRICT’S FLEET RULES

When Congress legislates in a field traditionally occupied
by the States, the Court has consistently “start{ed] with the
assumption that the historic police powers of the States were

4

not to be superseded by the Federal Act unless that was the
clear and manifest purpose of Congress.” Rice v. Santa Fe
Elevator Corp., 331 U.S. 218, 230 (1947). State law is
preempted when Congress intends to “occupy the field”
through a pervasive regulatory scheme or when there is an
explicit conflict with a federal statute where it is impossible
to comply with both the state and federal law. Crosby v.
National Foreign Trade Council, 530 U.S. 363, 372-73
(2000). And where there is an express preemption provision,
no need exists to turn to a theory of implication. Motor and
Equipment Mfrs Ass'n, Inc. v. EPA, 627 F.2d 1095, 1107
(D.C. Cir. 1979) (““MEMA”). The scope of preemption is
best assessed “by examining the federal statute as a whole
and identifying its purpose and intended effects.” Crosby v.
National Foreign Trade Council, 530 U.S. at 373. See also
Egelhoff v. Egelhoff ex rel. Breiner, 532 U.S. 141, 147
(2001); California Div. of Labor Standards Enforcement v.
Dillingham Constr., N.A., Inc., 519 U.S. 316, 325 (1997),

A. The Clean Air Act Contemplates Dual Federal
and State Regulation

For more than thirty years, and through multiple revisions,
Congress has established a framework dependent upon dual
federal and state regulation under the Clean Air Act. Under
this approach, the federal government establishes nationwide
public health air quality standards and the States retain the
responsibility for devising the strategies to meet these
standards in a timely fashion. See, e.g., 42 U.S.C. § 7401(a);
42 U.S.C. § 7410; Chevron, U.S.A., Inc. v. Natural Res.
Defense Council, Inc., 467 U.S. 837, 845-46 (1984); Train
v. Natural Res. Defense Council, Inc., 421 U.S. 60,
64-65 (1975).

Except in limited areas, Congress expressly provided that
States or their political subdivisions had the right to “adopt or
enforce any standard or limitation respecting emissions of air

ss

-

5

pollutants or any requirement respecting control or abatement
of air pollution.” 42 U.S.C. § 7416. Indeed,

[t]he Act gives the Agency no authority to question the
wisdom of a State’s choices of emission limitations if
they are part of a plan which satisfies the standards of
Section 110(a)(2). . . . Thus, so long as the ultimate
effect of a State’s choice of emissions limitations is
compliance with the national standards for ambient air,
the State is at liberty to adopt whatever mix of emissions
limitations it deems best suited to its particular situation.

Train, 421 U.S. at 79. Moreover, States may even sub-
mit implementation plans more stringent than federal law
requires. Union Elec. Co. v. EPA, 427 U.S. 246,
249-50 (1976).

Thus, the issue in this case must be assessed against the
backdrop of a vital role for States in solving the nation’s air
pollution problem. Moreover, States can face significant
sanctions if they fail to attain the national public health air
quality standards in a timely fashion. See, e.g., 42 U.S.C.
§§ 7410(m), 7509(a)-(b); Sierra Club v. EPA, 311 F.3d 853
(7th Cir. 2002); Sierra Club v. EPA, 294 F.3d 155 (D.C. Cir.
2002); Motor Vehicle Mfrs. Ass'n of U.S., Inc. v. New York
State Dep't of Envt'l Conservation, 17 F.3d 521, 527 (2d Cir.
1994) (““MVMA"). Congress has encouraged States to
employ a wide variety of inventive methods to meet their
obligations under the Act. A State can implement programs
for improved public transit, restrict certain roads and lanes
for passenger buses ‘or high occupancy vehicles, and create
traffic flow improvement programs that achieve emission
reductions. 42 U.S.C. § 7408(f)(1)(A). Likewise, States can
create economic incentive programs that include “incentives
and requirements to reduce vehicle emissions.” 42 U.S.C. §
751 la(g)(4).

B. Natural Gas Vehicles Provide Important Clean
Air Attainment Benefits for States and Local-
ities to Protect Public Health

1. Diesel Exhaust Air Pollution Poses a Sig-
nificant Public Health Concern in Southern
California

The significant and particular challenge posed by auto-
mobile emissions has long been recognized. See, e.g.,
Edmund S. Muskie, Role of the Federal Government in Air
Pollution Control, 10 Ariz. L. Rev. 17, 19 (1968)
(“automobile exhaust was cited [in the 1963 hearings] as
responsible for some 50 percent of the national air pollution
problem” (quoting Special Senate Subcomm. on Air and
Water Pollution, 88th Cong., 2d Sess., Steps Toward Clean
Air 3 (Comm. Print 1964))). The significant health concerns
posed by motor vehicle pollution, and particularly diesel
exhaust, continue today.

California now has a population of over 34 million people,
and as of the year 2000 had 23.4 million registered motor
vehicles. California Air Resources Board, California's Air
Quality History Key Events (2003), available at http://www.
arb.ca.gov/html/brochure/history.htm. Two hundred eighty
billion vehicle miles were traveled in the State that year. /d.
The South Coast Air Basin is the only area of the country
classified by the Environmental Protection Agency (“EPA”)
as an “extreme nonattainment area”. JA 80. In that area, on-
road motor vehicles contribute more than half of all
hydrocarbons, nitrogen oxides, and carbon monoxide to the
emissions inventory. JA 80. In 1998, the year for which
SCAQMD had the most recent data when considering the
Fleet Rules, the area within SCAQMD’s jurisdiction
exceeded federal standards for ozone, carbon monoxide or
particulate matter on a total of 97 days—far more frequently
than in any other area of the United States. JA 244-45. A
recent study by the University of California Los Angeles

7

Institute of the Environment fourd that air pollution is
estimated to cause up to 9,000 premature deaths each year in
the Los Angeles basin and that smog continues to worsen.
ULCA Institute of the Environment, Southern California
Environmental Report Card 2003 24 (2003).

Diesel emissions are a particular health concern. EPA has
found that:

[t]he pollution emitted by diesel engines contributes
greatly to our nation’s continuing air quality problems.
Even with more stringent heavy-duty highway engine
standards set to take effect in 2004, these engines will
continue to emit large amounts of nitrogen oxides and
particulate matter, both of which contribute to serious
public health problems in the United States. These
problems include premature mortality, aggravation of
respiratory and cardiovascular disease, aggravation of
existing asthma, acute respiratory symptoms, chronic
bronchitis, and decreased lung function. Numerous
studies also link diesel exhaust to increased incidence of
lung cancer. We believe that diesel exhaust is likely to
be carcinogenic to humans by inhalation and that this
cancer hazard exists for occupational and environmental

susceptibility. See Executive Order No. 13045, Protection of

As EPA’s former Administrator has noted, “[e]very day in
America, 24 million children travel safely to and from school
on 444,000 school buses — that’s four billion miles each year,

2. Natural Gas Vehicles Provide a Clean, Cost
Effective, and Increasingly Prevalent Low
Pollution Alternative

Amici Alliance of Automobile Manufacturers, et. al.,
(“Alliance Brief’) assert without support that the emissions
difference between diesel and natural gas vehicles has been
“neutralized” and that the Fleet Rules as a result are a
“throwback” to an uninformed era. Alliance Br. 3, 10. The
data tell a very different story. Natural gas vehicles, such as
those encouraged by the Fleet Rules, provide an important
strategy for addressing these severe and continuing pollution
concerns. Natural gas vehicles can be significantly cleaner on
ozone-forming emissions than gasoline vehicles, and even
cleaner than those with respect to their diesel counter-
parts. See, e.g., Dep't of Energy, Reasons to Buy Alternative
Fuel Vehicles, at http://www.ccities.doe.gov/vbg/fleets/about_
buying.html (last visited Oct. 21, 2003). Because of the
reduced complexity of their emissions control systems due to
their inherently clean performance, emissions reductions from
natural gas vehicles are more reliable and durable than those

10

from conventionally-fueled vehicles.’ Patricia Monahan,
Pollution Report Card: Grading America’s School Bus Fleet
26, Union of Concerned Scientists (2002). They also do not
have emissions from the engine itself or during refueling—
known as vapor evaporative emissions—which can constitute
a significant part of the emissions from gasoline or diesel
fueled engines. 59 Fed. Reg. 50,042, 50,070-71 (1994).

A recent study conducted by the University of California at
Riverside and Los Angeles found that children riding on
diesel buses meeting current requirements had two to five
times higher exposures to harmful pollutants than those riding
on natural gas buses. California Air Resources Board,
Characterizing The Range Of Children's Pollutant Exposure
During School Bus Commutes, available at hitp://www.arb.
ca.gov/research/schoolbus/schoolbus.htm (last visited Oct.
10, 2003). Indeed, the natural gas buses were cleaner than
even the best controlled diesels. /d. Natural gas school buses
emit 90 percent less toxic soot than conventional new diesel-
powered buses and are over 98 percent cleaner than older
diesel buses. Monahan, Pollution Report Card: Grading
America’s School Bus Fleets, supra at x. In considering the
Fleet Rules, SCAQMD staff explained that “one diesel refuse
truck is estimated to have the same toxicity as up to 74
corresponding natural gas refuse trucks ....” JA 130.

While some of these advantages for natural gas vehicles
will be lessened when tougher new heavy duty diesel
standards promulgated by EPA phase in, these regulations
apply only to new engines and it will be many years before
the bulk of the diesel vehicles on the road turns over to these
cleaner vehicles. 66 Fed. Reg. at 5012. Fleets will not fully
comply with that rule until the year 2030. Jd. at 5014.

One of California’s clean car standards, the AT-PZEV standard,
requires manufacturers to certify the emissions durability for 15 years or
150,000 miles. Cal. Code Regs. tit. 13, § 1962(c)(2)A), (C)-(D) (2003).

——

Moreover, diesel engine manufacturers, including petitioner
EMA’s members, have repeatedly raised doubts about their
ability to conform with the significantly cleaner standards that
will take effect for vehicles manufactured in 2007 and after.
See, e.g., National Petrochemical & Refiners Ass'n v. EPA,
287 F.3d 1130, 1136-1138 (D.C. Cir. 2002); Brief of
Petitioner Cummins Inc. at 4, National Petrochemical &
Refineries Ass'n, 287 F.3d 1130 (D.C. Cir. 2002) (No. 01-
1052) (“Technology does not exist today to meet the
standards for heavy-duty diesel engines. Moreover, EPA has
not identified any path toward development of such
technology by 2007... .”).

Alternative fueled vehicles are becoming increasingly
prevalent because they are both a sound environmental and a
cost effective choice. While diesel engine manufacturers
struggle to meet the upcoming new emissions standards,
recent government testing has also shown that some natural
gas heavy-duty engines are already twice as clean as the 2007
EPA standards—and cleaner than any diesel engine available
today. Dep't of Energy, The Next Generation Natural Gas
Vehicle Activity, DOE/GO-102003-1779 (Sept. 2003). One
natural gas vehicle manufacturer recently completed a
purchase contract with the Metropolitan Transit Authority of
Los Angeles County to supply between 200 and 600 buses
with an engine targeted to achieve 40 percent lower nitrogen
oxide emissions than the best equivalent low-emissions diesel
engines certified to date. Press Release, Cummins Westport
Inc., New Cummins Westport Engine Selected by Los
Angeles for up to 600 Buses (July 18, 2003), available at
http://www.cumminswestport.com/press/index.php. This en-
gine is also expected to be certified for particulate matter at a
level that is 80 percent lower than those set by EPA for
regulations for transit buses. /d. Indeed, the cleanest internal
combustion engine light-duty vehicle commercially available
at the time of the consideration of the Fleet Rules was a

12

compressed natural gas powered Honda Civic, which is on
average 90 percent cleaner than the average new 2000 model
year vehicle. JA 86-87.

The Fleet Rules are readily achievable. There are almost
130,000 natural gas vehicles on the nation’s roads today.
Leslie Eudy, Natural Gas in Transit Fleets: A Review of the
Transit Experience 2, National Renewable Energy Laboratory

pollution challenges. Justice Breyer reviewed the history of
these efforts and found that:

[t}hose persons, for example, who opposed the 1970
Act’s insistence on a 90% reduction in auto emission
pollutants, on the ground of excessive cost, saw the
development of catalytic converter technology that
helped achieve substantial reductions without the
economic catastrophe that some had feared.

Whitman v. American Trucking Ass'ns, Inc., 531 U.S. 457,
492 (2001) (Breyer, J., concurring).

Congress has also long recognized that, for several reasons,
fleets can be particularly cost-effective places to achieve
emissions reductions and pioneer new technologies:

fleets represent a logical spot to introduce clean-fuel
vehicles. Fleet operators have central refueling facilities
that should simplify the transition to new fuels. They
can provide regular professional maintenance for early
models. And per vehicle, they drive twice as many
miles as vehicles used by the general public. This
affords fleet vehicles the best opportunity to take
advantage of the fuel savings that certain alternative
fuels (particularly natural gas and electricity) may
provide.

Air Act Amendmenis of 1990, 21 Envtl L. 1947, 2002 (1991)
(citing Office of Technology Assessment, Catching Our
Breath: Next Steps for Reducing Urban Ozone 188 (1989)).

Significant incentives for developing alternative fleets have
been created by the federal government. These incentives
have occurred with, at a minimum, the acquiescence of
Congressional appropriators. The Federal Aviation Adminis-
tration, for instance, has established a $17.3 million grant
program pursuant to the Aviation Investment and Reform Act
for the 21st Century, 49 U.S.C. § 47136, to encourage the use

14

of alternative fuel vehicles in fleets operating at airports, and
the Secretary of Transportation provides regular reports to
Congress on this program. See Dep’t of Transporta-
tion, Report to Congress: Inherentiy Low-Emission Airport
Vehicle Pilot Program (Nov. 2001), available at http://
www2.faa.gov/arp/app600/ileav/RTCag.htm; FAA Selects 10
Airports for $17.3 Million in Grants for AFVs 5-6, New Fuels
& Vehicles Report (June 7, 2001).

Airport use of alternative fueled vehicles provides a
particular demonstration of their benefits. Many airports
operate in areas not meeting public health air quality
standards, and airports frequently have huge motor vehicle
emissions inventories. Los Angeles International Airport, for
instance, is the second largest industrial smog source in the
Los Angeles Area. Coalition for Clean Air, Fast Facts 3,
available at http://www.coalitionforcleanair.org/cca/facts.htm
(last visited Nov. 6, 2003). Airport motor vehicle fleets today
can have even more intensive use than Congress recognized
in 1990, amounting to ten to twenty times the fuel use of
private vehicles. A typical airport shuttle bus travels ap-
proximately 60,000 miles per year. Clean Vehicle Education
Foundation, AFVs in the Airport Shuttle Industry: Char-
acterization of a Niche Market 17, available at http://www.

Dallas/Fort Worth has a draft policy that would require all
commercial ground transportation vehicles to consist of 100%
Ultra Low Emissions Vehicle certified vehicles or the
equivalent by 2007. Dallas/Fort Worth International Airport,

shuttles, and other courtesy vehicles that are added to a
company’s fleet operating at the Dallas/Fort Worth Airport
must be at a minimum LEV or the equivalent after 30 days of
the plan’s adoption. /d. Municipalities likewise have chosen

Pe)

to contract for services with fleets that have made the
commitment to transition to lesser-polluting alternative fuel
vehicles. See, e.g., City of Palm Desert Exclusive Franchise
Contract to Perform Solid Waste Collection and Recycling
Services (July 1, 1995)“CONTRACTOR agrees that a
minimum of 50% of new engines for its entire fleet will be
alternative fuel vehicles.); Franchise Agreement Between the
City of Alameda and Alameda County Industries AR, Inc. for
Solid Waste, Recyclable Materials and Organic Materials
Services (July 3, 2002)(“On the Commencement Date of this
Agreement, at a minimum, fifty percent (50%) of the Solid
Waste Collection vehicles and fifty percent (50%) of the
Recyclable Materials and Organic Materials Collection
vehicles used regularly on Collection routes by Contractor
shall be Clean Alternative Fuel Vehicles.”). For many States
and localities, finding these cost-effective fleet-based
reductions is an enormously beneficial attainment strategy
and—for some regions—a vital part-of their pathway towards
compliance with the Act’s requirements.

C. The SCAQMD Fleet Rulec Are Not A Pre-
empted “Standard” Under Section 209(a)

1. The Plain Language of the Clean Air Act
Shows that Congress Limited Preemption
to the Precise and Narrow Concept of
“Standards” Rather than to Any Action
Affecting Emissions

Within the context of state obligations to meet the national
public health air quality standards under the Act, Congress
assigned the duty to the federal government to set national
motor vehicle emissions standards, 42 U.S.C. § 7521, but it
also reserved for California the ability to develop such
standards and allowed other states to follow California’s lead.
42 U.S.C. § 7543. Congress was precise in the language that
it used to limit state actions in this regard. Except. for

16

vehicles regulated under the California scheme, the Clean Air
Act provides, “[nJo 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.” 42 U.S.C. § 7543(a)
(emphasis added). Section 209(b) allows California to
receive a waiver from EPA to issue standards to control
emissions from new motor vehicles provided that the
standards are at least as protective, in the aggregate, as the
Federal standards. 42 U.S.C. § 7543(b). Any State may then
adopt standards that are identical to California’s more
stringent standards controlling emissions, 42 U.S.C. § 7507.

When arrayed against the carefully crafted limitations on
fleet use adopted by South Coast, it is plain that the
preemption language of the statute itself is inapplicable. The
Fleet Rules only require public agencies, those contracting to
provide services on behalf of public agencies, or specific
types of licensed private fleets to select among certain lower-
emitting vehicles already certified as meeting emissions
standards by the California Air Resources Board (“CARB”).
See, e.g., JA 27.

Congress limited its preemption in Section 299 to the
narrow phiase “standard relating to the control of emissions.”
Despite the efforts of the petitioners and their amici to reach
the circumstances here by conflating anything resulting in the
control of emissions with the much more particular concept
of a “standard”, see Pet Br. 25; Alliance Br. 7, the text of the
Clean Air Act does not bear them out. Surely the Act would
not, for example, go so far as to prevent local transportation
agencies from choosing to purchase natural gas transit buses
themselves or from deciding upon purchasing smaller, less
expensive, and more fuel-efficient vehicles that happen to
have lower emissions as well.

The second sentence of Section 209(a) prohibits States
from creating conditions precedent to the initial retail sale,

titling, or registration of a new motor vehicle. 42 U.S.C.
§ 7543(a). The Fleet Rules, however, only require fleet
Owners to purchase vehicles that are either (1) classified
under CARB’s regulations as “low emission” vehicles or (2)
operate on an alternative fuel. See, e.g., Rule 1191(e) JA
28). They are “expressly designed to work in tandem with
CARB’s certification process.” JA 219. Therefore, the Fleet
Rules do not prevent manufacturers from selling non-low
emission vehicles, nor do the Rules require that the manu-
facturer sell a specified percentage.* Rather they require a
special class of purchasers to buy vehicles that are already in
the market.”

Petitioners and amici concede that certain “in-use” motor
vehicle controls, such as carpool lanes and idling restrictions,
are not preempted under the Act. Pet. Br. 5; Alliance Br. 11.
But other controls adopted by States and local governments
are far more subtle, such as those that provide special clean
fuel licenses for use of carpool lanes by alternative fueled
vehicles, Va. Code. Ann. § 33.1-46.2 (Michie Supp. 2003), or
even the creation of tax incentives or subsidies to encourage
the purchase of this type of vehicle. Twenty-nine States have
adopted tax and other incentive programs that are designed to
create the preference for the purchase of alternative-fueled

* Each Fleet Rule also contains an exception that allows fleet operators
to purchase “higher emission” vehicles in the event that no certified
alternative fuel vehicle exists. See, e.g., Rule 1191(g) (JA 30).

* Nor do the Fleet Rules single out diesel-fueled vehicles because of
antipathy toward this particular technology. In passing these provisions,
SCAQMD’s Governing Board resolved that its staff should “continue to
evaluate all engine technologies including conventional diesel . . . and
make recommendations for the potential inclusion of these technologies”
in the Fleet Rules. SCAQMD Resolution No. 00-XX at 5. Staff are
required by this Resolution to return to the Governing Board with
proposed amendments in the event that conventionally fueled vehicle
engines achieve particular CARB-certified emissions and toxics reduc-
tions targets. /d. at 7.

vehicles, such as natural gas cars and trucks. See Clean
Cities Program, Department of Energy Compilation, at
http://www.ccities.doe.gov/vbg/progs/laws.cgi (last visited
Nov. 6, 2003). Incentives exist in various forms from coast to
coast. California has adopted the Carl Moyer Air Quality
Standards Attainment Program, which provides funds for the
purchase of vehicles that achieve a 30 percent reduction of
nitrogen oxide emissions compared to current emissions
standards. California Environmental Protection Agency, The
Carl Moyer Memorial Air Quality Standards Attainment
Program Guidelines (2003), available at http://www.arb.
ca.gov/msprog/moyer/2003moyerguide.pdf. Licenses given
by the City of Dallas permit alternative fuel taxicabs and
shuttles to be up to seven years old, whereas conventionally
fueled vehicles may only be up to five years old. Dallas City
Code § 44-7.2.1(a). - Washington, D.C. will only contract for
school bus transportation services with companies whose
fleets have more recent, and therefore lesser polluting,
models. Monahan, supra, at 17. Petitioners and their amici’s
suggestion that Section 209(a) creates a clear dividing line
between a federal sphere pertaining to any and all actions
affecting motor vehicles before their initial sale and a limited
state sphere of permissible regulation after sale makes no
sense in view of these kinds of state and local actions, which
are intended to have the effect of reducing emissions, but are
not themselves emission standards.

The Section 209 preemption provision is tethered to the
substantive content of the authorization for federal motor
vehicle emissions standard setting in Section 202. That entire
provision is written in terms of narrow numerical standards
for motor vehicles. 42 U.S.C. § 7521. Throughout Section
202, Congress uses “standards” to refer to quantitative limits,
see 42 U.S.C. § 7521(3)(A), and Section 202(g) requires that
regulations contain “standards which provide that such

19

emissions from a percentage of each manufacturer’s sales

volume of such vehicles” must not exceed specified levels.
42 U.S.C. § 7521(g).°

The text of the Act is plain that the preemption provision is
narrowly circumscribed. Congress clarified that, “[nJothing
in this part shall preclude or deny to any State or political
subdivision thereof the right otherwise to control, regulate, or
restrict the use, operation, or movement of registered or
licensed motor vehicles.” 42 U.S.C. § 7543(d)(emphasis
added). Nor did Congress limit this clarification to those
actions “not affecting emissions,” something it plainly could
have done. South Coast’s Fleet Rules fall within this
authorization to regulate use, operation, or movement. Since
the Fleet Rules are restrictions on use that apply to
commercial or public fleet operators and not directly to the
manufacturers, they fall within this protected area of state and
local authority.

This limiting construction of Section 209(a) is not changed
by Congress’ choice in that subsection of the phrase “relating
to” the control of emissions. As this Court stated in Egelhoff,
that while “relating to” indicates that the subject is broadly
construed, there is an outer limit—the term cannot be
construed to make “preemption turn on infinite connections.”
532 U.S. at 147. Similarly, Justice Scalia, joined by Justice
Ginsburg, recognized in a concurrence that the phrase is of
littke moment to preemption analysis because “everything is

* EPA has recently declined to regulate carbon dioxide motor vehicle
emissions under section 202, finding in part that it lacks statutory
authority to engage in such regulation. 68 Fed. Reg. 62,922 (2003).
Since federal authority to grant a motor vehicle emissions waiver to States
is premised upon the scope of that authority, and preemption is intended
to be “coextensive” with this waiver authority, MEMA, 627 F.2d at 1107,
preemption arguably would not apply were SCAQMD to have based its
regulation on addressing global warming concerns stemming from carbon
dioxide emissions.

related to everything else.” Dillingham Constr., N.A., Inc.,
519 U.S. at 336 (1997) (Scalia, J. concurring); accord N.Y.
State Conference of Blue Cross & Blue Shield Plans v.
Travelers Inc., 514 U.S. 645, 655-56 (1995). Here, it is plain
that Congress in its preemption language was addressing
narrow vehicle emissions controls rather than any strategy
employed by a State which might result in reduced motor
vehicle emissions overall.

Moreover, Congress consistently distinguished between
this narrow concept of “standards” and other types of
requirements, such as “accompanying enforcement proce-
dures,” throughout each of the provisions in Section 209. See
City of Chicago v. Environmental Defense Fund, 511 U.S.
328, 338 (1994) (citing Keene Corp. v. United States, 508
U.S. 200, 208 (1993)) (“It is generally presumed that
Congress acts intentionally and purposely when it includes
particular language in one section of a statute and omits it in
another.”); see also Bailey v. United States, 516 U.S. 137, 146
(1995)(“‘a legislature is presumed to have used no superfluous
words”). Sections 209(a), 209(b)(1)(C), and 209 (e)(2)(B)
each differentiate between the phrase “standards” and other
types of requirements. 42 U.S.C. §§ 7543(a), 7543(b)(1)(C),
and 7543(e)(2)(B). Congress must have intended for the
specific term “standard” to refer to a specific type of quanti-
tative requirement respecting emissions with a direct impact
on air quality, rather than to a broad, all encompassing term.

The Circuit Courts have consistently adopted this reading
of the Act, emphasizing the specificity of the terminology
employed by Congress. As the U.S. Court of Appeals for the
District of Columbia Circuit has explained:

[t}hese references [in subsection (a)] to efforts at
enforcement would have been unnecessary if Congress
intended that “standards” meant any regulation relat-
ing to motor vehicle emissions control. . . . Congress
intended the word “standards” to mean quantitative

21
levels of emissions rather than regulations involving
certification or in-use maintenance restrictions. ... . The

Senate Report on the Air Quality Act of 1967, discussing
the preemption provision, mentions “standards” for
hydrocarbons, nitrogen oxides, and carbon monoxide in
obvious reference to the numerical limitations on those
pollutants.

MEMA, 627 F.2d 1107, 1112 (D.C. Cir. 1979) (citing S. Rep.
No. 90-403, at 32 (1967)); accord Motor Vehicle Mfrs. Ass'n
of US., Inc. v. DEC, 79 F.3d 1298, 1305-06 (2d Cir.

emption for mechanisms employed to enforce state adopted
standards). See also EPA Opinion on Issues Raised by Am.

narrow breadth of term “standard” in sections 209 and 177 in
contrast to enforcement language, while finding requirements
as to numbers of vehicles meeting certain quantitative
emissions levels are within the ambit of “standard” under
the Act).’

2. The Text and Structure of Other Clean Air
Act Provisions Support Affirming the
Lower Courts’ Opinions

Other provisions of the statute bear out the limited nature
of its preemption. Section 116, which retains state authority
other than as limited in Section 209, refers to a much broader
set of circumstances than just “standards relating to the
control of emissions.” It refers to “standards or limitations”

’ EPA's Opinion Letter finds that “production requirements” as to the
number of vehicles meeting a certain emissions level are within the scope
of “emissions standards” under sections 209 and 177 because, among
other reasons, an indication of market penetration is central to evaluating
feasibility and cost issues under Section 202. These issues are not
implicated by the Fleet Rules here, which merely require the selection
among already certified models.

22

as well as to “any requirement respecting control or
abatement of air pollution.” 42 U.S.C. § 7416 (emphasis
added). Congress is presumed to intend the use of such
starkly different language and could have been so expansive
had it intended the preemption provision to have such a broad
sweep. See City of Chicago, 511 U.S. at 338."

These careful distinctions are preserved throughout the
Act. Section 242, which sets forth certain requirements for
the clean fuel vehicle program, could not be clearer in
distinguishing between “standards”—referring to numerical
emissions from motor vehicle exhaust—and “other require-
ments.” Compare 42 U.S.C. § 7582(a) and 42 U.S.C.
§ 7582(b).

In its regulations setting forth the requirements to imple-
ment the Clean Fuel Fleet Program (“CFFP’’) provisions of
Section 246, 42 U.S.C. § 7586, EPA went to great pains to
distinguish between production requirements and fleet-based
incentives, similar to those at issue here. EPA explained:

[t]he legislative history of the 1990 amendments to the
[Clean Air Act] indicates that, in adopting the [Clean
Fuel Fleet Program], Congress made a clear choice
between two alternatives: requiring auto manufacturers
to produce and sell [Clean Fuel Vehicles], or creating
a market for [Clean Fuel Vehicles] and for clean
alternative fuels by requiring fleet operators to purchase

* Congress included in the Act a variety of other arguably relevant
provisions designed to increase the types of tools available for States
and industry to achieve cleaner air. See 42 U.S.C. § 751 la(c)(4)-(5)
(authorizing States to impose transportation control measures to reduce
motor vehicle emissions); 42 U.S.C. § 7586 (authorizing state limitations
on certain fleet operators as part of a Clean Fuel Fleet Program). The
Clean Fuel Fleet Program provisions of Section 246 are merely a pilot
designed to foster and test these approaches.

63 Fed. Reg. 20,103, 20,104 n.4, 20,105 (1998) (citing A
Legislative History of the Clean Air Act Amendments of 1990,
vol. | at 903). The United States, as amicus, confuses these
issues by attempting to read this history as a prohibition on
the Fleet Rules, rather than as a long-standing Congressional
acknowledgement of the appropriateness and limited purpose
of approaches of this nature.” U.S. Br. 20.

Petitioners incorrectly state that Section 246, the CFFP,
itself preserves Section 209%a)’s preemption of fleet pur-
chasing requirements. Pet Br. 42-43. Section 246, to be sure,
bears some similarity to SCAQMD’s actions by requiring
States to submit a State implementation plan (SIP) revision
establishing a clean-fuel vehicle program if the State is
classified as a “covered area” as defined in the section. 42
U.S.C. § 7586. However, Congress did not prohibit a State
from using a similar program, on its own initiative, to address
air quality problems, nor did it prohibit States from adopting
even more stringent provisions. Congress understood that
these provisions were not the exclusive realm for addressing
and promoting alternative fueled vehicles and that States
could choose to implement a similar program even when not
required to do so by Section 246." Moreover, Congress has

” To the extent that the views of the United States differ with these
arguments, the positions presented in its amicus brief are litigating
positions that have not met the prerequisites for deference to statutory
interpretation. See Geier v. American Honda Motor Co., Inc., 529 U.S.
861, 911 (2000) (Stevens, J., dissenting) (citing Christensen v. Harris
County, 529 U.S. 576, 587 (2000)).

'° A similar situation exists with regard to incentive programs. Section
249% f)(2) permits States to revise their SIP to provide incentives for the
sale or use of clean-fuel vehicles that are produced, sold, and distributed
in California. Many States already have incentive programs (financial
incentives to purchasers of clean-fuel vehicles, exemptions from high
occupancy vehicle requirements, and parking preferences) that Section

24

authorized other federal actions to secure fleet-based
pollution reductions. See, e.g., Energy Policy Act of 1992, 42
U.S.C. § 13201 et seq. (requiring fuel providers and state
governments to acquire a certain percentage of alternative
fueled vehicles and requiring the Department of Energy to
evaluate promulgating rules for private and municipal fleets
to acquire a certain percentage of alternative fueled vehicles).
Therefore, Section 246 signifies nothing more than Congress’
recognition that a clean-fuel fleet program is an effective tool
to improve air quality in an area."

3. Narrow Congressional Concern About a
“Third Car” Is Not Implicated by South
Coast’s Action

Congress’ limited purpose in preempting one aspect of
motor vehicle regulation should inform the Court's evaluation
of these provisions. The District Court below thoroughly
reviewed this history. Pet. App. 10a-13a. It shows that
Congress recognized that California had special air quality
needs justifying a new motor vehicle emissions program

=

249 lists as permissible. 42 U.S.C. § 7489(f)(3); pp. 14-15, supra. If Peti-
tioner and Amici’s analysis is adopted, such incentive programs used
by States independent of the Federal incentive programs would be
preempted.

'' The United States, as amicus, argues that Section 249, which
establishes the California pilot test program for light-duty trucks and
light-duty vehicles, signals that programs like the Fleet Rules are
preempted. U.S. Br. 27. However, the California pilot test program is a
narrow program that requires automobile manufacturers to produce and
sell a certain number of vehicles to the California public. 42 U.S.C.
§ 7589; see American Auto. Mfrs. Ass'n v. Cahill, 973 F. Supp. 288, 300
n.1l (N.D.N.Y. 1997). The provision does not speak to whether a
requirement that operators of light-duty and heavy-duty fleets purchase

certain low emission vehicles is preempted. Moreover, the Second Circuit_

has found the preemption reference to “standards” in Section 209 did not
extend to the separate authority for Clean Fleets plans. MVMA, 17 F.3d
at 532.

stricter than the federal program and that the State should be
afforded the broadest discretion possible in selecting the best
means to protect the health of its citizens. See H.R. Rep. No.
90-728 (1967).'* Additionally, Congress appreciated that
California-was a pioneer in setting emissions standards and
could continue to serve as a laboratory for further controls.
Engine Mfrs. Ass'n v. EPA, 88 F.3d 1075, 1079-80 (D.C. Cir.
1996); MEMA, 627 F.2d at 1110-11 (citing S. Rep. No. 90-
403, at 33 (1967)). Indeed, California has been involved in
these efforts since 1946 and first developed comprehensive
standards in 1957. MEMA, 627 F.2d at 1107, 1109 n.26.
California’s severe air quality challenges continue to this day,
with it consistently rated among the areas with the worst
ozone problems in the Nation. JA 80.

Congress sought only to avoid the potential confusion and
burden that would be created by the requirement that
manufacturers or drivers going into new States abide by
standards for a “third car” other than the California or federal
approaches. David P. Currie, Motor Vehicle Air Pollution:
State Authority and Federal Pre-Emption, 68 Mich. L. Rev.
1083, 1090-91 (1969-70). The scope of this preemption is
limited and was designed to protect against that one
purpose—to ensure auto manufacturers would not potentially
have to create 50 different classes of cars to meet each State’s
different emissions control standard. Congress wanted to
avoid placing an “undue burden on the automobile manu-
facturing industry.” MVMA, 17 F.3d at 527; see also Pet.
App. 26a; H.R. Rep. No. 90-728, at 21 (1967) (preemption is
“necessary in order to prevent a chaotic situation from
developing in interstate commerce in new motor vehicles”);
Jan Stevens, Air Pollution and the Federal System: Responses
to Felt Necessities, 22 Hastings L. J. 661, 674 (1970-71). At

Emission Control: The Clean Fuel Vehicle, 15 Va. Envtl. L. J. 213, 224-

the same time, Congress sought to strike a balance between
the need for a national standard, the unique situation in
California, and the needs of areas around the nation to come
into attainment with public health air quality standards.

EPA has long recognized—at least until the filing of the
United States’ brief here—Congress’ narrow purpose with
respect to preemption of engine regulation. In commenting
upon a parallel preemption provision for aircraft engines,
Section 233, 42 U.S.C. § 7573, EPA opined by letter that, if a
court reviewing a state regulation were to find “no necessary
impairment of the operator’s ability to operate and test the
engine, it [would] seem[] quite likely that [the court] would
find the state action not to contravene the Congressional
purpose of barring varying state and local regulations which
dictate how engines are designed, built and operated.”
People of State of California v. Dep't of the Navy, 624 F.2d
885, 888 (9th Cir. 1980), aff’ g 431 F. Supp. 1271, 1286-87
(N.D. Cal. 1977). The Ninth Circuit in Dep't of the Navy
affirmed a District Court finding that state regulations
affecting emissions from engine test cell housings had
“absolutely no effect upon the design, manufacture, and/or
operation of aircraft engines,” and therefore were not
preempted by the Clean Air Act. Dep't of the Navy, 431 F.
Supp. at 1287.

Similarly, the Fl et Rules do not run afoul of Con-
gressional intent by creating a third vehicle. Rather, they are
consistent with the deference Congress provided to California
to develop its own strategy for reducing its air pollution and
the tools reserved to the States more generally to tevelop
attainment strategies. This Court should be equally reluctant
to find that a particular strategy by California exceeds the
scope of the State’s authority. A measure should only be

found to be preempted if it clearly falls within the scope of
Congress's intent to preempt state authority.’ Rice, 331
U.S. at 230.

The effort by petitioners and their amici to preclude any
“attempt to ‘reduce harmful emissions from certain motor
vehicle fleets’” goes too far. Brief for The Chamber of
Commerce of the United States of America as Amicus at 12.
See also Pet. Br. 28 (“even when a state law lacks this express
reference to emission characteristics . . . , it may nonetheless
be preempted if it is linked in some other manner to control of
motor vehicle emissions .. . .”). Congress’ purpose was to
equip States with the tools to meet their air quality obligations
while affording predictability to manufacturers. Nowhere is
there evidence that Congress intended to completely
hamstring state efforts at addressing emissions. Congress
was very aware of the distinction it was creating between
“standards” and other practices such as use and maintenance
and its impact even on the unique problems of the Los
Angeles region. See Hearings on Automotive Air Pollution
before the Subcomm. On Air and Water Pollution of the
Senate Comm. on Public Works, 90th Cong., Ist Sess. 115
(1967) (statement of Sen. Baker) (“You don’t think the
doctrine of Federal preemption would prevent the State of

'’ Petitioners’ invocation of the “third car” prohibition, Pet. Br. 31, is
svmewhat mystifying, in view of the record below, which indicates that
three out of the four major engine manufacturers are already making
several different engine models that qualify for purchase under South
Coast's Fleet Rules. See JA 221-34. There are currently more than 50
commercially available makes and models of NGVs. See The Natural
Gas Vehicle Coalition, 2002 Natural Gas Vehicle Coalition Purchas-
ing Guide, available at http://www.atdc.doe.gov/pdfs/ngy_guide02.pdf.
While Amici American Road & Transportation Builders Ass'n et al.

reliance on diesel vehicles for fleets, Br. 24-25, none of these constitute a
preference or mandate for an otherwise non-certified vehicle.

California or Los Angeles County from making additional

4. The Act Permits Staite and Local Govern-
ments to Impose Reasonable Restrictions on
Commercial Fleet Activity as an Attainment
Strategy

The Clean Air Act's plain language, structure, and purpose
all support the retention of authority by SCAQMD to impose
reasonable requirements on commercial and municipal fleets
as vital parts of an attainment strategy for achieving public
health air standards. In a strikingly similar case, the Southern
District of New York evaluated emissions-related restrictions
on licensed taxi cabs imposed by the New York City Taxi and
Limousine Commission. That court explained that:

both the history and text of the Act show that the. . .
preemption section was made not to hamstring localities
in their fight against air pollution but to prevent the
burden on interstate commerce which would result if,
_instead of uniform standards, every state and locality
were left free to impose different standards for exhaust
emission control devices for the manufacture and sale of
new Cars.

Allway Taxi, Inc. v. City of New York, 340 F. Supp. 1120, 1124
(S.D.N.Y.), aff'd., 468 F.2d 624 (2d. Cir. 1972). That Court
further reasoned that the Clean Air Act does not “preclude a
locality from setting its own standards for the licensing of
vehicles for commercial use within that locality.” /d. The
“burden of compliance” with such standards is “on individual
owners and not on manufacturers and distributors.” /d.

This same analysis pertains to the Fleet Rules here. As the
District Court explained, “[t}he Fleet Rules accept as a given
the existing CARB vehicle standards; they merely require
fleet operators to choose from among the least polluting of

29

CARB-certified, available vehicles. The Rules impose no

new emission requirement on manufacturers whatsoever... .”
Pet. App. 21a.

The fleet rules adopted by the SCAQMD are not standards
relating to the control of emissions and therefore are a valid
exercise of the State’s police power.

CONCLUSION

For the foregoing reasons, the judgment below should be
affirmed.
