INTRODUCTION

Respondents Appalachian Power Company, ef a/., do not
question the importance of the Clean Air Act or the public
health and environmental goals of that Act. As the
Environmental Protection Agency (“EPA” or “Agency”)
continues to regulate air pollution to ever more stringent
levels in response to uncertain predictions of health risk,
however, the incremental health benefits of these regulations
become harder to ascertain and the costs of erroneous or
unnecessary regulations — including the risk of indirect health
effects and excessive compliance costs — increase. We are
concerned that, in such situations, failure to consider all of

the impacts of a regulatory decision on society may result in
standards that do more harm than good for the public health.

This case concerns one such situation: the EPA
Administrator’s revision of National Ambient Air Quality
Standards (“NAAQS”) for ozone and particulate matter
(“PM”) under § 109 of the Clean Air Act (“CAA” or “Act”).
In this case, EPA revised the existing NAAQS for ozone and
PM, standards that EPA previously issued as “requisite to
protect the public health” with an “adequate margin of
safety” against the same health risks for which the Agency
now believes more stringent standards are needed. CAA §
109(b). In both rulemakings, the Administrator was faced
not with “demonstrated adverse effects” on the public, but
rather with a range of uncertain predictions of “health risk.”
Based on this record, the Administrator made a public health
“policy” judgment that “uncertainties associated with
inconclusive scientific and technical information” and
“hazards that research has not yet identified” justified revised
standards reflecting greater margins of safety. See, e.g., 62
Fed. Reg. 38857, OJA 2; id 38653, PMJA 3.

In making this decision, the Administrator concluded that
the Act forbade her from considering factors that would
allow her to make a reasoned public health policy judgment
when confronted with the “uncertainties” and “inconclusive”
information concededly at issue here. These prohibited
factors include the indirect health, environmental and
economic impacts of her decision. See 62 Fed. Reg. 38882,

> Cf Ethyl Corp. v. EPA, 541 F.2d 1, 13-15 (D.C. Cir. 1976) (en banc)
(comparing the “adverse effects” language of pre-1977 § 108(a), which
“require[d] proof of demonstrable harm,” with a “will endanger” standard
comparable to that added to § 108(a) in 1977, which authorizes regulation
in response to “significant risk of harm’”’).

OJA 27; Brief For Respondent EPA, at 49-51 (D.C. Cir. No.
97-1441).

The Administrator’s policy judgment, made with blinders
to the overall consequences of those decisions, resulted in
some of the most costly regulatory decisions ever made by a
federal agency. The record indicates monetary costs to meet
the new standards may be up to $150 billion each year,"
almost an order of magnitude greater than the $18 billion
total spent on medical research in the United States the year
these standards were promulgated.’ Equally important,
efforts to attain these standards have potentially adverse
public health and environmental effects, including an
increased risk of premature mortality.

These tradeoffs are part of any sound risk management
decision that promotes the public health. Based on a flawed
interpretation of the CAA grounded in D.C. Circuit
precedent, however, the lower court concluded that the
Administrator must ignore these impacts on society when
managing public health risk under § 109 of the Act. See
American Trucking Ass'ns v. EPA, 175 F.3d at 1040, App.
18a (citing Lead Industries Ass'n v. EPA, 647 F.2d 1130,
1148 (D.C. Cir. 1980)).

For the following reasons, this Court should reverse the
D.C. Circuit’s interpretation of the CAA in this case. The
lower court’s decision improperly prohibits EPA from
exercising sound risk management judgment under CAA
§ 109 that will promote the public health. Furthermore, the
Court should instruct EPA that it must consider the broad

Ozone & Particulate Standards 9 (1997), OJA 3323.

impacts on society of its regulatory decisions managi
health “risks” through the NAAQS program, so that the
Agency’s NAAQS decisions will maximize the public good.
We do not advocate that consideration of costs be substituted
for te paper of health effects, but rather that EPA be
required to consider all factors relevant to managing public
health risk, in order that NAAQS decisions aaa. the
public health consistent with the statutory purposes of the
Clean Air Act.

STATEMENT

I. THE NAAQS PROGRAM

The purpose of the Act, as set forth in § 101(b)(1), is “to
protect and enhance the quality of the Nation’s air resources
so as to promote the public health and welfare and productive
capacity of its population.” This statutory language reflects
congressional intent that Clean Air Act programs achieve a
balance of social, economic and _ environmental
considerations.

In CAA §§ 108 and 109, the operative regulatory
provisions at issue here, Congress called for the
establishment of NAAQS for air pollutants that may
reasonably be anticipated to “endanger” public health or
welfare. Under § 109(b)(1), primary NAAQS are to reflect a
level of air quality “the attainment and maintenance of which
in the judgment of the Administrator, based on such criteria
and allowing an adequate margin of safety, are requisite to
protect the public health.”

* Secondary NAAQS are to be set at a level that, in the Administrator’s
judgment, protects the public welfare from “known or anticipated adverse
effects.” CAA § 109(b)(2). In this case, EPA set secondary NAAQS at
the same level as the primary NAAQS. Judicial review of both the

6

The “criteria” to which § 109(b) refers is an informational
document that must “accurately reflect the latest scientific
knowledge useful in indicating the kind and extent of all
identifiable effects on public health or welfare which may be
expected from the presence of such pollutant in the ambient
air, in varying quantities.” CAA § 108(a)(2) (emphasis
added). While the effects on “public health or welfare”
addressed by the air quality criteria document must be related
to the “presence of such pollutant in the ambient air,” there
are otherwise no other limits on the nature of the effects
addressed by the criteria document. Rather, this document is
to cover “all identifiable effects” on the “public health or
welfare.” Jd. (emphasis added).

The criteria document is also to “include information on
... those variable factors (including atmospheric conditions)
which ... may alter the effects on public health or welfare of
such air pollutant.” /d § 108(a)(2)(A). Furthermore,
§ 108(b)(1) provides that “/s]imultaneously with the issuance
of [the] criteria” document, EPA must issue information on
the “cost of installation and operation, energy requirements,
emission reduction benefits, and environmental impact” of
methods for pollution control or prevention. CAA
§ 108(b)(1) (emphasis added). All of this information is to
be made available before EPA undertakes a NAAQS
rulemaking.

Once NAAQS are set, the Administrator must review
them and the underlying criteria document every five years
and revise them “as may be appropriate” in accordance with
§§ 108 and 109(b). CAA § 109(d)(1). To help with standard

primary and secondary NAAQS was sought. The lower court remanded

the secondary NAAQS to EPA along with the primary NAAQS. 175 F.3d
at 1040, App. 18a.

revision, the Administrator appoints “an independent
scientific review committee” to provide advice on the
scientific basis for setting and revising NAAQS. This
committee is to advise the Administrator on, among other
things, additional knowledge required to determine the
“adequacy” of existing standards and the “basis” for any
revisions to them, and on “any adverse public health,
welfare, social, economic, or energy effects which may result
from various strategies for attainment and maintenance” of
revised NAAQS. CAA § 109(d)(2)(C) (emphasis added).

When the air quality standards program was initially
enacted in 1970, the Senate Report described the NAAQS as
reflecting a “reasonable degree of protection” in the face of
uncertain science, rather than reflecting absolute protection
from any and all predicted risks.’ When it amended the Act
in 1977, Congress emphasized the importance of protecting
public health, but made clear that “public health” protection
does not embrace a “no-risk philosophy” because that
“ignores all economic and social consequences and is
impractical.”* In 1990, Congress extensively amended the
Act, but did not amend § 109, § 108(a) or § 108(b).

3671 (Sen. Muskie) (When there is “no threshold on health effects ... it
[is] very difficult then to apply absolute health protection.”).

Il. EPA’S POLICY DECISION TO REVISE THE
OZONE AND PM NAAQS

In the rulemakings at issue in this case, EPA replaced the
existing 1-hour ozone NAAQS with a more stringent 8-hour
standard.” EPA also replaced the existing particulate matter
NAAQS based on a PMjo size indicator with standards for
both fine particles (PM2 5) and for coarse particles (PMjo)."°

As the lower court explained, “EPA regards ozone
definitely, and PM likely, as non-threshold pollutants, i.e.,
[pollutants] ... that have some possibility of some adverse
health impact (however slight) at any exposure level above
zero.”'' For each of these asserted non-threshold pollutants,
EPA was presented with a choice among alternative standard
levels characterized by uncertain estimates of health risk, a
choice calling for the exercise of judgment regarding how to
manage these predicted risks.'* This is dramatically

'° 62 Fed. Reg. 38677, 38679, PMJA 27, 29. The previous PMjo standard
controlled both coarse and fine PM. The court of appeals vacated the
coarse particle standard as arbitrary and capricious, see 175 F.3d at 1054-
55, App. 52a, because the PMyo indicator included a variable amount of
fine particulate matter. EPA has sought no further review of this ruling.

illustrated by EPA’s rulemaking addressing revision of the
ozone NAAQS.

Ozone is a constituent of smog produced by complex
chemical reactions in the atmosphere between volatile
organic compounds (“VOCs”) and nitrogen oxides (“NO,”)
emitted by numerous sources over broad areas. The reactions
that produce ozone take place over periods of days or longer,
through a process influenced by sunlight and other changing
atmospheric and meteorological conditions.

Further complicating ozone regulation, NO, and VOCs
that contribute to ozone formation are produced by natural as
well as human sources. As a result, short-term (e.g., 1-to-8
hour) ambient ozone concentrations average about 0.03 to
0.05 ppm even at remote and rural sites, such as Denali,
Glacier and Yellowstone National Parks, which are relatively
uninfluenced by mobile and stationary sources. The upper
range of short-term readings can exceed 0.07 ppm in such
remote areas.’

Promulgation of the 1-Hour Ozone NAAQS — The ozone
NAAQS that EPA revised in this rulemaking specified an
ozone concentration level of 0.12 ppm, based on a 1-hour
average, and allowed an average of one exceedance per year
over a three-year period. When EPA set this standard in
1979, it did so based on its judgment that “there is no clear
threshold... of adverse health effects,” and __ that

'° See EPA, Review of National Ambient Air Quality Standards for Ozone
20-21 (1996) [hereinafter OSP], OJA 1830-31; EPA, Responses to
Significant Comments on the 1996 Proposed Rule on the National Ambient
Air Quality Standards for Ozone 94, 96 (1997) [hereinafter ORTC], OJA
176, 178. See also 44 Fed. Reg. 8212, OJA 3490 (“Field measurements at
some remote sites, where man-caused ozone is likely to be negligible, have
shown low — but not insignificant — rates of exceedances of the 0.08 ppm
level.”).

“physiological responses probably occur in extremely
sensitive persons at very low levels.”'*

In 1993, EPA affirmed the appropriateness of this 1-hour
NAAQS to address a broad range of predicted and theoretical
health risks. In this 1993 decision, EPA was called upon to
exercise risk management judgment in making a decision that
promotes the “public health.”

For example, the Administrator found that revision of the
primary 1-hour NAAQS was not appropriate because changes
in performance on lung function tests after ozone exposures
at a 0.12 to 0.15 ppm level (e.g., temporary decreases in lung
capacity of 9-16% accompanied by respiratory symptoms)
“did not constitute adverse effects for purposes of section
109” even for “sensitive individuals,” and health studies
suggesting “aggravation of asthma and pre-existing
respiratory disease” at 0.12 ppm were limited by
“uncertainties about individual exposure levels and the role
of other pollutants.”'* In other words, the Administrator
found that not every predicted health risk or possible
physiological effect associated with exposure to ozone was a
potential adverse public health effect.

The Record for Revision of the Existing NAAQS -—-
Following this 1993 decision to reaffirm the existing 1-hour
NAAQS as “requisite to protect the public health” with an
“adequate margin of safety,” EPA in 1995 issued a revised
ozone criteria document. In evaluating the new criteria
document, the EPA staff explained that the public health

common feature of rulemaking and can lead to overly conservative or
“random” regulation. Breyer, supra note 12, at 42, 48.

11

consequences of ozone exposures at levels consistent with
the present 1-hour NAAQS remained highly ambiguous for
both “chronic” and “episodic” effects.’ Based on the revised
criteria document, the EPA staff concluded that there was an
“absence of discernible health effects thresholds and ... that
population risk [for respiratory symptoms, lung function
changes, and hospital admissions] varies little with small
changes in air quality.”’’ On this basis, the staff concluded
that a 0.09 ppm 8-hour standard (i.e., the 8-hour standard
level that EPA concluded was roughly equivalent to the 0.12
ppm 1|-hour NAAQS) “would reduce estimated exposures of
the at-risk population sufficiently to provide some margin of
safety.”"*

The staff concluded that the ranges of estimated risk were
little different for the existing 1-hour and alternative 8-hour
standards,’ and that these risk estimates did not even reflect
all of the uncertainties associated with the numerous
assumptions made to develop the estimates.” For example,

1865, 1871, 1963 (As the EPA staff observed, the database on ozone-
induced bronchial responsiveness is “limited and uncertain”; ozone’s
impact on urban asthmatic morbidity is “not well understood”; no
evidence was found that children exposed to low levels of ozone
experience respiratory symptoms; the evidence of permanent structural
changes in human lungs is “largely hypothetical”; and no association
between 6 to 8 hour ozone exposure and hospital admissions could be
assessed).

EPA’s January 1997 revised risk assessment showed that the
median risk of “large lung function decrements” would be
higher under an 8-hour standard than under the existing 1-
hour NAAQS in 2 of the 9 cities modeled, containing about
one-third of the sensitive population,”’ and that risks of
coughs and moderate lung function decrements (health
“endpoints” considered by EPA) for the l-hour NAAQS
would be /ower than the risks EPA found acceptable in
December 1996, when it proposed a 0.08 ppm 8-hour
NAAQS.” This EPA risk assessment also reported that risks
“are not dramatically different ... among the alternative 1-
hour and 8-hour standards” (including the existing 1-hour
NAAQS).”

EPA’s independent Clean Air Scientific Advisory
Committee (“CASAC”) reviewed the 1995 criteria document
and related staff analyses. These independent science
advisers concluded (1) that “our understanding of the health
effects of ozone is far from complete”; (2) that there are
“many gaps” in the science and “large uncertainties” in
EPA’s risk estimates; and (3) that “there is no ‘bright line’
which distinguishes any of the proposed standards (either the

Like the record for the ozone rulemaking, the record for
review of the PM NAAQS was characterized by uncertainty
about the magnitude and cause of any health risks. For
example, the EPA staff “emphasize{d] the unusually large
uncertainties associated with establishing standards for PM
relative to other single component pollutants for which
NAAQS have been set.””> CASAC members could form no
consensus regarding the level, averaging time, or form of a
revised standard because of the many unceriainties regarding
both the existence and nature of any causal relationship

concerns with the lack of air quality data and uncertainty
regarding the constituents of PM25 that should be regulated,
the President directed EPA to postpone implementation of the
revised PM); NAAQS until adequate air quality data were
collected and a further review of the standards was
completed.”’ Congress subsequently ratified that directive.”*

EPA's Decisions to Revise the NAAQS — EPA’s decisions
here were not driven by demonstrated health effects caused
by small exposures to the pollutants in question, but rather by
uncertain estimates of health risk. Reflecting these uncertain
risk estimates, the Administrator explained that her decisions
on revised NAAQS were the product of “policy” judgment.”’
According to the Administrator, these “policy” judgments
represented the degree of protection she declared was
“sufficient{]” in light of “[uJncertainties associated with
inconclusive scientific and technical information” and
“hazards that research has not yet identified.”*”

The Administrator explained that the level of public health
protection that she deemed sufficient for the revised NAAQS
was “largely judgmental in nature, particularly with respect to
non-threshold pollutants, and may not be amenable to
quantification in terms of what risk is ‘acceptable’ or any
other metric.”' In exercising this “judgment,” the
Administrator considered “the nature and severity” of
predicted health effects, “the size of the sensitive populations
at risk,” and the “kind and degree of uncertainties.”** Having
said this, the Administrator never explained how
consideration of these factors justified a change in the
management of predicted risks addressed by the then-current
standards, or how the revised standards would fulfill the

9a; see also id. 1034-35, App. 6a-7a (citing 62 Fed. Reg.
38883, OJA 28). To the contrary, according to the
Administrator, “nothing in the statute requires her to make
any specific ‘findings,”” even a finding of “significant risk.”””
In contrast to the uncertain and inconclusive nature of the
Administrator’s predictions of health risk, the records for
these rulemakings made quite clear that EPA’s standards
would have profound impacts on society, and might be
impossible to attain. According to the Administrator,
however, her judgment regarding standard revision could not
be informed by consideration of any information related to
their collateral health, social or economic consequences.**
For example, as part of its decision adopting the revised 8-
hour NAAQS, EPA promulgated a rule requiring the
development of a new, more stringent ozone reduction
program under Subpart | of the Act, in place of the program
that Congress had adopted when it enacted Subpart 2 in
1990.°° Because the new Subpart | program based on the

revised 8-hour NAAQS would “require significantly different

Congress established to address the same _ uncertain
predictions of health risk that EPA would now address
through a Subpart | program based on the revised 8-hour

”” Several of EPA’s science advisers recommended against having both |-
hour and 8-hour NAAQS because of the confusion it would cause for
achieving ozone reductions. See, e.g, CASAC Transcript of March 22,
1995, at 303, 308, OJA 280, 282 (remarks of James Price and George
Wolff). See also OSP, supra note 13, at 147, OJA 1957 (noting
“adequate reduction in risks” can be achieved with either a |-hour or 8-

17

In contrast to this successful NAAQS program,
implementation of the revised PMzs; NAAQS would be
impeded by a lack of air quality data and uncertainty as to
what constituents of PM; should be regulated to reduce
predicted health risks.“° Reflecting these problems, the
President and Congress postponed implementation of the
revised NAAQS until after the next five-year review cycle,
and until after a decision was made on “whether to revise or
maintain the new standards.”*"

Besides threatening to disrupt ongoing pollution
reductions under the existing NAAQS, the record showed
that, by EPA’s own admission, the costs of full attainment of
the revised ozone NAAQS (estimated by EPA at an
additional $9.6 billion per year over the existing NAAQS)
would outweigh its benefits (estimated by EPA at $1.5 to 8.5
billion per year)” EPA’s own estimates showed the cost of
attaining the revised particulate standards was extraordinarily
high, as much as $37 billion each year.”

The record also showed that these costs would reduce

EPA purportedly was exercising “policy” judgment to protect
the “public health.” Indeed, according to the Administrator,
even information showing that implementation of a revised
NAAQS will be “difficult, counter-productive or confusin
dofes] not undermine EPA’s [NAAQS] revision authority.”

Ill. THE D.C. CIRCUIT’S DECISION

Because the Agency had interpreted the Act to authorize it
to exercise judgment with no guiding principle, the court
below remanded the revised standards to EPA for further
rulemaking. According to the court, the Agency is obligated
to interpret the Act to provide an “intelligible principle” for
her exercise of risk management judgment. 175 F.3d 1034,
App. 5a.

The lower court also held that EPA must consider all
effects of an air pollutant in the ambient air — whether
adverse or beneficent — when selecting an appropriate
NAAQS. /d. 1052-53, App. 47a-48a. At the same time,
however, the court briefly and emphatically rejected the
suggestion that, in developing an intelligible principle to
guide its risk management judgment, the Agency may
consider factors such as indirect public health and
environmental impacts and costs, factors that any rational

radiation. EPA did not petition this Court for review of that aspect of the
lower court’s decision.

person would consider relevant to determining the acceptable
level of public health risk.”

Quoting earlier decisions of the circuit, the court
concluded that this issue was resolved “in Chevron step one
terms,” because the CAA “on its face does not allow
consideration of technological or economic feasibility.” /d
1040, App. 19a. According to the court, this prohibition on
the factors the Administrator may consider in exercising
“public health” risk management judgment extends not only
to the costs and feasibility of control technologies, but to all
the indirect health, environmental and economic impacts that
might be caused by a decision to revise an existing NAAQS.

Although the court below made minor modifications to its
opinion on rehearing, 195 F.3d 10, App. 79a-80a, it did not
change its holding limiting the factors EPA can consider in
managing public health risk.

SUMMARY OF ARGUMENT

Section 109 of the Clean Air Act directs the EPA
Administrator to set NAAQS that are “requisite to protect the
public health” with an “adequate margin of safety,” and to
make such revisions to those standards as may be
“appropriate in accordance with [§§ 108 and 109(b)].” Such
standards must be supported by a sound scientific record. In
revising the NAAQS for ozone and PM, the Administrator
relied on uncertain predictions of health risk to adopt revised
standards that will set in motion two of the most costly and

* 175 F.3d at 1040, App. 18a-20a. The only example the court gave of
how EPA could develop a “principled structure” for setting NAAQS,
however, was Oregon’s Medicaid program, a program that relied on cost
considerations. /d. 1039, App. 15a-18a.

22

burdensome regulatory programs ever required by a federal
administrative agency.

Citing uncertain “risk” estimates and reflecting the
assumed lack of any level of exposure at which there is an
absence of health risk, the Administrator’s decisions to revise
the NAAQS were “largely judgmental in nature... and may
not be amenable to quantification in terms of what risk is
‘acceptable’ or any other metric.” 62 Fed. Reg. 38883, OJA
28 (emphasis added); id. 38688, PMJA 38 (emphasis added).
The costs of these standards, however, can be measured both
in the potential for adverse impacts on public health and the
environment, and in the dollars required to attain them (up to
$150 billion each year). EPA concedes that the revised
ozone NAAQS have costs that may exceed their benefits, and
that NAAQS will interfere with a separate congressional
program for reducing ozone to address the health risks at
issue here.

In revising these NAAQS, the Administrator concluded
that she was precluded from considering the indirect health,
environmental and economic effects of her policy decision to
provide additional margin of safety in response to uncertain
health risk — factors that would normally be relevant to sound
“public health” policy judgment. The United States Court of
Appeals for the District of Columbia Circuit agreed that the
Administrator had no authority to consider such factors,
relying on its own precedents with Lead IJndustries
Association v. EPA, 647 F.2d 1130 (D.C. Cir. 1980). This
decision should be reversed.

1. Broad delegations of regulatory authority must be
implemented to give effect to congressional purpose, absent
statutory language directing a different result. In the Clean
Air Act, Congress specified through explicit statutory
language that the goal of the Act is to promote the “public

23

health” which, by its very definition, includes consideration
of economic and social realities. The language of § 101(b)(1)
of the Act, according to EPA itself, calls for a “balancing of
the social and economic considerations with the
environmental implications” of a regulatory decision. 39
Fed. Reg. 31000. This Court’s precedents have long
recognized that the normal meaning of statutory terms as well
as the statutory purposes must be used to provide decisional
criteria where statutory terms are undefined, unless there is
clear statutory evidence requiring a different result. There is
no such evidence here.

2. Section 109(b)(1) of the Clean Air Act, directs the
Administrator to establish standards at a level “requisite” to
protect the “public health” with an “adequate margin of
safety.” When confronted with predicted but uncertain health
risk, as opposed to a demonstrated “adverse effect” on public
health, these terms call for the exercise of risk management
judgment that involves balancing a broad range of factors
consistent with the statutory purposes section of the Act.

a. None of this statutory language directs the
Administrator, in exercising this risk management judgment,
to ignore factors such as the total health, environmental, and
economic @onsequences of actions that are critical to
protecting and promoting the public health. Indeed,
consideration of these factors is consistent with the common
understanding of “public health” regulation, which
contemplates a balancing of factors to improve the conditions
wm which people live. Consideration of these factors also is
essential to fulfilling the Clean Air Act’s overriding statutory
purpose of protecting the public’s health in a way that also
promotes the “public welfare” and the “productive capacity”
of the people of this country. Finally, the common approach
to establishing am “adequate margin of safety” requires

24

considering both the costs and the benefits of the margin in
question.

b. Furthermore, § 109(d)(1) of the Act directs
EPA to revise NAAQS “as may be appropriate in accordance
with” §§ 108 and 109(b). Those sections then tell the
Administrator, as part of this standard revision process, to
obtain from her science advisors information on the overall
impacts on society of standard revisions. This is consistent
with congressional intent that the Agency exercise its
judgment to manage public health risk in a manner that
promotes the statutory purposes.

c. The Act’s legislative history confirms that
Congress expected the Administrator to consider practical
impacts including societal costs to determine whether the risk
posed by a pollutant such as ozone or PM is unacceptable or
whether standard revisions were “appropriate.” Congress
understood that NAAQS were not intended to be standards
which eliminate any and all health risk. Rather, Congress
observed in 1970 when it enacted §§ 108 and 109, and again
in 1977 when it amended §§ 108 and 109, that these
provisions do not contemplate “zero risk” regulation, but
rather a “reasonable degree of protection.”

3. Finally, review of the language, structure and
purposes of the Act shows that the circuit precedent on which
the lower court relied — Lead Industries — was wrongly
decided. There is no statutory language providing, as the
Lead Industries court concluded, that costs and other impacts
may “play no part in the promulgation of [NAAQS].” 647
F.2d at 1148. Rather, applying this Court’s subsequent
decision in Chevron, this Court should conclude that,
consistent with the congressional purposes stated in § 101(b)
of the Act, the statute on its face contemplates consideration

25

by EPA of the broad impacts on society of its NAAQS
decisions when it manages health risks under § 109.

ARGUMENT

The standards before the court are standards that protect
against predicted “risk” from pollution, not against pollution
that has been shown to cause an adverse public health
“effect” like the London “killer fog.”** Under the Act,
NAAQS must be set below the level at which such
demonstrated adverse public health effects occur. This case,
by contrast, involves pollution levels far below those at
which adverse public health effects have been demonstrated.
What is at issue here is how EPA manages health “risks.”

In making decisions to manage risks (as opposed to
eliminating known, adverse public health effects), EPA must
act like any other agency with “public health” risk
management responsibilities. A mandate to protect the
“public health” does not contemplate elimination of all health
risk, or absolute protection of any particular individual.*°

** Historically, increased mortality and morbidity has been observed
during episodes of extremely high levels of air pollution PMSP, supra
note 11, at V-11, PMJA 1962. With fine particles, for example, such
effects have been observed with levels reaching 500-1000 yg/m’ or more
daily. 61 Fed. Reg. 65641-42 & n.7, PMJA 122-23. This is at least an
order of magnitude higher than daily fine PM levels observed today in
this country. See PMSP, supra note 11, at IV-17a, PMJA 1943. By
contrast, the studies on which the new standards are based used statistical
techniques to predict the possibility that health effects might occur at
ambient concentrations extending down to background levels.

Indeed, EPA agrees that not every predicted “health risk” is a
“public health” risk.

Rather, as traditionally understood by public health
professionals, “many factors such as the social, economic and
physical environment in which the people live” can affect the
public’s health.°’ Regulation that addresses public health
risk therefore “operates in a world of choices in the allocation
of limited resources,” and contemplates a focus on

“fulfill[ing] society’s interest in assuring conditions in which
people can be healthy.”*”

As such, “public health, as both a goal and a practice, is as
inherently political (i.e., concerned with the allocation of
resources in society) as it is technological (i.e., concerned
with deployment of professional knowledge of illness).”™
Developing public health policy necessarily involves
tradeoffs in order to choose the risk management option that
produces th greatest value for society.

In this case, citing a flawed interpretation of the CAA in
the lower court’s 1980 Lead Industries decision, the D.C.
Circuit held that Congress prohibited the EPA from
considering factors that are necessary to sound public health
risk management judgment in setting or revising NAAQS.
For the following reasons, this result is neither consistent
with the Act nor logical, and may result in decisions that do
not promote the public health.

I. THE STATUTORY PURPOSES MUST INFORM
AN AGENCY’S IMPLEMENTATION OF A
BROAD CONGRESSIONAL DELEGATION.

Broad delegations of congressional authority must be
implemented in a manner consistent with the ordinary
meaning of undefined statutory terms,°! and in a manner that
furthers Congress’ overall purposes in enacting the
legislation. As the Court only recently explained, “in the
absence of a statutory definition,” courts should look to “both

the generally accepted meaning of the term and to the

28

purpose of the statute.” Furthermore, a court’s “obligation
is to give effect to congressional purpose so long as the
congressional language does not bar that result.”

Thus, where Congress has not provided detailed guidance
for implementation of a statutory provision, this Court has
analyzed the validity of an agency’s regulation by examining
its conformance with the “fundamental objective” of the
statute in question.” Only last term, in striking down a
regulatory program adopted by the FCC, this Court
emphasized that broad delegation of regulatory authority
requires the agency “to apply some limiting standard
rationally related to the goals of the Act.”** Indeed, the
failure to apply any limiting standard related to the goals of
the Act may raise concerns under the congressional
nondelegation doctrine.”

As early as 1967, in enacting the first Air Quality Act,
Pub. L. No. 90-148, 81 Stat. 485, Congress explained that the
development of air quality standards should “be influenced

not only by a concern for the protection of health or welfare,
but also by economic, social and _ technological
considerations.””’ In amending the Act in 1977, Congress
again emphasized that the Act’s purpose was to “insure the
protection of the public health and the environment ... while
at the same time considering the energy and economic needs
of this Nation.”

Reflecting these principles, Congress has long recognized,
in explicit statutory language, that the fundamental objective
of the Act is to promote the “public health” consistent with
economic and social realities. Thus, Congress stated in
§ 101(b) of the Act that the purpose of the Act is “to protect
and enhance the quality of the Nation’s air resources so as to
promote the public health and welfare and the productive
capacity of its population.” CAA § 101(b)(1) (emphasis
added).

The Agency itself has explained the importance of
exercising its discretion in light of the Act’s stated goal “to
protect and enhance the quality of the nation’s air resources
so as to promote the public health and welfare and the
productive capacity of its population.” As EPA has
observed, this language contemplates “a balancing of the
social and economic considerations with the environmental

implications” of a decision in order “to fulfill the mandate”
of the Act.”°

Framing EPA’s responsibilities to accommodate these
statutory objectives does not call for the Administrator to
ignore the broad impacts on the public of alternative
approaches. Rather, it calls for balancing to ensure that the
Agency’s judgments reflect sound public health policy.

These statutory purposes have special relevance in the
context of a regulatory program calling on the Agency to
exercise “public health” risk management judgment, a term
which by its very definition contemplates sonsideration of the
social and economic realities of an age: -y's risk management
decision. Thus, for example, regulation that trades reduction
in some predicted health risks for increases in others may not
further the “public health.” Similarly, adopting a revised
NAAQS that makes implementation of an air quality standard
“difficult, counterproductive or confusing”’' may not
promote the “public health.” Anc imcreasing the costs of
regulation to society in an attempt to insure against
speculative risk may in fact impair, sot protect, the “public
health.”

overriding importance of the purposes section of the Clean Air Act by
ruling that section 101(b)(1) imposed upon the Administrator the
obligation to establish a regulatory program that was not mentioned in the
operative provisions of the Act. See Sierra Club y EPA, 540 F.2d 1114

A profligate commitment of money and technology to
guard against one set of uncertain health risks may result in
inadequate means to cope with other more serious
problems.” Indeed, without consideration of the unavoidable
relationship between the costs of goods produced and the
capacity of the public to purchase such goods, stringent
margins of safety designed to protect against hypothetical
risks that by their nature are uncertain could have the effect
of increasing the cost of — and perhaps even denying to the
poor and those on fixed incomes — products such as
electricity for heating and cooling that are essential to the
public’s health. As Justice Powell recognized in his
concurrence in Union Electric Co. v. EPA, for example, the
“shutdown of an urban area’s electrical service could have an
even more serious impact on the health of the public than that
created by a decline in ambient air quality.” 427 U.S. 246,
272 (1976).

In this case, EPA must construe the Act to apply “some
limiting standard, rationally related to the goals of the Act””*
to govern its exercise of public health risk judgment, unless

this Court finds that Congress explicitly directed EPA to
ignore the statutory language defining the purposes of the
Act. Because, as discussed below, there is no such explicit
constraint on the Agency’s regulatory authority in § 109 of
the Act, the Agency must look to the concept of “public
health” as commonly understood by health professionals and
to the purposes section of the Act in formulating decisional

criteria to govern management of uncertain health risks under
CAA § 109.

Il. CONGRESS IN §109 CONTEMPLATED THAT
EPA WOULD CONSIDER THE BROAD IMPACTS
ON SOCIETY OF ITS PUBLIC HEALTH RISK
MANAGEMENT DECISIONS CONSISTENT
WITH THE PURPOSES OF THE ACT.

No one disputes that the NAAQS program has truly
extraordinary impacts on the Nation’s economy and on
society generally. EPA’s own analyses show that the revised
standards at issue represent perhaps the most costly
regulatory decision ever made by that agency.”° In addition
to these very high implementation and control costs, the types
of impacts include adverse health impacts associated with
increased UVB radiation exposure; increased unemployment;
the higher cost of essential products; disruption in the
implementation of the congressional ozone reduction
program; and disruption of highway safety programs. See
supra pp. 15-18. Furthermore, EPA has explained that the

revised NAAQS may simply be impossible to achieve in
some areas.

These, of course, are the types of concerns that led
Congress in 1990 to amend the Act to establish the Subpart 2
program for managing the uncertain public health risks
addressed by the 1l-hour ozone NAAQS.”’ And concerns
about implementation and efficacy of the revised standards
also caused Congress to delay implementation of the revised
PM25 NAAQS.

The lower court has held that EPA has no statutory
authority to consider any of these impacts when exercising
public health risk management judgment under § 109. But
there is nothing on the face of either §§ 108 and 109 that
prohibits the Administrator from balancing the broad range of
factors called for in § 101(b)(1) of the Act in exercising her
risk management judgment. To the contrary, the language of
§§ 108 and 109 supports the use of the statutory purposes to
derive decisional criteria for the Administrator’s exercise of
risk management judgment.

A. Sections 108 and 10%(b) Do Not Mandate
Uninformed Public Health Risk Management
Decisions.

Under § 109, NAAQS are to be set at a level that, in the
“judgment” of the Administrator, is “requisite to protect
public health” allowing an “adequate” margin of safety.
Nothing in this language tells the Administrator to exercise

her risk management judgment with blinders to the broad
consequences for society of her decisions.

The plain meaning of the word “requisite” is
“indispensable” or “necessary,” suggesting that the
Administrator must establish a need for the revised standard
to protect public health.” Furthermore, as discussed above,
the concept of “public health” calls on regulators to promote
the overall health of the population by reducing predicted
risks to acceptable levels. See supra pp. 24-27.

Whether a standard is “requisite” to protect the “public
health” in the face of uncertain predictions of health risk,
therefore, does not on its face limit the factors relevant to the
Agency’s exercise of risk management judgment. To the
contrary, a standard cannot be “requisite” to protect the
“public health” without some understanding of whether and
why predicted health risks are unacceptable under the
existing standard, and yet acceptable under the revised
standard.*'

As this Court has “frequently reiterated..., an agency must
cogently explain why it has exercised its discretion in a given
manner.” But, to use the ozone case as an example, where
there is no “bright line” distinguishing alternative standards
from a public health protection standpoint, see supra pp. 12-
13, how can the alternative that imposes the greatest overall
burdens on society be “requisite” to protect the public’s
health? How can a standard that imposes enormous costs on
society and that cannot be achieved in many areas, see supra
pp. 15-16, be “requisite” to protect the public’s health as
compared to a standard that imposes fewer burdens and is
being successfully implemented to reduce the same “public
health” risks? The Agency never answers these questions on
the grounds that Congress told it not to — an illogical and
implausible result under a statute whose purpose is to
promote the public health and welfare and the productive
capacity of the country’s population. CAA § 101(b)(1).

Similarly, the statutory direction that the Administrator
select a margin of safety that is “adequate” does not suggest
that she ignore the broad impacts of her decision on society
when exercising risk management judgment. To the
contrary, as the en banc D.C. Circuit observed in addressing
the similar language of CAA § 112, a finding that a level of

air quality is “safe” does not require that it be “risk free.”
Furthermore, even a requirement to provide an “ample”
margin of safety to protect public health does “nor ...
preclude consideration of any factor.”™*

The “adequaicy]” of a margin of safety cannot be
determined in the abstract. Like purchasing insurance to
protect against the possibility that a risk will become a
reality, how much margin is “adequate” will depend on a
broad range of factors including the certainty, size and nature
of the risk, and on the cost of providing that insurance (or
“margin” of safety) to protect against that predicted risk.*°

If insurance can be provided at little cost, it may be worth
the price. If insurance is so costly that it would impoverish
those to be protected, it should be rejected as doing “more
harm than good.””* Similarly, in the case of a non-threshold
pollutant where some health risk is assumed at any level
above “zero,” what margin of safety is “adequate” can be
informed only by striking the balance contemplated by the
purposes section of the Act.

Congress in 1977 also adopted a “significant risk”
standard as the threshold for regulation under the NAAQS

program. A numer of commentators have explained that
the significance of risk cannot be determined in isolation
from the costs of eliminating that risk.™

In short, determining whether an existing NAAQS —
provides an “adequate” margin of safety, or whether a revised
NAAQS is “requisite” to protect the “public health,” are
quintessential risk management judgments that require a
baiancing of all factors relevant to promoting the public’s
health. This authorizing language does not call on the
Administrator fo ignore the consequences of her decisions;
rather, she can promote the public health only by considering
those consequences and striking the balance contemplated by
§ 101(b) of the Act.

This conclusion finds additional support in the language of
§ 108 describing the information that must be available for
NAAQS decisions. For example, § 108(a) provides that the
criteria document that is considered in making NAAQS

decisions is to address “all identifiable effects on public
health or welfare expected from the presence of such
pollutant in the ambient air, in varying quantities,” as well as
“variable factors (including atmospheric conditions) which of
themselves or in combination with other factors may alter the
effects [of the pollutant] on public health or welfare.’ A
range of health risks might flow from the presence of a
pollutant in the ambient air, including both direct effects
associated with exposures to the pollutant (e.g., inhalation
health risks) and indirect health effects associated with how
programs for reducing the pollutant as it is present “in the
ambient air” are affected by NAAQS revision.

In other words, a standard that cannot be achieved, or that
will render pollutant reduction efforts more “difficult,
counter-productive, or confusing,” Brief of Respondent EPA,
at 73 (D.C. Cir. No. 97-1441), as compared to available
alternatives, has identifiable and adverse impacts on public
health. “[Ajll identifiable effects” of the pollutant as
influenced by such real world factors are appropriate topics
for consideration in the criteria document and by EPA during
the NAAQS rulemaking. Indeed, in a portion of its decision
not challenged by EPA, the lower court rejected EPA’s
refusal to construe the “all identifiable effects” language to
include the UVB radiation effects of ozone reduction. 175
F.3d at 1051-52, App. 43a-46a. Clearly, this language is not
limited to inhalation-related effects, as EPA has construed it.

Section 108 also directs EPA to address in its criteria “all
identifiable effects” on “public ... welfare,” CAA
§ 108(a)(2), a term that includes “economic values.” CAA
§ 302(h). EPA must also provide “simultaneously” with
issuance of the criteria document information on the “cost ...

39

energy requirements, emission reduction benefit, and
environmental impact” of alternative control strategies. CAA
§ 108(b)(1). In view of this statutory language, EPA is
required to have available to it for any NAAQS rulemaking
all of the information it needs to exercise sound risk
management judgment. That Congress directed EPA to
develop this information under §108 in time for
consideration in NAAQS rulemakings does not mean that
EPA must ignore it, but rather supports the conclusion that
EPA should exercise its risk management judgment in light
of this information and consistent with the statutory purposes
of the Act.

In sum, Congress in §§ 108 and 109 did not tell EPA to
exercise public health risk management judgment by ignoring
the overall consequences of its action. Rather, Congress’
broad delegation of risk management authority must be
implemented by defining limiting standards that protect the
“public health” while promoting the statutory purposes of the
Act.

B. Section 109(d) Confirms The Need For
Consideration of the Impacts on Society of
Decisions on Whether to Revise NAAQS.

Once EPA has established a NAAQS for a pollutant, as it
has for both pollutants in this case, Congress directed that
EPA revise the standard periodically as “may be appropriate”
in accordance with §§ 108 and 109(b). CAA § 109(d)(1). In
the case of standard revision, there is by definition a standard
in place that the Agency previously determined was
“requisite to protect public health” with an “adequate margin
of safety.”

To establish that standard revision is “appropriate” in
accordance with §§ 108 and 109(b), the Agency must explain

40

why a change in the status quo is “requisite” to protect
“public health.” In other words, the agency must explain why
the existing standard is no longer “appropriate” in accordance
with §§ 108 and 109(b) and the revised standard is.

This analysis by definition recognizes the need to evaluate
a broad range of relevant factors. See West v. Gibson, 527
U.S. 212, 218 (1998) (“The meaning of the word
‘appropriate’ permits its scope to expand” as changes in the
law, or in the world, would require). In other words, the
“appropriate” language confirms the importance of the
ordinary meaning of “public health” and the statutory
purposes as a source of decisional criteria for the Agency’s
exercise of discretion regarding NAAQS revision.

Furthermore, as discussed above, the broad language of
§ 109(b) contemplates the exercise of risk management
judgment, and the information requirements of § 108 ensure
that the Administrator will have at her disposal all of the
information required for reasoned “public health” risk
management. In the context of standard revision, § 109(d)
specifically directs the Administrator to make any
“appropriate” revisions “in accordance with § 108” — a
provision that requires (under § 108(b)) development of
information on implementation impacts “simultaneously”
with public health information.

Whether standard revision is “appropriate in accordance
with” § 108 and § 109(b) therefore does not limit the factors
relevant to the exercise of risk management judgment.
Rather, it contemplates the balancing of a range of factors
consistent with the purposes of the Act.

In exercising her standard revision authority, Congress
also required the Administrator to obtain the advice of her
science advisers on a number of factors, including areas
where additional knowledge is needed to understand the

41

adequacy of existing and revised NAAQS, and on the “public
health, welfare, social, economic, or energy effects which
may result” from alternative implementation programs.”
CAA § 109(d)(2)(C){iv).

Some of this information goes to the evaluation of the
direct health risks of alternative air quality levels and
implementation approaches. Other information goes to the
risk management judgment on whether standard revision is
“requisite” to protect public health, on whether margins of
safety under existing and revised standards are “adequate,”
and on whether existing standards should be revised at all in
light of “areas in which additional knowledge is required to
appraise the adequacy” of existing standards. CAA
§ 109(d)(2)(C)(i).

The Administrator does not dispute that certain of the
information her science advisers must develop (e.g.,
information on the “adequacy” and “basis” of existing and
revised standards) is relevant to her decision on standard
revision. She has asserted, however, that other information
that must be developed (e.g., impacts resulting from
alternative attainment strategies) is irrelevant to revising the
standard.

The statute on its face does not direct the Administrator to
consider only some of these § 109(d) factors and not others in
determining what approach to managing uncertain health risk
is “appropriate” in accordance with the “adequate” margin of
safety and the “requisite” to protect “public health” language
of § 109(b). Indeed, it would be unreasonable to conclude

(D.C. Cir. 1973) (heightened standard of explanation required to override
science advisor’s advice).

that Congress wanted EPA to have all of this information
before it, but to consider only some of it.”!

Congress, of course, commented in legislative history that
the type of information identified in § 109(d) may be “of
interest and assistance to the States and Congress.””
Nevertheless, Congress directed CASAC in the statute “to
advise the Administrator with respect to any harmful effects”
of standard revision in the context of her consideration of
standard revision. CAA § 109(d)(2)(C)(i) (emphasis added).

As this Court has recognized, an agency has a heightened
burden to explain its decision to change an existing
regulatory program.’ In this case, where existing air quality
standards were in place that EPA had previously determined
were “requisite to protect the public health” with an
“adequate margin of safety,” CAA § 109(b)(1), the Agency
cannot fulfill its obligation of reasoned decisionmaking by
ignoring information that Congress told it to develop.

C. The Legislative History Confirms the Need For
Balancing to Promote the Purposes of the Act.

The legislative history confirms the message of the
statutory language that Congress intended the Agency to
exercise sound public health risk management judgment in
light of the purposes of the Act and the commonly
understood meaning of “public health.”

In enacting the NAAQS program in 1970, the Senate
explained that the “primary” NAAQS were to set a “national
health minimum” standard which would provide a
“reasonable degree of protection.” See S. Rep. No. 91-1196,
at 10, reprinted in 1 1970 Legis. His:., supra note 7, at 410,
OJA 3687. With this understanding, Congress left States the
option to establish an ambient air quality standard “more
stringent” than the “national health minimum.” /d.

In 1977, when it amended the Act, Congress understood
that the NAAQS did not incorporate a “no risk philosophy”
and explained that NAAQS should reflect the principle that
“public [health] policy ... [be] wise policy.”* Further
reflecting Congress’ delegation of authority to EPA to
manage (not eliminate) health risk to achieve the Act’s
“public” health objective, Congress established in 1977 an
additional CAA prograin to prevent significant deterioration
(PSD) of air quality in areas where air quality is better than
the NAAQS.

™ See H.R. Rep. No. 95-294, at 127, reprinted in 4 1977 Legis. Hist.,
supra note 8, at 2594, OJA 3678; Hearings on S. 251, S. 252 and S. 253
Before the Subcomm. on Environmental Pollution of the Sen. Comm. on
Env't and Pub. Works, 95th Cong., Ist Sess., at 6-7 (1977) (Chmn.
Muskie); see also id. at 37.

* See CAA Title I, Part C, §§ 160-169.

44
In arguing for this “non-degradation” program, Senator
Muskie, the Clean Air Act’s chief sponsor, explained that

were set for dirty air areas as the minimum
necessary and the minimum reasonably
attainable in the dirty area areas.... Even at
the national primary standard level, which is
the health standard, there are health effects
that are not protected against.... At any level
between zero pollution and the pollution
permitted by national U primary standards,
there are health effects.

This PSD program is intended to address “any actual or
potential adverse effect,” CAA § 160(1) (emphasis added),
thereby addressing health risks not addressed by the “public
health” standards established under § 109. In other words,
Congress in 1977 recognized that not all predicted health
risks are public health risks, and Congress therefore
responded with a separate program to address those health
and welfare risks at levels of air pollution lower than
specified by the NAAQS. Given this statutory matrix,
Congress could not have intended that EPA ignore all of the
costs and practical impacts of the risk management
judgments required in setting the public health-based
NAAQS.

In 1990, Congress enacted extensive amendments to the
Clean Air Act, but did not amend the NAAQS program in
§§ 108 and 109. Thus, Congress left in place a program that
delegates to EPA authority to exercise public health risk

* See 123 Cong. Rec. 18460, reprinted in 3 1977 Legis. Hist., supra note
8, at 1030 (emphasis added), OJA 3669.

45
management judgment in setting and revising NAAQS.
Implicit in that delegation is the obligation for the Agency to
“give clear indication that it has exercised the discretion with
which Congress has empowered it.””’ Far from directing the
Agency to ignore factors that are relevant to the exercise of
reasoned risk management judgment, the legislative history
of the 1970 Act and the 1977 Amendments to § 109 confirms
that this discretion must be exercised in a manner that
furthers the statutory purposes of the Act.
* > * J

As the Court has said, judges “must be guided to a degree
by common sense as to the manner in which Congress is
likely to delegate a policy decision of such economic and
political magnitude to an administrative agency.” In this
case, there is nothing on the face of the Act that directs the
Administrator, in exercising her judgment to determine
whether a standard revision is appropriate, to ignore the
broad impacts of her decision on society. To the contrary, the
common understanding of “public health” regulation and the
explicit statutory language in § 101(b)(1) of the Act requires
the Agency to strike a balance considering all factors.

lll. LEAD INDUSTRIES, WHICH THE LOWER

COURT CITES AS THE BASIS FOR ITS
DECISION, SHOULD BE OVERRULED.

Without parsing the language of the statute or even
mentioning the purposes section of the Act, the lower court
has simply relied on Lead Industries, and subsequent cases

” Phelps Dodge Corp. v. NLRB, 313 U.S. 177, 197 (1941).

” FDA v. Brown & Williamson Tobacco Corp., 120 S.Ct. 1291, 1301
(2000).

46

citing Lead Industries,” for the proposition that the
Administrator is precluded from considering the broad
impacts of her decision on society in exercising her public
health risk management responsibilities. 175 F.3d at 1040-
41, App. 19a-2la. According to the court, this is a simple
matter of statutory construction that can be resolved under
“step one” of Chevron. See id. at 1040 (explaining that Lead
Industries was decided “in Chevron step one terms”’).

The Lead Industries case, however, was decided before
Chevron and found clarity of congressional expression in
§ 109 where none exists. Indeed, as discussed above, a
Chevron “step one” analysis of all of the relevant Clean Air
Act provisions, including the purposes section of the Act,
confirms that EPA has broad discretion to consider and to
balance all relevant factors in making “public health” risk
management decisions. Because Lead Industries as applied
by the lower court is at odds with the statute, it should be
overruled.

First, as discussed above, nothing on the face of the statute
directs EPA in exercising risk management judgment to
ignore the broad impacts of its decision on society. In fact, as
the D.C. Circuit observed in Lead Industries, “[s}ection
109(b) does not specify precisely what Congress had in mind
when it directed the Administrator to prescribe air quality
standards that are ‘requisite to protect the public health.””
647 F.2d at 1152.

Where Congress has delegated in broad terms, it is for the
agency to fill out the statutory provision “within the limits of
[the congressional] delegation.”'” Reflecting this
established principle, the D.C. Circuit has repeatedly held in

” American Petroleum Inst., 665 F.2d at 1148; NRDC, 902 F.2d at 973.
'° Chevron, 467 U.S. at 865; see also Smiley, 517 U.S. at 740-41.

47

the wake of this Court’s decision in Chevron that an agency
is free to consider costs when not expressly precluded from
doing so by statute.""' Indeed, as discussed above, a
determination that regulation is “requisite” to protect the
“public health” with an “adequate” margin of safety in
response to predicted and theoretical health risk cannot be
made without considering the overall impacts of the decision
on society, including the costs of that decision.

Second, while the Lead Industries court asserted that the
structure of the Act and legislative history supported its broad
statement that costs can play no role in the promulgation of
air quality standards, just the opposite conclusion is more
appropriate in cases where the Agency must exercise risk
management judgment to address uncertain and predicted
health risk. In this case, Congress explained that the NAAQS
program does not contemplate “zero risk” regulation.
Congress therefore called on EPA to exercise judgment as to
what risk is acceptable, in setting standards that are
“requisite” to protect the “public health” with an “adequate”
margin of safety. That judgment cannot be exercised without
an understanding of the overall consequences of the Agency’s
action.

Third, the Lead Industries court reasoned that the
“technology-forcing” nature of the CAA supports the
conclusion that Congress wanted EPA to ignore the costs and
feasibility of control technologies in setting NAAQS. 647

'*" See, e.g., Michigan v. EPA, No. 98-1497, 2000 WL 180650, at *12
(D.C. Cir. Mar. 3, 2000) (“{Ojnly where there is a ‘clear congressional
intent to preclude consideration of costs’ ... [do] we find agencies barred
from considering costs.”); see also, e.g, Vinyl Chloride, 824 F.2d at
1155; George E. Warren Corp. v. EPA, 159 F.3d 616, 622-23 (D.C. Cir.

1998); Grand Canyon Tour Coalition v. FAA, 154 F.3d 455, 475 (D.C.
Cir. 1998).

48

F.2d at 1149. However, this has little relevance to the
exercise of public health risk management judgment. In
other words, NAAQS that are set to reflect sound risk
management principles will still require industrial sources to
install whatever controls it takes to achieve those NAAQS.
Similarly, while the D.C. Circuit has pointed to congressional
statements that sources would have to shut down if they
could not meet the NAAQS as supporting its construction of
§ 109, see Vinyl Chloride, 824 F.2d at 1159, sources would
still have to shut down if they could not meet a NAAQS that
reflects the exercise of sound public health risk management
judgment.

Finally, Congress did not re-enact § 109 of the Clean Air
Act in 1990, nor did it amend § 109 to codify the lower
court’s interpretations of § 109. No changes were made to
§ 109 in 1990. As a result, isolated statements in the 1990
legislative history (which EPA has argued suggest
acquiescence to the D.C. Circuit’s earlier decisions'™) should
be treated with great skepticism. As this Court has
commented, “the views of a subsequent Congress form a
hazardous basis for inferring the intent of an earlier one.”'”
Indeed, where Congress has not been requested to act on a
statutory provision, and has taken no action, there is no basis

'? Brief for the Federal Cross-Respondents in Opposition, at 14-15 (Nos.
99-1426, 99-1431, 99-1442).

Central Bank, N.A. v. First Interstate Bank, N.A., 511 U.S. 164, 185-87
(1994) (rejecting application of the “acquiescence doctrine” where
Congress had amended other statutory provisions within the Act).

49

for concluding that Congress as a legislative body had any
intent on the matter.'™

In sum, when EPA regulates pollutant concentrations that
are below any known “adverse effects” threshold, there will
always be ranges of theoretical and uncertain predictions of
health risk. The Agency must examine this range and decide
whether standard revision is “appropriate” and will promote
the overall goals of the Act.

Congress’ delegation to EPA of authority to choose a
result that is “appropriate” does not forbid consideration of
any factor relevant to managing public health risks in a way
that promotes the purposes of the Act. Therefore, a judicial
interpretation of § 109 that precludes consideration of
societal costs and related factors must be rejected under any
sound Chevron “step one” analysis It is now time to resolve
the confusion that has been created by Lead Industries by
overturning that decision as inconsistent with the Act and the
principles enunciated by this Court in Chevron.

CONCLUSION

For the reasons stated above, the decision of the lower
court that EPA is precluded from considering the broad
impacts of its decision on society in exercising risk
management judgment under § 109 should be reversed,

'* See Central Bank N.A., 511 U.S. at 185-87; id. at 186 (citing U.S.
CONST. art. I, § 7, cl. 2). See also Immigration and Naturalization Serv.
v. Chadha, 462 U.S. 919, 954 (1983) (“Amendment and repeal of
statutes, no less than enforcement, must conform with Article !.”).

and the standards should be vacated because they were not
based on consideration of all relevant factors.
