QUESTIONS PRESENTED

Sections 108 and 109 of the Clean Air Act, 42 U.S.C.
§§7408-7409, direct the Administrator of the Environmental
Protection Agency (“EPA”) to set and periodically revise
national ambient air quality standards (“NAAQS”) for a limited
subset of air pollutants, based on the latest scientific evidence
concerning the nature and magnitude of the effects of these
pollutants on public health and welfare. Sections 181 and 182
of the Act, 42 U.S.C. §§ 7511-7511f, impose specific deadlines
and requirements on those portions of the nation not in
_ compliance with the ozone NAAQS in effect when Congress
added these provisions to the Act. The questions presented are
as follows:

1. Whether the EPA Administrator’s 1997 promulgation of
revised NAAQS for particulate matter and ozone rested on an
application of Clean Air Act sections 108 and 109 that amounts
to an unconstitutional delegation of legislative authority to the
executive in violation of Art. I, § 1 of the Constitution.

2. Whether sections i81 and 182 of the Clean Air Act
permit the Administrator to promulgate a revised ozone
NAAQS but forbid her to enforce the revised standard.

PETITION FOR A WRIT OF CERTIORARI

Petitioners respectfully petition for a writ of certiorari to
review the judgment of the United States Court of Appeals for
the District of Columbia Circuit in this case.

OPINIONS BELOW

The opinion of the court of appeals (App. 1-63) is reported at
175 F.3d 1027. The following orders of the court of appeals are
reported at 195 F.3d 4: the order granting in part and denying in
part petitioners’ petition for rehearing (App. 64-82); the order
denying, by a vote of 4-5 of the judges participating, EPA’s
petition for rehearing en banc (App. 83-91); and the order
denying petitioners’ petition for rehearing en banc (App. 92-93).

JURISDICTION

The judgment of the court of appeals was entered on May 14,
1999. On October 29, 1999, petitioners’ timely petition for
rehearing was granted in part and denied in part; petitioners’
timely petition for rehearing en banc was denied; and the court
denied, by a 4-5 vote of the judges participating in the decision,
EPA’s timely petition for rehearing en banc. This Court's
jurisdiction is invoked under 28 U.S.C. § 1254(1).

CONSTITUTIONAL, STATUTORY, AND
REGULATORY PROVISIONS INVOLVED

Article I, § 1, of the Constitution provides in pertinent part
that “All legislative Powers herein granted shall be vested in a
Congress of the United States .. .”

The statutory and regulatory provisions relevant to this case
are set forth infra, App. 94-113.

STATEMENT

In 1997, EPA revised its existing air quality standards for
particulate matter (“PM”) and ozone. See National Ambient Air
Quality Standards for Particulate Matter, 62 Fed. Reg. 38,652,
38,655 (1997) (“PM Final Rule”); National Ambient Air
Quality Standards for Ozone, 62 Fed. Reg. 38,856, 38,860
(1997) (“Ozone Final Rule”). It acted on the basis of exhaustive
scientific inquiry into the nature and magnitude of the effects of
these pollutants on human health and welfare. EPA estimated
that its revised standards together could save as many as 15,000
additional lives per year as compared to the previous standard,
and also annually prevent hundreds of thousands of additional
cases of aggravated asthma and significantly decreased lung
function. '

The D.C. Circuit held that the Clean Air Act, as applied in
these rulemakings, delegates authority to the executive in
violation of the Constitution. The court also held that section
181 of the Act, 42 U.S.C. § 7511, prevents EPA from enforcing
the revised ozone standard.

Judge Tatel dissented from the panel’s decision on the
delegation question. (App. 55.) Five judges - a majority of
those participating - voted to rehear the case en banc. (App.
84.) But because D.C. Circuit rules require that a majority of
the court’s active sitting judges vote in favor of rehearing a case

'Hearing on Use of Fire As a Management Tool and Its
Risks and Benefits for Forest Health and Air Quality Before the
House Comm. On Resources, 105th Con. Ist Sess., Sept. 30,

en banc, and because two active judges did not participate in
the decision, rehearing en banc was denied.”

A. Statutory and Regulatory Background
1. Establishing and Revising the NAAQS

The Clean Air Act requires the Administrator
(“Administrator”) of EPA to establish and periodically revise
national ambient air quality standards (“NAAQS”) for a limited
subset of air pollutants. 42 U.S.C. §§ 7408-7409. These
standards identify the maximum permitted level of the regulated
pollutants in the outside air.”

NAAQS may be set only: for air pollutants that “cause or
contribute to air pollution which may reasonably be anticipated
to endanger public health or welfare” and “the presence of
which in the ambient air results from numerous or diverse
mobile or stationary sources.” 42 U.S.C. § 7408(a)(1)(A)-(B).
Thus NAAQS may be set only for widespread pollutants that
endanger public health or welfare. Today, NAAQS exist for six

Federal Rules of Appellate Procedure and
Corresponding Circuit Rules of the District of Columbia
Circuit, Rule 35(a) (circuit rules as amended through 1-3-00).

*Primary NAAQS are designed to protect the public
health. 42 U.S.C. § 7409(b)(1). Secondary standards are
designed to protect public welfare, id. § 7409(b)(2), broadly
defined to include, for example, effects on soils, crops, and
wildlife, id. § 7602(h). The primary and secondary standards at
issue here are identical. PM Final Rule, 62 Fed. Reg. at 38,683;
Ozone Final Rule, 62 Fed. Reg. at 38,877.

air pollutants: PM, sulfur dioxide, carbon monoxide, nitrogen
dioxide, ozone, and lead. See 40 C.F.R. §§ 50.4 - 50.12.

The Clean Air Act directs the Administrator to review the
NAAQS every five years. 42 U.S.C. § 7409(d)(1). Based on
this review, the Administrator may promulgate a new NAAQS,
or revise an existing one. /d. § 7409(a)(1). No new pollutant
has been regulated under the NAAQS program since 1978,
when the NAAQS for lead was issued.‘

The Clean Air Act requires extensive scientific inquiry into
the nature and severity of harm caused by an air pollutant before
a NAAQS for that pollutant can be established or revised. The
Act requires, first, that air quality “criteria” be developed for
pollutants in the NAAQS program. These criteria - which are
described in a “criteria document” prepared by the agency -
must reflect “the latest scientific knowledge” indicating the
“kind and extent of all identifiable effects on public health or
welfare.” 42 U.S.C. § 7408(a)(2).

The Act requires, in addition, that a scientific advisory
committee - known as the Clean Air Scientific Advisory
Committee, or “CASAC” - review the air quality criteria and
NAAQS. The committee must recommend to the
Administrator any new or revised NAAQS that may be
appropriate in light of the statutory requirements, and must also
describe the areas in which “additional knowledge” is required
to evaluate any NAAQS. 42 U.S.C. § 7409(d)(2)(B)-(C).

The NAAQS themselves must be “based on” the air quality
criteria. 42 U.S.C. § 7409(b)(1). They must be set at a level
which, “allowing an adequate margin of safety, are requisite to

*43 Fed. Reg. 46,246 (1978).

protect the public health.” Id. § 7409(b)(1). The Administrator
may significantly depart from the recommendations of CASAC
only if she explains why she has done so. Id. § 7607(d)(3).
EPA has consistently interpreted the Clean Air Act to require
the protection of sensitive subpopulations such as children, the
elderly, and people with respiratory problems. Lead Industries
Assoc. v. EPA, 647 F.2d 1130, 1153 (D.C. Cir. 1980).

2. Implementing the NAAQS

Once the NAAQS are established or revised, attention shifts
to achieving them. Although the Clean Air Act gives the states
the primary responsibility to implement the programs to achieve
the NAAQS, 42 U.S.C. § 7410, the statute also significantly
constrains the timing and content of the process of
implementation.

Designation: Attainment Status. Implementation begins with
the designation of areas according to whether their air quality
complies with the NAAQS. The three possible designations are
“attainment” (area meets the NAAQS), “nonattainment” (area
does not meet them), or “unclassifiable” (area’s attainment
status cannot be determined based on available information).

42 U.S.C. § 7407(d)( 1)(A)(4)-(iii).

Section 107(d) provides that areas may be designated at three
different points in time. First, areas may be designated when a
new NAAQS is established, or an existing one revised. 42
U.S.C. § 7407(d)(1). Second, areas were designated following
the 1990 Amendments to the Clean Air Act. Id. § 7407(d)(4).
Third, areas may be “redesignated” based on new information.
Id. § 7407(d)(3). For example, an attainment area may be
redesignated as nonattainment if its air quality ceases to meet
the NAAQS.

State Implementation Plans. The next step toward achieving
the NAAQS is for the states to submit state implementation
plans, or “SIPs.” 42 U.S.C. § 7410. These plans specify the
measures states will take to attain or maintain the NAAQS
within their borders. /d. § 7410(a)(1). A state may consider cost
and technological feasibility in developing its SIP; indeed, “[s]o
long as the national standards are met, the State may select
whatever mix of control devices it desires . . .” Union Electric
Company v. EPA, 427 U.S. 246, 266 (1976).

Nonattainment. Special rules apply with respect to areas
designated as nonattainment. Part D of Subtitle I sets forth
requirements for SIPs in states containing nonattainment areas.
42 U.S.C. §§ 7501-7515. Part D establishes both what is
required in the SIPs of states that contain nonattainment areas
and when it is required. Part D contains five subparts. Subpart
1 sets forth rules for nonattainment areas in general. 42 U.S.C.
§ 7501-7509a. Subparts 2-5, added to the Act in 1990, impose
new requirements on areas that were then in nonattainment for
any of the pollutants covered by the NAAQS. Id. §§ 7511-
75 14a.

Subpart 1. Under Subpart 1, after designating an area as
nonattainment under section 107(d), the Administrator may
“classify” the area, in accordance with the severity of its air
quality problem, for the purpose of setting a deadline for
attainment. 42 U.S.C. § 7502(a)(1)(A). The significance of -
classification is that nonattainment areas bearing different
classifications may be given different attainment dates.

Subpart | contains a number of specific requirements for the
SIPs in nonattainment areas. For example, these SIPs must
require “reasonable further progress” toward attaining the
NAAQS. With respect to timing, Subpart | provides that the
attainment date for areas not meeting a primary NAAQS is “as

6

expeditiously as practicable, but no later than 5 years from the
date such area was designated nonattainment .. .” 42 U.S.C.
§7502(a)(2)(A).

Subpart 2. Subpart 2 imposed new, more specific
requirements on areas that had not attained the ozone standard
existing in 1990, when Subpart 2 was enacted. Like Subpart |,
Subpart 2 prescribes both the general content of SIPs and the
deadlines for meeting statutory requirements and achieving the
NAAQS. The specific requirements and deadlines depend on
an area’s classification.

Section 181 of Subpart 2 provides, as its title says,
“classifications and attainment dates for 1989 nonattainment
areas.” 42 U.S.C.§ 7511. Areas “designated nonattainment for
ozone pursuant to section 7407(d)” are to be “classified at the
time of such designation, under table |, by operation of law ...”
Id. § 7511(aX(1). The classifications in table 1 range from
“marginal” to “extreme.” Id. § 7511(a)(1). These classifications
are tied to the area’s “design value,” which is measured in parts
per million (“ppm”) of ozone in the ambient air. /d. § 751 1(a)(1)
(table 1, n. *).

The design values in table | of section 181(a)(1) range from
0.121 to 0.280 and above. 42 U.S.C. § 7511(a)(1). The level
of the ozone standard in effect when section 181(a)(1) was
enacted was 0.12 ppm. Ozone Final Rule, at 38,857. Thus the
lowest of the “design values” reflected in table | of section
181(a)(1) is also the lowest ozone concentration that would
have qualified an area as nonattainment under the ozone
standard that existed in 1990.

Subpart 2’s specific requirements for SIPs are set forth in
sections 182-185B. 42 U.S.C. § 75lla-f. The requirements
escalate with each classification. See id.§ 751 la({a)-(e). All

7

nonattainment areas must meet the requirements set for any
areas with lower design values, plus additional, more stringent
requirements. For “marginal” areas, the SIP requirements
largely track those of Subpart 1. Jd. § 75lla(a). Areas
classified as “moderate” and above must also, for example,
measure their “baseline emissions” of ozone precursors in 1990,
and then demonstrate “reasonable further progress” - measured
according to specific percentage reductions in emissions — at
regular intervals. Jd. §§ 751 1a(b)(1), (c)-(e).

With respect to timing, section 181(a)(1) requires that
attainment of the NAAQS be achieved “as expeditiously as
practicable but not later than” the dates specified in that section.
42 U.S.C. § 7511(a)(1). These dates range from 1993 to 2010.
Id. § 7511(a)(1). States must also meet each of the SIP
requirements described above within a specified number of
years. Subpart 2 consistently specifies November 15, 1990, as
the date when the deadline “clock” for the SIP requirements
begins to run. Id. §§ 751 la(a)-(g).

Interstate Poilution. Air pollution does not respect political
boundaries. The Clean Air Act acknowledges this physical
reality in provisions that specifically target interstate air
pollution. Section 110(a)(2)(D) requires states to include
within their SIPs provisions to prevent sources within their
borders from “contribut[ing] significantly” to nonattainment in
other states. 42 U.S.C. § 7410(a)(2)(D). Section 110(k)(5)
requires EPA to call for revisions to a SIP when the SIP is
inadequate. 42 U.S.C. § 7410(k)(5). Such an action by EPA is
known as a “SIP call.” A SIP call may be based on EPA’s
finding that sources within a state are contributing significantly
to nonattainment in another state. This finding - called a
“section 126 finding” after the section of the Clean Air Act that
permits it - may be requested of EPA by any state experiencing
the ill effects of interstate pollution. 42 U.S.C. § 7426(b).

B. Rulemakings on Particulate Matter and Ozone
1. Particulate Matter

Particulate matter (“PM”) refers to a broad class of diverse
substances that exist as discrete particles over a wide range of
sizes. Particles originate from a variety of stationary and mobile
sources as well as from natural sources. EPA first promulgated
a NAAQS for PM in 1971. 36 Fed. Reg. 8186 (1971). In July
1987, EPA revised the standard, changing inter alia, the PM
indicator from total suspended particles to particulate matter
with an aerodynamic diameter of less than or equal to a nominal
ten micrometers (“PM”). 52 Fed. Reg. 24,854 (1987).

In April 1994, EPA announced its intention to develop a
revised air quality criteria document for PM. The focus of the
review was recent epidemiological evidence reporting
associations between ambient concentrations of PM and a range
of serious health effects, including effects caused by particulates
with an aerodynamic diameter far smaller than ten micrometers
(“PMio”). During the next two years, the agency held several
workshops, provided opportunities for public comment on a
draft criteria document, and sponsored CASAC review of the
document at public meetings.

On November 27, 1996, EPA announced its proposed
decision to revise the PM NAAQS. 61 Fed. Reg. 65,638
(1996). EPA proposed adding two new PM NAAQS that
measured particulates with an aerodynamic diameter less than
or equal to a nominal 2.5 micrometers (“PM2,5”). The proposal
also specified several other key parameters for the revised
standards: (1) concentration (level); (2) averaging time (the
period over which pollutant levels are averaged in measuring
compliance); and (3) form (the air quality statistic used as a

9

basis for determining compliance with the standard). The
Administrator described several alternative standards using
these parameters, including possible changes in the then-
existing PMjo NAAQS. 7d. at 65,662.

On July 18, 1997, EPA announced final revisions to its PM
NAAQS. 62 Fed. Reg. - 38,652 (1997). The Administrator
determined that it was appropriate to establish new annual and
24-hour NAAQS for PM255 and to revise the current 24-hour
PM\o standard.” The Administrator noted that that the agency
had undertaken an especially rigorous review and reanalysis of
existing scientific data and that recent studies provided
“evidence that serious health effects (mortality, exacerbation of
chronic disease, increased hospital admissions, etc.) are
associated with exposures to ambient levels of PM found in
contemporary U.S. urban airsheds even at concentrations below
current U.S. PM standard.” /d. at 38,655. The Administrator
further described the results of risk assessments of two cities
that, while accompanied by significant scientific uncertainty,
“found that the risk remaining after attaining the current PMjo
standards was on the order of hundreds of premature deaths
each year, hundreds to thousands of respiratory-related hospital
admissions, and tens of thousands of additional respiratory
related symptoms in children.” Jd. at 38,656.

‘For PM25, the EPA set a level of 15 g/m’ with
compliance measured based on the three-year average of the
annual artithmetic mean PM: concentrations from single or
multiple community-oriented monitors, and also set a level of
65 g/m? based on the three-year average of the 98th percentile
of 24-hour PM25 concentrations at each population-oriented
monitor within an area. For PMio, EPA changed the form of
the standard. PM Fina) Rule, 62 Fed. Reg. at 38,652.

2. Ozone

Ground-level ozone is formed as a result of chemical
reactions of volatile organic compounds, nitrogen oxides, and
oxygen in the presence of sunlight. EPA first issued a NAAQS
for ozone (or “photochemical oxidants”) in 1971. 36 Fed. Reg.
8187 (1971). The original standard specified a maximum level
of 0.08 ppm, averaged over one hour, with one exceedance
allowed per year. That standard was revised in 1979 by
increasing the allowable level to 0.12 ppm. 44 Fed. Reg. 8202
(1979).

The EPA initiated a review of the air quality criteria and
standards for ozone in August 1992. In an iterative process
involving EPA staff, CASAC, and the public, EPA developed
a criteria document on the health and welfare effects of ozone.

On November 27, 1996, EPA proposed to revise the NAAQS
for ozone. 61 Fed. Reg. 65,716. EPA proposed to replace the
one-hour, 0.12 ppm primary standard with an eight-hour, 0.08
ppm standard, with a new form for measuring compliance with
the standard. The proposal solicited comments on alternative
standards reflecting different levels, averaging times, and forms.
Id. at 65,731, 65,733.

On July 18, 1997, EPA announced final revisions to its
ozone NAAQS. 62 Fed. Reg. 38,856 (1997). The final rule set
a level of 0.08 ppm, with an averaging time of eight hours and
a form based on the 3-year average of the annual fourth-highest
daily maximum 8-hour average ozone concentrations measured
at each monitor within an area. /d. at 38,873.

11

In revising the ozone standard, the Administrator invoked a
large body of scientific evidence consisting of clinical,
epidemiological, and animal studies revealing the adverse
effects of ozone at levels allowed by the previous standard. 62
Fed. Reg. at 38,863-65. She cited “clear evidence from human
clinical studies” showing that the adverse effects from exposure
to ozone include “lung function decrements, respiratory
symptoms (e.g., cough, pain on deep inspiration), nonspecific
bronchial responsiveness, and biochemical indicators of
pulmonary inflammation.” /d. at 38,863. The Administrator
also cited the “numerous epidemiological studies [that] have
reported excess hospital admissions and emergency department —
visits for respiratory causes (for asthmatic individuals and the
general population) attributed primarily to ambient [ozone]
exposures, including [ozone] concentrations below the level of
the current standard, with no discernible threshold at or below
this level.” /d. at 38,864.

In setting the parameters for the revised ozone standard, the
Administrator noted that CASAC had unanimously endorsed an
eight-hour averaging period and that all CASAC members who
had expressed specific opinions on the form of the standard had
favored a form allowing multiple exceedances (as the final rule
did). 62 Fed. Reg. at 38,861, 38,869. As for the level of the
standard, the Administrator acknowledged that no one correct
policy response emerged from the scientific evidence. Id. at
38,863. In choosing between levels of 0.09, 0.08, and 0.07,
however, the Administrator placed “great weight” on the fact
that no member of CASAC had endorsed the 0.07 level, and
stressed that severity of effects decreased, and uncertainty
increased, at levels below 0.08 ppm. /d. at 38,854, 38,868. In
rejecting the 0.09 ppm level, the Administrator emphasized
that such a standard would result in many more adverse health

12

effects, particularly among children, than would the 0.08 ppm
level. Id. at 38,867-68.°
C. The Court of Appeals’ Initial Decision

Pursuant to section 107(b)(1) of the Clean Air Act, 42 U.S.C.
§ 7607(b)(1), numerous parties filed petitions for review of
EPA's revised standards in the D.C. Circuit.

1. Delegation

The D.C. Circuit found that EPA’s application of the Clean
Air Act in these rulemakings effected a “delegation of
legislative power” in violation of Article I, § 1, of the
Constitution. (App. 3.) The court explained that “EPA appears
to have articulated no ‘intelligible principle’ to channel its
application of the[] factors [it uses in setting NAAQS]; nor is
one apparent from the statute.” (App. 4.)

The court came to this conclusion based on its review of
EPA’s 1997 rulemakings on PM and ozone. The court found
the agency’s explanations for its rules constitutionally deficient
because they did not identify a “stopping point” for regulation.

(App. 10.) Although the court agreed that the factors EPA
considers in setting air quality standards - such as the nature

°In both rulemakings, EPA went to extraordinary
lengths to facilitate public participation: the agency established
a toll-free telephone hotline; set up a system enabling electronic
comments via the Internet; held multiple public meetings at
which over 400 citizens and organizations testified; fielded over
14,000 phone calls and over 4,000 electronic mail messages;
and held two national satellite telecasts to answer questions.
EPA also received over 50,000 written and verbal comments.
62 Fed. Reg. at 38,654; 62 Fed. Reg. at 38,858.

13

and severity of health effects, the size of the affected
population, and the kind of health information available and the
uncertainties surrounding it - were reasonable, it concluded that
these factors “do not themselves speak to the issue of degree.”
(App. 6.) The court also dismissed as irrelevant the exhaustive
scientific review underlying EPA’s standards. (App. 8.)

The court remanded the case to the agency rather than
overturning the pertinent statutory provisions outright. The
court acknowledged that its approach would not satisfy what it
called a “key function of non-delegation doctrine,” which is to
ensure that Congress, not the agency, exercises legislative
authority. (App. 12-13.) Indeed, the court conceded that under
its approach, “[t]he agency will make the fundamental policy
choices.” (App. 13.)

In closing, the court suggested the kinds of standards that
might pass constitutional muster after remand. Cost-benefit
analysis was the court’s first proposal, but the court
acknowledged that this option was not open to EPA given the
D.C. Circuit’s rulings interpreting the Clean Air Act to forbid
the consideration of costs. (App. 13.) Alternatively, the court
appeared to endorse the possibility of setting environmental
standards according to their effect on “quality-adjusted life-
years,” although it conceded that the Department of Health and
Human Services had determined that an approach of this sort
utilized by Oregon in the health-care context violated the
Americans with Disabilities Act. (App. 15 n. 5.)

2. Enforcement of Ozone Standard
The D.C. Circuit also addressed claims that EPA could
neither issue nor enforce a revised ozone standard. The court

found that EPA could indeed issue a revised ozone standard,
and also designate areas as nonattainment under the revised

1a

standard. (App. 31-34.) However, the court also concluded
that EPA could not enforce a revised ozone standard “other than
in accordance with the classifications, attainment dates, and
control measures set out in Subpart 2.” (App. 31.)

In other words, with respect to the timing of the achievement
of the revised ozone standard, the court of appeals’ ruling means
that EPA may not prescribe attainment dates different from
those specified in section 181(a)(1). EPA also may not classify
a nonattainment area other than in accordance with the
requirements of section 181(a)(1). As for the means of
achieving the revised ozone NAAQS, the court of appeals
barred EPA from requiring any control measures other than
those required by Subpart 2. (App. 31.)

The court found that section 181(a)(1), 42 U.S.C. §
7511(a)(1), was unambiguous. Because section 181(a)(1) refers
to nonattainment designations made under “section 7407(d),”
the court concluded that the classifications and attainment dates
specified by section 181(a)(1) apply to areas designated as
nonattainment under any of the provisions of section 107(d).
(App. 34-35.) This meant, according to the court, that areas
designated nonattainment under section 107(d)(1), following
the revision of a NAAQS, are also governed by Subpart 2.
Having found the statute clear, the court refused to defer to
EPA’s interpretation, which allowed enforcement of the revised
standard outside of Subpart 2. (App. 37-39.)

The court suggested that any other interpretation of section
181(a)(1) would not make sense. The court appeared to endorse
the reasoning of petitioners below that “because the 1990
amendments extended the time for nonattainment areas to
comply with the 0.12 ppm ozone NAAQS, they must preclude
EPA from requiring areas to comply either more quickly or with
a more stringent ozone NAAQS.” (App. 37.)

15

D. The Court of Appeals’ Partial Grant of Rehearing
and Denial of Rehearing En Banc

1. Delegation

The panel voted 2-1 to deny rehearing on the question
whether the Clean Air Act as applied in the PM and ozone
rulemakings unconstitutionally delegates legislative authority
to the executive. (App. 64-82.)

The court of appeals voted 5-4 in favor of rehearing the
delegation question en banc, but rehearing en banc was
nevertheless denied. (App. 84.) Judge Silberman wrote a
dissent from the denial of rehearing en banc. (App. 85-89.)

2. Enforcement of Ozone Standard

The pane! granted rehearing in part on the question whether
the revised ozone standard could be enforced. The panel
replaced the language in its initial opinion stating that EPA
“cannot be enforced by virtue of Clean Air Act § 181(a)” (App.
53) with language stating that EPA could enforce a revised
standard “only in conformity with Subpart 2.” (App. 75.)

Judge Tatel concurred in the partial grant of rehearing. He
believed that the modified opinion left “open the possibility that
EPA can enforce the new ozone NAAQS without conflicting
with Subpart 2’s classifications and attainment dates.” (App.
76.) He found that EPA may enforce the revised standard in

’The panel also modified its opinion to clarify that
“Subpart 2 erects no bar to the EPA’s requiring compliance with
a revised secondary ozone NAAQS ‘as expeditiously as
practicable.’” (App. 74.)

16

areas that have attained the former ozone standard, but not in
areas that have not yet attained that standard. (App. 81.)

REASONS FOR GRANTING THE PETITION

The D.C. Circuit's constitutional ruling is inconsistent with
over six decades of decisions from this Court upholding broad
assignments of authority from the legislative to the executive
branch. In comparison with standards this Court has upheld,
the Clean Air Act is far more restrictive of agency discretion.

Nothing in this Court’s nondelegation jurisprudence sanctions
the court of appeals’ unusual approach to delegation, according
to which the agency to which u:.constitutionally broad
discretion has supposedly been granted must supply quantitative
limits for its own discretion.

In addition, in preventing EPA from enforcing its revised
ozone standard, the court of appeals ignored the clear language
of the Clean Air Act. The result is to create a bizarre regulatory
scheme that is at odds with the Act’s language and purposes. At
the very least, the court of appeals should have deferred to EPA
as to the meaning of the relevant statutory provisions.

The D.C. Circuit's decision has enormous immediate
significance for the entire country. The decision places states’
regulatory obligations in a posture of extreme uncertainty, and
has enormous implications for the public health. There is now
no NAAQS in place in most of the country for ozone. In
addition, the ruling has delayed, and partially undermined,
petitioners’ longstanding efforts to reduce interstate air
pollution that places their citizens’ health at risk.

There is no reason to wait for a circuit split to develop as to

the constitutionality of the Clean Air Act or the enforceability
of the revised ozone standard. Such a split is impossible: only

17

the D.C. Circuit may review nationally applicable standards
issued under the Clean Air Act. 42 U.S.C. § 7607(b)(1). Thus
immediate review in this Court is warranted.

I. THE COURT OF APPEALS’ DECISION IS
INCONSISTENT WITH THIS COURT'S RULINGS ON
THE “DELEGATION’ DOCTRINE.

The Clean Air Act establishes minimum requirements for air
quality throughout the nation. The court of appeals ruled that
this statute, as interpreted by EPA and the courts for the last
three decades, is unconstitutional as a delegation of legislative
power. In doing so, the court ignored this Court’s decisions
upholding much broader assignments of authority to
administrative agencies than the assignment made by the Clean
Air Act. The court compounded its error when it then turned to
the agency itself to enunciate an “intelligible principle” in the
form of a meta-standard to govern future rulemakings.

In holding that the Clean Air Act enunciates no “intelligible
principle” limiting agency action, the court of appeals departed
from over six decades of unbroken precedent from this Court
finding such a principle in statutes far less constraining than the
Clean Air Act. During this period, this Court has, “without
deviation,” upheld Congress’s authority to seek assistance from
administrative agencies under “broad standards.” Mistretta v.
United States, 488 U.S. 361, 373 (1989). For example, this
Court has affirmed the Federal Communications Commission’s
authority to regulate broadcast licensing in the “public interest,”
National Broadcasting Co. v. United States, 319 U.S. 190, 225-
26 (1943), and to issue regulations “as public convenience,
interest, or necessity requires,” United States v. Southwestern
Cable Co., 392 U.S. 157, 178 (1968); the Federal Power
Commission’s authority to determine “just and reasonable”
rates, FPA v. Hope Natural Gas Co., 320 U.S. 591, 600 (1944);

18

Te ee ee ee ee

and the Attorney General’s authority - even absent notice and
comment rulemaking - to designate controlled substances and
criminalize their manufacture, possession, and use, Touby v.
United States, 500 U.S. 160 (1991).

The Clean Air Act constrains agency discretion at least as
much as the statutory standards this Court has previously
upheld. First, NAAQS apply to only a handful of pollutants -
widespread pollutants (i.e., those from “numerous and diverse
sources”) that endanger public health or welfare. Thus the
territory over which EPA’s discretion may range is limited.

Second, the Act requires extensive scientific inquiry into the
nature and severity of harm caused by an air pollutant. The
development of criteria documents, identifying the “kind and
extent of all identifiable effects on public health or welfare,” 42
U.S.C. § 7408(a)(2), and the submission of the criteria
documents and NAAQS themselves to CASAC’s review, id. §
7409(d)(2)(B), ensure that NAAQS will emerge from the best
available scientific evidence.

Third, in actually setting NAAQS, EPA’s discretion is
constrained in several important ways. NAAQS must be set at
a level which, “allowing an adequate margin of safety, are
requisite to protect the public health.” 42 U.S.C. § 7409(b)(1).
The use of the term “requisite” limits EPA’s standard-setting
discretion on the low end. In addition, NAAQS must be “based
on” the air quality criteria. Id. § 7409(b)(1). These criteria
must themselves be based on the latest scientific information as
to the “kind and extent” of effects of the relevant air pollutants
on human health and welfare. Jd. § 7408(a)(2). By explicitly
focusing the scientific inquiry on the “kind and extent” of
human health effects, the Act communicates to EPA an intent
to distinguish among health effects based on their severity and
magnitude. This is just what EPA did in the rules at issue here.

19

See, e.g., Ozone Final Rule, 62 Fed. Reg. at 38,859, 38,860,
38,864. Moreover, the Administrator may significantly depart
from CASAC’s recommendations only if she explains why she
has done so. /d. § 7607(d)(3). In this case, when CASAC-was
able to achieve a consensus, the Administrator's actions hewed
closely to it. In setting the ozone standard, for example, the
Administrator considered ozone levels only within a range
approved by CASAC, and declined to set the standard at the
lowest end of that range in part because no member of CASAC
had endorsed such a low standard. Ozone Final Rule, 62 Fed.
Reg. at 38,861, 38,868.

Finally, the Administrator's discretion in promulgating
NAAQS is constrained by the fact that her actions are subject
to the exaciing requirements of the Administrative Procedure
Act, and are subject to judicial review for arbitrariness. This
Court has suggested that procedural requirements and the
availability of judicial review are important factors in
evaluating the propriety of Congress’s assignments of authority
to the executive branch. American Power & Light Co. v. SEC,
329 U.S. 90, 105 (1946); Touby v. United States, 500 U.S. 160,
168-69 (1991).

Given the constraints the Clean Air Act imposes on EPA, the
Act should have unquestionably survived constitutional scrutiny
under this Court’s precedents. However, even though the court
of appeals explicitly held that the Clean Air Act does not
provide the “intelligible principle” necessary for purposes of the
delegation doctrine (App. 4), the court did not look in any detail
at what the Clean Air Act does. Instead, it examined what EPA
did, and concluded that because EPA had not identified a
precise “stopping point” for regulation, its actions were
unconstitutional. (App. 10.) Although the court of appeals did
not say so explicitly, close examination of the alternative
approaches the court endorsed reveals that the court appears to

20

have believed that EPA must - as a matter of constitutional
principle - quantify the point at which it will stop regulating to
protect human health. (App. 13, 15 (proposing cost-benefit
analysis and “quality-adjusted life-years” as antidotes to an
unconstitutional delegation)).

In not one of the “nondelegation” cases cited above did the
statutory standard upheld by this Court specify a precise
stopping point for achievement of desired ends such as the
public interest and justice. And in none of these cases did this
Court suggest that the agency must supply such a stopping point
if Congress does not. Allowing an agency to supply the
“intelligible principle” that this Court has required (and the
court of appeals erroneously found lacking here) is perverse in
light of the essential purpose of the nondelegation doctrine,
which is to ensure that Congress, not the agency, makes basic
policy choices. By requiring of the agency a precise stopping
point for regulation, the court below introduced a principle new
to constitutional law — that agencies must, in advance of
specific rulemakings, develop a meta-standard quantifying the
precise tradeoffs they will make among the broad purposes they
are charged to serve.

II. THE COURT OF APPEALS’ DECISION BLOCKING
ENFORCEMENT OF THE REVISED OZONE
STANDARD IS INCONSISTENT WITH THE
CLEAN AIR ACT’S LANGUAGE AND
PURPOSES, AND WITH EPA’S REASONABLE
INTERPRETATION OF THE ACT.

The court of appeals held that EPA was required to review
the ozone standard, and to revise it if appropriate, every five
years, and also to designate areas as nonattainment for ozone in
light of the revised standard. (App. 31-34.) Nevertheless, the
court held that EPA could not enforce this revised standard

21

“other than in accordance with the classifications, attainment
dates, and control measures set out in Subpart 2.” (App. 31.)
EPA may not, in other words, require the states to do anything
more to achieve the revised ozone NAAQS than they were
already required to do in order to achieve the former ozone
NAAQS.

In short, according to the D.C. Circuit, EPA can be required
by section 109 to promulgate a revised ozone standard
necessary to safeguard public health and welfare but the agency
is powerless to enforce that standard no matter how serious and
widespread the public health consequences of such compelled
agency inaction. Nowhere, however, does the Clean Air Act
suggest, let alone compel, a finding that Congress intended such
a perverse result.

Certainly, section 181, upon which the D.C. Circuit relied
(App. 35), reveals no indicia of such congressional intent.

*In concurring in the partial grant of rehearing, Judge
Tatel read the revised majority opinion as allowing EPA to
enforce the revised ozone standard in areas that have attained
the former standard. (App. 81.) Given the critical importance
of this issue, the panel’s failure to engage Judge Tatel’s view
creates doubt as to whether this interpretation is accurate. In
addition, the panel’s explanation for its decision not to vacate
the revised ozone standard - that the standard was not “likely to
engender costly compliance activities”in light of the court’s
holding on Subpart 2 (App. 75) - is hard to reconcile: with
Judge Tatel’s perspective on the panel’s opinion. In any event,
even if Judge Tatel’s interpretation of the panel’s opinion were
accurate, the panel’s opinion still raises enormous legal and
practical problems regarding EPA enforcement of the new
standard in areas that have not attained the former standard.

22

Section 181(a)(1), table 1, provides classifications and
attainment dates only for the former ozone standard, not for the
revised standard. This is clear from the language of the
provision itself. First, table 1 of section 181(a)(1) classifies
areas according to a “design value” which is measured in parts
per million (“ppm”). The lowest design value reflected in table
1 is 0.121 ppm. The range of design values in table 1 is thus
clearly keyed to the former ozone standard of 0.120 ppm. This
interpretation is reinforced by the title of section 181(a)(1),
“Classification and attainment dates for 1989 nonattainment
areas”; this language also indicates that section 181(a)(1)
specifies classifications and attainment dates only for areas in
nonattainment for the ozone standard existing in 1990.

The court’s ruling also makes a hash of section 181(a)(1)’s
language specifying the procedure for designation and
classification. According to the court, EPA must designate
areas as nonattainment (or attainment, or unclassifiable) under
the revised, eight-hour, 0.08 ppm ozone standard. (App. 33-
34.) Because section 181(a)(1) provides that classification must
occur “at the time of . . . designation,” 42 U.S.C. § 7511(a)(1),
EPA will also be required, at the same time, to classify the areas
designated as nonattainment under the revised standard.
However, section 181(a)(1) also requires that classifications be
based on the design value as calculated by the interpretation
methodology existing in November 1990. Jd. § 7511(a)(1).
This methodology looked to the ozone standard existing in
1990, not the revised ozone standard existing now.’ For this
reason, and because the court of appeals has required EPA to

*See Memorandum from William G. Laxton, Director,
Technical Support Division, U.S. EPA, “Ozone and Carbon
Monoxide Design Value Calculations” (June 18, 1990)
(http:www.epa.gov/airprogm/oar/oaqps/greenbk/laxton.html).

23

classify areas under the terms of section 181(a)(1), EPA’s new
classifications under the revised standard will be based on
design values calculated according to the former ozone
standard, not the revised standard. Thus, in classifying areas
under the revised standard EPA will be required to disregard the
design values it calculated in order to designate areas under that
standard. The court of appeals’ interpretation turns section
181(a)(1) into a kind of parody.

Recognizing that section 181(a)(1) specifies classifications
and attainment dates only for the ozone standard in effect in
1990 is also the only way sensibly to reconcile section 181(a)(1)
with EPA's continuing responsibility to revise the NAAQS. As
the court of appeals itself confirmed (App. 31-34), section 109
of the Clean Air Act requires EPA to review and, if appropriate,
revise the NAAQS every five years. After issuing a revised
NAAQS, EPA has two years to designate areas as attainment;
nonattainment, or unclassifiable. 42 U.S.C. § 7407(d)(1). The
review and revision of NAAQS, and the designation of areas
according to their attainment status, are resource-intensive,
time-consuming processes undertaken for a single purpose: to
achieve healthful air quality for the citizens of the country. On
the court of appeals’ interpretation of the Clean Air Act,
however, EPA's obligation to review and revise the ozone
NAAQS, and to designate areas according to their attainment
status, has no purpose other than to brand areas with the
unwelcome label “nonattainment.”

There is no warrant, in the language, structure, or history of
the Clean Air Act, for requiring EPA to engage in such a
pointless endeavor. In the Clean Air Act, Congress established
means for EPA to protect public health in light of scientific
evidence of the devastating health effects of air pollution - not
means for the agency to announce that air quality is bad but at
the same time limit EPA’s ability to mitigate it.

24

ee eee

The reference to “section 107(d)” in section 181(a)(1), on
which the court of appeals so heavily relied, does not support a
different conclusion. In finding that Congress's failure to refer
specifically to section 107(d)(4) (rather than to section 107(d)
as a whole), meant that EPA could not enforce the revised
ozone standard except in conformity with Subpart 2, the court
of appeals ignored all the rest of the language in Subpart 2,
which requires the opposite conclusion. The consistent
exclusive focus of Subpart 2 is the ozone NAAQS existing at
the time Congress added Subpart 2 in 1990.

At the very least, the cascade of language in Subpart 2
indicating that Subpart 2 applies only to the former, one-hour
ozone standard, combined with the absence of the single
number (4) in section 181(a)(1), creates an ambiguity that EPA
is entitled to resolve as long as it does so reasonably. Chevron
U.S.A. Inc. v. NRDC, 467 U.S. 837, 866 (1984). As set forth
above, EPA's interpretation of Subpart 2 to apply only to the
ozone standard existing in 1990 creates a sensible regulatory
regime in which EPA is not forced to revise a NAAQS, and to
designate areas according to their attainment status under the
revised NAAQS, only to be barred from taking steps to achieve
the NAAQS.

lil. THE COURT OF APPEALS’ DECISION
WARRANTS REVIEW, NOTWITHSTANDING
THE ABSENCE OF A DIRECT CIRCUIT
CONFLICT, BECAUSE OF ITS ENORMOUS
SIGNIFICANCE BOTH TO THE STATES AND
FOR THE PUBLIC HEALTH AND BECAUSE NO
SUCH CONFLICT IS POSSIBLE

Review of the court of appeals’ ruling is further warranted
because of its enormous significance to the states, including

25

petitioners Massachusetts and New Jersey, and to the public
health. The rules at stake in this litigation are among the single
most important national environmental standards promulgated
in over a decade. They implicate the viability of massive
regulatory programs which rely upon both the validity and
enforceability of the revised ozone and PM NAAQS. Also at
Stake are the thousands of deaths and hundreds of thousands of
illnesses that the Administrator concluded would be prevented
only by attainment of the revised NAAQS. These enormous
stakes alone would warrant this Court’s review, even without a
circuit conflict. Certainly, the absence of such a conflict should
not bar this Court’s review where, as here, the D.C. Circuit’s
exclusive jurisdiction makes the development of such a conflict
impossible. '°

A. The Ruling Has Great Practical Significance for the
States.

All states have an interest, as sovereigns, in being certain of
their rights and responsibilities under the Clean Air Act. The
D.C. Circuit's ruling has placed those rights and responsibilities
in a posture of extreme uncertainty in two respects: (1) the
ruling has delayed and undermined longstanding efforts to
reduce interstate air pollution; and (2) the former ozone

Petitioners have not sought review as to two other
issues decided below. The court held that EPA should have
considered the alleged health benefits of ozone in setting the
ozone standard, and that EPA’s choice of PMjo as an indicator
for coarse particulate matter was arbitrary and capricious.
(App. 41-50.) Unlike the court’s rulings on delegation and on
the enforceability of the revised ozone standard, these rulings
do not undermine the entire analytical framework and
implementation scheme on which the Clean Air Act depends.

26

standard has been revoked in most of the country and, as a
result of the D.C. Circuit's ruling on Subpart 2 of the Clean Air
Act, no enforceable standard has taken its place.

The ruling below has undermined petitioners’ longstanding
efforts to reduce the pollution that arrives inside their borders
from other states. These efforts have led to “SIP calls” from
EPA, requiring certain states to develop plans to reduce their
emissions of oxides of nitrogen (major ozone precursors) in
order to facilitate compliance with the NAAQS for ozone. See
Finding of Significant Contribution and Rulemaking for Certain
States in the Ozone Transport Assessment Group Region for
Purposes of Reducing Regional Transport of Ozone, 63 Fed.
Reg. 57,356 (Oct. 27, 1998). Petitioners’ efforts have also
resulted in “section 126 findings” from EPA, concluding that
sources from other states have “significantly contribute[d]” to
Massachusetts’ failure to attain the air quality standard for
ozone. See Findings of Significant Contribution and
Rulemaking on Section 126 Petitions for Purposes of Reducing
Interstate Ozone Transport; Final Rule, 65 Fed. Reg. 2674 (Jan.
18, 2000).

The ruling below has hindered petitioners’ efforts to reduce
interstate air pollution. As a result of the ruling, EPA scaled
back its section 126 findings that other states were significantly
contributing to the section 126 petitioners’ inability to meet
national air quality standards. See 64 Fed. Reg. 28,294-95
(tables showing broader geographic coverage under revised,
eight-hour standard than under former, one-hour standard). In
addition, the D.C. Circuit has temporarily stayed the “SIP calls”
described above. Order on Stay, State of Michigan v. EPA, No.
98-1497 (D.C. Cir.) (May 25, 1999).

In short, the D.C. Circuit's ruling has had large ripple effects
on the nation’s program for achieving clean air. In holding the

27

ozone standard unlawful on constitutional grounds, and in
blocking the enforcement of the ozone standard, the D.C.
Circuit has, apparently unwittingly,'' rent asunder EPA's
carefully crafted, multi-prong, multi-state attack on ozone. It
has also rendered more difficult petitioners’ efforts to protect
the health of their citizens through achievement of the NAAQS.

In addition, as a result of the ruling, there is now no
enforceable ozone standard in effect in most of the country. In
1997, in light of the promulgation of revised standards for PM
and ozone, President Clinton issued a memorandum to EPA in
which he ordered EPA to begin revoking the former standards
for ozone and PM in areas that had not exceeded those
standards for three years. 62 Fed. Reg. 38,421 (July 16, 1997).
EPA subsequently determined that the one-hour ozone standard
was no longer applicable in 2,945 of the nation’s 3,153
counties. 63 Fed. Reg. 31,014 (June 5, 1998); 63 Fed. Reg.
34,432 (July 22, 1998); 64 Fed. Reg. 30,911 (June 9, 1999).

EPA has issued a proposed rule rescinding its revocation of
the one-hour ozone standard. Rescinding Findings that the 1-
Hour Ozone Standard No Longer Applies in Certain Areas, 64
Fed. Reg. 57,424 (Oct. 25, 1999). The ultimate legal status of
EPA’s rescission of its revocation of the ozone standard has yet
to be determined. This much is certain, however: there is now
no enforceable ozone standard in place in most of the country,
and the decision below has at least cast a shadow over EPA’s

''A recent opinion written by Judge Williams asserts
that the 0.12 ppm, one-hour ozone standard “remains in place.”
American Petroleum Institute v. EPA, 2000 U.S. App. LEXIS
14 *4n. 1 (Jan. 4, 2000). However, as discussed in this section,
that standard has been revoked in most of the country.

efforts to reinstate the former ozone standard. This situation
creates enormous uncertainty for the states as regulators.

This uncertainty is exacerbated by the precipitousness of the
D.C. Circuit's ruling on delegation. The court failed to consider
many nonconstitutional issues presented to it, delaying their
resolution until EPA complied with the court’s new
constitutional rule. (App. 4.) The court’s decision threatens to
turn this rulemaking into an endless, iterative process in which
the agency must seek serial judicial approval of its standards.
This places the states in the untenable position of trying to
respond to complex standards that may, or may not, be undone
by the next round of judicial review.

B. The Implications for Public Health Are Enormous.

In 1997, EPA found that the existing standards for PM and
ozone were inadequate to protect the public health. Indeed, it
concluded that if the existing standards were left in place, as
many as 15,000 people would die prematurely, and hundreds of
thousands more would fall ill, experience respiratory problems,
miss work or school, and/or be admitted to the hospital, every
year. These factual findings were reached after multiple
exchanges between EPA and CASAC regarding the latest
scientific evidence of the public health effects of PM and ozone.

Because the court of appeals struck down the NAAQS and
never disputed these factual findings, the enormous public
health consequences of that ruling cannot now be gainsaid.

C. A Direct Circuit Conflict Is Impossible.
The absence of a direct circuit conflict does not counsel
against this Court’s review. Judicial review of nationally

applicable regulations promulgated under the Clean Air Act is
available exclusively in the D.C. Circuit. 42 U.S.C. §

29

7607(b)(1). Thus a circuit split will never develop as to the
constitutional and statutory questions presented here. Unless
this Court grants review of the D.C. Circuit’s decision, a panel
opinion of just two judges - which a majority of the judges
participating in the decision whether to rehear the case en banc
believed sufficiently problematic to warrant en banc review -
will govern the validity and enforceability of the national air
quality program.

If allowed to stand, the two-judge ruling on delegation will
control not only EPA’s standards for PM and ozone, but also its
standards for the other air pollutants regulated by NAAQS. The
agency is just now in the process of reworking its standard for
sulfur dioxide.'? Given the monumental amount of time and
resources involved in reviewing and revising NAAQS, this
Court's immediate review is warranted to prevent EPA's
standard-setting process from taking place under a cloud of
constitutional doubt.

In reaching the question of delegation, two judges held
invalid EPA’s administration of what is perhaps the nation’s
premier environmental program on the basis of a perfunctory,
one-sentence argument in two parties’ briefs. This Court’s
review is warranted in order to give the constitutional question,
and the Clean Air Act itself, the careful hearing they deserve.

CONCLUSION

The petition for a writ of certiorari should be granted.

PER CURIAM:
Introduction

The Clean Air Act requires EPA to promulgate and
periodically revise national ambient air quality standards
("NAAQS") for each air pollutant identified by the agency as
meeting certain statutory criteria. See Clean Air Act §§ 108-09,
42 U.S.C. §§ 7408-09. For each pollutant, EPA sets a "primary
standard"~a concentration level "requisite to protect the public
health” with an "adequate margin of safety"--and a "secondary
standard"--a level “requisite to protect the public welfare." Id.
§ 7409(b).

App. 3

In July 1997 EPA issued final rules revising the primary
and secondary NAAQS for particulate matter ("PM") and
ozone. See National Ambient Air Quality Standards for
Particulate Matter, 62 Fed. Reg. 38,652 (1997) ("PM Final
Rule"); National Ambient Air Quality Standards for Ozone, 62
Fed. Reg. 38,856 (1997) ("Ozone Final Rule"). Numerous
petitions for review have been filed for each rule.

In Part I we find that the construction of the Clean Air
Act on which EPA relied in promulgating the NAAQS at issue
here effects an unconstitutional delegation of legislative power.
See U.S. Const. art. I, § 1 ("All legislative powers herein
granted shal! be vested in a Congress of the United States.").
We remand the cases for EPA to develop a construction of the
act that satisfies this constitutional requirement.

In Part II we reject the following claims: that § 109(d)
of the Act allows EPA to consider costs; that EPA should have
considered the environmental damage likely to result from the
NAAQS' financial impact on the Abandoned Mine Reclamation
Fund; that the NAAQS revisions violated the National
Environmental Policy Act ("NEPA"), Unfunded Mandates
Reform Act ("UMRA"), and Regulatory Flexibility Act
("RFA").

In Part III we decide two ozone-specific statutory issues,
holding that the 1990 revisions to the Clean Air Act limit EPA's
ability to enforce new ozone NAAQS and that EPA cannot
ignore the possible health benefits of ozone.

Finally, in Part IV we resolve various challenges to the
PM NAAQS. We agree with petitioners that EPA's choice of
PM,, as the indicator for coarse particulate matter was arbitrary
and capricious; we reject petitioners’ claims that EPA must treat
PM,,, as a "new pollutant," that EPA must identify a biological

App. 4

mechanism explaining PM's harmful effects, and that the Clean
Air Act requires secondary NAAQS to be set at levels that
eliminate all adverse visibility effects.

The remaining issues cannot be resolved until such time
as EPA may develop a constitutional construction of the act
(and, if appropriate, modify the disputed NAAQS in accordance
with that construction).

I. Delegation

Certain "Small Business Petitioners" argue in each case
that EPA has construed §§ 108 & 109 of the Clean Air Act so
loosely as to render them unconstitutional delegations of
legislative power. We agree. Although the factors EPA uses in
determining the degree of public health concern associated with
different levels of ozone and PM are reasonable, EPA appears

to have articulated no "intelligible principle" to channel its
application of these factors; nor is one apparent from the
statute. The nondelegation doctrine requires such a principle.
See J.W. Hampton, Jr. & Co. v. United States, 276 U.S. 394,
409, 72 L. Ed. 624, 48 S. Ct. 348 (1928). Here it is as though
Congress commanded EPA to select “big guys," and EPA
announced that it would evaluate candidates based on height
and weight, but revealed no cut-off point. The announcement,
though sensible in what it does say, is fatally incomplete. The
reasonable person responds, "How tall? How heavy?"

EPA regards ozone definitely, and PM likely, as
nonthreshold pollutants, i.e., ones that have some possibility of
some adverse health impact (however slight) at any exposure
level above zero. See Ozone Final Rule, 62 Fed. Reg. at
38,863/3 ("Nor does it seem possible, in the Administrator's
judgment, to identify [an ozone concentration] level at which it
can be concluded with confidence that no ‘adverse’ effects are

App. 5

likely to occur."); National Ambient Air Quality Standards for
Ozone and Particulate Matter, 61 Fed. Reg. 65,637, 65,651/3
(1996) (proposed rule) ("The single most important factor
influencing the uncertainty associated with the risk estimates is
whether or not a threshold concentration exists below which
PM-associated health risks are not likely to occur."). For
convenience, we refer to both as non-threshold pollutants; the
indeterminacy of PM's status does not affect EPA's analysis, or
ours.

Thus the only concentration for ozone and PM that is
utterly risk-free, in the sense of direct health impacts, is zero.
Section 109(b)(1) says that EPA must set each standard at the
level “requisite to protect the public health" with an "adequate
margin of safety." 42 U.S.C. § 7409(b)(1). These are also the
criteria by which EPA must determine whether a revision to
existing NAAQS is appropriate. See 42 U.S.C. § 7409(d)(1)
(EPA shall "promulgate such new standards as may be
appropriate in accordance with ... [ § 7409(b)]"); see also nifra
Part II.A. For EPA to pick any non-zero level it must explain
the degree of imperfection permitted. The factors that EPA has
elected to examine for this purpose in themselves pose no
inherent nondelegation problem. But what EPA lacks is any
determinate criterion for drawing lines. It has failed to state
intelligibly how much is too much.

We begin with the criteria EPA has announced for
assessing health effects in setting the NAAQS for non-threshold
pollutants.' They are “the nature and severity of the health

'Technically, EPA describes the criteria as used only for
setting the "adequate margin of safety.” There might be thought
to be a separate step in which EPA determines what standard
would protect public health without any margin of safety, and
that step might be governed by different criteria. But EPA did

App. 6

effects involved, the size of the sensitive population(s) at risk,
the types of health infurmation available, and the kind and
degree of uncertainties that must be addressed." Ozone Final
Rule, 62 Fed. Reg. at 38,883/2; EPA, "Review of the National
Ambient Air Quality Standards for Particulate Matter: Policy
Assessment of Scientific and Technical Information: OAQPS
Staff Paper," at II]-2 (July 1996) ("PM Staff Paper") (listing
same factors). Although these criteria, so stated, are a bit vague,
they do focus the inquiry on pollution's effects on public health.
And most of the vagueness in the abstract formulation melts
away as EPA applies the criteria: EPA basically considers
severity of effect, certainty of effect, and size of population
affected. These criteria, long ago approved by the judiciary, see
Lead Industries Ass'n v. EPA, 208 U.S. App. D.C. 1, 647 F.2d
1130, 1161 (D.C. Cir. 1980) ("Lead Industries"), do not
themselves speak to the issue of degree.

Read in light of these factors, EPA's explanations for its
decisions amount to assertions that a less stringent standard
would allow the relevant pollutant to inflict a greater quantum
of harm on public health, and that a more stringent standard
would result in less harm. Such arguments only support the
intuitive proposition that more pollution will not benefit public
health, not that keeping pollution at or below any particular
level is "requisite" or not requisite to "protect the public health"
with an “adequate margin of safety," the formula set out by §
109(b)(1).

Consider EPA's defense of the 0.08 ppm level of the
ozone NAAQS. EPA explains that its choice is superior to

not use such a process, and it need not. See NRDC v. EPA, 284
U.S. App. D.C. 136, 902 F.2d 963, 973 (D.C. Cir. 1990). Thus,
the criteria mentioned in the text govern the whole
standard-setting process.

App. 7

retaining the existing level, 0.09 ppm, because more people are
exposed to more serious effects at 0.09 than at 0.08. See Ozone
Final Rule, 62 Fed. Reg. at 38,868/1. In defending the decision
not to go down to 0.07, EPA never contradicts the intuitive
proposition, confirmed by data in its Staff Paper, that reducing
the standard to that level would bring about comparable
changes. See EPA, "Review of National Ambient Air Quality
Standards for Ozone: Assessment of Scientific and Technical
Information: OAQPS Staff Paper," at 156 (June 1996) ("Ozone
Staff Paper"). Instead, it gives three other reasons. The principal
substantive one is based on the criteria just discussed:

The most certain O,-related effects, while judged to be
adverse, are transient and reversible (particularly at O,
exposures below 0.08 ppm), and the more serious
effects with greater immediate and potential long-term
impacts on health are less certain, both as to the
percentage of individuals exposed to various
concentrations who are likely to experience such effects
and as to the long-term medical significance of these
effects.

Ozone Final Rule, 62 Fed. Reg. at 38,868/2.

In other words, effects are less certain and less severe at
lower levels of exposure. This seems to be nothing more than
a statement that lower exposure levels are associated with lower
risk to public health. The dissent argues that in setting the
standard at 0.08, EPA relied on evidence that health effects
occurring below that level are "transient and reversible,"
Dissent at 5, evidently assuming that those at higher levels are
not. But the EPA language quoted above does not make the
categorical distinction the dissent says it does, and it is far from
apparent that any health effects existing above the level are
permanent or irreversible.

App. 8

In addition to the assertion quoted above, EPA cited the
consensus of the Clean Air Scientific Advisory Committee
("CASAC") that the standard should not be set below 0.08.
That body gave no specific reasons for its recommendations, so
the appeal to its authority, also made in defense of other
standards in the PM Final Rule, see PM Final Rule, 62 Fed.
Reg. at 38,677/2 (daily fine PM standard); id. at 38,678/3
(annual coarse PM standard); id. at 38,679/1 (daily coarse PM
standard), adds no enlightenment. The dissent stresses the
undisputed eminence of CASAC's members, Dissent at 4, but
the question whether EPA acted pursuant to lawfully delegated
authority is not a scientific one. Nothing in what CASAC says
helps us discern an intelligible principle derived by EPA from
the Clean Air Act.

Finally, EPA argued that a 0.07 standard would be
“closer to peak background levels that infrequently occur in
some areas due to nonanthropogenic sources of O, precursors,
and thus more likely to be inappropriately targeted in some
areas on such sources." Ozone Final Rule, 62 Fed. Reg. at
38,868/3. But a 0.08 level, of course, is also closer to these peak
levels than 0.09.

The dissent notes that a single background observation
fell between 0.07 and 0.08, and says that EPA's decision
"ensured that if a region surpasses the ozone standard, it will do
so because of controllable human activity, not uncontrollable
natural levels of ozone." Dissent at 6. EPA's language, coupled
with the data on background ozone levels, may add up to a
backhanded way of saying that, given the national character of
the NAAQS, it is inappropriate to set a standard below a level
that can be achieved throughout the country without action
affirmatively extracting chemicals from nature. That may well
be a sound reading of the statute, but EPA has not explicitly
adopted it.

App. 9

EPA frequently defends a decision not to set a standard
at a lower level on the basis that there is greater uncertainty that
health effects exist at lower levels than the level of the standard.
See Ozone Final Rule, 62 Fed. Reg. at 38,868/2; PM Final
Rule, 62 Fed. Reg. at 38,676/3 (annual fine PM standard); id.
at 38,677/2 (daily fine PM standard). And such an argument is
likely implicit in its defense of the coarse PM standards. See
PM Final Rule, 62 Fed. Reg. at 38,678/3- 79/1. The dissent's
defense of the fine particulate matter standard cites exactly such
a justification. See Dissent at 6 ("The Agency explained that
‘there is generally greatest statistical confidence in observed
associations ... for levels at and above the mean concentration
[in certain studies]' *) (emphasis added in dissent). But the
increasing-uncertainty argument is helpful only if some
principle reveals how much uncertainty is too much. None
does.

The arguments EPA offers here show only that EPA is
applying the stated factors and that larger public health narms
(including increased probability of such harms) are, as
expected, associated with higher poliutant concentrations. The
principle EPA invokes for each increment in stringency (such
as for adopting the annual coarse particulate matter standard
that it chose here)--that it is "possible, but not certain" that
health effects exist at that level, see PM Final Rule, 62 Fed.
Reg. at 38,678/3 ? --could as easily, for any non-threshold

EPA did cite qualitative evidence for further support
for its annual standard, and argued that the evidence "does not
provide evidence of effects below the range of 40-50 Sg/m3,”
the standaru level. PM Final Rule, 62 Fed. Reg. at 38,678/3.
The referenced document, however, bears no indication that the
qualitative evidence demonstrates effects at the level of the
standard, either. See EPA, "Air Quality Criteria for Particulate
Matter," at 13-79 (April 1996).

App. 10

pollutant, justify a standard of zero. The same indeterminacy
prevails in EPA's decisions not to pick a still more stringent
level. For example, EPA's reasons for not lowering the ozone
standard from 0.08 to 0.07 ppm--that "the more serious effects
... are less certain" at the lower levels and that the lower levels
are "closer to peak background levels," see Ozone Final Rule,
62 Fed. Reg. at 38,868/2--could also be employed to justify a
refusal to reduce levels below those associated with London's
"Killer Fog" of 1952. In that calamity, very high PM levels (up
to 2,500 Sg/m3) are believed to have led to 4,000 excess deaths
in a week.’ Thus, the agency rightly recognizes that the
question is one of degree, but offers no intelligible principle by
which to identify a stopping point.

The latitude EPA claims here seems even broader than
that OSHA asserted in International Union, UAW v. OSHA
("Lockout/Tagout I"), 291 U.S. App. D.C. 51, 938 F.2d 1310,
1317 (D.C. Cir. 1991), which was to set a standard that would
reduce a substantial risk and that was not infeasible. In that
case, OSHA thought itself free either to "do nothing at all" or
to "require precautions that take the industry to the brink of
ruin,” with "all positions in between ... evidently equally valid."
Id. Here, EPA's freedom of movement between the poles is
equally unconstrained, but the poles are even farther apart--the
maximum stringency would send industry not just to the brink
of ruin but hurtling over it, while the minimum stringency may
be close to doing nothing at all.

In Lockout/Tagout I certain special conditions that have
justified an exceptionally relaxed application of the
nondeiegation doctrine were absent, 938 F.2d at 1317-18, and
they are equally absent here. The standards in question affect

Incident, 1952," The Lancet, Feb. 4, 1953, at 336-38.

the whole economy, requiring a "more precise" delegation than
would otherwise be the case, see A.L.A. Schechter Poultry
Corp. v. United States, 295 U.S. 495, 553, 79 L. Ed. 1570, 55
S. Ct. 837 (1935). No "special theories" justifying vague
delegation such as the war powers of the President or the
sovereign attributes of the delegatee have been or could be
asserted. Nor is there some inherent characteristic of the field
that bars development of a far more determinate basis for
decision. (This is not to deny that there are difficulties; we
consider some below.)

EPA cites prior decisions of this Court holding that
when there is uncertainty about the health effects of
concentrations of a particular pollutant within a particular
range, EPA may use its discretion to make the "policy
judgment" to set the standards at one point within the relevant
range rather than another. NRDC v. EPA, 284 U.S. App. D.C.
136, 902 F.2d 962, 969 (D.C. Cir. 1990); American Petroleum
Inst. v. Costle, 214 U.S. App. D.C. 358, 665 F.2d 1176, 1185
(D.C. Cir. 1981); Lead Industries, 647 F.2d at 1161 (D.C. Cir.
1980). We agree. But none of those panels addressed the claim
of undue delegation that we face here, and accordingly had no
occasion to ask EPA for coherence (for a "principle," to use the
classic term) in making its "policy judgment." The latter phrase
is not, after all, a self-sufficient justification for every refusal to
define limits.

It was suggested at oral argument that EPA's vision of
its discretion in application of § 109(b)(1) is no broader than
that asserted by OSHA after a remand by this court and upheld
by this court in International Union, UAW v. OSHA
("Lockout/Tagout II"), 308 U.S. App. D.C. 368, 37 F.3d 665
(D.C. Cir. 1994). But there, in fact, OSHA allowed itself to set
only standards falling somewhere between maximum feasible
stringency and some "moderate" departure from that level. 37

App. 12

F.3d at 669. As our prior discussion should have indicated, here
EPA's formulation of its policy judgment leaves it free to pick
any point between zero and a hair below the concentrations
yielding London's Killer Fog.

The dissent argues that a nondelegation challenge
similar to this one was rejected in South Terminal Corp. v.
EPA, 504 F.2d 646 (Ist Cir. 1974), and cites that case's
language that "the rationality of the means can be tested against
goals capable of fairly precise definition in the language of
science," id. at 677. See Dissent at 2. But the action challenged
in South Terminal was EPA's adoption of a plan for ending or
preventing violations in Boston of already-established NAAQS,
not its promulgation of the NAAQS themselves. Thus, it seems
likely that the "means" were the plan's provisions--e.g., a
prohibition on most new parking in the city, see 504 F.2d at
671, and the "fairly precisely defined" goals were the NAAQS
themselves.

Where (as here) statutory language and an existing
agency interpretation involve an unconstitutional delegation of
power, but an interpretation without the constitutional weakness
is or may be available, our response is not to strike down the
statute but to give the agency an opportunity to extract a
determinate standard on its own. Lockout/Tagout I, 938 F.2d
at 1313. Doing so serves at least two of three basic rationales
. for the nondelegation doctrine. If the agency develops

determinate, binding standards for itself, it is less likely to
exercise the delegated authority arbitrarily. See Amalgamated
Meat Cutters v. Connally, 337 F. Supp. 737, 758-59 (D.D.C.
1971) (Leventhal, J., for three-judge panel). And such standards
enhance the likelihood that meaningful judicial review will
prove feasible. See id. at 759. A remand of this sort of course
does not serve the third key function of non-delegation doctrine,
to “ensure[ ] to the extent consistent with orderly governmental

administration that important choices of social policy are made

American Petroleum Inst., 448 U.S. 607, 685, 65 L. Ed. 2d
1010, 100 S. Ct. 2844 (1980) ("Benzene") (Rehnquist, J.,
concurring). The agency will make the fundamental policy
choices. But the remand does ensure that the courts not hold
unconstitutional a statute that an agency, with the application of
its special expertise, could salvage. In any event, we do not read
current Supreme Court cases as applying the strong form of the
nondelegation doctrine voiced in Justice Rehnquist's
concurrence. See Mistretta v. United States, 488 U.S. 361,
377-79, 102 L. Ed. 2d 714, 109 S. Ct. 647 (1989).

What sorts of “intelligible principles" might EPA adopt?
Cost-benefit analysis, mentioned as a possibility in
Lockout/Tagout I, 938 F.2d at 1319-21, is not available under
decisions of this court. Our cases read § 109(b)(1) as barring
EPA from considering any factor other than “health effects
relating to pollutants in the air." NRDC, 902 F.2d at 973; see
also Lead Industries, 647 F.2d at 1148; American Lung Ass'n
v. EPA, 328 U.S. App. D.C. 232, 134 F.3d 388, 389 (D.C. Cir.
1998); American Petroleum Inst., 665 F.2d at 1185 (echoing the
same themes).

In theory, EPA could make its criterion the eradication
of any hint of direct health risk. This approach is certainly
determinate enough, but it appears that it would require the
agency to set the permissible levels of both pollutants here at
zero. No party here appears to advocate this solution, and EPA
appears to show no inclination to adopt it.‘

‘A zero-risk policy might seem to imply
de-industrialization, but in fact even that seems inadequate to
the task (and even if the calculus is confined to direct risks from

App. 14

EPA's past behavior suggests some readiness to adopt
standards that leave non-zero residual risk. For example, it has
employed commonly used clinical criteria to determine what
qualifies as an adverse health effect. See Ozone Staff Paper at
59-60 (using American Thoracic Society standards to determine
threshold for "adverse health effect" from ozone). On the issue
of likelihood, for some purposes it might be appropriate to use
standards drawn from other areas of the law, such as the
familiar "more probable than not" criterion.

Of course a one-size-fits-all criterion of probability
would make little sense. There is no reason why the same
probability should govern assessments of a risk of thousands of
deaths as against risks of a handful of people suffering
momentary shortness of breath. More generally, all the relevant
variables seem to range continuously from high to low: the
possible effects of pollutants vary from death to trivialities, and
the size of the affected population, the probability of an effect,
and the associated uncertainty range from "large" numbers of
persons with point estimates of high probability, to small

pollutants, as opposed to risks from the concomitant poverty).
First, PM (at least) results from almost all combustion, so only
total prohibition of fire or universal application of some
heretofore unknown control technology would reduce manmade
emissions to zero. See PM Staff Paper at IV-1. Second, the
combustion associated with pastoral life appears to be rather
deadly. See World Bank, World Development Report 1992:
Development and the Environment 52 (1992) (noting that
"biomass" fuels (i.e., wood, straw, or dung) are often the only
fuels that "poor households, mostly in rural areas" can obtain or
afford, and that indoor smoke from biomass burning
"contributes to acute respiratory infections that cause an
estimated 4 million deaths annually among infants and
children.").

App. 15

numbers and vague ranges of probability. This does not seem
insurmountable. Everyday life compels us all to make decisions
balancing remote but severe harms against a probability
distribution of benefits; people decide whether to proceed with
an operation that carries a 1/1000 possibility of death, and
(simplifying) a 90% chance of cure and a 10% chance of no
effect, and a certainty of some short-term pain and nuisance. To
be sure, all that requires is a go/no-go decision, while a serious
effort at coherence under § 109(b)(1) would need to be more
comprehensive. For example, a range of ailments short of death
might need to be assigned weights. Nonetheless, an agency
wielding the power over American life possessed by EPA
should be capable of developing the rough equivalent of a
generic unit of harm that takes into account population affected,
severity and probability. Possible building blocks for such a
principled structure might be found in the approach Oregon
used in devising its health plan for the poor. In determining
what conditions would be eligible for treatment under its
version of Medicaid, Oregon ranked treatments by the amount
of improvement in "Quality Adjusted Life Years" provided by
each treatment, divided by the cost of the treatment.’ Here, of

‘The "quality" of various health states was determined
by poll, and medical professionals determined the probabilities
and durations of various health states with and without the
treatment in question.

Oregon was twice forced to revise its system because
the United States Department of Healti: & Human Services
determined that the original proposal and a revision violated the
Americans with Disabilities Act, 42 U.S.C. §§ 12101-12213.
The reason given for this determination was that both versions
undervalued the lives of persons with disabilities: The original
plan measured quality of life according to the attitudes of the
general population rather than the attitudes of persons with

App. 16

disabilities. See HHS, “Analysis Under the Americans with
Disabilities Act (( ADA’) of the Oregon Reform Demonstration"
(Aug. 3, 1992), reprinted in 9 Issues in L. & Med. 397, 410,
410 (1994). The revised plan ranked treatments leaving the
patient in a "symptomatic" state lower than those leaving the
patient asymptomatic, and certain disabling conditions were >
considered “symptoms.” See Letter from Timothy B. Flanagan,
Assistant Attorney General, to Susan K. Zagame, Acting
General Counsel, HHS (Jan. 19, 1993), reprinted in 9 Issues in
L. & Med. 397, 418, 421 (1994). The Department's
determination was extensively criticized when issued. See
Maxwell J. Mehlman et al., "When Do Health Care Decisions
Discriminate Against Persons with Disabilities?" 22 J. Of
Health Politics, Policy & L. 1385, 1390 (1997) (HHS's
“decision provoked a storm of disbelief and denunciation").

We take no position on whether HHS's view was
correct, or if the underlying norm also governs EPA's decisions
under § 109(b)(1). An affirmative answer, however, would not
seem to preclude use of some of Oregon's approach. The first
step would be giving appropriate weight to the views of persons
with disabilities. The second might be measuring the
seriousness of a pollution-induced health effect by the absolute
level of well-being that the effect brings about, not by the
decrease in level that the effect causes. In other words, if the
maximum well-being level is 100 and the average asthmatic
whose asthma constitutes a disability has a well-being of 80 in
the absence of air pollution (according to a measure that
appropriately considers asthmatics’ own assessments of their
condition), then a response to air pollution that reduces the
asthmatics’ well-being to 70 could be counted as an effect of
magnitude 30 (the difference from full health), rather than 10
(the difference from the level without the pollution). That
approach would ensure that effects on persons with disabilities

App. 17

course, EPA may not consider cost, and indeed may weil find
a completely different method for securing reasonable
coherence. Alternatively, if EPA concludes that there is no
principle available, it can so report to the Congress, along with
such rationales as it has for the levels it chose, and seek
legislation ratifying its choice.

We have discussed only the primary standards. Because
the secondary standards are at least in part based on those, see
Ozone Final Rule, 62 Fed. Reg. at 38,875/3-76/1; PM Final
Rule, 62 Fed. Reg. at 38,680/3, we also remand the cases to the
agency with regard to the secondary standards as well, for
further consideration in light of this opinion.

II. Other General Claims

The petitioners and amici contend that the EPA
erroneously failed to consider a host of factors in revising the
PM and ozone NAAQS. We reject each of these claims in turn.

A. Consideration of Cost in Revising Standards

As this court long ago made clear, in setting NAAQS
under § 109(b) of the Clean Air Act, the EPA is not permitted
to consider the cost of implementing those standards. See Lead
Industries, 647 F.2d at 1148 (D.C. Cir. 1980); see also NRDC,
902 F.2d at 973 (following Lead Industries in reviewing
particulate matter NAAQS); American Petroleum Inst., 665
F.2d at 1185 (same, in reviewing ozone NAAQS). The
petitioners make four unsuccessful attempts to distinguish Lead
Industries and its progeny.

were not underestimated, even in the broad sense of that term
apparently adopted by HHS.

App. 18

First, the petitioners claim that in Lead Industries we
held only that the Clean Air Act does not compel the EPA to
consider the costs of implementation in setting a NAAQS; on
the contrary, we held that the Act precludes the EPA from
doing so. See Lead Industries, 647 F.2d at 1148 ("the statute
and its legislative history make clear that economic
considerations play no part in the promulgation of [NAAQS]").

Second, that we decided Lead Industries prior to the
Supreme Court's decision in Chevron U.S.A. Inc. v. NRDC,
467 U.S. 837, 104 S. Ct. 2778, 81 L. Ed. 2d 694 (1984) does
not, as the petitioners suggest, require us to revisit the earlier
case. The Lead Industries decision was made in Chevron step
one terms, see id., as the post-Chevron progeny of Lead
Industries have made clear. See NRDC, 902 F.2d at 973
("Consideration of costs ... would be flatly inconsistent with the
statute, legislative history and case law on this point"); NRDC
v. EPA, 263 U.S. App. D.C. 166, 824 F.2d 1146, 1158-59 (D.C.
Cir. 1987) (in banc) ("Vinyl Chloride") ("Statute on its face
does not allow consideration of technological or economic
feasibility.... Congress considered the alternatives and chose to
close down sources or even industries rather than to allow risks
to health").

Third, though the petitioners are correct that in Lead
Industries we interpreted § 109(b), which governs the setting of
NAAQS, and not § 109(d), which governs the revising of
NAAQS, we can discern no legally relevant difference in the
two sections that would make Lead Industries inapplicable to §
109(d). Section 109(d)(1) directs the EPA to:

complete a thorough review of the criteria published
under section 7408 of this title and the [NAAQS]
promulgated under this section and [to] make such
revisions in such criteria and standards and promulgate

App. 19

such new standards as may be appropriate in accordance
with section 7408 of this title and subsection (b) of this
section.

42 U.S.C. § 7409(d\(1). The petitioners contend that
consideration of costs is one pertinent factor in determining
whether revision of a NAAQS is “appropriate,” but this
argument ignores the clause immediately following
“appropriate,” which incorporates § 109(b) and thereby
affirmatively precludes consideration of costs in revising
NAAQS. Section 108(b), 42 U.S.C. § 7408(b), does require the
EPA to provide the States with information on the cost of
implementing NAAQS, but the reference to § 108 does not
permit consideration of costs in setting NAA S because it
clearly relates back to the requirement that the EPA "make ...
revisions in ["the criteria published under section 7408"] ... as
may be appropriate." And insofar as the air quality criteria do
apply to the setting of NAAQS, they do so through § 109(b),
which (again) precludes the consideration of costs and which is
explicitly incorporated into § 109(d)(1). See id. § 7409(b)\(1)
(primary NAAQS to be "based on [the air quality] criteria"
issued under § 108).

Fourth, the petitioners point to § 109(d)(2), which
creates the CASAC and requires it to advise the EPA about,
among other things, "any adverse public health, welfare, social,
economic, or energy effects which may result from various
strategies for attainment and maintenance of such [NAAQS]."
Id. § 7409(d)(2)(C\(iv). Why, ask the petitioners, would the
CASAC be required to advise the EPA about these matters if
the EPA were not then supposed to consider its advice in the
course of revising the NAAQS? As above, however, the
petitioners overlook that § 109(d)(1) directs the EPA to review
and to revise, as appropriate, the air quality standards issued
under § 108 as well as the NAAQS promulgated under §

App. 20

109(b). The advice required in § 109(d)(2)(C){iv) is pertinent
only to the EPA's duty under § 108 to provide the States with
control strategy information.

B. Environmental Consequences of Implementing NAAQS

The State Petitioners argue that the EPA erred in failing
"to consider the environmental consequences resulting from the
financial impact of the [revised PM, , and ozone NAAQS] on
the federal Abandoned Mine Reclamation Fund Act." This
argument is squarely foreclosed by our decision in NRDC. In
reviewing the EPA's previous revision of the PM NAAQS, we
rejected the argument that the EPA "erred in refusing to
consider the health consequences of unemployment in
determining the primary [NAAQS] for particulate matter" and
held that "it is only health effects relating to pollutants in the air
that EPA may consider." 902 F.2d at 972-73 (emphasis in
original). Unlike the positive health venefits of ozone that we
hold (in Part III.B, below) the EPA must consider, any
detrimental health efiects resulting from the financial impact
upon the mine fund, like the health consequences of
unemployment, are traceable to the cost of complying with the
revised PM,, and ozone NAAQS and not to the presence of
those pollutants in the air.

C. The National Environmental Policy Act

In challenging both the revised PM,, and ozone
NAAQS, the State Petitioners also argue that the EPA failed to
comply with certain requirements of the NEPA. The petitioners
recognize that the Congress has exempted all actions under the
Clean Air Act, including the setting of NAAQS, from the
central requirement of the NEPA, namely, the preparation of an
Environmental Impact Statement. Compare 42 U.S.C. §
4332(2\(C)-(D) (agency must prepare EIS in all "major Federal

“ App. 21

actions significantly affecting the quality of the human
environment"), with 15 U.S.C. § 793(c)(1) ("No action taken
under the Clean Air Act shall be deemed a major Federal action
significantly affecting the quality of the human environment
within the meaning of the [NEPA]"). Nonetheless, they suggest
that the EPA is required to complete the functional equivalent
of an EIS and also to comply with other requirements in the
NEPA, see 42 U.S.C. § 4332(2)(B), (E), (G). State Petitioners’
PM Brief at 20; State Petitioners' Ozone Brief at 19. We reject
each of these suggestions.

First, the State Petitioners contend that this court has
"recognized that the [CAA], properly construed, requires the
functional equivalent of a NEPA impact statement,’ "_ id.
(quoting Portland Cement Ass'n v. Ruckelshaus, 158 U.S. App.
D.C. 308, 486 F.2d 375, 384 (1973)). Our decision in Portland
Cement, however, actually construed only "section 111 of the
Clean Air Act." By replacing these words with "[CAA]" in their
briefs, the petitioners misrepresent our interpretation of a single
section of the Clean Air Act, dealing with emission standards
for stationary sources, as an interpretation of the entire Act.
Even if the petitioners were correct, however, Portland Cement
predated, and is now superseded by, the statutory exemption in
15 U.S.C. § 793(c)(1), which the Congress added in 1974.

Second, the State Petitioners contend that a provision of
the NEPA “requires that EPA weigh ‘economic considerations.’
" The section to which the petitioners refer reads as follows:
"all agencies of the Federal Government shall ... identify and
develop methods and procedures ... which will insure that
presently unquantified environmental amenities and values may
be given appropriate consideration in decisionmaking along
with economic and technical considerations." 42 U.S.C. §
4332(2)(B). Even if this section is properly read generally to
require an agency to consider implementation costs, § 109(d){1)

App. 22

specifically prohibits the EPA from doing so. And the NEPA
provides that it shall not "in any way affect the specific
statutcry obligations of any Federal agency ... to comply with
criteria or standards of environmental quality." 42 U.S.C. §
4334(1). Therefore, § 4332(2)(B) cannot require the EPA to
disregard the prohibition in § 109(d)(1) upon the consideration
of costs in setting NAAQS.

The State Petitioners’ remaining arguments--that the
EPA failed to comply with two other sections of the
NEPA--fare little better. Section 4332(2)(E) requires federal
agencies to "study, develop, and describe appropriate
alternatives to recommended courses of action in any proposal
which involves unresolved conflicts concerning alternative uses
of available resources." As with § 4332(2)(B), insofar as §
4332(2)(E) can be read to require the EPA to consider the costs
of implementing NAAQS when revising those standards,
contrary to the prohibition in § 109(d)(1), § 4334(1) prevents it
from having any effect.

If, on the other hand, § 4332(2)(E) is understood in the
context of the Clean Air Act to require the EPA merely to
discuss implementation alternatives, then it, like the similar §
4332(2)G) with which the petitioners also claim the EPA failed
to comply, is the functional equivalent of § 108(b)(1). That
section requires the EPA to provide the States with, among
other things, "such data as are available on available technology
and alternative methods of prevention and control of air
pollution." As we recognize with regard to the requirement that
the agency prepare an EIS, “compliance with NEPA's ...
requirements has not been considered necessary when the
agency's organic legislation mandates procedures for
considering the environment that are ‘functional equivalents’ of
the [NEPA's] process." Izaak Walton League of Am. v. Marsh,
210 U.S. App. D.C. 233, 655 F.2d 346, 367 n.51 (1981). The

App. 23

rationale for the functional equivalence doctrine is the
well-established principle that a "general statutory rule usually
does not govern unless there is no more specific rule." Green v.
Bock Laundry Mach. Co., 490 U.S. 504, 524, 104 L. Ed. 2d
557, 109 S. Ct. 1981 (1989); see also Alabama ex rel.
Siegelman v. EPA, 911 F.2d 499, 504-05 (11th Cir. 1990)
(citing cases). The NEPA is the general statute requiring
agencies to consider environmental harms, whereas the Clean
Air Act is the more specific and its equivalent provisions apply
in place of those in the NEPA. See Portland Cement, 486 F.2d
at 386 (finding functional equivalence when more specific
statute strikes "workable balance between some of the
advantages and disadvantages of full application of NEPA").

Our analysis of the petitioners' contentions leads us to
conclude that nothing in the NEPA requires the EPA in setting
NAAQS to consider or to discuss matters that the Clean Air Act
does not already permit or require.

D. The Unfunded Mandates Reform Act

The State Petitioners in the particulate matter case and
Congressman Bliley in the ozone case both contend that the
EPA is required by the Unfunded Mandates Reform Act, 2
U.S.C. § 1501 et seq., to prepare a Regulatory Impact Statement
(RIS) when setting a NAAQS, see id. § 1532, and to choose the
least burdensome from a range of alternative permissible
NAAQS, see id. § 1535. Even if the petitioners and the amicus
are correct regarding the interaction of the UMRA and the
CAA--a point the EPA strongly contests-we can provide them
with no relief. See id. § 1571(a)(3) ("The inadequacy or failure
to prepare [a RIS] ... shall not be used as a basis for staying,
enjoining, invalidating or otherwise affecting [an] agency
rule"); id. § 1571(b) ("Except as provided in [ § 1571(a), which
does not mention § 1535,] ... any compliance or noncompliance

App. 24

with the provisions of this chapter ... shall not be subject to
judicial review; and no provision of this chapter shall be
construed to [be] ... enforceable by any person in any ... judicial
action").

The State Petitioners, recognizing the limitations upon
judicial review in § 1571, contend that the EPA's failure to
prepare a RIS can nonetheless render the NAAQS arbitrary and
capricious, see 42 U.S.C. § 7607(d)(9), relying upon Thompson
v. Clark, 239 U.S. App. D.C. 179, 741 F.2d 401 (D.C. Cir.
1984). In that case, we interpreted a statute that, like the
UMRA, both specified that the RIS be included in the record
for judicial review and precluded judicial review of an agency's
compliance with the RIS requirement. We held that a
"reviewing court will consider the contents of the [RIS], along
with the rest of the record, in assessing not the agency's
compliance with the [requirement to prepare the RIS], but the
validity of the rule under other provisions of law." 741 F.2d at
405. No information in a RIS, however, could lead us to
conclude that the EPA improperly set the PM and ozone
NAAQS; the only information such a statement would add to
the rulemaking record for a NAAQS would pertain to the costs
of implementation, see 2 U.S.C. § 1532(a), and the EPA is
precluded from considering those costs in setting a NAAQS.
Accordingly, the failure to prepare a RIS does not render the
NAAQS arbitrary and capricious.

E. The Regulatory Flexibility Act

In both the ozone and particulate matter cases, the Small
Business Petitioners argue that the EPA improperly certified
that the revised NAAQS would not have a significant impact
upon a substantial number of small entities. The Regulatory
Flexibility Act, 5 U.S.C. § 601 et seq., as amended in 1996 by
the Small Business Regulatory Enforcement Fairness Act, Pub.

App. 25

L. No. 104-121, tit. II, 110 Stat. 857-74 ("SBREFA"), requires
an agency, when engaging in notice and comment rulemaking,
to "prepare and make available for public comment an initial
regulatory flexibility analysis... [that] describes the impact of
the proposed rule on small entities," 5 U.S.C. § 603(a),
including small businesses, small organizations, and small
governmental jurisdictions, see id. § 601(6). When
promulgating a final rule, an agency must describe "the steps ...
taken to minimize the significant economic impact on small
entities." Id. § 604(a)(S). According to the petitioners, if the
EPA had complied with the RFA, it would likely have
promulgated less stringent PM and ozone NAAQS than those
actually chosen, which would have reduced the burden upon
small entities.

A regulatory flexibility analysis is not required,
however, if the agency "certifies that the rule will not, if
promulgated, have a significant economic impact on a
substantial number of small entities." Id. § 605(b). Further, the
SBREFA made no change in the requirement that a regulatory
flexibility analysis conducted pursuant to the RFA include
estimates of "the number of small entities to which the
proposed rule will apply" and of "the classes of small entities
which will be subject to the requirement." 5 U.S.C. §
603(b)(3)-(4). We have consistently interpreted the RFA, based
upon these sections, to impose no obligation upon an agency
"to conduct a small entity impact analysis of effects on entities
which it does not regulate." Motor & Equip._Mfrs. Ass'n v.
Nichols, 330 U.S. App. D.C. 1, 142 F.3d 449, 467 & n.18
(1998).

The EPA certified that its revised NAAQS will "not
have a significant economic impact on small entities within the
meaning of the RFA." PM Final Rule, 62 Fed. Reg. at 38,702/2;

Ozone Final Rule, 62 Fed. Reg. at 38,887/2-3. According to the

App. 26

EPA, the NAAQS themselves impose no regulations upon
small entities. Instead, the several States regulate small entities
through the state implementation plans (SIPs) that they are
required by the Clean Air Act to develop. See 42 U.S.C. §
7410. Because the NAAQS therefore regulate small entities
only indirectly--that is, insofar as they affect the planning
decisions of the States--the EPA concluded that small entities
are not "subject to the proposed regulation." See Mid-Tex Elec.
Coop., Inc. v. FERC, 249 U.S. App. D.C. 64, 773 F.2d 327, 342
(D.C. Cir. 1985); see also 773 F.2d at 343 ("Congress did not
intend to require that every agency consider every indirect
effect that any regulation might have on small businesses in any
stratum of the national economy.").

The EPA's description of the relationship between
NAAQS, SIPs, and small entities strikes us as incontestable.
The States have broad discretion in determining the manner in
which they will achieve compliance with the NAAQS. The
EPA "is required to approve a state plan which provides for the
timely attainment and subsequent maintenance of ambient air
standards” and cannot reject a SIP based upon its view of "the
wisdom of a State's choices of emission limitations," Train v.
NRDC, 421 U.S. 60, 79, 95 S. Ct. 1470, 43 L. Ed. 2d 731
(1975) (emphasis in original), or of the technological
infeasibility of the plan. See Union Elec. Co. v. EPA, 427 U.S.
246, 265, 49 L. Ed. 2d 474, 96 S. Ct. 2518 (1976). Therefore,
a State may, if it chooses, avoid imposing upon small entities
any of the burdens of complying with a revised NAAQS. Only
if a State does not submit a SIP that complies with § 110, 42
U.S.C. § 7410, must the EPA adopt an implementation plan of
its own, which would require the EPA to decide what burdens
small entities should bear. The agency has stated, however, that
it will do a regulatory flexibility analysis before adopting an
implementation plan of its own, as it did in 1994 when
proposing such a plan for Los Angeles. See Ozone Final Rule,

App. 27

62 Fed. Reg. at 38,891/1; PM Final Rule, 62 Fed. Reg. at
38,705/3.

The responses of the Small Business Petitioners do not
persuade us to reject the EPA's argument or to deviate from our
holdings in Mid-Tex and its progeny. First, the Small Business
Petitioners contend that we must defer to the Small Business
Administration's interpretation of the Act, as expressed in a
letter to the EPA from the SBA's Chief Counsel for Advocacy,
that the NAAQS do impose requirements upon small entities.
The SBA, however, neither administers nor has any
policymaking role under the RFA; at most its role is advisory.
See, e.g., 5 U.S.C. §§ 601(3), 602(b), 603(a), 605(b), 609(b)(1),
612. Therefore, we do not defer to the SBA's interpretation of
the RFA. See Scheduled Airlines Traffic Offices, Inc. v.
Department of Defense, 318 U.S. App. D.C. 347, 87 F.3d 1356,
1361 (D.C. Cir. 1996) (no Chevron deference owed to agency
interpretation of statute it does not administer). Nor do we defer
to the EPA's interpretation of the RFA, for it does not
administer the Act either. We do, however, find the EPA's

interpretation of the statute persuasive.

Second, the Small Business Petitioners argue that the
EPA cannot claim both that the NAAQS will have no effect
upon small entities and that it will have positive health effects.
Clearly, however, the EPA can maintain that the NAAQS will
have health effects because the Clean Air Act empowers the
agency to ensure that such benefits accrue; and it can maintain
that the NAAQS will not directly affect small entities because
it has no authority (short of imposing its own implementation
plan upon a non-complying state) to impose any burdens upon
such entities.

Third, the Small Business Petitioners attempt to
distinguish the possible effects upon small entities in this case

App. 28

from the indirect effects that, as we found in Mid-Tex, are not
within the contemplation of the RFA. But Mid-Tex is not so
easily distinguished. The petitioners in that case argued that the
RFA required the FERC to consider economic effects not only
upon regulated industries but also upon the small entities that
are their wholesale customers, even though the customers were
not directly regulated by the FERC. We rejected that argument,
finding a "clear indication" in the language of § 603 that the
RFA is “limited to small entities subject to the proposed
regulation." Mid-Tex, 773 F.2d at 342; see also Motor & Equip.
Mfrs. Ass'n, 142 F.3d at 467 n.18 ("The RFA itself
distinguishes between small entities subject to an agency rule,
to which its requirements apply, and those not subject to the
rule, to which the requirements do not apply."); United
Distribution Cos. v. FERC, 88 F.3d 1105, 1170 (1996)
(regulatory flexibility analysis provision applies only to "small
entities that are subject to the requirements of the rule")
(emphasis in original). That the Clean Air Act requires the
States to submit SIPs that will achieve compliance with the
NAAQS does not, in view of the States’ nearly complete
discretion to determine which entities will bear the burdens of
a revised NAAQS, make such small entities as the SIPs may
regulate any more subject to the EPA's regulation than were the
wholesalers in Mid-Tex subject to regulation by the FERC.

Finally, the Small Business Petitioners suggest that the
Congress in enacting the SBREFA overruled our prior
interpretation of the RFA in Mid-Tex and its progeny. The
SBREFA made a number of changes in the RFA, but it did not
change anything in § 603 upon which we relied in Mid- Tex.
And although the Congress made a slight modification in §
605(b), we do not understand it to alter our analysis in
Mid-Tex. Prior to 1996, § 605(b) required an agency to provide
"a succinct statement explaining the reasons" for its
certification that the promulgated rule would not have a

App. 29

significant economic impact upon small entities. That section
now requires "a statement providing the factual basis for such
certification.” Our decision in Mid-Tex contemplates that an
agency may justify its certification under the RFA upon the
"factual basis" that the rule does not directly regulate any
small entities. Nothing in the change to § 605(b) suggests that
basis for certification is no longer permissible. (Indeed, the
section of the statute amending § 605(b) is labeled "Technical
and Conforming Amendments," see SBREFA § 243, 110
Stat. at 866.) We therefore conclude that the EPA properly
certified that its NAAQS would not have a significant impact
upon a substantial number of small entities.

III. Ozone
A. Subpart 2 and the Revised Ozone Standard

In 1990 the Congress substantially revised the Clean
Air Act by, among other things, adding specific enforcement
provisions for carbon monoxide, particulate matter, sulfur
oxides, nitrogen dioxide, lead, and as pertinent here, ozone.
Previously, the Act required that all areas of the country not
attaining the primary ozone standard, no matter how far from
attainment, come into compliance "as expeditiously as
practicable but not later than December 31, 1987." 42 U.S.C.
§ 7502 (1988). Many areas had not attained the primary
ozone NAAQS by that date; some were still a long way from
doing so. The Congress responded to the continued ozone
problem by enacting a new enforcement scheme, which it
codified as Subpart 2 of Part D of the Clean Air Act, 42
U.S.C. §§ 7511-7511f, redesignating the original provisions
as Subpart 1.

Subpart 2 requires the EPA to classify nonattainment
areas based upon their design value, which is a rough measure
of whether an area complies with the 0.12 ppm, 1-hour primary

*More specifically, the design value is the fourth-highest |
daily maximum ozone concentration in an ‘area over three |
consecutive years for which there are sufficient data. If that ;
value is less than or equal to 0.12 ppm, then an area will have
only three expected values above that level and it will be in
attainment with the ozone NAAQS. See EPA, The Clean Air
Act Ozone Design Value Study: Final Report 1-1 to 1-22
(1994) (filed pursuant to 42 U.S.C. § 7511b(g), which required
the EPA to conduct "a study of whether the [existing design
value] methodology ... provides a reasonable indicator of the
ozone air quality of ozone nonattainment areas"; the EPA
concluded it did).

U.S.C. § 7511(aX(1):

Moderate . . .0.138 up to 0.160... 6 years after November 15, 1990

Extreme ...0.280 and above ... . 20 years after November 15, 1990

The Severe Area category is later subdivided, creating a sixth
classification for ozone nonattainment areas. See id. §
7511(aX(2) (“Notwithstanding table 1, [for] a severe area with
a 1988 ozone design value between 0.190 and 0.280 ppm, the

App. 31

extreme, and provides an attainment date for each class. See id.
§ 7511(a)(1)-(2). Subpart 2 also specifies, for each class of
nonattainment areas, both measures that the States must take to
reduce emissions of the chemicals that are precursors of ozone
and information that the States must report to the EPA. See id.
§ 751 1a. In short, Subpart 2 is the Congress's comprehensive
plan for reducing ozone levels throughout the country.

The State and Non-State Petitioners, along with
Congressman Bliley appearing as an amicus curiae, argue that
Subpart 2 precludes the EPA from revising the primary and
secondary ozone NAAQS. We reject this argument (in Part
III.A.1) insofar as it pertains to the EPA's continued ability to
promulgate a revised ozone NAAQS or to designate areas as
not in attainment with a revised NAAQS. We agree (in Part
III.A.2) with those petitioners, however, insofar as they
maintain, based upon the text and structure of Subparts | and 2,
that the EPA is precluded from enforcing a revised primary
ozone NAAQS other than in accordance with the
classifications, attainment dates, and control measures set out
in Subpart 2. Further, we conclude (in Part III.A.3) that the
EPA ay not require a State to comply with a revised
secondary ozone NAAQS in any area that has yet to attain the
0.12 ppm primary standard.

1. The EPA's Power to Revise the Ozone
NAAQS and Designate Areas as Nonattainment

The 1990 amendments did not alter the section of the
Clean Air Act that provides for setting and revising primary and
secondary NAAQS. See 42 U.S.C. § 7409. The Administrator,
therefore, still must "at five-year intervals [from December 31,
1980] ... complete a thorough review of ... the [NAAQS]

attainment date shall be 17 years ... after November 15, 1990").

App. 32 ,

promulgated under this section and ... make such revisions in
such ... standards ... as may be appropriate." Id. § 7409(d)(1).
The Second Circuit held that this section continues to "set[ ]
forth a bright-line rule for agency action," American Lung
Ass'n v. Reilly, 962 F.2d 258, 263 (1992), and we agree.
Nothing in the Act modifies this "bright-line rule” or otherwise
makes it inapplicable to revision of the ozone NAAQS. ;

To the extent that the 1990 amendments shed any light
upon this question, they suggest that the EPA retains its
authority to revise the ozone NAAQS. For example, if the EPA
relaxes a NAAQS after enactment of the 1990 amendments,
then "the Administrator shall ... promulgate requirements
applicable to all areas which have not attained that [relaxed]
standard as of the date of such relaxation.... [which] shall
provide for controls ... not less stringent than the controls
applicable to areas designated nonattainment before such
relaxation." 42 U.S.C. § 7502(e). Although two other
subsections of § 172 are expressly made inapplicable to the
ozone regulations in Subpart 2, see id. § 7502(a)(1)(C),
(aX(2\(D), thi
