SUPREME COURT OF THE UNITED STATES
AMERICAN TRUCKING ASSN'S, INC. et al.,
BROWNER, EPA ADMIN.,
On Writ of Certiorari to the
United States Court of Appeals
for the District of Columbia Circuit
BRIEF OF AMICUS CURIAE MERCATUS CENTER
IN SUPPORT OF CROSS-PETITIONER
2dedicated to advancing knowledge of administrative regulations and their effects on society. Through its Public Interest Comment project, RSP submits independent analyses of proposed rules in agency rulemaking proceedings. It filed two such analyses with EPA on the proposed national ambient air quality standards for ozone and particulate matter during the comment period. Those comments focused on the inadequacy of the scientific and economic foundation of the proposed standards, the failure of EPA to consider offsetting health risks and the disproportionate costs that would be incurred in implementing the standards. Each is central to the issue of the petition herein.
3Costle, 665 F.2d 1176, 1185 (D.C. Cir. 1981), cert. denied sub nom. American Petroleum Inst. v. Gorsuch, 455 U.S. 1034 (1982), including indirect health effects such as "costs associated with alleged health risks from unemployment." NRDC v. EPA, 902 F.2d 962, 973 (D.C. Cir. 1990), vacated in part, 921 F.2d 326 (D.C. Cir.), cert. dismissed sub nom. Alabama Power Co. v. NRDC, 498 U.S. 1075 (1991).
This unduly narrow reading of § 109 is not supported by the CAA's text, purpose, context, structure or legislative history�or by common sense. It is, moreover, inconsistent with the D.C. Circuit's reading of a significant part of §112(b)(1)(B) of the CAA, 42 U.S.C. § 7412(b)(1)(B), which established the boundaries for hazardous pollutants "at the level which in the [Administrator's] judgment provides an ample margin of safety to protect the public health." In NRDC v. EPA, 824 F.2d 1146 (D.C. Cir. 1987) (en banc) ("Vinyl Chloride"), the D.C. Circuit read § 112 as requiring an EPA finding of "significant risk," id. at 1153, and as permitting consideration of non-health as well as compliance costs and related matters in setting the emissions standards. Id. at 1158, 1163-66. Thus, had the open-ended measure of standard setting approved in Vinyl Chloride been adopted by EPA and the D.C. Circuit in the instant case (rather than the health restricted test of Lead Industries), it is unlikely that this case or its companion, Docket No. 99-1257, would be before the Court. That is, under that test, EPA's discretion would not have been largely unconfined, the requirements of the nondelegation doctrine could have been satisfied, and a NAAQS standard that properly took into account all relevant factors, including implementation costs, could have been adopted.2
4These issues of statutory construction under § 109 are persuasively addressed in Cross-Petitioners' brief and we endorse but do not repeat that analysis here.3 Our focus instead is on the effect of EPA's misguided reading of the clause in § 109�that NAAQS levels for ozone and particulate matter must "protect the public health" with an "adequate margin of safety." Because EPA's reading excludes consideration of important countervailing health and welfare considerations (e.g., implementation costs as well as direct and indirect health and welfare effects), the revised NAAQS are unlikely to improve public health and welfare. We examine the public health and welfare effects of different decision rules that could be applied if EPA were not constrained by Lead Industries, and show that these alternative decision rules would better meet the statutory directive of protecting public health with an adequate margin of safety.
the kind of analytical support required for these EPA rules. See Merriam- Webster's Collegiate Dictionary 61 (Deluxe ed. 1998) ("ample" is something "more than adequate").
5The revised NAAQS rules at issue here represent a major departure by EPA. Its prior standard for PM regulated all particles larger than 10 microns; the revised standard expands that regulatory scope by including fine particles of soot down to 2.5 microns, which "are so small that several thousand of them could fit on the type-written period of the end of a sentence." Statement of EPA Administrator Carol M. Browner before Senate Subcommittee on Clean Air, Wetlands, Private Property & Nuclear Safety of the Comm. on Environment & Public Works, 105th Cong., 1st Sess. 280 (Feb. 12, 1997). The new rule generally retains the 1987 standards for particulate matter larger than 10 microns (PM10) but creates a new standard for fine particles larger than 2.5 microns (PM2.5). The PM2.5 standard specifies a maximum annual average concentration of 15 and a daily maximum of 65 micrograms per cubic meter, summarized as 15/65 µg/m3. The previous ozone standard applied to concentrations of .12 parts per million (ppm) averaged over one hour; the new rule sets it at .08 ppm averaged over eight hours which constitutes roughly a 10 percent reduction.4 While implementation cost estimates are necessarily imprecise, responsible reviewers put total annual compliance costs for the two standards between $46.3 billion (EPA's estimate) and $210 billion (Reason Public Policy Institute upper bound estimate); the Mercatus Center estimated implementation costs to be at least $100 billion annually. See discussion pp. 19 n.14, 20 & 22 n.16 infra.
EPA acknowledged that its selection of ozone and PM levels�at .08 ppm for ozone and 15/65 µg/m3 for PM2.5� was not based on scientific evidence establishing a safe threshold for ozone or PM health effects. Indeed, the announced standards start from the assumption that there is
6no safe threshold below which ozone and PM would not pose adverse health effects.5 EPA therefore relied upon a "linear, nonthreshold dose-response model" to evaluate the benefits of each further reduction in ozone and PM.6 However, under this model, each further reduction in ozone and PM will be found to improve public health (i.e., provide life-saving benefits) no matter how "clean" the air already may be. Thus, there is no standard above zero that could be said to be "safe" or said not to cause adverse health effects.
Nonetheless, EPA did not set either standard at zero. It understood, at least implicitly, that zero concentration levels were technically infeasible, and that even if achievable, such standards would impose severe economic and other costs that dwarfed all possible benefits. American Trucking Ass'ns, Inc. v. EPA, 175 F.3d 1027, 1038 & n.4 (D.C. Cir. 1999). Fettered by Lead Industries, however, EPA could not assert that the costs of setting the standards at zero would outweigh their benefits.7 EPA did not explain how or why it selected
6 The linear, nonthreshold dose-response model that EPA used to support its analysis relates the predicted change in health effects to a change in the concentration of PM or ozone. Unlike other chemicals regulated by EPA under this section of the CAA, EPA has no scientific evidence of a threshold concentration below which PM or ozone will not have health effects. This is the nonthreshold aspect of the model. The linear aspect of the model assumes that regardless of the overall concentration of ozone or PM to which an individual is exposed, a one unit change in that concentration will have the same marginal effect on public health.
7 We use the terms "costs" and "benefits" here in their broadest senses and include among them "risk" and "cost-benefit" analyses as well as "wealth-health" and "health-health" effects (discussed pp. 12-23 infra).
7the .08 ppm (ozone) or 15/65 µg/m3 (PM2.5) levels as compared with any other levels, and thus it did not identify a principled basis for determining what concentrations of ozone and PM in the atmosphere are adequate to protect public health. This narrowly constrained decision structure, which did not consider trade-offs between different health effects, the cost of implementing a standard, or the health effects of large compliance costs, conflicts with CAA § 101(b). That section expressly identifies "promot[ing] the public health and welfare and the productive capacity of its population" as one of the primary purposes of the Clean Air Act. 42 U.S.C. § 7401(b)(1).
Confined by Lead Industries, EPA was forced to produce an alternative, non-cost basis for the new ozone and PM levels. As that alternative, it chose unbridled and essentially unreviewable administrative discretion, asserting that selecting the "adequate margin of safety" was "a policy choice left specifically to the Administrator's judgment." Ozone Rule, 62 Fed Reg. at 38,857; see also PM Rule, 62 Fed. Reg. at 38,653. Thus, according to EPA, it is free under CAA § 109 to select any point along a dose-response continuum and claim that this point provides an adequate margin of safety without regard to whether that margin could be satisfied at a less stringent level or whether a more stringent level was necessary.
8quality concentration levels established by the standards were justified. See, e.g., Letter from Frank E. Kruesi, Assistant Secretary for Transportation Policy, to Sally Katzen, Office of Information and Regulatory Affairs, Office of Management and Budget (Nov. 20, 1996)("It appears incomprehensible that the Administration would commit to a new set of standards and new efforts to meet such standards without much greater understanding of the problem and its solutions.").
9id. at 38,864, but also the effects were temporary and reversible. More importantly, these studies did not examine effects at levels lower than the proposed new standard of .08 ppm, and EPA did not distinguish between lung function effects at .08 ppm and higher levels. Id. at 38,863-64.
Nor were these gaps filled by epidemiological studies. In evaluating the effects of ozone, EPA reviewed studies correlating high ozone concentrations and above normal hospital admissions. Id. at 38,864. But as EPA admits, these ozone hospital admissions only "represent a small fraction of the total respiratory-related hospital admissions for asthmatics" and provide no support for the particular ozone standards of .08 because the studies report "no discernable threshold at or below this level." Id. Long-term laboratory animal studies referenced by EPA did not fill this gap. While subsequent dissection revealed changes in the biochemistry and structure of the lungs, the animal studies showed no change in behavior or function of the lungs at exposures significantly higher than .08 ppm (.5 ppm to 1.0 ppm). 61 Fed. Reg. 65,715, 65,721 (Dec. 13, 1996). Indeed, at the lowest exposure level examined of .12 ppm, animal studies showed no effects at all. Id.
The issue here is not whether there is scientific evidence to support restrictions on ozone, but rather the absence of any evidence showing why the .08 ppm standard is a correct or reasonable level, or why a lower or higher level is not better. Because of Lead Industries, EPA was not forced to provide comparative evidence or consider other health or cost effects that reduced the identified benefits from the new standard or that offered a basis for a selected stopping point. This unfocused state of the supporting evidence is even more significant because EPA's highly regarded Clean Air
10Scientific Advisory Committee ("CASAC")8 did not endorse the .08 ppm ozone standard. In giving advice to the EPA Administrator, the CASAC explained that "there is no 'bright line' which distinguishes any of the proposed standards (either the level or the number of allowable exceedances) as being significantly more protective of public health" than the existing standard. CASAC Letter to Carol Browner re: Ozone (November 30, 1995) in Ozone JA 238.9
9 CASAC concurred (unanimously) that a measure of ozone that focused on concentrations over an 8-hour period would be more appropriate than the prior standard which measured concentrations over a 1-hour period. EPA states that the prior standard of .12 ppm measured over 1 hour is equivalent to a standard of .09 ppm measured over 8 hours.
11questions and uncertainties" left open by EPA's supporting evidence�e.g., which fine particles are hazardous, how to interpret observed correlations between health effects and PM�and concluded that it was impossible to rely upon health effects as the sole basis for selecting any standard. EPA was unable to identify the sources of particulates which would need to be controlled if its regulations are to have any beneficial effects on public health. The prepared statement of CASAC Chair Dr. Wolff explained the problem:
PM10 and PM2.5 . . . are composed of four or five major constituents and hundreds of trace constituents . . . . The causative agent [of adverse public health effects] could be some constituent of the PM rather than the total PM or total PM2.5 which would require a control strategy targeted at the causative constituent rather than at PM10 or PM2.5 in general. . . . There is no biologically plausible mechanism that could explain the apparent relationship between acute mortality and PM at concentrations that are a fraction of the present PM10 NAAQS. (Id. at 92-93.)
In brief, EPA's official science advisors concluded with near unanimity that the agency had not obtained critical missing support for the level of its PM2.5 rule. See CASAC Letter, PM JA at 3165 ("[t]he Panel is unanimous . . . in its desire to avoid being in a similar situation [of too little data with too little time to evaluate and integrate it] when the next PM NAAQS review cycle is under way by a future CASAC Panel").
12quandary as to how to develop and support particular levels without being forced to select a zero standard. EPA clearly considered tradeoffs when it chose to set a non-zero standard, but it was not allowed to consider those trade-offs openly or to use all the tools required for rational decision making. If a reduction in ozone has harmful side effects (e.g., reducing the protection from ultraviolet rays, see pp.15-17 infra), that information is critical in deciding whether and where to set the standard. If the cost of reducing ozone and small particles includes an increase in the number of asthma cases and more deaths than lives saved, particularly among vulnerable groups such as the urban poor, see pp. 17-19 infra, that information should encourage setting the standard at a level that can be achieved at more reasonable cost. How EPA's decision is made�and, in particular, what information can be considered and relied upon�is critical to whether the CAA's objective of both improving public health and increasing productive capacity will be achieved. 42 U.S.C. § 7401(b)(1).
13analysis�were not included. See generally Susan E. Dudley & Wendy L. Gramm, EPA's Proposed Ozone Standard May Harm Public Health and Welfare, 17 Int'l J. Risk Analysis 403 (1997); Edward W. Warren & Gary E. Marchant, "More Good Than Harm": A First Principle for Environmental Agencies and Reviewing Courts, 20 Ecol. L. Q. 379 (1993); cf. Presidential/Congressional Commission on Risk Assessment and Risk Management, Framework for Environmental Health Risk Management, vol. I at 38 (1997).
As the lower court demonstrated, EPA could have relied upon a determinate decision rule that would eradicate "any hint of direct health risk" by setting NAAQS levels at zero for ozone and PM. 10 Cert. Pet. App. (Docket No. 99-1257) at 15a. But such a rule requiring "deindustrialization" was rejected out of hand by EPA. As a consequence, EPA was left with no guiding decision standard other than the Administrator's subjective "policy judgment." 62 Fed. Reg. at 38,869 (ozone rule); id. at 38,691 (PM rule); see also Testimony of George T. Wolff, supra at 17. This, the lower court said, would violate the constitutional requirement that the NAAQS standards set by EPA be based on some determinate decision rule. Cert. Pet. App. (Docket No. 99- 1257) at 6a. The court further noted that "[e]veryday life compels us all to make decisions balancing remote but severe harms against a probability distribution of benefits," id. at 16a, and suggested that EPA could develop a "generic unit of harm" and determine how many such units are permissible under the CAA in setting NAAQS standards. Id.
By definition, the balancing decisions made in everyday life involve weighing the positive consequences of an action against the negative consequences. Applied here, such a
14balancing would require that all factors be considered, not just the negative health effects of pollutants in the air. To guide that judgment the CAA should be read as permitting cost-benefit analysis. Cost-benefit is merely a "regulatory method that calls for regulators to identify, and make relevant for purposes of decision, the good effects and the bad effects of regulation, and to quantify those as much as possible in terms of both dollar equivalents and life-years saved, hos- pital admissions prevented, workdays gained, and so forth." Cass R. Sunstein, Cognition and Cost-Benefit Analysis p. 9, Univ. Chi. Law & Economics Working Paper No. 85 (2d. Series) (October 1999) (forthcoming J. Legal Studies) <http://www.law.uchicago.edu/Publications/Working/index.html>. 11 Indeed, former EPA officials acknowledge that the use of benefit-cost analysis at the beginning of the regulatory process has led to significantly increased benefits and reduced costs in the affected regulations. See Richard D. Morgen- stern, Economic Analyses at EPA: Assessing Regulatory Impact 2-3, 473-74 (Resources for the Future 1997) (former Associate Assistant Administrator, EPA Office of Policy Analysis).
Only by balancing the positive benefits of reducing ozone and PM against offsetting negative consequences of achieving those reductions can EPA find an "intelligible principle" on which to base its standards. This section offers several balancing criteria applicable in that process. It begins with health criteria and goes on to examine increasingly broad decision rules to conclude that the statutory goals
15protecting public health and welfare are best promoted with an open balancing of benefits and costs.
Had EPA engaged in a more complete analysis, it seems clear that it would have been obliged to set the ozone standard at a different level. 12 In estimating the effects and deciding the appropriate levels of permissible ozone concentrations, EPA explicitly disregarded its own evidence as well as evidence presented by other agencies that reducing ground-level ozone to the EPA levels could reduce ozone's screening effect on harmful ultraviolet-B ("UV-B") radiation and lead to thousands of additional skin cancer and cataract cases per year. See EPA, Calculations of the Impact of Tropospheric Ozone Changes on UV-B Flux and Potential Skin Cancers (Draft)(September 1994)(Cupitt, Larry T.) in Ozone JA 3089-3104; Randall Lutter & Christopher Wolz,
16UV-B Screening by Tropospheric Ozone: Implications for the National Ambient Air Quality Standard, Environmental Science & Technology, Vol. 31, No. 3 (1997). For example, evidence in the record submitted by the Department of Energy projected that a .01 ppm reduction in ozone concentrations, as required by EPA's ozone rule, would result in 25 to 50 additional melanoma-caused fatalities, 130-260 additional incidences of cutaneous melanoma, 2,000-11,000 additional cases of non-melanoma skin cancer, and 13,000- 28,000 additional incidences of cataracts each year. Statement of Marvin Frazier, DOE Office of Health & Environmental Research, Before CASAC (March 21, 1995) in Ozone JA 258-59. Critically, these negative results from lowered ozone concentrations dwarfed EPA's projected positive health effects. Since none of the evidence reviewed by EPA's science advisors suggested that implementation of EPA's stricter ozone rule would reduce human fatalities, the loss of protective health benefits from current ozone levels under the new rules would outweigh any health benefits that could be gained from reduced ozone levels. See Susan E. Dudley & Wendy L. Gramm, supra at 404:
[The Department of Energy's analysis] suggests the rule will induce 25-50 more fatalities each year (since EPA's best estimate of the health benefits of the new standard do not include any reduced fatalities). To compare the morbidity effects, we used EPA approaches to convert health effects to dollars. We estimate that the negative health impacts from this rule will exceed EPA's best estimate of the positive health effects by over $300 million per year.
Particulate matter also serves a beneficial screening function against harmful UV-B radiation, although these benefits, by themselves, do not outweigh the positive health effects resulting from reductions in PM. Nonetheless, it is unsound public policy and contrary to the CAA's requirements to ignore the positive health effects of PM in
17setting a standard designed to protect public health with an adequate margin of safety. But that appears to be how EPA proceeded here because of Lead Industries.
In its Advance Notice of Proposed Rulemaking for the Ozone and PM standards 61 Fed. Reg. 65,764, 65,768 (Dec. 13, 1996), EPA described another unwelcome side effect of reducing PM. It cautioned that "a reduction of a fine particle precursor possibly can increase ozone or increase a different fine particle component (e.g., SOx reductions leading to increased ammonium nitrate or NOx reductions increasing sulfate formation)." In other words, EPA recognized that the reduction of fine particles as required by its PM2.5 NAAQS standard could increase emissions of other pollutants that may have harmful health effects.
While consideration of health-health tradeoffs increases the likelihood that public health will, on balance, be protected, this methodology does not identify any specific standard (or "intelligible principle"). For example, if the dose-response function for both the beneficial UV-B effects and the detrimental ozone or PM health effects are linear, and do not exhibit a threshold, then a health-health decision rule will drive the standard to zero in order to minimize levels of the pollutant if the detrimental effects dominate (as may be the case for PM) or lead EPA not to regulate the pollutant at all if the beneficial effects dominate (as may be the case for ozone). Nonetheless, considering offsetting direct health costs associated with a rule is essential if EPA is to optimize public health.
18EPA rules and of their effect on disposable family income. A body of research indicates that serious health problems arise when family living standards decline. See Stephen J. Breyer, Breaking the Vicious Circle: Toward Effective Risk Regulation 23 (1993) ("deprivation of real income itself has adverse health effects, in the form of poorer diet, more heart attacks, more suicides"). 13
The "wealth-health" decision rule translates such costs into statistical deaths and counsels against imposing regulations that are projected to cause a greater number of deaths (through lower income) than they prevent. See Randall Lutter & John F. Morrall, Health-Health Analysis: A New Way to Evaluate Health and Safety Regulation, 8 J. Risk & Uncertainty 43-66 (1994); Ralph L. Keeney, Estimating Fatalities Induced by the Economic Costs of Regulations, 14 J. Risk & Uncertainty 5 (1997). Recent studies linking income and mortality find that every $15 million decline in net income induces one statistical death. See Randall Lutter, John F. Morrall, III, & W. Kip Viscusi, The Cost-Per-Life- Saved Cutoff for Safety-Enhancing Regulations, 37 Economic Inquiry 599-608 (October 1999). The total number of additional deaths attributable to the adverse wealth effects of the ozone and PM rules ranges from 665 to 4,050 for the ozone rule and 2,447 to 10,000 for the PM rule. Against these numbers, EPA estimates that the ozone rule will prevent 350 fatalities and the PM rule another 3,300 to 16,000. In other words, 315 to 3,700 additional deaths will occur under
19the ozone rule, while more lives will be saved than lost under the PM rule. 14
This analysis emphasizes the problems inherent in narrowly constricting the factors that EPA can rely upon in shaping and approving rules under the CAA. The NAAQS regulations cannot be accurately assayed without including the positive health benefits from ozone and PM as well as the consequences of reducing consumer wealth and therefore of increasing mortality.
20well as benefits of the intended regulation. The principle is widely recognized and imbedded in agency rulemaking subject to Presidential oversight. See, e.g., Executive Order 12,866, 58 Fed. Reg. 51,735 (Sept. 30, 1993) (even though "some costs and benefits are difficult to quantify, [agencies shall] propose or adopt a regulation only upon a reasoned determination that the benefits of the intended regulation justify its costs"). A cost-benefit analysis is simply a comprehensive way of ensuring that a regulation does more good than harm. See, e.g., Kenneth J. Arrow, et al., Is There a Role for Benefit-Cost Analysis in Environmental, Health and Safety Regulation?, 272 Science 221 (1996); see also Edward W. Warren & Gary E. Marchant, supra. To deny an agency the authority to examine all benefits and costs� whether focused on economic trade-offs, comparing risks, evaluating technical requirements, analyzing feasibility, or assessing other opportunity costs�is to consign its regulations to weak and unsatisfactory justifications.
EPA did conduct a Regulatory Impact Analysis that estimated the benefits and costs of the standards (in one year, 2010), although it argued that this information was "not relevant to establishing the standards themselves." RIA at ES-3. EPA concluded that the cost of fully attaining the ozone standard would be $9.6 billion and the benefits could range from $1.5 billion to $8.5 billion in 2010. Thus, under EPA's estimate the ozone rule would impose costs in excess of benefits of between $1.1 billion and $8.1 billion per year. Meeting the PM standard in 2010, according to EPA's estimates, would cost $36.7 billion, and offer benefits ranging from $19.8 billion to $109.7 billion. RIA at 13-2. EPA thus estimated that the net effect of achieving the PM standard in 2010 could range from net costs of $18 billion to net benefits of $67 billion.
By EPA's own analysis, the ozone rule clearly fails a cost- benefit test, while the PM rule fails under certain
21assumptions. Furthermore, EPA's estimates have been criticized as overstating benefits and understating costs. The benefits figures are dominated by statistical deaths avoided which, according to EPA's approach, are valued at $4.8 million each; but this figure "significantly overstates the value most people would attach to the average number of life years saved (per person) by the [Clean Air Act]." Advisory Council on Clean Air Compliance Analysis Letter to EPA (October 23, 1996), docketed as EPA-SAB-Council- ltr-97-001 <http://www.gov/science1/coul9701.pdf>; see Na- tional Research Council, Paying Our Way: Estimating Marginal Social Costs of Freight Transportation, TRB Special Report #246, at 159 (1996) ("12 years are lost on average by a person who dies prematurely as a result of air pollution"). Furthermore, the relationship between these pollutants and mortality itself is in question. CASAC did not review the studies EPA relied upon for the ozone mortality effects, RIA 12-32, and it was concerned about "the many unanswered questions and uncertainties associated with establishing causality of the association between PM2.5 and mortality." CASAC Letter, PM JA at 3164.
EPA recognized that its cost estimates were "speculative," RIA at 13-7, because it knew of no technologies to bring many areas (at least 20% of the nation) into compliance with the standards by 2010. It overcame this by first assuming the deployment all known controls15 and then by assuming that additional emissions reductions required to attain the standards would cost $10,000 per ton. This arbitrary figure
22unrealistically assumes that the remaining residual tons of emissions can be removed as inexpensively as the earlier tons. But see Stephen G. Breyer, supra at 11 ("Remov- ing that last little bit can involve limited technological choice, high costs, devotion of considerable agency re- sources, large legal fees, and endless argument."). Other estimates place the costs of reducing the residual emissions at between $30,000 and $90,000 per ton. RPPI at 15; see also Randall Lutter, Is EPA's Ozone Standard Feasible?, AEI-Brookings Joint Center for Regulatory Studies, Regulatory Analysis No. 99-6 (December 1999) <http://www.aei.brookings.org/search/results.asp> ("meeting the standard in 2010 would cost nearly $5 trillion in one city, and $70 billion in seven other cities"). Again, had such calculations been considered as part of an explicit cost-benefit analysis, EPA would have been forced to select different NAAQS levels. 16
From a public health perspective, EPA's deliberate disregard of the costs of its NAAQS standards is a serious deficiency because costs expended on reducing levels of ozone and PM could otherwise be devoted to more beneficial purposes. The net public benefit from a broader decision- making focus can be substantial. One recent study conducted at the Harvard Center for Risk Analysis found that a reallocation of current spending from lower risk to higher risk problems could more than double the number of lives saved. See Tammy O. Tengs & John D. Graham, The Opportunity
23Cost of Haphazard Social Investments in Life-Saving, ch. 8, in Risks, Costs, and Lives Saved: Getting Better Results from Regulation (Robert Hahn, ed. 1996). Such gains are likely even when bureaucratic constraints, such as shifting funds across agencies, remain in place.
The ultimate reason, however, for reversing the Lead Industries ruling is that it misreads Congress' obvious intent when it required in § 109 that ambient air standards "protect the public health" with an "adequate margin of safety." There is nothing in these terms or anywhere else in the Clean Air Act requiring that major rules encompassing all aspects of the economy be decided by looking selectively at only some of the facts and some of the effects of the rules. Indeed, it is irrational to suggest that Congress meant for EPA to do more harm than good by its regulations. See E. Warren & G. Marchant, supra at 417-28; see also Corrosion Proof Fittings v. EPA, 947 F.2d 1201, 1221-22 (5th Cir. 1991). Similarly, Congress could not have meant that EPA was authorized to set a standard at any level based on the Administrator's "policy judgment." Direct health effects that are considered under Lead Industries are important. But without identifying how and where the benefits diminish or the costs increase, arbitrary and erroneous decisions are inevitable. It is time, in other words, to correct the long-standing mistake made in Lead Industries that imposes an irrational decision-making process on EPA that Congress never intended.
24Congress did not intend to constrain EPA's assessment of the effects of its NAAQS rules. See Chevron U.S.A., Inc. v. NRDC, 467 U.S. 837, 842-43 (1984) (no deference by court where Congressional intent is clear); accord Federal Cert. Opp. Br. (Docket No. 99-1426) at 9 (review of Lead Industries as a Chevron step one case). Since Lead Industries was a pre-Chevron case, the lower court was, within the boundaries of stare decisis, bound by that determination. See Maislin Indus., U.S., Inc. v. Primary Steel, Inc, 497 U.S. 116, 131 (1990) (once the Court has "determined a statute's clear meaning, we adhere to that determination under the doctrine of stare decisis, and we judge an agency's later interpretation of the statute against our prior determination of the statute's meaning"); Lechmere, Inc. v. NLRB, 502 U.S. 527, 537 (1992); National Fed'n of Federal Employees v. Dep't of Interior, 526 U.S. 86 (1999) ("NFFE").
However, that does not answer whether this Court or EPA should decide in the first instance what "determinate criterion" should be employed by EPA in "drawing lines" of the levels of permissible pollutants pursuant to CAA § 109. By its terms, § 109 requires consideration of the effect of the selected standards on "public health" with an "adequate margin of safety"; however, beyond that positive require- ment, § 109 does not rule out consideration of any health, wealth or cost effects. By its terms, however, § 109 provides no direct guidance on the criteria to be applied by EPA in setting standards for particular pollutant levels or for setting the parameters on how EPA's authority is confined. The circumstances here are similar to NFFE where the Court found that even though the agency's initial interpretation of the ambiguous statutory term was reasonable, the issue had to be remanded to the FLRA for reconsideration under the newly defined mandate because it may have been clouded by the erroneous reading of the D.C. Circuit. Thus, under Chevron, the matter should be remanded to EPA to reinterpret
25§ 109 under the new understanding of the factors that can be considered. See 467 U.S. at 842-43.
