Facts of the case

After the 2007 Supreme Court decision in Massachusetts v. EPA that determined that air pollution was subject to Environmental Protection Agency (EPA) regulation under the Clean Air Act, the EPA set out a series of standards governing greenhouse gas emissions. One of these benchmarks set emission standards for vehicles, while another one required stationary sources of greenhouse gases to obtain constructing and operating permits from the EPA. The petitioners, who include various state and industry groups, challenged these rules on the grounds that they were based on an improper construction of the Clean Air Act and are arbitrary and capricious because they are based on an inadequate scientific record. The U.S. Court of Appeals for the Federal Circuit dismissed the challenges.


Did the EPA permissibly determine that its regulation of greenhouse gas emissions from new motor vehicles under the Clean Air Act also triggered permit requirements for stationary sources of greenhouse gas emissions?

Justice Scalia has our opinion this morning in case 12-1146, Utility Air Regulatory Group v. EPA.

These cases are here on writ of certiorari to the United States Court of Appeals for the District of Columbia Circuit.

They involve permitting requirements that the Clean Air Act imposes on stationary sources that contribute to air pollution.

There are two different permitting programs at issue.

The first called the Prevention of Significant Deterioration Program or PSD makes it unlawful to construct or modify a major -- that's a statutory term ”major emitting facility” without a permit.

The second program found in Title V of the Act makes it unlawful to operate a “major source” without a permit.

The Act defines the major emitting facilities and major sources that are required to have permits as those who have the potential to emit any air pollutant in excessive the specific numerical thresholds set out in the statute.

Those thresholds are either 100 or 250 tons per year, depending on the program and the type of source.

A few years ago, in compliance with this Court's decisions in a case called Massachusetts versus EPA.

EPA began regulating greenhouse gases as an air pollutant when they are admitted from new motor vehicles, mobile sources.

EPA announced at that time that the Clean Air Act's permitting requirements would apply to stationary sources that emit greenhouse gases.

But EPA recognized that greenhouse gases could not sensibly be regulated under the PSD Program in Title V in the manner set forth in the Act.

As EPA explained, greenhouse gases are emitted from stationary sources in much larger quantities than conventional pollutants, not just from large industrial sources like factories and power plants, but also from schools, churches, shopping centers, offices, apartment buildings and structures of all kinds.

If a permit were required for every structure with the potential to emit greenhouse gases in excess of the 100 ton or 250 ton per year thresholds then according to EPA, the number of sources required to have PSD permits would increase from about 800 to more than 80,000, and the number required to have Title V permits would increase from fewer than 15,000 to more than 6 million.

The cost of administering the permit programs would balloon into the tens of billions of dollars and decade-long delays in issuing permits would become common plays, causing construction to grind to a halt nationwide.

But EPA came up with a simple solution to avoid these problems, it would just rewrite the statute, or as the agency more delicately put it, it would “tailor” the statute to accommodate greenhouse gases.

EPA's tailoring involved among other things, increasing the threshold at which a permit was required from this -- which a permit was required from the statutory figure of 100 or 250 tons per year to the agency's chosen figure of 100,000 tons per year.

Numerous parties including several states sought review in the D.C. Circuit which denied some of the petitions and dismissed others for lack of jurisdiction.

We granted certiorari and we now affirm in part and reverse in part.

Our analysis is divided in -- into two parts dealing with two distinct questions.

The first part is joined by the Chief Justice and Justices Kennedy, Thomas and Alito.

In this part, we conclude that EPA may not interpret the Act to require a PSD or Title V permit for a stationary source on sole full basis of the sources potential to emit greenhouse gases.

We begin by rejecting EPA's claim that the statue compels that interpretation.

EPA's argument is as follows:The statute requires PSD in Title V permit based on the sources potential to emit “any air pollutant.”

In Massachusetts, the Court said that greenhouse gases qualify as an air pollutant.

Therefore, the PSD inside Title V permitting requirements must apply to sources with the potential to emit greenhouse gases.

That syllogism, although superficially appealing is wrong.

In Massachusetts, the Court said that the Act's general definition of air pollutant included greenhouse gases because in the Court's view, that definition encompass literally every airborne substance.

But everyone including EPA agrees that when the Act's operative provisions impose requirements based on the sources emission of air pollutants, they do not intend such and all encompassing meaning.

Otherwise, the act would require permits for every building with the potential to emit large quantities of any substance, even one as innocuous as steam.
