Utility Air Group v. Environmental Protection Agency

Questions presented

SCOTUS records, cert granted 25 Nov 2014

Emissions from electric utility steam generating units (EGUs) were extensively regulated before the Clean Air Act Amendments in 1990. Because these Amendments required substantial additional reductions in EGU emissions of conventional pollutants (e.g., sulfur dioxide and particulate matter) that would also collaterally reduce emissions of hazardous air pollutants (HAPs), Congress in 42 U.S.C. § 7412(n)(1)(A) called for regulation of only those EGU HAP emissions found to pose a hazard to public health after implementation of the other required control programs. For any remaining HAP emissions posing a residual health risk, Congress authorized only "such regulation” as was "appropriate and necessary." The court below affirmed EPA's use of this "appropriate and necessary" standard to expand EGU regulation to HAP emissions that pose no health risk and, over Judge Kavanaugh's dissent, to exclude cost from any consideration in making regu-latory decisions. The question presented is: Whether, under a statutory directive to regulate residual public health risks from EGU HAP emissions only as "appropriate and ~necessary," the Administrator (i) may regulate EGU HAP emissions that pose no hazard to public health, and (ii) may (or must as a Chevron Step One matter) ignore costs in determining "appropriate" regulation because more narrowly drawn decisional standards in the same statute require (or preclude) the Administrator from considering costs.

Opinion summary

Etalia.ai summary of the majority opinion

The Supreme Court addressed whether the Environmental Protection Agency (EPA) could regulate greenhouse gas emissions from stationary sources under the Clean Air Act. The case arose after the EPA issued a rule requiring permits for large emitters of greenhouse gases, which was challenged by industry groups and several states. The Court held that while the EPA could not require permits solely based on greenhouse gas emissions, it could regulate these emissions from sources already required to obtain permits for other pollutants. This decision partially upheld and partially invalidated the EPA's approach, affirming its authority to regulate carbon dioxide but limiting its reach in expanding permit requirements.

Dissent summary

Etalia.ai summary of the dissenting opinions

Justice Alito, joined by Justice Thomas, dissented in part. They argued that the Environmental Protection Agency (EPA) overstepped its authority under the Clean Air Act by requiring permits for greenhouse gas emissions from stationary sources like power plants and factories. The dissenters contended that Congress did not intend for these provisions to apply to such a broad range of facilities when it enacted the legislation. They expressed concern about granting too much regulatory power to an administrative agency without clear congressional authorization, warning against potential economic consequences and bureaucratic overreach. Furthermore, they criticized the majority's decision as inconsistent with statutory interpretation principles because it allowed EPA to rewrite specific thresholds set by Congress in order to make them applicable for greenhouse gases.
