Case Brief Summary & Legal Analysis
tl;dr: The EPA created a “low-risk” subcategory of polluters exempt from Clean Air Act technology standards. The D.C. Circuit invalidated the rule, holding the agency cannot use its general subcategorization power to create exemptions that circumvent the statute’s specific, technology-based regulatory scheme.
Legal Significance: This case establishes that an agency’s general authority to subcategorize sources does not permit it to create risk-based exemptions from technology-based standards when Congress has provided a separate, more stringent, and exclusive statutory process for delisting entire source categories based on risk.

Case Facts & Court Holding
Key Facts & Case Background
In the 1990 Clean Air Act (CAA) Amendments, Congress replaced a risk-based system for regulating hazardous air pollutants (HAPs) with a technology-based one. Section 112 of the CAA requires the Environmental Protection Agency (EPA) to set technology-based emission standards, known as Maximum Achievable Control Technology (MACT) standards, for every listed category and subcategory of major HAP sources. In 2004, the EPA issued a rule for the plywood and composite wood products (PCWP) industry. This rule established a “low-risk” subcategory for facilities demonstrating that their emissions did not cause a lifetime cancer risk greater than one-in-a-million to the most exposed individual. Sources qualifying for this subcategory were exempt from the MACT standards. The EPA justified this action under its general authority in § 112(c)(1) to establish subcategories “as appropriate.” However, § 112(c)(9) of the CAA provides a specific mechanism to “delist” an entire source category—not a subcategory—if it meets similar risk-based criteria. In a subsequent 2006 rule, the EPA extended the compliance deadline for the 2004 MACT standards by one year, citing “substantial” changes to testing and reporting requirements. The Natural Resources Defense Council (NRDC) challenged the legality of the low-risk subcategory and the compliance date extension.
Court Holding & Legal Precedent
Issue: Did the EPA exceed its statutory authority under the Clean Air Act by creating a low-risk subcategory of sources exempt from mandatory technology-based emission standards and by extending the compliance deadline for those standards?
Yes. The EPA’s creation of a low-risk subcategory and its extension of Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
