Narrative Opinion Summary
This case involves consolidated petitions for review of the EPA's 2004 and 2006 final rules regulating hazardous air pollutants (HAPs) from plywood and composite wood products (PCWP) under the Clean Air Act (CAA). The Natural Resources Defense Council (NRDC), Sierra Club, and Environmental Integrity Project argue that the EPA failed to meet statutory requirements by not setting emission standards, creating unauthorized risk-based subcategories, and extending compliance deadlines. The court vacated and remanded the 2004 Rule for failure to set necessary emission standards and found that the EPA overstepped its authority by establishing a low-risk subcategory and extending deadlines, siding with the NRDC's petitions on these grounds. Conversely, Louisiana-Pacific Corporation's petition, claiming arbitrary actions by the EPA in not creating a subcategory for wet/wet hardboard presses, was denied. The court applied the Chevron standard to assess the EPA's interpretation of the CAA, determining that the EPA must explore alternatives to regulate emissions more effectively. The court also addressed the NRDC's standing under Article III, affirming that the NRDC members demonstrated injury-in-fact. The vacatur of the challenged provisions was deemed necessary, with the EPA given no affirmative relief requested by industry intervenors. This case underscores the statutory obligations and limitations of the EPA's regulatory authority under the CAA.

Application: The court applied the Chevron standard to assess the EPA's interpretation of the Clean Air Act, finding the EPA's approach insufficient.
Reasoning: In reviewing the EPA's application of the Clean Air Act, the court applies the Chevron standard.
Compliance Deadline Extensionssubscribe to see similar legal issues
Application: The court ruled that the EPA exceeded its authority by extending the compliance deadlines stipulated under the Clean Air Act.
Reasoning: In the 2006 Rule, EPA extended the compliance date for emissions standards established in the 2004 Rule by one year, citing significant changes.
Establishment of Risk-Based Subcategoriessubscribe to see similar legal issues
Application: The court found that the EPA lacked authority to create a low-risk subcategory for hazardous air pollutant sources.
Reasoning: It also finds that the EPA lacked authority to create a low-risk subcategory and to extend compliance deadlines, granting NRDC’s petitions on these issues.
Maximum Achievable Control Technology (MACT) Standardssubscribe to see similar legal issues
Application: The EPA's MACT standards must reflect the maximum reduction achievable, but the court found the EPA's rationale for not setting standards insufficient.
Reasoning: The EPA's rationale for not setting standards—based on the lack of control technology—was deemed insufficient, as it must explore alternative means to regulate emissions.
Regulatory Authority under the Clean Air Actsubscribe to see similar legal issues
Application: The court vacated and remanded the EPA's 2004 Rule for not setting emission standards for HAPs as required by the Clean Air Act.
Reasoning: The court vacates and remands the 2004 Rule for not setting emission standards for HAPs, agreeing with NRDC’s position while allowing EPA to consider additional remedies.
Standing under Article IIIsubscribe to see similar legal issues
Application: NRDC's standing to challenge the EPA rules was upheld based on affidavits demonstrating actual injury to its members.
Reasoning: Consequently, the NRDC members satisfy the Lujan standing test, allowing their challenge against the 2004 and 2006 rules to proceed despite industry objections.
Statutory Interpretation of Categories and Subcategoriessubscribe to see similar legal issues
Application: The court found the EPA's interpretation of categories and subcategories under the Clean Air Act to be flawed, leading to vacatur of the rules.
Reasoning: Congress used the terms 'category' and 'subcategory' interchangeably but did not clarify their meanings in subsection 112(c)(9)(B), leading to a debate on statutory interpretation.
Variance Procedure under the Clean Air Actsubscribe to see similar legal issues
Application: L-P's request for a variance was denied as the Clean Air Act does not mandate the EPA to grant variances for individual plant circumstances.
Reasoning: The Environmental Protection Agency (EPA) is not mandated to grant a variance under the Clean Air Act, and the cases cited by L-P from the Clean Water Act are not relevant.
