Ninth Circuit Court of Appeals: No Feasibility Exemptions for San Joaquin Valley Air Quality Plan

• A Ninth Circuit panel remanded the EPA's air quality plan for the San Joaquin Valley due to a feasibility exemption inserted into Section 172(c)(9) of the Clean Air Act.
• The decision sets a precedent for strict statutory interpretation, limiting the agency's ability to consider feasibility exemptions in similar cases.
• The ruling may lead to more stringent regulations and greater accountability from states to meet air quality standards.

The purpose of the act is to require states to properly regulate air pollution.

A three-judge panel of the Ninth Circuit Court of Appeals has remanded a contentious air quality plan proposed by the Environmental Protection Agency (EPA) for the San Joaquin Valley, one of the most polluted regions in the country. The decision, which sets a precedent for strict statutory interpretation, may limit the agency's ability to consider feasibility exemptions in similar cases. At issue is Section 172(c)(9) of the Clean Air Act, which requires states to implement contingency measures to meet air quality standards. However, the EPA had inserted a feasibility exemption into this section, arguing that it was permissible due to other provisions in the act allowing for such considerations.

The Clean Air Act is a federal law that sets national standards for air quality. Under this law, states are responsible for implementing plans to meet these standards, but the EPA plays a crucial role in reviewing and approving these plans. In the case of the San Joaquin Valley, the EPA had proposed a rule that would have allowed for feasibility analyses to justify emissions reductions not meeting the necessary standard. However, environmental groups argued that this approach was inconsistent with the Clean Air Act's requirement that contingency measures provide for 'one year's worth of reasonable further progress.' The Ninth Circuit's decision is significant because it establishes that the EPA cannot insert feasibility exemptions into sections of the act where they are not explicitly allowed.

The Ninth Circuit's ruling has important implications for future EPA rulemaking. By setting a precedent for strict statutory interpretation, the decision may limit the agency's ability to consider feasibility exemptions in similar cases. This could lead to more stringent regulations and greater accountability from states to meet air quality standards. As the court noted, 'the purpose of the act is to require states to properly regulate air pollution.' The decision also highlights the importance of clear and consistent application of federal laws, particularly in areas where public health and environmental protection are at stake.

Lawyers and compliance officers should watch for the potential impact on future EPA rulemaking, as this decision sets a precedent for strict statutory interpretation and may limit the agency's ability to consider feasibility exemptions in similar cases.
