The Federal Clean Air Act (CAA) requires each state to adopt and submit to the U.S. EPA, a plan that provides for implementation, maintenance, and enforcement of the National Ambient Air Quality Standards (NAAQS). This plan, generally referred to as an Infrastructure SIP, describes the infrastructure (authorities, resources, and programs) California has in place to implement, maintain, and enforce the NAAQS. The Infrastructure SIP revision is administrative in nature and does not contain any proposals for emission control measures.

• 2024 California Transport SIP Amendment
  • The California Air Resources Board 2024 Transport State Implementation Plan (SIP), which details California's plan to address the interstate transport portion of the Infrastructure SIP by replacing the previously disapproved Transport SIP with an updated SIP fully addressing the requirements of the Clean Air Act Section 110(a)(2)(D)(i)(I) is now available for public review.
