EPA Reorganizes California Air Rules Without Changing Any Requirements

## Summary

The EPA is updating how it formats certain California air quality rules to make them easier to read and find. This change affects six California air districts and won’t change any rules or costs—just the way the information is organized and shared with the public. The new format takes effect on November 6, 2026, making it simpler for everyone to access these important air plans.

## Abstract

The U.S. Environmental Protection Agency (EPA) is revising the format for materials submitted by the State of California that are incorporated by reference into the California State Implementation Plan (SIP). The regulations and other materials affected by this format change have all been previously submitted by the State of California and approved by the EPA. This format revision will primarily affect the "Identification of plan--in part" sections, as well as the format of the SIP materials that will be available for public inspection at the EPA Regional Office and the National Archives and Records Administration (NARA). This action, which only relates to rules applicable within six California air districts, is the fifth and final of a series of actions intended to change the format for the entire California SIP.
