## Abstract

On January 8, 2026, the EPA published a final rule in the Federal Register approving revisions to the California State Implementation Plan (SIP). In the final rule, the EPA included inaccurate amendatory instructions that prevented full incorporation of the final rule into the Code of Federal Regulations (CFR). This correction will ensure the revisions the EPA approved for the Mojave Desert Air Quality Management District's (MDAQD) portion of the California SIP are fully reflected in the CFR.
