## Abstract

On October 6, 2016, the Environmental Protection Agency (EPA) published a final rule in the Federal Register approving certain revisions to the Northern Sonoma County Air Pollution Control District (NSCAPCD, or the District) portion of the California State Implementation Plan (SIP), and disapproving others. The EPA indicated in this final action that these revisions would supersede certain older rules in the California SIP but inadvertently included erroneous references in the regulatory text. This document corrects the regulatory text to clarify the replacement of these superseded regulations.
