## Abstract

On July 10, 2019, the Environmental Protection Agency (EPA) published in the Federal Register a rule entitled "Designation of Areas for Air Quality Planning Purposes; California; Coachella Valley 8-Hour Ozone Nonattainment Area; Reclassification to Extreme." That publication inadvertently included the incorrect docket number for the rule. This document corrects that error.
