## Abstract

The Environmental Protection Agency (EPA) published in the January 25, 2016 Federal Register a document concerning the approval of Air Quality State Implementation Plan (SIP) revisions to Colorado Common Provisions and Regulation Number 3. Inadvertently, the publication date of January 25, 2016 was listed in the regulatory text under the heading "EPA Effective Date" instead of the effective date of February 24, 2016. The correct EPA effective date was provided in the rule preamble. This document corrects the "EPA Effective Date" within the regulatory text to February 24, 2016.
