## Abstract

When EPA approved the Colorado State Implementation Plan (SIP) revision that requested redesignation of the Lamar area from nonattainment to attainment for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM<INF>10</INF>) EPA provided response to comments and in one of the response to comments, misstated our response to the comment. In this action we are making a correction to the preamble by clarifying our response to the comment raised to correct our misstatement.
