## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Eastern Kern Air Pollution Control District (EKAPCD) and Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). These revisions were submitted by the California Air Resources Board (CARB) in response to EPA's June 12, 2015, finding of substantial inadequacy and SIP call for certain provisions in the SIP related to affirmative defenses applicable to excess emissions during startup, shutdown, and malfunction (SSM) events. EPA is finalizing approval of the SIP revisions because the Agency has determined that they are in accordance with the requirements for SIP provisions under the Clean Air Act (CAA or the Act) and correct deficiencies identified in the June 12, 2015 SIP call.
