Throughout this document, “we,” “us” and “our” refer to the EPA. This proposal addresses base year EIs for the Calaveras County, Chico (Butte County), San Francisco Bay Area and San Luis Obispo (Eastern San Luis Obispo) 2008 ozone NAAQS nonattainment areas. We are approving these base year EIs in a direct final action without prior proposal because we believe these SIP revisions are not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule. Please note that if we receive adverse comment on a particular base year EI, we may adopt as final those that are not the subject of an adverse comment.

We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action.
