# SUPPLEMENTARY INFORMATION:

                    This proposal addresses the following local rules: GBAPCD 101 and VCAPCD 2. In the Rules and Regulations section of this                     **Federal Register**                    , we are approving these local rules 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 an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule 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. 

Dated: October 5, 2004. 

Laura Yoshii, 

Acting Regional Administrator, Region IX.
