# SUPPLEMENTARY INFORMATION:

## I. Why Is EPA Issuing This Proposed Rule? 

                    This document proposes to take action on SIP revisions pertaining to the El Paso area. We have published a direct final rule approving the State's SIP revisions in the “Rules and Regulations” section of this                     **Federal Register**                     because we view this as a noncontroversial action and anticipate no adverse comment. We have explained our reasons for this action in the preamble to the direct final rule.                 

If we receive no adverse comment, we will not take further action on this proposed rule. If we receive adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based upon this proposed rule. 

                    We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please see the information provided in the                     **ADDRESSES**                     section of this document.
