# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

EPA is proposing to approve a revision to the Monterey Bay Unified Air Pollution Control District (MBUAPCD) portion of the California State Implementation Plan (SIP). This revision concerns the control of emissions of Oxides of Nitrogen (Nox) and sulfur compounds. We are proposing to approve a local rule to regulate these emissions under the Clean Air Act as amended in 1990 (CAA or the Act). 

# DATE:

Any comments on this proposal must arrive by July 12, 2001.

# SUPPLEMENTARY INFORMATION:

                    This proposal addresses the following local rule: MBUAPCD 404, Sulfur Compounds and Nitrogen Oxides. In the Rules and Regulations section of this                     **Federal Register**                    , we are approving this local rule in a direct final action without prior proposal because we believe this SIP revision is 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. 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: May 8, 2001.

Acting Regional Administrator, Region IX.
