          - [CA 240-0237b; FRL-6601-9] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

EPA is proposing to approve revisions to the Monterey Bay Unified Air Pollution Control District (MBUAPCD) portion of the California State Implementation Plan (SIP). These revisions concern amended volatile organic compound definitions and a rule rescission. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act). 

# DATES:

Any comments on this proposal must arrive by June 15, 2000. 

# ADDRESSES:

Mail comments to Andy Steckel, Rulemaking Office Chief (AIR-4), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.

# SUPPLEMENTARY INFORMATION:

                    This proposal addresses the following local rules: MBUAPCD Rules 101 and 102. 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. 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: April 18, 2000. 

Felicia Marcus, 

Regional Administrator, Region IX.
