[CA 211-0105; FRL-6195-9]

Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, San Diego Air Pollution

Control District and Ventura County Air Pollution Control District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve revisions to the California State

Implementation Plan (SIP) which concern the control of particulate

matter (PM) emissions from visible emissions and abrasive blasting.

The intended effect of proposing approval of these rules is to

regulate emissions of PM in accordance with the requirements of the

Clean Air Act, as amended in 1990 (CAA or the Act). In the Final Rules

section of this Federal Register, the EPA is approving the state's SIP

revision as a direct final rule without prior proposal because the

Agency views this as a noncontroversial revision and anticipates no

adverse comments. A detailed rationale for this approval is set forth

in the direct final rule. If no relevant adverse comments are received,

no further activity is contemplated in relation to this rule. If EPA

receives relevant adverse comments, the direct final rule will not take

effect and all public comments received will be addressed in a

subsequent final rule based on this proposed rule. EPA will not

institute a second comment period on this action. Any parties

interested in commenting on this action should do so at this time.

DATES: Comments must be received January 6, 1999.

ADDRESSES: Written comments should be addressed to: Andrew Steckel,

Rulemaking Office (AIR-4), Air Division, U.S. Environmental Protection

Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.
