Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, South Coast Air Quality

Management 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 stationary sources, including process

industries and cement plants, within the South Coast Air Quality

Management District (SCAQMD).

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

in response to this rule, 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 rule. Any

parties interested in commenting should do so at this time.

DATES: Comments must be received in writing by October 2, 1998.

ADDRESSES: Written comments on this action should be addressed to:

Andrew Steckel, Rulemaking Office (AIR-4), Air Division, U.S.

Environmental Protection Agency, Region IX, 75 Hawthorne Street, San
