40 CFR Part 52

[CA 212-0092b; FRL-6142-6]


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 
Francisco, CA 94105-3901.
