ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[CA 022-0087b; FRL-6138-3]


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 a revision to the California State 
Implementation Plan (SIP) which concerns the control of oxides of 
nitrogen (NOX) from electric power generating systems within 
the South Coast Air Quality Management District. The intended effect of 
proposing approval of this rule is to regulate emissions of 
NOX in accordance with the requirements of the Clean Air 
Act, as amended in 1990 (CAA or the Act). In the Rules section of this 
Federal Register, EPA is approving the State's SIP revision as a direct 
final rule without prior proposal because the Agency views this as a 
noncontroversial action 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 the direct 
final 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 action. Any parties 
interested in commenting on should do so at this time.

DATES: Comments must be received in writing by September 10, 1998.

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.
