40 CFR Part 52

[CA-169-0065b; FRL-5979-6]


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). This action is an administrative change 
which revised various definitions in South Coast Air Quality Management 
District (SCAQMD) Rule 102, Definition of Terms.
    The intended effect of proposing approval of this action is to 
incorporate changes to the definitions for clarity and consistency with 
revised Federal and state definitions. EPA is proposing approval of 
this revision to be incorporated into the California SIP for the 
attainment of the National ambient air quality standards (NAAQS) for 
ozone under title I 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 administrative change 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 adverse comments are received in response to this proposed 
rule, no further activity is contemplated in relation to this rule. If 
EPA receives adverse comments, the direct final rule will be withdrawn 
and all public comments received will be addressed in a subsequent 
final rule based on this proposed rule. The EPA will not institute a 
second comment period on this document. Any parties interested in 
commenting on this action should do so at this time.

DATES: Comments on this proposed rule must be received in writing by 
April 20, 1998.

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