40 CFR Part 52

[CA-071-0069b; FRL-6129-6]


Approval and Promulgation of State Implementation Plans; 
California State Implementation Plan Revision, Mendocino County 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 revises two definitions and adds one definition in Mendocino 
County Air Quality Management District (MCAQMD) Rule 130, Definitions.
    The intended effect of proposing approval of this rule 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 and maintenance of the national ambient air quality 
standards (NAAQS) 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 as a 
noncontroversial revision amendment 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 proposed 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. Any 
parties interested in commenting should do so at this time.

DATES: Comments must be received in writing by August 31, 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 9, 75 Hawthorne Street, San
