ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[CA-011-0071b; FRL-6229-6]


Approval and Promulgation of State Implementation Plans; 
California State Implementation Plan Revision, North Coast Unified Air 
Quality Management District and Northern Sonoma County Air Pollution 
Control 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 definitions in North Coast Unified Air Quality Management 
District (NCUAQMD) and Northern Sonoma County Air Pollution Control 
District (NSAPCD) Rule 130, Definitions.
    The intended effect of proposing approval of these rule is to 
incorporate changes to the definitions for clarity and consistency with 
revised federal and state definitions. EPA is proposing approval of 
these rules 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 these rules as a direct final rule 
without prior proposal because the Agency views this as 
noncontroversial 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 this 
action, 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 on this action. Any 
parties interested in commenting on this action should do so at this 
time.

DATES: Comments must be received in writing by March 11, 1999.

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