Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, Kern County Air

Pollution Control District; Monterey Bay Unified Air Pollution Control

District; Ventura 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 revises the definition of

volatile organic compound (VOC) and updates the exempt compound list in

rules from Kern County Air Pollution Control District (KCAPCD),

Monterey Bay Unified Air Pollution Control District (MBUAPCD), and

Ventura County Air Pollution Control District (VCAPCD).

The intended effect of proposing approval of these rules is to

incorporate

[[Page 6144]]

into the SIP definition changes in the districts' rules to be

consistent with revised federal definitions. EPA is proposing approval

of these revisions 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 revisions as a

direct final rule without prior proposal because the Agency views these

changes as noncontroversial 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EPA receives adverse comments, the direct final rule will be withdrawn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

March 9, 1998.

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

Christine Vineyard, Rulemaking Office (AIR-4), Air Division, U.S.

Environmental Protection Agency, Region 9, 75 Hawthorne Street, San
