40 CFR Part 52

[CA 210-0103b; FRL-6185-2]

Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, Sacramento Metropolitan

Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is approving revisions to the California State

Implementation Plan (SIP). This action is an administrative change

which revises the definition of volatile organic compound (VOC) and

updates the Exempt Compound list in rules from the Sacramento

Metropolitan Air Quality Management District (SMAQMD).

The intended effect of proposing approval of this action is to

incorporate changes to the definition of VOC and to update the Exempt

Compound list in SMAQMD rules to be consistent with the revised federal

and state VOC definitions. EPA is proposing approval of these revisions

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 (CAA or the Act). In the Final Rules Section of

this Federal Register, the EPA is approving the state's SIP submittal

as a direct final rule without prior proposal because the Agency views

this 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, no further

activity is contemplated. 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final rule will be withdrawn and all public comments received will be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. Any parties interested

in commenting should do so at this time.

DATES: Written comments must be received by December 9, 1998.

ADDRESSES: Comments should be addressed to: Andrew Steckel, Chief,

Rulemaking Office (AIR-4), Air Division, U.S. Environmental Protection

Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.

rule are available for public inspection at EPA's Region 9 office
