Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, Sacramento Metropolitan

and South Coast Air Quality Management District and San Joaquin Valley

Unified Air Pollution Control 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 definitions in Sacramento Metropolitan Air Quality

Management (SMAQMD), San Joaquin Valley Unified Air Pollution Control

District (SJVUAPCD), and South Coast Air Quality Management District

(SCAQMD). The intended effect of approving this action is to

incorporate changes to the definitions for clarity and consistency and

to update the Exempt Compound list in SMAQMD, SJVUAPCD, and SCAQMD

rules to be consistent with the revised federal and state VOC

definitions.

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, SJVUAPCD, and SCAQMD 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receives adverse comments, the direct final rule will be withdrawn and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 April 19, 1999.

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.
