[CA105-0037b; FRL-5842-7]

Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, San Diego County Air

Pollution Control District, Yolo-Solano 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) which concern the control of oxides of

nitrogen (NOX) from stationary gas turbine engines,

industrial, institutional, and commercial boilers, steam generators,

and process heaters.

The intended effect of proposing approval of these rules is to

regulate emissions of NOX in accordance with the

requirements 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 SIP

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 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adverse comments, the direct final rule will be withdrawn and all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

July 17, 1997.

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

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

Protection Agency, Region 9, 75 Hawthorne Street, San Francisco, CA
