[CA 164-0112b; FRL-6227-3]

Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, San Joaquin Valley

Unified Air Pollution Control District, Sacramento Metropolitan 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) emissions from solid fuel fired boilers,

steam generators and process heaters within the San Joaquin Valley

Unified Air Pollution Control District and from stationary gas turbine

operations within the Sacramento Metropolitan Air Quality Management

District.

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 revision

amendment 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 rule, no further activity is

contemplated in relation to this rule. If EPA receives 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 document. Any parties interested in commenting on this action

should do so at this time.

DATES: Written comments must be received by March 15, 1999.

ADDRESSES: Written comments should be addressed to: Andrew Steckel,

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 IX office
