[CA 207-0106b; FRL-6210-9]

Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision, Mojave Desert 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 the operations of fuel burning

equipment, electric power generating equipment, and steam generating

equipment within the Mojave Desert Air Quality Management District

(MDAQMD).

The intended effect of proposing approval of these revisions 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, 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 rule. Any parties interested

in commenting on this rule should do so at this time.

DATES: Written comments must be received by February 10, 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
