Approval and Promulgation of State Implementation Plans;

California State Implementation Plan Revision; Ventura County Air

Pollution Control District; Sacramento Metropolitan Air Quality

Management Division; Placer County Air Pollution Control 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 natural gas-fired central furnaces,

stationary internal combustion engines, and biomass boilers.

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 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final rule will be withdrawn and all public comments received will be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

May 30, 1996.
