AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve revisions to the California State

Implementation Plan (SIP) which control oxides of nitrogen (NOX)

from boilers and process heaters, internal combustion engines,

residential water heaters, and gas turbines. 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 Rules section of this Federal Register,

EPA is approving the State's SIP revision as a direct final rule

without prior proposal because the Agency views this as a

noncontroversial action 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 action,

no further activity is contemplated in relation to this action. 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receives adverse comments, the direct final rule will be withdrawn and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

December 2, 1996.
