Approval and Promulgation of Implementation Plans; Tennessee:

Approval of Revisions to the Tennessee SIP and the Nashville/Davidson

County Portion of the Tennessee SIP Regarding Nitrogen Oxides

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to approve revisions to the Tennessee State

Implementation Plan (SIP) submitted to EPA by Tennessee, through the

Tennessee Department of Air Pollution Control (TDAPC) which add a new

chapter to the Nashville/Davidson County and the State portion of the

Tennessee SIP for the control of nitrogen oxide (NOX) emissions.

Only the portions of the Tennessee NOX rule necessary for the

approval of Tennessee's ozone redesignation request are being approved

in this notice. EPA is granting an exemption to the area under 182(f)

of the Clean Air Act (CAA) from NOX Reasonably Available Control

Technology (RACT) requirements in a separate action. The only sources

which will be subject to this rule tangentially-fired coal burning

boilers which have a heat input capacity in excess of 600 million BTU

per hour in the five county Nashville ozone nonattainment area. In the

final rules section of this Federal Register, the EPA is approving the

exemption request 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 the 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 proposed 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comments, the direct final rule will be withdrawn and all public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 document

should do so at this time.

DATES: To be considered, comments must be received by August 28, 1996.

ADDRESSES: Written comments on this action should be addressed to

William Denman at the Environmental Protection Agency, Region 4 Air

Programs Branch, 345 Courtland Street, NE, Atlanta, Georgia 30365.
