Approval and Promulgation of Implementation Plans, Tennessee:

Approval of Revisions to the Knox County Portion of the Tennessee SIP

Regarding Use of LAER for Major Modifications and Revisions to the

Tennessee SIP Regarding the Coating of Miscellaneous Metal Parts

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to take action on revisions to Sections 46.2

and 46.3.A. of the Knox County portion of the Tennessee State

Implementation Plan (SIP) which were submitted by the Tennessee

Department of Air Pollution Control (TDAPC), on May 23, 1995, and

November 13, 1998, for purposes of revising the definition for Volatile

Organic Compounds (VOC) and requiring the use of Lowest Achievable

Emission Rate (LAER) for major modifications to existing sources of

VOC. The EPA also proposes to approve revisions to the Tennessee SIP

which were submitted by TDAPC on February 12, 1999, and May 17, 1999,

for purposes of revising Rule 1200-3-18-.20 (Coating of Miscellaneous

Metal Parts) to include a standard for the touch-up of heavy-duty

trucks and revise the definition of ``high performance architectural

coating.'' 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

submittal 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 action, no further activity

is contemplated. 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rule will be withdrawn and all public comments received will be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: Written comments must be received on or before December 3, 1999.

ADDRESSES: All comments should be addressed to: Allison Humphris at the

EPA, Region 4 Air Planning Branch, 61 Forsyth Street, SW, Atlanta,

Georgia 30303.
