40 CFR Part 52

[OK-3-1-5201b; FRL-6470-5]

Approval and Promulgation of Implementation Plans; Oklahoma;

Visibility Protection

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to take direct final action approving a

revision to the Oklahoma State Implementation Plan (SIP). The revision

concerns approval of the Oklahoma Visibility Protection Plan for the

Federal Class I area. The EPA is also proposing to remove the

disapproval of the Oklahoma SIP and resultant Federal Implementation

Plan for failure to meet the requirements of section 169A of the

Federal Clean Air Act.

In the ``Rules and Regulations'' section of this Federal Register,

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

without prior proposal because EPA views this as a noncontroversial

revision and anticipates no adverse comment. The EPA has explained its

reasons for this approval in the preamble to the direct final rule. If

EPA receives no relevant adverse comment, EPA will not take further

action on this proposed rule. If EPA receives relevant adverse comment,

EPA will withdraw the direct final rule and it will not take effect.

The EPA will address all public comments in a subsequent final rule

based on this proposed rule. The EPA will not institute a second

comment period on this action. Any parties interested in commenting

must do so at this time.

DATES: Written comments must be received by December 8, 1999.

ADDRESSES: Written comments should be addressed to Mr. Thomas H. Diggs,

Chief, Air Planning Section (6PD-L), at the EPA Region 6 Office listed

below. Copies of documents relevant to this action are available for

public inspection during normal business hours at the following
