BILLING CODE 6560-50-P ENVIRONMENTAL PROTECTION AGENCY 40 CFR Parts 52 and 81 [IN 116-1b; FRL-6522-2] Approval and Promulgation of Implementation Plans; and Designation of Areas for Air Quality Planning Purposes; Indiana AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. SUMMARY: EPA is proposing to approve a December 21, 1999, request from Indiana for redesignation of the carbon monoxide

(CO)nonattainment areas in Lake and Marion Counties, Indiana to attainment of the CO national ambient air quality standards (NAAQS). The EPA is also proposing approval of the plans for maintaining the CO standard in the portions of these counties currently designated as not attaining the CO NAAQS. In the Final 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 revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If we receive no adverse comments in response to that direct final rule we plan to take no further activity in relation to this proposed rule. If EPA receives significant adverse comments, in writing, which have not been addressed, we will withdraw the direct final rule and address all public comments received in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on this document. DATES: Written comments must be received on or before February 18, 2000. ADDRESSES: Send written comments to: J. Elmer Bortzer, Chief, Regulation Development Section, Air Programs Branch, (AR-18J), U.S. Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.
