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
