ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN99-1b; FRL-6573-6]


Approval and Promulgation of Implementation Plan; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to particulate matter 
(PM) emissions regulations for Dubois County, Indiana, which the 
Indiana Department of Environmental Management (IDEM) submitted to EPA 
on February 3, 1999, as amendments to its State Implementation Plan 
(SIP). The revisions include relaxation of some PM limits, elimination 
of limits for boilers which are no longer operating, updating facility 
names, and changing some boiler fuel types. Air quality dispersion 
modeling provided by IDEM shows that this SIP revision will not have an 
adverse effect on PM air quality.

DATES: EPA must receive written comments on this proposed rule by May 
22, 2000.

ADDRESSES: You should mail 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.
    You may inspect copies of the State submittal and EPA's analysis of 
it at: Regulation Development Section, Air Programs Branch (AR-18J), 
U.S. Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604.

FOR FURTHER INFORMATION CONTACT: David Pohlman, Environmental 
Scientist, Regulation Development Section, Air Programs Branch (AR-
