ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2006-0002; FRL-8166-8]


Approval and Promulgation of Air Quality Implementation Plans; 
Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to approve revisions to the Indiana 
particulate matter (PM10) State Implementation Plan (SIP). 
On December 15, 2005, Indiana requested revisions for sources at the 
ASF Keystone, Inc. (Keystone) coil spring manufacturing facility in 
Lake County, Indiana. The requested revisions will increase the 
PM10 emission limit for one unit and reduce the limits for 
two units. The changes result in a net decrease in the allowable 
emissions. The emission limits for a fourth unit that has shut down are 
also being removed. Indiana also requested removing the process weight 
rate limits and using pounds of PM10 per hour (lb/hr) as the 
short-term emission limit. The maximum permissible PM10 
emissions will not increase after removing the process weight rate 
limits because of the net decrease in short-term emission limits.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the State's SIP submittal 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 rule, 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direct final rule will be withdrawn and all public comments received 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. EPA will not institute a second comment period. Any parties 
interested in commenting on this action should do so at this time. 
Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment. For 
additional information, see the direct final rule which is located in 
the Rules section of this Federal Register.

    Dated: April 20, 2006.

Acting Regional Administrator, Region 5.
