ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[Il223-1b; FRL-7784-7]


Approval and Promulgation of Implementation Plans; Illinois

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to approve a site-specific revision to 
the Illinois volatile organic compound (VOC) State Implementation Plan 
(SIP) for Argonne National Laboratory's (Argonne) degreasing 
operations. Argonne is a United States government-owned research and 
development facility in Argonne, DuPage County, Illinois. By its 
submittal dated March 11, 2004, the Illinois Environmental Protection 
Agency (Illinois EPA) requested that EPA approve an Adjusted Standard, 
from Illinois' cold cleaning regulations, for Argonne's solvent 
cleaning operations because its research activities require sample 
surface areas to be completely free of any residual contamination, 
necessitating the use of cleaning solvents that exceed the vapor 
pressure limitations of Illinois' cold cleaning regulations. EPA is 
approving this adjusted standard because there are no feasible 
alternatives for the preparation of sample materials and associated 
apparatus used for research and development at Argonne's DuPage 
facility and also because no more than one ton per year of solvents are 
used for cold cleaning. In the final rules section of this Federal 
Register, EPA is approving the SIP revision as a direct final rule 
without prior proposal, because EPA 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 no adverse 
comments are received in response to this proposed rule, no further 
activity is contemplated in relation to this proposed rule. 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receives adverse comments, the direct final rule will be withdrawn and 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 on this action. Any parties interested in commenting on 
this action should do so at this time.

DATES: Written comments must be received on or before August 27, 2004.
    Comments may also be submitted electronically or through hand 
delivery/courier, please follow the detailed instructions described in 
the ADDRESS section and the SUPPLEMENTARY INFORMATION section of the 
related direct final rule which is published in the Rules section of 
this Federal Register.

ADDRESSES: Written comments should be sent to: J. Elmer Bortzer, Chief, 
Air Programs Branch (AR-18J), EPA Region 5, 77 West Jackson Boulevard, 
Chicago, Illinois 60604-3590. [email protected].

Engineer, Criteria Pollutant Section, Air Programs Branch (AR-18J), EPA
