ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IL140-1-7283b; IL141-1-7284b; FRL- 5441-6]


Approval and Promulgation of Implementation Plans; Illinois

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The United States Environmental Protection Agency (USEPA) 
proposes to approve Illinois' November 14, 1995 request to incorporate 
an exemption for acetone from the definitions of Organic Material and 
Organic Materials, Petroleum Liquid, and Volatile Organic Matter (VOM) 
or Volatile Organic Compounds (VOC) contained in the Illinois State 
Implementation Plan (SIP) and thereby from regulation as an ozone 
precursor. The USEPA also proposes to approve Illinois' November 15, 
1995 request to revise the definition of VOM or VOC contained in the 
Illinois SIP to incorporate an exemption for parachlorobenzotrifluoride 
and cyclic, branched or linear completely-methylated siloxanes from the 
definition of VOM or VOC and thereby, from regulation as ozone 
precursors. These requested SIP revisions were made in response to and 
consistent with USEPA's action to add these chemical compounds to the 
list of chemicals that are exempted from the definition of VOC. In the 
final rules section of this Federal Register, the USEPA is approving 
these actions as a direct final rule without prior proposal because 
USEPA views this as a noncontroversial action 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 that direct final rule, no further activity is contemplated in 
relation to this proposed rule. If USEPA 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direct final rule will be withdrawn and all public comments received 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 the proposed 
rule. USEPA will not institute a second comment period on this action. 
Any parties interested in commenting on this document should do so at 
this time.

DATES: Comments on this proposed rule must be received on or before 
April 22, 1996.

ADDRESSES: Written comments should be mailed to: J. Elmer Bortzer, 
Chief, Regulation Development Section, Air Programs Branch (AR18-J), 
U.S. Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604.
    Copies of the State submittal and USEPA's analysis of it are 
available for inspection at: Regulation Development Section, Air 
Programs Branch (AR18-J), U.S. Environmental Protection Agency, Region 
5, 77 West Jackson Boulevard, Chicago, Illinois 60604.

FOR FURTHER INFORMATION CONTACT: Randolph O. Cano, Regulation 
Development Section, Air Programs Branch (AR-18J), U.S. Environmental 
Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago,
