Air Quality: Revision to Definition of Volatile Organic 
Compounds--Exclusion of Volatile Methyl Siloxanes and 
Parachlorobenzotrifluoride

AGENCY: Envrionmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to revise EPA's definition of volatile 
organic compounds (VOC) for purposes of preparing State implementation 
plans (SIP's) to attain the national ambient air quality standards 
(NAAQS) for ozone under title I of the Clean Air Act (Act) and for the 
Federal implementation plan (FIP) for the Chicago ozone nonattainment 
area. This revision adds parachlorobenzotrifluoride (PCBTF) and 
volatile methyl siloxanes (VMS) to the list of compounds excluded from 
the definition of VOC on the basis that these compounds have negligible 
contribution to tropospheric ozone formation. In the final rules 
section of this Federal Register, the EPA is approving this definition 
revision as a final rule without prior proposal because the Agency 
views this as a noncontroversial revision amendment and anticipates no 
adverse comments. A detailed rationale for the approval is set forth in 
the final rule. If no adverse comments or requests for a public hearing 
are received in response to the final rule, no further activity is 
contemplated in relation to this proposed rule. If EPA receives adverse 
comments or requests for public hearing on the final rule, the final 
rule will be withdrawn and all public comments received will be 
addressed in a subsequent final rule based on this proposed rule. The 
30 day comment period established by this notice will be the only 
comment period instituted by EPA. Any requests for extensions of the 
comment period will be considered. The EPA will not institute a second 
comment period on this notice. Any parties interested in commenting on 
this notice should do so at this time.

DATES: Comments may be submitted until November 4, 1994. Requests for a 
public hearing must be received by November 4, 1994.

ADDRESSES: Comments on this document should be submitted in duplicate 
(if possible) to: Air and Radiation Docket and Information Center 
(6102), Attention: Docket No. A-93-47, U.S. Environmental Protection 
Agency, 401 M Street, SW, Washington, DC 20460. Comments should be 
strictly limited to the subject matter of this rule.

Public Hearing: If anyone contacts EPA requesting a public hearing, it 
will be held at Research Triangle Park, North Carolina. Persons wishing 
to request a public hearing, wanting to attend the hearing or wishing 
to present oral testimony should notify Mr. William Johnson, Air 
Quality Management Division (MD-15), U.S. Environmental Protection 
Agency, Research Triangle Park, North Carolina 27711, telephone (919) 
541-5245. The EPA will publish notice of a hearing, if a hearing is 
requested, in the Federal Register. Any hearing will be strictly 
limited to the subject matter of the rule.
