Reportable Quantity Adjustment for Isophorone Diisocyanate

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
adjust the reportable quantity (RQ) for Isophorone Diisocyanate (IPDI). 
Reportable quantities for many of the Extremely Hazardous Substances 
(EHSs) under the Emergency Planning and Community Right-to-Know Act 
(EPCRA) were adjusted to their threshold planning quantities (TPQ) in a 
final rule on May 7, 1996. On September 8, 2003, EPA modified the TPQ 
for IPDI to 500 pounds. However, EPA inadvertantly omitted an RQ 
adjustment for this substance. Therefore, EPA is now proposing to 
adjust the RQ for IPDI to be 500 pounds.
    In the ``Rules and Regulations'' section of the Federal Register, 
we are revising the RQ for Isophorone Diisocyanate to 500 pounds 
without prior proposal because we view the revision as noncontroversial 
and anticipate no adverse comment. We have explained our reasons for 
this approach in the preamble to the direct final rule.
    If we receive adverse comment on this revision, however, we will 
withdraw this direct final action and it will not take effect. We will 
address all public comments in a subsequent final rule based on this 
proposed rule. We will not institute a second comment period on this 
action. Any parties interested in commenting on any amendment must do 
so at this time.

DATES: Comments must be received on or before October 11, 2006.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-HQ-
SFUND-2005-0520, by one of the following methods:
    1. www.regulations.gov: Follow the on-line instructions for 
submitting comments.
    2. E-mail: [email protected].
    3. Fax: (202) 566-0224.
    4. Mail: Superfund Docket, Environmental Protection Agency, 
Mailcode: 5305T, 1200 Pennsylvania Ave., NW., Washington, DC 20460.
    5. Hand Delivery: Superfund Docket, EPA Docket Center, 1301 
Constitution Avenue, NW., EPA West Building, Room B-102, Washington DC 
20004. Such deliveries are only accepted during the Docket's normal 
hours of operation, and special arrangements should be made for 
deliveries of boxed information.
    Instructions: Direct your comments to Docket ID No. EPA-HQ-SFUND-
2005-0520. EPA's policy is that all comments received will be included 
in the public docket without change and may be made available online at 
www.regulations.gov, including any personal information provided, 
unless the comment includes information claimed to be Confidential 
Business Information (CBI) or other information whose disclosure is 
restricted by statute. Do not submit information that you consider to 
be CBI or otherwise protected through www.regulations.gov or e-mail. 
The www.regulations.gov Web site is an ``anonymous access'' system, 
which means EPA will not know your identity or contact information 
unless you provide it in the body of your comment. If you send an e-
mail comment directly to EPA without going through www.regulations.gov, 
your e-mail address will be automatically captured and included as part 
of the comment that is placed in the public docket and made available 
on the Internet. If you submit an electronic comment, EPA recommends 
that you include your name and other contact information in the body of 
your comment and with any disk or CD-ROM you submit. If EPA cannot read 
your comment due to technical difficulties and cannot contact you for 
clarification, EPA may not be able to consider your comment. Electronic 
files should avoid the use of special characters, any form of 
encryption, and be free of any defects or viruses. For additional 
information about EPA's public docket, visit the EPA Docket Center 
homepage at http://www.epa.gov/epahome/dockets.htm.
    Docket: All documents in the docket are listed in the 
www.regulations.gov index. Although listed in the index, some 
information is not publicly available, e.g., CBI or other information 
whose disclosure is restricted by statute. Certain other material, such 
as copyrighted material, will be publicly available only in hard copy. 
Publicly available docket materials are available either electronically 
in www.regulations.gov or in hard copy at the Superfund Docket, EPA/DC, 
EPA West, Room B102, 1301 Constitution Ave., NW., Washington, DC. The 
Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through 
Friday, excluding legal holidays. The telephone number for the Public 
Reading Room is (202) 566-1744, and the telephone number for the 
Superfund Docket is (202) 566-0276). This Docket Facility is open from 
8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays.


    Note: The EPA Docket Center suffered damage due to flooding 
during the last week of June 2006. The Docket Center is continuing 
to operate. However, during the cleanup, there will be temporary 
changes to Docket Center telephone numbers, addresses, and hours of 
operation for people who wish to make hand deliveries or visit the 
Public Reading Room to view documents. Consult EPA's Federal 
Register notice at 71 FR 38147 (July 5, 2006) or the EPA Web site at 
http://www.epa.gov/epahome/dockets.htm for current information on 
docket operations, locations and telephone numbers. The Docket 
Center's mailing address for U.S. mail and the procedure for 
submitting comments to www.regulations.gov are not affected by the 
flooding and will remain the same.
