DATES:

Comments. The comment period has been extended from May 29, 2007. Comments must now be received on or before June 29, 2007.

ADDRESSES:

  • www.regulations.gov. Follow the on-line instructions for submitting comments.
  • E-mail: a-and-r-docket@epa.gov, Attention Docket ID No. EPA-HQ-OAR-2006-0859.
  • Facsimile: (202) 566-1741, Attention Docket ID No. EPA-HQ-OAR-2006-0859.

  • Hand Delivery: In person or by courier, deliver comments to: EPA Docket Center (6102T), EPA West, Room 3334, 1301 Constitution Avenue, NW., 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. Please include a total of two copies.

Instructions: Direct your comments to Docket ID No. EPA-HQ-OAR-2006-0859. As described further in section VII of the advanced notice of proposed rulemaking, specific data change suggestions need to be accompanied by supporting documentation that includes a description of any assumptions used and any technical information and/or data that you used. We strongly urge that all data revision comments be submitted in the form of updated Microsoft(r) Access files, which are provided on the http://www.epa.gov/​ttn/​atw/​rrisk/​rtrpg.html webpage. Data in the form of written descriptions or other electronic file formats will be difficult for EPA to translate into the necessary format in a timely manner. Additionally, placing the burden on EPA to interpret data submitted in other formats increases the possibility of misinterpretation or errors. 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. Send or deliver information identified as CBI only to the following address: Mr. Roberto Morales, OAQPS Document Control Officer, U.S. EPA (C404-02), Attention Docket ID No. EPA-HQ-OAR-2006-0859, Research Triangle Park, NC 27711. Clearly mark the part or all of the information that you claim to be CBI. 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.

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, (i.e., 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 EPA Docket Center, EPA West, Room 3334, 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 EPA Docket Center is (202) 566-1742.

SUPPLEMENTARY INFORMATION:

Regulated Entities. Entities potentially affected by this action include facilities containing any one or more of the 22 major source categories subject to the 12 national emission standards for hazardous air pollutants (NESHAP) (or commonly referred to maximum achievable control technology (MACT) standards) listed in Table 1. The Petroleum Refineries source category is affected by this action, but will not receive an extension of the comment period due to the court-ordered deadline of August 22, 2007, for proposal of the technology review. This action does not affect area sources, as these NESHAP do not apply to area sources. Industries regulated by these MACT are classified by the North American Industry Classification System (NAICS) codes shown in Table 1. In addition, a classification system of MACT codes has been developed and is used in the 2002 National Emissions Inventory to identify processes included in each MACT source category. The MACT codes for the 22 source categories addressed in this notice are also displayed in Table 1.
