a reissuance of EPA=s NPDES Stormwater Multi-Sector General Permit (MSGP). This general
permit, MSGP 2006, when finalized, will replace the MSGP 2000, which was issued on October
30, 2000 (65 FR 64746), and expired on October 30, 2005.
Public Comment
EPA is soliciting comment on the proposed MSGP 2006. Comments on any provision of
the permit, or comments on the fact sheet discussion are welcome. The comment period is open
for 45 days from publication of this Notice in the Federal Register. Comments may be submitted
to EPA in the following ways:

EPA Dockets. Your use of EPA's electronic public docket to submit comments to
EPA electronically is EPA's preferred method for receiving comments. Go directly to
EPA Dockets at
H
http://www.epa.gov/edocket,
and follow the online instructions for
submitting comments. Once in the system, select search, and then key in Docket ID
No. OW-2005-0007. The system is an anonymous access system, which means
EPA will not know your identity, e-mail address, or other contact information unless
you provide it in the body of your comment.

E-mail. Comments may be sent by electronic mail (e-mail) to ow-docket@epa.gov,
Attention Docket ID No. OW-2005-0007. In contrast to EPA's electronic public
docket, EPA's e-mail system is not an anonymous access system. If you send an e-
mail comment directly to the Docket without going through EPA's electronic public
docket, EPA's e-mail system automatically captures your e-mail address. E-mail
addresses that are automatically captured by EPA's e-mail system are included as part
of the comment that is placed in the official public docket, and made available in
EPA's electronic public docket.

Disk or CD-ROM. You may submit comments on a disk or CD-ROM that you mail to
the mailing address identified in Section I.B.2. These electronic submissions will be
accepted in Microsoft Word or ASCII file format. Avoid the use of special characters
and any form of encryption.

By Mail. Send the original and three copies of your comments to: Water Docket,
Environmental Protection Agency, Mailcode: 4101T, 1200 Pennsylvania Ave., NW.,
Washington, DC, 20460, Attention Docket ID No. OW-2005-0007.
