Reopening of comment period.


On August 10, 2000, EPA published proposed regulations addressing cooling water intake structures at new facilities in the Federal Register for public review and comment (65 FR 49060). On May 25, 2001, EPA published a Notice of Data Availability in the Federal Register (66 FR 28853) regarding the proposed regulations. The comment period closed on June 25, 2001. This action reopens the comment period for certain documents for an additional 30 days, to August 6, 2001.


Comments on certain documents and issues related to those documents listed below under SUPPLEMENTARY INFORMATION will be accepted through August 6, 2001.

The Notice of Data Availability presented a summary of the data EPA had received or collected since proposal, an assessment of the relevance of the data to EPA's analysis, some modified technology options suggested by commenters, and an alternative approach suggested by a trade group representing the utility industry.

EPA received a request to extend the comment period for all documents and issues discussed in the Notice of Data Availability. After considering this request and a similar but narrower request, EPA is reopening the comment period for six documents and the issues associated with these documents because certain pages of these documents or their references and attachments were not available for public review at the time the Notice of Data Availability was published in the Federal Register. EPA is also reopening the comment period for two lengthy documents that were available in the docket in an electronic format at the start of the public comment period but were not copied and made available for off-site review until June 1, 2001. The comment period for these documents is 30 days, through August 6, 2001.

If you already submitted comments to EPA in response to the Notice of Data Availability published on May 25, 2001, and wish to submit additional comments per today's reopening, EPA requests that the later set of comments clearly specify whether they supplement or supersede the earlier-filed comments.

In addition to accepting hard-copy written comments, please note that EPA will also accept comments submitted electronically. Electronic comments must be submitted as a Word Perfect 5/Start Printed Page 355736/7/8 or ASCII file and must be submitted to:
