Note: All files were reviewed using the NRC preflight profile provided on its website and have been determined to meet NRC specifications in the October 2008 revision of Guidance for Electronic Submissions to the NRC. The PDF files representing enclosure 4, 5, and 7 through 12 in this submittal include errors introduced by accessibility tagging for compliance with Section 508 of the Rehabilitation Act. As discussed with NRC staff, this tagging frequently causes the preflight to return “fonts not embedded” error messages. Specifically, the content is usually flagged as unembedded Times-Roman font. The Adobe preflight errors for unembedded fonts have been reviewed and represent non-printing and non-displaying Section 508 tagging information.
