April 27, 2012

To SEG Interested Parties:

The participants at the Interim SEG meeting held on April 3 recommended that the next full SEG meeting take place on May 22.

that time, the U. S. Army Corps of Engineers released the Final GRR and EIS for state, agency and public review and comment. The comment period on those documents ends at Noon on May 21, 2012. It is important that all interested parties take the opportunity to participate in this comment period, and we encourage you to do so. Comments should be mailed to:

US Army Corps of Engineers
7701 Telegraph Road
Alexandria, VA 22315-3860

As participants in the SEG process over the past thirteen plus years and more than 70 meetings, not to mention numerous committee meetings, each individual and organization involved has contributed to the improvement of the Savannah Harbor Expansion Project (SHEP). Your time, talents, insights, and interest through the years are appreciated. You will recognize that the final Corps documents include the SEG summary report and incorporate useful clarifications and significant project improvements that are directly responsive to comments that several of you submitted on the draft reports.
We have been advised by our attorneys that we should not host another SEG meeting.  The organizations of several SEG participants have either filed or are representing multiple challenges in court, and have listed other SEG participants as witnesses.  Therefore, we are unable to hold further SEG discussions.

Thank you again for your contributions.  We certainly appreciate all of the time and effort that you contributed towards the study process for the Savannah Harbor Expansion Project.

Status of Analysis or Study Tasks
For a description of the scope of work, please refer to the Project Management Plan, Appendix H. Note that while the status may be listed as complete, any analysis may have to be reevaluated and revised if the parameters on which it was based are revised by modifications to the project alternatives. Such modifications could be caused by changes to USACE policy or procedures, modification of mitigation plan features, modification of the basic alternatives, or other factors. If such modifications occur, new analysis reports, if produced will be posted as soon as they are available. However, revised reports may not be produced. In this case, the results of the analyses will be included in the General Reevaluation Study Report or its Appendices (Engineering, Economic, and Real Estate) as well as in the Tier II EIS where appropriate.
