Dear Mr. Gottlieb:
On April 24, 2008, the Division of Water Quality (DWQ) received your application dated April 8, 2008,

Zone 2 Neuse River basin protected riparian buffers to construct the proposed museum expansion project
at the site. The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to process your
application to impact protected wetlands and/or streams on the subject property. Therefore, unless we
