Dear Mr. Willis:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Willis Storage on March 9, 2005. Staff review of the plans and specifications
has determined that the project, as proposed, will comply with the Stormwater Regulations set

future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within thirty (30) days
following receipt of this permit. This request must be in the form of a written petition,
