Dear Mr. Miller:
The Wilmington Regional Office received a complete'Stormwater Management Permit Application for Superior
Center on June 30, 1999. Staff review of the plans and specifications has determined that the project, as proposed,
will comply with the Stormwater Regulations set forth in Title I5A NCAC 2H.1000. We are forwarding Permit
No. SW8 990236 dated August 11, 1999, for the construction of Superior Center.
This permit shall be effective from the date of issuance until August 11, 2009, and shall be subject to the conditions -
and Iimitations as specified therein. Please pay special attention to the Operation and Maintenance requirements
in this permit. Failure to establisli an adequate system foroperation and maintenance of the stormwater management
system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
ad j udicatory hearing upon written request within thirty (3 0) days following receipt of this permit. This request must
be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
