Dear Mr. Daily:
The Wilmington Regional Office received a complete Stormwater Management Permit Renewal
Application for Wal-Mart Super Center #1392-00 on May 10, 2012. The Division is hereby
notifying you that permit SW8 990423 has been renewed on June 25, 2012, and shall be
effective until September 28, 2021. The renewal and reissuance of this stormwater permit does
not imply that the site is currently in compliance with the terms and conditions of this state
stormwater permit. The plans previously approved on September 28, 1999, in accordance with
the regulations set forth in Title 15A NCAC 2H.1000 effective September 1, 1995, remain in full
force and effect. Please attach this cover letter and permit addendum to your High Density
Permit originally issued on September 28, 1999.
This permit is subject to the conditions and limitations as specified therein. Please pay special
attention to the conditions listed in this permit regarding the Operation and Maintenance of the
BMP(s), recordation of deed restrictions, procedures for changes of ownership, transferring the
permit, and renewing the permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system, to record deed restrictions, to transfer the
permit, or to renew the permit, 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 adjudicatory hearing by filing a written petition with the Office of
Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the North
Carolina General Statutes, and must be filed with the OAH within thirty (30) days of receipt of

27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com.
Unless such demands are made this permit shall be final and binding.

manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling
near a wet detention basin or stream, etc.).
The original design depth is: 7'
