Pier 1 Imports
High Density Stormwater Project
Carteret County'
Dear Mr. Hamilton:
The Wilmington Regional Office received a complete Stormwater Management Permit Application for Pier 1
Imports on January 24, 2001. Staff review of the plans and specifications has determined that the project, as
proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H. 1000.. We are forwarding
Permit No. SW8 001125 dated February 16, 2001, for the construction of Pier I Imports.
]'his permit shall be effective from the date of issuance until February 16, 2011, and shall be subject to the
conditions and -limitations as specified therein. Please pay special attention to the Operation and Maintenance
requirements in this pernut. Failure to establish an adequate system for operation 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
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, conforming to Chapter 150B of the North Carolina General Statutes; and filed
with the Off -ice of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 2761 1-7447. Unless such demands
are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact Linda Lewis, or
me at (910) 395-3900.

Maintenance activities shall be performed as follows:
1. After evey significant runoff producing rainfall event and at least monthly::
a. Inspect the wet detention basin system foT sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed. .
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
r
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be -disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin, or stream, etc.). . _..........
a f'
The measuring device used to determine.the• sediment elevationt'shall be such.that it will give an accurate
depth reading and not readily penetrate into accumulated sediments:
When the permanent pool depth reads IS feet in the main pond, the,sedirrient shall be removed. ^.
When the permanent pool depth reads- 25 feet in the forebay, the sediment shall be removed. -
