Subject: Permit No. SW7970407 Renewal
Graveyard of the Atlantic Museum
High Density Stormwater Project
Dare County
Dear Mr. Schwarzer:.
The Washington Regional Office received a completed Stormwater Renewal Application for the subject
project on January 26, 2007. Staff review of the files and an on site inspection has determined that the project will
comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No.
SW7970407 dated June 20, 2007 to the Graveyard of the Atlantic Museum for three infiltration basins to serve
Graveyard of the Atlantic Museum located along the NC 12 spur, just west of NCDOT Ferry Docks, in Hatteras, NC.
This permit shall be effective from the date of issuance until June 20, 2017 and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and Maintenance
requirements in this permit. Failure to establish an adequate system for operation and maintenance of the stormwater
management system will result in future compliance problems. The issuance of this permit does not resolve any
previous violations of the stormwater rules for construction without a permit.
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 Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. 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 Samir
Dumpor or me at [phone].

WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
,,I
Maintenance activities shall be performed as follows: JAN 2 J 2007
1. After every significant runoff producing rainfall event and at least monthly: DWQ-WARC
a. Inspect the wet detention basin system for 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 occur 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 maintains 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.
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.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads feet in the forebay, the sediment shall be removed.
