Subject: Stormwater Permit No. SW7971022 Modification
NC Aquarium on Roanoke Island Building Addtion,
Pier and Storage Building
High Density Project
Dare County
Dear Mr. White:
The Washington Regional Office received a complete Stormwater Management Permit Application for
the modification of North Carolina Aquarium on Roanoke Island Building Addition, Pier and Storage
Building on July 12, 2012. Staff review of the plans and specifications has determined that the
project, as proposed, will comply with the Stormwater Regulations set forth in Session Law 2008-211
and Title 15A NCAC 2H.1000. We are forwarding Permit No. SW7971022MOD dated September 5,
2012, for the construction of the subject project.
This permit shall be effective from the date of issuance until April 18, 2018, 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.
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 Scott
Vinson, or me at [phone].
Sincerely,

RE: NC Aquarium on Roanoke Island
High Density Stormwater Permit Modification SW7971022
Dear Scott:
RECEIVED
JUL 12 2012
DWQ-WARO
Thanks for all your help over the last few months getting me information regarding the existing
Stormwater permit parameters. As we had discussed, the large basin designated Basin #2 on
the existing permit is much larger than was required. For these new additions we will pipe
existing and proposed runoff from a Project Area on the west side of the site to this large basin.
The stormwater from this area currently infiltrates or sheet flows toward the Croatan Sound.
With this modification, we will be, capturing some of this existing run-off as well as the
anticipated runoff from the new coverage. The existing basin #2 has a required capacity of
9,897 cf and an actual capacity of 51,649 cf. We did survey this basin to confirm this volume.
This basin has no outlet and functions completely by infiltration. It appears to function well.
I identified a project area of 18,139 sf, as this appears to be the area that will be captured with
these improvements. This modification will capture all of,the existing runoff within this area as
well as the runoff from the new additions. The attached spreadsheet illustrates that the Pre vs.
Post conditions will dictate the design volume. This has been calculated to be 1,473 cf.
Attached are an application, fee and supporting data. These projects are scheduled to begin
construction in the Fall of this year. We have applied for a CAMA Major permit for the pier which
is currently under review by the Division of Coastal Management. Since this is an existing basin
I assume that the O&M Agreement is already in place so I have not included that form or a
Basin Supplement form with this submittal. If I can provide any additional information, please
dons-#t,sitate to cm act/ e.

Stormwater Narrative DWQ-WARO
SCO Project# 10-08584-01 A& 10-08739-01 A
July 2012
The North Carolina Aquarium on Roanoke Island intends to construct a 1,792 SF
building addition to the main building. This addition will be used for turtle rehabilitation
and educational programs. The Aquarium also intends to construct a 220 foot long
pier with a Gazebo, lower educational platform, fishing areas, and kayak launch in the
Croatan Sound west of the existing Aquarium facility. The pier will be used for
interpretation, educational programs, fishing, special events, and other programs
administered by the NC Aquarium staff and others. The project will also include a
small storage building to contain items used for educational programs, including
kayaks, dip nets, PFD's, paddles, and other program related materials. The project
also includes a sidewalk and paver block areas at the beginning of the pier.
The stormwater that currently falls in this area either infiltrates into the sandy soils or
sheet flows toward the Croatan Sound (SA water). The intent is to install a subsurface
collection system to intercept and convey stormwater from all the proposed additions.
The collection system will also intercept the existing runoff as the project area
currently has existing coverage. The Aquarium has a large infiltration basin with no
outlet to the Sound. The current required volume for this basin is 9,897 cf. The
measured volume of this basin based upon a topographic survey is 51,650 cf. This
basin is well established and appears to functioning properly. The new collection
system will include yard inlets, collection piping and several drop inlets. The new
Turtle Rehabilitation building will have gutters and downspouts which will be piped to
the new drop inlets located west of the new building. The paved area and storage
shed will sheet drain to a shallow swale along the western edge of the project site with
two 18" x 18" yard inlets as illustrated on the plans. This will allow stormwater from this
area to both infiltrate and be conveyed to the existing stormwater basin Tha vnh imp
required to be managed for these additions is 1,473 cf.

Dear Mr. White:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7971022 for stormwater infiltration basins serving the NC
Aquarium located at 374 Airport Road in Manteo, NC expires on April 18, 2018. This is
a reminder that permit renewal applications are due 180 days prior to expiration. We do
not have a record of receiving a renewal application at this time.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Permit application forms for renewal can be found on our website at
http://deq.nc.gov/about/divisions/energy-mineral-land-resources/energy-mineral-land-
ruleslstormwater-programlpost-construction.
North Carolina General Statutes and the Coastal Stormwater rules require that this
property be covered under a stormwater permit. Failure to maintain a permit subjects
the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you.
Sincerely,
M `e ,
