Athwhinent C €or a detailed description o€the current proposed min modification and a list of all the past
mks moved during the effbative period of the permit. We are forwarding you an approved copy of the

STATE OF NORTH CAROLINA
DEPARTMENT OF ENVIRONMENTAL QUALITY
DIVISION OF ENERGY, MINERAL AND LAND RESOURCES
STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY DEVELOPMENT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
New Hanover County Airport Authority
Wilmington International Airport Extended Dry Detention Basins (EDDB)
1740 Airport Boulevard, Wilmington, New Hanover County
I11C9]9IMIl'.I 0
construction, operation and maintenance of three (3) extended dry detention basin "stormwater control
measures" or "SCM") in compliance with the provisions of 15A NCAC 2H .1000 (1995 Rules) as
amended on January 1, 2017 (p2017 Rules) (collectively, the "stormwater rules') and the approved
stormwater management plans and specifications and other supporting data as attached and on file with
and approved by the Division of Energy, Mineral and Land Resources (the "Division" or "DEMLR")
and considered an enforceable part of this permit.
This permit shall be effective from the date of issuance until June 15, 2027, and shall be subject to the
following specified conditions and limitations:
I. DESIGN STANDARDS
1. The drainage area identified as Phase All is subject to the 1995 Rules and as clarified in the
1995 specific conditions listed herein. The drainage areas identified as Phase IIIA, Phase IIIB
and Phase IIIC are subject to the 1995 Rules and the 2017 Rules and as clarified in the 2017
Rules specific conditions listed herein.
2. This project and SCMs have been approved based on the "Wilmington International Airport
Stormwater Master Plan" document approved on November 24, 2004 as a variation to the
stormwater rules and in accordance with G.S. 143-214.7(c3). All future major modifications to
this permit must either meet the 2004 "Wilmington International Airport Stormwater Master
Plan" in its entirety, meet the most current set of stormwater rules, or provide technical
justification that the proposed modification is providing equal or better control and equal or
better protection of waters of the State as a variation under the current set of stormwater rules.
Approval of such variations that do not meet all of the requirements is done on a case -by -case
basis.
3. FAA requirements prohibit standing water (i.e., permanent pools) and stipulate that the design
storm must be fully drained within 48 hours. This is supported by G.S. 143-214.7(c3) where
the Division does not require the use of an SCM with standing water. The approved SCM
design for the 3 extended dry detention basins includes a low flow device but does not include
a permanent pool at the low flow outlet or sediment storage.
4. The approved "Wilmington International Airport Stormwater Master Plan" document is not
intended to limit or restrict the airport or its current or prospective tenants from pursuing
alternative or modified stormwater management solutions in various locations than those listed
in the document itself. Since the approval of the "Wilmington International Airport Stormwater
Master Plan" document, other stormwater control measure (SCM) options that do not contain
areas of standing water have been developed and should be evaluated for future projects.
Page 1 of 5

State Stormwater Management Systems
Permit No. SW8 050547
5. This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data. The maximum amount of built -upon area (BUA)
allowed for the entire project is 9,304,059 square feet.
6. The three (3) SCMs identified as "Phase I and II" Extended Dry Detention Basin, Phase IIIA
Extended Dry Detention Basin and Phase IIIB Extended Dry Detention Basin have been
designed to handle the runoff from 8,520,835 square feet, 116,598 square feet, and 367,596
square feet of BUA, respectively, within the delineated drainage areas. The BUA for future
development within the drainage areas to the SCMs identifies as "Phase I and 11" Extended
Dry Detention Basin, Phase IIIA Extended Dry Detention Basin and Phase IIIB Extended Dry
Detention Basin is limited to 2,175,154 square feet, 48,788 square feet, and 264,031 square
feet, respectively.
7. Where an individual project within the drainage area is being leased or sold, the stormwater
collection system for that project must be located in either dedicated common areas or
easements and the final plats will be recorded showing all such required easements.
8. The drainage areas for the on -site stormwater systems will be limited to the amounts of built -
upon area indicated in this permit and the approved plans and specifications. The runoff from
all built -upon area within the permitted drainage areas of this project must be directed into the
permitted stormwater control measures.
9. (2017 Rules) The peak flow from the 10-year storm event shall not cause erosion downslope
of the discharge point.
10. (2017 Rules) A 50-foot wide vegetative setback must be provided and maintained in grass or
other vegetation adjacent to all surface waters as shown on the approved plans. The setback
is measured horizontally from the normal pool elevation of impounded structures, from the top
of bank of each side of streams or rivers, and from the mean high waterline of tidal waters,
perpendicular to the shoreline.
11. The portion of the existing airport previously included in the drainage area of the permitted dry
detention basin that is being removed, must be submitted in a future permit application as a
modification or under G.S. 143-214.7(c4).
12. (1995 Rules) The following design criteria have been provided and must be maintained in the
"Phase I and 11" Extended Dry Detention Basin.
Phase I & II
a. Drainage Area, acres: 287.63
Onsite, ft2: 12,529,107

1. Receiving Stream/River Basin: Smith Creek / Cape Fear
M. Stream Index Number: 18-74-63
n. Classification of Water Body: C;Sw
13. (2017 Rules) The SCMs identified as Phase IIIA Extended Dry Detention Basin and Phase IIIB
Extended Dry Detention are permitted based on the design criteria presented in the sealed,
signed and dated supplements, the sealed and signed "Technical Justification" document
dated April 13, 2021 justifying the variations from the Wilmington International Airport
Stormwater Master Plans well as the 2017 minimum design criteria, and as shown in the
approved plans and specifications. These SCMs must be provided and maintained at the
design condition. The approved supplements are incorporated by reference into this permit.
Page 2 of 5

State Stormwater Management Systems
Permit No. SW8 050547
14. (2017 Rules) If the SCMs identified as Phase IIIA Extended Dry Detention Basin and Phase
IIIB Extended Dry Detention are found to not meet the approved design criteria, a modification
must be submitted to either meet the requirements or propose another variation from the rules.
This is based on a case -by -case decision and should not be used as a precedent for future
permitting actions.
15. Tributary projects outside of the drainage area of the previously approved "for -credit" grassed
swales, but inside the drainage area of the approved SCIVIs, must provide an additional BMP
with a sufficient TSS removal efficiency such that the total TSS removal, including the
extended dry detention basin, is at least 85%.

Based on the current guidance to minimize the spread of COVID-ig, the Department of Environmental Quality has adjusted
operations to protect the health and safety of the staff and public. Many employees are working remotely or are on staggered
shifts. To accommodate these staffing changes, all DEQQoffice locations are limiting public access to appointments only. Please
check with the appropriate staff before visiting our offices, as we may be able to handle your requests by phone or email. We
appreciate your patience as we continue to serve the public during this challenging time.
