Subject: State Stormwater Management Permit No. SW8 931005
Albert J. Ellis Airport
Deemed Permitted Stormwater Project/Session Law 2012-200
Onslow County
Dear Mr. White:
The Wilmington Regional Office received a complete, modified Stormwater Management Permit
Application for Albert J. Ellis Airport on October 11, 2016. The applicant has certified that the project's
built-upon areas and stormwater treatment have been designed to meet the requirements of Session
Law 2012-200. The applicant has indicated that all existing and proposed parking areas, roads,
taxiways, terminal buildings, runways, aprons, etc., provide for overland flow and that infiltration and
treatment of the stormwater in grassed buffers, shoulders and grass swales is promoted. As such, the
project is deemed permitted pursuant to the State post-construction stormwater requirements. We are
forwarding modified Permit No. SW8 931005 dated October 17, 2016, for the construction of the
deemed permitted built-upon areas associated with the subject project.
The modifications covered by this permit include the construction of 0.50 acres of additional built-upon
area for a storage hangar and apron expansion.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the
conditions and limitations as specified therein, and does not supercede any other agency permit that
may be required. This modification covers the construction of the General Aviation Terminal and Apron.
The approved plans for this modification are added to the previously approved plans.
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. Per
NCGS 143-215(e) the petition must be filed with the OAH within thirty (30) days of receipt of this permit.
You should contact the OAH with all questions regarding the filing fee (if a filing fee is required).and/or
the details of the filing process at 6714 Mail Service Center, Raleigh, NC 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.

PERMISSION IS HEREBY GRANTED TO
Albert J. Ellis Airport Director
Albert J. Ellis Airport
264 Albert J. Ellis Airport Road, Richlands, Onslow County
FOR THE
construction, operation and maintenance of a 30% low density development in
compliance with the provisions of 15A NCAC 2H .1000 (hereafter referred to as the
"stormwaterrules`) and the "deemed permitted" requirements of Session Law 2012-200
for Airports. 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, are considered a part of this permit.
The Permit shall be effective from the date of issuance until rescinded and shall be
subject to the following specific conditions and limitations:
I. DESIGN STANDARDS
1. This permit covers the construction of a total of 129.40 acres of proposed built-
upon area within a 676.88 acre project area. Prior to this modification, there was
99.01 acres of BUA permitted for the Airport. This modification adds 0.50 acres
of built-upon area, resulting in a new permitted BUA amount of 99.51 acres
equivalent to 14.7% of the total site area. This leaves 29.89 acres available for
future development.
2. The overall tract built-upon area percentage for the project must be maintained at
30% or less, as required by Section .1005 of the stormwater rules. The tract is
limited to a maximum of 203.06 acres of built-upon area.
3. Approved plans and specifications for projects covered by this permit are
incorporated by reference and are enforceable parts of the permit.
4. Per Session Law 2012-200, runoff from built-upon areas of the project must be
maintained via overland flow that promotes infiltration and treatment of
stormwater runoff into grassed buffers, shoulders, and grassed swales.
Maximum side slopes shall be 3:1 (H:V) as defined in the stormwater rules and
approved by the Division.
5. No piping is allowed except that as shown on the approved plans.

II. SCHEDULE OF COMPLIANCE
1. Projects covered by this permit will maintain a minimum 30-foot wide vegetative
buffer between all impervious areas and surface waters.
2. The permittee is responsible for verifying that the proposed built-upon area does
not exceed the allowable built-upon area under this permit.
3. The Director may notify the permittee when the permitted site does not meet one
or more of the minimum requirements of the permit. Within the time frame
specified in the notice, the permittee shall submit a written time schedule to the
Director for modifying the site to meet minimum requirements. The permittee
shall provide copies of revised plans and certification in writing to the Director
that the changes have been made.
4. The permittee shall not subdivide and/or sell any portion of the 676.88 acre
project area, in whole or in part, unless and until the Division is notified of the
sale and approval is granted. The new property owner shall be required to submit
for and receive a permit to cover the development of that subdivided property.

Good Afternoon Linda,
I hope this email finds you well and hopefully safe from the rising waters.
I understand your concerns and hopefully, the explanation of my thought process will assist in making a
decision.
Storage Hangar Area
Albert Ellis Airport wants to build additional hangar space, as clients make thems-elves available. In doing so,
the buildings are usually encompassed by an impervious surface around the building. As in this case, the
hangar apron is located on one side with parking facilities on two of the remaining sides; however, it is
anticipated that future permit modifications will include parking facilities for future hangar expansions. Based
on site constraints, surrounding grades, and impervious area, the roof drains cannot utilize overland flow.
Based on the Session Law 2012-200, Senate Bill 229, the design should provide overland flow that promotes
infiltration and treatment of stormwater runoff from the built upon areas into grassed buffers, shoulders, and
grassed swales. The civil Engineers are proposing the collection of roof drains, into perforated pipe, before
discharging to a grassed open conveyance. We are only piping the amount required to get to the open
conveyance. From there, the water flows south then due west, within a grassed open conveyance, to a pipe
crossing under the taxiway and runway, before the final discharge point that is within an open conveyance.
Even though the roof drainage does not collect directly into an open conveyance, once discharged from the
perforated pipe into the open conveyance, the water will flow for approximately 1,230 LF prior to discharging
off of airport property.
In this case, we are trying to also infiltrate by introducing the water straight into the subgrade. This was an
approved method for the previous permit modification, the adjacent General Aviation Terminal Building roof
drain system. I am including the soils map, as submitted within the original permit. I am also including the
excerpt from the geotechnical report, summarizing the groundwater elevations.
soils
The U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS) maps for Onslow County,
North Carolina (see Soils Map, Figure 4) indicate that Goldsboro-Urban land complex mapping unit underlies
the development area. Goldsboro-Urban land complex consists of 50% moderately well-drained Goldsboro
i

soil, about 30% Urban land, and soil that has been disturbed during urban development. Slopes range from 0
to 5 percent. Goldsboro-Urban land complex is hydrologic soil type "B". This soil type has high infiltration
properties.
Groundwater
Geotechnicai reports show groundwater measurements of 0.1 to 7 feet below existing ground and an
estimated seasonal high groundwater table of 1 to 2 feet below existing ground. In the area of the storage
hangar, the site had structural fill brought in to a depth of five to six feet above the existing ground. Therefore,
the perforated pipe location is approximately three to four feet above seasonal high groundwater elevation.
Apron Expansion Area
As mentioned below, an additional perforated pipe and catch basin was added to assist in the 48 hour draw
down, as required by the FAA. Prior to the apron expansion, the water had a shortest flow path of
approximately 150 LF of overland flow, prior to reaching the drainage inlet. As proposed, the shortest flow path
will be approximately 50 LF of overland flow at 1.5-5% slope, prior to reaching the drainage inlet. According to
Chapter 13 Public Airports BMP Toolbox of the NCDENR Stormwater BMP Manual, this width and slope exceed
the minimum requirements for filter strips in North Carolina. The additional pipe and inlet are additional to the
required pipe needed to cross under the roadway. Once out falling from the roadway pipe crossing, the water
will flow in a grassed swale for approximately 2,096 LF prior to discharging off of airport property. The overland
flow and grassed swale provide a treatment train that will both infiltrate and treat stormwater before

I am concerned about the addition of piping, catch basins and the addition of that large hangar area and how that fits

The wording about"other areas" covered by the SL is ambiguous and the SL does not specify what constitutes overland
flow. However, it does require that overland stormwater flow be provided that promotes infiltration AND treatment of
stormwater via grassed buffers, shoulders, and swales permitted pursuant to the State post-construction stormwater
requirements.
The use of perforated piping and overland flow will require you to demonstrate that the soils and water table promote
(or at least allow for) infiltration and that the stormwater that is not infiltrated is treated in grassed buffers,shoulders,
and swales.
What you propose may or may not promote infiltration depending on the soil type and seasonal high water table. Nor
does it describe that there is any treatment of any stormwater occurring in grassed buffers,shoulders, and swales.
Please demonstrate that the proposed design promotes infiltration and that the stormwater is treated in grassed

Revised Geotechnical Engineering Report SWE Project No. 1306-14-002
General Aviation Terminal and Apron,Albert J. Ellis Airport,Jacksonville, NC April 17,2014
4.4 CPT Soundings
The CPT soundings performed for this exploration(5-01 thru 5-14 and S-04AO were
extended to depths ranging from approximately 5.6 to 45.1 feet below the existing ground
surface. Two of the CPT soundings encountered shallow refusal at depths of 6 feet and 5.6
feet below the existing ground surface. The strata interpreted from the CPT soundings
represent approximate boundaries between soil behavior types'. Based on the results of
the CPT soundings,seven general soil strata were encountered within the maximum
exploration depth of 45.1 feet. The strata are briefly described in the following table.

4.5 Groundwater
Groundwater was encountered at all eight hand auger boring locations and ranged in
depth from about 0.7 to 4.3 feet below the existing ground surface. Estimated
groundwater depths at the CPT sounding locations ranged from approximately 2.5to 5
feet below the existing ground surface. It is important to note that groundwater
elevations will fluctuate with seasonal factors, including rainfall, evaporation, and other
factors.
'Soil Behavior Type is calculated based on empirical correlations which use the three fundamental
penetrometer measurements(i.e.,tip resistance,sleeve friction,and pore pressure). A CPT may define a
soil based on its behavior as one type,while its grain size and plasticity(the traditional basis for soil
classification)may define it as a different type.

Subject: FW: ON Stormwater Permit Information
I'm having a bit of trouble with the Airport Session law and determining what meets it and what
doesn't. See the sketches embedded in the email below. We had previously approved some BUA
additions to the Albert Ellis Airport under the Session Law, but apparently the contractor decided that
the area wasn't draining within the 48 hours as required by the FAA and added some additional catch
basins and perforated piping without any Division approval. I don't think this qualifies as meeting the
sheet flow requirement.
My take on this is that the "sheet flow" referred to in the SL is intended to be that the runoff from the
runways and taxiways will sheet flow off tand then go over vegetated areas and into vegetated
ditches. It was not intended to allow sheet flow over a paved area and then to dump that sheet flow
across a few feet of grassed slope and then into a proposed or an existing piped collection system.
This appears to be the way Albert Ellis' design consultants have approached meeting the SL for all of
their construction at Albert Ellis, not just runways and taxiways. I feel powerless to stop them because
of the ambiguous wording about "other areas" covered by the SL and because there is no set amount
of grassed area to sheet flow over specified in the SL
At Albert Ellis, they keep adding more BUA for hangar builders, not runways or taxiways, clustered
into areas that are already high density that have a bunch of existing piped collection systems that
they just keep extending as they add more BUA. They insist it is in keeping with the SL because they
use perforated piping and they allow for a little bit of overland sheet-flow and/or conveyance in a short
grassed swale before the runoff is picked up by a drop inlet and extended piped collection system.
I'm leaning toward requiring them to design and permit the perforated piping as an infiltration trench.

The additional 18" perforated pipe and inlet was installed by the contractor at their discretion. The reason for
the additional pipe was the "flat/minimal grades" located to the right of the utility corridor (blue line). The
utility corridor was located shallower than anticipated due to the minimal required slopes, utility separation,
and minimal cover required. This did not allow for this area to drain within the required 48 hour period, as
required by the FAA. The contractor installed the perforated pipe, as per the approved BMP items for this
project.
As you can see, the piping is only to collect from the drainage basin and cross under the road to the existing
open conveyance system. It does not enter a closed system after the discharge. I apologize that this is the first
you have seen of it.
For the permit revision just submitted, no new revisions will be made to the perforated pipe or inlet.

For Item #2, as stated in the NCDENR State Stormwater Permit Modification for Permit No. SW8 931005 dated
January 29, 2015,4.45 acres were approved for the new permitted BUA amount. As mentioned during
yesterday's meeting, both the narrative and the area calculations do not clearly identify the BUA breakdown.
Please allow the following table to clarify the original permit modification revision sub areas equaling the 4.45
acre approval:
Area
Area Description Area ft Acre
Demolished BUA(roads) 5,638 0.13
New Apron 115,030 2.64
Apron Extension 22,068 0.51
Terminal Building 6,619 0.15
Sidewalk Left 868 0.02
Sidewalk Right 3,389 0.08
Parking Lots & Roads 36,538 0.84
Small Rd Portion 2,200 0.05
Fuel Truck Parking 1,964 0.05
Concrete Pad 1,180 0.03
Proposed Hangar by others 9,500 o.22
Total Permitted 193,721.92 4.45
Even though it was not shown adequately, it was intended that the open area, left of the terminal building, is
ultimately impervious area. This currently permit revision needs an additional 6,098.4 ft2 (0.14 acres) to fully
permit this building location. The remaining 0.36 acres for a total of 0.50 acres, is for the apron expansion, as
depicted in the permit revision plans.
I hope this clarifies the issues at hand. Please feel free to contact me with any further clarifications or questions.

Hello-
Just checking in to see if you were able to locate the approved plans for that existing pipe and
whether or not you've been able to determine if the 4.45 acres of BUA approved in January 2015
included that building that wasn't very clearly marked as a future building?
will check on the applicability of a review for compliance with SL 2012-200 for any addition of
property to the existing airport.

The proposed project consists of an apron expansion of the existing terminal apron and a storage
hangar near the existing General Aviation terminal and apron. The proposed project will add 0.50
acres of Built-Upon Area(BUA) for a total of 99.51 acres of BUA that will exist at the airport upon
project completion. This does not exceed the maximum amount of permitted BUA of 129.40 acres
at the airport. Refer to Table 1 for project and airport BUA amounts.

Note that an assumed BUA for the storage hangar was included in the plan revision permit
modification associated with the General Aviation (GA) Terminal and Apron project, approved on
January 29, 2015. Based on final design of the storage hangar, the additional BUA as a result of
the project is 0.14 acres.The proposed BUA for the apron expansion is 0.36 acres. This results in
a total added RUA of 0.50 acres for this plan revision.

ALBERT J. ELLIS AIRPORT RSW
Apron Expansion and Storage Hangar
State Stormwater Management Permit No. SW8 931005 Plan Revision
Permit Approach
This project is a plan revision to Stato Stormvater Management Permit Nc. SW8 931005 issued
on May 2, 2013. Per Section 11.10.e of permit No. SW8 931005, this project is development of the
designated future development areas. Refer to Figure 2 Albert J. Ellis Airport Proposed& Future
Development Phases as submitted with the permit modification approved on May 2, 2013. The
apron expansion and storage hangar locations are shown in Figure 2. All runoff from the apron
expansion built-upon area flows over grassed buffers/shoulders and into existing grassed swales.
Existing swale side slopes are maintained at 3:1 or flatter. All runoff surrounding the storage
hangar will sheet flow away from the hangar. Due to site constraints, roof drains from the building
cannot utilize overland flow. Instead, the design utilizes a perforated underdrain system to allow
exfiltration into the existing soils and treatment of the roof drainage. This is very similar to the
system permitted for the General Aviation Terminal building roof drainage. There are no other
underground piping systems.
The proposed project meets the requirements of Session Law 2012-200, Senate Bill 229. The
design provides overland flow that promotes infiltration and treatment of stormwater runoff from
the built upon areas into grassed buffers, shoulders, and grassed swales. No built upon areas are
directly connected to a pipe system without first utilizing overland flow or underdrain exfiltration.
The natural flow paths and outfalls of the project are preserved in the proposed design. The
proposed projoct utilizes Best Management Practices (BMPs) identified in Chapter 13 for Airports
in the DENR BMP manual. Those BMPs are:
• Disconnected Impervious Area/Overland flow
Disconnected Impervious Area/Overland Flow — The proposed site was graded to match
existing grades and slopes as much as possible. Most slopes are less than 3%. This BMP is
utilized for stormwater runoff from the BUA associated with all surfaces. Research has shown that
the majority of the pollutant removal occurs in the first 8 feet of overland flow. For all surfaces, at
least 20 feet of overland flow has been provided between the BUA and the existing open
conveyance. Maintenance of this area consists of routine maintenance and preservation of the
stand of grass.
Conclusion
The proposed Apron Expansion and Storage Hangar project is revising State Stormwater
Management Permit No. SW8 931005 by adding 0.50 acres of BUA. The proposed project
complies with the requirements of Session Law 2012-200, Senate Bill 229, which allows for the
proposed activities to be deemed permitted.

No. 150/5200-33B (Hazardous Wildlife Attractants on or Near Airports),the Department shall not
require the use of stormwater retention ponds, stormwater detention ponds, or any other stormwater
control measure that promotes standing water in order to comply with this section at public airports
that support commercial air carriers or general aviation services. Development projects located
within five statute miles from the farthest edge of an airport air operations area, as that term is
defined in 14 C.F.R. § 153.3 (July 2011 Edition), shall not be required to use stormwater retention
ponds, stormwater detention ponds, or any other stormwater control measure that promotes standing
water in order to comply with this section. Existing stormwater retention ponds, stormwater detention
ponds, or any other stormwater control measure that promotes standing water in order to comply with
this section located at public airports or that are within five statute miles from the farthest edge of an
airport operations area may be replaced with alternative measures included in the Division of Water
Quality's Best Management Practice Manual chapter on airports. In order to be approved by the
Department, alternative measures or management designs that are not expressly included in the
Division of Water Quality's Best Management Practice Manual shall provide for equal or better
stormwater control based on the pre-and post-development hydrograph.Any replacement of existing
stormwater retention ponds, stormwater detention ponds, or any other stormwater control measure
that promotes standing water shall be considered a minor modification to the State general .
stormwater permit.
(c4)The Department shall deem runways,taxiways, and any other areas that provide for overland
stormwater flow that promote infiltration and treatment of stormwater into grassed buffers,
shoulders, and grass swales permitted pursuant to the State post-construction stormwater
requirements."

Overland Flow
Overland flow of stormwater runoff from runways,taxiways, and other impervious surface such
as rooftops, hangers, and parking lot allows a significant portion of the run-off to be filtered and
infiltrate;thus reducing both pollution and peak flows.

NCDENR Stormwater BMP Manual Chapter revised 10-1-12
Soil amendments may be utilized in conjunction with either vegetative filter strips, or grassed
swales. Soil amendments typically increase infiltration rates by introducing coarse-grained,
washed sand amendments into the in-situ soil. Soil amendments will improve infiltration by
increasing soil pore spacd near the surface. Soil amendments are typically installed by tilling
sand-size particles into the existing soil up to a depth of 12 to 18 inches. A backhoe (or similar
shovel-based machine)may be utilized.An under drain can be included in the design to allow
the soil to drain between storm events. Soil amendments can be sized to provide volume control,
depending on the ratio of impervious area to the area that receives the stormwater runoff. If soil
amendments are incorporated,they should be considered as a supplement to, or performance
enhancer for, filter strips and swales.
13.8 Low Density Projects (T15A: 02H .1003 (d)(1))
Projects permitted as low density projects must be designed to meet and maintain the applicable
low density requirements specified in T15A: 02H .1005 through .1007. Under the current Phase
II and Coastal Rules (Session Law 2008-211 and Session Law 2006-246), a project with an
overall density at or below the low density thresholds, but containing areas with a density greater
than the overall project density,may be considered low density as long as the project meets or
exceeds the following post-construction model practices for low density projects mandated in
Session Law 2006-246 and 2008-211:
• Use vegetated conveyances to the maximum extent practicable to transport stormwater
runoff. Pipe conveyance is minimized.
• Locates the higher density areas are located away from surface waters and drainage ways
to the maximum extent practicable, i.e., disconnects surfaces,promotes infiltration, sheet
flow, and overland flow, and lengthening flow paths to the maximum extent practicable.
• Stormwater runoff from built upon areas that is directed to flow through any wetlands
shall flow into and through these wetlands at a non-erosive velocity
Development designed to meet the low density requirements must demonstrate that no areas
within the project site are of such high density that stormwater runoff threatens water quality.
13.9 High Density Projects (T15A: 02H.1003 (d)(2))
Projects permitted as high density projects must be designed to meet the applicable high density
requirements specified in 02H .1005 through 02H .1008. Paragraph (c)(5) does allow for other
designs if these designs are shown by the applicant,to the satisfaction of the Director,to provide
equivalent protection.
Also, under 02H .1008 (h) stormwater management systems consisting of other control options
or.series of control options may be approved by the Director on a case-by-case basis where the
applicant can demonstrate that the Alternative Design Criteria provides equal or better
stormwater control, equal or better protection of waters of the state, and result in no increased
potential for nuisance conditions.

Thank you, Linda. We are preparing the express review plan revision. Can you confirm who we make the check
payable to? The application form still says NCDENR, but we weren't sure if that should be NCDEQ.

Sorry, that is the classic definition of what a plan revision is. You're not modifying the permit, but if the
"as-built" project differs in some way from the approved condition, then you will need to submit a
completed plan revision application form, a narrative of the changes, and 2 sets of revised plans.
Thank you.

Subject: Project under Permit No. SW8 931005
Linda,
At Albert J. Ellis Airport, a hangar associated with the General Aviation (GA) Terminal and Apron plans and
permit is moving forward (see attached PDF). For the GA Terminal,we did a plan revision to the State
Stormwater Management Permit No. SW8 931005, which included anticipated BUA for the proposed hangar
(see attached PDF). The actual design of the new hangar has resulted in -0.1 acre more than we had included
in the BUA for the GA Terminal plan revision.
All stormwater runoff surrounding the hangar will sheet flow away from the hangar. Due to site constraints,
roof drains from the building cannot utilize overland flow. Instead, the design utilizes a perforated underdrain
system to allow exfiltration into the existing soils and treatment of the roof drainage. This is very similar to the
system permitted for the GA Terminal building roof drainage. There are no other underground piping systems.
We are anticipating that a plan revision will not be required for this hangar because the BUA was included in
the GA Terminal and Apron plan revision and the proposed project meets the requirements of the permit.
Please confirm this strategy.
Thank you,
Lindsey Marion, PE, CFM
