Dear Mr. White:
The Wilmington Regional Office received a complete, modified Stormwater Management Permit
Application for Albert J. Ellis Airport on April 25, 2019. 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 of runoff 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 April 29,
2019,for the construction of the deemed permitted built-upon areas associated with the subject

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The Permit shall be effective from the date of issuance until rescinded and shall be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
99.51 acres of BUA permitted for the Airport. This modification adds 1.90 acres
of built-upon area, resulting in a new permitted BUA amount of 101.41 acres
equivalent to 19.12% of the total site area. This leaves 27.99 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, runways, taxiways and any other areas that provide
for overland stormwater flow that promotes infiltration and treatment of
stormwater into grassed buffers, shoulders and grass swales, are deemed
permitted. All built-upon areas of the project must be maintained to meet the
requirements of SL 2012-200.
5. Maximum side slopes for all grassed swales shall be 3:1 (H:V) as defined in the
stormwater rules and approved by the Division.

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 a modified permit application is submitted and approved. The new
property owner shall be required to submit for and receive a permit to cover the
development of that subdivided property.

The existing General Aviation (GA) terminal apron was constructed in 2015.The proposed project includes
grading, installation of drainage structures, installation of site utilities, and construction of airfield
pavement. Construction plans for the proposed project are included in Appendix B.
The proposed project will add 1.90 acres of Built-Upon Area (BUA)for a total of 101.41 acres of BUA that
will exist at the airport upon project completion.This does not exceed the maximum amount of permitted
BUA of 129.50 acres at the airport. Refer to Table 1 for project and airport BUA amounts.

1.2 PERMIT APPROACH
This project is a major modification to State Stormwater Management Permit No. 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 in Appendix A Albert J. Ellis Airport Proposed & Future
Development Phases as submitted with the permit modification approved on May 2, 2013. Runoff from

the built-upon areas of the project flows over grassed buffers/shoulders and into grassed swales to the
maximum extent practicable. Pipes are only proposed to convey flow under roadways/driveways.The
swale side slopes are maintained at 3:1 or flatter.
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 to the maximum extent practical. No built upon
areas are directly connected to the pipe system.The one inlet located within the apron limits discharges in
to the existing swale. The natural flow paths and outfalls of the project are preserved in the proposed
design. The proposed project utilizes several Best Management Practices (BMPs) identified in Chapter 13
for Airports in the DENR BMP manual.Those BMP's are:
Disconnected Impervious Area/Overland Flow
Open Grassed Swales
1.2.1 Disconnected Impervious Area/Overland Flow
FAA grading criteria governs the width and slope of the areas immediately adjacent to runways,taxiways
and aprons. These areas, known as shoulders and safety areas, are relatively flat(less than 3%)and in
most cases wider than the area flowing to them. This BMP is utilized for stormwater runoff from the BUA
associated with the proposed aircraft apron.This idea has also been extended to the roadways and
parking areas wherever possible. Research has shown that the majority of the pollutant removal occurs in
the first 8 feet of overland flow. For the extension of the access roadway and parking lots where feasible,
a minimum of 8 feet of overland flow has been provided between the impervious area and the open
conveyance. Maintenance of this area consists of routine maintenance and preservation of the stand of
grass.
1.2.2 Open Grassed Swales
This BMP has been utilized to the maximum extent possible within the project area. Grassed swales have
been shown to be effective at removing pollutants and suspended solids from average storm events. This
BMP has been utilized between the access roadway and the proposed hangar, between the existing
hangar and the proposed hangar, and between the proposed apron and the existing taxiway.
Maintenance of these features consists of routine mowing and removal of trash and other debris.
1.3 CONCLUSION
The proposed General Aviation Apron Expansion project is revising State Stormwater Management Permit
No.SW8 931005 by adding 1.90 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.

Subject: Airport Session Law
Hey Jeanette.-
I'm not sure who to direct my questions to about implementing the airport session law, so please feel
free to forward this to the right person.
I have an existing airport, Albert Ellis in Onslow County. They hold a low density permit 931005,
issued before the SL came into being. I've been struggling with how to permit new development at the
airport after the SL was passed. I've simply been keeping track of the BUA to keep it under the low
density threshold on an overall basis, and reviewing the individual project for compliance with the
Session Law. The Session Law does not provide a lot of detail, so I always have concerns about
whether a proposed design that falls short in some ways, but exceeds in other ways, meets the intent
of the Session Law or not.
My biggest problem with the SL is the ability for"other areas" of the airport to be deemed permitted,
including passenger parking lots and buildings. As with most airports, the runways and taxiways are
mostly out in the open where sheet flow is easily attained. The "other areas" like buildings and
parking lots tend to be clustered together away from the runway, where one could make the case that
the development is essentially high density if one were to look at it on a master plan level, instead of
an individual project level.
The Airport Chapter in the SCM design manual basically says that if the project cannot meet the
Disconnected Impervious Surface MDC, a permit is required. MDC #2 says that disconnected
pavement must be less than 100 feet in the direction of flow. The most recent proposal at this Airport
is to add a large apron that is 300 feet in the direction of flow. The vegetated receiving area must be
of minimum of 10 feet in the direction of flow. The proposed vegetated receiving area is 50 feet. If 10
feet of vegetated area is enough for 100 feet of paved area, is 50 feet enough for 300 feet?
The proposed vegetated area has a pipe running under it, to transport drainage from the adjacent
project through to the other side, and a yard inlet to allow the drainage from that 300 feet of pavement
to sheet flow through the grassed area, but to ultimately end up collected into the pipe.
The proposal also includes a separate 54" pipe to allow drainage from the offsite areas to bypass
around this new building site. If the offsite area contains past development that was deemed
permitted under the SL, how would the-addition of a 54" pipe to convey runoff affect that deemed
permitted status? Most of this airport development is taking place in a linear fashion, with the new
development being added to the open area adjacent to existing buildings, hangars, and aprons. As
each development is constructed, piping is added to deal with the runoff from the existing projects,
which would appear to put the status of those existing deemed permitted projects in jeopardy.
This 54" pipe runs under the grassed areas on 2 sides of the proposed building. The design plan calls
for the proposed building roof drains to dump onto the ground and sheet flow through the grass, and
i

then dump into the 54" pipe via a yard inlet. Does that meet the intent of the session law? Was it
intended to provide sheet flow for a short distance just to end up collected into a pipe?
So the project proposes some sheet flow (good), but it also proposes extensive piping (bad). Thanks
for any help and direction you can provide.

In the proposed project, we are constructing new pavement along the west side the existing apron (General
Aviation Terminal and Apron, approved on January 29, 2015) where grass previously existed. This grassed area
i

was not used for the Overland Flow t,-eatment of that existing pavement. The slope of that existing apron sheet
fiokvs stornivvater rulnoff toward the north edge of the apron to a grassed area necessary for Overland Flow
treatment. This grassed area is not being affected by the proposed project. The parking lot and adjacent Wright
Brothers Way road sheet flour s"torn iwater to the south end onto the grassed shoulder. The proposed extension
of Wright Brothers Way ccrtinues that flow pattern and does not impede or modify any of the existing grassed
shoulder of the paves' -^ad. The roof drain runoff for the hangar that was approved on October 17, 2016 as
cart of the Storage Hangar and Apron Expansion project will remain as is and not be affected by the proposed

One more change. I thought we discussed at our meeting on March 28, 2019 that the minor
modification 1 plan revision fee in Express is $500.00, not $1000.00. You will need to provide a new
check for $500.00 since we are unable to carry over the unused balance.

AII:
I received the materials associated with the subject project on April 12, 2019, but have not been able
to accept them for review in the Express program yet. All of the previous projects "deemed permitted"
at Albert Ellis since May 2013, have provided a copy of a color-coded master plan which shows all
the existing and proposed development for the airport in phases. This helps to address the deemed
permitted status for the airport as a whole.
think I have cleared up some of the confusion regarding the practical implementation of SL 200-
2012 for Airports to be "deemed permitted." The deemed permitted status applies to the entire
airport, so as each new project is developed, it is the applicant's responsibility to demonstrate that the
conditions under which the previous projects were deemed permitted have not changed and will not
change as a result of the new project. For example, if the
January 29, 2015 Aviation Terminal and Apron project utilized adjacent grassed area for sheet flow of
runoff, but the October 17, 2016 Storage Hangar and Apron Expansion project was developed on top
of that grassed area, then the Aviation Terminal and Apron project would no longer have "deemed
permitted" status.
For Albert Ellis, the first permit which mentioned SL 200-2012 is dated May 2, 2013 for a new terminal
aircraft parking apron and Landside Access Roads (Phase 1).
Next, came the Aviation Terminal and Apron on January 29, 2015, followed quickly by the Rental Car
Service Center on February 27, 2015.
The last project was approved on October 17, 2016 for a Storage Hangar and Apron Expansion.
The current proposal is for a General Aviation Apron Expansion.
Each of these previously approved projects individually met the deemed permitted requirement, but
the airport as a whole also needs to demonstrate that it still meets the Session Law requirements to
be deemed permitted.

MEETING MINUTES
Project: Albert J. Ellis General Aviation Apron Expansion
Subject: NCDEQ Express Stormwater Permit Review Initial Meeting
Date and Time: March 28, 2019 @ 10:00 a.m. NC DEQ Wilmington Office
RS&H explained the project, a proposed expansion south of the existing General Aviation Apron and a
new hangar including grading and drainage improvements and utility extensions. They also summarized
the previous projects and permits, with the most recent being a Plan Revision to the existing overall
airport low density permit, SW8 931005,for the Terminal Apron Expansion and Hangar project. RS&H
asked how they should proceed with permitting this project and future projects. DEQ directed that for
projects that classify as low density and meet the"deemed permitted" qualifications, a Minor Modification
application should be submitted. This is in place of the Plan Revision application which was used
previously but is no longer in use.
DEQ reviewed the proposed Major Modification application that RS&H had prepared and requested that
sheet 3 be updated and included in the new Minor Modification application because it contained the
table summary of BUA quantities.
DEQ requested that RS&H submit a full-size copy of the proposed Master Plan for their records, and
clarified that they do not need the"Safety and Security` sheet nor the"Horizontal and Vertical Control"
sheet in the plans. DEQ requested that dimensions be added to the geometry plan (C201)to calculate and
confirm the BUA quantity in the application.They also requested that the Typical Sections sheet be added
to the plans that will be submitted.
The impervious sheet flow along the apron is greater than the 100' maximum per the stormwater design
manual, but the vegetated receiving area is 50'to 200'which is greater than the 10' minimum. DEQ will
consult with the Raleigh division and get direction on whether this is acceptable.
RS&H shall complete a Minor Modification application and include page 3 from the Major Modification
application which contains the table summarizing the BUA quantities. RS&H will also get a new check for
$1,000 from the Airport and make the discussed changes to the plans. Once the Wilmington DEQ office
receives direction from the Raleigh office, they will convey this information to RS&H and set a "mail in"
date for RS&H to send in these documents.This mail in date will be the start of the 30 day review period.

Stormwater Management at Public Airports
Public airports throughout North Carolina continue to develop to meet the needs of the
expanding population of the state. Public airport expansions include the addition of newly
constructed'hangars,terminal building expansions, runway extensions, and construction of new
taxiways and apron or ramp areas.
Wildlife Hazards at Airports
Wildlife, including birds and mammals, is a threat to human safety during takeoff and landing,
and stormwater BMPs must not increase that threat. Stormwater BMPs should be selected and
designed, constructed and maintained to minimize habitat and associated risks.
Airports are different from other industrial or commercial sites, and must manage stormwater in
a way that will not compromise aircraft safety. Many traditional stormwater BMPs promote
standing water, and attract wildlife that may be hazardous to aircraft. Therefore, some BMPs
must be altered for use in the airport environment, or eliminated all together.
Flight safety must be the first priority at airports. Wildlife, including rodents, larger mammals,
and birds,pose a threat to the safety of flight; while wildlife strikes are not common when
compared to the number of daily flights in the U.S. (around 40,000 flights/day), it only takes one
major incident to cause loss of human life. Between 1990 and 2005, over 66,000 incidents
occurred between wildlife and civil aircraft. In 1990, about 1,700 wildlife strikes occurred,
while in 2005 over 7,000 strikes were reported(FAA, 2010). The majority of wildlife strikes
between 1990 and 2000 involved birds,with 2,395 bird strikes and 443 mammalian strikes
causing damage to aircraft (FAA, 2010). Of non-rodent mammals that were struck, 94 percent
were deer and five percent were carnivores. This is most likely due to the burgeoning U.S. deer
population, which has increased from 350,000 in 1900 to approximately 20 million in 2010
(Curtis and Sullivan, 2001). The most hazardous bird species are those with the greatest body
mass, including vultures, geese,pelicans, cranes, and eagles. The Canada goose exists nearly
everywhere in North Carolina, as many populations have become permanent residents. This
species prefers close-cropped grasses and open bodies of water, which are commonly found at or
near some airports.
Natural landscape portions of the airport environment provide food, shelter, and a travel corridor
for wildlife. Indirect hazards, such as mice, rabbits, and groundhogs, forage in the grassy areas
around the airport. These species attract direct hazards, such as raptors and coyotes,to the
airport, which can cause significant damage to aircraft. When stormwater practices that impound
water for extended periods are installed,they provide a refuge for birdlife. The presence of
multiple wetlands or wet detention ponds at an airport provides travel.corridors for birds that
often cross runways. Since 73 percent of wildlife strikes occur at altitudes of 500 ft above
ground level or less, reducing or eliminating wet detention ponds and wetlands on an airport
would substantially reduce the odds of a bird strike (ALPA, 2009). Another important factor in
bird strikes is the decreased engine redundancy on commercial aircraft in the U.S. fleet; 75
percent of aircraft had 3-4 engines in 1969,while only 10 percent of commercial airplanes have
more than 2 engines today (Wenning et al., 2004). This means that losing one engine has a

t
larger impact on the ability of the airplane to stay airborne. Thus, stormwater features selected
for use at airports must not be attractants to wildlife. All engineering and maintenance decisions
at airports, including those related to stormwater management, must consider wildlife hazards in
order to provide an environment conducive to safe flight.
Stormwater Permitting at Airports
Pursuant to G.S. 143-214.7,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. Further, 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 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. Applicants are encouraged to work with airports to utilize BMPs that
do not promote standing water in or around airports. Any replacement of existing stormwater
control measure that promotes standing water shall be considered a minor modification to the
State stormwater permit.
Pursuant to SB 229,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 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. The
criteria for overland flow specified in the DWQ BMP Manual, includes considerations-for the
seasonal high water table (SHWT), soil type, and soil amendments.
Engineered Best Management Practices (BMPs)
The BMP toolbox for public airports,presented in the DWQ BMP Manual, includes benefits,
costs, maintenance, and potential drawbacks associated with each BMP type. The functionality
of these stormwater BMPs will depend to a large extent on the soil type and the location of the
SHWT. Provided the SHWT is not restrictive, infiltration BMPs, such as bioretention,
infiltration trenches, and filter strips will function best for water quality and hydrologic
improvements in a sandy-type soil. Clayey soils lead to reduced infiltration rates,resulting in
larger required infiltration areas and/or amended soils.
While amended soils may be required to improve infiltration or where minimum distances and/or
slopes cannot be achieved, in a runway safety area(RSA) soils must be compacted to ensure
safety (FAA Specification P-152, FAA 2009) and soil amendments may only be utilized in the
uppermost four inches of the soil. The RSA width can vary from 120 to 500 feet (FAA, 1989).

Development Phases as submitted with the permit modification approved on May 2, 2013. Runoff from
the built-upon areas of the project flows over grassed buffers/shoulders and into grassed swales to the
maximum extent practicable. Pipes are only proposed to convey flow under roadways/driveways.The
Swale side slopes are maintained at 3:1 or flatter.
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 to the maximum extent practical. No built upon
areas are directly connected to the pipe system.The one inlet located within the apron limits discharges in
to the existing swale.The natural flow paths and outfalls of the project are preserved in the proposed
design.The proposed project utilizes several Best Management Practices (BMPs) identified in Chapter 13
for Airports in the DENR BMP manual.Those BMP's are:
Disconnected Impervious Area/Overland Flow
Open Grassed Swales
1.2.1 Disconnected Impervious Area/Overland Flow
FAA grading criteria governs the width and slope of the areas immediately adjacent to runways,taxiways
and aprons. These areas, known as shoulders and safety areas, are relatively flat(less than 3%) and in
most cases wider than the area flowing to them. This BMP is utilized for stormwater runoff from the BUA
associated with the proposed aircraft apron.This idea has also been extended to the roadways and
parking areas wherever possible. Research has shown that the majority of the pollutant removal occurs in
the first 8 feet of overland flow. For the extension of the access roadway and parking lots where feasible,
a minimum of 8 feet of overland flow has been provided between the impervious area and the open
conveyance. Maintenance of this area consists of routine maintenance and preservation of the stand of
grass.
1.2.2 Open Grassed Swales
This BMP has been utilized to the maximum extent possible within the project area. Grassed swales have
been shown to be effective at removing pollutants and suspended solids from average storm events. This
BMP has been utilized between the access roadway and the proposed hangar, between the existing
hangar and the proposed hangar, and between the proposed apron and the existing taxiway.
Maintenance of these features consists of routine mowing and removal of trash and other debris.
1.3 CONCLUSION
The proposed General Aviation Apron Expansion project is revising State Stormwater Management Permit
No. SW8 931005 by adding 1.90 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.

MEMORANDUM:
Date: April 25, 2019
To: Linda Lewis
From: Stephen Rich
Subject: Albert J. Ellis,`-airport General Aviation Apron Expansion
The current Stormwater Permit for Albert J Ellis Airport, SW8 931005,was issued on May 2, 2013 vk.,hen the
original low density permit was converted to meet the deemed permitted I equirements for Airports under
Session Law 2012-200 and the High Density permit#SW8 000810 was consolidated into the one SW8
931005 permit. Since this permit v:,as issued, there have been three Plan Revisions submitted and
approved for the Permit.The table below summarizes these Plan Revisions.
Project Name Project Approval Date
GA Terminal and Apron January 29, 2015
Rental Car Service Center Site Prep February 27, 2015
Apron Expansion and Hangar October 17, 2016
The proposed project, General Aviation Apron Expansion, is adjacent to the apron constructed in the GA
Terminal and Apron project, and near the hangar that was part of the Apron Expansion and Hangar
project. It is not in the vicinity of the Rental Car Service Center Site Prep.
The GA Terminal and Apron project was deemed permitted because it met the necessary requirements for
Overland Flow Treatment off the north end of the apron. See Figure 1 below from the permit drawings of
that project.The grass on the west side of the apron was not used for treatment.

The proposed expansion to this apron is adjacent to the existing apron on the west sic!e, and does not
alter the stormwater flow patterns along the existing apron nor the overland`low area that was necessary
for that apron to be deemed permitted. Figure 2 below is from the permit drawings of the propooscd

Subject: RE: [External] Permit No. SW8 931005 Modification - OAJ Airport
All:
Per NCGS '4ak--214.7(c4), Airports are deemed permitted, and individual projects within the Airport do
not require a review or a permit, as long as the p,oject follows the appropriate requirements in the
statute cited above. The statute says that runways, taxiways, and.any other areas that provide for
aveda.id s4tormwater flow, promote infiltration and treatment of stormwater into grassed buffers,
shoulders, and grassed swales, shall be deemed permitted.
Based on the site plan you provided, there is no "overland" stormwater flow - there is only flow across
an inipervious surface. In addition, there is a LOT of piping proposed. Neither of these things meet
the "deemed permitted" requirements.
This would be a major modification to the low density permit reviewable in express for $2000.00, or in
the Standard program for $505.00. Please note that under low density, the over-pavement flow and
all that piping would be prohibited, as well.

Ms. Lewis,
I hope this email finds you well. We are preparing a permit modification to the State Stormwater Permit No.
SW8 931005 for Low Density Development at Albert J. Ellis Airport (OAJ) in Richlands, NC. This modification will
add 1.9 acres of built upon area (BUA) to the overall permitted airport BUA for an apron expansion. Excerpts
from the application and design plans are attached for your reference. To the maximum extent practicable, the
design is utilizing overland flow that promotes infiltration and treatment of runoff into grassed buffers,
shoulders, and grassed swales. Piping is minimized as much as practicable.
In the past, we have done the "plan revision" application form. Does this still exist? I didn't see it on the
website. Or would this be a major or minor modification?
i

We are planning to do the Express permitting option. Do you allow a pre-application meeting via a
conference/web call? I can share screen and go through the project elements.
Looking forward to working with you on this project.
Thanks,
Lindsey Maron

GENERAL ASSEMBLY OF NORTH CAROLINA
SESSION 2011
SESSION LAW 2012-200
SENATE BILL 229
PART VI. DIRECT THE DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES TO ACCEPT
ALTERNATIVE MEASURES OF STORMWATER CONTROL AT PUBLIC AIRPORTS
SECTION 6. G.S. 143-214.7 is amended by adding two new subsections to read:
"(6) In accordance with the Federal Aviation Administration August 28, 2007, Advisory Circular
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."

I I

Deemed Permitted
The state would not require a local government to require a permit (or other approval)for
airport runways, taxiways, and any other areas that provide for overland storm%r!ater flow that
promote infiltration and treatment of stormwater into grassed buffers, shoulders, and grass
swales. The local government certainly can require more stringent requirements than those
that would be required (or not required) by the state.
Even when deemed permitted,to establish a paper trail, DWQ encourages the airports to
submit the drawings and document that the State concurs should any questions arise regarding
compliance 5 to 10 years down the road.
Overland Flow
While SB 229 did not define overland flow, the applicant could demonstrate overland flow by
demonstrating that 1)the areas that receive stormwater runoff from impervious surfaces will
maintain 80%vegetation coverage or greater, 2) stormwater runoff will be evenly distributed
over the receiving area, 3) the receiving area will be graded to avoid reconnection of run-off to
an impervious surface, to a drainage way or a piped conveyance,4)the contributing impervious
area and the areas that receive stormwater runoff from impervious surfaces is similar in length
and width, i.e.,the receiving green space for a 12 foot wide road should run the length of the
road and be approximately 12 feet wide as well, and 5)to ensure pollutants present in
stormwater is effectively mitigated the minimum distance the stormwater runoff travels is 12
feet for slopes of 3%and less, 12 to 15 feet for slopes greater than 3% but less than 10%, and
15 to 30 feet for slopes greater than 10% and less than 35%.
Seasonal High Water Table (SHWT)
There is no separation from the SHWT for overland flow. However, the elevation of the
vegetated area must be at or above the elevation of the SHWT in order for effective infiltration
to occur.
Soil Evaluation
No soil evaluation is required for overland flow on relatively permeable soils (HSGs A and B),
provided the soils have not been compacted.
For less permeable soils (HSGs C and D), or where soils have been compacted and/or where fill
has been provided, a qualified professional must evaluate the soils to determine if the soils
need to be amended to compensate for poor infiltration capability.

Soil Amendments
Soils may be amended where they are not suitable for infiltration or where minimum distances
and/or slopes cannot be achieved. However, in a Runway Safety Area!RSA), where soils must
be compacted to ensure safety (FAA Specification P-152, FAA 2009), soil amendments may only
be utilized in the uppermost four inches of the soil.
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 space near the surface. Soil amendments are 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.
BMPs that Promote Standing Water
1) When DWQ receives an application that has a pond or other BMP that promotes
standing water within 5 miles of the airport, DWQ will notify the applicant of the session
law and provide a one/two page fact sheet (and copy the airport). In the notification
DWQ will encourage the applicant to meet with the airport to discuss the project to
answer any questions and address any concerns the airport may have in light of 5229.
2) If additional information is required, DWQ will send an "Additional Information" letter
(and copy the airport). Again DWQ will include the one/two page fact sheet, and if the
applicant has not done so already, DWQ will again encourage the applicant to meet with
the airport to discuss the project to answer any questions and address any concerns the
airport may have in light of S229.
3) When DWQ issues the permit, DWQ will copy the airport. The cover letter will include
the following language... "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, P.O.
Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this permit
shall be final and binding."
