Dear Mr. Barrett:
The Wilmington Regional Office received a revised Stormwater Submittal for the Albert Ellis
Airport on January 11, 1995, with fmal information on January 17, 1995. Staff review of the plans and
specifications, including the statement of intent to deed restrict the allowable built-upon area to 12.1 acres
for the tract as shown on the approved plan, has determined that the project as proposed will comply with
the Stormwater Regulations set forth in Title 15A NCAC 2H.1003(a)(3).
Any modification of the plans submitted to and approved by this Office or further development of
this site regardless of the fact that the modification may be less than 1 acre, will require an additional
Stormwater Submittal/Modification and approval prior to initiation of construction. Modifications include
but are not limited to; project name changes, transfer of ownership, redesign of built-upon surfaces,
addition of built-upon surfaces, redesign or further subdivision of the project area as shown on the
approved plans.
This Certification shall be effective from the date of issuance until rescinded. The project shall be
constructed and maintained in accordance with the plans and specifications approved by the Wilmington
Regional Office. This Certification supersedes the one issued to you on October 6, 1993. The developer
is responsible for obtaining any and all permits and approvals necessary for the development of this
project. This could include the Division of Coastal Management under CAMA requirements, the Division
of Environmental Management under Wetland 401 Water Quality Certification and/or a Dredge and Fill
Permit and/or a Sewer Extension/Collection Permit, U.S. Army Corps of Engineers 404 Wetland Permit,
NPDES stormwater permit if disturbing five acres or more, local County or Town Agency permits under

CONSTRUCTION METHODS
11
893-3 . 1 FENCE INSTALLATION. The Contractor shall install
temporary silt fences as shown on the drawings and at other
locations as directed by the Engineer. Fence construction shall beI/
adequate to handle the stress from sediment loading. Geotextile
shall be adequately fastened to the support fence. Geotextile at
the bottom of the fence shall be buried a minimum of 6 inches in a
trench so that no flow can pass under the barrier. The trench
shall be backfilled and the soil compacted over the geotextile.
Fence height shall be not less than 32 inches or more than 36
inches above ground surface. The geotextile shall be spliced 11
together only at a support post, with a minimum 6-inch overlay.
893-3 .2 POSTS. Posts shall be' spaced a maximum of 8 feet apart I
and where possible placed or driven a minimum of 24 inches into the
ground. Where a 24 inch depth is impractical to achieve, the posts
shall be adequately secured to prevent overturning of the fence due
to sediment loading.
893-3 . 3 WIRE SUPPORT. When wire support fence is used, the wire.
mesh shall be fastened securely to the up slope side of the post.
The wire shall extend into the trench a minimum of two inches and
extend a maximum of 36 inches above the original ground surface.
893 . 3 .4 SELF SUPPORT_ When self supported fence is used, the
geotextile shall be securely fastened to fence posts.
893-3 .5 RESPONSIBILITY. It is the Contractor's responsibility to
maintain the integrity of silt fences as long as they are necessary
to contain sediment runoff. The Contractor shall inspect all
temporary silt fences immediately after each rainfall and at least
daily during prolonged rainfall. Any deficiencies shall be
immediately corrected by the Contractor. In addition, the
Contractor shall make a daily review of the location of silt fences11
E-893-2
I
in areas where construction activities have changed the natural
contour and drainage runoff to ensure that the silt fences are
properly located for effectiveness. Where deficiencies exist,
additional silt fences shall be installed as directed by the
Engineer. Should the silt fence become damaged, clogged, or
otherwise ineffective while the barrier is still necessary, it
shall be repaired or replaced promptly by the Contractor at his
expense.
893-3 . 6 SEDIMENT. Sediment deposits shall be removed when the
deposit reaches approximately one-half of the height of the silt
fence.
893-3 .7 REMOVAL. The silt fence shall remain in place until the
Engineer directs that it be removed. Upon removal, the Contractor
shall remove and dispose of any excess sediment accumulations,
dress the area to give a pleasing appearance, and vegetate all bare
areas in accordance with the contract requirements. The fence
materials will remain the property of the Contractor and may be
used at other locations provided the materials meet the
requirements in Table 1.
METHOD OF MEASUREMENT
893-4 . 1 The quantity of temporary silt fence to be paid for will
be the actual ;umber of linear feet of silt fence, measured in
place from end post to end post of each separate installation,
which has been completed and accepted.
BASIS OF PAYMENT
893-5. 1 No separate payment will be made for removal and disposal
of sediment accumulations. The cost of this work shall be
considered incidental to the cost of temporary silt fence.
893-5. 2 Payment for accepted temporary silt fence shall be made at
the contract unit price per linear foot.
The above price shall be full compensation for all work covered by
this item, including but not limited to furnishing all fence posts,
fence fabric, filter fabric, hardware, and other material;
installing and maintaining the silt fence; removal and disposal of
sediment accumulations from the silt fence; removal of the silt
fence; and dressing the disturbed areas after the silt fence has
been removed.

901-2 .4 SOIL FOR REPAIRS. The soil for fill and topsoiling of areas to
be repaired shall be at least of equal quality to that which exists in
areas adjacent to the area to be repaired. The soil shall be relatively
free from large stones, roots, stumps, or other materials that will
interfere with subsequent sowing of seed, compacting, and establishing
turf, and shall be approved by the Engineer before being placed.
Construction Methods
901-3. 1 ADVANCE PREPARATION AND CLEANUP. After grading of areas has
been completed and before applying fertilizer and ground limestone,
areas to be seeded shall be raked or otherwise cleared of stones larger
than 2 inches (50 mm) in any diameter, sticks, stumps, and other debris
which might interfere with sowing of seed, growth of grasses, or
subsequent maintenance of grass-covered areas. If any damage by erosion
or other causes has occurred after the completion of grading and before
beginning the application of fertilizer and ground limestone, the
Contractor shall repair such damage. This may include filling gullies,
smoothing irregularities, and repairing other incidental damage.
An area to be seeded shall be considered a satisfactory seedbed without
additional treatment if it has recently been thoroughly loosened and
worked to a depth of not less than 5 inches (125 mm) as a result of
grading operations and, if immediately prior to seeding, the top 3
inches (75 mm) of soil is loose, friable, reasonably free from large
clods, rocks, large roots, or other undesirable matter, and if shaped to
the required grade.
However, when the area to be seeded is sparsely sodded, weedy, barren I
and unworked, or packed and hard, any grass and weeds shall first be cut
or otherwise satisfactorily disposed of, and the soil then scarified or
otherwise loosened to a depth not less than 5 inches (125 nun) . Clods
shall be broken and the top 3 inches (75 mm) of soil shall be worked
T-901-2
I
into a satisfactory seedbed by discing, or by use of cultipackers,
rollers, drags, harrows, or other appropriate means.
901-3.2 DRY APPLICATION METHOD.
a. Liming. Lime shall be applied separately and prior to the
application of any fertilizer or seed and only on seedbeds which have
previously been prepared as described above. The lime shall then be
worked into the top 3 inches (75 mm) of soil after which the seedbed
shall again be properly graded and dressed to a smooth finish.
b. Fertilizing. Following advance preparations and cleanup
fertilizer shall be uniformly spread at the rate which will provide not
1 less than the minimum quantity stated in paragraph 901-2. 3.
..I c. Seeding. Grass seed shall be sown at the rate specified in
paragraph 901-2. 1 immediately after fertilizing, and the fertilizer and
seed shall be raked within the depth range stated in the special
provisions. Seeds of legumes, either alone or in mixtures, shall be
inoculated before mixing or sowing, in accordance with the instructions
of the manufacturer of the inoculant. When seeding is required at other
than the seasons shown on the plans or in the special provisions, a
cover crop shall be sown by the same methods required for grass and
legume seeding.
d. Rolling. After the seed has been properly covered, the seedbed
shall be immediately compacted by means of an approved lawnroller,
weighing 40 to 65 pounds per foot (60 to 97 kg per meter) of width for
clay soil (or any soil having a tendency to pack) , and weighing 150 to
200 pounds per foot (223 to 298 kg per meter) of width for sandy or
light soils.
901-3.3, WET APPLICATION METHOD.
a. General. The Contractor may elect to apply seed and fertilizer
(and lime, if required) by spraying them on the previously prepared
seedbed in the form of an aqueous mixture and by using the methods and
equipment described herein. The rates of application shall be as
specified in the special provisions.
b. Spraying Equipment. The spraying equipment shall have a
container or water tank equipped with a liquid level gauge calibrated to
read in increments not larger than 50 gallons (190 liters) over the
entire range of the tank capacity, mounted so as to be visible to the
nozzle operator. The container or tank shall also be equipped with a
mechanical power-driven agitator capable of keeping all the solids in
the mixture in complete suspension at all times until used.
The unit shall also be equipped with a pressure pump capable of
delivering 100 gallons (380 liters) per minute at a pressure of 100
pounds per square inch (690 kPa) . The pump shall be mounted in a line
which will recirculate the mixture through the tank whenever it is not
11 T-901-3
I
i
being sprayed from the nozzle. All pump passages and pipe lines shall
be capable of providing clearance for 5/8 inch (15 mm) solids. The
power unit for the pump and agitator shall have controls mounted so as
to be accessible to the nozzle operator. There shall be an indicating
pressure gauge connected and mounted immediately at the back of the
nozzle.
The nozzle pipe shall be mounted on an elevated supporting stand in such
a manner that it can be rotated through 360 degrees horizontally and
inclined vertically from at least 20 degrees below to at least 60
degrees above the horizontal. There shall be a quick-acting, three-way
control valve connecting the recirculating line to the nozzle pipe and
mounted so that the nozzle operator can control and regulate the amount
of flow of mixture delivered to the nozzle. At least three different
types of nozzles shall be supplied so that mixtures may be properly
sprayed over distance varying from 20 to 100 feet (6 to 30 m) . One
shall be a close-range ribbon nozzle, one a medium-range ribbon nozzle,
and one a long-range jet nozzle. For case of removal and cleaning, all
nozzles shall be connected to the nozzle pipe by means of quick-release
couplings.
In order to reach areas inaccessible to the regular equipment, an
extension hose at least 50 feet (15 m) in length shall be provided to
which the nozzles may be connected.
c. Mixtures. Lime, if required, shall be applied separately. in
the quantity specified, prior to the fertilizing and seeding
operations. Not more than 220 pounds (100 kg) of lime shall be added to
and mixed with each 100 gallons (380 liters) of water. Seed and
fertilizer shall be mixed together in the relative proportions
specified, but not more than a total of 220 pounds (100 kg) of these
combined solids shall be added to and mixed with each 100 gallons (380
liters) of water.
All water used shall be obtained from fresh water sources and shall be
free from injurious chemicals and other toxic substances harmful to
plant life. Brackish water shall not be used at any time. The
Contractor shall identify to the Engineer all sources of water at least
2 weeks prior to use. The Engineer may take samples of the water at the
source or from the tank at any time and have a laboratory test the
samples for chemical and saline content. The Contractor shall not use
any water from any source which is disapproved by the Engineer following
such tests.
All mixtures shall be constantly agitated from the time they are mixed
until they are finally applied to the seedbed. All such mixtures shall
be used within 2 hours from the time they were mixed or they shall be
wasted and disposed of at locations acceptable to the Engineer.
d: Spraying. Lime, if required, shall be sprayed only upon
previously prepared seedbeds. After the applied lime mixture has dried,
the lime shall be worked into the top 3 inches (8 cm) , after which the
T-901-4
I
I
seedbed shall again be properly graded and dressed to a smooth finish.
Mixtures of seed and fertilizer shall only be sprayed upon previously
prepared seedbeds on which the lime, if required, shall already have
been worked in. The mixtures shall be applied by means of a
high-pressure spray which shall always be directed upward into the air
so that the mixtures will fall to the ground like rain in a uniform
spray. Nozzles or sprays shall never be directed toward the ground in
such a manner as might produce erosion or runoff.
Particular care shall be exercised to insure that the application is
made uniformly and at the prescribed rate and to guard against misses
and overlapped areas. Proper predetermined quantities of the mixture in
accordance with specifications shall be used to cover specified sections
of known area. Checks on the rate and uniformity of application may be
made by observing the degree of wetting of the ground or by distributing
test sheets of paper or pans over the area at intervals and observing
the quantity of material deposited thereon.
11 On surfaces which are to be mulched as indicated by the plans or
designated by the Engineer, seed and fertilizer applied by the spray
method need not be raked into the soil or rolled. However, on surfaces
on which mulch is not to be used, the raking and rolling operations will
be required after the soil has dried.
11 901-3.4 MAINTENANCE OF SEEDED AREAS. The Contractor shall protect
seeded areas against traffic or other use by warning signs or
barricades, as approved by the Engineer. Surfaces gullied or otherwise
damaged following seeding shall be repaired by regrading and reseeding
as directed. The Contractor shall mow, water as directed, and otherwise
maintain seeded areas in a satisfactory condition until final inspection
and acceptance of the work.
11 When either the dry or wet application method outlined above is used for
work done out of season, it will be required that the Contractor
establish a good stand of grass of uniform color and density to the
satisfaction of the Engineer. If at the time when the contract has been
otherwise completed it is not possible to make an adequate determination
of the color, density, and uniformity of such stand of grass, payment
for the unaccepted portions of the areas seeded out of season will be
withheld until such time as these requirements have been met.

ITEM T-908 MULCHING
Description
908-1. 1 This item shall consist of furnishing, hauling, placing, and
securing mulch on surfaces indicated on the plans or designated by the
Engineer.
Materials
908-2 . 1 MULCH MATERIAL. Acceptable mulch shall be the materials listed
below or any approved locally available material that is similar to
those specified. Low grade, musty, spoiled, partially rotted hay,
straw, or other materials unfit for animal consumption will be
acceptable. Mulch materials, which contain matured seed of species
which would volunteer and be detrimental to the proposed overseeding, or
to surrounding farm land, will not be acceptable. Straw or other mulch
material which is fresh and/or excessively brittle, or which is in such
an advanced stage of decomposition as to smother or retard the planted
grass, will not be acceptable.
a. Straw. Straw shall be the threshed plant residue of oats,
wheat, barley, rye, or rice from which grain has been removed.
1 b. Asphalt Binder. Asphalt binder material shall conform to the
requirements of ASTM D 977, Type SS-1 or RS-1.
908-2 .2 INSPECTION. Within 5 days after acceptance of the bid, the
Engineer shall be notified of sources and quantities of mulch materials
available and the Contractor shall furnish him with representative
samples of the materials to be used. These samples may be used as
standards with the approval of the Engineer and any materials brought on
the site which do not meet these standards shall be rejected.
Construction Methods
908-3 . 1 MULCHING. Before spreading mulch, all large clods, stumps,
stones, brush, roots, and other foreign material shall be removed from
the area to be mulched. Mulch shall be applied immediately after
seeding. The spreading of the mulch may be by hand methods, blower, or
other mechanical methods, provided a uniform covering is obtained.
Mulch material shall be furnished, hauled, and evenly applied on the
area shown on the plans or designated by the Engineer. Straw or hay
shall be spread over the surface to a uniform thickness at the rate of
2 to 3 tons per acre (1800-2700 kg per acre) to provide a loose depth of
not less than 1-1/2 inches (37 cm) nor more than 3 inches (75 mm) .
Other organic material shall be spread at the rate directed by the
Engineer. Mulch may be blown on the slopes and the use of cutters in
the equipment for this purpose will be permitted to the extent that at
least 95% of the mulch in place on the slope shall be 6 inches (150 mm)
or more in length. When mulches applied by the blowing method are cut,
T-908-1
I
the loose depth in place shall be not less than 1 inch (25 mm) nor more
than 2 inches (50 mm) .
908-3 .2 SECURING MULCH. The mulch shall be held in place by light
discing, a very thin covering of topsoil, small brush; pins, stakes,
wire mesh, asphalt binder, or other adhesive material approved by the
Engineer. Where mulches have been secured by either of the asphalt
binder methods, it will not be permissible to walk on the slopes after
the binder has been applied. The Contractor is warned that in the
application of asphalt binder material he must take every precaution to
guard against damaging or disfiguring structures or property on or
adjacent to the areas worked and that he will be held responsible for
any such damage resulting from his/her operations.
If the "peg and string" method is used, the mulch shall be secured by
the use of stakes or wire pins driven into the ground on 5-foot (150 m)
centers or less. Binder twine shall be strung between adjacent stakes
in straight lines and crisscrossed diagonally over the mulch, after
which the stakes shall be firmly driven nearly flush to the ground to
draw the twine down tight onto the mulch.
908-3 .3 CARE AND REPAIR.
a. The Contractor shall care for the mulched areas until final
acceptance of the project. Such care shall consist of providing
protection against traffic or other use by placing warning signs, as
approved by the Engineer, and erecting any barricades that may be shown
on the plans before or immediately after mulching has been completed on
the designated areas.
b. The Contractor shall be required to repair or replace any
mulching that is defective or becomes damaged until the project is
finally accepted. When, in the judgment of the Engineer, such defects
or damages are the result of poor workmanship or failure to meet the
requirements of the specifications, the cost of the necessary repairs or
replacement shall be borne by the Contractor. However, once the
Contractor has completed the mulching of any area in accordance with the
provisions of the specifications and to the satisfaction of the
Engineer, no additional work at his/her expense will be required, but
subsequent repairs and replacements deemed necessary by the Engineer
shall be made by the Contractor and will be paid for as additional or
extra work.
c. If the "asphalt spray" method is used, all mulched surfaces
shall be sprayed with asphalt binder material so that the surface has a
uniform appearance. The binder shall be uniformly applied to the mulch
at the rate of approximately 8 . 0 gallons (32 liters) per 1, 000 square
feet (100 square meters) , or as directed by the Engineer, with a minimum
of 6. 0 gallons (24 liters) and a maximum of 10 gallons (40 liters) per
1, 000 square feet (100 square meters) depending on the type of mulch and
the effectiveness of the binder securing it. Bituminous binder material
may be sprayed on the mulched slope areas from either the top or the
T-908-2
bottom of the slope. An approved spray nozzle shall be used. The
nozzle shall be operated at a distance of not less than 4 feet (120 cm)
from the surface of the mulch and uniform distribution of the bituminous
material shall be required. A pump or an air compressor of adequate
capacity shall be used to insure uniform distribution of the bituminous
material.
d. If the "asphalt mix" method is used, the mulch shall be
applied by blowing, and the asphalt binder material shall be sprayed
into the mulch as it leaves the blower. The binder shall be uniformly
applied to the mulch at the rate of approximately 8. 0 gallons (32
liters) per 1, 000 square feet (100 square meters) or as directed by the
Engineer, with a minimum of 6.0 gallons (24 liters) and a maximum of 10
gallons (40 liters) per 1,000 square feet (100 square meters) depending
on the type of mulch and the effectiveness of the binder securing it.
Method of Measurement
908-4. 1 Mulching shall be measured in acres on the basis of the actual
surface area acceptably mulched.
Basis of Payment
908-5. 1 Payment win be made at the contract unit price per acre for
mulching. The price shall be full compensation for furnishing all
materials and for placing and anchoring the materials, and for all
labor, equipment, tools, and incidentals necessary to complete the item.
