Scott,
I appreciate you and the Division of Land Resources office (Pat) help in completing this task. I am meeting today with a
consultant from Wilmington to discuss Storm water methodologies with the City of Elizabeth City and the Regional
airport (FBO) that actually owns the land our two hangars resides on. I am confident that the previous management had
the best of intentions for this requirement, however a plethora of loose ends has me concerned.
cc'd the signature engineer (Sean Robey) on this communication.
I would like to report that I "will not" be inspecting any sediment layers in the retention ponds this week as they are
covered in ICE. It's not even WINTER yet.
Merry Christmas all.

Scott,
Trust your getting ready for Santa?
We were talking a month ago or so about : "how do I close out this Sediment and Control Plan that was issued to the old
company name (TAMSCO) July 2007. It was issued for the duration of the construction of our second hangar, yet never
closed out. I had some corporate folks here last week and they said, as well, close it out. How should I proceed. I believe
a representative from your office or Division of Land Management will need to come for a final?
I also wanted to know if the request of name change, on SW7070706, had been received and was the documentation
satisfactory?

I write this letter in support of DRS C3 & Aviation Company's request to transfer the
referenced Storm Water Permit to our legal name.
I enclose a copy of a Certificate of Incorporation dated 03 April 2009. I also enclose a
copy of an email from our corporate legal office. TAMSCO Corporation does not exist in
any farm as of April 2009. TAMSCO began this project in July of 2007 as Phase 2 of a
construction project that required wet retention ponds in accordance with 15A NCAC
2H.1000 (stonn water rules).
Mr. Jeff Berry ( TAMSCO) is no longer affiliated with this new company and therefore is
not available to sign as the transferee. Also, I retain a copy of the site plan signed by Mr.
Sean C.Robey P.E., of Hyman & Robey (NC seal 18550).
I thank you for your time and effort on this behalf and will remain readily available for
any additional questions that might arise with this request.

In pursuit of my EH&S duties, I continue to find local, state and Federal requirement documents/permits that are still
listed with external agencies as "TAMSCO Corporation". Concerning name changes and organizational codes has the
company formally named TAMSCO dissolved or is it still a representing body within our organization. I need to execute

-2-

of directors that shall constitute the whole Board of Directors shall be fixed by, or in the manner
provided in the by-laws. The phrase "whole Board" and the phrase "total number of directors"
shall be deemed to have the same meaning, to wit, as the total number of directors that this
Corporation would have if there were no vacancies. No election of directors need be by written
ballot.
2. Voting -of Stock. Each outstanding share shall entitle the holder
thereof to notice of, and the right to one (1) vote at, any meeting of stockholders.
ELEVENTH: 1. Right to Indemnification. Each person who was or is made a
party or is threatened to be made a party to or is involved in any action, suit or proceeding,
whether civil, criminal, administrative or investigative (hereinafter called a "proceeding") by
reason of the fact that he or she, or a person of whom he or she is the legal representative, is or
was a director or officer of this Corporation or while serving as a director or officer, is or was
serving at the request of this Corporation as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, shall be indemnified and held harmless by this Corporation to
the fullest extent authorized by the General Corporation Law of the State of Delaware, as the
same exists or may hereafter be amended (but, in the case of any such amendment, the rights of
indemnification provided hereby shall continue as theretofore notwithstanding such amendment
unless such amendment permits this Corporation to provide broader indemnification rights than
said law permitted this Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in
connection therewith and such indemnification shall continue as to a person who has ceased to
be director or officer, and shall inure to the benefit of his or her heirs, executors, administrators
and personal representatives; provided, however, that, except as provided in paragraph 2 hereof,
this Corporation shall indemnify any such person seeking indemnification in connection with a
proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of this Corporation.
The right to indemnification conferred in this section shall be a contract right and
shall include the right to be paid by this Corporation the expenses incurred in defending any such
proceeding in advance of its final disposition; provided, however, that, if the General
Corporation Law of the State of Delaware requires, the payment of such expenses incurred by a
director or officer in his or her capacity as a director or officer (and not in any other capacity in
which service was or is rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final disposition of a
proceeding, shall be made only upon delivery to this Corporation of an undertaking, by or on
behalf of such director or officer, to repay all amounts so advanced if it shall be ultimately
determined that such director or officer is not entitled to be indemnified under this section or
otherwise. This Corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of this Corporation with the same scope and effect as the foregoing
indemnification of directors and officers.
-3-

2. Right of Claimant to Bring Suit. A claimant may bring suit against this
Corporation under paragraph 1 of this Article ELEVENTH only if this Corporation fails to pay
in full within thirty (30) days of its receipt of a written claim for payment hereunder. If
successful in whole or in part, the claimant shall be entitled to be paid also the expense of
prosecuting such claim (including, but not limited to, attorneys' fees). It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required undertaking, if
any is required, has been tendered to this Corporation) that the claimant has not met the
standards of conduct that make it permissible under the General Corporation Law of the State of
Delaware for this Corporation to indemnify the claimant for the amount claimed, but the burden
of proving such defense shall be on this Corporation. Neither the failure of this Corporation
(including its Board of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of the claimant is
proper in the circumstances because he or she has met the applicable standard of conduct, set
forth in the General Corporation Law of the State of Delaware, nor an actual determination by
this Corporation (including its Board of Directors, independent legal counsel, or its stockholders)
that the claimant has not met such applicable standard of conduct, shall be a defense to the action
or create a presumption that the claimant has not met the applicable standard of conduct.
3. Non -Exclusivity of Rights. The right to indemnification and the payment
of expenses incurred in defending a proceeding in advance of its final disposition conferred in
this Article ELEVENTH shall not be exclusive of any other right that any person may have or
hereafter acquire under any statute, provision of the Certificate of Incorporation, by-law,
agreement, vote of stockholders or disinterested directors or otherwise.
4. Insurance. This Corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of this Corporation or another
corporation, partnership, joint venture, trust or other enterprise against any such expense, liability
or loss, whether or not this Corporation would have power to indemnify such person against such
expense, liability or loss under the General Corporation Law of the State of Delaware.
IN WITNESS WHEREOF, this Certificate of Incorporation has been signed this
3rd day of Apri12009.

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST

Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 4.5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2.2 5 feet in the forebay, the sediment shall be removed.

Re: Fountains in Stormwater Extended Wet Detention Ponds
After doing some research and consulting with Bill Hunt of NCSU, I am ready to make the following recommendation in
regards to allowing the use of decorative fountains in stormwater ponds. I am basing my recommendations on the fact
that certain benefits may be realized by the addition of such devices. First, surface disturbance of the pond can increase
dissolved oxygen levels in the pond and enhance biological activity that can be beneficial in removing some pollutants of
concern. Second, gentle mixing of the water column may aid in flocculation of certain pollutants as well as allow for
contact with the anoxic zone of the pond's bottom encouraging de -nitrification. Third, disturbing the surface of the pond
can discourage mosquito breeding.
After researching different products designed for use in ponds, I discovered a variety of aeration and fountain type
systems. I do not recommend the use of the aeration systems that work like fish tank bubble stone as they would create
too much disturbance. I do recommend surface fountains that draw water from less than 2 feet. Some of the surface
fountains simply float on top of the water and have the intake, pump and fountain nozzle all in one unit. These dearly
draw water at the surface. Others make use of a separated nozzle, pump, and/or intake connected by tubing. If these are
to be used they must draw their water from the surface in the deepest part of the pond. Also, I recommend that the falling
water from the fountain be centered in the pond and away from the shore line.
In regards to sizing the pump, it seemed appropriate to compare the energy input to the pond volume using a velocity
gradient that would encourage flocculation in water treatment applications. The assumption is that if small enough amount
of energy input was used that re -suspension would not be an issue. Further, if the amount of energy added by the
fountain was comparable to that needed to encourage flocculation of fecal coliform, for instance, then it may even prove to
be a benefit. As a Final check, I also determined the detention time based on pumping rates to further show that too much
mixing would not occur. The shortest detention times were in the order of two days.
Based on the above, here is the proposed schedule of maximum pump power (hp) vs. minimum pond volume (cubic feet).

DRS Technologies is an aircraft repair facility that failed to receive a storm water
management permit during construction of the existing building. Now the facility is
planning to expand on its 12 acre site located at the Elizabeth City — Pasquotank County
Regional Airport. The site is located on the west side of Consolidated Road — SR 1131 in
Pasquotank County. This permit application will provide storm water treatment for the
existing building and parking as well as all new improvements, with exceptions as noted.
The submitted plans show the existing facility and the proposed expansion. We have
divided the site into two drainage areas. Area 1 will contain half of the existing building,
most of the existing parking areas, the approach slab located behind the existing building,
and a small part of the taxiway. Previous runoff from the air field will be redirected so
that it will no longer drains through Area 1. Area 2 will contain the proposed
construction and half of the existing building. The proposed expansion will involve the
demolition of the parking lot to the west of the existing building to allow the addition of a
10,000 SF hangar and another 80,000 SF aircraft hangar. The approach apron behind the
proposed expansion is previously permitted by others.
According to the Pasquotank County Soils Maps as prepared by USDA, Soil
Conservation Service, the soils on this site are Roanoke. Two soil borings were
performed in the area of the detention pond by Sean C. Robey, PE and Kimberly Hamby
on May 21, 2007. All soil borings were conducted with and AMS 2-314" diameter 6'
long hand mud auger. Boring 1 was located in an area where underground tanks were
previously located. The only soil present was sand fill. The elevation at that location is
approximately 8.5'. The color of the sand began to change between 48-54" and there was
obvious wetness at 60". Boring 2 was located in native soil slightly outside of the limits
of the detention pond. The elevation at this location is approximately 8.0'. The first 4-6"
was topsoil. From 6-48" was clay, from 48-60" was a silty clay, and at 60" we
encountered wet, light colored sand. The clay is typical for Roanoke soils. Based upon
these two borings, we estimate the water table to be between elevation 3.0 and 3.5.
Permanent pool elevation for the detention pond has been set at elevation 3.5.
Drainage Area 1 contains 6.06 acres and includes the eastern half of the existing 80,000 sf
aircraft hangar with related parking, drive aisles, sidewalk and concrete aircraft approach
slab areas. The approach slab located behind the existing DRS Technologies hangar
contains drop inlets originally designed to capture all of the runoff from the slab. During
construction, the slab was re -graded to sheet flow to two grassed areas located between

In
the access drives. Due to the re -grading of the slab, little if any water actually drains to
the drop inlets. The grassed areas between the apron and the taxiway are currently
drained by drop inlets that route the storm water to the Consolidated Road roadside ditch.
The parking in front of the existing hangar also drains to the roadside ditch via
stormwater flumes. Future master planning of the Elizabeth City — Pasquotank County
Aviation Center located directly across Consolidated Road will provide for stormwater
treatment for Area 1. The Aviation Center Master Plan is currently underway and we
expect stormwater permit application for the Aviation Center to be ready for submittal
within 6 months. To provide immediate interim treatment for the runoff from these areas,
drain guards will be installed in each of the existing drop inlets and curb flumes.
Specifications for these devices are included in the details sections of the plans.
Drainage Area 2 contains 4.24 acres and represents the amount of new impervious
drainage area added by the construction of the new hanger facility. All of the storm water
generated by the new hangar facility will be treated by the wet detention pond located to
the west of the site. Drainage from the west side of the existing building, (40,000 sf) is
currently handled in underground gutter collection system. This collection system drains
to the roadside ditch untreated. During the construction of the expansion, this water will
be intercepted and re -directed to the new wet detention pond on the west side of the
property. The direct outfall to the roadside ditch will be plugged. The existing parking
lot and 10,000 sf hanger will be absorbed into the new construction. The water from this
area is also directed to the western wet pond. The detention basin is designed for storage
of 1" of runoff and 90% TSS removal. The pond cannot be increased in size due being
constrained by existing gravity sewer along Consolidated Road, drainage re-routing
against the existing apron and the sewer pump station.
The total disturbed area for this project will not exceed S acres. Limits of disturbance
have been shown on the plans.
As mentioned in the soils reporting section of this report, there were fuel tanks removed
from the area proposed for the detention pond. Contamination was found and a previous
effort was made to remove and replace the contaminated soil. Upon the last
environmental inspection, some contamination was still evident. Please see the attached
letter from NCDENR, Division of Waste Management, Underground Storage Tank
Section. We expect that any remaining contamination will be removed during the
construction of the detention pond. All material excavated for the purposed of
constructing the pond will be handled as if it is contaminated.

Scott and Lyn,
Following is the additional information you requested for the TAMSCO Storm Water permit. The checks were
erroneously sent directly to you for this project and it is our understanding that Lyn is holding them. We would
also like to clarify an error on the plans. The disturbed area as shown on the plans is correct. However, in the site
data it is incorrect. The disturbed area is 4.58 acres not 3.96 acres. The check which was sent to youfor the
Erosion and Sediment Control permit was for 5 acres ($250.00) which is correct. If you have any questions,
please do not hesitate to call me at 335-1888.
Thank you,
Angela
