B. Project Description
Attachment 2 of the study contains a Preliminary Engineering Report(PER),
which was prepared in March of 1999. This study outlines the need for the
project, its sizing,location,and treatment process. In the PER,the treatment
process outline utilized conventional treatment consisting of pressure
filtration and ion exchange softening. Backwash water from the pressure
filters and the brine backwash from the softeners were to be discharged into
the Scuppernong River.
As the project proceeded, the Owners and Engineers began to realize the
problems associated with the shallow aquifers in the region and utilization of

• conventional treatment in these shallow aquifers. Conventional treatment
was adequate for the shallow aquifers; however, there are major problems
with ample supply of water from these aquifers as well as a change in water
quality over a period of time primarily due to an upconing of chlorides from
the lower aquifers. It was determined that reverse osmosis treatment would
be best suited for this northeastern county with utilization of the deeper
aquifers where was sufficient quantity to meet future demands. The reverse
osmosis treatment will meet the long term changing regulations as well as be
able to treat the higher chlorides in the low aquifers. Attachment 3 to this
report contains an updated scope of the project.
As a result of the change in treatment process from conventional to reverse
osmosis, discussions were held with the Division of Water Quality to
discharge into the Scuppernong River. As a result of discussions, it was
determined it would be feasible to locate the discharge in the Albemarle
Sound in lieu of the Scuppernong River. Attachment 4 contains a location
map of the proposed discharge into the Albemarle Sound. Attachment 5
contains a letter from the Division of Water Quality indicating the feasibility
of discharge into the Albemarle Sound.
The PER in Attachment 2 illustrates the flow calculations for the water
treatment plant. It is anticipated that the RO plant will have a 25%
concentrate discharge; therefore, based on a supply of 400 gallons per
minute, 300 gallons per minute will be potable minute and 100 gallons per
minute will be discharged into the Albemarle Sound.
C. Existing Facilities
Existing facilities will not be a part of this project.
D. Project Phasing
The initial phase of the project will be a 300-gallon per minute RO plant. The
pipeline and building will be sized to allow future expansion of the treatment
process. The components of the facility will be sized to allow a future RO train to be
added to increase capacity from 300 gallons per minute to 600 gallons per minute. If
the building is properly sized, the addition of a RO train will be an easy addition in
the future.
It is not foreseeable that the growth of the County will require expansion of the plant
in the near future. It is more expected that the schedule for expansion of the
proposed plant will be dependent upon the life expectancy of the existing water
treatment plant located south of Columbia on N.C. Highway 94. The existing plant
is approximately 30 years old and is in need of major repairs and renovations. In
addition, the quality of the groundwater in the wells is deteriorating rapidly due to

intrusion of chlorides as well as a loss in flow capacity. Due to a lack of a discharge
in the area of the existing plant,reverse osmosis is not an alternative at this location.
With expansion of the proposed RO plant from 300 gallons per minute to 600
gallons per minute,the discharge would proportionally increase from 100 gallons per
minute to 200 gallons per minute or 144,000 gallons per day to 288,000 gallons per
day.
II. EVALUATE DISPOSAL ALTERNATIVES
A. Connecting to a Sewer Collection System
The nearest publicly or privately owned sewage treatment facility is located in the
Town of Creswell. This facility is approximately 7 miles from the proposed Tyrrell
County RO plant. The Town of Creswell's sewer facility is a lagoon system.
The distance to this sewage treatment facility will be much more expensive than a
discharge to the Albemarle Sound and is outside of the 5 mile radius of consideration
for the EAA. It is also pointed out that the chloride concentrations of reverse
osmosis treatment plant discharges are too high to be processed in any type of
biological sewage treatment facility. The RO discharge would quickly upset the
treatment process and render the facility useless.
In addition, there are no plans for future sewage treatment facilities within a 5-mile
radius within 5 years,public or private,in the area.
B. Land Based Disposal
Land application is not a feasible alternative for the disposal of RO concentrate.
Chloride levels in the RO co,ncentrate would quickly kill plant life on land surfaces
including trees and grasses. Concentrate discharge from the RO plant is expected to
in the range of 6,000 ppm of chlorides)Typical land based plant life can withstand
chloride levels up to approximatley 1,100 ppm of chlorides.
There is an insufficient amount of suitable land in the area to land apply RO
concentrate. In addition, the cost for installation would be very high. As an
example, assuming a loading rate of 0.4 gallons per day/square foot would require
23 miles of drain lines or approximately 50 acres of land for the initial phase of the
RO plant.
C. Wastewater Reuse
Due to the chloride concentrations of the wastewater, wastewater reuse is not an
option for options such as land application.

• D. Surface Water Discharge
1. The Albemarle Sound does not have an associated 7Q10 or 30Q2 flow.
2. Tertiary filtration on reverse osmosis concentrate will not provide quality
improvements.
3. Attachment 6 to this report contains plans and specifications of the discharge
piping for the project.
4. Land Easement Agreements
Attachment 7 contains information available to date on the land and
easements necessary to construct the discharge pipe.
5. Present Value of Cost Analysis
Attachment 8 to this report contains the present value of cost analysis for the
discharge pipe.
E. Disposal Combinations
The proposed discharge of the RO concentrate into the Albemarle Sound is the only
feasible alternative for the project.

• I. General
Tyrrell County built a county water system in the mid 1970's primarily through a grant
from the USDA-Farmer's Home Administration Program. Since then,the system has
expanded through various Department of Commerce—Community Development Block
Grant programs. The system consists of approximately 115 miles of 8-inch and smaller
. water mains. Water is supplied by two wells and a conventional pressure
filtration/softening water plant.
There are approximately 1,121 residential users and 10 commercial users. The County is
very rural and the commercial users are primarily farmers.
The northwest corner of the County is isolated by the Scuppernong River. An 8-inch
subaqueous water main crossing this river in one location provides all the water to this
region. There are approximately 400 users in this section of the.county which would be
out of water if the water main crossing were ever to fail.
The water treatment facilities are nearing its rated capacity. An additional water source is
needed to meet the demands of the system as well as provide a water source in the
northwest corner of the County should the Scuppernong River water main crossing ever
fail. The State of North Carolina is building a 4-H Center in this section of the County.
Funds have been allocated with the 4-H Center to construct a 200,000 gallon elevated
storage tank. The County does not have the means to fill this tank at the present time.
A new water plant is needed to fill the new water tank,meet the needs to the northeast
section of the County and supplement the water source for the remaining areas of the
County.
II. Project Planning Area
A. Location
Tyrrell County is located in northeast North Carolina. Columbia is the
county seat and the only incorporated town in the county. Highways 64 and 94 bisect the
County.
The existing water treatment plant is located on Highway 94 approximately four miles
south of Columbia. An 8-inch water main extends from the water treatment plant and
crosses the Scuppernong River to serve the northwest portion of the County.
The target area is the northwest corner of the County. There are approximately 400 users
in this area. There are also plans to construct a 4-H center and 200,000 gallon elevated
storage tank in the Bull Bay area. The purpose of this project is to build a new water •
treatment facility and water source in the northwest portion of the County. The proposed
water facility will serve to provide additional water for the existing facility which is near
capacity,provide water for the northwest portion of the County should the 8-inch water
•1

• main that crosses the Scuppernong River ever need repairs and serve the proposed 4-H
Center and 200,000 gallon elevated storage tank.
•
B. Resources Present
Water resources in the area consist of surface water and ground water.
Surface waters in the area would be difficult to treat. The waters are brackish with
. seasonal fluctuations in chlorides and are high in tannins as well as color and organics.
Water sources in the area are typically ground water. Wells in the area are typically
installed in the 100-150 foot range. Ground water in the area is characterized by high
levels of iron and calcium hardness.
III. Existing Facilities
The Tyrrell County water system was built in 1976 with funds from USDA-Farmer's
Home Administration. Since then, small sections of the County have been expanded
through the Department of Commerce Community Development Block Grant programs.
The County is very rural with large users consisting primarily of farmers. The largest
user is a newly constructed prison in the northern portion of the County.
The water distribution system consists of approximately 115 miles of 8-inch and smaller
water mains. Presently there are three existing elevated water storage tanks located
primarily in the northern portion of the County.
Tyrrell County presently has two wells and one water treatment plant to serve the entire
county water system. Water production facilities consist of two wells located adjacent to
the water treatment plant. The wells are rated at 280 gallons/minute and 283
gallons/minute for a twelve-hour safe yield of 405,000 gallons/day. The water treatment
plant consists of iron removal,pressure sand filters and hardness removal ion exchange
softeners. The water treatment facility is rated at approximately 500,000 gallons/day. A
finished water booster pump station delivers water to the three elevated water storage
tanks. The finished water booster pump station is rated at approximately 400,000
gallons/day. The facilities are approximately 25 years old. In the summer of 1998, One
of the wells had to be abandoned forcing the County to apply for emergency funds
through the Drinking Water State Revolving Loan state revolving funds.
Section IV. Need
Tyrrell County presently has approximately 1,121 residential users with an additional ten
commercial users and one industrial user. Water records for 1998 indicate an average
daily usage of 200,000 gallons per day. The average of the maximum day usage for each
month is 350,000 gallons per day. At a capacity of approximately 400,000 gallons per
day, the existing water treatment facilities are approximately 88%of the rated capacity.
Spikes in water usage have been as high as 600,000 gallons per day. Appendix A
contains 1998 water records.
•2

The industrial user is a recently constructed prison. The prison presently has
approximately 250 prisoners and has an average water usage of approximately 18,400
gallons per day. The capacity is 650 prisoners with a projected usage of 65,000 gallons
per day. The prison has 164 employees and is expected to increase to 172 employees.
The State proposes to construct a new 4-H Center in Tyrrell County. Anticipated water
usage is 45,000 gallons per month putting water production and pumping facilities near
their total capacity.
. Population projections for Tyrrell County are as follows:
Year Population
1997 2,517
2000 2,700
" 2010 3,150
2020 3,600
This table represents a 30%increase in population over the next twenty years. At a
present maximum day water usage of 350,000 gallons per day, anticipated water use is as
high as 455,000 gallons per day. The prison is expected to utilize an additional 46,600
gallons per day and the 4-H Center will utilize an additional 1,500 gallons per day. Total
expected water use for the year 2020 is 503,100 gallons per day.
An additional water facility is needed to meet the future water demands of the County. In
addition, an additional water treatment facility is needed in the northwest corner of the
County should the 8-inch water main crossing the Scuppernong River presently serving
this portion of the County need repairs or become damaged.
V. Alternatives Considered
A. Do Nothing
Due to expected water demands in the future, this is not a viable
alternative for the County. With the widening of Highway 64,the northern section of the
County should experience water demand growth. In addition, should the water main
across the Scuppernong River ever break, approximately 400 users would be without
water for numerous days.
B. Expansion of Existing Facilities with Intermediate Pumping Facilities to •
the 4-H Center Elevated Water Storage Tank
The County does not presently have the means to provide water to the new
4-H Center and proposed 200,000 gallon elevated water storage tank. One alternative is •
to install a new booster pump station to fill this tank.
3

•
Installation of an intermediate booster pump station to serve the 4-H Center tank would
involve installation of a new booster pump station and ground storage tank in the vicinity
of the Scuppernong River water main crossing,new 8-inch water main from the booster
pump station to the elevated storage tank and installation of an additional river crossing
pipe. The cost estimate for this alternative is as follows:
Intermediate Booster Pump Station Facilities
1. Booster Pump Station $ 95,000
2. Ground Storage Tank $ 75,000
3. Land(one acre) $ 5,000
4. 25,000 feet 8-inch water main $300,000
5. Telemetry $ 5,000
6 . River crossing pipe(100' @$175/foot) $175,000
Total Construction $665,000 .
Contingencies (10%) $ 65,500
Engineering(15%) $ 98,250
Grand Total: $818,750
In addition to the above mentioned pumping facilities the existing water treatment plant
facilities will still need to be upgraded in the near future. This facility is approximately
25 years old and is not set up for expansion. It is anticipated that expansion of the
existing plant would be as costly as construction of a new facility.
C. New water treatment plant facility
A new water treatment facility is needed to meet future water demands of
the County. This facility would be used to supply water to the northwest portion of the
County as well as supplement the water demands for the remainder portion of the
County. A new water treatment facility would be constructed in the northwest portion of
the County and would save the cost of the installation of an intermediate booster pump
station and additional river crossing pipe to serve the proposed 200,000 gallon 4-H
Center tank.
VI. Proposed Project
A. Design ..
The 4-H Center and elevated water tank is proposed in the Bull Bay area
of Tyrrell County. The new water treatment facility would be constructed in the
Woodley area along NC Highway 64 west of Columbia. The new facility will be
approximately five miles from the proposed water tank and be located in a central
location to serve the County better and supplement the demand of the existing water
treatment facility. It is anticipated the water quality will be similar to the existing system
requiring pressure filtration for iron removal and ion exchange softeners for hardness
4

removal. A new 8-inch water main would be will extend from the treatment facility to
the 4-H Center tank. A project description layout map is presented in Appendix B of the
report.
1. Supply
Ground water from wells will be utilized for the water source.
Test wells will be performed for the actual design requirements for the water treatment
•
plant. Preliminary design of the plant is based on water quality and quantity from
existing wells in the area. Depth of wells in the area is approximately 100-150 feet and
. are high in hardness and iron.
Two 300 gallon/minute wells are proposed. This will allow for a 300 gallon per minute
water treatment plant with 12 hour run time for each well. One acre will be needed for
each well site. The wells will be placed at approximately 2,500 feet to prevent
overlapping of the cone of influence on the wells. A 6-inch water main will be installed
.from the remote well to the water treatment facility. The other well can be located
adjacent to the water treatment plant.
2. Treatment
The water in the area must be treated. Iron and calcium hardness
must be removed to meet State limits. To meet future needs and water quality standards,
a 300 gallon/minute pressure filtration and softening plant is proposed.
Raw water from the wells would first be processed through an aerator. The aerator would
remove odor(hydrogen sulfide)and assist in oxidation of the iron. Two pressure filters
would be needed at 150 gallons per minute per filter. This would be followed by two
cation exchange softening units for hardness removal. Finished water from the plant
would be pumped into an on-site 100,000 gallon ground storage tank. Finished water
high service booster pumps would draw water from the ground storage tank and pump
water into the distribution system and fill the proposed 4-H Center elevated storage tank.
The water treatment facility including filters, softeners, and finished water booster pumps
would be housed in a 2,500 square foot pre-engineered metal building or block building.
Backwash water from the facility is expected to be in the range of 22,000 gallons per day.
It is proposed to install a 6-inch water main to discharge backwash water into the
Scuppernong River. An NPDES Permit will be needed to allow discharge of the
backwash water.
3. Storage
The County has three existing elevated storage tanks. The existing
tanks are as follows:
• 250,000 gallon tank at the existing water treatment plant
5

• 200,000 gallon tank at the prison facility
• 100,000 gallon tank in the Alligator Community area
. The new 4-H Center in Bull Bay will include a 200,000 gallon elevated water storage
tank. The County has an ample supply of water storage to meet the future needs.
4. Distribution
An existing 8-inch water main extends from the existing water
treatment facility to the Woodley area. The proposed water treatment facility is located
in the Woodley area. From this point, existing 6-inch and 4-inch water mains extend to
the Bull Bay area where the proposed 200,000 gallon elevated storage tank is located. A
. 300 GPM facility pumping water to the elevated storage tank in Bull Bay will exceed 125
'psi.
A new 8-inch water main is proposed to extend from the proposed water treatment
facility to the Bull Bay tank. Length of the proposed water main is approximately 25,000
feet. Location of the proposed treatment facilities in the Woodley area will provide an
amply supply of water to the northwest portion of the County while filling the proposed
Bull Bay elevated tank as well as the supplying water through the existing 8-inch water
main to the remaining portions of the County.
•
B. Cost Estimate
A breakdown of the project cost is as follows:
Water treatment plant building 2,500 sq. ft. @ $95/sq. ft. $ 237,500
Water treatment plant equipment lump sum @$250,000 $ 250,000
Water treatment plant electrical lump sum @$140,000 $ 140,000
and controls
Water treatment plant aeration and lump sum @$70,000 $ 70,000

C. Annual Operating Budget
A copy of the annual operating budget is contained in Appendix C of this
report. Water revenues for Fiscal Year 1998-1999 are $392,104. The only immediate
increase in expected revenues are from the proposed 4-H Facility. At an expected 45,000
gallon per month additional revenue is $1,227 per month for a total water revenue of
$393,331.
The expenditures are not expected to increase a great deal immediately because water
production will be a gradual increase. However,several expenditure accounts will
- • increase due to the proposed plant. These expenditure increases are listed as follows:
• Lab test $ 850
• Chemicals $ 1,900
•
• Salt $ 5,400
• Insurance building $ 4,000
• Utilities $ 4,400
• Total $16,550
The net increase in system operating cost is $15,323. Increase in expenditures charged to
1,131 users is an increase of$1.13 per month in the water bills. Average water bills are
presently at$14.79. The expected water bills will be $15.62. The high unit cost bill for
Tyrrell County is$13.02 per month.
•
VII. Conclusion and Recommendation
A new water treatment facility and an 8-inch distribution main to the proposed 4-H
Center elevated storage tank is needed to meet the needs of the Tyrrell County water
system. Total cost of the proposed facilities is$1,874,374. It is recommended that
Tyrrell County apply for the High Unit Grant Application Program through the
Department of Environment and Natural Resources. The present average residential
water bill is$14.79. To be eligible for the high unit cost grant,water bills must exceed
$13.02. These facilities are needed; however,the residents of Tyrrell County cannot
afford an increase in water bills to fund such a project nor does the County have the
bonding capacity to borrow the money. A 100%grant is needed to make this project
feasible.

Northeast North Carolina relies entirely on groundwater for its potable water source. It is
getting increasingly difficult to treat groundwater through conventional methods in this
region. The shallow aquifers that require conventional treatment do_not have sufficient
quantity to meet the needs while the deeper aquifers are too brackish for conventional
treatment. For this reason, many water systems in northeastern North Carolina utilize or
are changing to reverse osmosis treatment.
Tyrrell County and its engineers have major concerns that wells drilled in the proposed
treatment facility area will experience declining water quality due to an upconing of
chlorides from lower aquifers. Our research has indicated that the additional $200,000
available from the Rural Center will provide sufficient funds to upgrade the proposed
treatment facility to a reverse osmosis facility. A reverse osmosis treatment facility will
provide the treatment technology to meet long term diminishing water quality of the
region.
The change in the project scope will be to utilize reverse osmosis treatment in lieu of
conventional pressure filtration and ion exchange softening. This also results in upsizing
the wells from 300 gpm to 400 gpm and upsizing the clearwell from 100,000 gallons to
300,000 gallons. All other design aspects remain the same.

•Re: Reverse Osmosis Discharge,Tyrrell&Dare County
Please find attached a copy of a letter from Mr. Eric T. Weatherly,P.E. of
Hobbs, Upchurch&Associates, regarding the funding and the NPDES permitting of
two proposed water treatment plants. One of the proposed plants is in Tyrrell and the
other in Dare County.Mr. Weatherly indicates that in order for Tyrrell County and
the Stumpy Point Water and Sewer District(SPW&SD)to receive a Clean Water
Bond grant a permit to construct from the Public Water Supply Section(PWSS)
must be issued.In order for PWSS to issue a permit to construct a water treatment
plant a method of disposal of any reject or backwash water is required. In this case,
an NPDES permit would be required. Mr. Weatherly acknowledges that it is
impossible to process the NPDES permit application by the PWSS deadline(July 7,
2000). Mr. Weatherly has contacted Mr. Tony Chen of the Public Water Supply
Section,which has agreed that a letter from the DWQ will be adequate for PWSS to
issue a construction permit. The letter should indicate that"it is possible"for an
NPDES permit to be issued in the aforementioned cases.
I am familiar with both the Tyrrell County and Stumpy Point sites. I believe
that it is not only possible,but also likely that an RO reject water discharge from the
water treatment plants can be permitted. The Tyrrell County site would discharge
directly to Bulls Bay in the Albemarle Sound and the SPW&SD would discharge in
to Stumpy Point Bay in the Pamlico Sound.
It is recommended a letter addressing the possibility of issuing an NPDES
permit for both theses sites be sent to Mr. Weatherly.

SECTION 3
GUIDED BORING INSTALLATION
01. GENERAL:
•
A. Scope: This section includes the installation of the discharge main by guided
boring, including connecting to the existing discharge main. The Contractor will furnish all
labor, components, materials, tools, and appurtenances necessary or proper for the
performance and completion of the contract.
B. General Description of Method: Guided boring is a method of trenchless
construction using a surface launched steerable drilling tool controlled from a mobile
drilling frame, and includes a field power unit, mud mixing system and mobile spoils
extraction system. The drilling frame is sited and aligned to bore a pilot borehole that
conforms to the planned installation of the main. The drilling frame is set back from an
access pit that has been dug (typically at the location of a proposed manhole or other
appurtenance)and a high-pressure fluidjet toolhead that uses a mixture of bentonite clay and
water is launched. Pits are normally dug at the start point and endpoint of the proposed pipe
installation and are used to align the toolhead, attach other equipment, and to collect and
remove excess spoils. Using an electronic guidance system,the toolhead is guided through
the soil to create a pilot borehole. Upon reaching the endpoint joint,the toolhead is removed
and a reamer with the product pipe attached is joined to the drill string and pulled back
through the borehole. In large diameter installations, pre-reaming of the borehole will
usually be done prior to attaching the product pipe for the final pullback. A vacuum spoils
extraction system removes any excess spoils generated during the installation. The
connections,manholes,or other appurtenances are then completed at both the start point and
endpoint locations and the surface restored to its original condition.

SECTION 4
SLIP-ON DIFFUSER CHECK VALVES
01. SCOPE: This section shall include the furnishing of four(4)Diffuser Check Valves
as shown on the drawings and specified herein.
02. SUBMITTALS:
A. Submit six(6)copies of product literature that includes information on the
performance and operation of the valve,materials of construction,dimensions and weights,
elastomer characteristics,flow data,headloss data,jet velocity data,and pressure ratings.
B. Provide shop drawings that clearly identify the valve dimensions.
03. QUALITY ASSURANCE:
A. Supplier shall have at least ten(10)years experience in the manufacture of
"duckbill"style elastomeric valves,and at least five(5)years experience with diffuser
applications,and shall provide references and a list of installations upon request.
04. "DUCKBILL"ELASTOMERIC DIFFUSER VALVES:
A. Diffuser Check Valves are to be all rubber of the flow operated check type
with a slip-on connection. The Check Valve is designed to slip over the specified pipe
outside diameter and attached by means of vendor furnished stainless steel clamps. The port
area shall contour down to a duckbill which shall allow passage of flow in one direction
while preventing reverse flow. The flange and flexible duckbill sleeve shall be one-piece
rubber construction with nylon reinforcement.
B. The Diffuser Check Valves shall provide a variable orifice nozzle to
minimize variation in jet velocity with flow. The jet velocity vs. flow characteristics shall
follow a non-linear curve which maximizes jet velocity at low flow rates compared to fixed
orifice nozzles. Manufacturer shall have flow test data on diffuser check valves obtained by
an independent test facility verifying pressure drop and jet velocity vs.flow.
C. Company name,plant location,valve size,and serial number shall be bonded
to outside of the check valve. Valves shall be manufactured in the USA.

05. FUNCTION:
A. When line pressure inside the valve exceeds the backpressure outside the
valve by a certain amount,the line pressure forces the bills of the valve open,allowing flow
to pass. This restriction causes an increase in the jet velocity of the discharge,while the
shape of the opening creates a flattened plume-shaped discharge pattern to increase
dispersion. When backpressure exceeds the line pressure by at the same amount,the bills of
the valve are forced closed.
06. MANUFACTURER:
A. All valves shall be of the Series TF-D as manufactured by the Red Valve
Co.,Inc.of Carnegie,PA 15106 or approved equal.
07. INSTALLATION:
A. Valve shall be installed in accordance with manufacturer's written

Re: Brine Discharge Line Easement
Dear Mr. Brickhouse:
An easement at the 4-H Environmental Education and Conference Center in Tyrrell County
was approved by the Council of State at its meeting held on July 11, 2000 for your
installation of the brine discharge line to the sound from the planned Reverse Osmosis
Water Plant to be constructed adjacent to the Center. This non-exclusive easement will be
10 feet wide with an additional 10-foot temporary easement provided during construction.
( The enclosed map shown as "Exhibit A" provides the general routing of this line.
Preparation of the easement document will be coordinated with the State Property Office.
A centerline survey of the easement including metes and bounds legal description will be
required from Tyrrell County for inclusion in this document. Please work with Mr. Floyd
Williams, Construction Project Manager of the 4-H Center, on the specific routing along
the property boundary for this survey. His telephone number is [phone]. Also, as
discussed in our earlier meeting and as a condition of this easement, the RO plant and
associated facilities must be screened from direct view from the 4-H Center. I will forward
a copy of the draft easement upon completion.
If you have any questions regarding this easement, please give me a call.
Sincerely,
/
