(1) I have reviewed the total lot area that shows the required septic or on-site waste setbacks.
These have been drawn to scale (attachment 1) siting the appropriate rule that governs this
particular lot situation. NCDENR-DEH rules accompany site plan (attachment 2)
That portion of the lot not in the buffer is fully utilized by home, drive, water supply well
setback, and the existing septic system. The initial system area shown in attachment 1 is a space
efficient system that takes the smallest footprint available for use in N. C. Enclosed is a
manufacturer spec sheet (attachment 3). Also note that the septic field is completely stabilized by
sod (attachment 4).
Also enclosed is the Iredell County GIS of the peninsula showing the area where this lot is
located. The reason this lot has so many space restrictions is because it is the last undeveloped
lot on the peninsula (attachment 5).
You asked for a revised plan. Other than removing the house and replacing it with a smaller
structure, this cannot be done. The house goes from street setback, to lake setback, to sideline
setback, to the installed septic field, including a minimum well setback.
Typically residential septic tank waste with AdvantexTM pretreatment gets to the soil at about
70 mg/1 Nitrogen and 9 mg/1 Phosphorous. By also specifying a NitrexTM pretreatment unit, this
total Nitrogen can be reduced to about 4mg/1 (attachment 6). If necessary, I can submit this
addition to the Iredell County Health Department and they will make it a requirement of both the

plan and permit. Attachment 7 illustrates a waste stream of 60% design flow to show
calculations of N and P applied to the rooting zone in the buffer. Total N of 30.5#/AC is well
below what the vegetative mass in the buffer can assimilate. At a rate of 69#/AC total P the clay
soil will fix the P for complete utilization by the trees. The average NCDA recommendation for
woody plants is 108.9#/AC of N and P, much less than is being applied (attachment 8). The drip
technology used to deliver the waste at a 7" depth on 2'x2' centers with low volume emitters
will assure this. Roots will concentrate around the emitter and take all available nutrients and
water. Attachment 9 shows a typical root ball from under an emitter in a similar field in
Watauga County.
(2) To obtain a variance Ken Bealer Homes will clear Zone 2 and put down sod to better
stabilize this area. This can include a surface swail to slow runoff to Zone 1.
Along the northwest boundary of this lot is approximately 5000 sq. feet of Zone 1 which
could be further enhanced by planting woody shrubs (cross hatched area shown in attachment 1).
If a proposal for such could result in a variance, please let me know.
As an alternative, a request has been sent to NCEEP to see if they have availability
(attachment 10).

(c) An adjusted design daily sewage flow may be granted by the local health department upon a showing as specified
in Subparagraphs (c)(1) through (c)(2) that a sewage system is adequate to meet actual daily'water consumption from
a facility included in Paragraph (b) of this Rule.
(1) Documented data from that facility or a comparable facility justifying a flow rate reduction shall be submitted
to the local health department and the State. The submitted data shall consist of at least 12 previous
consecutive monthly total water consumption readings and at least 30 consecutive daily water consumption
readings. The daily readings shall be taken during a projected normal or above normal sewage flow month.
A peaking factor shall be derived by dividing the highest monthly flow as indicated from the 12 monthly
readings by the sum of the 30 consecutive daily water consumption readings. The adjusted design daily
sewage flow shall be determined by taking the numerical average of the greatest ten percent of the daily
readings and multiplying by the peaking factor. Further adjustments shall be made in design sewage flow rate
used for sizing nitrification fields and pretreatment systems when the sampled or projected wastewater
characteristics exceed those of domestic sewage, such as wastewater from restaurants or meat markets.
(2) An adjusted daily sewage flow rate may be granted contingent upon use of extreme water-conserving fixtures,
such as toilets which use 1.6 gallons per flush or less, spring-loaded faucets with flow rates of one gallon per
minute or less, and showerheads with flow rates of two gallons per minute or less. The amount of sewage
flow rate reduction shall be determined by the local health department and the State based upon the type of
fixtures and documentation of the amount of flow reduction to be expected from the proposed facility.
Adjusted daily flow rates based upon use of water-conserving fixtures shall apply only to design capacity
requirements of dosing and distribution systems and nitrification fields. Minimum pretreatment capacities
shall be determined by the design flow rate of Table I of this Rule.

There are many new developments in ground absorption
sewage disposal system on the market today. The T&J Panel
System is designed to make the most out of the least amount
of space possible. This is made possible by the fuller use of
the more porous top soil and the limited effect of evapotrans-
poration and the wicking action of the block as the effluent
is kept close to the surface of the ground and fused through
the pores of the block to the sidewall area of the drainfield
lines. This more general distribution and wicking allows
for the use of the entire sidewall area and helps prevent the
sealing off of the bottom and lower sidewalls that often occurs
in a conventional system.
A 16 inch high panel is 46 inches long, 8 inches wide, and
weighs about 155 pounds. There is a 6 inch by 6 inch air
chamber at each end of the panel which extends from top
to bottom to ensure aerobic action in each level of the
field lines. Each panel has a storage chamber just below
the top chamber for storage during peak use periods. A 24
inch panel is also available for use in repair or specially
engineered systems.

Although this manual is sectioned for specific user groups, we at T & J Panel suggest
that you familiarize yourself with the complete manual.
Revised Eighth Edition
ENVIRONMENTAL HEALTHSPECL4LISTS
System Design
In the early days of the T & J Panel system, when it was still considered an experimental system, the
primary reason for permitting the Panel System was because of insufficient space for a conventional
system. Now with inclusion in the Sewage Regulations [IONCAC IOA.1956 (3) (a) (ii)], the Panel
System should be considered when: a quality effluent may be needed, space is limited, usable soil is
limited, or there are indications that at some future time space may be needed for other development.
When there is a trend for added development such as additions to homes, pools, or other special
landscaping development the T & J Panel System may prevent insufficient space later. As the
Environment Health Specialist who is designing a system, and you can foresee such a trend of
continued development, the Panel System may be an option the homeowner would like to utilize.
As noted in the regulations a PPBPS is only permitted where soils are suitable, provisionally
suitable, or reclassified provisionally suitable, however only one half of the area needed for a
conventional system is required. This is one reason that the Panel System can help you use the best
soils available on the lot. The system can be gravity fed, pumped to a pressure manifold and gravity
fed into the lines, or pumped to Low Pressure Panel lines. Most of the concepts for a Panel System
layout are the same as for a conventional system. The biggest difference being the aerial area
needed and the quality of effluent being introduced into the ground.
The T & J Panel system can be installed as either gravity, pump to gravity, pump to pressure
manifold, or low pressure pipe distribution system. When designing a pressure system the principles
of low pressure distribution are as described in the LPP manual. There is further discussion on
pressure systems in the installer section of this manual.
Conversion
A three bedroom house with a 0.4 gpd application rate. (The first three steps are the same as for the
conventional system.)
1) 120 gallons per bedroom X 3 bedrooms = 360 gallons per day design flow rate.
2) 360 gallons flow rate / 0.4 application rate = 900 sq. ft. of conventional trench bottom.
3) 900 sq. ft. / 3 ft. wide trench = 300 lineal feet of conventional system.
This conventional layout requires 2700 sq. ft. of area on the lot with another equal area of repair
space for a total of 5400 sq. ft. of suitable usable area. To calculate the size of the T & J Panel
system, the above calculations must be made with an additional fourth step as described in l ONCAC
I OA .1956 (3) (a) (ii) (B) for a PPBPS, (the T & J panel system).
4) 300 lineal feet of conventional system X 0.5 for a 16 inch high Panel System = 150 lineal
feet of T & J Panel System.
-1-
A Panel System requires only a 1200 sq. ft. area on the lot for the system with an equal area for
repair, a total of 2400 sq. ft. With the panel system the installation and repair can go into the same
area as the initial area required for a conventional gravel trench system.
Window Ef)`ect
To prevent hydraulic overload, in the soil aerial space, should always be a consideration for any
system. However, it is especially notable with the Panel System as with any system that reduces the
size of the aerial area drain field. The following is a simplistic example of this concept.
l1

INCORRECT
While both systems have the same lineal footage of trench, the incorrect diagram is not a
desirable design. The effluent must pass through the area A-A' which can cause a strain on that
area and even a failure because of hydraulic overloading.
Distribution
Another extreme would be the use of a long single trench fed from only one end. In the incorrect
example the aerial space is good and the chance of hydraulic overloading is greatly reduced.
However, downline distribution in the panel line will not give optimum treatment.
CORRECT INCORRECT
In the correct example we see that the trench has been fed from multiple points. Because the
panel lines are pit in as level as possible, never exceeding '/4 inch of drain line fall in 10 feet of
run, they feed both ways equally. T & J recommends that no gravity line exceed 50 feet, unless
it is fed from multiple points. In both of these examples, we are specifying the Panel System, but
the logic applies to the conventional system as well.

CORRECT
To calculate the number of 16 inch high panels needed for a 150 foot line, multiply 150' X 12" _
1800", then divide by 52" which is 46 inches for the panel and 6 inches for the space between the
panels in the trench. 1800" / 52" = 34.6 panels, so you would call for 34 panels. (A material
order chart is included in the installer section of this manual.) If there is to be more than one
trench, the sizing of the lines should be as equal as possible with as close to the same number of
panels in each trench as is practical. Environmental Health Specialists should show the panel as
small blocks on the line of the trench.
Backfift
Backfill sand shall be a clean, washed, medium sand that is naturally occurring and falls within
the gradation of ASTM C-33 specification. This specification is one that is used in the ready mix
industry and is readily available in all areas. The second type of sand that you will need is a
clean particle sand to coat the bottom of each panel's top chamber with a bed of sand one inch
thick. This sand is a medium grade of sand blasting sand. Each one hundred pound bag should
cover eight panels. Backfill sand calculations should be taken from the material sheet.
Tar Seals /Foam Sealant
The drawings below illustrate the outer and inner seal. Note that while the outer seal is a
complete seal, the inner seal is only up to the top of the connecting pipe. This is to allow for
over flow of the effluent at peak use periods into the lower air chambers. At this point the air
chamber becomes an additional storage chamber for the effluent. These seals can be inspected
by lifting the caps at the ends of the panels while inspecting the system installation. GE's Space
Invader foam is an approved alternate to tar for these seals. Care should be used not to glue the
caps down with the use of Space Invader. Allow the foam to expand and cure before placing the
cap block on the panel. When using Space Invader foam special care should be used on the inner
seals of the panel not to over fill or under fill this seal.

INSTALLER
The Panel Block Svstem
Generally, on level open land, a Panel System can be installed in about the same time as a
conventional system; however traditionally, Panel Systems have been installed where space and
topography have restricted use of a conventional system. For this reason Panel System
installations have required more time. Many installers enjoy the change of working with panels,
not handling gravel, and the satisfaction of knowing a system being installed where previously a
conventional system was not possible.
Ordering Materials
Enclosed on the following two pages you will find an order sheet for the T & J Panel System and
a materials chart for a 16 inch high Panel System. The distributor in your area will lead you
through these sheets when ordering or pricing the system. For information on the distributor
located closest to you call 704-924-8600 or fax [phone]. After ordering, your panels will
be shipped to the job site banded together on pallets.
Installation Tips
Installation for multiple line systems should begin in the most confining area and be worked to
the more open areas.
I I n l i
l I I ? /? ??' 1
r
LAKE
Above is an example of a multiple line installation. As you can see the installation should begin
with the line marked 1 and proceed to 2, 3, then 4. This procedure will greatly ease material
handling and backfilling. (Note sections of the drain lines should be left uncovered to allow for
inspection of lines when area is confined and return access to lines is limited.)
On the following page are two examples of drain lines on sloping lots. The second drawing
shows the drain line going through a slope making the center of the line deeper in the ground.
This is not a desirable situation. The first drawing shows the drain line going around the slope
keeping the trench depth and cover uniform for the entire length of the line. On slopes, care
should be given to avoid cutting away valuable topsoil in an effort to make straight lines. The
Panel line should be installed on grade with the contour of the natural slope. Panel lines can be
curved to almost any degree.
-5-

CORRECT
Di Lng the Trench

INCORRECT
Start by shooting the grade and marking the contour. Then for a 16 inch panel add 28 inches to
the shallowest or lowest grade that the trench must cross to obtain the trench bottom grade. Now
dig the trench at the elevation derived, checking the grade frequently. The trench should be a
minimum of two feet wide. With the trench open all sidewalls and bottom shall be raked to
bring smeared areas back to their original structure before a light dusting of lime is applied.
Now place a 6 inch layer of backfill sand in the trench and level to grade, then place a 1 x4 or 1 x6
inch board flat on the top of the 6 inch layer or sand. Once more check the grade of the trench
by shooting the top of the board. Once the grade boards have been set, the panels may be set into
the trench by hand or by using the backhoe. Each panel weights about 155 pounds and
placement by hand goes quickly. The panels should be placed about 6 inchs apart in the trench
to obtain equal spacing. Now place 10 to 12 pounds of clean particle sand (medium sand
blasting sand) in the top chamber of each panel to form a bed of sand about one inch thick. Tar
seal rope or Space Invader foam should be placed in the bottom of the U outs to form seals
around the pipe as shown in earlier drawings. Once the Tar Seal or Space Invader foam is in
place a 24 inch section of two inch PR 160 pipe is cut to span from the upper middle top chamber
of the first panel to the upper middle chamber of the next panel. The Tar Seal rope that is used
should be of tar or butyl that is soft and pliable to obtain a watertight seal. Now that the
connection and sealing is complete a block cap is placed on each end of the panel covering all
openings. (These will be delivered with the panels.) The cap block may well serve as an
inspection port at some future date. The trench is ready to be backfilled to the top of the panel
with the same backfill sand used in the trench bottom. With the sand to the top of the panel,
3 should tve- left r hP c r,. taiiC' --.r JliGU::{ be added after the final
inspection.
Most Panel Systems are currently used due to space considerations and caution should be taken
to preserve suitable soil structure and site conditions.

Pump Sizing
Below is a chart to aid in head selection due to friction loss in PVC pipe. In calculating friction
be sure to add 20% for loss in fittings. In the chart below friction loss is per 100 feet of pipe.
The head created by friction loss is added to the elevation head of lift from the bottom of the
pump tank to the top of the highest turn-up.

In addition NITREXTM Filter systems have been operational at seven (7) installations in Canada since
1997 for individual and cluster wastewater systems, along with golf course and farmland runoff
treatment systems. The NITREXTM Filter is under continual development at the University of
Waterloo. Recent tests have confirmed that system start-up after a six month dormancy occurred
without any nitrate laden wastewaters being discharged. The LaPine Oregon Project evaluated two
NITREXTM Filters, along with 16 other technologies. A comparison of all the latest technologies is
presented below for two (2) years of data.

NitrexTM Treatment Performance
The NftrexTM fitter installed at Otis Air Force base has reduced nitrogen in the effluent by an average of 74.1 %
over the two years that it has been in operation. The following figures illustrate the nitrate in the effluent and % of
nitrate removed from the effluent due to the NitrexTM filter. The Table provides the actual data measured by an
independent laboratory. The lower winter 2003 wastewater temperature from the RSF reduced the performance
of the Nkrex filter. The Nkrex filter can be easily modified to overcome the issue.

Burford, Ontario Project
Project Description
Page 6 of 8
A 35 unit senior citizen's complex located in Burford, Ontario has had a NitrexTM Filter system installed since 1999
to produce wastewater effluent with a Total Nitrogen concentration less than 10 ppm that is discharged to a soil
absorption system. For the design flow of 3,500 gallons per day (gpd), wastewater is treated by a septic tank,
then an intermittent sand filter (ISF) is used for pre-treatment and the final disposal goes to a conventional the
bed. Groundwater monitoring wells are located 52 in downstream of the end of the tile beds.

In addition NITREXTM Filter systems have been operational at seven (7) installations in Canada since
1997 for individual and cluster wastewater systems, along with golf course and farmland runoff
treatment systems. The NITREXTM Filter is under continual development at the University of
Waterloo. Recent tests have confirmed that system start-up after a six month dormancy occurred
without any nitrate laden wastewaters being discharged. The LaPine Oregon Project evaluated two
NITREXTM Filters, along with 16 other technologies. A comparison of all the latest technologies is
presented below for two (2) years of data.

NitrexTM Treatment Performance
The NitrexTM filter installed at Otis Air Force base has reduced nitrogen in the effluent by an average of 74.1 %
over the two years that N has been in operation. The following figures illustrate the nitrate in the effluent and % of
nitrate removed from the effluent due to the NitrexTM filter. The Table provides the actual data measured by an
independent laboratory. The lower winter 2003 wastewater temperature from the RSF reduced the performance
of the Nitrex filter. The Nitrex fitter can be easily modified to overcome the issue.

Burford, Ontario Project
Project Description
Page 6 of 8
A 35 unit senior citizen's complex located in Burford, Ontario has had a NitrexTM Fitter system installed since 1999
to produce wastewater effluent with a Total Nitrogen concentration less than 10 ppm that is discharged to a soil
absorption system. For the design flow of 3,500 gallons per day (gpd), wastewater is treated by a septic tank,
then an intermittent sand filter (ISF) is used for pre-treatment and the final disposal goes to a conventional tile
bed. Groundwater monitoring wells are located 52 in downstream of the end of the tile beds.
