Project Summary for:
Crosland Residence at 939 Golf Course Road
Avery County; Linville, NC.
The project is located at 939 Golf Course Road in Linville, NC. in a subdivision on
the east side of Highway #105 North of Linville, NC. The home proposed is a 4
bedroom residence located on a 0.76 acre lot. The Health Department has had
potential buyers interested in the property in the past and has made visits to the
property. Soil investigation has shown that the existing soils are incapable of
sustaining a typical septic system. Further analysis determined that an advanced
system with drip tubing could not be supported either. Therefore, the Health
Department has determined that the site cannot support an on-site disposal system.
A letter to that effect has been included in this application. Foothills Soils (Connie
Adams) has also determined that the existing soils would not support a disposal
system. Foothills Soils Consulting was not asked to make a report since it agreed
with the Health Department findings. The neighboring pieces of property are
developed into homes within the subdivision and adjacent to this property, making
additional acquisition of land for additional disposal very difficult. The online map
from the DWQ shows that there are several existing systems permitted within this
area of the subdivision. I cannot tell if they are direct discharge, only that they are
permitted through DWQ. That map (watershed determination) is also included
with this application.
A copy of the Health Department's findings,is included in this application.
Because the Health Department has declined the site for disposal, a soil report was
not acquired. However, Connie with Foothills is prepared to write one if required.
A new system will be designed for 4 bedrooms at 480 gallons per day. The system
will utilize a 1,000 gallon septic tank and a new treatment facility will be added to
Jtreat the wastewater to TS II standards with a UV light added for the removal of

pathogens. The system will also be installed with de-nitrification "bio-pack"
modules to reduce nitrogen output. The treatment facility will be down stream and
downhill of the proposed water well, which is over 100 feet away. A M-400
Septitech system designed for the 480 gallon system will be installed. The UV
light will be incorporated into the M-400 tank. The M-400 utilizes three sets of
pumps. One set is to remove the small amounts of dead bacteria (microbes) that
have been flushed through the media with the wastewater and have accumulated in
a reservoir on the tank bottom. They are then pumped back to the septic tank for
additional anaerobic digestion (denitrification). As such, sludge and flock do not
accumulate and the processor does not require pumping. This is called the "pump
back" pump. A Gould LSP03 is proposed. A second set is for recirculating the
effluent back through the media to get the TS II treatment levels. A Tsurumi OM2
pump is proposed. The third set is the effluent pumps which are used to pump the
effluent out once the treatment process is complete. The same pump as the pump
back is proposed (the Gould LSP03). This will make maintenance easier having
the same pump specified. These effluent pumps are more than adequate to pump
to the creek as the elevation change is very minor. I used a 10 foot head as a very
conservative number. The system is physically located 7' above the creek and 3'
above the road to assist in preventing any backup of the creek into the M-400 tank.
The creek would flow over the road and further down the hill prior to it backing up
into the effluent pipe of the system. A cleanout is also proposed at the exit of the
effluent pipe to assist with cleaning. The UV light is located on the discharge side
of the M-400 unit so treated effluent is passing through the light. The UV light is
the last stage the effluent passes prior to being discharged. The head losses of the
effluent passing through the UV light are very minor (negligible). I have included
these calculations.
The "Denite Package" will be installed with this unit. This SeptiTech nitrogen
reduction technology first nitrifies wastewater by the aerobic trickling filter
process. Nitrification of the ammonium (NH4) in the wastewater occurs in the
processor as it passes through the media. Nitrified wastewater is then passed into
an anoxic (<2 mg/l dissolved oxygen) environment where a culture of anaerobic
bacteria satisfies their need for oxygen by chemically stripping the oxygen off
other compounds, such as NO3. To promote denitrification within the anoxic
environment, SeptiTech has developed zones of submerged media with the
required conditions of temperature, alkalinity, and BOD levels. Similar to the
aerobic process, the denitrification process is self-adjusting based on demand and
controlled by the PLC within the Control Panel to provide consistent results.

The system utilizes a Septitech Control Panel that has been designed to work for
n this unit. It is a standard panel within a NEMA 4 enclosure setup for the floats,
pumps and internal monitoring of the system. A programmable micro-logic
controller (PLC) activates the recirculation and discharge pumps through a
program that self-adjusts these operations based on actual wastewater flow into the
processor (as monitored by the PLC). The processor constantly evaluates the water
usage and meters out the effluent discharge to the disposal area at the appropriate
interval to assure proper effluent treatment.
As part of the Control Panel, the unit will be provided with telemetry for off-site
monitoring of system performance. The Septitech M-400 is a State approved unit.
The State Certification (through DENR—not DWQ) for the tank has been included
with this submittal along with the NSF certification.
There is not a ground water issue where the tanks are located because of the slope
down to the creek. The units are approximately 7 feet higher than the creek at its
closest point and approximately 12 feet higher than the road. Should the creek
back up (due to a blocked culvert for instance), it would flow over the road prior to
flooding the area of the tanks. Therefore there is minimal if any upward pressure
from groundwater or flooding and as such no anti-floatation has been added to the
plans. There is no need.

Re: Crosland Residence Setback Requirements
This site is extremely small which makes all the setbacks difficult for adherence. The site is 104'
wide at the front and expands out(pie shaped)to 260' at the back. The lot is 185' deep from
front to back. We have worked with the Architect to place the residence in a location that makes.
sense for the lot and allows maximum distance for setbacks. The 50' setback off the property
(-l lines(including the RfW) was added to the plans. The water wells were located on the adjoining
lots and were added to the plan with 100' circular setbacks added. The remaining setbacks are
for the creeks. There is one main creek that runs through the middle of the property. This is the
creek that is to be used for disposal. It has a watershed of about 104 acres with springs feeding.
I have observed this creek during the winter and summer months and found it always flowing
well at all times. As you are looking at the lot from the front,there is a small drainage way to the
left with a small watershed. This creels is a dry weather creek, adds minimally to the total flow
at the road but is located far to the left more than 50' away from the proposed units. There is
another dry weather creek on the far right of the property (near the proposed water well). It has a
very small watershed of about 0.5 acres. The 50' setbacks are required off of"Surface Waters"
which I am assuming are the blue lines on an USGS map or lines located on the watershed
classification map on the DWQ website(I can't find a definitive definition). None of these lines
show up on either map and a copy of both maps are included in this submittal. However, a 25'
setback is being maintained, in addition the system is located approximately 10' higher than the
road so it is virtually impossible for the creeks to back up to even the bottom of the units. If the
culvert were to be blocked the flow of water from the creeks would flow over the road and never
back up into the property. The offset from the house is approximately 60'. The control panel is
located at the unit and is within a few feet of the driveway for easy maintenance and visibility.
If I can be of any further service,please do not hesitate to call.

In addition, any site utilizing these systems shall have sufficient alkalinity to perform the
proper amount of nitrification. The influent also shall not have a pH, or toxins that
significantly inhibit microbial growth.
3. This controlled demonstration is initially limited to 200 systems with design flows of up
to 3,000 gallons per day. Prior to the approval of any individual system under the
controlled demonstration approval, the manufacturer of all proposed tanks most be
identified and tank construction details must be State-approved,as typically required for
generically approved Residential Wastewater Treatment Units(previously termed
"ATUs").
4. Use of SeptiTech pretreatment systems where the overall system has a design flow
exceeding 3,000 gallons per day may be permitted after approval by the State on a case-
by-case basis in accordance with the Large Systems State Review/Approval Process
(Rule 15A NCAC 18A.1938).
B. ADVANCED TREATMENT PERFORMANCE STANDARDS(TS-II)*
O1/18/06

The Process Science of the SeptiTech®System:
Summary
SeptiTech®uses an enhanced recirculating biological trickling filter system in a treatment process that is
optimized to remove a high percentage of BOD, TSS, and nitrogen from wastewater through aerobic and
anacrobic degradation. The SeptiTech processor is added to a conventional system between the septic
tank and final soil absorption system(typically a leach field).
Initially, raw wastewater passes through a baffled septic tank, sized according to state code, where a
portion of the solids and grease are separated out. Wastewater flows (typically via gravity) from the
septic tank into the reservoir of the processing tank beneath the trickling filter. The SeptiTech treatment
process uses unique characteristics of a patented filter media to construct a trickling filter in which the
treatment occurs in the mixed-liquor as it passes though the filter. The filter consists of a bed of highly
permeable hydrophobic media situated over a reservoir into which the percolate drains. Within the
reservoir is a pump that distributes a combination of percolate and newly added wastewater from the
baffled septic tank to the top of the media.
\ SeptiTech residential models use polystyrene hydrophobic bead filter media, which occupy the upper
Cl portion of the treatment unit. Due to the hydrophobic nature of the media, microbes present in the
wastewater do not strongly attach to the media, but are rather entrained within the wastewater as it flows
through the media. In this suspended state, the microbes use and transform the nutrients and organic
materials provided by the constant supply of fresh wastewater to form new cell mass. The open spaces
within the media allow air to freely pass through,providing ample oxygen to support the microorganisms.
The percolate from the filtering process drains into the reservoir for further recirculation (approximately
70 times/day) or discharge. Several times per day, a portion of the wastewater in the reservoir is pumped
back to the septic tank where denitrificatiion occurs. Nitrification of the ammonium in the wastewater
occurs in the liquor as it passes through the media.
The timing and sequence of the recirculation of wastewater in the lower collection reservoir, as well as
the recirculation of a portion of the waste back to the septic tank, is controlled by a programmable logic
controller (PLC). The PLC also controls the discharge to the leaching system. A more specific
description of the process is provided as follows:
How the Standard SeptiTech®System works:
Step 1 Wastewater is discharged from the home or business to a partitioned septic tank where
solids settle and begin to undergo anaerobic decomposition. The decanted effluent flows into the
SeptiTech processor tank for treatment.
Step 2 Wastewater from the septic tank enters the processor and collects in a reservoir at the base
of the tank where it mixes with treated water. Wastewater is pumped up to the treatment area
above the reservoir where outside air is passively drawn into the wastewater stream. Oxygenated
U wastewater is uniformly sprayed over the media by low-pressure spray nozzles. The media
consists of polystyrene beads that provide a hydrophobic surface and an exceptionally high

treatment area to wastewater volume ratio. The microbes residing in the pore spaces of the filter
beads break down pollutants in the wastewater as it migrates downward through the media and
back into the reservoir below. The wastewater can be circulated through the filter media 70 or
more times in a 24-hour period by the recirculation pump.
A programmable micro-logic controller (PLC) activates the recirculation and discharge pumps
through a program that self adjusts these operations based on actual wastewater flow into the
processor (as monitored by the PLC). The processor constantly evaluates the water usage and
meters out the effluent discharge to the soil absorption system in equal doses over a 24-hour
period(a dosing schedule can be customized to the project specification).
SeptiTech processors are sized based on the projected design flow with additional capacity to
accommodate wastewater surges (morning and evening flows, special events, etc). Under surge
conditions,the PLC senses the increased flow into the system and adjusts the treatment process to
gradually accommodate the accumulated surge flow while maintaining treatment effectiveness. If
the PLC senses reduced flow, it will ratchet the system down, and after several days enter"sleep
mode"during which the processor only operates long enough to maintain the microbe culture.
SeptiTech processing starts automatically with any wastewater input. The recirculation system
then remains in operation,continuing to automatically reset as necessary,as long as wastewater is
discharged into the processor or until the entire accumulated surge flow has been discharged.
Microbes have a short life cycle, flourishing and dying within a few hours. Due to the unique
physical characteristics of SeptiTech's patented media, the wastewater and microbes do not wet
or strongly adhere to the media surfaces, thereby reducing the potential for the media clogging.
1 Instead of being stationary, the microbes migrate along with the wastewater increasing their
degradation effectiveness. Dead microbes are flushed through the media with the wastewater mid
drain into the reservoir at the base of the processor tank. A "pump-back" system periodically
pumps them back to the septic tank for additional anaerobic digestion (deaitrification). As such,
sludge and flock do not accumulate and the processor does not require pumping,
Step 3 After completing the prescribed treatment process in the processor, the treated water is
time dosed to the disposal field to insure small frequent dosing of the field and proper absorption
by the soil. In addition, pressurized delivery to the field allows placement of the disposal
trenches all in one area or in several mini-disposal areas on the same lot.
Step 4 Finally, SeptiTech disposal trenches lie nearer to the surface of the ground than in a
standard leach field to enable the action of soil microbes to further polish the effluent.
In addition to our standard biological trickling filter processor, SeptiTech systems can provide enhanced
pathogen destruction and can further reduce total nitrogen through the use of complimentary ultraviolet
(UV)sterilization and Denitri&cation processes,respectively.
UV Sterilization
Typical residential wastewater carries fecal coliform at a concentration of 10' to 109 colonies per 100
milliliters(cot/100 ml)of wastewater'. Standard SeptiTech processors reduce this concentration to levels
ranging from less than 10 to 1,000 cot/100 ml.

However, in certain applications (e.g, close proximity to surface water, water supply wells, irrigation
disposal, etc.) a further reduction of bacteria and viruses may be desired. Due to the clarity of the
effluent from the SeptiTech processor,UV sterilization technology can be used to destroy the majority of
the pathogens remaining. This technology is currently installed in over sixty SeptiTech systems in a
number of states including several coastal islands. Fecal coliform concentrations typically range from
non-detectable to 0.5-col/100 ml and average 0.1-col/100 ml. Actual concentrations depend on variations
in wastewater strength and clarity. To produce a more consistently low coliform concentration (less than
0.05 col/100 ml), SeptiTech has developed an enhanced UV process that is being used in several
commercial systems.
Denitrifcation
For critical resource areas that exhibit a high degree of sensitivity to the effects of nitrogen loading,
SeptiTech has developed a denitrification process to further enhance total nitrogen removal during
pretreatment. The SeptiTech denitrification systems have been proven to remove a larger percentage of
total nitrogen by combining the nitrifying capabilities of our aerobic biological trickling filter system with
an enhanced deninification procedure.
The SeptiTech nitrogen reduction technology first nitrifies wastewater by the SeptiTech aerobic trickling
filter process. Nitrification of the ammonium(NH4) in the wastewater occurs in the processor as it passes
through the media. Nitrified wastewater is then passed into an anoxic (>2 mg/l dissolved oxygen)
environment where a culture of anaerobic bacteria satisfies their need for oxygen by chemically stripping
the oxygen off other compounds,such as NO, To promote denitrification within the anoxic environment,
SeptiTech has developed zones of submerged media with the required conditions of temperature,
alkalinity, and HOD levels. Similar to the aerobic process, the denitrification process is self-adjusting
based on demand and controlled by the PLC to provide consistent results.
SeptiTech's nitrogen reduction technology has completed a full year of verification testing under the US
EPA Environmental Technologies Initiative, Source Water Protection Program. This testing was designed
to verify nutrient reduction of the SeptiTech treatment technology and was being conducted by the
Barnstable County Department of Health at the Massachusetts Septic System Test Center in Bourne.
During the testing, the SeptiTech system was loaded with influent wastewater from a sanitary sewer.
SeptiTech's nitrogen reduction capability was measured by constituents that demand oxygen for treatment
(BOD and CBOD), and nitrogen species (TIN,NH4, NOi,and NOn- Operational characteristics such as
labor to perform maintenance, maintenance tasks, durability of the hardware, noise and odor production
were also monitored. Effluent testing showed CBOD5 and TSS was 98% removed. Average Total
Nitrogen in effluent was 14 mg/l. A full report for this testing is posted on the EPA (www.epa.gov/etv)
and NSF(www.nsforg/ety)web sites.

ABSTRACT
(� Verification testing of the SeptiTech? Model 400 System was conducted over a twelve month period at
the Massachusetts Alternative Septic System Test Center(MASSTC) located at Oda Air National Guard
Base in Bourne, Massachusetts. Sanitary sewerage from the base residential housing was used for the
testing. An eight-week startup period preceded the verification test to provide time for the development of
an acclimated biological growth in the SeptiTech? System. The verification test included monthly
sampling of the influent and effluent wastewater, and five test sequences designed to test the unit
response to differing load conditions and power failure. The SeptiTech? System proved capable of
removing nitrogen from the wastewater. The influent total nitrogen(TN), as measured by TKN,averaged
39 mg/L, with a median of 39 mg/L. The effluent TN (TKN plus nitrite/nitrate) concentration averaged
14 mg/L over the verification period,with a median concentration of 14 mg/L,which included an average
TKN concentration of 6.8 mg/L and a median concentration of 5.7 mg/L. The system operating conditions
(pumps and float settings)were controlled by a programmable logic controller(PLC),which was adjusted
at the end of the startup period and then remained constant during the test. All mechanical equipment,
pumps, level switches, alarms, etc, operated properly throughout the test. There were two servic a calls
during the test.During the first call, eight months into the test,the system was cleaned and the PLC reset.
The second call for a high water alarm determined that the effluent pipe had collapsed due to an
installation problem not related to the system itself. After a lightning strike at the test site,the modem for
the PLC was replaced.
TECHNOLOGY DESCRIPTION
The following description of the SeptiTech System was provided by the vendor and does not represent
l verified information.
-J The SeptiTech®System is a two stage treatment technology,based on a fixed film trickling filter,using a
patented highly permeable hydrophobic media. The first stage of treatment occurs in the primary tank(for
Us test a 1,500 gallon two compartment septic tank, standard unit uses a 1,000 gallon tank) in which the
solids are settled and partially digested. The second stage of the SeptiTech? System, is a processor that
provides secondary wastewater treatment. Microorganisms present in the wastewater grow within the
media, using the nutrients and organic materials provided by the constant supply of fresh wastewater to
form new cell mass. Air is drawn into the system via an air intake pipe at the top of the SeptiTech System.
Ventarls located in the sprinkler head distribution piping aerate the wastewater sprayed onto the media.
The system does not have a fan or compressor.
The SeptiTech® System is designed to remove total nitrogen from the wastewater by nitrification and
denitrification.Nitrification occurs in the second stage of the SeptiTech System,where ammonia nitrogen
is converted to nitrite and nitrate (predominately nitrate), while deninification occurs in the
anaerobic/anoxic primary tank. According to SeptiTech,denitrification also occurs in the BioPack SF 30
Random Stack Media used in the system tested,which floats in the reservoir below the aerobic media.
The verification testing was performed using a full scale, commercially available unit, which was
received as a self-contained system ready for installation. Wastewater from the septic (primary) tank
flows by gravity to the Processor reservoir section,located below the filter media. There are four pumps
located in the reservoir. One pump recircutates wastewater from the reservoir to the top of the Processor,
where the wastewater is sprayed over the filter media. The second and third pumps are used to retain
wastewater and solids from the reservoir back to the septic tank. The fourth pump is for the discharge of
treated wastewater to the disposal location. The SeptiTech® Model 400 System is supplied with a PLC,
U which controls the frequency and duration of pump operation, as well as all alarm functions, data
collection,and communication packages.

VERIFICATION TESTING DESCRIPTION
Test Site
The MASSTC site is located at the Otis Air National Guard Base in Bourne,Massachusetts.The site uses
domestic wastewater from the base residential housing and sanitary wastewater from other military
buildings in testing. A chamber located in the main interceptor sewer to the base wastewater treatment
facility provides a location to obtain untreated wastewater. The raw wastewater, after passing through a
one-inch bar screen, is pumped to a dosing channel at the test site. This channel is equipped with four
recirculation pumps that are spaced along the channel length to ensure mixing,such that the wastewater is
of similar quality at all locations along the channel. Wastewater is dosed to the test unit using a pump
submerged in the dosing channel. A programmable logic controller (PLC) is used to control the pumps
and the dosing sequence or cycle.
Methods and Procedures
The SeptiTech® System was installed by a contractor, with assistance from the BCDHE support team, in
June 2001. The unit was installed according to installation instructions supplied by SeptiTech, Inc. On
June 14, 2001, the primary tank was filled with wastewater and the dosing sequence began. An eight-
week startup period allowed the biological community to become established and the operating conditions
to be monitored. The standard dosing sequence was used for the entire startup period.
The system was monitored during the startup period, including visual observation of the system, routine
calibration of the dosing system, and collection of influent and effluent samples. Three sets of samples
lam. l were collected for analysis. Influent samples were analyzed for pH, alkalinity,temperature,BODs,TEN,
NH3,and TSS. Effluent samples were analyzed for pH,alkalinity,temperature, CBODs,TEN,NH3,TSS,
dissolved oxygen,NO2 -,and NO3 _-
The verification test consisted of a twelve-month test period, incorporating five sequences with varying
stress conditions simulating real household conditions. The five stress sequences were performed at two-
month intervals, and included washday, working parent, low load,power/equipment failure, and vacation
test sequences. Monitoring for nitrogen reduction was accomplished by measurement of nitrogen species
(TKN, NH3, NO,NO3), Biochemical oxygen demand (BODs) and carbonaceous biochemical oxygen
demand (CBODs) and other basic parameters (pH, alkalinity, TSS, temperature) were monitored to
provide information on overall system performance. Operational characteristics, such as electric use,
residuals generation, labor to perform maintenance, maintenance tasks, durability of the hardware, noise
and odor production,were also monitored.
The SeptiTech®Model 400 System has a design capacity of 440 gallons per day.The verification test was
designed to load the system at design capacity (f 10 percent) for the entire twelve-month test, except
during the low load and vacation stress tests. The SeptiTech® System was dosed 15 times per day with
approximately 29-30 gallons of wastewater per dose. The unit received five doses in the morning, four
doses mid-day, and six doses in the evening. Dosing volume was controlled by adjusting the pump run
time for each cycle, based on twice weekly pump calibrations. Volume per dose and total daily volume
varied only slightly during the test period. The daily volume, averaged on a monthly basis, ranged from
432 to 449 gallons per day. This was within the range allowed in the protocol for the 440 gallons per day
design capacity.
U The sampling schedule included collection of twenty-four hour flow weighted composite samples of the
influent and effluent wastewater once per month under normal operating conditions. Stress test periods

were sampled on a more intense basis with six to eight composite samples being collected during and
following each stress test period. Five consecutive days of sampling occurred in the twelfth month of the
verification test. All composite samples were collected using automatic samplers located at the dosing
channel (influent sarnple) and at the discharge of the unit. Grab samples were collected on each sampling
day to monitor the system pH, dissolved oxygen,and temperature.
All samples were cooled during sample collection, preserved, if appropriate, and transported to the
laboratory. All analyses were performed according to "Standard Methods for the Examination of Water
and Wastewater,"19n'Edition, 1998.Washington,D.C. or other EPA approved methods. An established
quality assurance/quality control (QA/QC) program was used to monitor field sampling and laboratory
analytical procedures. QA/QC requirements included field duplicates, laboratory duplicates and spiked
samples, and appropriate equipment/instrumentation calibration procedures. Details on all analytical
methods and QA/QC procedures are provided in the full Verification Report.
PERFORMANCE VERIFICATION
Overview
Evaluation of the SeptiTech® Model 400 System at MASSTC began on June 14, 2001, when the system
pumps were activated,and the wastewater dosing started. Three samples of the influent and effluent were
collected daring the startup period, which continued until August 13, 2001. Verification testing began at
that time and continued for twelve months,until August 12, 2002.During the verification test, 54 sets of
samples of the influent and effluent were collected to determine the system performance.
startup
Overall, the unit started up with no difficulty. The installation instructions were easy to follow and
C1 installation proceeded without difficulty. SeptiTech representatives setup the PLC, which controlled all
recirculation, recycle, and discharge pump tines. No changes were made to the unit during the startup
period, and no special maintenance was required.
The SeptiTech® System removed CBODS and TSS after the first three weeks of operation,and continued
to improve over the next five weeks.At the end of the eight week startup,effluent CBODs was<2.0 ni
and TSS was 2 mg/L. The effluent TN concentration dropped from 24 mg/L after three weeks of
operation to 85 mg/L at the end of the startup period. Influent TN concentration ranged from 30 to 42
mg/L during this time. Both the nitrification and denitrification processes were established as shown by
the effluent TKN and nitrate concentrations of 2.3 mg/L and 6.0 mg/L, respectively. During the startup
period, ten percent of the treated wastewater was being recycled to the septic tank. Shortly after the end of
the startup, SeptiTech changed this recycle ratio to twenty percent by adjusting the pump rates in the
PLC. The discharge pimp rate was also adjusted to account for daily dosing of the system at full design
flow.No other changes were made to the system.
Verification Test Results
The sampling program emphasizes sampling during and following the major stress periods. This results in
a large number of samples being clustered during five periods, with the remaining samples spread over
the remaining months(monthly sampling). Both average(mean)and median results are presented, as the
median values compared to average values can help in analyzing the impacts of the stress periods.In the
case of the SeptiTech® System results, the median concentrations for ammonia nitrogen are somewhat
lower than the average concentrations due to reduced nitrification efficiency from February through May,
which impacted the twelve month average concentration.
J l The TSS and BODs/CBODS results for the verification test, including all stress test periods,are shown in
LJ Table 1. The influent wastewater had an average BODS of 250 mg/L and a median BOD$ of 240 mg/L.

The TSS in the influent averaged 150 mg/L and had a median concentration of 140 mg/L. The effluent
showed an average CBOD, of 5.4 mg/L with a median CBODs of 4.7 mg/L. The average TSS in the
effluent was 3 mg/L and the median TSS was 2 mg/L. CBODs concentrations in the effluent typically
ranged from 1 to 10 mg/L, and TSS ranged from 1 to 10 mg/L, except for two sampling days during the
twelve month verification test.

influent wastewater had an average TKN concentration of 39 mg/L,with a median value of 39 mg/L, and
an average ammonia nitrogen concentration of 24 mg/L, with a median of 24 mg/L. The average IN
concentration in the influent was 39 mg/L (median of 39 mg/L), based on the assumption that the nitrite
and nitrate concentrations in the influent were negligible. The effluent had an average TKN concentration
of 6.8 mg/L and a median concentration of 5.7 mg/L. The average NH3-N concentration in the effluent
was 5.1 mg/L and the median value was 2.4 mg/L. The nitrite concentration in the effluent averaged 0.32
mg/L. Effluent nitrate concentrations averaged 6.7 mg/L with a median of 7A mg/L. Total nitrogen was
determined by adding the daily concentrations of the TKN (organic plus ammonia nitrogen), nitrite, and
nitrate. Average IN in the effluent was 14 mg/L (median 14 mg/L) for the twelve month verification
period. The SeptiTech® System averaged a 64 percent reduction of TN for the entire test, with a median
removal of 64 percent.

Verificadnn Test Discussion
By the end of the eight-week startup period and start of the verification test, the system was operating
with an acclimated biomass for both nitrification and denitrification. From August to December, the TN
reduction was typically in the 61 to 78 percent range with TN effluent concentrations of 8 to 11 mg/L.
The washday stress test performed in Umber 2001 did not appear to have an impact on nitrogen
Ureduction. Likewise, in December 2001, the working parent stress test was performed and the

performance of the unit remained steady during and following the stress period. In January and early
February, the normal monthly samples showed a decrease in nitrification efficiency as measured by
increases in TKN and ammonia in the effluent, to 18 mg/L and 14 mg/L respectively. TN in the effluent
increased to 20 mg/L in early February, during a period that corresponded to lower wastewater
temperatures and outside air temperatures.
The low load stress test was started on February 18 and was completed on March 10, 2002. During the
months of February and March,which included the stress test,the IN concentration varied from 7.5 to 17
mg/L. Nitrification was still occurring,but at lower efficiency than during the previous five months. This
also corresponded with the time frame with low effluent temperatures. At the end of the stress test, the
system was still reducing IN concentrations. It does not appear that the low load stress test had a direct
impact on the system, as the reduced nitrification efficiency started in the four weeks prior to the stress
test. The post stress test period from mid-March through May showed consistent results with TN
concentrations in the 15 to 18 mg/L range, except for one day at 27 mg/L. The power/equipment stress
test was performed from May 6 to 8, 2002, with no apparent change in the effluent quality in the post
stress test monitoring period.
A major change in performance occurred in late May or early June. The June 5 sampling showed TN
concentrations reduced to 10 mg/L, and both TKN and ammonia concentration in the effluent decreased
as well (6.0 mg/L and 3.7 mg/L, respectively). The nitrification process had improved and was reducing
the ammonia concentrations to levels similar to the first five months of the test.As the TKN and ammonia
levels decreased, the nitrate levels began to increase in the effluent, indicating that while the
denitrification process was removing some nitrate, it was not removing the increased concentration
produced by the improvement in nitrification.
1 The vacation stress test started on July 8 and continued through July 16, 2002. During this stress test,
there was no wastewater dosed to the system. The TKN and ammonia levels remained low in the post
stress monitoring period but the nitrate levels increased from 9 to 15 mg/L. During this period nitrate was
the main contributor to the effluent TN concentration,which ranged from 16 to 24 mg/L. It is not clear if
the vacation stress test had a direct impact on the denitrification process, as the increasing nitrate levels
began to occur when the nitrification process improved prior to the start of the vacation test.It is possible
that the nitrate levels would have been higher, even if the stress test was not performed. However, the
lack of flow during the vacation stress test reduced the amount of recycle flow from the SeptiTech
reservoir to the septic tank. Therefore,there was less nitrified wastewater being recycled,which may have
impacted the response time for the denitrifying organisms.
The system performance remained consistent for the duration of the verification test. The TKN and
ammonia nitrogen effluent concentrations were consistently low and similar to the first five months of the
verification test. The nitrate levels remained in the 13 to 15 mg/L range and the IN concentration in the
effluent ranged from 14 to 20 mg/L. Alkalinity concentration in the effluent remained lower at 50 mg/L.
It is not clear why the denitrification efficiency was lower throughout the July and August period as
compared to the previous August through December period.
Over the twelve-month test, the system did exhibit some instability in the individual nitrogen removal
mechanisms, i.e. the nitrification and denitrification processes,particularly during December 2001 to July
2002. These changes could be due to stressors not apparent from the data. Despite these changes,the
process continued to remove TN,providing an overall stable effluent quality for TN. The verification test
provided a sufficiently long test period to collect data that included both a long run of steady performance
by the SeptiTecho System and a period of reduced nitrification and denitrification efficiencies. During the
ll five months following startup, the TN removal was in the 60 to 80 percent range, with effluent
\_J concentrations typically in the 8 to 11 mg/I,range. The SeptiTech System continued to remove TN in the
02/04/WQPC.SWP Time accompanying notice is an integral part of this verification statement April 2003
vs'i

later periods, even though the nitrification or denitrification processes were not operating as efficiently.
During the last six months of the verification test, the TN removal was in the 32 to 82 percent range,with
most results in the 50 to 60 percent range. Effluent TN concentrations ranged from 10 to 27 mg/L, with
most concentrations in the 15 to 20 mg/L range. The net effect of the lower performance in these later
periods increases the average effluent TN concentration for the verification test to 14 mg/L.
Operation and Maintenance Results
Noise levels associated with mechanical equipment were measured once during the verification period
using a decibel meter.Measurements were made one meter from the unit, and one and a half meters above
the ground, at 900 intervals in four(4)directions. The average decibel level was 60.0, with a minimum of
589 and maximum of 61.5. The background level was 37.7 decibels.
Odor observations were made monthly for the last eight months of the verification test. The observations
were qualitative based on odor strength (intensity) and type (attribute). Observations were made during
periods of low wind velocity (<10 lmots),at a distance of three feet from the treatment unit, and recorded
at 90' intervals in four directions. There were no discernible odors during any of the observation periods.
Electrical use was monitored by a dedicated electric meter serving the SeptiTech® System. The average
electrical use was 8.4 kW/day. The electrical use included a heater for the PLC, which was located
outside at the test site. In normal applications,the PLC is placed in the home and an auxiliary heater is not
needed. The SeptiTech® System does not require or use any chemical addition as part of the normal
operation of the unit.
During the test,no mechanical problems were encountered with the operation of the system. The system
was cleaned after eight months by spraying water over the nozzles and media. This cleaning was
(-l performed when a service call was placed to SeptiTech in April 2002,based on site operators observing a
lack of sound coming from the unit. During the service call, no problems were found with the unit. The
PLC was reset and the system continued in operation.In June 2002,a high water alarm sounded and a call
was placed for service. SeptiTech responded the next day and found the discharge pipe had collapsed. hi
addition, lightning had struck the test site, damaging the modem and causing fire PLC to enter a "safe"
mode. The discharge pipe was repaired, a new modem installed, and the PLC reset. The discharge pipe
failure was apparently due to improper soil preparation and was not related to the system itself. No
changes or adjustments were needed to the float switches or pumps after the initial changes following the
startup period.
The treatment unit appeared to be of durable design and also proved to be durable during the test. The
polyethylene piping used in the system meets the needs of the application. Pump and level switch life is
always difficult to estimate,but the equipment used is made for wastewater applications. The only trouble
with the PLC was when lightning hit the site,at which time the modem was replaced to reestablish remote
communications.
Quality Assurance/Quality Control
NSF International completed QA audits of the MASSTC and BCDHE laboratory during testing. NSF
personnel completed a technical systems audit to assure the testing was in compliance with the test plan,a
performance evaluation audit to assure that the measurement systems employed by MASSTC and the
BCDHE laboratory were adequate to produce reliable data, and a data quality audit of at least 10 percent
of the test data to assure that the reported data represented the data generated during the testing. In
addition to quality assurance audits performed by NSF International, EPA QA personnel conducted a
quality systems audit of NSF hrtermational's QA Management Program, and accompanied NSF during
audits of the MASSTC and BCDHE facilities.

Re: Crosland Residence UV Light Analysis
UV lights of a low flow nature are typically a low pressure type, short wave,mercury vapor discharge
tube that produces ultraviolet wavelengths lethal to microorganisms. The low pressure allows the
units to run with less power and thereby generating less heat for longer life of the bulbs. The Emperor
Aquatics UV "High Output' Light has been specified for this project.
The spectrum of UV light that is lethal is called UV-C. This includes a wavelength range within 240-
280 nm. A wavelength around 254 to 264 is considered ideal. This lamp is set to 254 rum.
Different microorganisms are extinguished at different doses. The larger"pests"take longer. Fecal
Coliforms are extinguished at near 6600 µWs/cm. This lamp has a range up to 30,000 µWs/cm.
Although there is a wide spectrum of bacteria,viruses and protozoa,most of the"pests"are
extinguished between 2,000 and 20,000. Having a range up to 30,000 µWs/cm,assures that the
germicidal action is most effective across this wide range. For this application, fecal coliforms are
most important,which have a dose requirement of about 6600 µWs/em. This is well within range.
The glass plays an important function in the effectiveness of the lamp in that the glass can absorb the
UV-C wavelength. The hard quartz glass is most effective and is utilized in the"high output'unit.
An additional coating"L" is added to the glass that adds resistance to"solarization" so that the bulb
remains highly effective for longer periods.
The Emperor Smart HQ UV Light has been submitted for review because of its ability to be installed
in the vertical position. It clearly has the UV qualifications to be effective. The requirements for
vertical placement are spelled out in the installation guidelines with a warning to insure the power
head is above the water line. The power unit cannot be submerged. This note has been added to the
plans. This unit is acceptable for use in this application and is accepted for use on this project.
Sincerely,
Michael Lash, PE.

,ULTRAVIOLET DISIFECTiON,SYSTEM)
System Description
SepfiTech has made a recent change in the preferred manufacturer of ultraviolet(UV)
disinfection system for use in systems that require disinfection prior to discharge. The
reason for the recent change is that the manufacturer of the UV unit previously used
(Siemens Sunlight Systems UV)has been discontinued by the manufacturer and is no
longer available.
Therefore, SepfiTech has chose to use the Emperor Aquatics Smart High Output UV
Sterilizer model 025050/50. This unit is rated at the following specifications:
Water Flow Rate: 1,560— 1,980 gph(26—33 gpm) -
Output: 30,000 µWs/cm'
Operating pressure: 20 psi
J Voltage: 120 VAC @ 6014z
No. Lamps/Watts: I lamp @ 50 watts
The UV unit is rated for 26-33 gpm at 20 psi operating pressure. SepfiTech will provide
a flow restrictor and pressure regulator on the discharge of the pump in order to ensure ',..
that the operating parameters and not exceeded during operation.
A technical cut sheet,installation guide and operation and maintenance manual from the
manufacturer have been provided as part of this memo.
Control and Alarm
The operation of the UV unit is the same as it was previously for the Siemens Sunlight
Systems product. The control panel is outfitted to provide power to the UV unit along
with a current sensor. Power to the UV unit is on all the time as long as power to the
control panel is provided. The current sensor is used to detect that current is being drawn
from the UV bulb. If the bulb was to fail to operate, current would no longer flow to the
bulb,and an alarm would be triggered at the control panel as the current sensor would no
longer detect current flow. ',..
;J I'

Frictional Losses
Frictional losses through the UV unit are minimal since the UV chamber is larger than
the discharge piping used with the discharge assembly. The UV unit has 2-inch inlets
and a 5-inch chamber. Based on calculations using factors from Cameron Hydraulic Data
handbook,the total frictional head loss assuming a flow rate of 30 gpm is 0,00856 R
(assumed to be negligible). Head loss calculations are attached.

Subject: Low-flow characteristics for unnamed tributary to Linville River in Avery County...Re: Google Earth
Placemark: -GE3B.kmz
Ms. Adams,
In response to your inquiry about the 7010 and 30Q2 low-flow characteristics for an unnamed tributary to the
Linville River in Avery County, the following information is provided:
A check of the low-flow files here at the USGS North Carolina Water Science Center does not indicate a
previous determination for your specific point of interest on the unnamed tributary to the Linville River. The
files do indicate previous determinations at two nearby locations on the same unnamed tributary completed
in 1982. The 7Q10 discharges were estimated at less than 0.05 cfs, and the 30Q2 discharges were
estimated at approximately 0.1 cfs
Inspection of the topographical quad map does not indicate the presence of a stream but rather a dry
channel coming from the ridge line at Grandfather Mountain.
In the absence of discharge records sufficient for a low-flow analysis, estimates of low-flow discharges are
C -\ determined by assessing a range of low-flow yields(expressed as flow per square mile drainage area, of
l cfsm)at nearby locations where low-flow discharges have been determined.
A preliminary assessment of available information at five nearby USGS partial-record sites where low-flow
discharges were published in a statewide low-flow report for North Carolina(Giese and Mason, 1993;
available online at
http�/tpubs.er.usas.gov/#search�advance/paqe=l/pacie size=100/series cd=WSP/report number=2403 0)
indicates that 7010 low-flow yields for streams in vicinity of your point of interest range from about 0.22 to
0.40 cfsm(average 0.31 cfsm). The regional relations presented in the above-referenced report for
Hydrologic Area 10 indicate that a 7Q10 low-flow yield (using a drainage area 0.5 sgmi and mean annual
runoff 2.5 cfsm) is between 0.35 and 0.4 cfsm.
In a similar manner, the 30Q2 low-flow yields for streams in vicinity of your point of interest range from about
0.58 to 0.75 cfsm (average 0.69 cfsm). The regional relations presented in the above-referenced report for
Hydrologic Area 10 indicate that a 30Q2 low-flow yield (using a drainage area 0.5 sgmi and mean annual
runoff)is between 0.85 and 0.9 cfsm.
Applying the range of above yields to the drainage area of your specific point of interest would..provide the)
'flow estimates in units of cubic feet per second (cfs)..A'qulok-n-dirty delineation of the basin upstream from
,your point of interest suggests the drainage area is approximately;0 2 sgmi Applying the above average)
(,yields results in 7Q10 and 3002 discharge estimates at 0,05 cfs and 0.14 cfs, respectively.)
However, the lack of a stream indicated on the topo map raises a concern in my mind that the estimates may
(� be too high. Even if this stream were described as being sustained by a spring,there's a need for site-

specific data to further resolve the low-flow estimates for this point of interest. Until then, it would be my
"..\, judgment based on current information that the 7Q 10 is more likely to be less than 0.05 cfs.
Please note the estimated discharges and regional relations presented in the report are based on data
ending during the late 1980's and do not reflect the occurrence of recent droughts, which have resulted in
decreased low-flow statistics at some USGS gaging stations.
Please understand this information is based on a preliminary assessment. Further analyses would be
needed to confirm the initial assessment, and a fee of$250 per site is required for completion of a more in-
depth assessment and formal determination of estimates. If you want us to complete a more in-depth
assessment, please let me know and we'll proceed from there. The assessment would be completed within
four weeks, and the response would be made via email with an invoice mailed separately via regular mail
following the provision of estimates.
Hope this information is helpful.

- Under General Permit NCG550000
for Single-Family Residence
939 Golf Course Road N.of Linville)
Avery County
Dear Mr.Crosland:
General Permit Coverage. In accordance with your application for discharge,the Division of
Water Quality(DWQ)herewith forwards the subject Certificate of Coverage(COC)to discharge under
the subject state-NPDES general permit.This permit is issued pursuant to the requirements of North
Carolina General Statue 143-215 .1 and the Memorandum of Agreement between North Carolina and the
US Environmental Protection agency dated October 15,2007(or as subsequently amended). Your permit
package includes:
r, A copy of the Certificate of Coverage for your treatment facility
• A copy of General Wastewater Discharge Permit NCG550000
o A copy of a Technical Bulletin for General Wastewater Discharge Permit NCG550000
• A copy of the approved drawings,signed January 18. 2013
• Engineer's Certification form(to be completed and rammed to DWQ).
DWQ understands from your authorized consultant,Lash Engineering Inc.,that there is no local city
sewer available,and that due to steep slopes and poor percolation estimates,site soils are unsuitable for a
conventional septic system. Therefore,the most viable alternative is onsite treatment and discharge to
surface waters of the State.Please note that this discharge must meet all surface water-quality standards,
and you must comply with DWQ's operation and maintenance requirements.Moreover,compliance
under this COC restricts discharge to 100%domestic flow,not to exceed 480 gallons per day for a four
(4)bedroom single-family residence(120 gpd/bedroom).
Operation and Maintenance. As Permittee you are responsible to maintain all components in the
approved treatment system, and will be held accountable to meet Surface Water-Quality Standards.
Compliance includes following manufacturer's guidelines,conducting and documenting inspections,
establishing sources for OEM spare parts and supplies,making necessary repairs,and documenting said
maintenance for the duration of the permit.
Upon DWQ's request,the Permittee must provide records and demonstrate efforts to maintain the
approved system.The Division recommends that the Permittee seek manufacture-certified training,or a
qualified contractor service to regularly inspect and maintain the treatment system.

This effluent discharges to surface waters classified for general use,and as trout waters(C;Trout).Please
note that if this classification changes,the Division may revisit this discharge and adjust according to the
stream's designated uses.
This COC is not transferable except after written notice to the Division of Water Quality.The Division
may modify,or revoke and reissue this COG This permit does not affect your legal responsibility to
obtain other permits required by the Division of Water Quality,the Division of Land Resources,the
Coastal Area Management Act,or any other Federal or local government.
If any parts,measurement frequencies or sampling requirements contained in this general permit are
unacceptable,you have the right to request an individual permit by submitting an individual permit
application.Unless such demand is made,this Certificate of Coverage(COC)shall be final and binding.
Authorization to Construct(ATC)Permit. According to the permit application, the existing
subsurface septic-system has beenjudged unsuitable for discharge by the Toe River Health District
(letter from Lee W.Clark,EHS,dated February 3, 1993).In accordance with the application and the
attached approved plans and specifications,DWQhereby authorizes installation of
• influent drain line;4-in diameter

NCG550000,and is subject to revocation unless wastewater treatment facilities are constructed in
accordance with the conditions and limitations specified in this General Permit. In the event that the
facilities fail to perform satisfactorily,including creating nuisance conditions,the Permittee shall take
immediate corrective action as may be required by this Division,such as the construction of additional or
replacement wastewater treatment(s)or disposal facilities.Failure to abide by the requirements of this A
to C permit may subject the Permittee to an enforcement action by the Division of Water Quality in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.
The Permittee or responsible Engineer shall notify DWQ's Raleigh Regional Office(919-791-4200)a
minimum of three(3)working days in advance of operating the installed facilities.This will serve to
provide DWQ an opportunity to inspect facilities as built. Such notification to the regional office
supervisor shall be made during normal office hours from 8:00 a.m.until 5:00 p.m.Monday through
Friday,excluding State holidays.
Upon completing construction and prior to operating this permitted facility,a North Carolina-

Project Summary for:
Crosland Residence at 939 Golf Course Road
Avery County; Linville, NC.
The project is located at 939 Golf Course Road in Linville, NC. in a subdivision on
the east side of Highway # 105 North of Linville, NC. The home proposed is a 4
bedroom residence located on a 0.76 acre lot. The Health Department has had
potential buyers interested in the property in the past and has made visits to the
property. Soil investigation has shown that the existing soils are incapable of
sustaining a typical septic system. Further analysis determined that an advanced
system with drip tubing could not be supported either. Therefore, the Health
Department has determined that the site cannot support an on -site disposal system.
A letter to that effect has been included in this application. Foothills Soils (Connie
Adams) has also determined that the existing soils would not support a disposal
system. Foothills Soils Consulting was not asked to make a report since it agreed
with the Health Department findings. The neighboring pieces of property are
developed into homes within the subdivision and adjacent to this property, making
additional acquisition of land for additional disposal very difficult. The online map
from the DWQ shows that there are several existing systems permitted within this
area of the subdivision. I cannot tell if they are direct discharge, only that they are
permitted through DWQ. That map (watershed determination) is also included
with this application.
A copy of the Health Department's findings is included in this application.
Because the Health Department has declined the site for disposal, a soil report was
not acquired. However, Connie with Foothills is prepared to write one if required.
A new system will be designed for 4 bedrooms at 480 gallons per day. The system
will utilize a 1,000 gallon septic tank and a new treatment facility will be added to
treat the wastewater to TS II standards with a UV light added for the removal of

pathogens. The system will also be installed with de -nitrification "bio-pack"
modules to reduce nitrogen output. The treatment facility will be down stream and
downhill of the proposed water well, which is over 100 feet away. A M-400
Septiech system designed for the 480 gallon system will be installed. The UV
light will be incorporated into the M-400 tank. The M-400 utilizes three sets of
pumps. One set is to remove the small amounts of dead bacteria (microbes) that
have been flushed through the media with the wastewater and have accumulated in
a reservoir on the tank bottom. They are then pumped back to the septic tank for
additional anaerobic digestion (denitrification). As such, sludge and flock do not
accumulate and the processor does not require pumping. This is called the "pump
back" pump. A Gould LSP03 is proposed. A second set is for recirculating the
effluent back through the media to get the TS II treatment levels. A Tsurumi OM2
pump is proposed. The third set is the effluent pumps which are used to pump the
effluent out once the treatment process is complete. The same pump as the pump
back is proposed (the Gould LSP03). This will make maintenance easier having
the same pump specified. These effluent pumps are more than adequate to pump
to the creek as the elevation change is very minor. I used a 10 foot head as a very
conservative number. The system is physically located 7' above the creek and 3'
above the road to assist in preventing any backup of the creek into the M-400 tank.
The creek would flow over the road and further down the hill prior to it backing up
into the effluent pipe of the system. A cleanout is also proposed at the exit of the
effluent pipe to assist with cleaning. The UV light is located on the discharge side
of the M-400 unit so treated effluent is passing through the light. The UV light is
the last stage the effluent passes prior to being discharged. The head losses of the
effluent passing through the UV light are very minor (negligible). I have included
these calculations.
The "Denite Package" will be installed with this unit. This SeptiTech nitrogen
reduction technology first nitrifies wastewater by the aerobic trickling filter
process. Nitrification of the ammonium (NH4) in the wastewater occurs in the
processor as it passes through the media. Nitrified wastewater is then passed into
an anoxic (<2 mg/1 dissolved oxygen) environment where a culture of anaerobic
bacteria satisfies their need for oxygen by chemically stripping the oxygen off
other compounds, such as NO3. To promote denitrification within the anoxic
environment, SeptiTech has developed zones of submerged media with the
required conditions of temperature, alkalinity, and BOD levels. Similar to the
aerobic process, the denitrification process is self-adjusting based on demand and
controlled by the PLC within the Control Panel to provide consistent results.

The system utilizes a Septitech Control Panel that has been designed to work for
this unit. It is a standard panel within a NEMA 4 enclosure setup for the floats,
pumps and internal monitoring of the system. A programmable micro -logic
controller (PLC) activates the recirculation and discharge pumps through a
program that self -adjusts these operations based on actual wastewater flow into the
processor (as monitored by the PLC). The processor constantly evaluates the water
usage and meters out the effluent discharge to the disposal area at the appropriate
interval to assure proper effluent treatment.
As part of the Control Panel, the unit will be provided with telemetry for off -site
monitoring of system performance. The Septitech M-400 is a State approved unit.
The State Certification (through DENR — not DWQ) for the tank has been included
with this submittal along with the NSF certification.
There is not a ground water issue where the tanks are located because of the slope
down to the creek. The units are approximately 7 feet higher than the creek at its
closest point and approximately 12 feet higher than the road. Should the creek
back up (due to a blocked culvert for instance), it would flow over the road prior to
flooding the area of the tanks. Therefore there is minimal if any upward pressure
from groundwater or flooding and as such no anti -floatation has been added to the
plans. There is no need.

This site is extremely small which makes all the setbacks difficult for adherence. The site is 104'
wide at the front and expands out (pie shaped) to 260' at the back. The lot is 185' deep from
front to back. We have worked with the Architect to place the residence in a location that makes
sense for the lot and allows maximum distance for setbacks. The 50' setback off the property
lines (including the R/W) was added to the plans. The water wells were located on the adjoining
lots and were added to the plan with 100' circular setbacks added. The remaining setbacks are
for the creeks. There is one main creek that runs through the middle of the property. This is the
creek that is to be used for disposal. It has a watershed of about 104 acres with springs feeding.
I have observed this creek during the winter and summer months and found it always flowing
well at all times. As you are looking at the lot from the front, there is a small drainage way to the
left with a small watershed. This creek is a dry weather creek, adds minimally to the total flow
at the road but is located far to the left more than 50' away from the proposed units. There is
another dry weather creek on the far right of the property (near the proposed water well). It has a
very small watershed of about 0.5 acres. The 50' setbacks are required off of "Surface Waters"
which I am assuming are the blue lines on an USGS map or lines located on the watershed
classification map on the DWQ website (I can't find a definitive definition). None of these lines
show up on either map and a copy of both maps are included in this submittal. However, a 25'
setback is being maintained, in addition the system is located approximately 10' higher than the
road so it is virtually impossible for the creeks to back up to even the bottom of the units. If the
culvert were to be blocked the flow of water from the creeks would flow over the road and never
back up into the property. The offset from the house is approximately 60'. The control panel is
located at the unit and is within a few feet of the driveway for easy maintenance and visibility.
If I can be of any further service, please do not hesitate to call.

The Process Science of the SeptiTech® System:
Summary
SeptiTech® uses an enhanced recirculating biological trickling filter system in a treatment process that is
optimized to remove a high percentage of BOD, TSS, and nitrogen from wastewater through aerobic and
anaerobic degradation. The SeptiTech processor is added to a conventional system between the septic
tank and final soil absorption system (typically a leach field).
Initially, raw wastewater passes through a baffled septic tank, sized according to state code, where a
portion of the solids and grease are separated out. Wastewater flows (typically via gravity) from the
septic tank into the reservoir of the processing tank beneath the trickling filter. The SeptiTech treatment
process uses unique characteristics of a patented filter media to construct a trickling filter in which. the
treatment occurs in the mixed -liquor as it passes though the filter. The filter consists of a bed of highly
permeable hydrophobic media situated over a reservoir into which the percolate drains. Within the
reservoir is a pump that distributes a combination of percolate and newly added wastewater fi•om the
baffled septic tank to the top of the media.
SeptiTech residential models use polystyrene hydrophobic bead filter media, which occupy the upper
portion of the treatment unit. Due to the hydrophobic nature of the media, microbes present in the
wastewater do not strongly attach to the media, but are rather entrained within the wastewater as it flows
through the media. In this suspended state, the microbes use and transform the nutrients and organic
materials provided by the constant supply of fresh wastewater to form new cell mass. The open spaces
within the media allow air to freely pass through, providing ample oxygen to support the microorganisms.
The percolate from the filtering process drains into the reservoir for further recirculation (approximately
70 times/day) or discharge. Several times per day, a portion of the wastewater in the reservoir is pumped
back to the septic tank where denitrification occurs. Nitrification of the ammonium in the wastewater
occurs in the liquor as it passes through the media.
The timing and sequence of the recirculation of wastewater in the lower collection reservoir, as well as
the recirculation of a portion of the waste back to the septic tank, is controlled by a programmable logic
controller (PLC). The PLC also controls the discharge to the leaching system. A more specific
description of the process is provided as follows:
How the Standard SeptiTech® System works:
Step 1 Wastewater is discharged from the home or business to a partitioned septic tank where
solids settle and begin to undergo anaerobic decomposition. The decanted effluent flows into the
SeptiTech processor tank for treatment.
Step 2 Wastewater from the septic tank enters the processor and collects in a reservoir at the base
of the tank where it mixes with treated water. Wastewater is pumped up to the treatment area
above the reservoir where outside air is passively drawn into the wastewater stream. Oxygenated
wastewater is uniformly sprayed over the media by low-pressure spray nozzles. The media
consists of polystyrene beads that provide a hydrophobic surface and an exceptionally high

treatment area to wastewater volume ratio. The microbes residing in the pore spaces of the filter
beads break down pollutants in the wastewater as it migrates downward through the media and
back into the reservoir below. The wastewater can be circulated through the filter media 70 or
more times in a 24-hour period by the recirculation pump.
A programmable micro -logic controller (PLC) activates the recirculation and discharge pumps
through a program that self adjusts these operations based on actual wastewater flow into the
processor (as monitored by the PLC). The processor constantly evaluates the water usage and
meters out the effluent discharge to the soil absorption system in equal doses over a 24-hour
period (a dosing schedule can be customized to the project specification).
SeptiTech processors are sized based on the projected design flow with additional capacity to
accommodate wastewater surges (morning and evening flows, special events, etc). Under surge
conditions, the PLC senses the increased flow into the system and adjusts the treatment process to
gradually accommodate the accumulated surge flow while maintaining treatment effectiveness. If
the PLC senses reduced flow, it will ratchet the system down, and after several days enter "sleep
mode" during which the processor only operates long enough to maintain the microbe culture.
SeptiTech processing starts automatically with any wastewater input. The recirculation system
then remains in operation, continuing to automatically reset as necessary, as long as wastewater is
discharged into the processor or until the entire accumulated surge flow has been discharged.
Microbes have a short life cycle, flourishing and dying within a few hours. Due to the unique
physical characteristics of SeptiTech's patented media, the wastewater and microbes do not wet
or strongly adhere to the media surfaces, thereby reducing the potential for the media clogging.
Instead of being stationary, the microbes migrate along with the wastewater increasing their
degradation effectiveness. Dead microbes are flushed through the media with the wastewater and
drain into the reservoir at the base of the processor tank. A "pump -back" system periodically
pumps them back to the septic tank for additional anaerobic digestion (denitrification). As such,
sludge and flock do not accumulate and the processor does not require pumping.
Step 3 After completing the prescribed treatment process in the processor, the treated water is
time dosed to the disposal field to insure small frequent dosing of the field and proper absorption
by the soil. In addition, pressurized delivery to the field allows placement of the disposal
trenches all in one area or in several mini -disposal areas on the same lot.
Step 4 Finally, SeptiTech disposal trenches lie nearer to the surface of the ground than in a
standard leach field to enable the action of soil microbes to further polish the effluent.
In addition to our standard biological trickling filter processor, SeptiTech systems can provide enhanced
pathogen destruction and can further reduce total nitrogen through the use of complimentary ultraviolet
(UV) sterilization and Denitrification processes, respectively.
UV Sterilization
Typical residential wastewater carries fecal coliform at a concentration of 10' to 109 colonies per 100
milliliters (col/100 ml) of wastewater'. Standard SeptiTech processors reduce this concentration to levels
ranging from less than 10 to 1,000 col/100 ml.
'Design Manual - Onsite Wastewater Treatment and Disposal Systems, Environmental Protection Agency, Washington, D.C. 1980.

However, in certain applications (e.g., close proximity to surface water, water supply wells, irrigation
disposal, etc.) a further reduction of bacteria and viruses may be desired. Due to the clarity of the
effluent from the SeptiTech processor, UV sterilization technology can be used to destroy the majority of
the pathogens remaining. This technology.is currently installed in over sixty SeptiTech systems in a
number of states including several coastal islands. Fecal coliform concentrations typically range from
non -detectable to 0,5-col/100 ml and average 0.1-col/100 mi. Actual concentrations depend on variations
in wastewater strength and clarity. To produce a more consistently low coliform concentration (less than
0.05 col/100 ml), SeptiTech has developed an enhanced UV process that is being used in several
commercial systems.
Denitrification
For critical resource areas that exhibit a high degree of sensitivity to the effects of nitrogen loading,
SeptiTech has developed a denitrification process to further enhance total nitrogen removal during
pretreatment. The SeptiTech denitrification systems have been proven. to remove a larger percentage of
total nitrogen by combining the nitrifying capabilities of our aerobic biological trickling filter system with
an enhanced denitrification procedure.
The SeptiTech nitrogen reduction technology first nitrifies wastewater by the SeptiTech aerobic trickling
filter process. Nitrification of the ammonium (NH4) in the wastewater occurs in the processor as it passes
through the media. Nitrified wastewater is then passed into an anoxic (>2 mg/1 dissolved oxygen)
environment where a culture of anaerobic bacteria satisfies their need for oxygen by chemically stripping
the oxygen off other compounds, such as NO3. To promote denitrification within the anoxic environment,
SeptiTech has developed zones of submerged media with the required conditions of temperature,
alkalinity, and BOD levels. Similar to the aerobic process, the denitrification process is self-adjusting
based on demand and controlled by the PLC to provide consistent results.
SeptiTech's nitrogen reduction technology has completed a full year of verification testing under the US
EPA Environmental Technologies Initiative, Source Water Protection Program. This testing was designed
to verify nutrient reduction of the SeptiTech treatment technology and was being conducted by the
Barnstable County Department of Health at the Massachusetts Septic System Test Center in Bourne.
During the testing, the SeptiTech system was loaded with influent wastewater from a sanitary sewer.
SeptiTech's nitrogen reduction capability was measured by constituents that demand oxygen for treatment
(BOD and CBOD), and nitrogen species (TKN, NH4, NO2, and NO3). Operational characteristics such as
labor to perform maintenance, maintenance tasks, durability of the hardware, noise and odor production
were also monitored. Effluent testing showed CBOD5 and TSS was 98% removed. Average Total
Nitrogen in effluent was 14 mg/1. A full report for this testing is posted on the EPA (www.epa.gov/etv)

NSF International (NSF) operates the Water Quality Protection Center (WQPC) under the U.S.
Environmental Protection Agency's Environmental Technology Verification (ETV) Program. The WQPC
evaluated the performance of a fixed film trickling filter biological treatment system for nitrogen removal
for residential applications. This verification statement provides a summary of the test results for the
SeptiTech® Model 400 System. The Barnstable County (Massachusetts) Department of Health and the
Environment (BCDHE) performed the verification testing.
The U.S. Environmental Protection Agency (EPA) created the ETV Program to facilitate deployment of
innovative or improved environmental technologies through performance verification and dissemination
of information. The goal of the ETV program is to further environmental protection by substantially
accelerating the acceptance and use of improved and more cost-effective technologies. ETV seeks to
achieve this goal by providing high quality, peer reviewed data on technology performance to those
involved in the design, distribution, permitting, purchase, and use of environmental technologies.
ETV works in partnership with recognized standards and testing organizations, stakeholder groups
consisting of buyers, vendor organizations, and permitters, and the full participation of individual
technology developers. The program evaluates the performance of innovative technologies by developing
test plans that are responsive to the needs of stakeholders, conducting field or laboratory tests (as
appropriate), collecting and analyzing data, and preparing peer reviewed reports. All evaluations are
conducted in accordance with rigorous quality assurance protocols to ensure that data of known and
verifiable quality are generated and that the results are defensible.

ABSTRACT
Verification testing of the SeptiTech® Model 400 System was conducted over a twelve month period at
the Massachusetts Alternative Septic System Test Center (MASSTC) located at Otis Air National Guard
Base in Bourne, Massachusetts. Sanitary sewerage from the base residential housing was used for the
testing. An eight -week startup period preceded the verification test to provide time for the development of
an acclimated biological growth in the SepfiTecl? System. The verification test included monthly
sampling of the influent and effluent wastewater, and five test sequences designed to test the unit
response to differing load conditions and power failure. The SeptiTech® System proved capable of
removing nitrogen from the wastewater. The influent total nitrogen (TN), as measured by TKN, averaged
39 mg/L, with a median of 39 mg/L. The effluent TN (TKN plus nitrite/nitrate) concentration averaged
14 mg/L over the verification period, with a median concentration of 14 mg/L, which included an average
TKN concentration of 6.8 mg/L and a median concentration of 5.7 mg/L. The system operating conditions
(pumps and float settings) were controlled by a programmable logic controller (PLC), which was adjusted
at the end of the startup period and then remained constant during the test. All mechanical equipment,
pumps, level switches, alarms, etc. operated properly throughout the test. There were two service calls
during the test. During the first call, eight months into the test, the system was cleaned and the PLC reset.
The second call for a high water alarm determined that the effluent pipe had collapsed due to an
installation problem not related to the system itself. After a lightning strike at the test site, the modem for
the PLC was replaced.
TECHNOLOGY DESCRIPTION
The following description of the SeptiTech System was provided by the vendor and does not represent
verified information.
The SeptiTech® System is a two stage treatment technology, based on a fixed film trickling filter, using a
patented highly permeable hydrophobic media. The first stage of treatment occurs in the primary tank (for
this test a 1,500 gallon two compartment septic tank, standard unit uses a 1,000 gallon tank) in which the
solids are settled and partially digested. The second stage of the SeptiTech® System, is a processor that
provides secondary wastewater treatment. Microorganisms present in the wastewater grow within the
media, using the nutrients and organic materials provided by the constant supply of flesh wastewater to
form new cell mass. Air is drawn into the system via an air intake pipe at the top of the SeptiTech System.
Venturis located in the sprinkler head distribution piping aerate the wastewater sprayed onto the media.
The system does not have a fan or compressor.
The SeptiTech® System is designed to remove total nitrogen from the wastewater by nitrification and
denitrification. Nitrification occurs in the second stage of the SeptiTech System, where ammonia nitrogen
is converted to nitrite and nitrate (predominately nitrate), while denitrification occurs in the
anaerobic/anoxic primary tank. According to SeptiTech, denitrification also occurs in the BioPack SF 30
Random Stack Media used in the system tested, which floats in the reservoir below the aerobic media.
The verification testing was performed using a full scale, commercially available unit, which was
received as a self-contained system ready for installation. Wastewater from the septic (primary) tank
flows by gravity to the Processor reservoir section, located below the filter media. There are four pumps
located in the reservoir. One pump recirculates wastewater from the reservoir to the top of the Processor,
where the wastewater is sprayed over the filter media. The second and third pumps are used to return
wastewater and solids from the reservoir back to the septic tank. The fourth pump is for the discharge of
treated wastewater to the disposal location. The SeptiTech® Model 400 System is supplied with a PLC,
which controls the frequency and duration of pump operation, as well as all alarm functions, data
collection, and communication packages.

VERIFICATION TESTING DESCRIPTION
Vest. Site
The MASSTC site is located at the Otis Air National Guard Base in Bourne, Massachusetts. The site uses
domestic wastewater from the base residential housing and sanitary wastewater from other military
buildings in testing. A chamber located in the main interceptor sewer to the base wastewater treatment
facility provides a location to obtain untreated wastewater. The raw wastewater, after passing through a
one -inch bar screen, is pumped to a dosing channel at the test site. This channel is equipped with four
recirculation pumps that are spaced along the channel length to, ensure mixing, such that the wastewater is
of similar quality at all locations along the channel. Wastewater is dosed to the test unit using a pump
submerged in the dosing channel. A prograrmnable logic controller (PLC) is used to control the pumps
and the dosing sequence or cycle.
Methods and Procedures
The SeptiTech® System was installed by a contractor, with assistance from the BCDHE support team, in
June 2001. The unit was installed according to installation instructions supplied by SeptiTech, Inc. On
June 14, 2001, the primary tank was filled with wastewater and the dosing sequence began. An eight -
week startup period allowed the biological community to become established and the operating conditions
to be monitored. The standard dosing sequence was used for the entire startup period.
The system was monitored during the startup period, including visual observation of the system, routine
calibration of the dosing system, and collection of influent and effluent samples. Three sets of samples
were collected for analysis. Influent samples were analyzed for pH, alkalinity, temperature, BOD5, TKN,
NH3, and TSS. Effluent samples were analyzed for pH, alkalinity, temperature, CBOD5, TKN, NH3, TSS,
dissolved oxygen, NO2 -, and NO3 _-
The verification test consisted of a twelve-month test period, incorporating five sequences with varying
stress conditions simulating real household conditions. The five stress sequences were performed at two -
month intervals, and included washday, working parent, low load, power/equipment failure, and vacation
test sequences. Monitoring for nitrogen reduction was accomplished by measurement of nitrogen species
(TKN, NH3, NO2, NO3). Biochemical oxygen demand (BOD5) and carbonaceous biochemical oxygen
demand (CBOD5) and other basic parameters (pH, alkalinity, TSS, temperature) were monitored to
provide information on overall system performance. Operational characteristics, such as electric use,
residuals generation, labor to perform maintenance, maintenance tasks, durability of the hardware, noise
and odor production, were also monitored.
The SeptiTech® Model 400 System has a design capacity of 440 gallons per day. The verification test was
designed to load the system at design capacity (:L 10 percent) for the entire twelve-month test, except
during the low load and vacation stress tests. The SeptiTech' System was dosed 15 times per day with
approximately 29-30 gallons of wastewater per dose. The unit received five doses in the morning, four
doses mid -day, and six doses in the evening. Dosing volume was controlled by adjusting the pump run
time for each cycle, based on twice weekly pump calibrations. Volume per dose and total daily volume
varied only slightly during the test period. The daily volume, averaged on a monthly basis, ranged from
432 to 449 gallons per day. This was within the range allowed in the protocol for the 440 gallons per day
design capacity.
The sampling schedule included collection of twenty-four hour flow weighted composite samples of the
influent and effluent wastewater once per month under normal operating conditions. Stress test periods

were sampled on a more intense basis with six to eight composite samples being collected during and
following each stress test period. Five consecutive days of sampling occurred in the twelfth month of the
verification test. All composite samples were collected using automatic samplers located at the dosing
channel (influent sample) and at the discharge of the unit. Grab samples were collected on each sampling
day to monitor the system pH, dissolved oxygen, and temperature.
All samples were cooled during sample collection, preserved, if appropriate, and transported to the
laboratory. All analyses were performed according to "Standard Methods for the Examination of Water
and Wastewater, " 19`" Edition, 1998. Washington, D.C. or other EPA approved methods. An established
quality assurance/quality control (QA/QC) program was used to monitor field sampling and laboratory
analytical procedures. QA/QC requirements included field duplicates, laboratory duplicates and spiked
samples, and appropriate equipment/instrumentation calibration procedures. Details on all analytical
methods and QA/QC procedures are provided in the full Verification Report.
PERFORMANCE VERIFICATION
Overview
Evaluation of the SeptiTech® Model 400 System at MASSTC began on June 14, 2001, when the system
pumps were activated, and the wastewater dosing started. Three samples of the influent and effluent were
collected during the startup period, which continued until August 13, 2001. Verification testing began at
that time and continued for twelve months, until August 12, 2002. During the verification test, 54 sets of
samples of the influent and effluent were collected to determine the system performance.
Startup
Overall, the unit started up with no difficulty. The installation instructions were easy to follow and
installation proceeded without difficulty. SeptiTech representatives setup the PLC, which controlled all
recirculation, recycle, and discharge pump tunes. No changes were made to the unit during the startup
period, and no special maintenance was required.
The SeptiTech® System removed CBOD5 and TSS after the first three weeks of operation, and continued
to improve over the next five weeks. At the end of the eight week startup, effluent CBOD5 was <2.0 mg/L
and TSS was 2 mg/L. The effluent TN concentration dropped from 24 mg/L after three weeks of
operation to 8.5 mg/L at the end of the startup period. Influent TN concentration ranged from 30 to 42
mg/L during this time. Both the nitrification and denitrification processes were established as shown by
the effluent TKN and nitrate concentrations of 2.3 mg/L and 6.0 ing/L, respectively. During the startup
period, ten percent of the treated wastewater was being recycled to the septic tank. Shortly after the end of
the startup, SeptiTech changed this recycle ratio to twenty percent by adjusting the pump rates in the
PLC. The discharge pump rate was also adjusted to account for daily dosing of the system at full design
flow. No other changes were made to the system.
Verification Best Results
The sampling program emphasizes sampling during and following the major stress periods. This results in
a large number of samples being clustered during five periods, with the remaining samples spread over
the remaining months (monthly sampling). Both average (mean) and median results are presented, as the
median values compared to average values can help in analyzing the impacts of the stress periods. In the
case of the SeptiTech® System results, the median concentrations for ammonia nitrogen are somewhat
lower than the average concentrations due to reduced nitrification efficiency from February through May,
which impacted the twelve month average concentration.
The TSS and BOD5/CBOD5 results for the verification test, including all stress test periods, are shown in
Table 1. The influent wastewater had an average BOD5 of 250 mg/L and a median BOD5 of 240 mg/L.

The TSS in the influent averaged 150 mg/L and had a median concentration of 140 mg/L. The effluent
showed an average CBOD5 of 5.4 mg/L with a median CBOD5 of 4.7 mg/L. The average TSS in the
effluent was 3 mg/L and the median TSS was 2 ing/L. CBOD5 concentrations in the effluent typically
ranged from 1 to 10 mg/L, and TSS ranged from 1 to 10 mg/L, except for two sampling days during the
twelve month verification test.

The nitrogen results for the verification test, including all stress test periods, are shown in Table 2. The
influent wastewater had an average TKN concentration of 39 mg/L, with a median value of 39 mg/L, and
an average ammonia nitrogen concentration of 24 mg/L, with a median of 24 mg/L. The average TN
concentration in the influent was 39 mg/L (median of 39 mg/L), based on the assumption that the nitrite
and nitrate concentrations in the influent were negligible. The effluent had an average TKN concentration
of 6.8 mg/L and a median concentration of 5.7 mg/L. The average NH3 N concentration in the effluent
was 5.1 mg/L and the median value was 2.4 mg/L. The nitrite concentration in the effluent averaged 0.32
mg/L. Effluent nitrate concentrations averaged 6.7 mg/L with a median of 7.0 mg/L. Total nitrogen was
determined by adding the daily concentrations of the TKN (organic plus ammonia nitrogen), nitrite, and
nitrate. Average TN in the effluent was 14 mg/L (median 14 mg/L) for the twelve month verification
period. The SeptiTech® System averaged a 64 percent reduction of TN for the entire test, with a median
removal of 64 percent.

Verification Test Discussion
By the end of the eight -week startup period and start of the verification test, the system was operating
with an acclimated biomass for both nitrification and denitrification. From August to December, the TN
reduction was typically in the 61 to 78 percent range with TN effluent concentrations of 8 to 11 mg/L.
The washday stress test performed in Utober 2001 did not appear to have an impact on nitrogen
reduction. Likewise, in December 2001, the working parent stress test was performed and the

performance of the unit remained steady during and following the stress period. In January and early
February, the normal monthly samples showed a decrease in nitrification efficiency as measured by
increases in TKN and ammonia in the effluent, to 18 mg/L and 14 mg/L respectively. TN in the effluent
increased to 20 mg/L in early February, during a period that corresponded to lower wastewater
temperatures and outside air temperatures.
The low load stress test was started on February 18 and was completed on March 10, 2002. During the
months of February and March, which included the stress test, the TN concentration varied from 7.5 to 17
mg/L. Nitrification was still occurring, but at lower efficiency than during the previous five months. This
also corresponded with the time flame with low effluent temperatures. At the end of the stress test, the
system was still reducing TN concentrations. It does not appear that the low load stress test had a direct
impact on the system, as the reduced nitrification efficiency started in the four weeks prior to the stress
test. The post stress test period from mid -March through May showed consistent results with TN
concentrations in the 15 to 18 mg/L range, except for one day at 27 mg/L. The power/equipment stress
test was performed from May 6 to 8, 2002, with no apparent change in the effluent quality in the post
stress test monitoring period.
A major change in performance occurred in late May or early June. The June 5 sampling showed TN
concentrations reduced to 10 mg/L, and both TKN and ammonia concentration in the effluent decreased
as well (6.0 mg/L and 3.7 mg/L, respectively). The nitrification process had improved and was reducing
the ammonia concentrations to levels similar to the first five months of the test. As the TKN and ammonia
levels decreased, the nitrate levels began to increase in the effluent, indicating that while the
denitrification process was removing some nitrate, it was not removing the increased concentration
produced by the improvement in nitrification.
The vacation stress test started on July 8 and continued through July 16, 2002. During this stress test,
there was no wastewater dosed to the system. The TKN and ammonia levels remained low in the post
stress monitoring period but the nitrate levels increased from 9 to 15 mg/L. During this period nitrate was
the main contributor to the effluent TN concentration, which ranged from 16 to 24 mg/L. It is not clear if
the vacation stress test had a direct impact on the denitrification process, as the increasing nitrate levels
began to occur when the nitrification process unproved prior to the start of the vacation test. It is possible
that the nitrate levels would have been higher, even if the stress test was not performed. However, the
lack of flow during the vacation stress test reduced the amount of recycle flow from the SeptiTech
reservoir to the septic tank. Therefore, there was less nitrified wastewater being recycled, which may have
impacted the response time for the denitrifying organisms.
The system performance remained consistent for the duration of the verification test. The TKN and
ammonia nitrogen effluent concentrations were consistently low and similar to the fast five months of the
verification test. The nitrate levels remained in the 13 to 15 mg/L range and the TN concentration in the
effluent ranged from 14 to 20 mg/L. Alkalinity concentration in the effluent remained lower at 50 mg/L.
It is not clear why the denitrification efficiency was lower throughout the July and August period as
compared to the previous August through December period.
Over the twelve-month test, the system did exhibit some instability in the individual nitrogen removal
mechanisms, i.e. the nitrification and denitrification processes, particularly during December 2001 to July
2002. These changes could be due to stressors not apparent from the data. Despite these changes, the
process continued to remove TN, providing an overall stable effluent quality for TN. The verification test
provided a sufficiently long test period to collect data that included both a long run of steady performance
by the SeptiTech® System and a period of reduced nitrification and denitrification efficiencies. During the
five months following startup, the TN removal was in the 60 to 80 percent range, with effluent
concentrations typically in the 8 to 11 mg/L range. The SeptiTech System continued to remove TN in the
02/04AVQPC-SWP The accompanying notice is an integral part of this verification statement. April 2003

later periods, even though the nitrification or denitrification processes were not operating as efficiently.
During the last six months of the verification test, the TN removal was in the 32 to 82 percent range, with
most results in the 50 to 60 percent range. Effluent TN concentrations ranged from 10 to 27 mg/L, with
most concentrations in the 15 to 20 mg/L range. The net effect of the lower performance in these later
periods increases the average effluent TN concentration for the verification test to 14 mg/L.
Operation and Maintenance Results
Noise levels associated with mechanical equipment were measured once during the verification period
using a decibel meter. Measurements were made one meter from the unit, and one and a half meters above
the ground, at 90' intervals in four (4) directions. The average decibel level was 60.0, with a minimum of
58.9 and maximum of 61.5. The background level was 37.7 decibels.
Odor observations were made monthly for the last eight months of the verification test. The observations
were qualitative based on odor strength (intensity) and type (attribute). Observations were made during
periods of low wind velocity (<10 knots), at a distance of three feet from the treatment unit, and recorded
at 90' intervals in four directions. There were no discernible odors during any of the observation periods.
Electrical use was monitored by a dedicated electric meter serving the SeptiTech® System. The average
electrical use was 8.4 kW/day. The electrical use included a heater for the PLC, which was located
outside at the test site. In nonnal applications, the PLC is placed in the home and an auxiliary heater is not
needed. The SeptiTech® System does not require or use any chemical addition as part of the normal
operation of the unit.
During the test, no mechanical problems were encountered with the operation of the system. The system
was cleaned after eight months by spraying water over the nozzles and media. This cleaning was
performed when a service call was placed to SeptiTech in April 2002, based on site operators observing a
lack of sound coining from the unit. During the service call, no problems were found with the unit. The
PLC was reset and the system continued in operation. In June 2002, a high water alarm sounded and a call
was placed for service. SeptiTech responded the next day and found the discharge pipe had collapsed. In
addition, lightning had struck the test site, damaging the modem and causing the PLC to enter a "safe"
mode. The discharge pipe was repaired, a new modem installed, and the PLC reset. The discharge pipe
failure was apparently due to improper soil preparation and was not related to the system itself. No
changes or adjustments were needed to the float switches or pumps after the initial changes following the
startup period.
The treatment unit appeared to be of durable design and also proved to be durable during the test. The
polyethylene piping used in the system meets the needs of the application. Pump and level switch life is
always difficult to estimate, but the equipment used is made for wastewater applications. The only trouble
with the PLC was when lightning hit the site, at which time the modem was replaced to reestablish remote
communications.
Quality Assurance/Quality Control
NSF International completed QA audits of the MASSTC and BCDHE laboratory during testing. NSF
personnel completed a technical systems audit to assure the testing was in compliance with the test plan, a
performance evaluation audit to assure that the measurement systems employed by MASSTC and the
BCDHE laboratory were adequate to produce reliable data, and a data quality audit of at least 10 percent
of the test data to assure that the reported data represented the data generated during the testing. In
addition to quality assurance audits performed by NSF International, EPA QA personnel conducted a
quality systems audit of NSF International's QA Management Program, and accompanied NSF during
audits of the MASSTC and BCDHE facilities.

UV lights of a low flow nature are typically a low pressure type, short wave, mercury vapor discharge
tube that produces ultraviolet wavelengths lethal to microorganisms. The low pressure allows the
units to run with less power and thereby generating less heat for longer life of the bulbs. The Emperor
Aquatics UV "High Output" Light has been specified for this project.
The spectrum of UV light that is lethal is called UV-C. This includes a wavelength range within 240-
280 mu. A wavelength around 254 to 264 is considered ideal. This lamp is set to 254 mn.
Different microorganisms are extinguished at different doses. The larger "pests" take longer. Fecal
Coliforms are extinguished at near 6600 µWs/cm. This lamp has a range up to 30,000 µWs/cm.
Although there is a wide spectrum of bacteria, viruses and protozoa, most of the "pests" are
extinguished between 2,000 and 20,000. Having a range up to 30,000 µWs/cm, assures that the
germicidal action is most effective across this wide range. For this application, fecal coliforms are
most important, which have a dose requirement of about 6600 µWs/cm. This is well within range.
The glass plays an important function in the effectiveness of the lamp in that the glass can absorb the
UV-C wavelength. The hard quartz glass is most effective and is utilized in the "high output" unit.
An additional coating "L" is added to the glass that adds resistance to "solarization" so that the bulb
remains highly effective for longer periods.
The Emperor Smart HQ UV Light has been submitted for review because of its ability to be installed
in the vertical position. It clearly has the UV qualifications to be effective. The requirements for
vertical placement are spelled out in the installation guidelines with a warning to insure the power
head is above the water line. The power unit cannot be submerged. This note has been added to the
plans. This unit is acceptable for use in this application and is accepted for use on this project.
Sincerely,
Michael Lash, PE.

System Description
SeptiTech has made a recent change in the preferred manufacturer of ultraviolet (UV)
disinfection system for use in systems that require disinfection prior to discharge. The
reason for the recent change is that the manufacturer of the LTV unit previously used
(Siemens Sunlight Systems UV) has been discontinued by the manufacturer and is no
longer available.
Therefore, SeptiTech has chose to use the Emperor Aquatics Smart High Output LTV
Sterilizer model 025050/50. This unit is rated at the following specifications:
Water Flow Rate: 1,560 —1,980 gph (26 — 33 gpm)
Ouput: 30,000 µWs/cm2
Operating pressure: 20 psi
Voltage: 120 VAC @ 6014z
No. Lamps / Watts: 1 lamp @ 50 watts
The ITV unit is rated for 26-33 gpm at 20 psi operating pressure. SeptiTech will provide
a flow restr-ictor and pressure regulator on the discharge of the pump in order to ensure
that the operating parameters and not exceeded during operation.
A technical cut sheet, installation guide and operation and maintenance manual from the
manufacturer have been provided as part of this memo.
Control and Alarm
The operation of the UV unit is the same as it was previously for the Siemens Sunlight
Systems product. The control panel is outfitted to provide power to the LTV unit along
with a current sensor. Power to the UV unit is on all the time as long as power to the
control panel is provided. The current sensor is used to detect that current is being drawn
from the UV bulb. If the bulb was to fail to operate, current would no longer flow to the
bulb, and an alarm would be triggered at the control panel as the current sensor would no
longer detect current flow.

Frictional Losses
Frictional losses through the UV unit are minimal since the UV chamber is larger than
the discharge piping used with the discharge assembly. The UV unit has 2-inch inlets
and a 5-inch chamber. Based on calculations using factors from Cameron Hydraulic Data
handbook, the total frictional head loss assuming a flow rate of 30 gpm is 0.00856 ft
(assumed to be negligible). Head loss calculations are attached.

SMART UV...The Professional's Choicel
More animal husbandry and aquatic professionals choose SMART UVs over
competing UV brands because of our substantiated performance information,
effective product design and overall quality. With over thirty models to choose
from, Emperor Aquatics, Inc. has the right SMART UV to fit your application.
Size — Our SMART UV design always considers the lamp's UV C output and
length, while most competitors ignore these critical performance factors. This
explains why, in most cases, our equipment is physically larger.
Advantages:
Models shown with °I
optional mounting damps
�amll AUS1eeit11ev
Lamp Position — Our lamps are always positioned entirely between the inlet and
outlet water ports, utilizing the lamp's full arc length to its maximum potential.
Lamp Life — Long -Lasting GPH/T5 (Low-Pressure/Standard-Output) & T5 (Low
Pressure/High-Output) UV lamps offer 9,000 hours of continual operation equals
>80% efficiency at end of lamp life. These lamps use a specially coated "L" type hard
quartz glass that extends the life of the lamp while preventing the build-up of nitrogen
by-products (scaling) on the lamp's outer surface (Scaling diminishes UV C transmit-
tance). These nitrogen by-products are a problem commonly associated with ozone
producing WH" type glass UV lamps.
Water Flow Rates — SMART UV flow rates represent the equipment's true capacity,
which considers the lamp's UV-C output, lamp length, exposure chamber's inside
diameter, and UV transmissibility for specified UV dosages as per our specification
charts.

Subject: Low -flow characteristics for unnamed tributary to Linville River in Avery County... Re: Google Earth
Placemark:-GE3B.kmz
Ms. Adams,
In response to your inquiry about the 7Q10 and 30Q2 low -flow characteristics for an unnamed tributary to the
Linville River in Avery County, the following information is provided:
A check of the low -flow files here at the USGS North Carolina Water Science Center does not indicate a
previous determination for your specific point of interest on the unnamed tributary to the Linville River. The
files do indicate previous determinations at two nearby locations on the same unnamed tributary completed
in 1982. The 7Q10 discharges were estimated at less than 0.05 cfs, and the 30Q2 discharges were
estimated at approximately 0.1 cfs.
Inspection of the topographical quad map does not indicate the presence of a stream but rather a dry
channel coming from the ridge line at Grandfather Mountain.
In the absence of discharge records sufficient for a low -flow analysis, estimates of low -flow discharges are
determined by assessing a range of low -flow yields (expressed as flow per square mile drainage area, of
cfsm) at nearby locations where low -flow discharges have been determined.
A preliminary assessment of available information at five nearby USGS partial -record sites where low -flow
discharges were published in a statewide low -flow report for North Carolina (Giese and Mason, 1993;
available online at
http://Pubs.er.usgs.gov/#search:advance/pacie=l-/page size=100/series-cd=WSP/reportnumber=2403:0)
indicates that 7Q10 low -flow yields for streams in vicinity of your point of interest range from about 0.22 to
0.40 cfsm {average 0.3 cfsm . The regional relations presented in the above -referenced report for
Hydrologic Area 10 indicate that a 7Q10 low -flow yield (using a drainage area 0.5 sgmi and mean annual
runoff 2.5 cfsm) is between 0.35 and 0.4 cfsm.
In a similar manner, the 30Q2 low -flow yields for streams in vicinity of your point of interest range from about
0.56 to 0.75 cfsm (average 0.69 cfsm). The regional relations presented in the above -referenced report for
Hydrologic Area 10 indicate that a 30Q2 low -flow yield (using a drainage area 0.5 sgmi and mean annual
runoff is between 0.85 and 0.9 cfsm. .
However, the lack of a stream indicated on the topo map raises a concern in my mind that the estimates may
be too high. Even if this stream were described as being sustained by a spring, there's a need for site-

specific data to further resolve the low -flow estimates for this point of interest. Until then, it would be my
judgment based on current information that the 7Q10 is more likely to be less than 0.05 cfs.
Please note the estimated discharges and regional relations presented in the report are based on data
ending during the late 1980's and do not reflect the occurrence of recent droughts, which have resulted in
decreased low -flow statistics at some USGS gaging stations.
Please understand this information is based on a preliminary assessment. Further analyses would be
needed to confirm the initial assessment, and a fee of $250 per site is required for completion of a more in-
depth assessment and formal determination of estimates. If you want us to complete a more in-depth
assessment, please let me know and we'll proceed from there. The assessment would be completed within
four weeks, and the response would be made via email with an invoice mailed separately via regular mail
following the provision of estimates.
Hope this information is helpful.
