Subject: NPDES Permit NCG510000 renewal
Certificate of Coverage (CoC) NCG510362
Marble Maintenance Facility
Cherokee County
The facility listed above is covered under NPDES permit NCG510000 for discharge of remediated
groundwater. NCG510000 expires on September 30, 2006. Federal (40 CFR 122.41) and North Carolina (15A
NCAC 2H.0105(e)) regulations require that permit renewal applications must be filed at least 180 days prior
to expiration of the current permit. If you have already mailed your renewal request, you may
disregard this notice.
To satisfy this requirement, the Division must receive your renewal request postmarked no later than
April 3, 2006. Failure to request renewal by this date may result in a civil assessment of at least $500.00.
Larger penalties may be assessed depending upon the delinquency of the request.
If any discharge from the remediation system will occur after September 30, 2006, your CoC must be
renewed. Discharge of wastewater without a valid permit would violate North Carolina General Statute 143-
215.1; unpermitted discharges of wastewater may be assessed civil penalties of up to $25,000 per day.
If you have halted remediation activity due to lack of trust fund money, but your site ranking from the
Aquifer Protection Section requires future remediation & discharge, your CoC must be renewed.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions], contact me at the telephone number or e-mail address listed below.

Your facility is currently covered for wastewater discharge under General Permit NCG510000. This permit expires
on September 30, 2001. We are currently in the process of rewriting this permit and are scheduled to have the
permit reissued by the summer of 2001. Once the permit is reissued your facility would be eligible for continued
coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a general permit coverage renewal application
form. This will serve as your application for renewal of your permit coverage. The application must be
completed and returned with the required information by February 28, 2001 in order to assure continued coverage
under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
If the subject groundwater remediation project has been terminated, please complete the enclosed rescission
request form. Mailing instructions are listed on the bottom of the form. You will be notified when the rescission
process has been completed.
If you have any questions regarding the permit coverage renewal procedures please contact the Asheville Regional

Dear Mr. Myhra:
On behalf of the North Carolina Department of Transportation (NCDOT), S&ME, Inc.
submits the additional information requested for the referenced NPDES permit application.
Attached, please find a revised Notice of Intent (signed by a representative of the NCDOT)
to address your first, second and fifth comments. In addition, please find a copy of the
Corrective Action Plan (CAP) prepared for the referenced facility to address your third and
fourth comments. Sections 5.0, 6.0, and 7.0 of the CAP address the remediation system.
Although you are correct in stating that iron and manganese found naturally- in the
groundwater could impair the treatment system, we have not seen this phenomenon in
several treatment systems in the same region as the referenced facility and we do not
anticipate iron or manganese to interfere with the effluent water quality.
In response to your request that we review that air/water ratio for the air stripper, we
request that the Division accepts an air/water ratio of 100:1 for the proposed system
based on the system performance sheet found in Appendix B. Our design calculations
S&ME, Inc. 155 Tradd Street, Spartanburg, South Carolina 29301, [phone], Fox [phone]

�Y.- Paper

for the air stripper were based on influent concentrations from the analytical results from
the July 9, 1996 sampling event and on the effluent concentrations as defined by the
NCDEHNR's groundwater quality standards. As shown on the system performance
sheet, groundwater quality standards can be met with an air stripper that has an air/water
ratio of 100:1.
An additional $150.00 for an authorization to construct permit will be submitted after
approval to discharge to Puett Creek is granted.
Should you need additional information, please contact us at [phone].

Dear Mr. Frady:
For the following reasons, and in accordance ,r i.?; the Division policy, we must hereby return the
attached application and associated material recei\ed on September I3,1996:
• Notice of Intent (NOI) form is not signed by responsible party.
• The Permittee is required to submit process flow diagrams that are signed and sealed by
a North Carolina professional engineer to detail the treatment system operation.
• The Permittee is required to submit a site plan of the facility detailing the location of all
buildings, all monitoring wells. all recovery wells, and "the treatment system location in
reference to the discharge point.
• - All specs and design calculations must be signed and sealed by a North Carolina
professional engineer.
114c, text Was inc'Au d in reference :o the --olids and free product di-sposal method. The Division recommends that the subject facility consider implementing a filtration system as pan
of the remediation process to filter out naturally occurring iron and manganese in the groundwater.
These groundwater constituents often blind carbon systems and impair treatment efficiency. The
Division also recommends that the subject facility review the air/water ration for the air stripper
unit. The Division policy requires at a minimum an air/water ration of 120:1. Our calculations
show an air/water ration of 100:1 for the proposed treatment system.
Also, Please be advised that the Division must receive an additional S150.00 prior to processing an
authorization to construct permit.

OPERATIONCHNICAL
INFO V,,
Subgard Liquid Level Controls are designed to control the
overpumping of wells by the best possible method — locating the
entire control devise at the precise point that a constant liquid level
is to be maintained.
When the pumping level reaches the
Point at which the Subgard is installed, a Float
j level sensing member (float) senses the
lowering liquid level
When the float'is at its highest level
(fig. 1) all water from the pump goes to
the surface. As the float moves lower
with the water level, and reaches a
certain point, the linkage prey down Valve
the stem to the by-pass valve and opens
it slightly. This allows some of the water
t.
Float is at its highest level.
_ INSTALLATION 'Pass vane is closed.
A Subgard installed in a well that has extremek lok tie!4
conditions should be located a sufficient distance above the
Pump — such as 24 feet — to provide adequate water coaerae over the pump. Inadequate water coverage over the pump. when
most or all of the water being pumped is recirculated b� th?
Subgard, could result in an undersirable rise in the lean -
Temperature.
For this reason it is not recommended that a Subgard
be installed in a well with less than th GPM (gallons per
minute) well yield.
Always install check valve on discharge of Su ar
ri
coming from the pump to be diverted back into the well.
The by-pass valve returns to the well the
exact proportion of water the pump produces
beyond the well yield. The float and linkage
assembly, combined with the by-pass valve act
as a perfectly balanced unit to maintain the
licuid !evel regardless of the well yield and the
ac,,,a: cell yield is delivered to the surface.
11 the well yield continues to decline I'"'"
the float drops further and the valve all ws
more water to be recirculated. Eventually a
stability point is reached and the float stays at
that level until the well yield changes. N""
When the pumping level of the well is /
above the Subgard. full pumpca aciry 2r
Passes through the unit unrestricte/; P t
When the well level increases the Subgard Float is at its lowtst Itvc
automatically closes the recirculation � ah a and 8s vaa ��� i. /�S,
MATERIALS
Materials used in the construction of all Subgards include
only bronze, stainless steel and PVC. These are all resistant to
various types of corrosion commonly encountered in wells.

MODELS
Subgard units are made in various models lot use in well depths of
"j 1000 feet (300 meters). The recommended maximum
J pump capacity
to be used with each size unit is as follows:
Size GPM L/Sec.
1" 21 1.3
11N" 21 1.3
2" 40 2.6
2'iz•- 81 5.2
3" 101 6.1
4" 121 7.4
If a higher capacity is needed. additional Subgards are necessarv.
Subgard models vary in length and diameter, depending upon the
depth selling and riser pipe size.
Subgard by-pass or recirculation capacities at various depth
1 settings are shown below. The capacity of the Subgard at any given
setting must equal or exceed the pump capacity. If not, the pump
may produce more Water than the Subgard can recirculate and there
would be a chance of overpumping if the well yield is extremely low.
SIMPLE SIZING OF SUBGARD
Simple Subgard selection is determined by the amount of water to
be recirculated (use rated pump capacity for full protection) at the
Total Dynamic Head. Total Dynamic Head is determined as follows:
A) The Sub9ard setting.
8) The friction through the entire piping system"
C) The above ground system head or PSI ( mean pressure switch
setting.
Example: You have a 10 GPM submersible pump and 1" or 1'h'•
l drop pipe and would like complete pump protection.
a) Subgard setting ...................................... 240 feet
b) System friction losses .................................. 15 feet
c) Mean pressure switch selling 40 PSI x 2.31 h/PSI .92 leer
TOTAL DYNAMIC HEAD ............................. 347 feet
From the Subgard recirculation chart below or your Slide Chart, you
Will select a 1" or 1 %"Model 400.
RECIRCULATION CAPACITY
Subgard's recirculating capacity at various Total
Dynamic Heads is shown in the table at right.
• Note that this is the maximum amount of water
that will be recirculated to the well at various
system heads. Your pump capacity should not
exceed the Subgard capacity at the Total
Dynamic Head for full protection.

SHALLOWTRAY PROCESS
The Treatment
Process
The purpose of air stripping is to treat contaminated groundwater for the remov;
of certain volatile organic chemicals (VOC). The ShallowTray low profile air
stripper is a compact, low -maintenance solution to groundwater treatment.
The active components of a ShallowTray low profile air stripper are patent -
protected baffled sieve tray type aeration trays (The ShallowTray process is
protected under U.S. Patent #5,045215; Other U.S. and international patents
pending). Air is blown up through hundreds of 3J16' diameter holes in the
aeration tray. The air forms a froth of bubbles approximately six inches deep on
the aeration tray, generating a large mass transfer surface area where the
contaminants are volatilized. The necessary contact or residence time to reach
required volatilization is achieved through model size, addition of trays, and flow
rate selection.
Typically constructed of type 304L corrosion resistant stainless steel, or pofyeth:-
yiene, the tray unit utilizes counter current air and water flow through an array cf
baffled aeration trays. Sizing and design of a ShallowTray low profile air stripper
are determined by a variety of factors that include water flow rate, contaminar.t
concentration, temperature, required removal efficiency, and the physical -
chemical properties of the contaminants that govern their solubility in water.

BASIC SYSTEM
r ShallowTray systems are fabricated from rugged 304L stainless steel or molded
polyethylene. Each system is pre -assembled and factory tested before shipment
to your site.
Basic System
Components
Information from manufacturers of the components on your system are included
in the Components Information Section at the back of this manual
Air Pressure Gage
The pressure gage reads the pressure drop of the system in inches of water
column. The gage is connected to the system via an air hose that is attached to a
Pressure port on the sump tank. This air hose is connected to the 'high' pressure
port on the gage. The Sow' Pressure port is open to the atmosphere.
At initial start-up the pressure gage can be used to make adjustments to the
damper, located on the blower inlet. Adjustments should be made according to
the table:
Lof trams Minimum Press f.p
1 tray system 48 we
2 tray system T we
3 tray Sys 11' we
4 tray system 15' we
As stated below in the Damper section, beware when making damper adjust -
meats after initial start-up. Fouling may occur in the system which would affect
the air flow rate. A system that was fouled would produce a lower airflow at the
same pressure reading than the system did at initial start up. A system that was
severely fouled might not produce the minimum air flow requirements that the
system needs. If the pressure reading rises at a steady rate over a period of time,
and there have been no changes in the damper location and water flow rate,
chances are the system is fouling. If this occurs shutdown the system. Remove
the inspection ports and visualty inspect for signs of fouling. Occasionally inspect
the air hose for water build up, Water trapped in the air hose could produce an
erroneous reading. A shut-off valve is now provided on the pressure port. The
valve should be dosed when no one is at the site. This WIT help prevent conden-
sation building up inside the pressure gage. Condensation build up will ruin the
pressure gage.
Blower
The blowers on the ShalfowTray low profile air stripper units are typically cast
aluminum type B spark resistant, direct drive @ 3450 rpm, with motor options of
TEFL or EXP. Each blower is selected by our engineering staff to exceed the
minimum air flow requirements (cfm) at the nominal working pressure (inches of
water column) of each system.

.. .. l ...
It is critical that the blower damper be opened wide enough to provide the unit
with the designated minimum flow.
It is also critical that water does not enter the blower housing while the blower is
in operation; this will damage your blower and void the warranty. The high water
level alarm switch prevents ft from happening. Make sure it is installed property.
A small 3/80 drain hole is drilled on the bottom side of the blower housing to
provide a means of discharging any water that might splash in when the blower
is not in operation. When starting the unit for the first time, check that the blower
wheel is rotating in the direction of the arrow on the blower housing. If you hear
the blower wheel rubbing or any odd
sounds shut down the system immediately
and call North East Environmental Products.
Damper
There is a damper on the intake side of the blower. The damper is used to make
adjustments to the air flow rate (cubic feet per minute) of your system. The air
flow rate is increased (higher cfm's) by opening the damper wider.
Since the blower is pre -selected to exceed the minimum air flow requirements of
your system, you can adjust your damper, at initial start-up, using the pressure
reading on the pressure gage.
Follow the table below and adjust your damper to obtain the given value on your
pressure gage.
# o� Minimum Pressure
1 tray system 40 we
2 tray system T we
3 tray system 11 • we
4 tray system 15• we
Beware when mating damper adjustments after initial start-up. Fouling may
occur in the system which woad effect the air flow rate. A system that has fouled
would produce a lower air flow rate at the same pressure reading than the
system did at initial start up. A system that was severely fouled might not
produce the minimum air flow requirements that the system needs. For this
reason it is recommended that an air flow meter and an air pressure gage both
r
be used when adjusting the damper after initial start-up. It is also recommended
that you keep a log book of pressure readings so you can determine when the
system is fouling.
Demister
A wire mesh demisting pad is installed beneath the air exhaust nozzle located on
the top cover of the unii The purpose of the demisting pad is to remove water
droplets that would have blown through the vent line. It is possible, though unlike-
ly, that the demisting pad may become plugged or fouled. If this occurs the
demisting pad is easily removed. Disconnect the vent Fine, take off the top cover,
and remove the retaining screws on the bottom side of the cover. The demisting
pad can be cleaned with a pressure washer or replaced with a new one.

BASIC SYSTEM
Gasket
A black nitdle sponge gasket, of firm density, is used to form an airtight seal
around the sump tank and aeration trays. If there are any problems with the
gaskets contact North East Environmental Products as soon as possible. A
replacement gasket can be glued to the sealing flange using an industrial
neoprene contact adhesive, we recommend using Rubatex adhesive # R-27780.
Please contact North East Environmental Products. prior to making any gasket
repairs or adjustments.
Sight Tube
The sight tube provides a means of easily viewing the water level in the sump
tank. Make sure the valve to the sight tube is open.
Spray Nozzle
A spray nozzle is installed in all units except ones with gravity feed. The nozzle
directs the contaminated watertD the inlet chamber and begins the volatilization
process. The nozzle is rated for 15 psi at the systems ma)dmum water flow rate.
It is recommended that a strainer be installed somewhere in the inlet process
water line, especially at initial start-up to prevent sediment from plugging
the nozzle.
If the nozzle becomes plugged, A is easily removed by first remcving the top
cover and then unscrewing the r:.3zzle from the inlet piping. Clean it Y.+,h a wire
brush or a pipe cleaner. If the nczzfe causes too much back pressure or
becomes plugged too often, it can be removed without any serious effects to the
system's performance. Units that have a gravity feed system should not use a
spray nozzle. It causes too much back pressure. In these cases the inlet piping
should extend below the water level of the inlet chamber to provide an air lack.

SR II� Water Meters
%— (DN 15mm) through
1 " (DN 25mm) Sizes
SR lit Water Meters offer practically anything
you could want and expect in a meter, and more.
They're quality -engineered and quality -built ...
assunng you of durability and high measurement
accuracy. SR II Water Meters provide a host of
features and options for a variety of residential
metering applications or similar service needs.
These oscillating piston -type positive displace-
ment meters have tough bronze maincases that
are guaranteed for 25 years, magnetic drive
sealed registers to keep dirt and moisture from
internal parts and specially designed hydro-
dynamically balanced pistons in dual -ported
measuring chambers to virtually eliminate the
forces that cause wear, extending the life of each
meter. You get years of dependable service with
little or no maintenance problems.
Consider these outstanding features:
' Streamlined Flow Pattern allows water to enter
the meter with less obstruction. The dual -port
design helps balance the piston within the meas-
uring chamber, reducing wear and head loss,
providing long service life and dependable ac-
curacy at all flow ranges.
Guaranteed Reliability means that you can buy
with confidence because the SR II Water Meter
is backed by a Bronze -lad Guarantee' Sensus
guarantees that the SR II meter will meet AWWA
new meter accuracy standards for five (5) full
years - and repaired meter accuracy standards
for an additional ten (10) years — a full 15 years
of guaranteed accuracy! Standard registers and
maincases are guaranteed for a full 25 years.
And the MIP (Meter Insurance Plan) and MMP
(Meter Maintenance Plan) from Sensus will pro-
vide extended coverage on SR 11 Water Meters.
Greater Measurement Accuracy is achieved at
all flow ranges, from extremely low flows up to
the highest specified range for each size SR II
meter- Accurate measurement at all ranges —
from leaks to lawn sprinkler service — is as-
sured. No other meter in this class provides as
great a degree of accuracy as the SR II meter
over the full range of flows.
Hermetically Sealed Registers minimize lens
fogging problems or contamination of internal
parts caused by dirt or moisture. Standard direct
read magnetic drive registers feature tempered
glass lenses that resist scratching, discoloring
and breakage. Standard registers are available
in your choice of measurement units. such as
gallons, cubic feet or metrics And, of course.
all feature low flow (leak) detectors.

Tamper Resistance means that the design in-
cludes your choice of either a specially designed
stainless steel locking bolt which requires a spe-
cial authorized toot for removal — or on en-
gineered plastic bonnets, a plastic locking pin'
for tamper detection.
Interchangeability of Parts and Registers is
possible because manufacturing tolerances are
so exact. Internal parts can be interchanged
from SR II meters of the same size with no ap-
preciable difference in the degree of measure-
ment accuracy. No change gears are required.
reducing the need for a large pans inventory.
Bottom plates are available in your choice of
materials to provide protection from freezing, if
needed. All SR 11 meter registers, from the stan-
dard direct read type to generators and a varie-
ty of electronic models, can quickly and easily
be exchanged between same size meters. giv-
ing you expanded flexibitty and a wide range
of options to meet present as well as `uture
needs.
THE SR 11 WATER METER
IS AN OUTSTANDING VALUE.
SR3 Water Meters
5;s" (DN 15mm) through
2" (DN 50mm) Sizes
SR' (Seated Register) Water Meters were the
first oscillating piston -type meters to use a mag•
netic coupling, between measuring elements in
tie measuring chamber, with a hermetically
sealed register. Since the introduction of the SR
"refer design in 1957, this innovative line of pos,
*'ve displacement meters has achieved an en-
viable record of long service and measurement
accuracy. The design features a bronze main -
case and a unique tamper -proof system to pre-
vent unauthorized removal of the register, and
s offered with a choice of bottom olates (for the
S', 3 * and 1' sizes), register types, and much
more.
Consider these great SR Water Meter
features:
Accurate, Long -Term Performance is assured
by the piston -type measuring chamber. The
Proven SR design achieves slow. uniform piston
wear evenly distributed over a large area to pro-
vide years of dependable service.
Tamper -Proof Design means that SR meter
registers cannot be removed without disrupting
the integrity of the maincase an excellent
Choice for installations where tampering might
be a problem. The meter must be disassembled
to remove its register; even then, a special too
s required.
Sealed Registers — The registers are perms.
