Dear Mr. Boggs:
Reference is made to your January 24, 2001 correspondence requesting rescission of the subject
NPDES General Permit. Responding to permit renewal correspondence from our office, you stated the
site was cleaned up and the permit was no longer needed. In accordance with your request, NPDES
General Permit NCG510110 is rescinded, effective immediately.
Please be advised that this permit rescission is based wholly upon your statement that the
activities which would require general permit coverage at the site have ceased or been eliminated.
Division staff has not visited the site to obtain independent verification. Operating a treatment facility,
discharging wastewater or discharging specific types of stormwater to waters of the State without a valid
NPDES permit will subject the responsible party to a civil penalty of up to $25,000 per day. Enforcement
action will be certain for persons that have voluntarily relinquished permit coverage when, in fact,
continuing permit coverage was necessary. If, in retrospect, you feel the site still requires permit
coverage, you should notify this office immediately. Furthermore, if in the future you wish to again
discharge to the State's surface waters, you must first apply for and receive a new NPDES permit.
Rescission of this discharge permit does not absolve you of any other responsibilities you may
have with regard to any groundwater contamination that may still exist at the subject site.
If you have questions about this matter, please contact Bob Sledge at [phone], extension
547 or the Water Quality staff in our Mooresville Regional Office at [phone].

Subject: NPDES Wastewater Permit Coverage, Renewal
Rhodes & Beal Oil/bailey's
COC Number NCG510110
Lincoln County
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 Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548

In accordance with your application for permit renewal, the Division is forwarding the subject NPDES general
permit for petroleum contaminated groundwater remediation systems. This General Permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement. between North
Carolina and the US Environmental Protection Agency dated December 6, 1983 and as subsequently amended.
The Certificate of Coverage previously issued to your facility is now valid under the revised General Permit for
discharges associated with groundwater remediation systems (NCG510000 - issued August 22, 1996). The new General
Permit is more comprehensive, in that it covers remediation of groundwater contaminated with heavier fuels (such as
diesel, fuel oil, and kerosene) as well as gasoline contamination. Please note that the permit has three effluent
limitations pages. The type of contamination at your site (gasoline only, heavy fuels only, or gasoline and heavy
fuels) will determine the effluent limitations for your discharge.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you
have the right to request an individual permit by submitting an individual permit application. Please take notice
that the previously issued Certificate of Coverage is not transferable except after notice to the Division of Water
Quality. The Division of Water Quality may require modification or revocation and reissuance of the Certificate of
Coverage.
This permit does not affect the legal requirements to obtain other permits which may be required by the Division of
Water Quality or permits required by the Division of Land Resources, the Division of Coastal Management, or any
other Federal or Local governmental permit that may be required.
If you have any questions or need additional information, please contact Charles Weaver at telephone number (919)

Installation
ZL CAUTION!
N1 Series meters are in-
tended for use with water
and non -hazardous water -
based fluids only.
1. Position. M Series meters
should be installed in a hori-
zontal position with the register
on top. The meter will operate
in a vertical position, but will
tend to indicate less than actual
flow, and bearing life will be
shortened.
2. Couplings. Most M Series
meters are installed with meter
couplings, and they are sup-
plied with the meter unless it is
ordered otherwise. The meter
thread is IPS (same as pipe
threads, except straight) one
size larger than the meter. For
example, the thread on a 3/4"
meter is 1" IPS. Standard pipe
couplings are sometimes
threaded onto the meter, but
this is not recommended, since
the meter thread is for me-
chanical connection only, and
sealing is done by the gasket in
the meter coupling. (Note:
when installing meter cou-
plings, check to be sure that the
gasket is in place between the
coupling and the meter.) The
advantage of meter couplings is
that they act as unions for the
easy removal of the meter from
the line. Meter couplings
provide standard male NPT
threads the same nominal size
as the meter for easy connec-
tion to the system. The

3. Inlet Disturbance.
Multi -jet meters are less sensi-
tive to turbulence than some
other types of flowmeter, but
five diameters of upstream
straight pipe are recommended.
All M Series meters have built-
in inlet strainers. In installa-
tions with a high degree of
suspended solids, an in -line
strainer upstream of the meter
is a worthwhile precaution.
4. Air Bleed. When the meter
is first installed, trapped air
should be removed if present in
the meter. To do this, loosen
meter couplings slightly and
rotate the meter to an inverted
position. Allow water to flow

El
S
b (COVAT'b.)
through the meter, then
rotate it back to an upright
position and retighten.
5. Electrical Connections.
MR meters are supplied stan-
dard with a twelve foot cable
attached to the sensor. The
MR cable has two conductors
(see the diagram at right for
the correct connections).
6. Pulse Contact. MR meter
sensors respond to a magnet
which is turning on the face
of the meter under the lens.
The sensor gives one output
"Pulse" (on/off) each time a
magnet pole passes. The
magnets have one, two or
four poles. The white dots
on the magnet indicate the
number of poles. For
instructions on change pulse
rate, see the "Maintenance
and Repair" section. The
sensor is designed for elec-
tronic control loads. It
should not be used to switch
power loads such as motors
or lights, and it should not
be connected to 110 VAC
(see "Specifications" for max-
imum load ratings).
Maintenance and
Repair
1. Inlet Strainer Cleaning.
Do this yearly, or as required.
Remove the meter and gently
backflush it to loosen parti-
cles trapped by the -strainer.
2. Calibration Testing.
Meters being used for billing
or for billing -exemption may
be regulated by state agen-
MR Sensor Connection
cies or by water or sewer util-
ities. New M Series meters
meet the American Water
Works Association C708
Multi Jet Meter specification.
Some states require tests at
intervals of eight years for
3/4" meters, six for 1", and
four for 1 1/2" and 2".
Testing can usually be done
by local meter repair facili-
ties authorized for this pur-
pose. Meters used for con-
trol should be checked every
5-10 years.
3. Replacement of Internal
Parts. All of the moving
parts inside an M Series
meter can be replaced by
removing the meter top. For
most applications, this
should not be required for a
number of years. Breakage
in a relatively new meter, is
probably a result of excessive
flow. Compare flow with the
meter maximum to deter-
mine if a larger meter should
be used.
To remove the meter top,
carefully loosen by putting a
bar through the slots on the
meter top and then unscrew.
it. Remove the lens (it some-
times needs gentle prying
with a small screwdriver) and
then lift out the internal
Black
NON POLAR
CONNECTION
Red
assembly. (If necessary,
loosen by rocking it slightly
from side to side.) The
internal assembly pieces -
bottom chamber, top cham-
ber and register, are friction
fitted and can be separated
by hand.
To replace or move the
magnet on the register face,
pull gently on the magnet
with fingers. It is lightly
press -fitted to the shaft. To
install it on another shaft,
put it on and press down
until it bottoms.
4. Changing Pulse Rates.
Remove the meter top as
described above. Following
the pulse rate chart, put a
magnet with the indicated
number of poles in the indi-
cated position.
5. Changing Meter Sensor.
The meter sensor is threaded
hand tight into the lens. To
remove a sensor, unscrew it
by Bind. Screw the replace-
ment sensor in until it bot-
toms.

STAT Series
Sieve Tray Aeration Technology
Carbonair's exclusive STAT series represents the
best choice for low profile air strippers with design
simplicity, flexibility and high performance.
In Carbonair's STAT units, the water and air are
contacted in step -wise fashion on muitiple trays. The
water enters at the top and flows across each tray. The
air passes upwards through openings in the trays, then
bubbles through the water to form "a surface of foam"
which provides extreme turbulence and excellent
volatilization. Since the water in Carbonair's STAT
units flows horizontally across each tray, the traveling
path length of water and the required removal efficiency
can be achieved by increasing both the number and
length of the trays. Therefore, the STAT units provide
much lower tower height than the conventional
packed towers.
Another advantage of Carbonair's STAT units is
that air and blower power consumption are effectively
utilized since a single air stream passes through every
tray before exiting the tower. As a result of minimal
air flows, the organic contaminants a.-e concentrated
and effectively removed by vapor phase carbon.

Low tower height yields numer-
ous other advantages: rapid installation,
easy winterization, inconspicuous
appearance, easy shipping and easy
maintenance. The STAT unit also re-
duces the potential for fouling since it
contains no packing media and provides
an extreme turbulent condition.
Carbonair's STAT units are avail-
able with a number of plate configura-
tions, blowers and controls, and can
achieve removal efficiency up to 99.99%.

System Description
The Carbonair STAT series a*e sieve tray aeration units containing no packing media.
With the STAT unit, the water and air are contacted in step -wise fashion in multiple
trays. The water enters near the top and flows horizontally across each tray and
through a downspout to the tray below. A pressure blower provides air for the
aerating process. The air enters the bottom of the unit and is forced through
openings in the trays, bubbling through the water to form 'a surface of foam' which
provides extreme turbulence and excellent volatilization: The overall effect is a
multiple countercurrent contact of water and air, with each tray having a cross flow
of water opposing a vertical flow of air.
The VCC-laden air passes through mist -eliminating media at the top of the unit and
leaves the STAT through a top flange where it is either discharged to the atmosphere
or treated far removal of the VCCs (such as with carbon adsorption). The treated
water collects in the sump section of the STAT unit and exits (by gravity) via a
unique internal discharge flow modulating valve and flange. In cases where the
treated water must be re -pressurized, a pump -out configuration is available.
By the flow of air continuously opposing the flow of water, a counterflaw, low profile
design provides a natural self -polishing effect because the c!eanest water exiting the
system is contacted by the c!eanest air entering. Since a single airstream passes
through every tray before exiting the tower, the air and blower power consumption
are effectively utilized. As a result of a minimal air flow, the organic contaminants in
the off -gas are concentrated and can effectively be treated.
The STAT series also reduces the potential for fouling since it contains no packing
' media and provides an extreme turbulence condition.

THE MOST SUCCESSFUL AUTOMATIC CLEANUP
PUMPS JUST GOT EVEN BETTER
QED's introduction of the Solo= pumps in 1990
changed cleanup pumping. Thousands are now in
use at remediation projects, hydrocarbon recovery
sites, and landfills across the U.S., Canada, Mexico,
and overseas.
What makes them such a success? They don't need
the external controllers, timers, or downwell probes
used to regulate the duty
cycles of ordinary electric
or pneumatic pumps.
Doing away with con-
trollers makes system
specification and installa-
tion much simpler. It also
eliminates the need for
time-consuming pump
adjustments every time
site conditions change.
Since the original
release, QED engineers
have continuously im-
proved the design, mate-
rials, and features. The
result, the new -genera-
tion Solo II pump, should
be the industry work-
horse for moderate -flow,
4" well cleanup for years
to come.
now with improved performance,
lower prices, and a 2-year warranty.
HOW SOLO II PUMPS WORK
Each Solo H pump (U.S. Patent No. 5,141,404) runs
itself, with an internal float system and a magnetic air
control valve. The float follows changing liquid levels
in the pump, signaling the valve to turn the air supply
on as soon as the pump is full and off when empty.
The air control mechanism uses a magnetic relay to
isolate it from pumped fluids, and is contained in a
compact cartridge that can be easily replaced if neces-
sary without disassembling the pump.
Solo II systems are easier to install, with no air
cycle or on/off level controllers at the wellhead.
The best-selling automatic pump-
There are no electrical connections or pneumatic logic
lines —just supply air and discharge tubing to the
well.
EFFICIENT, RELIABLE, LOW -MAINTENANCE
Every pump constantly reacts to changes in its well
vield, pumping at the optimized rate or shutting
down if the well drops below the required level.
Because cycling is controlled downwell, the pump is
either refilling or dis-
charging 100% of the
time. There's no waiting
between cycles for the
entire length of air supply
tubing to vent and re -
pressurize. This increases
pumping efficiency and
reduces air requirements.
High -clearance, self-
cleaning ball check valves
and proven, chemical -
resistant materials deliver
dependable operation
without clogging or
breakdowns. All parts are
rated for millions of
cycles and are easily field -
replaceable; there's no
down -time while you
send pumps out for
repairs.
BETTER PUMPS, BETTER WARRANTY, BETTER PRICE
How are Solo II pumps better? Specially -cured
epoxy floats withstand even higher temperatures and
a wider range of aggressive fluids without saturation.
New air control valves improve start up, even after
extended system shutdowns. Materials and fittings
have been changed to make pumps easier to use and
maintain. QED is so confident in Solo II reliability,
we've extended the warrantV to two vears, at least
double the competition's.
A better pump and better warranty —but best of
all, we've lowered the price. You'll save 20%—mak-
ing Solo II pumps the best value in cleanup pumping....;'

QED's exclusive iacketed Tubing, with a continuous nylon
sheath, helps prevent hang
ups and loops, makes installation easier
(especially in narrow or obstructed casing), and is lightweight with
exceptional chemical resistance, outside and in.
Tubing sets are supplied cut to custom lengths. Jacketed tubing
and sheath are both Nvlon 12, which doesn't swell in water and
proNndes excellent resistance to most liquids and cleanup condi-
tions, including hydrocarbons, fuels, and alkalies. For extremes of
acidity, consult QED for alternative.
Two tubing packages are
available for Solo II pumps. The Model

Installation
,L CAUTION!
M Series meters are in-
tended for use with water
and non -hazardous water -
based fluids only.
1. Position. M Series meters
should be installed in a hori-
zontal position with the register
on top. The meter will operate
in a vertical position, but will
tend to indicate less than actual
flow, and bearing life will be
shortened.
2. Couplings. Most M Series
meters are installed with meter
couplings, and they are sup-
plied with the meter unless it is
ordered otherwise. The meter
thread is IPS (same as pipe
threads, except straight) one
size larger than the meter. For
example, the thread on a 3/4"
meter is 1" IPS. Standard pipe
couplings are sometimes
threaded onto the meter, but
this is not recommended, since
the meter thread is for me-
chanical connection only, and
sealing is done by the gasket in
the meter coupling. (Note:
when installing meter cou-
plings, check to be sure that the
gasket is in place between the
coupling and the meter.) The
advantage of meter couplings is
that they act as unions for the
easy removal of the meter from
the line. Meter couplings
provide standard male NPT
threads the same nominal size
as the meter for easy connec-
tion to the system. The

3. Inlet Disturbance.
Multi -jet meters are less sensi-
tive to turbulence than.some
other types of flowmeter, but
five diameters of upstream
straight pipe are recommended.
All M Series meters have built-
in inlet strainers. In installa-
tions with a high degree of
suspended solids, an in -line
strainer upstream of the meter
is a worthwhile precaution.
4. Air Bleed. When the meter
is first installed, trapped air
should be removed if present in
the meter. To do this, loosen
meter couplings slightly and
rotate the meter to an inverted
position. Allow water to flow

Fausl
fluid adkontrals
through the meter, then
rotate it back to an upright
position and retighten.
5. Electrical Connections.
MR meters are supplied stan-
dard with a twelve foot cable
attached to the sensor. The
MR cable has two conductors
(see the diagram at right for
the correct connections).
6. Pulse Contact. MR meter
sensors respond to a magnet
which is turning on the face
of the meter under the lens.
The sensor gives one output
"pulse" (on/off) each time a
magnet pole passes. The
magnets have one, two or
four poles. The white dots
on the magnet indicate the
number of poles. For
instructions on change pulse
rate, see the "Maintenance
and Repair" section. The
sensor is designed for elec-
tronic control loads. It
should not be used to switch
power loads such as motors
or lights, and it should not
be connected to 110 VAC
(see "Specifications" for max-
imum load ratings) .
Maintenance and
Repair
1. Inlet Strainer Cleaning.
Do this yearly, or as required.
Remove the meter and gently
backflush it to loosen parti-
cles trapped by the strainer.
2. Calibration Testing.
Meters being used for billing
or for billing -exemption may
be regulated by state agen-
MR Sensor Connection
ties or by water or sewer util-
ities. New M Series meters
meet the American Water
Works Association C708
Multi Jet Meter specification.
Some states require tests at
intervals of eight years for
3/4" meters, six for I", and
four for 1 1/2" and 2".
Testing can usually be done
by local meter repair facili-
ties authorized for this pur-
pose. Meters used for con-
trol should be checked every
5-10 years.
3. Replacement of Internal .
Parts. All of the moving
parts inside an M Series
meter can be replaced by
removing the meter top. For
most applications, this
should not be required for a
number of years. Breakage
in a relatively new meter, is
probably a result of excessive
flow. Compare flow with the
meter maximum to deter-
mine if a larger meter should
be used.
To remove the meter top,
carefully loosen, by putting a
bar through the slots on the
meter top and then unscrew.
it. Remove the lens (it some-
times needs gentle prying
with a small screwdriver) and
then lift out the internal
Black
NON POLkR
CONNECTION
Red
assembly. (If necessary,
loosen by rocking it slightly
from side to side.) The
internal assembly pieces -
bottom chamber, top cham-
ber and register, are friction
fitted and can be separated
by hand.
To replace or move the
magnet on the register face,
pull gently on the magnet
with fingers. It is lightly
press -fitted to the shaft. To
install it on another shaft,
put it on and press down
until it bottoms.
4. Changing Pulse Rates.
Remove the meter top as
described above. Following
the pulse rate chart, put a
magnet with the indicated
number of poles in the indi-
cated position.
5. Changing Meter Sensor.
The meter sensor is threaded
hand tight into the lens. To
remove a sensor, unscrew it
by hand. Screw the replace-
ment sensor in until it bot-
toms.

Permit # NCG510110
Dear Mr. Gleason:
In accordance with the General NPDES discharge permit NCG510110, this letter provides
the 5-day written notification to the NPDES compliance group of a permit exceedance at
the referenced site. The permit exceedance was for the discharge of benzene and
toluene above the stated daily maximum limit.
The groundwater remediation system at Bob's Food Mart location was started on January
12, 1995. After 24-hrs of operation of the groundwater remediation system, groundwater
samples were collected (influent, midfluent and effluent) and analyzed for BTEX and
MTBE. On January 20, 1995, Handex received laboratory results for the discharge water
from the referenced groundwater remediation system. The analytical results were
reviewed by Handex on January 23, 1995. The sample concentrations of benzene at 363
pg/I and toluene at 691 ug/I exceeded the daily maximum concentrations listed in the
permit for benzene of 142.8 Ng/I and toluene of 22 ,ug/I.

Handex has dispatched a technician to trouble shoot the system and make the necessary
repairs. Handex will notify the NCDEHNR of the reduction in the levels after the next
sampling event takes place.

Route 8, Box 122, Hickory, Lincoln County, NC
Permit # NCG510110
Dear Mr. Gleason:
This update report on the groundwater remediation system located at the above
referenced facility is being submitted per our January 23, 1995 letter. The groundwater
system was repaired on January 23, 1995 and groundwater samples (influent, midfluent,
and effluent) were collected on January 24, 1995. The groundwater remediation system
was shut down after collecting the groundwater samples.
The groundwater samples were analyzed for BTEX and MTBE by Flowers Chemical
Laboratory. On January 30, '1995, Handex received laboratory results and the
groundwater effluent sample results were found to be in compliance with NPDES
discharge limits. A copy of the laboratory analytical results is enclosed for your reference.
On January 31, 1995, Handex contacted Mr. Samar Bou-Ghazale at NCDEM Mooresville
office and informed him about the groundwater effluent results being in compliance with
NPDES discharge limits. The groundwater remediation system will be operational before
Friday, February 3, 1995.

ppppppp,

PART IV - EVALUATION AND RECOMMENDATIONS
Petroluem World, Inc. proposes to discharge an undetermined
amount of treated groundwater to Rockdam Creek. The groundwater
in the area where Bob's Superette (a convenience store with gas
station) is located has been contaminated with petroleum products
due to leakage of an underground storage tank. It was believed
that the extent of petroleum contamination was not extensive.
A water supply well for a mobile home park (Heavner's Mobile Home
Park) is located down -gradient approximately 70 feet from the
spill site. However, the well has not become contaminated.
The recovered groundwater will be treated using a combination
of counter -current air stripping followed by granular activated
carbon adsorption to eliminate volatile organics and polish the
effluent prior to discharging.
On -site investigation indicated that the receiving water

appeared to have a significant amount of
proposed wastewater. However, this flow

for completion of a National Pollution Discharge Elimination System
Permit (NPDES) for the above referenced facility:
1. A completed NPDES Application - Short Form C-GW.
2. A delegation of authority letter from Mike Frost of
Petroleum World, Inc.
3. A site vicinity map showing the discharge piping route.
4. A copy of the Corrective Action Plan (CA_D) fcr thic
facility that serves as a engineering proposal.
5. A check for the amount of $400.00 payable to the North
Carolina DEHNR for the permit processing fee.
As discussed in section 1.0 of the CAP and in Table 1 of the CAP,
several different groundwater treatment alternatives were
considered for remediation of the groundwater at this facility.
The groundwater treatment technology that was selected for use at
this facility was a combination of couter-current air stripping
followed by granular activated carbon (GAC) adsorption. Air
stripping of volatile organic compounds (VOC's) from groundwater
using a packed tower is capable of obtaining high removal
efficiencies. GAC absorption was proposed as post -treatment to
polish the effluent groundwater before discharge.

Shield Environmental Associates, Inc. (Shield, formerly PTSI)
contacted the Lincoln County public works department to identify
any municipal sewer lines into which the wastewater could be
discharged. Reportedly, there are no municipal sewer lines located
near this facility and there are no plans to install sewer lines in
western Lincoln County in the near future; therefore, the water
will be discharged directly into Rockdam Creek (see attached Figure
1) .

miles west of the city of Lincolnton on NC Highway 27. Please
refer to Figure 1 - Site Vicinity Map, which is a portion of the
Lincolnton West 1973 USGS topographic sheet. Figure 2 - Site Plan,
provides specific details of the facility.
Petroleum World, Incorporated retained Petroleum Testing Services,
Incorporated (PTSI) to perform the Preliminary Assessment, in
addition to the recently submitted Comprehensive Site Assessment.
The Corrective Action Plan (CAP) which follows will address the
Department of Environment, Health, and Natural Resources
correspondence of June 19, 1991. The principle objective of this
CAP is directed towards restoration of the near surface
groundwaters beneath this facility to water quality standards as
established by 15A NCAC 2L, or to levels which are economically
and/or technologically feasible.

In developing this CAP, various available technologies which could
meet the primary objective were reviewed. The procedures which
were considered have been listed in Table 1, as well as their major
advantages/disadvantages, cost effectiveness, and system
reliability. After evaluation of each of the listed technologies,
PTSI recommends the installation of a pump and treatment system
utilizing an air stripping tower in conjunction with granular
activated carbon.
2.0 AREA GEOLOGY
The Bob's Superette site is geologically located in the Inner
Piedmont Belt. The Inner Piedmont Belt is one of the largest of
North Carolina's geologic belts, encompassing fifty to sixty miles
in width at it's widest point. The western border of this belt is
defined by the Brevard Zone, the eastern contact is the Kings
Mountain belt, and the Charlotte Belt to the northeast. The rocks
to the east are usually characterized by a lower metamorphic grade.
The Inner Piedmont is host to the highest grade metamorphic rocks
in North Carolina's Piedmont. The predominant rock type is thought
to be an assemblage of complexly mixed mica gneisses and schists.
The foliation of the gneisses and schist generally dips at low to
moderate angles (Hatcher, 1978).

Granitic rocks occur in the Inner Piedmont, but not to the extent
of the gneisses and schists. The grantic bodies are considered to
occupy "widely spaced sheets and lenses that intrude the gneisses
and schists."
The geologic history, stratigraphy, and source of this belt is not
clearly understood due to the complexities associated with high
grade regional metamorphism. It is currently accepted that the
gneisses and schists were derived from upper Precambrian and lower
Paleozoic sedimentary and volcanic rocks, which have experienced
several tectonic episodes.
The 1985 edition of the North Carolina Geologic map depicts the
rocks underlying the site area as interlayered amphibolite and
biotite gneiss; with minor hornblende gneiss, metagabbro, mica
schist and granitic rocks.

3.0 SUMMARY OF HYDROCARBON CONTAMINATION
Page 4
The extent of hydrocarbon contaminated groundwater has been
delineated, in both the vertical and horizontal direction, by the
installation of ten (10) shallow type II monitoring wells and one
(1) type III vertical extent well. Currently, the majority of
contamination appears to be confined to the excavated tank pit area
and extends slightly toward the southeast. Total BTEX
concentrations from groundwater samples collected in this area
ranged from 42,320 PPB in monitoring well 8 (MW-8) to 209,000 PPB
in monitoring well one (MW-1). The most recent groundwater quality
analytical results are summarized in Table 2. Free phase product
is present in monitoring well three (MW-3), and has been removed
from this well on a weekly basis by manual bailing techniques.
In addition, the extent of soil contamination appears to be
confined to the excavated tank pit area, as the soil samples
collected for laboratory analysis of Total Petroleum Hydrocarbons
(TPH) were all reported less than ten (<10) parts per million
(PPM), as reported on March 3, 1991 and May 17, 1991. Soil samples
submitted for laboratory analysis were those from each boring with
the highest recorded organic vapor analyzer field screenings, and
from the total depth of boring achieved.

PTSI No. 903327
Page 5
During UST excavation procedures, approximately 575 tons of
contaminated soil was removed, stockpiled, and subsequent approval
for landfarm application was granted. After free phase product
removal, PTSI proposes an investigation to delineate the extent of
remaining soil contamination and associated corrective action
activities.
4.0 CORRECTIVE ACTION PLAN OBJECTIVES
The primary objectives of the corrective action plan are as
follows: 1) mitigate the migration of hydrocarbon constituents in
the surficial aquifer, 2) recover free -phase product on the water
table, and 3) restoration of groundwater quality to NC
Administrative Code Title 15 Subchapter 2L Section .0202 standards.
These objectives will be accomplished by installing a dual recovery
pump system into the existing recovery well (RW-1) for product
recovery. An additional recovery well will be installed in the
vicinity of monitoring well eight (MW-8) to enhance contaminant
plume recovery. A permit application for the installation of
recovery well two (RW-2) has been included as Appendix A. Two
water table depression pump systems are proposed to create

Page 6
sufficient drawdown to capture the dissolved phase contaminants.
Treatment of recovered groundwater will be accomplished by
volatilization of volatile organic constituents by packed column,
air stripping technology. Effluent discharge from the stripping
tower will be pumped through two pairs of parallel granular
activated carbon drums, which should remove the remaining volatile
organic constituents, and the naphthalenes to nondetectable limits,
prior to discharge into Rockdam Creek (Noonan, p. 53 and Nyer, pps.
76-77). Recovery system treatment efficiency will be addressed in
detail in a later section. PTSI is in the process of completing
an NPDES Permit application with the State of North Carolina for
groundwater discharge from this site.

5.0 DESIGN OF THE REMEDIAL ACTION SYSTEM
5.1 Pump Test Results
Page 7
The first step in designing a treatment system for this site was
the determination of flow rates that would exert hydrodynamic
control over the area of interest. An abbreviated pump test was
performed on July 26, 1991 utilizing the existing recovery well
(RW-1). Complications during the test prevented consistent pumping
of the aquifer. As a result, certain assumptions were made in
calculating the aquifer characteristics.
The pump test lasted for approximately two hours, and during this
time the pumping rate fluctuated between 1.25 gallons -per -minute
(GPM) and 1.5 GPM. In order to estimate the hydrodynamic
characteristics of the aquifer, these two values were averaged and
multiplied by a safety factor of 1.2 to arrive at a design pumping
rate (Q) of 1.65 GPM. The hydraulic conductivity (K) of the
unconfined aquifer was calculated by the following equation:
K = 1055 0 log (r2/ri) (Driscoll, p.215)
(h22 - h12)

`Corrective Action Plan
Bob's Superette
Highway 27 North
Lincolnton, North Carolina
PTSI No. 903327
Page 8
where rl = distance to the nearest monitor well (ft)
r2 = distance to the farthest monitor well (ft)
hi = saturated thickness at the nearest monitor well (ft)
h2 = saturated thickness at the farthest monitor
well (ft)
From this equation, the hydraulic conductivity was calculated to be
27.9 gallons per day per square foot (gpd/ft2). The specific
yield could not be accurately calculated from the available data,
therefore a specific yield (Sy) of 0.03 was selected from the
t range of published values for unconfined aquifers (Driscoll,
p.237). The transmissivity (T) was calculated to be 1032 gpd/ft by
utilizing the following equation:
T = Kb (Freeze, pps. 59-61)
where b = saturated thickness of the aquifer (ft) - estimated
at 36.99 ft.
K = hydraulic conductivity (gpd/ft2)
Using these values and the Cooper -Jacob Modified Nonequilibrium
Equation (Driscoll, p.219), theoretical cones of influence for
various recovered groundwater flow rates were predicted. For each
flow rate, the resultant drawdowns that would be achieved at
various distances from the recovery wells were calculated (Refer to
Table 3 - Distance vs. Drawdown Calculations). These calculations
were based on a pumping duration of twenty-five (25) days, with no
precipitation.

Highway 27 North
Lincolnton, North Carolina
PTSI No. 903327
Page 9
An approximate drawdown of 0.54 feet at a distance of 100 feet from
the recovery wells was chosen as a design parameter from these
calculations. Please note (refer to Figure 4) that the resultant
drawdown cone of 0.54 feet at the anticipated 100 foot radius from
RW-1 alone, would not be sufficient to fully capture the
contaminant plume. A second recovery well (RW-2) is proposed
(refer to Figure 2) to completely capture the contaminant plume.
5.2 Pump Selection
Due to the presence of free phase product detected in MW-3, dual
pump systems are proposed for both recovery wells. Groundwater
Recovery Systems, Inc. (GRS) dual pump assemblies were selected for
this application. A groundwater flow rate of 1.65 GPM (the
derivation of this value is discussed in Section 5.1 - Pump Test
Results) from each recovery well was selected to calculate
frictional losses in the piping. These frictional losses were
calculated using Darcy's Equation (Perry, p. 5-24). Based on the
depth of the recovery wells, the height of the stripping tower,
and distance of recovery wells from the treatment unit, the
pressure head that the pumps must overcome was calculated to be
approximately 68 feet. From the pump curves provided in Appendix
B, two Grundfos Model 5E5 submersible water pumps were selected.
These pumps are capable of 130 feet of pressure head at 1.65 GPM.

lCorrdctive Action Plan
Bob's Superette
Highway 27 North
Lincolnton, North Carolina
PTSI No. 903327
Page 10
The product recovery pumps were selected because of probable
migration of free phase product into the recovery wells due to
induced drawdown. Two GRS Tuthill D6089 product pumps are proposed
to be used in tandem with the water table depression pumps. The
water table depression pumps will enhance free -phase product
recovery by creating cones of depression for product migration and
accumulation.
Both pumping systems will be equipped with water and product probes
interconnected by a control panel. The ground water will be pumped
through one inch inside diameter (I.D). Parker Push Lock tubing
that is capable of withstanding 200 pounds per square inch (psi)
water pressure. The product will be pumped through one quarter
inch I.D. polypropylene tubing to a 1000 gallon product recovery
tank. The recovery tank will be equipped with a tank full sensor
to automatically shut off the pumps and prevent product overflow.
5.3 Air Stripping Tower
Laboratory analysis of groundwater quality samples collected on
February 28, 1991 from MW-1 and MW-2 were used to predict the
contaminant levels expected in the recovered groundwater. The
contaminant levels from these two wells were averaged and
multiplied by a safety factor of 1.2 to obtain design levels.

,Corrective Action Plan
Bob's Superette
Highway 27 North
Lincolnton, North Carolina
PTSI No. 903327
Page 11
The design influent levels were: benzene, 25.8 PPM; toluene, 65.4
PPM; ethylbenzene, 12.2 PPM; total xylenes, 68.4 PPM; methyl
tert-butyl ether (MTBE), 19.2 PPM; and naphthlalene, 0.71 PPM
(please refer to Appendix C for laboratory results). The actual
levels that are found during start up should closely reflect these
levels as summarized in Table 4 - Projected System Efficiencies.
The air stripping tower was designed using a computer program
called Airstrip. The packing material selected for the air
stripping tower was one inch diameter Jaeger Tripacks, a plastic
random packing with 84.7 square feet of surface area per cubic
foot. An air -to -water ratio of 150 was chosen for this
application. Please note that the design output for m-xylene
represents the contaminant level for total xylenes. Specific
compounds are required for input to the Airstrip program; m-xylene
was selected as a representative compound for total xylenes during
this application.
Airstrip utilizes the design information along with Onda's
correlation to predict the height of a transfer unit. From this
information, the height of the packed tower can be calculated that
would obtain the necessary effluent contaminant levels. After a
review of the model results, a 12-inch I.D. tower with a packed
height of 20 feet and an overall height of 24 feet was selected.
The computer output from the program can be found in Appendix D.

5.4 Blower Sizing
Page 12
From the computer model, the pressure loss per foot of tower height
was less than 0.06 inches of water. For a packed height of 20 feet
the minimum pressure the blower must overcome is 1.2 inches of
water. An American Fan Size 9-1015 was chosen for this tower.
This blower is capable of 160 cubic feet per minute (CFM) at 5.5
inches of water and 480 CFM at 1.0 inch of water. This allows for
a minimum air -to -water ratio of 359 and a maximum ratio of 1088.
The blower performance curve is enclosed in Appendix B.
5.5 Carbon Adsorption System
A Continental Environmental Services (CES) granular activated
carbon (GAC) system has been proposed for this application. The
system is comprised of a sump, a backwash trickle filter, particle
filters, repressurization pumps, GAC working and polishing columns,
and ancillary sampling ports. Backwashing will be programmed to
occur three times a day. Detailed information including a system
schematic is provided in Appendix E. The granular activated carbon
filters will be changed and disposed of every six (6) months or at
breakthrough, whichever occurs first. Based upon influent
contaminant concentrations, breakthrough should not occur during
the six (6) month period; approximately 12 pounds of the available
380 pounds of granular activated carbon is calculated to be spent
during this period.

5.6 Fouling/Dissolved Solids
Page 13
Aeration of the water during air stripping will cause dissolved
solids to precipitate, resulting in tower fouling. Unless fouling
proves to be excessive, it will be dealt with by cleaning and/or
changing the tower packing periodically. The blower has been sized
to accommodate a possible increase in static pressure resulting
from precipitate build up. When the tower pressure differential
reaches five to six inches of water, the packing will be changed.
5.7 Piping Layout
Groundwater will be pumped to the compound area from each recovery
well through one -inch Parker Push Lock tubing that is capable of
withstanding 200 PSI water pressure. Totalizing flow sensors will
be placed on both influent lines. The groundwater will flow
through the air stripper to the GAC system and into the 3-inch
schedule 40 PVC effluent pipe. The groundwater will then gravity
drain to the discharge point (see Figure 5 for Recovery System
Layout.)

5.8 Emissions/Discharge
Page 14
PTSI contacted the NC DEM, Mooresville, North Carolina Office air
quality engineer to register the proposed air stripping tower. The
unit was registered via correspondence dated August 20, 1991 (a
copy is provided in Appendix F). PTSI is in the process of filing
for a National Pollutant Discharge Elimination System Permit to
discharge treated groundwater. PTSI plans to discharge groundwater
from the treatment system into Rockdam Creek (see Figure 5 -
Recovery System Layout).
5.9 Safety Precautions
Throughout the design process a safety factor of 1.2 was used in
the design calculations. This will enable the system to
accommodate fluctuations in predicted groundwater flow rates and
contaminant levels. In addition, the equipment associated with the
system contains some inherent physical safety features.
The dual pump systems are equipped with high water shut off sensors
that prevent water from being pumped into the recovery tank. The
recovery tank has a tank full sensor that will also shut off the
pumps to prevent the tank from overflowing.

Corrective Action Plan
Bob's Superette
Highway 27 North
Lincolnton, North Carolina
PTSI No. 903327
Page 15
The air stripping tower is equipped with a low pressure interlock
that senses changes in pressure inside the tower. Should the
blower stop running, the interlock switch will shut down the entire
system to prevent groundwater from flowing untreated through the
tower.
The air stripping tower, granular activated carbon system (GAC)
control panel and recovery tank will be surrounded by a locked
compound area. The GAC system will be contained in a heated 8 foot
by 10 foot housing to prevent the piping from freezing and bursting
in the winter. This housing will be kept locked to prevent
unauthorized access. The entire system will be checked periodically
to insure that the system is functioning properly both mechanically
and electronically.
6.0 RAS OPERATION AND MAINTENANCE
Installation of the Remedial Action System (RAS) will begin as soon
as practicable after approval of the CAP. The system will be
placed on a monitoring schedule consisting of weekly site visits
for the first three months of operation and monthly thereafter, for
the first year. During these visits, the flow rates, water levels
and product levels will be recorded, and water samples will be
collected at the following locations: influent to the air

stripping tower, effluent from the air stripping tower, between
columns and effluent from the GAC system. These samples will be
analyzed by EPA methods 601, 602 (expanded) and 625. Additional
sampling and analysis may be required to confirm that the treatment
system's water quality meets the terms of the NPDES permit. All
monitor wells and domestic water supply wells within 250 feet of
the treatment system will be sampled quarterly utilizing EPA
Methods 601, 602 (expanded), and 625.
Maintenance will be performed on the system during scheduled site
visits and whenever necessary. The pumps and probes from the
recovery wells will be removed and steam -cleaned periodically. The
tower packing in the air stripper will be changed or cleaned as
necessary. The timer on the granular activated carbon columns will
be set so that backwashing of the aggregate filters occurs three
times daily. Electrical checks will be made on the control panels
and the backwashing control valves to insure proper operation of
the system. The physical appearance of the compound will also be
maintained throughout the life of the project.

Attention: Mr. Charles Lavender
Subject: Analysis of 4 Water Samples, Received 6/25/91.
The water samples were analyzed for purgeable halocarbons according to
U.S. EPA Method 601 (Federal Register, Volume 49 No. 209, Oct. 26,
1984; Page 29). Results are presented in Table 1. The method can be
summarized as follows:
Helium is bubbled through an aliquot of a water sample
contained in a specially designed purging chamber at ambient
temperature. The purgeable halogenated organic compounds
are efficiently transferred from the aqueous phase to the
vapor phase. The vapor is swept through a sorbent column
where the purgeables are trapped. After purging is
completed, the sorbent column is heated and back flushed
with helium to desorb the purgeables onto a gas
chromatographic column. The gas chromatograph is
temperature programmed to separate the purgeables that are
then detected with a Hall detector.
The water samples were analyzed for purgeable organic compounds
according to U.S. EPA Method 8240 (Test Methods for Evaluating Solid
Waste--SW846, 3rd Ed.,1986). Results are presented in Table 2. The
method can be summarized as follows:
Helium is bubbled through a measured aliquot of sample in
organic free water contained in a specially designed purging
chamber. The purgeable volatile organic compounds are
efficiently transferred from the aqueous phase to the vapor
phase. The vapor is swept through a sorbent column where
the purgeables are trapped. After purging is completed, the
trap is heated and back flushed with helium to desorb the
purgeables onto a gas chromatographic column. The gas
chromatograph is temperature programmed to separate the
purgeables that are then detected with a mass spectrometer.

Qualitative identification of the priority pollutants is performed
initially using the relative retention times and the relative abundance
of three unique ions. The entire mass spectrum is checked before any
final identifications are recorded. Quantitative analysis is performed
by the internal standard method using a single characteristic ion and
response factors obtained from a daily calibration standard. In the
tables, an entry such as "<5" means that the compound was not found at
a level above the laboratory's reporting limit. The reporting limit,
which is based on EPA reporting levels, has been corrected for any
sample dilution.
Prior to analysis, every sample is spiked with surrogate compounds as
part of Mid-Pacific's Quality Control Program. These compounds
simulate the behavior of compounds of interest and confirm that
acceptable recoveries are being achieved on every sample. The results
of surrogate recoveries are reported with the sample results.
If you should have any technical questions, please contact the
undersigned at [phone].

Attention: Mr. Charles Lavender
Subject: Analysis of 9 Water Samples, Received 3/5/91.
The water samples were analyzed for purgeable aromatic compounds
according to U.S. EPA Method 602 (Federal Register, Volume 49 No. 209,
Oct. 26, 1984; Page 40). Results are presented in Table 1. The
method can be summarized.as follows:
Helium is bubbled through a 5-mL water sample contained in a
specially designed purging chamber at ambient temperature.
The purgeable aromatic organic compounds are efficiently
transferred from the aqueous phase to the vapor phase. The
vapor is swept through a sorbent column where the purgeables
are trapped. After purging is completed, the sorbent column
is heated and back flushed with helium to desorb the
purgeables onto a gas chromatographic column. The gas
chromatograph is temperature programmed to separate the
purgeables which are then detected with a PID detector.
The samples were analyzed for polynuclear aromatic hydrocarbons
according to EPA Method 610. The samples were extracted with methylene
chloride and then solvent -exchanged in acetonitrile. The sample
