1.0 PROJECT INFORMATION
The U-Filler Up Service Station No. 44 is located approximately 0.4 mile south of the
intersection of South Cannon Boulevard and Fairview Street in Kannapolis, North Carolina. The subject
site is a former service station and is no longer in operation. Reportedly, one 12,000 gallon gasoline and
three 10,000 gallon gasoline underground storage tanks (USTs) were removed from the site. Soil
impacted with total petroleum hydrocarbons was previously reported at a concentration ranging between
410 to 9,000 parts per million (ppm).
2.0 STATEMENT OF PURPOSE
Soil vapor extraction is proposed to treat the petroleum -impacted soil that remains in place. The
purpose of the vapor extraction system is to enhance the volatilization of organic compounds within the
soils and to induce oxygen flow, thereby increasing the potential for natural biodegradation of the in -situ
petroleum -impacted soils.
3.0 PROPOSED SOIL VAPOR EXTRACTION SYSTEM
Five (5) vapor recovery wells are proposed at the site as shown on the attached drawing,
referenced as VR-1 through VR-5. The detail piping is also shown on the drawing. The Spray Aeration
Vacuum Extraction (SAVE) system is proposed for the vapor extraction system. Manufacturers literature
for the SAVE system is contained in Appendix A.
The soil vacuum extraction system consists of a vacuum pump driven by an internal combustion
engine. The vacuum on the extraction wells causes the hydrocarbons to volatilize and flow with the air
into the well and into the vacuum pump. The vapors drawn by the vacuum pump are directed to the
intake of the engine where they are mixed with the auxiliary fuel (propane) and then burned in the
engine through the process of thermal oxidation. Temperatures can exceed 5000' F, thus consuming the
hydrocarbon mixture. The engine exhaust flows into a catalytic converter then through an engine muffler
before final discharge. The engine's air to fuel ratio can be adjusted to maintain efficient combustion.
The vapors from the wells are combined with the fuel from the carburetor, thus resulting in minimal
emissions from the engine.
3.1 System Design
The proposed SAVE system is a four cylinder internal combustion engine fueled by propane. The
engine is equipped with a three way catalytic converter and an automobile sound exhaust system. The
equipment manufacture system components are contained in Appendix A and equipment specifications
are contained in Appendix C. A moisture collection drum will be placed in the vapor influent line prior
to entry into the engine. The vacuum pump is designed to produce a vacuum flow rate of 40 to 80 cfm
Page 1

at a maximum vacuum of 15 inches mercury gage.
3.2 Air Emission Considerations
Vapors extracted from the extraction wells will be piped to the engine for treatment prior to
discharge to the atmosphere. Potential emissions data calculations are contained in Appendix B. The
potential emissions for benzene is estimated at 0.11 pounds per day. Historical data reports the system's
efficiency at 99% for petroleum vapor compounds. A copy of operational data for emissions data
collected from another SAVE system is included in Appendix D. Based on the systems reported
performance, the TPH emissions is expected to produce about 2.4 pounds per day.
3.3 Proposed System Monitoring
The proposed monitoring of the SAVE system will include an HORIBA MEXA-534GE
automotive emission analyzer. Literature for the monitoring system is contained in Appendix A. The
analyzer is capable of analyzing hydrocarbons (HC), CO, CO2 and 02. The proposed monitoring will be
conducted at start up then followed with weekly measurements for the first month of operation. Both
influent and effluent will be measured to assess the efficiency of the SAVE system. During operation,
maintenance of the SAVE system will be performed as necessary to keep the system at optimum
efficiency.
4.0 CONSTRUCTION SPECIFICATIONS

_ AN ADVANCED
SOLUTION
The RSI S.AY.E. System combines air
stripping, vacuum extraction and
combustion technologies to provide
a complete remediation package.
Capable of treating contaminated
soil, groundwater and free floating
product, the SAME. System offers
significant advantages over conven-
tional remediation methods. Our
process has been sited by the
California Regional Water Quality
Control Board as the best available
technology economically achievable
for the treatment of gasoline contami-
nated groundwater.
U.S. Patent

GROUNDWATER
REMEDIATION
The RSI S.A.V.E. System remediates
water contamination using spray
aeration. Unlike air strippers which
move air quickly over the surface of
hydrocarbon laden water, spray
aeration accomplishes volatilization by
spraying water droplets containing
hydrocarbons into the air. Combining
vacuum and heat with spray aeration
enhances the separation of hydrocar-
bons in two ways. First, with reduced
pressure the temperature at which
hydrocarbons vaporize drops. Second,
an increase in temperature from the
addition of heat generated by the
engine increases the potential for
hydrocarbon vaporization further. By
spraying heated water into a vacuum,
the S.A.V.E. System takes advantage
of both these principles. This combina-
tion of technology makes the S.A.V.E.
System significantly more effective at
hydrocarbon separation than conven-
tional air stripper systems.
The S.A.V.E. System is more cost
effective too. With no costly packing
material to foul or replace, the major
maintenance expense of an air
stripper is completely eliminated.

The soil vacuum extraction system
consists of a vacuum pump driven by

SAVE. System vacuum extraction is
proven effective for removing free
phase liquid volatile hydrocarbons
floating on the water table. Our
technology is more efficient than
traditional skimming for three reasons.
First, as free product thickness
decreases, recovery rates from free
product pumping also decrease. This
is because most of the product is
contained in the capillary fringe and is
under the force of a capillary vacuum.
The SAVE. System overcomes this
barrier because the induction of air
flow over the product and subsequent
in -site volatilization are not affected by
capillary forces. Second, the S.A.V.E.
System creates a vacuum in the recov-
ery well which counteracts capillary
forces and draws liquid hydrocarbons
into the well more quickly. Finally,
since the recovered free product is
completely destroyed as fuel in the
engine, there is no need for costly
storage or disposal of liquid
hydrocarbons.

A WORLD AHEAD IN ANALYZER TECHNOLOGY HORIBA
AUTOMOTIVE
EMISSION
ANALYZER
MEXA-534GE
HC,CO,,CO2 and 02
The mini MEXA is magic
SOLID-STATE ANALYTICAL
SYSTEM
MEXA-534GE is based on the principle
of non-dispereive infrared (NDIR)
analysis using pyroelectric detectors
with integrated FET and solid-state
band pass filters for precise infrared
detection. The sophisticated system
incorporates an innovative single -cell
that analyzes lrp to three components,
HC, CO and COS, simultaneously.
The CO2 monitoring function enables
the instrument to be equipped with an
automatic alarm system to prevent
erroneous readings caused by improper
sampling of auto exhaust. The analyzer
offers an excellent system for checking
span readings without the use of stand-
ard gasrs or a mechanical checker, and
also features a short warm-up time of
only 10 minutes and fast response time
of 901i'. response in 10 seconds* with a
5 meter sample line. ('exc(7pt 0')
TOUCH PAD CONTROLS
All controls are flush with the front
panel and rationally laid out. The clear-
ly labelled panel assures error -free
operation at a touch of the appropriate
Pad. AUTO ZERO gives autorrratic,
instant zeroing of the instrument with-
out any manual adjustment, At the
touch of SPAN CHECK the stability of
the span reading can easily be verified
without use of a standard gas. Peri,rdic
recalibration with a standard teas is also
available by touching the STANDBY
pad,
FLASHING ALARM SIGNALS
Flashing symbols on the LCD screen
inform the operator of any irregularity,
One symbol signifies improper inser-
tion of the probe in the exhaust pipe
or a flow line leak during sampling,
Another shows that the probe is still
sampling exhaust when PURGE is acti-
vated. The filter alarm signals the need
for the filters to be changed. A flashing
question mark indicates that the read•
ing exceeds the measurement range and
is thus for reference only.
FLEXIBLE SAMPLE PROBE
The same sample probe may be used
for vehicles with either 4-stroke (4-
cycle) or 2-stroke (2-cycle) engines. The
probe tip is flexible to accommodate
bends in the exhaust pipe, An integral
clamp ensures correct and secure posi.
tioning in the tail pipe- The easily re-
placed pre-f(Iter removes dirt and oil
from the exhaust sample before it
enters 5 m sampling line. Finally, an
efficient metallic drain separator is
incorporated to rerrrove excessive
moisture before the sample enters the
analytical systarn.
SIMPLIFIED GAS CALIBRATION
Just touch STANDBY and apply a
standard gas at the span gas port on
the top. HC span calibration using
propane gas is easy with the MEXA-
534GE, Simply adjust the meter to
read half the propane concentration
marked on the standard gas container
for n-hexane equivalent calibration.

APPENDIX B

Potential Emissions Data Calculations
Total Petroleum Hydrocarbons & Benzene
The calculations are based on 99 percent removal efficiency given normal operating conditions with
proper maintenance and monitoring. Under these conditions, the expected emissions for benzene and total
petroleum hydrocarbons (TPH as N-Hexane) are estimated as follows:
TPH,: (9000 ppm) HC x 0.01 Eff x (86 lbs) Hexane x (80 ft3) scfm
lbmole min
x 3.7995E-6 (min) (lbmole) = 2.4 lb = 0.098b = 0.4tons
(day) (ppm) (fe) Day Hour Year
Benzene2: (4.5 ppm) Benzene x (78 lbs ) Benzene x (80 fe) scfm
lbmole min
x 3.7995E-6 (min) (lbmole) = 0.11 lb = 0.004 lb = 0.02 tons
(day) (ppm) (fe) Day Hour Year
1. TPH MW = 86 lbs/ lbmole (Hexane)
TPH worst -case concentration was reported at 9,000 ppm. Given 99% removal efficiency,
the expected air emissions for TPH is 90 ppm.
2. Benzene MW = 78 lbs/lbmole
Benzene comprises approximately 5% of gasoline product (worst -case). Based on the
reported concentration of TPH within the soil (9000 ppm), the expected benzene influent
from soil vapors is about 450 ppm. Given 99% removal, the air emission concentration
for benzene extracted from the soils is estimated at 4.5 ppm.
