1.10 INTRODUCTION
Gasoline impacted soils were discovered during the removal of three underground
tanks in November 1989 at the Pence Petroleum Company facilities at 901 East Truxtun
Avenue in Bakersfield, California. Subsequently, a series of assessment borings were
drilled at the site during several site visits. A gasoline' plume was defined centered at
the eastern end of the former tank cluster. The vertical extent of the plume was
determined to be approximately 120 feet below grade while laterally significant
contamination was interpreted to extend 25 to 30 feet from the plume's center,
although hydrocarbons were detected in borings beyond those limits. Published data
indicates first groundwater under the site at a depth of approximately 200 feet.
Remediation was initiated by AquaGeosciences, Inc. in October 1991 with the
installation of four vapor extraction and/or inlet wells, each screened through a section
of the impacted soil interval. The wells were eventually connected to a vapor
extraction system (VES) utilizing an internal combustion engine (IC) to provide the
motive power to pull vapors from the wells and which used the vapors as' fuel.
Catalytic converters provided air pollution control and supplemental propane fuel was
used as required in the latter stages of remediation. Additional vapor extraction/inlet
wells were installed In October 1993 to enhance the efficiency of the system and by
early 1994 decreasing influent concentrations and increased propane usage signaled
the end of the remediation process.
A confirmation boring was, drilled at the center of the most impacted area to a total
depth of 110 feet in May 1994. Samples were collected at five foot intervals and all
were chemically analyzed for BTEX and TPH as gasoline. Gasoline constituents were
detected in most samples, but at concentrations considerable reduced as compared
with pre-remediation levels. The analytical results were used to prepare risk analyses
for groundwater and human health (due to inhalation of potential vapors reaching the
surface) because of the hydrocarbons left in place. The results indicated minimal risks
and site closure was recommended in a Closure Report dated June 1994. This
recommendation was accepted by the Kern County Department of Environmental
Health Services, however additional analysis, particularly of the consequences of the
remaining TPH concentrations was requested. This report is a revised and expanded
copy of the original submitted addressing those concerns.
2.0 BACKGROUND
Three underground gasoline tanks (one 10,000 gallon and two 6,000 gallon
capacities) and an associated dispenser island were removed from the subject site in
November 1989. The tanks were located adjacent to one another elongated in an
east-west direction in the center of the property. Chemical analyses of preliminary
assessment soil samples which were collected beneath the tanks and dispenser
indicated very elevated gasoline concentrations centered at the east end of the central
and northernmost tanks (Table 1).

A site assessment by Associated Soils Analysis 1 was subsequently conducted
between July and November 1990. Four borings (82, 83, 83A and 84) were advanced
to a maximum depth of 120 feet below grade and selected samples from each boring
were chemically analyzed (Table 2). 8ecause of drilling difficulties, the contaminant
plume was not fully defined. Twin borings 83 (81.5 TO) and 83A (120 feet TO) located
near the center of the most impacted area at the east end of the former north tank
assessed the vertical extent of the contamination. Elevated gasoline concentrations
(maximum benzene - 370 ppm and TPH as gasoline - 24,000 ppm at a depth of 51
feet) were encountered from the surface to 80 feet, while low but detectable
concentrations persisted to total depth. Very low 8TEX and TPH (gasoline).
concentrations were reported in samples collected between 36 and 51 feet in boring
82 (TO 51.5 feet) drilled at the center of the former south tank location. 80ring 84 was

·
tit
sited at the southwest comer of the property approximately 65 feet from 83. Sampling
and field monitoring of hydrocarbon volatiles began at a depth of 60 feet and
continued to a total depth of 120 feet. Field evidence of hydrocarbons was noted
through this interval, but analysis of selected samples indicated very low
concentrations between 60 and 105 feet below which no hydrocarbons were detected.

AquaGeosciences, Inc. (AGI), in August 1991, continued the site characterization
activities and simultaneously initiated remediation by constructing vapor extraction
wells in the assessment boreholes. Four vapor extraction system (VES) wells were
constructed using two-inch PVC casing, each screened through a section of the
impacted soil interval. Selected soil samples were collected and analyzed (Table 3).
VE-1 was drilled at the east end of the former south tank to a depth of 105 feet.
Elevated photoionization (PID) readings were reported from the 5 feet to 90 feet. The
well was screened between 65 and 95 feet, an interval in which analysis of samples
indicated high gasoline concentrations (12,910-17,220 ppm TPH). VE-2 was placed at
the east end of the former center tank. Impacted soils were penetrated between 15

·
--
feet and and a total depth of 80 feet. The well was screened between 40 and 80 feet.
VE-3 was installed near the center of the former dispenser island north of the former
tank cluster. and was screened between 10 and 40 feet. The final well, VI-1, was
located 10 feet northeast of VE-3, a point approximately 20 feet from the plume's
center, however, field screening and analytical results from selected samples
demonstrated the presence of high gasoline concentrations (5105-15,000 ppm TPH-
gasoline) from 25 feet to a total depth of 70 feet. This well was designed to function
primarily as an air inlet well with the perforated interval between 25 to 65 feet.

Vapor extraction commenced under permit from the Kern County Air Pollution Control
District in August 1992 using a modified VW industrial liquid cooled internal
combustion engine equipped with exhaust emission catalysts. Fuel for the engine was
provided by the hydrocarbons drawn from the wells by the inductive action of the
engine itself. This system operated until mid 1993 when continued high influent
concentrations, lack of supplemental propane fuel usage and the presence of gasoline
condensate in the knockout chamber indicated the need for improving efficiency of the
system. The installation of three additional VES wells was proposed and
subsequently the wells were installed in October 1993. The wells were located
approximately 30 feet southwest (VI-4), southeast (VI-5) and northeast (VI-6) from the
center of the most impacted area at the east end of the former north and center tanks.
VI-4 was advanced to 96.5 feet and was screened between 50 and 95 feet; VI-5 was
5
·e
e
drilled to 41.5 feet and was screened between 10 and 40 feet, whereas VI-6 reached a
total depth of 81.5 feet and the perforated interval was placed between 30 and 80 feet.
Each wellhead was equipped with a valve allowing the well to be used for extraction
or as an inlet for outside air; the latter being the primary function. Selected samples
were collected for chemical analysis during drilling of these additional well (Table 4).
Elevated gasoline concentrations were detected partiéularly in the case of VI-5 (810-
5200 ppm TPH-gasoline) although levels notably of the BTEX components were
considerably lower than in previous sampling at the site reflecting remediation
activities and the location of the borings away from the core area of the plume.

By early 1994, the operation of the IC engine could not longer be continued without the
almost exclusive use of supplemental propane indicating a reduction of influent
concentrations. On May 18, 1994 a confirmation boring C-1 was drilled to a depth of

110 feet at a location at the east ends and between the former north and center tank,
the center of the plume. Samples were collected and analyzed from 5 foot intervals
throughout the length of the boring. Although elevated hydrogen flame ionization
(FID) readings were recorded, analytical results demonstrated a significant decrease
in gasoline concentrations, particularly in the BTEX constituents compared with pre-
remediation results (maximum benzene - 1.5 ppm a"nd TPH-gasoline - 3000 ppm).
These results were presented with an analysis of risks to groundwater resources and
an analysis of inhalation risks to people from vapors emanating upwards from the
impacted soil mass in a Closure Report dated June 1994. Both risks to groundwater
and human health were interpreted to be minimal. No further action was deemed
necessary and site closure was recommended. The Kern County Environmental
Health Services Department by letter dated June 27, 1994 accepted this
recommendation provided the YES system was dismantled and all wells were
properly abandoned. This has now been accomplished. Subsequently, due to
lingering concerns regarding the still elevated TPH concentrations remaining at the
site, additional analysis was requested. The following revision to the Closure Report

The site, known as Pence Petroleum Company, is located at 901 E. Truxtun Avenue, on
the southeast corner of East Truxtun and Beale Avenues in Bakersfield, California
(Exhibit 1). The property parcel number is APN 017-160-07-00-0.
The property is currently unoccupied and was formerly operated as Pence Automated
Fuels by the Pence Petroleum Company. Prior to 1986, the site was owned by Davies
Oil, Bakersfield, California, and was used as an automated card lock fueling station.
Exhibit 2 shows the former locations of the site facilities, as well as the former borings
and existing wells.
The property is situated to the south-southeast of downtown Bakersfield. Land use
surrounding the site is varied in nature ranging from Light and Service Industrial to
High Residential as indicated by the Metropolitan Bakersfield 2010 General Plan - East
Map (3-7-90, updated 10-14091). On three sides (north, west, and south) the site abuts
public streets (East Truxtun, Beale, and East 18th Street, respectively). To the east, at
985 East Truxtun, is Signet Hardware, Inc. Residential areas lie to the south and
southeast of the site.
4.0 SITE GEOLOGY
Soil borings at the site penetrated a sequence of unconsolidated sediments to a
maximum depth of 120 feet below grade. The unconsolidated soils are Recent non-
marine flood-plain fan deposits (California Division of Mines and Geology, 1964) 2.
The stratigraphic section consists of alternating dense to very dense silty sands and
sandy silts with interbedded clay and poorly graded sand. The soils moisture content
7
.
.
varies between dry to moist, predominately slightly moist.
No free standing ground water was encountered during the various field
investigations. Published data (Kern County Water Agency, 1991) 3 show that
groundwater occurs beneath the site at a depth between 200 to 250 feet (bsg) with a
gradient to the south and southwest. .
5.0 FIELD ACTIVITIES
AGI drilled one (1) confirmatory boring in the middle of the preexisting plume to show
that soil has been remediated to reasonable levels given the depth to groundwater at
this site. Boring C-1 was advanced to 110 feet at the location shown on Exhibit 2.
5.1 BORING METHODS
One (1) soil boring, C-1, was advanced using aCME 75 rig with a six inch diameter
hollow stem continuous flight auger in accordance with ASTM Method D-1452-80 for
soil investigations and sampling by auger borings. The augers were steam cleaned
prior to advancing the boring. The lithology and other pertinent data was recorded on
field boring logs in accordance with Method D 2488-84 for visual description and
identification of soils. Soil generated during the drilling process was placed on
Visquene at the site while waiting for analytical confirmation. Analytical results
indicate the cuttings were impacted so this soil will be remediated on site using
aeration and/or bioremediation. A cement slurry was used to abandon the borehole.
5.2 SOIL SAMPLING
Soil samples were collected through the auger in 2-inch diameter brass sleeves
driven in a split spoon sampler by a 140 pound hammer with a 30-inch drop in
accordance with ASTM Methods D1586-84 for split-barrel sampling of soil and D158"7-
83 for thin-walled tube sampling of soils. The brass sleeves and sampler were
washed in Alconox prior to each use.
Soil samples were taken at depths of 5 foot intervals to a total depth of 110 feet. The
blow counts, recovery, and lithology were recorded on field logs. Lithology was then
described by an experienced environmental geologist under the direct supervision of
a California Registered Geologist in accordance with ASTM procedure D2488-84
(Standard Practice for Description and Identification of Soils). One brass sleeve with
soil from each interval was sealed with teflon tape, capped, secured with duct tape,
labeled in accordance with EPA protocols, recorded on a Chain-of-Custody form,
placed in a cooler at 4° centigrade, and transported to Halcyon Laboratories, a
California Certified Laboratory with the Chain-of-Custody for the specified analyses.
Appendix C contains the boring log for C-1.

5.3 FIELD SCREENING OF SOIL SAMPLES
Soil samples were collected using three (3) six-inch brass tubes installed inside a
split-spoon sampler. The middle sample tube was immediately sealed and prepared
for transport and stored in an iced cooler upon collection. The bottom tube was used
for lithologic description and the top tube was used for field screening. The material
from the top tube was placed in a mason jar to approximately 50 percent capacity,
shaken, and stored for a period of 15 minutes. A standard headspace reading will be
collected at this time and noted on the boring log. Field screening was accomplished
using a photo-ionization detector (PID).
5.4 SOIL ANALYSIS
Twenty two (22) confirmation soil samples were sent to Halcyon Laboratories, a
California State Certified Laboratory in accordance with state guidelines and EPA
protocols. All samples were analyzed for Total Petroleum Hydrocarbons (TPH) as
gasoline and volatile aromatics (BTEX) using EPA Method 8015 modified and 8020,
respectively.
6.0 FINDINGS
On May 18, 1994, AGI advanced a confirmation boring, designated as C-1 (Exhibit 2),
to 110' below surface grade. ACME 75 hollow stem auger drilling rig operated by
Soils Engineering Inc. was used. The rig was positioned to the south of the VES unit,
approximately 4 feet from VE-3. Although field indicators of hydrocarbons (petroleum
odor and photo-ionization detector readings of cuttings) appeared high, lab analyses
indicate that the hydrocarbons concentrations present in the soil in the central area of
the plume have been greatly diminished. Table 5 includes analytical results for C-1.
Appendix D contains laboratory reports with the chain of custody.

7.0 RISK ANALYSIS - GROUNDWATER
The primary objective of the underground tank regulations is protection of groundwater
resources. The State of California through the Department of Health Services and the
State Water Resources Control Board developed the Leaking Underground RJel Tank
(LLJFT) Manual 4 to provide guidelines to regulatory agencies and other interested
parties concerned with investigation, risk assessment and cleanup of underground
tank related leaks. That document presents two methods to determine if soil
contamination can be left in place without threatening groundwater. The simplest is a
leaching potential analysis for gasoline which evaluates those site characteristics
which influence the downward migration of the fuel components BTXE and
10
e
II
TPH(gasoline) such as; depth to' groundwater, precipitation, soil lithology and the
presence of conduits, both manmade and natural (fractures), to determine the
allowable BTXE and TPH concentrations which can be left in place without threatening
groundwater. Using this approach the Pence Petroleum site was determined to fall into
the low leaching potential category, however, several samples from the confirmation
Boring C-1 exceeded the stipulated maximum allowable TPH(gasoline) and Brr/XIE
levels which for the low category are 1000 ppm and 1/50/50/50 ppm, respectively
(Table 6).
For those sites with a value above allowable levels, further analysis using the General
Risk Appraisal is recommended. This is a more sophisticated approach adapted from
two computer simulations to estimate the concentrations of BTEX components which
can be left in place without endangering groundwater. This method also considers the
physical characteristics of the site as well as environmental fate and chemistry data for
BTEX. The first step is use of a questionnaire to determine whether site conditions do
not present a greater risk to groundwater than those on which the models are based.
An environmental fate worksheet is then completed for each of the BTEX components
(Table 8, 9, 10, & 11). The concentration detected in samples at each successive five
foot interval is added to the sum of the previous concentrations for the total vertical
distance of the plume. The sum at each interval is compared to Acceptable
Cumulative Contamination Levels provided in Appendix E for each aromatic
component to determine if remediation was successful. These tables show distance to
groundwater from the contaminated mass on the vertical axis and annual rainfall on
the horizontal axis.
Use of the General Risk Appraisal for Pence Petroleum appears to be suitable based
on the preponderance of "NO" answers on the checklist (Table 7). Worksheets for the
confirmation boring were then completed to evaluate residual risks to groundwater. A
depth to groundwater of 200 feet was used in the analysis based on Kern County
Water Agency maps.
A complete profile of the present distribution of gasoline hydrocarbons at the center of
the impacted soil mass was provided by analysis of samples collected during the
drilling of confirmation Boring C-1. Samples at every 5 foot interval between 5 and 110
feet were chemically analyzed. At no depth interval were cumulative concentrations of
any BTEX components found to be in excess of Acceptable Levels (Tables 8, 9, 10, &
11). On the basis of this analysis, it can be concluded that the hydrocarbon
concentrations still present at the site do not constitute a threat to groundwater
resources.
Another approach to evaluate the potential for fuel hydrocarbon contaminants to
migrate to the deep groundwater aquifer is modeled after a fate and transport analysis
used by Environmental Science and Engineering, Inc. at a similar site in Kern County5.
This report was provided AGI by the KCDEHS as an acceptable methodology.

It can be assumed that 5 years after the removal any source' of fuel leaks and after a
period of vapor extraction, downward migration of liquid gasoline hydrocarbons at the
Pence site has essentially ceased. As a finite quantity of bulk hydrocarbons spread
vertically and laterally in the soil column driven primarily by gravity they are eventually
transferred to a state of residual saturation, that is, they are immobilized by adsorptive '
and capillary forces acting between the hydrocarbons and the mineral grains of the
soil. Although some diffusion of volatile fractions in the interconnected pore spaces
will occur, further downward movement will be dependent on the action of any
infiltrating water passing through the contaminated soil mass, dissolving a portion of
the adsorbed hydrocarbons, and carrying them downward. Other than possible
manmade sources (irrigation water), precipitation provides the hydraulic loading which
drives this process. The annual amount of soil water percolating downward can
roughly be estimated by the water balance equation (Dragun, 1988) 6:
Q=P-R-ET-dW
Where:
Q = Percolation rate
P = Annual Precipitation
ET = Annual Evapotranspiration
dW = Change in storage in the unsaturated zone
Assuming that dW and R are negligible:
Q=P-ET
For Bakersfield average annual rainfall is 5.74 inches or 14.58 cm (Kern County Water
Agency, 1993). Average annual evaporation as measured at three Kern County
stations is 62.46 inches or 158.65 cm {Kern County Water Agency, 1993}.
Evapotranspiration is estimated using a measured Class A pan evaporation rate in the
following formula (EPA, 1988)7.
ET = EVAP{Cet){Cveg)
Where:
EVAP = evaporation rate
Cet = Correction factor for converting evaporation rates to
evapotranspiration rates from turf grass.
Cveg = Correction factor for converting evapotranspiration from turf
grass to evapotranspiration from other vegetative cover
types.
Values for Cet (0.5) and Cveg (0.6) were obtained from the EPA (1988) and are based
on moderate winds of 10 miles per hour and relative humidity of less than 60 percent.
12
e
-
Therefore:
ET = (158.65 cm/yr)(0.5)(0.6) = 47.60 cm/yr
By substituting values derived for P and ET into the equation for 0, the percolation rate
for the site is calculated:
0= 14.58 cm/yr - 47.60 cm/yr = - 33.02 cm/yr
The negative result indicates no significant percolation of water occurs at the site and
therefore, hydrocarbon constituents are not expected to leach to groundwater.
To insure a conservative analysis, a percolation rate of 1 crn/yr is assumed (this would
require that occasionally annual rainfall totals reach 19.13 in/yr or 48.60 cm/yr). Based
on the site characterization information, approximately 80 feet separate the water table
from the base of the contaminant plume, and therefore, at a 1 cm/yr percolation rate,
over 2400 years would be required for dissolved hydrocarbons to reach groundwater.
To continue the analysis assuming hydrocarbons do occasionally reach groundwater,
the concentration of constituents of concern in percolating water can be estimated by
using the equilibrium solubilty of the constituent (Co) as determined in the following
equation:
Co = Csoil/(Koe)(foe)
Where:
Co = Equilibrium solubilty of the constituent (mg/L)
Csoil = Concentration of the constituent in soil (mg/kg)
Koe = Soil water partition coefficient
foe = Fraction of organic carbon in soil
According to Dragun (1988), subsoils typically possess organic carbon contents of less
than 0.1 percent and therefore, foe of 0.1 percent is used in the calculation. Generally
the presence of organic material in the soil promotes hydrocarbon adsorption. The
BTEX concentrations used are the mean value derived from all samples in which a
particular constituent was detected in Boring C-1, as shown in the following Table.
Constituent Detection Frequency Range Mean Standard Deviation
Benzene 13/22 .005-1.5 .54 .41
Toluene 19/22 .005-3.3 1.4 1.00
Ethylbenzene 15/22 .005-2.9 1.3 .92
Xylenes 21 /22 .005-12 5.2 4.3
The values use of Koc are derived from the EPA, 19868. Estimated equilibrium water
concentration for the BTEX constituents calculated using the above formula are listed
in the following Table.

Benzene .54 83 6.5
Toluene 1.4 300 4.7
Ethylbenzene 1.3 1100 1.2
Xylenes 5.2 240 21.7
The loading rate or intensity with which bulk hydrocarbons are released from a liquid
to dissolved state can be estimated by the following formula (EPA, 1988):
Lc = (O)(A)(Co)
Where:
Lc = Constituent loading rate (mg/yr)
0= Percolation rate (cm/yr)
A = Area of contamination (m2)
Co = Equilibrium solubilty of the constituent
The area of significant contamination based on the assessment findings has a
diameter of approximately 60 feet which equates to an area of 2826 ft2 or 2.6 x 106
cm2. A value of 1 cm/yr is used for percolation rate (0). The loading rate calculated for
each BTEX constituent is listed in the following Table.
Constituent Co (mg/L) Lc (mg/yr)
Benzene 6.5 1.7 x 104
Toluene 4.7 1.2 x 104
Ethylbenzene 1.2 3.1 x 103
Xylenes 21.7 5.6 x 104
The estimated loading rates for BTEX are very low and demonstrate that leaching to
groundwater is insignificant.
To estimate future concentrations of BTEX in groundwater under the Pence site, the
volumetric flow rate of groundwater as calculated using Darcy's equation:
o = -KiA
Where:
o = Flow rate (Uyr)
K = Hydraulic conductivity (mIday)
i = Hydraulic gradient (m/m)
A - Cross sectional area of aquifer through which flow occurs (m2)
14
-
-
A hydraulic conductivity of 10-1. m/sec or 86.4 m/day was selected. According to Fetter·9
this is representative for well sorted sands. A gradient of .004 ft/ft was used based on
the average gradient between Bakersfield and Arvin as depicted on Kern County
Water Agency maps (1993). The thickness of the impacted upper portion of the aquifer
was assumed to be 32.8 feet or 10 meters and the width of the impacted zone 60 feet
or 18 meters. A flow rate of 2.3 x 107 Uyr was calculated.
Dividing loading rates for the BTEX constituents by the flow rate yields an estimated
maximum concentration as shown on the next Table.

Regarding the consequences of leaving TPH as gasoline in the ranges indicated by
the Boring C-1 sample analyses, to the knowledge of AGI there are currently no
models which are applicable to TPH alone. The fate and transport analysis presented
is based on the BTEX components alone because these are relatively simple single
compounds, as compared with gasoline which is a mixture of numerous compounds.
BTEX constituents are also the most soluble and mobile components of gasoline, as
well as posing the highest health risks. Therefore, they they are the most likely
components of gasoline to reach the deep groundwater aquifer. If it can be
demonstrated, as AGI believes it has, that these constituents pose little risk, it can also
be assumed the less mobile TPH constituents do not endanger groundwater
resources as well.
However, to evaluate potential risks associated with TPH as gasoline, a mean TPH
concentration of 882 mg/kg was calculated from the analytical results from the Boring
C-1 samples. Concentrations ranged from 1.2 to 3000 mg/kg. This value was used to
calculate equilibrium water solubilty concentration (Co), groundwater loading rate (Lc)
and maximum groundwater concentration as was done for BTEX. It should be restated
that this is based on a percolation rate of 1 cm/yr which is predicated on an annual
rainfall for the area which seldom occurs. Another factor not considered in thes,e
models is the beneficial effects of biodegradation due to the action of aerobic and
anaerobic bacteria through time. The calculations result in the following findings:
Co = 10, 626 mg/L
Lc = 2.7 X 107 mg/yr
Estimated Maximum Concentration = 1.2 mg/L

8.0 RISK ANALYSIS - SURFACE ENVIRONMENT
Risks to people and the surface environment from vapors migrating upward from the
contaminated soil masses are also considered to be very low. The affected area at the
former tank location will be overlain by asphalt paving used for parking space for the
business to the east. If left in this condition, little to nO risk to human receptors would
exist. The following Risk Assessment for the Surface Environment is performed in the
unlikely event that a building would be placed on this vacant area.
An effort has been made to evaluate health risks due to exposure to benzene
volatilizing from the soil and entering a fictitious building from the plume. Benzene
was used because of its high volatility and known carcinogenic properties, it is
considered to pose the greatest health risks. The highest concentration reported from
the confirmation boring C-1 was 1.5 ppm which was detected at a depth of 55 feet.
This value was used in the calculations. Laboratory determined values for soil
properties required for the analysis are not available. Assuming a sandy
unconsolidated sediment type with a low moisture content, the following parameters
were estimated:
Porosity .35
Bulk Density 2.0
Moisture Content .15
The approach used for the risk assessment is based in part on the methods and logic
presented in the California Site Mitigation Tree Manuapo and a report by Chemrisk11
submitted to the Orange County Health Care Agency and made available as an
example of a state of the art risk assessment. The steps followed and conclusions of
this analysis are outlined below followed by a complete discussion and the
calculations.
8.1 SUMMARY OF RISK ANALYSIS FOR BENZENE
The first step in the risk evaluation process is the calculation of the steady state flux of
benzene through the soil matrix assuming a non-diminishing source at some distance
below the ground level. This determination requires a knowledge of benzene's ,
coefficients of diffusion in air and through the soil as well as the vapor phase
concentration of the compound at the source.
Knowing the vapor phase flux through the soil, the volume of air within the building, a
ventilation rate and assuming a leakage rate through a structure's foundation, a
benzene vapor concentration within a building can be predicted. Then, taking a worst
case scenario of a person working their entire 45 year occupational lifetime at the
business, a lifetime average daily dose (LAD D) received can be derived.
16
e
e
Values of indoor vapor concentrations and LADDs can be compared to regulatory
guidelines to evaluate degree of exposure and risks. In this instance, the indoor
concentration of benzene was calculated to be 2.1 X 10-8 mg/m3. The Department of
Health Services Applied Action Level for benzene in ambient air is 3.2 X 10-3 mg/m3.
The air concentration for lifetime cancer risk due to benzene exposure 6.6 X 10-4
mg/m3 can also be used. Based on an individual who worked at the site for 45 years, a
LADD of 1.0 X 10-9 mg/kg-day was calculated. This result can be compared to 3.0 X
10-4 mg/kg-day which is considered to result in a 1 and 100,000 excess cancer risk
under DHS Proposition 65 guidelines. In all cases, calculated values are well below
established guidelines.
The potential for carcinogenic health effects can also be evaluated by multiplying the
lifetime benzene exposure (inhaled volume times concentration) with an "adjusted
potency factor" (USEP A, 1988b)13 to derive a carcinogenic risk associated with a
specific exposure to benzene. In general, regulatory agencies have found that a risk
in excess of 1 and 1 million is acceptable. In some instances risks of 1 in 100,000 are
used in setting environmental standards. At Pence Petroleum a risk of 3.86 X 10-11 was
derived, well below the 1 in 1,000,000 criteria.
In conclusion, based on this risk assessment, no significant health hazards related to
the gasoline contamination at the Pence Petroleum site are believed to exist. The
contamination does not encroach on any proximal building and the site will be sealed
at the surface with asphalt paving.
8.2 RISK ASSESSMENT FOR BENZENE
STEADY STATE VAPOR FLUX
The first step in determining the benzene exposure to occupants is the calculation of
the rate of emission of the chemical from the soil. This rate is influenced by such
factors as the degree of partitioning of benzene between vapor, soluble and non-
aqueous phases, the rate and degree of movement of the various phases through the
soil, soil properties, and environmental factors such as temperature, moisture and
surface conditions. The general approach used, is to take the dominant transport
mechanism, in this case vapor diffusion, and model the process. The model used is
based on one developed to predict emissions from landfills by Thibodeaux and
Hwang14. It assumes steady-state fluxes for a non-diminishing source at a specific
depth below the ground surface. The applicable equations are:

BENZENE CONCENTRATION IN INDOOR AIR
Knowing the vapor flux through the soil, an estimate can be made of the concentration
of benzene in the indoor air of the fictitious building which might contains a volume of
approximately 8600 ft3 (244 m3) given the space available. Benzene reaching the
surface under the structure may enter the building through openings in the floor, for
example, cracks, joints and loose fitting pipes. The ratio of leakage to total floor area
in the average California home is 2 - 10 cm2/m2 of floor area (Grimsrud et al )17.
Commercial buildings built on concrete slabs would experience less leakage than
residences with crawl spaces, therefore, the lower value of 2 cm2/m2 is used in this
analysis.
The ventilation rate for the building is based on studies of Fisk et aP8. They estimated
that the average air exchange rate for residences at 0.5 - 0.9 air changes per hour.
The most conservative low end value 0.5 is used. A retail business with numerous
customers entering and leaving and equipped with modern ventilation systems would
experience much higher exchange rates.
The concentration of benzene in the indoor air is predicted by the equation:

RISK BY EXPOSURE
In order to estimate the health risks associated with exposure to benzene, a very
conservative approach was used based on a individual working at the business for an
entire occupational lifetime of 45 years, 5 days a week and 50 weeks a year with an
inhalation rate of 10 m3/hour.
Total lifetime inhaled volume = 1.13 X 105 m3
Average daily volume = 4.4 m3/day
Exposure is the product of contaminant concentration (Cb) and the air volume
breathed calculated by the following equation:

Risk associated with a specific exposure
Benzene adjusted potency factor [mg/lifetime exposure]-1 =
1.63 X 10-8 per USEPA 1988 - derived from
epidemological studies on cancer induced leukemia.
Exposure = inhaled volume M3 X concentration
R = (1.63 X 10-8)(1.13 X 105)(2.1X 10 -8) = 3.86X 1011
9.0 RECOMMENDATIONS
Based on the information obtained and analyzed from confirmation boring C-1, risks to
groundwater resources and public health are considered to be extremely low. No
further assessment or remediation of the site is deemed necessary and site closure is
recommended.
10.0 LIMITATIONS
AquaGeosciences, Inc. performed this investigation in accordance with generally
accepted standards of care which exists in California at this time. It should be
recognized that definition and evaluation of geologic conditions is a difficult and
inexact science. Judgments leading to conclusions and recommendations are
generally made with limited knowledge of the subsurface conditions present. No
warranty expressed of implied, is made.

(
.ae following table was designed to permit estimating the
concentrations of TPH and BTX&E that can be left in place without
threatening ground water. Three levels of TPH and BTX&E
concentrations were derived (from modeling) fçr sites which fall into
categories of low, medium or high leaching potential. To use the
table, find the appropriate description for each of the features.
Score each feature using the weighting system shown at the top of
each 'column. Sum the points for each column and total them. Match
the total points to the allowable BTX&E and TPH levels.

1.0 INTRODUCTION
1.1 Purpose
Based upon propane usage for the Vapor Extraction System, AGI recommends the
following course of action:
1. Advance confirmation boring to establish the concentrations of residual
gasoline fuel remaining throughout the plume.
2. Prepare a contaminant fate transport analysis and a health risk assessment
prior to requesting regulatory closure of the site.
1.2 Scope of Work
The scope of services described in the Workplan include:
*
Locating underground utilities from as-built drawings (if available) as well
as Underground Service Alert (U.S.A.); .
*
Advancing one (1) soil boring in the vicinity of the former gasoline storage
tanks and associated underground piping;
*
The one boring will be advanced to a depth of 110 feet, or ten feet of clean
(non-detect) soil, or until encountering groundwater;
*
Steam cleaning of all drilling and sampling equipment prior to the boring to
minimize cross-contamination;
.
Collecting soil samples at depths to be evaluated in the field. Initially,
samples will be collected at approximately five (5) foot intervals beginning
at five (feet) feet below ground surface (bgs) and continuing until total
depth. The samples will be collected using a standard California split-
spoon sampler equipped with brass tubes, which have been steam
cleaned prior to use. These samples will be field screened and selected
samples will be submitted for chemical analyses;
*
Field Screening will be accomplished using a photo-ionization detector
(PID) equipped with a 10.0 eV lamp or a flame-ionizing detector (FID). Soil
samples will be placed in mason jars to approximately 50% capacity,
shaken, and let stand for approximately 15 minutes. A standard
he~dspace reading will then be collected;
2 of 19
e
e
*
Soil samples for chemical analyses will be collected in brass tubes and
sealed with teflon tape, end caps and duct tape. The sealed tubes will be
placed in a cooler at 4° centigrade for transport to Halcyon, a State of
California DHS certified laboratory, under chain-of-custody protocol;
*
Analysis of approximately 22 soil samples for Total Petroleum
Hydrocarbons as gasoline and volatile aromatics using EPA Methods 8015
modified and 5030/8020, respectively;
*
Prepare field boring logs with appropriate lithology descriptions, blow
counts, PID readings, etc. in accordance with ASTM Methodology and the
Unified Soils Classification System;
*
Prepare a Risk Assessment to assess whether soil contamination may be
left in place without threatening groundwater. AGI proposes using the
SESOll Model described in the leaking Underground Fuel Tank (lUFT)
Field Manual issued by the State of California lUFT Task Force. SESOll
is a mathematical model which simulates the long-term environmental fate
of pollutants in the unsaturated zone. It can simulate movements of
pollutants introduced into the vadose zone and predict the quantity of
pollutants which may migrate to groundwater. The SESOll simulation can
also be used to evaluate emissiøn rates at the soil surface of the site. Input
parameters are similar to those used to determine groundwater risk.
*
AGI will prepare a Health Risk Assessment for benzene, a volatile aromatic
constituent in gasoline which poses the most concern from a human health
standpoint. The Health Risk Assessment will be conducted in accordance
with the methods described in the Toxic Air Pollutant Source Assessment
Manual for California Air Pollution Control District Permits (known as the
CAPCOA Manuãl)._ Cancer risk for benzene is evaluated using the
emission rates calculated from the SESOll Model and the resultant
ambient air concentrations from the CAPCOA guidelines.
*
Prepare a written report summarizing the results of the investigation
including conclusions and recommendations. Additionally, a summary of .
the Risk Assessment which will include all input assumptions and
variables used in the calculations will be presented. The report will be
certified by a California Règistered Geologist. It should be noted that
preparation of this assessment and its subsequent certification by a
registered geologist does not automatically assure approval for closure,
but provides a quantitative evaluation of the risk to human health for further
evaluation by the State.

1.3 Schedule
AquaGeosciences, Inc. anticipates beginning work described herein within one week
upon approval from the County and authorization to proceed from Mr. Robb Pence.
The soil boring can be drilled and sampled in approximately two working days. The
analytical data will be reported within two weeks of field work completion and the
report will be completed within one month after receipt of the analytical results.
2.0 BACKGROUND
2.1 Property Description
The site, known as Pence Petroleum Company, is located at 901 E. Truxtun Avenue,
on the southeast corner of East Truxtun and Beale Avenues in Bakersfield, California
(Exhibit 1). The property parcel number is APN 017-160-07-00-0.
The property is currently unoccupied and was formerly operated as Pence Automated
Fuels by the Pence Petroleum Company. Prior to 1986, the site was owned by Davies
Oil, Bakersfield, California, and was used as an automated cardlock fueling station.
Exhibit 2 shows the former locations of the site facilities, as well as the former borings
and existing wells.
Positioned to the south-southeast of downtown Bakersfield, land use surrounding the
site is varied in nature ranging from Light and Service Industrial to High Residential as
indicated by the Metropolitan Bakersfield 2010 General Plan - East Map (3-7-90,
updated 10-14091). On three sides (north, west, and south) the site abuts public
streets (East Truxtun, Beale, and East 18th Street, respectively). To the east, at 985
East Truxtun, is Signet Hardware, Inc. Residential areas lie to the south and southeast
of the site.
2.2 Project History
In 1986 Pence Petroleum purchased the site from Davies Oil of Bakersfield. On
November 1, 1989, two (2) 6,000-gallon underground gasoline storage tanks, one (1)
10,000-gallon underground gasoline storage tank, one dispenser island and
associated product lines were removed from Pence Petroleum's Automated Fuels
Card lock. Soil samples were collected from 2 and 6 feet beneath the former tanks at
the time of their removal. Table 1 summarizes the resu'ts of the laboratory analyses of
the soil samples reported in the Associated Soils 'Analysis, Inc., Site Assessment
Study of December 28, 1990, on file with the County.

Non-Detected
The laboratory results indicated that the soil was impacted with petroleum fuel, with the
highest concentrations of petroleum constituents detected at the eastern ends of the .
former tanks. Based upon these results, on March 2, 1990 the County requested a site
characterization to assess the extent of impacted soil.
Subsequent to the request, Associated Soils Analysis Inc. (ASA) advanced four soil
borings to a maximum depth of 120 feet below surface grade (bsg). Boring B-3 was
advanced in the vicinity of the former product line, believed to have originated the
release, and "detected a maximum concentration of total petroleum hydrocarbons as
gasoline (TPHg) of 24,000 mglkg at a depth of 50 feet (bsg). B-3 was terminated at a
depth of 80 feet (bsg) with TPHg concentrations of 4,700 mglkg. Boring B-3A,
advanced ten feet to the west of B-3, detected various concentrations of TPHg ranging
between non detect to 0.62 between a depth of 90 to 120 feet (bsg). Chemical
analyses of these borings are summarized in Table 2 and reported in the Associated
Soils Analysis, Inc., Site Assessment Study of December 28, 1990, on file with the
County.

The Phase I assessment work performed by ASA did not delineate the vertical limit of
hydrocarbon impacted soil beneath the probable product line release, nor was the
study able to define the lateral limits of the plume towards the north, east, or south of
the site. The- County requested an additional investigation to assess the lateral and
vertical extent of impacted soil.
In August, 1991 AquaGeosciences, Inc. (AGI) advanced four borings in compliance
with the County's request and completed the borings as vapor extraction/inlet wells.
The borings were advanced to varying depths ranging between 40 to 105 feet (bsg).
Table 3 summarizes the laboratory analyses of select soil samples collected from the
soil borings.

Elevated concentrations of TPHg were encountered to a depth of approximately 100
feet (bsg) in boring VE-1. The extraction well borings were positioned within the ..
vicinity of highest concentrations of soil contamination and completed with 30 to 40
feet of screen over intervals selected on the basis of field screening results to initiate a
son vapor extraction remediation program. An internal combustion engine was
manifolded to the extraction wells to extract and destroy the hydrocarbons contained in
the soil vapor.
AGI recommended the installation of additional air/vapor inlet wells to enhance
recovery of hydrocarbon vapors in the soil. On October 13 and 14, 1993, AGI
advanced three borings and completed the borings as vapor inlet wells. The
analytical results are listed below in Table 4. These inlet wells were designed to
sweep contaminants toward the present vapor extraction wells.

From October 15, 1993 through December, 1993, the machine ran almost exclusively
on processed -soil vapors and required very little supplemental propane. Beginning in
early December, 1993 propane usage increased dramatically indicating that the
concentration of the soil vapors had decreased. At this time the machine was shut
down for a period of one week to allow soil vapors to reaccumulate. The machine was
then restarted. Propane use was low for one day and then increased dramatically.
This c~ling ~s conducted three times from December, 1993 through January., 1994, /'
each time propane use wa xceedingly high; therefor .. inion that soil ..,/
por concentrations have decreased to a concentration that warrants a confirmatory
sóTI boring.
"""'--
The following sections detail AGI's workplan for this confirmatory sampling and
potential request for site closure.
8 of 19
a,
e
3.0 WORKPLAN
AquaGeosciences, Inc. proposes to assess and evaluate the remediation by vapor
extraction of gasoline and BTEX impacted soil at the Pence site toward obtaining final
closure. The proposed confirmatory sampling program is designed to meet the
closure requirements of the Kern County Environmental Health Services (KCEHS)
and to address any remaining public health concerns by conducting a Health Risk
Assessment with data derived from a site specific calibrated SESOIL model of surface
emission/vadose diffusion/and groundwater transport of the primary constituent of
concern, which is benzene.
3.1 Soil Boring Depths and Locations
One (1) soil borings will be advanced to a depth of approximately 110 feet. Soil
samples will be collected at five (5) foot intervals beginning at five (5) feet and
continuing to a proposed depth of 110 feet. Should field screening indicate the
presence of hydrocarbons, drilling will continue until groundwater is encountered or,
ten feet of unimpacted soil is detected.
The proposed locations are shown on Exhibit 2. The location has been chosen to
provide roughly continuous hydrocarbon concentration data in the area where pre-
remediation concentrations were the highest. Confirmation Boring C-1 will be
centrally located in the impacted soil plume between boring VE-1 and B-3. The
highest concentrations of petroleum constituents were detected at these locations
during the initial investigations.
4.0 METHODS
The following sections will describe in detail the methods to be employed in
implementing this workplan. -
4.1 Boring Methods
The borings will be advanced using aCME 75 rig, or equivalent, with a six inch or
larger diameter hollow stem continuous flight auger in accordance with ASTM Method
D 1452-80 for soil investigations and sampling by auger borings. The augers will be
steam cleaned prior to drilling each boring. The lithology and other pertinent data will
be recorded on a field boring log in accordance with Method D 2488-84 for visual
description and identification of soils.
9 of 19
(
.
-
Cuttings and other spoil from the borings will be placed in appropriate D.C.T. approved.
55-gallon drums until verified, with analytical results, whether or not the soil is
contaminated. If the material is contaminated, a written plan will be submitted by the
facility operator to the County for their approval before treatment and/or disposal
occurs. Disposal will be the responsibility of the Facility operator and will occur within
90 days of completion of drilling. /
Backfilling of the boring will be accomplished by pouring a cementlbentonite slurry. If
contaminants are not found or suspected in this boring, backfilling will take place by
placing native soil into the borehole and capping with a cement/bentonite plug.
4.2 Soil Sampling
Soil samples will be collected through the auger in 2-inch diameter brass sleeves
driven in a split spoon sampler by a 140 pound hammer with a 30-inch drop in
accordance with ASTM Methods 01586-84 for split-barrel sampling of soil and 01587-
83 for thin-walled tube sampling of soils. The brass sleeves and sampler will be steam
cleaned prior to each use.
Soil samples will be driven at depths of 5 foot intervals in each boring to a total depth
of 110 feet. The blow counts, recovery, and lithology will be recorded on the field logs.
Lithology will be described by an experienced environmental geologist under the
direct supervision of a California Registered Geologist in accordance with ASTM
procedure 02488-84 (Standard Practice for Description and Identification of Soils).
One brass sleeve with soil from each interval will be sealed with teflon tape, capped,
secured with duct tape, labeled in accordance with EPA protocols, recorded on a
chain-of-custody form, placed in a cooler at 4° centigrade or less, and transported to a
California Certified Laboratory with the chain-of-custody for the specified analyses.
4.3 Field Screening of SoB Samples
Soil samples will be collected using three six-inch brass tubes installed inside a split-
spoon samplér. The middle sample tube will be immediately sealed and prepared for
transport, and stored in an iced ceeler upon collection. The bottom tube will be used
for lithologic description, and the top tube will be used for field screening. The material
from the top tube will be placed in a mason jar to approximately 50 percent capacity,
shaken, and stored for a period of 15 minutes. A standard headspace reading will be
collected at this time and noted on the boring log. Field screening will be
accomplished using a photo-ionization detector (PID). Additionally, on-site chemical
analyses, using an SRI Instruments Gas Chromatograph (GC) in AGI's Mobile
Laboratory, will be performed during field operations.
1 0 of 1 9
e
-
4.4 Soil Analyses
Approximately twenty two (22) soil samples will be analyzed by Halcyon laboratories,
a California State Certified laboratory in accordance with state guidelines and EPA
protocols. The number of samples analyzed will be determined by the total depth of
the boring; however, a sample of each five (5) foot interval will be submitted for
analysis.
The samples will be analyzed for fuel hydrocarbons as gasoline and volatile aromatics
using EPA methods 8015 Modified and 5030/8020, respectively. The detection limits
for TPH as gasoline will be 0.5 mg/kg and for BTEX, 0.005 mg/kg.
5.0 HEALTH RISK ASSESSMENT
Once the remnant gasoline concentrations have been evaluated, a Health Risk
Assessment will be conducted to demonstrate the residual levels that may be left in
place without significant risk to human health or the environment. The Health Risk
Assessment will be performed according to the methods described in Sections 2 and 3
of the October 1, 1987 draft of the Toxic Air Pollutant Source Assessment Manual for
California Air Pollution Control District Permits (known as the CAPCOA Manual). The
objective is to demonstrate that the residually impacted soil may be left in place.
Therefore, the assessment will focus on exposures due to non-inhalation pathways,
such as soil ingestion, as well as, surface water and groundwater ingestion. The
inhalation exposure due to the residual gasoline fuel remaining is expected to be
minuscule and need not be pursued beyond a screening level unless initial estimates
indicate a substantial risk from this exposure pathway.
AGI proposes using the SESOll Model described in the leaking Underground Fuel
Tank (lUFT) Field Manual issued by the State of California lUFT Task Force. SESOIl
is a mathematical model whiçh simulates the long-term environmental fate and
transport of pollutants in the unsaturated (vadose) zone. It can simulate movements of
pollutants introduced into the vadose zone and predict the amount of pollutants which
will enter the -groundwater. The SESOll model can also be used to simulate emission
rates at the surface of the site. Input parameters are similar to those used to determine
groundwater.
6.0 CLEANUP TARGET CONCENTRATIONS
Cleanup target concentrations for gasoline and purgeable aromatics in soil are 1000
part per million (ppm) for TPHg and 1.0 ppm for BTEX with laboratory detection limits
of 0.5 ppm TPHd and 0.005 ppm BTEX.

,r.-- 7.0 REPORT OF FINDINGS
A report of findings will be prepared which will detail field activities, analytical results,
discussion of analytical results, conclusions, and recommendations. The report will
also include a summary of the Health Risk Assessment which will contain all input
parameters, assumptions and variables used in the calculations. The report of
findings will recommend what further action, if necessary, may be required. If
additional work is warranted, the scope of the additional work will be specified in the
report. The report of findings will be certified by a California Registered Geologist.
8.0 SITE ABANDONMENT PROCEDURES
Abandonment of operations at the subject site requires the removal of surface
facilities, as well as the destruction and/or cementation of all vapor extraction and inlet
wells, to include the following points:
*
Piping will be disconnected from the Vapor Extraction System and
well heads;
*
The Vapor Extraction machine and piping will be loaded onto a trailer and
removed from the site;
*
Upon approval from the County, the Vapor Extraction wells (VE-1 through VE-3)
and Vapor Inlet wells (VI-4 throug~I-6) will be destroyed by removing the well
head extensions and backfilling the casing and screen from total depth to
surface~rade with neat cement.
9.0
QUALITY ASSURANCE PLAN
This section describes field and--analytical quality-assurance procedures to be
followed during the investigation and remediation.
9.1 Sample Collection and Handling Protocol
Proper soil sample collection and handling are essential to assure quality of data
obtained from a sample. Each soil sample, therefore, will be collected in a brass tube,
properly preserved for the intended analysis, and analyzed within the permissible
holding time. Protocol to be applied in this project is described in Section 4.
9.2 Sample Identification and Chain-of-Custody Protocol
Sample identification and chain-of-custody procedures are designed to assure sample
quality and to document sample possession from the time of collection to the time of its
ultimate disposal. The container for each sample submitted for analysis will have a
12 of 19
e
e
~ -',
label affixed with the identifying number or the number will be inscribed directly on the
container. Additional information, such as, location, the depth of collection, sampler,
and date and time of collection will be included on the label.
The analytical laboratory will assign a separate sample number unique to that sample
for internal sample coordination and identification. A description of the sample
including the sample number and other pertinent information regarding its collection
and/or geologic significance will be written in field notes and/or a geologic boring log
being prepared by the site geologist. These field documents will be kept in a
permanent project file. All samples will be analyzed by a State certified laboratory for
the requested parameters.
A properly completed chain-of-custody form will be submitted to the analytical
laboratory along with the sample(s) and the laboratory's assigned number will be
properly entered on the form. A quality control officer at the laboratory will verify
integrity of samples submitted, proper sample volume, correctness of containers used,
and properly executed chain-of-custody form. Pertinent information will be entered
into a log book kept by the laboratory.
9.3 Analytical Quality Assurance
In addition to routine calibration of analytical instruments with standards and
blanks, the analyst is required to run duplicates and spikes on 10 percent of analyses
to assure an added measure of reliability and precision. Accuracy is verified through
the following:
1. U.S. EPA and State certification of results;
2. Participation in inter-laboratory round robin program;
3. "Blind" samples are submitted for analysis by the quality control officer on
a weekly basis. These are prepared from National Bureau of Standards
specifications of EPA reference standards;
4. Verification of results with an alternative method.
10.0 SITE SAFETY PLAN
Appendix A contains a Site Safety Plan which complies with Worker Right to
Know Regulations and CCR Title 26.

APPENDIX A
SITE SAFETY PLAN
Introduction:
A Site Safety Plan (SSP) has been designed to address safety provisions needed
during the confirmation boring. Its purpose is to provide established procedures to
protect all on-site personnel from direct skin contact, inhalation, or ingestion of
potentially hazardous materials that may be encountered at the site. The SSP
establishes personnel responsibilities, personal protective equipment standards
decontamination procedures, and emergency action plans.
AquaGeosciences, Inc. seeks to enter property described above for the purpose of
conducting a confirmation boring consisting of one (1) boring to evaluate the residual
contamination of the soil.
Soils samples will be collected at five-foot intervals during exploratory drilling using a
California modified split-spoon sampler through a hollow-stem auger. All possible
efforts will be made to collect undisturbed samples. Each sample to be chemically
analyzed will be collected in a brass sleeve, capped with lined plastic lids, sealed with
tape, and placed on ice in a cooler immediately. All Chain-of-Custody protocol will be
followed.
Drilling equipment will be brought to the site and operated by a subcontractor:
Soils Engineering, Inc.
4700 District Boulevard
Bakersfield.. California 93313
C-57 License Number 253192
The SSP describes means for protecting all on-site personnel from deleterious
contamination or personal injury while conducting on-site activities. As described
below we will meet all requirements promulgated by the California Department .of
Health Services.
Site Background:
This property is owned by Mr. Robb Pence, located at 901 E. Truxtun Ave.,
Bakersfield, California. The facility contained two (2) 6,000-gallon underground
gasoline storag,e tank and one (1) 10,000-gallon underground gasoline storage tanks.
1 4 of 1 9
e
e
Responsibilities of Key Personnel:
All personnel on site will have assigned responsibilities. Mr. Patrick
McCullough of AquaGeosciences, Inc. will serve as Project Manager and On-Site
Geologist. He will also serve as Site Safety Officer (SSO). As SSO, Mr. McCullough
will assure that on-site personnel have received a copy of SSP. Personnel will be
required to document their full understanding of the SSP before admission to the site.
Compliance with the SSP will be monitored at all times by the SSO. The SSO will
conduct a training session to assure that all are aware of safe work practices. In the
training session, personnel will be made aware of hazards at the site and will utilize
Material Safety Date Sheets for information on compounds to be encountered.
I .
Mr. Patrick McCullough will also be responsible for keeping field notes,
collecting and securing samples, and assuring sample integrity by adherence to
Chain-of-Custody protocol.
On-site employees will take reasonable precautions to avoid unforeseen
hazards. After documenting understanding of the SSP, each on-site employee will be
responsible for strict adherence to all points contained herein. Any deviation observed
will be reported to the SSO and corrected. On-site employees are held responsible to
perform only those tasks for which they believe they are qualified.
Provisions of this SSP are mandatory and personnel associated with on-site
activities will adhere strictly hereto.
Job Hazard Analysis:
Hazards likely to be encountered on site include those commonly encountered
when operating any mechanical equipment, such as the danger of falling objects or
moving machinery. -
Simple precautions will reduce or eliminate risks associated with operating
such equipmént.
A drilling contractor has been employed to deliver and operate all drilling
equipment. Qualified personnel only will have any contact with this equipment. .AII on-
site personnel, including the drilling contractor and his employees, are required to
wear hard hats when in close proximity to drilling equipment. Latex gloves will be
worn by persons collecting or handling samples to prevent exposure to contaminants.
Gloves will be changed between samples, and used ones discarded, to avoid cross-
contamination. Proper respiratory equipment will be worn if vapor contamination
levels on site exceed action levels as determined using a PID. Action
levels requiring respiratory apparatus will be 5 ppm, in the breathing space.
15 of 19
It
e
,
ð
.',
Furthermore, no on-site smoking, open flame, or sparks will be permitted in order to
prevent accidental ignition.
Risl< Assessment Summary:
Exposure to chemicals anticipated on site include gasoline, and benzene,
toluene, and xylene (BTX). These chemicals represent a hazard because they are
moderately to extremely toxic and most are highly flammable. Threshold Limit Values
(TLV's), Short Term Exposure Limits (STEL's), and Toxicity levels (LD50, oral-rat), all in
mg/kg (ppm), are listed below:
Compound TLV STEL
Gasoline 200 300
Benzene 10 25
Toluene 100 150
Xylene 100 150
Toxicity
4894
5000
4300
Benzene is considered an extreme cancer hazard.
Exposure Monitoring Plan:
A Photo-Ionization Detector (PID) will be used to monitor vapor concentrations
around the site. Should concentrations exceed TLV's, protective measures will be
taken. Passive dosimeter badges will be placed in downwind locations if PID reading
indicate high levels of volatile organics in the breathing space.
Personal Protective Equipment:
Personnel on site will have access to respirators with organic vapor cartridges.
Replacement cartridges will be available on site as needed. When handling samples,
the on-site geologist will wear latex gloves. Hard hats will be worn by all personnel on
site when in proximity of drilling equipment.
Work Zones and Security Measures:
Access to the site will be restricted to authorized personnel. A set of cones,
placards, or wide yellow tape, surrounding the site will define the perimeter. The
Project Manager will be responsible for site security
16 of 19
It
e
,
Decontamination Measures:
Avoidance of contamination whenever possible is the best method for
protection. Common sense dictates that on-site personnel avoid sitting, leaning, or
placing equipment on possibly contaminated soil.
All personnel will be advised to wash their hands, neck, and face with soap and
water before taking a break or leaving the site. Respirators will be washed with soap
and water following each day's use.
Drilling and sampling equipment used will be decontaminated by steam-
cleaning. Sampling equipment will be decontaminated before each sample is taken
and drilling equipment will be decontaminated before each boring is commenced.
General Safe Work Practices:
Drillers and other on-site personnel will be briefed each day in "tailgate"
meetings as to the day's goals and equipment to be used. Anticipated contaminants
and emergency procedures will be reviewed. Appropriate personal protective
equipment will be put on and verified correct by SSO, including respirator fit.
Drilling and sampling equipment will be steam-cleaned before being brought
on site. Split-spoon sampling equipment will be steam-cleaned before each use.
Augers will be steam-cleaned between borings.
The On-Site Geologist will oversee operations and log borings in consultation
with drillers. The Sample Coordinator will assure that proper protocol is used at all
times in collecting and handling samples.
Training Requirements:
The SSO will conduct a pre-site training session which will include all points of
MSDS forms: contaminant properties, warning signs, health hazard data, risk from
exposure, and emergency first aid. The SSO will assure that everyone fully
understands site hazards.
Medical Surveillance Program:
According to CFR 29,1910.120, Paragraph (f), employees who wear respirators .
30 days or more during one year or who have been exposed to hazardous substances
or health hazards above established permissible exposure limits are required to be
monitored medically. All site personnel will be required to have had a complete
chemical physiçal within the past year.
1 7 of 19
tit
e
Record Keeping:
Documentation will be kept on personnel exposed to contaminant hazards on
the job site according to OSHA regulations. These will include documentation that
employees have received training on the SSP, respiratory protection, MSDS forms,
and all emergency procedures. These will be reviewed during the pre-site training
meeting.
Exposure records on each job will be kept for 30 years to meet requirements.
Included will be names and social security number of employees, medical evaluation,
on-the-job logs from entry to exit, first aid administered, visits on site by outside
persons, and personal air monitoring records.
Contingency Plans:
In the event of accident, injury, or other emergency, the Project Director, Senior
Project Manager, or other person will notify appropriate government agencies or

RE: Addendum to Closure Workplan for Remediation of Gasoline Impacted Soil at
Pence Petroleum located at 901 E. Truxtun Avenue, Bakersfield, California.
Dear Ms. Darling:
Pursuant to our phone conversation on April 8, 1994, the information you requested
regarding the quantities of propane used and the volume of removed contaminants as
foUows.
PROPANE USAGE
DATE QUANTITY
09/24/92 114 gallons
09/14/93 142 gallons
12/16193 194 gallons
12/17/93 169 gallons
01/10/94 174 gallons
02/07/94 193 gallons
Total 986 gallons
Note: Propane use records were obtained from Pence Petroleum files.
INSITU CONTAMINANT REMOVAL
An estimation of the final removal of hydrocarbons from the subsurface by the IC
Engine was calculated using the ideal gas law, stated as follows;
Ibs/day. = (ppm of constituent 1 E6)(lbs/lb-mole of constituent)
(volume of air; cfm) (atm. pressure; psi) (144 sq. in.! sq. ft.)
(60 min/hr) (hours run) divided by (1545) (temp.; deg. R).
1701 Westwind Drive, Suite 101 · Bakersfield, California 93301
(BOS) 328-0962 · FAX (80S) 328-1129
e
.
The estimation of hydrocarbon volumes were also based on the following
assumptions:
Hydrocarbon concentrations necessary to maintain operation of IC Engine = 5000
ppmv
Molecular weight of hydrocarbon = 86 Ib/lb-mole
Vapor flow rate = 58 cubic feet/minute
Standard conditions for temperature and pressure
Density of hydrocarbons = 53 Ibs/cubic foot
From the ideal gas law, an estimated 1.55 pounds of hydrocarbons vapors are
removed and consumed per hour. This volume translates into the following hourly rate
of usage:
1.55 Ibs/hour
53 Ib/cubic foot
X 7.48 gallons / cubic foot = 0.22 gallons/ hour
The VES machine has run for 9,561 hours since start-up of the equipment and has
used 986 gallons of supplemental propane. Therefore, the machine has removed
approximately 1,117.42 gallons from the subsurface (9,561 hours X 0.22 gallons/hour -
986 gallons of propane).
Should you require additional information or wish to discuss this matter, please contact
the undersigned.
Respectfully Submitted,

Dear Mr. Pence:
This letter is an official notice to inform you that, as the responsible party for
the property described above, your agreement with the Kern County Environmental
Health Services Department is about to expire, in accordance with Section d.2. of
that agreement, which states:
"Fourteen (14) hours of billable time has been reached. This will give
notice that the available funds will be exhausted after six (6) addi-
tional hours of billable time at which time the agreement will expire.
A statement estimating the amount time necessary to complete any
remaining oversight work will be sent. The responsible party will
then have another opportunity to renew their agreement with the County.
"Failure to enter into another agreement shall require Kern County
Environmental Health to utilize the State Water Resources Control Board
pilot Project for which the responsible party may be billed by the
State directly for the cost of County services as well as State costs."
You are hereby notified that the current balance in your trust account is $266.44.
Remaining oversight will require an estimated 40 hours to complete. We are,
therefore, extending this opportunity to renew your agreement with Kern County
Environmental Health Services Department or to utilize the State Water Resources
Control Board Pilot Project for completion of the required oversight activities.
As a responsible party, you must provide for all studies and work relatin9 to the
above-described property and the cost for oversight of these actlvities.
California Health and Safety Code, Chapter 6.7, and Kern County Ordinance Code,
Chapter 8.48, require a determination of the threat to the environment as a result
of this release.

The cost incurred by Kern County Environmental Health Services Department for the
oversight of the work for the site characterization, feasibility study, remediation
action plan, site remediation, and ongoing monitoring is not covered by any fees
or permits.
These costs are recovered by Kern County Environmental Health Services Department
in one of the two methods described below. It is your responsibility to select the
method of oversight cost recovery under the terms of (A) State contract or (8)
County of Kern Local Agreement Option. These options pertain only to costs
associated with oversight.
(A) STATE CONTRACT
The State Leaking Underground Storage Tank Pilot Program provides a mechanism for
the State to reimburse the County for County oversight. The County will conduct
the necessary oversight and bill the State Water Resources Control Board under this
State contract. The State will then charge you, a responsible party, for the costs
incurred by both the County and the State, pertaining to your site, under the State
terms explained below:
Whereas the Legislature has appropriated funds from the California Hazardous
Substance Clean-up Fund to pay the local and state agency administrative and
oversight costs associated with the cleanup of releases from underground
storage tanks;. and Whereas the direct and indirect costs of ov.erseeing
removal or remedial action at the above site are funded, in whole or·in part,
from the Hazardous Substance Cleanup Fund; and Whereas the above indivi-
dual(s) or entity(ies) have been identified as the party or parties
responsible for investigation and cleanup of the above site; YOU ARE HEREBY
NOTIFIED that pursuant to Section 25360 of the Health and Safety Code, the
Above Responsible Party or Parties shall reimburse the State Water Resources
Control Board for all direct and indirect costs incurred by any and all state
and local agencies while overseeing the cleanup of the above underground
storage tank site, and the above Responsible Party or Parties shall make full
payment of such costs within 30 days of receipt of a detailed invoice from
the State Water Resources Control Board.
(B) COUNTY OF KERN LOCAL AGREEMENT OPTION
Kern County Environmental Health Services Department is providing this option for
those who prefer to pay the County directly and avoid the addition of State costs.
Prior to the County's performance of services, this option requires your deposit
of $1,000.00 (one thousand dollars) with the County to be held in the Local Option
Trust Account. Charges for County oversight are made against this account. In
this option, a responsible party must enter into a County agreement, Attachment
IIBII.
The environmental sensitivity (Attachment IICII) of this site has been reviewed by
Environmental Health Services Department to determine the potential threat for
groundwater contamination. Only sites determined to be non-environmentally
sensitive may enroll in the Local Option Agreement. The site described above is
e
e.
Robb Pence
October 8, 1990
Page 3
not in an environmentally sensitive area and may be enrolled in the Local Agreement
Opt 'j on: however, the County of Kern reserves the ri ght to cancel any Local
Agreement Option, should it be discovered that groundwater contamination or a
unique, complex hydrogeological condition exists. In such cases, Environmental
Health Services Department will util ize the State contract to pay for County
oversight activities. The County of Kern res~rves this right for any site even
when the site is located in a non-environmentally sensitive area.
It is necessary for you to respond, in writing, within ten (10) ,calendar days of
receipt of this letter to advise Kern County Environmenta1 Health Services
Department of your choice: either the State contract or the County's Local
Agreement Option. If you select the County's Local Agreement, please complete and
sign the Local Agreement (Attachment B) and return it with your check for $1,000.00
(one thousand dollars) made payable to the County of Kern, addressed to Kern County
Environmental Health Services Department, 2700 M Street, Suite 300, Bakersfield,
CA 93301, Attention: Accounting - Local Agreement Option. If you select the
State contract, please indicate, in writing, that you have made this selection and
that you have read the above official notification.
Failure to respond within ten (10) calendar days to this notice will automatically
result in oversight cost recovery for your site(s) to be placed under the terms of
the State contract for Leaking Underground Storage Tanks.
If you should have any questions regarding this matter, please contact Susan
Gonzales at (805) 861-3636, Extension 510.

Dear Mr. Pence:
The partial Site Characterization Report submitted by Associated Soils Analysis (ASA) has
been reviewed.
The Report is incomplete since the vertical depth of the contamination plume in boring
B3A has not been defined, nor has the eastern lateral limits of boring B3. (See Figure 4.) A
discussion of possible remediation techniques is also lacking.
It appears that an informal conference should be held to discuss further work and
possible combination of remediation techniques for the site. Please telephone me at (805)
861-3636 extension 549 to schedule a mutually convenient time as soon as possible.

Dear Mr. Pence:
The preliminary site assessment borings for the above-
referenced site were completed by Associated Soils Analysis in
November, 1990. To date, our Department has not received the site
characterization report.
In order to move forward to site characterization and
subsequent remediation procedures, all reports must be submitted
for review in an orderly manner.
Time constraints for submittal of pertinent reports are
clearly defined in Handbook UT-35. At this time, you should
contact your environmental contractor with instructions to submit
the site characterization report to this office immediately. The
report should reach my desk wi thin 15 days of receipt of this
letter.
If you have any questions, contact me at (805) 861-3636 ext.

Dear Mr. Pence:
A review of the above referenced sites file reveals initial site
characterization boring operations of July 7, 1990, have not been completed.
As you are aware there are time constraints for submitting workplans and
reports. The initial field investigation is due 30 days after workplan approval.
The site characterization Final Reports are due within 60 days of completion of the
Field Investigation.
At this time the Field Investigation Reports are overdue. Since over 60 days
has elapsed since the beginning of the Field Investigation, our Department feels
adequate time has been allowed for site characterization to have been completed.
Therefore, please contact your Environmental Contractor with instructions to
proceed with the work needed to fully characterize this site, and to copy all
reports to this office for review.
If you have any questions contact me at (805) 861-3636 extension 549.

Dear Mr. Pence:
Our Department has reviewed the site characterization workplan submitted by
Associated Soils Analysis (ASA) for the above referenced site. Our comments are
as foll ows:
1. j Gradient is not mentioned. Gradient is necessary to detennine the most
feasible boring locations. A U.S.G.S. map showing contours should be
submitted for this location. The map may be limited to the area
undergoing site characterization.
2. v Boring locations are spaced too far apart and are not located to best
define the suspected contaminant plume. Bore holes shall be limited
to three; four are excessive.
Soil sampling shall begin at grade and proceed at five foot intervals
and at any change in lithology.
All underground utilites and above ground obstructions (power lines)
shall be depicted on the plot plan.
Constituents to be analyzed shall include total petroleum hydrocarbons
(gasoline) and BXTE. Analyses for the removed 6,000 gallon leaded
gasoline tank shall include organic lead and E.D.B.
Upon receipt of the above addendum information and a revised plot plan our
office will continue the review. A consultation may be scheduled by appointment
if necessary.

Dear Mr. Pence:
The intent of this letter is to inform you of the necessary deadlines for
work required at the property described above. As a responsible party for a
leaking underground storage tank, you have previously received a letter from
this Department notifying you of the required work necessary to identify the
extent of the contamination. We are now requesting that this work, outlined
in UT-35, be done in a timely manner.
In accordance with California Health and Safety Code Chapter 6.7 and
Kern County Ordinance Code Chapter 8.48, the Kern County Environmental
Health Services Department requires a determination of the threat to the
environment. Accordingly, you must select an environmental contractor and
submit a site characterization workplan proposal to this office within 30 days
from the date of this letter. The workplan must be approved by this
Department before any work is started.
If you should have any questions regarding this matter, please contact me
immediately at (805) 861-3636.

This letter is an official notice to inform you that the property described above has
been determined by Kern County Environmental Health to be the site of an unauthorized
release of hazardous materials from an underground storage tank. This notice ;s sent
to you because our records indicate that you are a responsible party for this property.
As a responsible party, you must provide for all studies and work relating to the
above described property and the cost for oversight of these activities. California
Health and Safety Code Chapter 6.7 and Kern County Ordinance Code Chapter 8.48 require
a determination of the threat to the environment as a result of this release. THE
RESPONSIBLE PARTY SHALL, ON A TIMELY BASIS, DEVELOP A SITE CHARACTERIZATION,
FEASIBILITY STUDY AND REMEDIAL ACTION PLAN FOR KERN COUNTY ENVIRONMENTAL HEALTH'S
REVIEW AND APPROVAL BEFORE THE WORK IS INITIATED. Enclosed you will find attachment

The samples were delivered to B. C. Laboratories in Bakersfield,
California (see Attachment C). The samples were analyzed for
T.P.H. gasoline and B.T.X.& E. B. C. Laboratories is a state
certified laboratory. As shown on Attachment D, T.P.H. (gasoline)
and B.T.X.& E. were detected in a number of the samples. The
samples from below the eastern pump showed some minor levels of
contamination. Total petroleum hydrocarbon levels of 66.50 ppm at
6 feet were detected. Soil samples from below the east ends of
Tanks 2 and 3 showed high levels of contamination. Samples from
below the east end of Tank 1 showed low levels of contamination.
Soil samples from below the west ends of the tanks showed only
slight contamination to none-detected.
Based on the results of this investigation, further site
characterization is deemed necessary to delineate the vertical and
horizontal extent of the contamination and the degree of contamination.
Also included with this report (see Attachment E) is a copy of the
tracking record, hazardous waste manifest, and a copy of the
permit.
If you have any questions regarding this report, please feel free
to call.

Ms. Turonda Crumpler
c/o Kern County Health Department
Environmental Health Services
2700 "M" Street, Suite 300
Bakersfield, California 93301
Dear Ms. Crumpler:
Three underground fuel storage tanks were removed on November 1,
1989 from the Pence Automated Fuels property located at 901 E.
Truxtun Avenue in Bakersfield, California. The property is
situated in Section 29, T.29S., R.28E., M.D.B.& M. (see Attachment
A) .
The three tanks had a volume of 10,000, 6,000, and 6,000 gallons
and were used for the storage of gasoline. The tanks had been in
place for a number of years. The tanks were in fairly good
conãition and showed no signs of leakage. A petroleum odor was
emanating from the excavation pit when the tanks were removed. The
tank removal was witnessed by Ms. Turonda Crumpler, Hazardous
Materials Specialist for the Kern County Health Department.
'"-
Sixteen soil samples were collected by Mr. Tom Pruitt of M. P.
Vacuum as directed by U.T.-30. The samples were collected at
depths of 2 feet and 6 feet beneath the bottom of the tanks at the
sample locations shown on Attachment B. Four of the sixteen soil
samples were collected from beneath the two dispenser pumps.
The samples were collected from a backhoe bucket. The samples
were placed in jars, labeled, and sealed. The samples were then
placed on dry ice and retained for laboratory analysis.

RECOMMENDATIONS/GUIDELINES FOR REMOVAL OF UNDERGROUND STORAGE TANKS
This department is responsible for enforcing the Kern County Ordinance Code, Division 8 and state regulations pertaining to underground storage tanks.
Representalives from this department respond to job sites during tank removals to ensure that the tanks are safe to remove/close and that the overall
job performancc is consistent with permit requirements, applicable laws and saFety standards. The following guidelines are offered to clarify the interests
and expectations for this department.
1. Job site sa[t:ty is one of our primary concerns. Excavations are inherently dangerous. It is the contractor's responsibility to know and abide by
CAL-OSHA regulations. The job foreman is responsible [or the crew and any subcontractors on the job. As a general rule workers are not
permitted in improperly sloped excavations or when unsafe conditions exist in the hole. Tools and equipment are to be used only [or their designed
[unction. For example, backhoe buckets are never substituted [or ladders.
2. Properly licensed contractors are assumed to understand the requirements o[ the permit issued. The job foreman is responsible [or knowing and
abiding by the conditions o[ the permit. Deviation from the permit conditions may result in a slop-work order.
3. Individual contractors will bc held responsible [or their post-removal paperwork. Tracking forms, hazardous-waste manifests and analyses
documentation is necessary [or each site in order to close a case file or move it into mitigation. When contractors do not follow through on
necessary paperwork, an un,manageable backlog of incomplete cases results. If this continues, processing time for completing new closures will
increase. p'
