1.0 INTRODUCTION/BACKGROUND
EnecoTech Southwest, Inc. (EnecoTech) is pleased to provide this work plan to conduct
soil assessment activities at the Sun Valley Oil Texaco fuel station located at 726
South Union Avenue, Bakersfield, California (Figure 1).
In March 1997, a waste oil underground storage tank (UST) was removed by Lutrel
Services of Bakersfield, California. Based on EnecoTech's review of the laboratory
results, it is apparent that soil samples were collected from 2 and 6 feet below the
bottom of the previous waste oil UST. The sample" @2' .. was reported by BC
Laboratories to contain 5800 milligrams per kilogram (mg/kg) of total petroleum
hydrocarbons using EPA method 418.1. The sample" @6' .. was reported by BC
Laboratories to contain 1200 mg/kg of total petroleum hydrocarbons using EPA method
418.1.
2.0 OBJECTIVE
The objectives of the Soil Assessment are to assess the vertical extent of soil impact
in the area beneath the previous waste oil UST.
3.0 SCOPE OF WORK
To accomplish the stated objective, EnecoTech proposes to drill and collect soil
samples from one soil borings to a depth "6f 30 feet below ground surface (bgs).
Based on the estimate that the bottom of the previous UST was 7 feet below ground
surface (bgs) , the impacted soil samples are estimated to have been collected from
respective depths of 9 and 13 feet bgs. Therefore the soil samples from 15, 20, 25,
and 30 feet bgs will be analyzed using USEPA Method 418.1 for total petroleum
hydrocarbons.

4.0 SOIL SAMPLING PROTOCOL
The soil borings will be drilled using a direct push technology rig utilizing Geoprobe
equipment, operated by a C-57 licensed drilling company. The rig will be equipped
with 2-inch diameter push rods. Push rods will be steam-cleaned between borings
to prevent cross-contamination.
The soil samples will be collected at 5-foot intervals from a depth of 5 feet to the
total depth of the boring. The samples will be collected using a modified spoon
sampler lined with brass tubes, driven into the ground with pressure.
One brass tube from each sample location will be sealed with Teflon tape, capped,
labeled, and stored in a chilled ice chest until delivered to the analytical· laboratory.
Another portion of each recovered sample will be placed into zip-lock plastic bags,
sealed, and agitated for 15 to 60 seconds. A PID will then be used to measure and
record organic vapor concentrations. The PID will be calibrated with 100 ppm
isobutylene prior to beginning field work. All samplÜ1g equipment will be washed
before sampling in a Alconox (soap) solution and thoroughly rinsed. Based on the
results of the PID on each sample interval, a minimum of four soil samples from
each boring will be analyzed. The geologist in the field will use the remaining
recovered sample to describe the soil in accordance with the Unified Soil
Classification System (USCS). Additionally, a qualitative characterization of
contamination will be made based upon any petroleum hydrocarbon odors or soil
discoloration. These observations and USCS descriptions will be included in the
Boring Logs, which will be reviewed by a California Registered Geologist.
5.0 ANALYTICAL PROCEDURES

Ë
F
ti
f
,
Each soil sample will be hand delivered to a State-certified hazardous waste testing
laboratory. The four samples will be analyzed for Total Petroleum Hydrocarbons as
gasoline USEPA Method 418.1. The laboratory reports for soil sample results will
be included in the Site Assessment Report.
6.0 REGIONAL GEOLOGIC/HYDROGEOLOGIC SETTING
6.1 Regional Physiographic Conditions
The subject site is located in the southern San Joaquin Valley. This area is bound
by the southern portion of the Sierra Nevada Mountain Range to the east, the
Transverse Ranges and the Tehachapi Mountains to the south, and the southern
portion of the coast ranges to the west. The general topography of the Bakersfield
region consists of alluvial terraces, fans, benches, and floodplains sloping westward
form the foothills of the Southern Sierra Nevada Mountains to the main drainage
axis of the San Joaquin Valley. The Kern River, a perennial stream draining an
extensive watershed in the souther Sierras, flows in a general southwesterly
direction through the center of the metropolitan Bakersfield area. Temperatures in
this region average 57° F in the winter and 90° F in the summer months. Annual
average precipitation ranges between 4 to 6 inches, with most rainfall occurring
between the months of November and April.
6.2 Geologic Conditions
"
¡:
(.
The San Joaquin Valley is a large basin lying between the Sierra Nevada range to
the east, and the coastal ranges to the west. This basin was formed in intermittent
westerly tilting of the underlying Mesozoic crystalline rocks, which elevated the

Sierra Nevada and depressed the western portion of the block. Duling Tertiary and
Quaternary peliods, both marine and non-marine sediments were deposited on the
basement rocks as the western portion was depressed. The tertiary rocks consist of
a selies of stratified sediments including sandstone, conglomerates, and shales that
are relatively thin along the eastern margin and become increasingly thicker towards
the southwest. Tertiary sediments are generally overlain by Quaternary sediments
of varying thicknesses, including Pleistocene non-marine terraces and fans and
Holocene fans and alluvium. During the late Pliocene and early Pleistocene, the
ancestral Kern River deposited a huge alluvial fan which spread for many miles in
what is now Bakersfield. Subsequent uplift of the Sierra Nevada raised the fan to
its current elevation. Erosion by the Kern River and its seasonal tributaries has
produced the topography of the region.
6.3 Soil Conditions
The soils in the general area of the site consist of alluvial fan deposits delived from
the Sierra Nevada uplands and transported by the Kern River. This alluvium
generally consists of unconsolidated, indistinctly bedded, conglomerate containing
sand, silt, gravel and boulders.
;.,
6.4 Groundwater Conditions
Local groundwater is generally found in shallow alluvial sediments of Holocene age,
normally in unconfmed aquifers, frequently becoming semi-confined with depth.
Beneficial uses of groundwater in the area include agliculture, municipal, and
industrial applications.
"
Groundwater in the area is usually more than 100 feet below ground sunace.

7 .0 REPORT/SCHEDULE
Field investigative work should require no more than two weeks to be completed.
Upon completion of the field work, EnecoTech will prepare a Site Assessment
Report, which will be submitted to the City of Bakersfield Fire Department within
45 days of completion of field work. The report will detail the scope of work, the
investigative procedures, and the results of the investigation.

EnecoTech Southwest. Inc. (EnecoTech) is pleased to provide this work plan to
conduct soil assessment acti\ities at the Luch")'-7 #3 J\-1ini-Mart. located at 726 South
Union Avenue. Bakersfield. California (Figure 1).
In December. 1994. soil samples were collected adjacent to the dispensers and
associated piping. Gasoline compounds were detected at concentrations up to 22.000
milligrams per kilogram (mg/kg). Diesel was also deleted at concentrations up to
1.500 mg/kg. In a letter dated January 12. 1995. the City of Bakersfield requested
that a work plan be submitted to assess the e:x1:ent of contamination. This work plan
was prepared by EnecoTech to submit to the City of Bakersfield Fire Department,
Hazardous Ì\1aterials Division.

On March 29. and April 21. 1995. nine additional soil borings were drilled using a
truck-mounted hollow stem auger. A total of 54 soil samples were submitted for
laboratory analysis. Gasoline compounds \vere detected at concentrations up to
24.000 mg/kg. Benzene. toluene. ethylbenzene. and xylene (BTEX) were detected at
concentrations of up to 220. 2.500. 510. and 3.300 mg/kg. respectively. Analy1:ical
data from these soil borings indicates that impacted soil may extend beneath
properties north of the subject site and South Union Avenue. to the west of the
subject site. In a letter dated September 13. 1995. the City of Bakersfield Fire
Department requested that a work plan be submitted to assess the lateral extent of
contamination. This work plan was prepared by EnecoTech to submit to the City of
Bakersfield Fire Department, Hazardous Materials Division. ..... , .
2.0 OBJECTIVE
The objectives of the Soil Assessment are to assess the lateral 3l1d vertical extent of
soil impact in the area beneath properties north 3l1d west of the subject site.
3.0 SCOPE OF WORK
.....
To accomplish the stated objective. EnecoTech proposes to drill and collect soil
s31nples from four (4) soil borings to minimum depths of 80 feet below ground surface
(bgs). The soil s31nples \vill be selected for 3l1alysis based on the field observations
and photoionization detector (PID) readings for each sample. The proposed boring
locations are subject to the location of underground utilities.

4.0 SOIL SA.'I\1PLING PROTOCOL
The soil borings will be drilled llsing a truc1,-mounted hollow stem auger drill rig
operated by a C-57 licensed drilling company. The rig will be equipped with G-inch
diameter hollow stem augers. Augers \vill be steam-cleaned between borings to
prevent cross-contamination. Auger cleaning rinsate \\ill be contained in 55-gallon
DOT-approved drums. ,"
The soil samples will be collected at 5-foot intervals from a depth of 5 feet to the total
depth of the boring. The samples will be collected using a modified California Split
.Spoon S3111pler lined with brass tubes. driven into the ground with a l40-lb.. rig-
operated safety h3111mer. Relative penetration resistance will be measured by counting
the number of hammer blows (blow counts) required to drive the sampler a distance
of 18 inches. in 6-inch increments. Blow counts will be recorded on the boring logs.
One brass tube from each sample location will be sealed with teflon tape. capped.
labeled. and stored in a chilled ice chest until delivered to the analytical laboratory.
Another portion of each recovered sample \\-ill be placed into zip-lock plastic bags.
sealed, and agitated for 15 to 60 seconds. A PID \\ill then be used to measure and
record organic vapor concentrations. The PID will be calibrated with 100 ppm
isobuty'lene prior to beginning field work. All sampling equipment will be washed
before sampling in a Alconox (soap) solution and thoroughly rinsed. Based on the
results of the PID on each sanlple interval. a minimum of four soil s31nples from each
boring will be analyzed. The geologist in the field will use the remaining recovered
sample to describe the soil in accordance with the Unified Sou Classification System
(USCS). Additionally. a qualitative characterization of contamination will be made
based upon any petroleum hydrocarbon odors or soil discoloration. These
observations 311d USCS descriptions will be included in the Boring Logs. which will
be reviewed by a California Registered Geologist.
5.0 ANALYTICAL PROCEDURES
Each soil sample will be hand delh'ered to a State-certified hazardous waste testing
laboratory. Three to four samples fro111 each soil boring will be analyzed for Total
Petroleum Hydrocarbons as gasoline (TPHg) or Total Petroleum Hydrocarbons as diesel
(TPHd) by the DHS-approved EPA Method SOI5m: and BTEX using EPA Method 8020.
The laboratory reports for soil sample results will be included in the Site Assessment
Report.

The San Joaquin Valley is a large basin lying between the Sierra Neyada range to the
east. and the coastal ranges to the west. This basin was formed in intermittent
westerly tilting of the underlying Mesozoic crystalline rocl{s. which elevated the Sierra
Nevada and depressed the western portion of the block. During Tertiary and
Quaternary periods. both marine and non-marine sediments were deposited on the
basement rocks as the western portion was depressed. The tertiary rocks consist of
a series of stratified sediments including sandstone. conglomerates. and shales that
are relatively thill along the eastern margin and become increasingly thicker towards
the southwest. Tertiary sediments are generally overlain by Quaternary sediments of
varying thicknesses, includillg Pleistocene non-marine terraces and fans and Holocene
fans and alluvium. During the late Pliocene and early Pleistocene. the ancestral Kern
River deposited a hugh alluvial fan which spread for many miles in what is now
Bakersfield. Subsequent uplift of the Sierra Nevada raised the fan to its current
elevation. Erosion by the Kern River and its seasonal tributaries has produced the

1.0 INTRODUCTION/BACKGROUND
EnecoTech Southwest, Inc. (EnecoTech) is pleased to provide this revised work plan to
conduct soil assessment activities at the Sun Valley Oil Texaco fuel station located at
726 South Union Avenue, Bakersfield, California (Figure 1).
In March 1997, a waste oil underground storage tank (UST) was removed by Lutrel
Services of Bakersfield, California. Based on EnecoTech's review of the laboratory
results, it is apparent that soil samples were collected from 2 and 6 feet below the
bottom of the previous waste oil UST. The sample .. @2' .. was reported by BC
Laboratories to contain 5800 milligrams per kilogram (mg/kg) of total petroleum
hydrocarbons using EPA method 418.1. The sample" @6' .. was reported by BC
Laboratories to contain 1200 mg/kg of total petroleum hydrocarbons using EPA method
418.1:
2.0 OBJECTIVE
The objectives of the Soil Assessment are to assess the vertical extent of soil impact
in the area beneath the previous waste oil UST.
3.0 SCOPE OF WORK
To accomplish the stated objective, EnecoTech proposes to drill and collect soil
samples from four soil bortngs to a depth of 30 feet below ground surface (bgs).
Based on the estimate that the bottom of the previous UST was 7 feet below ground
surface (bgs) , the impacted soil samples are estimated to have been collected from
respective depths of 9 and 13 feet bgs. Therefore the soil samples from 15, 20, 25,
and 30 feet bgs will be analyzed using USEPA Method 5520 for total petroleum
hydrocarbons from the soil boring installed in the previous waste oil UST
excavation. Two soil samples will be selected from each of three bortngs outside the
UST excavation for analyses using US EPA method 5520. The soil sample from .
each bortng with the highest 5520 detection will be additionally analyzed for
Chlortnated Solvents by EPA Method 8010 and for the metals Cd, Cr, Pb, Zn, and
Ni by EPA method 6010.
The tentative location of the soil bortngs are indicated in Figure 1. Drilling and
sampling activities will be conducted under the supeIVision of a California
Registered Geologist.
Each soil boring will be backfilled with bentonite chips and sealed at the top with
concrete. EnecoTech will notify Underground Service Alert and the City of
Bakersfield Fire Department 48 hours prior to any field activities.

4.0 SOIL SAMPLING PROTOCOL
The soil borings will be dIilled using a direct push technology rig utilizing Geoprobe
equipment, operated by a C-57 licensed drilling company. The rig will be equipped
with 2-inch diameter push rods. Push rods will be steam-cleaned between borings
to prevent cross-contamination.
The soil samples will be collected at 5-foot intervals from a depth of 5 feet to the
total depth of the boring. The samples will be collected using a spoon sampler
lined with brass tubes, driven into the ground with pressure.
One brass tube from each sample location will be sealed with Teflon tape, capped,
labeled, and stored in a chilled ice chest until delivered to the analytical laboratory.
Another portion of each recovered sample will be placed into zip-lock plastic bags,
sealed, and agitated for 15 to 60 seconds. A PID will then be used to measure and
record organic vapor concentrations. The PID will be calibrated with 100 ppm
isobutylene prior to beginning field work. All sampling equipment will be washed
before sampling in a Alconox (soap) solution and thoroughly rinsed. Based on the
results of the PID on each sample interval, a minimum of four soil samples from
each boring will be analyzed. The geologist in the field will use the remaining
recovered sample to describe the soil in accordance with the Unified Soil
Classification System (USCS). Additionally, a qualitative chaÌacterization of
contamination will be made based upon any petroleum hydrocarbon odors or soil
discoloration. These observations and USCS descriptions will be included in the
Boring Logs, which will be reviewed by a California Registered Geologist.
5.0 ANALYTICAL PROCEDURES
Each soil sample will be hand delivered to a State-certified hazardous waste testing
laboratory. Selected soil samples will be analyzed for the parameters stated in the
scope of work. The laboratory reports for soil sample results will be included in the
Site Assessment Report.

All soil samples were collected using brass tubes. Each end of the tube was sealed with a Teflon
sheath and capped with a soft rubber end-cap. A total of 16 samples were collected (Four (4) from
each boring). The samples were shipped in a sample cooler with ice, accompanied by a
completed chain-of-custody, and submitted to A TL Analytical Laboratories for analyses of Total
Petroleum Hydrocarbons (TPH), Chlorinated Solvents, and Metals. According to the laboratory
record, the samples were analyzed in accordance with EPA-approved methods as described in
EPA Manual SW-846. Copies of the laboratory reports can be found as Appendix C. The soil
samples were submitted to A TL Laboratories for the following analyses:
· Total Petroleum Hydrocarbons (TPH) - EPA Method 418.1
· Chlorinated Solvents - EP A Method 8010
· Metals (Cd, Cr, Pb, Zn) EPA Method 6010
Soil samples that indicated elevated Photo-ionization Detector (PID) readings were placed on ice
and shipped to a California-certified environmental laboratory. Upon completion of the soil
borings, each boring was backfilled with bentonite, and the boring subsequently hydrated.
Asphalt patch was used to re-surface the boring entrance. All boring logs can b~ found as

· All soil cuttings were be placed and stored in 5-gallon pails and transported off-site by
EnecoTech's sub-contractor;
· EnecoTech's sub-contractor affixed a label marked "Non-Hazardous" with their project
number on each pail;
· All fluids produced during the drilling activities were placed and temporarily stored in
5-gallon pails with covers; and
· EnecoTech's sub-contractor transported all fluids off-site.
All fieldwork was conducted i!J accordance with EP A guidelines for soils testing and sampling.
Quality assurance / quality control procedures were followed during all field activities.
Site Investigation
A subsurface hydrocarbon investigation was conducted in the area of a former waste oil tank on
September 7, 1999. Four (4) hydraulic push probe borings (WOSB-I - WOSB-4) were
completed utilizing Geoprobe technology. The total depth of each of the four soil borings was
30' below ground surface (bgs). Soil samples were collected at 5-foot intervals throughout the
vertical extent of the boring. A detailed site map, boring location map, and boring logs can be
found in Appendix B.
Soil Analytical Results
No parameters were detected and no concentrations were found to be above regulatory
guidelines for chlorinated solvents (EPA Method 8010), TPH (EPA Method 418.1) or five metals
(EP A Method 60 I 0) per laboratory results. Certified laboratory reports and chains-of-custody
documentation can be found as Appendix A & C.
;.~...
Conclusions & Recommendations
Laboratory results clearly indicate that no contamination was found. Therefore, no additional
investigation is warranted in the area of the former waste oil underground storage tank.
