EXECUTIVE SUMMARY
A Phase II site investigation was conducted in August 1993 at Unocal service station No.
7048, located at 2518 White Lane, Bakersfield, California. The investigation identified
concentrations of total petroleum hydrocarbons as diesel (TPH-D) as high as 12,000
milligrams per kilogram (mg/kg) beneath dispenser island 3 at 8 feet below ground
surface (bgs). Total petroleum hydrocarbons as gasoline (TPH-G) appear to have been
limited primarily to depths of no more than approximately 40 feet bgs, at which depth
concentrations of 5,400 mg/kg were identified. Traces of benzene, toluene, ethyl benzene,
and total xylenes were found to 48 feet bgs.
Several technologies were considered for the remediation of diesel fuel and gasoline in
soil at this site. Excavation was considered the most costly altemative and the most
disruptive. Therefore, in situ remediation alternatives were evaluated for application at
this site. Soil vapor extraction technology is proposed to remove volatile petroleum
hydrocarbons from soil impacted by TPH-G beneath dispenser island 1 by mechanically
drawing or venting air through the soil matrix. Carbon adsorption will be used to treat
vapors extracted from the soil. Vapor extraction technology is also proposed to stimulate
bioremediation of TPH-D-affected soil beneath dispenser island 3 by inducing the flow of
moist, oxygen-rich air through the affected soil matrix (bioventing).
Upon the completion of remediation, confirmation samples will be collected from site soils
and clean closure of the site will be requested.

1.0 INTRODUCTION
This Workplan for Soil Remediation (Workplan) presents the selected alternative to
mitigate subsurface soil containing petroleum hydrocarbons at the former Unocal service
station No. 7048 located at 2518 White Lane, Bakersfield, California (site) (Figure 1). The
Workplan, prepared for Unocal Corporate Environmental Remediation and Technology
(Unocal CERT) describes soil quality beneath the site and the design specifications and
operating conditions for the selected soil remediation system. Approval of this workplan
is required by the Bakersfield Fire Department prior to implementation.
2.0 SITE BACKGROUND AND HISTORY
The station was decommissioned in early 1992 and the UST's, product lines, and
dispensers were removed in September 1992. The site is presently fenced and
unoccupied. A Phase II site investigation was conducted at the site in August 1993. The
purpose of the investigation was to determine the vertical and lateral extent of petroleum
hydrocarbons that were identified at the site when the underground fuel storage tanks
(USTs) and product lines were removed (GeoResearch, 1993a).
2.1 DISPENSER ISLAND NUMBER 1
Field observations and laboratory analyses of soil samples collected beneath dispenser
island 1 (Figure 2) indicate source areas of gasoline release at each end of the island.
The penetration of gasoline appears to have been limited primarily to depths of no more
than approximately 40 feet below ground surface (bgs). The maximum concentration of
5,400 mg/kg of total petroleum hydrocarbons as gasoline (TPH-G) was in a soil sample
collected at 33 feet bgs from SB2 (Figure 4). Traces of benzene, toluene, ethyl benzene,
and total xylenes (BTEX) were identified to 48 feet bgs in SB2 and SB3 (GeoResearch,
1993b). BTEX constituents were not detected at 58 and 63 feet bgs in 883.
It appears that hydrocarbons leaking from the west end of the island may have been
impeded by a change in lithology from silty sand to sandy silt. It is estimated that 500
cubic yards of soil beneath dispenser island 1 contains significant concentrations of TPH-
G (GeoResearch, 1993b). The analytical data for the soil samples are presented in
Appendix A.

2.2 DISPENSER ISLAND NUMBER 3
Concentrations of total petroleum hydrocarbons as diesel (TPH-D) as high as 12,000
milligrams per kilogram (mg/kg) were identified beneath dispenser island 3 (Figure 2), at
8 feet bgs in soil boring SB1 (GeoResearch, 1993b). Soil samples collected at 13, 18,
and 23 feet bgs in SB1 contained TPH-D concentrations of 8,500,4,200, and 1.0 mg/kg,
respectively (Figure 3). Soil boring SB5, drilled 15 feet west of the diesel dispenser, did
not contain detectable TPH-D. It is estimated that 100 to 200 cubic yards of soil beneath
dispenser island 3 contains diesel fuel (GeoResearch, 1993b). The analytical data for the
soil samples are presented in Appendix A.
2.3 FORMER UST PIT
Soil boring SB4, drilled in the former UST pit, encountered fill soils from the UST removal
activities to a depth of 28 feet. Analysis of the 30-foot sample for TPH-D revealed a
concentration of 350 mg/kg and low concentrations of toluene, ethyl benzene and total
xylenes. Only trace concentrations of BTEX were detected below a depth of 30 feet
beneath the former tanks (Appendix A). Based on the analysis of soil samples collected
upon the completion of excavation of soil following UST removal, soil containing
petroleum hydrocarbons was removed to a depth of 28 fèet. No further remedial action
is proposed for the soil beneath the formerUST pit.
3.0 GEOLOGY/HYDROGEOLOGY
Soils beneath the site consist of alluvial material derived from the Sierra Nevada to the
east and the Tehachapi Mountains to the south. This heterogeneous section of
Pleistocene and Pliocene alluvium is approximately 5,000 feet thick in the Bakersfield
area and is composed of unconsolidated sand, gravel, silt, clayey sand, and clay.
Observations made at the time of the Phase II investigation indicated that the upper 3 to
4 feet of soil was composed of silty sand underlain by a section of relatively massive
unconsolidated fine- to coarse-grained sand. Pliocene-Pleistocene continental clastic
deposits overlie the Tertiary basement. According to the Kern County Water Agency (Kern
County Water Agency Water Supply Report, 1991) the depth to ground water beneath the
project site is approximately 185 feet bgs.
4.0 REMEDIATION OBJECTIVES
The concentrations of TPH-G and BTEX remaining in the site soils after a period of
remediation are expected to reach an asymptotic concentration (relatively constant
C:\UNOCAL\7048WKPN.DFT121394L

e
-
concentrations over time, following a period of progressive reduction in concentration).
The concentrations are expected to be below' the cleanup criteria. However, if the
hydrocarbon concentrations remain above the allowable limits and no significant reduction
in the concentrations has occurred over a period of two months, the Bakersfield Fire
Department will be petitioned to terminate operation of the remediation system.
5.0 REMEDIATION ALTERNATIVES
Several technologies were considered for this site. Excavation was determined to be the
most costly alternative and would cause major site disruption. Excavating the affected soil
to the extent required to remove all the TPH-D-affected soil would require removal of
dispenser island 3 and the canopy and could potentially undermine the nearby sidewalk
unless shoring is used. Therefore, other remediation technologies were considered for the
TPH-D-affected soil at this site. Excavation of the impacted soils beneath dispenser
island 1 would require the removal of the dispenser island and canopy. Consideration of
the need for shoring or removal of the station building (approximately 20 feet from island
1) would also be required. Therefore, alternate remediation technologies have been
considered for the TPH-G-affected soil at this site.
Vapor extraction is a proven, cost-effective method to remediate TPH-G-affected soil and
it can be used in conjunction with several vapor abatement technologies (e.g., carbon
adsorption, catalytic oxidation, or thermal oxidation). Vapor extraction technology is
generally used to remove volatile petroleum hydrocarbons from soil by mechanically
drawing or venting air through the soil matrix. Vapor extraction has the advantage of
being capable of affecting soil beneath pavement, buildings, and utilities, without major
site disruption. A potential disadvantage of vapor extraction is that the performance can
be adversely affected by low permeability zones within the soil and nonuniform
stratification. However, the soils at the subject site appear to be well suited for soil vapor
extraction, provided that the screened intervals are appropriately selected for the SVE
wells (see Section 5.0).
5.1 DISPENSER ISLAND NUMBER 1
Vapor extraction technology is proposed for the remediation of TPH-G-affected soil
beneath dispenser island 1. Based on the lithology described in boring logs from
previous site investigations (GeoResearch, 1993b) and GeoResearch's experience with
similar sites in the area, vapor extraction is a viable alternative for this site.

5.2 DISPENSER ISLAND NUMBER 3
Vapor extraction technology is also proposed for use to accelerate the bioremediation of
the TPH-D-affected soil beneath dispenser island 3. The initial benefit of this technology
for the TPH-D plume beneath dispenser island 3 will be to remove the more volatile
fraction of the petroleum hydrocarbons within the TPH-D-affected soil. During the
removal of the more volatile fraction, oxygen-rich air containing moisture from the
surrounding soil will be drawn over the affected soil to enhance in situ bioremediation.
The final products of bioremediation are carbon dioxide and water. Removal of petroleum
hydrocarbon vapors and carbon dioxide within the affected soil matrix and inducing the
flow of moist, oxygen-rich air through the affected soil matrix via the bioventing process
will enhance bioremediation.
The United States Air Force bioventing initiative (Air Force Center for Environmental
Excellence, 1994) evaluated 49 sites for bioremediation. Currently 39 systems are
running through out the United States. The Air Force concluded the following:
1. Aeration by injection or extraction is possible at most sites,
2. Biological respiration has been observed at all sites,
3. Natural nutrients are available at most sites, and
4. Soil moisture content is adequate at most sites.
Biodegradation rates between 0.4 to 20 milligrams of petroleum hydrocarbon per kilogram
of soil per day have been observed using bioventing. The petroleum hydrocarbons in the
affected soils tested by the Air Force include diesel, jet fuel, kerosene, and gasoline.
An advantage of bioremediation using bioventing is that it is a low-cost alternative
applicable in areas where excavation is not considered feasible. A disadvantage of
bioremediation is that remediation to the desired cleanup levels may take 2 to 5 years.

5.3 FORMER UST PIT
No further action is proposed for the soil beneath the former USTs based on the
discussion in Section 2.3.
6.0 REMEDIATION SYSTEM DESIGN
The remediation system that is proposed for vapor extraction/bioventing of the TPH-G-
and TPH-D-affected soil will consist of vapor extraction wells, a vapor conveyance
system, a 100-standard-cubic feet per minute (sctm) to 200-scfm blower, a moisture
knock-out pot, and two granular activated carbon (GAC) adsorption vessels with a
C:\UNOCAL\7048WKPN.DFT121394L

-
capacity of 1,000 to 2,000 pounds each, placed in series. Three vapor extraction wells
will be used. Two 2-inch vapor extraction wells will be used to induce air flow through the
TPH-G-affected soil beneath dispenser island 1. These wells will be of the double-
completion type; with one shallow well and one deep well within a single borehole. The
shallow wells will be completed between approximately 5 feet and 23 feet bgs; and the
deep wells will be completed between approximately 27 feet and 45 feet bgs. One single-
completion 2-inch vapor extraction well (VE3), completed between approximately 3 feet
and 25 feet bgs, will be in the TPH-D-affected soil beneath dispenser island 3. Proposed
vapor extraction well locations are shown in Figure 5.
6.1 VAPOR CONVEYANCE PIPING SYSTEM
Each vapor extraction well will be manifolded to the vapor extraction system using
individual 2-inch-diameter, schedule 40 polyvinyl chloride (PVC) pipe. The conveyance
piping will be placed at grade. from VE1 S, VE1 0, VE2S, and VE2D (S=shallow, D=deep)
will be aboveground piping.
6.2 VAPOR TREATMENT SYSTEM
6.2.1 Description of Vapor Treatment System
The five 2-inch vapor conveyance lines will be manifolded to a 3-inch inlet manifold. The
inlet manifold will be piped to a free-moisture knock-out pot and then to two 1,000- to
2,000-pound granular activated carbon (GAC) vessels for treatment of the petroleum-
hydrocarbon-laden air. The carbon within each vessel will be removed and rebedded as
required. The two GAC vessels will be connected, using flexible piping, in series on the
suction side of the 100- to 200-scfm extraction blower. An off-the-shelf, commercially
manufactured vapor extraction blower package will be used. Unocal currently owns and
operates many such blowers. Upon approval of this workplan, and prior to submittal of
the permit application for the Authority to Construct from the San Joaquin Valley Unified
Air Pollution Control District (SJVUAPCD), a blower currently owned by Unocal will be
specified or a new blower will be selected.
6.2.2 Process Flow Description
The process flow will consist of extracting hydrocarbon-laden air from the soil through the
vapor extraction wells and piping it towards the vapor extraction/treatment system through
a vapor conveyance system. The extracted air passes through a free-moisture knock-out
C:\UNOCAL\704BWKPN.DFT121394L

~ -
'~
pot to remove entrained moisture. Then extracted air passes through two 1,000- to 2,000-
pound GAC vessels before entering the suction of the 100- to 150-scfm blower for
discharge to the atmosphere through a stack fitted with a rain cap. Figure 6 presents the
process flow diagram for the proposed vapor extraction/bioventing system. The blower
will be equipped with an hour meter (not capable of being reset) to document the duration
of operation.
Each branch of the inlet manifold will contain a flow control valve and a sample port. The
flow control valve will be used to control the flow through each branch. The sample ports
will be used for collection of samples to measure the vapor concentration within each
branch. Sample ports will also be located upstream of the first GAC vessel, downstream
of the first GAC vessel (upstream of the second GAC vessel), and downstream of the
second GAC vessel at the blower discharge. The sample ports in each branch of the
inlet manifold will also be used to measure the velocity of the extracted vapor in each
branch using an anemometer. The flow rate in each branch will be calculated from the
extracted vapor velocity measured in each branch.
6.2.3 Location of Vapor Treatment System
The proposed location of the vapor treatment system is shown in Figure 5. The system
will be located under the existing canopy above dispenser island 1. The discharge of the
vapor extraction blower will be piped to approximately 3 feet above the canopy for
discharge to the atmosphere.
A chain-link enclosure will be constructed around the inlet manifold and
extraction/treatment system to secure the equipment against vandalism and unauthorized
entry. The dimensions of the enclosure will be approximately 15 feet wide by 20 feet long
and 6 feet high. The enclosure will have a double swinging access gate at one side and
vertical privacy slats in the gates and the three other sides.
6.2.4 Operating Conditions
The maximum capacity of the vapor extraction/treatment system will be 100- to 200-scfm.
The system will treat both the TPH-D-affected soil beneath dispenser island 3 and the
TPH-G-affected soil beneath dispenser island 1 as described below.
6.2.4.1 Dispenser Island Number 1 - Vapor Extraction
The balance of the capacity of the vapor extraction/treatment system will be' used for the
vapor extraction and treatment of the TPH-G-affected soils beneath dispenser island 1
via four wells (two double-completion wells) within the TPH-G plume. The flow rate will

e
be adjusted using the flow control valves to optimize the mass of petroleum hydrocarbons
extracted. The amount of flow from each well will be periodically varied to change the
air flow pattern within the soil and prevent the development of stagnant zones.
The proposed operating schedule for this portion of the remediation system is 24 hours
per day, 7 days per week, 52 weeks per year. There will be occasional downtime for
carbon change-outs and maintenance.
6.2.4.2 Dispenser Island Number 3 - Vapor Extraction/Bioventing
Flow from the single-completed 2-inch-diameter vapor extraction well within the TPH-D
affected soil beneath dispenser island 3 will be adjusted at the inlet manifold to provide
between 5 and 15 scfm of flow. The low flow rate will allow for removal of the volatile
fraction of the TPH-D. This flow rate will also provide oxygen-rich air for bioremediation
of the less volatile hydrocarbons within the TPH-D plume.
The proposed operating schedule for this portion of the remediation system is 24 hours
per day, 7 days per week, 52 weeks per year. There will be occasional downtime for
carbon change-outs and maintenance.
7.0 REGULATORY COMPLIANCE
7.1 PERMITTING REQUIREMENTS
The Planning Department of the City of Bakersfield requires a permitting process that
involves submitting an application form and supporting documents (e.g., construction
drawings for the remediation system, vapor conveyance system, and enclosure) to the
Planning Department for review and approval.
The SJVUAPCD requires that an Authority to Construct (A TC) permit application be
completed and approved prior to beginning construction of the remediation system. Once
the A TC permit has been approved and the remediation system has been constructed,
a Permit to Operate (PTO) application must be completed and approved prior to system
operation.

7.2 MONITORING AND REPORTING
7.2.1 Equipment Monitoring
The proposed carbon-based vapor extraction system will be monitored and maintained
per SJVUAPCD monitoring requirements. The periodic monitoring of the vapor extraction
system will include sampling of the extracted vapor from each extraction well, the total
system influent stream (to the first carbon vessel), effluent from the first carbon vessel,
and effluent from the second carbon vessel using portable analyzer probes such as a
flame ionization detector (FID) or a photoionization detector (PI D). The FID or PID
readings will be recorded in the system operation log. Periodic monitoring will also
include recording the blower run time and the measurement of the total system influent
flow rate, and the flow rate from each extraction well. The data will be entered into a
computer database to calculate the total mass of petroleum hydrocarbons extracted.
7.2.2 Emission Compliance Monitoring
The periodic monitoring data will be used to guide the operation and maintenance of the
vapor extraction system. The emission compliance monitoring of the vapor treatment
system will be in accordance with the emission requirements and monitoring schedule
that will be established by the SJVUAPCD. It is expected that the SJVUAPCD will require
concentration measurements at the combined system influent and at the effluent of the
vapor treatment system according to the following schedule:
· First Week:
Once a day, the combined influent and effluent of the vapor treatment
system will be monitored for volatile organic concentration using field
instrumentation.
· Second Week through First Month:
Once a week, the combined influent and effluent of the vapor treatment
system will be monitored for volatile organic concentration using field
instrumentation.
· After First Month:
Twice a month, the combined influent and effluent of the vapor treatment
system will be monitored for volatile organic concentration using field
instrumentation.

7.2.3 Reporting
Results obtained from the emission compliance monitoring will be compiled in a quarterly
report for submittal to the appropriate agencies as required. It is expected that the
SJVUAPCD will require quarterly monitoring reports submitted presenting analytical
measurement and emissions calculations. Quarterly status reports will be prepared and
submitted tò the Bakersfield Fire Department detailing the progress during each quarter.
7.3 TERMINATING THE SOIL VAPOR EXTRACTION OPERATION
7.3.1 Evaluation of Remedial Effectiveness
The concentrations of hydrocarbons extracted from the soil are highest during the first few
weeks, decrease gradually over time, and eventually approach a minimum, asymptotic
concentration. In the case of the more volatile constituents, such as benzene, this
asymptotic value may reach non detectable concentrations. Routine monitoring data will
be used to measure (1) the effectiveness of the Remediation system in removing
petroleum hydrocarbons from the soil, and (2) when the mass extraction rates decrease
to near zero. Once it has been determined that no significant reductions in the
hydrocarbon concentrations have occurred over two monthly monitoring periods,
confirmation soil sampling will be initiated at the site to verify the completion of the
remediation in preparation for deactivation of the soil vapor extraction portion of the
remediation system.
The rate of biodegradation of larger, less volatile diesel range hydrocarbons is initially
expected to increase as oxygen and moisture are supplied to the subsurface, but then
decrease to near zero as fewer hydrocarbons are available. To evaluate the effectiveness
of the bioremediation portion of the remediation system, in situ biorespiratory tests (BRTs)
will be performed. An initial BRT will be performed, followed by a BRT every 6 months.
The BRT will be performed to estimate the biorespiration rate in terms of pounds of
petroleum hydrocarbons destroyed per hour. The test will be performed by saturating the
soil with air and monitoring the decreasing oxygen concentration and increasing carbon
dioxide concentrations over 3 to 5 days. The vapor extraction system will not be
operating during the BRT. When the rate of bioremediation decreases, and it has been
determined that no further significant reductions in the hydrocarbon concentrations have
occurred in response to the bioventing system, confirmation sampling will be initiated at
the site in preparation for deactivation of the bioventing portion of the remediation system.

7.3.2 Confirmation Sampling
Three to five soil borings will be drilled for the collection of confirmation samples. The soil
borings will be drilled to depths of 25 feet beneath dispenser island 3 and to 45 feet
beneath dispenser island 1. Representative samples from those collected will be
analyzed for TPH-G and BTEX (island 1) and TPH-D (island 3). The soil borings will be
within and around areas that have been shown in previous investigations to contain high
concentrations of hydrocarbons (GeoResearch, 1993b) to determine the effectiveness of .
vapor extraction and bioremediation in these areas.
Analyses for TPH-G and TPH-D will be completed according to California Department of
Health Services methods and BTEX analyses shall be completed according to U.S. EPA
Method 8020. Once confirmation sampling has been completed and the laboratory
results have indicated that the hydrocarbon concentrations are at an acceptable level, the
vapor extraction and/or bioremediation system will be terminated. A report summarizing
the results of remedial system operation and soil confirmation sampling will be prepared
and submitted to the Bakersfield Fire Department with a request for formal closure of the
site.

RE: Addendum to Report of Subsurface Site Investigation, Unocal Service
Station #7048, 2518 White Lane, Bakersfield, California. GeoResearch
Project Number 937000703.
Dear Mr. Ralston:
In response to your request, this letter provides a presentation and discussion of remedial
alternatives for soils on the subject property which have been found to contain gasoline
and diesel fuel. This letter is considered an addendum to the above-referenced report
dated October 28, 1993. Upon your request, this letter can be reformatted for direct
submittal to the Bakersfield Fire Department.
SITE BACKGROUND
Unocal plans to sell the property with the existing service station building and canopies
in -place. Unocal closed the service station in 1992 and removed all USTs and fuel lines
in September, 1992. A Tank Closure Report prepared by GeoResearch dated February
22; 1993 was submitted to Unocal and the Bakersfield Fire Department. Based on the
findings of the investigation presented in the above-referenced subsurface site
investigation report, two areas of the site with significant concentrations of petroleum
hydrocarbons have been identified. Site assessment results are summarized as follows:
o Site soils are clean well-sorted sands and silty sands to the base of
identified contamination. The depth to ground water is estimated to be
approximately 180 feet.

o Diesel fuel has been identified beneath the western dispenser island at
concentrations of up to 12,000 mg/kg. The diesel appears limited to a
depth of 20 feet with an estimated impacted soil volume of 100 to 200 cubic
yards. Excavation of the diesel fuel would threaten the support of the island
canopy and could require shoring along the adjacent city sidewalk.
o Gasoline has been identified beneath the northernmost dispenser island
south of the station building. TPH-G concentrations of up to 4,500 mg/kg
have been identified at depths of up to 45 feet.
o In response to a review of the site assessment report, the Bakersfield Fire
Department has requested that Unocal submit a plan for site remediation.
REMEDIAL ALTERNATIVES
The following remedial alternatives have been considered for application to the soils of
the subject property:
0 No action,
0 Excavation,
0 Soil Vapor Extraction,
0 Bioventing.
A preliminary evaluation of the advantages and disadvantages of each alternative is
included. Other remedial options may be feasible, based on equipment and technologies
available to Unocal at this time. All site remediation work should be pertormed in
accordance with a work plan approved by the Bakersfield Fire Department and other
pertinent agencies.

NO ACTION
Based on the concentrations of petroleum hydrocarbons identified and the request for
remedial options from the Bakersfield Fire Department, a true no-action alternative is not
considered feasible. In the event that direct mitigation of petroleum hydrocarbons is not
conducted, a risk assessment should be conducted to estimate the potential risk to
human health and the environment. This could be combined, if warranted, with capping
of the site and limitations placed on future site use. If Unocal wishes to prepare the
property for sale with no restrictions or conditions which could result in future environ men-
tal liability, then the no action alternative is not considered feasible.
EXCAVATION
Complete excavation of the soils ·containing petroleum hydrocarbons would require the
removal or temporary shoring of both canopies. Existing water and electrical utilities
could be disrupted. Gasoline vapors could be a significant health and safety concern in
soils directly beneath the south island. Shoring of the site building could be necessary
for the gasoline excavation. Shoring of the sidewalk may be necessary in the case of the
diesel excavation.
Excavation of the soils impacted by diesel fuel appears to be a reasonable alternative.
While bioventing (discussed below) could be a less expensive alternative, excavation
would be much faster.
Excavation may not be a viable remedial alternative for the soils impacted by gasoline.
The depth of excavation required could require extensive engineering controls to safely
complete. The physical hazards presented by excavation of soils with a high volatile
content and the opportunity for volatilization of gasoline into the environment further
decrease both the desirability of this alternative and the permitability. Costly measures
to minimize volatilization of gasoline from excavated soils may be required for site safety
reasons as well as for compliance with air quality requirements.

SOIL VAPOR EXTRACTION
Based on the apparent high permeability of soils encountered on the subject property,
soils containing gasoline can probably be remediated to below standard detection limits
for TPH-G and benzene via the operation of a soil vapor extraction system (VES).
Treatment of the extracted vapors may be completed utilizing activated carbon, an
internal combustion engine, or thermal/catalytic oxidation. An appropriate extraction rate
and selection of the type of treatment unit can be made based on a soil vapor extraction
test or on presently-available data from previous site assessment activities. Based on
GeoResearch's experience with soil vapor extraction in the Central Valley and with the
soil conditions observed on the subject property, a vapor extraction test is probably
unnecessary.
Based on a preliminary analysis of existing data, a thermaVcatalytic oxidation unit of 200
to 250' cfm capacity should be appropriate for the subject property. Based on an
estimated TPH-G mass in site soils of 1770 pounds, the time required for remediation of
gasoline-impacted soils is conservatively estimated to be 6 to 9 months.
Soil vapor extraction is likely to remove only 30 to 50% of the diesel fuel present beneath
the western dispenser island; however, supplemental hydrocarbon degradation by
bacterial action may be induced by the introduction of oxygen into site' soils (see
bioventing - discussed below).
BIOVENTING
If site conditions are amenable, the introduction of air (at a low rate) into the subsurface
can promote the growth of soil bacteria which can oxidize the petroleum hydrocarbons
present. This technique, known as bioventing, provides for the simulation of in-situ
biodegradation by the introduction of oxygen. Bioventing is simply a means of introducing
oxygen to the subsurface, in the area of the hydrocarbon release, to facilitate the natural
degradation of petroleum hydrocarbons by the existing biological population.
The feasibility of bioventing at this site is dependent upon the presence of a population
of microorganisms capable of degrading gasoline, essential nutrients required by the
microbes, high soil moisture, and sufficient soil permeability to facilitate the supply of
oxygen to the microbes. Microbial populations with the capacity to degrade petroleum

hydrocarbons are relatively ubiquitous and are commonly well developed in areas of old
hydrocarbons releases, such as this site. However, the lack of oxygen frequently results
in the organisms residing in as essentially dormant stage. Most soils contain sufficient
concentrations of the essential nutrients required by these microbes, primarily nitrogen
and phosphorous. Soil moisture can be conserved by utilizing a low air flow rate. The
high permeability expected of site soils would facilitate the introduction of water and soil
nutrients, if required.
Based on the concentration of hydrocarbons at this site (using the maximum TPH-G and
TPH-D concentration of 4,500 mg/kg and 12,000 mg/kg, respectively), the time required
for complete remediation by bioventing is estimated to be 1.5 to 3 years for the gasoline-
impacted soils and 3 to 6 years for the diesel-impacted soil. However, the clean up time
may be decreased substantially if regulatory acceptance for clean up goals in excess of
1,000 mg/kg for TPH-G and TPH-D can be negotiated. The cost of remediation by
bioventing is expected to be less than for soil vapor extraction or excavation (or some
combination of the two). However, bioventing' costs could escalate if the remediation
requires substantially more time than estimated.
SELECTION AND IMPLEMENTATION OF A REMEDIAL ALTERNATIVE
Existing site assessment data is adequate to evaluate the no action, soil vapor extraction,
and excavation alternatives. Bioventing is probably feasible; however, the collection of
additional soil samples for the completion of a biotreatability study is necessary to
demonstrate the suitability of site soils for this type of remediation.
Both soil vapor extraction and bioventing, if selected, will require the installation of
injection and/or extraction and monitoring wells within the vadose (unsaturated) zone.
Either horizontal or vertical wells could be utilized (or some combination of the two);
however, the limited horizontal extent of identified petroleum hydrocarbons would limit any
advantage to be realized by the use of horizontal wells.
Upon receipt of direction from Unocal as to the desired remedial alternative or
combination of remedial alternatives, a remedial action plan can be prepared and
submitted within six weeks. Upon approval from Unocal and the Bakersfield Fire
Department, the necessary permits can be secured. Depending upon the method of
remediation selected, permits should be available in 1 to 4 months. Installation of the

Dear Mr, Huey:
This letter is written in response to your letter dated April 28,
1994 (received May 3, 1994) regarding the site Characterization report
for the above-mentioned station, As we have previously discussed,
both today and after the receipt of your December 6, 1993 letter, this
report was strictly an assessment report, not a corrective action plan.
As we also discussed, Unocal readily acknowledges that petroleum
hydrocarbons exist in the subsurface at this site and the need for
further work. Unocal and our consultant have been evaluating cost-
effective, remedial alternatives and will submit an addendum to our
site Characterization report to comply with your request by June 1,
1994 (as we agreed during our conversation today).
Also, as per your request, Unocal will submit all future correspondence
to Mr, Howard Wines of your department. Unocal will arrange to meet
with Mr, Wines in the future to discuss the specifics of our remedial
approach for the subject site,
Should you have any questions or concerns regarding this matter, please
feel free to contact me at (510) 277-2311,
sincerely,

Dear Mr. Ralston:
In response to your request. this letter provides a presentation and discussion of remedial
alternatives for soils on the subject property which have been found to contain gasoline
and diesel fuel. This letter is considered an addendum to the above-referenced report
dated October 28, 1993. Upon your request, this letter can be reformatted for direct
submittal to the Bakersfield Fire Department.
SITE BACKGROUND
Unocal plans to sell the property with the existing service station bUilding and canopies
¡n.place. Unocal closed the service station in 1992 and removed all USTs and fuel lines
in September, 1992. A Tank Closure Report prepared by GeoResearch dated February
22. 1993 was submitted to Unocal and the Bakersfield Fire Department. Based on the
findings of the investigation presented in the above-referenced subsurface site
investigation report, two areas of the site with significant concentrations of petroleum
hydrocarbons have been identified. Site assessment results are summarized as follows:
o Site soils are clean well-sorted sands and silty sands to the base of
identified contamination. The depth to ground water is estimated to be
approxìmately 180 feet.

o Diesel fuel has been identified beneath the western dispenser island at
concentrations of up to 12,000 mglkg. The diesel appears limited to a
depth of 20 feet with an estimated impacted soil volume of 100 to 200 cubic
yards. Excavation of the diesel fuel would threaten the support of the island
canopy and could require shoring along the adjacent city sidewalk.
o Gasoline has been identifi'ed beneath the northernmost dispenser island
south of the station building. TPH,G concentrations of up to 4,500 mglkg
have been identified at depths of up to 45 feet.
o In response to a review of the site assessment report, the Bakersfield Fire
Department has requested that Unocal submit a plan for site remediation,
REMEDIAL ALTERNATIVES
The following remedialaltematives have been considered for application to the solis of
the subject property:
0 No action,
0 Excavation.
0 Soil Vapor Extraction,
(
0 Bioventing.
A preliminary evaluation of the advantages and disadvantages of each altemative is
included. Other remedial options may be feasible, based on equipment and technologies
available to Unocal at this time. All site remediation work should be performed In
accordance with a work plan approved by the Bakersfield Fire Department and other
pertinent agencies.

NO ACTION
Based on the concentrations of petroleum hydrocarbons identified and the request for
remedial options from thè Bakersfield Fire Department, a true no-action altemative is not
considered feasible. In the event that direct mitigation of petroleum hydrocarbons is not
conducted, a risk assessment should be conducted to estimate the potential risk to
human health and the environment. This could be combined. if warranted. with capping
of the site and limitations placed on future site use. If Unocal wishes to prepare the
property for sale with no restrictions or conditions which could result In future environmen-
tal liability , then the no action alternative is not considered feasible,
EXCAVATION
Complete excavation of the soils containing petroleum hydrocarbons would require the
removal or temporary shoring of both canopies. Existing water and electrical utilities
could be disrupted, Gasoline vapors could be a significant health and safety concem in
soils directly beneath the south island. Shoring of the site bUilding could be necessary
for the gasoline excavation. Shoring of the sidewalk may be necessary in the case of the
diesel excavation.
Excavation of the soils impacted by diesel fuel appears to be a reasonable alternative.
While bioventing {discussed below} could be a less expensive alternative, excavation
would be much faster.
Excavation may not be a viable remedial alternative for the soils Impacted by gasoline.
The depth of excavation required could require extensive engineering controls to safely

decrease both the desirability of this alternative and the permitability. Costly measures

Re: Site Characterization for former Unocal Station #7048 located at 2518 White Ln
Dear Mr. Ralston:
A review of the correspondence file shows that you were last notified on
December 6, 1993 and were then advised of the following:
"This office has review [sic] the Site Characterization Report for the
Unocal Service Station No. 7048 located at 2518 White Lane. This
report has been rejected because it is incomplete.... Please
complete the assessment and return it to this office within 15
working days. If you have any questions, please call me at (805)
326-3979."
Unfortunately, I can't find anything else in your file that indicates you have
complied with this requirement. I'm especially alarmed because so much time has
elapsed since our last contact.
Please help me update your file by responding within 14 days, in writing, as
to how you have addressed the previous code violation, If you've had difficulties with
compliance, I'll need to know that as well. I'm willing to work with you toward gaining
compliance with the law, but we do need to resolve this issue.
Very truly yours,

RE: Site Characterization of the property located at 2518 White Lane
Dear Mr. Ralston:
This office has review the Site Characterization Report for the Unoc21 Service Station No.
ì048 located at 2518 White Lane. This report has been rejected because it is
incomplete.
Significant hydrocarbon concentrations have been detected, as well as Toluene, Ethyl
Benzene and Xylene. Your report however, does not include any form of risk appraisal,
eVallJation of mitigation alternatives or recommendation of mitigation measures. The soii
testing and analytical results appear to be adequate (depending upon your mitigation
proposal). However, you must address this contamination problem, and address a time
table for completing this project.
Please complete the assessment and return it to this office within 15 working days, if
you have any questions, please call me at (805) 326-39'79.

EXECUTIVE SUMMARY
A Phase II site investigation was conducted in August of 1993 at Unocal Service Station
No. 7048 located at 2518 White Lane, Bakersfield, California (Figure 1). The purpose of
the investigation was to determine the vertical and lateral extent of petroleum
hydrocarbons which were identified at the site when the underground fuel storage tanks
(USTs) and product lines were removed (GeoResearch, February 22, 1993).
According to laboratory reports, concentrations of TPH-D as high as 12,000 mg/kg were
identified beneath dispenser island No.3. at 8 feet bgs. Soil samples collected at 13, 18,
and 23 feet bgs contained TPH-D at 8,500, 4,200, and 1.0 mg/kg, respectively. Soil
boring SB5, drilled 15 feet west of the diesel dispenser, did not contain evidence of
hydrocarbons. It is estimated that on the order of 100 to 200 cubic yards of soil beneath
dispenser island No. 3 contains diesel fuel. Excavating the affected soil to the extent
required to remove all the diesel fuel would require removal of the dispenser island and
canopy and could potentially undermine the nearby sidewalk, unless shoring is utilized.
Field observations and laboratory analysis of soil collected beneath island No.1 indicates
at least two source areas of gasoline release, one at each end of the island. The
penetration of gasoline appears to have been limited primarly to depths of no more than
approximately 40 feet bgs, at a concentration of up to 5,400 mg/kg. Traces of BTEX
constituents of were found to 48 feet bgs. Clean samples were obtained at 58 and 63
feet. It appears that hydrocarbons leaking from the west end of the island may have
been impeded by a change in lithology from silty sand to sandy silt. It is estimated that
on the order of 500 cubic yards of soil beneath dispenser island NO.1 contain significant
concentrations of gasoline.
Excavation of the impacted soils beneath dispenser island No. 1 would require the
removal of the dispenser island and canopy. Consideration of the need for shoring or
removal of the station building (approximately 20 feet from island No.1) would also be
required.
Soil boring SB4, drilled in the former UST pit, encountered fill soils from the UST removal
activities to a depth of 28 feet. Analysis of the 30-foot sample for diesel revealed a
concentration of 350 mg/kg TPH-D. Significant concentrations of hydrocarbons were not
detected below a depth of 30 feet.
Based on the analysis of soil samples collected upon the completion of excavation of soil
following UST removal, the aerial extent of any remaining hydrocarbons in soils in the
former UST pit area is expected to be small. The results of this investigation suggest a
very limited vertical extent restricted to less than 35 feet bgs.

1.0 INTRODUCTION
A Phase II site investigation was conducted in August of 1993 at Unocal Service Station
No. 7048 located at 2518 White Lane, Bakersfield, California (Figure 1). The investigation
was completed in accordance with a work plan dated February 10, 1993, which was
submitted to Unocal and authorized by Mr. Ed Ralston. Subsequently, the work plan was
submitted to the City of Bakersfield, Fire Department (BFD) and authorized by Mr. Ralph
Huey (Appendix A). The purpose of the investigation was to determine the vertical and
I.ateral extent of petroleum hydrocarbons which were identified at the site when the
underground fuel storage tanks (USTs) and product lines were removed (GeoResearch,
February 22, 1993).
2.0 SITE BACKGROUND
According to a Phase I Environmental Site Assessment of the site conducted by PHR
Environmental Consultants, Inc, (PHR, October, 1992), the site was formerly occupied by
a Thrifty self-serve station built in 1981. Unocal purchased the station in May of 1984.
At the time of the purchase, a 15,OOO-gallon, 10,000-gallon, and two 6,000-gallon USTs
as well as a 550-gallon waste··oil UST were present on the site. An additional 12,000-
gallon gasoline UST was also present; however, the time of it's installation is unknown.
According to the Phase I report, in 1984 the two 6,ODO-gallon USTs were manifolded
together and backflow valves and leak detectors were installed. In 1985, the manifold
valve stuck open and fuel from one of the USTs was pumped into the other and out the
fill port on to the surface. An unknown quantity of fuel was lost. Subsequently, an
investigation was conducted by Consolidated Testing Laboratory of Bakersfield, California
which included drilling a 40 foot boring between the easternmost 6,00D-gallon tank and
the adjacent 10,000-gallon tank. Soil samples from the boring were tested only for
benzene, toluene, ethylbenzene, and total xylenes (BTEX), EDB, and isopropylbenzene.
None of these parameters were detected below 10 feet below ground surface (bgs).
Neither the Consolidated report nor the Phase I report clearly indicated whether the fuel
spilled was gasoline or diesel.
In September of 1992, GeoResearch observed the removal of the USTs and associated
product lines at the site. Soil samples were collected and laboratory analysis was
completed beneath the USTs, fuel dispensers, product lines and former vehicle hoists.
A TPH-D concentration of 13,000 mg/kg was identified adjacent to the diesel dispenser
(south end of dispenser island No.3) at a depth of 11 feet bgs. Further investigation was
not practical at that time due to the risk of loose and caving sands undermining the island
and the nearby canopy support.
According to laboratory reports, concentrations of TPH-D and TPH-G of 630 and 250
mg/kg, respectively, were identified at the west end of island NO.1 at 6 feet bgs. Soil

samples ceUected near the east end of island No. 1 were reported to contain TPH-D and
TPH-G of up to 630 and 9,700 mg/kg, respectively. Only slight concentrations of toluene
and/or total xylenes were detected in the soil samples collected at 11 feet bgs at these
locations. However, hydrocarbon odors were quite strong to a depth of 11 feet bgs and
additional soil sample collection was impractical with the available equipment due to the
caving sands.
Soil samples were collected from beneath the gasoline/diesel USTs. Those soils which
were identified as containing significant concentrations of petroleum hydrocarbons were
excavated and stockpiled on-site. Confirmation soil samples collected from beneath the
USTs and from the sidewalls of the UST excavation adequately verified the removal of
petroleum hydrocarbons in most of the pit area. However, additional excavation was not
feasible beneath diesel USTs where low concentrations of TPH-D (33 mg/kg) were
identified.
Approximately 920 cubic yards of imported soil was utilized to backfill the UST excavation
pit up to 18 inches below grade. The remaining 18 inches was backfilled with on-site
soils (GeoResearch, February 22, 1993), as authorized by the Bakersfield Fire
Department.
3.0 GEOLOGY/HYDROGEOLOGY
Soils beneath the site consist of alluvial material derived from the Sierra Nevada to the
east and the Tehachapi mountains to the south. This heterogeneous section of
Pleistocene and Pliocene alluvium is on the order of 5,000 feet thick in the Bakersfield
area and is composed of unconsolidated sand, gravel, silt, clayey sand and clay.
Pliocene-Pleistocene continental clastic deposits overlie the Tertiary basement. The
Tertiary basement, composed of granitic and metamorphic rocks, underlies the clastic
section at a depth on the order of 15,000 feet below ground surface (Hackel, 1960).
Observations made at the time of the investigation indicated that the upper three to four
feet of soil was composed of silty sand underlain by a section of relatively massive
unconsolidated fine to coarse-grained sand. According to the Kern County Water Agency
(Water Supply Report, September 1991, District 41) the depth to ground water beneath
the project site is approximately 185 feet bgs.
4.0 PROCEDURES AND OBSERVATIONS
Six soil borings were completed on the site on August 10th and 11 th, 1993. Five of these
borings were completed by hollow-stem auger methods and one was completed by hand
auger methods (Figure 2). The work was completed in accordance with a site-specific
health and safety plan~

Drilling services were provided by S/G Testing Laboratories, Inc. of Lompoc, California.
A truck-mounted CME 75 drill rig equipped with 6-inch and 8-inch continuous flight hollow-
stem augers was utilized for drilling. Prior to drilling, the borings were hand augered to
a depth of 5 feet below ground surface (bgs) to confirm that no underground facilities
were present in the boring locations. Underground Service Alert (USA) was contacted
48 hours prior to drilling in order to locate any public utilities on site. All borings were
completed in accordance with standard GeoResearch procedures (Appendix B) and
backfilled with cement/sand slurry.
Drill cuttings were monitored with an h-nu systems organic vapor analyzer (OVA) with a
10.2 electron volt probe in order to obtain a preliminary indication of the presence of
volatile hydrocarbons prior to laboratory analysis. All drill cuttings were stockpiled on and
covered with plastic on the east side of the station building. Drill cuttings containing field
evidence of petroleum hydrocarbons were stockpiled separately. Soil borings were
logged by a GeoResearch geologist under the supervision of California Certified
Engineering Geologist in accordance with the Unified Soil Classification System and
recorded on Field Log of Boring forms (Appendix C).
Soil samples were collected at 5-foot intervals. Soil samples collected from the hollow-
stem auger borings are identified by SB#-depth (example: SB1-5). Soil samples collected
from the hand augered boring were identified by HA#-depth (example: HA1-5). Soil
samples collected at the site were submitted to GEOTEST of Long Beach, California, a
California Environmental Protection Agency (CAUEPA)-certified laboratory.
4.1 DISPENSER ISLAND No.3
Soil borings SB1 and SB5 were drilled near the former diesel dispenser located on the
south end of dispenser island NO.3 (west of the station building, Figures 2 and 3). Soil
boring SB 1 was angled 20 degrees from vertical beneath the diesel dispenser, through
the projected center of the plume of diesel fuel in soil, to a depth of 48 feet bgs. Soil
boring SB5 was drilled vertically to a depth of 30 feet bgs approximately 15 feet west of
the island near the western property boundary in order to place a constraint on the lateral
extent of diesel fuel in site soils.
Soil collected in boring SB 1 was stained brown and contained strong diesel odors from
3 feet bgs to 15 feet bgs. Soil between 8 and 13 feet bgs appeared saturated with diesel.
Neither Soil staining nor hydrocarbon odors were noted below 25 feet bgs. Soils
observed in soil boring SB5 did not contain field evidence of hydrocarbons.

4.2 DISPENSER ISLAND No. 1
Soil boring SB2 was drilled 20 degrees from vertical beneath the west end of dispenser
island NO.1 (south of the station building) to a depth of 68 feet bgs. Soil boring SB3 was
angle drilled 10 degrees from vertical beneath the east end of dispenser island No. 1 to
a depth of 65 feet bgs. Hand auger boring HA 1 was drilled approximately 10 degrees
from vertical beneath the canopy support in the center of the island to a depth of 10 feet
bgs (Figures 2 and 4). Individually, these borings were intended to pass through the
center of any plumes of gasoline in soil and define the depth of penetration of gasoline.
In addition, the collective information from all the borings was intended to place a
constraint on the lateral extent of gasoline in site soils.
According to the OVA readings collected, volatile organic compounds (VOCs) were
present in SB2 to depth of 48 feet bgs. The highest concentrations of VOCs (70 ppm)
were detected in soils collected at 23, 28, and 38 feet bgs. No soil staining was observed
in this boring.
VOCs were detected with the OVA in soil boring SB3 from 8 to 55 feet bgs. ThE3 highest
OVA reading (100 ppm) was found in soil collected from 13 and 18 feet -bgs. No soil
staining was observed in this boring.
Soil encountered in hand auger boring HA 1 was hydrocarbon stained from approximately
1 foot bgs to 5 feet bgs. This staining was accompanied by strong gasoline odors. VOCs
were recorded as high as 120 ppm on the OVA at a depth of 10 feet bgs. This boring
could not penetrate below 10 feet bgs due to very loose sands which continually filled the
boring below this depth.
4.3 FORMER UST PIT
Soil boring SB4 was drilled approximately between the two former 6,OOO-gallon diesel
USTs to a depth of 65 feet bgs (Figure 2). Soil in this area had previously been
excavated to a depth of approximately 28 feet bgs when the USTs were removed. This
boring was completed to confirm the removal of significant hydrocarbon concentrations
from the UST pit area. Soil samples were not collected while drilling through this fill soil.
Hydrocarbon odors were noted in this boring from 30 to 35 feet bgs accompanied by VOC
concentrations as high as 150 ppm. Only slight hydrocarbon odors were noted below 35
feet bgs. No soil staining was observed.

4.4 STOCKP-ILED SOIL AND RINSE WATER
Approximately 3 cubic yards of soil were generated during drilling activities at the site.
These soils were stockpiled on and covered with plastic sheeting along the east side of
the station building. Approximately 2 cubic yards of this soil contained field evidence of
petroleum hydrocarbons. This soil was stockpiled separately adjacent to the clean soil.
Approxi'mately 110-gallons of water utilized to steam clean the augers and to
decontaminate the sampling rings was placed in a DOT-approved 55-gallon drums,
labeled, and stored on-site near the east side of the station building.
5.0 LABORATORY RESULTS
Selected soil samples were analyzed by GEOTEST for total petroleum hydrocarbons as
gasoline (TPH-G) and/or total petroleum hydrocarbons as diesel (TPH-D) in accordance
with California Environmental Protection Agency (CAL-EPA) methods (Table 1). Selected
soH samples were also analyzed for BTEX in accordance with United States EPA Method
8020. Descriptions of laboratory analytical methods are included in Appendix D.
Laboratory reports and chain-of-custody documentation are presented in Appendix E.
-^
5.1 DISPENSER ISLAND No. ~
According to laboratory reports, soil collected beneath the south end of dispenser island
No. 3 contains TPH-D concentrations of up to 12,000 mg/kg (8 feet bgs - soil sample
SB1-8, Figure 3). Soil samples collected at 13 and 18 feet bgs (SB1-13 and SB1-18)
contain TPH-D concentrations of 8,500 mg/kg and 4,200 mg/kg, respectively. Soil sample
SB 1-13 was additionally analyzed for BTEX and was found to contain only trace
concentrations of ethylbenzene and total xylenes (no benzene or toluene). A sample
collected at 23 feet bgs (SB1-23) contained 1.0 mg/kg TPH-D. Soil samples collected at
28 and 33 feet bgs in this boring were not found to contain TPH-D.
5.2 DISPENSER ISLAND No. 1
According to laboratory reports, soil collected in boring SB2 at 8 and 13 feet bgs
contained concentrations of TPH-G of 1,100 and 1.9 mg/kg, respectively (Table 1, Figure
4). Soil samples collected in this boring at 18 and 23 feet bgs did not contain TPH-G.
Soil samples collected at 28, 33, and 38 feet bgs contain TPH-G at 8.5, 5,400, and 2,500
mg/kg, respectively. Soil samples collected at 43 and 48 feet bgs did not contain TPH-G,
however, low concentrations of toluene, ethyl benzene, and/or total xylenes were reported.
Two soil samples collected in this boring (SB2-33 and SB2-38) contained a low
concentration of benzene (0.39 mg/kg and 0.67 mg/kg, respectively).

According-:tø.;..lãboratory reports, soil samples collected in soil boring SB3 at 18 and 23
feet bgs contained concentrations of TPH-G of 29 and 1.7 mg/kg, respectively. The 18
foot sample as well as the 48 foot sample contained benzene at 0.012 mg/kg and 0.007
mg/kg, respectively. Samples collected at 23 and 38 feet bgs did not contain benzene;
however, low concentrations of toluene, ethyl benzene, and/or total xylenes were present
(Table 1).
Soil sample HA 1-10, collected at 10 feet bgs in the hand augered boring was reported
to contain TPH-G at 2,700 mg/kg and BTEX of 1.9, 60, 28, and 310, respectively.
5.3 FORMER UST PIT
Based on odors noted during drilling, soil in boring SB4 (drilled in the former UST pit
area) was originally thought to contain gasoline. Several soil samples were analyzed for
TPH-G and only the 30 foot sample was reported with a detectable TPH-G concentration
(2,700 mg/kg). A review of the chromatogram from the TPH-G analysis for soil sample
SB4-30 indicated that the hydrocarbon might be diesel. The sample was reanalyzed for
TPH-D. A TPH-D concentration of 350 mglkg was reported and a review of the
chromatogram demonstrated that the hydrocarbon was diesel fuel.
Trace concentrations of toluene, ethylbenzene, and total xylenes were reported in the 30
and 60 foot samples.
6.0 SUMMARY AND CONCLUSIONS
The vertical extent of diesel fuel and gasoline in soils at Unocal Station No. 7048 have
been defined at several locations. Data has been collected to facilitate the estimation of
the lateral extent of gasoline and diesel fuel and the calculation of impacted soil volumes.
6.1 DISPENSER ISLAND NO.3
According to laboratory reports, concentrations of TPH-D as high as 12,000 mglkg were
identified beneath dispenser island No.3 (8 feet bgs). Soil samples collected at 13,18,
and 23 feet bgs contained TPH-D at 8,500, 4,200, and 1.0 mg/kg, respectively. Soil
boring SB5, drilled 15 feet west of the diesel dispenser, did not contain evidence of
hydrocarbons.
Based on the estimated extent of TPH-D shown in Figure 3 and assuming a symmetrical
distribution in the third dimension, it is estimated that on the order of 100 cubic yards of
soil beneath dispenser island No.3 contains diesel fuel. In the event that the lateral limit
of diesel fuel closely approaches SB5, it is estimated that up to 200 cubic yards of soil

may be impaèted.- The calculations from which these volumes were derived are shown
in Appendix F. These volumes do not include clean overburden soil.
A public right-of-way (sidewalk) is located approximately 15 feet west of the dispenser
island. It has been established that loose and caving sands are present beneath the site.
Excavating the affected soil to the extent required to' remove all the diesel fuel would
require removal of the dispenser island and canopy and could potentially undermine the
sidewalk, unless shoring is utilized.
6.2 DISPENSER ISLAND No. 1
Soil boring SB2, drilled beneath the west end of island No.1, contained a TPH-G
concentration of 1,100 mg/kg at 8 feet bgs. TPH-G concentrations in this boring
decreased to non-detectable levels at 18 and 23 feet bgs. However, TPH-G
concentrations increased again to'5,400 mg/kg andi2,500 mg/kg in soil samples collected
at 33 and 38 feet bgs, respectively. \ Benzene concentrations of 0.39 and 0.67,
respectively, were also present in these samples. Samples collected at 43 and 48 feet
bgs contained concentrations of toluene, ethylbenzene, and/or total xylenes near the
detection limits, but no TPH-G. Soil boring 8B3, drilled beneath the east erid of island
No.1, contained low concentrations of TPH-G at 18 and 23 feet bgs. No TPH-G was
identified below 23 feet bgs. A soil sample collected at 10 feet bgs beneath the canopy
support contained 2,700 mg/kg TPH-G and 1.9 mg/kg benzene.
BTEX concentrations appear to decrease rapidly to zero or near zero between 38 and 43
feet bgs beneath dispenser island NO.1. Only trace amounts of BTEX constituents were
detected below 38 feet bgs and no BTEX was detected below 48 feet.
Field observations and laboratory analysis of soil collected beneath island NO.1 indicates
at least two source areas, one at each end of the island. It appears that hydrocarbons
leaking from the west end of the island may have been impeded by a change in lithology
from silty sand to sandy silt. Based on the estimated extent of TPH-G concentrations
shown in Figure 4 and assuming a symmetrical distribution of each of the two lobes of
the plume in the third dimension, it is estimated that on the order of 500 cubic yards of
soil beneath dispenser island No. 1 contain significant concentrations of gasoline.
Volume calculations are shown in Appendix F.
Excavation of the impacted soils would require the removal of the dispenser island and
canopy. Consideration of the need for shoring or removal of the station building
(approximately 20 feet from island No.1) would also be required.

6.3 FORM(;F-FUST PIT
Soil boring SB4, drilled in the former UST pit, encountered fill soils from the UST removal
activities to a depth of 28 feet. Analysis of the 30-foot sample for diesel revealed a
concentration of 350 mg/kg TPH-D. Significant concentrations of hydrocarbons were not
detected below a depth of 30 feet.
Based on the analysis of soil samples collected upon the completion of excavation of soil
following UST removal, the aerial extent of any remaining hydrocarbons in soils in the
former UST pit area is expected to be small. The results of this investigation suggest a
very limited vertical extent also, restricted to less than 35 feet bgs.

GEORESEARCH PROCEDURES FOR COMPLETING SOIL BORINGS
The following outline describes the procedures adhered to by GeoResearch for
completion of soil borings.
i. Soil borings are advanced with hollow-stem, continuous flight auger. The
size of the auger's outside diameter is determined by the purpose of the
boring. For soil sample collection or well installation, usually 8 or 10-inch
outside diameter augers are used.
ii. The boring, if vertical, is advanced to a specified depth below ground
surface. If the boring is slanted from vertical, the augers are placed at the
specified angle to vertical and then advanced to a specified depth.
iii. During drilling, a continuous log of the sediments is made by a
geohydrologist in accordance with the Unified Soil Classification system.
iv. The auger lengths are steam-cleaned prior to each boring to prevent
intercontamination of borings. The rinsate from cleaning will be stored on
site in DOT-approved, 55-gallon drums.

e
GEORESEARCH PROCEDURES FOR SOIL SAMPLING
DURING DRILLING
The following outline describes the procedures utilized by GeoResearch for soil sampling
during drilling, using hollow-stem, continuous-flight augers.
I. Soil samples are collected using a 2.0 to 2.5-inch inside diameter, modified
California split-spoon sampler. The sampler is lined with two to three, 6-
inch long, 2.0 to 2.5-inch diameter brass rings for containment of the soil
samples.
ii. To avoid cross-contamination of samples, the sampler and rings are
washed prior to each use with non-phosphate detergent and double rinsed
with distilled water.
iii. At the prescribed sampling interval of 5 feet, the sampler is attached to the
drive rod and driven 18 inches into undisturbed soil below the lead auger
with a 140-pound hammer that is repeatedly dropped from a 30-inch height.
The number of drops is recorded during each 6-inch increment and used
as a qualitative determination of soil consistency and density.
iv. The lead, or deepest, brass ring is recovered from the sampler, sealed by
taping aluminum foil and plastic caps onto both ends, labeled, placed in a
Zip-Ioc bag, and stored on blue ice while awaiting delivery to the laboratory
for chemical analysis.
v. The sample is recorded onto a Chain-of-Custody form to ensure trackability
of the sample.
vi. The sampled interval is classified using the remaining rings and described
on a log of soil boring form, following the Unified Soil Classification System.
vii. Every 10th sample collected will be used as a duplicate sample to
determine analytical precision and accuracy. In addition, a field blank will
be collected from a newly opened bag of gravel pack material and analyzed
to test for cross contamination of soil samples.

e
GEORESEARCH PROCEDURES FOR SOIL SAMPLING USING A HAND AUGER
The following outline describes the procedures utilized by Geo,Research for soil sampling
utilizing a hand auger.
i. Soil borings are advanced to a specified depth using the hand auger.
ii. A clean drive sampler is lined with one or two (depending on the type
sampler) 1.5 to 2.0-inch diameter, stainless steel or brass tube(s). Samples
are obtained by driving the sampler into the soil with the drive hammer.
iii. The tubes are removed from the sampler. The ends of each or either tube
are covered with aluminum foil, covered with plastic caps, and taped with
duct tape.
iv. Each collected soil sample is labeled, recorded on a Chain-of-Custody
record and placed on ice while awaiting transport to a certified hazardous
waste laboratory.

DESCRIPTION OF LABORATORY ANALYTICAL METHODS

SUMMARIES OF LABORATORY ANALYTICAL METHODS:
SOIL SAMPLES
The following briefly describes laboratory analyses performed on soil samples in
accordance with the specified EPA or California Department of Health Services methods.
EPA Method 8020: Volatile Aromatic Orqanics .
Volatile aromatics are determined by purge and trap followed by gas
chromatography/photoionization detector (GC/PID). Normally only Benzene, Toluene,
Ethylbenzene and total Xylenes are analyzed with this method. A small amount of
sample (about 1 gram) is placed in a purge vessel and 5 ml water added. The sample
is purged for a specific time and the volatiles absorbed on a trap. After purging the trap
is heated and the volatiles swept into the GC. The analytes are separated using a
capillary column and detected using a photoionization detector.
Total Petroleum Hvdrocarbons - Gasoline
The volatile components of gasoline are determined by purge and trap followed by
gas chromatography/flame ionization detector (GC/FID). A small amount of sample
(about 1 gram) is placed in a purge vessel and 5 ml water added. The sample is purged
for a specific time and the volatiles absorbed on a trap. After purging the trap is heated
and the volatiles swept into the GC. The analytes are separated using a capillary column
and detected using an FID. The total petroleum hydrocarbon as gasoline (TPH-G) is
determined as the total amount of volatiles detected.
Total Petroleum Hvdrocarbons - Diesel
Total petroleum hydrocarbons as Diesel (TPH-D) is determined by extracting a soil
sample with pentane. The extract is analyzed by gas chromatography with a flame
ionization detector (GC/FID). The TPH-D is determined as the total amount of
compounds detected in the range where diesel elutes from the capillary column.

Dear Mr. Huey:
This letter is being provided at your request in order to update you on the disposition of
stockpiled soils from the above mentioned site. Of the estimated 400 cubic yards of soil
currently stockpiled on site, 250 cubic yards will be taken to the Arvin landfill and used
for cover material. This action has received approval from the Kern County
Environmental Health Department (KCEHD), (see attached letter).
Of the remaining 150 cubic yards of soil, some will be taken to the former Unocal station
located at 2700 Panama Lane and used to fill-in existing low spots created by the
removal of the canopy foundations. Any remaining soils left at the White Lane site will
be covered with plastic as a dust control measure.
If you have an~ questions, please feel free to call me at (209) 264-0444.

RE: Reguest for Appro I to Trans. ort and Dis ose of Soils from Former
(ûñ'óCãl Service Státion #7048, 2518 White ~ at the Arvin Landfill
Dear M r. Efada:
On behalf of Unocal Corporation, this letter has been prepared at your request in order
to provide you with the required information necessary for approving the transportation
and disposal of non-contaminated soils from the above mentioned site. The purpose of
this letter is to request your authorization to dispose of approximately 250 cubic yards of
soil at the Arvin Landfill. Attached is the following documentation:
1. Results of soil stockpile sampling that occurred during the underground tank
removal (Table 7 and Figure No. 2 from GeoResearch Project No.
9370007) ,
2. Letter from Ralph Huey of the Bakersfield Fire Department authorizing
disposal of soils (below action levels),
3. STLC Extraction test results, as required by Kern County Environmental
Health Department (KCEHD) for disposal at Arvin landfill.
BACKGROUND
There is approximately 400 cubic yards of soil which is currently stockpiled on this site.
These soils are from UST removal activities conducted during September 1992. They
were originally sampled on September 18, 1992. The attached Table 7 shows the highest
concentration of total petroleum hydrocarbons (TPH) as gas and diesel at 3.6 mg/kg and
27 mg/kg respectively at that time. All other constituents (BTEX and Oil & Grease) were
either non-detect (NO) or below action levels. During the week of July 19, 1993, I
discussed this matter with Ms. Dianna Wilson, KCEHD. She sent me the analytical
testing requirements for soil disposal at the Arvin Landfill. Based on the results of the
e
.
initial testing of the stockpile soils from Table 7, Ms. Wilson required that the soils be
retested by extraction method for TPH-G and TPH-D.
CURRENT
On Friday, July 30, 1993, GeoResearch conducted random sampling of the stockpiled
soils. This included 14 samples into 4 composites. These samples were submitted to
GEOTEST, a state certified laboratory located in Long Beach, California, and tested in
accordance with Title 22 WET Extraction/5030 for Total Petroleum Hydrocarbons as
Gasoline, and in accordance with Title 22 WET Extraction/3510 for Total Petroleum
Hydrocarbons as Diesel. All sample composites were ND with the exception of soil
composite WL-1,WL-2,WL-3,WL-4, which was 2.2 mg/L for gasoline (see attached lab
report). GeoResearch estimates that the soil composite from WL-1,WL-2,WL-3,WL-4,
represents approximately 150 cubic yards. We understand that the acceptance limits for
gasoline at the Arvin Landfill is 1 mg/L. As such, these soils will be segregated and will
not be disposed of at the Arvin Landfill. Only the soils that tested as ND will be disposed
of at Arvin, approximately 250 cubic yards.
I have tentatively scheduled to have these soils moved on Wednesday, August 4, 1993.
Your immediate attention to this matter would be greatly appreciated. Please call me at
(209) 264-0444 to discuss.

Based on these results this soil can be removed from this site and used or disposed of
in any manner consistent with current environmental regulations.
This department sees no reason to restrict the transportation of this soil, however we do
request information on the disposition of this material.

RE: Work Plan for Additional Subsurface Assessment, Unocal
Service Station No, 7048, 2518 White Lane, Bakersfield,
California, geoResearch Project No. 937000701.
Dear Mr. Huey:
GeoResearch is pleased to present this work plan for additional
subsurface assessment at the above-referenced site, This work plan
was prepared at the request of Mr. Ed Ralston of UnocalCorporate
Environmental Remediation and Technology, The purpose of this work
is to determine the vertical and lateral extent of petroleum
hydrocarbons beneath dispenser islands #1 and #3 (Figure 1) and to
confirm the adequate removal of petroleum hydrocarbons from the
former UST pit,
BACKGROUND
According to a Phase I site investigation (PHR, October 1992), in
1985 the two 6,OOO-gallon diesel USTs were manifolded together and
backflow valves and leak detectors were installed, The manifold
valve was reported to have stuck open and diesel fuel from one of
the USTs was pumped into the other and out the fill port: An
unknown quantity of fuel was lost. Subsequently, an investigation
was conducted by Consolidated Testing Laboratory of Bakersfield,
California. This subsequent investigation included drilling a
boring near the north ends of the easternmost 6,000-gallon diesel
. UST and the 10,OOO-gallon gasoline UST to 41 feet bgs (Figure 1),
Soil samples were collected and analyzed for benzene, toluene,
ethylbenzene, and total xylenes (BTEX), isopropylbenzene, and
ethylene dibromide (EDB). According to laboratory reports,
concentrations of BTEX and EDB were not identified below 10 foot
-bgs. The samples were apparently never analyzed for diesel
although the boring log indicated that petroleum odors were
detected from the surface to the bottom of the boring.

completed soil sampling as the station's UST I S and associated
product lines were removed. Soil with field evidence of
hydrocarbons was removed from the UST pit. Concentrations of up to
280 mg/kg total petroleum hydrocarbons as diesel (TPH-D) and 110
mg/kg total petroleum hydrocarbons as gasoline (TPH-G) accompanied
by low concentrations of toluene and total xylenes were identified
below the easternmost diesel UST at a depth of 22 feet bgs, This
soil was removed and a confirmation sample was collected, with the
excavator bucket at its maximum extension of 26 feet bgs, This
sample was found to contain only a low concentration of toluene
(O,007 mg/kg), Soil samples collected from the excavation's
southern sidewall at 18 bgs revealed that concentrations of TPH-D
as high as 33 mg/kg were still present,
Soil underlying each end of island #1 (south of building, Figure 1)
was observed to be hydrocarbon stained and contain strong petroleum
odors. A soil sample obtained six. feet below the west end of
island #1 was found to contain TPH-G at 630 mg/kg and a TPH-D at
250 mg/kg. Samples obtained six feet below the east end of island
#1 contained TPH-G and TPH-D of 9,700 and 830 mg/kg, respectively.
Soil was removed from the excavations to a depth of 11 feet and
soil samples were collected. According to laboratory reports, soil
collected at 11 feet bgs adjacent to each end of the island did not
contain TPH-G or TPH-D¡ however, the excavated soil contained very
strong hydrocarbon odors from the surface to 11 feet bgs.
Excavation beyond 11 feet bgs was not practical due to the close
proximity of the dispenser island and overhead canopy which would
have been affected by the loose and caving sands,
Soil beneath and adjaçent to the south end of dispenser island #3
(west of building, Figure 1) was stained dark brown to black to a
depth of approximately 6 feet bgs. Soil adjacent to the former
diesel dispenser at island #i was excavated to 11 feet bgs in an
attempt to determine the vertical extent of diesel in the soil. A
sample collected at 11 feet bgs was found to contain 13,000 mg/kg
TPH-D. Deeper excavation was not practical due to caving of loose
sands. Soil removed from beneath both dispenser islands was placed
back in to their respective excavations after the 11-foot bgs
samples were collected.
We propose drilling eight soil borings to delineate the vertical
and horizontal distribution of petroleum hydrocarbons in site
soils. Four of the borings would be used to delineate the vertical
extent of petroleum hydrocarbons by drilling to a depth of up to 50

feet bgs utilizing a truck-mounted drill rig equipped with hollow-
stem augers. Up to four hand auger borings will also be completed
beneath the canopy to depths of approximately 20 feet bgs for
lateral delineation of petroleum hydrocarbons (Figure 1).
The borings advanced using a hollow-stem auger methods will be
located in areas of known or potential petroleum hydrocarbon
contamination previously discussed. The first will be drilled near
the location of the former diesel USTs in order to verify if
significant concentrations of hydrocarbons still exist beneath the
former diesel UST, A second boring will be angle drilled beneath
the diesel dispenser formerly located on the south end of island
#3, The third and fourth hollow-stem auger borings will be angle
drilled beneath the gasoline dispensers at each end of island #1,
Soil samples will be collected at 5-foot intervals and submitted to
GEOTEST of Long Beach California, a California Environmental
Protection Agency (Cal-EPA) certified laboratory, Soil samples
will be screened' with a portable organic vapor analyzer (OVA) for
an indication of the presence of hydrocarbons and as criteria for
determining the depth to terminate each boring. In the event that
field evidence of gasoline persists beyond 50 feet bgs, the boring
will be deepened with continued sampling at 5-foot intervals, An
attempt will be made to collect a minimum of two consecutive
samples with no detectable concentrations. Selected soil samples
will be analyzed for TPH-G, TPH-D, and/or BTEX,
In addition, we have prepared a contingency plan for the completion
of additional soil borings, if necessary to establish the lateral
extent of identified soil contamination, The contingency plan also
considers the potential installation of vapor extraction wells if
soils with high concentrations of volatiles should be identified at
depths that would preclude excavation. The contingency plan is
described in the enclosed proposed scope of work.

RE: Work Plan for Additional Subsurface Assessment, Unocal
Service Station No. 7048, 2518 White Lane, Bakersfield,
California. GeoResearch Project No. 937000701.
Dear Mr. Huey:
GeoResearch is pleased to present this work plan for additional
subsurface assessment at the above-referenced site. This work plan
was prepared at the request of Mr. Ed Ralston of Unocal Corporate
Environmental Remediation and Technology. The purpose of this work
is to determine the vertical and lateral extent of petroleum
hydrocarbons beneath dispenser islands #1 and #3 (Figure 1) and to
confirm the adequate removal of petroleum hydrocarbons from the
former UST pit.
BACKGROUND
According to a Phase I site investigation (PHR, October 1992), in
1985 the two G,OOO-gallon diesel USTs were manifolded together and
backflow valves and leak detectors were installed. The manifold
valve was reported to have stuck open and diesel fuel from one of
the USTs was pumped into the other and out the fill port. An
unknown quantity of fuel was lost. Subsequently, an investigation
was conducted by Consolidated Testing Laboratory of Bakersfield,
California. This subsequent investigation included drilling a
boring near the north ends of the easternmost G,OOO-gallon diesel
UST and the 10,OOO-gallon gasoline UST to 41 feet bgs (Figure 1).
Soil samples were collected and analyzed for benzene, toluene,
ethylbenzene, and total xylenes (BTEX), isopropylbenzene, and
ethylene dibromide (EDB). According to laboratory reports,
concentrations of BTEX and EDB were not identified below 10 foot
bgs. The samples were apparently never analyzed for diesel
although the boring log indicated that petroleum odors were
detected from the surface to the bottom of the boring.

In September 1992, GeoResearch observed soil conditions and
completed soil sampling as the station's UST I S and associated
product lines were removed. Soil with field evidence of
hydrocarbons was removed from the UST pit. Concentrations of up to
280 mg/kg total petroleum hydrocarbons as diesel (TPH-D) and 110
mg/kg total petroleum hydrocarbons as gasoline (TPH-G) accompanied
by low concentrations of toluene and total xylenes were identified
below the easternmost diesel UST at a depth of 22 feet bgs. This
soil was removed and a confirmation sample was collected, with the
excavator bucket at its maximum extension of 26 feet bgs. This
sample was found to contain only a low concentration of toluene
(0.007 mg/kg). Soil samples collected from the excavation's
southern sidewall at 18 bgs revealed that concentrations of TPH-D
as high as 33 mg/kg were still present.
Soil underlying each end of island #1 (south of building, Figure 1)
was observed to be hydrocarbon stained and contain strong petroleum
odors. A soil sample obtained six feet below the west end of
island #1 was found to contain TPH-G at 630 mg/kg and a TPH-D at
250 mg/kg. Samples obtained six feet below the east end of island
#1 contained TPH-G and TPH-D of 9,700 and 830 mg/kg, respectively.
Soil was removed from the excavations to a depth of 11 feet and
soil samples were collected. According to laboratory reports, soil
collected at 11 feet bgs adjacent to each end of the island did not
contain TPH-G or TPH-D¡ however, the excavated soil contained very
strong hydrocarbon odors from the surface to 11 feet bgs.
Excavation beyond 11 feet bgs was not practical due to the close
proximity of the dispenser island and overhead canopy which would
have been affected by the loose and caving sands.
Soil beneath and adjacent to the south end of dispenser island #3
(west of building, Figure 1) was stained dark brown to black to a
depth of approximately 6 feet bgs. Soil adjacent to the former
diesel dispenser at island #3 was excavated to 11 feet bgs in an
attempt to determine the vertical extent of diesel in the soil. A
sample collected at 11 feet bgs was found to contain 13,000 mg/kg
TPH-D. Deeper excavation was not practical due to caving of loose
sands. Soil removed from beneath both dispenser islands was placed
back in to their respective excavations after the II-foot bgs
samples were collected.
We propose drilling eight soil borings to delineate the vertical
and horizontal distribution of petroleum hydrocarbons in site
soils. Four of the borings would be used to delineate the vertical
extent of petroleum hydrocarbons by drilling to a depth of up to 50

feet bgs utilizing a truck-mounted drill rig equipped with hollow-
stem augers. Up to four hand auger borings will also be completed
beneath the canopy to depths of approximately 20 feet bgs for
lateral delineation of petroleum hydrocarbons (Figure 1) .
The borings advanced using a hollow- stem auger methods will be
located in areas of known or potential petroleum hydrocarbon
contamination previously discussed. The first will be drilled near
the location of the former diesel USTs in order to verify if
significant concentrations of hydrocarbons still exist beneath the
former diesel UST. A second boring will be angle drilled beneath
the diesel dispenser formerly located on the south end of island
#3. The third and fourth hollow-stem auger borings will be angle
drilled beneath the gasoline dispensers at each end of island #1,
Soil samples will be collected at 5-foot intervals and submitted to
GEOTEST of Long Beach California, a California Environmental
Protection Agency (Cal-EPA) certified laboratory. Soil samples
will be screened with a portable organic vapor analyzer (OVA) for
an indication of the presence of hydrocarbons and as criteria for
determining the depth to terminate each boring. In the event that
field evidence of gasoline persists beyond 50 feet bgs, the boring
will be deepened with continued sampling at 5-foot intervals. An
attempt will be made to collect a minimum of two consecutive
samples with no detectable concentrations. Selected soil samples
will be analyzed for TPH-G, TPH-D, and/or BTEX.
In addition, we have prepared a contingency plan for the completion
of additional soil borings, if necessary to establish the lateral
extent of identified soil contamination. The contingency plan also
considers the potential installation of vapor extraction wells if
soils with high concentrations of volatiles should be identified at
depths that would preclude excavation. The contingency plan is
described in the enclosed proposed scope of work.

Dear Mr, Huey:
This letter is written in response to your letter dated March 4, 1993
(received March 9, 1993) regarding the closure report for the above-
mentioned station. First of all, thank you for your time in reviewing
the report and fire department files and providing a response in this
matter, I appreciate the magnitude of the task you face in coming up
to speed on all of the sites which Inspector Dunwoody had pending at
the time of his departure,
Unocal readily acknowledges that the full extent of petroleum
hydrocarbons in site soils have not been adequately defined and that
further investigation is required, Please note that all sources of
contamination were removed in association with the removal of the
underground storage tanks and associated fuel lines. The site is
fenced and the depth to groundwater is reported to be 185 feet below
ground sùrface (bgs) in this area. Unocal therefore does not consider
this site to pose an immediate threat to human health or to
groundwater,
In accordance with your request, Unocal has requested from our
consultant a workplan for further site assessment. The work plan has
been received and is presently under review, In consideration of the
revisions to the workplan and consultation with our Real Estate
Division regarding the status of this property, Unocal respectfully
requests an extension of the due date for the work plan. We anticipate
that the workplan will be submitted to you by May 31, 1993.
Regarding the closure report, please recognize that our consultant was
directed to provide a report containing all pertinent data and a
factual accounting of findings. It is Unocal policy in matters such as
these that no recommendations for further site investigation or
remediation be made prior to receiving comment from the appropriate
regulatory authority,
£' '. ~"

Thank you for your attention to this matter. If you have any questions
or comments in this matter please contact me at (510) 277-2311,

RE: Closure Report for Unocal Station 7048, 2518 White Lane
Dear Mr. Ralston:
I have completed the review of the tank closure report for the Unocal Service Station No.
7048, located at 2518 White Lane, Bakersfield, California. I find this report, submitted
by Georesearch to be deficient. The report does not contain specific recommendations,
however implies that leaving the existing contamination in place is acceptable. You state
that further investigation was not practical due to loose and caving sand but did not
consider any other sampling method. It is clearly not acceptable to allow contamination
levels of between 250 mgjkg and 13,000 mgjkg in place without knowing the full extent
of the contamination plume. This office has determined that the full extent of the
contamination plum has not been adequately defined.
This office requires (in accordance with Chapter 6.7 of the California Health and Safety
Code and Chapter 16, Title 23 of the California Code of Regulations) that further
assessment be done to define the vertical and horizontal extent of the contamination
plume.
Please submit a work plan for further assessment to this office, within 30 days from
receipt of this letter. The work plan should follow the guidelines found in Appendix A -
Reports, Tri-Regional Board Staff Recommendations for Preliminary Evaluation and
InvesÚgation of Underground Tank Sites; January 22, 1991. Submit a time line for
completion of this work and note that work shall not begin until the work plan is
approved by this office.
Additionally, be advised that oversight cost for this project will be billed to you at the rate
of $47.50 per hour.

Subject: Testhole at Union Service Station, 2518 White"lane, Bakersfield
Dear Bob, . -.'
At your request, we have drilled one (1) forty (40) foot testhole at the
subject site, Our sampling and testing procedures were conducted in accordance
with the California Underground Storage Tank regulations issued by the California
State Water Resources Control Board in August 1985 and Kern County Health
Department.
,
Our testhole was drilled on 12-5-85 at the location determinßd by the Kern
County Health Department. Undisturbed (intact) soil samples were collected
at five (5) foot intervals to a depth of forty (40) feet, "
A.-Clrillrig, using a six and one half (6~) inch hollow stem auger, was used
to bore the testhole. All auger flights were steam cleaned prior to drilling.
Undisturbed soil samples were collected using a two and three-eighths (2
3/8) inch inside diameter split spoon sampler and a one and three-eighths
(1 3/8) inch inside diameter split barrel sampler, Samplers were steam
cleaned before and after sampling each time. I
Laboratory tests that were conducted on the samples collected at the request
of the Kern County Health Department were for the constituents listed below:
Benzene
Toluene
Ethulbenzene
Isoppopylbenzene
P-xylene
O-xylene
r~- xyl ene
EDB
Persons present at various times during drilling and sampling operations
were Joe Canas (Kern County Health Department) and Chuck Collins. (Fhemco)

Soils encountered in our testhole generally consisted of silty sand; dark
yellowish brown; moist; fine-coarse grain size; with ~ very slight petroleum
odor at the upper three and one-half (3~) feet and classified as S~1 (SP)
in ac~ordance with the Unified Soil Classification System. Soils from three
and one-half (3~) feet to forty (40) feet were sand; dark olive brown-light
yellowish brown; damp; medium-coarse grain size; petroleum odor present
(SP) see boring log for more detailed information;
Our test results indicated that the detected level was below the maximum
allowable limit of one hundred (100) parts per million, See attached results
.for further i nforma ti on,
Since the odor of petroleum was present in our samples and noted during
drilling operations, additional tests were conducted to confirm our original
test results,
Because of the pervious type of soils that exist at the site, it is possible
that the petroleum would not concentrate but would disipate ~hroughout the
soil leaving an odor in a large area, ;'
I
During drilling and sampling operations, groundwater was not encountered
in our testho1e. After sampling was completed, the testho1e was abandoned
añd filled with bentonite grout using the tremie method.
Attached are the laboratory test results, Unified Soil Classification System
Chart, boring log legend, boring log and a location map showing the testhole
boring on the subject site.
If you should have any questions regarding our report or if we can be of
further service, please contact our office.

MINOR PIPE MODIFICATIONS
AND BLEND VALVE INSTALLATION
Dear Ms, Boyce:
,
On behalf of Unocal 76 we are submitting these plans and fee of
$1800,00 ($100,00 per facility) for minor piping.'~odifications
at each Unocal leased service station within your jurisdiction:
5.-. S . #1367 - Bakersfield S.S, #7048 ~' Bakersfield
#3507 - Bakersfield #7225 - Bakersfield
#3609 - Bakersfield #4669 - Delano
#3655 - Bakersfield #5334 - Greenfield
#4888 Bakersfield #4734 Lebec
#5488 - Bakersfield #5895 - Lost Hills
#5573 - Bakersfield #5716 - Oildale
#6089 - Bakersfield #3596 - Ridgecrest
#6106 - Bakersfield #2989 - Taft
These modi£ications will be minimal, involving about 0-10% of
the total existing piping system which is currently monitored
with Red Jacket leak detectors. Providing these changes and
installing a U,L. listed "Blend Valve" within selected
dispensers will allow the service station dealer to provide an
additional gasoline product to the customer,
We are requesting at this time a variance from secondary
containment requirements on these minor modifications, Please
see our formal letter, attached,
Please review the~e plans and advise this office of your
approval. The instalJation contractor has been given
responsibility for obtaining and meeting all other local permits
and requirements.

Ms. Ann Boyce
As per your conversation with Paul Yamamoto of our office, the
Contractor will be installing a pan under the dispensers.
As our client has developed a very rigid schedule, any assistance you
cart provide us in expediting your processing would be greatly
appreciated. We will be available to assist you with any and all
questions you might have at (415) 461-8890. Plêase advise us when
permits are ready to be picked up.
No As-Builts should be required as all construction will be as
designed.
Again, your assistance is greatly appreciated.
Very truly yours,

RE: REQUEST FOR VARIANCES FROM SECONDARY
CONTAINMENT REQUIREMENTS ON SHORT PIPING ADDITIONS
Dear Ms, Boyce:
Unocal 76 has embQrked upon a region wide program to provide an
additional gasoline product to their consumers at all service
stations, Rather than install another underground tank, Unocal
has opted to perform minor modifications to existin~ product and
vapor recovery piping at the dispenser islands and,ln some cases
only underneath the dispensers themselves to provÏde this third
product, Additional product piping of approximately 0-10 feet
in length or O-lU~ ~f the total piping may be required,
On behalf of Unocal ue request your consideration for a variance
from secondary containment requirements on minor new additions
1::0 produc·tpipin<j ror rj¡(:, follm1Îng t"ëdsons:
1. FrOlI1 1974-1076, Unoca] v01\1l1tarily replaced all
galvaniz2d product piping witl) corrosion resistant
fillerglass piping at all servica stations as part of
tlh.~ir ú\JJ1 Phase I Leak Prevention Program, .
2, Unocal has es-tablished as part of their Phase II Leak
Prevent10~ ~rogram an ongoing tank replacement project
t:hrougrl \J¡,j (:h all single \.¡all tanks and piping will be
replaced \lÍth double wall tanks and. secondarily
contained piping at all service stations, This
program has been in effect for several years and it is
Unocal's intent to eventually eliminate all single
wall steel tanks and single wall piping from their
system of service stations,
3, Red Jacket Line Leak Detectors are installed and are
operating at all service stations.

4. All stations with single wall fueling facilities are being
precision tested for tightness on an annual basis as
required by state and/or local law.
5. station dealers are required by law as well as their lease
agreements to perform daily inventory 'reconciliation on
their motor vehicle fuels and to advise both government
agencies and company representatives when specified
discrepancies occur.
In addition, there are real limitations on funds, time and
availability of manpower for this project. Unocal's resources are
finite. Secondary containment requirements for a project of this
magnitude may make it difficult or impossible to completé with
available resources. ¡
,
It is also felt that the dollars and effort spent on éreating and
monitoring a hybrid double/single wall fueling system might be more
effectively and efficiently spent within the context of Unocal's
ongoing tank replacement program through which "complete" tank and
piping systems are replaced at all service stations on a prioritized
basis.
Your consideration of the above is greatly appreciated. Should you
have any questions or response regarding this matter, please do not
hesitate to contact our office at (415) 461-8890,
Very truly yours,

Per CIL\)- telephone cClnve1-saticln on this date, thf"
ipformation is being forwarded to you with reg~

Dear Mr. Casagrande:

1. Diesel product was in the tank and the
tank was converted to unleaded as per
Red Jacket specifications. An inline check
valve was installed between the turbines
and the proudct lines where you tie into
the other tank and this stops the product
from back flowing into the tank,
2. We will have a test well drilled for soil
samples at 10' - 20' - 30' - 40' between
the two (2) tanks and find out how deep and
to what extent the spill has gone.
We have receivèd approval from Mr. Frank Pinnell, UNOCAL,
to proceed with the installation of the overspill containers
on all three (3) tanks. This project will take place this
week. Because we understand what caused the problem and
the fact that we are taking care of the problem and with
your approval the station has continued to operate, We
will inform ~r. Joe Canus of the status of this project,
