LIMITED PHASE II ENVIRONMENTAL SITE ASSESSMENT
PROPOSED BIG O TIRE STORE
MING AVENUE AND HUGHES LANE
BAKERSFIELD, CALIFORNIA
1.0 INTRODUCTION
This report presents the results of our Limited Phase II Environmental Site Assessment (ESA) for the site
identified as the proposed Big O Tire Store located at the northwest corner of Ming Avenue and Hughes
Lane in Bakersfield, California. Mr. Anthony Olivieri of Olivieri Commercial Group, on behalf of Big O
Tire Stores, provided written approval of Krazan & Associates, Inc. (Krazan) Proposal No. P98-277
dated July 30, 1998 to proceed with the Limited Phase II ESA.
2.0 BACKGROUND
Krazan conducted a Phase I ESA for the subject site (report dated July 16, 1998), under the authorization
of Big O Tire Stores. According to information reported in the Phase I ESA report, the subject site was
developed in 1968 as a gasoline service station. Two 10,000-gallon gasoline underground storage tanks
(USTs) were installed on the subject site in 1975. According to records on file with the City of
Bakersfield Fire Department, Environmental Services. Department (CBESD), one 550-gallon waste oil
UST (installed in 1968) and the two 10,000-gallon gasoline UST's (installed in 1975) were removed
from the subject site in 1994. The former service station facilities and UST locations are shown on
Figure 1. GeoResearch was contracted by Unocal Corporation (Unocal) to conduct the UST removal,
additional investigations, and limited soil remediation at the subject site.

Based on the results of the additional investigations and limited remediation conducted by GeoResearch
at the subject site, the CBESD granted closure for the subject site in a letter dated October 5, 1994.
However, no information regarding the fate of the late 1960s gasoline USTs (assumed to have been
located on-site)} was presented by GeoResearch. The conclusions and recommendations of the Krazan
Phase I ESA included the following:
3.0
Due to the lack of records for the installation and removal of gasoline USTs
prior to 1975, it is necessary to confirm whether or not any prior UST
generations exist beneath the subject site. A geophysical survey consisting
of a magnetometer and a ground-penetrating radar reconnaissance survey
of the subject site should be conducted to confirm that no other USTs exist
beneath the subject site.
Based on records reviewed at the CBESD, no sign~icant contamination
exists beneath the subject site. Full closure for the demolition of the Unocal
service station was issued by the CBESD on October 5, 1994.
PURPOSE OF THE AUGUST 1998 LIMITED PHASE I1 ESA
The purpose of the August 1998 assessment was to determine if the 1960s gasoline USTs remained on
the subject site and if releases of petroleum hydrocarbon constituents (PHCs) are present in soils in the
vicinity of the 1960s USTs.
4.0 SITE LOCATION AND DESCRIPTION
The subject site is located on the northwest corner of Ming Avenue and Hughes Lane in Bakersfield,
Kern County, California. According to the U.S. Geological Survey, 7.5 minute Gosford, California
topographic map, the subject property is located in the southwest quarter of Section 1, in Township 30
South, Range 27 East, Mount Diablo Baseline and Meridian. The subject site is currently undeveloped
vacant land.

The scope of Krazan's August 1998 Limited Phase II ESA included the following:
On July 24, 1998, Krazan contracted with Maverick Environmental Services
(Maverick) of Simi Valley, California to conduct a geophysical survey at the subject
site. During the geophysical survey, Maverick identified the former (1994) UST
excavation and an anomalous excavation (geophysical anomaly) at the subject site.
The locations of the excavations identified by Maverick are shown on Figure 2.
Based on the size and location of the anomalous excavation, it is anticipated that it
may be a former location of the late 1960s USTs previously associated with the
subject site. No existing USTs were identified by the July 24, 1998 geophysical
survey at the subject site.
Krazan prepared a Limited Phase II Environmental Site Assessment Workplan, 2502
Ming Avenue, Bakersfield, California, dated August 12, 1998, which was submitted
to the CBESD for review and approval. In a letter dated August 13, 1998, Mr. Ralph
Huey of the CBESD acknowledged the receipt of the work plan and indicated that
Krazan may conduct the proposed work. Copies of the August 12, 1998 work plan
and the August 13, 1998 CBESD letter are included in Appendix A.
On August 18, 1998, two 20-foot soil borings (B-1 and B-2) were advanced within
the limits of the geophysical anomaly. The locations of the soil borings are shown
on Figure 2.
Soil samples collected at 10 feet and 20 feet below ground surface (bgs) from these
borings were submitted for chemical analysis.

The selected soil samples were analyzed for benzene, toluene, ethylbenzene, and
xylenes (BTEX); methyl tertiary butyl ether (MTBE) by EPA Method 8020; and for
total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015M.
· Because no hydrocarbon odors, discolored soil or positive PID readings were noted
during field operations, the soil borings were backfitled with drill cuttings.
· Specific field methods employed are presented in Appendix B.

DISCUSSION OF FINDINGS
Project No. 024-98056
Page No. 5
During the July 24, 1998 geophysical survey conducted at the subject site, a geophysical anomaly was
identified in the northwestern portion of the subject site. Based on the size and location of the
geophysical anomaly, it is anticipated that it may be a former location of the late 1960s USTs previously
associated with the subject site. No existing USTs were identified by the July 24, 1998 geophysical
survey at the subject site.
Based on the soil sample analytical results of the August 1998 Limited Phase II ESA, no detectable
concentrations of BTEX, MTBE, or TPH-G were present in the samples. Additionally, no soil
discoloration, hydrocar, bon odors, or positive PID readings were noted in any of the soil samples
collected. ·
8.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the findings of the Limited Phase II ESA, there are no indications that PHCs have impacted
soils in the vicinity of the geophysical anomaly which is located within the northwestern portion of the
subject site. It is Krazan's opinion that further assessment of the issuer related to the 1960s UST is not
warranted.
Krazan recommends that a copy of this report be submitted to the following:

accurate only to the degree implied by the methods used to locate them. The conclusions presented in
this report are based upon site conditions as they existed at the time of our field investigation.
Additionally, it is assumed that the soil borings advanced on the subject site are representative of
subsurface conditions everywhere on the site; that is, subsurface conditions on the subject site do not
vary significantly from those disclosed by the soil borings.
Chemical testing was conducted by laboratories certified by the State of California Department of Health
Services. The results of the chemical testing are accurate only to the degree of the care of ensuring the
testing accuracy and the representative nature of the soils obtained.
The findings presented herewith are based upon professional interpretation using state-of-the art methods
and equipment and a degree of conservatism deemed proper as of this report date. It is not warranted
that such data cannot be superseded by future geotechnical, environmental, or technical developments.
This investigation and report were authorized by and prepared for the exclusive use of our client.

Limited Phase II Environmental Site Assessment Workplan
2502 Ming Avenue
Bakersfield, California
Dear Mr. Wines:
On behalf of Big "O" Tire Company, Krazan & Associates, Inc. (Krazan) is requesting that the City of
Bakersfield Fire Department, Environmental Services Department (CBESD) approve of this workplan
for a Limited Phase II Environmental Site Assessment (ESA). Information related to the subject project
is summarized below.
Krazan conducted a Phase I ESA (report dated July 16, 1998) for the subject site in July 1988.
According to information noted during Krazan's Phase ! ESA, the subject site was developed in 1968 as
a gasoline service station. The only records of underground storage tanks (USTs) initially associated
with the subject site was a letter reference tO a 550-gal10n waste oil UST. It is anticipated that a gasoline
UST system was associated with the subject site during the late 1960s; however, the location of these
features and whether associated subsurface structures still exist on the subject site was not known.
According to records on file with the CBESD, one 550-gallon waste-oil UST (installed in 1968) and two
10,000-gallon gasoline USTs were removed from the subject site in 1994. The approximate locations of

the former USTs and associated service station are shown on Figure 1. Regulatory records indicated that
the two 10,000-gallon USTs removed in 1994 were installed in 1975. GeoResearch of Fresno California
was contracted by Unocal Corporation to document the removal of the two 10,000-gallon gasoline USTs,
one 520-gallon waste oil UST (it is anticipated that this UST corresponds to the previously mentioned
waste oil UST), three dispenser islands, two service bays with hydraulic lifts, and a septic system.
According to a Tank Closure Report prepared bY GeoResearch, dated July 11, 1994, "all observed and
monitored soil with field indication of petroleum hydrocarbons was excavated." Stockpiled soil from the
waste oil UST excavation was disposed of off site. Analysis of soil collected associated with stockpiled
soil from the dispenser islands detected low concentrations of petroleum hydrocarbon constituents were
present. These soils were aerated on-site. Analysis of soil samples collected from adjacent to the
hydraulic lift locations did not detect concentrations of total recoverable petroleum hydrocarbons.
Additionally, according to a Subsurface Site Investigation report prepared by GeoResearch, dated June 7,
1993, "information pertaining to the removal of the old USTs or the installation of the new USTs is
apparently not available".
Based on the absence of information regarding the fate of the late 1960s gasoline USTs (assumed to have
been located on-site), it is possible that the late 1960s USTs remained at the subject site. Based on the
unknown status of the late 1960s USTs, Krazan recommended that additional investigation be conducted.
On July 24, 1998, Krazan contracted with Maverick Environmental Services (Maverick) of Simi Valley,
California to conduct a geophysical survey at the subject site. During the geophysical survey, Maverick
identified the former (1994) UST excavation and an anamolous excavation at the subject site. The
locations of the excavations identified by Maverick are shown on Figure 2. Based on the size and
location of the anomalous excavation, it is anticipated that it may be a former location of the late 1960s
USTs previously associated with the subject site. No existing USTs were identified by the July 24, 1998
geophysical survey at the subject site.
Based 'on the fact that an anamolous excavation is currently located on the subject site, Krazan
recommended that a Limited Phase II ESA' be conducted for property transaction purposes. Information'
regarding the Limited Phase II ESA is listed below.

The property is owned by Unocal Corporation, located at 2000 Crow Canyon Place, Suite 400,
San Ramon, California 94583. The contact person is Mr. Bob Links of Unocal Corporation. Mr.
Links' telephone number is (602) 200-4561.
The project manager for this investigation will be Mr. Arthur H. Morrill, RG No. 5383.
The address of the site is 2502 Ming Avenue, Bakersfield, California. The Assessor's Parcel
Number is 148-230-40. The site is located in the southwest quarter of Section 1, Township 30
South, Range 27 East, Mount Diablo Baseline and Meridian.
· The site is. currently undeveloped and is unpaved.
According to information provided by the California Water Service, the estimated depth to
groundwater is approximately 188 feet below ground surface (bgs). The proposed depth of the
soil borings is 20 feet bgs. It is not the intention of this project to advance the soil borings into
saturated subsurface materials after penetrating contaminated soil. Sample depths are
summarized below.
Purpose of Assessment
The purpose of this assessment is to determine if PHCs associated with the former 1960s gasoline USTs
(anamolous excavation) are present in soils beneath the subject site. This assessment is not being
conducted to characterize and define the extent of impact of PHCs associated with the former USTs. It is
possible that additional soil borings and sample analyses will be required to fully assess the extent of
PHCs in the soil. In addition, findings from this investigation, or subsequent investigations, may indicate
the need for a groundwater assessment including the installation and sampling of groundwater
monitoring wells.

I~azan understands that no drilling permits will be required by the CBESD.
Before the commencement of drilling activities, Underground Services Alert (USA) would
be contacted to locate public underground utilities associated with USA subscribers.
Two soil borings will be advanced to approximately 20 feet bgs within the limits of the
anamolous excavation. The proposed soil boring locations are shown on Figure 2. The
soil borings will be drilled with a truck-mounted drill rig.
Soil samples will be obtained for logging purposes in the borings at five foot intervals,
beginning at five feet bgs. Soils would be logged in accordance with the Unified Soil
Classification System.
Sampling will be conducted by means of a split-spoon sampler containing three 6-inch
long by 2-inch diameter brass sleeves.
Two soil samples from each soil boring will be submitted for analysis of PHCs.
Soil samples obtained from the borings will be analyzed for benzene, toluene,
ethylbenzene, xylenes (BTEX) and methyl tertiary butyl ether (MTBE) by EPA Method
8020, total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015M.
Documentation related to precision and accuracy of analytical methodology will be
provided.
During the boring process, soil samples will be subjectively analyzed for odor and
discoloration. Additionally, the soil would be field screened with a portable
photoionization detector (PID). The PID reading would be recorded on the soil boring
log. The PID is a direct reading real-time analyzer that can detect most of the volatile
hydrocarbon constituents present in the vapor phase of petroleum-affected soils.
If no positive PID readings are noted during the drilling process, the boreholes will be
backfilled with drill cuttings.
In the event positive PID readings, petroleum hydrocarbon odors, or apparent petroleum
discoloration are observed during drilling, the drill cuttings (soil) will be temporarily
contained in DOT-approved steel 55-gallon drums. The borings would then be backfilled
with bentonite chips or sand/cement slugry.
Field work would be conducted by individuals meeting the Occupational Safety and
Health Administration requirements for hazardous waste work including 40-hour health
and safety tr~aining and medical monitoring. The work would be completed under
standards set forth by industry and deemed acceptable by various regulatory agencies.
Hard hats, protective eyewear, steel-toe boots, protective clothing, and respiratory devices
will be worn by field personnel when deemed appropriate 'by the field engineer or
geologist present.

Project Schedule
The drilling is scheduled to be conducted during the week of August 24, 1998', pending approval of this
workplan by the CBESD. It is anticipated that the field work will be completed in one day depending on
subsurface conditions encountered. Analysis of soil samples will be completed in approximately ten
working days following submittal to the laboratory. A report will be completed and submitted to Big
"O" Tire Company and the CBESD in approximately ten working days following receipt of the
analytical results from the laboratory.
Limitations
This workplan was prepared in accordance with generally accepted stmxdards of environmental practice
in Kern County at this time. The sampling and testing will be conducted solely for the purpose of
evaluating environmental conditions of the soil with respect to the presence of petroleum constituents at
the depths and locations sampled. No soil engineering or geotechnical implications are stated or should
be implied. Evaluation of site conditions for the purpose of sampling and testing will be made from a
limited number of observation and sampling points. Subsurface conditions may vary beyond the data
points available and it is not possible to account for these variations, despite exhaustive additional
testing.

RE:
Your Memo of August 12, 1998 to Howard Wines, Concerning a
Limited Phase II Site Assessment Work Plan.
Dear Mr. Berg:
Thank you for submitting the work plan for the limited Phase II
Environmental Site Assessment to be performed at 2502 Ming Avenue,
Bakersfield. This site assessment is being accomplished as part of an overall
property evaluation, as we understand it, at the request of Big "O" Tire
Company. This site assessment therefore, is not the result of a regulatory action.
This office does appreciate a copy of the work plan for information
purposes, however, we are not currently overseeing this project. This office
would oversee environmental projects within the city, if the investigation or clean
up were conducted as part of a regulatory action. Since this office is not
overseeing the project, it would not be appropriate to approve the work plan. We
must therefore respectfully decline your request to approve the work plan for
project number 02498058. This in no way limits your ability to complete the
work described in your work plan, or any other investigatory work associated
with this site.
If in your investigation, you do discover contamination, then, there is a
requirement to notify this office. At that point, a regulatory action could be
initiated which would then involve this office. Thank you again for submitting
your work plan.
Sincerely,
REH/dln

METHODOLOGIES
Soil borings were advanced by a truck-mounted drill rig utilizing hollow-stem
auger. Drilling fluids were not used while advancing the borings.
Soil boring samples were obtained for logging purposes at five foot intervals,
beginning at 5 feet bgs. Soils were logged in accordance with the Unified Soil
Classification System.
Sampling was conducted by means of a split-spoon sampler containing three 2-
inch diameter brass sleeves.
During the drilling process, soil samples were subjectively analyzed for odor and
discoloration. Additionally, soils were field screened with a portable
photoionization detector (PID). The PID readings were recorded on soil boring
logs. The PID is a direct reading real-time analyzer capable of detecting most of
the volatile hydrocarbon constituents present in the vapor phase of petroleum-
affected soils.
Following sample retrieval from the soil borings, Teflon® film was placed over
both ends of each sleeve. Each sleeve was sealed with tight fitting plastic caps
that were secured with adhesiveless tape.
Samples were labeled with the project number, the sampler's initials, the boring
number, and the time and depth at which the sample was obtained.
Following sample labeling, each sample was placed into an ice chest and
maintained at a temperature of approximately 4° Celsius with synthetic ice, to
limit the volatilization of any PHCs present.
Equipment used for the advancing of soil borings and the sampling of soils was
decontaminated (steam-cleaned, TSP, lab-grade detergents, etc.) before arriving
on-site, between each boring and/or smnpling, and before leaving the site each
day, or as necessary to minimize the chances of cross-contamination.
Field work was conducted by individuals meeting the Occupational Safety and
Health Administration (OSHA) requirements for hazardous waste work
including 40-hour health and safety training and medical monitoring. The work
was completed under standards set forth by the industry and deemed acceptable
by various regulatory agencies. Hard hats, protective eye wear, steel-toe boots,
protective clothing, and respiratory devices were worn by field personnel when
deemed appropriate by the field engineer or geologist present.

Please Note:
The LCS (Laboratory Check Sample) is a control sample of known, interferent free matrix that is fortified with representative analytes and
analyzed using the same reagents, preparation and analytical methods employed for the samples. The LCS % recovery is used for validation
of sample batch results. Due to matrix effects, the QC limits and recoveries for MS/MSD's are advisory only and are not used to accept or
reject batch results.
