August 31, 2021 Mr. Malcolm Moore Bakersfield Fire Department Prevention Services Division 2101 H Street, Floor 2 Bakersfield, California 93301 TANK CLOSURE SOIL SAMPLING REPORT FOR THE KERN HIGH SCHOOL DISTRICT TRANSPORTATION DEPARTMENT 3701 EAST BELLE TERRACE, BAKERSFIELD, CALIFORNIA (BFDPSD FACILITY NO. 15-021-003244 AND PERMIT TO ABANDON 21-10000359) Dear Mr. Moore:
The Kern High School District (KHSD) Transportation Department contracted with Falcon Services &
Construction, LLC (Falcon) to abandon a 1,000-gallon underground waste oil storage tank (UST) in place
due to the proximity of the UST to the service building at the site. The site is identified as Bakersfield Fire
Department Prevention Services Division (BFDPSD) Facility No. 15-021-003244 and the tank
abandonment was performed under the BFDPSD Permit to Abandon (PTA) 21-10000359
(see Attachment 1 for the BFDPSD PTA 21-10000359). Mark R. Magargee, PG, CHg (MRM) was
contracted by Falcon to conduct soil sampling and preparation of this Tank Closure Soil Sampling Report.
SITE DESCRIPTION
The site is located at 3701 East Belle Terrace, Bakersfield, Kern County, California (see Figure 1 - Site
Location Map). The site is located within the southwest quarter of Section 3, Township 30 South (T30S),
Range 28 East (R28E), Mount Diablo Base and Meridian (MDBM). The site elevation is approximately
355 feet above mean sea level (MSL). The topography at the site slopes gently to the south. The site is
located on the south side of Belle Terrace, approximately 2,000 feet to the east of Mount Vernon Avenue
and a quarter mile to the south of State Route 58 (see Figure 2 - Site Vicinity Aerial). The site is identified
as Kern County Assessor’s Parcel Number (APN) 173-200-07-00-0 (see Figure 3 – Assessor’s Parcel
Map). The site is the vehicle service facility for the KHSD Transportation Department. The facilities
include the service building, fueling facilities, and the subject 1,000-gallon waste oil UST, which as
abandoned in place due to the proximity of the UST to the service building at the site (see Figure 4 - Plot
Plan).

TANK CLOSURE SOIL SAMPLING
On August 17, 2021, the 1,000-gallon waste oil UST was abandoned in place. MRM was contracted to
provide a California Professional Geologist (PG) to collect soil samples at the direction of
Mr. Malcolm Moore with the BFDPSD from locations adjacent to the western side of the UST.
Soil samples TK-1-2 and TK-1-6 were collected from two and six feet beneath the depth of the invert of
the waste oil UST (see Figure 4 for the sample locations and Attachment 2 for a Photographic Log).
All sampling equipment was washed with a non-phosphate cleanser, pre-rinsed with tap water, and finally
rinsed with deionized water prior to sampling. The soil samples were collected from the backhoe bucket
and were stored in 1 1/2-inch-diameter stainless steel tubes, sealed with Teflon™ liners and end caps,
labeled, placed in an ice chest at a temperature of less than 4°C, and transported to a California
State-certified laboratory for analysis. Sample identification and chain-of-custody procedures were
followed for the samples to ensure sample integrity and to document sample possession from the time of
collection to the ultimate destination. The sample labels identified the job number, sampler, date and time
of collection, and a sample number unique to each sample. The soil samples were analyzed at
BC Laboratories, Inc. (BC Labs) for Total Petroleum Hydrocarbons (TPH) as oil using US Environmental
Protection Agency (EPA) Method 8015M; a full list of volatile organic compounds (VOCs) using
EPA Method 8260C, and the California Code of Regulations Title 22 metals using EPA Method 6010B.
TPH as oil and the full list of VOCs were not detected above either the minimum reporting level (MRL) or
the method detection limit (MDL) in the soil samples. Five of the 17 CCR Title 22 metals were not
detected above either the MRL or MDL. Arsenic, barium, chromium, cobalt, copper, lead, nickel,
vanadium, and zinc were detected at maximum concentrations of 9.1, 69, 19, 5.4, 7.1, 4.6, 9.6, 23, and
33 mg/kg, respectively, and beryllium, cadmium, mercury, and molybdenum had estimated J Flag values
of 0.37J, 0.30J, 0.019J, and 0.099J mg/kg, respectively, which are estimated values that are less than the
MRL but in excess of the MDL. All of the metals detected were less than 1/10 of their respective
CCR Title 22 Total Threshold Limit Concentrations (TTLCs) and consistent with the concentrations of
these metals in the near surface soils in the Bakersfield area (see Table 1 - Summary of Soil Sample
Analytical Results and Attachment 3 for the Laboratory Report).
KHSD Transportation 3701 East Belle Terrace Bakersfield, California August 31, 2021 - Page 3
CONCLUSIONS AND RECOMMENDATIONS
Based upon the laboratory results of the soil samples, TPH as oil and the full list of VOCs were not
detected and the CCR Title 22 metals which were detected, were detected at concentrations less than
1/10 of their respective CCR Title 22 TTLCs and consistent with the concentrations of these metals in the
near surface soils in the Bakersfield area. Therefore, MRM recommends that the BFDPSD issue a
No Further Action (NFA) determination in association with the in place abandonment of the 1,000-gallon
waste oil UST at the site.
This report has been prepared for the exclusive use of Falcon Service & Construction, LLC as it pertains
to the soil sampling conducted in association with the in place abandonment of the 1,000-gallon waste oil
UST at the KHSD Transportation Department, which is located at 3701 East Belle Terrace, Bakersfield,
Kern County, California. The services performed by MRM were conducted in a manner consistent with
the level of care and skill ordinarily exercised by members of its profession currently practicing under
similar conditions in the State of California. No other warranty is expressed or implied.
MRM trusts that you will find this Tank Closure Soil Sampling Report to your satisfaction. If you have
any questions or require additional information, please contact Mr. Mark R. Magargee, PG, CHg, at
