EXECUTIVE SUMMARY
This Removal Action Workplan (RAW) has been prepared by ENSR Corporation (ENSR) for the
Rosedale Highway Property (referred to in this document as the "project site" or "site"), located
at 2800 Standard Street and 3650 through 3880 Rosedale Highway in Bakersfield, California, to
present remedial actions and work tasks to be completed at the site. The site was formerly
occupied by oil production and automobile maintenance facilities. The RAW presents scopes of
work to be completed prior to site redevelopment, cleanup objectives for soil and a schedule for
implementation. This work will be completed to allow redevelopment of the site which
contemplates that the site will be covered by buildings, including a warehouse structure,
landscaped areas and a gasoline service station. The Site Vicinity Map is presented as Figure
1 and the Site Plan as Figure 2.
Work tasks to be performed at the site include removal of a crude oil aboveground storage
tank (AST) and its contents, remediation of impacted soils, removal and disposal of
underground storage tanks (USTs) and associated dispensers and piping, destruction of a
Class V shallow disposal well, removal and disposal of septic tank systems, sumps and floor
drains, destruction of water supply wells and groundwater monitoring wells, reabandonment of
oil production wells and abatement of asbestos containing materials (ACMs).
Shallow soils at the project site have been impacted by total recoverable petroleum
hydrocarbons (TRPH), total petroleum hydrocarbons quantified as diesel (TPH-d) and motor oil
(TPHomo). These chemicals of concern (COCs) are associated with the underground storage
tanks (USTs), dispensers and piping on the Sparks parcel and former automobile maintenance
facilities and truck parking across the site. Both hazardous and non-hazardous wastes
associated with past site activities will be removed from the site.
Proposed cleanup objectives for soil at the site have been developed that incorporate
regulatory guidelines and requirements to protect human health and the environment. For the
Rosedale Highway site, it is proposed to use a cleanup goal of 1,000 milligrams per kilogram
(mg/kg) for TPH-d and TPH-mo for unsaturated soil.
Analysis of groundwater samples collected from boreholes and "permanent" groundwater
monitoring wells indicate that groundwater has generally not been impacted across the site.
Xylenes, toluene, methyl tertiary butyl ether (MtBE) and trimethylbenzene (TMB) have been
detected in groundwater samples collected from the monitoring wells located on the eastern
portion of the Sparks parcel and TPH quantified as gasoline (TPH-g) has been detected in
samples collected from the water supply well located on the Rosedale Hotel/Maaco parcel. The
concentrations of these compounds were below generally accepted "action levels" of 1,750
micrograms per liter (IJg/L) for xylenes, 150 IJg/L for toluene, 5 IJg/L for MtBE, 2 pg/L for TMB
and 100 IJg/L for TPH-g. The action levels noted for xylenes, toluene,. MtBE and TMB are
California drinking water Maximum Contaminant Levels (MCLs). The action level for TPH-g is
the state taste and odor threshold level. Based on the available analytical data, ENSR
anticipates that the site will not require.groundwater remediation.

1.0 INTRODUCTION
ENSR Corporation (ENSR) prepared this Removal Action Workplan (RAW) on behalf of Costco
Wholesale for the Rosedale Highway Property (referred to in this document as the "project site"
or "site") located at 2800 Standard Street and 3650 through 3880 Rosedale Highway in
Bakersfield, California. The approximately 20-acre site consists of five parcels referred to as
the Sparks (comprised of two parcels), Rosedale Hotel/Maaco, Seaton and Glen Rose parcels.
The Site Vicinity Map is presented as Figure 1 and the Site Plan as Figure 2.
1.1 Sampling Activities
Extensive sampling activities have been performed at the site since 1989. These activities
included collection and analysis of samples of the crude oil AST contents; collection and
analysis of soil and groundwater samples from across the site; and collection and analysis of
sludge samples from the shallow disposal well, steam cleaner'sump and floor drains. Sampling
locations are shown on the Sample Location Map - Figure 3. The results of the environmental
assessments are summarized below. For clarity, the results for the crude oil AST contents are
discussed separately from the results of the soil, groundwater and sludge sampling.
Sampling of Crude Oil AST Contents
Between 1989 and 1997, various consultants collected samples of the water, oil and sludge
contained inside the crude oil AST. A total of ten samples of the oil phase, nine samples of the
water phase and 28 samples of the sludge phase have been analyzed to date. Leachable
benzene was present in two of the sludge samples collected by Park Environmental Corporation
(Park Environmental), at concentrations slightly above the Toxicity Characteristic Leaching
Potential (TCLP) of 500 pg/L' (the level above which a material would be considered a hazardous
waste). The concentrations of metals in the sludge samples were below their respective Total
Threshold Limit Concentrations (TTLCs); however, soluble lead was present in one sludge sample
at a concentration just above the Soluble Threshold Limit Concentration (STLC).
Based on the analytical results and statistical analysis performed by Kennedy Jenks
Consultants (KJC), the contents of the tank were characterized as non-hazardous.
According to available information, the crude oil AST contains an estimated 400,000 gallons of
water, approximately 100,000 gallons of crude oil and approximately 420,000 gallons of sludge.
Sampling of Sludge, Soil and Groundwater
Extensive environmental subsurface investigations have been conducted at the site over the
past 7 years by various consultants. Investigative tasks at the site have included advancement
of 47 deep soil borings and 18 shallow soil. borings, collection and analysis of 110 subsurface
soil samples and 12 "reconnaissance" groundwater samples, installation of three groundwater

monitoring wells and collection and analysis of groundwater samples from the three monitoring
wells and two water supply wells.
Sludge samples were collected from the Class V shallow disposal well on the Sparks parcel, the
septic tanks located on the Sparks, Rosedale Hotel/Maaco and Glen Rose parcels, the steam
cleaner sump on the Glen Rose parcel and two floor drains in the building located on the
Rosedale Hotel/Maaco parcel. Analysis of these sludge samples revealed hazardous
concentrations of total and/or soluble metals in the steam cleaner sump and floor drains.
Analysis of soil samples collected from across the site revealed concentrations of total
petroleum hydrocarbons quantified as diesel (TPH-d) and motor oil (TPH-mo) above 1,000
mg/kg at five locations. These locations include the perimeter of the crude oil AST, north of the
crude oil AST at the site's northern border (in the area below the former overhead pipeline that
connected the AST to the adjacent refinery), north of the service garage on the Sparks parcel
and two locations on the western portion of the Seaton parcel.
Analysis of groundwater samples collected from "permanent" groundwater monitoring wells
installed on the eastern portion of the Sparks parcel revealed the presence of xylenes, toluene,
MtBE and TMB. In addition, TPH-g was detected in samples collected from the water supply
well located on the Rosedale Hotel/Maaco parcel. The concentrations of these compounds
were below generally accepted "action levels". "Reconnaissance" groundwater samples were
collected from 12 borings advanced across the site by ENSR. No detectable concentrations
above laboratory reporting limits of the analytes tested for were present in these
reconnaissance groundwater samples. Based on the available analytical data, ENSR
anticipates that groundwater remediation will not be required at the site.
In addition, surveys completed by AKRI Corporation (AKRI) for the on-site buildings revealed
the presence of ACMs. A copy of AKRI's report is presented in Appendix A.
1.2 Objective and Purpose
The objective of the RAW is to identify areas on the site that require remediation or completion
of tasks in a manner that is technically and economically appropriate for the site with regard to
protection of human health and the environment. The purpose of this RAW is to outline the
steps to be completed to address environmental concerns at the site prior to redevelopment.
These steps take into account the analytical data and proposed redevelopment at the site.
The planned activities at the site include:

2.2 Site History
The Sparks parcel, addressed as 2800 Standard Street, was most recently occupied by
Minyard Trucking. Past uses of the Sparks parcel include oil fields that operated as early as
1937, with a large sump in the northwest corner of parcel, the Trico oil production well in the
middle section, two ASTs in the northeast section, several smaller ASTs in the southern
section and a large warehouse in the middle section. Between 1952 and 1956, the large
sump was removed, the Trico oil production well was abandoned, the ASTs were removed,
two Phillip's oil wells were installed and an oil field service building was constructed on this
parcel. Between 1956 and 1975, the large warehouse in the middle section of the parcel was
removed and, in 1979, a 2.1 million gallon crude oil AST (referred to as Tank 50001 in
previous documents) and a smaller crude oil AST were constructed on the western portion of
the parcel.
In 1981, the truck service building currently present on the eastern portion of the Sparks
parcel was constructed and piping was installed between the two crude oil ASTs and the
abutting refinery to the north. Between 1981 and 1990, the piping connecting the crude oil
ASTs to the adjacent refinery and the small crude oil AST were removed. The large AST was
left in place.
The Rosedale Hotel is listed as the current property owner of the Rosedale Hotel/Maaco
parcel. This parcel, addressed as 3650/3660 Rosedale Highway, was occupied by residential
buildings prior to construction of the current on-site building in 1982. This building was
occupied by Maaco Auto Paint from the time of its construction until several years ago. The
parcel was used for residential housing as early as 1937, with more residential buildings
constructed on the parcel between 1956 and 1981. By 1982, the residential buildings were
demolished and the building that was used by Maaco Auto Paint was constructed on the
parcel. A Class V shallow disposal well located on the east side of the Maaco Auto Paint
building was destroyed according to Kern County Environmental Health Services Department
(KCEHSD) standards on October 8, 1993.
The Seaton parcel, located between the Rosedale Hotel/Maaco and Glen Rose parcels along
the Rosedale Highway, has been vacant or used for truck parking since as early as 1937.

The Glen Rose parcel, addressed 3800/3880 Rosedale Highway, was used to store oil field
equipment prior to 1964. The current on-site building was constructed in 1964 and was
occupied between 1964 and 2000 by Glen Rose Engine Shop. A Class V shallow disposal
well located on the north side of the building was destroyed according to KCEHSD standards
on September 16, 1994.
2.3 Previous Site Assessments/Investigations
A Phase I environmental site assessment (ESA) report was prepared by KJC and dated
October 22, 1997. KJC prepared recommendations based upon findings from the Phase I ESA
that included the following:
· Completion of an asbestos survey of all on-site buildings;
· Clearing/disposal of debris;
· Removal of the five USTs on the Sparks parcel;
· Sampling of stained soils across the site;
· Sampling/charecterization of the crude oil AST contents;
· Abandonment of water supply wells;
· Removal of septic systems; and
· Removal of drains and sumps.
Numerous sampling activities have been performed at the site, including collection and analysis
of samPles of the crude oil AST contents; collection and analysis of soil and groundwater
samples from across the site; and collection and analysis of sludge samples from the shallow
disposal well, steam cleaner sumP and floor drains. In addition, an asbestos survey of the on-
site buildings was performed by AKRI. The remaining tasks recommended by KJC have not
been performed, and are addressed in this workplan. The results of the previous site
assessments are summarized below. For clarity, the results for the crude oil AST contents are
discussed separately (and first) from the results of the soil, groundwater and sludge samples.
Sampling of Crude Oil AST Contents
Samples of the water, oil and sludge phases were collected in the past for analysis by
Cal/VVestern Fuels, Park and KJC. These samples were analyzed for Title 22/CAM 17 metals,
soluble lead and mercury, the aromatic hydrocarbons benzene, toluene, ethylbenzene and
xylenes (BTEX); leachable benzene and leachable 1,2-dichloroethane (1,2-DCA); chromium
and lead; organochlorinated pesticides and/or PCB's and reactive sulfide, reactive cyanide, pH,
fish bioassay and flash point. Analytical results of the contents are presented in the tables from
previous reports presented in Appendix A.

Samples collected between 1989 and 1991 were analyzed for Title 22/CAM 17 metals (using
TTLC and STLC analytical methods), BTEX, 1,2-DCA and flash point. In addition, one sludge
sample was analyzed for leachable lead using TCLP analysis. Analytical results are
summarized in the tables from previous reports presented Appendix A. These chemicals of
concern (COCs) were not present in the samples analyzed at concentrations at or above their
respective TTLCs, STLCs or TCLPs.
In 1993, Park Environmental performed the first environmental assessment of the site which
included collection and analysis of samples from the crude oil AST (see Park's Table 3 in
Appendix A). Park Environmental collected two samples of the oil phase (designated T-1 and
T-2) and two samples of the sludge phase (designated T-3 and T-4) from the crude, oil AST.
These four samples were analyzed for total recoverable petroleum hydrocarbons (TRPH),
BTEX, leachable benzene using TCLP analysis and Title 22/CAM 17 metals. Petroleum
hydrocarbons and BTEX were present in all of the samples. Leachable benzene was present in
the sludge samples T-3 and T-4 at concentrations of 690 and 750 I~g/kg, respectively. These
concentrations are above the TCLP of 500 IJg/L for leachable benzene. The concentrations of
metals were below their respective TTLCs.
Additional samples of the tank contents were collected in 1997 by KJC and findings were
reported in a waste classification information report dated March 1998. This work was
performed in accordance with a California Department of Toxic Substances Control (DTSC)
approved sampling workplan. These samples were analyzed for BTEX, 1,2-DCA, 2-
methylnapthalene, fish bioassay, reactive sulfide, reactive cyanide, pH, flash point, Title
22/CAM 17 metals (TI'LC), soluble lead, mercury and barium using STLC analysis, PCBs,
organochlorine pesticides, leachable benzene and 1,2-DCA using TCLP analysis, and
leachable chromium and lead using TCLP analysis.
DTSC reviewed the w~ste classification information report by KJC and requested additional
analytical data for hexavalent chromium in the water.phase, and lead and benzene in the
sludge phase. In response to this request, KJC collected three water samples and eight sludge
samples from the AST and reported the results in a waste classification information addendum
dated March 21, 1998.
Based on these analyses, the only COC above "action levels" was soluble lead detected in one
sludge sample at a concentration above the STLC. Based on the analytical results and
statistical analysis performed by KJC, the contents of the tank were characterized as non-
hazardous. Results of the analysis are presented in the tables prepared by KJC and included
in Appendix A.
Additionally, KJC prepared a workplan for the removal and demolition of the crude oil AST
(Tank 50001) dated March 12, 1998. The workplan was reviewed by the DTSC and the DTSC
stated that they had no objections to the workplan in a letter dated March 30, 1998. According
to the workplan, an estimated 400,000 gallons of water would be removed from the AST,
approximately 100,000 gallons of crude oil would be removed and recycled, approximately
420,000 gallons of sludge would be solidified and removed, the AST's interior would be

decontaminated (with proper disposal of rinsate) and the AST would be cut into pieces and
transported to a metal recycler. Based on the workplan by KJC and recent conversations
between ENSR and DTSC representatives, the waste oil is to be disposed of at a DTSC
permitted facility.
Sampling of Sludge, Soil and Groundwater
During Park's 1993 environmental assessment of the Sparks parcel, soil samples were
collected at depths of 15 to 35 feet below ground surface (bgs) from four borings (designated
borings 1 through 4) located near the USTs. Analysis of these samples for fuel fingerprint
(gasoline, diesel, motor oil and crude oil) revealed no detectable concentrations of petroleum
hydrocarbons in these samples (see table from Park's report in Appendix A).
The soil samples collected at depths of 20 a~d 30 feet bgs from the boring (Boring 5) advanced
by Park at the wash rack leach field were analyzed for fuel fingerprint. Analyses of these
samples revealed total petroleum hydrocarbons as crude oil (TPH-co) at a concentration of 53
mg/kg and TPH-d at 14 mg/kg. Samples collected at a depth of 1 foot bgs from around the
crude oil AST (sample locations S-1 through S-5) were analyzed for TRPH, BTEX and Title
22/CAM 17 metals. TRPH was detected at concentrations above 1,000 mg/kg in four of the five
samples. Various metals were detected in each of the samples at concentration below their
respective TTLCs. In addition, BTEX compounds were detected in concentrations below action
levels in four of the five samples; the remaining sample did not contain BTEX compounds at
concentrations at or above the laboratory reporting limits.
Soils Engineering, Inc. (SEI) advanced 31 borings across the site in 1998. Three of the borings
(B28, B29 and B-30) located on the Sparks parcel were converted to groundwater monitoring
wells (MW-l, MW-2 and MW-3). A total of 64 soil samples and three groundwater samples
were collected by SEI for analysis. Soil samples were analyzed for TRPH, TPH-g, TPH-d,
BTEX, MtBE, volatile organic compounds (VOCs), Semi-VOCs, metals, organochlorine
pesticides and/or PCBs. Petroleum hydrocarbons were detected in two of the shallow soil
samples (collected at the 1 foot depth) at concentrations above 1,000 mg/kg. These samples
were collected from borings located on the Seaton parcel and designated B-15 and B-16.
Analysis of the groundwater samples for TPH-g, TPH-d, TRPH, VOCs and/or metals revealed
Iow levels of some petroleum hydrocarbon constituents. The concentrations of these
compounds were below generally accepted "action levels" (MCLs and taste/odor threshold).
Samples of liquid and sludge were also collected for analysis by SEI from the Class V shallow
disposal well on the Sparks parcel, the septic tanks on the Sparks, Rosedale Hotel/Maaco and
Glen Rose parcels, the steam cleaner sump on the Glen Rose parcel and two floor drains on
the 'Rosedale Hotel/Maaco parcel. The liquid and sludge in the shallow disposal well were
characterized as non-hazardous while the sludge in the steam cleaner sump and two floors
were characterized as hazardous based on the soluble metals analyses.
ENSR performed a subsurface investigation at the site during the summer of 2000. A total of
12 borings were advanced to groundwater for collection of soil and groundwater samples and

3.0 PROPOSED CLEANUP OBJECTIVES AND GOALS FOR SOIL
Remedial actions at impacted sites should achieve a level of cleanup that is protective of
human health and the environment. The cleanup objectives and goals proposed should be
selected so that water quality is not threatened and so that applicable regulations are satisfied.
These goals are also based on the proposed site use (ie. commercial versus residential).
3.1 Chemicals of Concern in Soil
Chemicals of concern at the project site include TRPH TPH-d, TPH-mo. The total petroleum
hydrocarbons are likely from on-site sources (i.e., above ground oil storage, the USTs, above
ground piping between the crude oil ASTs and the adjacent refinery, and vehicle maintenance).
Analysis of groundwater samples from the three "permanent" monitoring wells revealed Iow
levels of petroleum hydrocarbons in the area of the existing USTs on the Sparks parcel;
however, analysis of the 12 "reconnaissance" groundwater samples collected from across the
site did not reveal the presence of petroleum hydrocarbons or VOCs in elevated levels.
3.2 Soil Remedial Action Goals
The California Leaking Underground Fuel Tank (LUFT) Field Manual uses a range of 100 to
10,000 mg/kg for assessing TRPH, TPH-d and TPH-mo environmental impacts (LUFT Task
Force, 1989). The LUFT Field Manual uses the following ranges for BTEX: 0.3 to 1.0 mg/kg
benzene; 0.3 to 50 mg/kg toluene; 1.0 to 50 mg/kg ethylbenzene; and 1.0 to 50 mg/kg total
xylenes. However, determinations of specific criteria for required additional characterization
and/or remediation are assessed on a case-by-case, site-specific basis.
Benzene and toluene were not.detected in the on-site soils. The maximum concentrations of
ethylbenzene and total xylenes detected in on-site vadose zone soils were 0.11 mg/kg and 0.71
mg/kg, respectively. Thus, these chemicals were not detected at concentrations in excess of
their respective minimum LUFT cleanup criteria.
The maximum concentrations of TRPH, TPH-d and TPH-mo detected in on-site vadose zone
soils were 3,200 mg/kg, 2,600 mg/kg and 1,000 mg/kg, respectively. These compounds were
detected at concentrations in excess of their respective individual minimum LUFT cleanup
criteria. TRPH, TPH-d and TPH-mo are present at four locations in shallow soils, generally
from the surface to a depth of approximately 4 feet bgs.
For the Rosedale Highway project site, a cleanup goal of 1,000 mg/kg is proposed for TRPH
(noted during previous assessments), TPH-d and TPH-mo in unsaturated soil. This cleanup
goal is judged to be sufficiently protective of a commercial site that is to be developed as a
commercial property covered by buildings, pavements and landscaped areas.

4.0 REMEDIAL/WORK TASKS
A description of the planned activities is presented in this section. For clarity, related
remedial/work tasks are discussed together. Quantity estimates of impacted soils are based on
information presented in reports prepared for the project site by other consultants, ENSR's work
at the site and soil analytical data.
4.'1 AST and Contents
The 2.1 million gallon crude oil AST located on the Sparks parcel contains approximately
920,000 gallons of crude oil, water and oily sediment/sludge. Analysis of soil samples collected
around the perimeter of the AST (S-1-1, S-2-1, S-3-1 and S-5-1) revealed petroleum
hydrocarbons at concentrations up to 3,200 mg/kg. ENSR estimates that approximately 1,500
to 2,000 tons of soil will need to be excavated from beneath the AST, assuming impacted soil
beneath AST is present to a depth of approximately 2 feet. It is anticipated that the excavated
soil will be disposed as non-hazardous waste; samples of the excavated soil will be collected by
the Consultant for analysis to evaluate disposal options. Confirmation sampling will be
performed by the Consultant following excavation to confirm that soil containing petroleum
hydrocarbons above the cleanup goal have been removed from each area.
ENSR proposes to remove the contents of the AST through the following:
· Removal of approximately 100,000 gallons of crude oil by vacuum truck, to be sent to a
licensed oil recycler;
Removal and decanting of approximately 400,000 gallons of water, to be tested and
released into the City of Bakersfield Public Works Department (COBPWD) sewer system
or removal from the site for disposal;
Removal of approximately 420,000 gallons of oily sludge and sediment by one or more
methods including, but not necessarily limited to, solidification by mechanical means (the
mixing with clean fill) and off-site disposal; mixing with oil and transporting to a facility that
can use the material as a fuel; and/or transporting to a facility where the material will be
converted into road base;
Decontaminating the AST's interior with high pressure steam rinsing;
Cutting the AST into pie(~es that can be transported by truck to a metal recycler and
demolition of the concrete ring around the perimeter of the AST for off site disposal or
recycling (concrete estimated at 300 tons); and
· Removal of 1,500 to 2,000 tons of impacted soil below the AST (based on assumption
that impacted soil is present beneath area of AST to depth of approximately 2 feet).

A detailed scope of work for this task is presented in Appendix B.
4.2 Impacted Soils
Elevated concentrations (above 1,000 mg/kg) of petroleum hydrocarbons were detected in the
following samples:
· EB-I-1;
· ES-10-4;
· B-15-1; and
· B-16-1.
Samples EB-I-1 and ES-10-4 were collected from the Sparks parcel and B-15-1 and B-16-1
from the Seaton parcel. Analysis of these soil samples revealed petroleum hydrocarbons at
concentrations up to 2,600 mg/kg. ENSR estimates the following soil quantities will need to be
re moved:
· Approximately 40 to 50 tons (15 foot diameter and 3 foot depth) of impacted soil in the
area of EB-1;
Approximately 125 to 150 tons (10 foot by 50 foot by 5 foot depth) of impacted soils in the
area of ES-10;
Approximately 5 to 10 tons (6.5 foot diameter by 2 fbot depth) of impacted soils in the
area of B-15; and
· Approximately 20 to 30 tons (15 foot diameter by 1.5 foot depth) of impacted soils in the
area of B-16.
It is anticipated that the excavated soil will be disposed as non-hazardous waste; samples of
the excavated soil will be collected by the Consultant for analysis to evaluate disposal options.
Confirmation sampling will be performed by the Consultant following excavation to confirm that
soil containing petroleum hydrocarbons above the cleanup goal have been removed from each
area.
Appendix C contains the detailed scope of work for removal of the impacted soils.
4.3 Underground Storage Tanks
Five USTs are currently located on the Sparks parcel, including two 8,000-gallon gasoline
USTs, one 10,000-gallon gasoline UST, one 10,000-gallon diesel UST and one 1,000-gallon
waste oil UST.
Approximately 300 to 400 tons of impacted soils are expected at the USTs and fuel dispensers,
based on analysis of soil samples collected from nearby borings (B-5 and B-10). it is anticipated

that this soil will be disposed of as non-hazardous waste, based on available data. Confirmation
sampling will be performed by the Consultant following excavation to confirm that soil containing
petroleum hydrocarbons above the cleanup goal have been removed from each area.
A detailed scope of work for removal of the USTs is presented in Appendix D.
4.4 Clarifier and Class V Shallow Disposal Well
A clarifier and Class V shallow disposal well are located on the Sparks parcel on the south side
of the service garage. Approximately 15 tons of liquid and sludge is estimated to be present in
the shallow disposal well. Liquid and sludge samples (UIC-L and UIC-S) collected from the
clarifier and Class V shallow disposal well indicate that the liquid and sludge in the clarifier and
Class V shallow disposal wel~ can be treated as non-hazardous waste. In addition, ENSR
anticipates that approximately 75 to 100 tons of soil in the area of the clarifier and shallow
disposal well will require excavation and off-site disposal. Based on analysis of soil samples
collected, from borings B-2, B-3, B-4 and B-30, it is anticipated that the excavated soil will be
treated as non-hazardous waste. In addition, approximately 10 tons of concrete will be
removed from the site for disposal or recycling.
Confirmation sampling will be performed by the Consultant following excavation to confirm that
impacted soil have been removed from the area.
Appendix E presents the scope of work for destruction of this well.
4.5 Septic Systems
Up to four septic systems (tank and associated leach field) are present on the project site,
including one septic system located south of the fuel dispenser island (west of the service
garage) on the Sparks parcel, one system suspected to be located near the trailer to the
southwest of the service garage on the Sparks parcel and one system each on the Rosedale
Hotel/Maaco parcel and Glen Rose parcel. ENSR estimates that approximately 200 to 250 tons
of material (including sludge in tank, tank, drain lines and impacted soil) will need to be
removed for each septic system to expose drain lines and impacted soil, if any. This includes
approximately 100 to 150 tons of soil from each septic system that are expected to be disposed
of as non-hazardous waste (based on analysis of soil samples collected from borings B-27, B-
28, B-17, HA-l, B-18 and B-19) and approximately 100 tons of concrete and piping materials
from each septic system that will be disposed of as construction debris.
Confirmation sampling will be performed by the Consultant following excavation to confirm that
impacted soil have been removed from the area.
A detailed scope of work for removal of the septic systems is presented in Appendix F.

4.6 Sumps
A steam cleaner sump is present at the northwest corner of the building on the Glen Rose
parcel. Analysis of a sludge sample (SCS-SL) collected from the sump revealed that
hazardous concentrations of soluble lead and cadmium are present in the sludge. ENSR
estimates approximately 7.5 tons of sludge will be removed as hazardous waste. Based on
analysis of soil samples collected from borings (B-22 and B-23), it is expected that soil removed
from the area will be non-hazardous. It is anticipated that 10 to 20 tons of soil will be removed
from beneath the steam cleaner sump. In addition, approximately 10 tons of concrete will be
removed for off site disposal or recycling.
One large drilling sump and two small drilling sumps are located on the site. Limited
information is available on these sumps; it is anticipated that these sumps may contain drilling
mud, crude oil and possibly other petroleum hydrocarbons. The contents are expected to be
classified as non-hazardous. Each of the smaller sumps likely contain up to 300 tons of
material while the large sump likely contains up to 750 tons of materials. No soil samples have
been collected from the areas of the drilling sumps; however, we anticipate that up to 75 tons of
concrete and 25 to 50 tons of impacted soil (non-hazardous) will be removed in conjunction with
the large drilling sump and up to 40 tons of concrete and 15 to 25 tons of impacted soil (non-
hazardous) will be removed in conjunction with each of the two small drilling sumps.
Confirmation sampling will be performed by the Consultant following excavation to confirm that
impacted soil have been removed from the area.
Details of removal of the sumps are presented in Appendix G.
4.7 Floor Drains
Analysis of sludge contained in two floor drains located inside the building on the Rosedale
Hotel/Maaco parcel revealed soluble concentrations of cadmium, barium and lead above STLC.
These samples, designated Ftr-D-N and FIr-D-SE, indicate that the sludge is to be treated as
hazardous waste. ENSR estimates approximately 1 ton of sludge will be removed from the
floor drains in the Maaco building. No soil samples have been collected from beneath the floor
drains; however, we anticipate that 10 to 20 tons of soil will be removed from beneath the floor
drains. In addition, approximately 20 tons of concrete will be removed for off site disposal or
recycling.
Confirmation sampling will be performed by the Consultant following excavation to confirm that
impacted soil have been removed from the area and from excaVated soil to assess disposal
options.
The scope of work for removal of the sludge and floor drains is presented in Appendix H.

4,8 Water Supply Wells
Four water supply wells are present on the site, including the following:
Sparks parcel:
· One 60 foot deep water well that is 16 inches in diameter; and
· One 140 foot deep water well that is 6 inches in diameter.
Glen Rose parcel:
· One 280 foot deep water well that is 8 inches in diameter.
Seaton parcel:
· One 280 foot deep water well that is 8 inches in diameter.
The detailed scope of work for destruction of the water supply wells is presented in Appendix I.
4.9 Groundwater Monitoring Wells
Three groundwater monitoring wells were installed on the eastern portion of the Sparks parcel
in 1998. These wells, designated MW-l, MW-2, and MW-3, are each 35 feet deep and 8
inches in diameter.
The wells will be properly destroyed (see scope of work presented in Appendix J).
4.10 Oil Production Wells
Three oil production wells were drilled on the Sparks parcel in the past. These weqs,
designated Trico Oil Well, Phillips Oil' Well #1 and Phillips Oil Well #2, were abandoned in 1955
(Trico) and 1960 (Phillips).
The procedure outlined in Appendix K will be followed for assessing if the oil wells are to be
replugged and reabandoned and, if so, the methods to be employed during this work. ENSR
will consult with the local office of the Department of Oil and Gas to establish if these wells are
required to be replugged and reabandoned prior to site redevelopment.
4.11 Drums and Miscellaneous Debris
Debris present on the site consists of miscellaneous tires, asphalt, trash, buckets, concrete with
oil staining and scrap metal. These materials will be removed from the site for proper disposal.
It is anticipated that the materials will be removed as non-hazardous unless otherwise noted.
ENSR estimates the following amounts of drums and debris will need to be removed from the
site:

Additional Comments:
Floor tile and sheet floodng matedal mastics are suspected asbestos-containing
materials. However, to avoid excessive damage to floor tiles and sheet flooring
materials, we did not collect any samples of mastic under floor tiles or sheet flooring
matedals.

REMOVAL OF CRUDE OIL ABOVEGROUND STORAGE TANK
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. A 2.1 million gallon aboveground
storage tank (AST) is present on the Sparks parcel. According to available information, the
contents of this AST have separated into layers. The AST currently contains approximately
100,000 gallons of crude oil, 400,000 gallons of water and 420,000 gallons of oily sediment and
sludge for a total of approximately 920,000 gallons.
1.0 AST Contents
Samples of the various phases contained in the AST have been analyzed in the past. The
results are presented in Appendix A of the Removal Action Workplan (RAW) prepared for the
site by ENSR International (ENSR).
A workplan for removal and disposal of the AST contents and demolition of the AST was
prepared by Kennedy Jenks Consultants (KJC). That document, titled Workplan, Sparks Estate
Property, 50,000 Barrel Tank, Content Removal and Demolition dated March 12, 1998 outlined
the scope of work proposed by KJC. We have adopted this workplan pending receipt of
alternative methods proposed by contractors. The work included removal and transportation of
the oil phase to a licensed recycling facility, discharge of the water to the City of Bakersfield
sanitary sewer, and solidification and disposal of the sludge at an appropriate disposal facility.
A copy of KJC's workplan was previously provided to the California Department of Toxic
Substances Control and the Kern County Environmental Health Department; a copy of this
workplan is enclosed herewith.
If KJC's work plan is implemented, the oil phase will be pumped out of the AST using a vacuum
truck. Five composite samples of the water phase will be collected from the temporary storage
tanks during the initial sampling round to evaluate compliance with the City of Bakersfield waste
water discharge requirements. Collection and analysis of additional samples of the sludge
phase will not be performed as a sufficient number of samples have been collected in the past
to characterize this material.
Based on ENSR's discussions with contractors, alternative methods for disposal/recycling of the
AST contents are possible, including disposal of the water phase at an off-site facility, blending
of oil phase and sludge phase as fuel for use by an off-site facility or transport of the material to
an off-site facility for conversion to a road base material. The bid documents to be distributed
to contractors invited to bid on this work state that alternatives to KJC's workplan will be
evaluated by ENSR and discussed with the regulatory agency for applicability at the site.
ENSR will forward a revised workplan to the regulatory agency if the proposed disposal of the
AST contents varies from that outlined in KJC's work plan.

2.0 Tank Demolition
The AST will be decontaminated after the contents have been removed and prior to the tank's
demolition. Rinsate produced during cleaning of the AST will be sampled and removed from the
site for proper disposal or recycling. The steel will be cut into pieces of appropriate size for
loading onto trucks for transportation to a local metal recycling facility.
The concrete ring wall beneath the perimeter of the AST will then be demolished for off site
removal. The concrete will be broken into pieces of appropriate size for loading onto trucks for'
transportation to a local concrete recycling facility. Approximately 300 tons of concrete will be
removed for off site disposal or recycling.
3.0 Impacted Soils
Based on analysis of soil samples collected from the perimeter of the AST, soils impacted with
petroleum hydrocarbons are present around the AST. Soils with petroleum hydrocarbons in
excess of 1,000 mg/kg will be remediated by removal of the soil from the site for off-site
disposal. Necessary permits will be obtained from appropriate agencies, including but not
necessarily limited to, the City of Bakersfield Building Department for excavation and backfill
work. The activities will be conducted in accordance with the permit conditions and Health and
Safety Plan (HASP) and work plans prepared by ENSR and ENSR's subcontractors.
It is anticipated that soils beneath and around the AST to a depth of approximately 2 feet are
impacted with petroleum hydrocarbons for a total of approximately 1,500 to 2,000 tons. The
impacted soil will be removed using a backhoe and stockpiled on-site. Excavation will continue
until analytical results indicate that soils containing petroleum hydrocarbons at concentrations
above 1,000 mg/kg have been removed. It is anticipated that the soil will be disposed of as non-
hazardous waste. The soil will be sampled by the Consultant to evaiuate appropriate disposal
options.
3.1 Soil Sampling
One four point composite will be collected from each 300 tons of impacted soil for chemical
analysis. The Consultant will review the analytical data to evaluate appropriate disposal options.
Up to twelve soil samples will be collected by ENSR personnel from the sidewalls and floor of
the excavation using hand sampling equipment. The sampler, lined with a brass or stainless
steel tube, will be driven into the soil to collect the sample. The ends of the tube will be covered
with a TeflonTM sheet, capped, labeled, and preserved on ice for transport to the laboratory.
Chain-of-custody procedures will be followed in all phases of sample handling.

3.2 Sample Handling
Each sample will be packaged and transported appropriately,
protocol:
according to the following
Collect samples in appropriately sized and prepared containers;
Attach completed sample label to each sample;
Properly seal and package sample containers;
Complete chain-of-custody/analysis request forms;
Separate and place samples into chilled coolers for shipment to the appropriate laboratory
(samples will be packaged so the potential for shipping damage is minimized);
· Seal the top two copies of the chain-of-custody form inside a zip-lock bag and place inside
the cooler;
· Seal the cooler with several strips of strapping tape; and
· Arrange for appropriate shipment to the analytical laboratory.
3.3 Sample Analyses
The stockpile and confirmation soil Samples will be analyzed for:
· Total Petroleum Hydrocarbons quantified as gasoline (TPH-g) using modified United
States Environmental Protection Agency (EPA) Test Method 8015;
· TPH as diesel (TPH-d) and TPH as motor oil (TPH-mo) using modified EPA Test Method
8015; and
· Benzene, toluene, ethylbenzene and xylenes (BTE×) using EPA Test Method 8020.
3.4 Backfill Activities
Clean imported materials will be brought to the site for use in backfilling the excavation after
removal and sampling activities are completed. The imported material will be approved by
ENSR prior to importation to the site and compacted to 90 percent relative compaction in
accordance with the requirements stated in Kleinfelder, Inc.'s geotechnical investigation for the
site.
4.0 Decontamination Procedures
All equipment used during on-site work that might come into contact with potential chemicals of
concern (COCs) will be thoroughly cleaned before and after each use. This will be
accomplished through steam cleaning and/or washing with Alconox (a ~aboratory-grade

detergent) and rinsing with deionized, distilled or fresh water. All rinseate will be managed and
disposed of properly.
5.0 Instrument Calibration Procedures
During site activities, field data will be collected using field instruments to assess worker
exposure to volatile COCs and field screen soil samples. The protocols for field personnel,
described below, are designed so that field measurements, if made by different individuals, are
consistent and reproducible. Standard equipment calibration procedures for each instrument
are also described.
5.1 Portable Air Monitoring Equipment Calibration
A hand-held portable photo-ionization detector (PID) instrument (such as a Photovac MicroTip)
or a handheld portable flame-ionization (FID) instrument (such as a Foxboro GC128 OVA) will
be used in the field to monitor worker exposure and possibly field-screen soil samples. The PID
instrument or the FID instrument will be used to evaluate volatile organic compounds in soil and
ambient air. The PID instrument is more responsive to volatile compounds with saturated
chemical bonds (i.e., benzene, toluene) in the part per million (ppm) concentration range while
the FID is responsive to volatile/nonvolatile compounds with carbon-hydrogen bonds (i.e.,
methane, trichloroethane, as well as benzene and toluene) in the ppm range.
Calibration of the PID instrument will be performed using the manufacturer-recommended
calibration standard span gas to adjust the span and ambient air for. zero calibration.
Calibration of the FID instrument will be performed, as specified by the .manufacturer, using
ambient air for zero calibration only. Calibration with a span gas, according to the
manufacturer, is not required for instrument use. Calibration of the PID and FID will be
performed before each day's sampling and at intervals throughout the day (approximately every
hour) when irregularities in the readings become apparent.

PROCEDURES FOR REMOVAL AND DISPOSAL
OF IMPACTED SOILS
REMOVAL AND DISPOSAL OF IMPACTED SOILS
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. Soils with petroleum
hydrocarbons concentrations in excess of 1,000 milligrams per kilogram (mg/kg) are present in
four on-site areas. A summary of the analytical results indicating elevated concentrations of
petroleum hydrocarbons in soil is presented below.
Parcel Boring No. Result Quantity 1
Sparks EB-1 (1 ft) TPH-mo: 2,600 mg/kg 40 to 50 tons
Sparks ES-10 (4 ft) TPH-d: 1,200 mg/kg 125 to 150 tons
TPH-mo: 1,000 mg/kg
Seaton B-15 (1 ft) TRPH: 1,400 mg/kg 5 to 10 tons
Seaton B-16 (1 ft) TRPH: 1,800 mg/kg 20 to 30 tons
Notes:
1. Quantities are estimates only.
(1 ft) : Depth (in feet) of soil sample analyzed
mg/kg - Milligrams per kilogram
TPH-mo = Total Petroleum Hydrocarbons quantified as motor oil
TPH-d = Total Petroleum Hydrocarbons quantified as diesel
TRPH = Total Recoverable Petroleum Hydrocarbons
These soil will be remediated as detailed below.
1.0 Remediation Activities
1.1 Remediation Activities
Soils impacted with petroleum hydrocarbons in excess of 1,000 mg/kg will be remediated by
removal of the soil from the site for off-site disposal. Necessary permits will be obtained from
appropriate agencies, including but not necessarily limited to, the City of Bakersfield Building
Department for excavation and backfill work. The activities will be conducted in accordance
with the permit conditions and Health and Safety Plan (HASP) and work plan prepared by
ENSR and ENSR's subcontractors.
The locations of the areas with impacted soils are shown on Figure 2. The lateral and vertical
extent of impacted soil in these areas has not been established; however, it is anticipated that the
extent is limited due to the concentrations of petroleum hydrocarbons detected in the soil samples
and shallow depths at which petroleum hydrocarbons were detected. The impacted soil will be
removed using a backhoe and stockpiled on site. The soil removed from each excavation will be
C-1
segregated into separate stockpiles. Excavation will continue until analytical results indicate that
soils containing petroleum hydrocarbons at concentrations above 1,000 mg/kg have been
removed. It is anticipated that the soil will be disposed of as non-hazardous waste.
1.2 Soil Sampling
One four point composite will be collected from each soil s~ockpile for chemical analysis. These
samples will be collected using hand sampling equipment. The Consultant will review the
analytical data to evaluate appropriate disposal options.
Up to five soil samples will be collected by ENSR personnel from the sidewalls and floors of
each excavation using hand sampling equipment or excavation equipment (i.e. backhoe). The
sampler, lined with a brass or stainless steel tube, will be driven into the soil to collect the
sample. The ends of the tube will be covered with a TeflonTM sheet, capped, labeled, and
preserved on ice for transport to the laboratory. Chain-of-custody procedures will be followed in
all phases of sample handling.
1.3 Sample Handling
Each sample will be packaged
protocol:
and transpoded
appropriately, according
to the following
· Collect samples in appropriately sized and prepared containers;
· Attach completed sample label to each sample;
· Properly seal and package sample containers;
· Complete chain-of-custody/analysis request forms;
· Separate and place samples into chilled coolers for shipment to the appropriate laboratory
(samples will be packaged so the potential for shipping damage is minimized);
· Seal the top two copies of the chain-of-custody form inside a zip-lock bag and place inside
the cooler;
· Seal the cooler with several strips of strapping tape; and
· Arrange for appropriate shipment to the analytical laboratory.
1.4 Sample Analyses
The stockpile and confirmation soil samples will be analyzed for:
· Total Petroleum Hydrocarbons quantified as gasoline (TPH-g) using modified United
States Environmental Protection Agency (EPA) Test Method 8015;
C-2
· TPH as diesel (TPH-d) and TPH as motor oil (TPH-mo) using modified EPA Test Method
8015; and
· Benzene, toluene, ethylbenzene and xylenes (BTEX) using EPA Test Method 8020.
1.5 Backfill Activities
Clean imported materials will be brought to the site for use in backfilling the excavation after
removal and sampling activities are completed. The imported material will be approved by
ENSR prior to importation to the site and compacted to 90 percent relative compaction in
accordance with the requirements stated in Kleinfelder, Inc.'s geotechnical investigation for the

UNDERGROUND STORAGE TANK REMOVAL AND DISPOSAL
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. Five underground storage tanks
(USTs) are present on the Sparks parcel. These USTs include the following:
· Tw° 8,000-gallon gasoline USTs;
· One 10,000-gallon gasoline UST;
· One 10,000-gallon diesel UST; and
· One 1,000-gallon waste oil UST.
These USTs and associated dispensers and piping will be removed as detailed below.
1.0 Underground Storage Tank Removal
1.1 Removal Activities
Prior to commencement of field activities for removal of the USTs, removal permits will be
obtained from the City of Bakersfield Fire Department (BFD). Removal activities will be
conducted in accordance with the permit conditions and Health and Safety Plan (HASP) and
work plan prepared by ENSR and ENSR's subcontractors.
The locations of the USTs are shown on Figure 2. The dispensers and concrete islands will be
removed and disposed as construction debris. The underground piping associated with the
USTs will be triple-rinsed, removed and diSposed with the USTs. The rinsate will be removed
from the site for proper disposal. Removal of the waste oil piping may require partial demolition
of the concrete floor inside the shop building.
Liquid or product remaining in the USTs will be pumped into a vacuum truck and removed from
the site for proper disposal or recycling. Once the dispensers have been removed and it has
been confirmed by the contractor that no liquid or product remains in the USTs, soil covering
the USTs (overburden) will be removed using a backhoe. The top of the USTs will be exposed
but the USTs will not be removed until inspectors from the BFD are present to observe the
activities.
Soils excavated during the UST removal activities will be stockpiled on the site. Soils that
appear to be visually stained or discolored, if any, will be removed from the excavations. The
soils that appear to be impacted will be segregated from soils that exhibit no evidence of
staining or discoloration.
D-1
I
I
I
I
I
I
I
I
I
Once the overburden is removed, dry ice will be used to inert the USTs prior to their removal.
Approximately 200 pounds of dry ice (20 pounds per 1,000 gallons of tank capacity) will be
used for each of the product UST and approximately 20 pounds of dry ice will be used for the
waste oil UST. An explosive gas indicator will be used to confirm that both the lower explosive
limit and the percentage of oxygen within the USTs are below 5%.
After the USTs are removed, ENSR's representatives will visually observe the USTs and holes,
cracks or leaks in the USTs will be documented by ENSR's representative. The USTs will be
removed from the excavation and placed on flatbed trucks permitted for transporting the USTs
to a permitted tank reclamation facility.
Based on analysis of groundwater samples collected from monitoring wells located in the area
of the USTs, ENSR does not anticipate encountering impacted groundwater in the tank
.excavations. Free product, if encountered in an excavation, will be removed using absorbent
booms and a vacuum truck. The product removed from the excavation will be disposed of
properly at an off-site facility.
If groundwater is encountered in an excavation, it will be pumped once before a groundwater
sample is collected and then pumped further as an interim remedial measure. Any groundwater
that collects in the bottom of the excavation will be pumped to temporary holding tanks to
control ponding. The groundwater will be removed from the site for proper disposal or
discharged to the sanitary sewer under proper permits. ~f groundwater is to be discharged to
the sanitary sewer, it will be stored in the tanks for sufficient time to allow suspended sediment
to settle out of the water. Hydrocarbons will be removed by physical means such as granulated
activated carbon (GAC) adsorption or other approved means that will satisfy the sanitary sewer
discharge requirements of the City of Bakersfield. The groundwater will be Sampled prior to
discharge to the sanitary sewer. If sampling results indicate it does not meet discharge
requirements for the sanitary sewer, the groundwater will be disposed of at an off site facility.
1.2 Soil Sampling
Samples will be collected from the stockpiled soil with hand sampling equipment. It is
anticipated that approximately 300 to 400 tons of impacted soil will be excavated during the
tank removals and that this soil will be removed from the site for disposal as non-hazardous
waste. ENSR will collect twelve samples from the soil removed from the excavation to confirm
appropriate disposal methods. The twelve samples will be composited into three samples for
analysis.
Soil samples will be collected from the tanks pits with the use of the excavation equipment and
from below the piping and dispensers using hand sampling equipment. The equipment bucket
will retrieve soil from the excavation to be sampled and bring that soil to ENSR's representative
at the side of the excavation. A brass tube will be driven into the soil in the equipment bucket to
collect the sample. The ends of the tube will be covered with a TeflonTM sheet, capped, labeled,

and preserved on ice for transport to the laboratory. Chain-of-custody procedures will be
followed in all phases of sample handling.
Soil samples will be collected from each sidewall and four samples will be collected from
beneath each of the USTs by the Consultant. The samples from the excavation floors will be
collected at the 2 foot and 6 foot depths from two sampling points located approximately one-
third of the tank length in from each end. In the event visual or olfactory indications of soil
impacts are noted, additional soil sampling of the UST excavations may be required to
adequately characterize the site.
Soil samples will be collected from beneath the product delivery piping at a frequency of
approximately one sample location per 15 linear feet of piping with samples collected at depths
of 2 and 6 feet beneath the piping. In addition, samples will be collected at depths of 2 and 6
feet beneath the piping at the locations of pipe fittings. Two soil samples will be collected
beneath each product dispenser at depths of 2 and 6 feet.
All soils encountered during UST removal activities will be examined and described by ENSR.
ENSR will maintain a written record of these descriptions. Soil will be described in accordance
with the Unified Soil Classification System and standard geologic nomenclature. The sample
log will contain the following information:
· Sample date and time;
· Sample number and location;
· Sample depth;
· Sediment co~or;
· Sediment grain size;
· Estimated relative percentages of grain sizes;
· Descriptive comments;
· Estimated moisture content;
· Odors;
· Other observations; and
· Observer's name.
1.3 Groundwater Sampling
Groundwater encountered in the excavation, if any, will be sampled using either a bailer or a
peristaltic pump. Each groundwater sample will be transferred directly to laboratory prepared
sample containers, labeled, and preserved on ice for transport to the laboratory. Chain-of-
custody procedures will be followed in all phases of sample handling.
1.4 Sample Handling
Each sample will be packaged and transported

· Semi-volatile organic compounds (SVOCs) using EPA Method 8270; and
· Total cadmium, chromium, lead, nickel, and zinc using the appropriate 6000/7000 series
test methods.
Groundwater, if any, present in the excavations will be sampled with the samples analyzed for
the appropriate constituents (see above).
1.6 Backfill Activities
Imported materials (crushed rock and/or clean select granular material) will be brought to the
site and placed in close proximity to the excavations to backfill the tank pits after completion of
the UST removals. The imported materials will be approved by ENSR. It is anticipated that the
excavation for the fuel USTs will measure approximately 55 feet by 35 feet by 15 feet deep.
The imported rock will be placed in the lower portion of the excavation if groundwater is present
and the excavated soil or clean select granular material will be used for backfill above the
groundwater level. The backfill material will be compacted to 90 percent relative compaction in
accordance with the requirements stated in Kleinfelder, Inc.'s geotechnical investigation for the
site.
Obviously stained or odorous material will be sampled to establish if these soils are appropriate
for use as backfill; if analytical results indicate that chemicals of concern are present above site
specific action levels, then the soil will be placed on top of and covered by VisqueneTM. Final
disposition of the stockpiled soil will be dependent upon analytical results of samples collected
from the stockpile. Once analytical results of the samples collected from the tank sites are
received, ENSR will make recommendations regarding further investigation, if required, or site
closure.
2.0 Decontamination Procedures
All equipment used during on-site work that might come into contact with potential chemicals of
concern (COCs) will be thoroughly cleaned before and after each use. This will be
accomplished through steam cleaning and/or washing with Alconox (a laboratory-grade
detergent) and rinsing with deionized, distilled or fresh water. All rinseate will be managed and
disposed of properly.
3.0 Instrument Calibration Procedures
During site activities, field data will be collected using field instruments to assess worker
exposure to volatile COCs, field screen soil samples and assess the atmosphere in the USTs.
The protocols for field personnel, described below, are designed so that field measurements, if
D-5

made by different individuals, are consistent and reproducible. Standard equipment calibration
procedures for each instrument are also described.
3.1 Portable Air Monitoring Equipment Calibration
A hand-held portable photo-ionization detector (PID) instrument (such as a Photovac MicroTip)
or a handheld portable flame-ionization (FID)instrument (such as a Foxboro GC128 OVA) will
be used in the field to monitor worker exposure and possibly field-screen soil samples. The PID
instrument or the .FID instrument will be used to evaluate volatile organic compounds in soil and
ambient air. The PID instrument is more responsive to volatile compounds with saturated
chemical bonds (i.e., benzene, toluene) in the part per million (ppm) concentration range while
the FID is responsive to volatile/nonvolatile compounds with carbon-hydrogen bonds (i.e.,
methane, trichloroethane, as well as benzene and toluene) in the ppm range.
Calibration of the PID instrument will be performed using the manufacturer-recommended
calibration standard span gas to adjust the span and ambient air for zero calibration.
Calibration of the FID instrument will be performed, as specified by the manufacturer, using
ambient air for zero calibration only. Calibration with a span gas, according to the
manufacturer, is not required for instrument use. Calibration of the PID and FID will be
performed before each day's sampling and at intervals throughout the day (approximately every
hour) when irregularities in the readings become apparent.
3.2 O2/LEL Calibration
The oxygen(O2)/Iower explosive limit (LEL) meter is a battery powered portable instrument that
can detect and indicate concentrations of combustible gas or vapor in air, in the percent of
explosibility and parts per million ranges, simultaneously with measurement of oxygen and
detection of oxygen deficiency.
Calibration of the meter is done with hexane of a known concentration. The zero adjust is used
to calibrate the instrument. Calibration for oxygen is done in a fresh air environment. The zero
adjust is set at 21% oxygen.

DESTRUCTION OF CLARIFIER AND CLASS V DISPOSAL WELL
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. A clarifier and Class V disposal
well is located on the Sparks parcel. This well will be destroyed in accordance the United
States Environmental Protection Agency (EPA) publication Guidelines for Closure of Shallow
Disposal Wells.
Based on the available information, the well is approximately 15 feet deep and approximately
one foot in diameter. The casing ~material is not known. Approximately 15 tons of liquid and
sludge are estimated to be present in the clarifier and shallow disposal well. Liquid and sludge
samples (UIC-L and UIC-S) collected from the clarifier and Class V shallow disposal well
indicate that the liquid and sludge in the clarifier and Class V shallow disposal well is to be
treated as .non-hazardous waste. ENSR anticipates that approximately 75 to 100 tons of
impacted soil in the area of the clarifier and shallow disposal well will require excavation and off- '
site disposal. It is anticipated that this soil will be disposed as non-hazardous waste.
Approximately 10 tons of concrete will be removed for off site disposal or recycling.
A summary of the tasks to be completed for the well destruction is presented below.
1.0 Well Destruction
1.1 Well Destruction Activities
The location of the Class V disposal well'is shown on Figure 2. Prior to commencement of field
activities for destruction of the well, a sampling plan will be prepared for submittal to the
regulatory agency. This sampling plan will include the following:
· Types of sampling containers and their preparation;
· Sample preservation methods;
· Sampling equipment and method of sample retrieval;
· Familiarity with specified sampling methods;
· Certified laboratory to be utilized; and
· Copy of a Chain-of-Custody form.
The Bakersfield Fire Department will be contacted at least five (5) days prior to commencement
of well closure activities. Removal activities will be conducted in accordance with the permit
conditions and ENSR's Health and Safety Plan (HASP).
The locations of drains and drain lines leading to the Class V well will be identified and the

of properly. The drain lines will be disconnected from the well and interiors of the drains and
drain lines will be pressure washed with the rinsate, drains and drain lines removed for proper
disposal.
The well casing will be removed by overdrilling or other means after removal of the drain lines
and impacted soils, if any, will be removed for proper disposal. We anticipate that depth of the
well excavation will be approximately 15 to 20 feet below ground surface.
1.2 Soil Sampling
Following removal of the impacted soil, if any, a soil sample will be collected from the center of
the excavation floor (bottom of the well) using excavation or drilling equipment. If excavation
equipment is used, the bucket will retrieve soil from the area to be sampled and bring that soil
to ENSR's representative at the side of the excavation. A brass tube will be driven into the soil
in the equipment bucket to collect the sample. The ends of the tube will be covered with a
TeflonTM sheet, capped, labeled, and preserved on ice for transport to the laboratory. Chain-of-
custody procedures will be followed in all phases of sample handling.
Two four point composites will be collected from the soil stockpile for chemical analysis using
hand sampling equipment. The Consultant will review the analytical data to evaluate
appropriate disposal options.
1.3 Sample Handling
Each sample will be packaged and transported appropriately, according
protocol:
to the following
Collect samples in appropriately sized and prepared containers;
Attach completed sample label to each sample;
Properly seal and package sample containers;

REMOVAL OF SEPTIc SYSTEMS
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. Several septic systems,
comprised of a septic tank and associated leach field, are located on the site. One septic
system is known to be present on the Sparks parcel (servicing the shop building) and one
septic system is suspected to exist at the trailer. In addition, one system is located on the
Rosedale Hotel/Maaco parcel and one system is present on the Glen Rose parcel. These
septic systems will be destroyed in accordance the United States Environmental Protection
Agency (EPA) publication Guidelines for Closure of Shallow Disposal Wells. Additional permits
will be obtained by ENSR's subcontractors as appropriate, including but not necessarily limited
to, excavation and backfill permits from the City of Bakersfield Building Department.
ENSR estimates that approximately 200 to 250 tons of waste material (including sludge in tank,
tank, drain lines and impacted soil) will be produced for each septic system. This includes
approximately 100 to 150 tons of soil that are expected to be disposed of as non-hazardous
waste and approximately 100 tons of concrete and piping materials that Will be disposed of as
construction debris.
A summary of the tasks to be completed for the removal of the septic systems is presented
below.
1.0 Septic System Removal
1.1 Removal Activities

The locations of septic tanks and their associated leach fields will be identified and the contents
of the tanks will be removed of by pumping or other means and disposed of properly (this
material has been characterized as non-hazardous). The tanks will then be pressure washed
and the rinsate and tanks removed for proper disposal as construction debris. The drain lines
of the leach fields will then be removed for proper disposal as construction debris.
Visibly impacted soils, if any, present beneath the tanks and leach fields will be removed for
proper disposal. Based on available analytical results of soil samples collected from the area of
the leach fields, impacted soil is not anticipated in these areas.
1.2 Soil Sampling
Following removal of the impacted soil, if any, soil samples will be collected from the former
tank and leach field excavation floors using hand sampling equipment. Soil samples will be
collected from the floor of the tank excavation at the end located nearest the structure.
Samples will be collected from this location at depths of approximately 1 foot and 5 feet below
the excavation floor. Soil samples will also be collected at depths of approximately 1 foot and 5
feet below the leach field excavation floor at 20 foot intervals along the length of the drain lines.
Soil samples will be collected by ENSR personnel from the excavations using hand sampling
equipment and, if any excavations extend to depths greater than four feet bgs, samples will be
taken from the backhoe bucket.
The soil from each septic system will be stockpiled separately. Eight soil samples will be
collected from each stockpile and composited into two samples for chemical analysis.
Following collection of the samples, the ends of the tube will be covered with a TeflonTM sheet,
capped, labeled, and preserved on ice for transport to the laboratory. Chain-of-custody
procedures will be followed in all phases of sample handling. The Consultant will review the
analytical data to evaluate appropriate disposal options.

REMOVAL OF SUMPS
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. A steam cleaner sump is located on
the Glen Rose parcel. In addition, one large drilling sump and two small drilling sumps are
located on the site. Limited information is available on the drilling sumps; it is anticipated that
these sumps may contain drilling mud, crude oil and possibly other petroleum hydrocarbons.
These sumps will be removed in accordance with applicable regulations. Permits will be obtained
by ENSR subcontractors as appropriate, including but not necessarily limited to, excavation and
backfill permits from the City of Bakersfield Building Department.
A summary of the tasks to be completed for the removal of the sumps is presented below.
1,0 Sump Removal
1.'1 Removal Activities
The location of the steam cleaner sump is shown on Figure 2. Prior to commencement of field
activities for removal of the sumps, permits will be prepared for submittal to the appropriate
regulatory agency.
Removal activities will be conducted in accordance with the permit conditions and Health and
Safety Plan (HASP) and work plan prepared by ENSR and ENSR's subcontractors.
The location of sumps will be identified and the sump's contents will be removed and disposed
of properly. The material in the steam clea,~er sump has been characterized as hazardous and
it is anticipated that the contents of the drilling sumps will be disposed of as non-hazardous
waste. It has been estimated by other consultants that approximately 7.5 tons of Sludge are
present in the steam cleaner sump, that 300 tons of materials are present in each of the two
small drilling sumps and approximately 750 tons of materials are present in the large drilling
sump.
The sumps will then be pressure washed and the rinsate and sumps removed for proper
disposal. It is anticipated that the rinsate from the steam cleaner sump will be characterized as
hazardous waste and the rinsate from the drilling sumps will be characterized as hazardous
waste.
It is anticipated that 10 to 20 tons of soil will be removed from beneath the steam cleaner sump.
In addition, approximately 10 tons of concrete will be removed from the steam cleaner sump for
off site disposal or recycling. No soil samples have been collected from the areas of the drilling
sumps; however, we anticipate that up to 75 tons of concrete and 25 to 50 tons of impacted soil
(non-hazardous) will be removed in conjunction with the large drilling sump and up to 40 tons of

2.0 Decontamination Procedures
All equipment used during on-site work that might come into contact with potential chemicals of
concern (COCs) will be thoroughly cleaned before and after each use. This will be
accomplished through steam cleaning and/or washing/decontamination as noted below. All
rinseate will be managed and disposed of properly.
Decontamination will include the following steps:
· Disassemble equipment;
· Wash with non-phosphate detergent (Alconox) and tap water;
· Rinse with tap water;
· Rinse with isopropyl alocohol (using a squirt bottle);
· Rinse with deionized or distilled water (triple); and
· Rinse with certified organic-free, metal-free water.
3.0 Instrument Calibration Procedures
During site activities, field data will be collected using field instruments to assess worker
exposure to volatile COCs and field screen soil samples. The protocols for field personnel,
described below, are designed so that field measurements, if made by different individuals, are
consistent and reproducible. Standard equipment calibration procedures for each instrument
are also described.
3.1 Portable Air Monitoring Equipment Calibration
A hand-held portable photo-ionization detector (PID) instrument (such as a Photovac MicroTip)
or a handheld portable flame-ionization (FID) instrument (such as a Foxboro GC128 OVA) will
be used in the field to monitor worker exposure and possibly field-screen soil samples. The PID
instrument or the FID instrument will be used to evaluate volatile organic compounds in soil and

ambient air. The~PID instrument is more responsive to volatile compounds with saturated
chemical bonds (i.e., benzene, toluene) in the part per million (ppm) concentration range while
the FID is responsive to volatile/nonvolatile compounds with carbon-hydrogen bonds (i.e.,
methane, trichloroethane, as well as benzene and toluene) in the ppm range.
Calibration of the PID instrument will be performed using the manufacturer-recommended
calibration standard span gas to adjust the span and ambient air for zero calibration.
Calibration of the FID instrument will be performed, as specified by the manufacturer, using
ambient air for zero calibration only. Calibration with a span gas, according to the
manufacturer, is not required for instrument use. Calibration of the PID and FID will be
performed before each day's sampling and at intervals throughout the day (approximately every
hour) when irregularities in the readings become apparent.

REMOVAL OF FLOOR DRAINS
The site vicinity is shown on Figure 1 and the site plan is shown on Figure 2 of the Removal
Action Workplan prepared for the site by ENSR International. Two floor drains containing
sludge are present inside the building formerly occupied by Maaco Auto Paint on the Rosedale
Hotel/Maaco parcel. The sludge in these drains and the drains, if necessary, will be removed in
accordance with applicable regulations.
ENSR estimates approximately 1 ton of sludge will be removed from the floor drains in the
Maaco building and disposed of as hazardous waste. No soil samples have been collected
from beneath the floor drains; however, we anticipate that 10 to 20 tons of soil will be removed
from beneath the floor drains. In addition, approximately 20 tons of concrete will be removed
for off site disposal or recycling.
A summary of the tasks to be completed for the removal of the sludge and floor drains is
presented below.
1.0 Removal of Floor Drains
1.1 Removal Activities
The location of the floor drains are shown on Figure 2. Prior to commencement of field activities
for removal of the sludge and drains, permits will be prepared for submittal to the appropriate
regulatory agency.
Removal activities will be conducted in accordance with the permit conditions and Health and
Safety Plan (HASP) and work plan prepared by ENSR and ENSR's subcontractors.
The location of floor drains will be identified and the contents of the drains will be removed and
disposed of properly (this material has been characterized as hazardous). It has been
estimated by other consultants that a total of approximately 1 ton of sludge is present in the two
drains. The drains will then be pressure washed and the rinsate removed for proper disposal.
If no evidence of cracking is observed inside the drains or along the drain lines, the drains will
be left in place for removal during demolition of the building. If cracks are noted, then the
drains and surrounding concrete will be removed for proper disposal. Removal of the drains will
result in two excavations, each measuring approximately 3 feet in depth and 5 feet in diameter.
Visibly impacted soils, if any, present beneath the drains will be stockpiled on-site and removed
for proper disposal after receipt and review of analytical results.
1.2 Soil Sampling
Following removal of the impacted soil, if any, soil samples will be collected from the excavation
floor and sidewalls using hand sampling equipment and, if any excavations go greater than four

feet bgs, samples will be taken from the backhoe bucket. We anticipate that up to five samples
will be collected as confirmation samples from each excavation and that one four composite will
be collected from each stockpile.
Following collection of the samples, the ends of the tube will be covered with a TeflonTM sheet,
capped, labeled, and preserved on ice for transport to the laboratory. Chain-of-custody
procedures will be followed in all phases of sample handling.
1.3 Sample Handling
Each sample will be packaged and transported appropriately, according to the following
protocol:
· Collect samples in appropriately sized and prepared containers;
· Attach completed sample label to each sample;
· Properly seal and package sample containers;
· Complete chain-of-custody/analysis request forms;
· Separate and place samples into chilled coolers for shipment to the appropriate laboratory
(samples will be packaged so the potential for shipping damage is minimized);
· Seal the top two copies of the chain-of-custody form inside a zip-lock bag and place inside
the cooler;
· Seal the cooler with several strips of strapping tape; and
· Arrange for appropriate shipment to the analytical laboratory.

Action Workplan prepared for the site by ENSR International. Four water supply wells are located
on the project site, as noted below:
Parcel Well No. Depth Diameter
(feet) (inches)
Sparks 1 60 16
Sparks 2 140 6
Seaton 3 280 8
Glen Rose 4 280 8
These wells will be destroyed as detailed below.
1.0 Water Supply Well Destruction
The locations of the four water supply wells that will be destroyed are shown on Figure 2. Prior
to commencement of field activities, ENSR will obtain well destruction permits from the Kern
County Environmental Health and Safety Department (KCEHSD).
The concrete encased protective cover boxes will be removed and, if possible, the well casings
and annular space materials will be drilled out to the total well depth. The borings will then be
backfilled with neat cement grout installed via a tremie pipe. If ENSR is unable to remove the
well casings and annular space materials, the KCESHD will be contacted for alternative means
of destruction. It is anticipated that alternative means would include perforating the casing,
removing the upper five feet of casing and pressure grouting the well to within five feet of the
ground surface. The upper five feet would be filled with native soil.
2.0 Decontamination Procedures
All equipment used during on-site work that might come into contact with potential chemicals of
concern (COCs) will be thoroughly cleaned before and after each use. This will be
accomplished through steam cleaning and/or washing with Alconox (a laboratory-grade
detergent) and rinsing with deionized, distilled or fresh water. All rinseate will be managed and
disposed of properly.

disconnect electrical service. Contractor shall be responsible for knowing how and where
emergency shut off valves for water, gas, and electrical utilities are located.
The local exhaust (HEPA filtered) system shall be equipped with a pressure regulator/warning
device that allows continuous monitoring of system operation to preclude exposure of adjacent
unsealed area to asbestos fiber concentrations in excess of 0.01 fibers/cc of air. The pressure
differential shall be maintained above 0.02 inches of water relative to pressure outside the
enclosure. Any malfunction of the local exhaust system shall be reported to the on-site
Competent Person and shall be cause for cessation of asbestos abatement until the cause is
discovered and remedied. The Consultant will be notified immediately.
4.2 REGULATED AREA--ENCLOSED
Seal openings in areas where the release of airborne asbestos fibers is expected. Establish a
regulated area with the use of curtains, portable partitions, or other enclosures to prevent the
escape of asbestos fibers from the contaminated regulated area. Provide observation
window(s) that allow a view of the entire containment area. In all possible instances, control
area development shall include protective covering of walls and ceilings with a continuous
membrane of one layer of minimum 6-mil fire retardant poly sheeting (for floors and walls) and
4-mil fire retardant poly sheeting (for ceilings ) sealed with tape to prevent water or other
damage. Provide two layers of 6-mil poly sheet over floors and extend layers a minimum of 12
inches up the walls. Seal all joints with tape. Provide a local exhaust system in the regulated
area. Veiwports shall be constructed in accordance with regional and local regulations.
Openings will be allowed in enclosures of regulated areas for the supply and exhaust of air for
the local exhaust system. Exhaust the negative air machines to the outside of the building.
Notify the Consultant if unable to exhaust in this manner. Replace filters as required to
maintain the efficiency of the system. Cleaning of items that must remain in the work area shall
be done using HEPA filtered vacuuming devices and then covered with 6-mil poly sheeting.
Mini-enclosures shall follow the above guidelines and that which is the standard of practice for
these negative pressure containment areas. Mini-enclosures may be constructed to be used in
a mobile fashion. Mini-enclosures may be constructed with 6-mil poly sheeting.
4.3 Regulated Area--Open
In certain circumstances, where establishment of a closed regulated area is not possible, and
only .after Consultant approval, an open (regulated) area may be considered. The Consultant
will be notified if the' Contractor determines that the most appropriate abatement of certain
materials would incorporate the use of an open regulated area. In no event shall the use of an
open regulated area be conflict with applicable federal, state, regional, or local regulations,
unless a waiver of the specific activity proposed is provided by the appropriate regulatory
agency. A NPES will not be utilized for the removal of non-friable roofing materials for the
buildings included in this scope of work.

Establish designated limits for the asbestos work area and barricade the designated area from
non-asbestos workers with the use of rope, caution tape or other continuous barriers. Maintain
all other requirements associated with removal and disposal of asbestos as applicable. Also,
where an enclosure is not provided, area monitoring of airborne asbestos fibers will be taken
during the work shift at the designated limits of the asbestos work area at such frequency as
specified herein.
If the quantity of airborne asbestos fibers monitored at the designated limits at any time reaches
the (time weighted average) maximum allowed in these specifications, stop work immediately.
Notify key personnel and proceed with clean-up activities. If adjacent areas are contaminated,
clean the contaminated areas, monitor and visually inspect the area as specified herein.
Decontamination procedures shall not include HEPA filtered vacuuming of workers in lieu of a
shower room. HEPA filtered vacuuming and double-suiting is allowed if a remote shower facility
must be utilized. All workers shall remove protective clothing and wash all exposed pads of
their person before leaving the area. Eating, smoking, drinking or other activities are prohibited
since these activities may potentially result in exposure to asbestos fibers. Showers, wash
basins or buckets shall be provided with towels to clean respirators daily. The Contractor shall
ensure that the workers take proper care of their assigned respirators and safety equipment.
4.4 DECONTAMINATION
Provide a decontamination room to provide a storage area for workers clothes that are used in
the negative-pressure enclosure. A separate air-lock room can be constructed for larger
equipment and waste bags; however,' use of this room still requires proper decontamination
procedures. Ingress or egress from the negative pressure enclosure area through the
equipment air-lock room shall not be used by personnel at any time. The industry standard
three stage decontamination chamber shall be constructed for all negative pressure
enclosure areas for this project, including but not limited to areas of floor tile and mastic
removal.
A remote decontamination unit may be used for workers involved in glovebag or mini-enclosure
operations. Remote units must be placed Within the regulated area where unauthorized
personnel will not cross the path from the work area to the remote unit. Consultant reserves
the right to approve use and placement of remote units for asbestos abatement.
4.5 ACCESS TO WORK AREA
The Asbestos Abatement Contractor shall make available to the Consultant any personal
protective equipment (not including respirators unless supplied air respirators are required) as
required herein for entry to the regulated area at all times for observation of the regulated area.
Access to the work area shall be regulated as follows:
Access To Isolated Work Areas by Others: Except for an emergency and the Contractor's
authorized personnel, the Contractor shall limit access to the work area to authorized

representatives of the Consultant. At no time shall any personnel enter an enclosure without
notifying the on-site Competent Person first and signing the site entry log.
Visitor Communications: All inquiries concerning the work site, asbestos abatement project and
other job activities shall be directed to the on-site Competent Person. The Contractor shall
notify the Consultant of visitors (i.e. regulatory inspectors, OSHA personnel, law enforcement,
fire department personnel, press, etc.) that visit the site during the project. If the Contractor is
cited by a regulatory agency, the Contractor shall immediately notify the Owner and Consultant.
Audio-Visual Surveillance: The contractor shall provide an observation window (in accordance
with applicable regulations) for enclosures so that the supervisor can monitor work activity. In
areas where visual access is not possible, the Consultant may require headsets or walkie-
talkies for audio communications.
4.6 AIR MONITORING
Monitoring of airborne concentrations of asbestos fibers shall be in accordance with the
specified regulations, Section 2.4 of this docUment, and as specified hereafter (29 CFR
1926.1101 (f)). An initial exposure assessment shall be performed for each area unless
previously sampled or in areas shown not to present concentrations exceeding the PEL under
the given work conditions.
Periodic monitoring is required outside the negative pressure enclosure or adjacent to the
glovebag operation (area air monitoring). Clearance air monitoring is required after clean-up
and encapsulation ("Lock Down") and the employer must demonstrate the airborne
concentration are below the EPA Clearance Criteria for PCM or TEM.
4.6.1 Review
Personnel and procedures utilized by the Contractor are subject to review. Area and' personal
air monitoring shall be performed by the Contractor's CIH.
4.6.2 Records
Documentation shall be kept for each filter sample procured as to worker sampled, respiratory
protection equipment used, work area location, date and time taken, volume of air drawn
through filter, pump identification number and calibration. Documentation shall indicate whether
tests were taken in isolated work areas, in glovebag work areas, in occupied public spaces,
etc., and shall be part of the permanent record provided at project completion.
4.6.3 Air Samples
The following refers to the different type of air samples:

Area Air Sampling: Area air samples shall be collected by the Contractor's CIH to evaluate the
integrity of the containment structure. Area air samples for glovebag operations shall be
conducted at 10% of the locations abated. The sampling protocol shall conform to the NIOSH
582 standards and 40 CFR Part 763.
Personal Air Samples: The Contractor is responsible for monitoring its employees' exposure
and maintaining the proper records (29 CFR 1926.1101 and' 1910.1001 ).
Results of all area air monitoring shall be made available to the Consultant within 48
hours of sampling. Results of all personal air monitoring shall be made available to the
Consultant within one week of the completion of the project, unless, as stated in 36.4.2, the
PEL is exceeded.
If the results of PCM analysis exceed the established limits, the Contractor will be required to
initiate additional air and surface cleaning procedures, as instructed by the Consultant to reduce
fiber concentration below these limits. Contractor shall notify Consultant immediately by phone
and fax if the PEL is exceeded. The Contractor may resume abatement work in that area only
after he receives authorization from the Consultant. Any costs resulting from high air sampling
results above the regulatory criteria shall be borne by the Contractor and will not be a basis for
an increase in the contract amount.
The Consultant will collect "clearance" air samples at the conclusion of the asbestos abatement
activities for each of the containment areas for this project. For those areas where friable
asbestos materials will be removed, the air samples will be analyzed by TEM AHERA.
PCM analysis will be used for those areas where only non-friable materials will be
removed. The number and placement of samples will be determined by the Consultant. If the
results of air sample cassette analysis indicate the Contractor failed final clearance by PCM
analysis, the air sample cassettes that failed by PCM analysis will be subsequently analyzed by
TEM AHERA. If air sample cassettes fail clearance criteria by TEM AHERA analysis, the
Consultant will require the Contractor to reclean the containment area prior to resampling. This
activity shall be performed by the Contractor and shall not be cause for change order.
Costs associated with additional TEM AHERA analysis and resampling due to failed clearance
samples will be the responsibility of the Contractor, and will not be cause for a change order. In
addition, it is not anticipated at this time that active demolition work will occur for the buildings
until all asbestos abatement activities are completed. If, at a later date, it is established that
active demolition work will occur in conjunction with asbestos abatement activities to expedite
the project schedule, TEM analysis may need to be used for all air samples collected.
4.7 ASBESTOS HANDLING PROCEDURES DURING REMOVAL
General Procedures: Follow procedures described in Sections 4.1 through 4.7. Sufficiently wet
asbestos material with a fine spray of amended water during removal, cutting, or other handling
to reduce the emission of airborne fibers. Remove material and immediately place in poly

disposal bags. Where unusual circumstances prohibit the use of poly bags, submit an alternate
proposal for containment of asbestos fibers to the Consultant for approval. Contractor shall
properly notify their employees of the ACM content and train them in the standard of practice
procedures for removal of the ACMs in accordance with federal, state, and local regulations.
Reference 29 CFR 1926.1101 (g), Methods of Compliance.
Cleaning objects prior to abatement: All moveable objects must be HEPA vacuumed and wet
wiped prior to scheduled removal and prior to abatement cleaning, temporary storage and
relocation must be conducted according to Consultant instructions. All immovable objects must
be pre-cleaned by HEPA vacuum and wet-wiping. Fixed building materials that may be
damaged by wet wiping shall be HEPA vacuumed only.
Sealing and Removal of Asbestos Contaminated Items for Disposal: Remove any remaining
contaminated architectural, mechanical, and electrical appurtenances such as venetian blinds,
full-height partitions, carpeting, duct work, pipes and fittings, radiators, light fixtures, conduit,
panels, and other contaminated items designated for removal by first, HEPA vacuuming, and
then, completely coating the items with an asbestos sealer at the demolition site before
removing the items from the regulated area. The asbestos sealer shall be tinted a contrasting
color. It shall be spray-applied by the airless method. Thoroughness of the sealing operation
shall be visually gauged by the extent of colored coating on exposed surfaces.
Abatement methods for various types of asbestos containing materials are described below:
Category II ("cementitious'~ Non-friable ACM: Where troweled on ceilings, "TransiteTM'' panels
or pipes, are rigid and removal may involve breaki-ng, cutting and damaging the material so that
fibers are released, the Contractor shall remove this material under full containment, negative
air pressure, wet removal techniques and with personnel using safety equipment for head, eyes
and ears as specified. Alternative procedures must be cleared by the Consultant before
removal. The rigid ACM can be cut and broken into smaller pieces for ease of handling utilizing
appropriate work practices, although breaking these materials should be minimized as much as
practical so as to minimize the potential for releasing airborne asbestos fibers. Work practices
that create dust or otherwise release airborne asbestos fibers shall be avoided.
Asphalt Roofing Mater/ah Built-up roofing, asphalt impregnated felt and roofing mastics must
be removed and disposed using wet methods and other dust control measures necessary to
comply with federal, state, and local regulations. The Contractor must still monitor and notify
the employees of the asbestos content of the materials to be abated. Where powered tools are
used for removal, local HEPA vacuuming must be used.
Flooring: Vinyl floor tiles (VFT) and sheet vinyl flooring must be removed under full containment
using negative air pressure, wet removal techniques and with personnel using safety equipment
for head, eyes and ears as specified. If all the floor tiles within the work area can be removed
intact, without breakage, then the removal will not require negative pressure enclosure. The
Consultant shall approve such work before it commences. Asbestos containing backing

materials are considered friable, in most cases, for disposal purposes. Asbestos containing
mastic shall be removed from the substrate using industry standard methods. A mini-
containment may be used for removing small areas of flooring, such as a 3x3 foot area. Note
that mastic removal chemicals may require special respiratory protection and, thus, this
protection must be implemented along with the proper notification and training. Regional and
local regulatory agency regulations that restrict the use of mastic removal chemicals
and/or bead blasting equipment shall be obeyed.
Mastics: If mastic is considered non-friable by the Consultant, and the mastic can be removed
intact (without cutting, abrading, breaking, etc.), then the mastic may be removed without
containment using amended water. The removed mastic must be immediately bagged.
However, the Contractor must still establish the regulated area to keep unauthorized personnel
from the area. The Contractor will still conduct the work with the proper personal protective
equipment and respiratory protection.
If the mastic must be removed using chemicals and/or mechanical devices, then the material
must be removed as described in the previous paragraph. The Consultant will be notified if
mechanical bead blasting will be used for the removal of the mastic, Federal, state,
regional and local regulatory agency regulations that restrict the use of mechanical bead
blasting equipment and that indicate appropriate containment for these activities shall be
obeyed. In the event that the use of unauthorized bead blasting equipment, abatement
methods, or containments results in a notice of violation issued by a regulatory agency, the
contractor shall be responsible for costs associated with the payment of the fine, and other legal
costs that may arise as a result of the notice of violation. These costs are not to be cause for a
change order. It is assumed that the Contractors submitting bids for the abatement of materials
included in these specifications are knowledgeable and proficient in regulations applicable to
their industry.
Insulated Wiring: Contractor shall coordinate with building engineer to ensure that the wiring to
be removed and nearby wiring has been deenergized and tagged out. Disconnect each end of
the wiring so that the wiring may be pulled through the conduit and properly bagged. Water
shall not be used until a section of wiring is completely removed and placed in the disposal bag.
Surfacing and Miscellaneous Friable Materials: These materials must be abated under
containment and disposed using wet methods and other dust control measures necessary to
comply with federal, state, and local regulations. The Contractor must monitor and notify the
employees of the asbestos content of the materials to be abated.
Friable Sprayed Acoustic Ceiling and Fireproofing Materials: These materials must be abated
under full containment. Poly sheeting must be attached to the wall at the point closest to the
ceiling. Use a fine spray or mist of amended water to thoroughly saturate the material. The wet
material should then be removed and bagged immediately. After removal, the substrate must
be cleaned ~using brushes, wet-wiping, and HEPA vacuum, until all asbestos residue is gone.
The substrate should then be sprayed with an encapsulant. The sprayed acoustic ceilings shall

be scraped of the material and immediately placed in the disposal bags. In addition to the items
mentioned in the previous paragraph, the Consultant requires that local HEPA exhaust be used
at the point of actual removal along with the dedicated negative air machines. Neither shall be
used in lieu of the other.
Drywall/Joint Compounds/Waft Texture: Wall systems where the asbestos content is greater
than 0.1% or classified as friable shall be removed under full containment and disposed using
wet methods and other dust control measures necessary to comply with applicable federal,
state, regional, and local regulations. Please note that joint compound may be considered
non-friable for notification purposes but will be considered friable for abatement
purposes. Wet methods shall be used for dust suppression. The Contractor is responsible for
notifying their employees. For those areas where the sheetrock wall systems contain "Trace"
amounts of asbestos (less than 1%), and no texture, skim coat, or spray-applied ceiling
materials are present on the wall, the sheetrock wall systems do not have to be removed under
full containment. These materials can be discarded as non-ACM waste. However, the handling
of these materials shall not be in violation of "visible emissions" provisions within applicable
regulations.
Ceiling Tiles/Mastic: These materials must be abated under full containment. Poly sheeting
must be attached to the wall at the point closest to the ceiling. If there are openings above the
ceiling, these openings must be sealed prior to abatement. The ceiling tiles shall be removed
intact as much as possible and immediately placed in the disposal bags. Small amounts of
ACM may be removed using a negative pressure mini-containment structure that is attached to
the surrounding ceiling tiles. An example of a removal area for a mini-containment is 3x3 feet.
If mastic alone contains asbestos and is considered non-friable by the Consultant, then removal
can be completed wit.hout containment as long as the mastic 'blob' is removed intact as
described in "mastics" paragraph, above. The ceiling tile and mastic shall be properly bagged
and disposed.
Thermal System Insulation (TSI) - Friable Materials: These materials must be abated and
disposed using wet methods and other dust control measures necessary to comply with federal,
state, and local regulations. Contractor shall remove this material under full containment,
negative air pressure, wet removal techniques and with personnel using safety equipment for
head, eyes and ears as specified. Alternative procedures must be cleared by the Consultant
before removal. The rigid ACM can be cut and broken into smaller pieces for ease of handling
utilizing appropriate work practices. Creating dust shall be avoided.
TS/- Pipe Insulation: TSI may also be removed using proper glovebag procedures. Glovebags
may not be moved or slid along a pipe run. A smoke test may be performed on every other
installed glovebag to check for air leaks. The bare pipe shall be detail cleaned and
encapsulated after the asbestos insulation is removed.
Pipe insulation may be removed by using a wrap and cut method of removal, if approved by the
Owner. Apply amended water and double wrap the pipe to be cut and removed with 6-mil poly

sheeting and sealed with duct tape and spray adhesive. Use usual glovebag procedure on
either end where the pipe will be cut, usually in 8 to 10 foot lengths. The sealed bag shall be
properly labeled.
Isolation Fabric on Ducting: This material shall be removed under full containment; however, if
feasible, a mini-containment can be constructed to remove the material. In either case,
negative pressure shall be used and the ducting shall have a critical seal. The furnace or
blower shall be shut down and tagged out. Coordinate this procedure with the building
engineer. Amended water shall be applied to the fabric before work is commenced. This
friable material shall be removed intact by dismantling the material from the duct or cutting the
sheet metal as close to the edge of fabric as feasible. The material shall be immediately
bagged. Once the ACM is removed, the remaining ducting within the containment area shall be
HEPA vacuumed and wet-wiped. The ducting shall be spray encapsulated; however, if the
furnace or blower is to be reused, then the Contractor shall not encapsulate the equipment.
Concrete Rubble Pile: A former concrete parking structure was demolished in the mid-1990s.
At the current time, a large pile of concrete rubble generated during this demolition is located on
the northwestern portion of the site. Reportedly, a survey report was prepared for the building
in the 1980s; however, a copy of this report was not available to the Consultant. Our
observations of rubble pile did not indicate the presence of mastic or other materials that may
contain asbestos; however, any pieces of rubble noted to contain mastics or other suspect
building materials should be placed in a separate pile and tested for asbestos. Concrete rubble
with asbestos containing materials should be removed from the site for proper disposal. It may
be possible to dispose of this material as general demolition debris if acceptable to the disposal
facility. /
4.8 DISPOSAL
The Contractor shall determine current waste handling, transportation, and disposal regulations
for the work site and for each waste disposal landfill. The Contractor must comply fully with
these regulations and all DOT and EPA requirements. Material will be delivered directly to the
pre-designated disposal site within five days for burial. All labels and signs shall be in
accordance with EPA, OSHA, and DOT regulations as described in Sections 3.8 and 3.9. The
Contractor shall fill out manifest forms for the Owner's (Generator) signature. Original disposal
receipts and manifests must be turned in at project completion to the Owner. Copies shall be
forwarded to the Consultant.
Containers: Sealed containers may be stored in the bag holding and decontamination
enclosure system until a sufficient volume of waste has accumulated for disposal but not to
exceed five days. This storage area will be prominently designated and waste containers will
be covered with polyethylene sheeting. Waste should be stored out of sight of the public in a
secure area.

area and work site at the end of each work day. Workers unloading the sealed bags and
machinery operators will wear respirators when handling material at the disposal site and shall
be a state certified asbestos worker.
Disposal Site: The disposal site chosen for friable materials shall be permitted to receive this
type of waste. Non-friable materials may be disposed as non-hazardous construction waste at
a disposal site permitted to receive the waste. The Contractor shall notify the receiving non-
hazardous waste landfill of the type and nature of the asbestos debris to be disposed.
4.9 GENERAL PROCEDURES
The Contractor shall implement procedures that comply with or exceed federal, state, and local
regulations. The procedures, while not specifically described here, shall be protective of
employees, site occupants, other contractors, and site improvements and equipment.
Coordinate all electrical and water service connections with the Owner. The Contractor shall be
responsible for ensuring that air handling systems in the work area are isolated and shut down
for the duration on the project. The Contractor shall coordinate with the Owner with respect to
site security, emergency shut off of water, and building fire suppression systems. The
Contractor shall not violate the fire code as it relates to the site building.
Setup, abatement, disposal, and demobilization shall be performed so that ACMs RACMS, and
ACCMs are not disturbed unless they are in a negative pressure containment in the process of
being abated. Setup procedures may require the use of respirators with P100 filters or HEPA
filtered air purifying negative pressure fans, critical barriers, and decontamination facilities.
The use of drugs, alcohol, or prescription medication that may impair judgment or otherwise
compromise the safety of workers or any persons on the site is strictly prohibited. Smoking is
not allowed in the jobsite buildings.

be of 99.97% efficiency for retaining fibers of 0.3 microns or larger.
P100 Filter: A high efficiency particulate air filter (formerly known as a HEPA filter, currently
known as a P100 filter) capable of trapping and retaining 99.97 percent of mono-dispersed
particles greater than 0.3 microns in diameter.
Permissible Exposure Limit (PEL): The airborne concentration of asbestos (0.1 fibers/cc) at
which the employer shall ensure that no employee is exposed. Where the PEL is exceeded the
employer shall establish and implement a written program to reduce employee exposure to or
below the limit by (1) engineering and work practice controls, and (2) use of required proper
respiratory protection. No employee shall be exposed at any time to airborne concentrations of
asbestos in excess of 1.0 fibers/cc during any 30 minute period, which is the excursion limit.
Personal Monitoring: Air monitoring for asbestos fiber concentrations within the breathing
zone (within 9 inches of the mouth) of an employee.
Pressure Differential and Ventilation System: A local exhaust system, utilizing P100 (HEPA)
filtration capable of maintaining a pressure differential with the inside of the Work Area at a
lower pressure than any adjacent area, and which cleans recirculated air or generates a
constant air flow from adjacent areas into the Work Area.
Protection Factor: The ratio of the ambient concentration of an airborne substance to the
concentration of the substance inside the respirator at the breathing zone of the wearer. The
protection factor is a measure of the degree of protection provided by a respirator to the wearer.
Regulated Area: An area established by the Contractor to demarcate areas where Class I, II,
and III asbestos work is conducted, and any adjoining area where debris and waste from such
asbestos work accumulate; and a work area within which airborne concentrations of asbestos,
exceed or there is a reasonable possibility they may exceed the PEL. Requirements for
regulated areas are set out in 29 CFR 1926.1101 (e).

Removal: The taking ~ut or stripping of asbestos.
Repair: Returning damaged ACM to an undamaged condition or to an intact state so as to
prevent fiber release.
Respirator: A device designed to protect the wearer from the inhalation of harmful
atmospheres.
Shower Room: A room between the clean room and the equipment room in the worker
decontamination enclosure system, with hot and cold or warm running water and arranged for
complete showering during decontamination. The shower room may comprise an airlock
between contaminated and clean areas.
Surfacing Material: Material that is sprayed, troweled-on or otherwise applied to surfaces
(such as acoustical plaster on ceilings and fireproofing materials on structural members, or
other materials on surfaces for acoustical, fireproofing, and other purposes. Surfacing ACM is
surfacing material which contains more than 1% asbestos,
Surfactant: A chemical wetting agent added to water to improve penetration, thus reducing the
quantity of water required for a given operation or area.
Tack Coat: A coat of penetrating encapsulant applied to all surfaces from which ACM has
been removed.
Thermal System Insulation (TSI): ACM applied to pipes, fittings, boilers breaching, tanks,
ducts or other structural components to prevent heat loss or gain.
Time Weighted Average (TWA): One or more samples representing full shift exposure for an
employee in each work area. Samples should be averaged over an eight hour work day.
Visible Emissions: Any emissions containing particulate asbestos material that are visually
detectable without the aid of instruments. This does not include condensed uncombined water
vapor.
Wet Cleaning: The process of eliminating asbestos contamination from building surfaces and
objects by using cloths, mops, or other cleaning utensils which have been dampened with
amended water or diluted removal encapsulant and afterwards thoroughly decontaminated or
disposed of as asbestos-contaminated waste.
Wetting Agents: Amended water (surfactant) is used for all asbestos removal and disposal
activities. Airless sprayers are used to apply amended water during removal procedures.
Elimination of asbestos from building or equipment surfaces is by wetted cloths, mops and
other cleaning tools.

Work Area: The area where asbestos-related work or removal operations are performed which
is defined and/or isolated to prevent the spread of asbestos dust, fibers or debris, and entry by
unauthorized personnel. Work area is a Regulated Area as defined by 29 CFR 1926.
Work Hygiene Facilities: A decontamination system for workers, equipment and clothing. It
consists of a clean room; shower room and decontamination room and. is normally contiguous
with an enclosure.
Wrap and Cut: Removal of TSI by first double wrapping insulated pipe section with 6-mil poly
sheeting and sealing both ends. The pipe section can then be cut at either end and then
removed. The wrapped waste must be properly labeled.
