' 2.2.1 Phase II Environmental Site Assessment: Soils En in
eering„ Inc.;July 2003
Soils Engineering, Inc. (SEI) prepared a report in July 2003 for a Phase II Environmental Site
' Assessment (Phase II) that was conducted at the subject property. The scope of the Phase II
included a total of four hand-augered soil borings advanced throughout the subject property.
' Please see Figure 3 for a map indicating previous soil boring locations.
Each boring was advanced to a terminal depth of 5 feet below ground surface (bgs) with soil
' samples collected at 1, 3, and 5 feet bgs. Each sample was analyzed for volatile organic
compounds (VOCs) via Environmental Protection Agency (EPA) Method 8260B. Please see
Table 2.2.1-1 for a summary of the Phase II soil sample laboratory results.

Tetrachloroethene (PCE) was detected in 11 of the samples at concentrations ranging from 35 to
D 800 micrograms per kilogram (µg/Kg). No other VOCs were detected in any of the analyzed
soil samples.
OBased on the results of the investigation, SEI concluded that PCE was restricted to the upper 2
feet of soil and estimated that the volume of soil with PCE concentrations exceeding 100 µg/Kg
was at least 17 cubic yards. SEI determined that the lateral extent of the soil PCE plume was not
Destablished, but had a minimum radius of 3 feet.
D SEI concluded that the risk of the detected on-site release to the environment and human health
was acceptable. SEI recommended installing secondary containment beneath the DCM and
hazardous materials storage areas and resealing the floor in the vicinity of the DCM to prevent
future releases to the subsurface.
2.2.2 Phase I Environmental Site Assessment:AEI:July 2006
DAccording to a Phase I Environmental Site Assessment (Phase I) Report prepared by AEI in July
2006, a dry cleaning facility has occupied the subject property since 1986. During the Phase I
Dsite reconnaissance, no secondary containment was noted beneath the DCM.
The Phase I included a review of the SEI July 2003 Phase II. The Phase I concluded that the
D release should be reported to the lead regulatory agency and the site should be brought to case
closure status, which may involve additional soil sampling and/or remediation.
2.2.3 Additional Soil Characterization:AEI:August 2006
In August 2006, AEI conducted Additional Soil Characterization (ASC) in the vicinity of the dry
D cleaning facility. The scope of the ASC included a total of six soil borings (AEI-B5 through
AEI-B 10) advanced to terminal depths of 20 and 25 feet below ground surface (bgs). PCE was
detected in 12 of the analyzed soil samples at concentrations ranging from 1.2 to 307 µg/Kg.

The PCE release previously detected during the SEI Phase 11 was reasonably well characterized
laterally and vertically during this investigation. PCE concentrations generally decreased to just
0 above the laboratory detection limit or to non-detectable levels with increasing vertical depth and
lateral distance from the DCM. The maximum radius of the soil PCE plume appeared to be
approximately 75 feet from the apparent on-site release point, though elevated PCE
concentrations were only generally detected in shallow soil (less than 5 feet bgs) in the
immediate vicinity of the DCM. Please see Figure 2.2-1 for a map of PCE concentrations
detected during both investigations. Please see Figure 2.2-2 for peak PCE isoconcentrations in
shallow soil.
0 Two analyzed soil samples exceeded the residential soil PRG for PCE. Both samples were
collected during the previous SEI investigation. Four analyzed soil samples exceeded the site-
specific SSL for PCE. All samples that exceeded available regulatory guidelines and/or action
levels were collected at shallow depths (2 feet bgs and shallower).
The bulk of PCE in the subsurface appeared to be retained within the predominantly silty upper 5
feet of soil beneath the dry cleaning facility in the immediate vicinity of the DCM. AEI
recommended remediating shallow PCE-impacted soil in the vicinity of the DCM to reduce
source contamination beneath the subject property.

2.3 Hyd rogeologic Conditions
a2.3.1 Local/Site Geolo�y
aBased on a review of the United States Geological Survey (USGS) Gosford Quadrangle
Topographic Map,'the subject property is situated 371 feet above mean sea level (amsl) and the
local topography is sloping to the southeast.
a
According o information provided on the Natural Resources Conservation Service NRCS
g P ( )
website, the area surrounding the subject property is underlain by soils of the Kimberlina-Urban
OLand-Cajon Complex. These soils are characterized by a mixture of coarse loam, which consists
of mostly sand, silt, and clay. The underlying soils are characterized hydrologically as Classes A
and B (which refer to moderate infiltration rates) with well-drained soils.
a
According to information obtained from the Department of Water Resources, the area
a surrounding the subject property is a large northwesterly trending geosyncline or structural
trough between the Coast Range and the Sierra Nevada Mountains. Erosion from both of these
mountain systems has resulted in the deposition of an immense thickness of sediments in the
valley floor. The edges of the province are marked by prominent alluvial fans. The site is
underlain by Pleistocene alluvial deposits.
Based on borings advanced during the previous investigations, the subject property is underlain
O predominantly by light or yellowish brown well-graded sand (SW). Brown or olive brown silt
and sandy silt (ML) were encountered to 5 feet bgs beneath the subject property building and to
10 feet bgs beneath the parking lot.
2.3.2 Local/Site Hydrogeology
OThe nearest surface water is the Farmers Canal located approximately 0.08 mile east. Based on
topographic map interpretation, the inferred flow direction of groundwater at the subject
property is to the southeast. According to the State Water Resources Control Board (SWRCB)
GeoTracker Website, the nearest Leaking Underground Fuel Tank (LUFT) site with active
monitoring wells is located at 1701 Stine Road on the intersection of Stine Road and Ming
Avenue, which is approximately 1.4 miles north-northeast of the subject property. The LUFT
site maintains three monitoring wells, which were last measured on January 17, 2006. Depth to
groundwater ranged from 167.92 to 167.24 feet bgs. Groundwater was not encountered in any
borings advanced during the previous investigations.

3.0 SPAT ML L VARffATffON OF PCE
0 PCE was detected in soil samples collected from shallow unsaturated soils, which indicated that
a release had occurred as a result of on-site dry cleaning activities. The soil PCE plume
appeared to be localized around the DCM. Previous data fully characterized the PCE plume in
shallow unsaturated soils. The peak level of PCE in unsaturated soils throughout the previous
investigations was detected in the soil sample collected at 1 foot bgs at boring 133 with a
aconcentration of 800 µg/Kg. Please see Figure 2.2-1 for a map of PCE concentrations detected
during both investigations. Please see Figure 2.2-2 for peak PCE isoconcentrations in shallow
soil.

The environmental behavior of PCE is dependent upon the grain size and the moisture and
n organic carbon content of the soil. PCE is retained in soil with high clay and organic carbon
content. The most common breakdown products of PCE are TCE; cis-1,2-DCE; trans-1,2-DCE;
and vinyl chloride (VC). The density of PCE is approximately five times that of air, which is
1.29 grams per cubic centimeter(g/cm3). Therefore, PCE vapors tend to sink in soil and migrate
vertically downward to the water table. Liquid PCE, a dense non-aqueous phase liquid
(DNAPL), tends to sink because of its poor water solubility and high density.
5.0 CLEANUP SC ENA1 OS
It is instructive to list the various remedial options that are available to deal with the
contamination on the subject site.

5.1 Groundwater
At this point, groundwater treatment is not required. Quarterly monitoring will continue for four
events, and based upon the analytical results, no further action may be granted by the BFD.
5.2 Shallow Soils
5.2.1 Risk-Based Closure
A directive issued by the EPA in 1998 defined clean closure as a site where all hazardous wastes,
aliners, and environmental media contaminated by releases from the facility have been removed
or decontaminated. With regard to residual contamination, the directive clarified that clean
closure standards can be risk based, specified situations where fate and transport modeling are
acceptable, and allowed for the use of non-residential exposure scenarios (e.g., industrial usage
of property). Therefore, a site where a hazardous waste release has occurred may not necessarily
a require remediation. Instead, the lead regulatory agency can require that the responsible party
prove the following in order to grant the site risk-based closure:
a o The release is not dangerous to human inhabitants;
o The release does not affect any sensitive receptors (e.g., marina or marsh areas);
o The site does not degrade or pose a threat to degrade any useful groundwater resources.
Previous investigations have indicated that the on-site release has not impacted groundwater
beneath the subject property; however, the high concentrations of PCE in shallow soil could pose
a human health risk through indoor air vapor intrusion, should the site be redeveloped for
residential purposes.
(� 5.2.2 Excavation oflmpacted Soil
U Excavation and offsite disposal is an aggressive and effective method for remediating soil
a impacted by a release of PCE. However, based on previous investigations, a significant mass of
impacted soil underlies the foundations of structures currently located on-site. Therefore, the
amount of soil removal required to adequately remediate the site could potentially pose a threat
to the structural integrity of the building.
In addition, the site is currently occupied by an active dry cleaning facility. Therefore,
Dexcavation could greatly impact the current tenant's business during remediation activities.

5.2.3 In-Situ Chemical Treatment
In-situ chemical treatment.of chlorinated solvent contamination in soil and groundwater has
become more popular in the last ten years because of advances in both chemical compounds as
well as delivery systems. There are two pathways by which chlorinated solvents can degrade: an
oxidation pathway where the compounds are converted to harmless carbon dioxide, water, and
hydrochloric acid, and a reduction pathway where compounds undergo the process of
dechlorination. Reductive dechlorination converts chlorinated hydrocarbons according to the
following steps: PCE—TCE—DCE—VC—ethylene.
The oxidative pathway can be promoted by means of injection of strong oxidizers such as
Fenton's reagent (ferrous iron and hydrogen peroxide), potassium and sodium permanganate,
ozone, and ozone plus hydrogen peroxide (Perozone®). The reductive dechlorination pathway
can be stimulated by injecting proprietary materials such as hydrogen release compound
(HRC®) which scavenge dissolved oxygen from the groundwater, and create highly reducing
conditions.
AEI considered injection of potassium permanganate for treatment of shallow contaminated soils
near the DCM; however, the option was rejected because of doubts that contact between
uchemical and contaminant could be achieved, and concerns over disruption of dry cleaning
operations and possible "daylighting" of permanganate solutions inside the building.
D5.2.4 Soil Vapor Extraction
Soil vapor extraction (SVE) is a widely used, proven, and cost-effective in-situ technology that
has been employed to remove VOCs such as PCE and TCE from the unsaturated zone for
approximately the last 20 years. The system consists of wells, a vacuum pump, and an effluent
O vapor treatment device. As vapor is pumped toward the extraction well, VOCs sorbed on the
soil partition into the vapor phase. The vapors pass through canisters containing granular
activated carbon (GAC) where VOCs are removed prior to release to the atmosphere. SVE is
most effective when soil permeability falls within the range 10-6 to 10"2 cm/sec. The increased
ILI
airflow through the subsurface can also stimulate biodegradation of some of the contaminants,
especially those that are less volatile. Extraction wells may be either vertical or horizontal.

Based upon the conditions known to be present at the subject property, AEI recommends SVE
for cleanup of contaminated soils at the subject site. First, the soil is silty with conductivity to
' vapor in the 10-5 centimeters/second (cm/sec) to 10"4 cm/sec range, which is adequate for
performance of SVE. Second, SVE can be used to treat soil in the immediate vicinity of the
DCM as well as the area of the larger soil contaminant plume having a radius of—75 feet from
the release point. Given the shallow depth of the contaminated soil plume, AEI recommends that
a horizontal well be installed.
' 6.0 SCOPE OF PROPOSED REMEDIAL ACTION
1 The small contaminated soil volume and high concentrations of PCE at 1 - 2 feet bgs could be
effectively addressed by means of a single horizontal extraction well extending from the rear
parking lot to beneath the DCM. The SVE unit will be stationed in the rear parking lot and
' connected to the extraction well by aboveground piping. AEI estimates that a minimum of 6
months of SVE will be necessary to sufficiently remediate the site.
' Remediation of the subject property via SVE will generally take place in five phases:
• Preparation;
• Operation and maintenance;
' • Evaluation;
• Confirmation sampling and closure application, and
• Well decommissioning.
' The following sections will describe each phase in detail, respectively.

n6.1 Preparation
u The preparation phase consists of preparation of a Health and Safety Plan, permitting, and
equipment installation and field testing.
0 6.1.1 Health and Safety Plan
O Prior to commencement of any field activities, a site safety meeting will be held at a designated
command post near the working area. Emergency procedures will be outlined at this meeting,
including an explanation of the hazards of the known or suspected chemicals of interest. All site
Opersonnel will be in Level D personal protection equipment, which is the anticipated maximum
amount of protection needed. A working area will be established to delineate the zone where
hard hats and steel-toed shoes must be worn, and where unauthorized personnel will not be
aallowed. A site safety plan conforming to Part 1910.120 (i) (2) of 29 CFR will be on-site at all
times during the project. A photoionization detector (PID) will monitor the air quality
O continuously, and respirators will be required if the PID indicates that ambient contaminant
concentrations exceed 25 parts per million (ppm). Please see Appendix A for a Health and
Safety Plan.
61.2 Remedial Action Plan and Well Installation
O Upon approval of this workplan by the BFD, AEI will install a single horizontal extraction well
at a depth of 2 feet bgs and six soil vapor probes at 3 feet bgs.
0 In order to minimize site disruption, AEI will utilize horizontal directional drilling (HDD)
technology to install the horizontal well. HDD does not require trenching, which would be
highly intrusive. Horizontal SVE wells are constructed by drilling from surface to surface. The
a drill head is inclined downward into the soil and advanced into the ground by pushing and
rotating the drill rods. When the drill head reaches a predetermined location, the drill head is
positioned so that the drill is advanced in a horizontal direction only. The drill is advanced the
a length of the impacted soil, after which the drill head is repositioned so that the drill is advanced
towards the surface. The drill head is replaced with a reamer to enlarge the borehole and pull the
attached well materials into the borehole.
0 A shallow 4-foot by 2-foot by 2-foot deep pit will be excavated in the rear parking lot and a rig
with a steerable drill bit will be used to advance a borehole beneath the building at a depth of
O approximately 2 feet bgs. The bit will exit the ground inside the dry cleaner where a reamer will
be attached. The reamer will be pulled back through the borehole to increase the hole diameter
to accommodate pipe and screen. An appropriate length of 2 inch ID PVC pipe and textile
wrapped screen will either be pushed or pulled into the borehole, resulting in a horizontal vapor
extraction well.

Please see Figure 6.1.1-1 for the horizontal extraction well construction diagram.
6.1.3 Permitting
O AEI will secure the necessary permit to construct and operate from the South Coast Air Quality
Management District (SCAQMD) for the installation and operation of the SVE blower and
treatment system.
O6.1.4 SVE Equipment Installation and Testing
O AEI will establish electrical service, transport and install the SVE pump and GAC treatment
system, install fencing around the equipment compound, and connect the SVE pump to the
extraction well by means of above-grade piping.
DThe SVE remediation system will typically consist of the following equipment:
o Blower powered by a 5 horsepower electric motor(230 volt one-phase motor);
o Liquid knockout tank with an inlet silencer and a high level switch;
o National Electrical Manufacturers Association (NEMA) 4 rated electrical control panel
aconnected to a flow meter, a 30-amp fused disconnect switch, and a vacuum indicator;
o Two 500 pound activated carbon canisters connected in series.
The entire system will be enclosed in a fenced-compound. A power pole will be required to
provide electricity to the system. Please see Figure 6.1.3-1 for a schematic diagram of the
0 proposed SVE system, SVE well, and piping layout.
The horizontal SVE well will be connected to the blower by flexible 2" ID PVC hose. A ball
Ovalve will be installed to adjust flow to the well.
Once installed, the system will be tested to determine the relationship between applied vacuum,
O radius of influence (ROI), and PCE mass removal rate. Applied vacuum to the extraction well
will be measured with a standard pressure gauge, and suction measurements will be made in soil
vapor probes with a Magnahelix® gauge. Samples of effluent vapor to be analyzed by
0 Environmental Protection Agency (EPA) Method 8260B for volatile organic compounds (VOCs)
will be collected into Tedlar bags at the extraction well head and at soil vapor probes at several
different values of applied vacuum. A Velocicalc® flow meter will be used to measure the flow
0 rate of vapor coming from the well. Using these data, AEI will determine the optimum applied
vacuum, radius of influence of the horizontal well, and mass removal rate for PCE.

6.2 Operation and Maintenance
Once the SVE system is installed and operational, AEI will conduct weekly inspections for six
months, which will entail measuring flow rate and collecting soil vapor samples from the
extraction well and effluent from the GAC treatment system. The samples will be analyzed for
VOCs. Periodic maintenance of the SVE pump such as oil and filter changes, and replenishment
of the GAC will be conducted as required.
OSoil vapor samples will be collected from the knockout tank and from the outlet of the first
activated carbon canister as dictated by the discharge permit to remain in compliance as well as
O on a weekly basis to determine when breakthrough of the first carbon canister occurs. When
breakthrough occurs, the second carbon canister will be promoted to the first position and a new
carbon canister will be installed for redundancy. The activated carbon usage rate will aide in
determining the validity of mass removal calculations.
6.3 ]Evaluation
The data collected weekly (e.g., flow rate, sample analysis results) will be evaluated to determine
the remedial progress and forecast the estimated time required to achieve cleanup goals.
i
Progress reports will be issued quarterly that will provide the following:
o Scaled maps indicating the locations of the extraction well, soil vapor probes, and other
pertinent remediation system features;
o Vapor flow rate at the extraction well;
o Applied vacuum at the extraction well;
o Vapor influent and effluent PCE concentrations;
o Hours of system operation;
o Sample analysis results including quality assurance/quality control (QA/QC) data;
o Tabular and graphical summaries of contamination mass removed over time.
The remediation system will be operated continuously until PCE concentrations in extracted soil
vapor are either non-detectable or asymptotic, at which point AEI will request permission from
the BFD to cease SVE operations for rebound testing. The subsurface will be allowed to
O equilibrate for a period of time before restarting the SVE system. The site will be considered
remediated to the fullest extent feasible via SVE when the rebound of PCE concentrations is
insignificant (i.e., the bulk of the sorbed PCE in soil has been removed). A rebound test may
need to be conducted several times to determine that the site has been sufficiently remediated.

6.4 Confirmation Testing and Closure Application
Once data indicate that cleanup goals have been achieved, AEI will collect soil samples in areas
with previously elevated contaminant concentrations, and analyze the samples for VOCs via
a EPA Method 8260B to confirm that SVE has lowered contaminant concentrations to below
remediation goals. (A goal of 90% reduction in contaminant level is a recognized limit for
SVE.) AEI will issue a closure report to the BFD with confirmation sampling analysis results
Oand request case closure.
6.5 Well Decommissioning
0 AEI will decommission the extraction well, soil vapor probes, SVE unit, associated piping,
electrical source, and fencing.

aThis RAP has been prepared for the BFD on behalf of Red Mountain Retail Group, Inc. as it
pertains to the property located at 4200 Stine Road, Unit E in the City of Bakersfield, California.
The completed work includes observations and descriptions of site conditions encountered.
0 Where appropriate, it includes analytical results for samples taken during the course of the work.
All conclusions and/or recommendations are based on these analyses and observations and the
governing regulations. Conclusions beyond those stated and reported herein should not be
inferred from this document.
The number and location of samples were chosen to provide the required information, but it
cannot be assumed that they are representative of areas not sampled. The variations that may
exist between sampling points cannot be anticipated, nor could they be entirely accounted for, in
spite of exhaustive additional testing.
This report should not be regarded as a guarantee that no further contamination beyond that
which could have been detected within the scope of this investigation is present beneath the
1 Property. Undocumented, unauthorized releases of hazardous material, the remains of which are
not readily identifiable by visual inspection and are of different chemical constituents, are
difficult and often impossible to detect within the scope of a chemical specific investigation.

' • Site Supervisors and Project Managers (SS/PM): Responsibility for compliance with AEI Health and Safety programs, policies,
procedures and applicable laws and regulations is shared by all AEI management and supervisory personnel. This includes the need for
effective oversight and supervision of project staff necessary to control the Health and Safety aspects of AEI on-site activities.
• Site Safety Officers and Competent Persons(SSO): The Site Safety Officer(SSO),as defined by OSHA 1926.20(b),is the individual
"who is capable of identifying existing and predictable hazards in surroundings or working conditions which are unsanitary, hazardous, or
dangerous to employees,and who has authorization to take prompt corrective measures to eliminate them." The SSO is designated on a site-
by-site basis based on the site conditions, scope-of-work, and the individual's ability to recognize site-specific hazards and take appropriate
' corrective actions. This individual is responsible to both project management and the designated Office Health and Safety Officer(HSO)with
regard to the completion of these assigned duties.
• Staff: Ultimate control of Health Safety is in the hands of each individual employee. Therefore,each employee must become familiar
' with and comply with all Health and Safety requirements associated with their position and daily operations. Employees also have the
responsibility to notify the appropriate management, SSO, and/or HSO of unsafe conditions and accidents/injuries immediately. When
employees are issued respirators or any other personal protective equipment(PPE),they are responsible for ensuring that said items are used
properly,cleaned as required and maintained in good working order.
• (Sub)contractors: (Sub)contractors should develop their own site safety plan related to their specific on-site activities. Subcontractors
may use AEI's plan as an informational model. However, each Subcontractor is responsible for determining the plan's adequacy and

If symptoms persist,medical attention should be sought as soon as possible.
Ingestion—Seek immediate medical attention.
Inhalation—Any warning symptoms such as headache,dizziness,nausea,shortness of breath,etc.necessitate that the victim
' leave the immediate site area rapidly. If the victim stops breathing,assisting personnel should don breathing protection while
removing them from the area. Persons trained in CPR should immediately begin initiated,while medical attention should be
obtained as soon as possible.
' In case of evacuation, all vehicles/equipment should be turned off and personnel should immediately leave the work area.
Personnel should reconnoiter at the specified meeting area located upwind of the affected area,such as the building exterior,
site field office,property boundary,or other predesignated location,where all personnel will be accounted for.
' IF AN EMERGENCY ARISES THE DESIGNATED RECONNOITER LOCATION FOR THIS PROJECT IS THE
EXTERIOR OF THE SUBJECT PROPERTY BUILDING AT THE HOLIDAY CLEANERS PARKING LOT
ALONG STINE ROAD. This location is located up-wind of the subject property,but is subject to change if prevailing
weather conditions alter typical wind direction.
Personnel should not reenter the work area following evacuation until: 1.)the condition causing the emergency has been
' corrected. 2.)All hazards have been assessed. 3.)The HASP has been reviewed. 4.)Personnel have been oriented on any
changes in the HASP.

resam le before resuming activity.
' Atmospheric vapor concentrations will be monitored via a photoionization detector(PID)or equivalent to determine
appropriate action levels. The PID will be calibrated daily by AEI personnel prior to use. Calibration will be performed in
' accordance with the manufacturer specifications and recorded in a log book kept with the instrument. Ambient breathing
space measurements should be collected every 15 minutes during excavation activities. Measurements will also be collected
from the interior workspace as well as the soil stockpile and down-gradient areas.
' DECONTAMINATION PROCEDURES [CAL OSHA 8 CCR 5192(k)l
All downhole soil and groundwater sampling equipment (e.g., sampling tubes, split spoons, hand augers, Hydropunch, etc),
' hand tools, purge pumps, water level indicators,etc. will be decontaminated before,between, and after use with Alconox or
an equivalent phosphate-free detergent solution to reduce the risk of cross-contamination.
Decontamination of all sampling equipment will consist of submerging the equipment in a detergent solution bath and
scrubbing it with dedicated brushes. The equipment will then be placed in a rinse bath and agitated. A second rinse bath
should occur if needed.
' All construction equipment such as excavators and should be thoroughly steam cleaned and rinsed.
EMPLOYEE TRAINING [CAL OSHA 8 CCR 5192(e)l
All personnel working on-site,must have had at a minimum the required 24-or 40-hour OSHA training for HAZWOPER
with the annual 8-hour refresher,which includes the use of respirators and PPE. Annual individualized respirator fit testing
is required of all applicable AEI employees working at the site.
During daily the Site Health and Safety Briefing or "Tailgate Safety Meeting", at a minimum the following should be
discussed: 1.) Scope of work, including personnel project responsibilities. 2.) A description of the levels of personal
protection at the site and the steps taken to select each level. 3.) Emergency procedures. 4.) Nature of the known or
' anticipated hazards, including the location of the Material Safety Data Sheets (MSDS) for the chemicals at the site. 5.)
Review safe work practices and identify any prohibited or forbidden practices. 6.)Permissible smoking location.
' Attendance at the Site Health and Safety Briefing or"Tailgate Safety Meeting"will be mandatory and all personnel coming
on-site following the initial daily meeting will be subject to their own Site Health and Safety Briefing prior to entering the
site. All personnel will be required to sign the Health and Safety Briefing/Site Orientation Record to signify understanding and
' adherence to AEPs HASP.

OHAZARD ASSESSMENT
(® =Applies, or required item(s)available. ❑ =Not Applicable)
OHAZARD ASSESSMENT: PHYSICAL HAZARDS AND RELATED CONCERNS(CAL OSHA 8 CCR 5192)
o ❑ Confined Space Entry(CSE). Confined space entry means the potentially hazardous entry into any space which,by design,has limited
openings for entry and exit,unfavorable natural ventilation which could contain or produce dangerous air contaminants,and which is not
intended for continuous employee occupancy. Confined spaces include but are not limited to storage tanks, compartments of ships,
process vessels, pits, silos,vats, degreasers, reaction vessels,boilers,ventilation and exhaust ducts, sewers,tunnels,underground utility
o vaults,and pipelines. Other environments which must be treated as confined spaces include test pits,and basements,garages, warehouses
and other indoor areas where mechanical(i.e.,diesel,propane,gasoline or similarly powered)equipment must be operated for drilling or
test pitting purposes. Confined space entry should be allowed only when absolutely necessary, and then only when all requirements of
D AEI's Confined Space Entry Control Program, and/or CSE Program Supplement for Indoor Drilling (and Similar Operations) and/or
Trench and Excavation Safety and Health Guide(and CSE Program Supplement),contained in the Health and Safety Program Manual,
have been satisfied.
® Construction Hazards, Drill Rigs, Backhoes, etc. The use of drill rigs, backhoes and other heavy equipment represent potentially
serious construction hazards. Whenever such equipment is used,personnel in the vicinity should be limited to those who must be there to
complete their assigned duties. All personnel must avoid standing within the turning radius of the equipment or below any suspended
load. Job sites must be kept as clean,orderly and sanitary as possible. When water is used,care must be taken to avoid creating muddy or
slippery conditions.
DNever turn your back to operating machinery. Never wear loose clothing jewelry,hair or other personal items around rotating equipment
or other equipment that could may catch or ensnare loose clothing,jewelry,hair or other personal items. Always stand far enough away
from operating machinery to prevent accident contact which may result from mechanical or human error.
O Additionally,the following basic personal protective measures must be observed: Hardhats must be wom to protect against bumps or
falling objects. Safety glasses must be worn when necessary to protect against chemicals or other hazards. Steel-toed safety shoes or
boots are also required. The shoes must be chemically resistant or protected with appropriately selected boots/coverings where necessary.
o Unless otherwise specified,normal workclothes must be worn. Gloves are also required whenever necessary to protect against hazardous
contact,cuts,abrasions or other possible skin hazards.
❑ Drums and Buried Drums. As a precautionary measure,personnel must assume that labeled and unlabeled drums encountered during
o field activities contain hazardous materials until their contents can be confirmed and characterized. Personnel should recognize that drums
are frequently mislabeled,particularly drums that are reused.
Only trained and authorized personnel should be allowed to perform dram handling. Prior to any handling, drums must be visually
inspected to gain as much information as possible about their contents. Trained field personnel must look for signs of deterioration such as
corrosion,rust or leaks,and for signs that the drum is under pressure such as swelling or bulging. Dram-type and drumhead configuration
may provide the observer with information about the type of material inside,(i.e.,a removable lid is designed to contain solids,while the
presence of a bung indicates liquid storage).
(� Although not usually anticipated,buried drums can be encountered when digging test pits. Therefore,the following provisions must be
Uobserved if drums are encountered. Machine excavation(i.e.,backhoe)should cease immediately anytime a drum is encountered. The
appropriate management personnel should be notified immediately. All AEI personnel should be instructed to immediately leave the work
area.
o ® Fire and Explosion. The possibility of flammable materials being encountered during field activities must be recognized and the
appropriate steps necessary to minimize fire and explosion must be observed. This includes situations where excessive organic vapors or
free product are encountered. When this occurs,monitoring with a combustible gas indicator(CGI),is required.
O Excessive organic vapors,for the purposes of initiating the use of a CGI,are defined as sustained readings(i.e.,continuous for at least five
minutes)at or above 250 units or as an instantaneous reading at or above 1,000 units on the PID or FID,in close proximity(within 1 foot
or less)of the borehole,test pit,sampling location or other area of potential exposure.
o In situations where hexane, methanol are needed for field activities,the following precautions must be observed: keep flammable and
combustible materials away from heat,sparks and open flames; do not smoke around flammable or combustible materials; and keep all
flammable and combustible liquids in approved and properly labeled safety containers.
o ❑ Landfill/Methane Hazards. Fire and explosion should be regarded as one of, if not the,most significant potential hazards associated
with drilling operations and other intrusive work conducted at a landfill. Accordingly, all sources of ignition must be fully controlled.
Failure to control ignition sources could result in fire,explosion and pose a serious threat to life and health. Control methods may include
o forced ventilation and/or filling the borehole with enough water to inhibit the release of methane and other gases which would otherwise
escape through the top of the borehole.
o AEI Site-Specific Health,Safety and Accident Prevention Plan Page 6
April 13,2007
DIf forced(mechanical)ventilation is to be used,all such equipment must be approved for Class I,Division I hazardous atmospheres. The
blower must be positioned to blow across the top of the borehole so that gases and vapors may be diluted as they exit the borehole.Do not
attempt to suck out the gases or vapors. Blowers,all other mechanical equipment,and tools which could release sparks or static electricity
must be bonded and grounded.
Regardless of the gas/vapor control method used, the atmosphere surrounding the borehole must be frequently monitored using direct
reading instruments approved for Class I,Division I hazardous atmospheres. Monitoring should be conducted within 1 to 2 feet of the top
of the borehole. Do not insert sampling devices into the borehole. Never approach the auger or drill shaft while it is in operation.
Regardless of actual instrument readings,if all sources of ignition can not be controlled,operations should be immediately shut down if
readings equal or exceed 10%of LEL and the area evacuated until ignition sources have been eliminated. Ignition sources include,but are
D not limited to: smoking,static electricity,lighting,open flames,spontaneously ignitable substances,frictional heat or sparks,hot surfaces,
radiant heat,electrical sparks,stray currents,cutting and welding,and ovens,furnaces and heating equipment.
® Heat and Cold Stress. Overexposure to temperature extremes can represent significant risks to personnel if simple precautions are not
observed. Typical control measures designed to prevent heat stress include dressing properly, drinking plenty of the right fluids, and
establishing an appropriate work/break regimen. Typical control measures designed to prevent cold stress also include dressing properly,
and establishing an appropriate work/break regimen.
® Moving Vehicles,Traffic Safety. All vehicular traffic routes which could impact worker safety must be identified and communicated.
Whenever necessary,barriers or other methods must be established to prevent injury from moving vehicles. This is particularly important
when field activities are conducted in parking lots,driveways,ramps or roadways
® Noise. Noise exposure can be affected by many factors including the number and types of noise sources(continuous vs. intermittent or
impact),and the proximity to noise intensifying structures such walls or building which cause noise to bounce back or echo. The single
most important factor effecting total noise exposure is distance from the source. The closer one is to the source the louder the noise. The
operation of a drill rig, backhoe or other mechanical equipment can be sources of significant noise exposure. In order to reduce the
exposure to this noise,personnel working in areas of excessive noise must use hearing protectors(ear plugs or ear muffs).
0 Rule-of-Thumb: Wherever actual data from sound level meters or noise dosimeters is unavailable and it is necessary to raise one's voice
above a normal conversational level to communicate with others within 3 to 5 feet away,hearing protection should be worn.
® Overhead Utilities and Hazards. Overhead hazards can include low hanging structures which can cause injury due to bumping into
them. Other overhead hazards include falling objects,suspended loads,swinging loads and rotating equipment. Hardhats must be worn
by personnel in areas were these types of physical hazards may be encountered. Barriers or other methods must also be used to exclude
personnel from these areas were appropriate. Electrical wires are another significant overhead hazard. According to OSHA (29 CFR
1926.550),the minimum clearance which must be maintained from overhead electrical wires is 10 feet from an electrical source rated<50
kV. Sources rated>50 kV require a minimum clearance of 10 feet plus 0.4 inch per kV above 50 kV.
® Pedestrian Traffic. The uncontrolled presence of pedestrians on a drilling or excavation site can be hazardous to both pedestrians and
site workers. The site should be surveyed to determine if,when and where pedestrian may gain access. This includes walkways,parking
lots, gates and doorways. Barriers or caution tape should be used to exclude all pedestrian traffic. Exclusion of pedestrian traffic is
intended to prevent injury to the pedestrians and eliminate distractions which could cause injury to AEI personnel or other site workers.
® Test Pit and/or other Excavations. All provisions of the OSHA trenching and excavation standard (29 CFR 1926.650-652) must be
followed during excavation activities. This includes all test pit excavation and sampling activities. The estimated location of utility
installations, such as sewer, telephone, electric, water lines and other underground installations that may reasonably be expected to be
encountered during excavation work,must be determined prior to opening an excavation.
A ladder or similar means of egress must be located in excavations greater than 4 feet in depth so as to require no more than 25 feet of
lateral travel for employees. No person should be allowed to enter an excavation greater than 5 feet in depth unless the walls of the
excavation have been protected using an approved shield(trench box),an approved shoring system,or the walls have been sloped back to
an angle of 34 degrees,and the excavation is free of accumulated water. If personnel enter an excavation,the spoils pile and all materials
must be placed at least 2 feet from the edge of the excavation to prevent the materials from rolling into the excavation. Personnel must
remain at least 2 feet away from the edge of the excavation at all times. Upon completion of a test pit exploration,the excavation should
be backfilled and graded. Excavation should never be left open unless absolutely necessary,and then only with proper barricading and
controls to prevent accidental injury.
® Underground Utilities and Hazards. The identification of underground storage tanks (USTs), pipes, utilities and other underground
hazards is critically important prior to all drilling,excavating and other intrusive activities. In accordance with OSHA 29 CFR 1926.650,
the estimated location of utility installations,such as sewer, telephone, electric, water lines and other underground installations that may
reasonably be expected to be encountered during excavation work, must be determined prior to opening an excavation. The same
requirements apply to drilling operations and the use of soil-gas probes. Where public utilities may exist,the utility agencies or operators
must be contacted directly or through a utility-sponsored service such as Dig-Safe. Where other underground hazards may exist,
reasonable attempts must be made to identify their locations as well. Failure to identify underground hazards can lead to fire, explosion,
flooding,electrocution or other life threatening accidents.

April 13,2007
❑ ❑ Water Hazards and Boat Sampling. The collection of water or sediment samples on or immediately adjacent to a body of water can
pose significant hazards. In addition to the slip,trip and fall hazards associated with wet surfaces,the potential for drowning accidents
must be recognized. These hazards can be intensified by the use of some PPE,particularly if respiratory protection is wom.
❑ HAZARD ASSESSMENT: CHEMICAL HAZARDS AND RELATED CONCERNS(CAL OSHA 8 CCR 5192)
® Chemicals Subject to OSHA Hazard Communication. All chemicals used in field activities such as solvents, reagents,
❑ decontamination solutions, or any other hazardous chemical must be accompanied by the required labels, Material Safety Data Sheets
(MSDS),and employee training documentation(OSHA 1910.1200). For additional information refer to AEI's Hazard Communication
Program contained in the Health and Safety Program manual.
❑ ❑ Asbestos. Disturbance of building materials in buildings built prior to 1980 must be evaluated for the presence of asbestos-containing
materials by an accredited AEI inspector. The inspection and/or removal of asbestos-based or asbestos-containing building materials is
regulated by some major cities and several states. Regulations require individuals who conduct building inspections for the presence of
asbestos or collect samples of asbestos containing materials to be licensed or certified. AEI employees must determine the applicability of
❑ these regulations prior to any activities involving asbestos. The primary health effects of asbestos exposure include asbestosis(a scarring
of the lungs), lung cancer, mesothelioma and other forms of cancer. Exposure to asbestos is regulated by a comprehensive OSHA
standard(29 CFR 1910.1001).
❑ ❑ BTEX Compounds. Exposure to the vapors of benzene,ethyl benzene,toluene and xylenes above their respective permissible exposure
limits (PELs), as defined by the Occupational Safety and Health Administration (OSHA), may produce irritation of the mucous
membranes of the upper respiratory tract,nose and mouth. Overexposure may also result in the depression of the central nervous system.
Symptoms of such exposure include drowsiness, headache, fatigue and drunken-like behavior. Benzene has been determined to be
❑ carcinogenic,targeting blood-forming organs and bone marrow. The odor threshold for benzene is higher than the PEL and employees
may be overexposed to benzene without sensing its presence,therefore,detector tubes must be utilized to evaluate airborne concentrations.
The vapor pressures of these compounds are high enough to generate significant quantities of airborne vapor. On sites where high
❑ concentrations of these compounds are present,a potential inhalation hazard to the field team during subsurface investigations can result.
However,if the site is open and the anticipated quantities of BTEX contamination are small(i.e.,part per million concentrations in the soil
or groundwater),overexposure potential will also be small.
❑ ❑ Carbon Monoxide. Carbon monoxide(CO)is a gas usually formed by the incomplete combustion of various fuels. Welding,cutting and
the operation internal combustion engines can produce significant quantities of CO. Amounts of CO can quickly rise to hazardous levels
in poorly ventilated areas. CO is odorless and colorless. It cannot be detected without appropriate monitoring equipment. LEL/02 meters
and H-Nu/photoionizing detectors are not appropriate for the detection of CO. A direct reading instrument,calibrated for CO,should be
❑ used. Common symptoms of overexposure include pounding of the heart,a dull headache,flashes before the eyes,dizziness,ringing in
the ears and nausea. These symptoms must not be relied upon in place of an appropriately calibrated monitoring instrument. Exposures
should not exceed 15 ppm. Exposures above 15 ppm require the use of supplied air respirators. Air purifying respirators are not approved
for protection against CO.
❑ ® Chlorinated Organic Compounds. Exposure to the vapors of many chlorinated organic compounds such as vinyl chloride,
tetrachloroethene, 1,1,1-trichloroethane,trichloroethee and 1,2-dichloroethene above their respective pennissible exposure limits(PELs)
will result in similar symptoms. The actual PELs as set by the Occupational Safety and Health Administration(OSHA)vary depending
❑ on the specific compound.
Overexposure to the vapor of these compounds can cause irritation of the eyes,nose and throat. The liquid if splashed in the eyes,may
cause burning irritation and damage. Repeated or prolonged skin contact with the liquid may cause dermatitis. Acute overexposure to
❑ chlorinated hydrocarbons depresses the central nervous system exhibiting such symptoms as drowsiness, dizziness, headache, blurred
vision, in-coordination, mental confusion, flushed skin, tremors, nausea, vomiting, fatigue and cardiac arrhythmia. Alcohol may make
symptoms of overexposure worse. If alcohol has been consumed, the overexposed worker may become flushed. Some of these
compounds are considered to be potential human carcinogens. Exposure to vinyl chloride is regulated by a comprehensive OSHA
❑ standard(29 CFR 1910.1017).
❑ Chromium Compounds. Hexavalent chromium compounds,upon contact with the skin can cause ulceration and possibly an allergic
reaction. Inhalation of hexavalent chromium dusts is irritating and corrosive to the mucous membranes of the upper respiratory tract.
❑ Chrome ulcers and chrome dermatitis are common occupational health effects from prolonged and repeated exposure to hexavalent
chromium compounds. Acute exposures to hexavalent chromium dusts may cause coughing or wheezing, pain on deep inspiration,
tearing,inflammation of the conjunctiva,nasal itch and soreness or ulceration of the nasal septum. Certain forms of hexavalent chromium
have been found to cause increased respiratory cancer among workers.
❑ Trivalent chromium compounds (chromic oxide) are generally considered to be of lower toxicity, although dermatitis may occur as a
result of direct handling.
❑ Cutting Oils. Cutting oils may produce a condition known as "cutting oil acne," a specific dermatosis associated with prolonged and
❑ repeated direct contact. Other problems associated with continued occupational exposure to cutting fluids include allergic skin
sensitization,folliculitis and squamous cell carcinoma,due to the presence of nitrosamines.

a
❑ ❑ Fuel Oil. See Petroleum Hydrocarbons(PHC)
❑ Gasoline. See BTEX Compounds,and Tetraethyl and Tetramethyl Lead.
❑ ❑ Herbicides. Some of the commonly used herbicides present a low toxicity to man. However, other herbicides pose more serious
problems. Organophosphorus and carbamate herbicides, if inhaled or ingested can interfere with the functioning of the central nervous
system. Many herbicides can be readily absorbed through the skin to cause systemic effects. In addition to being absorbed through the
❑ skin, many herbicides, upon contact with the skin, may cause discoloring, skin irritation or dermatitis. Contaminants of commercial
preparations of chlorinated phenoxy herbicides such as 2,4,5-T include 2,3,7,8-tetrachlorodibenzo-p-dioxin(dioxin). Dioxin is a known
mutagen and a suspect carcinogen.
❑ Hydrogen Sulfide(HZS). Hydrogen sulfide,characterized by its"rotten egg"odor,is produced by the decomposition of sulfur-containing
❑ organic matter. It is found in many of the same areas where methane is found such as landfills, swamps, sewers and sewer treatment
facilities. An important characteristic of HZS is its ability to cause a decrease in ones ability to detect its presence by smell. So although
one may no longer be able to smell it,it could still be present in harmful concentrations.
❑ The symptoms of over exposure include headache,dizziness,staggering and nausea. Severe over exposure can cause respiratory failure,
coma,and death. The current OSHA PEL is 10 ppm as an 8-hour TWA. The ACGIH TLV is the same.
❑ Lead Paint. The inspection and/or removal, sanding,grinding, etc. of lead-based or lead-containing paints is now strictly regulated by
❑ OSHA. States may require individuals who conduct lead paint inspections or collect samples of lead paint to be licensed or certified. AEI
employees must determine the applicability of these regulations prior to any activities involving lead paint. For additional health
information,see Metal Compounds.
❑ ❑ Metal Compounds. Overexposure to metal compounds has been associated with a variety of local and systemic health hazards, both
acute and chronic in nature,with chronic effects being most significant. Direct contact with the dusts of some metal compounds can result
in contact or allergic dermatitis. Repeated contact with arsenic compounds may result in hyperpigmentation. Cases of skin cancer due to
the trivalent inorganic arsenic compounds have been documented. The moist mucous membranes,particularly the conjunctivae,are most
❑ sensitive to the irritating effects of arsenic. Copper particles embedded in the eye result in a pronounced foreign body reaction with a
characteristic discoloration of eye tissue.
Inhalation of copper and zinc dusts and fumes above their established PELs may result in flu-like symptoms known as"metal fume fever."
❑ Prolonged and repeated inhalation of the dusts of inorganic arsenic compounds above the established PEL may result in weakness,loss of
appetite, a sense of heaviness in the stomach and vomiting. Respiratory problems such as cough, hoarseness and chest pain usually
precede the gastrointestinal problems. Chronic overexposure to the dusts of inorganic arsenic may result in lung cancer.
❑ The early symptoms of lead poisoning are usually nonspecific. Symptoms include sleep disturbances, decreased physical fitness,
headache,decreased appetite and abdominal pains.Chronic overexposure may result in severe colic and severe abdominal cramping. The
central nervous system (CNS) may also be adversely effected when lead is either inhaled or ingested in large quantities for extended
periods of time. The peripheral nerve is usually affected. "Wrist drop"is peculiar to such CNS damage. Lead has also been characterized
D as a male and female reproductive toxin as well as a fetotoxin. Exposure to lead(Pb)is regulated by a comprehensive OSHA standard(29
CFR 1910.1025).
❑ Methane. Methane is an odorless,colorless,tasteless,gas that cannot be detected by an H-Nu or similar photoionizing detector(PID).
❑ When present in high concentrations in air,methane acts primarily as a simple asphyxiant without other significant physiologic effects.
Simple asphyxiants dilute or displace oxygen below that required to maintain blood levels sufficient for normal tissue respiration.
Methane has a lower explosive limit(LEL)of 5 percent and an upper explosive limit(UEL)of 15 percent. The LEL of a substance is the
minimum concentration of gas or vapor in air below which the substance will not burn when exposed to a source of ignition. This
❑ concentration is expressed in percent by volume. Below this concentration,the mixture is"too lean"to burn or explode. The UEL of a
substance is the maximum concentration of gas or vapor in air above which the substance will not burn when exposed to a source of
ignition. Above this concentration, the mixture is "too rich" to burn or explode. The explosive range is the range of concentrations
between the LEL and UEL where the gas-air mixture will support combustion. For methane this range is 5 to 15 percent.
❑ ® MTBE. Methyl tertiary butyl ether(MTBE)is a volatile,flammable and colorless liquid that is relatively soluble in water. MTBE has a
typical odor reminiscent of diethyl ether, leading to unpleasant taste and odor in water. MTBE is almost exclusively used as a fuel
component in motor gasoline. The EPA has concluded that available data are not adequate to estimate potential health risks of MTBE at
❑ low exposure levels in drinking water,but that the data support the conclusion that MTBE is a potential human carcinogen at high doses.
The ACGIH has recommended an exposure limit of 40 parts of MTBE per million parts of air(40 ppm)for an 8-hour workday,40-hour
workweek.
❑ ❑ Pesticides. Pesticides can be grouped into three major categories:organophosphates,carbonate and chlorinated hydrocarbons. The actual
PELs as set by the OSHA,vary depending on the specific compound. Organophosphates,including Diazinon,Malathion and Parathion,
are quickly absorbed into the body by inhalation,ingestion and direct skin contact. The symptoms of exposure include headache,fatigue,
dizziness, blurred vision, sweating, cramps, nausea and vomiting. More severe symptoms can include tightness of the chest, muscle
❑ spas ms, seizures and unconsciousness. It should also be noted that the Malathion and Parathion PELs both carry the Skin notation,
❑
AE]Site-Specific Health,Safety and Accident Prevention Plan Page 9
April 13,2007
indicating that these compounds adversely effect or penetrate the skin. OSHA specifies that skin exposure to substances carrying this
designation be prevent or reduced through the use of the appropriate PPE.
❑ Chlorinated Hydrocarbons such as Chlordane,DDT and Heptachlor can cause dizziness,nausea,abdominal pain and vomiting. The more
severe symptoms include epileptic like seizures,rapid heart beat,coma and death. These compounds also carry the OSHA Skin notation.
The symptoms of exposure to carbamate such Carbaryl (also known as Sevin)are similar to those described for the organophosphates.
However,the OSHA exposure limit for Carbaryl does not carry the Skin notation.
❑ ❑ Petroleum Hydrocarbons (PHCs). Petroleum Hydrocarbons such as fuel oil are generally considered to be of low toxicity.
Recommended airborne exposure limits have not been established for these vapors. However, inhalation of low concentrations of the
vapor may cause mucous membrane irritation. Inhalation of high concentrations of the vapor may cause pulmonary edema. Repeated or
❑ prolonged direct skin contact with the oil may produce skin irritation as a result of defatting. Protective measures,such as the wearing of
chemically resistant gloves, to minimize contact are addressed elsewhere in this plan. Because of the relatively low vapor pressures
associated with PHCs,an inhalation hazard in the outdoor environment is not likely.
❑ Polychlorinated Biphenyls(PCBs). Prolonged skin contact with PCBs may cause the formation of comedones,sebaceous cysts,and/or
❑ pustules(a condition known as chloracne).PCBs are considered to be suspect carcinogens and may also cause reproductive damage.
The OSHA permissible exposure limits(PELs)for PCBs are as follows:
❑ Compound PEL(8-hour time-weighted average)
Chlorodiphenyl(42%Chlorine) 1 mg/m3-Skin
Chlorodiphenyl(54%Chlorine) 0.5 mg/m3-Skin
❑ It should be noted that PCBs have extremely low vapor pressures(0.001 mm Hg(-0,42%Chlorine and 0.00008 mm Hg @ 54%Chlorine).
This makes it unlikely that any significant vapor concentration (i.e., exposures above the OSHA PEL) will be created in the ambient
environment. This minimizes the potential for any health hazards to arise due to inhalation unless the source is heated or generates an
airborne mist. If generated,vapor or mists above the PEL may cause irritation of the eyes,nose,and throat. The exposure limits noted
❑ above are considered low enough to prevent systemic effects but it is not known if these levels will prevent local effects. It should also be
noted that both PELs carry the Skin notation,indicating that these compounds adversely effect or penetrate the skin. OSHA specifies that
skin exposure to substances carrying this designation be prevented or reduced through the use of the appropriate personal protective
equipment(PPE).
❑ ❑ Polycyclic Aromatic Hydrocarbons(PAHs). Due to the relatively low vapor pressure of PAH compounds, vapor hazards at ambient
temperatures are not expected to occur. However, if site conditions are dry, the generation of contaminated dusts may pose a potential
inhalation hazard. Therefore dust levels should be controlled with wetting if necessary. Repeated contact with certain PAH compounds
❑ has been associated with the development of skin cancer. Contact of PAH compounds with the skin may cause photosensitization of the
skin, producing skin burns after subsequent exposure to ultraviolet radiation. Protective measures, such as the wearing of chemically
resistant gloves,are appropriate when handling PAH contaminated materials.
❑ Tetraethyl and Tetramethyl Lead. Both compounds are used as anti-knock ingredients in gasoline. The inhalation of tetraethyl lead
❑ dusts may result in irritation of the respiratory tract. This dust,when in contact with moist skin or eye membranes,may cause itching,
burning and transient redness.
The direct absorption of a sufficient quantity of tetraethyl lead,whether briefly at a high rate,or for prolonged periods at a low rate,may
❑ cause acute intoxication of the central nervous system. Mild degrees of intoxication may cause headache, anxiety, insomnia, nervous
excitation and minor gastrointestinal disturbances.
® Volatile Organic Compounds(VOCs). See BTEX compounds and Chlorinated Organic Compounds.
❑ ❑ Waste Oil. See Petroleum Hydrocarbons(PHCs)and Cutting Oil.
❑ HAZARD ASSESSMENT: BIOLOGICAL HAZARDS AND RELATED CONCERNS(CAL OSHA S CCR 5192)
❑ Insects. Insects represent significant sources (vectors) of disease transmission. Therefore, precautions to avoid or minimize potential
contact should be considered prior to all field activities. Disease or harmful effects can be transmitted through bites, stings or through
❑ direct contact with insects or through ingestion of foods contaminated by certain insects. Examples of disease transmitted by insect bites
include encephalitis and malaria from contaminated mosquitoes,lyme disease and spotted fever from contaminated ticks. Stinging insects,
such as bees and wasps,are prevalent throughout the country,particularly during the warmer months. The stings of these insects can be
painful,and cause serious allergic reactions to some individuals.
❑ ❑ Lyme Disease. Lyme disease is an infection caused by the bite of certain ticks,primarily deer,dog and wood ticks. The symptoms of
Lyme disease usually start out as a skin rash then progress to more serious symptoms. The more serious symptoms can include lesions,
headaches, arthritis and permanent damage to the neurological system. If detected early the disease can be treated successfully with
❑ antibiotics. The following steps are recommended for prevention of lyme disease and other diseases transmitted by ticks:a)Beware of tall
grass,bushes,woods and other areas where ticks may live;b) Wear good shoes, long pants tucked into socks, a shirt with a snug collar,
good cuffs around the wrists and tails tucked into the pants.Insect/tick repellents may also be useful;c)Carefully monitor for the presence
❑ AEI Site-Specific Health,Safety and Accident Prevention Plan Page 10

0
0 of ticks. Carefully inspect clothes and skin when undressing. If a tick is attached to the skin it should be removed with fine tipped
tweezers. You should be alert for early symptoms over the next month or so. If you suspect that you have been bitten by a tick you should
contact a physician for medical advice.
❑ Medical Wastes and Bloodborne Diseases. Any field activity where exposure to medical wastes or other sources of bloodbome
pathogens can be reasonably anticipated must be conducted in accordance with the OSHA(29 CFR 1910.1030)Bloodborne Pathogens
standard. According to the OSHA definition,Bloodborne Pathogens means pathogenic microorganisms that are present in human blood
and can cause disease in humans. These pathogens include but are not limited to hepatitis B virus (HBi7 and human immunodeficiency
virus(HIV). Wherever there is a potential for employee skin,eye,mucous membrane,or parenteral(skin or membrane piercing)contact
with blood or other potentially infectious sources,employers must develop a Written Exposure Control Plan.
0 ❑ Poisonous Plants. The possible presence of poisonous plants should be anticipated for field activities in wooded or heavily vegetated
areas. Poison ivy is a climbing plant with alternate green to red leaves(arranged in threes)and white berries. Poison oak is similar to
poison ivy and sumac but its leaves are oak-like in form. The leaves of these poisonous plants produce an irritating oil which causes an
intensely itching skin rash and characteristic blister-like lesions. Contact with these plants should be avoided.
0 ❑ Rats, Snakes and Other Vermin. Certain animals, particularly those that feed on garbage and other wastes,can represent significant
sources (vectors)of disease transmission. Therefore, precautions to avoid or minimize potential contact with (biting) animals(such as
rats)or animal waste(such as pigeon droppings)should be considered prior to all field activities. Rats,snakes and other wild animals can
0 inflict painful bites. The bites can poisonous (as in the case of some snakes), or disease causing (as in the case of rabid animals).
Avoidance of these animals is the best protection.
❑ Waste Water and Sewage. Sewage and waste water contaminated with raw, untreated sewage can represent significant sources of
bacterial,viral or fungal contamination. Adverse effects,due to contact,can range from mild skin reactions or rashes to life threatening
diseases. Diseases are easily transmitted by accidental ingestion or through skin contact,particularly if the skin is broken. Avoidance of
direct contact and good personal hygiene are the best protection from these hazards.

Subcontractor's Statement of Understanding
Regarding Health and Safety Responsibilities
aProject Name: Red Mountain Retail Group,Inc. /Holiday Cleaners
OProject Number: 271444
In accordance with generally accepted practices, each Subcontractor engaged by AEI is responsible for all matters relating to the
health and safety of its personnel and equipment in performance of the work. This includes recognition of the potential health and
O safety hazards associated with the work. AEI will establish a health and safety plan or program (HASP) applicable to its own
employees and its own activities on site. AEI will make its HASP available to each subcontractor for informational purposes only.
Each subcontractor must establish a HASP applicable to its own employees and its own activities on site.
Subcontractors who use AEI's HASP as a model for their own HASP are responsible for determining its adequacy and applicability
to its own employees and its own activities on site. Subcontractors must establish their own HASP applicable to subcontractor
employees and/or activities, even if modeled after AEI's HASP and deliver this HASP in clear written form to AEI prior to the
O initiation of on-site activities. Submittal of the subcontractor's HASP to AEI will be for informational purposes only.Review of the
subcontractor's HASP by AEI shall in no way constitute approval or endorsement by AEI of the subcontractor's HASP. It is
understood that protective measures specified in the Subcontractor's HASP are minimum requirements for the work.
Subcontractor warrants that all its employees that are permitted to engage in operations that could expose them to hazardous wastes,
hazardous substances,or safety or health hazards have obtained the necessary health and safety training and medical surveillance as
specified in the applicable provisions of OSHA:
O 1926.59 Hazard Communication,
1926.52 Occupational Noise Exposure,
1926.103 Respiratory Protection,
1926.65 Hazardous Waste Operations and Emergency Response;
0 as well as any other applicable portion of the OSHA General Industry (29 CFR 1910) and Construction Industry (29 CFR 1926)
Standards. Subcontractor shall provide AEI with evidence of the necessary certification before beginning hazardous waste work
subject to OSHA 1926.65 on the project site.
DShould AEI become aware of subcontractor activities on site which appear to violate OSHA or other applicable safety regulations or
otherwise pose an immediate and serious threat to the safety of AEI employees,subcontractor employees,other individuals on site,or
members of the public,AEI may notify the subcontractor verbally and/or in writing regarding the need for corrective action. Failure
O to comply with either general safety practices or health and safety practices as described above may be grounds for breach and
prompt contract termination. The safety requirements of the work as described above apply without regard to time, place, or
presence of a AEI representative.
THE PRESENCE OF AEI PERSONNEL ON THE SITE CARRYING OUT PROFESSIONAL
ACTIVITIES DOES NOT MEAN THAT AEI UNDERTAKES TO OVERSEE THE
SUBCONTRACTOR'S COMPLIANCE RESPONSIBILITIES.
