2.0 EXECUTIVE SUMMARY
The purpose of this Phase I Limited Site Assessment (LSA) is to provide the information
necessary for the North Carolina Department of Environmental Quality (NCDEQ) to evaluate the
level of risk to human health and the environment resulting from the apparent release of
petroleum-related constituents from the historical operation of three 1,000-gallon gasoline
underground storage tanks (USTs), reportedly removed in December, 1990, located at the G&B
Oil Co convenience store and gasoline service station, 1497 US-21, Sparta, Alleghany County,
North Carolina (hereafter identified as the site, subject site, subject property or property). The
site location, including topographic features, is depicted on Figure 1. CES Group Engineers, LLP
(CES) has been authorized to perform this Limited Site Assessment by NCDEQ, represented by
Scott Ryals, PE, Environmental Engineer.
A Phase I LSA of the subject property was completed by CES to evaluate if soil and groundwater
has been impacted at the site by the apparent release condition, and if the potential exists for
nearby water supply wells and/or other receptors to be impacted.
In December, 1990, a total of three 1,000-gallon gasoline USTs were reportedly removed from
the site under the direction of G&B Oil Co, of Sparta, North Carolina. No further information
regarding the removal and/or sampling of the removed USTs was readily available for review.
However, according to two Reports of Environmental Services, prepared by Law Engineering and
Environmental Services, Inc (Law), of Greensboro, North Carolina, dated February 19, 1993 and
February 22, 1994, and a Response to NCDEM Letter Dated April 16, 1996, dated June 21, 1996,
also prepared by Law, a total of 422-tons of contaminated soils were excavated from the area of
the removed 1,000-gallon gallon gasoline USTs in 1991 (dates unknown), for offsite disposal, with
one soil sample (EXC-2) collected from the base of the excavated area reporting a total petroleum
hydrocarbon (TPH) concentration of 800 parts per million (ppm). Additionally, as reported by Law,
a second excavation area completed in January, 1994, located beneath bulk above ground
storage tanks (ASTs) that were previously removed, and located to the east-northeast of the
former 1,000-gallon gasoline USTs, reported TPH concentrations below NCDEQ Action Levels.
Based upon the listed date of discovery of December 20, 1990, as referenced in Section 1.3 of
this report, it is presumed that NCDEQ subsequently issued Incident Number 7068 for an
apparent release condition identified during the removal of the three 1,000-gallon gasoline USTs
in December, 1990. The aforementioned environmental reports, prepared by Law, are included
in Appendix A.
Since the reported excavation of 422-tons of contaminated soils in 1991, and the assessment of
the bulk ASTs in January, 1994, no further assessment, monitoring and/or remediation activities
are known to have taken place at the site.
Based upon a review of historical reports, which reported rock at a depth of approximately 15-feet
below grade, on April 25, 2023, under the direction of CES, an air rotary drill rig was mobilized to
the site to install one soil boring in the former gasoline tank grave for subsequent conversion into
a 2-inch diameter permanent groundwater monitoring well to a proposed depth of 35-feet below
grade. However, during drilling activities on April 25, 2023, groundwater was not encountered to
a maximum boring exploration depth of 40-feet below grade utilizing the air rotary drilling
equipment. At this time, per conversations with Mr. Scott Ryals, NCDEQ, the boring was
terminated and it was agreed that an attempt would be made to sample perched water that was
observed immediately above the rock interface at 15-feet below grade. As a result, a 1-inch
diameter groundwater monitoring well was set within the bore hole to a depth of 20-feet below
CES Project No. 8079.0123E 7
June 5, 2023
grade and completed with 10-feet solid riser and 10-feet schedule 40 screen.
During the installation of groundwater monitoring well MW-1 on April 25, 2023, one soil sample
was collected from the soil sample exhibiting the highest photoionization detector (PID) reading
above the rock interface, at a depth of approximately 15-feet below grade, placed in laboratory
provided vials and glassware, stored on ice, and hand delivered under chain-of-custody (COC)
procedures on April 26, 2023 to Waypoint Analytical (Waypoint) of Charlotte, North Carolina (NC
Certification No. 402) for laboratory analysis of VOCs by 8260, sVOCs by 8270, Metals (Pb & Cr)
and VPH and EPH by MassDEP methodologies.
Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil to Water Maximum Soil Contaminant Concentration (MSCC):
MW-1: 1-methylnaphthalene and 2- methylnaphthalene.
Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil to Water MSCC, Residential Soil Clean Up Levels and the
Industrial/Commercial MSCC:
MW-1: chromium.
All other concentrations of petroleum-related constituents were reported below Soil to Water
MSCC, Residential Soil Cleanup Levels and Industrial/Commercial MSCC from MW-1.
On May 4, 2023, CES returned to the site to collect a perched water sample from MW-1. Prior to
sample collection, depth to groundwater (DTW) measurements were recorded using a water level
meter capable of detecting light non-aqueous phase liquid (LNAPL or Free Product) to an
accuracy of 0.01 feet. Free product was not detected in MW-1. DTW was recorded at a depth of
14.60-feet below grade in MW-1. Groundwater samples were then collected from MW-1, placed
on ice, and delivered under COC procedures to Waypoint on May 5, 2023 for analysis of VOCs
by 6200B, Base/Neutrals and Acids by 625, VPH and EPH by MassDEP methodologies. It should
be noted that due to low water volumes encountered in MW-1, perched water samples were not
submitted for analysis of EDB by 504.1 or Metals (PB & Cr).
Groundwater laboratory analytical results from MW-1 reported the following petroleum-related
constituent concentrations above the 2L Standards:
MW-1: naphthalene, C9-C12 aliphatic and C9-C10 aromatic.
All other concentrations of petroleum-related constituents were reported below 2L Standards from
MW-1.
No concentrations of petroleum-related constituents were reported above the Gross Contaminant
Level (GCL) from MW-1.
Municipal water distribution systems provided by the Town of Sparta serve the subject property
and surrounding properties.
Two water supply wells, located approximately 275-feet to the west of the site at 1467 US-21 S,
and approximately 900-feet to the southeast of the site at 1606 US-21 S, were identified within
1,500-feet of the site during the receptor survey.
CES Project No. 8079.0123E 8
June 5, 2023
Based upon soil concentrations reported above applicable soil standards from a soil sample
collected from immediately above the rock interface, at a depth of approximately 15-feet below
grade, and a perched water sample reporting concentrations above the 2L Standard, but below
the GCL Standard, and with the reported presence of two water supply wells located in the general
vicinity of the site, at a distance of approximately 275-feet to the west (presumed cross gradient)
and 900-feet to the southeast (presumed downgradient), it is recommended that water samples
be collected from these two water supply well systems and analyzed for petroleum-related
constituents to evaluate the potential for the apparent release condition at the subject site to have
impacted these nearby, and identified sensitive receptors.

5.0 RECEPTOR INFORMATION
5.1 Water Supply Wells
As part of this LSA, a water supply well survey was conducted by interviewing the owner of the
subject property, conducting a walking and windshield survey and sending out Request for Water
Supply Well Information forms to property owners located within a 500-feet radius of the subject
property. During the walking and windshield survey, no water supply wells were visually observed
within 500-feet of the site. However, according to information obtained from the subject property
owner, nearby and surrounding property owners, a review of NCDEQ SWAPInfo 2.0 and historical
documents, and the Town of Sparta and Allegany County, two water supply wells, reportedly used
for drinking water, located approximately 275-feet to the west of the site at 1467 US-21 S, and
approximately 900-feet to the southeast of the site at 1606 US-21 S, were identified within 1,500-
feet of the site.
On May 5, 2023, CES sent out Request for Water Supply Well Information forms to the twelve
properties within a 500-feet radius of the subject property. A total of six Water Supply Well
Information forms were returned to CES, or information was otherwise communicated to CES,
which did not report the presence of water supply wells within 500-feet radius of the site, with the
exception of the water supply wells located at 1467 US-21 S and 1606 US-21 S.
Table B-5 summarizes public and private water supply well information.

Not Applicable to the subject site, as the site lies within the Blue Ridge Physiographic Region.
5.6 Subsurface Structures
Underground utilities have been identified at and adjacent to the subject site, and the potential
exists for soil and groundwater contamination to be in contact with these underground utilities.
Perched groundwater has historically been measured at approximately 14-feet below ground
surface at the site. Because the underground utilities are expected to be at a shallower depth
than 14-feet, the utility lines would not be considered receptors or conduits for ground water
contaminant migration. No subsurface structures have been identified at the site.

6.0 LAND USE
6.1 Property Owners and Occupants
Land use in the vicinity of the subject property can be characterized as residential, commercial,
manufacturing and agricultural/farm land uses. Based on petroleum-related constituents reported
above applicable groundwater standards (2L Standard), nearby and surrounding property owners
and occupants may be impacted by the apparent release from Incident Number 7068, should the
contaminant plume happen to extend beyond the subject property. Table B-6 summarizes
contiguous property owners and occupants.
No sensitive land use features, such as schools, daycare centers, nursing homes, hospitals,
playgrounds, churches, camps, or other places of assembly, have been identified within 1,500-
feet of the source of the release, with the exception of Little River, a potential recreation area,
located approximately 1,000-feet to the west of the site. Aerial imagery depicting land use in the
general vicinity of the site is included on Figure 5.

7.0 SITE GEOLOGY AND HYDROGEOLOGY
According to the Geological Map of North Carolina (1985), the subject site is located within the
Blue Ridge Physiographic Province, is underlain by sedimentary and metamorphic rocks of the
Blue Ridge Belt, and is within a muscovite-biotite gneiss formation. A description of the
underlaying Rock Unit Zatm is locally sulfidic; interlayered and gradational with mica schist, minor
amphibolite, and hornblende gneiss.
According to the US Department of Agriculture, Natural Resources Conservation Service, Web
Soil Survey, soils at the subject property consist of Chester loam (CeC), which generally have a
6 to 10 percent slope, and are classified as well drained loam (0 to 5-inches), clay loam (5 to 21-
inches), fine sandy loam (21 to 29-inches) and sandy loam (29 to 80-inches). Parent materials
were classified as creep deposits over residuum weathered from igneous and metamorphic rock.
Encountered soils from monitoring well MW-1A located above the rock interface (0 to 15-feet
below grade) were generally classified as reddish-brown clayey silt.
According to a review of applicable USGS topographic mapping for the subject property and
onsite observations, it has been determined that natural surface drainage in the vicinity of the
subject site is generally in a south-southeasterly direction. While not always the case,
groundwater flow direction typically follows the direction of surface water flow, and is, therefore,
anticipated to flow south-southeasterly. Man-made improvements may alter natural local
drainage patterns to some degree.
The data obtained and reported herein is representative of conditions only at the referenced
boring and monitoring well location, and is not necessarily indicative of conditions elsewhere on
the subject property.

8.0 SAMPLING RESULTS
8.1 Phase I Investigation
Based on the reported rock interface at a depth of approximately 15-feet below grade, on April
25, 2023, under the direction of CES, an air rotary drill rig was mobilized to the site to install one
soil boring in the former gasoline tank grave for subsequent conversion into a 2-inch diameter
permanent groundwater monitoring well to a proposed depth of 35-feet below grade. However,
during drilling activities on April 25, 2023, groundwater was not encountered to a maximum boring
exploration depth of 40-feet below grade utilizing the air rotary drilling equipment. At this time,
per conversations with Mr. Scott Ryals, NCDEQ, the boring was terminated and it was agreed
that an attempt would be made to sample perched water that was observed immediately above
the rock interface at 15-feet below grade. As a result, a 1-inch diameter groundwater monitoring
was set within the bore hole to a depth of 20-feet below grade and completed with 10-feet solid
riser and 10-feet schedule 40 screen.
Soil boring/monitoring well MW-1 was installed by a sub-contracted driller, Carolina Soil
Investigations, LLC of Olin, North Carolina, via air rotary augering techniques, utilizing a track-
mounted geoprobe rig, Model 7822DT, equipped with an air compressor. Prior to the completion
of MW-1, Monitoring Well Construction Permit Number WM0401433 was obtained from the Water
Quality Regional Operations Section of the NCDEQ Division of Water Resources.
Encountered soils from monitoring well MW-1A located above the rock interface (0 to 15-feet
below grade) were generally classified as reddish-brown clayey silt.
Figure 2, Site Plan, depicts the location of monitoring well MW-1. A monitoring well construction
log and drilling form for the soil boring/monitoring well are included as Table B-7 and Appendix
E, respectively. The Monitoring Well Construction Permit and Subsurface Investigation Permit
are included in Appendix E.
During the advancement of the soil boring, the CES Environmental Scientist field screened
encountered soils above the rock interface with a MiniRAE 2000 PID for the presence of VOCs,
reported in parts per million per volume (ppmv), to facilitate the selection of one soil sample for
subsequent laboratory analysis. PID measurements ranged from non-detect (ie, 0.0 ppmv) to
61.5 ppmv, from a soil sample collected immediately above the rock interface, at a depth of
approximately 15-feet below grade.
Based on PID measurements and the presence of the rock interface at approximately 15-feet
below grade, the soil sample immediately above the rock interface, at a depth of approximately
15-feet below grade was collected in laboratory provided vials and glassware, stored on ice, and
hand delivered under COC procedures on April 26, 2023, to Waypoint for laboratory analysis of
the following:
VOCs by 8260 + MTBE/IPE
sVOCS by 8270 BNA
MassDEP VPH
MassDEP EPH
Metals: Pb + Cr
Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil to Water MSCC:
CES Project No. 8079.0123E 20
June 5, 2023
MW-1: 1-methylnaphthalene and 2- methylnaphthalene.
Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil to Water MSCC, Residential Soil Clean Up Levels and the
Industrial/Commercial MSCC:
MW-1: chromium.
All other concentrations of petroleum-related constituents were reported below Soil to Water
MSCC, Residential Soil Cleanup Levels and Industrial/Commercial MSCC from MW-1.
A photographic log depicting the site and soil boring location is included in Appendix B. Figure
2 depicts the location of soil boring/monitoring well MW-1. Figure 3 depicts an Estimated Extent
of Soil Contamination Map. Table B-3 summarizes soil laboratory analytical results. Soil
laboratory analytical reports are included in Appendix D.
On May 4, 2023, CES returned to the site to collect a perched water sample from MW-1. Prior to
sample collection, DTW measurements were recorded using a water level meter capable of
detecting light non-aqueous phase liquid (LNAPL or Free Product) to an accuracy of 0.01 feet.
Free product was not detected in MW-1. DTW was recorded at a depth of 14.60-feet below grade
in MW-1. Groundwater samples were then collected from MW-1, placed on ice, and delivered
under COC procedures to Waypoint on May 5, 2023 for analysis of VOCs by 6200B,
Base/Neutrals and Acids by 625, VPH and EPH by MassDEP methodologies. It should be noted
that due to low water volumes encountered, perched water samples were not submitted for
analysis of EDB by 504.1 or Metals (PB & Cr).
Groundwater laboratory analytical results from MW-1 reported the following petroleum-related
constituent concentrations above the 2L Standards:
MW-1: naphthalene, C9-C12 aliphatic and C9-C10 aromatic.
All other concentrations of petroleum-related constituents were reported below 2L Standards from
MW-1.
No concentrations of petroleum-related constituents were reported above the GCL from MW-1.
Figure 4 depicts a Groundwater Elevation and Estimated Extent of Contamination Map. Tables
B-4 and B-9 summarize groundwater analytical results and depth to groundwater measurements,
respectively. Field data sheets for groundwater sampling, along with CES’ standard operating
procedures for soil and groundwater investigations, and the prepared and reviewed Job Hazard
Analysis (JHA) and Emergency Management and Health & Safety Plan (HASP) are included in
Appendix C. Groundwater analytical reports are included in Appendix D.

9.0 CONCLUSIONS AND RECOMMENDATIONS
9.1 Conclusions and Recommendations
Conclusions:
A Phase I LSA of the subject property was completed by CES to evaluate if soil and groundwater
has been impacted at the site by the apparent release condition from the historical operation of
the gasoline UST system (removed in December, 1990), and if the potential exists for nearby
water supply wells and/or other receptors to be impacted.
Subsequent findings indicated that a soil sample collected from a soil boring/monitoring well (MW-
1) installed in the area of the former gasoline tank grave, reported concentrations of petroleum-
related constituents above Soil Standards, and subsequent groundwater samples collected from
MW-1 reported concentrations of petroleum-related constituents above 2L Standards, but below
the GCL.
Two water supply wells, used for drinking water, located approximately 275-feet to the west of the
site at 1467 US-21 S, and approximately 900-feet to the southeast of the site at 1606 US-21 S,
were identified within 1,500-feet of the site.
Recommendations:
Based upon soil concentrations reported above applicable soil standards from a soil sample
collected from immediately above the rock interface, at a depth of approximately 15-feet below
grade, and a perched water sample reporting concentrations above the 2L Standard, but below
the GCL Standard, and with the reported presence of two water supply wells located in the general
vicinity of the site, at a distance of approximately 275-feet to the west (presumed cross gradient)
and 900-feet to the southeast (presumed downgradient), it is recommended that water samples
be collected from these two water supply well systems and analyzed for petroleum-related
constituents to evaluate the potential for the apparent release condition at the subject site to have
impacted these nearby, and identified sensitive receptors.

ENVIRONMENTAL MANAGEMENT AND HEALTH AND SAFETY PLAN (EMP)
NCDEQ Project WS-2851_7068
G&B Oil Company
1497 NC 21 S
Sparta, Alleghany County, NC
1.0 INTRODUCTION
This Environmental Management and Health and Safety Plan (EMP), additionally referred to
as the ‘plan”, has been developed for CES Group Engineers, LLP (CES), for application to
work completed at NCDEQ WS-2851_7068, G&B Oil Company, 1497 N C 21 S, Sparta,
Alleghany County, North Carolina, under CES Project Number: 8079.0123E. For the purpose
of this plan, the term “project” references “NCDEQ WS-2851_7068”. Additionally, this plan
should also be utilized for any work completed at surrounding properties where
contamination, or additional assessment activities, may be located. For the purpose of this
plan, the term “subsurface investigation” will include, but is not limited to, geophysical
investigations, air rotary drilling of soil borings with conversion to temporary or permanent
monitoring wells, excavation and removal of encountered underground storage tanks (USTs),
and contaminated soils / groundwater, and additional assessment and remediation activities,
which may include hand-augering of soil borings, installation of monitoring wells and/or
remedial recovery wells, groundwater monitoring and sampling, and injections, and the
abandonment of monitoring wells. The term “subsurface investigation” may also be referred
to as “excavation” in this plan. The plan addresses health and safety procedures and
information relevant to environmental services being provided by CES personnel, and/or
subcontracted personnel. The health and safety portion of the plan provides procedures to
minimize: (1) the potential for accidents from physical hazards, and (2) the potential for
exposure to chemical contaminants during activities which disturb the subsurface materials
in the event that contamination of soil or groundwater by special wastes is encountered. The
Project Manager, assisted by the assigned Site Safety officer, will ensure that all on-site
subcontractor personnel, and site visitors, comply with the specified health and safety
requirements. At least one copy of this EMP will be maintained at the local office of CES, as
well as one copy will be maintained onsite by CES, and/or subcontracted personnel.
2
As part of CES’ safety program, a site-specific Job Hazard Analysis (JHA) form will be used,
in conjunction with this plan, which will also include the name, address, and telephone
number of the nearest hospital in relation to the project address where work is being
completed. CES personnel have been instructed to utilize 911 as the first call should an
accident, or issue, be apparent that warrants an immediate emergency response action. This
plan is intended for general use during subsurface investigation activities completed by CES
personnel, or CES subconsultants/subcontractors, and as a general reference for workers to
review and understand the potential environmental and health and safety conditions that may
be present under normal subsurface investigation conditions. Additionally, this plan should
also be utilized for any work completed at surrounding properties where subsurface
investigation activities are, or may be required.
Prior to initiating subsurface investigation activities, as those referenced above, CES
personnel (Project Manager(s), Site Safety Officer, and/or Field Crews) will complete Job
Hazard Analysis (JHA) and selected CES safety forms which detail job specifics, including
the sequence of basic job steps, potential incidents or hazards, and recommended
procedures to eliminate potential incidents or hazards.
1.1 PURPOSE / OBJECTIVE
The protection of workers and environmental safety and health are major concerns during
this project and cannot be understated. The objective of the EMP is to document procedures
and precautions to be implemented during any geophysical investigations and installation of
soil borings (via air rotary drilling techniques) with conversion to permanent monitoring wells,
and site assessments, including soil and groundwater monitoring and/or remediation
activities, in order to provide for and promote safe working conditions at the site during field
activities, specifically at locations where contamination of soil and groundwater has been
documented and/or is expected to be encountered. The safety organization and procedures
have been established based on a previous analysis of potential hazards at the site. Personal
protection measures have been selected in response to these potential hazards.
This EMP and HASP has also been developed based upon review of the requirements
described in the U.S. Environmental Protection Agency (USEPA) Standard Operating Safety
Guide and the U.S. Department of Labor OSHA standards 29 CFR Part 1910. Reasonable
precautions will be taken by the contractor’s representative and its subcontractors to provide
for and promote the safety and health of workers and the general public. Subcontractors will
3
be given copies and will be required to follow this EMP.
1.2 RESPONSIBILITIES FOR HEALTH AND SAFETY
All site activities which have the potential to expose personnel to site contamination or a
related injury are subject to this EMP. Personnel will be responsible for adherence to the
safety procedures during the performance of the work. In no case may work be performed
in a manner that conflicts with the intent of, or the inherent safety and environmental cautions
expressed in, these procedures. Following due warning(s), personnel who violate safety
procedures will be dismissed from the site, and may be terminated. In the event that
contamination is encountered during regular construction operations, personnel will be
exclusively employed in the affected area of the project site, who have been properly trained
in health and safety regulations associated with handling hazardous materials or special
wastes as specified in the training section (Section 9.0) of this EMP.
The requirements provided herein may be modified as the work progresses to accommodate
changing conditions, but a reduction or increase in the health and safety requirements will
not be made without prior approval by the assigned Site Safety Officer (SSO). The prevention
of adverse health effects and injuries to site workers is totally dependent on the contribution
of all project participants. Open communication among workers, supervisors, and
management concerning safety at the site is an essential element of this EMP.
1.3 SUBCONTRACTOR’S RESPONSIBILITY
The Subcontractor is solely responsible for the health, safety, and protection of their own on-
site personnel during the performance of the survey services work scope. The Subcontractor
will perform the work specified in the contract documents in accordance with the HEALTH
AND SAFETY REQUIREMENTS specified herein, and federal, OSHA, state, and local health
and safety regulations. It will be the responsibility of the Subcontractor to be familiar with the
required health and safety regulations in the performance of this work. The Subcontractor
will designate a Site Safety officer to implement and monitor activities related to this EMP.
Should any unforeseen or site-specific safety-related factor, hazard, or condition become
evident during the performance of the work, the Subcontractor will take immediate and
prudent action to establish and maintain safe working conditions and to safeguard site
personnel, the public, and the environment.
4
2.0 ASSIGNMENT OF RESPONSIBILITY
All site activities which have the potential to expose CES personnel to site contamination or
related injury are subject to this EMP. As previously discussed, all site personnel are
responsible for adherence to the safety procedures during performance of the work. Specific
oversight responsibilities are assigned to various personnel as discussed in the paragraphs
to follow.
2.1 SITE SAFETY OFFICER
The SSO will be assigned to monitor the daily activities to assure that all health and safety
procedures/policies are being followed by CES personnel. This includes communicating the
specific requirements to all personnel, including subcontractors, implementing the EMP,
conducting site inspections to monitor compliance with EMP as required, providing or
coordinating training as required, coordinating the medical monitoring program, coordinating
respirator fit tests as required, coordinating the acquisition, calibration and maintenance of
air monitoring equipment, respirators and other safety equipment, directing on-site health and
safety activities, and reporting safety related incidents or accidents to the Project Manager.

3.0 BACKGROUND AND HAZARD EVALUATION
3.1 PROJECT DESCRIPTION
This project involves the installation of monitoring well(s) via air rotary drilling techniques with
the subsequent monitoring of potentially contaminated groundwater with petroleum related
constituents, and may also include geophysical investigations or utility clearance, and the
installation of future soil borings with conversion to permanent monitoring wells via
mechanical drilling techniques (ie, air rotary), and potential future assessment, monitoring
and remediation of soil and groundwater contaminants potentially encountered by said or
existing borings. Future activities at the site may include, but are not limited to excavation
and removal of encountered underground storage tanks (USTs), and contaminated soils /
groundwater, and additional assessment and remediation activities, which may include hand-
augering of soil borings, installation of permanent monitoring wells and/or remedial recovery
wells, groundwater monitoring, and injections, and abandonment of monitoring wells. During
the completion of the aforementioned activities, heavy equipment and machinery, such as
drilling rigs, compressors, excavators, back-hoes, dump trucks, etc may be utilized and
present onsite.
3.2 HAZARD EVALUATION
Constant attention will be given to physical hazards encountered during work day activities,
particularly those activities associated near heavy equipment such as drilling, subsurface
6
excavations, and/or earthmoving equipment. An evaluation of the potential hazards
associated with site activities has been completed by reviewing the general construction
scope of work for each of the projects, to be performed by others. The following potential
exposure pathways have been identified:
· Dermal contact, inhalation and ingestion of contaminated soils and
groundwater
· Inhalation and ingestion of contaminated vapors and particles
· Ingestion of waste solids (accidental/poor hygiene)
· Dermal contact with waste solids
Given that subsurface investigation activities may occur in close proximity to ongoing or future
construction (ie, excavations) related activities that may disturb surficial and subsurface soils,
pipes, etc and the physical properties of the contaminants that may be present at these
locations, there is a potential respiratory hazard from contaminants such as petroleum related
compounds, and therefore a contact hazard from petroleum related compounds. A
respiratory hazard from dust and contaminated dust particles may also exist during nearby
drilling, excavation and removal activities.
It is recognized that site hazard evaluation is a dynamic and on-going process that changes
on a daily basis during progression of the work. However, significant deviation from the
prescribed site characterization will necessitate re-evaluation and possible EMP revision.
Communication from the SSO will initiate the re-evaluation process by the Project Manager.
3.3 SAFETY DATA SHEETS (SDS)
Consistent with 29 CFS 1910.1200, (Hazard Communication Standard) applicable Safety
Data Sheets (or equivalent) will be kept on-site, in each vehicle, and with the Project
Manager. All subcontractors must ensure that their employees are informed of their rights
and responsibilities under the OSHA Hazard Communication Standard. Subcontractors will
provide SDS sheets for items which they bring on the site, as applicable. Due to the presence
of petroleum related constituents, a SDS for Benzene (prepared by Marathon Petroleum
Company, dated 5/14/2015), as VOC concentrations may be encountered onsite, has been
included as Appendix A. It should be noted that the attached SDS is representative of
potential chemicals and materials that may be encountered in the field during subsurface
investigation activities. Should these, or any other chemicals or hazardous materials, actually
7
be encountered by CES employees while in the field, the hazards and exposures of these
chemicals or hazardous materials will be re-evaluated.
4.0 AIR MONITORING
The purpose of air monitoring during subsurface investigation activities is to identify and
quantify airborne contaminants to determine the level of protection needed. Should air
monitoring for airborne contaminants be necessary, air monitoring with direct reading
instruments will be conducted during all intrusive activities. Four categories of air monitoring
will be conducted as follows:
· Breathing Zone Monitoring
· Explosive Gas Source Monitoring
· Work Area Monitoring
· Dust Monitoring
Equipment to be used in conducting air monitoring activities, along with a description of the
type and frequency of monitoring and associated action levels are discussed in the
paragraphs to follow. It should be noted that the contractors working in active construction
zones, including but not limited to excavations, trenches, bore holes, etc should be
responsible for proper air monitoring of these areas. However, should CES feel the need to
perform additional air monitoring, the following procedures (as outlined in sections 4.0
through 6.0, and to an extent, sections 7.0 through 11.0) may be implemented.
4.1 MONITORING EQUIPMENT
If CES employees are working in, or near, active construction zones where the potential
exists for chemical hazards and exposures to be present, the breathing zones will be
monitored using a MiniRAE portable VOC monitor. These instruments use a photoionization
detector that is designed to measure trace quantities of VOCs with a parts-per-million (ppm)
sensitivity range. It does not detect methane. The survey instrument will be calibrated using
an appropriate standard according to manufacturer’s instructions. The VOC monitor will be
calibrated prior to each use if the instrument is used infrequently, or daily when in constant
use.
If the MiniRAE portable VOC monitor detects elevated levels of VOC concentrations (> 50
ppmv), in ambient air at the site, a Gastech 02 /explosion/H2S meter will be used to measure
oxygen concentrations, explosion potential, and hydrogen sulfide (H2S) concentration. The
8
instrument will be calibrated with methane and H2S according to the manufacturer’s
instructions.
Air monitoring equipment will be certified intrinsically safe and operated by personnel trained
in the use of the specific equipment provided.
4.2 TYPES AND FREQUENCY OF MONITORING
4.2.1 Breathing Zone Monitoring
The breathing zone of a representative employee suspected of greatest exposure for each
job category engaged in work with potentially hazardous substances will be monitored as
follows:
· For excavation operations, monitor the breathing zone of the
equipment operator and laborers with an OVM when the waste
material is initially exposed. The results of the monitoring, the
employee’s name, and the work activity will be recorded in the
daily log
4.2.2 Explosive Gas Source Monitoring
During all operations identified as having a fire/explosion hazard, a combustible gas meter
set to measure the lower explosive level (LEL) will be used to continuously monitor the top of
the trench or excavation.
4.2.3 Work Area Monitoring
Each work area associated with hazardous waste spills and/or contamination will be
monitored at least one time each day with an OVM to determine the concentration of
contaminants being released into the general area.
4.2.4 Dust Monitoring
Chemical exposure via inhalation will be mitigated through the evaluation of wind velocity,
and common sense. Personal protective equipment will be utilized as necessary (based on
specific action levels) to prevent chemical exposure in excess of the exposure limits.
When possible, personnel should be situated upwind of work activity when working at the
site. Excavated areas should be allowed to vent for one to two minutes prior to investigative
9
activities to allow any vapors, dusts, or gases to dissipate. Liquids and solids should never
be smelled to confirm the presence or absence of chemicals.
The SSO or CES representative will screen the site for dusty conditions to prevent inhalation
of chemicals in particulate form (e.g. residue on soil grains). If dusty conditions are observed,
all workers will wear appropriate respiratory protection designed for dusts. Extremely dusty
conditions may require dust suppression via water mist or spray prior to returning to work.
4.3 ACTION LEVELS
The action levels as prescribed by the National Institute for Occupational Safety and Health
(NIOSH) will be used to initiate protective actions including, but not limited to, use of personal
protective devices, shut down of specific work activities, and site evacuation. A current
volume of the NIOSH Pocket Guide (electronic version) to Chemical hazards will, or may be
utilized as an on-site referenced by the SSO.
5.0 PERSONAL PROTECTIVE EQUIPMENT AND PROCEDURES
5.1 RESPIRATORY PROTECTION
During excavation or construction activities in an area where special wastes are expected or
have been encountered, the use of respiratory protection equipment may be required.
Respiratory protection is of primary importance as inhalation is one of the major routes of
exposure to chemical toxicants. Respiratory protective devices include air purifying
respirators, air-line respirators, and self-contained breathing apparatus.
The following respiratory protection practices will be observed by all workers at the Site when
conditions warrant respiratory protection:
· The respiratory protection utilized on-site will be in accordance
with OSHA, 29 CFR 1910.134
· Only properly cleaned, maintained, NIOSH/MSHA-approved,
respirators will be used on-site (if required)
· Selection of respirators, as well as any decisions regarding
upgrading or downgrading of respiratory protection, will be
10
made by the SSO
· Air-purifying cartridges will be replaced on a regular basis (at
least once per day) as determined by the SSO
· No employee will be assigned to tasks requiring the use of
respirators if, based upon the most recent examination, a
physician determines that the employee will be unable to
function normally wearing a respirator or that the safety or
health of the employee or other employees will be
compromised by use of a respirator
· Persons required to wear full-face respirators must not have
beards or moustaches that interfere with proper respirator seal.
All personnel wearing full-face respirators or personnel working
in the exclusion zone will be required to be clean-shaven prior
to each day’s shift. This will be strictly enforced by the SSO
· All personnel required to use APRs must be properly fit tested
prior to engaging in field activities in accordance with OSHA
standards (29 CFR 1910.1025)
5.2 PROTECTIVE CLOTHING
To protect workers against dermal contact with contaminants, the following apparel must be
worn during site-specific work activities depending on the level of protection specified for
those activities (Section 5.3 of this EMP):
· Disposable Tyvek coveralls
· PVC-coated or equivalent coveralls for splash protection
· Nitrile gloves or equivalent
· Inner gloves - latex or vinyl
· Outer disposable boots
· Hard hat
· Chemical-resistant boots (Neoprene, PVC, or equivalent)
11
· Hearing protection (as applicable)
· Steel-toed safety shoes
· Goggles or safety glasses will be worn at all times in the work area
· Sleeves taped to gloves and cuffs taped to boots
· Face shield attachments for use with hard hats
· Disposable, chemical-resistant outer boots
Upgrading or downgrading selected protective equipment will be the decision of the SSO
based on assessment of exposure potential during specific tasks.
5.3 LEVELS OF PROTECTION
The levels of protection to be utilized at the site, and the activities to which they apply, are
described in the following paragraphs. The SSO will select the appropriate level of PPE
based on air monitoring results.
5.3.1 Modified Level D
This is the minimum level of protective clothing to be worn at the site during subsurface
investigation activities. All workers, supervisors, and visitors will be required to don the
following clothing prior to entering the project site. Based on the anticipated activities to be
performed at the site, it is anticipated that Modified Level D will provide adequate protection
coverage.
· Work clothes
· Hard hat
· Safety shoes
· Visibility vest
· Work gloves (only as necessary)

· Hearing protection (as determined by SSO)
5.3.4 Level B Protection
Level B will be used for site work when inhalation and dermal contact hazard are elevated to
the point that a positive pressure, supplied air source is needed.
· Saranex coveralls/chemical-resistant clothing
· Gloves (inner latex gloves and outer nitrile gloves)
· Hard hat
· Self-contained breathing apparatus (SCBA), or Supplied Air-
Line Respirator (SAR)
· Chemical-resistant safety boots
· Gloves and boots taped to prevent leakage
13
6.0 SITE CONTROL
The purpose of site control is to minimize potential contamination of workers and to protect
the surrounding area from hazards found at the site. If the project site is not secured by
fencing or other suitable site control means and is not routinely patrolled by police or other
independent security personnel; certain procedures must be followed to ensure suitable site
control and limitation of access so that those persons who may be unaware of site conditions
are not exposed to hazards.
All excavations left open and unattended by site personnel will be appropriately barricaded
and visibly posted with “No Trespassing” or other appropriate signage. All heavy machinery
and equipment shall be locked or chained each evening upon completion of daily activities.
All potentially contaminated media, such as soil, will be covered with plastic prior to leaving
the site.
6.1 REGULATED AREAS
As appropriate to the task conducted, the site vicinity will be divided into three zones to allow
control of worker exposures. These zones are described as follows:
· Exclusion Zone. This zone includes the actual area of
contamination and localized work area where specific
investigative and/or construction equipment is operating. This
zone has the highest inhalation exposure potential, and/or
presents a high probability of skin contact with cutaneous
percutaneous - affecting chemicals. New exclusion zones
may exist during certain site-specific activities. This will be
defined by the SSO and access by individuals not necessary
to operation will be limited. (Level D is minimum).
· Contamination Reduction Zone. This zone includes the areas
immediately surrounding the Exclusion Zone. All personnel
and equipment leaving the Exclusion Zone shall be
decontaminated in this zone.
14
Support Zone. This zone covers all areas outside of the
Contamination Reduction Zone. Administrative activities are
conducted in the Support zone, as well as equipment supply
and first aid supply. It is essential that contamination be kept
out of this zone.
6.2 ACCESS/SITE SECURITY
Access to contaminated work areas (Exclusion and Contamination Reduction Zones) will be
regulated and limited to authorized persons. Such persons include the Contractor’s
employees, designated equipment operators, and designated union representatives, as
applicable. The SSO will enforce access limitations during work hours.
6.3 POSTING/BARRICADES
Warning signs will be posted and hung, as applicable, in readily visible locations in or near
contaminated work areas. Barricades or barricade tape will be utilized to prevent access to
various work areas as indicated above.
7.0 POLICIES
7.1 GENERAL WORK PRACTICES
General work practices to be employed on-site are as follows:
· At least one copy of this EMP will be available at the work site

exclusion or contamination reduction zones. No tobacco
products will be present or used, and cosmetics will not be
applied in the exclusion or contamination reduction zones
· No matches or lighters are permitted in the exclusion or
contamination reduction zones
· During operations within an area of contamination, all
employees will be required to wash their hands and face before
eating, drinking, smoking, or applying cosmetics
15
· Field personnel must observe each other for signs of exposure.
Indications of adverse effects include, but are not limited to, the
following:
- Changes in complexion and skin
discoloration

· Establish hand signal communication when verbal
communication is difficult. Select one person per work group
to be the one to give hand signals to equipment operators
· Be aware of footing at all times
· Be sure that all heavy equipment has a backup alarm
· Be sure that only qualified people operate heavy equipment
· Use chains, hoists, straps, and other equipment to safely move
heavy materials
· Use proper personal lifting techniques. (Use your legs, not your
back)
· Never walk directly in back of, or to the side of, heavy
equipment without the operator’s knowledge
· Never use a piece of equipment unless you are familiar with its
operation. This applies to heavy as well as light equipment (for
example, chain saws)
· Make sure all precautions have been taken before moving pipe
sections and other materials to be utilized during this project as
they are extremely heavy. Let the equipment, not your body,
do the moving
17
· Be sure that no underground or overhead power lines, sewer
lines, gas lines, or telephone lines will present a hazard in the
work area
7.3 SANITATION
Onsite sanitation facilities (e.g., wash stations, etc.) may be provided for use by field
personnel assigned to the work if work activities involve the direct handling of contaminated
soils and groundwater.
8.0 DECONTAMINATION
The process of removing or neutralizing contaminants that have accumulated on personnel
and equipment is critical to personnel protection. Decontamination protects workers from
hazardous substances that may contaminate and eventually permeate the protective
clothing, respiratory equipment, tools, vehicles, and other equipment used on site.
Decontamination protects site personnel in the following ways: minimizing the transfer of
harmful materials into clean areas; preventing the mixing of incompatible chemicals; and
protecting the community by preventing uncontrolled transportation of contaminants from the
site.
General – Each time an employee enters the Contamination Reduction Zone from the
Exclusion Zone, he/she just make a thorough self-examination. Equipment must be removed
without exposure to the wearer. Hands and face must be scrubbed before eating or use of
tobacco or cosmetic products to avoid accidental ingestion of wastes. Footwear must be
changed prior to leaving the Contamination Reduction Zone to avoid “tracking” of
contaminants outside the area.
Clothing – The Contractor will provide all required protective clothing. Protective clothes will
be left in the change facility. No clothing (including boots) is to be worn or carried away from
the site. Soiled clothing is to be disposed of as appropriate.
Respirators – All required respirators will be provided and maintained by the Contractor and
will be cleaned daily. Cleaning and maintenance will be performed in accordance with the
appropriate OSHA standard (29 CFR 1910.134).
18
Packaging of Waste Items – All disposable clothing and other contaminated material will be
placed in containers for storage on-site. Personnel will make a conscious effort to minimize
the volume of contaminated materials. Legible and understandable precautionary labels will
be affixed prominently to containers of contaminated scrap, waste, debris, and clothing.
Containers will be disposed with other solids in an EPA-approved manner.
8.1 PERSONAL DECONTAMINATION
Minimum measures to be undertaken for decontamination are outlined below. These
measures are to be followed, as applicable, unless the SSO specifies that a higher level of
decontamination is warranted, and accordingly, sets forth upgraded decontamination
procedures.
MINIMUM MEASURES FOR DECONTAMINATION
STATION PROCEDURES
1. Equipment Drop 1. Deposit equipment used on site (tools, sampling
devices and containers, monitoring instruments, radios,
clipboards, etc.) on plastic drop cloths or in different

10.0 HEALTH MONITORING
10.1 PHYSICAL EXAMINATION
The Contractor may require all of its field workers to pass a pre-employment medical
examination prior to working at the site. The examination shall include a complete medical
and occupational history, and an evaluation from the attending physician as to whether the
employee is qualified to work in areas where exposure to chemicals or physical stress is
possible, and is physically able to use protective equipment, including respirators.
10.2 HEAT STRESS
Subsurface investigation tasks, assignments, projects etc will, or may be conducted during
all four season, winter, spring, summer and fall. Accordingly, warm temperatures during
these time periods may put extra physical stress on the body. Long periods of exposure to
heat may cause illness, particularly if the employee is not accustomed to working in hot areas.
Also, heat builds up inside protective clothing, so there is a risk of heat stress even if outside
temperatures are moderate.
The signs, symptoms and treatment of heat stress are outlined below. All individuals
participating in work in the Exclusion Zone and Contamination Reduction Zones should be
monitored regularly for heat stress symptoms.
Heat Cramps
Symptoms: painful muscle spasms
Cause: profuse sweating and drinking large amounts of water
Treatment: provide liquids with electrolytes (sodium, potassium) like diluted
Gatorade
22
Heat Exhaustion
Symptoms: weakness, fatigue, dizziness; pale, cool, moist skin; heavy sweating;
Headache; nausea; and fainting
Cause: reduced blood volume resulting from dehydration from profuse
sweating and insufficient replacement of water and salts
Treatment: If worker is conscious, rest in cool place; replace water and electrolytes
lost in sweat; if unconscious, get medical help immediately. DO NOT
give liquids if person is unconscious
Heat Stroke
Symptoms: very dry, hot skin with red mottled or bluish appearance; confusion;
Convulsions; unconsciousness; rapidly rising temperature
Cause: body becomes overheated because the worker does not sweat.
Can be fatal.
Treatment: call for medical help immediately; move person to cool place;
remove PPE; use wet towels or water and fan to cool while waiting
for help.
10.4 COLD STRESS
Subsurface investigation tasks, assignments, projects etc will, or may be conducted during
all four season, winter, spring, summer and fall. Accordingly, cold temperatures during these
time periods may put extra physical stress on the body. Long periods of exposure to cold
may cause illness, particularly if the employee is not accustomed to working in cold areas.
Cold stress occurs by driving down the body’s skin temperature and eventually the body
temperature (core temperature).
The signs, symptoms and treatment of cold stress are outlined below. All individuals
participating in work in the Exclusion Zone and Contamination Reduction Zones should be
monitored regularly for cold stress symptoms.
23
Hypothermia:
Symptoms: shivering, reduced circulation, slow/weak pulse, slowed breathing, lack
of coordination, irritability, confusion, sleepy behavior
Cause: body heat is lost faster than it can be replaced and normal body
temperature drops below 95 degrees F
Treatment: move person to warm and dry area, remove wet clothes and replace
with dry clothes, layer with blankets, give warm sweetened liquids, if
unconscious, get medical help immediately. DO NOT give liquids if
person is unconscious
Frostbite
Symptoms: reddened skin, with development of gray/white patches, numbness,
firm or hard parts affected, blisters
Cause: freezing of skin and underlying tissues typically affecting extremities,
particularly the feet and hands
Treatment: move person to warm and dry area, remove wet clothes and replace
with dry clothes, layer with blankets, give warm sweetened liquids, if
unconscious, get medical help immediately. DO NOT give liquids if
person is unconscious. DO NOT rub affected area, DO NOT break
blisters, DO NOT try to directly warm the frostbite areas without
medical attention
Trench Foot
Symptoms: redness of skin, swelling, numbness, blisters
Cause: prolonged exposure to wet and cold temperatures, constantly wet and
cold feet, wet and cold feet lose heat 25x faster than dry feet
Treatment: call for medical help immediately; remove the shoes, boots, wet
socks, dry the feet
24
10.5 SELF MONITORING
While at the site, CES employees and sub-contractors will be required to monitor their own
health and that of their co-workers. Visual observations include:
- behavioral changes
- change in appetite
- coordination losses
- gum and lip discoloration
- increased salivation
- pupil dilation
- sensation losses
- skin rashes
- slurred speech
Any abnormalities or changes are to be reported to the physician and investigated
immediately. Such aspects could be symptoms of toxic exposure and must not be allowed to
persist without medical attention. In addition, all accidents and injuries, no matter how small,
are to be reported to the SSO and investigated.
11.0 SITE STANDARD OPERATING PROCEDURES
11.1 WORK PRACTICES
The need to exercise caution in the performance of specific work tasks is made more acute
due to weather conditions, restricted mobility, and reduced peripheral vision caused by the
protective gear itself, the need to maintain the integrity of the protective gear, and the
increased difficulty in communicating caused by respirators. Work at the site will be
conducted according to established procedures and guidelines for the safety and health of
all involved. Among the most important of these principles for working at the site are:
- In any unknown situation, always assume the worst conditions and plan
accordingly
- Establish and maintain communication
25
- Minimize contact with excavated or contaminated materials. Plan work
work areas, decontamination areas, and procedures to accomplish this.
Do not place equipment on drums or on the ground. Do not sit or stand
on drums or other materials
- Employ disposable items when possible to minimize risks during
decontamination and possible cross-contamination during
sampling/handling.
This will require a common-sense approach to potential risks and costs
- Smoking, eating, or drinking after entering the work zone and before
decontamination will not be allowed. Oral ingestion of contaminants from
your hands are a likely means of introduction of the toxic substances into the
body
- Avoid heat and other work stresses relating to wearing the protective gear.
Work breaks and proper tracking are planned to prevent stress-related
accidents or fatigue
- Maintain monitoring systems. Conditions can change quickly if sub-surface
areas of contamination are penetrated
- Be observant of not only your own immediate surroundings but also that of
others. It is a team effort to notice and warn of impending dangerous
situations. Extra precautions are necessary when working near heavy
equipment while utilizing personal protective gear, as vision, hearing, and
communication may be restricted by the protective gear
- Be aware that chemical contaminants may aggravate or worsen symptoms
of other illnesses or intoxication. Avoid use of alcohol and working when ill
11.2 COMMUNICATION PROCEDURES
Personnel in the Exclusion Zone shall remain within sight of other project personnel, and
should work in conjunction with another individual. Since it is not anticipated that the project
area will encompass a large area at any given time, radio communication will not be required.
26
The following standard hand signals will be used in the event that communication is required
amongst workers in and/or between the Exclusion Zone and Contamination Reduction Zone.
Hand gripping throat Out of air, cannot breathe
Grip partner’s wrist, or both Leave area immediately
Hands around partner’s waist
Rotating hands above the head Need assistance
Right hand thumb up OK, I’m all right, I understand
Right hand thumb down No, negative
12.0 EMERGENCY PROCEDURES
12.1 GENERAL
A comprehensive emergency response plan has been developed to handle all on-site
emergencies. A list of site conditions which might require implementation of the plan includes
but is not limited to:
- Fire or explosion on-site

12.4 PERSONNEL INJURY IN THE EXCLUSION ZONE
When there is an injury in the Exclusion Zone, a continuous horn blast will be sounded as an
emergency signal (as applicable). Upon the sounding of the emergency signal, all site
personnel shall assemble in the personnel decontamination area. Rescue personnel will
enter the Exclusion Zone (if required) to remove the injured person. The SSO, or CES
representative, will evaluate the nature of the injury and call for an ambulance (if needed),
and the affected person will be decontaminated to the extent possible prior to movement to
the Support Zone. The appropriate first aid will be administered. No persons shall re-enter
the Exclusion Zone until the cause of the injury or symptom is determined.
12.5 PERSONAL INJURY IN THE SUPPORT ZONE
Upon notification of an injury in the Support Zone, the SSO, or CES representative, will
assess the nature of the injury. If the injury or absence of the injured person does not affect
the performance of site personnel, operations may continue while appropriate first aid and
follow-up is initiated. If the injury increases the risk to others, the designated emergency
signal (continuous horn blast) shall be sounded, and all site personnel shall move to the
decontamination line for further instructions. Activities on-site will stop until the added risk is
removed or minimized.
12.6 FIRE OR EXPLOSION
Upon notification of a fire or explosion on-site, a continuous horn blast will be sounded, and
all site personnel will assemble at the decontamination area. The fire department must be
alerted and all personnel moved as soon as possible to a safe distance.
12.7 PERSONAL PROTECTIVE EQUIPMENT FAILURE
If any site worker experiences a failure or alteration of protective equipment which may alter
the protection factor, that person and his/her work partner must immediately leave the
Exclusion Zone. Re-entry shall not be permitted until the equipment has been appropriately
repaired or replaced.
12.8 POLLUTANT DISCHARGES/SPILLS
In the event of an unauthorized discharge of pollutants or contaminants into the soil, sewers, or
ambient air, the person first finding such an incident should immediately notify the Project
Manager and/or the SSO. The Project Manager and/or SSO will immediately notify Greg Hans

4. FIRST AID MEASURES
First Aid Measures
General Advice:In case of accident or if you feel unwell, seek medical advice immediately (show directions
for use or safety data sheet if possible).
Inhalation:Remove to fresh air. If not breathing, institute rescue breathing. If breathing is difficult,
ensure airway is clear, give oxygen and continue to monitor. If heart has stopped,
immediately begin cardiopulmonary resuscitation (CPR). Keep affected person warm and at
rest. GET IMMEDIATE MEDICAL ATTENTION.
Skin Contact:Immediately wash exposed skin with plenty of soap and water while removing contaminated
clothing and shoes. May be absorbed through the skin in harmful amounts. Get medical
attention if irritation persists.
Place contaminated clothing in closed container until cleaned or discarded. If clothing is to
be laundered, inform the person performing the operation of contaminant's hazardous
properties. Destroy contaminated, non-chemical resistant footwear.
Eye Contact:Flush immediately with large amounts of water for at least 15 minutes. Eyelids should be
held away from the eyeball to ensure thorough rinsing. Gently remove contacts while
flushing. Get medical attention if irritation persists.
Ingestion:Do not induce vomiting because of danger of aspirating liquid into lungs, causing serious
damage and chemical pneumonitis. If spontaneous vomiting occurs, keep head below hips,
or if patient is lying down, turn body and head to side to prevent aspiration and monitor for
breathing difficulty. Never give anything by mouth to an unconscious person. Keep affected
person warm and at rest. GET IMMEDIATE MEDICAL ATTENTION.
Most important signs and symptoms, both short-term and delayed with overexposure
Adverse Effects:Overexposure to vapors may cause eye, skin and respiratory irritation. Headache,
drowsiness, dizziness, loss of coordination, disorientation and fatigue. Prolonged and
repeated contact may cause defatting and drying of the skin and may lead to irritation
and/or dermatitis. Prolonged or repeated exposure may cause adverse effects on blood,
blood-forming organs, and immune system.
Indication of any immediate medical attention and special treatment needed
Notes To Physician:INHALATION: This material (or a component) sensitizes the myocardium to the effects of
sympathomimetic amines. Epinephrine and other sympathomimetic drugs may initiate
cardiac arrhythmias in individuals exposed to this material. Administration of
sympathomimetic drugs should be avoided.
INGESTION: This material represents a significant aspiration and chemical pneumonitis
hazard. Induction of emesis is not recommended.
5. FIRE-FIGHTING MEASURES

Special protective equipment and precautions for firefighters
Firefighters should wear full protective clothing and positive-pressure self-contained breathing apparatus (SCBA) with a full
face-piece, as appropriate. Avoid using straight water streams. Water may be ineffective in extinguishing low flash point fires, but
can be used to cool exposed surfaces. Avoid excessive water spray application. Water spray and foam (AFFF/ATC) must be
applied carefully to avoid frothing and from as far a distance as possible. Keep run-off water out of sewers and water sources.
Additional firefighting tactics
FIRES INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or
monitor nozzles. Cool containers with flooding quantities of water until well after the fire is out. Do not direct water at source of leak
or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of
tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles: if this is
impossible, withdraw from area and let fire burn.
EVACUATION: Consider initial downwind evacuation for at least 1000 feet. If tank, rail car or tank truck is involved in a fire,
ISOLATE for 5280 feet (1 mile) in all directions; also, consider initial evacuation of 5280 feet (1 mile) in all directions.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions:Keep public away. Isolate and evacuate area. Shut off source if safe to do so. Eliminate all
ignition sources.
Protective equipment:Use personal protection measures as recommended in Section 8.
Emergency procedures:Advise authorities and National Response Center (800-424-8802) if the product has
entered a water course or sewer. Notify local health and pollution control agencies, if
appropriate.
Environmental precautions:Avoid release to the environment. Avoid subsoil penetration.
Methods and materials for
containment:
Contain liquid with sand or soil.
Methods and materials for cleaning
up:
Use suitable absorbent materials such as vermiculite, sand, or clay to clean up residual
liquids. Recover and return free product to proper containers. When recovering free liquids
ensure all equipment is grounded and bonded. Use only non-sparking tools.

Hydrocarbons are basically non-conductors of electricity and can become electrostatically
charged during mixing, filtering, pumping at high flow rates or loading and transfer
operations. If this charge reaches a sufficiently high level, sparks can form that may ignite
the vapors of flammable liquids. Sudden release of hot organic chemical vapors or mists
from process equipment operating under elevated temperature and pressure, or sudden
ingress of air into vacuum equipment may result in ignition of vapors or mists without the
presence of obvious ignition sources. Nozzle spouts must be kept in contact with the
containers or tank during the entire filling operation.
Storage Conditions:Store in properly closed containers that are appropriately labeled and in a cool,
well-ventilated area.
Incompatible Materials Strong oxidizing agents.

Personal protective equipment
Eye protection:Use goggles or face-shield if the potential for splashing exists.
Skin and body protection:For non-exposure jobs or where exposure is expected to be less than 15 minutes, neoprene
gloves can be used to prevent skin contact. For all exposure jobs expected to be greater
than 15 minutes, Viton® gloves should be used to prevent skin contact. Glove suitability is
based on workplace conditions and usage. Contact the glove manufacturer for specific
advice on glove selection and breakthrough times. Depending upon the conditions of use
and specific work situations, additional protective equipment and/or clothing may be
required to control exposures.
Respiratory protection:Approved organic vapor chemical cartridge or supplied air respirators should be worn for
exposures to any components exceeding the established exposure limits. Observe
respirator assigned protection factors (APFs) criteria cited in federal OSHA 29 CFR
1910.134. Self-contained breathing apparatus should be used for fire fighting.
Hygiene measures:Handle in accordance with good industrial hygiene and safety practice. Avoid contact with
skin, eyes and clothing.

Delayed and immediate effects as well as chronic effects from short and long-term exposure
BENZENE: Studies of workers exposed to benzene show clear evidence that overexposure
can cause cancer and other diseases of the blood forming organs including Acute
Myelogenous Leukemia (AML), and Aplastic Anemia (AA), an often fatal disease. Some
studies suggest overexposure to benzene may also be associated with Myelodysplastic
Syndrome (MDS). Findings from a case control study of workers exposed to benzene was
reported during the 2009 Benzene Symposium in Munich included an increase in Acute
Myeloid Leukemias and Non-Hodgkins Lymphoid Neoplasms (NHLN) of the subtype
follicular lymphoma (FL) in some occupational categories. Some studies of workers
exposed to benzene have shown an association with increased rates of chromosome
aberrations in circulating lymphocytes. One study of women workers exposed to benzene
suggested a weak association with irregular menstruation. However, other studies of
workers exposed to benzene have not demonstrated clear evidence of an effect on fertility
or reproductive outcome in humans. Benzene can cross the placenta and affect the
developing fetus. Cases of AA have been reported in the offspring of persons severely
overexposed to benzene. Studies in laboratory animals indicate that prolonged, repeated
exposure to high levels of benzene vapor can cause bone marrow suppression and cancer
in multiple organ systems. Studies in laboratory animals show evidence of adverse effects
on male reproductive organs following high levels of exposure but no significant effects on
reproduction have been observed. Embryotoxicity has been reported in studies of
laboratory animals but effects were limited to reduced fetal weight and minor skeletal
variations. Benzene has been classified as a proven human carcinogen by OSHA and a
Group 1 (Carcinogenic to Humans) material by IARC. The current proposed IARC
classification for benzene is summarized as follows: Sufficient evidence for Acute Myeloid
Leukemia; limited evidence for Acute Lymphatic Leukemia, Chronic Lymphatic Leukemia,
Non-Hodgkin Lymphoma, and Multiple Myeloma.
Adverse effects related to the physical, chemical and toxicological characteristics
Signs and Symptoms Overexposure to vapors may cause eye, skin and respiratory irritation. Inhalation of high
vapor concentrations may cause symptoms like headache, dizziness, tiredness, nausea
and vomiting Repeated or prolonged skin contact may cause drying, reddening, itching and
cracking.

625.1 - Base/Neutrals and Acids by GC/MS Method 625.1 Sample 95510 (MW-1) QC Batch No: V33064/V32898
Surrogate(s) were flagged for recoveries in the associated project sample. During the extraction step, the extraction technician noted that a significant emulsion formed. Batch QC samples (Method Blank and Laboratory
Control Samples) all showed surrogate recoveries within QC limits, indicating that the biased recoveries were due to the sample matrix.
Analyte: Benzidine
QC Batch No: V33064/V32898 This target analyte was flagged for recoveries outside QC limits in the associated LCS/LCSD. Data for this
analyte is flagged "M" to indicate that results should be considered minimum concentration due to the potential for a low bias.
Known poor performer. Massachusetts EPH Method MADEP-EPH Sample 95510 (MW-1)
QC Batch No: V33023 Low extraction surrogates. Only received 1 liter for test. Not enough volume for reprep.
Volatile Organic Compounds - GC/MS Method 6200B Analyte: tert-Butyl formate QC Batch No: V33001/V33000
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable.
