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 an underground storage tank (UST
or tank) system (removed in December, 1996), located at the Caldwell County Sheriff’s Office,
214 Mulberry Street, Lenoir, Caldwell 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 has been authorized to perform this LSA 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. No information regarding the
apparent release condition, history, and/or release characterization was made available to CES,
nor is believed to exist for this site. The subject site UST information was retrieved from NCDEQ
UST Incident Map and UST Databases and Reports.

On September 11, 2023, under the direction of CES, one soil boring was installed on the northern
portion of the site in the presumed area of the former UST, dispenser island, and/or product piping,
and was subsequently converted to a 2-inch diameter permanent groundwater monitoring well
(MW-1) to facilitate the collection of soil and groundwater samples for laboratory analysis. Since
no information was available regarding the apparent release condition, history, and/or release
characterization, the placement of MW-1 was determined during the pre-LSA site visit, when an
open-air canopy structure was observed on the northern portion of the site, potentially indicative
of a structure housing a fuel dispenser. Additionally, an in-person inquiry was made during the
pre-LSA site visit with the current site occupant, Caldwell County Sherriff’s Office, and no records
and/or knowledge of the UST location(s) are known to exist, according to interviewed sheriff’s
office personnel.

During the installation of groundwater monitoring well MW-1 on September 11, 2023, one soil
sample was collected above the water table, at a depth of approximately 18-feet below grade,
placed in laboratory provided vials and glassware, stored on ice, and hand delivered under chain-
of-custody (COC) procedures on September 12, 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 MassDEP VPH and EPH.

Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil-to-Water Maximum Soil Contaminant Concentration (MSCC),
Residential Soil Cleanup Levels, and the Industrial/Commercial MSCC:

 MW-1: chromium (50.9 mg/kg).

All other concentrations of petroleum-related constituents in soil were reported below the Soil-to-
Water MSCC, Residential Soil Cleanup Levels, and Industrial/Commercial MSCC from MW-1.

The soil exceedance from MW-1 of the Soil-to-Water MSCC, Residential Soil Cleanup Levels,
and the Industrial/Commercial MSCC for chromium may be related to the elevated concentrations
of native soil. The North Carolina statewide average chromium background level in soil is 32.42
mg/kg according to a published document by Cohan & Yang, 2019.The maximum detected

4
CES Project No. 8195.0823E
November 2, 2023
chromium concentration was 50.9 mg/kg during this Phase I LSA.

Upon completion of the soil boring to a depth of approximately 40-feet below grade, after depth
to groundwater (DTW) was estimated between 23 and 25-feet below grade, and subsequent
conversion to a 2-inch diameter permanent monitoring well (MW-1), 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. A DTW
measurement from MW-1 was recorded at approximately 22.59-feet below grade. Groundwater
samples were then collected from MW-1 in laboratory provided vials and glassware, placed on
ice, and hand delivered under COC procedures to Waypoint on September 12, 2023, for analysis
of VOCs by 6200B, including MTBE, IPE/EDB and 504.1, Base/Neutrals and Acids by 625, Metals
(Pb & Cr), and MassDEP VPH and EPH.

Groundwater laboratory analytical results from MW-1 reported the following petroleum-related
constituent concentrations above the 2L Standards:

 MW-1: chromium (278 ug/l) and lead (22 ug/l).

No concentrations of petroleum-related constituents in groundwater were reported above the
Gross Contaminant Level (GCL).

All other concentrations of petroleum-related constituents in groundwater were reported below 2L
Standards and the GCL from MW-1.

Municipal water distribution systems provided by the City of Lenoir serve the subject property and
surrounding properties.

No water supply wells or/or other receptors were identified within 1,500-feet of the site.

Based upon soil concentrations reported above applicable soil standards, and groundwater
concentrations reported above the 2L Standard, but below the GCL, without the foreseeable risk
of impacting nearby receptors, and without the presence of any known or reported water wells in
the general vicinity of the site, it is of the opinion of CES that the Site Risk/Ranking is Low, and a
Notice of Residual Petroleum (NRP) can be placed on the property.

3.0 SITE HISTORY AND CHARACTERIZATION

The subject site where this LSA was performed, where an apparent release of petroleum-related
constituent occurred, consists of one (1) parcel, identified as Caldwell County Parcel Identification
Number (PIN) 2749872930, and is located at 214 Mulberry Street, as shown on Figure 1.
According to a review of available, and historical documents, the subject property has been owned
by Caldwell County since at least 1952.

This LSA (i.e., the installation of monitoring well MW-1) was performed on the northern portion of
the site in the presumed area of the former 10,000-gallon gasoline UST (removed in December,
1996). A small metal cover, located underneath the canopy structure, presently exists onsite
where the fuel dispenser was presumed to be located prior to its removal. Additionally, an 8,000-
gallon heating oil UST was located at the site and information regarding its history and former
location was not made available to CES, nor was its former location identified during site visits.

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 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.
According to information obtained from the subject property owner, nearby and surrounding
property owners, a review of NCDEQ SWAPInfo 2.0 and the City of Lenoir and Caldwell County
GIS systems, no water supply wells are known to exist within a 1,500-feet radius, as municipal
water distribution systems serve the subject property and surrounding properties.

On October 5, 2023, CES sent out Request for Water Supply Well Information forms to 78
properties within a 500-feet radius of the subject property. A total of 24 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 a 500-feet radius of the site.

Table B-5 summarizes public and private water supply well information.
5.2 Public Water Supplies
According to the NC SWAPInfo 2.0 Map and NC One Map - Public Water Supply Water
Resources Map, no public water supply wells are known to exist within a 1,500-feet radius of the
subject property.

Municipal water distribution systems provided by the City of Lenoir are available to serve the
subject property and surrounding properties.
5.3 Surface Water
According to the NC One Map - Surface Water Classifications Map, Lower Creek is located
approximately 3,900-feet south of the site.

According to the NC One Map - Surface Water Intakes Map, no surface water intakes are located
within a 1,500-foot radius of the subject site.
5.4 Wellhead Protection Areas
According to the NC SWAP website and database of approved North Carolina Wellhead
Protection Areas, no wellhead protection areas and/or approved wellhead protection plans are
known to exist within a 1,500-foot radius of the subject site.
5.5 Deep Aquifers in the Coastal Plain Physiographic Region
Not applicable to the subject site, as the site lies within the Piedmont Physiographic Region.
5.6 Subsurface Structures
Underground utilities have been identified adjacent to the subject site, and the potential exists for
soil and groundwater contamination to be in contact with these underground utilities. Groundwater
has historically been measured at approximately 23-feet below ground surface at the site.

11
CES Project No. 8195.0823E
November 2, 2023
Because the underground utilities are expected to be at a shallower depth than 23-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.

Figure 5 depicts a 1,500-feet Potential Receptor Map.

CES Project No. 8195.0823E
November 2, 2023
6.0 LAND USE
6.1 Property Owners and Occupants
Land use in the vicinity of the subject property can be characterized as commercial, financial,
institutional, and government uses. Based on petroleum-related constituents (chromium and lead
only) reported above applicable groundwater standards (2L Standard), nearby and surrounding
property owners and occupants may be impacted by the apparent release from Incident Number
17199, 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 the First Baptist Church of Lenoir located
approximately 375-feet to the northwest, Caldwell Hospice and Palliative Care located
approximately 720-feet to the northwest, First United Methodist Church located approximately
700-feet to the west, Robins Preschool located approximately 820-feet to the west, the St. James
Episcopal Church located approximately 1,020-feet to the south, Lenoir Presbyterian Church
located approximately 1,200-feet to the northwest, The School For Young Children located
approximately 1,250-feet to the northwest, and Davenport Elementary School located
approximately 1,425-feet to the south.

Aerial imagery depicting land use in the general vicinity of the site is included on Figure 5.

CES Project No. 8195.0823E
November 2, 2023
7.0 SITE GEOLOGY AND HYDROGEOLOGY

According to the Geological Map of North Carolina (1985), the subject site is located within the
Piedmont Physiographic Province, is underlain by the intrusive rocks of the Inner Piedmont,
Chauga Belt, Smith River Allochthon, and Sauratown Mountain Anticlinorium, and is within a
migmatitic granitic gneiss formation. A description of the underlying Rock Unit OCgm is foliated
to massive, granitic to quartz dioritic, biotite gneiss and amphibolite common.
According to the United States Department of Agriculture, Natural Resources Conservation
Service, Web Soil Survey, soils at the subject property consist of Urban Land (Ur). Parent
materials were classified as impervious layers over human-transported material.

During the advancement of the soil boring, subsurface soils were primarily classified as a reddish-
brown clay from grade to approximately 10-feet below grade and a reddish-brown clay with some
sand and silt from 10 to 40- feet below grade, with moist soil samples observed from a depth of
approximately 15 to 25-feet below grade, and wet soil samples observed from a depth of
approximately 25 to 40-feet below grade.

According to a review of applicable United States Geologic Survey topographic mapping for the
subject site and onsite observations, it has been determined that natural surface drainage in the
vicinity of the subject site is generally in a southeasterly direction. While not always the case,
groundwater flow direction typically follows the direction of surface water flow, and is, therefore,
anticipated to flow southeasterly. Man-made improvements may alter natural local drainage

8.0 SAMPLING RESULTS
8.1 Phase I Investigation
On September 11, 2023, under the direction of a CES environmental scientist, one soil boring
was installed on the northern portion of the site, in the presumed area of the former UST, to a
depth of approximately 40-feet below grade, after DTW was estimated at between 23 to 25-feet
below grade, to facilitate the completion of one 2-inch diameter permanent groundwater well (MW-
1) for groundwater collection purposes. Soil boring/monitoring well MW-1 was installed by a sub-
contracted driller, Carolina Soil Investigations, LLC of Olin, North Carolina, via augering
techniques, utilizing a track-mounted Geoprobe drill rig (Model 6712DT). Prior to the completion
of MW-1, Monitoring Well Construction Permit Number WM0100555 was obtained from the Water
Quality Regional Operations Section of the NCDEQ Division of Water Resources.

A photographic log depicting the site and soil boring location is included in Appendix A. The Site
Plan, as shown on Figure 2, depicts the location of MW-1. A monitoring well construction log,
soil boring log and GW-1 Well Construction Record for the soil boring/monitoring well are included
as Table B-7 and Appendix D, respectively. The NCDEQ Monitoring Well Construction Permit
is included in Appendix D.

During the advancement of the soil boring, the CES Environmental Scientist field screened
encountered soils with a MiniRAE 2000 Photoionization Detector (PID) for the presence of volatile
organic compounds (VOCs), reported in ppm per volume (ppmv), to facilitate the selection of one
soil sample for subsequent laboratory analysis. PID measurements ranged from 1.5 ppmv,
collected from a soil sample at approximately 15-feet below grade, to 33.2 ppmv, collected from
a soil sample at a depth of approximately 30-feet below grade when groundwater was
encountered.

Based on PID measurements and the approximate depth of encountered groundwater (between
23 to 25-feet below grade), the soil sample at a depth of approximately 18-feet below grade was
collected in laboratory provided vials and glassware, stored on ice, and hand delivered under
COC procedures on September 12, 2023, to Waypoint for laboratory analysis of the following:

 VOCs by 8260 + MTBE/IPE
 sVOCS by 8270 BNA
 MassDEP VPH and EPH
 Metals: Pb + Cr

Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent
concentrations above the Soil-to-Water MSCC, Residential Soil Cleanup Levels, and the
Industrial/Commercial MSCC:

 MW-1: chromium (50.9 mg/kg).

All other concentrations of petroleum-related constituents in soil were reported below Soil-to-
Water MSCC, Residential Soil Cleanup Levels, and the Industrial/Commercial MSCC from MW-
1.

The soil exceedance from MW-1 of the Soil-to-Water MSCC, Residential Soil Cleanup Levels,
and the Industrial/Commercial MSCC for chromium may be related to the elevated concentrations
of native soil. The North Carolina statewide average chromium background level in soil is 32.42

CES Project No. 8195.0823E

mg/kg according to a published document by Cohan & Yang, 2019. The maximum detected
chromium concentration was 50.9 mg/kg during the Phase I LSA.

Figure 3 depicts a Soil Concentration and Estimated Extent of Contamination Map. Table B-3
summarizes soil laboratory analytical results. Soil laboratory analytical reports are included in
Appendix C.

Upon completion of the soil boring to a depth of approximately 40-feet below grade, and
subsequent conversion to a 2-inch diameter monitoring well, DTW measurements were recorded
using a water level meter capable of detecting LNAPL or Free Product to an accuracy of 0.01
feet. LNAPL or Free Product was not detected in groundwater monitoring well MW-1. A DTW
measurement from MW-1 was recorded at approximately 22.59-feet below grade.

After collecting DTW measurements and calculating the volume of water to be removed from MW-
1, a dedicated 1.5-inch disposable bailer was used to develop the well by surging methods, and
then approximately three to five well volumes were purged from the monitoring well. Groundwater
samples were then collected in laboratory provided vials and glassware via the dedicated 1.5-
inch disposable bailer, stored on ice, and hand delivered under COC procedures on September
12, 2023, to Waypoint for laboratory analysis of the following:

 VOCs by SM 6200B extension + 5 oxygenates and 504.1 (EDB)
 Base/Neutrals and Acids by 625 BNA
 MassDEP VPH and EPH
 Metals: PB + Cr

Groundwater laboratory analytical results from MW-1 reported the following petroleum-related
constituent concentrations above the 2L Standard:

 MW-1: chromium (278 ug/l) and lead (22 ug/l).

All other concentrations of petroleum-related constituents in groundwater were reported below 2L
Standards and 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 B. Groundwater analytical reports are included in Appendix C.

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 UST system (removed in December, 1996), 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 on the northern portion of the site, in the presumed area of the former UST, reported
concentrations of petroleum-related constituents (chromium only) above applicable soil
standards, and subsequent groundwater samples collected from MW-1 reported concentrations
of petroleum-related constituents (chromium and lead only) above 2L Standards, but below the
GCL.

The findings of the receptor survey indicated that no known or reported water supply wells have
been identified in the general vicinity of the site.

Recommendations:

Based upon laboratory analysis of soil and groundwater samples collected from MW-1 on
September 11, 2023, reporting petroleum-related constituents above applicable soil and
groundwater standards, including groundwater concentrations reported above the 2L Standard
but below the GCL, without the foreseeable risk of impacting nearby receptors, and without the
presence of any known or reported water wells in the general vicinity of the site, it is of the opinion
of CES that the Site Risk/Ranking is Low, and a Notice of Residual Petroleum (NRP) can be
placed on the property.

However, during any potential and/or future site redevelopment activities, property transactions,
and/or site improvements, it is the recommendation of CES that additional soil, groundwater and
vapor assessment, monitoring and remediation activities be conducted at the site, as the data
obtained and reported herein is representative of conditions only at the referenced boring and
monitoring well location (MW-1), and is not necessarily indicative of conditions elsewhere on the
subject property.

ENVIRONMENTAL MANAGEMENT AND HEALTH AND SAFETY PLAN (EMP)

NCDEQ Project AS-1566_17199
Caldwell County Sherriff’s Office
214 Mulberry Street
Lenoir, Caldwell County, North Carolina

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 AS-1566_17199, 214 Mulberry Street, Lenoir, Caldwell County,
North Carolina, under CES Project Number: 8195.0823E. For the purpose of this plan, the
term “project” references “NCDEQ AS-1566_17199”. 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, drilling 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.

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

2

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 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
be given copies and will be required to follow this EMP.

3

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 monitoring of potentially contaminated soil and groundwater with
petroleum related constituents, and may also include geophysical investigations or utility
clearance, and the installation of soil borings with conversion to permanent monitoring wells
via mechanical drilling techniques, 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, 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
excavations, and/or earthmoving equipment. An evaluation of the potential hazards
associated with site activities has been completed by reviewing the general construction

6

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
be encountered by CES employees while in the field, the hazards and exposures of these
chemicals or hazardous materials will be re-evaluated.

7

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
instrument will be calibrated with methane and H2S according to the manufacturer’s
instructions.

8

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
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.

9

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
made by the SSO

10

· 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)
· Hearing protection (as applicable)
· Steel-toed safety shoes
· Goggles or safety glasses will be worn at all times in the work area

11

· 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)

5.3.2 Level D Protection
Level D protection includes chemical resistant gloves and will be used for site work whenever
contact with contaminated equipment or materials is possible. The following clothing will be
required for Level D:

· Disposable, chemical-resistant outer boots
· Coveralls (work uniform)
· Hard hat
· Eye protection (safety glasses, goggles, or face-shield)*
· Safety shoes
· Nitrile gloves*
* Optional, as determined by SSO

12

Dust masks shall be used to reduce employee exposure to fugitive dust, an optional Level D
device. The absence of dusty conditions at the site will be justification for the SSO to permit
personnel to remove their masks.

5.3.3 Level C Protection
Level C will be used for site work when the inhalation and dermal contact hazard is elevated.
When conditions for Level C protection are appropriate, the following equipment will be
required:
· Tyvek coveralls/chemical-resistant protective coverall
· Gloves (inner latex gloves and outer nitrile gloves)
· Hard hat
· Safety shoes
· Full-face or half-face air purifying respirator with organic vapor
cartridge (or other proper type cartridge for the intended use,
as determined by the SSO)
· Chemical-resistant outer boots
· Tape gloves and boots to coveralls to prevent leakage
· Hearing protection (as determined by SSO)

5.3.4 Level B Protection

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

· No food or beverages will be present or consumed in the
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

respirators). Wear other protective gear as specified in the
Health and Safety Plan

16

· A closed cab or cage will be required for equipment used at the
site

· Pay attention at all times

· Maintain visual contact at all times

· 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.

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

22

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

23

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.

24

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

25

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

26

- 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.

27

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

12.4 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
or Matt Sumner or Chuck Heleine and the Local Fire / Emergency Management agency (Caldwell

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
Suitable extinguishing media
For small fires, Class B fire extinguishing media such as CO2, dry chemical, foam (AFFF/ATC) or water spray can be used. For
large fires, water spray, fog or foam (AFFF/ATC) can be used. Firefighting should be attempted only by those who are adequately
trained and equipped with proper protective equipment.
Unsuitable extinguishing media
Do not use straight water streams to avoid spreading fire.
SDS ID NO.: 0156MAR019 Product name: Marathon Petroleum Benzene Page 3 of 10
Specific hazards arising from the chemical
This product has been determined to be a highly flammable liquid per the OSHA Hazard Communication Standard and should be
handled accordingly. Vapors may travel along the ground or be moved by ventilation and ignited by many sources such as pilot
_____________________________________________________________________________________________
0156MAR019 Marathon Petroleum Benzene Revision Date 05/14/2015
lights, sparks, electric motors, static discharge, or other ignition sources at locations distant from material handling. Flashback can
occur along vapor trail. For additional fire related information, see NFPA 30 or the Emergency Response Guidebook 130.
Hazardous combustion products
Smoke, carbon monoxide, and other products of incomplete combustion.
Explosion data
Sensitivity to Mechanical Impact No.
Sensitivity to Static Discharge Yes.
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

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
