2.0 EXECUTIVE SUMMARY

This Soil Monitoring Report summarizes petroleum hydrocarbon impacts in soil from an apparent
release of petroleum-related constituents from the historical operation of an underground storage
tank (UST or tank) system, located at 1926 Dallas Cherryville Highway, Dallas, North Carolina
(hereafter identified as the site, subject site, subject property, or property), which has been identified
as the O’Shields Well (aka Long Brothers Roofing/Waterproofing). The site location, including
topographic features, is depicted on Figure 1. CES Group Engineers, LLP (CES) has been
authorized to perform monitoring activities by the North Carolina Department of Environmental
Quality (NCDEQ), represented by Scott Ryals, PE, Environmental Engineer.

On July 12, 2023, under the direction of CES, two attempts to install a groundwater monitoring well
in the area of the former UST system were unsuccessful, due to subsurface refusal encountered
twice at depths of approximately 17 and 18-feet below grade, respectively. As a result, and after
email communications with NCDEQ-Mr. Scott Ryals, PE, Environmental Engineer, on July 12,
2023, a total of three soil samples were collected for laboratory analysis during the installation of
two soil borings (SB-1 and SB-2), with one shallow soil sample collected from soils exhibiting
elevated photoionization detector (PID) readings in SB-1, at a depth of approximately 5-feet below
grade, and with two soil samples collected from soils located immediately above encountered
refusal in SB-1 and SB-2, at depths of approximately 17 and 18-feet below grade, respectively, in
order to evaluate the potential for groundwater to be impacted from the migration of mobile
contaminants through fractures within the rock interface.

Upon collection, soil samples from SB-1 and SB-2 were placed in laboratory provided vials and
glassware, stored on ice, and hand delivered under chain-of-custody (COC) procedures on July 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 VPH and EPH by
MassDEP methodologies.

Soil laboratory analytical results from SB-1 and SB-2 reported the following petroleum-related
constituent concentrations above the Soil to Water Maximum Soil Contaminant Concentration
(MSCC), Residential Soil Clean Up Levels and/or Industrial/Commercial MSCC:

 SB-1 (5’): * chromium (11.7 mg/kg), 4-isopropyl toluene (0.228 mg/kg),
** naphthalene (7.77 mg/kg), 1-methynaphthalene (4.33 mg/kg), 2-
methynaphthalene (7.63 mg/kg) and C9-C10 aromatics 250 mg/kg).

 SB-1 (17’): * chromium (25.6 mg/kg).

 SB-2 (18’): * chromium (10.9 mg/kg).

*Concentration reported above Industrial/Commercial MSCC
**Concentration reported above Residential Soil Clean Up Levels

All other concentrations of petroleum-related constituents were reported below Soil to Water MSCC,
Residential Soil Cleanup Levels and Industrial/Commercial MSCC from SB-1 and SB-2.

Based upon encountered refusal, the subsurface investigation portion of this assessment phase
consisted of installing two soil borings (SB-1 and SB-2) within the area of the UST system, without
the monitoring and assessment of groundwater.

CES Project No. 8078.0123E Page 4
August 18, 2023

According to information retrieved from the NCDEQ UST Incidents Map, the site was initially
assigned a High-risk classification by NCDEQ in 1978, due to the presence of organic compounds
similar to gasoline being reported from a nearby water supply well. However, upon abandonment of
potentially impacted and nearby water supply well(s), the site was reassigned a Low-risk
classification in 1988.

Since the reported presence of organic compounds similar to gasoline from a nearby water supply
well in 1978, no known receptors have been impacted by the reported petroleum release, nor are
any receptors known to be at an imminent risk of being impacted based on a limited review of
current subsurface conditions, including soil contaminant levels and the location of contaminants.

Based on field observations during the advancement of soil borings SB-1 and SB-2 on July 12,
2023, reporting the absence of saturated contaminated soils through visual observations from soils
located immediately above the rock interface, and with confirmatory laboratory analytical results
reporting concentrations below the Soil to Water MSCC, Residential Soil Clean Up Levels and/or
Industrial/Commercial MSCC from soil samples collected immediately above the rock interface, with
the exception of chromium, and with the knowledge that the onsite water supply well (1926 Dallas
Cherryville Highway) and a downgradient water supply well (1931 Dallas Cherryville Highway) were
previously abandoned in the late 1970’s, and with the historical and future planned use of the
subject property as a commercial business, it is the opinion of CES that the Site Risk/Ranking is
considered to be Low, and a Notice of Residual Petroleum (NRP) can be placed on the property
without the collection of groundwater samples. This opinion is further based on the reasonable
expectation that since saturated contaminated soils were not encountered immediately above rock
refusal, the migration of mobile contaminants through fractures within the rock interface to the
groundwater table is unlikely.

3.0 SCOPE OF SERVICES

The scope of services for this report were authorized by NCDEQ Task Authorization (TA) #02,
approved on April 20, 2023, under CES Contract Number N042023, dated February 24, 2023. In
accordance with the approved TA, the approved scope of services included the following:

 Install up to one groundwater monitoring well in the area of the former UST system to an
approximate depth of 35-feet below grade;

 Monitor and collect one soil sample during the installation of the groundwater monitoring
well for laboratory analysis of 8260, including MTBE and IPE, 8270 BNA, MassDEP VPH
and EPH, and Metals (Lead and Chromium);

 Monitor and collect a groundwater sample from the newly installed monitoring well for
laboratory analysis of 6200B, including MTBE, IPE and EDB, EPA 625 BNA , 504.1 EDB,
MassDEP VPH and EPH, and Metals (Lead and Chromium); and

 Prepare and submit one groundwater monitoring report summarizing the field and laboratory
analytical findings.

However, after two attempts to install a groundwater monitoring well in the area of the former UST
system were unsuccessful, due to subsurface refusal encountered twice at depths of approximately
17 and 18-feet below grade, respectively, the scope of work for this TA was modified via
communications with NCDEQ-Mr. Scott Ryals, PE, Environmental Engineer, on July 12, 2023, to
install two soil borings (SB-1 and SB-2) within the area of the UST system, with subsequent
collection of soil samples for laboratory analysis, without the monitoring and assessment of
groundwater.

4.3 Non-UST Information
Not Applicable. No ASTs or other above ground vessels or substantial petroleum storage
containers are known to exist at the site, nor could be visually ascertained during site visits
associated with this Soil Monitoring Report.

4.4 Release Description
According to a review of a NCDEQ Pollution Incident / UST Leak Reporting Form, dated June 28,
1989, in July of 1978, Mr. Paul Shields, owner of the property (believed to be 1931 Dallas
Cherryville Highway) located across the street from Long Bros Roofing/Waterproofing (1926 Dallas
Cherryville Highway), reported that water from his water supply well had a petroleum like odor.
Subsequent water samples collected from Mr. Shields’ water supply well on August 1, 1978, by
representatives of the North Carolina Department of Environmental Management (DEM), reported
the presence of organic compounds similar to gasoline. It was further reported that a private lawsuit
was initiated by Mr. Shields against Long Bros Roofing/Waterproofing in 1978 as a result of the
reported contamination, with the outcome of that lawsuit unknown. Based on the reported
presence of contamination in Mr. Shields water supply well, the water supply wells located at 1926
and 1931 Dallas Cherryville Highway were reportedly abandoned and a municipal water supply line
was installed to service properties located along Dallas Cherryville Highway.

According to a review of NCDEQ File Memorandums (1979 through 2018), Long Roofing
Bros/Waterproofing reportedly purchased the property at 1926 Dallas Cherryville Highway in
November 1971, and continued to use the existing USTs (reported to contain gasoline and diesel),
which were reportedly installed by another party in 1967 or 1968. Except for site sketches
indicating that two USTs were designated as being “buried” along the southern portion of 1926
Dallas Cherryville Highway, no further information relative to the 1967 or 1968 USTs was readily
accessible.

According to information retrieved from the NCDEQ UST Incidents Map, the site was initially
assigned a High-risk classification by NCDEQ in 1978, due to the presence of organic compounds

CES Project No. 8078.0123E Page 8
August 18, 2023
similar to gasoline being reported from a nearby water supply well. However, upon abandonment of
the potentially impacted and nearby water supply well(s), the site was reassigned a Low-risk
classification in 1988.

Historical reports, including the NCDEQ Pollution Incident / UST Leak Reporting Form, dated June
28, 1989, and NCDEQ File Memorandums from 1979 through 2018, are included in Appendix A.

Since the sampling and subsequent abandonment of water supply well(s) in 1978, no further
investigative measures are known to have occurred for Incident Number 5102.

4.5 Site Characteristics
According to Gaston County GIS Maps, the subject property is listed with a zoning code of General
Industry (I-2), with Gaston County Parcel Identification Number 3547080271, occupying a total
approximate area of 1.23-acres. The subject site contains one structure located on the central
portion of the site, an approximate 18,140-square foot building currently operating as a lawn
mowing parts and landscape supplies facility, and was reportedly constructed in the year 1969. The
remainder of the subject site contains hard-packed gravel, asphalt-paved and concrete entrance
ways and parking areas, and landscaped areas. Based on onsite observations and a review of
historical documents, natural surface drainage at the subject property generally flows in a southerly
direction. While not always the case, groundwater flow direction typically follows the direction of
surface water flow, and is, therefore, anticipated to flow southerly. The subject site is served by
electrical and telecommunication utilities, as well as public water distribution and sanitary sewer
services provided by the Town of Dallas. No water supply wells or septic systems were observed
onsite. The subject site is situated in an area of commercial, residential, agricultural, and
institutional land use. The site location in relation to area land use is illustrated in Figures 1 and 4.

4.6 Affected Property Owners and Occupants
Land use in the vicinity of the subject property can be characterized as commercial, residential,
agricultural, and institutional land uses. Based on petroleum-related constituents in soil primarily
reported below laboratory detection limits and below applicable state soil standards, except for
chromium encountered in soil samples collected from immediately above the rock interface, at
depths of approximately 17 and 18-feet below grade, and VOCs reported from a shallow soil
sample collected from SB-1, at a depth of approximately 5-feet below grade, and with the
reasonable expectation that groundwater has not been impacted at the site based on the reported
absence of petroleum-related constituents from soil samples collected immediately above the rock
interface, nearby and surrounding property owners and occupants are not expected to be currently
impacted by the apparent release from Incident Number 5102. Additionally, although water supply
wells are known to exist in the general vicinity of the site, as reported in the Receptor Survey
Report, dated April 7, 2023, since the initial report of contamination in water supply wells from the
late 1970’s, no additional water quality issues relative to petroleum-related constituents are known
to have been reported by nearby property owners.

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 Beacon Hall Youth Center located approximately

CES Project No. 8078.0123E Page 9
August 18, 2023
600-feet to the east, the Christian Community Academy located approximately 1,100-feet to the
west-northwest, and Maranatha Baptist Church located approximately 1,500-feet to the east-
southeast of the site. Aerial imagery depicting land use in the general vicinity of the site is included
on Figure 4.
4.7 Receptor Information
A Receptor Survey was previously completed at the site by CES in February and March, 2023, with
the information submitted to NCDEQ in a Receptor Survey Report, dated April 7, 2023, which is
summarized below:

Windshield and Walking Survey:

On March 30, 2023, a representative of CES conducted a windshield and walking survey of the
subject property, and accessible properties withing a 500-feet radius of the site. Visual information
obtained from the windshield and walking survey has been summarized as follows:

 Water supply well(s) were not visually identified on the site, nor on properties located along
Dallas Cherryville Highway and Wallace Lane;
 A former pump island was visually identified on the southern portion of the site;
 Municipal water lines and fire hydrants were observed along Dallas Cherryville Highway,
and Wallace Lane; and
 Numerous water supply well structures were observed on residential properties located on
roadways further to the south of the site (Pinckney Road, Garden Terrace and Hoke Drive).

Water Supply Wells:
A water supply well survey was conducted by interviewing the occupant of the subject property,
conducting the windshield survey on March 30, 2023, contacting the Town of Dallas Public Works
Department, and sending out Request for Water Supply Well Information forms to property owners
located within a 1,500-feet radius of the subject property.

According to information obtained from nearby and surrounding property owners, and the Town of
Dallas, water supply wells are known to exist within a 1,500-feet radius of the site.

On February 28, 2023, CES sent out Request for Water Supply Well Information forms to a total of
107 properties within a 1,500-feet radius of the subject property. A total of 12 Water Supply Well
Information forms were returned to CES, or information was otherwise communicated to CES,
which reported the presence of 6 water supply wells within a 1,500-feet radius of the site.

Per conversations with Mr. Bill Trudnak, Public Works Director for the Town of Dallas, municipal
water lines exist along Dallas Cherryville Highway and Wallace Lane, however, do not extend down
Pinckney Road, Garden Terrace, or Hoke Drive. Based on the windshield and walking survey, and
from information from Mr. Trudnak, water supply wells are present further to the south of the site,
beyond Dallas Cherryville Highway.

Public Water Supplies:
According to the 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. The nearest public water
supply well, associated with the Christian Fellowship Church, located at 2352 Dallas Cherryville
Highway, is approximately 2,700-feet to the west-northwest of the site.

CES Project No. 8078.0123E Page 10
August 18, 2023
Municipal water distribution systems provided by the Town of Dallas are available to serve the
subject property and surrounding properties.

Surface Water:
The nearest surface water body to the site, Little Long Creek, a Class C surface water body
according to the NC One Map - Surface Water Classifications, is located approximately 1,650-feet
to the north of the reported location of the buried USTs. Class C surface waters are protected for
uses such as aquatic life propagation, survival, and maintenance of biological integrity (including
fishing and fish), wildlife, secondary contact recreation, and agriculture. Secondary contact
recreation means wading, boating, other uses not involving human body contact with water, and
activities involving human body contact with water, where such activities take place on an
infrequent, unorganized, or incidental basis.

According to the NC One Map – Surface Water Intakes Map, no surface water intakes are located
within a 1,500-feet radius of the subject site.

Wellhead Protection Areas:
According to the NC SWAP website, the subject property is not located within a wellhead protection
area. One approved wellhead protection plan, associated with Belmont Abbey College, is listed in
Gaston County. Belmont Abby College is located approximately 13-miles to the east-southeast of
the site.

Deep Aquifers in the Coastal Plain Physiographic Region:
Not Applicable to the subject site as the site lies within the Piedmont Physiographic Region.

Subsurface Structures:
Underground utilities have been identified at and adjacent to the subject site, and potential soil and
groundwater contamination may be in contact with these underground utilities. According to
historical documents associated with the former water supply wells located at 1926 and 1931 Dallas
Cherryville Highway, groundwater was measured at approximately 30-feet below ground surface at
the site in the late 1970’s. Because the underground utilities are expected to be at a shallower
depth than 30-feet, the utility lines would not be considered receptors or conduits for groundwater
contaminant migration. However, updated groundwater monitoring and assessment data would
need to be collected at the site to determine depth to groundwater, and the potential for utilities to
be considered receptors or conduits for groundwater contamination migration. No subsurface
structures have been identified at the site.

Figure 4 depicts a 1,500-feet Potential Receptor and Land Use Map.

Table B-5 summarizes public and private water supply well and other receptor information.

4.8 Remedial Plan Implementation
To date, it is the understanding of CES that a remedial plan has not been submitted and/or
implemented for the subject site.
4.9 Remediation Progress
Not Applicable.

CES Project No. 8078.0123E Page 11
August 18, 2023
5.0 CURRENT SITE ASSESSMENT INFORMATION

Prior to the commencement of field monitoring and sampling activities, CES prepared and reviewed
a site-specific Job Hazards Analysis (JHA) and Emergency Management and Health & Safety Plan
(HASP) acknowledging that potential hazards exist onsite, which were properly recognized and
evaluated by onsite personnel. A copy of the site-specific JHA and HASP are included in Appendix
C.

5.1 Water Level and Free Product Thickness Measurements
Not Applicable. No water level and free product measurements were collected during this
assessment phase due to encountered subsurface refusal at approximately 17 and 18-feet below
grade without encountering subsurface groundwater.

5.2 Groundwater Monitoring Event
Not Applicable. No groundwater monitoring events were conducted during this assessment phase
due to encountered subsurface refusal at approximately 17 and 18-feet below grade without
encountering subsurface groundwater.

5.3 Surface Water Monitoring Event
Not Applicable. No surface water monitoring events were conducted during this assessment phase.

5.4 Soil Monitoring Events
On July 12, 2023, under the direction of CES, two attempts to install a groundwater monitoring well
in the area of the former UST system were unsuccessful, due to subsurface refusal encountered
twice at depths of approximately 17 and 18-feet below grade, respectively. As a result, and after
email communications with NCDEQ-Mr. Scott Ryals, PE, Environmental Engineer, on July 12,
2023, a total of three soil samples were collected for laboratory analysis during the installation of
two soil borings (SB-1 and SB-2), with one shallow soil sample collected from soils exhibiting
elevated PID readings in SB-1, at a depth of approximately 5-feet below grade, and with two soil
samples collected from soils located immediately above encountered refusal in SB-1 and SB-2, at
depths of approximately 17 and 18-feet below grade, respectively, in order to evaluate the potential
for groundwater to be impacted from the migration of mobile contaminants through fractures within
the rock interface.

Upon collection, soil samples from SB-1 and SB-2 were placed in laboratory provided vials and
glassware, stored on ice, and hand delivered under COC procedures on July 12, 2023 to Waypoint
for laboratory analysis of VOCs by 8260, sVOCs by 8270, Metals (Pb & Cr) and VPH and EPH by
MassDEP methodologies.

Prior to arriving onsite on July 12, 2023, Monitoring Well Construction Permit Number WM0301298
was obtained from the Water Quality Regional Operations Section of the NCDEQ Division of Water
Resources for the planned installation of one proposed groundwater monitoring well.

Figure 2, Site Plan, depicts the location of soil borings SB-1 and SB-2. Soil boring logs for SB-1
and SB-2 are included in Appendix E. The Monitoring Well Construction Permit is included in
Appendix E.

5.5 Summary of Soil, Groundwater, Surface Water and Free Product Assessment
Information
Soil laboratory analytical results from SB-1 and SB-2 reported the following petroleum-related
constituent concentrations above the Soil to Water MSCC, Residential Soil Clean Up Levels and/or
Industrial/Commercial MSCC:

 SB-1 (5’): * chromium (11.7 mg/kg), 4-isopropyl toluene (0.228 mg/kg),
** naphthalene (7.77 mg/kg), 1-methynaphthalene (4.33 mg/kg), 2-
methynaphthalene (7.63 mg/kg) and C9-C10 aromatics 250 mg/kg).

 SB-1 (17’): * chromium (25.6 mg/kg).

 SB-2 (18’): * chromium (10.9 mg/kg).

*Concentration reported above Industrial/Commercial MSCC
**Concentration reported above Residential Soil Clean Up Levels

All other concentrations of petroleum-related constituents were reported below Soil to Water MSCC,
Residential Soil Cleanup Levels and Industrial/Commercial MSCC from SB-1 and SB-2.

Figure 2 depicts the location of soil borings SB-1 and SB-2. A soil contamination plan for the July
12, 2023 soil monitoring event is included as Figure 3. A summary of soil analytical results is
included on Table B-3. Copies of soil laboratory analytical reports are included as Appendix D.
5.6 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 Kings Mountain Belt,
and is within a foliated to massive granitic rock formation. A description of the underlying Rock Unit
PPmg is megacrystic to equigranular, and high schoals granite.
According to the US Department of Agriculture, Natural Resources Conservation Service, Web Soil
Survey, soils at the subject property consist of Cecil-Urban Land Complex, which generally have a 0
to 2 percent slope, and are classified as well drained sandy clay loam (0 to 6-inches), clay (6 to 40-
inches), clay loam (40 to 55-inches) and sandy loam (55 to 80-inches). Parent materials were
classified as impervious layers over human transported material.

As referenced in a review of available, and historical documents, specifically from North Carolina
Division of Environmental Management Memorandums from the late 1970’s, groundwater was
estimated to flow in a southerly direction across the site.

5.7 Evaluation of Soil, Groundwater, Surface Water and Free Product Thickness
Information
Based on VOC and chromium concentrations reported above applicable state soil standards from
SB-1 and SB-2, the extent of the soil contaminant plume is estimated to be limited to the areas near
the former dispenser island and USTs, as depicted on Figure 3.

No free product, groundwater or surface water monitoring events were conducted during this
assessment phase.

The data obtained and reported herein is representative of conditions only at the referenced soil
boring locations, and is not necessarily indicative of conditions elsewhere on the subject site.

9.0 CONCLUSIONS AND RECOMMENDATIONS

9.1 Conclusions
The findings of the July 12, 2023 field related activities are as follows:

 Due to refusal encountered twice at approximately 17 and 18-feet below grade, attempts to
install one groundwater monitoring well in the area of the former UST system were
unsuccessful;
 Two soil borings, SB-1 and SB-2, were installed in the area of the former UST system, with
subsequent soil samples collection for laboratory analysis; and
 Petroleum constituents were reported above applicable state soil standards from soil
samples collected from SB-1 and SB-2.
9.2 Recommendations
Based on field observations during the advancement of soil borings SB-1 and SB-2 on July 12,
2023, reporting the absence of saturated contaminated soils through visual observations from soils
located immediately above the rock interface, and with confirmatory laboratory analytical results
reporting concentrations below the Soil to Water MSCC, Residential Soil Clean Up Levels and/or
Industrial/Commercial MSCC from soil samples collected from immediately above the rock
interface, with the exception of chromium, and with the knowledge that the onsite water supply well
(1926 Dallas Cherryville Highway) and a downgradient water supply well (1931 Dallas Cherryville
Highway) were previously abandoned in the late 1970’s, and with the historical and future planned
use of the subject property as a commercial business, it is the opinion of CES that the Site
Risk/Ranking is considered to be Low, and a Notice of Residual Petroleum (NRP) can be placed on
the property without the collection of groundwater samples. This opinion is further based on the
reasonable expectation that since saturated contaminated soils were not encountered immediately
above rock refusal, the migration of mobile contaminants through fractures within the rock interface
to the groundwater table is unlikely.

ENVIRONMENTAL MANAGEMENT AND HEALTH AND SAFETY PLAN (EMP)

NCDEQ Project MO-2875_5102
O’Shields Well
1926 Dallas Cherryville Highway
Dallas, Gaston 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 MO-2875_5102, 1926 Dallas Cherryville Highway, Dallas,
Gaston County, North Carolina, under CES Project Number: 8078.0123E. For the purpose
of this plan, the term “project” references “NCDEQ MO-2875_5102”. 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

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
- Changes in coordination
- Changes in demeanor

pupillary response
- Changes in speech pattern

Field personnel will be cautioned to inform the SSO of non-
visible effects of exposure such as the following:

- Headaches
- Dizziness
- Nausea
- Blurred vision
- Cramps
- Irritation of eyes, skin, or respiratory tract
·
7.2 HEAVY EQUIPMENT OPERATION
Extra attention should be paid to the following information regarding work around heavy
equipment (cranes, excavators, front end/backhoe loaders, drilling rigs, etc.).

· Use common sense

· Follow OSHA requirements found in 29 CFR 1910 and 29 CFR
1926

· Wear hard hats, hearing protection, and safety glasses at all

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.
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
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

_____________________________________________________________________________________________
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
appropriate.
Environmental precautions:Avoid release to the environment. Avoid subsoil penetration.
Methods and materials for
containment:

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.

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.
