2.0 EXECUTIVE SUMMARY
This Groundwater Monitoring Report (GW Report) summarizes petroleum hydrocarbon impacts in
groundwater from an apparent release of petroleum-related constituents from a retail petroleum
underground storage tank (UST or tank) system, located at the former Snyder’s Phillips 66, 823
West Center Street, Lexington, Davidson County, North Carolina (hereafter identified as the site,
subject site, subject property or property). CES Group Engineers, LLP (CES) has been authorized
to perform groundwater monitoring activities by the North Carolina Department of Environmental
Quality (NCDEQ), represented by Scott Ryals, PE, Environmental Engineer.
During this monitoring period, one permanent groundwater monitoring well (MW-6) was installed
along the southern property boundary, to a depth of approximately 35-feet below grade on January
19, 2023, in an attempt to delineate the horizontal extent of the contaminate plume towards the
south, with a soil sample collected from MW-6, and subsequent groundwater samples collected
from previously installed MW-5, and MW-6 on January 19, 2023 for analysis of petroleum
hydrocarbon constituents.
Petroleum-related constituent concentrations in soil were reported ABOVE the Soil to Water
Maximum Contaminant Concentration (MSCC) from the following monitoring well:
MW-6: benzene (0.037 mg/kg) and MTBE (0.598 mg/kg).
All other concentrations of petroleum-related constituents were reported below Soil to Water MSCC,
and Residential Soil Cleanup Levels and Industrial/Commercial MSCC from MW-6.
Petroleum hydrocarbon constituents in groundwater were reported ABOVE the 2L Standard from
the following monitoring wells:
MW-5: benzene (GCL), DIPE, chloroform, ethylbenzene, 2-hexanone, isopropyl
benzene, MTBE (GCL), 4-methyl 2-pentanone, naphthalene, n-propyl
benzene, styrene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene,
total xylenes, 1-methylnaphthalene, 2-methylnaphthalene, C11-C22
aromatics, C5-C8 aliphatic, C9-C12 aliphatic and C9-C10 aromatics.
MW-6: benzene, DIPE, MTBE, naphthalene, total xylenes, 1-methylnaphthalene,
C11-C22 aromatics, C5-C8 aliphatic, C9-C12 aliphatic and C9-C10
aromatics.
Petroleum hydrocarbon constituents in groundwater were reported ABOVE the GCL Standard from
the following monitoring wells:
MW-5: benzene and MTBE.
All other concentrations of petroleum-related constituents were reported below 2L and GCL
standards from MW-5 and MW-6.
It should be noted that monitoring wells MW-1 and MW-2 were previously installed at the site as
temporary monitoring wells in July of 2022 as part of Limited Site Assessment (LSA) activities, and
three permanent monitoring wells MW-3, MW-4 and MW-5 were installed on October 13, 2022 to
evaluate the extent of the contaminant plume. Previous groundwater analytical results reported
concentrations of benzene above the GCL from a groundwater sample collected from MW-1
CES Project No. 7919.0522E Page 4
February 3, 2023
(temporary well) in July 2022, and concentrations of benzene and MTBE above the GCL from a
groundwater sample collected from MW-5 (permanent well) in October 2022.
Free product has not been detected in any of the onsite groundwater monitoring wells.
According to information retrieved from the NCDEQ UST Incidents Map, the site was previously
assigned a Low-Risk classification by NCDEQ.
To date, 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
groundwater conditions, including contaminant levels and the location of contaminants, and site
uses.
This report provides data necessary to fulfill a GW Monitoring Report, in accordance with 15A
NCAC 2L.0100, and is formatted in conformance with Appendix A of the Guidelines for Assessment
and Corrective Action for UST Releases, dated March 7, 2022.

4.0 SITE HISTORY AND CHARACTERIZATION
The subject site where groundwater monitoring and sampling was performed, where contaminated
soil was discovered during the performance of upgrade work to an UST system in November 1991
(Incident Number 14039), consists of one parcel, identified as Davidson County Parcel Identification
Number (PIN) 1109200000001, and is situated at the intersection of West Center Street and Shoaf
Street, as shown on Figure 1. The site is located in an urban area of Lexington, Davidson County,
North Carolina, with West Center Street to the north, Shoaf Street to the west, an outlet store (The
Outlet Warehouse) to the east and a law firm (Smith Leonard PLLC) to the south, and is situated in
an area of mixed historical land use, including heavy commercial, residential, industrial and
manufacturing purposes. The site is currently utilized for minor automotive repairs on a periodic
basis. It is understood that three 6,000-gallon, single-wall steel, gasoline USTs remain in the
subsurface, and are located to the west of the onsite building, adjacent to Shoaf Street, and four
fuel dispensers are located to the north of the onsite building, adjacent to West Center Street.
Portions of the property to the north and west of the onsite building are surfaced with concrete. To
the east of the building is a grassy/soil-based surface. To the south of the onsite building is a
grassy area that slopes to the south. Figure 2 depicts pertinent site features.
The subject site was issued Incident Number 14039 in November, 1991, after soil contamination
was encountered from underneath product piping undergoing upgrades. In July of 2022, CES
completed a LSA at the site, which reported the presence of groundwater contamination from a
temporary monitoring well (MW-1) installed in the area of the November, 1991 product piping
upgrades.
Historical data sheets for the November 1991 product piping upgrade activities are included in
Appendix A. Site Photographs are included in Appendix B.

4.2 UST Information
According to the NCDEQ Registered Tanks Database, the retail petroleum UST system (three
6,000-gasoline USTs) lists an installation date of May 13, 1964, with no permanently closed date
listed, with the UST system last owned and operated by Monroe Snyder. According to reviewed
information, it is unknown when the UST system was last in operation. Additionally, during LSA
field activities conducted in July of 2022, a heating oil UST was presumed to exist, adjacent to the
east facing exterior wall of the onsite building, based upon observations of a fill port emanating from
the subsurface, and a vent pipe attached to the exterior wall of the onsite building.

4.4 Release Description
As reported by Enviro-Tank, Inc (Enviro-Tank) during upgrades to the retail petroleum UST system
and subsequent collection of soil samples near the tank system in November, 1991, soil sample 2
collected from underneath the UST systems product piping, at a depth of approximately 12-feet
below grade, reported elevated concentrations of total petroleum hydrocarbons (TPH), identified as
gasoline.
During the completion of the LSA by CES in July of 2022, groundwater samples collected from
temporary monitoring well MW-1, located in the area of the soil sample 2 (collected in 1991 as
CES Project No. 7919.0522E Page 8
February 3, 2023
referenced above), reported petroleum-related constituents above 2L Standards, with a
concentration of benzene (7,890 ug/l) reported above the GCL Standard.
Groundwater sampling activities completed after the installation of three permanent groundwater
monitoring wells MW-3, MW-4 and MW-5 in October, 2022, reported petroleum-related constituents
above 2L Standards in MW-3 and MW-5, with concentrations of benzene (9,700 ug/l) and MTBE
(34,300 ug/l) reported above the GCL Standard in MW-5, which is located to the south, and
downgradient of the existing USTs.
The approximate location of the UST system in relation to the groundwater monitoring wells at the
site is depicted on Figure 2.
4.5 Site Characteristics
The subject property is zoned as City Zoning B in Lexington, according to Davidson County GIS
Real Estate Maps, and includes one parcel, with Davidson County Parcel Identification Number
(PIN) 1109200000001, occupying an area of approximately 0.5-acre. According to Davidson
County GIS Real Estate Maps, the Highest and Best Use of the subject property has been identified
as a Service Station. The adjoining property to the north of the site is West Center Street, with a
large commercial or industrial building (D.H. Griffin Companies) located across West Center Street.
The adjoining property to the east of the site is occupied by a commercial building (The Outlet
Warehouse). The adjoining property to the south of the site is occupied by a commercial building
(Smith Leonard PLLC). The adjoining property to the west is Shoaf Street public right-of-way, with
a commercial building (Leonard Cleaners) located across Shoaf Street.
The subject property currently operates as an unnamed minor automotive repair facility on a
periodic basis. It is understood that future plans for the subject property include the operation as a
full-time gasoline service station, including automotive repairs and the retail sale of gasoline from
the existing UST system. The three 6,000-gallon, single-wall steel, gasoline USTs that remain in
the subsurface are located to the west of the onsite building, adjacent to Shoaf Street, and four fuel
dispensers are located to the north of the onsite building, adjacent to West Center Street. The one-
story, slab on grade, onsite structure contains approximately 4,200-square feet, includes an
attached canopy, three service bays with overhead garage doors, an office area, and also includes
a Barber Shop and Salon operating within the west-southwestern portion of the onsite building, and
was reportedly constructed in the year 1951. No further information relative to the onsite building
was readily available.
The site is situated along the south line of West Center Street, a four (4)-lane, asphalt surfaced,
rural section roadway, and is intersected by Shoaf Street, a two (2)-lane, asphalt surfaced, rural
section roadway. The subject site is served by electrical utilities, with the presumed heating oil UST
and heating oil AST providing a source of heat for the automotive repair facility and the Barber and
Salon, respectively. Public water distribution and sanitary sewer services are available to serve the
site.
The site location in relation to area land use is illustrated in Figures 1 and 2.
4.6 Affected Property Owners and Occupants
The subject site where the contamination was initially discovered in November, 1991, with
CES Project No. 7919.0522E Page 9
February 3, 2023
contamination remaining in-situ, as evident by groundwater analytical results reported from
temporary monitoring well MW-1 sampled during the LSA in July of 2022, from monitoring wells
MW-3 and MW-5 sampled during a groundwater monitoring event on October 14, 2002, and from
monitoring wells MW-5 and MW-6 sampled during this monitoring event in January 2023, have
come to be generally located in the area of the UST system, as well as downgradient of the UST
system towards the south.
The 2L groundwater contaminate plume extends southerly beyond monitoring well MW-6 for an
unknown extent, and potentially extends to the west-southwest. Based on laboratory analytical
results from monitoring well MW-6 in January, 2023, reporting groundwater concentrations below
the GCL Standard, the GCL groundwater contaminate plume currently does not extend to
monitoring well MW-6. Based on collected data, adjoining property owners and occupants to the
south and west-southwest of the site may be affected, due to the reasonable expectation that
groundwater impacts would be present on these properties.
4.7 Receptor Information
Water Supply Wells:
Conducting a water supply well receptor survey was outside the scope of services for this
groundwater monitoring event. However, in accordance with the LSA completed by CES at the site
in July of 2022, one water supply well that is not used for drinking water purposes is located at 200
Shoaf Street, approximately 600 feet to the south of the site. The property owner, Mr. Michael
Smith, confirmed that the property at 200 Shoaf Street is connected to, and served by, the
municipal water distribution system, and the water supply well is not used for drinking water
purposes.
Public Water Supplies:
No public water supplies are known to exist within a 1,500-feet radius of the subject property.
Municipal water distribution systems provided by the City of Lexington are available to serve the
subject property and surrounding properties.
Surface Water:
According to the NC SWAP website, Michael Branch, a Class C surface water body, is located
approximately 750-feet to the west of the source area at its nearest point. 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.
Wellhead Protection Areas:
According to the NC SWAP website, no wellhead protection areas are in Davidson County.
Deep Aquifers in the Coastal Plain Physiographic Region:
Not Applicable to the subject site.
Subsurface Structures:
Underground utilities have been identified at and adjacent to the subject site, and the potential
exists for soil and groundwater contamination to be in contact with these underground utilities.
CES Project No. 7919.0522E Page 10
February 3, 2023
Groundwater has historically been measured at approximately 24 to 27-feet below ground surface
at the site. Because the underground utilities are expected to be at a substantially shallower depth
than 24 to 27-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, except for the
existing USTs.
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. 7919.0522E Page 11
February 3, 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, and 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
During this monitoring period, depth to groundwater measurements were collected from MW-5 and
MW-6.
Depth to groundwater was measured and recorded utilizing 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 any site related monitoring wells, nor has been detected in any
onsite monitoring wells.
After measuring depth to groundwater at each monitoring well, the water level meter was
decontaminated by using a soapy water mixture (alconox and water).
Depth to groundwater ranged from 26.64 feet below top of casing (TOC) in MW-5 to 24.95 feet
below TOC in MW-6, on January 19, 2023. Based on visual observations and historical data,
groundwater flow direction is anticipated to flow in a southerly direction. A summary of depth to
groundwater measurements are included in Appendix C and on Table B-9.
5.2 Groundwater Monitoring Event
After collecting depth to groundwater measurements, and after calculating the volume of water to be
removed from MW-5 and MW-6, a dedicated 1.5-inch disposable bailer was used to develop MW-6
utilizing surging methods, and then approximately three to five well volumes were purged from each
monitoring well on January 19, 2023, utilizing dedicated disposable bailers for each well.
Groundwater samples were then collected on January 19, 2023 in laboratory provided glassware,
placed on ice and submitted under chain of custody (COC) procedures to Waypoint Analytical
(Waypoint), of Charlotte, NC, for analysis of SM 6200B including MTBE, IPE and EDB, 625 BNA,
VPH and EPH.
5.3 Surface Water Monitoring Event
Not Applicable. No surface water monitoring events were conducted during this groundwater
monitoring and sampling event.
5.4 Soil Monitoring Events
On January 19, 2023, one permanent groundwater monitoring well (MW-6) was installed along the
southern property boundary in an attempt to delineate the horizontal extent of the contaminate
plume toward the south. MW-6 was installed approximately 42-feet to the south of MW-5. During
CES Project No. 7919.0522E Page 12
February 3, 2023
the installation of MW-6, encountered soils were field screened in 5-foot increments, from grade to
approximately 35 feet below grade, with a MiniRAE 2000 photoionization detector (PID), calibrated
to detect volatile organic compounds (VOCs) in parts per million per volume (ppmv). PID
measurements from the installation of groundwater monitoring well MW-6 are presented below:
Date Monitoring Well Depth (feet) PID (ppmv)
01/19/2023 MW-6 0 - 5 0.0
5 - 10 0.0
10 - 15 0.0
15 - 20 0.0
20 - 25 0.0
25 - 30 197
During the installation of MW-6 on January 19, 2023, one soil sample was collected immediately
above the water table, at a depth of approximately 25-feet below grade, placed in laboratory
provided vials and glassware, stored on ice, and hand delivered under chain-of-custody (COC)
procedures on January 20, 2023 to Waypoint for laboratory analysis of VOCs by 8260 and VPH
MassDEP methodologies.
Monitoring well construction information for MW-6 is included on Table B-7. Well construction
records, provided by the driller, Carolina Soil Investigations, Inc, and a monitoring well construction
permit, Permit Number WM0401424, issued by the NCDEQ Division of Water Resources, are
included in Appendix E.

CES Project No. 7919.0522E Page 13
February 3, 2023
MW-5: benzene and MTBE.
All other concentrations of petroleum-related constituents were reported below 2L and GCL
standards from MW-5 and MW-6.
Previous groundwater analytical results reported concentrations of benzene above the GCL from a
groundwater sample collected from MW-1 (temporary well) in July 2022, and concentrations of
benzene and MTBE above the GCL from a groundwater sample collected from MW-5 (permanent
well) in October 2022.
A groundwater elevation plan for the January 19, 2023 groundwater monitoring event is included as
Figure 3. A benzene and MTBE isoconcentration plan for the July 14, 2022, October 14, 2022 and
January 19, 2023 groundwater sampling events is included as Figure 4. A summary of soil and
groundwater analytical results are included on Table B-3 and B-4, respectfully. Copies of soil and
groundwater 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
mafic metavolcanic rocks of the Charlotte and Milton Belts. Mafic metavolcanic rocks are
characterized as metamorphosed basaltic to andesitic tuffs and flows, greyish green to black, and
locally includes hypabyssal intrusives and minor felsic metavolcanic rocks.
Based upon groundwater surface elevations, as measured from onsite monitoring wells in July and
October 2022, and in January 2023, as summarized in Table B-9, and from onsite observations
relative to the general gradient at the site, apparent groundwater movement across the site is
presumed to flow in a southerly direction. A groundwater elevation plan for the January 19, 2023
groundwater monitoring event, depicting the groundwater elevations and apparent flow direction to
the south, is presented as Figure 3.
5.7 Evaluation of Soil, Groundwater, Surface Water and Free Product Thickness
Information
Based upon petroleum-related constituents reported above the 2L Standard from monitoring wells
MW-1 (temporary), MW-3, MW-5 and MW-6, and above the GCL Standard in monitoring wells MW-
1 (temporary) and MW-5, which were installed upgradient (MW-1 and MW-3) and downgradient
(MW-5) of the existing UST system, the extent of the contaminant plume is estimated to potentially
extend west-southwesterly towards, and across Shoaf Street, and extends southerly toward and
beyond the adjoining property to the south of the site.
The estimated extent of the 2L and GCL contaminant plumes, as reported by benzene and MTBE
concentrations, is depicted on Figure 4.
Free product was not detected in any of the onsite groundwater monitoring wells.
No surface water monitoring events were conducted during this groundwater monitoring and
sampling event.
The data obtained and reported herein is representative of conditions only at the referenced
monitoring well 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 January 19, 2023 groundwater monitoring and sampling event are as follows:
One groundwater monitoring well (MW-6) was installed to an approximate depth of 35-feet
below grade;
Field screening measurements during the installation of MW-6 ranged from non-detect (Ie,
0.0 ppmv) to 197 ppmv, collected at a depth of approximately 25-feet below grade;
One soil sample was collected during the installation of MW-6, at a depth of approximately
25-feet below grade, and analyzed for 8260 and MassDEP VPH;
Two groundwater monitoring wells (MW-5 and MW-6) were monitored and sampled for SM
6200B including MTBE, IPE and EDB, 625 BNA, VPH and EPH;
LNAPL or Free Product was not detected in MW-5 and MW-6;
Depth to groundwater measurement ranged from 26.64 feet below TOC in MW-5 to 24.95
feet below TOC in MW-6;
Apparent groundwater flow direction is to the south;
Petroleum constituents in soil were reported ABOVE Soil MSCC in MW-6;
Petroleum constituents in groundwater were reported ABOVE the 2L Standard in MW-5 and
MW-6; and
Petroleum constituents (benzene and MTBE) in groundwater were reported ABOVE the
GCL Standard in MW-5.
9.2 Recommendations
Based upon groundwater concentration levels reported above the 2L Standard from monitoring
wells MW-3, MW-5 and MW-6, and above the GCL Standard from monitoring well MW-5 during this
monitoring period, and with the previous 2L and GCL exceedance from temporary monitoring well
MW-1 (July 2022), it is recommended that an additional monitoring well be installed on the adjoining
property to the south of the subject site, in an attempt to delineate the 2L groundwater contaminate
plume, and active remedial alternatives, ie enhanced vapor fluid recovery (AVFR) or equivalent, be
explored to mitigate the GCL groundwater contaminate plume.
Additionally, an evaluation (ie, tank, line and apparatuses testing) of the existing UST system is
recommended to determine if the tanks should be removed from the subsurface, or if the tank
system can be reactivated for the retail sale of petroleum, according to proposed future plans at the
subject property.

ENVIRONMENTAL MANAGEMENT AND HEALTH AND SAFETY PLAN (EMP)
NCDEQ WS-4337/5762_14039/20707 Snyder’s Phillips 66
828 West Center Street, Lexington, Davidson County, NC
1.0 INTRODUCTION
This Environmental Management and Health and Safety Plan (EMP), additionally referred to
as the ‘plan”, has been developed for CES Group Engineers, LLP (CES), for application to
work completed during Project, NCDEQ WS-4337/5762_14039/20707 Snyder’s Phillips 66,
located at 828 West Center Street, Lexington, Davidson County, North Carolina, under CES
Project Number: 7919.0522E. For the purpose of this plan, the term “project” references
“NCDEQ WS-4337/5762_14039/20707 Snyder’s Phillips 66”. 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 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. 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
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
2
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, 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 the geophysical investigation and installation of
soil borings with conversion to temporary monitoring wells, groundwater monitoring and
sampling, and future site assessment, monitoring and/or remediation activities associated
with said borings, 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 a geophysical investigation, and the installation of soil borings with
conversion to temporary monitoring wells via mechanical drilling techniques, groundwater
sampling, and potential future assessment, monitoring and remediation of soil and
groundwater contaminants potentially encountered by said 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. 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
6
associated with site activities has been completed by reviewing the general construction
scope of work for each of the projects, to be performed by others. The following potential
exposure pathways have been identified:
· Dermal contact, inhalation and ingestion of contaminated soils and
groundwater
· Inhalation and ingestion of contaminated vapors and particles
· Ingestion of waste solids (accidental/poor hygiene)
· Dermal contact with waste solids
Given that subsurface investigation activities may occur in close proximity to ongoing or future
construction (ie, excavations) related activities that may disturb surficial and subsurface soils,
pipes, etc and the physical properties of the contaminants that may be present at these
locations, there is a potential respiratory hazard from contaminants such as petroleum related
compounds, and therefore a contact hazard from petroleum related compounds. A
respiratory hazard from dust and contaminated dust particles may also exist during nearby
drilling, excavation and removal activities.
It is recognized that site hazard evaluation is a dynamic and on-going process that changes
on a daily basis during progression of the work. However, significant deviation from the
prescribed site characterization will necessitate re-evaluation and possible EMP revision.
Communication from the SSO will initiate the re-evaluation process by the Project Manager.
3.3 SAFETY DATA SHEETS (SDS)
Consistent with 29 CFS 1910.1200, (Hazard Communication Standard) applicable Safety
Data Sheets (or equivalent) will be kept on-site, in each vehicle, and with the Project
Manager. All subcontractors must ensure that their employees are informed of their rights
and responsibilities under the OSHA Hazard Communication Standard. Subcontractors will
provide SDS sheets for items which they bring on the site, as applicable. Due to the presence
of VOCs, 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
7
be re-evaluated.
4.0 AIR MONITORING
The purpose of air monitoring during subsurface investigation activities is to identify and
quantify airborne contaminants to determine the level of protection needed. Should air
monitoring for airborne contaminants be necessary, air monitoring with direct reading
instruments will be conducted during all intrusive activities. Four categories of air monitoring
will be conducted as follows:
· Breathing Zone Monitoring
· Explosive Gas Source Monitoring
· Work Area Monitoring
· Dust Monitoring
Equipment to be used in conducting air monitoring activities, along with a description of the
type and frequency of monitoring and associated action levels are discussed in the
paragraphs to follow. It should be noted that the contractors working in active construction
zones, including but not limited to excavations, trenches, bore holes, etc should be
responsible for proper air monitoring of these areas. However, should CES feel the need to
perform additional air monitoring, the following procedures (as outlined in sections 4.0
through 6.0, and to an extent, sections 7.0 through 11.0) may be implemented.
4.1 MONITORING EQUIPMENT
If CES employees are working in, or near, active construction zones where the potential
exists for chemical hazards and exposures to be present, the breathing zones will be
monitored using a MiniRAE portable VOC monitor. These instruments use a photoionization
detector that is designed to measure trace quantities of VOCs with a parts-per-million (ppm)
sensitivity range. It does not detect methane. The survey instrument will be calibrated using
an appropriate standard according to manufacturer’s instructions. The VOC monitor will be
calibrated prior to each use if the instrument is used infrequently, or daily when in constant
use.
If the MiniRAE portable VOC monitor detects elevated levels of VOC concentrations (> 50
ppmv), in ambient air at the site, a Gastech 02 /explosion/H2S meter will be used to measure
oxygen concentrations, explosion potential, and hydrogen sulfide (H2S) concentration. The
8
instrument will be calibrated with methane and H2S according to the manufacturer’s
instructions.
Air monitoring equipment will be certified intrinsically safe and operated by personnel trained
in the use of the specific equipment provided.
4.2 TYPES AND FREQUENCY OF MONITORING
4.2.1 Breathing Zone Monitoring
The breathing zone of a representative employee suspected of greatest exposure for each
job category engaged in work with potentially hazardous substances will be monitored as
follows:
· For excavation operations, monitor the breathing zone of the
equipment operator and laborers with an OVM when the waste
material is initially exposed. The results of the monitoring, the
employee’s name, and the work activity will be recorded in the
daily log
4.2.2 Explosive Gas Source Monitoring
During all operations identified as having a fire/explosion hazard, a combustible gas meter
set to measure the lower explosive level (LEL) will be used to continuously monitor the top of
the trench or excavation.
4.2.3 Work Area Monitoring
Each work area associated with hazardous waste spills and/or contamination will be
monitored at least one time each day with an OVM to determine the concentration of
contaminants being released into the general area.
4.2.4 Dust Monitoring
Chemical exposure via inhalation will be mitigated through the evaluation of wind velocity,
and common sense. Personal protective equipment will be utilized as necessary (based on
specific action levels) to prevent chemical exposure in excess of the exposure limits.
When possible, personnel should be situated upwind of work activity when working at the
site. Excavated areas should be allowed to vent for one to two minutes prior to investigative
9
activities to allow any vapors, dusts, or gases to dissipate. Liquids and solids should never
be smelled to confirm the presence or absence of chemicals.
The SSO or CES representative will screen the site for dusty conditions to prevent inhalation
of chemicals in particulate form (e.g. residue on soil grains). If dusty conditions are observed,
all workers will wear appropriate respiratory protection designed for dusts. Extremely dusty
conditions may require dust suppression via water mist or spray prior to returning to work.
4.3 ACTION LEVELS
The action levels as prescribed by the National Institute for Occupational Safety and Health
(NIOSH) will be used to initiate protective actions including, but not limited to, use of personal
protective devices, shut down of specific work activities, and site evacuation. A current
volume of the NIOSH Pocket Guide (electronic version) to Chemical hazards will, or may be
utilized as an on-site referenced by the SSO.
5.0 PERSONAL PROTECTIVE EQUIPMENT AND PROCEDURES
5.1 RESPIRATORY PROTECTION
During excavation or construction activities in an area where special wastes are expected or
have been encountered, the use of respiratory protection equipment may be required.
Respiratory protection is of primary importance as inhalation is one of the major routes of
exposure to chemical toxicants. Respiratory protective devices include air purifying
respirators, air-line respirators, and self-contained breathing apparatus.
The following respiratory protection practices will be observed by all workers at the Site when
conditions warrant respiratory protection:
· The respiratory protection utilized on-site will be in accordance
with OSHA, 29 CFR 1910.134
· Only properly cleaned, maintained, NIOSH/MSHA-approved,
respirators will be used on-site (if required)
· Selection of respirators, as well as any decisions regarding
upgrading or downgrading of respiratory protection, will be
10
made by the SSO
· Air-purifying cartridges will be replaced on a regular basis (at
least once per day) as determined by the SSO
· No employee will be assigned to tasks requiring the use of
respirators if, based upon the most recent examination, a
physician determines that the employee will be unable to
function normally wearing a respirator or that the safety or
health of the employee or other employees will be
compromised by use of a respirator
· Persons required to wear full-face respirators must not have
beards or moustaches that interfere with proper respirator seal.
All personnel wearing full-face respirators or personnel working
in the exclusion zone will be required to be clean-shaven prior
to each day’s shift. This will be strictly enforced by the SSO
· All personnel required to use APRs must be properly fit tested
prior to engaging in field activities in accordance with OSHA
standards (29 CFR 1910.1025)
5.2 PROTECTIVE CLOTHING
To protect workers against dermal contact with contaminants, the following apparel must be
worn during site-specific work activities depending on the level of protection specified for
those activities (Section 5.3 of this EMP):
· Disposable Tyvek coveralls
· PVC-coated or equivalent coveralls for splash protection

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)

· Tape gloves and boots to coveralls to prevent leakage
· Hearing protection (as determined by SSO)
5.3.4 Level B Protection
Level B will be used for site work when inhalation and dermal contact hazard are elevated to
the point that a positive pressure, supplied air source is needed.
· Saranex coveralls/chemical-resistant clothing
· Gloves (inner latex gloves and outer nitrile gloves)
· Hard hat
· Self-contained breathing apparatus (SCBA), or Supplied Air-
Line Respirator (SAR)
· Chemical-resistant safety boots
· Gloves and boots taped to prevent leakage
6.0 SITE CONTROL
13
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.
Support Zone. This zone covers all areas outside of the
14
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
· Field personnel must observe each other for signs of exposure.
15
Indications of adverse effects include, but are not limited to, the
following:
- Changes in complexion and skin
discoloration
- Changes in coordination
- Changes in demeanor
- Excessive salivation and
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
times (when not prohibited by the use of air purifying
respirators). Wear other protective gear as specified in the
Health and Safety Plan
· A closed cab or cage will be required for equipment used at the
16
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
· Be sure that no underground or overhead power lines, sewer
17
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).
Packaging of Waste Items – All disposable clothing and other contaminated material will be
18
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

21
safety training as approved and/or provided by CES, the Owner, the Contractor, or if required,
by 3rd party General Contractor.
9.2 SITE-SPECIFIC TRAINING
Employees assigned to the site may, as needed, be given site-specific training and field
experience to include the following topics:
- Acute and chronic effects of the toxic chemicals found at the site
- Routes of potential exposure and field activities which could result in such
exposure
- Need for personal protection, types of protection, fit effectiveness and
limitations
- Medical surveillance program

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
22
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
12.1 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
or Dawn Crowell and the Local Fire / Emergency Management agency (Davidson County
Emergency Services at 336.242.2270).
