CES Project No. 8149.0523E 6 August 17, 2023 2.0 EXECUTIVE SUMMARY The purpose of this Phase I Limited Site Assessment (LSA) is to provide the information necessary for the North Carolina Department of Environmental Quality (NCDEQ) to evaluate the level of risk to human health and the environment resulting from the apparent release of petroleum-related constituents from the historical operation of an underground storage tank (UST or tank) system (removed in October 1992), located at Bost Realty, 806 S Main Street, Kannapolis, Cabarrus County, North Carolina (hereafter identified as the site, subject site, subject property or property). The site location, including topographic features, is depicted on Figure 1. CES Group Engineers, LLP (CES) has been authorized to perform this LSA by NCDEQ, represented by Scott Ryals, PE, Environmental Engineer. A Phase I LSA of the subject property was completed by CES to evaluate if soil and groundwater has been impacted at the site by the apparent release condition, and if the potential exists for nearby water supply wells and/or other receptors to be impacted. In October of 1992, a total of three gasoline USTs were removed from the site by a local backhoe operator (Carolina Tank Services), while under the direction of the property and business owner at that time. Two 550-gallon USTs and one 10,000-gallon UST were removed and disposed of offsite. Upon removal of the USTs, six soil samples were collected from beneath the three removed USTs and one soil sample was collected at the location of the fuel dispenser area by a representative of Carolina Tank Services. Two soil samples from each UST location were collected from the base of the excavated area, with one soil sample (B-2) reporting a total petroleum hydrocarbons (TPH) concentration of 33 parts per million (ppm), with the other soil samples reporting non-detect TPH concentrations. The soil sample (Island) collected from the location of the fuel dispenser area reported TPH concentrations of 27 ppm. Limited information regarding the release conditions, history, and/or release characteristics was made available to CES. Copies of historical site records, including information relative to the removal of the USTs in October of 1992, as retrieved from NCDEQ’s UST Incident weblink, tank and owner databases, are included in Appendix A. Based upon the listed date of discovery of October 8, 1992, as referenced in Section 1.3 of this report, it is presumed that NCDEQ subsequently issued Incident Number 15803 for an apparent release condition identified during the removal of the three gasoline USTs in October 1992. Since the completion of the UST removal and soil sampling, no further assessment, monitoring and/or remediation activities are known to have taken place at the site. On June 9, 2023, under the direction of CES, one (1) soil boring was installed on the eastern side of the site, near the former 550-gallon USTs, and the approximate soil sample (B-2) location that was collected following the UST removals in October of 1992, and subsequently converted to a 2-inch diameter permanent groundwater monitoring well (MW-1) to facilitate the collection of groundwater samples for laboratory analysis. During the installation of groundwater monitoring well MW-1 on June 9, 2023, one soil sample was collected immediately above the water table, at a depth of approximately 13-feet below grade, placed in laboratory provided vials and glassware, stored on ice, and hand delivered under chain- of-custody (COC) procedures on June 9, 2023 to Waypoint Analytical (Waypoint) of Charlotte, North Carolina (NC Certification No. 402) for laboratory analysis of VOCs by 8260, sVOCs by 8270, Metals (Pb & Cr) and VPH and EPH by MassDEP methodologies. Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent CES Project No. 8149.0523E 7 August 17, 2023 concentrations above the Soil to Water Maximum Soil Contaminant Concentration (MSCC):  MW-1: chromium (15.8 mg/kg) All other concentrations of petroleum-related constituents in soil were reported below Soil to Water MSCC, Residential Soil Cleanup Levels, and Industrial/Commercial MSCC from MW-1. Upon completion of the soil boring to a depth of approximately 35-feet below grade, after depth to groundwater was estimated between 15 and 20-feet below grade, and subsequent conversion to a 2-inch diameter permanent monitoring well, depth to groundwater (DTW) measurements were recorded using a water level meter capable of detecting light non-aqueous phase liquid (LNAPL or Free Product) to an accuracy of 0.01 feet. Free product was not detected in MW-1. A DTW measurement from MW-1 was recorded at a depth of 18.5-feet below grade. Groundwater samples were then collected from MW-1, placed on ice, and delivered under COC procedures to Waypoint on June 9, 2023, for analysis of VOCs by 6200B and 504.1, Base/Neutrals and Acids by 625, Metals (Pb & Cr) and VPH and EPH by MassDEP methodologies. Groundwater laboratory analytical results from MW-1 reported the following petroleum-related constituent concentrations above the 2L Standards:  MW-1: 1,2-dibromoethane No concentrations of petroleum-related constituents in groundwater were reported above the Gross Contaminant Level (GCL). All other concentrations of petroleum-related constituents in groundwater were reported below 2L Standards and the GCL from MW-1. Municipal water distribution systems provided by the City of Kannapolis serve the subject property and surrounding properties. No water supply wells or/or other receptors were identified within 1,500-feet of the site. Based upon soil concentrations reported above appliable Soil Standards, and groundwater concentrations reported above the 2L Standards but below the GCL, without the foreseeable risk of impacting nearby receptors, without the presence of any know or report water wells in the general vicinity of the site, it is of 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. CES Project No. 8149.0523E 8 August 17, 2023 3.0 SITE HISTORY AND CHARACTERIZATION The subject site where this LSA was performed, where an apparent release of petroleum-related constituent occurred, consists of one parcel, identified as Cabarrus County Parcel Identification Number (PIN) 56135532210000, and is situated at the intersection of S Main Street and Bethpage Road, as shown on Figure 1.

CES Project No. 8149.0523E 13 August 17, 2023 5.0 RECEPTOR INFORMATION 5.1 Water Supply Wells As part of this LSA, a water supply well survey was conducted by interviewing the owner of the subject property, conducting a windshield survey, and sending out Request for Water Supply Well Information forms to property owners located within a 500-feet radius of the subject property. According to information obtained from the subject property owner, nearby and surrounding property owners, a review of NCDEQ SWAPInfo 2.0 and the City of Kannapolis and Cabarrus County GIS systems, no water supply wells are known to exist within a 1,500-feet radius, as municipal water distribution systems serve the subject property and surrounding properties. On June 14, 2023, CES sent out Request for Water Supply Well Information forms to 50 properties within a 500-feet radius of the subject property. A total of 7 Water Supply Well Information forms were returned to CES, or information was otherwise communicated to CES, which did not report the presence of water supply wells within a 500-feet radius of the site. Table B-5 summarizes public and private water supply well information. 5.2 Public Water Supplies According to the NC SWAPInfo 2.0 Map and NC One Map - Public Water Supply Water Resources Map, no public water supply wells are known to exist within a 1,500-feet radius of the subject property. Municipal water distribution systems provided by the City of Kannapolis are available to serve the subject property and surrounding properties. 5.3 Surface Water According to the NC One Map – Surface Water Classifications Map, Threemile Branch Creek is located approximately 1,500-feet east of the site, and an unnamed creek that flows into Irish Buffalo Creek located approximately 1,700-feet west of the site. According to the NC One Map – Surface Water Intakes Map, no surface water intakes are located within a 1,500-foot radius of the subject site. 5.4 Wellhead Protection Areas According to the NC SWAP website and database of approved North Carolina Wellhead Protection Areas, no wellhead protection areas and/or approved wellhead protection plans are known to exist in Cabarrus County. 5.5 Deep Aquifers in the Coastal Plain Physiographic Region Not applicable to the subject site, as the site lies within the Piedmont Physiographic Region. CES Project No. 8149.0523E 14 August 17, 2023 5.6 Subsurface Structures Underground utilities have been identified at and adjacent to the subject site, and the potential exists for soil and groundwater contamination to be in contact with these underground utilities. Groundwater has historically been measured at approximately 18.5-feet below ground surface at the site. Because the underground utilities are expected to be at a shallower depth than 18.5- feet, the utility lines would not be considered receptors or conduits for ground water contaminant migration. No subsurface structures have been identified at the site. Figure 5 depicts a 1,500-feet Potential Receptor Map. CES Project No. 8149.0523E 15 August 17, 2023 6.0 LAND USE 6.1 Property Owners and Occupants Land use in the vicinity of the subject property can be characterized as commercial, residential, and institutional uses. Based on petroleum-related constituents reported above applicable groundwater standards (2L Standard), nearby and surrounding property owners and occupants may be impacted by the apparent release from Incident Number 15803, should the contaminant plume happen to extend beyond the subject property. Table B-6 summarizes contiguous property owners and occupants. No sensitive land use features, such as schools, daycare centers, nursing homes, hospitals, playgrounds, churches, camps, or other places of assembly, have been identified within 1,500- feet of the source of the release, with the exception of the Midway United Methodist Church, located approximately 200-feet to the north, Imperial Health Services located approximately 550- feet to the northeast, and First Wesleyan Church located approximately 1,000-feet to the west. Aerial imagery depicting land use in the general vicinity of the site is included on Figure 5. CES Project No. 8149.0523E 16 August 17, 2023 7.0 SITE GEOLOGY AND HYDROGEOLOGY According to the Geological Map of North Carolina (1985), the subject site is located within the Piedmont Physiographic Province, is underlain by intrusive rocks of the Charlotte and Milton Belts and is within a metamorphosed granite rock formation. A description of the underlaying Rock Unit CZv is interbedded felsic to mafic tuffs and flowrock. 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 (CeB), which generally have a 2 to 10 percent slope, and are classified as well drained sandy clay loam (0 to 6-inches), clay (6 to 40-inches), clay loam (40 to 48-inches), and sandy loam (48 to 80-inches). Parent materials were classified as Saprolite derived from granite and gneiss, and/or schist. Encountered soils from monitoring well MW-1 were generally classified as brown clayey silt. According to a review of applicable USGS topographic mapping for the subject property and onsite observations, it has been determined that natural surface drainage in the vicinity of the subject site is generally in an east-southeasterly direction. While not always the case, groundwater flow direction typically follows the direction of surface water flow, and is, therefore, anticipated to flow east-southeasterly. Man-made improvements may alter natural local drainage patterns to some degree. The data obtained and reported herein is representative of conditions only at the referenced boring and monitoring well location, and is not necessarily indicative of conditions elsewhere on the subject property. CES Project No. 8149.0523E 17 August 17, 2023 8.0 SAMPLING RESULTS 8.1 Phase I Investigation On June 9, 2023, under the direction of a CES environmental scientist, one soil boring was installed on the eastern portion of the site, in the area of the former gasoline USTs, to a depth of approximately 35-feet below grade, after depth to groundwater was estimated at between 15 to 20-feet below grade, to facilitate the completion of one 2-inch diameter permanent groundwater well (MW-1) for groundwater collection purposes. Soil boring/monitoring well MW-1 was installed by a sub-contracted driller, Carolina Soil Investigations, LLC of Olin, North Carolina, via augering techniques, utilizing a track-mounted geoprobe rig, Model 6712DT. Prior to the completion of MW-1, Monitoring Well Construction Permit Number WM0301285 was obtained from the Water Quality Regional Operations Section of the NCDEQ Division of Water Resources. During the advancement of the soil boring, subsurface soils were primarily classified as brown clayey silt from grade to approximately 35-feet below grade, with moist samples observed at a depth of approximately 15 to 20-feet below grade. The Site Plan, as shown on Figure 2, depicts the location of monitoring well MW-1. A monitoring well construction log and drilling form for the soil boring/monitoring well are included as Table B- 7 and Appendix E, respectively. The Monitoring Well Construction Permit is included in Appendix E. During the advancement of the soil boring, the CES Environmental Scientist field screened encountered soils with a MiniRAE 2000 Photoionization Detector (PID) for the presence of volatile organic compounds (VOCs), reported in parts per million per volume (ppmv), to facilitate the selection of one soil sample for subsequent laboratory analysis. PID measurements were recorded at non-detect (i.e., ND, or 0.0 ppmv) levels from grade to approximately 20-feet below grade when groundwater was encountered. . Based on PID measurements and the approximate depth of encountered groundwater (between 15 to 20-feet below grade), the soil sample at a depth of approximately 13-feet below grade was collected in laboratory provided vials and glassware, stored on ice, and hand delivered under COC procedures on June 9, 2023, to Waypoint for laboratory analysis of the following:  VOCs by 8260 + MTBE/IPE  sVOCS by 8270 BNA  MassDEP VPH  MassDEP EPH  Metals: Pb + Cr Soil laboratory analytical results from MW-1 reported the following petroleum-related constituent concentrations above the Soil to Water MSCC:  MW-1: chromium (15.8 mg/kg). All other concentrations of petroleum-related constituents in soil were reported below Soil to Water MSCC, Residential Soil Cleanup Levels and Industrial/Commercial MSCC from MW-1. A photographic log depicting the site and soil boring location is included in Appendix B. Figure CES Project No. 8149.0523E 18 August 17, 2023 2 depicts the location of soil boring/monitoring well MW-1. Figure 3 depicts a Soil Concentration and Estimated Extent of Contamination Map. Table B-3 summarizes soil laboratory analytical results. Soil laboratory analytical reports are included in Appendix D. Upon completion of the soil boring to a depth of approximately 35-feet below grade, and subsequent conversion to a 2-inch diameter monitoring well, DTW measurements were recorded using a water level meter capable of detecting LNAPL to an accuracy of 0.01 feet. LNAPL was not detected in groundwater monitoring well MW-1. DTW measurement from MW-1 was recorded at a depth of approximately 18.5-feet below grade. After collecting depth to groundwater measurements, and after calculating the volume of water to be removed from MW-1, a dedicated 1.5-inch disposable bailer was used to develop the well by surging methods, and then approximately three to five well volumes were purged from the monitoring well. Groundwater samples were then collected in laboratory provided vials and glassware via the dedicated 1.5-inch disposable bailer, stored on ice, and hand delivered under COC procedures on June 9, 2023, to Waypoint for laboratory analysis of the following:  VOCs by SM 6200B ext + 5 oxy  VOCs by 504.1 (EDB)  Base/Neutrals and Acids by 625 BNA  MassDEP VPH  MassDEP EPH  Metals: PB + Cr Groundwater laboratory analytical results from MW-1 reported the following petroleum-related constituent concentrations above the 2L Standards:  MW-1: 1,2-dibromoethane No concentrations of petroleum-related constituents in groundwater were reported above the GCL. All other concentrations of petroleum-related constituents in groundwater were reported below 2L Standards and the GCL from MW-1. . Figure 4 depicts a Groundwater Elevation and Estimated Extent of Contamination Map. Tables B-4 and B-9 summarize groundwater analytical results and depth to groundwater measurements, respectively. Field data sheets for groundwater sampling, along with CES’ standard operating procedures for soil and groundwater investigations, and the prepared and reviewed Job Hazard Analysis (JHA) and Emergency Management and Health & Safety Plan (HASP) are included in Appendix C. Groundwater analytical reports are included in Appendix D. CES Project No. 8149.0523E 19 August 17, 2023 9.0 CONCLUSIONS AND RECOMMENDATIONS 9.1 Conclusions and Recommendations Conclusions: A Phase I LSA of the subject property was completed by CES to evaluate if soil and groundwater has been impacted at the site by the apparent release condition from the historical operation of the UST system (removed in October 1992), and if the potential exists for nearby water supply wells and/or other receptors to be impacted. Subsequent findings indicated that a soil sample collected from a soil boring/monitoring well (MW- 1) installed on the eastern portion of the site, in the area of the former gasoline USTs, reported concentrations of petroleum-related constituents (chromium) above NCDEQ Soil Standards, and subsequent groundwater samples collected from MW-1 reported concentrations of petroleum- related constituents (1,2-dibromoethane) above 2L Standards, but below the GCL. The findings of the receptor survey indicated that no known or reported water supply wells have been identified in the general vicinity of the site. Recommendations: Based upon laboratory analysis of soil and groundwater samples collected from MW-1 on June 9, 2023, reporting petroleum-related constituents above applicable soil and groundwater standards, including groundwater concentrations of 1,2-dibromoethane reported above the 2L Standard but below the GCL, it is of the opinion of CES that the Site Risk/Ranking is considered to be low, and without the foreseeable risk of impacting nearby receptors because of no known or reported water wells in the general vicinity of the site, it is the opinion of CES that a Notice of Residual Petroleum (NRP) can be placed on the property. However, during any potential and/or future site redevelopment activities, property transactions, and/or site improvements, it is the recommendation of CES that additional soil, groundwater and vapor assessment, monitoring and remediation activities be conducted at the site, as the data obtained and reported herein is representative of conditions only at the referenced boring and monitoring well location (MW-1), and is not necessarily indicative of conditions elsewhere on the subject property.

For the purpose of this plan, the term “project” references “NCDEQ MO-4731_15803”. 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. 2 As part of CES’ safety program, a site-specific Job Hazard Analysis (JHA) form will be used, in conjunction with this plan, which will also include the name, address, and telephone number of the nearest hospital in relation to the project address where work is being completed. CES personnel have been instructed to utilize 911 as the first call should an accident, or issue, be apparent that warrants an immediate emergency response action. This plan is intended for general use during subsurface investigation activities completed by CES personnel, or CES subconsultants/subcontractors, and as a general reference for workers to review and understand the potential environmental and health and safety conditions that may be present under normal subsurface investigation conditions. Additionally, this plan should also be utilized for any work completed at surrounding properties where subsurface investigation activities are, or may be required. Prior to initiating subsurface investigation activities, as those referenced above, CES personnel (Project Manager(s), Site Safety Officer, and/or Field Crews) will complete Job Hazard Analysis (JHA) and selected CES safety forms which detail job specifics, including the sequence of basic job steps, potential incidents or hazards, and recommended procedures to eliminate potential incidents or hazards. 1.1 PURPOSE / OBJECTIVE The protection of workers and environmental safety and health are major concerns during this project and cannot be understated. The objective of the EMP is to document procedures and precautions to be implemented during any geophysical investigations and installation of soil borings with conversion to permanent monitoring wells, and site assessments, including soil and groundwater monitoring and/or remediation activities, in order to provide for and promote safe working conditions at the site during field activities, specifically at locations where contamination of soil and groundwater has been documented and/or is expected to be encountered. The safety organization and procedures have been established based on a previous analysis of potential hazards at the site. Personal protection measures have been selected in response to these potential hazards. This EMP and HASP has also been developed based upon review of the requirements described in the U.S. Environmental Protection Agency (USEPA) Standard Operating Safety Guide and the U.S. Department of Labor OSHA standards 29 CFR Part 1910. Reasonable precautions will be taken by the contractor’s representative and its subcontractors to provide for and promote the safety and health of workers and the general public. Subcontractors will 3 be given copies and will be required to follow this EMP. 1.2 RESPONSIBILITIES FOR HEALTH AND SAFETY All site activities which have the potential to expose personnel to site contamination or a related injury are subject to this EMP. Personnel will be responsible for adherence to the safety procedures during the performance of the work. In no case may work be performed in a manner that conflicts with the intent of, or the inherent safety and environmental cautions expressed in, these procedures. Following due warning(s), personnel who violate safety procedures will be dismissed from the site, and may be terminated. In the event that contamination is encountered during regular construction operations, personnel will be exclusively employed in the affected area of the project site, who have been properly trained in health and safety regulations associated with handling hazardous materials or special wastes as specified in the training section (Section 9.0) of this EMP. The requirements provided herein may be modified as the work progresses to accommodate changing conditions, but a reduction or increase in the health and safety requirements will not be made without prior approval by the assigned Site Safety Officer (SSO). The prevention of adverse health effects and injuries to site workers is totally dependent on the contribution of all project participants. Open communication among workers, supervisors, and management concerning safety at the site is an essential element of this EMP. 1.3 SUBCONTRACTOR’S RESPONSIBILITY The Subcontractor is solely responsible for the health, safety, and protection of their own on- site personnel during the performance of the survey services work scope. The Subcontractor will perform the work specified in the contract documents in accordance with the HEALTH AND SAFETY REQUIREMENTS specified herein, and federal, OSHA, state, and local health and safety regulations. It will be the responsibility of the Subcontractor to be familiar with the required health and safety regulations in the performance of this work. The Subcontractor will designate a Site Safety officer to implement and monitor activities related to this EMP. Should any unforeseen or site-specific safety-related factor, hazard, or condition become evident during the performance of the work, the Subcontractor will take immediate and prudent action to establish and maintain safe working conditions and to safeguard site personnel, the public, and the environment. 4 2.0 ASSIGNMENT OF RESPONSIBILITY All site activities which have the potential to expose CES personnel to site contamination or related injury are subject to this EMP. As previously discussed, all site personnel are responsible for adherence to the safety procedures during performance of the work. Specific oversight responsibilities are assigned to various personnel as discussed in the paragraphs to follow. 2.1 SITE SAFETY OFFICER The SSO will be assigned to monitor the daily activities to assure that all health and safety procedures/policies are being followed by CES personnel. This includes communicating the specific requirements to all personnel, including subcontractors, implementing the EMP, conducting site inspections to monitor compliance with EMP as required, providing or coordinating training as required, coordinating the medical monitoring program, coordinating respirator fit tests as required, coordinating the acquisition, calibration and maintenance of air monitoring equipment, respirators and other safety equipment, directing on-site health and safety activities, and reporting safety related incidents or accidents to the Project Manager. The SSO for CES is: Greg Hans, PMP CES Group Engineers, LLP 3525 Whitehall Park Drive, Suite 150 Charlotte, NC 28273 704.325.5408 (direct) 617.828.9948 (mobile) It should be noted that the SSO may and will delegate responsibilities to a representative of CES, subconsultants and/or subcontractors working at the Site and offsite properties for any and all tasks associated with additional subsurface investigation activities. 2.2 PROJECT MANAGER(S) The project manager is ultimately responsible for ensuring that all project participants abide by the requirements set forth in this plan. Any and all changes in the scope of health and safety requirements or site characterization will be communicated from the Project Manager and/or Environmental Scientist/Engineer to the SSO. 5 Environmental Project Manager: Greg Hans, PMP CES Group Engineers, LLP 3525 Whitehall Park Drive, Suite 150 Charlotte, NC 28273 704.325.5408 (direct) 617.828.9948 (mobile) Environmental Engineer: Chuck Heleine, PE CES Group Engineers, LLP 3525 Whitehall Park Drive, Suite 150 Charlotte, NC 28273 704.308.7916 (mobile) 3.0 BACKGROUND AND HAZARD EVALUATION 3.1 PROJECT DESCRIPTION This project involves monitoring of potentially contaminated 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 11 · Goggles or safety glasses will be worn at all times in the work area · Sleeves taped to gloves and cuffs taped to boots · Face shield attachments for use with hard hats · Disposable, chemical-resistant outer boots Upgrading or downgrading selected protective equipment will be the decision of the SSO based on assessment of exposure potential during specific tasks. 5.3 LEVELS OF PROTECTION The levels of protection to be utilized at the site, and the activities to which they apply, are described in the following paragraphs. The SSO will select the appropriate level of PPE based on air monitoring results. 5.3.1 Modified Level D This is the minimum level of protective clothing to be worn at the site during subsurface investigation activities. All workers, supervisors, and visitors will be required to don the following clothing prior to entering the project site. Based on the anticipated activities to be performed at the site, it is anticipated that Modified Level D will provide adequate protection coverage. · Work clothes · Hard hat · Safety shoes · Visibility vest · Work gloves (only as necessary) 5.3.2 Level D Protection Level D protection includes chemical resistant gloves and will be used for site work whenever contact with contaminated equipment or materials is possible. The following clothing will be required for Level D: · Disposable, chemical-resistant outer boots · Coveralls (work uniform) · Hard hat · Eye protection (safety glasses, goggles, or face-shield)* · Safety shoes · Nitrile gloves* 12 * Optional, as determined by SSO Dust masks shall be used to reduce employee exposure to fugitive dust, an optional Level D device. The absence of dusty conditions at the site will be justification for the SSO to permit personnel to remove their masks. 5.3.3 Level C Protection Level C will be used for site work when the inhalation and dermal contact hazard is elevated. When conditions for Level C protection are appropriate, the following equipment will be required: · Tyvek coveralls/chemical-resistant protective coverall · Gloves (inner latex gloves and outer nitrile gloves) · Hard hat · Safety shoes · Full-face or half-face air purifying respirator with organic vapor cartridge (or other proper type cartridge for the intended use, as determined by the SSO) · Chemical-resistant outer boots · Tape gloves and boots to coveralls to prevent leakage · Hearing protection (as determined by SSO) 5.3.4 Level B Protection Level B will be used for site work when inhalation and dermal contact hazard are elevated to the point that a positive pressure, supplied air source is needed. · Saranex coveralls/chemical-resistant clothing · Gloves (inner latex gloves and outer nitrile gloves) · Hard hat · Self-contained breathing apparatus (SCBA), or Supplied Air- Line Respirator (SAR) · Chemical-resistant safety boots · Gloves and boots taped to prevent leakage 13 6.0 SITE CONTROL The purpose of site control is to minimize potential contamination of workers and to protect the surrounding area from hazards found at the site. If the project site is not secured by fencing or other suitable site control means and is not routinely patrolled by police or other independent security personnel; certain procedures must be followed to ensure suitable site control and limitation of access so that those persons who may be unaware of site conditions are not exposed to hazards. All excavations left open and unattended by site personnel will be appropriately barricaded and visibly posted with “No Trespassing” or other appropriate signage. All heavy machinery and equipment shall be locked or chained each evening upon completion of daily activities. All potentially contaminated media, such as soil, will be covered with plastic prior to leaving the site. 6.1 REGULATED AREAS As appropriate to the task conducted, the site vicinity will be divided into three zones to allow control of worker exposures. These zones are described as follows: · Exclusion Zone. This zone includes the actual area of contamination and localized work area where specific investigative and/or construction equipment is operating. This zone has the highest inhalation exposure potential, and/or presents a high probability of skin contact with cutaneous percutaneous - affecting chemicals. New exclusion zones may exist during certain site-specific activities. This will be defined by the SSO and access by individuals not necessary to operation will be limited. (Level D is minimum). · Contamination Reduction Zone. This zone includes the areas immediately surrounding the Exclusion Zone. All personnel and equipment leaving the Exclusion Zone shall be decontaminated in this zone. 14 Support Zone. This zone covers all areas outside of the Contamination Reduction Zone. Administrative activities are conducted in the Support zone, as well as equipment supply and first aid supply. It is essential that contamination be kept out of this zone. 6.2 ACCESS/SITE SECURITY Access to contaminated work areas (Exclusion and Contamination Reduction Zones) will be regulated and limited to authorized persons. Such persons include the Contractor’s employees, designated equipment operators, and designated union representatives, as applicable. The SSO will enforce access limitations during work hours. 6.3 POSTING/BARRICADES Warning signs will be posted and hung, as applicable, in readily visible locations in or near contaminated work areas. Barricades or barricade tape will be utilized to prevent access to various work areas as indicated above. 7.0 POLICIES 7.1 GENERAL WORK PRACTICES General work practices to be employed on-site are as follows: · At least one copy of this EMP will be available at the work site · 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 - 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 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 containers with plastic liners. During hot weather operations, a cool down station may be set up within this area. 2. Outer Garment, Boots and Gloves Wash and Rinse 2. Scrub outer boots, outer gloves and fully encapsulating suit with decon solution or detergent and water. Rinse off using copious amounts of water. 3. Outer Boot and Glove Removal 3. Remove outer boots and gloves. Deposit in container with plastic liner. 4. Tank Change 4. If worker leaves Exclusion Zone to change air tanks, this is the last step in the decontamination procedure. Worker’s air tank is exchanged, new outer gloves and boot covers donned, joints taped, and worker returns to duty. 5. Boot, Gloves and Outer Garment Removal 5. Boots, fully-encapsulated suit, inner gloves removed and deposited in separate containers lined with plastic. 6. SCBA Removal 6. SCBA backpack and facepiece is removed (avoid touching face with fingers). SCBA deposited on plastic sheets. 7. Field Wash 7. Hands and face are thoroughly washed. Shower as soon as possible. 19 EQUIPMENT NEEDED TO PERFORM MINIMUM DECONTAMINATION MEASURES STATION EQUIPMENT 1 A. Various Size Containers B. Plastic Liners C. Plastic Drop Cloths 2 A.

In general, vehicles, equipment, and materials brought into the Exclusion Zone will remain in the Exclusion Zone until no longer necessary to the project. 20 All contaminated vehicles and equipment will be decontaminated before they are taken off- site. The Contractor will provide and maintain the following facilities for equipment decontamination: - equipment decontamination pad - contaminated water collection system - high-pressure water or steam cleaners - trisodium phosphate detergent - wire brushes and scrapers 9.0 TRAINING 9.1 BASIC TRAINING All employees who will perform work at the site must have completed environmental and 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 - Work zones established at the site - Prohibited activities in the Exclusion and Contamination Reduction Zones - Engineering controls and safe work practices associated with each employee’s work assignment, including dust control measures - Personal and equipment decontamination procedures - Emergency response procedures - Basic operational safety, emphasizing hazards expected on-site - Drum handling procedures - Spill control - Sampling procedures - Site communication procedures 21 - 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 - Serious employee injury - Accumulation of combustible gases or vapors at concentrations greater than background - Oxygen concentration below 19.5% - Unsafe working conditions, such as inclement weather or hazardous material releases - Major release of toxic materials for which appropriate PPE is not being worn by workers 27 12.2 RESPONSIBILITIES The emergency coordinator is the SSO (Greg Hans) or assigned CES representative working onsite; the alternate or back-up is the Environmental Engineer (Chuck Heleine). The emergency coordinator is responsible for: - Assessing the situation and determining whether an emergency exists which requires activating the plan - Directing all efforts in the area, including evacuating personnel and minimizing property loss - Ensuring that outside emergency services such as fire departments, police, ambulance, and hospitals are notified when necessary - Directing the shut-down of site operations when necessary - Notifying regulatory agencies as necessary 28 12.3 EMERGENCY CONTACT LIST Emergency Contact Phone Number Environmental PM: Greg Hans, PMP 617.828.9948 (M) CES Group Engineers, LLP 704.325.5408 (D) Other SSO (if assigned by by Env PM) Carolina Soil Investigations (Drillers) 704.539.5279 (assigned CSI field crew chief) Back-up PM Chuck Heleine 704.308.7916 (M) CES Group Engineers, LLP Human Resources Taylor Ciucevich 704.325.5406 (D) CES Group Engineers, LLP Police: North Carolina Highway Patrol 911 Kannapolis Police Department 704.403.4800 Hospital: Atrium Health Kannapolis (24/7) 704.920.4000 2711 Lane Street Kannapolis, NC 28083 Fire: Kannapolis Fire Station #2 704.920.4260 (Main) Doctor: Atrium Health Kannapolis (24/7) 704.920.4000 Ambulance 911 NCDENR (Mooresville Region) 704.663.1699 Directions to the nearest hospital: Atrium Health Kannapolis, 2711 Lane Street, Kannapolis, NC 28083 Refer to Appendix C. 29 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.

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.

FIRE-FIGHTING MEASURES Suitable extinguishing media For small fires, Class B fire extinguishing media such as CO2, dry chemical, foam (AFFF/ATC) or water spray can be used. For large fires, water spray, fog or foam (AFFF/ATC) can be used. Firefighting should be attempted only by those who are adequately trained and equipped with proper protective equipment. Unsuitable extinguishing media Do not use straight water streams to avoid spreading fire. SDS ID NO.: 0156MAR019 Product name: Marathon Petroleum Benzene Page 3 of 10 Specific hazards arising from the chemical This product has been determined to be a highly flammable liquid per the OSHA Hazard Communication Standard and should be handled accordingly. Vapors may travel along the ground or be moved by ventilation and ignited by many sources such as pilot _____________________________________________________________________________________________ 0156MAR019 Marathon Petroleum Benzene Revision Date 05/14/2015 lights, sparks, electric motors, static discharge, or other ignition sources at locations distant from material handling. Flashback can occur along vapor trail. For additional fire related information, see NFPA 30 or the Emergency Response Guidebook 130. Hazardous combustion products Smoke, carbon monoxide, and other products of incomplete combustion. Explosion data Sensitivity to Mechanical Impact No. Sensitivity to Static Discharge Yes. Special protective equipment and precautions for firefighters Firefighters should wear full protective clothing and positive-pressure self-contained breathing apparatus (SCBA) with a full face-piece, as appropriate. Avoid using straight water streams. Water may be ineffective in extinguishing low flash point fires, but can be used to cool exposed surfaces. Avoid excessive water spray application. Water spray and foam (AFFF/ATC) must be applied carefully to avoid frothing and from as far a distance as possible. Keep run-off water out of sewers and water sources. Additional firefighting tactics FIRES INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after the fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles: if this is impossible, withdraw from area and let fire burn. EVACUATION: Consider initial downwind evacuation for at least 1000 feet. If tank, rail car or tank truck is involved in a fire, ISOLATE for 5280 feet (1 mile) in all directions; also, consider initial evacuation of 5280 feet (1 mile) in all directions. 6. ACCIDENTAL RELEASE MEASURES Personal precautions:Keep public away. Isolate and evacuate area. Shut off source if safe to do so. Eliminate all ignition sources. Protective equipment:Use personal protection measures as recommended in Section 8.

NFPA Health 2 Flammability 3 Instability 0 Special Hazard - SDS ID NO.: 0156MAR019 Product name: Marathon Petroleum Benzene Page 4 of 10 _____________________________________________________________________________________________ 0156MAR019 Marathon Petroleum Benzene Revision Date 05/14/2015 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. 8.

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. Sensitization Not expected to be a skin or respiratory sensitizer. Mutagenic effects May cause genetic defects. Carcinogenicity Cancer designations are listed in the table below Name ACGIH (Class) IARC (Class) NTP OSHA Benzene 71-43-2 Confirmed human carcinogen (A1) Carcinogenic to humans (1)Known to be human carcinogen Known carcinogen Reproductive toxicity None known.
