CES Project No. 7919.0522E Page 3 February 3, 2023 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. CES Project No. 7919.0522E Page 5 February 3, 2023 3.0 SCOPE OF SERVICES The scope of services for this report were authorized by NCDEQ Task Authorization (TA) #03, approved on November 21, 2022, under CES Contract Number N040722, dated April 20, 2022. In accordance with the approved TA, the scope of services included the following:  Install up to one groundwater monitoring well along the southern property boundary to an approximate depth of 35-feet below grade;  Monitor and collect one soil sample during the installation of the new monitoring well for laboratory analysis of 8260, including MTBE and IPE, and MassDEP VPH;  Monitor and collect groundwater samples from up to two monitoring wells (MW-5 and MW-6) for laboratory analysis by Standard Method (SM) 6200B, including MTBE, IPE and EDB, EPA 625 BNA and MassDEP VPH and EPH; and  Prepare and submit one groundwater monitoring report summarizing the field and laboratory analytical findings. CES Project No. 7919.0522E Page 6 February 3, 2023 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. 4.1 UST Owner and Operator Information UST Owner/Operator: Monroe Snyder (deceased) Address: 1301 Bringle Ferry Road, Denton, NC 27239 Phone: N/A Person Associated With Release: (Site accepted into State-Lead Acceptance Program) Address: N/A Phone: N/A *Current Property Owner: Harold & Betty Ruth Myers Address: PO Box 1205, Lexington, NC 27293 Phone: N/A *Information retrieved from the Davidson County GIS Real Estate System On April 26, 2022, the site was accepted into the NCDEQ State-Lead Acceptance Program to conduct further investigative measures relative to Incident Number 14039. Additional responsible party information is provided in Table B-1 and Table B-2, and above in Section 1.2. CES Project No. 7919.0522E Page 7 February 3, 2023 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. A general summary of the UST system is presented below, with further information included in Tables B-1 and B-2: UST ID No Current/Last Contents Capacity (gallons) Date Installed Permanently Closed Discovery of Release 1 Gasoline 6,000 5/13/1964 No Yes 2 Gasoline 6,000 5/13/1964 No Yes 3 Gasoline 6,000 5/13/1964 No Yes 4 Waste Oil (Or Diesel) 550 5/8/1994 8/30/1999 Yes (Incident No. 20707) 5 Presumed Heating Oil Unknown Unknown Unknown Unknown The approximate locations and orientation of the USTs are depicted on Figure 2. 4.3 Non-UST Information One above ground storage tank (AST) was identified onsite during the LSA completed in July of 2022, and is summarized below: AST ID No Current/Last Contents Use Secondary Containment Location 1 Presumed Heating Oil Heating Oil No Adjacent to SE corner of onsite building extension The approximate location of the AST is depicted on Figure 2. 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. 5.5 Summary of Soil, Groundwater, Surface Water and Free Product Assessment Information 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: 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 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.

CES Project No. 7919.0522E Page 17 February 3, 2023 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.

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. 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 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 Scientist: Dawn Crowell, MELP CES Group Engineers, LLP 3525 Whitehall Park Drive, Suite 150 Charlotte, NC 28273 980.222.0206 (direct) 551.333.4787 (mobile) 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 · Nitrile gloves or equivalent · Inner gloves - latex or vinyl · Outer disposable boots · Hard hat · Chemical-resistant boots (Neoprene, PVC, or equivalent) 11 · Hearing protection (as applicable) · Steel-toed safety shoes · Goggles or safety glasses will be worn at all times in the work area · Sleeves taped to gloves and cuffs taped to boots · Face shield attachments for use with hard hats · Disposable, chemical-resistant outer boots Upgrading or downgrading selected protective equipment will be the decision of the SSO based on assessment of exposure potential during specific tasks. 5.3 LEVELS OF PROTECTION The levels of protection to be utilized at the site, and the activities to which they apply, are described in the following paragraphs. The SSO will select the appropriate level of PPE based on air monitoring results. 5.3.1 Modified Level D This is the minimum level of protective clothing to be worn at the site during subsurface investigation activities. All workers, supervisors, and visitors will be required to don the following clothing prior to entering the project site. Based on the anticipated activities to be performed at the site, it is anticipated that Modified Level D will provide adequate protection coverage. · Work clothes · Hard hat · Safety shoes · Visibility vest · Work gloves (only as necessary) 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)* 12 · Safety shoes · Nitrile gloves* * 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 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.

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 19 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.

In general, vehicles, equipment, and materials brought into the Exclusion Zone will remain in the Exclusion Zone until no longer necessary to the project. 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 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 - 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 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 - 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 28 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 Scientist (Dawn Crowell). 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 29 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) SSO (if assigned by Dawn Crowell, CES Group Engineers And/or by Env PM) Carolina Soil Investigations 704.539.5279 (Assigned CSI field crew chief) Back-up PM Dawn Crowell 551.333.4787 (M) CES Group Engineers, LLP 980.222.0206 (D) Police: North Carolina Highway Patrol 911 Lexington Police Department 336.243.3302 Hospital: Atrium Health Wake Forest Baptist | Lexington Medical Center 336.248.5161 250 Hospital Drive Lexington, NC 27292 Fire: City of Lexington Fire Department Station 336.248.3935 Doctor: Atrium Health Wake Forest Baptist | Lexington Medical Center 336.248.5161 Ambulance 911 NCDENR (Winston-Salem Region) 336.776.9800 Directions to the nearest hospital: Atrium Health Wake Forest Baptist | Lexington Medical Center, 250 Hospital Drive, Lexington, NC 27292. Refer to Appendix C. 30 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).
