Yarmouth, MA 02664 File No. 2015.09 1.0 INTRODUCTION The subject property is located at 1282 Main Street (Route 28) in South Yarmouth, Massachusetts (the Site). The Site is occupied by the Jay Mart convenience store and sells gasoline and retail items. The store building is located in the northwest portion of the property. The majority of the Site is paved with landscaped areas to the south and east. In the eastern portion of the property there are three underground storage tanks (USTs) that contain gasoline and diesel fuel for retail sale. On December 6, 2002, a Release Notification Form and an Immediate Response Action (IRA) Plan and Status Report were submitted to the Massachusetts Department of Environmental Protection (MassDEP) due to increasing concentrations of MTBE in groundwater. The Site subsequently advanced through the Massachusetts Contingency Plan (MCP) program. Then on January 11, 2006, a Phase IV Remedy Implementation Plan (RIP) was submitted to the MassDEP. The RIP detailed a program of In -Situ bioremediation and groundwater monitoring. The Site is in Phase V of the MCP and the program includes In - Situ bioremediation and groundwater monitoring. Edge Environmental, LLC (Edge) was retained by Jay Mart to complete this Phase V Status and Remedial Monitoring Report. This Phase V Status and Remedial Monitoring Report was written to meet the requirements specified in 310 CMR 40.0892 of the MCP. This report was authorized by Mr. Jay Imad of Jay Mart, who has assumed responsibility for the release. Mr. Imad can be reached at 381 Camp Street, West Yarmouth, MA 02673, and (508) 726-2700. 2.0 SITE AND DISPOSAL SITE DESCRIPTION The Site is occupied by the Jay Mart convenience store and sells gasoline and retail items. The store building is located in the northwest portion of the property. There is no basement associated with the building. The majority of the Site is paved with landscaped areas to the south and east. The building is heated by a fuel oil fired boiler. There are three underground storage tanks (USTs) that contain gasoline and diesel fuel for retail sale in the eastern portion of the Site. The USTs are constructed with double -wall fiberglass -reinforced plastic. Theproperty is identified as Lot 132 on Assessor's Map 60 in the Town of Yarmouth Assessor's Office records. Refer to Figure 1 for a Site Locus Map and Figure 2 for a Disposal Site Plan. The Site is located above a medium yield aquifer in the Cape Cod area of Massachusetts and the area is considered a Sole Source Aquifer. Therefore, Groundwater Category GW-1 applies to the groundwater at the Site and the most stringent groundwater quality standards apply to the Site. Please see Figure 3 for a MassDEP Phase I Site Assessment Map, On October 18, 2002, a Notification of Responsibility for Release Tracking Number 4-17422 was issued to the Site because MTBE was detected in groundwater at increasing concentrations. On December 6, 2002, GeoInsight (GI) submitted a Release Notification Form and an Immediate Response Action (IRA) Plan and Status Report to the MassDEP. Based on the IRA Plan, additional soil borings were performed, two additional monitoring wells were installed and groundwater samples were collected. On January 11, 2006, a Phase IV Remedy Implementation Plan (RIP) was submitted to the MassDEP. The RIP called for In -Situ bioremediation and groundwater monitoring. Reportedly, Micro-Bac International, Inc. (MBI) M-IOOOBX formula microbes and Tri-Phasic 12 nutrient mix were used. The M-1OOOBX formula microbes were manufactured by for the remediation of gasoline constituents. The MBI formulation contains 8-12 strains of hydrocarbon degraders that will consume petroleum in aerobic and anaerobic environments. The liquid nutrients from MBI contain phosphates, potassium and nitrogen. The M-1000BX formula for gasoline dissolved in groundwater is reportedly a natural non-pathogenic, non -engineered biological product PO Box 5262 1 Manchester, NH 03108 1 Phone: 603-717-8808 Edge Environmental, LLC Consulting and Engineering www.EdgeEnviroLLC.com RTN 4-17422 Phase V Status & RMR Dec. 2022 — May 2023 Page 2 Mr. Jay lmad Jay Mart June 14, 2023 Gasoline Release 1282 Main Street, So. Yarmouth MA 02664 File No. 2015.09 that meets US EPA requirements for release into the environment. Copies of the technical data and Material Safety Data Sheets (MSDS) for the M-1000BX are included in Appendix B. On September 23, 2011, fifteen gallons of M-IOOOBX biological product and one gallon of the Tri-Phasic 12 nutrient were mixed together with 50 gallons of water following the manufacturer's recommendations. The 66 gallon mixture was then pumped into well MW-1. At the time of the injection, no LNAPL was detected in MW-1. Groundwater monitoring has been completed to document the performance of the Comprehensive Remedial Action. Please note that well MW-1 is the only monitoring well from which groundwater samples exceed the applicable standards. Refer to Appendix B for copies of prior groundwater monitoring tables. 3.0 INSPECTION AND MONITORING PERIOD ACTIVITIES The following groundwater monitoring was completed to document the performance of the Comprehensive Remedial Action. This report covers the period from December 2022 — May 2023. 3.1 December 21, 2022 On December 21, 2022, monitoring wells MW-1, MW-3, MW-101, ECS-1, ESC-2, ECS-3, ECS-4 and MW-C were gauged to determine the depth to water and light non -aqueous phase liquids (LNAPL or gasoline), if present, using an interface probe. The probe is capable of determining the depth to water or LNAPL to the nearest 0.01 foot. During the period, measurable LNAPL was not detected in the gauged monitoring wells. The depth to water in the release area ranged from approximately 18.55 feet in well MW-101 to 19.59 feet below the lip of the PVC in well MW-C. These depths were less than the depths gauged during the September 2022 gauging event. PIease refer to Table I for a summary of well gauging data. The selected well, MW-I, was then assessed for Monitored Natural Attenuation (MNA), by lowering a piece of clean low density polyethylene (LDPE) tubing into the well until the intake was set at approximately the middle section of the submerged well screen. A peristaltic pump was connected to the LDPE tubing, using new silicon tubing, to extract water from the well. The water was pumped from the well into a flow -through cell. A calibrated YSI Pro Quarto was sealed in the flow -through cell and was used to monitor the groundwater quality during pumping so that stabilization could be identified. Groundwater quality monitoring was performed on monitoring well MWA, and included pH, temperature, specific conductance, dissolved oxygen, and oxidation reduction potential. Water was extracted from the well at a pumping rate of approximately 200 ml/minute. The Monitored Natural Attenuation (MNA) results, for MW-1, after stabilization, are summarized as follows: • pH was 6.08 standard units; • Temperature was 14.2 degrees Celsius; • Specific conductance was 0.735 milliSiemens per centimeter; • Dissolved oxygen (optical) 0.99 milligrams per liter; and • Oxygen reduction potential was -32.4 millivolts. Please see Table 3 for a summary of the MNA data. A sample was collected from the well by pumping water from the tubing, prior to the flow through cell, into clean, laboratory provided, pre -preserved 40 ml VOA vials. The sample was chilled on ice and transported under chain -of -custody to Alpha Analytical, Inc. The sample was submitted for analysis extractable petroleum PO Box 5262 1 Manchester, NH 03108 1 Phone: 603-717-8808 Edge Environmental, LLC Consulting and Engineering www.EdReEnviroLLC.com RTN 4-17422 Phase V Status & RMR Dec. 2022 — May 2023 Page 3 Mr. Jay Imad Jay Mart June I4, 2023 Gasoline Release 1282 Main Street, So. Yarmouth, MA 02664 File No. 2015.09 hydrocarbons(EPH) and associated target analytes and for volatile petroleum hydrocarbons (VPH) and associated target analyte Analysis of the sample detected the VPH hydrocarbon fraction C9-C l0 aromatic hydrocarbons at a concentration above the applicable Method I Risk Characterization standard. Target analytes were not detected at concentrations at or above the applicable Method l Risk Characterization standards. These results were higher than the results from the September 2022 sampling event. Analysis of the sample detected the EPH hydrocarbon fraction C11—C22 aromatic hydrocarbons and 2- methylnaphthalene at concentrations above the applicable Method I Risk Characterization standard. Target analytes were not detected at concentrations at or above the applicable Method 1 Risk Characterization standards. The CI I—C22 aromatic hydrocarbon results are higher than the results from the November 2021 sampling event. The 2-methylnaphthalene results are lower than the results from the November 2021 sampling event. Please refer to Table 2 for a summary of groundwater analytical results and Appendix A for a copy of the laboratory analytical report. Refer to the attached graph for VPH changes over time. 3.2 March 27, 2023 On March 27, 2023, monitoring wells MW-1, MW-2, MW-3, MW-101, ECS-1, ESC-2, ECS-3, ECS-4 and M W-C were gauged to determine the depth to water and light non -aqueous phase liquids (LNAPL or gasoline), if present, using an interface probe. During the period, measurable LNAPL was not detected in the gauged monitoring wells. The depth to water in the release area ranged from approximately 17,73 feet in well MW- 101 to 18.75 feet below the lip of the PVC in well MW-C. These depths are higher than the depths gauged during the December 21, 2022 gauging event. Please refer to Table I for a summary of well gauging data. The wellhead elevations and well gauging data from March 27, 2023 were coupled to determine the hydraulic gradient. As can be seen from Figure 4 the hydraulic gradient is down to the south. The selected well, MW-1, was then assessed for Monitored Natural Attenuation (MNA), by lowering a piece of clean low density polyethylene (LDPE) tubing into the well until the intake was set at approximately the middle section of the submerged well screen. A peristaltic pump was connected to the LDPE tubing, using new silicon tubing, to extract water from the well. The water was pumped from the well into a flow -through cell. A calibrated YSI Pro Quatro was sealed in the flow -through cell and was used to monitor the groundwater quality during pumping so that stabilization could be identified. Groundwater quality monitoring was performed on monitoring well MW-1, and included pH, temperature, specific conductance, dissolved oxygen, and oxidation reduction potential. Water was extracted from the well at a pumping rate of approximately 180 ml/minute. The Monitored Natural Attenuation (MNA) results, for MW-1, after stabilization, are summarized as follows: • pH was 6.06 standard units; • Temperature was 12.7 degrees Celsius; • Specific conductance was 0.271 milliSiemens per centimeter; • Dissolved oxygen (optical) 1.00 milligrams per liter; and • Oxygen reduction potential was -17.5 millivolts. Please see Table 3 for a summary of the MNA data. A sample was collected from the well by pumping water from the tubing, prior to the flow through cell, into clean, laboratory provided, pre -preserved 40 ml VOA vials. The sample was chilled on ice and transported under chain -of -custody to Alpha Analytical, Inc. The sample was submitted for analysis extractable petroleum hydrocarbons(EPH), Volatile Petroleum Hydrocarbons (VPH) and associated target analytes.

Target analytes were not detected at concentrations at or above the applicable Method 1 Risk Characterization standards. These results are similar to the results from the September 2022 sampling event. Analysis of the sample collected from well MW-1 for EPH detected only C11-12 aromatic hydrocarbons at a concentration above the applicable Method 1 Risk Characterization standard. The results are similar to the results from the December 2022 sampling event. Refer to the attached graph for EPH and VPH changes over time. Please refer to Table 2 for a summary of groundwater analytical results and Appendix A for a copy of the laboratory analytical report. 3.3 Remediation Discussion In January, 2006, a Phase IV Remedy Implementation Plan was submitted to the MassDEP. The RIP called for In -Situ bioremediation and groundwater monitoring. Groundwater from monitoring wells MW-1, MW-2 and MW-301 had concentrations of hydrocarbons that exceeded the applicable standards. Therefore, microbes and a nutrient mix were injected into monitoring wells MW-1, MW-2 and MW-301. The mixture contained 8-12 strains of hydrocarbon degraders that reportedly work in both aerobic (oxygen) and anaerobic (non - oxidized) environments. The liquid nutrient mixture contained phosphates, potassium and nitrogen compounds. The mixture was last injected in September of 2011. The hydrocarbons in samples collected from wells MW-2 and MW-301 had decreased to concentrations below the applicable standards by 2015. Since 2015, Edge has been performing groundwater monitoring using the parameters associated with monitored natural attenuation (MNA). MNA is also a remedial method that relies on dispersion, advection, dilution, sorption, volatilization and natural biodegradation. Natural biodegradation is the principal mechanism for attenuation of petroleum hydrocarbons in soil and groundwater. MNA is effective in reducing petroleum hydrocarbons to varying degrees depending on the types and concentrations of petroleum constituents present and the physical, chemical, and biological characteristics of the soil and groundwater. Favorable conditions for MNA will reduce petroleum concentrations over time to achieve remedial objectives and reduce potential risks. The residual petroleum hydrocarbon concentrations in groundwater samples from well MW-1 continue to have a four -quarter average above the applicable Method I GW-I groundwater standards. The residual petroleum hydrocarbon concentrations do have decreasing trends as shown in the attached graph. The groundwater elevation and analytical data for well MW-1 has been graphed to present the change in petroleum hydrocarbons over time. Two characteristics can be discerned from the attached graph. The first is that elevation of groundwater does not fluctuate more than approximately three feet. The second characteristic is that the concentrations in samples are decreasing over time. Therefore, either MNA and/or the hydrocarbon degraders are slowly reducing the residual gasoline -related compounds. Due to the slowness of this process, Savon Gas requested a review of groundwater data and a determination of whether it would be cost effective to reintroduce one or more amendments to speed up the remedial process. Therefore, during the June 2019 round of groundwater sampling and analysis, Edge submitted samples collected from wells MW-I, ECS-2 and ECS-3 for general chemistry analyses. These analyses included pH, nitrogen as nitrate, total phosphorus, sulfate, chemical oxygen demand (COD), 5-day bio-chemical oxygen demand (BOD) and ferrous iron. Oxygen, nitrate, manganese, iron, and sulfate are terminal electron acceptors that must be present for bacteria to consume petroleum. The wells selected for the analyses were chosen based on their locations relative to the plume. Well ECS-2 (not impacted) is located hydraulically upgradient from well MW-1. Monitoring well ECS-3 is considered hydraulically crossgradient from MW-1. Monitoring well MW-1 is believed to be in the plume.

Yarmouth MA 02664 File No. 2015.09 A discussion of the results from the MNA monitoring and the general chemistry of water analyses results from wells MW-1, ECS-2 and ECS-3, collected on June 25, 2019, and from September 2022 follow: • The pH of the water in the three wells is similar, ranging from 5.87 in well ECS-2 to 6.17 in ECS-3. There is little difference in these results and these pH values are within the normal range for this Site. • The specific conductance for samples from ECS-2 and ECS-3 were 0.186 mS/cm and 0.233 mS/cm as opposed to the 0.436 mS/cm from MW-1. Specific conductance is a measure of the ability of an aqueous solution to conduct an electric current. Changes (usually increases) in conductivity may indicate that a discharge (e.g. petroleum) or some other source of disturbance has decreased the relative condition or health of the water body. The specific conductance for samples did not vary significantly. A decreasing trend is evident in the water samples from well MW-1. See Table 3. • The dissolved oxygen (DO) in samples from wells ECS-2 and ECS-3 were 9.00 mg/L and 7.64 mg1L, respectively. These measurements indicated that oxygen is present in the groundwater upgradient and crossgradient of the plume. The DO in the samples from MW-1 appear to have an increasing trend. The fact that the DO in water from MW-I has increased from 0.84 mg/L (March 2019) to 1.0 mg/L (march 27, 2023) may indicate that this portion of the plume has changed and become more aerobic. • The oxidation reduction potential (ORP) in samples from wells ECS-2 and ECS-3 were 140.4 millivolts (mV) and 97.8 mV, respectively. The ORP in the sample from MW-I in September 2022 was 69 mV and was -17.5 mV. In groundwater, the ORP is the tendency of the water to either gain or lose electrons. A positive ORP represents an environment conducive to the oxidation of a substance (petroleum). The positive ORP readings in wells ECS-2 and ECS-3 indicates that the groundwater outside the plume has the potential to oxidize the petroleum. The reading from well MW-1, -17.5 mV, appears to indicate that petroleum is being oxidized. • The nitrogen concentrations, as nitrate (NO3), ranged from 2,62 mg/L to 2.90 mg/L in groundwater samples. Nitrate generally ranges from 0.1 mg/L to 10 mg/L in groundwater (Groundwater and Wells, Johnson Filtration System Inc., 1986). Nitrate is generally depleted within a plume. These similar concentrations appear to indicate that nitrate is not readily available in the groundwater. • Total Phosphorus (total) is required for all life forms. Phosphorus supports the growth and development of microbes. Phosphorus concentrations ranged from 0.017 to 0.103 mg/L. • Sulfate concentrations (SO4) ranged from 16 to 20 mg/L. Sulfate is used by bacteria and transformed to sulfite and sulfides. Sulfates were somewhat depleted in the samples from three wells. • The concentrations of ferrous iron and manganese will be depleted by microbial activity. The fact that ferrous iron was not detected in the samples and the concentrations of manganese were low appear to indicate that the bacteria are using them to process petroleum and may be somewhat depleted. • Potassium uptake is essential for all living organisms. The water samples from the three wells had potassium ranging from 3.55 mg/L to 8.49 mg/L. The concentration of potassium increased from 3.55 mg/L upgradient from the plume to 8.49 mg/L in the plume. This is an unexpected result. • The chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that is available or can be consumed by reactions in groundwater. The CODS in water from the three wells was less than the detection limits of the method. • The biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria during the decomposition of organic matter (petroleum) under aerobic conditions (oxygen is present). The BODs in water from all three wells is less than the detection limits of the method and indicated that there was little oxygen available. Based on the prior presented information, there are relatively low concentrations of hydrocarbons in groundwater on -site. The concentrations of oxygen, sulfate and iron appear to be depleted. Due to the depletion, the conditions in the groundwater may be anaerobic. The addition of amendments could be used to PO Box 5262 1 Manchester, NH 03108 1 Phone: 603-717-8908 Edge Environmental, LLC Consulting and Engineering www.Edp-eEnviroLLC.com RTN 4-17422 Phase V Status & RMR Dec. 2022 — May 2023 Page 6 Mr. Jay ]mad Jay Mart June 14, 2023 Gasoline Release 1282 Main Street, So.

Please see Table 4 for a summary of the Groundwater Quality data. 4.0 PHASE V SUMMARY AND RECOMMENDATIONS Edge concludes the following based on data collected this period: • Groundwater samples were collected from monitoring well MW-1 in December 2022 and March 2023. Analysis of the samples collected from monitoring well MW-1 detected gasoline constituents at concentrations above the Method 1 Risk Characterization standards. These results appear to reflect seasonal fluctuations. The concentrations in samples show a decreasing trend over time. Therefore, either MNA and/or the hydrocarbon degraders are slowly reducing the residual concentrations of gasoline -related compounds. • This Phase V Status Report was prepared in accordance with the requirements specified in the MCP. Comprehensive Response Actions will continue under Phase V. Based on the data presented in this Phase V Status Report, it is the opinion of the LSP of record that MNA has been implemented in accordance with Section 310 CMR 40,0870 of the MCP and the Operation, Maintenance and Monitoring Plan. The monitoring program will continue under Phase V until a Permanent Solution is achieved. Edge recommends the following: • The continued collection and analysis of groundwater samples during the months of June and November 2023. This will provide analytical data that can be used to monitor whether the downward trend continues. Samples will be collected using a modified version of the low stress low flow method. 5.0 REPORTING The next Phase V Status and Remedial Monitoring Report is due in December 2023. 6.0 LIMITATIONS AND CONDITIONS The Licensed Site Professional Opinion, Section E of BWSC-105, and this report, which is an integral part of the opinion, are subject to the Limitations and Conditions presented as Appendix D.

Please refer to the Sample Results and Container Information sections of this report for specification of MCP methods used for each analysis. The following questions pertain only to MCP Analytical Methods. An affirmative response to questions A through F is required for "Presumptive Certainty" status A Were all samples received in a condition consistent with those described on the Chain -of- YES Custody, properly preserved (including temperature) in the field or laboratory, and prepared/analyzed within method holding times? B Were the analytical method(s) and all associated QC requirements specified in the selected YES CAM protocol(s) followed? C Were all required corrective actions and analytical response actions specified in the selected YES CAM rotocol s implemented for all identified performance standard non -conformances? D Does the laboratory report comply with all the reporting requirements specified in CAM Vll A, YES "Quality Assurance and Quality Control Guidelines for the Acquisition and Reporting of Analytical Data?" E a. VPH, EPH, and APH Methods only: Was each method conducted without significant YES modifications ? Refer to the individual methods for a list of significant modifications). E b. APH and TO-15 Methods only: Was the complete analyte list reported for each method? NIA F Were all applicable CAM protocol QC and performance standard non -conformances identified YES and evaluated in a laboratory narrative (including all "No" responses to Questions A through E A response to questions G, H and I is required for "Presumptive Certainty" status G Were the reporting limits at or below all CAM reporting limits specified in the selected CAM NO protocol(s)? H Were all QC performance standards specified in the CAM protocol(s) achieved? YES I Were results reported for the complete analyte list specified in the selected CAM protocol(s)? YES For any questions answered "No", please refer to the case narrative section on the following page(s). Please note that sample matrix information is located in the Sample Results section of this report. LPHA Page 3 of 24 Project Name: JAY MART Project Number: 2015.09 Case Narrative Serial No:01062316:4O Lab Number: L22718O6 Report Date: 01/06/23 The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report. Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter (i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List, even if only a subset of the TCL are being reported. If a sample was re -analyzed or re -extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re -analysis or re -extraction is designated with an "R" or "RE", respectively. When multiple Batch Quality Control elements are reported (e.g, more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. in these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. OC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications. Soilisediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located al the back of the report. HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed. Please contact Project Management at 800-624-9220 with any questions.
