These two properties are part of the larger Massachusetts Department of Environmental Protection (MassDEP) Disposal Site assigned Release Tracking Number (RTN) 3-38273 (the “Site”). The Site includes portions of the properties at 14 Barnes, 9 Cedar Road, 12 Cedar Road, 14 Cedar Road, 15 Cedar Road, and 16 Cedar Road. The IHE was completed as part of the Immediate Response Action (Plan) submitted by Blackstone Environmental Solutions LLC (BES) to MassDEP in October 2023. The Site information provided in the IRA and the subsequent soil data provided by BES for 14 and 16 Barnes Road were used in the IHE. The IHE was completed in accordance with MassDEP regulations under the Massachusetts Contingency Plan (MCP: 310 CMR 40.0950) and applicable MassDEP guidance. On August 11, 2023, MassDEP was notified on behalf of Barnes Road Trust that the vacant property located at 14 Barnes Road has triggered a MCP 2-hour reporting condition potential Imminent Hazard Condition). The 14 Barnes Road property is located immediately adjacent to 14 Cedar Road. The dataset generated as part of an assessment by Weston & Sampson on October 9, 2020, includes a total biphenyls (PCB) concentration of 118.3 mg/kg that was collected in the top 6 inches of material at location N-9. This PCB concentration is above the notification threshold for the purpose of fulfilling the “Two Hour” release notification obligations of 310 CMR 30.0311(7), as a “Could Pose” Imminent Hazard to human health. MassDEP verbally approved environmental response actions to be conducted under RTN 3-38273 for 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, and includes but not limited to an expedited subsurface investigation program to address the potential Imminent Hazard condition to human health at the Site. The assessment activities will be performed to further investigate the source of the shallow heavy metals, including chromium and lead, and PCB impacted soils. Also, MassDEP has approved the installation of a security fence along the southern boundary of 16 Barnes Road in order to restrict access to 14 Barnes Road via a trespasser scenario. On August 28, 2023, a Site inspection was conducted with representatives of MassDEP, Ash Desmond (Bureau of Waste Site Cleanup BWSC][) and Andrew Danikas (asbestos inspector), and Michael Bricher, LSP, of BES. The inspection consisted of a of 14 Barnes, 16 Barnes Road, 9 Cedar Road, 12 Cedar Road, and 15 Cedar Road. Due to the dense forest land, poison ivy/oak vegetation, thorns, ticks, wetlands, and terrain physical barriers), access was limited at each of the aforementioned properties. A summary of Site observations for 14 and 16 Barnes Road is noted below. ---PAGE BREAK--- Imminent Hazard Evaluation 14 and 16 Barnes Road Salem, MA October 2023 5210-11-01 2 16 Barnes Road: This property was accessed from the south along Barnes Road. MassDEP and BES reviewed the area along the southern property boundary for the installation of a potential fence installation. We agreed that there would need to be a significant amount of tree/vegetation removal and to go around a bedrock outcrop to complete the fence installation along the southern property boundary line. It was also noted that a significant elevation drop at approximately 100 feet from the road going straight in towards 14/16 Barnes Road property boundary and that it would be unsafe to access 14 Barnes Road from the southwest. Also, we noted multiple construction/ demolition/solid waste debris brick, asphalt, concrete/tires/metal, broken tiles) along the property boundary for 14 and 16 Barnes Road. Asbestos Inspector Danikas collected two samples of the tile and roofing material for asbestos. It was later confirmed by MassDEP that the tile sample tested positive for asbestos. According to the property owner, Kathleen Ingemi for JMI Realty Trust, this area of 16 Barnes Road has been subject to illegal dumping activities over the years by nearby owners. Nonetheless, this area of the Site will need to be assessed by a licensed asbestos inspector/management company. 14 Barnes Road: MassDEP and BES accessed 14 Barnes Road from the west via 379-381 Highland Avenue. Access was limited to the westernmost portion of 14 Barnes Road due to physical barriers. There was some solid waste debris (tires, metal, brick, concrete, abandoned storage shed) observed in this area, but MassDEP asbestos inspector did not identify any potential asbestos containing material at the surface. Containment Measure Actions: At the time of release notification for 14 Barnes Road, BES presented a verbal IRA Plan to MassDEP to erect a 6-foot-high chain-link security fence along the southern boundary of 16 Barnes Road to restrict access to the heavy metal and PCB impacted surficial soil areas reported at the Site. Based on the MassDEP/BES Site Visit on August 28, 2023, there are logistical challenges physical barriers) with installing a security fence along the southern boundary of 16 Barnes Road. Based on feedback received by BES from Mr. Erik Johnson of MassDEP BWSC on August 30, 2023, MassDEP would consider using the existing physical barriers on 16 Barnes Road in lieu of a security fence if surficial soil data shows that the heavy metals and PCBs are below Imminent Hazard levels. Following the completion of the upcoming IH Evaluation for potential trespasser exposure via dermal contact to soil at 14 and 16 Barnes Road, the need to supplement the existing physical barriers with additional containment measures will be assessed. 2.0 SURFICIAL SOIL SAMPLING On September 27, 2023, BES personnel conducted a surficial soil assessment program on 14 and 16 Barnes Road. The assessment program area was divided into 5 zones for surficial soil sampling. These five sampling zones were identified as SS- 31, SS-32, SS-33, SS-34, and SS-35. The sampling zones were strategically selected to represent areas that would most easily be accessed in a trespasser scenario from ---PAGE BREAK--- Imminent Hazard Evaluation 14 and 16 Barnes Road Salem, MA October 2023 5210-11-01 3 Barnes Road. Approximately 330 feet of street frontage exists along the southern boundary for 16 Barnes Road. Refer to IRA Plan Figure 2-Soil Sample Location Map for a depiction of the five sampling zones. As previously noted, this area of the Site consists of thick wooded vegetation with exposed bedrock outcroppings. Also, multiple construction/demolition/solid waste debris material brick, asphalt, concrete/tires/metal, broken tiles) was observed during this assessment program. The soil samples were collected at a depth of 0 to 1’ below grade using a hand auger. The soil samples comprised mostly of organics with some silts, sands, and gravel. There were no overt petroleum odors, soil staining, or visual evidence of release of oil and/or hazardous material at these locations. Also, soil samples were field screened for total volatile organic compounds (TVOCs) with a photoionization detector (PID) equipped with a 10.6 eV lamp and calibrated to 100 ppmv isobutylene utilizing the MassDEP approved “Jar Headspace Analytical Screening Procedure”. The PID screening reading results for all soil samples were non-detect (0.0 parts per million (ppm). A total of five soil samples SS-31 through SS-35) were collected and submitted to New England Testing Laboratory (NET Lab) of West Warwick, RI under standard chain of custody (COC) procedures for the following analyses: MCP 14 Metals by EPA Method 6000/7000; and biphenyls (PCBs) by EPA Method 8082A. In addition, soil sample SS-32 as submitted for SVOC laboratory analysis via EPA Method 8270. These soil sample laboratory analytical results will be presented in the IRA Status Report anticipated for MassDEP submittal on or before December 5, 2023. The analytical results for detected analytes are presented in Table 1. It is noted on this table that PCBs were not detected at analytical detection limits less than 86 ug/kg. Metals were detected in each sample. SVOCs, primarily aromatic hydrocarbons (PAHs), were detected in the one sample (SS-3) analyzed for this group of compounds. It is also noted that the maximum concentration of arsenic, cadmium, and mercury are below MassDEP’s Background Concentrations in “Natural” Soil (MassDEP, 2002). These three metals are not considered to be constituents of concern for this IHE. 2.0 SITE-SPECIFIC IMMINENT HAZARD EVALUATION FOR HUMAN HEALTH The Site-specific exposures considered in this IHE (310 CMR 40.0953) are as follows. The short period of time considered in the evaluation was five years. For the evaluation of soil-related exposures, the level of OHM starting at zero to twelve inches within the ground surface were used in the development of Exposure EPCs. No hot spots were not identified for the subject portions of the Site. The IHE was focused on the detected metals (exceeding MassDEP Background Concentrations for “Natural” Soil [MassDEP, 2002]), and SVOCs as constituents of concern. Maximum detected concentrations were used as EPCs. ---PAGE BREAK--- Imminent Hazard Evaluation 14 and 16 Barnes Road Salem, MA October 2023 5210-11-01 4 The IHE was conducted in a manner, which results in conservative estimates of potential exposures. The IHE clearly identifies and explains the basis for exposure parameters chosen for the Risk Characterization. The characterization of the risk of harm to human health was conducted using a Method 3 approach, as described in 310 CMR 40.0993. The toxicity information used to characterize risk is consistent with the type and duration of exposure under evaluation, and primary consideration given to information developed by MassDEP (310 CMR 40.0955(2)(a)). 2.1 IMMINENT HAZARD EVALUATION FOR TRESPASSERS The properties at 14 and 16 Barnes Road are currently undeveloped. However, the closest occupied residential building is less than 500 feet away. Therefore, members of the general public could trespass on these properties in the absence of barriers. Therefore, the IHE for human health was evaluated for a trespasser that would occasionally access the properties. Direct contact risks to soil by trespassers were calculated using the MassDEP Method 3 Imminent Hazard Assessment for Trespasser Exposed to Chemicals in Soil - Shortform 2012 (sf12tsih) (Vlookup Version 0315). (Attachment The default exposure assumptions in this Shortform for subchronic noncancer effects assumes the receptor is a 11 to 12 year old, soil ingestion rate of 50 mg/day, exposure frequency of 2 days/week for 30 weeks (60 days/year), and exposure period of 1 year for noncancer subchronic effects (Table TSIH-4, Sheet: Exp). The equations to calculate noncancer risk for a trespasser are presented in Table TSIH-3, Sheet: NC Eq. For carcinogenic effects, the receptor is a 11 to 16 year old, soil ingestion rate of 50 mg/day, exposure frequency of 2 days/week for 30 weeks (60 days/year), and exposure period of 5 years over a 70 year lifetime (Table TSIH-4, Sheet: Exp). The equations to calculate cancer risk for a trespasser are presented in Table TSIH-2, Sheet: C Eq. Exposure point concentrations (EPCs) were selected from the five samples (SS-31 to SS-35) as the maximum detected concentrations of detected analytes (Table These EPCs were input into the Shortform (Table TSIH-2, Sheet: EPCs). The toxicity values for COCs are encoded in the Shortform (Table TSIH-5; Sheet: Chem). It is noted that chromium was evaluated in the trivalent form. Hexavalent chromium was not detected in the sediments in the Mill Pond, nor in other soil, lagoon, and sediment samples collected for the ADW Disposal Site. Subchronic noncarcinogenic risks were calculated as the Hazard Index (HI). Cancer risks were calculated as the Excess Lifetime Cancer Risk (ELCR) (Table TSIH-2, Sheet: EPCs). ---PAGE BREAK--- Imminent Hazard Evaluation 14 and 16 Barnes Road Salem, MA October 2023 5210-11-01 5 The total IH noncancer risk HI from soil exposure by trespassers is 0.08. This value is well below the MassDEP IH noncancer risk limit for HI of 10, with the Hazard Quotient for lead being less than 1. The total IH cancer risk ELCR from soil exposure by trespassers is 8E-07. This value is well below the MassDEP IH cancer risk ELCR of 1E-05. Therefore, a condition of No Imminent Hazard was concluded for trespassers. 3.0 SITE-SPECIFIC IMMINENT HAZARD EVALUATION FOR SAFETY In accordance with Section 310 CMR 40.0960 of MCP, the Site was also evaluated for the risk of harm to safety associated with current and reasonably foreseeable conditions at the site. In general, this evaluation considers acute hazards such as fire and explosion, the potential for exposure to acute concentrations that might be immediately threatening to life or health, and the potential for chronic exposure levels to the general public that might result from ongoing uncontrolled releases. According to the MCP, the following Site conditions indicate a condition of No Significant Risk of harm to safety exists at the site: No applicable or suitably analogous safety standards were identified for the site (310 CMR 40.0960(2)); therefore, there were no exceedances of these standards. No rusted or corroded drums or containers, open pits, lagoons, or other dangerous structures were observed on the site (310 CMR 40.0960(3)(a)). There is no present threat of fire or explosion, including the presence of explosive vapors resulting from a release of OHM (310 CMR 40.0960(3)(b)). No uncontained material which exhibit the characteristics of corrosivity, reactivity or flammability exists at the site (310 CMR 40.0960(3)(c)). Therefore, a condition of No Imminent Hazard exists for Safety. 4.0 SITE-SPECIFIC IMMINENT HAZARD EVALUATION FOR THE ENVIRONMENT An IH to the environment would exist with evidence of stressed biota or immediate or acute adverse impacts to freshwater or saltwater fish populations. These conditions do not exist. Therefore, a condition of No Imminent Hazard to the environment was concluded. 5.0 CONCLUSIONS A condition of No Imminent Hazard exists for human health, safety, and the environment exists for the surficial soil at 14 Barnes Road and 16 Barnes Road properties at the Site. ---PAGE BREAK--- Imminent Hazard Evaluation 14 and 16 Barnes Road Salem, MA October 2023 5210-11-01 6 REFERENCES Massachusetts Department of Environmental Protection (MassDEP). 1995.

This is the concentration of available cyanide in soil below which acute human health effects would not be expected following a one-time exposure. This soil concentration is calculated using the equation below with a one-time soil ingestion estimate of 50 mgsoil and an available cyanide dose limit of 0.01 mg/kgbody weight. MassDEP’s guidance on evaluating the risk from a one-time cyanide dose considers cyanide’s potentially lethal effects as well as information on cyanide metabolism: Cyanides are detoxified rapidly by the body, and a large acute dose which overwhelms the detoxification mechanism is potentially more toxic than the same dose distributed over a period of hours. (MassDEP Background Documentation for the Development of an Available Cyanide Benchmark Concentration, originally dated October 1992, Modified August 1998) Assessment of a potential one-time dose requires an estimate of the maximum soil concentration the trespasser could contact at any one time. The average soil concentration within a typical exposure area will underestimate the potential one-time dose. Therefore, to assess the acute risk of a one-time potentially lethal dose, the EPC for cyanide should be a conservative estimate of the maximum soil concentration.
