After subsurface assessment, this report concludes there is No Imminent Hazard (IH) for the below-referenced conditions evaluated at portions of 12 Cedar Road, 14 Cedar Road and 14 Barnes Road located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road. A detailed summary of the response action activities resulting in this conclusion are described herein These properties are part of the larger Disposal Site associated with parent RTN 3-38210, and also include portions of the properties at 9 Cedar Road, 15 Cedar Road, 16 Cedar Road, and 16 Barnes Road (the “Site”). A Site Locus, Site Plan, Aerial Map MassDEP Phase I Site Assessment Map are included as Figures 1, 2, 3, and 4, respectively. Those areas identified as potentially hosting Imminent Hazard conditions were assessed. A “Could Pose” Imminent Hazard reporting condition was determined to have existed on 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, as a result of the reported presence of biphenyl (PCB) and total chromium impact in the top 12 inches of soil. The dataset used in the IH regulatory notification process included an assessment by Weston & Sampson of Reading MA on October 9, 2020. The Weston and Sampson Report identified dumped shredded automobile parts [automobile shredding residue (ASR)] within the investigation area, and attributed this material as both historic in nature, most likely from over fifty (50) years ago, and as the source of the hazardous materials in soil, including PCBs and heavy metals. A summary of these assessment activities is presented in the Weston & Sampson- Summary of Work Memorandum dated November 17, 2020, and is included in Appendix A. This IRA Status Report details the assessment activities performed at the Site to determine the source, nature and extent of the release associated with the “could pose” Imminent Hazard reporting condition and to assure the continued absence of any critical exposure pathway (CEP) or a condition of substantial release migration (SRM) from occurring at the Site. Response actions covered by this report are from October 4 through November 30, 2023. The parties currently assuming responsibility for conducting this IRA is the “Trusts”, although another party, Prolerized New England Company, LLC (PNE) has been sent a Notice of Responsibility by MassDEP.

A summary of the response activities is described in the following sections. ---PAGE BREAK--- IRA Status Report # 1 and IHE (RTN 3-38273) Page 3 of 9 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, MA December 2023 Blackstone Environmental Solutions, LLC 76 Bay View Drive Shrewsbury MA 01545 (508) 612-4738 ꞏ www.bes-env.com 2.1 Imminent Hazard Evaluation Results-330 Foot Street Frontage at 14 and 16 Barnes Road On behalf of the Trusts, BES filed an IHE Results with MassDEP on October 18, 2023 for a portion of 14 and 16 Barnes Road. The IHE was performed to evaluate the risks associated the potential trespasser exposure pathway via dermal contact to soil at a portion of 14 Barnes Road and 16 Barnes Road. The laboratory soil sampling activities was performed at the aforementioned properties on September 27, 2023. The IHE Results concluded that a condition of No Imminent Hazard exists for human health, safety, and the environment for portions of 14 Barnes Road and 16 Barnes Road in Salem, Massachusetts located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road. Also, it was noted that the IHE will be reevaluated if conditions are identified in the future which are materially different from those characterized to date. An IHE Results Amendment was filed with MassDEP on October 20, 2023. Based on feedback received from MassDEP staff on the October 18, 2023 IHE Results submittal, BES filed the Amendment in order to provide more clarity on the specific areas where the risk assessment conclusions were made approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road). 2.2 Cedar Road Easement Access Status In an attempt to perform environmental soil sampling activities at the vacant parcels located at 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, BES and the Trusts’ legal representation reached out to representatives of Berman Properties LLC (Berman) to secure access to the Cedar Road Easement on several occasions during the period of mid-September, 2023 through November 7, 2023. The Cedar Road Easement was viewed to be the safest route to access these vacant parcels because it would not require crossing a large area of wetlands, swamps, dense vegetative growth or steep/rocky terrain. Due to the fact that the Berman redevelopment project at Highland Avenue and Cedar Road 355-373 Highland Avenue) is an asbestos cleanup site, a thorough decontamination written program was prepared by BES and approved by the MassDEP Bureau of Air and Waste Division. Ultimately, property access was denied to the Cedar Road Easement from Highland Avenue by Berman representatives for the planned November 13 and 14, 2023 surficial soil sampling activities due to business interference concerns during the on-going construction activities. It is BES and the Trusts informed expectation that an access agreement can be secured to the Cedar Road Easement via Highland Avenue with Berman representatives upon completion of the site-related construction activities. Given the fact that access was denied to the Cedar Road Easement via Highland Avenue, BES ---PAGE BREAK--- IRA Status Report # 1 and IHE (RTN 3-38273) Page 4 of 9 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, MA December 2023 Blackstone Environmental Solutions, LLC 76 Bay View Drive Shrewsbury MA 01545 (508) 612-4738 ꞏ www.bes-env.com performed a job safety analysis on November 9, 2023 for accessing the Cedar Road properties via Barnes Road. Although not ideal for carrying sampling equipment through 300+ feet of thick wooded vegetation with the downward sloped/rocky terrain, the safety risk was viewed to be manageable during this time of year better visibility with no leaves on trees, no concerns of poison ivy/oak or flies/bugs/insects) while having other field staff on Site working as a collective team. Accordingly, the November 13 and 14, 2023 surficial soil sampling plan was modified in order to access the IH investigation areas via Barnes Road. 2.3 Surficial Soil Sampling Activities-November 13 and 14, 2023 Surficial soil sampling activities were completed by BES as part of the IRA assessment program to determine the horizontal extent of PCB and heavy metal contamination at the Site in conformance with the MCP and federal Toxic Substance Control Act (TSCA) requirements. The comprehensive soil sampling program was performed within and around five sampling areas Cedar Road Easement, 12 Cedar Road, 14 Cedar Road, 16 Cedar Road, and 14 Barnes Road). In addition, the data collected from this surficial soil sampling program will be used to aid in developing a supplemental assessment program to determine the full extent of contaminants of concern (COC) impacted soil at the Site, and the implementation of a groundwater assessment program. During assessment activities performed at the Site, standard protocols/procedures were performed in general conformance with BES SOPs, general industry standards and appropriate MassDEP and/or EPA Policies and/or Guidance. All soil samples collected for laboratory analyses were transported to New England Testing Laboratories of West Warwick, RI under standard Chain of Custody documentation procedures. The soil samples were analyzed for the following parameters:  PCBs by EPA Method 8082A;  MCP 14 Metals; and  SVOCs via EPA Method 8270 (select samples only). Surficial soil sampling laboratory results are summarized on Tables 1A and 1B. Soil laboratory analytical reports are provided in Appendix B. A total of thirty surficial soil samples (identified as SS-1 through SS-30) were collected across the aforementioned sampling areas on November 13 and 14, 2023. Refer to Figure 2-Site Plan for a depiction of the surficial soil sampling locations. Labelled wood stakes were installed at each sample location and will be surveyed for elevation and location at a later date. All soil samples were collected with a hand auger from a depth of 0 to 1 foot below grade. The soil samples comprised mostly of organics with some silts, sands, and gravel. 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 ---PAGE BREAK--- IRA Status Report # 1 and IHE (RTN 3-38273) Page 5 of 9 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, MA December 2023 Blackstone Environmental Solutions, LLC 76 Bay View Drive Shrewsbury MA 01545 (508) 612-4738 ꞏ www.bes-env.com the MassDEP approved “Jar Headspace Analytical Screening Procedure”.

An IHE was performed to evaluate the risks associated the potential trespasser exposure pathway via dermal contact associated with PCBs, total chromium, as well as other heavy metals and semi-volatile organic compounds detected in the surficial material at 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road. The IHE was performed by O’Reilly Talbot & Okun Associates of Westborough, MA (OTO), and is presented in Appendix C. The conclusion from the IHE Report is provided below: “A condition of No Imminent Hazard exists for human health, safety, and the environment exists for the portions of 12 Cedar Road, 14 Cedar Road and 14 Barnes Road in Salem, Massachusetts located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road.” The Site will continue to be assessed and monitored for potential Imminent Hazards. 2.5 Asbestos Assessment On behalf of the Trusts, Axiom Partners, Inc., of Lynfield, MA (AXIOM) performed bulk sampling of suspect asbestos-containing materials (ACM) and collected surficial soil samples adjacent to locations of suspect ACM on November 13 and 14, 2023. The suspect ACM and soil samples were collected by David Rooney of AXIOM, a Massachusetts-licensed Asbestos Inspector (License #AI 061851). The asbestos assessment areas included portions of 14 Barnes Road, 16 Barnes Road, 12 Cedar Road, 14 Cedar Road, and 16 Cedar Road. An Asbestos Testing Summary Report will be prepared by Axiom and filed with MassDEP under a separate cover, anticipated for submittal on or before December 15, 2023. There was no evidence of friable asbestos located at or on the surface of the areas inspected. 3.0 MANAGEMENT OF IRA GENERATED WASTE No remediation waste was generated for this IRA during the monitoring period. ---PAGE BREAK--- IRA Status Report # 1 and IHE (RTN 3-38273) Page 8 of 9 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, MA December 2023 Blackstone Environmental Solutions, LLC 76 Bay View Drive Shrewsbury MA 01545 (508) 612-4738 ꞏ www.bes-env.com 4.0 SIGNIFICANT NEW SITE INFORMATION OR DATA On October 25, 2023, MassDEP issued a Notice of Responsibility to Prolerized New England, LLC for the same RTNs issued to the Trusts 3-38273 & 3-38210). Specifically, the NOR states the following: “12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, Massachusetts (collectively, the Site) were the location of the disposal of automotive shredder residue (ASR). MassDEP files contain information indicating that ASR, dumped at the Site in or about the 1970s, was from PNC. Through environmental testing, ASR has been identified in several areas across the Site at ground level and to depths of up to 35 feet below grade.” Legal representatives from the Trusts and PNE are currently in discussions to secure a cost allocation agreement for completing the required environmental response actions at the Site in accordance with MassDEP/EPA regulations. 5.0 SUMMARY AND CONCLUSIONS This IRA is being conducted at the Site as a result of a “2-Hour” notification condition associated with the presence of PCBs and total chromium within 12-inches of the ground surface at a location within 500 feet of a residential property, and at a concentrations greater than 10 mg/kg and 200 mg/kg, respectively. The “2-Hour” notification condition was based on surficial soil laboratory analytical results collected by others in 2020 at the vacant parcels of land located at 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road. Since the initial IRA notification was made for the Site under RTN 3-38273 on August 7, 2023, BES and the Trusts legal representatives have been coordinating and regularly communicating with MassDEP staff in the performance of the critical and timely IRA assessment efforts described herein. Based on the assessment activities performed to date at the Site, it is the opinion of BES that the source of the PCBs and heavy metals, including chromium and lead detected in the shallow soil samples is attributed to the historic fifty (50) year old dumping/landfilling of ASR material observed throughout the Disposal Site. This opinion is supported by the fact elevated concentrations of PCBs and heavy metals in surficial soil were observed in the immediate vicinity of the ASR material. The ASR material consisted of metal, rubber, plastic, foam, glass, and wire. Records obtained by MassDEP indicate that the ASR material was dumped at the Site in or about the 1970’s by PNC. Access to the ASR material and shallow PCB/heavy metal-impacted soils at the Disposal Site is limited by a combination of factors, including fencing, wetlands, swamps, dense vegetative growth, and steep/rocky terrain. No evidence of any recent land disturbance/trespassing to the Disposal Site was observed. ---PAGE BREAK--- IRA Status Report # 1 and IHE (RTN 3-38273) Page 9 of 9 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road, Salem, MA December 2023 Blackstone Environmental Solutions, LLC 76 Bay View Drive Shrewsbury MA 01545 (508) 612-4738 ꞏ www.bes-env.com An IHE was performed to evaluate the risks associated the potential trespasser exposure pathway via dermal contact associated with PCBs, total chromium, as well as other heavy metals and semi-volatile organic compounds that were detected in the surficial material at 12 Cedar Road, 14 Cedar Road, and 14 Barnes Road. The conclusion from the IHE is that there is no Imminent Hazard for human health, safety, and the environment exists for the portions of 12 Cedar Road, 14 Cedar Road and 14 Barnes Road in Salem, Massachusetts located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road. The Site will continue to be assessed and monitored for potential Imminent Hazards. Future response actions will be performed in accordance with the October 6, 2023 IRA Plan and MassDEP approvals, as needed. 6.0 ANTICIPATED SCHEDULE OF IRA ACTIVITIES Additional assessment is planned to be conducted to further delineate PCBs, metals and other contaminants identified at the Disposal Site, and to continue to evaluate for IH, CEP, and SRM conditions. As previously noted, the Trusts and PNE are currently in discussions regarding the proposed next steps for advancing the Site through the MCP process. In addition, both parties will need to reach a cost allocation agreement before additional environmental response actions are performed at the Site. The next IRA submittal will be filed with the MassDEP on or before June 5, 2024. 7.0 PUBLIC INVOLVEMENT In accordance with public involvement activities requested by the City of Salem under 310 CMR 40.1403(9), notification of the submittal of this IRA Status Report has been made to the Mayor’s Office and the Board of Health. An electronic copy of this report has been provided to the City of Salem Solicitor, Elizabeth Rennard for uploading onto the City’s website for the local community to review rather than navigating through the MassDEP Searchable Sites database. ---PAGE BREAK--- FIGURES ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- TABLES ---PAGE BREAK--- Table 1A Summary of

The portions of these properties are part of the larger Massachusetts Department of Environmental Protection (MassDEP) Disposal Site assigned parent RTN 3-38210 (the “Site”). The Site also includes portions of the properties at 9, 15, and 16 Cedar Road. The IHE was completed as part of the Immediate Response Action (IRA) Status Report #1 submitted by Blackstone Environmental Solutions LLC (BES) to MassDEP. The Site information and analytical soil data provided in the IRA Status Report 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. The BES IRA Status Report details the assessment activities performed at the Site to determine the source, nature and extent of the release condition associated with the formerly Imminent Hazard and to assure the continued absence of any critical exposure pathway (CEP) or a condition of substantial release migration (SRM) from occurring at the Site. Response actions covered by this IRA Status Report #1 are from October 4 through November 30, 2023. Additional data obtained after November 30, 2023 will be included in the IRA Status Report # 2 due to MassDEP on June 5, 2024. BES previously completed an IHE Plan, IRA Plan, and surficial soil sampling at the 330-foot Street Frontage at 14 and 16 Barnes Road. BES filed an Imminent Hazard Evaluation (IHE) Results with MassDEP on October 18, 2023 for a portion of 14 and 16 Barnes Road. The IHE was performed to evaluate the risks associated with the potential trespasser exposure pathway via direct contact to soil at a portion of 14 Barnes Road and 16 Barnes Road. The laboratory soil sampling activities were performed at the aforementioned properties on September 27, 2023. ---PAGE BREAK--- Imminent Hazard Evaluation 12 & 14 Cedar Road and 14 Barnes Road Salem, MA December 2023 5210-11-01 2 The IHE Results concluded that a condition of No Imminent Hazard exists for human health, safety, and the environment exists for the portions of 14 Barnes Road and 16 Barnes Road in Salem, Massachusetts located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road. Also, it was noted that the IHE will be reevaluated if conditions are identified in the future which are materially different from those characterized to date. An IHE Results Amendment was filed with MassDEP on October 20, 2023. Based on feedback received from MassDEP staff on the October 18, 2023 IHE Results submittal, BES filed the Amendment in order to provide more clarity on the specific areas where the risk assessment conclusions were made approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road). 1.1 ADDITIONAL SURFICIAL SOIL SAMPLING Surficial soil sampling activities were completed by BES in November 2023 as part of the IRA assessment program to determine the horizontal extent of PCB and heavy metal contamination at the Site in conformance with the MCP and federal Toxic Substance Control Act (TSCA) requirements. The comprehensive soil sampling program was performed within and around five sampling areas Cedar Road Easement, 12 Cedar Road, 14 Cedar Road, 16 Cedar Road, and 14 Barnes Road) to verify select previous subsurface investigation results performed by others, as well as confirm that the existing security fencing area and natural physical barriers dense forest land, wetlands, bedrock outcrops, surface water body, and steep/rocky terrain) is sufficient to contain/eliminate a “Could Pose” Imminent Hazard to human health. In addition, the data collected from this surficial soil sampling program will be used to aid in developing a supplemental assessment program to determine the full extent of contaminants of concern (COC) impacted soil at the Site, and the implementation of a groundwater assessment program. A total of thirty surficial soil samples (identified as SS-1 through SS-30) were collected from a depth of 0 to 1 foot below grade across the aforementioned sampling areas. Refer to IRA Status Report #1 Figure 2-Site Plan for a depiction of the surficial soil sampling locations. Labelled wood stakes were installed at each sample location and will be surveyed for elevation and location at a later date. The soil samples were analyzed for the following parameters: • PCBs by EPA Method 8082A; • MCP 14 Metals; and • SVOCs via EPA Method 8270 (select samples only). Surficial soil sampling laboratory results are summarized on IRA Status Report #1 Tables 1A and 1B. Soil laboratory analytical reports are provided in IRA Status Report #1 Appendix B. A summary of the laboratory analytical results for the surficial soil samples collected from the five sampling areas indicated the presence of multiple ---PAGE BREAK--- Imminent Hazard Evaluation 12 & 14 Cedar Road and 14 Barnes Road Salem, MA December 2023 5210-11-01 3 target analytes at concentrations exceeding their respective MCP reportable concentrations. During the collection process, a visual surface inspection for ASR material metal, rubber, plastic, wire) was performed within each sampling area. Refer to IRA Status Report #1 Tables 1A and 1B for a summary of where ASR material was visually observed within the investigation areas. 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 was used in the development of Exposure EPCs. No hot spots were identified for the subject portions of the Site. The IHE was focused on the detected PCBs, metals (exceeding MassDEP Background Concentrations for “Natural” Soil [MassDEP, 2002]), and SVOCs as constituents of concern. Maximum detected concentrations were used as EPCs. 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 evaluated in the IHE are currently undeveloped. However, the closest occupied residential building is less than 500 feet away. Existing security fencing area and natural physical barriers dense forest land, wetlands, bedrock outcrops, surface water body, and steep/rocky terrain). However, members of the general public could potentially 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 2023 (sf23tsih) (Method 3 Lookup Tables Version v1123). (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 ---PAGE BREAK--- Imminent Hazard Evaluation 12 & 14 Cedar Road and 14 Barnes Road Salem, MA December 2023 5210-11-01 4 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 30 samples (SS-1 to SS-30) as the maximum detected concentrations of detected analytes (IRA Status Report #1 Tables 1 and These EPCs were input into the Shortform (Table TSIH- 1, 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 hexavalent form. 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). The total IH noncancer risk HI from soil exposure by trespassers is 1.5. 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 2E-06. This value is well below the MassDEP IH cancer risk ELCR of 1E-05. It is noted that a condition of No Imminent Hazard would also exist using the Weston & Sampson maximum concentrations of PCBs (118.3 mg/kg) and chromium (258 mg/kg) in samples collected in 2020. Using these maximum concentrations, the HI (2.4) and ELCR (5E-06) are below MassDEP risk levels for IH. 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: ---PAGE BREAK--- Imminent Hazard Evaluation 12 & 14 Cedar Road and 14 Barnes Road Salem, MA December 2023 5210-11-01 5 • 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 exhibits 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 portions of 12 Cedar Road, 14 Cedar Road and 14 Barnes Road in Salem, Massachusetts located along approximately 330 feet of street frontage existing along the southern boundary for 16 Barnes Road.
