Township Council Meeting — Packet

Ms. Zayibeth Carballo, PE,PLS,PP,CME,CFM,CFS Director, Municipal Engineer Re: Department of Public Works at 25 Lakeside Avenue – Change Order March 11, 2025 Page 2 Additional two monitoring wells will be installed, and a groundwater sampling at selected 10 monitoring wells will be conducted and analyzed for Metals to determine the extent of the AOC discharge impacts. CME will retain a licensed driller to install the monitoring wells with 2-inch diameter PVC; the wells will be constructed to a depth of approximately (20) feet below ground surface (bgs). The depths and locations of the monitoring wells will be determined based on the findings of the investigations conducted to date to delineate the extent of contaminants identified during the initial sampling event. The wells will be completed with a flush-mount cover. Drill cuttings will be placed in drums and properly disposed off-site at a licensed facility, and development water will be drummed for off-site disposal or properly treated prior to onsite discharge. A professional licensed surveyor will survey the monitoring wells. Well logs and Form A and Form B will be prepared to properly document the well construction. One round of groundwater samples will be collected from ten (10) selected monitoring wells to delineate the impacted groundwater and provide a baseline dataset for further remedial investigation, if needed. Sampling will be performed in accordance with USEPA Low Flow Sampling Procedures (March 1998). Water levels will be measured in all monitoring wells to confirm the groundwater flow direction. Water quality parameters will be directly measured in the field including conductivity, pH, temperature, redox potential, salinity, and dissolved oxygen (DO). All groundwater samples will be submitted for laboratory analysis for TAL Metals in accordance with the TRSR and NJDEP guidance documents. Our estimated cost to complete the additional required services is $19,700. Task 1 2 Description Cost Monitoring Wells Installation $ 10,200 Groundwater Sampling $ 9,500 We appreciate your consideration of the above and would be happy to answer any questions regarding this request.

This proposal encompasses professional site remediation services as requested for the above-referenced property located (the Site). The proposed Scope of Services described below are based on the NJDEP requirements set forth in the Heating Oil Tank System Remediation Rules (N.J.A.C. 7:26F), Administrative Requirements for the Remediation of Contaminated Sites (ARRCS; N.J.A.C. 7:26C), the Technical Requirements for Site Remediation (TRSR; N.J.A.C. 7:26E), NJDEP Field Sampling Procedures Manual (FSPM, November 2022 edition), and applicable NJDEP guidance documents. INTRODUCTION During a 2017 geophysical investigation at the Site a previously unidentified underground storage tank (UST) was identified. The UST is located in the south-central portion of the lot and the anomaly identified during the geophysical investigation was measured to be approximately 6-feet by 10-feet in size, which indicates a potential 1,000-gallon UST. The size, structure, and contents of the UST were not confirmed and there is no available documentation as the UST does not appear to be registered with NJDEP. Based on the historical use of the site as a residence, the UST is assumed to have been used for heating purposes. A review of historical aerial photographs indicates a structure has not been present on the parcel since at least 1974. No staining was observed in the immediate area where the UST was identified. In April 2017 soil samples collected around the perimeter of the UST did not identify detections of Extractable Petroleum Hydrocarbons (EPH). However, as the UST is not currently in-use, the tank needs to be closed in accordance with NJDEP requirements. In

r of the UST did not identify detections of Extractable Petroleum Hydrocarbons (EPH). However, as the UST is not currently in-use, the tank needs to be closed in accordance with NJDEP requirements. In addition to the UST, the Site is located in area that is identified by the NJDEP as mapped historic fill. A review of available historical Sanborn® Maps showed that entirety of the Site was identified as Marsh Land. The potential presence of historic fill at the Site warrants further investigation.

SCOPE OF SERVICES The scope of services and associated fee is described in detail below: ITEM 1: UHOT CLOSURE ACTIVITIES Matrix will provide oversight activities of the unregulated heating oil tank (UHOT) removal and closure activities. For estimation purposes, it is assumed the closure activities will be completed in two (2) days. Matrix will retain a licensed tank removal contractor to properly decommission the UHOT in accordance with applicable regulations and NJDEP guidance documents. The UHOT will be uncovered, cleaned, removed, and set on poly sheeting for inspection by local official. Once inspection has been conducted, the UHOT will be properly disposed. For purposes of this proposal and based on the previous sampling results, it is assumed no impacted soil will be removed for off-site disposal. The UST excavation will be backfilled with clean overburden and approximately 15 tons of imported certified clean fill backfill material. Costs are also included for disposal of up to 500 gallons of oil and residuals by vacuum truck. Upon removal of the tank, Matrix will collect post-excavation soil samples for laboratory analysis, described below. If no groundwater is encountered, soil samples will be collected, every 5 feet, along the centerline of the tank invert (two samples). In addition, four sidewall samples will be collected from the excavation and placed on hold, pending the results of the centerline samples. If groundwater is encountered within the excavation, only the sidewall samples will be collected and will be automatically analyzed. All soil samples will be submitted for laboratory analysis for Category 2 extractable petroleum EPH with contingent analysis for polycyclic aromatic hydrocarbons (PAHS) on 25% of those samples were EPH is detected at a concentration above 100 milligrams per kilogram (mg/kg), pursuant to N.J.A.C. 7:26E-2.1. For the purposes of this proposal, it is assumed that up to six (6) soil samples will be submitted for total EPH analysis and up to two (2) soil samples will be further analyzed for PAHs. All samples will be submitted for analysis to a NJDEP-certified laboratory on a standard turn-around time. Note: Based on the findings of the UHOT removals, further investigation and/or remediation may be warranted. This proposal does not include costs associated with additional investigation/remediation services. Estimated

findings of the UHOT removals, further investigation and/or remediation may be warranted. This proposal does not include costs associated with additional investigation/remediation services. Estimated Cost (Time and Material) Item 1 ITEM 2: $14,700.00 HISTORIC FILL EVALUATION In order to evaluate the potential presence of historic fill material at the Site, Matrix will install two test pits within the suspected historic fill area to a depth of two feet below the fill material to determine the vertical and general horizontal extent of the fill. Matrix will collect two soil samples (one from each test pit), in accordance with the NJDEP Historic Fill Material Technical Guidance document dated April 2013. One sample will be submitted for Target Analyte List (TAL) Metals and PAHs. The second sample will be analyzed for EPH and the full Target Compound List/Target Analyte List (TCL/TAL) analytical suite. For the purposes of this proposal, it is assumed the historic fill samples will be collected during the UST closure activities. Estimated Cost (Time and Material) Item 2: $3,400.00

ITEM 3: REPORTING Matrix will prepare a Remedial Action Report (RAR) in accordance with N.J.A.C. 7:26E-5.7. The report will document the field activities, results, findings and conclusions of the UHOT closure activities. The report will include laboratory reports, analytical summary tables, and maps that document the sample locations and results. Based on the findings of the remedial activities, recommendations will be provided for additional investigation and/or remedial action, if warranted. Matrix will also prepare the required UHOT System Remediation Form. On behalf of Client, Matrix will submit the UHOT form, RAR, and required $400 fee to the NJDEP. A separate summary report will be prepared for client detailing the findings from the historic fill evaluation. The summary letter will include data summary tables, a map depicting the sample locations, analytical summary tables, and recommendations to address the presence of historic fill at the Site, if necessary.
