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 Cost

ings 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 $14,700.00 ITEM 2: 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
