September 29, 2017 WN Fire House No, 4, 280 Pleasant Valley Way & avi TWOROH-17002 Page 2 initial USTs Facility Questionnaires to the NJDEP or any past-due USTs registration fees for the existing USTs. If these items are required, the scope of work presented herein will require revision, and a proposal will be submitted to the Client for approval prior to addressing such items. Task 2: USTs Removal/Closure Supervision and Soil Sampling It is our understanding that the Client will be independently selecting a NJDEP-certified UST contractor to perform the two USTs closure, and site restoration services. T&M will provide oversight during the removal of the two USTs by the NJDEP-certified UST contractor retained by the Client directly. T&M will provide a Sub-Surface Evaluator to provide on Site supervision inspection during the course of the two USTs removal/closure and backfilling operations to verify that these operations are performed in accordance with the NJDEP regulations, recommended industry procedure and permitting requirements. For the purpose of this proposal and budgeting purposes, T&M anticipates two (2) days of field activity and management to oversee the closure of the two USTs, collection of post-closure/excavation soil sampling and backfilling activities. The on-Site services will include: ° Visual observation of the two UST systems and piping during and subsequent to closure to verify the integrity of these structures in order to evaluate the potential that previous leaks and/or uncontrolled product discharges may have occurred. @ Implement field screening methods in accordance with the protocols detailed in the NJDEP Field Sampling Procedures Manual (August 2005). © Inthe absence of obvious petroleum product impacted areas, T&M will initiate the post-closure soil sampling and analysis protocols specified in the NJDEP Technical Requirements for Site Remediation (N.J.A.C. 7:26E-3) for the two USTs and piping (one [1] sample required per 15 linear feet of product piping) and conform to NJDEP closure obligations and LSRP direction. Soil Sampling at 2,500-gallon capacity diesel fuel UST: Nine (9) soil samples will be collected based on field observation and field screening to document UST/piping closure. Soil samples will be analyzed for Extractable Petroleum Hydrocarbons (EPH) with a contingency for 2- methylnaphthalene and naphthalene

d observation and field screening to document UST/piping closure. Soil samples will be analyzed for Extractable Petroleum Hydrocarbons (EPH) with a contingency for 2- methylnaphthalene and naphthalene for 25% of all soil samples that exhibit EPH impact greater than 1,000 parts per million. Per NIDEP QA/QC requirements, one (1) field blank and one (1) trip blank will also be submitted for laboratory analysis. Soil Sampling at 1,000-gallon capacity unleaded gasoline UST: Eight (8) soil samples will be collected based on field observation and field screening to document UST/piping closure. The soil samples will be analyzed for EPA Target Compound List volatile organic compounds (TCLVO+15) with a library search of the fifteen (15) highest Tentatively Identified Compounds (TICs) and tertiary butyl alcohol (TBA). All soil samples will be submitted to a NJDEP-certified analytical laboratory for analysis to evaluate the potential that discharges from the subject UST systems have impacted the Site. Upon the closure of the two USTs, T&M will prepare and submit two revised UST Facility Certification Questionnaires documenting the closure and requesting the delisting of the two USTs on the NJDEP database.
