nature of HFM at the Site. Based on the location of the potential HFM, Matrix proposes the installation of a limited number of soil borings to complete the SI activities. The proposed work will be completed in accordance with the Site Remediation Reform Act (SRRA), N.J.S.A 58:10C-1 et seq., the Administrative Requirements for the Remediation of Contaminated Sites (ARRCS), N.J.A.C. 7:26C, the Technical Requirement for Site Remediation (TRSR), N.J.A.C. 7:26E, and the NJDEP’s Historic Fill Material Technical Guidance document (April 2013). Task 1 – Phase II Site Investigation Activities Based on the NJDEP GIS Map and NJDEP’s GeoWeb, there is potential for impact s associated with HFM in limited areas along the eastern portion of the Site. Matrix will mobilize to the Site with a New Jersey-licensed driller to oversee the installation of six (6) soil borings throughout the mapped areas of HFM utilizing Geoprobe ® Direct Push technology to determine if HFM is present and, if present, determine the nature and general extent of the HFM. The Geoprobe samples will be lined with five-foot dedicated acetate sleeves and advanced to approximately 10 feet, below grade (ft, bg). The material collected within each boring will be field-screened for the presence of volatile organic compounds (VOCs) with a photo-ionization detector (PID) and visually inspected for the presence of HFM. If HFM is identified, it can be assumed that soil and groundwater is impacted without sampling. When assuming HFM is impacted, an LSRP will need to be retained, and a Confirmed Discharge Notification (CDN) must be submitted to the NJDEP. In addition, institutional (i.e., Deed Notice for soil and Classification Exception Area for groundwater) and engineering controls (i.e., capping and/or fencing to restrict access to the areas) will be required. A Remedial Action Permit (RAP) for soil and groundwater will also need to be applied for with the NJDEP prior to the submission of a Response Action Outcome (RAO) by the LSRP. A separate proposal will be prepared should it be determined that historic fill is present for either the delineation and sampling of the material to confirm it is impacted and/or the completion of a Deed Notice/CEA and RAP for soil and groundwater if assuming impacted (no sampling) or confirmed impacted (with sampling). Task 2 – Phase II Report Preparation and Project

d and/or the completion of a Deed Notice/CEA and RAP for soil and groundwater if assuming impacted (no sampling) or confirmed impacted (with sampling). Task 2 – Phase II Report Preparation and Project Management Following receipt of the results, Matrix will prepare a SI report detailing the results of the work completed as part of Task 1. A draft report will be prepared 30 days after the last set of data is received. A final report will be submitted two weeks following receipt of client comments.
