96-25 Exhibit A.pdf

The PA is designed to meet the diligent inquiry requirements of the Technical Requirements for Site Remediation (Technical Regulations) at N.J.A.C. 7:26E-3.1 and 3.2 to determine if there may be potentially contaminated areas of concern (AOCs) that require further investigation. PA Report An electronic DRAFT report will be issued for your review and comment. Upon receipt and consideration of your comments, the FINAL report will be issued upon your authorization. The FINAL report will be provided in electronic format via electronic mail, or via a cloud-based link if the file size is too large to email. Task 2 – Geotechnical Engineering Services Matrix will review any available documents pertaining to the site which may include pertinent information to be used in this task. Matrix will provide geotechnical engineering services to investigate subsurface conditions and evaluate their impact on proposed construction. Matrix will prepare the subsurface exploration program which will include a boring location plan on a CAD base plan (to be provided by the client) and proposed sampling depths and intervals. The planned scope of services is described below. Subsurface Investigation Prior to the subsurface investigation, the client shall provide a site location plan detailing utility locations currently servicing the site. Matrix anticipates completing 2 to 3 geotechnical borings to depths of 30 to 50 feet below grade (unless refusal is encountered shallower). Matrix has allotted for 1 day of drilling and an anticipated program will be determined prior to mobilization. It is anticipated that a rubber track ATV or truck rig will be utilized for the borings and that access to the boring locations is assumed to be feasible. Standard split spoon sampling will be conducted in each boring continuously to a depth of 12 feet below the ground surface (bgs), and at nominal five-foot intervals thereafter, if the conditions warrant. Split spoon samples will be collected using the Standard Penetration Test (SPT) in accordance with ASTM D1586, Standard Method for Penetration Test and Split-Barrel Sampling of Soils. Matrix will lay out the borings by taping and line of sight measurement using mapping provided by the client and will provide full-time technical observation of the field operations, including logging of the subsurface materials and collection of samples. Samples

surement using mapping provided by the client and will provide full-time technical observation of the field operations, including logging of the subsurface materials and collection of samples. Samples obtained during the exploration program will be returned to Matrix’s office for further examination and testing, as warranted. If contaminated soil or groundwater is encountered that is deemed detrimental to the health and safety of the field staff, the boring will be terminated and backfilled and the client notified. Matrix will prepare a supplemental proposal for completing the investigation with the required increases in PPE and additional environmental precautions. The drilling subcontractor will contact the One Call service for general utility mark-out. Additionally, a GPR survey will be conducted to clear all proposed test borings. Borings advanced greater than 25 feet in depth will be grouted to the ground surface. Excess drill cuttings will be raked adjacent to the borehole. Soil samples collected during this evaluation will be discarded after six months of the completion of the subsurface investigation unless the client arranges to retrieve the samples from Matrix’s storage facility prior to that time. 3
