NJ 07052 Re: PROPOSAL FOR ENVIRONMENTAL SERVICES TOWNSHIP OF WEST ORANGE MULTI PARK DEVELOPMENT LAFAYETTE PARK BLOCK 61, LOT 27 PARK AVENUE AND MAIN STREET WEST ORANGE, NEW JERSEY NJDEP’s PROJECT NO. 0722-17-035 MATRIX NO. P17-707 Dear Mr. Lepore: As requested, Matrix New World Engineering, Land Surveying and Landscape Architecture, P.C. (Matrix) is pleased to provide this proposal to perform environmental services for the above-referenced Site. The proposed work encompasses general professional environmental services in support of the Township of West Orange’s Green Acres Program requirements administered by the New Jersey Department of Environmental Protection (NJDEP). In addition, 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, and the Technical Requirements for Site Remediation (TRSR), N.J.A.C. 7:26E. Matrix prepared a Preliminary Assessment Report (PAR) for the above-referenced Site on October 20, 2017. The PAR identified a total of nine (9) Areas of Concern (AOCs); no further investigation was proposed for seven AOCs. Further investigation was proposed for AOC-6 (Non-Indigenous Fill) and AOC-8 (Potential

AR identified a total of nine (9) Areas of Concern (AOCs); no further investigation was proposed for seven AOCs. Further investigation was proposed for AOC-6 (Non-Indigenous Fill) and AOC-8 (Potential Heating Source of Former On- Site Structures). Based on NJDEP’s November 2, 2017 letter, the PAR was reviewed, and each recommendation was supported by NJDEP’s Green Acres Program. Therefore, the scope of work for this proposal includes site investigation activities and associated reporting to further investigate AOC-6 and AOC-8. SCOPE OF WORK The scope of services and associated fee is described in detail below: Task 1: Soil Site Investigation and Geophysical Investigation Matrix will perform a Site Investigation (SI) at the Site consisting of both a geophysical survey and the advancement of soil borings. A geophysical survey will be completed using ground penetrating radar (GPR) and other associated technologies to evaluate the Site for past usage. Specifically, the geophysical survey is to document whether any wells, septic systems, or underground storage tanks (USTs) or other potentially historical or buried anomalies were ever associated with structures on the property. A direct-push drill rig will be utilized to collect soil cores. Soils will be logged, and the extent of non-indigenous fill material determined. Soil samples will be collected from within the non-indigenous fill material only and analyzed pursuant to NJDEP’s April 2013 Historic Fill Material Technical Guidance document. Based on an approximate Site area of 1.7 acres, a total of four soil samples will be submitted for analysis. Three soil samples will be submitted for target compound list polynuclear aromatic hydrocarbons (TCL PAHs) and target analyte list (TAL) metals. One soil sample (25% of the total samples collected) will be submitted for F:\2017\17-707 Twp. of West Orange Preliminary Assessments - Green Acres\Proposal\2018-02-02_Lafayette-SI\Revised\Twp. of West Orange - Lafayette Park_Revised.DOC 1
