TOWNSHIP OF WEST ORANGE, ESSEX COUNTY, NEW JERSEY FORMER BIDDELMAN, INC. 4-10 CENTRAL AVENUE, BLOCK 9, LOT 32 WEST ORANGE, NEW JERSEY NJDEP SRP PI NO. G000006148, ISRA CASE NOS. E200050486 & E86699 NJDEP CASE NO. 17-04-20-1128-26 MATRIX NO. 18-286 Dear Ms. Carballo & Mr. Smeraldo: Matrix New World Engineering, Land Surveying and Landscape Architecture, PC (Matrix) is pleased to present this proposal to the Township of West Orange (Township) for the above referenced activities at the Former Biddelman, Inc. (Site) property located at 4-10 Central Avenue (Block 9, Lot 32) in the Township of West Orange, New Jersey. The Site is approximately 0.93-acres, rectangular in shape, and is currently improved with a two -story cinder block building on a concrete slab foundation (9,900 square-foot building) that has been vacant since 2004. The remainder of the Site consists of an asphalt paved and gravel parking lot, and a small grassy area. The existing building is pending demolition by Blue World Construction prior to Site remediation and redevelopment. In an effort to reduce overall redevelopment costs for the Township, Matrix completed in-situ building material characterization sampling to identify material associated with the existing building that may be utilized as fill for beneficial reuse during redevelopment of the Site. SCOPE OF WORK Matrix proposes to conduct limited oversight during demolition activities to ensure areas of the building that qualify as “fill for beneficial reuse” are properly segregated from impacted material that will require off-site disposal, following demolition. This scope of work for the oversight is based on the Blue World Construction Bid submitted on June 23, 2025, for the demolition of the Biddelman Building. The bid from Blue World Construction is based on the May 2025 Limited Demolition Specifications, April 2025 Summary of Concrete Sampling Activities, February 2025 Regulated Building Material Investigation Report, and the May 2025 materials Management Plan. All

5 Limited Demolition Specifications, April 2025 Summary of Concrete Sampling Activities, February 2025 Regulated Building Material Investigation Report, and the May 2025 materials Management Plan. All activities will be overseen and directed by a Matrix Licensed Site Remediation Professional (LSRP). A more detailed scope of services is presented in the Tasks summarized below. Task 1 – Building Demolition Oversight Building demolition will occur following completion of asbestos abatement activities. Matrix understands that abatement activities will be conducted by a licensed New Jersey Department of Labor (NJDOL) asbestos abatement subcontractor that has been retained by Blue World Construction. Asbestos abatement monitoring and air sampling services are included in the Bid from Blue World Construction. Matrix conducted characterization via in-situ sampling of the building materials (i.e., concrete slab, cinder block walls, and exterior brick walls) to determine if the material would quality for on -site beneficial reuse as fill during redevelopment. Based on the results of the building material sampling conducted by Matrix, all cinder block and brick can be utilized as beneficial reuse fill on-site. However, portions of the concrete floor slab on both the first and second floor of the building require segregation and off -site disposal at an approved facility, as summarized in the Concrete Sampling Letter Report submitted in April 2025, and the Materials Management Plan submitted in May 2025 by Matrix to the Township.
