Township Council Meeting - Thursday — Packet

Prior to demolition activities, Matrix will demarcate the areas on both the first and second floor of the building where impacts have been identified and delineated. These areas of the concrete slab will require segregation during demolition and off-site disposal at a New Jersey Department of Environmental Protection (NJDEP) approved facility . Matrix will coordinate with the demolition contractor to ensure the impacted concrete slab is properly segregated from material to be reutilized as beneficial use fill and staged on plastic or loaded into roll -off containers for off-site disposal at an approved landfill. Construction debris that qualifies for beneficial reuse including building foundation footings, will be crushed and stockpiled separately for future reuse as fill during Site redevelopment. Based on the Bid from Blue World Construction, Blue World is anticipating being on-site for approximately 41 days. Matrix has budgeted oversight for four hours a day for a total of ten days. Task 2 – Waste Classification Sampling (if required) The demolition contractor will be responsible for contracting with an appropriate disposal facility to accept the impacted portions of the concrete building slab. Building material sampling conducted previously by Matrix identified Extractable Petroleum Hydrocarbons (EPH), tetrachloroethene (PCE), and several metals including cadmium, copper, and lead in the concrete, at concentrations exceeding the NJDEP applicable soil remediation standards (SRS). Although data exists from the building material sampling to provide to the disposal facility selected by the demolition subcontractor, additional analysis may be required based on the requirements of the chosen disposal facility before the material can be accepted by the facility. Therefore, additional waste classification sampling may be required based on the receiving facility sampling requirements. Since the specific receiving facility is unknown, Matrix assumes up to two (2) additional waste classification samples will be collected from the impacted material, if required. The samples will be submitted to a New Jersey certified laboratory and analyzed for Full Toxicity Characteristic Leaching Procedure (TCLP), total polychlorinated biphenyls (PCBs), and reactivity, ignitability, and corrosivity (RIC). The sample s will be analyzed on a standard 7-day turnaround time (but is

ristic Leaching Procedure (TCLP), total polychlorinated biphenyls (PCBs), and reactivity, ignitability, and corrosivity (RIC). The sample s will be analyzed on a standard 7-day turnaround time (but is budgeted for 3-day turnaround time due to potential time constraints). Upon receipt/evaluation of analytical results, Matrix will submit the required documentation to the receiving disposal facility for approval, transportation and off-site disposal. Task 3 – LSRP Oversight and Project Management This task includes project management and the anticipation of future conference calls and/or meetings with the project team. As a part of this task, the Matrix LSRP will oversee the activities outlined above. Please note that the disposal of the concrete and beneficial reuse of fill on the Site will be captured in the Remedial Action Report to the NJDEP. Reporting costs to the NJDEP are not included in this proposal. COSTS All work will be conducted in accordance with the previously transmitted standard terms and conditions and LSRP Special Provisions. It is proposed that this work will be performed on a time & material not-to-exceed basis. The following are our estimated costs for the tasks described herein.
