SCS FIELD SERVICES <br />Environmental <br />Consulting & Contracting <br />June 26, 2020 <br />Brian Lewis <br />Landfill Operations Manager <br />Republic Services <br />1327 74th Ave SE <br />Vero Beach, FL 32968 <br />Subject: Proposal to Install Landfill Gas Well Dewatering Pumps Revision One <br />Indian River Landfill, Vero Beach, Florida <br />Dear Mr. Lewis: <br />SCS Field Services (SCS) is pleased to provide this proposal to you for the subject work. SCS -FS is <br />prepared to purchase materials immediately upon receipt of approval and schedule the work in a <br />timely manner. The budgetary estimate is outlined below. <br />SCOPE OF WORK <br />In April and May SCS -FS performed the first round of the semi-annual liquid level monitoring for <br />2020. This was the first time the vertical wells that were installed during the 2018 GCCS expansion <br />were measured for liquid. A summary of this data is included in Table 1. Based on this initial round <br />of liquid level measurements SCS -FS has identified 1.8 vertical wells that have a column of liquid that <br />is blocking at least half of the section of perforated pipe and restricting gas extraction flow rates. A <br />graphical representation of the 18 wells is presented in Figure 1. SCS -FS recommends installing <br />new pneumatic pumps in each of these wells to draw down the liquid level. <br />SCS -FS will provide the labor, equipment and materials to install 13 new QED AP -4+ bottom loading <br />pneumatic pumps and hardware for each of the proposed well locations. SCS -FS will install reducers <br />and transition fittings on the existing air and force main riser pipes at each of the wells to service the <br />pumps. Once the pumps are installed, they will be activated and checked for proper operation. In <br />addition 5 of the existing dewatering pumps will be removed from vertical wells where they are no <br />longer needed and install them in the remainder of the 18 new wells identified. <br />COMPENSATION <br />SCS can purchase materials and install based on the costs listed below: <br />Description <br />Price per Pump <br />Qty. <br />Total <br />Labor, Equip., Materials and Installation (new) <br />$5,850 <br />13 <br />$76,050.00 <br />Remove and Install Existing Pumps <br />$625 <br />5 <br />$3,125.00 <br />Total: <br />$79,175.00 <br />1900 NW Corporale Ave, Suite E300, Boca Roton.
