EXHIBIT A WORK ORDER NO. 2 INDIAN RIVER COUNTY LANDFILL SEGMENT 3 CELLS 1 AND 2 LANDFILL GAS SYSTEM EXPANSION DESIGN, PERMITTING, AND BIDDING SERVICES This Work Order No. 2, when executed, shall be incorporated in and become part of the Agreement for Consulting Services between the Indian River County Solid Waste Disposal District (SWDD) and CDM Smith Inc., (CONSULTANT), dated July 18, 2017 hereafter referred to as the AGREEMENT. PROJECT BACKGROUND The SWDD, the owner of the Indian River County Landfill, has requested that CONSULTANT prepare this Work Order to provide professional engineering services for the design, permitting, and bidding for the proposed expansion of the landfill gas collection (LFG) system of Class I Landfill Segment 3 Cells 1 and 2. The proposed locations of LFG header piping and vertical extraction wells after the final buildout of Segment 3 are shown on Drawing No. 27 of the 20 -Year Permit Drawings dated March 2010. Due to current waste elevations, only the final LFG system expansion design for Segment 3 Cell 1 will be included in the final Contract Documents. The LFG system will be preliminarily designed and permitted so that the SWDD can more easily expand into Segment 3 Cell 2 with horizontal gas collectors when conditions are preferable in the future. The Segment 3 LFG system was previously permitted under Construction/Operation Permit Nos: 0128769 -022 -SC and 0128769 -023 -SO and the construction of the LFG system shall be done in accordance with the approved gas management system design. This permit requires notification to the Florida Department of Environmental Protection (FDEP) before any changes to the approved design are implemented to include the proposed horizontal gas collectors into the design and permit. Since new gas extraction wells are being proposed in Segment 3 Cell 2 it is assumed that, at a minimum, a minor modification to the construction/operation permit will be required by the FDEP. Since no changes to the approved gas management system design are proposed in Segment 3 Cell 1, only a courtesy notification will be sent to the FDEP prior to construction activities. The Scope of Services for this project are described below: SCOPE OF SERVICES CONSULTANT will undertake the design, permitting, and bidding of the Class I Landfill Segment 3 Cells 1 and 2 LFG system expansion located at the Indian River County Landfill. The LFG system has already been preliminarily designed and permitted in Segment 3. The permit drawings LFG system plan and details will need to be enhanced to become final design drawings suitable for bidding for construction. Also, additional horizontal collection wells will be added to the proposed design in Segment 3 Cell 2 as part of this project. Therefore, the CONSULTANT will modify/update the existing LFG system permit drawings previously prepared in 2010 by Geosyntec Consultants for the purpose of modifying the permit and bidding the project for construction. �Smith A-1 jj2756_Exhibit A
