This is a service / maintenance or supply contract in Scottsdale, Arizona. Contact the soliciting agency for additional information.

There were three landfills located within the boundaries of SRPMIC. The North Center Street Landfill (30 acres) and the Tri-Cities Landfill (230 acres) both closed in 1993, and the Salt River Landfill (currently 144 acres) opened in their place. Although two of the landfills within SRPMIC boundaries have been closed for 30 years, they are still producing landfill gas (LFG), which is currently collected from all three sites and flared to combust the CH4 and effectively convert it to CO2, thereby reducing its global warming potential (GWP). The North Center Street Landfill only produces about 100 cubic feet per minute (cfm) of LFG, the Tri-Cities Landfill produces 500-600 cfm of LFG (which is declining due to the landfill being closed) and the Salt River Landfill produces about 1,500 cfm of LFG (increasing as the landfill accepts more waste). A Landfill Gas Reuse Project (Project) was proposed that would utilize the LFG currently being collected and flared to produce renewable natural gas for either injection into a pipeline owned and operated by the City of Mesa, AZ, or compression and transport via specialized trucks to various end-users. It is estimated that the total cost of the Project would be between $25 million to $40 million and could provide benefits to the Community such as a reduction in odor, additional revenue stream, jobs creation, and carbon footprint reduction. As part of the identified work, the consultant will need to complete a Feasibility Study prior to the commencement of the Project. This Study needs to provide a comprehensive breakdown of how the Project would be structured and executed under two scenarios: Taking the LFG and transforming it for distribution either by physical pipeline to a neighboring city (Mesa) in which additional pipeline would need to be designed and developed, or injection into a "virtual" pipeline for distribution to multiple users. The Feasibility Study would also need to address the overall benefits, stressors, costs, and profit potential of both scenarios. In addition, the two Project options would need to be weighed against a "do-nothing" approach in which the Project is not feasible and does not proceed. The Feasibility Study should also examine aspects such as funding sources, and right-of-way, maintenance, and safety issues. The consultant will need to work with staff from the SRPMIC's Community Development Department, Engineering & Construction Services, and the Salt River Landfill, as well as staff from DTE Energy and possibly the City of Mesa to gather necessary information.
