The Public Utilities Board recommends approval (5 - 0). STRATEGIC ALIGNMENT This action supports Key Focus Area: Promote Sustainability and the Environment. INFORMATION/BACKGROUND In 2020, the City commissioned a study on possible Landfill Gas-to-Energy (LFGE) projects at the landfill, with the refinement of the gas into high-Btu fuel for export into a nearby natural gas pipeline owned by Atmos being the preferred option. The City, working with an outside consultant, developed a Request for Proposals (RFP) to identify an experienced, qualified company to design and construct an LFGE plan to clean the gathered landfill and treatment plant gas and sell it on the open market. The City will cost-share with the successful operator. Additional biogas for this project will be provided for the project from the Pecan Creek Wastewater Treatment Plant (WWTP). This is a revenue-generating contract; the City shall receive an allocation of the Net Sales Revenue from the sale of Gas to Third Party Purchasers, subject to the terms and conditions. Mayhill Renewables offered the best proposal and the highest price for One Million British Thermal Units (MMBtu) of Renewable Gas sold to a third party (Atmos Gas). Project Facilities Construction Cost Recovery Mayhill Renewables will assume wellfield operations about 6 months prior to the project coming online. Once onsite, they will complete a detailed evaluation of the wellfield and develop plans to bring the wellfield to their standards. Mayhill Renewables will complete a large wellfield construction effort that will include about 70 new wells with the goal of exceeding 90% efficiency and a flow of at least 2,500 standard cubic feet per minute (SCFM). City Hall 215 E. McKinney Street Denton, Texas www.cityofdenton.com For the use of the approximately 1.7 acres of landfill, Mayhill Renewables will pay a monthly lease to the City. Request for Proposals was sent to 485 prospective suppliers of this item, including 22 Denton firms.

Nine (9) proposals were received, references were checked, and proposals were evaluated based upon published criteria, including similar projects and references, project approach and schedule, qualifications and financial resources, and price.

RECOMMENDATION Award a contract with Mayhill Renewables, LLC, to design, fabricate, construct, commission, and operate a Renewable Natural Gas (RNG) Facility to treat landfill and digester gas at the City of Denton Landfill for the Solid Waste and Water Utilities Departments, in a twenty (20) year term. PRINCIPAL PLACE OF BUSINESS Mayhill Renewables, LLC Midland, TX SUSTAINABILITY MEASURES Currently, to manage the landfill gas as required by Texas Commission on Environmental Quality regulations, all landfill gas is diverted to a flare station, then flared off (destroyed). The flare requires a major maintenance expense as well as the electrical need for mechanized components, resulting in a revenue loss. Landfill gas can be considered an asset for the City of Denton, as it produces a financial profit. This asset is being protected and utilized efficiently. Many advantages are gained by producing a clean, reusable landfill gas. Air quality is improved by not producing possible gas emissions, therefore minimizing greenhouse gas emissions. Gaining a financial profit is advantageous versus losing this byproduct by destruction is a sensible alternative. All governing and operating permits will be secured by Mayhill Renewables, LLC. to ensure all environmental needs are met. Mayhill Renewables can provide and maintain a software program or website for the project to share information, manage documents, and publish reports and information to keep all those involved informed on all aspects of the project. ESTIMATED SCHEDULE OF PROJECT This project will be started upon approval. A timeline will be provided by Mayhill Renewables for the development and construction, and then the operations aspect of the project. This is a twenty (20) year contract with options to terminate by either party. FISCAL INFORMATION This is a revenue-generating contract; the City shall receive an allocation of the Net Sales Revenue from the sale of Landfill Gas to Third Party Purchasers.
