OC Waste & Recycling (OCWR) - OCWR is the owner and operator of Coyote Canyon closed landfill. Archaea is partnering with OCWR for a mutually beneficial project to create renewable energy from landfill gas produced at the closed landfill. OCTOBER 14, 2025 Who We Are At A Glance 11 _'N The largest Renewable Natural Gas (RNG) producer by volume in the US. Industry -leading RNG platform, with 14 RNG facilities and 31 landfill gas to electric facilities (LFGTE), 3 medium BTU plants & 4 O&M Focused on end -to -end development of RNG facilities to transform waste emissions into low carbon fuel; primary focus on landfill gas (LFG) as feedstock Technology -driven approach, paired with gas processing expertise, advances operational excellence, project timelines and lowers development costs Differentiated commercial strategy, focused on long-term commercial partnerships that provide a multi -decade decarbonization solution to displace fossil fuels OCTOBER 14, 2025 Located in 32 states and growing 50 operated sites across the US Safety ➢ Safety is a core value and our highest priority. ➢ Archaea follows a rigorous health and safety training regimen to ensure they are familiar with equipment and procedures. ➢ Archaea establishes written policies and site -specific safety plans designed to comply with all local, state, and federal laws and standards. OCTOBER 14, 2025 ➢ Archaea engages in both preventive maintenance and performs equipment checks twice a day. ➢ Archaea is committed to ensuring the health and safety of all onsite personnel, as well as that of the environment and the community, during the construction and operation of every plant.

CH4 is converted to CO2, processed. CH4 is upgraded into atmosphere. which is less destructive to the pipeline -quality RNG. This approach atmosphere. This approach captures and beneficially uses over captures up to 90% of the CH4, but 90% of the CH4 and reduces site it is not used beneficially emissions. by ARCHAEA 0**' L ENERGY a company Landfill Gas Decomposing organic waste Average starting composition: 50 % Methane / 40 % CO, / 9 % Nitrogen / naturally releases biogas. 1 %02/ —500 ppm HiS fully saturated R WASTE CONNECTIONS COMPANY 2 3 Vacuum Service H2S Treating: Vacuum pressure is applied to landfill to satisfy wellfield emissions.

The reduced emissions encompasses CO2, methane and nitrous oxides. ❑ Revenue generation for the county. ➢ This process will generate revenue for the county from the sale of the LFG that would have otherwise been flared. ❑ RNG fuel security and natural gas fuel diversity. ➢ This project reduces the dependence on fossil fuels and supports California's carbon neutrality goal. FE ARCHAEA XX ENERGY a by company What Will Local Communities Notice? ➢The City of Newport Beach has engaged a California Environmental Quality Act (CEQA) consultant who will assess the project's impacts on the community as well as Archaea's mitigation measures. ➢The short-term impacts of this project to the community may include increased truck traffic, potential visual obstruction from construction equipment, noise and dust emissions. ➢ Archaea Energy has carefully assessed these effects and is implementing measures to minimize its impact on the community. ➢ Archaea Energy will coordinate with the neighboring community during all phases of the construction process.
