2 Sanitation began Collection & Disposal of MSW Seminole Landfill began disposal operations Collection - MSW 160,000 Residents & 8,500 Businesses Disposal 1,400 Tons per Day Density 1,850 lbs per cubic yard Compost as Cover Site Life & Disposal Capacity 2110

3 2000 Started Flaring Landfill Gas Today Generates 2,400 scfm of raw LFG Future Projection 4,200 scfm of raw LFG by 2022 Site has a Non-Attainment rating of 25 Tons of NOx Green Energy Facility 3.2 MW of Electricity (First - Georgia Power Renewable Electricity Program) 4.2 Years ROI - Return on Capital Investment Electricity Generation uses 1,100 scfm of raw LFG
