• Using industry estimates of $8 per acre cost to land apply biosolids <br />at 500,000 acres would equate to approximately $4 million new <br />recurring costs (industry estimates $17 million.) <br />• Industry believes that the remaining land in Florida acceptable for <br />this land application is limited; some of this area is within springs <br />watersheds. Industry predicts having to use disposal sites in North <br />Florida and South Georgia, adding 150-350 miles to biosolids <br />transportation at a cost of $3.00 per mile. Using 90,000 dry tons or <br />450,000 wet tons, each truck carrying 25 wet tons equals 18,000 <br />loads at a round trip of 500 miles (250 mile trip). At a cost of <br />approximately $3 per mile, this equals $27 million annually. Industry <br />estimates $42 million annually. <br />Additional monitoring (no new sites): $1 million annually <br />• Ground water — if all 125 sites, (3 wells each), require quarterly <br />monitoring of $500 per quarter, this totals to $750,000 annually. <br />• Surface water monitoring — This is not required for all sites, but there <br />are likely multiple locations possible per site. An approximate <br />estimation is 125 samples quarterly at $500 per sample, which totals <br />to $250,000 annually. <br />Converting to Class AA (Fertilizer) <br />Estimated capital cost: $300 million - $400 million <br />• Miami -Dade County's estimate for Class AA: $100,000,000 <br />• Miami -Dade represents about 25-33% of Class B biosolids currently <br />land applied. <br />• St.j Petersburg reported spending approximately $94 million for a <br />Class AA project, which will treat a smaller quantity of biosolids. The <br />facility may need modifications, which will add to the current <br />expense. <br />• Smaller facilities do not have the scale to achieve the same capital <br />cost per dry ton as Miami -Dade, so the Miami Dade estimate could be <br />conservative. <br />• Private regional facilities serving small facilities would reduce capital <br />costs, but would increase operational costs (e.g. transportation, and <br />dewatering) <br />Estimated recurring cost: $30 million - $40 million <br />• Miami -Dade estimate is $10 million Operation &Maintenance <br />annually. <br />• Miami -Dade represents about 25-33% of Class B biosolids land <br />applied. <br />• Smaller facilities do not have the scale to achieve as low a cost per <br />dry ton as Miami -Dade. <br />• Regional facilities would also not have the same scale as Miami <br />Dade, due to the county's dense population compared to the less <br />dense area that a regional facility could serve. Regional facilities <br />would also have higher transportation costs. <br />146 <br />
