Additional Back-up Item 11.A <br />December 17, 2019 <br />Treasure Coast TriCounty Legislative Priorities <br />ADDENDUM: Revised Biosolids Policy Statement <br />(changes are highlighted) <br />Biosolids <br />Today, Florida's central sewer wastewater treatment facilities produce approximately 340,000 tons of <br />biosolids which are the human waste effluents from central sewer wastewater treatment facilities. <br />Approximately 100,000 dry tons of biosolids are designated as Class B biosolids which are treated sewage <br />sludge that meets U.S. Environmental Protection Agency guidelines for land application as fertilizer and are <br />allowed to have detectable levels of pathogens. Another 100,000 dry tons of biosolids are deposited in various <br />landfills throughout the state. The final 140,000 dry tons of biosolids are further processed, dried, and <br />composted with material from the landscape industry to produce approximately 200,000 tons of Class AA <br />biosolids. These biosolids can then be distributed and marketed as fertilizer. This class of biosolids is <br />unregulated and land applied mainly on pasture lands, and to a lesser extent on citrus. <br />Both Class B biosolids and Class AA biosolid fertilizers contain approximately 5.5% Total Nitrogen (TN) and <br />2.2% Total Phosphorus (IT). Therefore, the 300,000 dry tons of land applied Class AA and Class B biosolids <br />C contribute over 33 million pounds of TN and 13.2 million pounds of TP to agricultural lands each year. <br />Wile the practice of land -applying Class B biosolids was recently banned in the Lake Okeechobee, <br />Caloosahatchee, St. Lucie River and Everglades watersheds, the St. Johns River Upper Basin in 2016 received <br />nearly 74,000 tons of Class B biosolids in its watershed. <br />One of the by-products or residuals of the wastewater treatment process is called biosolids, or the wet sludge <br />that is left behind after the initial processing. In Florida, biosolids are either land applied as a soil amendment <br />to improve agricultural productivity or disposed of in landfills. Either way it is an important source of water, <br />energy, nitrogen, and phosphorus resources that some suggest could be recovered and used more efficiently. <br />There is also a concern statewide that excess nutrients from land application of human waste biosolids could <br />reach surface waters because of rainfall runoff and continue to increase the occurrence of chronic harmful <br />algal blooms. <br />ort the efforts of the state and local governments to prioritize the reduction and evc <br />nation of the land application; and compostine of Class Band <br />This includes efforts to immediately establish standard protocols and funding for the <br />identification, quarterly tracking and monitoring of non-residential biosolid and class AA <br />application and explore new wastewater treatment technologies to improve biosolids <br />resource, recovery and management options. <br />0 <br />
