It is believed that the response will include an educational <br />outreach program along with recommendations addressing the outdated Phosphorus Index approach that <br />has been used to determine fertilization rates for certain crops. <br />FDEP staff has indicated that the land application of Class B biosolids within Indian River County has been <br />done in accordance with the receiving site's approved Nutrient Management Plan and under the <br />application program allowed in the FDEP Biosolids Site Permit issued for the receiving site. This is evident <br />from the FDEP site inspection compliance findings that have taken place at the permitted land application <br />sites. <br />Although application rates and procedures meet current regulatory requirements, the marked increase of <br />phosphorus levels identified in BCL appear to have a strong correlation to the increase in Class B biosolids <br />that have been applied in the vicinity of the lake. Consequently, current requirements may not be <br />adequately addressing phosphorus loading from biosolids land application. <br />Since the enactment of Florida Statute 373.4595 in 2007 on the Northern Everglades and Estuaries <br />Protection Program restricting the land application of Class B biosolids in the Okeechobee, St Lucie River <br />and Caloosahatchee River watersheds (effective date of 2012), Indian River, Osceola, and Brevard counties <br />have seen a marked increase in the amount of Class B biosolids applied on agricultural lands. <br />136 <br />
