The Department is proposing to amend Chapter 62-701, Florida Administrative Code (F.A.C.), which contains regulations for a wide variety of solid waste facilities including landfills, construction and demolition (C&D) debris disposal facilities and waste processing facilities. This chapter was substantially revised on May 21, 2001. Since that time, technologies have progressed and statutes have been changed making it apparent that an update of the entire chapter was necessary. Furthermore, new research has shown that arsenic may leach from wood treated with chromated copper arsenate (CCA) at concentrations above the Department's groundwater standard. Since most of this wood is currently disposed of in unlined facilities in Florida, the Department has concluded that Florida's groundwater may be at risk. It is clear that better management practices are needed.
