The chapter is being amended in several places to address the requirement that expansions of existing and new C&D debris disposal facilities be equipped with liners and leachate control systems unless the owner or operator can demonstrate that such systems are not required. For C&D debris facilities that must install liners and leachate control systems, additional requirements also become necessary for leachate storage, closure and gas controls at these facilities. Although included in the rule development workshops, this proposed rulemaking does not include amendments for the provision of subsection 403.707(9)(g), F.S., which directs the Department to develop rules that require, to the extent economically feasible, all construction and demolition debris be processed prior to disposal, either at a permitted materials recovery facility or at a permitted disposal facility. The Department intends to receive additional public input prior to publishing a separate notice of proposed rule to complete this specific rule development effort. For all solid waste disposal facilities, the proposed rule provides clarifications for the requirements when evaluating the potential for sinkholes. The proposed rule provides specific conditions for allowing disposal facilities to use on-site soils in their closure plans to lower closure cost estimates. Waste processing facilities that accept Class III wastes would be able to use ground water monitoring in lieu of leachate controls if certain operation criteria are satisfied. Other simplifying changes and technical corrections or updates are also proposed for this chapter. OTHER RULES INCORPORATING THIS RULE: 62-210.200, 62-340.700, 62-521.400, 62-600.300, 62-600.410, 62-600.740, 62-620.620, 62-625.420,62-640.100, 62-640.860, 62-660.803, 62-709.201, 62-709.300, 62-709.320, 62-709.460, 62-709.510, 62-709.600, 62-710.201, 62-710.210, 62-710.401, 62-710.800, 62-711.300, 62-711.400, 62-711.500, 62-711.520, 62-711.530, 62-711.550, 62-711.801, 62-713.200, 62-713.220, 62-713.300, 400, 62-713.600, 62-780.150, 62-780.500, 62-780.600, and 62C-16.0051. EFFECT ON THOSE OTHER RULES: Amendments to Chapter 62-701 in this Notice of Proposed Rule are not expected to have any significant impact on the following rules: 62-210.200, 62-340.700, 62-521.400, 62-600.300, 62-600.410, 62-600.740, 62-620.620, 62-625.420,62-640.100, 62-640.860, 62-660.803, 62-709.201, 62-709.320, 62-709.460, 62-709.510, 62-709.600, 62-710.201, 62-710.210, 62-710.401, 62-710.800, 62-711.300, 62-711.400, 62-711.500, 62-711.520, 62-711.530, 62-711.550, 62-711.801, 62-713.200, 62-713.220, 62-713.300, 400, 62-713.600, 62-780.150, 62-780.500, 62-780.600, and 62C-16.0051. Amendments to Chapter 62-701 will have an impact to Rule 62-709.300. Since the form for the compost rule asks for six copies of the application to be submitted and Rule 62-701.320 is being amended to only ask for one electronic copy, the compost rule will need to be amended to reflect this change.
