Section 62-660.806 - General Permit for Disposal of Fresh Citrus Fruit Wash Water(1) General Requirements, Conditions and Applicability.(a) This rule authorizes a general permit for any person constructing or operating a wastewater treatment and sprayfield land application effluent disposal system for wash water from fresh citrus fruit packinghouses as defined in paragraph 62-660.806(2)(c), F.A.C. This general permit applies to facilities that generate more than 5, 000 gallons per day of wash water during the operating season, provided that all of the conditions of this rule are met. Ground water monitoring shall not be required for facilities covered under this rule.(b) Any facility generating less than 5, 000 gallons per day during the operating season is exempt from the requirement to obtain this General Permit or a Department industrial wastewater permit if all of the following requirements are met:1. Wastewater is not discharged directly to surface waters or to ground waters through wells or sinkholes that allow direct contact with Class G-I, F-1 or G-II ground waters as defined in Chapter 62-520, F.A.C.,2. The disposal of the facility's wastewater does not cause or contribute to a violation of surface water and/or ground water quality standards,3. There is a 100-foot setback between the wetted perimeter and the facility's property boundary,4. Best Management Practices (BMPs) are implemented to minimize ponding or runoff from the land application site and ensure proper maintenance of the sprayfield,5. Records are maintained in accordance with subsection 62-660.806(6), F.A.C.(c) This general permit is not applicable to fresh citrus packinghouses engaged in other auxiliary operations such as citrus juicing that commingle their waste streams with wash water. Facilities that utilize percolation ponds, other types of land application disposal, or a sprayfield type of land application not otherwise complying with the requirements of this rule, are not covered by this general permit. These facilities shall:1. Obtain an individual wastewater permit in compliance with Chapter 62-620, F.A.C.,2. Obtain a "Generic Permit for Discharges from Fresh Citrus Fruit Packinghouses to Percolation Ponds" in accordance with subsection 62-621.500(1), F.A.C.,3. Meet the provisions of paragraph 62-660.806(1)(b), F.A.C., or4. Obtain an exemption from permitting pursuant to Rule 62-4.040, F.A.C.(d) Facilities that discharge to a Department approved domestic wastewater collection system are not required to obtain an industrial wastewater permit and are not subject to the requirements of this rule. Refer to Chapter 62-604, F.A.C., Collection Systems and Transmission Facilities, for the need to obtain a permit under that chapter.(e) This general permit does not relieve the permittee of the responsibility for obtaining any other permits required by the Department or any federal, state, local agency, or authority.(f) This general permit shall be subject to the general conditions of Rule 62-4.540, F.A.C.(g) The permittee shall complete and submit DEP Form 62-660.806(1)(g), Notification Form To Use General Permit For Land Application of Fresh Citrus Packinghouse Wash Water Effluent, effective May 10, 2005, which is adopted and incorporated herein by reference, and the information required by that form 30 days before use of this general permit.

These deviations and the reasons for them shall be described in detail.(2) Definitions. Terms used in this rule shall have the meaning specified below: (a) "Cull fruit" means citrus fruit that is removed from the packaging process because of damage or other reasons that make the citrus fruit unsuitable for packaging.(b) "Existing fresh citrus fruit packinghouse" or "existing facility" means a packinghouse which was in operation on or before May 10, 2005.(c) "Fresh citrus fruit packinghouse" or "facility" means a facility whose primary purpose is to wash, disinfect, sort, and package fresh citrus fruit and is assigned Standard Industrial Classification (SIC) Code 0723.(d) "Land application site" means an area of land used for treatment and disposal of wash water and solids.(e) "New fresh citrus fruit packinghouse" or "new facility" means a packinghouse which was constructed or placed into operation after May 10, 2005, or to an existing facility to which a substantial modification was made after May 10, 2005.(f) "Operating season" is the period of operation for citrus packinghouse facilities.(g) "Percolation pond" means an impoundment, either above or below the natural land surface that is designed to percolate wash water.(h) "Private drinking water supply well" means a well serving private or multifamily water systems as defined in Rule 62-532.200, F.A.C.(i) "Public drinking water supply well" means a well serving a public water system as defined in Rule 62-550.200, F.A.C.(j) "Solids" means leaves, twigs and other objects.(k) "Sprayfield" means a land application site where spray irrigation of a grass cover crop or a citrus grove is utilized for treatment and disposal of wash water at predetermined application rates necessary to prevent degradation of surface water and groundwater.(l) "Wash water" means the water used to wash, disinfect, and apply a protective wax to fresh citrus fruit before packaging.(3) Prohibitions. (a) Discharge from any land application site to surface waters of the state is not authorized by this permit.(b) Discharge from any land application site shall not cause or contribute to a violation of surface water and/or ground water quality standards.(c) No discharge of wastes or wastewater other than wash water generated by the operations defined as fresh citrus fruit packinghouses in paragraph 62-660.806(2)(c), F.A.C., shall be disposed of in sprayfields authorized by this permit. This prohibition includes, but is not limited to, stormwater, sanitary wastewater generated by employees of the facility, wastewater generated by washing or maintaining mobile equipment, or wastewater generated by ancillary operations.(4) Solids Management. (a) The permittee shall dispose of solids from the screening or sedimentation system with cull fruit in an approved landfill or solid waste facility. Alternatively, the permittee may apply solids to a land application site in accordance with subsection 62-660.806(5), F.A.C., below.(b) Culled fruit shall be managed in such a manner that no contact stormwater shall be produced or discharged to the disposal system or waters of the State.(5) Design and Operation Requirements.
