    1045(c) If one or more zone(s) at an application site changes ownership or becomes part of a different application site, the cumulative loading determination for the affected zone(s) shall account for the prior applications of biosolids.

    1081(d) If biosolids that are subject to the cumulative loading limitations of subsection 109462-640.700(7), 1095F.A.C., have been applied to an application zone, and the cumulative loading amount of one or more pollutants is not known, no further applications of biosolids shall be made to that application zone. To continue use of the zone, the permittee shall establish cumulative loadings below the application limits in paragraph 114662-640.700(7)(b), 1147F.A.C., by calculation methods and analysis or by conducting soil testing in accordance with subparagraph 116262-640.650(3)(b)2., 1163F.A.C.

    1164(8) Setback Distances.

    1167(a) The following setback distances shall apply to land application sites that accept either Class A or Class B biosolids.

    11871. The biosolids land application zone shall not be located closer than 1000 feet to any Class I water body, Outstanding Florida Water or Outstanding National Resource Water, or 200 feet from any other surface water of the state as defined in Section 1230403.031, F.S. 1232This setback does not apply to waters owned entirely by one person other than the state, nor to canals or bodies of water used for irrigation or drainage, which are located completely within the application site and will not discharge from the application site. The setback area shall be vegetated. The 200 foot setback distance from surface waters shall be reduced to 100 feet if the biosolids are injected or incorporated into the soil.

    13062. The biosolids land application zone shall not be located closer than 300 feet from any private drinking water supply well or 500 feet from any public drinking water supply well.

    13373. The land application zone and an area 200 feet wide adjacent to the application zone shall contain no visible evidence of subsurface fractures, solution cavities, sink holes, excavation core holes, abandoned wells or any other natural or man-made conduits that could allow direct contamination of ground water.

    13854. Biosolids shall not be stored or stockpiled at a land application site within 1320 feet of a building occupied by the general public. This distance shall be decreased to the setback distance provided by subparagraph 142162-640.700(8)(b)1., 1422F.A.C., if the owner of the building provides written consent.

    1432(b) The following additional setback distances shall apply to land application sites that accept Class B biosolids.

    14491. Class B biosolids shall not be applied within 300 feet of a building occupied by the general public. This distance shall be reduced to 100 feet if biosolids  are injected into the soil or if written permission is obtained from the building owner.

    14932. Class B biosolids shall not be applied within 75 feet from property lines, unless applied to the medians or roadway shoulders of restricted public access roads.

    1520(9) The pH of the biosolids soil mixture shall be 5.0 or greater at the time Class A or Class B biosolids are applied. At a minimum, soil pH testing shall be done annually.

    1554(10) A minimum unsaturated soil depth of two feet is required between the depth of biosolids placement and the water table level at the time the Class A or Class B biosolids are applied to the soil. The permittee can indicate the seasonal high ground water level for the application site in the Biosolids Site Permit Application, Form 161262-640.210(2)(d), 1613by use of soil survey maps. If the seasonal high ground water level is within two feet of the depth of biosolids placement or cannot be determined at the time of permitting, the water table level shall be determined in one or more representative location(s) in the application zone before each application of biosolids, by measuring the water level in a water-table monitoring well or a piezometer.

    1680(11) Runoff Prevention Requirements.

    1684(a) Biosolids shall not be applied at an application zone during rain events that cause ponding or sheet flow, when ponding exists, or when surface soils are saturated.

    1712(b) Topographic grades of the land application zone must be eight percent or less. If application site slopes exceed three percent in one or more application zones, biosolids shall be injected or incorporated, or documentation shall be provided with the NMP demonstrating that suitable soil infiltration rates and stormwater control measures exist at the application site to retain runoff generated by a 10-year recurrence interval 1-hour duration storm event. Berms shall be placed for this purpose if necessary.

    1790(c) Biosolids shall not be land applied on soils having a flooding frequency class of “frequent” or “very frequent”, or on soils having a flooding duration class of “long” or “very long”, as given in soil surveys and as defined by the NRCS in Section 1835618.27 1836of the 1838National Soil Survey Handbook, 1842as of October 2009, hereby adopted and incorporated by reference and available from the Department of Environmental Protection, Domestic Wastewater Section, M.S. 3540, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400 or any of the Department’s District Offices.
