1(1) A Class I, I-Treated, II, III or III-Limited (if primary contact and recreational use is not limited) water shall be placed on the Planning List for evaluating primary contact and recreation use support based on bacteriological data if:
40(a) There is a sufficient number of samples from the water segment that do not meet the applicable water quality criteria for 62E. coli 64for predominantly freshwaters or enterococci for predominantly marine waters expressed as a Ten Percent Threshold Value (TPTV) based on the methodology described in subsection 8862-303.320(1), 89F.A.C. Data must meet the requirements of subsections and paragraphs 9962-303.320(2), 100(3), (4)(e)-(4)(g), (8), (9), F.A.C. Samples collected on different days will be assessed as individual samples and samples collected on the same day shall be averaged, or
127(b) 128The waterbody includes a sampling location that has one or more monthly geometric mean values above the monthly geometric mean 148E. coli 150criterion for predominantly freshwaters or enterococci criterion for predominantly marine waters during the planning period. To calculate a monthly geometric mean, there shall be at least ten samples collected within that month, with at least one sample from each full week of the month. 194Data must meet the requirements of 200subsections and paragraphs 20362-303.320(2), 204(3), (4)(e)-(4)(g), (8), (9), F.A.C., and samples collected on different days will be assessed as individual samples and samples collected on the same day shall be averaged.

274(a) The water segment includes a bathing area that was closed by a local health Department or county government for more than one week or more than once during a calendar year based on bacteriological data, or
311(b) The water segment includes a bathing area for which a local health Department or county government has issued closures, advisories, or warnings totaling 21 days or more during a calendar year based on bacteriological data, or
348(c) The water segment includes a bathing area that was closed or had advisories or warnings for more than 12 weeks during a calendar year by a local health Department or county government based on derived relationships between bacteria levels and rainfall or flow.
392(3) The Florida Department of Health (DOH) database shall be the primary source of data used for determining bathing area closures, advisories, and warnings.
416(4) Advisories, warnings, and closures based on red tides, rip tides, dangerous aquatic life, hurricanes, or short-term releases of pollutants, such as sewage spills, sewer line breaks, and medical wastes, shall not be included when assessing primary contact and recreation use support. However, the Department shall note for the record that closures, advisories, or warnings were excluded and explain why they were excluded.
