(1) Lakes or lake segments shall be included on the Planning List for nutrients if:
(a) The numeric interpretation of the narrative nutrient criterion established in subsection 62-302.531(2), F.A.C., is exceeded for any parameter;
(b) Algal mats or blooms are present in sufficient quantities to pose a nuisance or hinder reproduction of a threatened or endangered species, or
(c) There is a statistically significant increasing trend in the annual geometric means at the 95 percent confidence level in TN, TP, or chlorophyll a over the planning period using a Mann’s one-sided, upper-tail test for trend, as described in Nonparametric Statistical Methods by M. Hollander and D. Wolfe (1999 ed.), pages 376 and 724, which were incorporated by reference in Fl. Admin. Code R. 62-303.351
(d) There are insufficient data to calculate the long-term geometric mean for color, alkalinity or specific conductance for a lake, the lake shall be included on the Planning List if the annual geometric mean chlorophyll a value is greater than 20 ug/L in at least one year.
(2) Color, alkalinity, and specific conductance data used to establish the applicable lake criteria are subject to the data sufficiency requirements in sub-subFl. Admin. Code R. 62.302.531(2)(b)1.c.
