Fla. Admin. Code Ann. R. 62-303.352 - Nutrients in Freshwater Lakes

(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 Rule 62-303.351, F.A.C.

(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-subparagraph 62.302.531(2)(b)1.c., F.A.C.
