A stream or stream segment shall be included on the Planning List for nutrients if:
(1) The applicable numeric interpretation of the narrative nutrient criterion established in subsection 62-302.531(2), F.A.C., is exceeded for any parameter;
(2) For streams meeting the definition in subsection 62-302.200(36), F.A.C., that do not have a site specific numeric interpretation of the narrative nutrient criterion, the nutrient thresholds in subFl. Admin. Code R. 62-302.531(2)(c)2., are exceeded and insufficient Biological Health Assessment data are available to fully assess achievement of the nutrient provisions in subFl. Admin. Code R. 62-302.531(2)(c)1.;
(3) Algal mats or blooms are present in sufficient quantities to pose a nuisance or hinder reproduction of a threatened or endangered species;
(4) An annual geometric mean chlorophyll a is greater than 20 ug/l, or
(5) 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 are incorporated by reference herein.
