The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for certain waters impaired for nutrients in the Aucilla River Basin, Lower St. Johns River Basin, and Ocklawaha River Basin. Furthermore, in accordance with paragraph 62-302.531(2)(a), F.A.C., the nutrient TMDLs for Wacissa Springs, Crescent Lake, Lochloosa Lake, Cross Creek, and Lake Roberts will constitute site specific numeric interpretations of the narrative nutrient criterion set forth in paragraph 62-302.530(90)(b), F.A.C., that will supersede the otherwise applicable numeric nutrient criteria in subsection 62-302.531(2), F.A.C., for these surface water segments. The nitrate TMDL for the Wacissa River also will constitute a site specific numeric interpretation of the narrative nutrient criterion set forth in paragraph 62-302.530(90)(b), F.A.C., for this water segment that is in addition to the otherwise applicable numeric nutrient criteria in subsection 62-302.531(2), F.A.C., for the water segment.
