The Department is amending Rule 62-302.532, F.A.C., to establish NNC for total nitrogen, total phosphorus, and chlorophyll a in individual estuary segments for the following estuaries: Loxahatchee River, Lake Worth Lagoon, Halifax River, Guana River/Tolomato River/Matanzas River (GTM), Nassau River, Suwannee River, Waccasassa River, Withlacoochee River, and Springs Coast (Crystal River to Anclote River). In addition, remote sensed NNC for chlorophyll a are established for coastal offshore waters where chlorophyll a criteria have not been adopted.
