Numeric Nutrient Criteria (NNC) - Coastal Nutrient Regions

Criteria for chlorophyll a for the open ocean coastal waters listed in subsection 62-302.532(2), F.A.C., are delineated by Coastal Segments. The Coastal Segments were adopted by reference in subsection 62-302.532(2), F.A.C., in the Map of Florida Coastal Segments, dated May 13, 2013 (http://www.flrules.org/Gateway/reference.asp?No=Ref-03017). The open ocean coastal chlorophyll a criteria were derived from satellite remote sensing techniques and are expressed as annual Geometric Mean remotely sensed chlorophyll a values. These criteria were calculated excluding Karenia brevis blooms (>50,000 cells/L). The annual geometric mean criteria are based on measurements using the SeaWiFS satellite or standardized MODIS or MERIS satellite data. The standardization factors for MODIS and MERIS are provided in subsection 62-302.532(2), F.A.C. Achievement of these criteria shall be assessed only by using satellite remote sensing data that are processed in a manner consistent with the derivation of the criteria. Data selection and preparation shall be consistent with the process described in Section 1.4.3 and Section 1.4.4, pages 14 through 17, in the report titled “Technical Support Document for U.S. EPA’s Proposed Rule for Numeric Nutrient Criteria for Florida’s Estuaries, Coastal Waters, and South Florida Inland Flowing Waters, Volume 2: Coastal Waters,” U.S. Environmental Protection Agency, November 30, 2012 (http://www.flrules.org/Gateway/reference.asp?No=Ref-03018).
