It is, by Tomasko's measures, healthy. FDEP agrees. The approach is to set standards to keep it that way. - Tomasko proposes standards based on "swath" of nutrient concentrations as a function of conductivity (salinity). [Values initially proposed for Florida estuaries by FDEP /EPA were TN 1.0 mg /L and TP 0.19 mg /L.] - The "swath" is drawn around data taken from Clam Bay in 2009 -2011. Clam Bay only. Not Estero Bay. Not Moorings Bay. - Upper and lower limits are desirable to guard against too much or too little dissolved nitrogen and dissolved phosphorus. - Compliance testing data are proposed to be taken from six sites once a month (Hoppensteadt). - If a number of values (Tomasko suggests more than 13 %) fall outside of the "swath," there may be a problem. - Testing would then be carried out (by the county ?) to see if water clarity (phytoplankton levels) and /or dissolved oxygen was affected. - Even if Clam Bay were to be declared "impaired," the current EPA proposal allows up to 15 years for remediation. This could be correction at point of pollution, i.e., back - tracking from point(s) where nutrients enter Clam Bay to find and correct source of pollution. It doesn't have to be dredging. - To that end, Tim Hall is currently measuring nutrient concentrations at 44 sites that empty into Clam Bay (Hoppensteadt). That will establish the basis for a point- source early - warning system. Timeline for setting nutrient standards for Florida estuaries 10/18/11 Deadline for public comments to FDEP 11/3/11 FDEP presents proposed standards to Environment Regulation Commission (ERC) 12/1/11 ERC adopts standards 2/12 FL legislature ratifies standards and FDEP submits to EPA 3/15/12 EPA proposes nutrient standards for estuaries and coastal waters 11/15/12 EPA finalizes standards, which will be implemented within 18 months, i.e., by 5/15/14. 0 0 o ^3^ i..i� tt � O O < .- a U O a • Total Nitrogen {mg /L} CD C) 6 cn ry 0 M o < 3 CD CD CD 0 z C rn ■ ( 0 CD0.
