2 According to Rule 62-303.720,<br />

F.A.C., this segment <strong>of</strong> the river can<br />

be delisted because there were<br />

three consecutive TSI annual<br />

means below 60 in 1998-2000. Colimitation<br />

by nitrogen and<br />

phosphorus based on a TN/TP<br />

median <strong>of</strong> 19 (204 values) during<br />

the PP and a median <strong>of</strong> 20 (208<br />

values) during the VP. PP - 1 TSI<br />

annual mean exceed threshold. VP<br />

- 1 TSI annual mean exceed<br />

threshold. 195 TN values, median<br />

0.74 mg/L. 194 TP values, median<br />

0.04 mg/L.<br />
