WBID 2205B was incorrectly assigned to Cedar River stations intended to be assessed on 1998 303(d) List; stations are actually located within WBID 2213P. To correct this, WBID 2213P will be split into 2213P1 Ortega River and 2213P2 Cedar River, to which the Cedar River stations will be assigned. WBID 2205B is being delisted from the 1998 303(d) List for all parameters on that list based on

### Florida's waterbody classifications are defined as: 1 - Potable water supplies 2 - Shellfish propagation or harvesting 3F - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in fresh water 3M - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in marine water 4 - Agricultural water supplies 5 - Navigation, utility, and industrial use

### n is equal to the number of samples. When samples are collected at the same location less than 4 days apart, the median of those results represents a single sample for the purpose of determining n.

### The Cycle 1 assessment was done in 2003 and included data from that Verified Period (January 1, 1996 through June 30, 2003).

4

### The Cycle 2 assessment is the current assessment and includes data from the Verified Period (January 1, 2001 through June 30, 2008). †

### EPA's Integrated Report Category: 1 - Attains all designated uses 2 - Attains some designated uses and insufficient or no information or data are present to determine if remaining uses are attained 3A - No data and information are present to determine if any designated use is attained 3B - Some data and informationare present but not enough to determine if any designated use is attained 3C - Enough data and information are present to determine that one or more designated uses may not be attained according to the Planning List methodology 4A - Impaired for one or more designated uses but does not require TMDL development because a TMDL has already been completed. 4B - Impaired for one or more designated uses but does not require TMDL development because the water will attain water quality standards due to existing or porposed measures. 4C - Impaired for one or more criteria or designated uses but does not require TMDL development because impairment is not caused by a pollutant. 4D - The waterbody does not meet applicable criteria, but no pollutant can be identified; therefore a TMDL will not be developed at this time. 4E - Impaired, but recently completed or on-going restoration activites are underway to restore the designated uses of the waterbody. 5 - Water quality standards are not attained and a TMDL is required.Lower St. Johns Basin Group 2 Cycle 2 - Verified List

### Where a parameter was identified as impaired, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or human health, which have been assigned a “high” priority, and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based on the following: it is our intent that listings with a "High" priority be addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow, and listings with a "Low" priority be addressed within the next 10 years.

### A statewide TMDL for mercury, that will address this waterbody, is scheduled to be completed in 2012. ^ Beach advisories are based on FL Dept of Health Enterococcus (>103 CFU/100mL) or fecal coliform (>399 CFU/100mL) criteria. N/A = Not Applicable

Beach advisory data is based on "DOH_beach_stations" file created 10/06/2008 by Barbara Donner of FDEP. Fish advisory data is based on "2008_fish_advisories_by_WBID" file created 12/12/2008 by Barbara Donner of FDEP. The Group 2 Lower St. Johns Master list is based on IWR Run 35_2.
