FINAL Study List Assessments in the Group 5 Basins

FINAL Study List Assessments in the Group 5 Basins

The department announces the availability of the FINAL Study List assessments for waterbodies and water segments within the Group 5 Basins: Everglades, Florida Keys, Indian River Lagoon, Perdido, Spring Coast, and Upper East Coast. The "Study List" is defined as the list of surface water or segments where additional information is needed, as identified in Rule 62-303.390, F.A.C.

The Study Lists include those waters that do not attain water quality standards and meet the following conditions:

A Class I, II, III or Class III-Limited water shall be placed on the Study List in assessment category 4d if:

  • A waterbody with a statistically-significant (at the 95 percent confidence level) increasing temporal trend in annual geometric means for TN, TP, nitrate-nitrite, or chlorophyll a and there is a reasonable expectation that the water will become impaired within 10 years.
  • A waterbody that does not achieve the Biological Health Assessment provisions in Rule 62-303.430, F.A.C., but a cause has not been identified.
  • A waterbody verified as not meeting the dissolved oxygen criterion pursuant to the verified list requirements, but a cause has not been identified.
  • For streams meeting the definition in subsection 62-302.200(36), F.A.C., that do not have a site specific numeric interpretation of the narrative nutrient criterion, the nutrient thresholds in subparagraph 62-302.531(2)(c)2., F.A.C., are exceeded based on data from the last 7.5 years and insufficient Biological Health Assessment, chlorophyll a, or other response variable data are available to fully assess achievement of the nutrient provisions in paragraph 62-302.531(2)(c), F.A.C.
  • There are fewer than twenty samples for a bacteriological water quality criterion, but there are five or more samples that do not meet an applicable water quality criterion based on data from at least five temporally independent sampling events;
  • A waterbody segment is verified as not meeting the bacteriological water quality criterion pursuant to Part IV of this Chapter, but the department determines that additional study is needed to evaluate whether the exceedances are due to natural sources given the predominance of natural land uses in the watershed or based on information submitted to the department; or
  • A waterbody exceeds a generally applicable criteria, but the department receives a petition for a SSAC pursuant to Rule 62-302.800, F.A.C., and additional time is needed to review and process the petition.

A Class I, II, III or Class III-Limited water shall be placed on the Study List in assessment category 4e if:

  • A waterbody where pollution control mechanisms are in place or planned that meet the requirements of subsections 62-303.600(1) and (3), F.A.C., except that there is uncertainty when water quality standards will be attained and the waterbody segment requires additional study;

Waterbodies placed into assessment category 4d will be targeted for strategic monitoring before the next cycle of assessments for that waterbody.  For waterbodies placed into assessment category 4e, the department shall evaluate progress towards attainment of water quality standards.  Please note that the department will submit waterbodies included on the FINAL Study List to EPA Region IV as water quality limited segments for inclusion on Florida’s 303(d) list in accordance with the Federal Clean Water Act.
