Overview

62-303.370	Fish and Shellfish Consumption Use Support

PURPOSE:

The department is amending Chapter 62-303, F.A.C., to update the listing methodology for assessing human health-based water quality criteria as part of the process to identify impaired surface waterbodies.  This rulemaking is being conducted in conjunction with rulemaking to revise the human health-based criteria in Chapter 62-302, F.A.C. (noticed under a separate rulemaking notice).  The proposed revisions to Chapter 62-303, F.A.C., are designed to revise the assessment methodology to be consistent with the proposed change in the expression of the human health-based water quality criteria for non-carcinogens from single sample maximums to annual averages (proposed concurrently as changes to Chapter 62-302, F.A.C.) and to add a minimum sample size for the calculation of an annual average.  Additionally, in accordance with the requirements of paragraph 403.061(29)(b) and paragraphs 403.861(21)(a) and (b), Florida Statutes, enacted under Chapter 2016-01, Laws of Florida, the department is proposing to establish a new sub-classification of surface waters (Class I-Treated, Treated Potable Water Supplies), which will require minor revisions in Chapter 62-303, F.A.C.  Specifically, the department plans to revise a number of rules in Chapter 62-303, F.A.C., to clarify that Class I waters include both “Class I” (existing Class I waters) and “Class I-Treated” (Treated Potable Water Supply waters).

SUMMARY:

The department is proposing to update the listing methodology for assessing human health-based water quality criteria in Chapter 62-303, F.A.C., as part of the process to identify impaired surface waterbodies.  The department is also amending Chapter 62-303, F.A.C., to revise the methodology for identifying impaired surface waters to provide for the assessment of a new sub-classification of waters for Treated Potable Water Supplies (Class I-Treated).  The Department conducted public workshops on May 10, 11, and 12, 2016, in Stuart, Orlando, and Tallahassee, respectively.
