PURPOSE AND EFFECT: The proposed revisions to the human health-based surface water quality criteria in Chapter 62-302, F.A. C., are designed to ensure that Floridians can safely eat Florida fish and drink local tap water.  The revisions are based on updated scientific information, including more recent fish and drinking water consumption rate information, updated toxicological information, and revised methods to estimate bioaccumulation of pollutants in fish.  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) and to reclassify seven surface waters into the new sub-classification.

SUMMARY: The department is proposing the revision of human health-based surface water quality criteria within Chapter 62-302, F.A.C.  The department is also proposing to establish a new sub-classification of surface waters (Class I-Treated, Treated Potable Water Supplies) within Chapter 62-302, F.A.C., with reclassification of seven surface waters from Class III waters to Class I-Treated. The Department conducted public workshops on May 10, May 11, and May 12, 2016, in Stuart, Orlando, and Tallahassee, respectively.

SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS AND LEGISLATIVE RATIFICATION:  The Agency has determined that this will have an adverse impact on small business or likely increase directly or indirectly regulatory costs in excess of $200,000 in the aggregate within one year after the implementation of the rule. A SERC has been prepared by the Agency. 

The Agency has determined that the proposed rule is not expected to require legislative ratification based on the statement of estimated regulatory costs or if no SERC is required, the information expressly relied upon and described herein: Based on the SERC analysis and companion cost estimate developed for Rule 62-302.530, F.A.C., anticipated costs associated with adoption of the revised human health-based criteria were estimated to be $ 5,238. This is an estimated cost to the department to collect additional data to determine whether or not four waterbody identification units (WBIDs) should be placed on the Impaired Waters Rule (Chapter 62-303, F.A.C.) Verified List as impaired for two of the proposed human health-based criteria. Based on the SERC analysis and companion cost estimate developed for Rule 62-302.400, F.A.C., the department has concluded that there will be no costs associated with the reclassification of seven waterbodies (or portions thereof) to the newly created Class I-Treated classification.  The Department relied upon the SERCs to determine whether legislative ratification would be required.  Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

62-302.530 Table: Surface Water Quality Criteria.

The following table contains both numeric and narrative surface water quality criteria to be applied except within zones of mixing. The left-hand column of the Table is a list of constituents for which a surface water criterion exists. The headings for the water quality classifications are found at the top of the Table, and the classification descriptions for the headings are specified in subsection 62-302.400(1), F.A.C. Applicable criteria lie within the Table. The individual criteria should be read in conjunction with other provisions in water quality standards, including Rule 62-302.500, F.A.C. The criteria contained in Rule 62-302.500, F.A.C., also apply to all waters unless alternative or more stringent criteria are specified in Rule 62-302.530, F.A.C. Unless otherwise stated, all criteria express the maximum not to be exceeded at any time except within established mixing zones or in accordance with site-specific effluent limitations developed pursuant to Rule 62-620.620, F.A.C. In some cases, there are separate or additional limits, which apply independently of the maximum not to be exceeded at any time. For example, the human health-based criteria that for carcinogens, which are expressed as an annual average (denoted as “annual avg.” in the Table), are applied as the maximum allowable annual average concentration at the long-term harmonic mean flow (see subsection 62-302.200(2), F.A.C.). Numeric interpretations of the narrative nutrient criterion in paragraph 62-302.530(47)(b), F.A.C., shall be expressed as spatial averages and applied over a spatial area consistent with their derivation. In applying the water quality standards, the Department shall take into account the variability occurring in nature and shall recognize the statistical variability inherent in sampling and testing procedures. The Department’s assessment methodology, set forth in Chapter 62-303, F.A.C., accounts for such natural and statistical variability when used to assess ambient waters pursuant to sections 305(b) and 303(d) of the Federal Clean Water Act.

Notes: (1) “ln H” means the natural logarithm of total hardness expressed as milligrams/L of CaCO3. For metals criteria involving equations with hardness, the hardness shall be set at 25 mg/L if actual hardness is < 25 mg/L and set at 400 mg/L if actual hardness is > 400 mg/L. (2) This criterion is protective of human health not of aquatic life. (3) For application of dissolved metals criteria see paragraph 62-302.500(2)(d), F.A.C. (4) Class III-Limited waters have at least one Site Specific Alternative Criterion as established under Rule 62-302.800, F.A.C.
