The Department of Environmental Protection (department) is initiating rulemaking to consider proposed revisions to the human health-based surface water quality criteria in Chapter 62-302, F.A. C., that 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-B, Treated Potable Water Supplies) and to reclassify seven surface waters into the new sub-classification.
