RULE NO: RULE TITLE
62-304.415: Lower St. Johns River Basin TMDLs
PURPOSE AND EFFECT: The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for fecal coliforms in the Lower St. Johns River Basin.
SUMMARY: This TMDL addresses fecal coliform impairments in the Lower St. Johns River Basin. Specifically, the TMDL rules being proposed for adoption are for Big Davis Creek, Big Fishweir Creek, Block House Creek, Deep Bottom Creek, Deer Creek, McCoy Creek, Miller Creek, New Castle Creek, Open Creek, Sherman Creek, Terrapin Creek, and Trout Creek (Fresh and Marine segments). These waterbodies were verified as impaired using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The methodologies used to develop the TMDLs were either the percent reduction or the load duration curve methods.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: No Statement of Estimated Regulatory Cost was prepared.
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.
