RULE NO: RULE TITLE
62-304.600: Tampa Bay Basin TMDLs
PURPOSE AND EFFECT: The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs) and their allocations for waters in the Tampa Bay Basin that are impaired for fecal coliform.
SUMMARY: These TMDLs address fecal coliform impairments in the Tampa Bay Basin. Specifically, the TMDL rules being proposed for adoption are for Allen Creek (tidal), Alligator Creek, Bellows Lake Outlet, Bishop Creek (freshwater and tidal segments), Brushy Creek, Bullfrog Creek (freshwater and tidal segments), Cross Canal (North), Double Branch, Little Bullfrog Creek, Lower Rocky Creek, Moccasin Creek (tidal), Mullet Creek (freshwater and tidal segments), Rocky Creek, and Sweetwater Creek. 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 load duration analysis method. These TMDLs were originally published in August 2009; however, because certain other TMDLs also proposed for Rule 62-304.600, F.A.C., are the subject of an administrative challenge, the Department must republish these TMDLs so that they may proceed separately for adoption. This rulemaking has been given OGC case number 10-1477.
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.
SPECIFIC AUTHORITY: 403.061, 403.067 FS.
LAW IMPLEMENTED: 403.061, 403.062, 403.067 FS.
