Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.645

Springs Coast Basin TMDLs

PURPOSE:

The purpose of the rule is to adopt total nitrogen and carbonaceous biochemical oxygen demand (CBOD) Total Maximum Daily Loads (TMDLs), and their allocations, for the Stevenson Creek Tidal Segment in the Springs Coast Basin.  Furthermore, upon paragraph 62-302.531(2)(a), F.A.C., becoming effective, the total nitrogen TMDL for this segment will constitute a site specific numeric interpretation of the narrative nutrient criterion set forth in paragraph 62-302.530(47)(b), F.A.C. that will supersede the otherwise applicable numeric nutrient criteria in paragraph 62-302.531(2)(c) for this particular surface water segment.  The CBOD TMDL is not included as part of this site specific numeric nutrient interpretation.

SUMMARY:

The TMDL address certain dissolved oxygen and nutrient impairments in the Stevenson Creek Tidal Segment in the Springs Coast Basin.  The waterbody was verified as impaired for dissolved oxygen and nutrients using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The methodologies used to develop the TMDLs were applications of a mechanistic watershed model and surface water model.  This rulemaking has been given an OGC case number 08-2478.
