Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.410

Santa Fe River Basin TMDLs

PURPOSE:

The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for nutrients and dissolved oxygen in the Santa Fe River (below river rise) and to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for fecal coliforms (New River), total nitrogen (New River WBIDs 3506 and 3506B), and total phosphorus (New River WBID 3506).

SUMMARY:

The Santa Fe TMDL addresses nutrients and dissolved oxygen impairments in the Santa Fe River (below river rise). This waterbody was verified as impaired by nitrate-N and dissolved oxygen (DO) using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. For DO, the nutrient TMDL target, set as a monthly average for nitrate-N, will reduce any pollutant impacts associated with DO. A concentration target was used to develop the nutrient TMDL. The New River TMDLs address fecal coliform and DO impairments in the New River. This waterbody was also verified as impaired by fecal coliforms and dissolved oxygen using the methodology established in Chapter 62-303, F.A.C. For the DO TMDLs, water quality targets were identified for total nitrogen and/or total phosphorus using a bioregion reference nutrient approach. The Kansas approach was used to develop the fecal coliform TMDL.
