These TMDLs address fecal coliform, low dissolved oxygen, and nutrient impairments in the Hillsborough River Basin. Specifically, the TMDL rules being proposed for adoption are fecal coliform TMDLs for Mill Creek and Trout Creek, dissolved oxygen and nutrient TMDLs for Baker Creek, Big Ditch, Channelized Stream, Mill Creek, Trout Creek, and Two Hole Branch, and dissolved oxygen TMDLs for Spartman Branch. These waterbodies were verified as impaired using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The methodology used to develop the fecal coliform TMDLs was the percent reduction method. The methodology used to develop the dissolved oxygen and nutrient TMDLs was either a combination of the Watershed Assessment Model (WAMView) and the Water Quality Analysis Simulation Program (WASP) or an empirical method. This rulemaking has been given OGC case number 09-0720.
