The target nutrient concentration used in the subsequent TMDL will be determined during the TMDL process.3Priorities and schedule for TMDL development are only provided for waters in Category 5. Priorities set under the EPA Consent Decree were retained. Medium priority is used for newly listed waters identified under the IWR.4PP - Planning Period (January 1, 1992 through December 31, 2002); VP - Verified Period (January 1, 1998 through June 30, 2005)The Fisheating Creek Verified List is based on IWR Run 22.February 15, 20062 of 2 Florida Department of Environmental Protection
