3. Total Maximum Daily Load Total Maximum Daily Load Main Concepts of a TMDL: Main Concepts of a TMDL: TMDL: Maximum amount of pollutant that can be received by a water body and still meet standards. TMDL: Maximum amount of pollutant that can be received by a water body and still meet standards. TMDL Allocates loads among sources and geographic areas. TMDL Allocates loads among sources and geographic areas. TMDL = WLA + LA + MOS TMDL = WLA + LA + MOS –WLA: Sources with Permits (point sources) –LA: Sources without Permits (nonpoint sources) –MOS: Margin of Safety, protective of environment. TMDL is usually determined by a scientific study of the water body, often using computer models. TMDL is usually determined by a scientific study of the water body, often using computer models.

4. Watershed Implementation Plans Three-Phased Planning Process: Three-Phased Planning Process: Phase I Plans - 2010 Phase I Plans - 2010 –Nutrient and sediment target loads by sector and impaired segment –Statewide strategies for reducing loads in each source sector –Starting Point for Phase II Plans Phase II Plans – 2011/12 Phase II Plans – 2011/12 –Refined EPA Watershed Model Results –Divide loads by smaller geographic areas –More detailed strategy to meet 2017 Interim Target - 70% reduction –2-Year Milestone actions for 2012-2013 Phase III Plans – 2017 Phase III Plans – 2017 –Modification of TMDL and allocations, if necessary Identify changes needed to meet Final Target loads Identify changes needed to meet Final Target loads
