Federal Clean Water Act Monitoring and assessments completed statewide Standards not met? Section 303 (d) requires placing the water body on the “Impaired Waters List”

MN Clean Water Legacy Act Goals Identify all Impaired Waters Submit TMDLs to EPA on Time Comply with the Federal Clean Water Act Develop a Reasonable Time-Frame for Restoration Provide Technical and Financial Assistance Restore water quality and “De-list” Waters

Scope the project Conduct data inventory Identify water quality data gaps Identify watershed data gaps Determine whether new data is needed Develop data collection plans Collect new water quality data Analyze WQ data Define water quality problem Modeling Develop allocation formula Collect new watershed data TMDL formula TMDL process LA(s) + WLA(s) + Margin of Safety + Reserve Capacity = Total Maximum Daily Load LA = Load allocations from nonpoint sources WLA = Waste load allocations from point sources Margin of Safety = to account for potential scientific error Reserve capacity = set aside for future development

Public process Monitoring Plan Effectiveness to assess BMPs or other Validation of model or analytical assumptions Special concerns Implementation plan Projects, BMPs to pursue Notice to state register Public Hearing Study forwarded to EPA for approval Implementation TMDL study process continued

March 2008 – September 2008 Final Report –Closed out /posted –Reviewed/discussed feedback comments Turbidity Standard –Internal agency discussion on standard and value added work from comments –Turbidity standard triennial review North Shore comparative approach – assessing other streams, finding reference streams Input matters Water monitoring GIS and WEPP model Physical channel Completed BMPs

Poplar TMDL possible next steps Complete TMDL with data as is Enhance data and write TMDL Delay TMDL until turbidity standard evaluation/revision One of the first TMDLs for this region, sets a direction and stakeholder expectations for future work
