Future Objectives & Involvement Opportunities

Future Project Objectives

Task C. Review and Analyze Existing Data Task D. Conduct Additional Monitoring and Gather Information Task E. Identify Pollutant Sources and Conduct Modeling Efforts Task F. Develop a Draft and a Final TMDL Report Task G. Produce an Implementation Plan

Future Project Opportunities for Stakeholders

Assist in filling data gaps and the identification of “Hot Spots” & Sources
Assist in conducting additional monitoring and data gathering
Participation in future Stakeholder Meetings (every 4-6 months)
Meetings would be held after the completion of a milestone task.

Best Management Practices: Bacteria Removal

Potential sources

Septic systems Livestock operations Stormwater (sources vary)

Potential solutions

Enforce compliance for failing septic systems Reduce feedlot/pasture runoff in priority areas (fencing, buffers) Filter stormwater (rain gardens, infiltration basins), reduce sediment (street sweeping)

SLIDE 15

Minnesota Pollution Control Agency

Best Management Practices: Bacteria Removal

Potential sources

Wildlife and pet populations Wastewater treatment facilities Manure spreading & storage

Potential solutions

Evaluate pet waste & wildlife feeding ordinances, create educational materials Identify illicit sewer connections Reduce bacteria from land application of manure (stream/ditch buffers, immediate incorporation, conservation tillage, lined structures)

SLIDE 16

TMDL Process

Determine Sources Causing Impairment Analyze existing data Conduct additional monitoring Allocate Pollutant Loads Use models/other tools - ID stresses/develop loads Assign loads – permitted/non-permitted sources *Deliverable: TMDL Report Develop Implementation Strategies/Plan Identify leads & partners Create monitoring and evaluation plan *Deliverable: Implementation Plan

SLIDE 17

Minnesota Pollution Control Agency LA(s) + WLA(s) + Margin of Safety + Reserve Capacity = Total Maximum Daily Load

A TMDL Study must complete this pollution load allocation formula:

Where: LA = Load allocations from nonpoint sources “non-permitted sources” WLA = Waste load allocations from point sources “permitted sources” Margin of Safety = to account for potential scientific error “uncertainties” Reserve capacity = set aside for future development

Quantifying a TMDL Number

Sum of the allowable loads of a single pollutant from all contributing permitted and non-permitted sources

SLIDE 18

Minnesota Pollution Control Agency

What do TMDL Projects mean for Stakeholders?

Increased funding

pportunities for

implementation activities & improved WQ Increased understanding

f links between water

quality monitoring data and potential pollutant sources Better partnerships
