4. Recommendations & Research Needs Lake-wide protection act and associated plan –All the PPLs and agricultural sources Offsetting/trading program –What would the effectiveness be? Quantify phosphorus loadings –Identity priority areas and implement policy Funding body for ageing infrastructure –Target priority areas and most significant sources Identify emerging sources of phosphorous –What emerging industries will contribute new sources of phosphorous to Lake Erie?
