Phosphorus in the Fox-‐Wolf Basin
• Urban, ag, industrial sources causing impairments
• Heavy phosphorus loading causing hypoxic “dead zone”
• Upper Fox and Wolf will also need work

Wisconsin’s Phosphorus Rule • Passed in 2010 – first of its kind in naBon • Statewide numeric standards • Package of changes to state Natural Resource code
– NR 102: Sets P limits for state waters – NR 151: Agricultural performance standards to reduce runoff
– NR 217: Water-‐quality based effluent limits (WQBELs) and compliance opSons for meeBng phosphorus standards

Adaptive Management Option • A strategy for WPDES permi0ees to comply with phosphorus standards by reducing NPS
• Cost-‐effecBve and comprehensive
• Focus = Watershed-‐wide collaboraBon

AMO Criteria • Exceedance of phosphorus in permi0ee’s receiving water caused by both PS and NPS
• Exceedance is primarily due to NPS • At least 50% of total phosphorus OR effluent limit demonstrably can’t
be a0ained without reducing NPS • MS4s count as NPS
• WQBEL is stringent • FiltraBon or an equivalent technology would be necessary to meet
limit • Generally considered 0.4 mg/L or lower

Must include: • Analysis of major P sources in the watershed • Goals and measures for assessing progress and compliance
• IdenBficaBon of partners & their level of support • Demonstrated ability to fund the project **9 elements required for a complete plan to DNR

Case Study: Lower Fox AMO
• Central point source: NEW Water (Green Bay Metropolitan Sewerage District)
• Projected cost of ~$223 million to meet 0.2 mg/L TMDL limit
More cost-‐effecBve to reduce NPS
