BURLINGTON’S INTEGRATED WATER QUALITY PLAN Jenna Olson Water Policy & Programs Manager Burlington DPW – Water Resources Division

**Each area of responsibility involves its own set of regulatory requirements

• • • • • • • • •

Required Phosphorous Reduction (pounds / year) 25000 20000 15000 10000 5000 0 Current Annual Load Required Reduction Current Annual Load = 20,523 pounds / year Required Reduction = 12,958 pounds / year

• There are many different pathways to compliance with the phosphorous reduction requirement • A combination of projects that will meet the phosphorous reduction requirement – a “Project Portfolio” – must be chosen • Each ”Project Portfolio” has different impacts, costs, and benefits • Many potential projects involve neighborhood construction, impacts on parking, or changes in how leaves, lawns, or yards are managed

BUILDING A PROJECT PORTFOLIO

Wastewater Treatment Plants • Further optimize P removal processes • Add tertiary or dual-use processes Combined Sewer System Improvements • Sewer separation • Distributed storage Stormwater Management • Install more distributed GSI systems Non-Structural Programs • Expand street sweeping practices • Expand leaf management options Private Property • Offer rebates / grants for GSI installations • Update / enhance ordinances

Example: • Neighborhood green infrastructure vs. combined sewer controls Example: • Resources needed for street sweeping

• Wastewater & Combined Sewers – greater certainty, but more cost & no neighborhood greening benefit • Green stormwater infrastructure – preferred in some neighborhoods, less regulatory certainty & changes to streets • Operations - Street sweeping, catch basin cleaning, rebates, incentives – less certainty, involve individual behavior changes, but other ancillary benefits • Grants/rebates : Provide more funds for property owners to take beneficial steps? • Regulations are more effective than incentives, but impose cost • Leaf control has big impacts on phosphorous loading – but may require different regulations and actions • Street sweeping improves bikeability and protects the lake – but requires more intensive parking management

NEXT STEPS JULY • Public input summaries • Presentations to DPW Commission & TEUC • NPA Outreach AUGUST • Public meetings to weigh in on specific portfolio options SEPTEMBER • Presentations / hearings on preferred portfolio OCTOBER – NOVEMBER • Finalizing Integrated Plan with regulators DECEMBER • Complete Integrated Plan
