Update on BOD Sampling

1. Comp Sewer Plan estimated 15-20% of BOD f i d t i l di h

Update on BOD Sampling

BOD from industrial dischargersa. Significant Industrial Users (SIUs) are largest

fraction of industrial BODfraction of industrial BOD

2. 4 months of sampling conducted in 2010a 2 large SIU complexes sampled in spring and a. 2 large SIU complexes sampled in spring and

summer monthsb. Variable BOD load and solubilityyc. Squalicum complex is largest BOD sourced. Squalicum BOD averages 10-15% of BODe. Sampling results support initial BOD

estimates in Comp Sewer Plan

BOD Load ReductionBOD Load ReductionConclusions and Next Steps

1. SIU reduction and conservation may decrease 20-year BOD load by up to 17%a. Extends capacity provided by initial phase

by up to seven years

Cit E l d SIU ti 2. City, Ecology, and SIUs are supporting efforts to reduce BOD discharges

dd l l d3. Additional sampling and monitoring in 2011 will document progress
