- Timeline 2006 to 2025 $2 billion dollars 28 miles – 250 feet deep – 18 feet diameter Treatment plant expansions to 550 MGD (from 300 MGD) Capture 99% of CSO volumes (~2 events per year, Originally about 6 BG)

- Regulatory: Number of years until regulatory requirement is expected Infrastructure: Useful remaining life Operations & Tech: Number of years until payback (how much does it help out ops) Enviro, Safety & Security: Likelihood/impact of safety concern Capacity & Growth: Number of years until capacity is needed Failure Probability: Likelihood of an issue occurring Failure consequence: The ultimate consequence if the failure occurs Discretionary: To be added at the discretion of Operations and Engineering (must include a justification)
