  • Magnitude of $ that is needed ->where is the best place to spend
  • Is the objective to improve what quality or
  • What is the GOAL?
  • Focus on the task – make a choice + lets go
  • 10% reduction is pretty good
  • Stop dumping – embarrassment

  • Issue of economic benefit is a factor worth considering
  • Spending all the $ won't improve water quality
  • Vs load (phosphorus is huge)
  • Are we reducing CSOs or water quality
  • of CSOs is useless – can be 1 hr, 1 day, 1 week -> quantity overflow
  • 22 overflows x 79? They don't all discharge @ the same time.

  • What is the real benefit to basement flooding (now + later) – what change for investment?
  • Budget process – with structural deficit, need transparent process
  • Public education on human health impacts
    • Safety precautions
    • Awareness when events are happening (so rec users can make informed decisions)
    • Same goes for treatment plant discharges
  • Incentive e.g. in Seine River area
