Next Steps
• SWS took this effort as far as we can in 2020 with existing budget• Update Long Range Financial Plan• Complete Business Case Evaluation of landfill/recycling/WTE options• Come back to assembly July/August with this information in hand to make
decision on continuing to investigate WTE, etc.• Submit FY2021 Budget for approval
