✅ What is public about the CSO / interceptor plan?!?

• The City of Anderson is subject to an enforceable consent-decree with U.S. Environmental Protection Agency (EPA) regarding CSOs.

​

• As part of that, the city developed a “Long Term Control Plan” (LTCP) to reduce or eliminate overflows through infrastructure upgrades. Commonwealth Engineers+2City of Anderson+2
   

• According to a recent document from the state (Indiana Department of Environmental Management, IDEM), the currently approved LTCP alternative involves:
   

  • Construction of a parallel interceptor sewer from CSO 026 to CSO 022, and a new larger sewer from CSO 022 to CSO 016. Indiana Government
     

  • Under that plan, CSO discharge points 020, 021, 025, and 026 would be eliminated. Indiana Government
     

  • Other parts of the project include a large-diameter storage/tunnel system to manage overflow from a group of other outfalls (e.g., CSOs 009, 011, 013, 014, 015). Commonwealth Engineers+1
     

So yes — there is a known plan for bypassing / intercepting certain CSOs in your area, including 026 → 022 → 016, and eliminating overflows from 020, 021, 025, and 026 (at least in design). Indiana Government+2Commonwealth Engineers+2

​

The publicly-available CSO map from IDEM should show the outfall locations and receiving streams for each CSO, which means — in principle — you or someone in your group could obtain map layers showing exactly where those CSOs discharge relative to the proposed water-park site or upstream pollution (“NPL site”, “Pittsford Ditch”, etc.).

​

Also, the City posts a “CSO Notification Program” — including a phone line (765-648-6585) and signage at waterways and parks near discharge points.
