Jim and Bob, | believe | received responses from all of our districts (| copied Rich Benzie in case he
has some knowledge about the answers to your second question).
YWWIPs serving populations greater than 100,000 people:
Lansing WWTP
Flint WWTP
Genesee Co-Ragnone WWTP (Montrose)
Kalamazoo WWTP
Detroit WWTP
Warren WWTP
e Wayne CO Downriver WWTP
e YCUA WWTP (Ypsilanti Community Utilities Authority)
VWVTPs greater than 2 MGD within 5 river miles of a water intake serving a population of 100,000 or
more (our staff had problems understanding the question, so we may need more work on this}. |
started by looking at the Drinking water systems serving population greater than 100,000 in the
attached spreadsheet:
e Ann Arbor - ??, we'll need to look at this one again.
e Grand Rapids - this is a Lake Michigan intake (if memory serves me), so is the question
relevant?
e Lansing source is from the groundwater, so they don't have a river intake
e Kalamazoo source is from the groundwater, so they don't have a river intake

e Saginaw/Midland - this is a Lake Huron/Saginaw Bay intake, so is the question relevant?
e Detroit - we believe all of DWSD's intakes are more than 5 miles downstream of WWTPs > 2
mgd. We're still waiting to hear about one intake, but it appears to be OK. See attached note.
Is that the information you needed? Do we need to look at Grand Rapids and Saginaw/Midland in
WW ITP impacts since they are lake intakes?
