Memorandum
This resolution seeks approval of a general services agreement with Prolime Corporation for the removal of residual limestone from the Water Treatment Plant. Residual limestone is generated as part of the mineral removal process in production of drinking water.
The limestone residual has been designated an agricultural liming material by the Michigan Department of Agriculture and can be recycled by applying it to farmland.
