Title
Resolution to Approve a Memorandum of Agreement with Tri-County Regional Planning Commission and Other Municipal Utility Partners to Complete a Mid-Michigan Regional Lime Calciner Feasibility Study (Not-to-Exceed $38,025.00)
Memorandum
This memorandum and resolution requests approval of a Memorandum of Agreement with Tri-County Regional Planning Commission, City of Jackson, Lansing Board of Water & Light, East Lansing Meridian Water & Sewer Authority, Plainfield Charter Township, City of Owosso, City of Mt.

Approval is also sought to delegate staff from the Water Treatment Services Unit to represent Ann Arbor during the completion of the study.
Ann Arbor Water uses lime in the drinking water treatment process to reduce hardness. This process, called lime softening, requires trucking of pebble lime to the water treatment facility and disposal of lime solid residuals generated during the softening process. The Ann Arbor Water Resource Recovery Facility also uses lime in the wastewater treatment process. Ann Arbor Water is genuinely concerned with security needs, competitive bids, cradle to grave product management, environmental impacts and potential regulatory changes related to lime supply and residual disposal.
Municipal water utilities that utilize lime in their treatment process face similar challenges with procurement and disposal. Several years ago, the ten water utilities listed above, with support from the Tri-County Regional Planning Commission, began discussing these shared challenges and identified the need for a study to evaluate the feasibility, including cost, logistics, environmental and economic impacts, and water utility operational needs, of building a lime calciner facility. A facility such as this would recycle lime for reuse.
The eleven participating local water util...
