Request for Proposals: Mid-Michigan Lime Calciner Feasibility Study

Updated: Apr 19

Updated: April 2, 2024

The Tri-County Regional Planning Commission (Tri-County), on behalf of the Mid-Michigan Regional Lime Calciner Committee, is seeking proposals from professional engineering firms to conduct a Mid-Michigan Lime Calciner Feasibility Study. There are 10 entities involved in the project. The study shall evaluate the feasibility of each entity’s participation in a regional calciner (also known as a lime kiln). The participating entities are:


  1. Lansing Board of Water & Light

  2. City of Jackson

  3. City of Ann Arbor

  4. East Lansing Meridian Water & Sewer Authority

  5. Plainfield Charter Township

  6. City of Owosso

  7. City of Mount Pleasant

  8. City of Howell

  9. Marion-Howell-Oceola-Genoa Sewer & Water Utilities

  10. City of Fenton


The regional nature of this project makes it necessary to have a detailed analysis of the residual from each entity and a determination if the residuals can be appropriately blended to provide a high-quality lime from the calcining process. Additionally, a completed feasibility study will identify the best type of lime kiln for mid-Michigan, determine potential site locations and transportation options, complete a financial analysis and identify options for ownership, and conduct an environmental and economic analysis of the facility.


Interested candidates’ submissions should include a concise statement of the consultant's approach to the project and a summary of the consultant's ability to provide the required services.
