The licensing and handling of domestic septage is regulated under 2004 Public Act 381, which amended Part 117, Septage Waste Services, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended. The Michigan Department of Environmental Quality (MDEQ), Water Bureau administers the septage program with the assistance of participating county health departments. Kalamazoo County no longer administers this program. All questions concerning septage should be directed to the MDEQ Septage Program.
regulation requires all septage pumped from septic tanks that is within 15 miles of a
wastewater treatment facility be disposed of at such facility. Note the map at right showing
two 15-mile radius circles. The larger circle depicts the land area in Kalamazoo County that
is 15 miles from the Kalamazoo Wastewater Reclamation Plant. The smaller circle section depicts
the additional land area in Kalamazoo County that is 15 miles from the Three Rivers Wastewater
Treatment Plant. If a property lies within one of these areas, the septage must be disposed at
a treatment facility. Septage haulers are asked to complete a Septage Pumping Information
sheet after cleaning septic tanks.
There are currently no licensed private land application sites for residential septage within Kalamazoo County.
Biosolids are the nutrient-rich organic materials resulting from the treatment of sewage
sludge (the name for the solid, semisolid, or liquid untreated residue generated during the
treatment of domestic sewage in a treatment facility). Biosolids can be safely recycled
and applied as fertilizer to sustainably improve and maintain productive soils and stimulate
plant growth. The EPA permits
this type of land application of waste generated from municipal water treatment facilities.
