Michigan Dept. of Environment, Great Lakes, and EnergyThis layer contains some, but not all, county and local solutions to pollution issues related to E. coli in Michigan. County and minor civil division boundaries are the spatial basis of this layer, which also contains links to the local health department web site, status of local septage and septic system regulations, and Michigan Agriculture Environmental Assurance Program (MAEAP) verifications numbers by township. All information is updates about once per year. Information includes: Septage Land-Application Prohibited: State regulations allow local municipalities and counties to prohibit the land-application of septage. Domestic septage is defined as the solids that settle in an on-site septic system tank, which must be pumped and hauled away. Septage can be land applied at a site permitted by Michigan Department of Environment, Great Lakes, and Energy (EGLE) in accordance with state law to ensure pathogen reduction and so the nutrients are utilized by crops as a fertilizer. Septage is regulated by Michigan's 2004 Public Act 381, which amended Part 117, Septage Waste Servicers, of the NREPA. Legal Disclosure: EGLE may not know of all local ordinances, so you may wish to check with your county and/or municipality to verify local ordinances. Updated: June, 2020. Counties with Time-of-Sale/Transfer Ordinances (TOST): Time-of-sale septic system ordinances (also known as TOST) may be enacted at the local level. These ordinances are beneficial because they provide a means for local health departments to inspect on-site septic systems during property transfer, instead of just at the time of repair or installation. Michigan Agriculture Environmental Assurance Program (MAEAP): MAEAP is a voluntary program established by Michigan law and administered by Michigan Department of Agriculture and Rural Development and local conservation districts. MAEAP verified farms have met a series of benchmarks demonstrating that their management practices are environmentally sound. MAEAP verifications offer benefits to water quality and to the farmer. The number of verifications provided in the map are township-wide. The number of MAEAP verifications for livestock systems and cropping/farmstead systems are listed.
