Biosolids Laws and Rules Information
On June 18, 1997 the governor signed 1997, PA 29. Act 29 amended the Natural Resources and Environmental Protection Act, 1994 PA 451 (NREPA) by amending section 3101 (MCL 324.3101) and by adding sections 3131, 3132, and 3133 providing for a fee-based statewide biosolids management program. These changes to part 31 of NREPA provided new ability to better manage the land application of sewage sludge (biosolids) and sewage sludge derivatives.
The Part 24 Biosolids Rules of Part 31, Water Resources Protection, of the NREPA, became effective on November 2, 1999. The rules establish standards consisting of general requirements, pollutant limits, management practices and operational requirements for the beneficial land application of biosolids.
The state statute and Rules are consistent with the federal title 40, Code of Federal Regulations, Part 503 rule.
