Michigan Compiled Laws, Chapter 324. Natural Resources and Environmental Protection § 324.3133

Sec. 3133. (1) Except as otherwise provided in this section, sections 3131 and 3132  1 preempt a local ordinance, regulation, or resolution of a local unit that would duplicate, extend, revise, or conflict with section 3131 or 3132. Except as otherwise provided for in this section, a local unit shall not enact, maintain, or enforce an ordinance, regulation, or resolution that duplicates, extends, revises, or conflicts with section 3131 or 3132.

(2) The director of the department of environmental quality may contract with a local unit to act as its agent for the purpose of enforcing this section and sections 3131 and 3132. The department shall have sole authority to assess fees. If a local unit is under contract with the department of environmental quality to act as its agent or the local unit has received prior written authorization from the department, then the local unit may pass an ordinance that is identical to section 3132 and rules promulgated under section 3131, except as prohibited in subsection (4).

(3) A local unit may enact an ordinance prescribing standards in addition to or more stringent than those contained in section 3132 or in rules promulgated under section 3131 and which regulate a sewage sludge or sewage sludge derivative land application site under either or both of the following circumstances:

(4) An ordinance enacted pursuant to subsection (2) or (3) shall not conflict with existing state laws or federal laws. An ordinance enacted pursuant to subsection (3) shall not be enforced by a local unit until approved or conditionally approved by the director of the department of environmental quality under subsection (5). The local unit shall comply with any conditions of approval.

(5) If the legislative body of a local unit submits to the department of environmental quality a resolution identifying how the requirements of subsection (3)(a) or (b) are met, the department shall hold a public meeting in the local unit within 60 days after the submission of the resolution to assist the department in determining whether the requirements of subsection (3)(a) or (b) are met. Within 45 days after the public meeting, the department shall issue a detailed opinion on whether the requirements of subsection (3)(a) or (b) are met as identified by the resolution of the local unit and shall approve, conditionally approve, or disapprove the ordinance accordingly. If the department fails to satisfy the requirements of this subsection, the ordinance is considered to be approved.
