Environmental protection: solid waste; reporting and compliance requirements for anaerobic digesters; modify. Amends secs. 11506 & 11568 of 1994 PA 451 (MCL 324.11506 & 324.11568). TIE BAR WITH: HB 4257'25

The document header was updated to reflect the bill's new status as a substitute version (H-1) rather than the original House version.

The indentation of the text defining 'Solid waste' and its exclusions was adjusted to align with standard formatting, without altering the legal meaning.

Added specific exclusions to the definition of 'solid waste,' such as manure, liquid waste, and scrap metal, to clarify what materials are not subject to solid waste regulations.

Expanded the definition of 'source-separated material' to include a comprehensive list of organic waste (e.g., food scraps, yard waste), industrial byproducts (e.g., flue gas desulfurization gypsum), and specific recyclables.

Added strict requirements for anaerobic digesters, including mandatory quarterly testing of digestate for pathogens and nutrients, and a requirement to use only specific types of organic feedstocks.

Mandated that anaerobic digesters operating off-site feedstock must register with the state and submit a detailed contingency plan for biological failures or operational interruptions.

Established a phased timeline for facility registration, requiring smaller facilities to register within one year and larger facilities within two years of the act's effective date.

Authorized the department to issue orders to cease operations for digesters that fail to complete required corrective actions after receiving a notice of noncompliance.
