Bill > HB4265

This bill amends Michigan's environmental protection laws to modify regulations for solid waste management, with a particular focus on anaerobic digesters. The bill updates the definition of solid waste to include digestate from registered anaerobic digesters and establishes comprehensive new requirements for anaerobic digester operators. Key provisions include mandatory quarterly testing of digestate to ensure safety, specific guidelines for acceptable feedstock materials, and a registration process that requires operators to submit detailed contingency plans and pay a $750 fee. The bill also specifies acceptable sources for digester feedstock, which range from livestock manure and animal bedding to food waste and crop residuals. Additionally, registered anaerobic digester operators must maintain detailed records, complete operator training within one year, and submit custody transfer forms identifying feedstock sources and digestate recipients. The bill aims to create a more structured and environmentally responsible framework for managing organic waste through anaerobic digestion, with provisions to protect public health and environmental safety.
