LANSING, Mich., June 13, 2025 — This week, the Michigan House passed House Bills 4265 and 4257 on a 62-35 vote. The bipartisan package would amend the Natural Resources and Environmental Protection Act (NREPA) to clarify when an individual owning or operating an anaerobic digester needs to register, as well as the application process for registration. The legislation now advances to the Senate for further consideration. After the vote, state Rep. Joey Andrews (D-St. Joseph), sponsor of HB 4265, issued the following statement:
“The bills aim to support clean energy and sustainable agriculture while strengthening local economies by streamlining the permitting process for methane digesters, which convert organic waste into renewable energy and fertilizer. This bipartisan legislation supports Michigan’s potential to become the national leader in this industry while advancing the state’s clean energy goals. By providing clear guidance and regulatory clarity, this effort supports agricultural innovation, helps Michigan farms manage waste sustainably and provides new economic opportunities through renewable energy generation and nutrient recycling.
“This legislation requires permits to be approved or denied within 180 days, which helps speed up the permitting process and reduce delays. It’s a win for farmers, the environment and Michigan’s economy.
“Michigan’s regulatory framework needs to keep pace with evolving clean technology. Clarifying the rules around the production of digestate is critical to ensuring that solid waste is disposed of safely and that there are contingency plans in place in the event of an emergency. These bills provide farmers with a clear path forward and much-needed clarity for digesters that play a critical role in Michigan’s food production system.”
