Bill > HB4085

This bill amends the Michigan zoning enabling act to establish clear guidelines for digital asset mining operations in industrial zones. Specifically, the bill mandates that digital asset mining (the process of using electricity to power computers or nodes to secure blockchain transactions) is automatically a permitted use in industrial zones and cannot be subject to additional special approval processes. Local governments are prohibited from creating unique sound restrictions for digital asset mining businesses beyond existing industrial zone noise pollution limits, and cannot impose zoning requirements that would not also apply to data centers in the same district. The bill provides detailed definitions for technical terms like "blockchain", "node", and "digital asset mining", and defines a digital asset mining business as a computer group consuming over 1 megawatt of energy for blockchain security. The purpose appears to be standardizing and facilitating the establishment of cryptocurrency mining operations by removing potential local regulatory barriers in industrial areas, thereby creating a more predictable regulatory environment for such businesses.
