The bill amends the Natural Resources and Environmental Protection Act, focusing on the responsibilities of the Department of Natural Resources in managing Michigan's natural resources. It introduces new definitions for terms such as "Commission," "Department," and "Aquatic nuisance species," clarifying the Department's role in water resource management, including flood control and aquatic nuisance species management. The bill also modifies floodplain permit requirements, establishing a new fee structure and minor project categories, while streamlining the application process to allow for combined applications. Public hearings and environmental assessments are emphasized to ensure careful regulation of floodplain alterations.

Additionally, the bill outlines new fee structures and regulatory requirements for various environmental permits, including those related to hazardous waste, stormwater discharge, and mining operations. It mandates annual adjustments to fees based on the Detroit Consumer Price Index starting January 1, 2026, and establishes penalties for late payments. The bill also enhances public engagement in the mining permit process by requiring written notice of public meetings and a structured timeline for public comments. Overall, the amendments aim to improve regulatory oversight, enhance environmental protection, and ensure compliance with updated fee structures across multiple areas of natural resource management.
