All environment bills

passed both · Michigan · House Dec 16, 2025

HB 4314: Environmental protection: water pollution; removal of surface debris without a permit; allow. Amends sec. 32512 of 1994 PA 451 (MCL 324.32512).

HB 4314 amends Michigan's environmental law to allow property owners and communities to remove free-floating debris and uprooted vegetation from shorelines without a permit. Specifically, it permits mechanical or manual removal between the ordinary high-water mark and the water's edge, as long as the activity doesn't impact the lakebed. This change directly affects residents, shoreline property managers, and local groups maintaining areas along Great Lakes and Lake St. Clair shorelines. The exemption does not apply to the St. Clair River delta area in Clay Township, St. Clair County, as defined in 1899 PA 175.

SB 443: Health facilities: other; surgical smoke plume evacuation plan; require. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding sec. 20187.

SB 443 requires Michigan health facilities performing specific surgical procedures to implement policies mandating the use of surgical smoke plume evacuation systems. It directly affects hospitals and clinics conducting procedures involving heat-producing equipment (like electrosurgery, lasers, or other heated instruments), which generate harmful smoke containing vapor, gas, or particles. The bill mandates that facilities develop and enforce policies ensuring evacuation systems capture and neutralize the smoke at the surgical site before it can contact staff or patients' eyes or airways. This creates a concrete safety requirement to protect healthcare workers and patients from exposure to potentially hazardous surgical smoke.

HB 4127: Energy: nuclear; definition of advanced nuclear reactors; provide for. Amends sec. 10h of 1939 PA 3 (MCL 460.10h). TIE BAR WITH: HB 4129'25, HB 4125'25, HB 4126'25, HB 4128'25, HB 4124'25

HB 4127 adds a specific definition for "advanced nuclear reactor technologies" to Michigan's energy law. The bill defines these as nuclear reactors with significant safety improvements over pre-2016 U.S. models, including federally defined advanced reactors and existing Michigan nuclear facilities that completed life cycle management. This definition will directly affect the Michigan Public Service Commission and electric utilities when evaluating nuclear energy projects and regulatory approvals. It creates a clear standard for identifying qualifying nuclear technologies under state law, ensuring consistent application of energy regulations.

SB 396: Environmental protection: air pollution; regulation of carbon sequestration; provide for. Amends secs. 502 & 1301 of 1994 PA 451 (MCL 324.502 & 324.1301); adds sec. 52509 & subch. 6 to ch. 3 of art. III. TIE BAR WITH: SB 0394'25, SB 0395'25

SB 396 updates Michigan's air pollution laws to include specific regulations for carbon sequestration projects. It directly affects companies and organizations that capture and store carbon dioxide underground to reduce emissions. The bill adds new rules requiring safe storage practices, reporting, and oversight for these projects under the existing air pollution control framework. This amends current law to create a clear regulatory path for carbon sequestration as part of the state's air quality management.
passed · Michigan · Senate Sep 4, 2025

SB 394: Natural resources: gas and oil; ownership and conveyance rights associated with pore space; establish. Creates new act. TIE BAR WITH: SB 395'25

SB 394 establishes that landowners in Michigan automatically own the pore space (open spaces in underground rock formations) beneath their property, which can be used for storing substances like carbon dioxide. This means property buyers inherit pore space rights unless the seller explicitly transfers or excludes them in the sale agreement. The bill requires clear language in property transfers to sever pore space rights from surface ownership, protecting existing mineral rights and surface access for oil/gas operations. It does not affect mineral rights or existing agreements but requires Senate Bill 395 to pass simultaneously for full implementation. The bill aims to clarify ownership for future resource storage projects while maintaining current legal frameworks.

HB 4257: Environmental protection: solid waste; anaerobic digestion and digestate; define. Amends secs. 11502 & 11503 of 1994 PA 451 (MCL 324.11502 & 324.11503). TIE BAR WITH: HB 4265'25

HB 4257 defines key terms related to waste management, specifically for anaerobic digestion byproducts (digestate) and their "beneficial use" in agriculture or construction. It creates five distinct categories of beneficial use (e.g., soil application at agronomic rates, road base, or construction fill) with specific environmental safeguards like runoff prevention and groundwater protection. The bill directly affects waste management facilities, farmers, and construction entities handling digestate or ash by clarifying legal standards for its use. These definitions ensure consistent application under existing environmental rules, requiring materials to meet soil-nutrient balance and pollution prevention criteria.

HB 4007: Energy: alternative sources; clean energy system; expand definition of. Amends sec. 3 of 2008 PA 295 (MCL 460.1003).

HB 4007 amends Michigan's Clean and Renewable Energy Act (2008 PA 295) by expanding the definition of "clean energy system" to include natural gas plants using carbon capture and storage (at least 90% effective) and certain existing natural gas facilities that can meet clean energy standards by 2030 through carbon capture and removal technologies. This change directly affects electric providers required to meet the state's clean energy standard, as it broadens the types of energy sources that qualify toward their compliance targets. The bill specifies that carbon capture must permanently store carbon dioxide (excluding enhanced oil recovery), and permits for new facilities may require higher capture rates if deemed necessary under federal standards. This definition update provides additional pathways for natural gas projects to count toward Michigan's clean energy goals.

HB 4029: Natural resources: hunting; posting of rules and regulations by a certain date; require. Amends secs. 40113a & 41103 of 1994 PA 451 (MCL 324.40113a & 324.41103).

HB 4029 amends Michigan's Natural Resources and Environmental Protection Act to require the Natural Resources Commission to provide 30 days' notice to specific legislative committees before issuing hunting or trapping regulations. It also states that regulations not issued by June 1 will not be valid until the next hunting season. Additionally, the bill mandates the Department of Natural Resources to clearly describe any rule changes - such as affected areas, species, and duration (capped at 5 years) - and publish these in annual guides and local newspapers for three consecutive weeks in each impacted county. These provisions aim to increase transparency for hunters, anglers, and the public regarding regulatory changes.
