HB 6247: Environmental protection: air pollution; regulation of carbon sequestration; provide for.

HB 6247 establishes a comprehensive regulatory framework in Michigan for the geologic storage of carbon dioxide, requiring operators to obtain permits from the Department of Environment, Great Lakes, and Energy that align with federal standards. The bill authorizes the leasing of state-owned lands and pore space for these projects, while permitting specific surface activities on commercial forestland and wilderness areas under strict conditions to protect natural resources. It creates a unitization process to manage shared subsurface interests among multiple property owners and mandates long-term monitoring of storage sites for at least 50 years after injection ceases. Upon successful completion and verification of site safety, the state assumes ownership and liability for the stored carbon dioxide, releasing the original operator from future regulatory responsibilities.

HB 6281: Transportation: motor fuel tax; areas requiring certain vapor pressure; modify. Amends secs. 3 & 10d of 1984 PA 44 (MCL 290.643 & 290.650d).

Michigan House Bill 6281 amends the Motor Fuels Quality Act to update regulations for gasoline and diesel fuel sold in the state. The bill directs the director of the Department of Environment, Great Lakes, and Energy to establish specific standards for fuel purity, additives, and octane ratings, while mandating a vapor pressure limit of 9.0 psi for most retail outlets during the summer months from June 1 to September 15. It also clarifies that certain counties with stricter air quality requirements must continue using lower vapor pressure fuels of 7.0 or 7.8 psi unless federal and state agencies determine those standards are no longer necessary. Additionally, the legislation permits the year-round sale of E15 fuel, which contains 10.5% to 15% ethanol, provided that dispensing pumps are clearly labeled in accordance with federal law.

SB 1038: Environmental protection: pollution prevention; bulk storage regulations; provide for. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding secs. 5525a & 5525b.

Senate Bill 1038 updates Michigan's environmental laws to impose stricter regulations on facilities that store, handle, or process bulk solid materials like coal and coke. The bill requires these facilities to obtain an annual certificate of operation, install real-time air quality monitors around their perimeters, and maintain detailed logs of equipment maintenance and dust control activities. Key operational changes include mandating enclosed storage for piles, limiting outdoor pile heights, enforcing vehicle cleaning and wheel washing, and requiring weather stations to monitor wind conditions for effective dust suppression. Additionally, the bill directs the state Department of Environment, Great Lakes, and Energy to issue compliance orders within 45 days of enactment, setting a schedule for full implementation of these new standards.

HB 5664: Environmental protection: air pollution; carbon dioxide capture technology; provide for. Amends secs. 5501, 5530 & 5531 of 1994 PA 451 (MCL 324.5501 et seq.) & adds secs. 5505c, 5505e, 5505g & 5505i. TIE BAR WITH: HB 5665'26, HB 5666'26, HB 5667'26, HB 5668'26, HB 5669'26

This bill amends Michigan's Natural Resources and Environmental Protection Act to establish definitions and regulatory frameworks for carbon dioxide capture projects and facilities. It creates new categories of facilities (A through F) based on their type and emission status, and adds specific definitions for carbon dioxide capture, carbon dioxide streams, and environmental justice communities. The legislation clarifies what constitutes air pollution and air pollution control equipment, while also defining fee-subject air pollutants and emissions that may be subject to fees. These changes aim to provide clearer language for regulating air quality and carbon capture activities across different types of industrial and energy facilities in the state.
