Montana's Senate Bill 46, introduced on January 30, 2025, aims to revise registration fees for underground petroleum and hazardous substance storage tanks. Proposed by Senator J. Esp at the request of the Department of Environmental Quality, the bill seeks to increase the annual registration fees significantly, raising the maximum fee for larger tanks from $108 to $300, and for smaller tanks from $36 to $100.

The primary goal of this legislation is to enhance the state's ability to manage and mitigate risks associated with underground storage tanks, which can pose environmental hazards if not properly monitored and maintained. The increased fees are intended to support the implementation of a robust underground storage tank program, covering costs related to inspections, compliance, and corrective actions in case of leaks.

Debate surrounding the bill has centered on the financial impact on tank owners, particularly small businesses that may struggle with the increased costs. Proponents argue that the higher fees are necessary to ensure environmental safety and to fund essential regulatory activities, while opponents express concern about the potential burden on local businesses and the economic implications of increased operational costs.

The bill's passage could have significant implications for Montana's environmental policy and public health. Experts suggest that by strengthening regulations and funding, the state could better prevent leaks and contamination, ultimately protecting groundwater and public resources. However, the increased fees may also lead to pushback from stakeholders who feel the financial strain could outweigh the benefits.

As the legislative session progresses, the outcome of Senate Bill 46 will be closely watched, as it reflects broader concerns about environmental stewardship and economic viability in Montana. The bill's immediate effective date, if passed, would mean that changes could be implemented swiftly, impacting both regulatory practices and the financial landscape for tank operators across the state.
