HB 355 Utah House · 2025 General Session

Mining and Critical Infrastructure Materials Amendments

HB 355 modifies Utah's laws governing sand, gravel, and rock aggregate operations (defined as "critical infrastructure materials") to protect existing operators' rights. It creates a "vested critical infrastructure materials use" for operations established before January 2019, allowing operators to expand to contiguous land they own or control by May 7, 2025. The bill enables operators to extend, enlarge, or modernize their operations on this land without losing protected status, while requiring them to file declarations recording their rights. It repeals a study requirement and makes technical updates to related statutes, affecting current operators but not creating new permitting processes.

MODERATE
This bill updates Utah's laws regarding mining and critical infrastructure materials (like sand, gravel, and rock) to treat them more like traditional mining operations. The changes clarify definitions, establish stronger legal protections for existing operations, and allow operators to expand onto new land with fewer restrictions than before.
Scope change
The bill expands the legal protections and operational rights for 'critical infrastructure materials' operators, aligning their rules more closely with those for traditional mining operators.
DEFINITION

The definition of 'vested critical infrastructure materials use' was updated to include operations that existed before January 1, 2019, ensuring they are protected even if local rules change later.

ELIGIBILITY

Operators with vested rights can now expand their operations onto 'new land' (land owned or controlled by January 1, 2026) with a presumption of the right to do so, provided they notify local officials.

REQUIREMENT

The process for expanding to new land was streamlined; local governments must hold a public hearing within 30 days of notice and can only block expansion if they prove it endangers public health, safety, or welfare.

A requirement to conduct a study on critical infrastructure materials operations was repealed.

TIMELINE

The effective date for the bill was set to May 7, 2025, and the deadline for operators to gain control of new land was set to January 1, 2026.

ENFORCEMENT

Local governments are now restricted from changing zoning or enacting new regulations that would prohibit or restrict vested critical infrastructure materials operations.
