HB 5465 Michigan House · 2025-2026 Regular Session

Crimes: trespassing; prohibition against entering a key facility; expand. Amends sec. 552c of 1931 PA 328 (MCL 750.552c).

HB 5465 amends Michigan's trespassing law to criminalize unauthorized entry into specific critical infrastructure facilities, including power plants, water treatment sites, natural gas stations, chemical plants, and data centers. The bill requires these facilities to display clearly visible signage (at least 1-inch letters, 50 square inches, spaced for visibility) to warn against entry. Unauthorized entry into such facilities - when enclosed and properly posted - becomes a felony punishable by up to 4 years in prison or a $2,500 fine. The law explicitly excludes lawful, peaceful protests and labor disputes from prosecution.

MODERATE

The bill was amended to modernize the list of protected facilities by adding specific definitions for energy storage systems and expanding the scope of transportation facilities. The text also includes several formatting corrections to fix numbering errors and grammatical issues in the original draft.

Scope change

The bill's scope was expanded to explicitly include new types of energy storage systems (such as batteries and pumped hydro) and clarified the definition of transportation facilities.

DEFINITION

Added a specific definition for 'energy storage system' to include batteries, pumped storage hydroelectric facilities, compressed air, and thermal energy storage, ensuring these are covered under the key facility protections.

Updated the list of electric utility facilities to include 'energy storage systems' alongside power plants and transmission facilities.

Corrected a numbering error in the facility list, changing the final catch-all category from subdivision (l) to (n) to maintain proper alphabetical order.

TECHNICAL

Fixed grammatical errors in the signage requirements section, changing 'shall must' to 'shall' and correcting the phrase 'entry upon on' to 'entry upon'.
