The bill amends the Michigan Penal Code by updating Section 552c to clarify the definition and regulations surrounding "key facilities." It specifies that an individual is prohibited from intentionally entering or remaining on premises belonging to another person that qualify as a key facility, which includes various types of utility and manufacturing facilities, as well as the Mackinac Bridge. The bill also emphasizes that these facilities must be enclosed by a physical barrier and properly posted with signage to deter unauthorized access.

Additionally, the bill outlines the requirements for signage, stating that it must be conspicuous, with a minimum letter height of 1 inch and a size of at least 50 square inches. It establishes that an individual who violates this section is guilty of a felony, punishable by up to four years in prison or a fine of $2,500. The bill also clarifies that lawful assembly or peaceful petitioning for grievances is not prohibited under this section, and it states that leaving the barrier open during normal operating hours does not serve as a defense against prosecution.
