Generally revise utility laws

This bill amends Montana's utility relocation laws to clarify how costs are defined and which entities are covered. It directly affects utility companies, state highway projects, and property owners by updating the legal definitions of "cost of relocation" and "utility." The key provision specifies that relocation costs include materials, labor, and equipment but exclude engineering expenses, while expanding the definition of utility to include water, sewer, cable, and broadband providers. These changes aim to provide clearer guidelines for when and how utilities must compensate for infrastructure moved during highway projects.
