Define public purpose of easements on state lands

This bill clarifies the specific purposes for which easements can be granted on Montana state lands, affecting entities seeking to use state property for public and private infrastructure. It updates existing statutes to explicitly list allowed uses including public trails, parks, cemeteries, utility lines, and private access roads that existed before 1997, while also adding special provisions for certain conservation areas and nonprofit organizations. The legislation streamlines application requirements by allowing certain projects like power lines and water systems to use less detailed surveys, while maintaining stricter survey standards for other types of easements to ensure accurate land descriptions.
