Authorize counties to adopt noise ordinances

This bill authorizes Montana counties to create and enforce noise ordinances in unincorporated areas, allowing local governments to set rules about acceptable sound levels. The legislation permits counties to define specific geographic areas covered by the rules, establish time-based restrictions, and create exceptions for approved activities. If a county adopts such an ordinance, it can impose fines of up to $200 for violations, but imprisonment cannot be used as a penalty. The bill explicitly prevents these county-level noise rules from applying to areas within the boundaries of incorporated cities or towns.
