Airports & LAANC Zones

• BIL — Billings Logan International Airport (Class D airspace, 18 miles northeast, controlled airspace requiring LAANC for commercial drone ops within 5 NM)
• MLS — Laurel Municipal Airport (Class E airspace, 2 miles south of downtown, general aviation, no control tower)
• HVR — Havre City-County Airport (Class E airspace, 260 miles north, reference for statewide operations)
• BZN — Bozeman Yellowstone International Airport (Class D airspace, 145 miles west, reference for regional cross-state ops)

Restricted Airspace

• Billings Logan International Airport (BIL) has Class D airspace extending from the surface to 5,400 feet MSL within 4 nautical miles of the airport. While Laurel is 18 miles southwest of BIL, the outer edges of the BIL Class D airspace may affect operations in the northeast portion of Laurel near the I-90 corridor. LAANC authorization is required for commercial drone operations within the BIL Class D surface area. Use the FAA B4UFLY app or approved LAANC providers (Aloft, AirMap) for authorization before flying within 4 NM of BIL. Most of Laurel falls outside the BIL Class D airspace, but check the airspace boundary at your specific flight location.
• The CHS Inc. Laurel Refinery is the most significant airspace restriction in the Laurel area. The refinery, located on the south side of Laurel along the Yellowstone River and BNSF Railway corridor, is classified as critical infrastructure under FAA regulations. Drone operations over or near petroleum refineries and associated tank farms are restricted under FAA Part 107 and may trigger federal critical infrastructure protection regulations. The refinery complex includes crude oil processing units, product tank farms, rail spur infrastructure, and pipeline terminals. Drone operators should maintain a minimum 500-foot lateral distance from refinery infrastructure unless authorized, and should never fly directly over pipeline corridors, tank farms, or processing units. The refinery has its own security and monitoring systems that may flag unauthorized drone activity.
• The Yellowstone River corridor running through Laurel is a sensitive wildlife corridor. While not a formal no-drone zone, the river hosts bald eagle nests, osprey nesting platforms, and migratory bird activity, especially during spring and fall. FAA Part 107 prohibits flying directly over non-participants, and wildlife disturbance is addressed under the Migratory Bird Treaty Act. The Laurel riverfront area including the Riverfront Park and the Yellowstone River fishing access sites have high pedestrian and angler traffic. Drone operators conducting aerial mapping work along the river corridor should maintain altitude awareness and avoid low-altitude flights near documented nest sites during nesting season (March through August).
• The BNSF Railway Laurel classification yard and rail corridor is critical rail infrastructure. The Laurel rail yard is a major BNSF classification and maintenance facility on the Montana Rail Link, handling freight traffic between the Pacific Northwest and the Midwest. Drone operations over or near railroad infrastructure are restricted under FAA Part 107 and railroad safety regulations. The rail yard has locomotive maintenance facilities, a roundhouse, and classification tracks. Drone operators should maintain minimum 500-foot lateral distance from rail yard infrastructure and never fly directly over moving trains, switching operations, or maintenance activities. The BNSF Railway prohibits drone operations over rail yard infrastructure without written authorization.
• Laurel Municipal Airport (MLS) operates in Class E airspace with no control tower, located 2 miles south of downtown. While LAANC authorization is not required for Class E surface area, drone operators must comply with FAA Part 107 regulations and maintain visual line of sight. The airport serves general aviation and agricultural spraying operations. Monitor the common traffic advisory frequency (CTAF) 122.8 MHz when operating near the airport. Agricultural spray planes operate at low altitude during the growing season (May through September) — be especially vigilant and yield right-of-way to all agricultural aircraft.

Local Ordinances

Laurel does not have a comprehensive city-specific drone ordinance, relying on FAA Part 107 regulations and Montana state law. Commercial drone operators must hold a valid FAA Part 107 Remote Pilot Certificate. The Laurel Parks and Recreation Department requires authorization for commercial drone takeoff and landing on city-owned park property, including Riverfront Park, Lions Park, and the Laurel Sports Complex. Operations near the CHS Laurel Refinery are restricted under critical infrastructure protection regulations. The BNSF Railway prohibits drone operations over the Laurel classification yard without written authorization. Operations near Billings Logan International Airport (BIL) require LAANC authorization within the Class D surface area (northeast portion of Laurel). Montana Fish, Wildlife & Parks requires permits for drone operations in state parks, including Cooney State Park 35 miles southwest. Montana Code Annotated § 60-1-101 includes drones in the definition of aircraft, but the state defers to FAA authority for Part 107 commercial operations.
