Press releases:
KBJC - Flight Path Changes Memo - The June 10, 2025 FAA memorandum outlines new operational restrictions at Rocky Mountain Metropolitan Airport (BJC) effective June 16, 2025, in response to high rates of safety incidents. The changes include tighter rules for pattern traffic, runway occupancy, and sequencing of IFR arrivals, requiring standardized 5-mile finals and stricter runway change coordination. Departures are subject to new altitude and routing restrictions, particularly ensuring jets and high-performance props maintain priority. VFR arrivals and departures are given defined routing points, while helicopters face stricter routing, altitude, and taxiway limitations. Line Up and Wait (LUAW) is explicitly prohibited. The stated goal is to simplify operations and improve safety, with a collaborative working group beginning June 24 to review and refine these procedures before they are incorporated into the standard operating procedures - June 10, 2025
Town of Superior Response - The December 22, 2023 letter from the Town of Superior, through its attorney, responds to Jefferson County’s August 2023 correspondence regarding noise and emissions from Rocky Mountain Metropolitan Airport (RMMA). The Town criticizes the County for dismissing proposed solutions while offering none of its own, reiterating concerns about flight school training operations causing excessive noise and lead pollution over residential areas. The letter welcomes news of a Part 150 Study and Noise Compatibility Program but demands written confirmation and inclusion in the process to ensure meaningful noise abatement measures. It argues that ANCA does not apply to most RMMA aircraft, making restrictions such as landing fees, curfews, touch-and-go limitations, and preferential runway systems legal options for noise mitigation. The Town urges the County to act swiftly and decisively to reduce the health and safety impacts of airport operations on surrounding communities - December 22, 2023
Letter to CO AG from the following organizations: AOPA, GAMA, HAI, NBAA, NATA - The October 19, 2023 joint letter to Colorado Attorney General Philip Weiser was submitted by several national aviation associations to provide context ahead of a community listening session on general aviation airports. The letter emphasizes that public airports are vital to local economies, emergency response, and transportation, while also noting that concerns about noise, emissions, and flight paths fall under federal jurisdiction. It explains that the FAA has exclusive authority over airspace, flight operations, and aircraft noise, while the EPA regulates aircraft emissions under the Clean Air Act—preempting state or local regulation. The associations stress that while progress is being made toward unleaded aviation fuel through the FAA’s EAGLE initiative, current safety and operational requirements still necessitate leaded AvGas. They urge the Attorney General to balance community concerns with the legal and practical realities of maintaining national aviation infrastructure and reaffirm their commitment to collaborative, informed dialogue - October 19, 2023
RMMA Press Release Unleaded Fuel Transition - The October 4, 2023 press release announces that Rocky Mountain Metropolitan Airport (RMMA) and Jefferson County officials are accelerating the airport’s transition to unleaded aviation fuel, aiming to complete the switch by fall 2024—three years ahead of the FAA’s 2030 deadline. RMMA is already shifting to UL94 unleaded fuel, compatible with two-thirds of its fleet, supported by new fuel storage and transport infrastructure. The airport also plans to fully adopt 100UL, an unleaded option suitable for all piston aircraft engines, within two to three years as production scales up. Leaders emphasized that this initiative reflects innovation, community collaboration, and a balance between economic growth and quality of life. RMMA, Colorado’s third-busiest airport with over 400 aircraft and 50 businesses, generates an estimated $731 million in annual economic impact . - October 4, 2023
Fuel Transition Timeline - The FUEL TIMELINE document from Rocky Mountain Metropolitan Airport (RMMA) outlines the airport’s transition plan toward unleaded aviation fuel. It presents a phased approach starting with the adoption of UL94 unleaded fuel, already compatible with a significant portion of the fleet, followed by full transition to 100UL once it becomes commercially available. The timeline emphasizes RMMA’s goal of eliminating leaded fuel ahead of federal deadlines, positioning the airport as a leader in Colorado’s move toward cleaner aviation practices. It highlights the airport’s investment in infrastructure to support storage and distribution, and frames the effort as both an environmental responsibility and a commitment to community partnership
Fuel FAQ - The FUEL FAQ document explains Rocky Mountain Metropolitan Airport’s (RMMA) staged plan to transition from leaded to unleaded aviation gasoline. Starting in fall 2024, RMMA will provide UL94 unleaded fuel, compatible with about two-thirds of its fleet, while awaiting the broader availability of 100UL, which works in all piston aircraft. The transition cannot happen immediately because UL94 is unsafe for many aircraft types, so RMMA is prioritizing safety and gradual adoption. The FAQ also details federal oversight by the FAA and EPA, cost concerns for pilots and tenants, and RMMA’s efforts to mitigate expenses through FAA grants and rent incentives for flight schools. The airport anticipates completing the full transition within two to three years, well ahead of the FAA’s 2030 deadline, with the final challenge being scaling up national production and distribution of 100UL
