The City of Longmont is prohibited by Federal law from imposing limitations on aircraft operations for the purposes of controlling noise without FAA approval.
Per the Airport Noise and Capacity Act (ANCA) of 1990, an airport sponsor that wants to impose mandatory restrictions on Stage 2 and Stage 3 aircraft must address the applicable requirements of 14 CFR Part 161, Notice and Approval of Airport Noise and Access Restrictions. Typically, this requires the airport sponsor to demonstrate that proposed restrictions do not create an undue burden on interstate or foreign commerce, including any unjust discrimination. [Stage 2 aircraft are older jets used by charter and corporate users and Stage 3 aircraft are more modern jets used by large air carriers.] To read more about ANCA and airport noise, go to the following web sites:

Federal Law concerning airport noise
Even if the provisions of ANCA are not applicable, an airport sponsor still must obtain FAA’s approval to impose aircraft restrictions, per Federal grant assurances. Acceptance of Federal funds obligates an airport sponsor to make the airport available to all aircraft operators. An airport sponsor may request the FAA, per the requirements of 14 CFR Part 150 and Part 161, to allow it to implement certain restrictions on aircraft operations, but FAA will not approve a noise restriction that may violate the airport sponsor’s grant assurances, including the assurance requiring access to the airport on reasonable terms and without unjust discrimination.
Since 1982, The City has accepted over $4.7million in Federal funds under the current airport development program, the Airport Improvement Program (AIP). In accepting these funds, the City has agreed to specific Federal obligations, including a commitment to keep the Airport open and make it available for public use as an airport. Under Federal law, this obligation runs in perpetuity since the City acquired land with Federal funds.
For more information on Federal grant assurances, go to the FAA’s web page on the subject. In addition, you can call the FAA’s Denver Airport District Office at (303) 342-1354 for information specific to the Vance Brand Municipal Airport. This office issues AIP grants to the City of Longmont and works with Airport staff to ensure Airport planning and operations remain compliant with FAA standards and grant assurances.
