The Maryland Environmental Noise Act of 1974 provides for the protection of citizens from the impact of transportation related noise. The aviation portion of the Act requires the Maryland Aviation Administration (MAA) to create an Airport Noise Zone (ANZ) to control incompatible land development around BWI Marshall Airport and a Noise Abatement Plan (NAP) to minimize the potential impact of aircraft noise to those living near the Airport.
The initial ANZ and NAP for BWI Marshall Airport was established in 1976, and was last updated and certified in 2021, incorporated by reference at COMAR 11.03.01.12-B(4). The MAA has completed an update to the BWI Marshall ANZ.
2025 BWI Marshall ANZ Update
In early 2025, MAA began the process to update the BWI Marshall ANZ, reflecting existing conditions in 2025, and forecast conditions in 2030 and 2035. Information about the ANZ, including Stakeholder Advisory Committee meetings, is available at the links below.
Please reach out to the MAA Project Manager, Mr. Bruce Rineer, via email at MDOT-MAA-ANZ@assedollc.com if you have any questions about the ANZ Update process.
