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 Martin State Airport and a Noise Abatement Plan (NAP) to minimize the potential impact of aircraft noise to those living near the Airport.
The initial ANZ for Martin State Airport was established in 1977, and was updated and certified on December 24, 2012, incorporated by reference at COMAR 11.03.01.01-B(6).
2025 MTN ANZ Update
In early 2025, MAA began the process to update the MTN Marshall ANZ. The updated ANZ will reflect existing conditions in 2025, and forecast conditions in 2030 and 2035. MAA has convened a Stakeholder Advisory Committee that will meet throughout the year and will host a public information meeting/public hearing near the end of 2025. The 2025 ANZ, once complete, will be the certified regulation and replace the 2020 ANZ. 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.
2020 MTN ANZ Update
In 2019, the MAA initiated an update to the MTN Marshall ANZ. The ANZ is determined by a composite of three noise contours: existing conditions (2019) and two forecast years (2025 and 2030). The largest of the three contours in any area around the Airport determines the Noise Zone, thereby offering protection within the largest of the existing or future noise exposure contours. The noise environment around an airport is described by contours of equal noise exposure, representing the noise that occurs during an average 24-hour day, in terms of the Day-Night Average Sound Level (DNL, Ldn).

A Public Workshop and Public Hearing for the MTN ANZ update was held virtually on Tuesday, January 26th, 2021. The Public Workshop and Public Hearing provided an opportunity for all interested persons to learn, ask questions, and comment on the ANZ. A presentation that provided an overview of the ANZ update process and the contour maps depicting the current and proposed boundaries of the MTN ANZ was given, and can be reviewed here.
