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 MDOT 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 impact of aircraft noise on people 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).
In 2019, MDOT 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).
