MSP Noise Oversight Committee (NOC)

The MAC established the MSP Noise Oversight Committee (NOC) in August 2002 to bring industry and community representatives together to address aircraft noise issues at MSP and to bring policy recommendations to the Metropolitan Airports Commission. The cities of Bloomington, Eagan, Mendota Heights, Minneapolis and Richfield each have a representative on the committee. The cities of Apple Valley, Burnsville, Inver Grove Heights, St. Louis Park, St. Paul, Sunfish Lake, and Edina are represented through an At-Large membership. Each representative serves a two-year term and each city appoints its representative and an alternate. The At-Large cities appoint one representative and one alternate from their member cities to represent all of them for the two-year term. The aviation industry is represented by a Scheduled Air Carrier, a Cargo Air Carrier, a Charter/Scheduled Operator, a Chief Pilot of an airline serving MSP, the Minnesota Business Aviation Association (MBAA) and an At-Large member. All industry representatives, except the MBAA representative, are appointed by the MSP Airline and Airport Affairs Committee. More information about the NOC can be found in its bylaws.

NOC Work Plans and Accomplishments

Each year, the NOC establishes a Work Plan. View the 2015 NOC Work Plan. Please see the list below for past NOC accomplishments.
