Each year, the MSP Noise Oversight Committee (NOC) establishes a Work Plan. The 2012 Work Plan was approved during the Metropolitan Airports Commission meeting on December 19, 2011. The plan includes more action toward MSP Performance-Based Navigation (PBN) procedures, exploring use of WhisperTrack web-based technology, review of the MSP 2020 Improvements Environmental Assessment Noise Analysis, and continuing review of public input, fleet mix trends, nighttime runway use and residential noise mitigation program status.
