Item 4 Noise Monitoring Study West and Northwest of MSP: Fall 2014 A Noise Monitoring Study is proposed for the cities of Edina and St. Louis Park The recommended study elements are as follows: The noise monitoring will be focused on assessing existing aircraft noise levels. The noise monitoring will be conducted for a period of two weeks in the fall of 2014. The monitoring will be limited to three locations in the area bound by I 494 on the south, Xerxes Avenue on the east from the intersection of I 494 and Xerxes Avenue extending in a straight line north to I 394, I 394 on the north, and Trunk Highway 169 on the west. Two of the monitoring locations will be in the City of Edina and one will be located in the City of St. Louis Park. The specific location of the monitors shall be determined by the respective cities, in consultation with MAC staff. No monitor may be located within two miles of another permanent noise monitor. The final report is due by December 1, 2014.
Item 4 2013 Annual Actual Noise Contour Report
Item 4 (continued) REQUESTED ACTION THE NOISE OVERSIGHT COMMITTEE DIRECTS THE MAC NOISE PROGRAM OFFICE STAFF TO CONDUCT THE NOISE MONITORING STUDY AS DETAILED, IN THE CITIES OF ST. LOUIS PARK AND EDINA. THE NOISE MONITORING REPORT SHALL BE COMPLETED BY DECEMBER 1, 2014 AND BE PROVIDED TO THE NOISE OVERSIGHT COMMITTEE AND THE PARTICIPATING CITIES.
Item 5 Runway Use Study 2012 2013 Overview The Runway Use System (RUS) for Minneapolis St. Paul International Airport (MSP), a defined list of runway prioritizations for arrival and departure procedures, is intended to reduce noise impacts in denselydeveloped residential areas to the west and northwest of the airport. The RUS gives first priority to departures and arrivals over open space, the Minnesota River, wetlands, and noise compatible commercial and industrial areas located to the south and southeast of MSP. Air traffic control at MSP is solely the responsibility of the FAA.

Item 5 (continued) Findings During the nighttime hours, when the wind speeds are low and air traffic volumes are reduced, the RUS is utilized to reduce noise impacts to the northwest and west of MSP. The departure operations are placed on Runways 12L/R and 17. This south flow configuration places arrivals on Runways 12L/R and has resulted in an increase in arrival noise impacts in residential areas located on the extended centerline of Runway 12R at night. When feasible, these impacts may be mitigated by using both Runway 12L and Runway 35 for more nighttime arrival operations.
Item 6 Continue Review of Runway 35 River Visual Approach Procedure The purpose of this procedure would be to reduce aircraft arrival overflights of residential areas south of MSP. Aircraft using this procedure would approach from the southwest, flying a 65 heading over the river. As an aircraft nears the airport, it would turn on to final approach and align with Runway 35. 45

Item 6 (continued) The Performance Based Navigation Standard Terminal Arrival Routes proposed by the FAA for implementation at MSP do not include the Runway 35 River Visual Approach procedure. 47
Item 7 2 nd Quarter Public Input Meeting Review April 22, 2014 at the MAC General Offices 11 attendees, 3 speakers Topics: Routing of aircraft arrivals over non residential land uses (highway 77) Increased use of Runway 30L for departures to the northwest and west of MSP Concern that the Remote Monitoring Towers located to the northwest and west of MSP do not measure noise in communities further west of MSP 48
