Subject: Operational Impact Statement for MSP–Runway 30R/12L Construction.

1. **DESCRIPTION OF AIRPORT CONSTRUCTION PROJECT:**

MSP Runway 30R/12L will be closed for resurfacing of the center portion of the runway beginning August 18, 2009.  Construction is projected to last 66 working days.  The runway will reopen on October 30, 2009.

2. **SCHEDULED DATES/TIMES :**

MSP Runway 30R/12L will be closed for construction beginning 8/18/09 @ 1200Z (0700 lcl) until 10/30/09.  Localizers for 30R/12L will be turned off during the construction period.    

3. **OPERATIONAL IMPACT:**

The loss of the north parallel runway will have a major impact on AAR/ADR at MSP.  Temporary Runway configurations designed for this construction will be used.  VFR weather will be the main concern to keep AARs at their optimum and for the use of LAHSO on Runway 22. 

Below is a chart indicating available Runway configurations, the associated AAR/ADR, and other constraints.

**Runway Configurations to be used during construction period**

**August 18 – October 30, 2009**

* Weather minimums for landing Rwy 35 and 30L >   1,700/4

* Weather minimums for landing Rwy 17 and Rwy 22 > 1,400/4

** **Higher AARs on 30L/35 are dependent on departure demand**

**Periods may exist where AAR is 50 when Rwy 35 spacing is reduced**

**to 3.5 and Runway 30L is reduced to 7 miles.**

#### ILS/LOC Approaches available

Rwy 35 = Cat III  

Rwy 12R = Cat III

Rwy 30L = Cat II

Rwy 22 = Localizer Approach

Rwy 4   = Localizer Approach

Rwy 17 = Localizer Approach  

**4.   DELAYS:**

Computer modeling by the Metropolitan Airports Commission (MAC), their engineers, and the FAA predict delays will range from approximately 6-20 minutes per aircraft depending on the weather conditions and runway configuration.  

**5.   TRAFFIC MANAGEMENT INITIATIVES (TMIs):**

Traffic Flow Management will keep the customer informed of any change to equipment status, construction progress, and approach availability.

**6.****USER COORDINATION:**

All major customers have been briefed and a follow up email was sent to their respective dispatchers.  NWA/MAC/MSP ATCT/ZMP have been involved in the preparation for the construction since summer 2008.

**7.****GENERAL INFORMATION:**

The Arrival Distance Window (ADW) will be used when operating on the 35/30L configuration.  Converging Runway Display Aid (CRDA) will also be used for both the north and south flow operations.

**8.  Contact Information**

Construction update telecons will be held Monday – Friday at 0600 and 1400 local and at 1400 on weekends for MSP, ZMP, M98, ATCSCC, MAC, and Customers. Dial in number is 612-713-4082.  No pass code required.
