The ANEF for Wagga Wagga Airport is based on the same assumptions as the ANEC but with the number of movements increased to reflect the ultimate capacity forecast. The use of an ultimate capacity approach is justified on the basis that the ANEF is intended to protect the public from unacceptable impacts of aircraft noise in the long-term and is therefore very much a worst-case assessment. The maximum number of aircraft movements that could be accommodated on the proposed ultimate development runway system has been included in the ANEF. This ultimate capacity has been assessed as being approximately 315,000 movements. It can be clearly seen from Section 4.2.2 that activity at Wagga Wagga Airport is not expected to reach this ultimate capacity until many years (and quite possibly several decades) beyond 2030. The forecast level of movements in 2030 and modelled in the development of the ANEC is a little over half of this ultimate capacity, even in the worst case scenario in terms of fixed-wing flying training activity. The ANEF for Wagga Wagga Airport is shown in drawing B09065A303 included at Appendix B. The 2029/30 ANEF shows the 15, 20, 25, 30 and 35 ANEF contours. In terms of the ANEF contours that are significant under AS2021:2000: •
the 35 ANEF contour is contained within the airport boundary needed to accommodate the extent of the assumed runway layout;
•
The 30 ANEF contour only exceeds the assumed airport boundary to the north-east and south-west, extending slightly over the Sturt highway and Elizabeth Avenue respectively;
•
The 25 ANEF contour is mostly contained within the proposed adjacent development precincts, except at the ends of the runways to the south-west and north-east where it extends over portions of presently uninhabited land; and
•
The 20 ANEF contour encompasses part of the RAAF Base and the existing residential area to the east.

COMPARISON OF CONTOURS
2008/09 ANEI vs 2029/30 ANEC As expected there is an increase between the 2008/09 ANEI contours and the 2029/30 ANEC contours due to the higher forecasted level of traffic in 2029/30 and changes to the runway layout and flight paths. The shape of the more significant 30 and 35 contours on both the 2008/09 ANEI and 2029/30 ANEC contour maps are similar and centred around the existing Runway 05/23. The development of the parallel Runway 05R/23L has widened the contours more to the south over land which is predominantly open pasture. The 20 and 25 ANEC contours extend farther out from the runway ends than those of ANEI. Ref:B09065AR001Rev6.doc
