30. Conclusions No increase in overall noise values in 2009 Residences closer to roads had increased overall sound values Comparing noise values to other industry standards, communities around YBW meet these This does not infer there is no impact from YBW’s operations, but it does provide and understanding of the level of sound levels in the community 30

31. Jet Restriction Currently from 11PM to 7AM jets restricted SABPA have requested this restriction lifted The Authority has requested some quantification of the impact before taking it to the committee for review. Military jets that are unclassified from a noise emission perspective will continue to be restricted. 31

32. Code C Aircraft The Authority has granted limited authorization for smaller code C aircraft other than ASRD to operate at YBW for maintenance Each flight occurrence would be required to be authorized in advance Hours and flight profiles to be restricted 32
