*Machinery was in use during the monitoring, which caused the day value to rise.

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

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.

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
