M.E.S. Vogels, NLR, May 15, Amsterdam Airport Schiphol and Its Environment New Runway 5 runways: in runways: in 2002 Reduced noise load. Benefit!!! Increased noise load. Not in populated area!!!

M.E.S. Vogels, NLR, May 15, Noise control points for L den Total Noise Volume (virtual airport) Targets are set by noise loads computed for scenario 2005 Targets in noise control points include meteo-margin Noise Target Setting (2003+) Noise control points for L night

M.E.S. Vogels, NLR, May 15, Noise Target Setting (2003+) Reasons for changing the noise target setting: –distrust of general public in modelling, forcing a transition from modelling towards measurements, hence a transition from a noise zone to a set of discrete control points –non-incorporation of noise levels below 65 dB(A) –absurdities: environmental protection against high noise loads on parking lots and beet fields –harmonisation in Europe towards L den and L night, abandoning Dutch Kosten Unit Transition from the current noise zone system involves: –changes in law –environmental impact procedure –independent assessment of information

M.E.S. Vogels, NLR, May 15, Future years... The noise development in living areas in the 53 L den contour of the transition scenario will be monitored. From noise measurements will be involved in target setting. Various options are being investigated. Harmonisation policy in Europe will be integrated into national regulations
