Let's build together, better tomorrow and better Narita Airport

Basic ideas of environmental countermeasures and measures for co-existence (overview)
We will carry out countermeasures in a larger region based on the noise contours of 500,000 times. We will also examine andconsult with organizations concerned on the points that have been strongly requested to be improved but not yet done, newWe listen earnestly and discuss openly
for the future of the community and Narita

countermeasures against night and early morning flights, and measures for regional development as follows;■Noise contours and enlargement of area to be covered■Upgrade of the noise control works• Effects of the noise in the case of the number of departure and arrival
slot s of "50 0,0 0 0 times" will be estimated and environmental
countermeasures such as the noise control works and the compensation for relocation expenses will be carried out in a larger area.
• Relaxation of restrictions on night flights will be taken into consideration.
• Ef fec ts of noise that would be generated by construc ting "therunway for crosswind" that was planned at the opening of the airportwill not be examined hereafter because the construction will not beexecuted in the future.

• We consider the aid that does notexceed the total price of special

■Raise the amount of grant for countermeasuresin the surrounding area

■No more dividing the small community (village)
by contours line

• We consider the advance raise of total amount of grant because thenumber of households based on the noise contours at 500,000 times
is increased and the calculation method of the annual number ofdepartures and arrivals is changed to the calculation based on theairport capacity.

• We will consult with organizations concerned with reference to thenoise contours of 500,000 times.

[Current] per household: 300,000 times,
per landing fee: 230,000 times (actual number)[Planned] per household: 500,000 times,
per landing fee: 500,000 times (airport capacity)• Review of allocation method
We consider a more effective support for development efforts bymunicipal government in the area under noise strain of a certain
level by preferentially allocating a fixed amount of grant as "Regional
promotion slot" from the annual grant, with their financial capability
taken into account.

Japan is sliding into a phase of serious aging society with fewer children. To increase
the number of foreign visitors and to make the tourism a key industry is one of the national
strategies. Narita Airport, the major gateway of Japan, needs to work on further airport capacity

• We will continue to sincerely consult with organizations concerned on

on measures for co-prosperity and other various problems.

• We consider a more effective support for development efforts bymunicipal government in the area under noise strain of a certain

■It is necessary to expand the site by 1,000ha in order to achieve the 500,000 annual departure and arrivalslots.

■Considering the designated city planning area and the residential area in the surrounding area of Airport, thecandidate area for an expanded airport site will be as follows;

Lden (Time-zone corrected day-evening-night equivalentsound level, unit:[ dB ])Lden is an evaluation index of ambient criteria for aircraft
noise and is used to evaluate the noise in APD and ASM. It
represents the amount of noise in a day with the correctedvalue of +5dB in the evening hours (19:00-22:00) and +10dB
in the nighttime (0:00-7:00 and 22:00-24:00) when the noiseis heard louder than it actually is.
