Let's build together, better tomorrow and better Narita Airport[ Report on Capacity Enhancement of Narita Airport, vol.4 ]Our revised plan for relaxation of restrictions on night operation
About operational hours
Based on requests from the local communities and from the viewpoint of maintaining both Narita Airportʼs international
competitiveness and preserving the living environment of local residents, we have re-examined the following to ensure that
6 quiet hours under the flight routes can be achieved:[Until Runway C becomes operational]■Taking additional environmental countermeasures in advance, for areas influenced by flights from/to Runway A, we will
amend the original plan of a three hour extension of operating hours and extend current operating hours by one hour,from 6:00 to 0:00. (However, flexible operation* will be implemented for 30 minutes from 0:00 to 0:30.)■These measures will be implemented by the 2020 Tokyo Olympic and Paralympic Games.
[After Runway C becomes operational]■We will put the "sliding operation" system into practice in which different operational hours will be adopted for eachrunway, and change the overall operational hour from 5:00 to 0:30 while maintaining 6 quiet hours under the flightroutes. (However, flexible operation will be implemented for 30 minutes from 0:30 to 1:00.)* This is a system limited only to those flights that are allowed to operate due to unavoidable circumstances in order not to disrupt its scheduled operation.

Basic thoughts of environmental countermeasures and measures for co-existence (overview)
We have summarized each unresolved issue that have been strongly requested to be improved, new countermeasures for late night andearly morning flights and measures for local community development and have reflected opinions from the local community at the
explanatory meetings conducted after the Four Party Council in September last year as well as requests and desires for "review ofrelaxation to night operation restrictions", "no more fragmentation of small communities (villages)", "countermeasures against falling
objects from airplanes" and "well-balanced development of areas around the airport " made by Chiba Prefecture and the “Liaison Councilof Local Governments Around Narita Airport”. We will examine and make adjustments towards realization and pursue the following
course of action:* Those contents of the proposal that have been added and/or changed to date are shaded in blue.
■Enlargement of noise contours and areas where aircraft noise
abatement measures should be implemented■No more fragmentation of small communities (villages) by contour
boundaries• Effects of the noise for "500,000 flights" will be estimated and environmental
countermeasures such as the noise abatement works and the compensation forrelocation expenses will be carried out in a larger area.
• Rela xation of re s tric tions on night oper ation will also be t aken into
consideration. (Noise contours will be made, based on our revised plan.)• As the "crosswind runway" which was originally planned at time of opening of
the airport, will not be developed in the future, we will conduct necessary
reviews of the noise control zone regulated by the Noise Prevention Act andnecessary transitional measures to be taken with reference to a case example
of another airport wherein such zone has been reduced.
• While the noise contours will not be expected to increase alongside Runway A,
the current noise control zone will be maintained in terms of preserving theresidentʼs living environment.
• For the current noise control zone on the south side of Runway B, the current
countermeasure level will be maintained until the operation on the south side of
Runway B comes to an end in conjunction with Runway C becoming operational.

• On the assumption that those noise contours that NAA has newly suggested
will be used, we will examine and consult with relevant organizations to prepare
a flexible noise control zone regardless of the traditional operation.

■Increase the amount of grant for countermeasures in thesurrounding area
[Current] per household: 300,000 flights,
per landing fee: 230,000 flights (actual number)[Planned] per household: 500,000 flights,
per landing fee: 500,000 flights (airport capacity)• Allocation method of grant has been reviewed to provide a more effective
support towards development efforts by surrounding local governments.

■Countermeasures against falling object from aircraft

Noise contours
Noise contours for 500,000 annual ﬂights based on our revised plan
for relaxation of restrictions on night operation■The noise contours for 500,000 annual flights based on our revised plan for relaxation of restrictions on night flights are as
follows: 30 minute reduction in the operating hours has slightly decreased the range of such contours, as shown below.
■Plans of noise control zone regulated by the Noise Prevention Act *1 and Special Noise Countermeasures Act *2 will bemade based on these noise contours in view of wholeness of neighboring houses, landform, terrestrial objects, etc.

Measures for relocation• Drawing a noise contour that includes future increase of flights will provide alarger area applicable for compensation of relocation expenses based on the
Act on Special Measures concerning Countermeasures against Aircraft Noisearound Specified Airports.
• We will continue to sincerely consult with relevant organizations on possible
countermeasures against falling objects along with discussion on measures forco-prosperity and other various problems.
Support system for damage relief caused by falling objects from aircraft• We will create a support system where damage relief will be provided ("consolation
payment", "advance money payment", and "smooth support between local
residents and airlines") should any falling object from aircraft cause damages.

■Upgrade of the noise abatement works
Double pane window glass• As to the "double pane" window, we will consider
providing such as a part of the subsidized aid on thebasis of conforming to the standard specification.
More ﬂexible system to provide allowable limit ofamount, etc. according to the number of family
members per household• In the event that a head of a household is living alone
but has children or grandchildren, we will increase
the allowable limit of amount for noise abatement
wor k s or the like, giving c onsider ation to thetemporary return of such children or grandchildren.
Noise insulation work for outer walls of bathroom,
lavatory and toilet• When any noise abatement work for outer walls ofbathroom, lavatory and toilet is considered to be
more reasonable than noise abatement works forindoor fittings and fixtures, such works will be madeavailable within an allowable limit of amount.

■Countermeasures against late-night and early-morning ﬂight noise(installment of inner windows in bedrooms)
Installment of inner windows in bedrooms• We will install inner windows in residential bedrooms which are expected to havenoise reduction effect of about 35dB to 40dB when combined with the existing
noise abatement works to secure good quality sleep for residents of the local
community in conjunction with the relaxation of restrictions on night operation.
(Within the area over Lden 62db)• Inner windows will be installed for each bedroom based on the number of family
members who are currently residing in the house.
* In order to deal with the relaxation of restrictions on night operation in the near future,
this measure will be taken ahead of time in the noise control zone of Runway A.
Supplementary works for walls and ceilings of bedrooms• To maximize the beneficial effect of installation of the inner windows to the greatest
extent possible, we will conduct noise abatement works for walls and ceilings
where no such work has been conducted.
* In order to deal with the relaxation of restrictions on night operation in the near future,
this measure will be taken ahead of time in the noise control zone of Runway A.
Restriction imposed on aircraft type during late-night and early-morning hours• For those aircraft types that operate from 5:00 to 6:00 and after 23:00, aircraft types
that produce less noise* are only allowed to take off and land.
* The airplanes that conform to the noise index A for aircraft types in Narita Airport(B787, B747-8, A380, A320, etc.); B (B777, B767, etc.) and C (B737, etc.)

Internal windows will be set up in
bedrooms to improve the noise
reduction effect.

■Efforts for local community promotion and development capitalizingon the airport• We will consider a more effective support for the development efforts by municipal
government in the area under noise strain of a cer tain level by preferentiallyallocating a fixed amount of grant as "Regional Promotion Allocation" from theannual grant, with their financial capability taken into account.
• The Liaison Council of Regional Promotion will c arr y out a s tudy on loc altransportation around Narita Airport.
