The law related to the regulations of vibrations was enacted in June, 1976. As a result, seven typical causes of pollution came almost wholly under legal restrictions. Efforts have been made to promote the regulations on and environmental preservation measures against traffic pollution such as auto-exhaust, noises from automotive traffic, new trunk lines and aircraft etc. and marine pollution respectively.
The prevention of traffic pollution can be effected by the following five
measures. First, the regulations on discharging environmental pollutants, such
as auto-exhaust and oils and wastes discharged from ships should be developed.
Secondly, each project should be planned and undertaken on the basis of integrated
judgments with full understanding of the desires of local self-governing h)dies.
When a project has large effects on the environment, such environmental effects
to the regions should be estimated in advance and the techniques for the assessment
of environmental effects including the environmental preservation measures should
be developed.
Thirdly, pollution problems caused by the development and operation of traffic
facilities are closely related to a site of concerned works and a surrounding
condition. So it is important to maintain harmony with a land utilization plan.
The fourth measure is related to the expenses' of pollution control. Huge expenses
are required for pollution control. So on the principle that, polluters must
bear the burden and make enterprises efforts, such expenses should be borne
by indirect polluters, namely, users. The fifth measure is development of pollution
control techniques, which is one of fundamental methods for solving pollution
problems.
