    We examined the possibility of simplifying the environmental impact assessment related to construction work of wind power plant in order to shorten the environmental assessment procedure for wind power plant. In this paper, it is clarified by using diffusion equations, that environmental impact of NO2 due to driving of construction vehicles and operation of construction machines are extremely small, in construction work of wind power plants. As results, we can say that individual environmental assessment procedure can simplify or omit prediction of NO2 under construction unless special circumstances exist. In addition, judging from the traffic volume of construction vehicles, the influence of the falling dust on the roadside by construction vehicles can be neglected excluding the vicinity of the construction site.

    There is no definitive definition of a positive assessment as determined under the local government system of environmental impact assessment (EIA). In this study, the term is used in the sense of a positive decision when a positive environmental impact is assessed. Two surveys of positive assessment are then conducted on the basis of this definition: a questionnaire for local governments that investigates how positive assessment is applied in actual operations; and a survey of how positive assessment is covered in the regulatory system as published in local government technical guidelines available on the Internet. On the basis of the surveys, usage of positive assessments under the current local government EIA system and related issues are then examined.
