Resumo:
This work intended to study the methodologies used for EIA and
propose the adaptation of a simplified matrix for the assessment of
environmental impacts regarding small hydropower plants.
A case study of Ninho da Águia SHP, located in the city of Delfim
Moreira, MG, was used for elaborating the matrix. The methodology used the
analysis of all the negative impacts and they were given combined weight
based on a pre-established impact scale. The weights that were given to each
impact were distributed according to the combination of features presented in
the referred EIA.
The results attained show that the environmental damage is reduced
by 45% when the mitigating measures suggested by the EIA and by the
analysis carried out by this study are applied. Besides, this preliminary
proposal will make it possible for environmental licensing process to be
accelerated. Today, this process is considered as an investment inhibiter
because of it takes too much time. Also, the proposal may be used as initial
guidelines regarding the environmental cost of the implementation of
enterprises. The proposed matrix shows itself as efficient because it is easy to
be used and it is a useful tool for the analysis of projects that will be
implemented.
