Análise do estudo de impacto ambiental da PCH Ninho da Águia. Proposta de otimização do processo de licenciamento ambiental utilizando uma matriz simplificada

Abstract

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.
