The methodology used was based on bibliographic, scientific and technical research, field visits and photographic records. The georeferencing of the study area was performed using geoprocessing tools, then a simplified environmental diagnosis of the study's area of influence was prepared. Next, the identification and classification of environmental impacts was carried out, indicating environmental control measures and environmental plans and programs based on the classification of environmental impacts. According to the results obtained, 161 environmental impacts were found, 26 of which were non-significant, 80 significant and 55 very significant. 37 environmental aspects were also characterized.
